In September, satellite pictures showed more than 20000 fires burning in the Amazon. Experts say most of these fires were set by farmers. The farmers were attempting to clear land to grow crops. The World Wildlife Fund says another serious problem is that too many trees in the Amazon rain forest are being cut down. The World Wildlife Fund says the fires show the need for urgent international action to protect the world's rain forests. The group warns that without such action some forests could be lost forever.2. Environmental issues swell to the full in Berlin this week, for the UN spongsored conference on global warming and climate change is the first such meeting since the Rio summit three years ago. With scientists and governments now generally ready to accept that the earth climate is being affected by emissions of CO2 and other greenhouse gases, over a hundred countries are sending delegations. But how much progress has been made implementing the greenhouse gas reduction target agreed on at Rio? Simon Dary reports...Part II The Earth at risk (I)A.I (Interviewer): Brian Cowles is the producer of a new series of documentaries called "The Earth at Risk" which can be seen on Channel 4 later this month. Each program deals with a different continent, doesn't it, Brian?B (Brian Cowles): That's right. We went to America, both North and South and then we went over to Africa and South-East Asia.I: And what did you find in each of these continents?B: Starting with Africa, our film shows the impact of the population on the environment. Generally speaking, this has caused the Sahara Desert to expand. It's a bit of a vicious circle we find. People cut down trees for firewood and their domestic animals eat all the available plants —and so consequently they have to move south as the Sahara Desert expands further south. I mean, soon the whole of Mali will become a desert. And in East Africa: here the grasslands are supporting too many animals and the result is, of course, there's no grass —nothing for theanimals to eat.I: I see. And the next film deals with North America?B: That's right. In the USA, as you know, intensive agriculture requires a plentiful supply of rain for these crops to grow, I mean if there isn't enough rain the crops don't grow. And growing crops stabilize soil, without them the top soil just blows away. This is also true for any region that is intensely farmed — most of Europe, for example.I: And what did you find in South America?B: In South America (as in Central Africa and Southern Asia) tropical forests are being cut down at an alarming rate. This is done so that people can support themselves by growing food or to create ranches where cattle can be raised to be exported to Europe or America as tinned meat. The problem is that the soil is so poor that only a couple of harvests are possible before this very thin soil becomes exhausted. And it can't be fed with fertilizers like agricultural land in Europe. For example, in Brazil in 1982 an area of jungle the size of Britain and France combined was destroyed to make way for an iron ore mine. Huge numbers of trees are being cut down for exports as hardwood to Japan, Europe, USA to make things like luxury furniture. These forests can't be replaced — the forest soil is thin and unproductive and in just a few years, a jungle has become a waste land. Tropical forests contain rare plants (which we can use for medicines, for example) and animals —one animal or plant species becomes extinct every half hour. These forest trees also have worldwide effects. You know, they convert carbon dioxide into oxygen. The consequence of destroying forests is not only that the climate of that region changes (because there is less rainfall) but this change affects the whole world. I mean, over half the world's rain forest has been cut down this century.Part III The Earth at risk (II)A.I: So, Brian, would you agree that what we generally think of as natural disasters are in fact man-made?B: Yes, by and large. I mean, obviously not hurricanes or earthquakes, but take flooding, for example. Practically every year, the whole of Bangladesh is flooded and this is getting worse. You know, the cause is that forests have been cut down up in Nepal and India, I mean higher up-river in the Himalayas. Trees would hold rainfall in their roots, but if they've been cut down all the rain that falls in the monsoon season flows sraight into the river Ganges and floods the whole country. The reason for flooding in Sudan is the same — the forests higher up the Blue Nile in Ethiopia have been destroyed too.I: Well, this all sounds terribly depressing. Um ... What is to be done? I mean, can anything be done, in fact?B: Yes, of course it can. First, the national governments have to be forward-looking and consider the results of their policies in ten or twenty years, not just think as far ahead as the next election. Somehow, all the countries in the world have to work together on an international basis. Secondly, the population has to be controlled in some way: there are too many people trying to live off too little land. Thirdly, we don't need tropical hardwood to make our furniture — it's a luxury people in the West must do without. Softwoods are just as good, less expensive and can be produced on environment-friendly "tree farms", where trees are replaced at the same ratethat they are cut down.I: And, presumably, education is important as well. People must be educated to realize the consequences of their actions?B: Yes, of course.I: Well, thank you, BrianB.I: So, Brian, would you agree that what we generally think of as ... er... as er ... natural disasters are in fact man-made?B: Yes, by and large ... er ...

We know this because average temperatures are the highest since scientists started measuring them 600 years ago. The increase is about 0.2℃every year. This may seem very slight, but we know that slight changes in temperature can have a big effect on other things. Most scientists now believe this global warming is due to human activity.Jeff Jenkins is head of Britain's Climate Prediction Center. He explains how global warming can happen."Sunlight strikes the earth and warms it up. At the same time heat leaves the earth, but part of that is trapped by carbon dioxide and other gases in the earth's atmosphere. That has been happening ever since the earth was formed. But the fear is that increasing amounts of carbon dioxide produced by industrial processes and transport and so on will lead to a greater warming of the earth's surface. So that's the golbal warming that people are concerned about."People are most concerned about the use of fossil fuels. Fossil fuels are oil, coal, wood and so on. When these burn, they produce the gas carbon dioxide. Many scientists agree that an increase inthe amount of carbon dioxide and some of the gases in the atmosphere will increase the amount of warming. Computers are being used to predict what this may mean. They showed that there could be great changes in rainfall and the rise in the sea level as ice caps in the north and south poles melt. This could have a serious effect on agriculture according to Prof. Martin Perry of University College in London. He says it could become more difficult to grow food in the tropics at lower latitudes nearer to the equator."The most clear pattern emerging is the possibility of reduced potential production in lower latitude regions, and most generally speaking, increased potential in higher latitude regions. Lower latitude regions are already warm, to put it extremely simply, and plants there are quite near their limits of heat and drought stress. An increase in temperature or reduction in moisture would place limits on crop growth."Woman: Global warming could reduce food production in lower latitude regions. Lower latitude regions are already warm. Global warming could put more stress on plans and place limits on crop growth.Food production is only one area that could be affected. There could also be health and social problems. Prof. Antony MacMichael of the London School of Hygiene and Tropical Medicine believes that some rural areas are already suffering. And the insects and bacteria could spread disease more easily."Already a number of rural populations around the world are suffering from the decline of agricultural systems. Climate change would add to this. And we would expect that it would accelerate the flood of environmental refugees around the world. But it includes not just the food production systems, but the patterns of distribution of insects and infective agents around the world. It includes likely effects on patterns of hear-related food poisoning, water contamination and diarrhea diseases, lots of things like this that would respond sensitively to changes in climate."Woman: Global warming could affect the distribution of insects. Global warming could change patterns of heat-related food poisoning.Many countries now agree that something must be done to reduce the danger of global warming. But a worldwide agreement on lowering the production of carbon dioxide has been difficult to reach. This is because many economies depend on fossil fuels like oil. Scientists believe it's now the politicians in every region of the world who need to take action.Part V Do you know…?Environment has taken rather a back seat politically since the Earth summit in Rio de Janeiro nearly 5 years ago. But the problems that meeting highlighted had not gone away. One environmental think tank — the International Food Policy Research Institute — has been looking at the future of water and its report reflects growing concern at the huge leap in usage over the past few years.In some parts of the world, water consumption has increased five fold. And the institute, known by its initials IFPRI, says shortages could soon become the trigger for conflict and a major barrier to feeding the world's growing population. Here's Richard Black of our Science Unit."It's often been said that water rather than oil will be the cause of warfare in the next century. According to the IFPRI report, the time when that happens might not be far away. The number of people affected by water shortage will increase ten fold over the next 30 years, it says, whichcould well lead to large scale conflicts.The main reason why water is becoming a scarce resource is agriculture, which now accounts for 70% of water consumption worldwide, 90% in some developing countries. Countless farmers have switched from growing indigenous crops for the home market to high yield export varieties, which inevitably need far more water. But the IFPRI report says that in some regions water shortage is now the single biggest impediment to feeding the population. Water scarcity also leads to water pollution. In the Indian State of West Bengal, for example, over extraction of water from bore holes has led to arsenic poisoning which is estimated to have affected two million people so far. But the IFPRI report calls for better water management worldwide including financial incentives to encourage conservation."That report by Richard Black of our Science Unit.Unit 2Part I Getting readyA.B.

If you've got a few minutes I'd like to tell you what that means. B: Oh, all right.A: We work to conserve natural areas that contain endangered wildlife.

B: Very interesting.A: Aided by our campaign, protected nesting sites for turtles have already been set up. As you can see, this is very valuable work and I wonder therefore if you'd like to make a donation?Part II Christmas bird countsJohn James Audubon was an American artist in the early 1800s, who illustrated birds in their natural habitats. The Society named after him was founded in the late 1800s by conservationists concerned with the decline of birds, which were being killed so their feathers could be used in the manufacture of women's hats.Sponsored by the National Audubon Society, more than 40 000 volunteers will be outside counting birds from today until January 3rd. Volunteers from all 50 states of the United States, every Canadian province, parts of Central and South America, Bermuda, the West Indies and Pacific islands have begun to count and record every individual bird and bird species observed during the two and one half week period of the count.Jeffrey LeBaron is the National Audubon Society's Christmas Bird Count editor. He says the count is the longest-running bird census in ornithology.This year, according to Mr. LeBaron, more than 1 600 separate bird counts have been scheduled. Some would have as few as 10 people taking part, others with hundreds. The logistics of the Christmas bird count, he adds, are simple."Each individual count is in a circle. It's a 15 mile diameter circle, um, around the exact center point. And it's always the exactly same area that's done every year, usually, even on the same weekend during the count period. And what the ideal would be, which is virtually impossible, is this census: every single individual bird within that circle on the count day."Mr. LeBaron says experienced bird counters can get a good idea of the total bird populations within the count circle based on the number of birds they actually see. The editor points out, however, that the counts are not only for experienced bird watchers."Anybody that is interested or concerned can become involved. Beginners will go out in a party with experienced individuals who know both the area and the birds in the area, in the field where more eyes and ears are better. And then anybody can point out a bird, and someone in the field will always be able to identify the bird."Part III Dolphin captivityA: A planned aquatic park in Denver is raising the ire of animal rights activists who object to a proposal to include a captive dolphin display. Although officials for Colorado's Ocean Journeys say they have yet to make a final decision on the issue, local and national activists have already instigated a "No Dolphins in Denver' campaign. As Colorado Public Radio's Peter Jones reports, the battle lines have been clearly drawn.P: Rick Troud, a former navy dolphin trainer based in Florida, is taking an active role in the "No Dolphins" campaign.R: Average age in the wild ranges anywhere in some of the studies between 30 and 40 years of age. In captivity, you can expect a dolphin to live maybe 5.13 years, and every 7 years in captivity, the dolphin population is dead.P: According to Troud, there are many reasons why dolphins can't live full lives in captivity. R: If you take a look at where the real dolphin is in the real ocean, you find the dolphin who swims 40 miles a day, is very family-oriented. These animals are separated from theirmothers; that's a stress. You put them in a concrete tank where their sonar bounces off of walls, they can't swim in the same amount of time and direction that they can in the wild.P: Environmentalist and ocean explorer, Jean Michel Cousteau:J: There are some animals which reject captivity right away, and they're very suicidal. I've had one of those in my own arms for many days. The next morning when I came to take care of him, he was dead. And what he'd done was to swim as fast as he could from one end of the pool on ... to the other side and destroyed his head by hitting the wall. They have a very sophisticated brain. I don't think we have any rights to play with the lives of these animals. P: Cousteau's anti-captivity position is challenged by Dr. Deborah Duffield, a biology professor at Portland State College in Oregon. Her 1990 study compared captive dolphins to the wild population of Sarasota Bay, Florida. Among other findings, the study showed little if any difference in the average age of death. And Duffield says life is generally getting better for captive dolphins.D: The census data say that every time I do a census, I've got older and older animals in it as well as this normal age distribution that we've been looking at. So my feeling is that the trend in captivity has been that the group of animals that we're following are getting older, and if they continue to do that over the next five years, they will then indeed be older than the wild population.P: There is also a debate over the educational benefits of keeping marine mammals in captivity. According to Duffield, captive dolphins play an important role in our basic understanding of the animals.D: I firmly believe that we cannot learn anything about organisms that we share this world with if we do not understand how they live in an environment, and what they do, and that watching them go by in the wild will not do it. I cannot tell what an animal needs, unless I know how it operates, how it breeds, what it needs metabolically, and I can't learn that from animals in the wild.P: But Troud says the dolphin displays are anti-educational because the animals' natural behavior patterns are altered by captivity.R: In the wild, you don't have dolphins who beat each other to death. There are no dolphins that I've ever seen stranded on the beach, who are suffering from fractured skulls, fractured ribs or fractured jaws, as is the case in captivity.P: The Ocean Journey board will take all factors into consideration before making a final decision on whether to include dolphins in the park. For Colorado Public Radio, I'm Peter Jones.Part IV More about the topic: Birds----A Source of WealthMr. LeBaron says there are about 9 300 different known species of birds. Larger numbers of them live in the warmer climates. For example, more than 300 different species have been counted in Panama, while far fewer species are native to colder climates. Aside from their esthetic value, Mr. LeBaron says birds are important to the environment because they can signal changes in it."Birds are one of the best indicators that we have of the quality of the environment within the given area. Whether it is a relatively local area, or even primarily on the worldwide bases, they are one of the first things to be altered. They are quite sensitive to a habitat alteration or toother threats. And often times when birds are disappearing out of the area, it just means there is a degradation of the quality of the habitat within that area which will adversely affect everything in there including humans."National Audubon Society editor Jeffrey LeBaron calls the world's bird populations a source of wealth that humans must protect."People get so much pleasure out of looking at birds and listening to birds. And if they start disappearing just the er, the quality of life, um, may be not physically, but the mental quality of life can be degraded quickly."Jeffrey LeBaron says that while the National Audubon Society's annual Christmas bird counts show a decline in some species, many types of birds are actually increasing their populations.Part V Do you know…?Scientists have cataloged more than one and one-half million of the species that exist on Earth today. By some recent estimates, at least 20 times that many species inhabit the planet.Up to 100 species become extinct every day. Scientists estimate that the total number of species lost each year may climb to 40 000 by the year 2000, a rate far exceeding any in the last 65 million years.Around the world more than 3 500 protected areas exist in the form of parks, wildlife refuges and other reserves. These areas cover a total of about 2 million square miles (5 million square km, or 3% of our total land area).Today, more than 200 animal species in the United States are classified as endangered. More than 1 000 animal species are endangered worldwide.Little-noticed aquatic animals are in big trouble. In North America, a third of our fish species, two-thirds of our crayfish species and nearly three-quarters of the mussel species are in trouble. Unit 3Unit 3 El Nino? La Nina?Part ID. warmer/ green house effect / sea levels/ climate zonesAs 1998 ends and people look forward to the last year of the century, the World Almanac spoke with experts about what comes next. Almanac editorial director says the experts believe the next century will bring lots of changes.Warm, of course, that our climate is going to continue getting warmer. That’s the subject, by the way, of another new article on the 1999 World Almanac. The greenhouse effect, exactly what causes it, and what steps to be taken to, perhaps to alleviate global warmings. I’ve seen recently that 1998 is going to go down as the warmest year ever on record. And so that’s going to be a major issue of the next century, and possible tremendous consequences of the global warmings, whether it is rising sea levels affecting the coastal areas; changes in climate zones affecting what。

One of the 66 passengers heard a strange "miaow" when the plane landed in Copenhagen. Mechanics arrived immediately and the airline company phoned for an animal ambulance. The mechanics found the cat after eight hours' work. It had got into the air-conditioning system in Nairobi. The plane was twelve hours late leaving for Tokyo, costing the company £10,000. The cat was quite well after its experience and was given a large bowl of milk and a plate of fish.ExerciseDirections: Listen to the passage and find its topic sentence.The topic sentence is "A cat got on to a Scandinavian Airlines plane in Nairobi yesterday and cost the company about £."Section TwoListening ComprehensionPart 1 DialogueWhat a Coincidence!Storyteller: Talking of coincidences, did I tell you about what happened to me and Jeannie last holiday?Friend(s):No.Storyteller: We went on holiday in the States and we went to Mexico. Well, we were driving down to Mexico City. We were going to spend a few days in Palm Beach ... see the sea, look up an old friend, you know. As we left there we stopped at a garage for a car check ... oil, the water, the tires, all that ... petrol. And the mechanics spotted something. They said that our fuel pump was not working properly and it was quite serious ... it would cost a lot of money ... well, we were very worried.Friend(s): Were you insured?Storyteller: Well, no, we weren't and I didn't have that much money on me, you know. It was meant to be a cheap holiday. Well, just then, two men drove up and they said what's the problem? And, do you know? They were mechanics - it was such good luck. They looked at our car and they said, "There's nothing wrong with your car. Don't spend money on it. Just forget about it." Well, naturally, we were worried, but ... er, I thought ... I'll trust them, I think they're right. So, we drove on, we crossed the Mexican border and had a marvelous few days sightseeing there round Monterey.Friend(s):Oh, oh, brilliant ... jealous ...Storyteller: And then we went on and on to Mexico City. We drove about fortykilometers and then we saw a car with the same US number plates as the other car we'd seen in Palm Beach.Friend(s): You're joking!Storyteller: It was parked by the road, and the same two men who gave us the advice about our car were stuck with their car.Friend(s): Oh, no!Storyteller: So, we stopped and asked them what was wrong. And do you know? Their car had broken down for exactly the same reason: The fuel pump wasn't working! It was quite extraordinary .ExerciseDirections: Listen to the dialogue and decide whether the following statements are true (T) or false (F)Part 2 PassageCorporate Culturewell the employee "fits" the culture can make the difference betweenjob-search success and failure.guides how employees think, act, and feel.amount of time outside the office you're expected to spend with co-workers is part of the corporate culture.truth is that you will never really know the corporate culture until you have worked at the company for a number of months.should be a place where you can have a voice, be respected, and have opportunities for growth.Why should jobseekers care about a potential employer's corporate culture? Aren't there more important factors to consider, such as the job itself, salary and bonuses, and fringe benefits? These factors are indeed important, but increasingly career experts are talking about the importance of employee-employer fit in terms of culture, with the idea that how well the employee "fits" the culture can make the difference between job-search success and failure.What is corporate culture? At its most basic, it's described as the personality of an organization, or simply as "how things are done around here". It guides how employees think, act, and feel. Corporate culture is a broad term used to define the unique personality or character of a particular company or organization, and includes such elements as core values and beliefs, corporate ethics, and rules of behavior. Corporate culture can be expressed in the company's mission statement and other communications, in the architectural style or interior decoration(室内装饰) of offices, by what people wear to work, by how people address each other, and in the titles given to various employees.How does a company's culture affect you? In many, many ways. For instance:•The hours you work per day, per week, including options such as flextime and telecommuting.•The work environment, including how employees interact, the degree of competition, and whether it's a fun or hostile environment - or something in-between.•The dress code, including the accepted styles of attire* and things such as casual days.•The office space you get, including things such as cubicles*, window offices, and rules regarding display of personal items.•The training and skills development you receive, which you need both on the job and tokeep yourself marketable for future jobs and employers.•Onsite perks, such as break rooms, gyms and play rooms, daycare facilities, and more.perk=perquisite n. 特殊待遇，特权；工资外收入•The amount of time outside the office you're expected to spendwith co-workers.• Interaction with other employees, including managers and topmanagement.How do you uncover the corporate culture of a potential employer? The truth is that you will never really know the corporate culture until you have worked at the company for a number of months, but you can get close to it through research and observation. Understanding culture is a two-step process, starting with research before the interview and ending with observation at the interview.If you get a chance to meet with other employees, you can ask somequestions to try and geta handle on an organization's corporate culture. Such as:•What's it really like to work here?•What skills and characteristics does the company value?•How do people get promoted around here?•The bottom line is that you are going to spend a lot of time in the work environment ---and to be happy ,successful and productive, you’ll want to be in a place where you fit the culture ,a place where you can have avoice ,be respect and have opportunity for growth .Exercise A Pre-listening QuestionMany articles and books have been written in recent years about culture in organizations, usually referred to as "Corporate Culture". The dictionary defines culture as "the act of developing intellectual and moral faculties, especially through education". Some people define it as "the moral, social, and behavioral norms of an organization based on the beliefs, attitudes, and priorities of its members".Every organization has its own unique culture or value set. Most organizations don't consciously try to create a certain culture. The culture of the organization is typically created unconsciously, based on the values of the top management or the founders of an organization.Exercise B Sentence DictationDirections: Listen to some sentences and write them down. You will hear each sentence three timesExercise C Detailed ListeningDirections: Listen to the passage and complete the following paragraphs At its most basic, corporate culture is described as the personality of an organization. It guides how employees think, act, and feel. Corporate culture is a broad term used to define the unique personality or character of a particular company or organization, and includes such elements as core values and beliefs,corporate ethics, and rules of behavior. Corporate culture can also be expressedin the company's mission statement and other communications, in the architectural style or interior decoration of offices, by what people wear to work,by how people address each other, and in the titles given to various employees.A company's culture affects you in many ways, such as the working hours,the work environment, the dress code, the office space you get, the training andskills development you receive, onsite perks, the amount of time outside theoffice you're expected to spend with co-workers and interaction with other employees, including managers and top management.Exercise D After-listening DiscussionDirections: Listen to the passage again and discuss the following questions.truth is that you will never really know the corporate culture until you haveworked at the company for a number of months, but you can get close to itthrough research and observation. / Understanding culture is a two-step process, starting with research beforethe interview and ending with observation at the interview.If you get a chance to meet with other employees, you can ask some questions to try and get a handle on an organization's corporate culture.

But the top U.S. military officer, Admiral Mike Mullen, told ABC's Good Morning America television program Tuesday the taking and rescue of the American cargo ship captain led him to order a new effort to find ways to effectively deal with the pirates. Admiral Mullen and Defense Secretary Robert Gates say there is no purely military solution to the Somali piracy problem. Piracy continues to rise, even as navy ships from 16 nations patrol the area. And Gates said Monday that the problem is "probably going to get worse" until the international community can, in his words, "get something on land thatbegins to change the equation" for the "incredible number of poor people" in Somalia, some of whom turn to piracy.Efforts by some ship owners to secure their ships have had some success. They have installed barbed wire, removed ladders and changed their routes, among other steps. But there has been resistance to proposals to put armed guards on commercial ships. Corporations have paid tens of millions of dollars for the safe return of ships and their crews in the area in recent years. Last year, there were 111 piracy incidents in the region, triple the number the previous year. And this year, there have already been nearly 70 incidents.A. the US looking for new approaches to Somali piracyB.F, T ,F ,T ,FSection FourSupplementary ExercisePart1 Feature ReportIranian government TV says that the country's new nuclear energy chief, Ali Akbar Salehi is urging the West to end hostilities with Tehran and to start building trust."Legal and technical discussions about Iran's nuclear case have finished," he insists, "and there is no room left to keep this case open.""We hope," he added, "that more efforts will be made [by the West] to obtain mutual confidence, instead of the last six years of hostility."They were Salehi's first comments to the media, since being appointed by President Mahmoud Ahmedinejad, Friday, following the resignation of veteran nuclear negotiator Gholam Reza Aghazadeh.The soft-spoken Salehi was educated at the American University of Beirut and holds a doctorate from the Massachusetts Institute of Technology. Salehi is Iran's former envoy to the International Atomic Energy Agency and signed aprotocol allowing for freer inspections of Iran's nuclear sites. His appointment appears to be something of a gesture to the U.S.Neither the U.S., nor the other members of the so-called Group of five-plus-one, including the five permanent members of the United Nations Security Council, plus Germany, however, are likely to agree with Salehi about the closure of Tehran's nuclear file.. President Barack Obama warned Tehran, during the G-8 summit in Italy, that the world is giving it until September to comply with . resolutions over its controversial nuclear program.Iran has persistently refused to stop enriching uranium, and the West fears that it will use highly enriched uranium to build atomic weapons.The Iranian government, however, continues to insist that its nuclear program is intended for peaceful, civilian purposes, alone.Iran analyst Meir Javedanfar of the MEEPAS (Middle East Economic and Political Analysis) center in Tel Aviv argues that Tehran is hardening its position over its nuclear dossier, in response to Western criticism over its violent crackdown against its own people following the June 12 presidential elections."I think Ayatollah Khamenei is sending the message that the more we are pushed on other fronts, the more we're going to adjust the balance in our favor, and one area is the nuclear program, because Khamenei knows how important the nuclear program is to the West, especially to President Obama," he said."So, I think this is kind of a backlash against what Iran sees as Western interference in its own affairs. I also think that the Iranian government still sees the West as divided and there's not much the West can do at the moment to stop Iran's nuclear program, so they're toughening their policy and they want to see what the reaction will be, if the reaction is going to be hard or if the West is going to come up with an even [better] offer," he added.Javedanfar, however, believes that those who are seeking a compromise with Iran should not despair completely, because Iranian leaders are pragmatists, and may at the end of the day be ready for an agreement.Iranian Foreign Minister Manuchehr Motaki said one week ago that Tehran was preparing to present a "new package" of proposals, concerning what he called "international, security and political issues," to the West for talks.Iran's Supreme Leader Ayatollah Ali Khamenei has also warned the West that Tehran would weigh their criticism over its crackdown on protesters following the June 12 election, in assessing future relations with their countries.

It is not just some passing trend.3)Used properly, fire can cook food, sterilize equipment, form iron, and heatour homes. Used carelessly, it can destroy lives, towns and forests in aninstant.4)Globalization has dangers and an ugly dark side. But it can also bringtremendous opportunities and benefits.5)They will see globalization not as something to worship or demonize. Instead,they will see it as something to mold, shape and manage for the betterment of everyone.Globalization is the present worldwide drive toward a globalized economic system dominated by supranational* corporate trade and banking institutions that are not accountable to democratic processes or national governments.The World Trade Organization (WTO) is among the most powerful, and one of the most secretive international bodies on earth. It is rapidly assuming the role of global government, as 134 nation-states, including the US, have ceded* to its vast authority and powers. The WTO represents the rules-based regime of the policy of economic globalization. The central operating principle of the WTO is that commercial interests should supersede* all others. Any obstacles in the path of operations and expansion of global business enterprise must be subordinated. In practice these "obstacles" are usually policies or democratic processes that act on behalf of working people, labor rights, environmental protection, human rights, consumer rights, social justice, local culture, and national sovereignty.Globalization is not a phenomenon. It is not just some passing trend. Today it is an overarching international system shaping the domestic politics and foreign relations of virtually every country, and we need to understand it as such.As thoughtful people concerned about world affairs, our job is to pick up "globalization", examine it from all sides, dissect* it, figure out what makes ittick, and then nurture and promote the good parts and mitigate* or slow down the bad parts. Globalization is much like fire.Fire itself is neither good nor bad. Used properly, it can cook food, sterilize equipment, form iron, and heat our homes. Used carelessly, fire can destroy lives, towns and forests in an instant. As Friedman* says:"Globalization can be incredibly empowering and incredibly coercive*. It can democratize opportunity and democratize panic. It makes the whales bigger and the minnows* stronger. It leaves you behind faster and faster, and it catches up to you faster and faster. While it is homogenizing* cultures, it is also enabling people to share their unique individuality farther and wider."Globalization has dangers and an ugly dark side. But it can also bring tremendous opportunities and benefits. Just as capitalism requires a network of governing systems to keep it from devouring societies, globalization requires vigilance and the rule of law.Antitrust laws, the Securities and Exchange Commission, labor unions, charities, the Federal Trade Commission, and countless other agencies and organizations keep American capitalism in check. Similar transparent mechanisms are needed to make sure globalization is a positive force in the world.Globalization will always have cheerleaders who are blind to the destruction globalization can cause. And it will always have strident* opponents blind to the way globalization gives some people their first opportunity to fulfill basicaspirations.As with most issues, the majority of people will be in the middle. They will see globalization not as something to worship or demonize. Instead, they will see it as something to mold, shape and manage for the betterment of everyone.Exercise D After-listening DiscussionDirections: Listen to the passage again and discuss the following questions.1. Milton Friedman says, "Globalization can be incredibly empowering and incredibly coercive. It can democratize opportunity and democratize panic. It makes the whales bigger and the minnows stronger. It leaves you behind faster and faster, and it catches up to you faster and faster. While it is homogenizing cultures, it is also enabling people to share their unique individuality farther and wider."2.(Open)。

The Amaz on forests are disappeari ng because of in creased bur ning and tree removal. I n September, satellite pictures showed more tha n 20000 fires bur ning in the Amaz on. Experts say most of these fires were set by farmers. The farmers were attempting to clear land to grow crops. The World Wildlife Fund says another serious problem is that too many trees in the Amazon rain forest are being cut down. The World Wildlife Fund says the fires show the n eed for urge nt intern ati onal acti on to protect the world's rain forests. The group warns that without such action some forests could be lost forever.2. Environmental issues swell to the full in Berlin this week, for the UN spongsored conference on global warming and climate change is the first such meeting since the Rio summit three years ago. With scie ntists and gover nments now gen erally ready to accept that the earth climate is being affected by emissions of CO2 and other gree nhouse gases, over a hun dred coun tries are sending delegati ons. But how much progress has bee n made impleme nting the gree nhouse gas reducti on target agreed on at Rio? Sim on Dary reports...Part II The Earth at risk (I)A.I (Interviewer): Brian Cowles is the producer of a new series of documentaries called "The Earth at Risk" which can be see n on Channel 4 later this mon th. Each program deals with a differe nt con ti nent, does n't it, Bria n?B (Bria n Cowles): That's right. We went to America, both North and South and the n we went over to Africa and South-East Asia.I: And what did you find in each of these continents?B: Starting with Africa, our film shows the impact of the population on theen vir onment. Gen erally speak ing, this has caused the Sahara Desert to expa nd. It's abit of a vicious circle we find. People cut down trees for firewood and their domestic animals eat all the available pla nts —and so con seque ntly they have to move south as the Sahara Desert expands further south. I mean, soon the whole of Mali will become a desert. And in East Africa: here the grassla ndsare support ing too many animals and the result is, of course, there's no gras—nothing for the animals to eat. I: I see. And the next film deals with North America?B: That's right. In the USA, as you know, intensive agriculture requires a plentiful supply of rain for these crops to grow, I mean if there isn't eno ugh rain the crops don't grow. And growing crops stabilize soil, without them the top soil just blows away. This is also true for any regi on that is in ten sely farmed —most of Europe, for example. I: And what did you find in South America?B: In South America (as in Cen tral Africa and Souther n Asia) tropical forests are being cut down at an alarming rate. This is done so that people can support themselves by growing food or to create ranches where cattle can be raised to be exported to Europe or America as tinned meat. The problem is that the soil is so poor that only a couple of harvests are possible before this very th in soil becomes exhausted. And it can't be fed with fertilizers like agricultural la nd in Europe.For example, in Brazil in 1982 an area of jungle the size of Britain and France comb ined was destroyed to make way for an iron ore mi ne. Huge nu mbers of trees are being cut dow n for exports as hardwood to Japa n, Europe, USA to make things like luxury furniture. These forests can't be replaced —the forest soil is thin and un productive and in just a few years, a jun gle has become a waste land. Tropical forests con tai n rare pla nts (which we can use for medici nes, for example) and ani mals —one animal or plant species becomes extinet every half hour. These forest trees also have worldwide effects. You know, they con vert carb on dioxide into oxyge n. The con seque nee of destro ying forests is not only that the climate of that regi on cha nges (because there is less rain fall) but this cha nge affects the whole world. I mean, over half the world's rain forest has bee n cut dow n this cen tury.Part III The Earth at risk (II)A.I: So, Bria n, would you agree that what we gen erally thi nk of as n atural disasters are in fact man-made?B: Yes,by and large. I mean, obviously not hurrica nes or earthquakes, but take flooding, for example. Practically every year, the whole of Bangladesh is flooded and this is gett ing worse. You know, the cause is that forests have bee n cut dow n up in Nepal and In dia, I mean higher up-river in the Himalayas. Trees would hold rain fall in their roots, but if they've bee n cut dow n all the rain that falls in the monsoon seas on flows sraight into the river Ganges and floods the whole country. The reason for flooding in Sudan is the same —the forests higher up the Blue Nile in Ethiopia have bee n destroyed too.I: Well, this all sounds terribly depress ing. Um ... What is to be done? I mea n, can anything be done, in fact?B: Yes, of course it can. First, the national governments have to beforward-look ing and con sider the results of their policies in ten or twenty years, not just think as far ahead as the next election. Somehow, all the countries in the world have to work together on an intern ati onal basis. Secon dly, the populatio n has to be con trolled in some way: there are too many people trying to live off too little land. Thirdly, we don't need tropical hardwood to make our furniture ——it's a luxury people in the West must do without. Softwoods are just as good, less expe nsive and can be produced on en vir onmen t-frie ndly "tree farms", where trees are replaced at the same rate that they are cut dow n.I: And, presumably, education is important as well. People must be educated to realize the con seque nces of their acti ons?B: Yes, of course.I: Well, tha nk you, BrianB.I: So, Bria n, would you agree that what we gen erally thi nk of as ... er... as er ... natural disasters are in fact man-made?B: Yes, by and large ... er ...

People must be educated to realize the con seque nces ... um ... of their actions?B: Yes, yes of course.I: Well, thank you, Bria n.Part IV More about the topic: The Effects of Global Warmi ngThe world is warming up. We know this because average temperatures are the highest since scie ntists started measuri ng them 600 years ago. The in crease is about 02C every year. This may seem very slight, but we know that slight changes in temperature can have a big effect on other things. Most scientists now believe this global warmi ngis due to huma n activity.Jeff Jenkins is head of Britai n's Climate Predict ion Cen ter. He expla ins how global warm ing can happe n."Sunlight strikes the earth and warms it up. At the same time heat leaves the earth, but part of that is trapped by carb on dioxide and other gases in the earth's atmosphere. That has bee n happe ning ever since the earth was formed. But the fear is that in creas ing amounts of carb on dioxide produced by in dustrial processes and transport and so on will lead to a greater warming of the earth's surface. So that's the golbal warm ing that people are concerned about."People are most concerned about the use of fossil fuels. Fossil fuels are oil, coal, wood and so on. Whe n these burn, they produce the gas carb on dioxide. Many scie ntists agree that an in crease in the amount of carb on dioxide and some of the gases in the atmosphere will in crease the amount of warmi ng. Computers are being used to predict what this may mean. They showed that there could be great cha nges in rain fall and the rise in the sea level as ice caps in the north and south poles melt. This could have a serious effect on agriculture according to Prof. Martin Perry of University College in London. He says it could become more difficult to grow food in the tropics at lower latitudes n earer to the equator."The most clear pattern emerg ing is the possibility of reduced pote ntial product ion in lower latitude regi ons, and most gen erally speak ing, in creased pote ntial in higher latitude regions. Lower latitude regions are already warm, to put it extremely simply, and pla nts there are quite n ear their limits of heat and drought stress. An in crease in temperature or reduct ion in moisture would place limits on crop growth." Woma n: Global warmi ng could reduce food product ion in lower latitude regi ons. Lower latitude regi ons are already warm. Global warmi ng could put more stress on pla ns and place limits on crop growth.Food product ion is only one area that could be affected. There could also be health and social problems. Prof. Antony MacMichael of the London School of Hygie ne and Tropical Medicine believes that some rural areas are already suffering. And the in sects and bacteria could spread disease more easily."Already a number of rural populations around the world are suffering from the decline of agricultural systems. Climate change would add to this. And we would expect that it would accelerate the flood of environmental refugees around the world.

Scientists believe it's now the politicians in every region of the world who n eed to take action.Part V Do you know …？Environment has taken rather a back seat politically since the Earth summit in Rio de Jan eiro n early 5 years ago. But the problems that meeti ng highlighted had not gone away. One en vir onmen tal th ink tank —the Intern ati onal Food Policy Research Institute ——has been looking at the future of water and its report reflects growing concern at the huge leap in usage over the past few years.In some parts of the world, water con sumptio n has in creased five fold. And the institute, known by its initials IFPRI, says shortages could soon become the trigger for conflict and a major barrier to feeding the world's growing population. Here's Richard Black of our Scie nee Unit."It's often been said that water rather than oil will be the cause of warfare in the n ext cen tury. Accordi ng to the IFPRI report, the time whe n that happe ns might not be far away. The nu mber of people affected by water shortage will in crease ten fold over the n ext 30 years, it says, which could well lead to large scale con flicts.The main reas on why water is beco ming a scarce resource is agriculture, which now accounts for 70% of water consumption worldwide, 90% in some developing coun tries. Coun tless farmers have switched from grow ing in dige nous crops for the home market to high yield export varieties, which in evitably n eed far more water. But the IFPRI report says that in some regi ons water shortage is now the sin gle biggest impediment to feeding the population. Water scarcity also leads to water pollution. In the In dia n State of West Ben gal, for example, over extract ion of water from bore holes has led to arsenic poisoning which is estimated to have affected two million people so far. But the IFPRIreport calls for better water management worldwide in clud ing finan cial incen tives to en courage con servati on."That report by Richard Black of our Science Unit.Unit 2Part I Gett ing readyA.B.

The Society named after him was founded in the late0s by con servati oni sts concerned with the decli ne of birds, which were being killed so their feathers could be used in the manu facture of wome n's hats.Spon sored by the Nati onal Audub on Society, more tha n 40 000 volun teers will be outside counting birds from today until January 3rd. Volunteers from all 50 states of the United States, every Canadian province, parts of Central and South America, Bermuda, the West In dies and Pacific isla nds have beg un to count and record every in dividual bird and bird species observed duri ng the two and one half week period of the count.Jeffrey LeBaron is the National Audubon Society's Christmas Bird Count editor. He says the count is the Ion gest-r unning bird cen sus in orn ithology.This year, accord ing to Mr. LeBar on, more tha n 1 600 separate bird counts have bee n scheduled. Some would have as few as 10 people tak ing part, others with hun dreds. The logistics of the Christmas bird count, he adds, are simple."Each in dividual count is in a circle. It's a 15 mile diameter circle, um, around the exact center point. And it's always the exactly same area that's done every year, usually, eve n on the same weeke nd duri ng the count period. And what the ideal would be, which is virtually impossible, is this cen sus: every sin gle in dividual bird within that circle on the count day."Mr. LeBar on says experie need bird coun ters can get a good idea of the total bird populatio ns withi n the count circle based on the nu mber of birds they actually see. The editor points out, however, that the counts are not only for experieneed bird watchers."Anybody that is interested or concerned can become invoIved. Beginners will go out in a party with experie need in dividuals who know both the area and the birds in thearea, in the field where more eyes and ears are better. And then anybody can point out a bird, and some one in the field will always be able to ide ntify the bird."Part III Dolph in captivityA: A pla nned aquatic park in Den ver is raisi ng the ire of ani mal rights activists who object to a proposal to include a captive dolphin display. Although officials for Colorado's Ocean Journeys say they have yet to make a final decision on the issue, local and national activists have already instigated a "No Dolphi ns in Den ver' campaig n. As Colorado Public Radio's Peter Jones reports, the battle lines have bee n clearly draw n.P: Rick Troud, a former navy dolphin trainer based in Florida, is taking an active role in the "No Dolph ins" campaig n.R: Average age in the wild ran ges any where in some of the studies betwee n 30 and 40 years of age. In captivity, you can expect a dolph in to live maybe 5.13 years, and every 7 years in captivity, the dolph in populati on is dead.P: According to Troud, there are many reasons why dolphins can't live full lives in captivity.R: If you take a look at where the real dolphin is in the real ocean, you find the dolphin who swims 40 miles a day, is very family-oriented. These animals are separated from their mothers; that's a stress. You put them in a con crete tank where their son ar boun ces off of walls, they can't swim in the same amount of time and directi on that they can in the wild.P: Environmentalist and ocean explorer, Jean Michel Cousteau:J: There are some animals which reject captivity right away, and they're very suicidal. 「ve had one of those in my own arms for many days. The next morning when I came to take care of him, he was dead. And what he'd done was to swim as fast as he could from one end of the pool on ... to the other side and destroyed his head by hitting the wall. They have a very sophisticated brain. I don't think we have any rights to play with the lives of these animals.P: Cousteau's anti-captivity position is challenged by Dr. Deborah Duffield, a biology professor at Portla nd State College in Oreg on. Her 1990 study compared captive dolphins to the wild population of Sarasota Bay, Florida. Among other findings, the study showed little if any difference in the average age of death. And Duffield says life is gen erally gett ing better for captive dolph ins.D: The cen sus data say that every time I do a cen sus, I've got older and older animals in it as well as this normal age distribution that we've been looking at.So my feeling is that the trend in captivity has been that the group of animals that we're following are getting older, and if they continue to do that over the n ext five years, they will the n in deed be older tha n the wild populati on.P: There is also a debate over the educati onal ben efits of keep ing marine mammals in captivity. According to Duffield, captive dolphins play an importa nt role in our basic un dersta nding of the ani mals.D: I firmly believe that we cannot learn anything about organisms that we share this world with if we do not understand how they live in an environment, and what they do,and that watchi ng them go by in the wild will not do it. I cannot tell what an ani mal n eeds, uni ess I know how it operates, how it breeds, what it needs metabolically, and I can't leann that from animals in the wild.P: But Troud says the dolphin displays are anti-educational because theani mals' n atural behavior patter ns are altered by captivity.R: In the wild, you don't have dolph ins who beat each other to death. There are no dolph ins that「ve ever see n stra nded on the beach, who are sufferi ng from fractured skulls, fractured ribs or fractured jaws, as is the case in captivity.P: The Ocean Journey board will take all factors into consideration before making a final decision on whether to include dolphins in the park. For Colorado Public Radi o,I'm Peter Jon es.Part IV More about the topic: Birds——A Source of WealthMr. LeBar on says there are about 9 300 differe nt known species of birds. Larger nu mbers of them live in the warmer climates. For example, more tha n 300 differe nt species have bee n coun ted in Pan ama, while far fewer species are n ative to colder climates. Aside from their esthetic value, Mr. LeBaron says birds are important to the en vir onment because they can sig nal cha nges in it."Birds are one of the best indicators that we have of the quality of the environment within the given area. Whether it is a relatively local area, or even primarily on the worldwide bases, they are one of the first things to be altered. They are quite sensitive to a habitat alteration or to other threats. And often times when birds are disappearing out of the area, it just means there is a degradation of the quality of the habitat within that area which will adversely affect everything in there in clud ing huma ns."National Audubon Society editor Jeffrey LeBaron calls the world's bird populati ons a source of wealth that huma ns must protect."People get so much pleasure out of look ing at birds and liste ning to birds. And if they start disappearing just the er, the quality of life, um, may be not physically, but the mental quality of life can be degraded quickly."Jeffrey LeBaron says that while the National Audubon Society's annual Christmas bird counts show a decline in some species, many types of birds are actually in creas ing their populati ons.Part V Do you know …？Scientists have cataloged more than one and one-half million of the species that exist on Earth today. By some rece nt estimates, at least 20 times that many species in habit the pla net.Up to 100 species become extinct every day. Scientists estimate that the total nu mber of species lost each year may climb to 40 000 by the year 2000, a rate far exceedi ng any in the last 65 millio n years.Around the world more tha n 3 500 protected areas exist in the form of parks, wildlife refuges and other reserves. These areas cover a total of about 2 millio n square miles (5 millio n square km, or 3% of our total la nd area).Today, more than 200 animal species in the United States are classified as endan gered. More tha n 1 000 animal species are endan gered worldwide.Little-noticed aquatic animals are in big trouble. In North America, a third of our fish species, two-thirds of our crayfish species and nearly three-quarters of the mussel species are in trouble.Unit 3Unit 3 El Ni no?

You know I was born in Lausanne*, Switzerland; my father was Swiss-French Swiss and my mother was American, so, of course, we spoke both languages at home and I grew up bilingual. Then, of course, I learnt German at school - in Switzerland that's normal. And because I was already fluent in English, my second language at school was Italian. So I had a real head start*!Interviewer: So that's ... one, two, three, four - you had learnt four languages by the time you left school? How fluent were you?Suzanne: Urn, I was native speaker standard in French and English, but I'd become a bit rusty* in German and my Italian was only school standard. I decided the best option was to study in the UK, and I did Hispanic Studies at university, studying Spanish and Portuguese, with some Italian, and living in Manchester. Then I went to live in Brazil for two years, teaching English. Interviewer: So by this time you must have been fluent in six languages?Suzanne: Nearly. My Italian wasn't perfect, but I had a boyfriend from Uruguay* while I was there, so my Spanish also became pretty good!Interviewer: And then what did you do?Suzanne: When I was 25 I came back to Switzerland, went to an interpreters' school and then got a job in the United Nations when I was 28.Interviewer: And you've been there ever since?Suzanne: Not quite. In the first few months I met Jan, a Czech interpreter, who became my husband. We went to live in Prague in 1987 and that was where I learnt Czech.Interviewer: And the eighth language?Suzanne: Well, unfortunately the marriage didn't last; I was very upset and I decided to take a long break. I went to Japan on holiday, got a job and stayed for two years, which was when I learnt Japanese.Interviewer: That's amazing! And now you're back at the United Nations?Suzanne: Yes. Well, I never really left. I carried on doing work for them when I was in Prague -some in Prague, some in Austria and Switzerland, and I took a "sabbatical*" to work in Japan. They need people who can understand Japanese. But, yes, I've been back with them full-time for two years now.Interviewer: And your plans for the future?Suzanne: I'm going to learn more Oriental languages. It was such a challenge learning Japanese -it's so different from all the others. So I'll spend another two or three years here with the UN full-time, during which time I hope to get a substantial promotion, then I think I'll go back and learn Korean, or perhaps Chinese, and Thai - I'd love to learn Thai. And then, perhaps an Indian language. Whatever, I want to be fluent in another three or four languages before 45.ExerciseDirections: Listen to the dialogue and decide whether the following statements are true (T) or false (F).l.T 2.F 3.F 4.F 5.T 6.F 7.T 8.T 9. T 10. FPart 2 PassageThe Clyde RiverSalmon are very sensitive to environmental conditions and require cool, well-oxygenated water to thrive.The closure of factories that had poured toxins and other pollutants into the river boosted water quality significantly and modern sewage processing plants helped eliminate some of the foul smells.The river's depth and navigability helped make Glasgow an important center for importing tobacco, sugar and cotton from the Americas starting in the 1600s.The mills and factories that lined the Clyde made steel, textiles and chemicals, tanned leather and even produced candy and brewed alcohol.When the factories began to close in the second half of the 20th century, working-class Glasgow, Scotland's largest city, gained a reputation for social deprivation and rough streets.Running through one of Britain's biggest manufacturing centers, Glasgow, the Clyde River* was poisoned for more than a century by the fetid* byproducts of industry.The waterway bore the brunt of Glasgow's economic success during the Industrial Revolution and beyond, as pollution and chemicals destroyed its fish and wildlife populations and brewed smells whose memory still makes residents wince*. Now, with heavy industry gone and Glasgow reconceived as a center for culture and tourism, the Clyde is coming back to life.For the first time since the late 1800s, its native salmon have returned in sizable numbers, reflecting the new cleanliness of a river that was once one of Britain's filthiest.The Clyde River Foundation surveyed fish populations last autumn at 69 sites in the Clyde and its tributaries, and found salmon in seven of the nine major tributaries.The migratory fish, which vanished from the Clyde around 1880 after a long decline, first reappeared in the 1980s, but last year's survey was the first to show they've come back in healthy numbers.Although commercial salmon fishing was never widespread on the Clyde, the fish's return is symbolically important for Glasgow, where salmon were once so important to the city's identity that two are pictured on its official coat of arms.The salmon's comeback is also a sign of big improvements to water quality. Like sea trout, which have also reappeared in the Clyde system in recent years, salmon are very sensitive to environmental conditions and require cool, well-oxygenated* water to thrive.The decline of Glasgow's main industries helped boost the fortunes of a river that was essentially fishless for decades during the worst periods of pollution.The closure of factories that had poured toxins* and other pollutants into the river boosted water quality significantly. Environmental regulators also lightened dumping rules, and modern sewage processing plants helped eliminate some of the foul* smells that once tainted* the air.With worries rising about the environmental impact of enormous fish farms elsewhere in Scotland and severely depleted fish stocks in the North Sea and North Atlantic, the Clyde comeback is a rare bit of good news for Scotland's fish lovers.Since the area that is now Glasgow was first settled around the year 550, the Clyde has been central to its history.The river's depth and navigability helped make Glasgow an important center for importing tobacco, sugar and cotton from the Americas starting in the 1600s. Later, during the IndustrialRevolution that began in the late 1700s, Glasgow became a center of British shipbuilding and one of the country's great manufacturing centers.The mills and factories that lined the Clyde made steel, textiles and chemicals, tanned leather and even produced candy and brewed alcohol.When the factories began to close in the second half of the 20th century, working-class Glasgow, Scotland's largest city, gained a reputation for social deprivation* and rough streets. More recently, its art museums and nightlife have helped drive an economic comeback that has turned the city into a popular tourist destination.Exercise A Pre-listening QuestionRivers are important to humans because they supply fresh drinking water, serve as home for important fishes, and provide transportation routes.Exercise B Sentence DictationDirections: Listen to some sentences and write them down.

For most people in these countries, formally joining the West represents the fulfillment of lifelong dreams. Eastward expansion is not the only issue to be discussed at the Prague Summit. Many people believe the political and military alliance, created after World War II to provide a collective security system for the ten West European countries and the United States and Canada, lost its purpose with the collapse of the Soviet Union - for many years its only threat.NATO expansion and its post-Cold War role have been the subject of endless debate on both sides of the Atlantic, especially after the terrorist attacks on the United States.A possible war in Iraq is also high on the Prague agenda. Critics in the United States note few of the current candidates for membership have military forces that can contribute significantly to the new form of conflict. Some observers cite the importance of even minimal contributions, such as participating in NATO border defense, surveillance* or peace-keeping operations. Exercise ADirections: Listen to the news item and complete the summary.This news item is about the NATO eastward expansion and its military contribution.Exercise BDirections: Listen to the news again and complete the following passage.At the Prague Summit many people believe the political and military alliance, created after World War II to provide a collective security system for the ten West European countries and the United States and Canada, lost its purpose with the collapse of the Soviet Union - for many years its only threat.Another item on the Prague agenda is a possible war in Iraq. Critics in the United States note that the new comers have no military forces that can /contribute significantly to the new form of conflict. Some observers cite the importance of even minimal contributions, such as participating in NATO border defense. surveillance or peace-keeping operations.News Item2NATO SummitOne month and one day before the Prague summit, President Bush met with the NATO Secretary General George Robertson and praised the alliance. At the time, Mr. Robertson described the Prague meeting as "a transformational summit", perhaps the most important in the history of the alliance.It is a transformation that began with the end of the Cold War, and gained momentum with the September 11th terrorist attacks on the United States.Just days after hijacked planes rammed into the World Trade Center and the Pentagon, NATO voted to invoke its charter and help defend the United States. The Bush administration thanked the alliance, asked for NATO help with surveillance flights over the east coast, and then proceeded to launch a war on terrorism outside the structure of the alliance.At the Prague meeting -the first NATO summit since the terrorist attacks on America -the alliance will take up the creation of a rapid deployment force which could be deployed outside Europe. Members will be asked to commit units with specialty skills that can be used in unique situations such as forces trained in dealing with chemical weapons or the special challenges of fighting in rugged* mountains.Exercise ADirections: Listen to the news item and complete the summary.This news item is about NATO's Prague Summit and its help to the USA.Exercise BDirections: Listen to the news again and answer the following questions.One month and one day before the Prague summit, President Bush met with the NATO Secretary General.When meeting with President Bush, the NATO Secretary General described the Prague summit as "a transformational summit", perhaps the most important in the history of the alliance.

News Item3Putin-Bush SummitPresidents Bush and Putin ended their talks with a joint statement in which they said Iraq must comply with UN demands to disarm or face major consequences.They stressed Iraqi leader Saddam Hussein must comply fully and unconditionally with the latest Security Council disarmament resolution, and they expressed concern about the proliferation* of weapons of mass destruction.Russia backed the UN resolution as one of the five permanent members of the Security Council. But Moscow does not support the use of force against Iraq.At the end of their meeting in an 18th-century castle near the St. Petersburg airport, Mr. Putin said he still hopes diplomatic pressure will produce results. And he urged President Bush to continue to work through the UN.Their statement on Iraq bears a striking resemblance to the language approved by the 19 NATO member countries at the Prague summit. Mr. Bush told reporters that it is important to assure Russia that it has nothing to fear from NATO expansion.Exercise ADirections: Listen to the news item and complete the summary.This news item is about the talks between the US president and the Russian president.

TSection Four Supplementary ExercisesPart 1Feature ReportBush’s Arrival in EuropeAir Force One touched down on a cool, rainy summer's night at a military base outside London. Mr. Bush said nothing to reporters during the more than seven-hour flight from Washington, and he left the air base without making any remarks.But before he left the White House, the president said he will stand firm on his positions on global warming and missile defense. They are issues that have divided America and its European allies. And the prospects for a quick resolution are as gloomy as the skies that greeted his arrival on European soil.These are issues sure to be discussed at length on the sidelines of the Genoa* summit meeting. The leaders of the world's seven largest industrialized countries plus Russia have put the plight* of the world's poorest nations at the top of their formal agenda. But no one expects to avoid the controversiesGenerated by President Bush's opposition to the Kyoto* climate treaty, and his plan to develop a missile defense system. iIn an interview with foreign journalists prior to his departure for London, Mr. Bush talked about the dispute over the Kyoto protocol. He said some leaders have been more sympathetic to his view than others. And he said he will seek to reassure critics that the United States is seeking viable* alternatives to the agreement, which calls for mandatory* controls on emissions of certain gases, such as carbon dioxide.His talks Thursday with British Prime Minister Tony Blair could provide a clue of what lies ahead. The two will meet at Chequers, Mr. Blair's official residence in the British countryside. Aspokesman for the Prime Minister indicates on global warming and missile defense the two leaders may simply agree to disagree.It will be a serene* spot for a meeting. All indications at the reception awaiting the G-8 summit participants in Genoa will be quite the opposite.About a hundred thousand protestors are expected and elaborate security measures are in place in the Italian port city. President Bush says he can't quite understand what motivates the demonstrators. In his interview with foreign reporters, he said their aggressive protest tactics do more harm than good. He added their anti-trade stance* would lock people into* poverty. Exercise ADirections: Listen to the news report and complete the summary.This news report is about the attitudes of President Bush and the US government towards the issues of global warming and missile defense.Exercise BDirections: Listen to the news again and complete the following passage.Mr. Bush arrived in London for a short visit before the G-8 summit in Genoa.But before he left the White House, the president said he will stand firm on his positions on global warming and missile defense, the issues that have divided America and its European allies and are sure to be discussed at length at the Genoa summit meeting.The leaders of the world's seven largest industrialized countries plus Russia have put the plight of the world's poorest nations at the top of their formal agenda. But no one expects to avoid the controversies generated by President Bush's opposition to the Kyoto climate treaty; and his plan to develop a missile defense system.Mr. Bush defended his stance by saying that the United States is seeking viable alternatives to the agreement, which calls for mandatory controls on emissions of certain gases, such as carbon dioxide.About a hundred thousand protestors are expected and elaborate security measures are in place in the Italian port city.Part 2 PassageCorn PlasticsThe sugar is fermented and distilled to extract the carbon, a basic building block for commercial-grade plastics and fibers.Perhaps the greatest appeal of corn plastics is their green credentials. They go back to nature in 40 days.The biggest demand for corn plastics has been outside the United States, where packing components are developed for many products exported to America.Corn-based plates are about 5 percent more expensive than traditional plastic, and the cups can be 25 percent more costly.5) A billion pounds of PLA can be harvested annually within a decade, which would mean 10 percent of America’s corn supply would be into plastics and fiber.sCorn plastic are being developed by Cargill Dpw LLC at its plant outside Blair,where refined corn suger is converted into a substance called polyactide or PLA . . The sugar is fermented* and distilled* to extract the carbon, a basic building block for commercial-grade plastics and fibers. PLA, in pellets* the size of 0.46 centimeters in diameter, is being pressed into packaging for food, plastic wrap, foam and dinner ware. It is spun into fabrics at plants in North Carolina, Hong Kongand several cities in Japan, and marketed under the Ingeo* brand of clothing and blankets. Cargill Dow, a joint venture between privately held food giant Cargill Inc. and Dow Chemical Co., says Ingeo means "ingredients from the Earth".DuPont Co. is in the early stages of developing a similar product, but it still includes some petroleum. The company is part of a consortium* that received US$19 million from the US Department of Energy to develop a way to turn stocks, stems and leaves into a polymer* from which plastic can be made.Perhaps the greatest appeal of plastics is their green credentials. It takes about a month for plastic bags made from to degrade in a compost. A similar oil-based plastic bag could take centuries to decompose.Coca~Cola Co. used 500,000 cups made from plastics at the Winter Olympics in Salt Lake City last year. Instead of creating a large trash problem, used cups were simply composted and quickly turned into dirt."The product performed beautifully. They go back to nature in 40 days," said Frederic Scheer, president of Los Angeles-based Biocorp North America, which supplied the cups.The biggest demand for plastics has been outside the United States, including China's Taiwan island, where packing components are developed for many products exported to America. Taiwan bans petroleum-based plastic shopping bags and disposable plastic tableware. Electronics giant Sony Corp was involved in the early development of plastics and has wrapped its mini discs in a -based film made by Cargill Dow for two years. Cargill Dow also reached an agreement with Taiwan-based Wei Mon Industry to distribute -plastic packaging materials.IPER, one of Italy's largest supermarket chains, has been working with the natural-based packaging from Cargill Dow for nearly a year for film containers and heat-sealable film overlays. The -based plastic is more costly now. Biocorp North America*'s -based plates are about 5 percent more expensive than traditional plastic, and the cups can be 25 percent more costly. But Scheer said the price will decline as production goes up with demand - which he expects to see within five years. That could amount to a highly productive and new use of America's supply, which is so abundant that it is widely converted into -based sweeteners and animal feed.Cargill Dow believes a billion pounds of PLA can be harvested annually within a decade. That would mean 10 percent of America's supply would be converted into plastics and fibers. Exercise A Pre-listening QuestionCom starch is used primarily as a thickener. Sweeteners generated in the -refining process are used as sugar substitutes. Refined oil is used as cooking oil and producers of margarine, salad dressings, shortening, mayonnaise and other foods. The second major refined corn product is ethanol, which is gaining increasing acceptance as a cleaner burning option for motor fuels. The latest development in this field is the making of corn-based bio-chemical products like corn plastic and fiber.Exercise B Sentence DictationDirections: Listen to some sentences and write them down. You will hear each sentence three times.Exercise C Detailed ListeningDirections: Listen to the passage and answer the following questions.Corn plastics are being developed by Cargill Dow LLC at its plant outside Blair.The substance is called polylactide or PLA."Ingeo" is a brand of plastic fabrics made from corn sugar and it means "ingredients from the Earth".It takes about a month for plastic bags made from corn to degrade in a compost. A similar oil-based plastic bag could take centuries to decompose.Coca-Cola Co. used 500,000 cups made from corn plastics at the Winter Olympics in Salt Lake City.Many corn-plastic products are mentioned, such as cups and plates, shopping bags, packing components and packaging materials, film containers and heat-sealable film overlays. Probably because the production is still low now and the price will decline as production goes up with demand - possibly within five years.Cargill Dow believes a billion pounds of PLA can be harvested annually within a decade. Exercise D After-listening DiscussionDirections: Listen to the passage again and discuss the following questions..Frederic Scheer said the price will decline as production goes up with demand - which he expects to see within five years. That could amount to a highly productive and new use of America's corn supply, which is so abundant that it is widely converted into corn-based sweeteners and animal feed.(Open)。

No hard evidence exists to support that tale, but in any case, by the sixth Awards Presentation in 1934, a Hollywood columnist used the name in his column.3. Walt Disney was honored with one full-size and seven miniature statuettes on behalf of his animated feature Snow White and the Seven Dwarfs.1.T hey are possibly boyfriend and girlfriend.2.In a restaurant.3."It doesn't really matter, does it?

If the statuettes don't meet strict quality control standards, they are immediately cut in half and melted down.5.The large boxes are shipped to the Academy offices via air express, with no identifiable markings.The Oscar statuette, designed by MGM's* chief art director Cedric Gibbons, depicts* a knight holding a crusader's* sword, standing on a reel of film with five spokes, signifying the original branches of the Academy: Actors, Writers, Directors, Producers, and Technicians.Born in 1928, years would pass before the Academy Award of Merit was officially named "Oscar". Industry insiders and members of the press called the award "the Academy statuette", "the golden trophy" or "the statue of merit". The entertainment trade paper, Weekly Variety, even attempted to popularize "the iron man". The term never stuck.A popular story has been that an Academy librarian and eventual executive director, Margaret Herrick, thought the statuette resembled her uncle Oscar and said so, and that as a result the Academy staff began referring to it as Oscar.No hard evidence exists to support that tale, but in any case, by the sixth Awards Presentation in 1934, Hollywood columnist Sidney Skolsky used the name in his column in reference to Katharine Hepburn's first Best Actress win. The Academy itself didn't use the nickname officially until 1939.Since its conception, the Oscar statuette has met exacting uniform standards - with a few notable exceptions. In the 1930s, juvenile players received miniature replicas* of the statuette; a ventriloquist* Edgar Bergen was presented with a wooden statuette with a moveable mouth; and Walt Disney was honored with one full-size and seven miniature statuettes on behalf of his animated feature Snow White and the Seven Dwarfs. Between 1942 and 1944, in support of the war effort, Oscars were made of plaster. After the War, winners turned in the temporary awards for golden Oscar statuettes.The traditional Oscar statuette, however, hasn't changed since the 1940s, when the base was made higher. In 1945, the base was changed from marble to metal and in 1949, Academy Award statuettes began to be numbered, starting with No. 501.Approximately 50 Oscars are made each year in Chicago by the manufacturer, R. S. Owens. If they don't meet strict quality control standards, the statuettes are immediately cut in half and melted down.Each award is individually packed into a Styrofoam* container slightlylarger than a shoebox.Eight of these are then packed into a larger cardboard box, and the large boxes are shipped to the Academy offices in Beverly Hills via air express, with no identifiable markings.On March 10, 2000, 55 Academy Awards mysteriously vanished en route from the Windy City* to the City of Angels. Nine days later, 52 of stolenstatuettes were discovered next to a Dumpster* in the Koreatown section of Los Angeles by Willie Fulgear, who was later invited by the Academy to attend the Oscar 2000 ceremonies as a special guest.For eight decades, the Oscars have survived war, weathered earthquakes, and even managed to escape unscathed* from common thieves. Since 1995, however, R. S. Owens has repaired more than 160 statuettes. "Maybe somebody used chemicals on them to polish them and the chemicals rubbed right through the lacquer* and into the gold," explains the company president. "Or maybe people stored them someplace where they corroded." Although he stresses that the statuette is made to endure, Siegel offers this sage advice to all Oscar winners: "If it gets dusty, simply wipe it with a soft dry cloth." Exercise A Pre-listening QuestionEvery January, the attention of the entertainment community and of film fans around the world turns to the upcoming Academy Awards, the highest honor in filmmaking. The annual presentation of the Oscars has become the Academy of Motion Picture Arts and Sciences' most famous activity.

This guy is a dictator and so we have to seewhat he says." The president says the Iraqi leader has a choice to make: disarm peacefully or be disarmed by force: "If Saddam Hussein does not comply to the detail of the resolution, we will lead a coalition to disarm him. It is over. We are through with negotiations. There is no more time. The man must disarm. He said he would disarm. He now must disarm." Mr. Bush spoke with reporters while touring the Washington D.C. police department, a tour designed to highlight his plan to create a cabinet level Department of Homeland Security. He left no doubt his patience regarding Iraq is wearing very thin*, stressing the United States will no longer tolerate any efforts by Saddam Hussein to circumvent* demands to disarm.

In an interview with Radio Monte Carlo's Arabic service Thursday, Mr. Blair said war could be avoided, if Iraq agreed to disarm."The situation is very clear. If Saddam Hussein agrees to disarm Iraq of all chemical, or biological or nuclear weapons programs and capability, then conflict would be avoided, and his duty is to cooperate fully with the inspectors to tell them exactly what material he has, to cooperate and comply with them in the eradication of that material."The prime minister said he wanted to speak directly to the Iraqi people to try to dispel* what he called myths that have arisen between Christians and Muslims. He said the dispute with Iraq is not about the West versus the East or about oil, but about weapons of mass destruction.Exercise ADirections: Listening to the news item and complete the summary.This news item is about British Prime Minister's stand on the Iraqi issue.Exercise BDirections: Listen to the news again and complete the following sentences.1.Prime Minister Blair warned that Saddam Hussein would suffer theconsequences unless he cooperated with the UN weapons inspectors.

The Security Council gave Iraq this last opportunity to disarm or face serious consequences, a euphemism* for possible war. The United States says it will make sure Iraq disarms, one way or another.But Mr. Blix* emphasizes that his inspectors will not determine the courseof events in the region. He says they will visit suspected sites, conduct interviews with Iraqi scientists, ferret* out information and report back to the Security Council for its members to decide.As for US and British intelligence reports, which the Bush administration says proves that Iraq has banned weapons, Mr. Blix says he is not going into Iraq with pre-conceived ideas of what is there.The next test for Iraq will be December 8th, the deadline for Iraq to present a full accounting of its weapons programs. If Iraq presents, in effect, a blank sheet, Mr. Blix says, he would expect the United States to put its evidence on the table, so it can be verified.Iraq has persistently maintained it does not have the banned weapons. The latest such assertion came in a letter to the UN this week, in which Baghdad accepted the latest Security Council resolution setting out the parameters* for what experts say will be the most intrusive inspections in Iraq, so far.After the preliminary technical work starting Monday, Mr. Blix says, he expects the first wave of inspections to start November 27th.

You know I was born in Lausanne*, Switzerland; my father was Swiss-French Swiss and my mother was American, so, of course, we spoke both languages at home and I grew up bilingual. Then, of course, I learnt German at school - in Switzerland that's normal. And because I was already fluent in English, my second language at school was Italian. So I had a real head start*!Interviewer: So that's ... one, two, three, four - you had learnt four languages by the time you left school? How fluent were you?Suzanne: Urn, I was native speaker standard in French and English, but I'd become a bit rusty* in German and my Italian was only school standard. I decided the best option was to study in the UK, and I did Hispanic Studies at university, studying Spanish and Portuguese, with some Italian, and living in Manchester. Then I went to live in Brazil for two years, teaching English. Interviewer: So by this time you must have been fluent in six languages?Suzanne: Nearly. My Italian wasn't perfect, but I had a boyfriend from Uruguay* while I was there, so my Spanish also became pretty good!Interviewer: And then what did you do?Suzanne: When I was 25 I came back to Switzerland, went to an interpreters' school and then got a job in the United Nations when I was 28.Interviewer: And you've been there ever since?Suzanne: Not quite. In the first few months I met Jan, a Czech interpreter, who became my husband. We went to live in Prague in 1987 and that was where I learnt Czech.Interviewer: And the eighth language?Suzanne: Well, unfortunately the marriage didn't last; I was very upset and I decided to take a long break. I went to Japan on holiday, got a job and stayed for two years, which was when I learnt Japanese.Interviewer: That's amazing! And now you're back at the United Nations?Suzanne: Yes. Well, I never really left. I carried on doing work for them when I was in Prague -some in Prague, some in Austria and Switzerland, and I took a "sabbatical*" to work in Japan. They need people who can understand Japanese. But, yes, I've been back with them full-time for two years now.Interviewer: And your plans for the future?Suzanne: I'm going to learn more Oriental languages. It was such a challenge learning Japanese -it's so different from all the others. So I'll spend another two or three years here with the UN full-time, during which time I hope to get a substantial promotion, then I think I'll go back and learn Korean, or perhaps Chinese, and Thai - I'd love to learn Thai. And then, perhaps an Indian language. Whatever, I want to be fluent in another three or four languages before 45.ExerciseDirections: Listen to the dialogue and decide whether the following statements are true (T) or false (F).l.T 2.F 3.F 4.F 5.T 6.F 7.T 8.T 9.

Now, with heavy industry gone and Glasgow reconceived as a center for culture and tourism, the Clyde is coming back to life.For the first time since the late 1800s, its native salmon have returned in sizable numbers, reflecting the new cleanliness of a river that was once one of Britain's filthiest.The Clyde River Foundation surveyed fish populations last autumn at 69 sites in the Clyde and its tributaries, and found salmon in seven of the nine major tributaries.The migratory fish, which vanished from the Clyde around 1880 after a long decline, first reappeared in the 1980s, but last year's survey was the first to show they've come back in healthy numbers.Although commercial salmon fishing was never widespread on the Clyde, the fish's return is symbolically important for Glasgow, where salmon were once so important to the city's identity that two are pictured on its official coat of arms.The salmon's comeback is also a sign of big improvements to water quality. Like sea trout, which have also reappeared in the Clyde system in recent years, salmon are very sensitive to environmental conditions and require cool, well-oxygenated* water to thrive.The decline of Glasgow's main industries helped boost the fortunes of a river that was essentially fishless for decades during the worst periods of pollution.The closure of factories that had poured toxins* and other pollutants into the river boosted water quality significantly. Environmental regulators also lightened dumping rules, and modern sewage processing plants helped eliminate some of the foul* smells that once tainted* the air.With worries rising about the environmental impact of enormous fish farms elsewhere in Scotland and severely depleted fish stocks in the North Sea and North Atlantic, the Clyde comeback is a rare bit of good news for Scotland's fish lovers.Since the area that is now Glasgow was first settled around the year 550, the Clyde has been central to its history.The river's depth and navigability helped make Glasgow an important center for importing tobacco, sugar and cotton from the Americas starting in the 1600s. Later, during the IndustrialRevolution that began in the late 1700s, Glasgow became a center of British shipbuilding and one of the country's great manufacturing centers.The mills and factories that lined the Clyde made steel, textiles and chemicals, tanned leather and even produced candy and brewed alcohol.When the factories began to close in the second half of the 20th century, working-class Glasgow, Scotland's largest city, gained a reputation for social deprivation* and rough streets. More recently, its art museums and nightlife have helped drive an economic comeback that has turned the city into a popular tourist destination.Exercise A Pre-listening QuestionRivers are important to humans because they supply fresh drinking water, serve as home for important fishes, and provide transportation routes.Exercise B Sentence DictationDirections: Listen to some sentences and write them down.

For most people in these countries, formally joining the West represents the fulfillment of lifelong dreams. Eastward expansion is not the only issue to be discussed at the Prague Summit. Many people believe the political and military alliance, created after World War II to provide a collective security system for the ten West European countries and the United States and Canada, lost its purpose with the collapse of the Soviet Union - for many years its only threat.NATO expansion and its post-Cold War role have been the subject of endless debate on both sides of the Atlantic, especially after the terrorist attacks on the United States.A possible war in Iraq is also high on the Prague agenda. Critics in the United States note few of the current candidates for membership have military forces that can contribute significantly to the new form of conflict. Some observers cite the importance of even minimal contributions, such as participating in NATO border defense, surveillance* or peace-keeping operations. Exercise ADirections: Listen to the news item and complete the summary.This news item is about the NATO eastward expansion and its military contribution.Exercise BDirections: Listen to the news again and complete the following passage.At the Prague Summit many people believe the political and military alliance, created after World War II to provide a collective security system for the ten West European countries and the United States and Canada, lost its purpose with the collapse of the Soviet Union - for many years its only threat.Another item on the Prague agenda is a possible war in Iraq. Critics in the United States note that the new comers have no military forces that can /contribute significantly to the new form of conflict. Some observers cite the importance of even minimal contributions, such as participating in NATO border defense. surveillance or peace-keeping operations.News Item2NATO SummitOne month and one day before the Prague summit, President Bush met with the NATO Secretary General George Robertson and praised the alliance. At the time, Mr. Robertson described the Prague meeting as "a transformational summit", perhaps the most important in the history of the alliance.It is a transformation that began with the end of the Cold War, and gained momentum with the September 11th terrorist attacks on the United States.Just days after hijacked planes rammed into the World Trade Center and the Pentagon, NATO voted to invoke its charter and help defend the United States. The Bush administration thanked the alliance, asked for NATO help with surveillance flights over the east coast, and then proceeded to launch a war on terrorism outside the structure of the alliance.At the Prague meeting -the first NATO summit since the terrorist attacks on America -the alliance will take up the creation of a rapid deployment force which could be deployed outside Europe. Members will be asked to commit units with specialty skills that can be used in unique situations such as forces trained in dealing with chemical weapons or the special challenges of fighting in rugged* mountains.Exercise ADirections: Listen to the news item and complete the summary.This news item is about NATO's Prague Summit and its help to the USA.Exercise BDirections: Listen to the news again and answer the following questions.One month and one day before the Prague summit, President Bush met with the NATO Secretary General.When meeting with President Bush, the NATO Secretary General described the Prague summit as "a transformational summit", perhaps the most important in the history of the alliance.

News Item3Putin-Bush SummitPresidents Bush and Putin ended their talks with a joint statement in which they said Iraq must comply with UN demands to disarm or face major consequences.They stressed Iraqi leader Saddam Hussein must comply fully and unconditionally with the latest Security Council disarmament resolution, and they expressed concern about the proliferation* of weapons of mass destruction.Russia backed the UN resolution as one of the five permanent members of the Security Council. But Moscow does not support the use of force against Iraq.At the end of their meeting in an 18th-century castle near the St. Petersburg airport, Mr. Putin said he still hopes diplomatic pressure will produce results. And he urged President Bush to continue to work through the UN.Their statement on Iraq bears a striking resemblance to the language approved by the 19 NATO member countries at the Prague summit. Mr. Bush told reporters that it is important to assure Russia that it has nothing to fear from NATO expansion.Exercise ADirections: Listen to the news item and complete the summary.This news item is about the talks between the US president and the Russian president.

TSection Four Supplementary ExercisesPart 1Feature ReportBush’s Arrival in EuropeAir Force One touched down on a cool, rainy summer's night at a military base outside London. Mr. Bush said nothing to reporters during the more than seven-hour flight from Washington, and he left the air base without making any remarks.But before he left the White House, the president said he will stand firm on his positions on global warming and missile defense. They are issues that have divided America and its European allies. And the prospects for a quick resolution are as gloomy as the skies that greeted his arrival on European soil.These are issues sure to be discussed at length on the sidelines of the Genoa* summit meeting. The leaders of the world's seven largest industrialized countries plus Russia have put the plight* of the world's poorest nations at the top of their formal agenda. But no one expects to avoid the controversiesGenerated by President Bush's opposition to the Kyoto* climate treaty, and his plan to develop a missile defense system. iIn an interview with foreign journalists prior to his departure for London, Mr. Bush talked about the dispute over the Kyoto protocol. He said some leaders have been more sympathetic to his view than others. And he said he will seek to reassure critics that the United States is seeking viable* alternatives to the agreement, which calls for mandatory* controls on emissions of certain gases, such as carbon dioxide.His talks Thursday with British Prime Minister Tony Blair could provide a clue of what lies ahead. The two will meet at Chequers, Mr. Blair's official residence in the British countryside. Aspokesman for the Prime Minister indicates on global warming and missile defense the two leaders may simply agree to disagree.It will be a serene* spot for a meeting. All indications at the reception awaiting the G-8 summit participants in Genoa will be quite the opposite.About a hundred thousand protestors are expected and elaborate security measures are in place in the Italian port city. President Bush says he can't quite understand what motivates the demonstrators. In his interview with foreign reporters, he said their aggressive protest tactics do more harm than good. He added their anti-trade stance* would lock people into* poverty. Exercise ADirections: Listen to the news report and complete the summary.This news report is about the attitudes of President Bush and the US government towards the issues of global warming and missile defense.Exercise BDirections: Listen to the news again and complete the following passage.Mr. Bush arrived in London for a short visit before the G-8 summit in Genoa.But before he left the White House, the president said he will stand firm on his positions on global warming and missile defense, the issues that have divided America and its European allies and are sure to be discussed at length at the Genoa summit meeting.The leaders of the world's seven largest industrialized countries plus Russia have put the plight of the world's poorest nations at the top of their formal agenda.

They go back to nature in 40 days.The biggest demand for corn plastics has been outside the United States, where packing components are developed for many products exported to America.Corn-based plates are about 5 percent more expensive than traditional plastic, and the cups can be 25 percent more costly.5) A billion pounds of PLA can be harvested annually within a decade, which would mean 10 percent of America’s corn supply would be into plastics and fiber.sCorn plastic are being developed by Cargill Dpw LLC at its plant outside Blair,where refined corn suger is converted into a substance called polyactide or PLA . . The sugar is fermented* and distilled* to extract the carbon, a basic building block for commercial-grade plastics and fibers. PLA, in pellets* the size of 0.46 centimeters in diameter, is being pressed into packaging for food, plastic wrap, foam and dinner ware. It is spun into fabrics at plants in North Carolina, Hong Kongand several cities in Japan, and marketed under the Ingeo* brand of clothing and blankets. Cargill Dow, a joint venture between privately held food giant Cargill Inc. and Dow Chemical Co., says Ingeo means "ingredients from the Earth".DuPont Co. is in the early stages of developing a similar product, but it still includes some petroleum. The company is part of a consortium* that received US$19 million from the US Department of Energy to develop a way to turn com stocks, stems and leaves into a polymer* from which plastic can be made.Perhaps the greatest appeal of com plastics is their green credentials. It takes about a month for plastic bags made from com to degrade in a compost. A similar oil-based plastic bag could take centuries to decompose.Coca~Cola Co. used 500,000 cups made from com plastics at the Winter Olympics in Salt Lake City last year. Instead of creating a large trash problem, used cups were simply composted and quickly turned into dirt."The product performed beautifully. They go back to nature in 40 days," said Frederic Scheer, president of Los Angeles-based Biocorp North America, which supplied the cups.The biggest demand for com plastics has been outside the United States, including China's Taiwan island, where packing components are developed for many products exported to America. Taiwan bans petroleum-based plastic shopping bags and disposable plastic tableware. Electronics giant Sony Corp was involved in the early development of com plastics and has wrapped its mini discs in a com-based film made by Cargill Dow for two years. Cargill Dow also reached an agreement with Taiwan-based Wei Mon Industry to distribute com-plastic packaging materials. IPER, one of Italy's largest supermarket chains, has been working with the natural-based packaging from Cargill Dow for nearly a year for film containers and heat-sealable film overlays. The com-based plastic is more costly now. Biocorp North America*'s com-based plates are about 5 percent more expensive than traditional plastic, and the cups can be 25 percent more costly. But Scheer said the price will decline as production goes up with demand - which he expects to see within five years. That could amount to a highly productive and new use of America's com supply, which is so abundant that it is widely converted into com-based sweeteners and animal feed.Cargill Dow believes a billion pounds of PLA can be harvested annually within a decade. That would mean 10 percent of America's com supply would be converted into plastics and fibers. Exercise A Pre-listening QuestionCom starch is used primarily as a thickener. Sweeteners generated in the com-refining process are used as sugar substitutes. Refined com oil is used as cooking oil and producers of margarine, salad dressings, shortening, mayonnaise and other foods. The second major refined corn product is ethanol, which is gaining increasing acceptance as a cleaner burning option for motor fuels. The latest development in this field is the making of corn-based bio-chemical products like corn plastic and fiber.Exercise B Sentence DictationDirections: Listen to some sentences and write them down. You will hear each sentence three times.Exercise C Detailed ListeningDirections: Listen to the passage and answer the following questions.Corn plastics are being developed by Cargill Dow LLC at its plant outside Blair.The substance is called polylactide or PLA."Ingeo" is a brand of plastic fabrics made from corn sugar and it means "ingredients from the Earth".It takes about a month for plastic bags made from corn to degrade in a compost. A similar oil-based plastic bag could take centuries to decompose.Coca-Cola Co. used 500,000 cups made from corn plastics at the Winter Olympics in Salt Lake City.Many corn-plastic products are mentioned, such as cups and plates, shopping bags, packing components and packaging materials, film containers and heat-sealable film overlays. Probably because the production is still low now and the price will decline as production goes up with demand - possibly within five years.Cargill Dow believes a billion pounds of PLA can be harvested annually within a decade. Exercise D After-listening DiscussionDirections: Listen to the passage again and discuss the following questions..Frederic Scheer said the price will decline as production goes up with demand - which he expects to see within five years. That could amount to a highly productive and new use of America's corn supply, which is so abundant that it is widely converted into corn-based sweeteners and animal feed.(Open)。

That’s the subject, by the way, of another new article on the 1999 World Almanac. The greenhouse effect, exactly what causes it, and what steps to be taken to, perhaps to alleviate global warmings. I’ve seen recently that 1998 is going to go dow n as the warmest year ever on record. And so that’s going to be a major issue of the nextcentury, and possible tremendous consequences of the global warmings, whether it is rising sea levels affecting the coastal areas; changes in climate zones affecting what crops can be grown, and in what regions. This is potentially a very significant trend to be watched.E.

Here is David Willis.The storm with winds of up to 75 miles an hour struck India’s southeast coast, flattening homes, destroying crops and cutting transport links. Eyewitnesses reported tidal waves more than 12 feet high. The storm was followed by torrential rains, which swept away roads and railway lines, and flooded low lying areas. More than 40 people are thought to have died when a ferry sank. But most of the deaths have been due to flooding, houses collapsing or electrocutions. More than 100,000 people have been evacuated from their homes and are taking shelter in relief camps. After surveying the flooded area by helicopter, the chief minister said it resembled aburial ground. He’s appealed to the federal government to treat the incident as a national calamity.

The worst of the heavy rains and thunderstorms that have been sweeping parts of Europe during the past week appears to be over. Exceptionally heavy rainfall brought flooding to many parts of Germany, Switzerland, Northern Italy and France and chaos to rail and road transport. Although most flights are expected to be back to normal by this time tomorrow, there are expected to be serious delays on the German and Italian motorways over the forthcoming holiday weekend and train services are unlikely to be normalized for several days. A government spokeswoman in France announced that the damage to homes and property is expected to be at least four thousand million francs. It is reported that at least five people havelost their lives. Experts agree that casualty figures are low because emergency warnings were issued on the day before the storms began. The federal government in Switzerland has urged motorists and rail travelers not to travel during the next few days and no international traffic will be allowed on the main north-south motorway routes across the country until next Tuesday.Part III.

In September, satellite pictures showed more than 20000 fires burning in the Amazon. Experts say most of these fires were set by farmers. The farmers were attempting to clear land to grow crops. The World Wildlife Fund says another serious problem is that too many trees in the Amazon rain forest are being cut down. The World Wildlife Fund says the fires show the need for urgent international action to protect the world's rain forests. The group warns that without such action some forests could be lost forever.2. Environmental issues swell to the full in Berlin this week, for the UN spongsored conference on global warming and climate change is the first such meeting since the Rio summit three years ago. With scientists and governments now generally ready to accept that the earth climate is being affected by emissions of CO2 and other greenhouse gases, over a hundred countries are sending delegations. But how much progress has been made implementing the greenhouse gas reduction target agreed on at Rio? Simon Dary reports...Part II The Earth at risk (I)A.I (Interviewer): Brian Cowles is the producer of a new series of documentaries called "The Earth at Risk" which can be seen on Channel 4 later this month. Each program deals with a different continent, doesn't it, Brian?B (Brian Cowles): That's right. We went to America, both North and South and then we went over to Africa and South-East Asia.I: And what did you find in each of these continents?B: Starting with Africa, our film shows the impact of the population on the environment. Generally speaking, this has caused the Sahara Desert to expand. It's abit of a vicious circle we find. People cut down trees for firewood and their domestic animals eat all the available plants — and so consequently they have to move south as the Sahara Desert expands further south. I mean, soon the whole of Mali will become a desert. And in East Africa: here the grasslands are supporting too many animals and the result is, of course, there's no grass — nothing for the animals to eat. I: I see. And the next film deals with North America?B: That's right. In the USA, as you know, intensive agriculture requires a plentiful supply of rain for these crops to grow, I mean if there isn't enough rain the crops don't grow. And growing crops stabilize soil, without them the top soil just blows away. This is also true for any region that is intensely farmed — most of Europe, for example.I: And what did you find in South America?B: In South America (as in Central Africa and Southern Asia) tropical forests are being cut down at an alarming rate. This is done so that people can support themselves by growing food or to create ranches where cattle can be raised to be exported to Europe or America as tinned meat. The problem is that the soil is so poor that only a couple of harvests are possible before this very thin soil becomes exhausted. And it can't be fed with fertilizers like agricultural land in Europe.For example, in Brazil in 1982 an area of jungle the size of Britain and France combined was destroyed to make way for an iron ore mine. Huge numbers of trees are being cut down for exports as hardwood to Japan, Europe, USA to make things like luxury furniture. These forests can't be replaced —the forest soil is thin and unproductive and in just a few years, a jungle has become a waste land. Tropical forests contain rare plants (which we can use for medicines, for example) and animals —one animal or plant species becomes extinct every half hour. These forest trees also have worldwide effects. You know, they convert carbon dioxide into oxygen. The consequence of destroying forests is not only that the climate of that region changes (because there is less rainfall) but this change affects the whole world. I mean, over half the world's rain forest has been cut down this century.Part III The Earth at risk (II)A.I: So, Brian, would you agree that what we generally think of as natural disasters are in fact man-made?B: Yes, by and large. I mean, obviously not hurricanes or earthquakes, but take flooding, for example. Practically every year, the whole of Bangladesh is flooded and this is getting worse. You know, the cause is that forests have been cut down up in Nepal and India, I mean higher up-river in the Himalayas. Trees would hold rainfall in their roots, but if they've been cut down all the rain that falls in the monsoon season flows sraight into the river Ganges and floods the whole country. The reason for flooding in Sudan is the same — the forests higher up the Blue Nile in Ethiopia have been destroyed too.I: Well, this all sounds terribly depressing. Um ... What is to be done? I mean, cananything be done, in fact?B: Yes, of course it can. First, the national governments have to be forward-looking and consider the results of their policies in ten or twenty years, not just think as far ahead as the next election. Somehow, all the countries in the world have to work together on an international basis. Secondly, the population has to be controlled in some way: there are too many people trying to live off too little land. Thirdly, we don't need tropical hardwood to make our furniture —it's a luxury people in the West must do without. Softwoods are just as good, less expensive and can be produced on environment-friendly "tree farms", where trees are replaced at the same rate that they are cut down.I: And, presumably, education is important as well. People must be educated to realize the consequences of their actions?B: Yes, of course.I: Well, thank you, BrianB.I: So, Brian, would you agree that what we generally think of as ... er... as er ... natural disasters are in fact man-made?B: Yes, by and large ... er ...

We know this because average temperatures are the highest since scientists started measuring them 600 years ago. The increase is about0.2℃every year. This may seem very slight, but we know that slight changes in temperature can have a big effect on other things. Most scientists now believe this global warming is due to human activity.Jeff Jenkins is head of Britain's Climate Prediction Center. He explains how global warming can happen."Sunlight strikes the earth and warms it up. At the same time heat leaves the earth, but part of that is trapped by carbon dioxide and other gases in the earth's atmosphere. That has been happening ever since the earth was formed. But the fear is that increasing amounts of carbon dioxide produced by industrial processes and transport and so on will lead to a greater warming of the earth's surface. So that's the golbal warming that people are concerned about."People are most concerned about the use of fossil fuels. Fossil fuels are oil, coal, wood and so on. When these burn, they produce the gas carbon dioxide. Many scientists agree that an increase in the amount of carbon dioxide and some of the gases in the atmosphere will increase the amount of warming. Computers are being used to predict what this may mean. They showed that there could be great changes in rainfall and the rise in the sea level as ice caps in the north and south poles melt. This could have a serious effect on agriculture according to Prof. Martin Perry of University College in London. He says it could become more difficult to grow food in the tropics at lower latitudes nearer to the equator."The most clear pattern emerging is the possibility of reduced potential production in lower latitude regions, and most generally speaking, increased potential in higher latitude regions. Lower latitude regions are already warm, to put it extremely simply, and plants there are quite near their limits of heat and drought stress. An increase in temperature or reduction in moisture would place limits on crop growth." Woman: Global warming could reduce food production in lower latitude regions. Lower latitude regions are already warm. Global warming could put more stress on plans and place limits on crop growth.Food production is only one area that could be affected. There could also be health and social problems. Prof. Antony MacMichael of the London School of Hygiene and Tropical Medicine believes that some rural areas are already suffering. And the insects and bacteria could spread disease more easily."Already a number of rural populations around the world are suffering from the decline of agricultural systems. Climate change would add to this. And we would expect that it would accelerate the flood of environmental refugees around the world. But it includes not just the food production systems, but the patterns of distribution of insects and infective agents around the world. It includes likely effects on patterns of hear-related food poisoning, water contamination and diarrhea diseases, lots of things like this that would respond sensitively to changes in climate." Woman: Global warming could affect the distribution of insects. Global warming could change patterns of heat-related food poisoning.Many countries now agree that something must be done to reduce the danger of global warming. But a worldwide agreement on lowering the production of carbon dioxide has been difficult to reach. This is because many economies depend on fossilfuels like oil. Scientists believe it's now the politicians in every region of the world who need to take action.Part V Do you know…?Environment has taken rather a back seat politically since the Earth summit in Rio de Janeiro nearly 5 years ago. But the problems that meeting highlighted had not gone away. One environmental think tank —the International Food Policy Research Institute — has been looking at the future of water and its report reflects growing concern at the huge leap in usage over the past few years.In some parts of the world, water consumption has increased five fold. And the institute, known by its initials IFPRI, says shortages could soon become the trigger for conflict and a major barrier to feeding the world's growing population. Here's Richard Black of our Science Unit."It's often been said that water rather than oil will be the cause of warfare in the next century. According to the IFPRI report, the time when that happens might not be far away. The number of people affected by water shortage will increase ten fold over the next 30 years, it says, which could well lead to large scale conflicts.The main reason why water is becoming a scarce resource is agriculture, which now accounts for 70% of water consumption worldwide, 90% in some developing countries. Countless farmers have switched from growing indigenous crops for the home market to high yield export varieties, which inevitably need far more water. But the IFPRI report says that in some regions water shortage is now the single biggest impediment to feeding the population. Water scarcity also leads to water pollution. In the Indian State of West Bengal, for example, over extraction of water from bore holes has led to arsenic poisoning which is estimated to have affected two million people so far. But the IFPRI report calls for better water management worldwide including financial incentives to encourage conservation."That report by Richard Black of our Science Unit.Unit 2Part I Getting readyA.B.

As you can see, this is very valuable work and I wonder therefore if you'd like to make a donation?Part II Christmas bird countsJohn James Audubon was an American artist in the early0s, who illustrated birds in their natural habitats. The Society named after him was founded in the late0s by conservationists concerned with the decline of birds, which were being killed so their feathers could be used in the manufacture of women's hats.Sponsored by the National Audubon Society, more than 40 000 volunteers will be outside counting birds from today until January 3rd. Volunteers from all 50 states of the United States, every Canadian province, parts of Central and South America, Bermuda, the West Indies and Pacific islands have begun to count and record every individual bird and bird species observed during the two and one half week period of the count.Jeffrey LeBaron is the National Audubon Society's Christmas Bird Count editor. He says the count is the longest-running bird census in ornithology.This year, according to Mr. LeBaron, more than 1 600 separate bird counts have been scheduled. Some would have as few as 10 people taking part, others with hundreds. The logistics of the Christmas bird count, he adds, are simple."Each individual count is in a circle. It's a 15 mile diameter circle, um, around the exact center point. And it's always the exactly same area that's done every year, usually, even on the same weekend during the count period. And what the ideal would be, which is virtually impossible, is this census: every single individual bird within that circle on the count day."Mr. LeBaron says experienced bird counters can get a good idea of the total birdpopulations within the count circle based on the number of birds they actually see. The editor points out, however, that the counts are not only for experienced bird watchers."Anybody that is interested or concerned can become involved. Beginners will go out in a party with experienced individuals who know both the area and the birds in the area, in the field where more eyes and ears are better. And then anybody can point out a bird, and someone in the field will always be able to identify the bird."Part III Dolphin captivityA: A planned aquatic park in Denver is raising the ire of animal rights activists who object to a proposal to include a captive dolphin display. Although officials for Colorado's Ocean Journeys say they have yet to make a final decision on the issue, local and national activists have already instigated a "No Dolphins in Denver' campaign. As Colorado Public Radio's Peter Jones reports, the battle lines have been clearly drawn.P: Rick Troud, a former navy dolphin trainer based in Florida, is taking an active role in the "No Dolphins" campaign.R: Average age in the wild ranges anywhere in some of the studies between 30 and 40 years of age. In captivity, you can expect a dolphin to live maybe 5.13 years, and every 7 years in captivity, the dolphin population is dead.P: According to Troud, there are many reasons why dolphins can't live full lives in captivity.R: If you take a look at where the real dolphin is in the real ocean, you find the dolphin who swims 40 miles a day, is very family-oriented. These animals are separated from their mothers; that's a stress. You put them in a concrete tank where their sonar bounces off of walls, they can't swim in the same amount of time and direction that they can in the wild.P: Environmentalist and ocean explorer, Jean Michel Cousteau:J: There are some animals which reject captivity right away, and they're very suicidal. I've had one of those in my own arms for many days. The next morning when I came to take care of him, he was dead. And what he'd done was to swim as fast as he could from one end of the pool on ... to the other side and destroyed his head by hitting the wall. They have a very sophisticated brain. I don't think we have any rights to play with the lives of these animals. P: Cousteau's anti-captivity position is challenged by Dr. Deborah Duffield, a biology professor at Portland State College in Oregon. Her 1990 study compared captive dolphins to the wild population of Sarasota Bay, Florida. Among other findings, the study showed little if any difference in the average age of death. And Duffield says life is generally getting better for captive dolphins.D: The census data say that every time I do a census, I've got older and older animals in it as well as this normal age distribution that we've been looking at. So my feeling is that the trend in captivity has been that the group of animals that we're following are getting older, and if they continue to do that over thenext five years, they will then indeed be older than the wild population.P: There is also a debate over the educational benefits of keeping marine mammals in captivity. According to Duffield, captive dolphins play an important role in our basic understanding of the animals.D: I firmly believe that we cannot learn anything about organisms that we share this world with if we do not understand how they live in an environment, and what they do, and that watching them go by in the wild will not do it. I cannot tell what an animal needs, unless I know how it operates, how it breeds, what it needs metabolically, and I can't learn that from animals in the wild. P: But Troud says the dolphin displays are anti-educational because the animals' natural behavior patterns are altered by captivity.R: In the wild, you don't have dolphins who beat each other to death. There are no dolphins that I've ever seen stranded on the beach, who are suffering from fractured skulls, fractured ribs or fractured jaws, as is the case in captivity.P: The Ocean Journey board will take all factors into consideration before making a final decision on whether to include dolphins in the park. For Colorado Public Radio, I'm Peter Jones.Part IV More about the topic: Birds----A Source of Wealth Mr. LeBaron says there are about 9 300 different known species of birds. Larger numbers of them live in the warmer climates. For example, more than 300 different species have been counted in Panama, while far fewer species are native to colder climates. Aside from their esthetic value, Mr. LeBaron says birds are important to the environment because they can signal changes in it."Birds are one of the best indicators that we have of the quality of the environment within the given area. Whether it is a relatively local area, or even primarily on the worldwide bases, they are one of the first things to be altered. They are quite sensitive to a habitat alteration or to other threats. And often times when birds are disappearing out of the area, it just means there is a degradation of the quality of the habitat within that area which will adversely affect everything in there including humans."National Audubon Society editor Jeffrey LeBaron calls the world's bird populations a source of wealth that humans must protect."People get so much pleasure out of looking at birds and listening to birds. And if they start disappearing just the er, the quality of life, um, may be not physically, but the mental quality of life can be degraded quickly."Jeffrey LeBaron says that while the National Audubon Society's annual Christmas bird counts show a decline in some species, many types of birds are actually increasing their populations.Part V Do you know…?Scientists have cataloged more than one and one-half million of the species that existon Earth today. By some recent estimates, at least 20 times that many species inhabit the planet.Up to 100 species become extinct every day. Scientists estimate that the total number of species lost each year may climb to 40 000 by the year 2000, a rate far exceeding any in the last 65 million years.Around the world more than 3 500 protected areas exist in the form of parks, wildlife refuges and other reserves. These areas cover a total of about 2 million square miles (5 million square km, or 3% of our total land area).Today, more than 200 animal species in the United States are classified as endangered. More than 1 000 animal species are endangered worldwide.Little-noticed aquatic animals are in big trouble. In North America, a third of our fish species, two-thirds of our crayfish species and nearly three-quarters of the mussel species are in trouble.Unit 3Unit 3 El Nino?

You know I was born in Lausanne*, Switzerland; my father was Swiss-French Swiss and my mother was American, so, of course, we spoke both languages at home and I grew up bilingual. Then, of course, I learnt German at school - in Switzerland that's normal. And because I was already fluent in English, my second language at school was Italian. So I had a real head start*!Interviewer: So that's ... one, two, three, four - you had learnt four languages by the time you left school? How fluent were you?Suzanne: Urn, I was native speaker standard in French and English, but I'd become a bit rusty* in German and my Italian was only school standard. I decided the best option was to study in the UK, and I did Hispanic Studies at university, studying Spanish and Portuguese, with some Italian, and living in Manchester. Then I went to live in Brazil for two years, teaching English. Interviewer: So by this time you must have been fluent in six languages?Suzanne: Nearly. My Italian wasn't perfect, but I had a boyfriend from Uruguay* while I was there, so my Spanish also became pretty good!Interviewer: And then what did you do?Suzanne: When I was 25 I came back to Switzerland, went to an interpreters' school and then got a job in the United Nations when I was 28.Interviewer: And you've been there ever since?Suzanne: Not quite. In the first few months I met Jan, a Czech interpreter, who became my husband. We went to live in Prague in 1987 and that was where I learnt Czech.Interviewer: And the eighth language?Suzanne: Well, unfortunately the marriage didn't last; I was very upset and I decided to take a long break. I went to Japan on holiday, got a job and stayed for two years, which was when I learnt Japanese.Interviewer: That's amazing! And now you're back at the United Nations?Suzanne: Yes. Well, I never really left. I carried on doing work for them when I was in Prague -some in Prague, some in Austria and Switzerland, and I took a "sabbatical*" to work in Japan. They need people who can understand Japanese. But, yes, I've been back with them full-time for two years now.Interviewer: And your plans for the future?Suzanne: I'm going to learn more Oriental languages. It was such a challenge learning Japanese -it's so different from all the others. So I'll spend another two or three years here with the UN full-time, during which time I hope to get a substantial promotion, then I think I'll go back and learn Korean, or perhaps Chinese, and Thai - I'd love to learn Thai. And then, perhaps an Indian language. Whatever, I want to be fluent in another three or four languages before 45.ExerciseDirections: Listen to the dialogue and decide whether the following statements are true (T) or false (F).l.T 2.F 3.F 4.F 5.T 6.F 7.T 8.T 9. T 10. FPart 2 PassageThe Clyde RiverSalmon are very sensitive to environmental conditions and require cool, well-oxygenated water to thrive.The closure of factories that had poured toxins and other pollutants into the river boosted water quality significantly and modern sewage processing plants helped eliminate some of the foul smells.The river's depth and navigability helped make Glasgow an important center for importing tobacco, sugar and cotton from the Americas starting in the 1600s.The mills and factories that lined the Clyde made steel, textiles and chemicals, tanned leather and even produced candy and brewed alcohol.When the factories began to close in the second half of the 20th century, working-class Glasgow, Scotland's largest city, gained a reputation for social deprivation and rough streets.Running through one of Britain's biggest manufacturing centers, Glasgow, the Clyde River* was poisoned for more than a century by the fetid* byproducts of industry.The waterway bore the brunt of Glasgow's economic success during the Industrial Revolution and beyond, as pollution and chemicals destroyed its fish and wildlife populations and brewed smells whose memory still makes residents wince*. Now, with heavy industry gone and Glasgow reconceived as a center for culture and tourism, the Clyde is coming back to life.For the first time since the late 1800s, its native salmon have returned in sizable numbers, reflecting the new cleanliness of a river that was once one of Britain's filthiest.The Clyde River Foundation surveyed fish populations last autumn at 69 sites in the Clyde and its tributaries, and found salmon in seven of the nine major tributaries.The migratory fish, which vanished from the Clyde around 1880 after a long decline, first reappeared in the 1980s, but last year's survey was the first to show they've come back in healthy numbers.Although commercial salmon fishing was never widespread on the Clyde, the fish's return is symbolically important for Glasgow, where salmon were once so important to the city's identity that two are pictured on its official coat of arms.The salmon's comeback is also a sign of big improvements to water quality. Like sea trout, which have also reappeared in the Clyde system in recent years, salmon are very sensitive to environmental conditions and require cool, well-oxygenated* water to thrive.The decline of Glasgow's main industries helped boost the fortunes of a river that was essentially fishless for decades during the worst periods of pollution.The closure of factories that had poured toxins* and other pollutants into the river boosted water quality significantly. Environmental regulators also lightened dumping rules, and modern sewage processing plants helped eliminate some of the foul* smells that once tainted* the air.With worries rising about the environmental impact of enormous fish farms elsewhere in Scotland and severely depleted fish stocks in the North Sea and North Atlantic, the Clyde comeback is a rare bit of good news for Scotland's fish lovers.Since the area that is now Glasgow was first settled around the year 550, the Clyde has been central to its history.The river's depth and navigability helped make Glasgow an important center for importing tobacco, sugar and cotton from the Americas starting in the 1600s. Later, during the IndustrialRevolution that began in the late 1700s, Glasgow became a center of British shipbuilding and one of the country's great manufacturing centers.The mills and factories that lined the Clyde made steel, textiles and chemicals, tanned leather and even produced candy and brewed alcohol.When the factories began to close in the second half of the 20th century, working-class Glasgow, Scotland's largest city, gained a reputation for social deprivation* and rough streets. More recently, its art museums and nightlife have helped drive an economic comeback that has turned the city into a popular tourist destination.Exercise A Pre-listening QuestionRivers are important to humans because they supply fresh drinking water, serve as home for important fishes, and provide transportation routes.Exercise B Sentence DictationDirections: Listen to some sentences and write them down.

For most people in these countries, formally joining the West represents the fulfillment of lifelong dreams. Eastward expansion is not the only issue to be discussed at the Prague Summit. Many people believe the political and military alliance, created after World War II to provide a collective security system for the ten West European countries and the United States and Canada, lost its purpose with the collapse of the Soviet Union - for many years its only threat.NATO expansion and its post-Cold War role have been the subject of endless debate on both sides of the Atlantic, especially after the terrorist attacks on the United States.A possible war in Iraq is also high on the Prague agenda. Critics in the United States note few of the current candidates for membership have military forces that can contribute significantly to the new form of conflict. Some observers cite the importance of even minimal contributions, such as participating in NATO border defense, surveillance* or peace-keeping operations. Exercise ADirections: Listen to the news item and complete the summary.This news item is about the NATO eastward expansion and its military contribution.Exercise BDirections: Listen to the news again and complete the following passage.At the Prague Summit many people believe the political and military alliance, created after World War II to provide a collective security system for the ten West European countries and the United States and Canada, lost its purpose with the collapse of the Soviet Union - for many years its only threat.Another item on the Prague agenda is a possible war in Iraq.

Some observers cite the importance of even minimal contributions, such as participating in NATO border defense. surveillance or peace-keeping operations.News Item2NATO SummitOne month and one day before the Prague summit, President Bush met with the NATO Secretary General George Robertson and praised the alliance. At the time, Mr. Robertson described the Prague meeting as "a transformational summit", perhaps the most important in the history of the alliance.It is a transformation that began with the end of the Cold War, and gained momentum with the September 11th terrorist attacks on the United States.Just days after hijacked planes rammed into the World Trade Center and the Pentagon, NATO voted to invoke its charter and help defend the United States. The Bush administration thanked the alliance, asked for NATO help with surveillance flights over the east coast, and then proceeded to launch a war on terrorism outside the structure of the alliance.At the Prague meeting -the first NATO summit since the terrorist attacks on America -the alliance will take up the creation of a rapid deployment force which could be deployed outside Europe. Members will be asked to commit units with specialty skills that can be used in unique situations such as forces trained in dealing with chemical weapons or the special challenges of fighting in rugged* mountains.Exercise ADirections: Listen to the news item and complete the summary.This news item is about NATO's Prague Summit and its help to the USA.Exercise BDirections: Listen to the news again and answer the following questions.One month and one day before the Prague summit, President Bush met with the NATO Secretary General.When meeting with President Bush, the NATO Secretary General described the Prague summit as "a transformational summit", perhaps the most important in the history of the alliance.

News Item3Putin-Bush SummitPresidents Bush and Putin ended their talks with a joint statement in which they said Iraq must comply with UN demands to disarm or face major consequences.They stressed Iraqi leader Saddam Hussein must comply fully and unconditionally with the latest Security Council disarmament resolution, and they expressed concern about the proliferation* of weapons of mass destruction.Russia backed the UN resolution as one of the five permanent members of the Security Council. But Moscow does not support the use of force against Iraq.At the end of their meeting in an 18th-century castle near the St. Petersburg airport, Mr. Putin said he still hopes diplomatic pressure will produce results. And he urged President Bush to continue to work through the UN.Their statement on Iraq bears a striking resemblance to the language approved by the 19 NATO member countries at the Prague summit. Mr. Bush told reporters that it is important to assure Russia that it has nothing to fear from NATO expansion.Exercise ADirections: Listen to the news item and complete the summary.This news item is about the talks between the US president and the Russian president.

Mr. Bush said nothing to reporters during the more than seven-hour flight from Washington, and he left the air base without making any remarks.But before he left the White House, the president said he will stand firm on his positions on global warming and missile defense. They are issues that have divided America and its European allies. And the prospects for a quick resolution are as gloomy as the skies that greeted his arrival on European soil.These are issues sure to be discussed at length on the sidelines of the Genoa* summit meeting. The leaders of the world's seven largest industrialized countries plus Russia have put the plight* of the world's poorest nations at the top of their formal agenda. But no one expects to avoid the controversiesGenerated by President Bush's opposition to the Kyoto* climate treaty, and his plan to develop a missile defense system. iIn an interview with foreign journalists prior to his departure for London, Mr. Bush talked about the dispute over the Kyoto protocol. He said some leaders have been more sympathetic to his view than others. And he said he will seek to reassure critics that the United States is seeking viable* alternatives to the agreement, which calls for mandatory* controls on emissions of certain gases, such as carbon dioxide.His talks Thursday with British Prime Minister Tony Blair could provide a clue of what lies ahead. The two will meet at Chequers, Mr. Blair's official residence in the British countryside. Aspokesman for the Prime Minister indicates on global warming and missile defense the two leaders may simply agree to disagree.It will be a serene* spot for a meeting. All indications at the reception awaiting the G-8 summit participants in Genoa will be quite the opposite.About a hundred thousand protestors are expected and elaborate security measures are in place in the Italian port city. President Bush says he can't quite understand what motivates the demonstrators. In his interview with foreign reporters, he said their aggressive protest tactics do more harm than good. He added their anti-trade stance* would lock people into* poverty. Exercise ADirections: Listen to the news report and complete the summary.This news report is about the attitudes of President Bush and the US government towards the issues of global warming and missile defense.Exercise BDirections: Listen to the news again and complete the following passage.Mr. Bush arrived in London for a short visit before the G-8 summit in Genoa.But before he left the White House, the president said he will stand firm on his positions on global warming and missile defense, the issues that have divided America and its European allies and are sure to be discussed at length at the Genoa summit meeting.The leaders of the world's seven largest industrialized countries plus Russia have put the plight of the world's poorest nations at the top of their formal agenda.

They go back to nature in 40 days.The biggest demand for corn plastics has been outside the United States, where packing components are developed for many products exported to America.Corn-based plates are about 5 percent more expensive than traditional plastic, and the cups can be 25 percent more costly.5) A billion pounds of PLA can be harvested annually within a decade, which would mean 10 percent of America’s corn supply would be into plastics and fiber.sCorn plastic are being developed by Cargill Dpw LLC at its plant outside Blair,where refined corn suger is converted into a substance called polyactide or PLA . . The sugar is fermented* and distilled* to extract the carbon, a basic building block for commercial-grade plastics and fibers. PLA, in pellets* the size of 0.46 centimeters in diameter, is being pressed into packaging for food, plastic wrap, foam and dinner ware. It is spun into fabrics at plants in North Carolina, Hong Kongand several cities in Japan, and marketed under the Ingeo* brand of clothing and blankets. Cargill Dow, a joint venture between privately held food giant Cargill Inc. and Dow Chemical Co., says Ingeo means "ingredients from the Earth".DuPont Co. is in the early stages of developing a similar product, but it still includes some petroleum. The company is part of a consortium* that received US$19 million from the US Department of Energy to develop a way to turn com stocks, stems and leaves into a polymer* from which plastic can be made.Perhaps the greatest appeal of com plastics is their green credentials. It takes about a month for plastic bags made from com to degrade in a compost. A similar oil-based plastic bag could take centuries to decompose.Coca~Cola Co. used 500,000 cups made from com plastics at the Winter Olympics in Salt Lake City last year. Instead of creating a large trash problem, used cups were simply composted and quickly turned into dirt."The product performed beautifully. They go back to nature in 40 days," said Frederic Scheer, president of Los Angeles-based Biocorp North America, which supplied the cups.The biggest demand for com plastics has been outside the United States, including China's Taiwan island, where packing components are developed for many products exported to America. Taiwan bans petroleum-based plastic shopping bags and disposable plastic tableware. Electronics giant Sony Corp was involved in the early development of com plastics and has wrapped its mini discs in a com-based film made by Cargill Dow for two years. Cargill Dow also reached an agreement with Taiwan-based Wei Mon Industry to distribute com-plastic packaging materials. IPER, one of Italy's largest supermarket chains, has been working with the natural-based packaging from Cargill Dow for nearly a year for film containers and heat-sealable film overlays. The com-based plastic is more costly now. Biocorp North America*'s com-based plates are about 5 percent more expensive than traditional plastic, and the cups can be 25 percent more costly. But Scheer said the price will decline as production goes up with demand - which he expects to see within five years. That could amount to a highly productive and new use of America's com supply, which is so abundant that it is widely converted into com-based sweeteners and animal feed.Cargill Dow believes a billion pounds of PLA can be harvested annually within a decade. That would mean 10 percent of America's com supply would be converted into plastics and fibers. Exercise A Pre-listening QuestionCom starch is used primarily as a thickener. Sweeteners generated in the com-refining process are used as sugar substitutes. Refined com oil is used as cooking oil and producers of margarine, salad dressings, shortening, mayonnaise and other foods. The second major refined corn product is ethanol, which is gaining increasing acceptance as a cleaner burning option for motor fuels. The latest development in this field is the making of corn-based bio-chemical products like corn plastic and fiber.Exercise B Sentence DictationDirections: Listen to some sentences and write them down. You will hear each sentence three times.Exercise C Detailed ListeningDirections: Listen to the passage and answer the following questions.Corn plastics are being developed by Cargill Dow LLC at its plant outside Blair.The substance is called polylactide or PLA."Ingeo" is a brand of plastic fabrics made from corn sugar and it means "ingredients from the Earth".It takes about a month for plastic bags made from corn to degrade in a compost.

Probably because the production is still low now and the price will decline as production goes up with demand - possibly within five years.Cargill Dow believes a billion pounds of PLA can be harvested annually within a decade. Exercise D After-listening DiscussionDirections: Listen to the passage again and discuss the following questions..Frederic Scheer said the price will decline as production goes up with demand - which he expects to see within five years.

Almanac editorial director says the experts believe the next century will bring lots of changes.Warm, of course, that our climate is going to continue getting warmer. That’s the subject, by the way, of another new article on the 1999 World Almanac. The greenhouse effect, exactly what causes it, and what steps to be taken to, perhaps to alleviate global warmings. I’ve seen recently that 1998 is going to go down as the warmest year ever on record. And so that’s going to be a major issue of the next century, and possible tremendous consequences of the global warmings, whether it is rising sea levels affecting the coastal areas; changes in climate zones affecting what crops can be grown, and in what regions. This is potentially a very significant trend to be watched.E. Cyclone: North or south of equator / Typhoon:/ Hurricane: Eastern PacificMajor ocean storms in the northern part of the world usually develop in late summer or autumn over waters near the equator. They are known by several different names. Scientists call these storms cyclones when they happen just north or south of the equator in the Indian Ocean. In the western Pacific Ocean or the China Sea, these storms are called typhoons. In the eastern Pacific and Atlantic Ocean, they are called hurricanes.Part IIA. Outline 1.

Some regions become wetter than usual, others drier. The El Nino, which began in 1991 has lingered through this year. Although several years might have been expected to pass before the next one, an American-French satellite observing the oceans has found a sign that El Nino may come back quicker than expected.These kinds of things still happen. This is Brig Jacker, an oceanographer of the US Naval Research Laboratory in Mississippi.Every year is unpredictable. One year might be El Nino year, one year might not. Generally El Nino’s come in four year cycles. But there’s nothing to say that you can’t have two El Nino years in a row.El Nino’s begin with the decline of winds pulling cold water away from South America’s west coast to around the equator. This allows warm water in the western Pacific Ocean to expandeastward toward the America’s. At the same time, the clouds and rain over the warm water move eastward too. Radar aboard the American-French satellite detected the hint that such water movement began in early August and reached South America two months later. It saw a ripple called a “Calvin wave”moving slowly eastward. Such pulses sometimes give rise to El Nino conditions in the eastern equatorial Pacific.El Nino’s can change the weather around the world, but how much depends on its strength. A strong one in 1982 and 1983 has been linked to droughts in Australia and Indonesia, rains and flooding in South America, and unseasonably in 1991 has caused trouble. It has been associated with devastating floods in the US southeast last year and in the US Midwest this year. El Nino’s are hard on the South American fishing industry. The warm waters prevent nutrients rich cold water from rising to the surface, causing fish stocks to become depletive. Mr. Jacker said a new El Nino apparently would be mild but he is not betting on it yet.The US Naval oceanographer says predictions are difficult because the strength of El Nino depends on how winds affect the Calvin wave that has moved across the Pacific.Part III Lick ObservatoryB. location: an hour’s drive/ summit/Origin of the name: a wealthy businessmanSize: one meter diameter/ secondTime: 1888Present function: research/ an educational toolC. way of observation: human eyes; in the cold/ TV screenGains and losses: Romance/ the sky/ efficiency/ reality/ universeQuestions:1.Because lick Observatory is near “Silicon Valley”, a region of the states high-technology.2.Because Lick Observatory was built on his estate and he was buried at the base of thetelescope at this won request.3.By using the 19th century telescope, you have a feeling of romance with direct viewing withthe human eyes. By sing the modern devices, you lose that romance but gain the efficiency.That’s an exchange.It’s about an hour’s drive from the outskirts of San Jose, California, near the upper side of the state’s high-technology region known as Silicon V alley. As a visitor drives up the narrow winding road past red flowers, and eucalyptus trees, one of the first two seismographic stations in the world, it’s almost a surprise to glimpse the largest dome of Lick Observatory’s eight telescopes. Overlooking the world of computer age manufacturing are telescopes from the turn of the century which help shape our understanding of the universe.The huge dome, housing Lick Observatory’s giant, one meter wide reflecting telescope, is one of the few instruments in motion this morning on Mount Hamilton. At the 1260-meter summit of Mount Hamilton is a small village of 55 permanent residents, some of them students in a one-room school house. But most at the research complex are visiting astronomers catching their first hours of sleep in an old dormitory after a night’s work at the telescopes. Reminton Stone, director of operations at Lick Observatory has worked at the top of Mount Hamilton for three decades. Now a part of the University of California, Lick Observatory got its name from a welthy businessman who never studied astronomy as MR. Stone explains: “And he came to SanFrancisco, just before the gold rush and he made a huge amount of money on real estate. When he died, he specified that some portion of his estate should be used to build the largest and most powerful telescope yet made and which was a 36 inch at that time. And at his own request he is buried at the base of the telescope. So this s a memorial to himself.”The telescope with its ode-meter-diameter reflecting lens was the largest telescope in the world for seven years following its completion in 1888. and today, its’ still the second largest telescope of its kind. Although the one meter reflecting telescope is still used for some research, its hard to adapt today’s electronic instruments to the old historic telescope. Now, it is used mostly as an educational tool for teachers and the thousands of visitors who come each year. While the other telescopes at Lick Observatory are connected to electronic imagine devices that allow the astronomers to view celestial objects on television screens, the 19th century telescope allows direct viewing with the human eye. It’s one of the few giant telescopes in the world tht still requires some users to sit out in the cold under the dark sky and the dome. That brings a feeling of nostalgia to Reminton Stone.I really do miss being able to see the sky, and seeing these wonderful data appear in the computer screen is really nice, but it’s very divorced from the reality, from the universe. I miss a lot being in a dark place in these fields to look up to see the stars. We go out every now and then if we are working at…, we’re at the control room, we do go out to keep track of the skies, where the clouds are, and so forth, but one loses the romance and one gains greatly the efficiency. It’s a trade-off. Astronomer Reminton Stone, who manages the Lick Observatory complex at the top of mount Hamilton, California.Part IV. The national climatic Data Center.A.OutlineI.

Another publication has monthly reports from 1500 observation stationsaround the world.5.The center had more than 900,000 requests from government officials, business owners,weather researchers and the general public last year.More and more people need to know about the weather. Anyone wanting information about past weather conditions can turn to a center supported by the United States government.The National Climatic Data Center reportedly has the world’s largest active collection of weather information. The National Climatic Data Center or NCDC was formed in 1951. it was established as a record center for America’s Department of Commerce. Its headquarters is in the southern city of Asheville, North Carolina.The NCDC collects weather records gathered by a number of weather observers and theUntied States government agencies. The Department of Defense, the National Weather Service and the coastguard are among those providing weather information. The center also collects weather records from around the world. Some information held by the NCDC is only a few hours old. Other records are a lot older. For example, the office has written weather observations made by early American diplomat Benjamin Franklin and by the third President of the United States Thomas Jefferson.Today modern scientific equipment including satellites, radar and solar radiation systems help people learn about the weather. Information collected by airplanes and ships also is used. The NCDC organizes this information and helps prepare it for publication and other uses. The center assists in the production of written records, weather maps and pictures. The information also is shared by computer, microfilm and telephone. The NCDC produces several publications about earth environment. One has monthly and yearly records about weather conditions in about 270 American cities. Another publication has monthly reports from 1500 observation stations around the world. It also has information from about 800 upper air stations which measure weather conditions at all levels of the atmosphere. The National Climatic Data Center receives requests for information from all over the world. Last year the center reportedly had more than 900,000 requests from government officials, business owners, weather researchers and the general public.Part V Do you know…?Meaning: little girlTime: the western coast of South America / The Pacific coast of Peru and EcuadorTime: winter monthsDuration: one to two years.Evidence: the eastern Pacific oceanImpacts: those of EL Nino/ drier than normal and others wetter.Scientists say the weather event known as El Nino is ending. Scientific instruments have shown that the Pacific Ocean waters warmed by El Nino are becoming cooler. Many weather experts are expecting the change in ocean temperatures to lead to conditions known as La Nina. El Nino means the little boy in the Spanish language, La Nina means the little girl.La Nina develops when winds near the western coast of South America strengthen. This causes cold air to form near the Pacific coast of Peru and Ecuador. Unusually low water temperatures in the eastern Pacific Ocean are evidence of La Nina. Ocean surface temperatures there drop almost 4 degrees. La Nina is strongest during winter months in the northern part of the world. It usually lasts one to two years. La Nina’s effects can be just as severe as those of EL Nino.Recently weather experts met in Colorado to exchange their findings about La Nina. The National Center for Atmospheric Research organized the conference. The experts agreed that the colder Pacific Ocean waters might influence weather conditions around the world. La Nina could make some places drier than normal and others wetter. Some reports presented at the conference said Southeast Asia is likely to receive a lot of rain during the present la Nina, so could South America, Central America and Africa. The northwestern part of Canada and the United States could be wetter than normal. The studies found that the southern untied States could be warmer and drier and more severe storms are possible in the western Atlantic Ocean.。

In September, satellite pictures showed more than 20000 fires burning in the Amazon. Experts say most of these fires were set by farmers. The farmers were attempting to clear land to grow crops. The World Wildlife Fund says another serious problem is that too many trees in the Amazon rain forest are being cut down. The World Wildlife Fund says the fires show the need for urgent international action to protect the world's rain forests. The group warns that without such action some forests could be lost forever.2. Environmental issues swell to the full in Berlin this week, for the UN spongsored conference on global warming and climate change is the first such meeting since the Rio summit three years ago. With scientists and governments now generally ready to accept that the earth climate is being affected by emissions of CO2 and other greenhouse gases, over a hundred countries are sending delegations. But how much progress has been made implementing the greenhouse gas reduction target agreed on at Rio? Simon Dary reports...Part II The Earth at risk (I)A.I (Interviewer): Brian Cowles is the producer of a new series of documentaries called "The Earth at Risk" which can be seen on Channel 4 later this month. Each program deals with a different continent, doesn't it, Brian?B (Brian Cowles): That's right. We went to America, both North and South and then we went over to Africa and South-East Asia.I: And what did you find in each of these continents?B: Starting with Africa, our film shows the impact of the population on the environment. Generally speaking, this has caused the Sahara Desert to expand. It's abit of a vicious circle we find. People cut down trees for firewood and their domestic animals eat all the available plants — and so consequently they have to move south as the Sahara Desert expands further south. I mean, soon the whole of Mali will become a desert. And in East Africa: here the grasslands are supporting too many animals and the result is, of course, there's no grass — nothing for the animals to eat. I: I see. And the next film deals with North America?B: That's right. In the USA, as you know, intensive agriculture requires a plentiful supply of rain for these crops to grow, I mean if there isn't enough rain the crops don't grow. And growing crops stabilize soil, without them the top soil just blows away. This is also true for any region that is intensely farmed — most of Europe, for example.I: And what did you find in South America?B: In South America (as in Central Africa and Southern Asia) tropical forests are being cut down at an alarming rate. This is done so that people can support themselves by growing food or to create ranches where cattle can be raised to be exported to Europe or America as tinned meat. The problem is that the soil is so poor that only a couple of harvests are possible before this very thin soil becomes exhausted. And it can't be fed with fertilizers like agricultural land in Europe.For example, in Brazil in 1982 an area of jungle the size of Britain and France combined was destroyed to make way for an iron ore mine. Huge numbers of trees are being cut down for exports as hardwood to Japan, Europe, USA to make things like luxury furniture. These forests can't be replaced —the forest soil is thin and unproductive and in just a few years, a jungle has become a waste land. Tropical forests contain rare plants (which we can use for medicines, for example) and animals —one animal or plant species becomes extinct every half hour. These forest trees also have worldwide effects. You know, they convert carbon dioxide into oxygen. The consequence of destroying forests is not only that the climate of that region changes (because there is less rainfall) but this change affects the whole world. I mean, over half the world's rain forest has been cut down this century.Part III The Earth at risk (II)A.I: So, Brian, would you agree that what we generally think of as natural disasters are in fact man-made?B: Yes, by and large. I mean, obviously not hurricanes or earthquakes, but take flooding, for example. Practically every year, the whole of Bangladesh is flooded and this is getting worse. You know, the cause is that forests have been cut down up in Nepal and India, I mean higher up-river in the Himalayas. Trees would hold rainfall in their roots, but if they've been cut down all the rain that falls in the monsoon season flows sraight into the river Ganges and floods the whole country. The reason for flooding in Sudan is the same — the forests higher up the Blue Nile in Ethiopia have been destroyed too.I: Well, this all sounds terribly depressing. Um ... What is to be done? I mean, cananything be done, in fact?B: Yes, of course it can. First, the national governments have to be forward-looking and consider the results of their policies in ten or twenty years, not just think as far ahead as the next election. Somehow, all the countries in the world have to work together on an international basis. Secondly, the population has to be controlled in some way: there are too many people trying to live off too little land. Thirdly, we don't need tropical hardwood to make our furniture —it's a luxury people in the West must do without. Softwoods are just as good, less expensive and can be produced on environment-friendly "tree farms", where trees are replaced at the same rate that they are cut down.I: And, presumably, education is important as well. People must be educated to realize the consequences of their actions?B: Yes, of course.I: Well, thank you, BrianB.I: So, Brian, would you agree that what we generally think of as ... er... as er ... natural disasters are in fact man-made?B: Yes, by and large ... er ...

We know this because average temperatures are the highest since scientists started measuring them 600 years ago. The increase is about0.2℃every year. This may seem very slight, but we know that slight changes in temperature can have a big effect on other things. Most scientists now believe this global warming is due to human activity.Jeff Jenkins is head of Britain's Climate Prediction Center. He explains how global warming can happen."Sunlight strikes the earth and warms it up. At the same time heat leaves the earth, but part of that is trapped by carbon dioxide and other gases in the earth's atmosphere. That has been happening ever since the earth was formed. But the fear is that increasing amounts of carbon dioxide produced by industrial processes and transport and so on will lead to a greater warming of the earth's surface. So that's the golbal warming that people are concerned about."People are most concerned about the use of fossil fuels. Fossil fuels are oil, coal, wood and so on. When these burn, they produce the gas carbon dioxide. Many scientists agree that an increase in the amount of carbon dioxide and some of the gases in the atmosphere will increase the amount of warming. Computers are being used to predict what this may mean. They showed that there could be great changes in rainfall and the rise in the sea level as ice caps in the north and south poles melt. This could have a serious effect on agriculture according to Prof. Martin Perry of University College in London. He says it could become more difficult to grow food in the tropics at lower latitudes nearer to the equator."The most clear pattern emerging is the possibility of reduced potential production in lower latitude regions, and most generally speaking, increased potential in higher latitude regions. Lower latitude regions are already warm, to put it extremely simply, and plants there are quite near their limits of heat and drought stress. An increase in temperature or reduction in moisture would place limits on crop growth." Woman: Global warming could reduce food production in lower latitude regions. Lower latitude regions are already warm. Global warming could put more stress on plans and place limits on crop growth.Food production is only one area that could be affected. There could also be health and social problems. Prof. Antony MacMichael of the London School of Hygiene and Tropical Medicine believes that some rural areas are already suffering. And the insects and bacteria could spread disease more easily."Already a number of rural populations around the world are suffering from the decline of agricultural systems. Climate change would add to this. And we would expect that it would accelerate the flood of environmental refugees around the world. But it includes not just the food production systems, but the patterns of distribution of insects and infective agents around the world. It includes likely effects on patterns of hear-related food poisoning, water contamination and diarrhea diseases, lots of things like this that would respond sensitively to changes in climate." Woman: Global warming could affect the distribution of insects. Global warming could change patterns of heat-related food poisoning.Many countries now agree that something must be done to reduce the danger of global warming. But a worldwide agreement on lowering the production of carbon dioxide has been difficult to reach. This is because many economies depend on fossilfuels like oil. Scientists believe it's now the politicians in every region of the world who need to take action.Part V Do you know…?Environment has taken rather a back seat politically since the Earth summit in Rio de Janeiro nearly 5 years ago. But the problems that meeting highlighted had not gone away. One environmental think tank —the International Food Policy Research Institute — has been looking at the future of water and its report reflects growing concern at the huge leap in usage over the past few years.In some parts of the world, water consumption has increased five fold. And the institute, known by its initials IFPRI, says shortages could soon become the trigger for conflict and a major barrier to feeding the world's growing population. Here's Richard Black of our Science Unit."It's often been said that water rather than oil will be the cause of warfare in the next century. According to the IFPRI report, the time when that happens might not be far away. The number of people affected by water shortage will increase ten fold over the next 30 years, it says, which could well lead to large scale conflicts.The main reason why water is becoming a scarce resource is agriculture, which now accounts for 70% of water consumption worldwide, 90% in some developing countries. Countless farmers have switched from growing indigenous crops for the home market to high yield export varieties, which inevitably need far more water. But the IFPRI report says that in some regions water shortage is now the single biggest impediment to feeding the population. Water scarcity also leads to water pollution. In the Indian State of West Bengal, for example, over extraction of water from bore holes has led to arsenic poisoning which is estimated to have affected two million people so far. But the IFPRI report calls for better water management worldwide including financial incentives to encourage conservation."That report by Richard Black of our Science Unit.Unit 2Part I Getting readyA.B.

As you can see, this is very valuable work and I wonder therefore if you'd like to make a donation?Part II Christmas bird countsJohn James Audubon was an American artist in the early 1800s, who illustrated birds in their natural habitats. The Society named after him was founded in the late 1800s by conservationists concerned with the decline of birds, which were being killed so their feathers could be used in the manufacture of women's hats.Sponsored by the National Audubon Society, more than 40 000 volunteers will be outside counting birds from today until January 3rd. Volunteers from all 50 states of the United States, every Canadian province, parts of Central and South America, Bermuda, the West Indies and Pacific islands have begun to count and record every individual bird and bird species observed during the two and one half week period of the count.Jeffrey LeBaron is the National Audubon Society's Christmas Bird Count editor. He says the count is the longest-running bird census in ornithology.This year, according to Mr. LeBaron, more than 1 600 separate bird counts have been scheduled. Some would have as few as 10 people taking part, others with hundreds. The logistics of the Christmas bird count, he adds, are simple."Each individual count is in a circle. It's a 15 mile diameter circle, um, around the exact center point. And it's always the exactly same area that's done every year, usually, even on the same weekend during the count period. And what the ideal would be, which is virtually impossible, is this census: every single individual bird within that circle on the count day."Mr. LeBaron says experienced bird counters can get a good idea of the total birdpopulations within the count circle based on the number of birds they actually see. The editor points out, however, that the counts are not only for experienced bird watchers."Anybody that is interested or concerned can become involved. Beginners will go out in a party with experienced individuals who know both the area and the birds in the area, in the field where more eyes and ears are better. And then anybody can point out a bird, and someone in the field will always be able to identify the bird."Part III Dolphin captivityA: A planned aquatic park in Denver is raising the ire of animal rights activists who object to a proposal to include a captive dolphin display. Although officials for Colorado's Ocean Journeys say they have yet to make a final decision on the issue, local and national activists have already instigated a "No Dolphins in Denver' campaign. As Colorado Public Radio's Peter Jones reports, the battle lines have been clearly drawn.P: Rick Troud, a former navy dolphin trainer based in Florida, is taking an active role in the "No Dolphins" campaign.R: Average age in the wild ranges anywhere in some of the studies between 30 and 40 years of age. In captivity, you can expect a dolphin to live maybe 5.13 years, and every 7 years in captivity, the dolphin population is dead.P: According to Troud, there are many reasons why dolphins can't live full lives in captivity.R: If you take a look at where the real dolphin is in the real ocean, you find the dolphin who swims 40 miles a day, is very family-oriented. These animals are separated from their mothers; that's a stress. You put them in a concrete tank where their sonar bounces off of walls, they can't swim in the same amount of time and direction that they can in the wild.P: Environmentalist and ocean explorer, Jean Michel Cousteau:J: There are some animals which reject captivity right away, and they're very suicidal. I've had one of those in my own arms for many days. The next morning when I came to take care of him, he was dead. And what he'd done was to swim as fast as he could from one end of the pool on ... to the other side and destroyed his head by hitting the wall. They have a very sophisticated brain. I don't think we have any rights to play with the lives of these animals. P: Cousteau's anti-captivity position is challenged by Dr. Deborah Duffield, a biology professor at Portland State College in Oregon. Her 1990 study compared captive dolphins to the wild population of Sarasota Bay, Florida. Among other findings, the study showed little if any difference in the average age of death. And Duffield says life is generally getting better for captive dolphins.D: The census data say that every time I do a census, I've got older and older animals in it as well as this normal age distribution that we've been looking at. So my feeling is that the trend in captivity has been that the group of animals that we're following are getting older, and if they continue to do that over thenext five years, they will then indeed be older than the wild population.P: There is also a debate over the educational benefits of keeping marine mammals in captivity. According to Duffield, captive dolphins play an important role in our basic understanding of the animals.D: I firmly believe that we cannot learn anything about organisms that we share this world with if we do not understand how they live in an environment, and what they do, and that watching them go by in the wild will not do it. I cannot tell what an animal needs, unless I know how it operates, how it breeds, what it needs metabolically, and I can't learn that from animals in the wild. P: But Troud says the dolphin displays are anti-educational because the animals' natural behavior patterns are altered by captivity.R: In the wild, you don't have dolphins who beat each other to death. There are no dolphins that I've ever seen stranded on the beach, who are suffering from fractured skulls, fractured ribs or fractured jaws, as is the case in captivity.P: The Ocean Journey board will take all factors into consideration before making a final decision on whether to include dolphins in the park. For Colorado Public Radio, I'm Peter Jones.Part IV More about the topic: Birds----A Source of Wealth Mr. LeBaron says there are about 9 300 different known species of birds. Larger numbers of them live in the warmer climates. For example, more than 300 different species have been counted in Panama, while far fewer species are native to colder climates. Aside from their esthetic value, Mr. LeBaron says birds are important to the environment because they can signal changes in it."Birds are one of the best indicators that we have of the quality of the environment within the given area. Whether it is a relatively local area, or even primarily on the worldwide bases, they are one of the first things to be altered. They are quite sensitive to a habitat alteration or to other threats. And often times when birds are disappearing out of the area, it just means there is a degradation of the quality of the habitat within that area which will adversely affect everything in there including humans."National Audubon Society editor Jeffrey LeBaron calls the world's bird populations a source of wealth that humans must protect."People get so much pleasure out of looking at birds and listening to birds. And if they start disappearing just the er, the quality of life, um, may be not physically, but the mental quality of life can be degraded quickly."Jeffrey LeBaron says that while the National Audubon Society's annual Christmas bird counts show a decline in some species, many types of birds are actually increasing their populations.Part V Do you know…?Scientists have cataloged more than one and one-half million of the species that existon Earth today. By some recent estimates, at least 20 times that many species inhabit the planet.Up to 100 species become extinct every day. Scientists estimate that the total number of species lost each year may climb to 40 000 by the year 2000, a rate far exceeding any in the last 65 million years.Around the world more than 3 500 protected areas exist in the form of parks, wildlife refuges and other reserves. These areas cover a total of about 2 million square miles (5 million square km, or 3% of our total land area).Today, more than 200 animal species in the United States are classified as endangered. More than 1 000 animal species are endangered worldwide.Little-noticed aquatic animals are in big trouble. In North America, a third of our fish species, two-thirds of our crayfish species and nearly three-quarters of the mussel species are in trouble.Unit 3Unit 3 El Nino? La Nina?Part ID. warmer/ green house effect / sea levels/ climate zonesAs 1998 ends and people look forward to the last year of the century, the World Almanac spoke with experts about what comes next. Almanac editorial director says the experts believe the next century will bring lots of changes.Warm, of course, that our climate is going to continue getting warmer. That’s the subject, by the way, of another new article on the 1999 World Almanac. The greenhouse effect, exactly what causes it, and what steps to be taken to, perhaps to alleviate global warmings. I’ve seen recently that 1998 is going to go down as the warmest year ever on record. And so that’s going to be a major issue of the next century, and possible tremendous consequences of the global warmings, whether it is rising sea levels affecting the coastal areas; changes in climate zones affecting what crops can be grown, and in what regions. This is potentially a very significant trend to be watched.E. Cyclone: North or south of equator / Typhoon:/ Hurricane: Eastern Pacific Major ocean storms in the northern part of the world usually develop in late summer or autumn over waters near the equator. They are known by several different names. Scientists call these storms cyclones when they happen just north or south of the equator in the Indian Ocean. In the western Pacific Ocean or the China Sea, these storms are called typhoons. In the eastern Pacific and Atlantic Ocean, they are called hurricanes.Part IIA. Outline 1.

You know I was born in Lausanne*, Switzerland; my father was Swiss-French Swiss and my mother was American, so, of course, we spoke both languages at home and I grew up bilingual. Then, of course, I learnt German at school - in Switzerland that's normal. And because I was already fluent in English, my second language at school was Italian. So I had a real head start*!Interviewer: So that's ... one, two, three, four - you had learnt four languages by the time you left school? How fluent were you?Suzanne: Urn, I was native speaker standard in French and English, but I'd become a bit rusty* in German and my Italian was only school standard. I decided the best option was to study in the UK, and I did Hispanic Studies at university, studying Spanish and Portuguese, with some Italian, and living in Manchester. Then I went to live in Brazil for two years, teaching English.Interviewer: So by this time you must have been fluent in six languages?Suzanne: Nearly. My Italian wasn't perfect, but I had a boyfriend from Uruguay* while I was there, so my Spanish also became pretty good!Interviewer: And then what did you do?Suzanne: When I was 25 I came back to Switzerland, went to an interpreters' school and then got a job in the United Nations when I was 28.Interviewer: And you've been there ever since?Suzanne: Not quite. In the first few months I met Jan, a Czech interpreter, who became my husband. We went to live in Prague in 1987 and that was where I learnt Czech.Interviewer: And the eighth language?Suzanne: Well, unfortunately the marriage didn't last; I was very upset and I decided to take a long break. I went to Japan on holiday, got a job and stayed for two years, which was when I learnt Japanese.Interviewer: That's amazing! And now you're back at the United Nations?Suzanne: Yes. Well, I never really left. I carried on doing work for them when I was in Prague - some in Prague, some in Austria and Switzerland, and I took a "sabbatical*" to work in Japan. They need people who can understand Japanese. But, yes, I've been back with them full-time for two years now.Interviewer: And your plans for the future?Suzanne: I'm going to learn more Oriental languages. It was such a challenge learning Japanese - it's so different from all the others. So I'll spend another two or three years here with the UN full-time, during which time I hope to get a substantial promotion, then I think I'll go back and learn Korean, or perhaps Chinese, and Thai - I'd love to learn Thai. And then, perhaps an Indian language. Whatever, I want to be fluent in another three or four languages before 45.ExerciseDirections: Listen to the dialogue and decide whether the following statementsare true (T) or false (F).9. T 10.

Like sea trout, which have also reappeared in the Clyde system in recent years, salmon are very sensitive to environmental conditions and require cool, well-oxygenated* water to thrive.The decline of Glasgow's main industries helped boost the fortunes of a river that was essentially fishless for decades during the worst periods of pollution.The closure of factories that had poured toxins* and other pollutants into the river boosted water quality significantly. Environmental regulators also lighteneddumping rules, and modern sewage processing plants helped eliminate some of the foul* smells that once tainted* the air.With worries rising about the environmental impact of enormous fish farms elsewhere in Scotland and severely depleted fish stocks in the North Sea and North Atlantic, the Clyde comeback is a rare bit of good news for Scotland's fish lovers.Since the area that is now Glasgow was first settled around the year 550, the Clyde has been central to its history.The river's depth and navigability helped make Glasgow an important center for importing tobacco, sugar and cotton from the Americas starting in the 1600s. Later, during the Industrial Revolution that began in the late 1700s, Glasgow became a center of British shipbuilding and one of the country's great manufacturing centers.The mills and factories that lined the Clyde made steel, textiles and chemicals, tanned leather and even produced candy and brewed alcohol.When the factories began to close in the second half of the 20th century, working-class Glasgow, Scotland's largest city, gained a reputation for social deprivation* and rough streets.

For most people in these countries, formally joining the West represents the fulfillment of lifelong dreams.Eastward expansion is not the only issue to be discussed at the Prague Summit. Many people believe the political and military alliance, created after World War II to provide a collective security system for the ten West European countries and the United States and Canada, lost its purpose with the collapse of the Soviet Union - for many years its only threat.NATO expansion and its post-Cold War role have been the subject of endless debate on both sides of the Atlantic, especially after the terrorist attacks on the United States.A possible war in Iraq is also high on the Prague agenda. Critics in the United States note few of the current candidates for membership have military forces that can contribute significantly to the new form of conflict. Some observers cite the importance of even minimal contributions, such as participating in NATO border defense, surveillance* or peace-keeping operations.Exercise ADirections: Listen to the news item and complete the summary.This news item is about the NATO eastward expansion and its military contribution.Exercise BDirections: Listen to the news again and complete the following passage.At the Prague Summit many people believe the political and military alliance, created after World War II to provide a collective security system for the ten West European countries and the United States and Canada, lost its purpose with the collapse of the Soviet Union - for many years its only threat.Another item on the Prague agenda is a possible war in Iraq. Critics in the United States note that the new comers have no military forces that can /contribute significantly to the new form of conflict. Some observers cite the importance of even minimal contributions, such as participating in NATO border defense. surveillance or peace-keeping operations.News Item2NATO SummitOne month and one day before the Prague summit, President Bush met with the NATO Secretary General George Robertson and praised the alliance. At the time, Mr. Robertson described the Prague meeting as "a transformational summit", perhaps the most important in the history of the alliance.It is a transformation that began with the end of the Cold War, and gained momentum with the September 11th terrorist attacks on the United States.Just days after hijacked planes rammed into the World Trade Center and the Pentagon, NATO voted to invoke its charter and help defend the United States. The Bush administration thanked the alliance, asked for NATO help with surveillance flights over the east coast, and then proceeded to launch a war on terrorism outside the structure of the alliance.At the Prague meeting - the first NATO summit since the terrorist attacks on America - the alliance will take up the creation of a rapid deployment force which could be deployed outside Europe. Members will be asked to commit units with specialty skills that can be used in unique situations such as forces trained in dealing with chemical weapons or the special challenges of fighting in rugged* mountains.Exercise ADirections: Listen to the news item and complete the summary.This news item is about NATO's Prague Summit and its help to the USA.Exercise BDirections: Listen to the news again and answer the following questions.One month and one day before the Prague summit, President Bush met with the NATO Secretary General.When meeting with President Bush, the NATO Secretary General described the Prague summit as "a transformational summit", perhaps the most important in the history of the alliance.Because just days after September 11 th terrorist attacks, NATO voted to invoke its charter and help defend the United States.They are the skills that can deal with chemical weapons or fight in rugged mountains and the like.News Item3Putin-Bush SummitPresidents Bush and Putin ended their talks with a joint statement in which they said Iraq must comply with UN demands to disarm or face major consequences.They stressed Iraqi leader Saddam Hussein must comply fully and unconditionally with the latest Security Council disarmament resolution, and they expressed concern about the proliferation* of weapons of mass destruction.Russia backed the UN resolution as one of the five permanent members of the Security Council.But Moscow does not support the use of force against Iraq.At the end of their meeting in an 18th-century castle near the St. Petersburg airport, Mr. Putin said he still hopes diplomatic pressure will produce results. And he urged President Bush to continue to work through the UN.Their statement on Iraq bears a striking resemblance to the language approved by the 19 NATO member countries at the Prague summit.

Mr. Bush said nothing to reporters during the more than seven-hour flight from Washington, and he left the air base without making any remarks.But before he left the White House, the president said he will stand firm on his positions on global warming and missile defense. They are issues that have divided America and its European allies. And the prospects for a quick resolution are as gloomy as the skies that greeted his arrival on European soil.These are issues sure to be discussed at length on the sidelines of the Genoa* summit meeting. The leaders of the world's seven largest industrialized countries plus Russia have put the plight* of the world's poorest nations at the top of their formal agenda. But no one expects to avoid the controversiesGenerated by President Bush's opposition to the Kyoto* climate treaty, and his plan to develop a missile defense system. iIn an interview with foreign journalists prior to his departure for London, Mr. Bush talked about the dispute over the Kyoto protocol. He said some leaders have been more sympathetic to his view than others. And he said he will seek to reassure critics that the United States is seeking viable* alternatives to the agreement,which calls for mandatory* controls on emissions of certain gases, such as carbon dioxide.His talks Thursday with British Prime Minister Tony Blair could provide a clue of what lies ahead. The two will meet at Chequers, Mr. Blair's official residence in the British countryside. A spokesman for the Prime Minister indicates on global warming and missile defense the two leaders may simply agree to disagree.It will be a serene* spot for a meeting. All indications at the reception awaiting the G-8 summit participants in Genoa will be quite the opposite.About a hundred thousand protestors are expected and elaborate security measures are in place in the Italian port city. President Bush says he can't quite understand what motivates the demonstrators. In his interview with foreign reporters, he said their aggressive protest tactics do more harm than good. He added their anti-trade stance* would lock people into* poverty.Exercise ADirections: Listen to the news report and complete the summary.This news report is about the attitudes of President Bush and the US government towards the issues of global warming and missile defense.Exercise BDirections: Listen to the news again and complete the following passage.Mr. Bush arrived in London for a short visit before the G-8 summit in Genoa.But before he left the White House, the president said he will stand firm on his positions on global warming and missile defense, the issues that have dividedAmerica and its European allies and are sure to be discussed at length at the Genoa summit meeting.The leaders of the world's seven largest industrialized countries plus Russia have put the plight of the world's poorest nations at the top of their formal agenda.

They go back to nature in 40 days.The biggest demand for corn plastics has been outside the United States, where packing components are developed for many products exported to America.Corn-based plates are about 5 percent more expensive than traditional plastic, and the cups can be 25 percent more costly.5) A billion pounds of PLA can be harvested annually within a decade, which would mean 10 percent of America’s corn supply would be into pl astics and Corn plastic are being developed by Cargill Dpw LLC at its plant outside Blair,where refined corn suger is converted into a substance called polyactide or PLA . . The sugar is fermented* and distilled* to extract the carbon, a basic building block for commercial-grade plastics and fibers.PLA, in pellets* the size of centimeters in diameter, is being pressed into packaging for food, plastic wrap, foam and dinner ware. It is spun into fabrics at plants in North Carolina, Hong Kong and several cities in Japan, and marketed under the Ingeo* brand of clothing and blankets. Cargill Dow, a joint venture between privately held food giant Cargill Inc. and Dow Chemical Co., says Ingeo means "ingredients from the Earth".DuPont Co. is in the early stages of developing a similar product, but it still includes some petroleum. The company is part of a consortium* that received US$19 million from the US Department of Energy to develop a way to turn com stocks, stems and leaves into a polymer* from which plastic can be made.Perhaps the greatest appeal of com plastics is their green credentials. It takes about a month for plastic bags made from com to degrade in a compost. A similar oil-based plastic bag could take centuries to decompose.Coca~Cola Co. used 500,000 cups made from com plastics at the Winter Olympics in Salt Lake City last year. Instead of creating a large trash problem, used cups were simply composted and quickly turned into dirt."The product performed beautifully. They go back to nature in 40 days," said Frederic Scheer, president of Los Angeles-based Biocorp North America, which supplied the cups.The biggest demand for com plastics has been outside the United States, including China's T aiwan island, where packing components are developed for many products exported to America. Taiwan bans petroleum-based plastic shopping bags and disposable plastic tableware. Electronics giant Sony Corp was involved in the early development of com plastics and has wrapped its mini discs in a com-based film made by Cargill Dow for two years. Cargill Dow also reached an agreement with Taiwan-based Wei Mon Industry to distribute com-plastic packaging materials.IPER, one of Italy's largest supermarket chains, has been working with the natural-based packaging from Cargill Dow for nearly a year for film containers and heat-sealable film overlays.The com-based plastic is more costly now. Biocorp North America*'s com-based plates are about 5 percent more expensive than traditional plastic, and the cups can be 25 percent more costly. But Scheer said the price will decline as production goes up with demand - which he expects to see within five years. That could amount to a highly productive and new use of America's com supply, which is so abundant that it is widely converted into com-based sweeteners and animal feed.Cargill Dow believes a billion pounds of PLA can be harvested annually within adecade. That would mean 10 percent of America's com supply would beconverted into plastics and fibers.Exercise A Pre-listening QuestionCom starch is used primarily as a thickener. Sweeteners generated in the com-refining process are used as sugar substitutes. Refined com oil is used as cooking oil and producers of margarine, salad dressings, shortening, mayonnaise and other foods. The second major refined corn product is ethanol, which is gaining increasing acceptance as a cleaner burning option for motor fuels. The latest development in this field is the making of corn-based bio-chemical products like corn plastic and fiber.Exercise B Sentence DictationDirections: Listen to some sentences and write them down. You will hear each sentence three times.Exercise C Detailed ListeningDirections: Listen to the passage and answer the following questions.Corn plastics are being developed by Cargill Dow LLC at its plant outside Blair.The substance is called polylactide or PLA."Ingeo" is a brand of plastic fabrics made from corn sugar and it means "ingredients from the Earth".It takes about a month for plastic bags made from corn to degrade in a compost.

For most people in these countries, formally joining the West represents the fulfillment of lifelong dreams. Eastward expansion is not the only issue to be discussed at the Prague Summit. Many people believe the political and military alliance, created after World War II to provide a collective security system for the ten West European countries and the United States and Canada, lost its purpose with the collapse of the Soviet Union - for many years its only threat.NATO expansion and its post-Cold War role have been the subject of endless debate on both sides of the Atlantic, especially after the terrorist attacks on the United States.A possible war in Iraq is also high on the Prague agenda. Critics in the United States note few of the current candidates for membership have military forces that can contribute significantly to the new form of conflict. Some observers cite the importance of even minimal contributions, such as participating in NATO border defense, surveillance* or peace-keeping operations.

Some observers cite the importance of even minimal contributions, such as participating in NATO border defense. surveillance or peace-keeping operations.News Item2NATO SummitOne month and one day before the Prague summit, President Bush met with the NATO Secretary General George Robertson and praised the alliance. At the time, Mr. Robertson described the Prague meeting as "a transformational summit", perhaps the most important in the history of the alliance.It is a transformation that began with the end of the Cold War, and gained momentum with the September 11th terrorist attacks on the United States.Just days after hijacked planes rammed into the World Trade Center and the Pentagon, NATO voted to invoke its charter and help defend the United States. The Bush administration thanked the alliance, asked for NATO help with surveillance flights over the east coast, and then proceeded to launch a war on terrorism outside the structure of the alliance.At the Prague meeting -the first NATO summit since the terrorist attacks on America -the alliance will take up the creation of a rapid deployment force which could be deployed outside Europe. Members will be asked to commit units with specialty skills that can be used in unique situations such as forces trained in dealing with chemical weapons or the special challenges of fighting in rugged* mountains.Exercise ADirections: Listen to the news item and complete the summary.This news item is about NATO's Prague Summit and its help to the USA.Exercise BDirections: Listen to the news again and answer the following questions.One month and one day before the Prague summit, President Bush met with the NATO Secretary General.When meeting with President Bush, the NATO Secretary General described the Prague summit as "a transformational summit", perhaps the most important in the history of the alliance.

News Item3Putin-Bush SummitPresidents Bush and Putin ended their talks with a joint statement in which they said Iraq must comply with UN demands to disarm or face major consequences.They stressed Iraqi leader Saddam Hussein must comply fully and unconditionally with the latest Security Council disarmament resolution, and they expressed concern about the proliferation* of weapons of mass destruction.Russia backed the UN resolution as one of the five permanent members of the Security Council. But Moscow does not support the use of force against Iraq.At the end of their meeting in an 18th-century castle near the St. Petersburg airport, Mr. Putin said he still hopes diplomatic pressure will produce results. And he urged President Bush to continue to work through the UN.Their statement on Iraq bears a striking resemblance to the language approved by the 19 NATO member countries at the Prague summit. Mr. Bush told reporters that it is important to assure Russia that it has nothing to fear from NATO expansion.Exercise ADirections: Listen to the news item and complete the summary.This news item is about the talks between the US president and the Russian president.

TSection Four Supplementary ExercisesPart 1Feature ReportBush’s Arrival in EuropeAir Force One touched down on a cool, rainy summer's night at a military base outside London. Mr. Bush said nothing to reporters during the more than seven-hour flight from Washington, and he left the air base without making any remarks.But before he left the White House, the president said he will stand firm on his positions on global warming and missile defense. They are issues that have divided America and its European allies. And the prospects for a quick resolution are as gloomy as the skies that greeted his arrival on European soil.These are issues sure to be discussed at length on the sidelines of the Genoa* summit meeting. The leaders of the world's seven largest industrialized countries plus Russia have put the plight* of the world's poorest nations at the top of their formal agenda. But no one expects to avoid the controversiesGenerated by President Bush's opposition to the Kyoto* climate treaty, and his plan to develop a missile defense system. iIn an interview with foreign journalists prior to his departure for London, Mr. Bush talked about the dispute over the Kyoto protocol. He said some leaders have been more sympathetic to his view than others. And he said he will seek to reassure critics that the United States is seeking viable* alternatives to the agreement, which calls for mandatory* controls on emissions of certain gases, such as carbon dioxide.His talks Thursday with British Prime Minister Tony Blair could provide a clue of what lies ahead. The two will meet at Chequers, Mr. Blair's official residence in the British countryside. Aspokesman for the Prime Minister indicates on global warming and missile defense the two leaders may simply agree to disagree.It will be a serene* spot for a meeting. All indications at the reception awaiting the G-8 summit participants in Genoa will be quite the opposite.About a hundred thousand protestors are expected and elaborate security measures are in place in the Italian port city. President Bush says he can't quite understand what motivates the demonstrators. In his interview with foreign reporters, he said their aggressive protest tactics do more harm than good. He added their anti-trade stance* would lock people into* poverty.

They go back to nature in 40 days.The biggest demand for corn plastics has been outside the United States, where packing components are developed for many products exported to America.Corn-based plates are about 5 percent more expensive than traditional plastic, and the cups can be 25 percent more costly.5) A billion pounds of PLA can be harvested annually within a decade, which would mean 10 percent of America’s corn supply would be into plastics and fiber.sCorn plastic are being developed by Cargill Dpw LLC at its plant outside Blair,where refined corn suger is converted into a substance called polyactide or PLA . . The sugar is fermented* and distilled* to extract the carbon, a basic building block for commercial-grade plastics and fibers. PLA, in pellets* the size of 0.46 centimeters in diameter, is being pressed into packaging for food, plastic wrap, foam and dinner ware. It is spun into fabrics at plants in North Carolina, Hong Kongand several cities in Japan, and marketed under the Ingeo* brand of clothing and blankets. Cargill Dow, a joint venture between privately held food giant Cargill Inc. and Dow Chemical Co., says Ingeo means "ingredients from the Earth".DuPont Co. is in the early stages of developing a similar product, but it still includes some petroleum. The company is part of a consortium* that received US$19 million from the US Department of Energy to develop a way to turn com stocks, stems and leaves into a polymer* from which plastic can be made.Perhaps the greatest appeal of com plastics is their green credentials. It takes about a month for plastic bags made from com to degrade in a compost. A similar oil-based plastic bag could take centuries to decompose.Coca~Cola Co. used 500,000 cups made from com plastics at the Winter Olympics in Salt Lake City last year. Instead of creating a large trash problem, used cups were simply composted and quickly turned into dirt."The product performed beautifully. They go back to nature in 40 days," said Frederic Scheer, president of Los Angeles-based Biocorp North America, which supplied the cups.The biggest demand for com plastics has been outside the United States, including China's Taiwan island, where packing components are developed for many products exported to America. Taiwan bans petroleum-based plastic shopping bags and disposable plastic tableware. Electronics giant Sony Corp was involved in the early development of com plastics and has wrapped its mini discs in a com-based film made by Cargill Dow for two years. Cargill Dow also reached an agreement with Taiwan-based Wei Mon Industry to distribute com-plastic packaging materials. IPER, one of Italy's largest supermarket chains, has been working with the natural-based packaging from Cargill Dow for nearly a year for film containers and heat-sealable film overlays. The com-based plastic is more costly now. Biocorp North America*'s com-based plates are about 5 percent more expensive than traditional plastic, and the cups can be 25 percent more costly. But Scheer said the price will decline as production goes up with demand - which he expects to see within five years. That could amount to a highly productive and new use of America's com supply, which is so abundant that it is widely converted into com-based sweeteners and animal feed.Cargill Dow believes a billion pounds of PLA can be harvested annually within a decade. That would mean 10 percent of America's com supply would be converted into plastics and fibers. Exercise A Pre-listening QuestionCom starch is used primarily as a thickener. Sweeteners generated in the com-refining process are used as sugar substitutes. Refined com oil is used as cooking oil and producers of margarine, salad dressings, shortening, mayonnaise and other foods. The second major refined corn product is ethanol, which is gaining increasing acceptance as a cleaner burning option for motor fuels. The latest development in this field is the making of corn-based bio-chemical products like corn plastic and fiber.Exercise B Sentence DictationDirections: Listen to some sentences and write them down. You will hear each sentence three times.Exercise C Detailed ListeningDirections: Listen to the passage and answer the following questions.Corn plastics are being developed by Cargill Dow LLC at its plant outside Blair.The substance is called polylactide or PLA."Ingeo" is a brand of plastic fabrics made from corn sugar and it means "ingredients from the Earth".It takes about a month for plastic bags made from corn to degrade in a compost. A similar oil-based plastic bag could take centuries to decompose.Coca-Cola Co. used 500,000 cups made from corn plastics at the Winter Olympics in Salt Lake City.Many corn-plastic products are mentioned, such as cups and plates, shopping bags, packing components and packaging materials, film containers and heat-sealable film overlays. Probably because the production is still low now and the price will decline as production goes up with demand - possibly within five years.Cargill Dow believes a billion pounds of PLA can be harvested annually within a decade. Exercise D After-listening DiscussionDirections: Listen to the passage again and discuss the following questions..Frederic Scheer said the price will decline as production goes up with demand - which he expects to see within five years. That could amount to a highly productive and new use of America's corn supply, which is so abundant that it is widely converted into corn-based sweeteners and animal feed.(Open)。
