Further Listening and SpeakingListening Task:Task1: Problems with our educational system？Script:Hi, everybody. My topic today is "Problems with our educational system".I disagree on a lot of the ways that things have happened for a longtime in our educational system.？It seems that educators just want to give standardized tests,？which focus only on academic performance and neglect students' abilities and interest in other areas.？I think there are a lot of people who are very intelligent,but haven't had the opportunities they could have had if they had learned in a broader-minded educational system.？I feel that a lot of courses that students are required to take in high school are too academic, and, as a result,many kids have lost their interest in often fail to recognize various kinds of intelligence.？They simply exert a lot of pressure on students to be as well-rounded as possible.？I think being well-rounded isn't really possible.？And as a consequence, some students I believe to be intelligent can't get into good colleges if they,？you know, haven't scored well on the math section, even if they are brilliant writers.Another thing that disturbs me is that the so-called weak students are separated from the rest of the school.？Some kids are kept in a separate class if their grades are lower than others'.And they're very aware of their social position, you know.？I think it causes them to act in a way that is not really positive.？They're just acting in a way they are expected. Often their grades go from bad to worse. And that's pretty sad.I think that many of the kids in those classes are intelligent,？but they never actually realize their potential because of the way they are treated early on in their education.？Keys:？(1)standardized tests？(2)abilities and interest？(3)interest？(4)pressure？(5)well-rounded？(6)get into good colleges？(7)the rest of the school？(8)from bad to worseTask 2: The final examScriptAt a university, there were four sophomores taking a chemistry course.？They were doing so well on all the quizzes, midterms, labs, etc. that each had an "A" so far for the semester.These four friends were so confident that on the weekend before the final,？they decided to go up to the University of Virginia and party with some friends there.？They had a great time and didn't make it back to school until early Monday morning.Rather than taking the final then,？they decided to find their professor after the final and explain to him why they missed it.？They explained that they had planned to come back in time for the final exam, but,？unfortunately, they had a flat tire on the way back and didn't have a spare.As a result, they missed the final.The professor thought it over and then agreed they could make up the final the following day.？The guys were relieved and elated.？The next day, the professor placed them in separate rooms, handed each of them a paper, and told them to begin.They looked at the first problem, worth five points.？It was a simple question on a chemical reaction."Cool," they all thought at the same time, each one in his separate room, "this is going to be easy."？Each finished the problem and then turned the page.？On the second page was a question worth 95 points: "Which of the tires was flat"？Keys:？(1)course？(2)quizzes？(3)semester？(4)confident？(5)party？(6)make？(7)missed？(8)they had a flat tire on the way back and didn't have a spare？(9)placed them in separate rooms, handed each of them a paper？(10)On the second page was a question worth？Task3: Harvard University？ScriptHarvard University is the oldest institute of higher learning in the United States.？Founded 16 years after the arrival of the Pilgrims at Plymouth, the university has grown from nine students with a single master to the present enrollment of more than 21,000 students, including undergraduates and students in 10 graduate and professional schools.Over 14,000 people work at Harvard, including more than 2,100 faculty members.？Harvard has produced eight American presidents and many Nobel Prize winners.During its early years, Harvard offered a classic academic course based on the model of English universities,？but consistent with the prevailing Puritan philosophy.？Although many of its early graduates became ministers in Puritan churches throughout New England,？the university was never formally affiliated with a specific religious group.Under President Pusey, Harvard started what was then the largest fundraising campaign in the history of American higher education.？It was an program for the university.？The program increased faculty salaries, broadened student aid, created new professorships,and expanded Harvard's physical facilities.NeiI L. Rudenstine took office as Harvard's 26th president in 1991.？As part of an overall effort to achieve greater coordination among the university's schools and faculties,？Rudenstine encouraged academic planning and identified some of Harvard's main intellectual priorities.？He also stressed the importance of the university's excellence inundergraduate education,？the significance of keeping Harvard's doors open to students from families of different economic backgrounds,？and the task of adapting the research university to an era of both rapid information growth and serious fund shortage.？Keys: 3. CViewing and speaking:Task 1:University budget cutsScriptHost: Well, David Lammy, the University Minister, joins me from Westminster.Now thanks for joining us this lunchtime,？Mr. Lammy. How do these cuts... tie in with your much trumpeted commitment to increasing higher education？Interviewee: Well, I think it's important to remind viewers that we will spend well over 12 billion pounds on higher education this year and to also say that there will be more students at university next year than ever before in our history.？But what is important is that when they get to university, is that they have good facilities, good buildings,？that they have good contact with their lecturers and, for students from poorer backgrounds that they receive a grant.And you know 40 percent of students who are going to university are in receipt of some grants. So we have to plan...？Host:But there's going to be less money next year. That's the bottom line, isn't it？Interviewee: Er, we are asking universities to make a one percent cut in their teaching grant.？That's 51 million out of a total budget of over five billion.？Look, I think there are families across the country preparing for Christmas spending a bit less and they're,？you know, it's a lot more than one percent that they're, they're feeling.？So I think this is reasonable to ask universities if we are to ensure that we can continue to send more young people to university and we remain committed to that.？Host:And briefly, what about these two-year degrees This is a reduction in standards, isn't it？Interviewee:Well, we, we, we... It's important in this country that we remember that students aren't just the classic 18- to 21-year-old undergraduates.？We want mature students. We want more parttime students and over the last few years we've been growing the number of foundation degree,？two-year degrees that ensure that transition into high university and high level skills.？That's what we want to support and that's what we're indicating in the grant letter that we've sent to universities over the last few days.？Host:OK.

Um... more now than before.？Martha:What do you think is the most serious environmental problem in the world today？Ed: Today... I think damage to the ozone layer is a big problem, and another problem is pollution in big cities and things like that.？Martha: How do you learn about environmental problems？Ed: Um... through school. A lot of clubs promote environmental safety, and some TV programs, too. They talk about environmental safety and stuff like that.？Martha: Do you think students should learn more about the environment at school？Ed: I think so. So, as they grow older, they can be more aware of all the problems that are going on, and also to prevent more problems from occurring.？Martha: If you could create a new law to help the environment, what would it be？Ed: A new law for the environment Um... I'd probably say that when people throw away their cigarette butts, they have to throw them into the garbage bin, not just throw them everywhere because it's just littering and I hate that. So they should be fined if they throw them on the floor or on the ground.？Martha: That's a good idea. What do you personally do to help protect the environment？Ed: I'm so against littering. I never litter. If I see somebody litter, I get really angry. So I always throw my trash into the garbage bin.？Keys:？(1)nature？(2)environmental problem？(3)pollution？(4)promote？(5)aware of？(6)from occurring？(7)law？(8)throw away？(9)fined？(10)trash？Task 2:River pollutionScript:？If you see dead fish floating on the river or notice that the water is discolored and smelly,？you know the river has been polluted, and there are four main possible causes for it.First, fertilizer. If large amounts of fertilizer or farm waste drain into a river, the concentrations of nitrate and phosphate in the water increase use these substances to grow rapidly, turning the water green.？This massive growth of algae leads to pollution. When the algae die, they are broken down by the action of the bacteria, which quickly multiply, using up all the oxygen in the water and therefore causing the death of fish.Second, industrial waste. Factories sometimes discharge chemical waste into rivers. Examples of such pollutants include cyanide, lead, copper, and mercury. These substances may enter the water in such high concentrations that fish and other animals are killed immediately. Sometimes the pollutants enter the food chain and accumulate until they reach toxic levels, eventually killing fish and other animals.Third, oil pollution. If oil enters a slow-moving river, it forms a rainbow-colored film over the entire surface, preventing oxygen from entering the water.Fourth, warm water. Industry often uses water for cooling processes, sometimes discharging large quantities of warm water back into rivers.A higher temperature of the water lowers the level of dissolved oxygen and upsets the balance of life in the water.？Keys:Task3: Curbing carbon emissions？Script:？Although it is not an easy task, China is striving to fulfill the promise to cut its carbon dioxide emissions per unit of GDP by 40 to 45 percent in the next 10 years.Zhang Guobao, Director of the National Energy Administration, said, "The government puts great emphasis on seeking harmonious development between cities and the environment, and is readjusting the energy structure by giving priority to the development of clean and low-carbon energies, including hydroelectric, nuclear, wind, and solar power."Government authorities have closed small, coal-fired plants with a total capacity of million kilowatts in the past four years. This year's target of closing 10 million kilowatts of capacity will be achieved by August. "We have promised to the international community that 15 percent of our power will be generated from nonfossil sources by 2020," Director Zhang said. At present, non-fossil energy accounts for only percent.China is making efforts to increase the proportion of clean energy in its total energy consumption. Statistics show that China invested US$ billion in clean energy last year, exceeding the United States which investedUS$ billion. Thus, China has become the world leader in generating clean energy. Five years earlier, China's investment in clean energy was only US$ billion.However, China's carbon emission reduction target cannot be achieved easily. The shift to a low-carbon economy might be met at a cost to society. For instance, more than 400,000 people were laid off as a result of the shutdown of small coal-fired power plants in the past four years. Many studies indicate that the effort to curb greenhouse gas emissions may delay China's development, affect people's income, and lead to unemployment.？Keys:IV. Speaking OutMODEL1？MODEL2？MODEL3？V.

Further Listening and SpeakingListening Task:Task1: The environment and the development？Script:Li:Hi, Professor Wang.？I'm Li Lin, a correspondent for the university newspaper.？The staff and students here are getting more and more interested in the relationship between the environment and economic development.？What do you think is the most serious environmental problem at present What measures should we adopt to improve the environment and develop the economy at the same time？Wang: There are many environmental problems: air pollution, water pollution, desertification, overfishing, destruction of natural habitats, acid rain, overconsumption of wild animals and plants, etc. But lying at the center of all those problems, as I see it, is the contradiction between economic growth and the environment.Since the United Nations Earth Summit in 1992, growing number of people and governments have adopted the new idea of "sustainable development". This means today's economic growth should not wipe out the resources and options for future generations. Planning and development should ensure not only economic growth, but also social advancement and environmental health. In other words, some economic behavior must be restricted or controlled. Instilling principles of sustainable development into government planning, resource management and economic policy is the most important step China can take to solve its environmental problems. China has already taken some remarkable steps to reduce damage to the environment. For instance, following the huge floods of 1998, the government banned logging in the upper reaches of the Yangtze River in order to protect forests and reduce the risk of floods.Still, the basic contradiction between the environment and development persists. Much work is to be done before we can achieve the aim of a balance between economic growth and the environment.？Keys:(1)water pollution？(2)overconsumption？(3)economic growth？(4)resources？(5)social advancement？(6)restricted？(7)government planning？(8)economic policy？(9)remarkable steps？(10)balance？Task 2: Thick cloud of pollution covering southern Asia？ScriptA United Nations study says a thick cloud of pollution covering southern Asia threatens the lives of millions of people. Scientists say the pollution could increase lung disease and cause early death. The cloud is also damaging agriculture and affecting rainfall levels. It has affected many countries in southern Asia. The pollution cloud is three kilometers high. Scientists say it can move halfway around the world in a week.The cloud is the result of forest fires, the burning of agricultural waste, and huge increases in the burning of fuels by vehicles, industries, and power stations.Pollution from millions of bad cooking stoves has made the problem worse.？Many poor people burn fuels like wood and animal waste in such stoves. Scientists say the cloud of pollution appears to cool the land and oceans by blocking sunlight.？They say it reduces the amount of sunlight reaching the Earth's surface by as much as 15 percent.At the same time, heat inside the cloud warms the lower parts of the atmosphere.Harmful chemicals from the cloud are mixing with rainfall.？This acid rain damages crops and trees and threatens public health.？Scientists are concerned that the pollution will intensify during the next 30 years as the population of Asia increases to an estimated 5,000 million people.？Keys:Task3: Mountain regions face a number of dangersScriptMountain people around the world are in great danger of the negative effects of the worsening environment, according to a UN report.As global warming and deforestation accelerate and technology makes wilder places more accessible, environmental and social pressures on the world's remotest regions increase.The UN has found that many mountainous regions—inhabited by one out of five of the world's people—are barely recognizable when they are compared to what they were like 60 years ago.This is mostly because forests were cut to make way for cattle grazing and agriculture.The authors of the UN study expect 98 percent of the mountain areas to experience severe climate change by 2055.Biological losses are expected to be heavy.？The mountains of Europe, parts of California and the northwest Andes in South America are among the most threatened mountain areas in the world and should be given priority in conservation.The UN is anxious to raise awareness of the problems facing mountain areas because they are inhabited by some of the most vulnerable people.？These people could lose their culture and their livelihood with even the smallest shifts in climate.At the same time, many mountain regions are losing people. Thousands of villages in Europe are deserted most of the year.？In other areas like Nepal, people are drifting to the cities in search of work.？Keys:？(1)negative？(2)report？(3)warming？(4)pressures？(5)mountainous？(6)barely？(7)make way for？(8)expect 98 percent of the mountain areas to experience severe climate change by 2055？(9)The UN is anxious to raise awareness of the problems facing mountain areas？(10)Thousands of villages in Europe are deserted most of the year？Viewing and speaking:Task 1:Santa's home town in dangerScriptWeather experts may have found a new problem caused by global warming, one which many people will pay attention to: There are signs that Santa's home in the North may be in trouble because of warmer temperatures. The Finnish town of Rovaniemi on the Arctic Circle, which many Europeans say is the home of Santa Claus, has had its warmest winter in 40 years. As a result, there has been much less snow than usual—meaning no snowmen, no snowballs, and possibly not enough snow for Santa to ride his sleigh on.More important for local residents, it may mean fewer tourists, as well. Santa's wintry home town normally attracts thousands of visitors each year, and millions of dollars.Anne Pelttari-Bergman, the town's tourist director, worries that the town could be in trouble if snow levels do not return to normal.？She explains: "Snow is really important for us, of course, for Santa Claus, for Christmas tourism, and also for our winter tourism because winter is our best season. It is really important for us."Weather experts and town residents are hoping this warm winter is anone-time thing. Few people can imagine a holiday when even Santa does not have a white Christmas.？Keys:(1)signs？(2)warmer temperatures？(3)warmest？(4)snow？(5)attracts？(6)trouble？(7)normal？(8)season？(9)one-time？(10)white？Task 2:Talk after viewingScriptThe image of Santa Claus flying in a sleigh pulled by reindeer and leaving toys and gifts for every child is known worldwide, and Santa Claus has become the most beloved of Christmas symbols.But if the weather at Santa's home town were to become so warm that there was no more snow at Christmas, Santa Claus would lose his charm.？So snow is really important for Santa Claus, for his home town's Christmas tourism, and its winter tourism as winter is the best season in Santa's home town.？Unit 2 testPart IKeys:Part II(1)chemicals？(2)atmosphere？(3)particles？(4)trapped？(5)lasts？(6)human-based？(7)progressed？(8)Even in Ancient Rome people complained about smoke put into the atmosphere？(9)Air pollution can have serious consequences for the health of human beings？(10)Cities with large numbers of automobiles or those that use great quantities of coal often suffer most severely from air pollution problems？Part III？Part IV？Uint 3Culture makes me what I amTask 1:On the first dayCollectivism Individualism Individualism Collectivism？II.

Further Listening and SpeakingListening Task:Task1: Problems with our educational system？Script:To Americans, punctuality is a way of showing respect for other people's time.Being more than 10 minutes late to an appointment usually calls for an apology and maybe an explanation.People who are running late often call ahead to let others know of the delay.？Of course, the less formal the situation, the less important it is to be exactly on time.At informal get-togethers, for example, people often arrive as much as 30 minutes past the appointed time.But they usually don't try that at lifestyles show how much people respect the time of others.When people plan an event, they often set the time days or weeks in advance. Once the time is fixed, it takes almost an emergency to change it.？If people want to come to your house for a friendly visit, they will usually call first to make sure it is convenient.Only very close friends will just "drop in" unannounced.Also, people hesitate to call others late at night for fear they might already be in bed.？The time may vary, but most people think twice about calling after 10:00 .。
