READING PASSAGE 1You should spend about 20 minutes on Questions 1-13, which are based on Reading Passage 1 below.Johnson’s DictionaryFor the centur y before Johnson’s Dictionary was published in 1775, there had been concern about the state of the English language. There was no standard way of speaking or writing and no agreement as to the best way of bringing some order to the chaos of English spelling. Dr Johnson provided the solution.There had, of course, been dictionaries in the past, the first of these being a little book of some 120 pages, compiled by a certain Robert Cawdray, published in 1604 under the title A Table Alphabeticall ‘of hard usuall English wordes’. Like the various dictionaries that came after it during the seventeenth century, Cawdray’s tended to concentrate on ‘scholarly’ words; one function of the dictionary was to enable its student to convey an impression of fine learning.Beyond the practical need to make order out of chaos, the rise of dictionaries is associated with the rise of the English middle class, who were anxious to define and circumscribe thevarious worlds to conquer —lexical as well as social and commercial. it is highly appropriate that Dr Samuel Johnson, the very model of an eighteenth-century literary man, as famous in his own time as in ours, should have published his Dictionary at the very beginning of the heyday of the middle class.Johnson was a poet and critic who raised common sense to the heights of genius. His approach to the problems that had worried writers throughout the late seventeenth and early eighteenth centuries was intensely practical. Up until his time, the task of producing a dictionary on such a large scale had seemed impossible without the establishment of an academy to make decisions about right and wrong usage. Johnson decided he did not need an academy to settle arguments about language; he would write a dictionary himself and he would do it single-handed. Johnson signed the contract for the Dictionary with the bookseller Robert Dosley at a breakfast held at the Golden Anchor Inn near Holbom Bar on 18 June 1764.He was to be paid ￡1.575 in instalments, and from this he took money to rent Gou gh Square, in which he set up his ‘dictionary workshop’.James Boswell, his biographer, described the garret where Johnson worked as ‘fitted up like a counting house’ with a long desk running down the middle at which the copying clerks would work standing up. Johnson himself was stationed on a rickety chair at an ‘old crazy deal table’ surrounded by a chaos of borrowed books. He was also helped by six assistants, two of whom died whilst the Dictionary was still in preparation.The work was immense; filling about eighty large notebooks (and without a library to hand), Johnson wrote the definitions of over 40,000 words, and illustrated their many meanings with some 114,000 quotations drawn from English writing on everysubject, from the Elizabethans to his own time. He did not expect to achieve complete originality. Working to a deadline, he had to draw on the best of all previous dictionaries, and to make his work one of heroic synthesis. In fact, it was very much more. Unlike his predecessors, Johnson treated English very practically, as a living language, with many different shades of meaning. He adopted his definitions on the principle of English common law —according to precedent. After its publication, his Dictionary was not seriously rivalled for over a century.After many vicissitudes the Dictionary was finally published on 15 April 1775. It was instantly recognised as a landmark throughout Europe. ‘This very noble work,’ wrote the leading Italian lexicographer, ‘will be a perpetual monument of Fame to the Author, an Honour to his own Country in particular, and a general Benefit to the republic of Letters throughout Europe" The fact that Johnson had taken on the Academies of Europe and matched them (everyone knew that forty French academics had taken forty years to produce the first French national dictionary) was cause for much English celebration.Johnson had worked for nine years, ‘with little assistance of the learned, and without any patronage of the great; not in the soft obscurities of retirement, or under the shelter of academic bowers, but amidst inconvenience and distraction, in sickness and in sorrow’. For all its faults and eccentricities his two-volume work is a masterpiece and a landmark, in his own words, ‘setting the orthography, displaying the analogy, regulating the structures, and ascertaining the significations of English words’. It is the cornerstone of Standard English an achievement which, in James Boswell’s words ‘conferred stability on the language of his country.’The Dictionary, together with his other writing, made Johnson famous and so well esteemed that his friends were able to prevail upon King George Ⅲ to offer him a pension. From then on, he was to become the Johnson of folklore.Questions 1-3Choose THREE letters A-H.Write your answers in boxes 1-3 on your answer sheet.NB Your answers may be given in any order.Which THREE of the following statements are true of Johnson’s Dictionary?A It avoided all scholarly words.B It was the only English dictionary in general use for 200 years.C It was famous because of the large number of people involved.D It focused mainly on language from contemporary texts.E There was a time limit for its completion.F It ignored work done by previous dictionary writers.G It took into account subtleties of meaning.H Its definitions were famous for their originality.Questions 4-7Complete the summary.Choose NO MORE THAN TWO WORDS from the passage for each answer.Write your answers in boxes 4-7 on your answer sheet.In 1764 Dr Johnson accepted the contract to produce a dictionary. Having rented a garret, he took on a number of 4…………, who stood at a long central desk. Johnson did not have a 5………… available to him, but eventually produced definitions of in excess of 40,000 words written down in 80 large notebooks.On publications, the Dictionary was immediately hailed in many European countries as a landmark. According to his biographer, James Boswell, Johnson’s principal achievement was to bring 6……… to the English language. As a reward for his ha rd work, he was granted a 7………by the king.Questions 8-13Do the following statements agree with the information given in Reading Passage 1?In boxes 8-13 on your answer sheet, writeTRUE if the statement agrees with the informationFALSE if the statement contradicts the informationNOT GIVEN if there is no information on this8 The growing importance of the middle classes led to an increased demand for dictionaries.9 Johnson has become more well known since his death.10 Johnson had been planning to write a dictionary for several years.11 Johnson set up an academy to help with the writing of his Dictionary.12 Johnson only received payment for his Dictionary on its completion.13 Not all of the assistants survived to see the publication of the Dictionary.READING PASSAGE 2You should spend about 20 minutes on Questions 14-26, which are based on Reading Passage 2 below.Nature or Nurture?A A few years ago, in one of the most fascinating and disturbing experiments in behavioural psychology, Stanley Milgram of Yale University tested 40 subjects from all walks of lifefor their willingness to obey instructions given by a ‘leader’ in a situation in which the subjects might feel a personal distaste for the actions they were called upon to perform. Specifically M ilgram told each volunteer ‘teacher-subject’ that the experiment was in the noble cause of education, and was designed to test whether or not punishing pupils for their mistakes would have a positive effect on the pupils’ ability to learn.B Milgram’s expe rimental set-up involved placing the teacher-subject before a panel of thirty switches with labels ranging from ‘15 volts of electricity (slight shock)’ to ‘450 volts (danger —severe shock)’ in steps of 15 volts each. The teacher-subject was told that whenever the pupil gave the wrong answer to a question, a shock was to be administered, beginning at the lowest level and increasing in severity with each successive wrong answer. The supposed ‘pupil’ was in reality an actor hired by Milgram to simulate receiving the shocks by emitting a spectrum of groans, screams and writings together with an assortment of statements and expletives denouncing both the experiment and the experimenter. Milgram told the teacher-subject to ignore the reactions of the pupil, and to administer whatever level of shock was called for, as per the rule governing the experimental situation of the moment.C As the experiment unfolded, the pupil would deliberately give the wrong answers to questions posed by the teacher, thereby bringing on various electrical punishments, even up to the danger level of 300 volts and beyond. Many of the teacher-subjects balked at administering the higher levels of punishment, and turned to Milgram with questioning looks and/or complaints about continuing the experiment. In these situations, Milgramcalmly explained that the teacher-subject was to ignore the pupil’s cries for mercy and carry on with the experiment. If the subject was still reluctant to proceed, Milgram said that it was important for the sake of the experiment that the procedure be followed through to the end. His final argument was ‘you have no other choice. You must go on’. What Milgram was trying to discover was the number of teacher-subjects who would be willing to administer the highest levels of shock, even in the face of strong personal and moral revulsion against the rules and conditions of the experiment.D Prior to carrying out the experiment, Milgram explained his idea to a group of 39 psychiatrists and asked them to predict the average percentage of people in an ordinary population who would be willing to administer the highest shock level of 450 volts. The overwhelming consensus was that virtually all the teacher-subjects would refuse to obey the experimenter. The psychiatrists felt that ‘most subjects would not go beyond 150 volts’ and they further anticipated that only four per cent would go up to 300 volts. Furthermore, they thought that only a lunatic fringe of about one in 1,000 would give the highest shock of 450 volts.E What were the actual results? Well, over 60 per cent of the teacher-subjects continued to obey Milgram up to the 450-volt limit in repetitions of the experiment in other countries, the percentage of obedient teacher-subjects was even higher, reaching 85 per cent in one country. How can we possibly account for this vast discrepancy between what calm, rational, knowledgeable people predict in the comfort of their study and what pressured, flustered, but cooperative ‘teachers’ actually do in the laboratory of real life?F One’s first inclination might be to argue that there must be some sort of built-in animal aggression instinct that was activated by the experiment, and that Milgram’s teache-subjects were just following a genetic need to discharge this pent-up primal urge onto the pupil by administering the electrical shock. A modern hard-core sociobiologist might even go so far as to claim that this aggressive instinct evolved as an advantageous trait, having been of survival value to our ancestors in their struggle against the hardships of life on the plains and in the caves, ultimately finding its way into our genetic make-up as a remnant of our ancient animal ways.G An alternative to this notion of genetic programming is to see the teacher-subjects’ actions as a result of the social environment under which the experiment was carried out. As Milgram himself pointed out, ‘Most subjects in the experiment see their behaviour in a larger context that is benevolent and useful to society —the pursuit of scientific truth. The psychological laboratory has a strong claim to legitimacy and evokes trust and confidence in those who perform there. An action such as shocking a victim, which in isolation appears evil, acquires a completely different meaning when placed in this se tting.’H Thus, in this explanation the subject merges his unique personality and personal and moral code with that of larger institutional structures, surrendering individual properties like loyalty, self-sacrifice and discipline to the service of malevolent systems of authority.I Here we have two radically different explanations for why so many teacher-subjects were willing to forgo their sense of personal responsibility for the sake of an institutional authorityfigure. The problem for biologists, psychologists and anthropologists is to sort out which of these two polar explanations is more plausible. This, in essence, is the problem of modern sociobiology — to discover the degree to which hard-wired genetic programming dictates, or at least strongly biases, the interaction of animals and humans with their environment, that is, their behaviour. Put another way, sociobiology is concerned with elucidating the biological basis of all behaviour.Questions 14-19Reading Passage 2 has nine paragraphs, A-I.Which paragraph contains the following information?Write the correct letter A-I in boxes 14-19 on your answer sheet.14 a biological explanation of the teacher-subjects’ behaviour15 the explanation Milgram gave the teacher-subjects for the experiment16 the identity of the pupils17 the expected statistical outcome18 the general aim of sociobiological study19 the way Milgram persuaded the teacher-subjects to continueQuestions 20-22Choose the correct letter, A, B, C or D.Write your answers in boxes 20-22 on your answer sheet.20 The teacher-subjects were told that were testing whetherA a 450-volt shock was dangerous.B punishment helps learning.C the pupils were honest.D they were suited to teaching.21 The teacher-subjects were instructed toA stop when a pupil asked them to.B denounce pupils who made mistakes.C reduce the shock level after a correct answer.D give punishment according to a rule.22 Before the experiment took place the psychiatristsA believed that a shock of 150 volts was too dangerous.B failed to agree on how the teacher-subjects would respond to instructions.C underestimated the teacher-subjects’ willingness to comply with experimental procedure.D thought that many of the teacher-subjects would administer a shock of 450 volts.Questions 23-26Do the following statements agree with the information given in Reading Passage 2?In boxes 23-26 on your answer sheet, writeTRUE if the statement agrees with the informationFALSE if the statement contradicts the informationNOT GIVEN if there is no information on this23 Several of the subjects were psychology students at Yale University.24 Some people may believe that the teacher-subjects’ behaviour could be explained as a positive survival mechanism.25 In a sociological explanation, personal values are more powerful than authority.26 Milgram’s experiment solves an important question in sociobiology.READING PASSAGE 3You should spend about 20 minutes on Questions 27-40,which are based on Reading Passage 3 below.The Truth about the EnvironmentFor many environmentalists, the world seems to be getting worse. They have developed a hit-list of our main fears: that natural resources are running out; that the population is ever growing, leaving less and less to eat; that species are becoming extinct in vast numbers, and that the planet’s air and water are becoming ever more polluted.But a quick look at the facts shows a different picture. First, energy and other natural resources have become more abundant, not less so, since the book ‘The Limits to Growth’ was published in 1972 by a group of scientists. Second, more food is now produced per head of the world’s population than at any time in history. Fewer people are starving. Third, although species are indeed becoming extinct, only about 0.7% of them are expected to disappear in the next 50 years, not 25-50%, as has so often been predicted. And finally, most forms of environmental pollution either appear to have been exaggerated, or are transient —associated with the early phases of industrialisation and therefore best cured not by restricting economic growth, but by accelerating it. One form of pollution — the release of greenhouse gases that causes global warming — does appear to be a phenomenon that is going to extend well into our future, but its total impact is unlikely to pose a devastating problem. A bigger problem may well turn out to be an inappropriate response to it.Yet opinion polls suggest that many people nurture the belief that environmental standards are declining and four factors seem to cause this disjunction between perception and reality.One is the lopsidedness built into scientific research. Scientific funding goes mainly to areas with many problems. That may be wise policy, but it will also create an impression that many more potential problems exist than is the case.Secondly, environmental groups need to be noticed by the mass media. They also need to keep the money rolling in. Understandably, perhaps, they sometimes overstate their arguments. In 1997, for example, the World Wide Fund for Nature issued a press release entitled: ‘Two thirds of the world’s forests lost forever.’ The truth turns out to be nearer 20%.Though these groups are run overwhelmingly by selfless folk, they nevertheless share many of the characteristics of other lobby groups. That would matter less if people applied the same degree of scepticism to environmental lobbying as they do to lobby groups in other fields. A trade organisation arguing for, say, weaker pollution controls is instantly seen as self-interested. Yet a green organisation opposing such a weakening is seen as altruistic, even if an impartial view of the controls in question might suggest they are doing more harm than good.A third source of confusion is the attitude of the media. People are clearly more curious about bad news than good. Newspapers and broadcasters are there to provide what the public wants. That, however, can lead to significant distortions of perception. An example was America’s encounter with El Nino in 1997 and 1998. This climatic phenomenon was accused of wrecking tourism, causing allergies, melting the ski-slopes and causing 22 deaths. However, according to an article in the Bulletin of the American Meteorological Society, the damage it did was estimated at US$4 billion but the benefits amounted to some US$19 billion. These came from higher winter temperatures(which saved an estimated 850 lives, reduced heating costs and diminished spring floods caused by meltwaters).The fourth factor is poor individual perception. People worry that the endless rise in the amount of stuff everyone throws away will cause the world to run out of places to dispose of waste. Yet, even if America’s trash output continues to rise as it has done in the past, and even if the American population doubles by 2100, all the rubbish America produces through the entire 21st century will still take up only one-12,000th of the area of the entire United States.So what of global warming? As we know, carbon dioxide emissions are causing the planet to warm. The best estimates are that the temperatures will rise by 2-3℃ in this century, causing considerable problems, at a total cost of US$5,000 billion.Despite the intuition that something drastic needs to be done about such a costly problem, economic analyses clearly show it will be far more expensive to cut carbon dioxide emissions radically than to pay the costs of adaptation to the increased temperatures. A model by one of the main authors of the United Nations Climate Change Panel shows how an expected temperature increase of 2.1 degrees in 2100 would only be diminished to an increase of 1.9 degrees. Or to put it another way, the temperature increase that the planet would have experienced in 2094 would be postponed to 2100.So this does not prevent global warming, but merely buys the world six years. Yet the cost of reducing carbon dioxide emissions, for the United States alone, will be higher than the cost of solving the world’s single, most pressing health problem: providing universal access to clean drinking water and sanitation. Such measures would avoid 2 million deaths every year, andprevent half a billion people from becoming seriously ill.It is crucial that we look at the facts if we want to make the best possible decisions for the future. It may be costly to be overly optimistic — but more costly still to be too pessimistic.Questions 27-32Do the following statements agree with the claims of the writer in Reading Passage 3?In boxes 27-32 on your answer sheet, writeYES if the statement ag rees with the writer’s claimsNO if the statement contradicts the writer’s clamsNOT GIVEN if it is impossible to say what the writer thinks about this27 Environmentalists take a pessimistic view of the world fora number of reasons28 Data on the Earth’s natural resources has only been collected since 1972.29 The number of starving people in the world has increased in recent years.30 Extinct species are being replaced by new species.31 Some pollution problems have been correctly linked to industrialisation.32 It would be best to attempt to slow down economic growth.Questions 33-37Choose the correct letter, A, B, C or D.Write your answers in boxes 33-37 on your answer sheet.33 What aspect of scientific research does the writer express concern about in paragraph 4?A the need to produce resultsB the lack of financial supportC the selection of areas to researchD the desire to solve every research problem34 The writer quotes from the Worldwide Fund for Nature to illustrate howA influential the mass media can be.B effective environmental groups can be.C the mass media can help groups raise funds.D environmental groups can exaggerate their claims.34 What is the writer’s main point about lobby groups in paragraph 6?A Some are more active than others.B Some are better organised than others.C Some receive more criticism than others.D Some support more important issues than others.35 The writer suggests that newspapers print items that are intended toA educate readers.B meet their readers’ expec tations.C encourage feedback from readers.D mislead readers.36 What does the writer say about America’s waste problem?A It will increase in line with population growth.B It is not as important as we have been led to believe.C It has been reduced through public awareness of the issues.D It is only significant in certain areas of the country.Questions 38-40Complete the summary with the list of words A-I below.Write the correct letter A-I in boxes 38-40 on your answer sheet.GLOBAL WARMINGThe writer admits that global warming is a 38…………….challenge, but says that it will not have a catastrophic impact on our future, if we deal with it in the 39…………… way.

剑桥雅思8-第三套试题-阅读部分-PASSAGE 1-阅读真题原文部分:READING PASSAGE 1You should spend about 20 minutes on Questions 1-13 which are based on Reading Passage 1 below.Striking Back at Lightning With LasersSeldom is the weather more dramatic than when thunderstorms strike. Their electrical fury inflicts death or serious injury on around 500 people each year in the United States alone. As the clouds roll in, a leisurely round of golf can become a terrifying dice with death - out in the open, a lone golfer may be a lightning bolt's most inviting target. And there is damage to property too. Lightning damage costs American power companies more than $100 million a year.But researchers in the United States and Japan are planning to hit back. Already in laboratory trials they have tested strategies for neutralising the power of thunderstorms, and this winter they will brave real storms, equipped with an armoury of lasers that they will be pointing towards the heavens to discharge thunderclouds before lightning can strike.The idea of forcing storm clouds to discharge their lightning on command is not new. In the early 1960s, researchers tried firing rockets trailing wires into thunderclouds to set up an easy discharge path for the huge electric charges that these clouds generate. The technique survives to this day at a test site in Florida run by the University of Florida, with support from the Electrical Power Research Institute (EPRI), based in California. EPRI, which is funded by power companies, is looking at ways to protect the United States' power grid from lightning strikes. 'We can cause the lightning to strike where we want it to using rockets, ' says Ralph Bernstein, manager of lightning projects at EPRI. The rocket site is providing precise measurements of lightning voltages and allowing engineers to check how electrical equipment bears up.Bad behaviourBut while rockets are fine for research, they cannot provide the protection from lightning strikes that everyone is looking for. The rockets cost around $1, 200 each, can only be fired at a limited frequency and their failure rate is about 40 per cent. And even when they do trigger lightning, things still do not always go according to plan. 'Lightning is not perfectly well behaved, 'says Bernstein. 'Occasionally, it will take a branch and go someplace it wasn't supposed to go. ' And anyway, who would want to fire streams of rockets in a populated area? 'What goes up must come down, ' points out Jean-Claude Diels of the University of New Mexico. Diels is leading a project, which is backed by EPRI, to try to use lasers to discharge lightning safely - and safety is a basic requirement since no one wants to put themselves or their expensive equipment at risk. With around $500, 000 invested so far, a promising system is just emerging from the laboratory.The idea began some 20 years ago, when high-powered lasers were revealing their ability to extract electrons out of atoms and create ions. If a laser could generate a line of ionisation in the air all the way up to a storm cloud, this conducting path could be used to guide lightning to Earth, before the electric field becomes strong enough to break down the air in an uncontrollable surge. To stop the laser itself being struck, it would not be pointed straight at the clouds. Instead it would be directed at a mirror, and from there into the sky. The mirror would be protected by placing lightning conductors close by. Ideally, the cloud-zapper (gun)would be cheap enough to be installed around all key power installations, and portable enough to be taken to international sporting events to beam up at brewing storm clouds.A stumbling blockHowever, there is still a big stumbling block. The laser is no nifty portable: it's a monster that takes up a whole room. Diels is trying to cut down the size and says that a laser around the size of a small table is in the offing. He plans to test this more manageable system on live thunderclouds next summer.Bernstein says that Diels's system is attracting lots of interest from the power companies. But they have not yet come up with the $5 million that EPRI says will be needed to develop a commercial system, by making the lasers yet smaller and cheaper. 'I cannot say I have money yet, but I'm working on it, ' says Bernstein. He reckons that the forthcoming field tests will be the turning point - and he's hoping for good news. Bernstein predicts 'an avalanche of interest and support' if all goes well. He expects to see cloud-zappers eventually costing 100, 000 each.Other scientists could also benefit. With a lightning 'switch' at their fingertips, materials scientists could find out what happens when mighty currents meet matter. Diels also hopes to see the birth of 'interactive meteorology' - not just forecasting the weather but controlling it. 'If we could discharge clouds, we might affect the weather, ' he says.And perhaps, says Diels, we'll be able to confront some other meteorological menaces. 'We think we could prevent hail by inducing lightning, ' he says. Thunder, the shock wave that comes from a lightning flash, is thought to be the trigger for the torrential rain that is typical of storms. A laser thunder factory could shake the moisture out of clouds, perhaps preventing the formation of the giant hailstones that threaten crops.

剑桥雅思6Test3Passage3原文You should spend about 20 minutes on Questions 28-40, which are based on Reading Passage 3 below.The Search for the Anti-aging PillIn government laboratories and elsewhere, scientists are seeking a drug able to prolong life and youthful vigor. Studies of caloric restriction are showing the wayAs researchers on aging noted recently, no treatment on the market today has been proved to slow human aging — the build-up of molecular and cellular damage that increases vulnerability to infirmity as we grow older. But one intervention, consumption of a low-calorie*yet nutritionally balanced diet, works incredibly well in a broad range of animals, increasing longevity and prolonging good health. Those findings suggest that caloric restriction could delay aging and increase longevity in humans, too.Unfortunately, for maximum benefit, people would probably have to reduce their caloric intake by roughly thirty per cent, equivalent to dropping from 2,500 calories a day to 1,750. Few mortals could stick to that harsh a regimen, especially for years on end. But what if someone could create a pill that mimicked the physiological effects of eating less without actually forcing people to eat less? Could such a ‘caloric-restriction mimetic’, as we call it, enable people to stay healthy longer, postponing age-related disorders (such as diabetes, arteriosclerosis, heart disease and cancer) until very late in life? Scientists first posed this question in the mid-1990s, after researchers came upon a chemical agent that in rodents seemed to reproduce many of caloric restriction’s benefits. No compound that would safely achieve the same feat in people has been found yet, but the search has been informative and has fanned hope that caloric-restriction (CR) mimetics can indeed be developed eventually.The benefits of caloric restrictionThe hunt for CR mimetics grew out of a desire to better understand caloric restriction’s many effects on the body. Scientists first recognized the value of the practice more than 60 years ago, when they found that rats fed a low-calorie diet lived longer on average than free-feeding rats and also had a reduced incidence of conditions that become increasingly common in old age. What is more, some of the treated animals survived longer than the oldest-living animals in the control group, which means that the maximum lifespan (the oldest attainable age), not merely the normal lifespan, increased. Various interventions, such as infection-fighting drugs, can increase a population’s average survival time, but only approaches that slow the body’s rate of aging will increase the maximum lifespan.The rat findings have been replicated many times and extended to creatures ranging from yeast to fruit flies, worms, fish, spiders, mice and hamsters. Until fairly recently, the studies were limited to short-lived creatures genetically distant from humans. But caloric-restriction projects underway in two species more closely related to humans — rhesus and squirrel monkeys — have made scientists optimistic that CR mimetics could help people.calorie: a measure of the energy value of foodThe monkey projects demonstrate that, compared with control animals that eat normally, caloric-restricted monkeys have lower body temperatures and levels of the pancreatic hormone insulin, and they retain more youthful levels of certain hormones that tend to fall with age.The caloric-restricted animals also look better on indicators of risk for age-related diseases. For example, they have lower blood pressure and triglyceride levels (signifying a decreased likelihood of heart disease), and they have more normal blood glucose levels (pointing to a reduced risk for diabetes, which is marked by unusually high blood glucose levels). Further, it has recently been shown that rhesus monkeys kept on caloric-restricted diets for an extended time (nearly 15 years) have less chronic disease. They and the other monkeys must be followed still longer, however, to know whether low-calorie intake can increase both average and maximum life spans in monkeys. Unlike the multitude of elixirs being touted as the latest anti-aging cure, CR mimetics would alter fundamental processes that underlie aging. We aim to develop compounds that fool cells into activating maintenance and repair.How a prototype caloric-restriction mimetic worksThe best-studied candidate for a caloric-restriction mimetic, 2DG (2-deoxy-D-glucose), works by interfering with the way cells process glucose. It has proved toxic at some doses in animals and so cannot be used in humans. But it has demonstrated that chemicals can replicate the effects of caloric restriction; the trick is finding the right one.Cells use the glucose from food to generate ATP (adenosine triphosphate), the molecule that powers many activities in the body. By limiting food intake, caloric restriction minimizes the amount of glucose entering cells and decreases ATP generation. When 2DG is administered to animals that eat normally, glucose reaches cells in abundance but the drug prevents most of it from being processed and thus reduces ATP synthesis. Researchers have proposed several explanations for why interruption of glucose processing and ATP production might retard aging. One possibility relates to the ATP-making machinery’s emission of free radicals, which are thought to contribute to aging and to such age-related diseases as cancer by damaging cells. Reduced operation of the machinery should limit their production and thereby constrain the damage. Another hypothesis suggests that decreased processing of glucose could indicate to cells that food is scarce (even if it isn’t) and induce them to shift into an anti-aging mode。

剑桥雅思阅读9原文(test3)READING PASSAGE 1You should spend about 20 minutes on Questions 1-13, which are based on Reading Passage 1 below.Attitudes to languageIt is not easy to be systematic and objective about language study. Popular linguistic debate regularly deteriorates into invective and polemic. Language belongs to everyone, so most people feel they have a right to hold an opinion about it. And when opinions differ, emotions can run high. Arguments can start as easily over minor points of usage as over major policies of linguistic education.Language, moreover, is a very public behaviour, so it is easy for different usages to be noted and criticised. No part of society or social behaviour is exempt: linguistic factors influence how we judge personality, intelligence, social status, educational standards, job aptitude, and many other areas of identity and social survival. As a result, it is easy to hurt, and to be hurt, when language use is unfeelingly attacked.In its most general sense, prescriptivism is the view that one variety of language has an inherently higher value than others, and that this ought to be imposed on the whole of the speech community. The view is propounded especially in relation to grammar and vocabulary, and frequently with reference topronunciation. The variety which is favoured, in this account, is usually a version of the ‘standard’ written language, especially as encountered in literature, or in the formal spoken language which most closely reflects this style. Adherents to this variety are said to speak or write ‘correctly’; deviations fr om it are said to be ‘incorrect’.All the main languages have been studied prescriptively, especially in the 18th century approach to the writing of grammars and dictionaries. The aims of these early grammarians were threefold: (a) they wanted to codify the principles of their languages, to show that there was a system beneath the apparent chaos of usage, (b) they wanted a means of settling disputes over usage, and (c) they wanted to point out what they felt to be common errors, in order to ‘improve’ the la nguage. The authoritarian nature of the approach is best characterized by its reliance on ‘rules’ of grammar. Some usages are ‘prescribed’, to be learnt and followed accurately; others are ‘proscribed’, to be avoided. In this early period, there were no half-measures: usage was either right or wrong, and it was the task of the grammarian not simply to record alternatives, but to pronounce judgement upon them.These attitudes are still with us, and they motivate a widespread concern that linguistic standards should be maintained. Nevertheless, there is an alternative point of view that is concerned less with standards than with the facts of linguistic usage. This approach is summarized in the statement that it is the task of the grammarian to describe, not prescribe —to record the facts of linguistic diversity, and not to attempt the impossible tasks of evaluating language variation or halting language change. In the second half of the 18th century, wealready find advocates of this view, such as Joseph Priestley, whose Rudiments of English Grammar (1761) insists that ‘the custom of speaking is the original and only just standard of any language’. Linguistic issue, it is argued, cannot be solved by logic and legislation. And this view has become the tenet of the modern linguistic approach to grammatical analysis.In our own time, the opposition between ‘descriptivists’ and ‘prescriptivists’ has often become extreme, with both sides painting unreal pictures of the other. Descriptive grammarians have been presented as people who do not care about standards, because of the way they see all forms of usage as equally valid. Prescriptive grammarians have been presented as blind adherents to a historical tradition. The opposition has even been presented in quasi-political terms —of radical liberalism vs elitist conservatism.Questions 1-8Do the following statements agree with the claims of the writer in Reading Passage 1?In boxes 1-8 on your answer sheet, writeYES if the statement agrees with the claims of the writerNO if the statement contradicts the claims of the writerNOT GIVEN if it is impossible to say what the writer thinks about this1 There are understandable reasons why arguments occur about language.2 People feel more strongly about language education than about small differences in language usage.3 Our assessment of a person’s intelligence is affected by the way he or she uses language.4 Prescriptive grammar books cost a lot of money to buy inthe 18th century.5 Prescriptivism still exists today.6 According to descriptivists it is pointless to try to stop language change.7 Descriptivism only appeared after the 18th century.8 Both descriptivists and prescriptivists have been misrepresented.Questions 9-12Complete the summary using the list of words, A-I, below.Write the correct letter, A-I, in boxes 9-12 on your answer sheet.The language debateAccording to 9______, there is only one correct form of language. Linguists who take this approach to language place great importance on grammatical 10 ______.Conversely, the view of 11 ______, such as Joseph Priestly, is that grammar should be based on 12 ______.A descriptivistsB language expertsC popular speechD formal languageE evaluationF rulesG modern linguists H prescriptivists I changeQuestion 13Choose the correct letter, A, B, C or D.Write the correct letter in box 13 on your answer sheet.What is the writer’s purpose in Reading Passage 1?A. to argue in favour of a particular approach to writing dictionaries and grammar booksB. to present a historical account of differing views of languageC. to describe the differences between spoken and written languageD. to show how a certain view of language has been discreditedREADING PASSAGE 2You should spend about 20 minutes on Questions 14-26, which are based on Reading Passage 2 below.Tidal PowerUndersea turbines which produce electricity from the tides are set to become an important source of renewable energy for Britain. It is still too early to predict the extent of the impact they may have, but all the signs are that they will play a significant role in the futureA. Operating on the same principle as wind turbines, the power in sea turbines comes from tidal currents which turn blades similar to ships’ propellers, but, unlike wind, the tid es are predictable and the power input is constant. The technology raises the prospect of Britain becoming self-sufficient in renewable energy and drastically reducing its carbon dioxide emissions. If tide, wind and wave power are all developed, Britain would be able to close gas, coal and nuclear power plants and export renewable power to other parts of Europe. Unlike wind power, which Britain originally developed and then abandoned for 20 years allowing the Dutch to make it a major industry, undersea turbines could become a big export earner to island nations such as Japan and New Zealand.B. Tidal sites have already been identified that will produce one sixth or more of the UK’s power —and at prices competitive with modern gas turbines and undercutting those of the already ailing nuclear industry. One site alone, the Pentland Firth, between Orkney and mainland Scotland, could produce 10% of the country’s electricity with banks of turbines under the sea,and another at Alderney in the Channel Islands three times the 1,200 megawatts of Britain’s largest and newest nuclear plant, Sizewell B, in Suffolk. Other sites identified include the Bristol Channel and the west coast of Scotland, particularly the channel between Campbeltown and Northern Ireland.C. Work on designs for the new turbine blades and sites are well advanced at the University of Southampton’s sustainable energy research group. The first station is expected to be installed off Lynmouth in Devon shortly to test the technology in a venture jointly funded by the department of Trade and Industry and the European Union. AbuBakr Bahaj, in charge of the Southampton research, said: ‘The prospects for energy from tidal currents are far better than from wind because the flows of water are predictable and constant. The technology for dealing with the hostile saline environment under the sea has been developed in the North Sea oil industry and much is already known about turbine blade design, because of wind power and ship propellers. There are a few technical difficulties, but I believe in the next five to ten years we will be installing commercial marine turbine farms.’ Southampton has been awarded ￡215,000 over three years to develop the turbines and is working with Marine Current Turbines, a subsidiary of IT power, on the Lynmouth project. EU research has now identified 106 potential sites for tidal power, 80% round the coasts of Britain. The best sites are between islands or around heavily indented coasts where there are strong tidal currents.D. A marine turbine blade needs to be only one third of the size of wind generator to produce three times as much power. The blades will be about 20 metres in diameter, so around 30 metres of water is required. Unlike wind power, there are unlikelyto be environmental objections. Fish and other creatures are thought unlikely to be at risk from the relatively slow-turning blades. Each turbine will be mounted on a tower which will connect to the national power supply grid via underwater cables. The towers will stick out of the water and be lit, to warn shipping, and also be designed to be lifted out of the water for maintenance and to clean seaweed from the blades.E. Dr Bahaj has done most work on the Alderney site, where there are powerful currents. The single undersea turbine farm would produce far more power than needed for the Channel Islands and most would be fed into the French Grid and be re-imported into Britain via the cable under the Channel.F. One technical difficulty is cavitation, where low pressure behind a turning blade causes air bubbles. These can cause vibration and damage the blades of the turbines. Dr Bahaj said: ‘We have to test a number of blade types to avoid this happening or at least make sure it does not damage the turbines or reduce performance. Another slight concern is submerged debris floating into the blades. So far we do not know how much of a problem it might be. We will have to make the turbines robust because the sea is a hostile environment, but all the signs that we can do it are good.’Questions 14-17Reading Passage 2 has six paragraphs, A-F.Which paragraph contains the following information?Write the correct letter, A-F, in boxes 14-17 on your answer sheet.NB You may use any letter more than once.14 the location of the first test site15 a way of bringing the power produced on one site backinto Britain16 a reference to a previous attempt by Britain to find an alternative source of energy17 mention of the possibility of applying technology from another industryQuestions 18-22Choose FIVE letters, A-J.Write the correct letters in boxes 18-22 on your answer sheet.Which FIVE of the following claims about tidal power are made by the writer?A It is a more reliable source of energy than wind power.B It would replace all other forms of energy in Britain.C Its introduction has come as a result of public pressure.D It would cut down on air pollution.E It could contribute to the closure of many existing power stations in Britain.F It could be a means of increasing national income.G It could face a lot of resistance from other fuel industries.H It could be sold more cheaply than any other type of fuel.I It could compensate for the shortage of inland sites for energy production.J It is best produced in the vicinity of coastlines with particular features.Questions 23-26Label the diagram below.Choose NO MORE THAN TWO WORDS from the passage for each answer.Write your answers in boxes 23-26 on your answer sheet.An Undersea TurbineREADING PASSAGE 3You should spend about 20 minutes on Questions 27-40, which are based on Reading Passage 3 below.Information theory-the big ideaInformation theory lies at the heart of everything —from DVD players and the genetic code of DNA to the physics of the universe at its most fundamental. It has been central to the development of the science of communication, which enables data to be sent electronically and has therefore had a major impact on our livesA. In April 2002 an event took place which demonstrated one of the many applications of information theory. The space probe, Voyager I, launched in 1997, had sent back spectacular images of Jupiter and Saturn and then soared out of the Solar System on a one-way mission to the stars. After 25 years of exposure to the freezing temperatures of deep space, the probe was beginning to show its age. Sensors and circuits were on the brink of failing and NASA experts realized that they had to do something or lose contact with their probe forever. The solution was to get a message to Voyager I to instruct it to use spares to change the failing parts. With the probe 12 billion kilometers from Earth, this was not an easy task. By means of a radio dish belonging to NASA’s Deep Space Network, the message was sent out into the depths of space. Even travelling at the speed of light, it took over 11 hours to reach its target, far beyond the orbit of Pluto. Yet, incredibly, the little probe managed to hear the faint call from its home planet, and successfully made the switchover.B. It was the longest-distance repair job in history, and a triumph for the NASA engineers. But it also highlighted the astonishing power of the techniques developed by American communications engineer Claude Shannon, who had died just ayear earlier. Born in 1916 in Petoskey, Michigan, Shannon showed an early talent for maths and for building gadgets, and made breakthroughs in the foundations of computer technology when still a student. While at Bell Laboratories, Shannon developed information theory, but shunned the resulting acclaim. In the 1940s, he single-handedly created an entire science of communication which has since inveigled its way into a host of applications, from DVDs to satellite communications to bar codes — any area, in short, where data has to be conveyed rapidly yet accurately.C. This all seems light years away from the down-to-earth uses Shannon originally had for his work, which began when he was a 22-year-old graduate engineering student at the prestigious Massachusetts Institute of Technology in 1939. He set out with an apparently simple aim: to pin down the precise meaning of the concept of ‘information’. The most basic form of information, Shannon argued, is whether something is true or false —which can be captured in the binary unit, or ‘bit’, of the form 1 or 0. Having identified this fundamental unit, Shannon set about defining otherwise vague ideas about information and how to transmit it from place to place. In the process he discovered something surprising: it is always possible to guarantee information will get through random interference —‘noise’ — intact.D. Noise usually means unwanted sounds which interfere with genuine information. Information theory generalses this idea via theorems that capture the effects of noise with mathematical precision. In particular, Shannon showed that noise sets a limit on the rate at which information can pass along communication channels while remaining error-free. This ratedepends on the relative strengths of the signal and noise travelling down the communication channel, and on its capacity (its ‘bandwidth’). The resulting limit, given in units of bits per second, is the absolute maximum rate of error-free communication given singal strength and noise leve. The trick, Shannon showed, is to find ways of packaging up —‘coding’ — information to cope with the ravages of noise, while staying within the information-carrying capacity —‘bandwidth’ — of the communication system being used.E. Over the years scientists have devised many such coding methods, and they have proved crucial in many technological feats. The Voyager spacecraft transmitted data using codes which added one extra bit for every single bit of information; the result was an error rate of just one bit in 10,000 — and stunningly clear pictures of the planets. Other codes have become part of everyday life — such as the Universal Product Code, or bar code, which uses a simple error-detecting system that ensures supermarket check-out lasers can read the price even on, say, a crumpled bag of crisps. As recently as 1993, engineers made a major breakthrough by discovering so-called turbo codes —which come very close to Shannon’s ultimate limit for the maximum rate that data can be transmitted reliably, and now play a key role in the mobile videophone revolution.F. Shannon also laid the foundations of more efficient ways of storing information, by stripping out superfluous (‘redundant’) bits from data which contributed little real information. As mobile phone text messages like ‘I CN C U’ show, it is often possible to leave out a lot of data without losing much meaning. As with error correction, however, there’s a limit beyond which messages become too ambiguous. Shannonshowed how to calculate this limit, opening the way to the design of compression methods that cram maximum information into the minimum space.Questions 27-32Reading Passage 3 has six paragraphs, A-F.Which paragraph contains the following information?Write the correct letter, A-F, in boxes 27-32 on your answer sheet.27 an explanation of the factors affecting the transmission of information28 an example of how unnecessary information can be omitted29 a reference to Shannon’s attitude to fame30 details of a machine capable of interpreting incomplete information31 a detailed account of an incident involving information theory32 a reference to what Shannon initially intended to achieve in his researchQuestions 33-37Complete the notes below.Choose NO MORE THAN TWO WORDS form the passage for each answer.Write your answers in boxes 33-37 on your answer sheet.The Voyager 1 Space ProbeThe probe transmitted pictures of both 33______ and ______, then left the 34 ______.The freezing temperatures were found to have a negative effect on parts of the space probe.Scientists feared that both the 35 ______ and ______ wereabout to stop working.The only hope was to tell the probe to replace them with 36 ______ —but distance made communication with the probe difficult.A 37 ______ was used to transmit the message at the speed of light.The message was picked up by the probe and the switchover took place.Questions 38-40Do the following statements agree with the information given in Reading Passge 3?In boxes 38-40 on your answer sheet, writeTRUE if the statement agrees with the informationFALSE if the statement contradicts the informationNOT GIVEN if there is no information on this38 The concept of describing something as true or false was the starting point for Shannon in his attempts to send messages over distances.39 The amount of information that can be sent in a given time period is determined with reference to the signal strength and noise level.40 Products have now been developed which can convey more information than Shannon had anticipated as possible.剑桥雅思阅读9原文参考译文(test3)PASSAGE 1 参考译文：对语言的态度对于语言进行系统、客观的研究并不容易。

Test 1 Passage 2Question 14答案：I关键词：suggestion, in the future /would help定位原文: I 段最后1句“Bringing these barriers down would help…”解题思路: 首先看到题干中有明确的时间词“在未来”。
根据段意，可以判定应该是文章的最后一段。
之后看题干中的定位词suggestion表示建议，在文章结尾部分的最后一句话，可以清楚地找到它是作者对于提高贸易的一个建议，完全对应。
Question 15答案： F关键词：electronic delivery/transmitting...over telephone定位原文: F段第3句“...simply by transmitting…”解题思路: 题干中提到电子式的传递，很容易跟文章关于信息产业的F段挂钩，之后再细读本段第二句话就可以找到与题干相对应的 transmitting...over telephone。
因此，答案是F段。
Question 16答案： E关键词：similar cost Abroad, local/ Singapore, domestic定位原文: E段倒数第2句“… manufacturers in Japan or Texas…”解题思路: 题干是说“无论是国际还是国内的，在运输货物环节的相近成本。
”也就是说国内的运输和国际的运输成本基本相同，间接表明国际运输成本比较低。
而文章中此句话的意思是“即使从新加坡进口磁盘驱动器而不是在国内市场购买，日本或美国得克萨斯州的计算机制造商们也不会面对花费高出很多的运费账单”。
可以看出制造商们不用花费很高的运费，正好跟题干相应。

语言点：(1)句型分析逗号之前的部分为the instant引导的时间状语从句，在instant后面若加上when应该就不难理解了。

It is generally believed that large numbers of people were needed to build the pyramids.参考译文人们一般认为修建金字塔需要大量的人力。
定位词large numbers of people, build the pyramids解题关键believed字文中对应第一段：点The conventional picture is that tens of thousands of slaves dragged stones on the sledges.此题通过定位词可以迅速定位至首段第二句话，题干为对文章定位句的概括性改写，分析如下：generally believed—conventional picture, large numbers of people—tensof thousands of slaves因此答案很明显应该是TRUE。
2. Clemmons found a strange hieroglyph on the wall of an Egyptian monument.参考译文Clemmons在一个埃及古迹的墙面上发现了一种奇怪的象形文字。
定位词hieroglyph, Egyptian monument解题关键字found文中对应点第二段：While perusing a book on the monuments of Egypt, she noticed a hieroglyph that showed a row of men standing in odd postures.此题定位词在文中原词出现，可以快速定位。
文中定位句指出Clemmons是在一本关于埃及古迹的书中读到的象形文字信息，而题目却说她在一座埃及古迹的墙上发现了象形文字，显然题目与文章相悖，因此此题答案为FALSE。
3. Gharib had previously done experiments on bird flight.参考译文Gharib之前做过鸟类飞行的实验。
