Next Year Marks the EU's 50th Anniversary of the TreatyA. After a period of introversion and stunned self-disbelief， continental European governments will recover their enthusiasm for pan-Europeaninstitution-building in 2007. Whether the European public will welcome a return to what voters in two countries had rejected so short a time before is another matter.B. There are several reasons for Europe’s recovering self-confidence. For years European economies had been lagging dismally behind America (to say nothing of Asia)， but in 2006 the large continental economies had one of their best years for a decade， briefly outstripping America in terms of growth. Since politics often reacts to economic change with a lag， 2006’s improvement in economic growth will have its impact in 2007， though the recovery may be ebbing by then.C. The coming year also marks a particular point in a political cycle so regular that it almost seems to amount to a natural law. Every four or five years，European countries take a large stride towards further integration by signing a new treaty： the Maastricht treaty in 1992， the Treaty of Amsterdam in 1997， the Treaty of Nice in 2001. And in 2005 they were supposed to ratify a European constitution，laying the ground for yet more integration—until the calm rhythm was rudely shattered by French and Dutch voters. But the political impetus to sign something every four or five years has only been interrupted， not immobilised， by this setback.D. In 2007 the European Union marks the 50th anniversary of another treaty —the Treaty of Rome， its founding charter. Government leaders have already agreed to celebrate it ceremoniously， restating their commitment to “ever closer union”and the basic ideals of European unity. By itself， and in normal circumstances，the EU’s 50th-birthday greeting to itself would be fairly meaningless， a routine expression of European good fellowship. But it does not take a Machiavelli to spot that once governments have signed the declaration (and it seems unlikely anyone would be so uncollegiate as to veto it) they will already be halfway towards committing themselves to a new treaty. All that will be necessary will be to incorporate the 50th-anniversary declaration into a new treaty containing a number of institutionaland other reforms extracted from the failed attempt at constitution-building and —hey presto—a new quasi-constitution will be ready.E. According to the German government—which holds the EU’s agenda-setting presidency during the first half of 2007—there will be a new draft of a slimmed-down constitution ready by the middle of the year， perhaps to put to voters， perhaps not. There would then be a couple of years in which it will be discussed， approved by parliaments and， perhaps， put to voters if that is deemed unavoidable. Then，according to bureaucratic planners in Brussels and Berlin， blithely ignoring the possibility of public rejection， the whole thing will be signed， sealed and a new constitution delivered in 2009-10. Europe will be nicely back on schedule. Its four-to-five-year cycle of integration will have missed only one beat.F. The resurrection of the European constitution will be made more likely in 2007 because of what is happening in national capitals. The European Union is not really an autonomous organisation. If it functions， it is because the leaders of the big continental countries want it to， reckoning that an active European policy will help them get done what they want to do in their own countries.G. That did not happen in 2005-06. Defensive， cynical and self-destructive，the leaders of the three largest euro-zone countries—France， Italy and Germany —were stumbling towards their unlamented ends. They saw no reason to pursue any sort of European policy and the EU， as a result， barely functioned. But by the middle of 2007 all three will have gone， and this fact alone will transform the European political landscape.H. The upshot is that the politics of the three large continental countries，bureaucratic momentum and the economics of recovery will all be aligned to give a push towards integration in 2007. That does not mean the momentum will be irresistible or even popular. The British government， for one， will almost certainly not want to go with the flow， beginning yet another chapter in the long history of confrontation between Britain and the rest of Europe. More important，the voters will want a say. They rejected the constitution in 2005. It would befoolish to assume they will accept it after 2007 just as a result of an artful bit of tinkering.Questions 1-6 Do the following statemets reflect the claims of the writer in Reading Passage 1？Write your answer in Boxes 1-6 on your answer sheet.TRUE if the statemenht reflets the claims of the writerFALSE if the statement contradicts the claims of the writerNOT GIVEN if it is possbile to say what the writer thinks about this1.After years’ introspection and mistrust， continental European governments will resurrect their enthusiasm for more integration in 2007.2. The European consitution was officially approved in 2005 in spite of the oppositon of French and Dutch voters.3. The Treaty of Rome ， which is considered as the fundamental charter of the European Union， was signed in 1957.4.It is very unlikely that European countries will sign the declaration at the 50th anniversary of the Treaty of Rome.5.French government will hold the EU’s presidency and lay down the agenda during the first half of 2008.6.For a long time in hisotry， there has been confrontation between Britain and the rest of European countries.Questions 7-10 Complet the following sentencces.Choose NO MORE THAN THREE WORDS from Reading Passage 1 for each answer.Write your answer in Boxes 7-10 on your answer sheet.7.

Sleep medication linked to bizarre behaviourNew evidence has linked a commonly prescribed sleep medication with bizarre behaviours， including a case in which a woman painted her front door in her sleep.UK and Australian health agencies have released information about 240 cases of odd occurrences， including sleepwalking， amnesia and hallucinations among people taking the drug zolpidem.While doctors say that zolpidem can offer much-needed relief for people with sleep disorders， they caution that these newly reported cases should prompt a closer look at its possible side effects.Zolpidem， sold under the brand names Ambien， Stilnoct and Stilnox， is widely prescribed to treat insomnia and other disorders such as sleep apnea. Various forms of the drug， made by French pharmaceutical giant Sanofi-Aventis， were prescribed 674，500 times in 2005 in the UK.A newly published report from Australia’s Federal Health Department describes 104 cases of hallucinations and 62 cases of amnesia experienced by people taking zolpidem since marketing of the drug began there in 2000. The health department report also mentioned 16 cases of strangesleepwalking by people taking the medication.Midnight snackIn one of these sleepwalking cases a patient woke with a paintbrush in her hand after painting the front door to her house. Another case involved a woman who gained 23 kilograms over seven months while taking zolpidem. “It was only when she was discovered in front of an open refrigerator while asleep that the problem was resolved，” according to the report.The UK’s Medicines and Healthcare products Regulatory Agency， meanwhile， has recorded 68 cases of adverse reactions to zolpidem from 2001 to 2005.The newly reported cases in the UK and Australia add to a growing list of bizarre sleepwalking episodes linked to the drug in other countries， including reports of people sleep-driving while on the medication. In one case， a transatlantic flight had to be diverted after a passenger caused havoc after taking zolpidem.Hypnotic effectsThere is no biological pathway that has been proven to connect zolpidem with these behaviours. The drug is a benzodiazepine-like hypnotic that promotes deep sleep by interacting with brain receptors for a chemical called gamma-aminobutyric acid. While parts of the brain become less active during deep sleep， the body can still move， making sleepwalking a possibility.The product information for prescribers advises that psychiatric adverse effects， including hallucinations， sleepwalking and nightmares， are more likely in the elderly， and treatment should be stopped if they occur.Patient advocacy groups say they would like government health agencies and drug companies to take a closer look at the possible risks associated with sleep medicines. They stress that strange sleepwalking and sleep-driving behaviours can have risky consequences.“When people do something in which they’re not in full control it’s always a danger，” says Vera Sharav of the New York-based Alliance for Human Research Protection， a US network that advocates responsible and ethical medical research practices.Tried and tested“The more reports that come out about the potential side effects of the drug，the more research needs to be done to understand if these are real side effects，”says sleep researcher Kenneth Wright at the University of Colorado in Boulder， US.Millions of people have taken the drug without experiencing any strange side effects， points out Richard Millman at Brown Medical School， director of the SleepDisorders Center of Lifespan Hospitals in Providence， Rhode Island， US. He says that unlike older types of sleep medications， zolpidem does not carry as great a risk of addiction.And Wright notes that some of the reports of “sleep-driving” linked to zolpidem can be easily explained： some patients have wrongly taken the drug right before leaving work in hopes that the medicine will kick in by the time they reach home. Doctors stress that the medication should be taken just before going to bed.The US Food & Drug Administration says it is continuing to "actively investigate" and collect information about cases linking zolpidem to unusual side effects.The Ambien label currently lists strange behaviour as a “special concern” for people taking the drug. “It’s a possible rare adverse event，” says Sanofi-Aventis spokesperson Melissa Feltmann， adding that the strange sleepwalking behaviours “may not necessarily be caused by the drug” but instead result from an underlying disorder. She says that “the safety profile [of zolpidem] is well established”. The drug received approval in the US in 1993.Questions 1-6 Do the following statements agree with the information given in the reading passage？In boxes 1-6 on your answer sheet writeTRUE if the statement is true according to the passageFALSE if the statement is false according to the passageNOT GIVEN if the information is not given in the passage1. Ambien， Stilnoct and Stilnox are brand names of one same drug treating insomnia.2. The woman’s obesity problem wasn’t resolved until she stopped taking zolpidem.3. Zolpidem received approval in the UK in 2001.4. The bizarre behaviour of a passenger after taking zolpidem resulted in the diversion of a flight bound for the other side of the Atlantic.5. Zolpidem is the only sleep medication that doesn’t cause addiction.6. The sleep-driving occurrence resulted from the wrong use of zolpidem by an office worker.Question 7-9 Choose the appropriate letters A-D and Write them in boxes 7-9 on your answer sheet.7. How many cases of bizarre behaviours are described in an official report from Australia？A. 68B. 104C. 182D. 2408. Which of the following is NOT mentioned in the product information about zolpidem？A.

2014年雅思考试模拟试题及答案
Reading Passage 1 ECOTOURISM IN RUR A L MEXICO It’s not hard to advocate ecotourism——loosely defined as a form of travel that protects an area of the natural world while enabling the local people to preserve their culture and meet their daily needs.The hard part is making it work. Mexico，with many natural，still largely unspoiled areas and a land system based on community ownership，seems a likely ecotourism paradise.But its record of tourism development tells a different story. Now，thanks to the efforts of two consultants in Mexico City，the country may have figured out a way to benefit from the ecotourism market that is growing rapidly worldwide.Juan Carlos Ibarra and Antonio Suarez，co-owners of Balam Consultants，have succeeded where many other people have failed，helping local communities develop the ability to operate ecotourism ventures. Ibarra and Suarez began their current line of work in the early 1990s，helping the residents of the community of San Nicolas，outside Mexico City，develop and market recreational facilities that would attract tourists. Ibarra and Suarez spent more than 600 hours teaching people in the community business，marketing，and public relations skills.The result of this project was the San Nicolas Park，which now offers facilities for hiking and mountain biking on 2,304 hectares of land that otherwise would have been lost to illegal logging and urban sprawl.The project’s success is well regarded by professionals from around the world and is the most-visited ecotourism site in Mexico. The product of their efforts “shows what can be done.Its main value is that it enables those who will benefit or suffer most from ecotourism to take the decisions.” says Ron Mader of the website Americas Ecotourism.“The wonder of the work done by Ibarra and Suarez，”Mader says，“is that they make it look very simple.” An advantage for Mexico in the field of ecotourism development is land reforms implemented after the end of the Mexican Revolution in 1917.Property previously owned by the wealthy elite was redistributed to peasant communities in the form of communally owned village lands known as comunidades. Today，more than 23,000 communal groups Own and 1ive on 75 percent of Mexico’s land.Most of the country s splendid snowcapped volcanoes，lush jungles and white sand beaches are also communal property.This means that when tourists come to visit the country’s natural attractions，the local property owners should benefit. But some heavily promoted resorts，such as Cancun and Bahias de Huatulco，have been built On village lands that were taken by the government and sold to corporations. Although some local people are hired to work at these resorts，many do not have the appropriate skills or the knowledge of how these corporations work，said Ibarra. As a result，most of the well-paying jobs are filled by people from urban areas who have a better understanding of business Ibarra and Suarez are trying to stop this trend by working with the comunidades to develop community-based ecotourism projects.The two consultants have been conducting workshops on the subject in communities across the country. “In recent years，as the ecotourism boom reached Mexico，many companies started promoting trips to the wilderness areas of the country,” said Ibarra.“In the beginning，the owners of the lands in which ecotourism was being developed were not involved at all.Now，slowly but surely，rural populations have begun to perceive ecotourism as an economic alternative.” Commercially speaking，however，the residents of rural communities usually have no experience in running and marketing a business.Even if they have developed a well run project，visitors won’t come unless there is also effective marketing.After all，it is a business and they need to bring in customers. Ibarra and Suarez say teaching people in local communities how to run an ecotourism operation is easy.The hard part is helping rural inhabitants overcome a culturally ingrained notion that they are stupid and incapable of running such a business themselves. For every hour devoted to the instruction of business skills，the consultants spend four hours helping local residents build self-esteem and confidence.They are convinced that a project’s success depends on the involvement of the local landowners. Ron Mader views Ibarra and Suarez as pioneers in building successful ecotourism in Mexico.Their work.hesays，is“outstanding——not only because they have assisted in development of hiking and biking trails，but because they have demonstrated a profound respect for the communities Questions 1——5 Complete the summary below.Choose ONE ORTWO WORDS from the passage for each answer.Write your answers in boxes 1—5 on your answer sheet.

The number of local people working in tourism is decreasing. 9. Ibarra and Suarez want to encourage people who already understand business methods to work on ecotourism projects. 10. Recently，companies have been offering trips to see wild animals in Mexico. 11. People in the Mexican countryside often lack confidence in their own business skills. 12. The first thing that the consultants do in a community is to explain the benefits of ecotourism. 13 Ibarra and Suarez focus mainly on business skills training. 14 Ron Mader admires the attitude of Ibarra and Suarez to the rural 1andowners of Mexico. Reading Passage 2 High-tech Refrigeration 1 Refrigerators are the epitome of clunky technology: solid, reliable and just a little bit dull. They have not changed much over the past century, but then they have not needed to. They are based on a robust and effective idea--draw heat from the thing you want to cool by evaporating a liquid next to it, and then dump that heat by pumping the vapour elsewhere and condensing it. This method of pumping heat from one place to another served mankind well when refrigerators' main jobs were preserving food and, as air conditioners, cooling buildings. Today's high-tech world, however, demands high-tech refrigeration. Heat pumps are no longer up to the job. The search is on for something to replace them. 2 One set of candidates are known as paraelectric materials. These act like batteries when they undergo a temperature change: attach electrodes to them and they generate a current. This effect is used in infra-red cameras. An array of tiny pieces of paraelectric material can sense the heat radiated by, for example, a person, and the pattern of the array's electrical outputs can then be used to construct an image. But until recently no one had bothered much with the inverse of this process. That inverse exists, however. Apply an appropriate current to a paraelectric material and it will cool down. 3 Someone who is looking at this inverse effect is Alex Mischenko, of Cambridge University. Using commercially available paraelectric film, he and his colleagues have generated temperature drops five times bigger than any previously recorded. That may be enough to change the phenomenon from a laboratory curiosity to something with commercial applications. 4 As to what those applications might be, Dr Mischenko is still a little hazy. He has, nevertheless, set up a company to pursue them. He foresees putting his discovery to use in more efficient domestic fridges and air conditioners. The real money, though, may be in cooling computers. 5 Gadgets containing microprocessors have been getting hotter for a long time. One consequence of Moore's Law,which describes the doubling of the number of transistors on a chip every 18 months, is that the amount of heat produced doubles as well. In fact, it more than doubles, because besides increasing in number, the components are getting faster. Heat is released every time a logical operation is performed inside a microprocessor, so the faster the processor is, the more heat it generates. Doubling the frequency quadruples the heat output. And the frequency has doubled a lot. The first Pentium chips sold by Dr Moore's company, Intel, in 1993, ran at 60m cycles a second. The Pentium 4--the last "single-core" desktop processor--clocked up 3.2 billion cycles a second. 6 Disposing of this heat is a big obstruction to further miniaturisation and higher speeds. The innards of a desktop computer commonly hit 80℃. At 85℃, they stop working. Tweaking the processor's heat sinks (copper or aluminium boxes designed to radiate heat away) has reached its limit. So has tweaking the fans that circulate air over those heat sinks. And the idea of shifting from single-core processors to systems that divided processing power between first two, and then four, subunits, in order to spread the thermal load, also seems to have the end of the road in sight. 7 One way out of this may be a second curious physical phenomenon, the thermoelectric effect. Like paraelectric materials, this generates electricity from a heat source and produces cooling from an electrical source. Unlike paraelectrics, a significant body of researchers is already working on it. 8 The trick to a good thermoelectric material is a crystal structure in which electrons can flow freely, but the path of phonons--heat-carrying vibrations that are larger than electrons--is constantly interrupted. In practice, this trick is hard to pull off, and thermoelectric materials are thus less efficient than paraelectric ones (or, at least, than those examined by Dr Mischenko).

At 9:30 amB. At 10:00 amC. At 10:30 am答案：A二、阅读部分1. According to the passage, what is the primary function of the enzyme in question?A. It breaks down proteins.B. It aids in digestion.C. It prevents blood clotting.答案：C2. What does the author suggest about the future of the species discussed?A. It will become extinct.B. It will adapt to the changing environment.C. It will migrate to a new habitat.答案：B三、写作部分1. Task 1: The chart below shows the percentage of people in different age groups who used the internet in a European country in 2014.Summarize the information by selecting and reporting the main features, and make comparisons where relevant.答案：The chart illustrates the internet usage among different age groups in a European country in 2014. It is evident that the highest percentage of internet users was among the 25-34 age group, accounting for 92%. In contrast, the lowest usage was observed in the 65-74 age group, with only 46% of individuals accessing the internet. The 15-24 and 35-44 age groups had similar internet usage rates, both around 80%.2. Task 2: Some people believe that the increasing use of computers and mobile phones for communication has had a negative impact on young people's reading and writing skills. To what extent do you agree or disagree with this opinion? Give reasons for your answer and include any relevant examples from your own knowledge or experience.答案：I agree that the increasing reliance on technology forcommunication has had a detrimental effect on young people's reading and writing skills. Firstly, the instant nature of electronic communication encourages brevity and informality, which can lead to a decline in the use of proper grammar and punctuation. Secondly, the ease of editing and spell-checking tools may reduce the motivation to learn these skills thoroughly. However, it is also important to acknowledge that technology has made information more accessible and has the potential to enhance learning through interactive platforms. Overall, while technology has its benefits, it is crucial to ensure that young people continue to develop strong reading and writing skills alongside their digital literacy.四、口语部分1. Describe a book you have read recently.答案：I recently read "To Kill a Mockingbird" by Harper Lee. The book is set in the 1930s in a small Southern town and follows the story of Scout Finch, her brother Jem, and their father Atticus Finch, who is a lawyer. The story deals with themes of racial injustice and moral growth, and it's a powerful exploration of human nature. I found the characters to be well-developed and the plot engaging, making it a thought-provoking and enjoyable read.2. What do you think are the benefits of learning a foreign language?答案：Learning a foreign language has numerous benefits. Firstly,it enhances cognitive abilities, such as memory and problem-solving skills. Secondly, it broadens cultural understanding and fosters global awareness. Additionally, it can improve job prospects and provide opportunities for travel and international connections. Lastly, learning a new language is a rewarding challenge that can boost self-confidence and personal growth.。

2014年雅思阅读模拟试题及答案解析（4）
Selling Digital Music without Copy-protection Makes SenseA. It was uncharacteristically low-key for the industry’s greatest showman. But the essay published this week by Steve Jobs， the boss of Apple， on his firm’s website under the unassuming title “Thoughts on Music” has nonetheless provoked a vigorous debate about the future of digital music， which Apple dominates with its iPod music-player and iTunes music-store. At issue is “digital rights management”(DRM)—the technology guarding downloaded music against theft. Since there is no common standard for DRM， it also has the side-effect that songs purchased for one type of music-player may not work on another. Apple’s DRM system， called FairPlay，is the most widespread. So it came as a surprise when Mr. Jobs called for DRM for digital music to be abolished.B. This is a change of tack for Apple. It has come under fire from European regulators who claim that its refusal to license FairPlay to other firms has “locked in” customers. Since music from the iTunes store cannot be played on non-iPod music-players (at least not without a lot of fiddling)， any iTunes buyer will be deterred from switching to a device made by a rival firm， such as Sony or Microsoft. When French lawmakers drafted a bill last year compelling Apple to open up FairPlay to rivals， the company warned of “state-sponsored piracy”. Only DRM， it implied，could keep the pirates at bay.C. This week Mr. Jobs gave another explanation for his former defence of DRM：the record companies made him do it. They would make their music available to the iTunes store only if Apple agreed to protect it using DRM. They can still withdraw their catalogues if the DRM system is compromised. Apple cannot license FairPlay to others， says Mr Jobs， because it would depend on them to produce security fixes promptly. All DRM does is restrict consumer choice and provide a barrier to entry，says Mr Jobs； without it there would be far more stores and players， and far more innovation. So， he suggests， why not do away with DRM and sell music unprotected？“This is clearly the best alternative for consumers，” he declares，“and Apple would embrace it in a heartbeat.”D. Why the sudden change of heart？ Mr Jobs seems chiefly concerned with getting Europe’s regulators off his back. Rather than complaining to Apple about its use of DRM， he suggests，“those unhappy with the current situation should redirect their energies towards persuading the music companies to sell their music DRM-free.” Two and a half of the four big record companies， he helpfully points out， are European-owned. Mr Jobs also hopes to paint himself as a consumer champion. Apple resents accusations that it has become the Microsoft of digital music.E. Apple can afford to embrace open competition in music players and online stores. Consumers would gravitate to the best player and the best store， and at the moment that still means Apple’s. Mr Jobs is evidently unfazed by rivals to the iPod. Since only 3% of the music in a typical iTunes library is protected， most of it can already be used on other players today， he notes. (And even the protected tracks can be burned onto a CD and then re-ripped.) So Apple’s dominance evidently depends far more on branding and ease of use than DRM-related “lock in”.F. The music giants are trying DRM-free downloads. Lots of smaller labels already sell music that way. Having seen which way the wind is blowing， Mr Jobs now wants to be seen not as DRM’s defender， but as a consumer champion who helped in its downfall. Wouldn’t it lead to a surge in piracy？ No， because most music is still sold unprotected on CDs， people wishing to steal music already can do so. Indeed， scrapping DRM would probably increase online-music sales by reducing confusion and incompatibility. With the leading online store， Apple would benefit most. Mr Jobs’s argument， in short， is transparently self-serving. It also happens to be right.Questions 1-7 Do the following statemets reflect the claims of the writer in Reading Passage 1？Write your answer in Boxes 1-7 on your answer sheet.TRUE if the statement reflets the claims of the writerFALSE if the statement contradicts the claims of the writerNOT GIVEN if it is impossbile to say what the writer thinks about this1. Apple enjoys a controlling position in digital music market with its iPod music-player and iTunes music-store.2. DRM is a government decree issued with a purpose to protect downloaded music from theft by consumers.3. Lack of standardization in DRM makes songs bought for one kind of music player may not function on another.4. Apple has been criticized by European regulators since it has refused to granta license FairPlay to other firms.5. All music can be easily played on non-iPod music devices from Sony or Microsoft without too much fiddling.6. Apple depends far more on DRM rather than branding for its dominance of the digital music devices.7. If DRM was cancelled， Sony would certainly dominate the international digital music market.Questions 8-10 Choose the appropriate letters A-D and write them in boxes 8-10 on your answe sheet.8. Which of the following statements about Mr. Jobs’ idea of DRM is NOT TRUE？A. DRM places restrictions on consumer’ choice of digital music products available.B. DRM comples iTunes buyers to switch to a device made by Sony or Microsoft.C. DRM constitutes a barrier for potential consumers to enter digital music markets.D. DRM hinders development of more stores and players and technical innovation.9. The word “unfazed” in line 3 of paragraph E， means___________.A. refusedB. welcomedC. not botheredD. not well received10. Which of the following statements is TRUE if DRM was scapped？A. Sony would gain the most profit.B. More customers would be “locked in”.C. A sudden increase in piracy would occur.D. Online-music sales would probably decrease.Questions 11-14 Complete the notes below.Choose NO MORE THAN THREE WORDS from Reading Passage 1 for each answer.Write your answers in boxes 11-14 on your answer sheet.Mr. Steve Jobs， the boss of Apple， explains the reason why he used to defend DRM， saying that the company was forced to do so： the record companies would make their music accessible to …11...only if they agreed to protect it using DRM； they can still…12…if the DRM system is compromised.

2014年雅思阅读模拟试题(卷)
2014年雅思阅读模拟试题(1)When was the last time you saw a frog? Chances are, if you live in a city, you have not seen one for some time. Even in wet areas once teeming with frogs and toads, it is BEComing less and less easy to find those slimy, hopping and sometimes poisonous members of the animal kingdom. All over the world, and even in remote parts of Australia, frogs are losing the ecological battle for survival, and biologists are at a loss to explain their demise. Are amphibians simply oversensitive to changes in the ecosystem? Could it be that their rapid decline in numbers is signaling some coming environmental disaster for us all? This frightening scenario is in part the consequence of a dramatic increase over the last quarter century in the development of once natural areas of wet marshland; home not only to frogs but to all manner of wildlife. However, as yet, there are no obvious reasons why certain frog species are disappearing from rainforests in Australia that have barely been touched by human hand. The mystery is unsettling to say the least, for it is known that amphibian species are extremely sensitive to environmental variations in temperature and moisture levels. The danger is that planet Earth might not only lose a vital link in the ecological food chain (frogs keep populations of otherwise pestilent insects at manageable levels), but we might be increasing our output of air pollutants to levels that may have already become irreversible. Frogs could be inadvertently warning us of a catastrophe.An example of a species of frog that, at far as is known, has become extinct, is the platypus frog. Like the well-known Australian mammal it was named after, it exhibited some very strange behaviour; instead of giving birth to tadpoles in the water, it raised its young within its stomach. The baby frogswere actually born from out of their mother's mouth. Discovered in 1981, less than ten years later the frog had completely vanished from the crystal clear waters of Booloumba Creek near Queensland's Sunshine Coast. Unfortunately, this freak of nature is not the only frog species to have been lost in Australia. Since the 1970s, no less than eight others have suffered the same fate.One theory that seems to fit the facts concerns the depletion of the ozone layer, a well documented phenomenon which has led to a sharp increase in ultraviolet radiation levels.The ozone layer is meant to shield the Earth from UV rays, but increased radiation may be having a GREater effect upon frog populations than previously believed.

Already, millions of people around the world are linked by computer simply by having a modem and an address on the `Net', in much the same way that owning a telephone links us to almost anyone who pays a phone bill. In fact, since the computer connections are made via the phone line, the Internet can be envisaged as a network of visual telephone links. It remains to seen in which direction the Information Superhighway is headed, but many believeit is the educational hope of the future.The World Wide Web, an enormous collection of Internet addresses or sites, all of which can be accessed for information, has been mainly responsible for the increase in interest in the Internet in the 1990s. Before the World Wide Web, the `Net' was comparable to an integrated collection of computerized typewriters, but the introduction of the `Web' in 1990 allowed not only text links to be made but also graphs, images and even video.A Web site consists of a `home page', the first screen of a particular site on the computer to which you are connected, from where access can be had to other subject related `pages'(or screens) at the site and on thousands of other computers all over the world. This is achieved by a process called `hypertext'. By clicking with a mouse device on various parts of the screen, a person connected to the `Net' can go traveling, or surfing' through a of the screen, a person connected to the `Net' can go traveling, or `surfing' through a web of pages to locate whatever information is required.Anyone can set up a site; promoting your club, your institution, your company's products or simply yourself, is what the Web and the Internet is all about. And what is more, information on the Internet is not owned or controlled by any one organization. It is, perhaps, true to say that no one and therefore everyone owns the `Net'. BECause of the relative freedom of access to information, the Internet has often been criticised by the media as a potentially hazardous tool in the hands of young computer users. This perception has proved to be largely false however, and the vast majority of users both young and old get connected with the Internet for the dual purposes for which it was intended - discovery and delight.TRUE/FALSE/NOT GIVEN1.Everyone is aware of the Information Superhighway.ing the Internet costs the owner of a telephone extra money.3.Internet computer connections are made by using telephone lines.4.The World Wide Web is a network of computerised typewriters.5.According to the author, the Information Superhighway may be the future hope of education.6.The process called`hypertext'requires the use of a mouse device.7.The Internet was created in the 1990s.8.The `home page'is the first screen of a `Web'site on the `Net'.9.The media has often criticised the Internet because it is dangerous.10.

Don’t wash those fossils！Standard museum practice can wash away DNA.1. Washing， brushing and varnishing fossils — all standard conservation treatments used by many fossil hunters and museum curators alike — vastly reduces the chances of recovering ancient DNA.2. Instead， excavators should be handling at least some of their bounty with gloves， and freezing samples as they are found， dirt and all， concludes a paper in the Proceedings of the National Academy of Sciences today.3. Although many palaeontologists know anecdotally that this is the best way to up the odds of extracting good DNA，Eva-Maria Geigl of the Jacques Monod Institute in Paris，France， and her colleagues have now shown just how important conservation practices can be. This information， they say，needs to be hammered home among the people who are actually out in the field digging up bones.4. Geigl and her colleagues looked at 3，200-year-old fossil bones belonging to a single individual of an extinct cattle species， called an aurochs. The fossils were dug up at a site in France at two different times — either in 1947， and stored in a museum collection， or in 2004， and conserved in sterile conditions at -20 oC.5. The team’s attempts to extract DNA from the 1947 bones all failed. The newly excavated fossils， however， all yielded DNA.6. Because the bones had been buried for the same amount of time， and in the same conditions， the conservation method had to be to blame says Geigl. “As much DNA was degraded in these 57 years as in the 3，200 years before，” she says.Wash in，wash out7. Because many palaeontologists base their work on the shape of fossils alone， their methods of conservation are not designed to preserve DNA， Geigl explains.8. The biggest problem is how they are cleaned. Fossils are often washed together on-site in a large bath， which can allow water — and contaminants in the form of contemporary DNA —to permeate into the porous bones. “Not only is the authentic DNA getting washed out， but contamination is getting washed in，” says Geigl.9. Most ancient DNA specialists know this already， says Hendrik Poinar， an evolutionary geneticist at McMaster University in Ontario， Canada. But that doesn’t mean that best practice has become widespread among those who actually find the fossils.10. Getting hold of fossils that have been preserved with their DNA in mind relies on close relationships betweenlab-based geneticists and the excavators， says palaeogeneticist Svante P bo of the Max Planck Institute for Evolutionary Anthropology in Leipzig， Germany. And that only occurs in exceptional cases， he says.11. P bo’s team， which has been sequencing Neanderthal DNA， continually faces these problems. “When you want to study ancient human and Neanderthal remains， there’s a big issue of contamination with contemporary human DNA，” hesays.12. This doesn’t mean that all museum specimens are fatally flawed， notes P bo. The Neanderthal fossils that were recently sequenced in his own lab， for example， had been part of a museum collection treated in the traditional way. But P bo is keen to see samples of fossils from every major find preserved in line with Geigl’s recommendations — just in case.在我们看来，阅读的满分并不是遥不可及的！点这里，告诉你满分是如何炼成的Warm and wet13. Geigl herself believes that， with cooperation between bench and field researchers， preserving fossils properly could open up avenues of discovery that have long been assumed closed.14. Much human cultural development took place in temperate regions. DNA does not survive well in warm environments in the first place， and can vanish when fossils are washed and treated. For this reason， Geigl says， most ancient DNA studies have been done on permafrost samples， such as the woolly mammoth， or on remains sheltered from the elements in cold caves — including cave bear and Neanderthal fossils.15. Better conservation methods， and a focus on fresh fossils， could boost DNA extraction from more delicate specimens， says Geigl. And that could shed more light on the story of human evolution.(640 words nature )GlossaryPalaeontologists 古生物学家Aurochs 欧洲野牛Neanderthal (人类学)尼安德特人，旧石器时代的古人类。

new weapon to fight cancer1. British scientists are preparing to launch trials of a radical new way to fight cancer， which kills tumours by infecting them with viruses like the common cold.2. If successful， virus therapy could eventually form a third pillar alongside radiotherapy and chemotherapy in the standard arsenal against cancer， while avoiding some of the debilitating side-effects.3. Leonard Seymour， a professor of gene therapy at Oxford University， who has been working on the virus therapy with colleagues in London and the US， will lead the trials later this year. Cancer Research UK said yesterday that it was excited by the potential of Prof Seymour's pioneering techniques.4. One of the country's leading geneticists， Prof Seymour has been working with viruses that kill cancer cells directly， while avoiding harm to healthy tissue. "In principle， you've got something which could be many times more effective than regular chemotherapy，" he said.5. Cancer-killing viruses exploit the fact that cancer cells suppress the body's local immune system. "If a cancer doesn't do that， the immune system wipes it out. If you can get a virus into a tumour， viruses find them a very good place to be because there's no immune system to stop them replicating. You can regard it as the cancer's Achilles' heel."6. Only a small amount of the virus needs to get to the cancer. "They replicate，you get a million copies in each cell and the cell bursts and they infect the tumour cells adjacent and repeat the process，" said Prof Seymour.7. Preliminary research on mice shows that the viruses work well on tumours resistant to standard cancer drugs. "It's an interesting possibility that they may have an advantage in killing drug-resistant tumours， which could be quite different to anything we've had before."8. Researchers have known for some time that viruses can kill tumour cells and some aspects of the work have already been published in scientific journals. American scientists have previously injected viruses directly into tumours but this technique will not work if the cancer is inaccessible or has spread throughout the body.9. Prof Seymour's innovative solution is to mask the virus from the body's immune system， effectively allowing the viruses to do what chemotherapy drugs do - spread through the blood and reach tumours wherever they are. The big hurdle has always been to find a way to deliver viruses to tumours via the bloodstream without the body's immune system destroying them on the way.10. "What we've done is make chemical modifications to the virus to put a polymer coat around it - it's a stealth virus when you inject it，" he said.11. After the stealth virus infects the tumour， it replicates， but the copies do not have the chemical modifications. If they escape from the tumour， the copies will be quickly recognised and mopped up by the body's immune system.12. The therapy would be especially useful for secondary cancers， called metastases， which sometimes spread around the body after the first tumour appears. "There's an awful statistic of patients in the west ... with malignant cancers；75% of them go on to die from metastases，" said Prof Seymour.13. Two viruses are likely to be examined in the first clinical trials：adenovirus， which normally causes a cold-like illness， and vaccinia， which causes cowpox and is also used in the vaccine against smallpox. For safety reasons， both will be disabled to make them less pathogenic in the trial， but Prof Seymour said he eventually hopes to use natural viruses.14. The first trials will use uncoated adenovirus and vaccinia and will be delivered locally to liver tumours， in order to establish whether the treatment is safe in humans and what dose of virus will be needed. Several more years of trials will be needed， eventually also on the polymer-coated viruses， before the therapy can be considered for use in the NHS. Though the approach will be examined at firstfor cancers that do not respond to conventional treatments， Prof Seymour hopes that one day it might be applied to all cancers.Questions 1-6 Do the following statements agree with the information given in the reading passage？ For questions 1-6 writeTRUE if the statement agrees with the informationFALSE if the statement contradicts the informationNOT GIVEN if there is no information on this in the passage1.Virus therapy， if successful， has an advantage in eliminating side-effects.2.Cancer Research UK is quite hopeful about Professor Seymour’s work on the virus therapy.3.Virus can kill cancer cells and stop them from growing again.4.Cancer’s Achilles’ heel refers to the fact that virus may stay safely ina tumor and replicate.5.To infect the cancer cells， a good deal of viruses should be injected into the tumor.6.Researches on animals indicate that virus could be used as a new way to treat drug-resistant tumors.Question 7-9 Based on the reading passage， choose the appropriate letter from A-D for each answer.rmation about researches on viruses killing tumor cells can be found(A) on TV(B) in magazines(C) on internet(D) in newspapers8.To treat tumors spreading out in body， researchers try to(A) change the body’ immune system(B) inject chemotherapy drugs into bloodstream.(C) increase the amount of injection(D) disguise the viruses on the way to tumors.9.When the chemical modified virus in tumor replicates， the copies(A) will soon escape from the tumor and spread out.(B) will be wiped out by the body’s immune system.(C) will be immediately recognized by the researchers.(D) will eventually stop the tumor from spreading outQuestions 10-13 Complete the sentences below.
