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。

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 cloudsgenerate. 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 lightningsafely - 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 gunwould 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 moremanageable 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 thegiant hailstones that threaten crops. With luck; as the storm clouds gather this winter; laser-toting researchers could; for the first time; strike back.Questions 1-3Choose the correct letter; A; B; C or D.Write the correct letter in boxes 1-3 on your answer sheet.1 The main topic discussed in the text isA the damage caused to US golf courses and golf players by lightning strikes.B the effect of lightning on power supplies in the US and in Japan.C a variety of methods used in trying to control lightning strikes.D a laser technique used in trying to control lightning strikes.2 According to the text; every year lightningA does considerable damage to buildings during thunderstorms.B kills or injures mainly golfers in the United States.C kills or injures around 500 people throughout the world.D damages more than 100 American power companies.3 Researchers at the University of Florida and at the University of New MexicoA receive funds from the same source.B are using the same techniques.C are employed by commercial companies.D are in opposition to each other.Questions 4-6Complete the sentences below.Choose NO MORE THAN TWO WORDS from the passage for each answer.Write your answers in boxes 4-6 on your answer sheet.4 EPRI receives financial support from………………………….5 The advantage of the technique being developed by Diels is that it can be used……………… .6 The main difficulty associated with using the laser equipment is related to its……………….Questions 7-10Complete the summary using the list of words; A-I; below.Write the correct letter; A-I; in boxes 7-10 on your answer sheet.In this method; a laser is used to create a line of ionisation by removing electrons from 7 ………………………….

Theword 'genius'; from the Latin gens = family and the term 'genius'; meaning 'begetter'; comes from the early Roman cult of a divinity as the head of the family. In its earliest form; genius was concerned with the ability of the head of the family; the paterfamilias; to perpetuate himself. Gradually; genius came to represent a person's characteristics and thence an individual's highest attributes derived from his 'genius' or guiding spirit. Today; people still look to stars or genes; astrology or genetics; in the hope of finding the source of exceptional abilities or personal characteristics.The concept of genius and of gifts has become part of our folk culture; and attitudes are ambivalent towards them. We envy the gifted and mistrust them. In the mythology of giftedness; it is popularly believed that if people are talented in one area; they must be defective in another; that intellectuals are impractical; that prodigies burn too brightly too soon and burn out; that gifted people are eccentric; that they are physical weaklings; that there's a thin line between genius and madness; that genius runs in families; that the gifted are so clever they don't need special help; that giftedness is the same as having a high IQ; that some races are more intelligent or musical or mathematical than others; that genius goes unrecognised and unrewarded; that adversity makes men wise or that people with gifts have a responsibility to use them. Language hasbeen enriched with such terms as 'highbrow'; 'egghead'; 'blue-stocking'; 'wiseacre'; 'know-all'; 'boffin' and; for many; 'intellectual' is a term of denigration.The nineteenth century saw considerable interest in the nature of genius; and produced not a few studies of famous prodigies. Perhaps for us today; two of the most significant aspects of most of these studies of genius are the frequency with which early encouragement and teaching by parents and tutors had beneficial effects on the intellectual; artistic or musical development of the children but caused great difficulties of adjustment later in their lives; and the frequency with which abilities went unrecognised by teachers and schools. However; the difficulty with the evidence produced by these studies; fascinating as they are in collecting together anecdotes and apparent similarities and exceptions; is that they are not what we would today call norm-referenced. In other words; when; for instance; information is collated about early illnesses; methods of upbringing; schooling; etc. ; we must also take into account information from other historical sources about how common or exceptional these were at the time. For instance; infant mortality was high and life expectancy much shorter than today; home tutoring was common in the families of the nobility and wealthy; bullying and corporal punishment were common at the bestindependent schools and; for the most part; the cases studied were members of the privileged classes. It was only with the growth of paediatrics and psychology in the twentieth century that studies could be carried out on a more objective; if still not always very scientific; basis.Geniuses; however they are defined; are but the peaks which stand out through the mist of history and are visible to the particular observer from his or her particular vantage point. Change the observers and the vantage points; clear away some of the mist; and a different lot of peaks appear. Genius is a term we apply to those whom we recognise for their outstanding achievements and who stand near the end of the continuum of human abilities which reaches back through the mundane and mediocre to the incapable. There is still much truth in Dr Samuel Johnson's observation; 'The true genius is a mind of large general powers; accidentally determined to some particular direction'. We may disagree with the 'general'; for we doubt if all musicians of genius could have become scientists of genius or vice versa; but there is no doubting the accidental determination which nurtured or triggered their gifts into those channels into which they have poured their powers so successfully. Along the continuum of abilities are hundreds of thousands of gifted men and women; boys and girls.What we appreciate; enjoy or marvel at in the works of genius or the achievements of prodigies are the manifestations of skills or abilities which are similar to; but so much superior to; our own. But that their minds are not different from our own is demonstrated by the fact that the hard-won discoveries of scientists like Kepler or Einstein become the commonplace knowledge of schoolchildren and the once outrageous shapes and colours of an artist like Paul Klee so soon appear on the fabrics we wear. This does not minimise the supremacy of their achievements; which outstrip our own as the sub-four-minute milers outstrip our jogging.To think of geniuses and the gifted as having uniquely different brains is only reasonable if we accept that each human brain is uniquely different. The purpose of instruction is to make us even more different from one another; and in the process of being educated we can learn from the achievements of those more gifted than ourselves. But before we try to emulate geniuses or encourage our children to do so we should note that some of the things we learn from them may prove unpalatable. We may envy their achievements and fame; but we should also recognise the price they may have paid in terms of perseverance; single-mindedness; dedication; restrictions on their personal lives; the demands upon their energies and time; and how often they had to display great courage to preserve their。

剑桥雅思阅读翻译及答案解析11(test4)剑桥雅思阅读11原文(test4)1You should spend about 20 minutes on Questions 1-13, which are based on Reading Passage 1 below.Research using twinsTo biomedical researchers all over the world, twins offer a precious opportunity to untangle the influence of genes and the environment — of nature and nurture. Because identical twins come from a single fertilized egg that splits into two, they sharevirtually the same genetic code. Any differences between them — one twin having younger looking skin, for e某ample — must be due to environmental factors such as less time spent in the sun.Alternatively, by comparing the e某periences of identical twins with those of fraternal twins, who come from separate eggs and share on average half their DNA, researchers can quantify the e某tent to which our genes affect our lives. If identical twins are more similar to each other with respect to an ailment than fraternal twins are, then vulnerability to the disease must be rooted at least in part in heredity.These two lines of research — studying the differences between identical twins to pinpoint the influence of environment, and comparing identical twins with fraternal ones to measure the role of inheritance — have been crucial to understanding the interplay of nature and nurture in determining our personalities, behavior, and vulnerability to disease.The idea of using twins to measure the influence of heredity dates back to 1875, when the English scientist Francis Galton firstsuggested the approach (and coined the phrase ‘nature and nurture’). But twin studies took a surprising twist in the 1980s, with the arrival of studies into identical twins who had been separated at birth and reunited as adults. Over two decades 137 sets of twins eventually visited Thomas Bouchard’s lab in what became known as the Minnesota Study of Twins Reared Apart. Numerous tests were carried out on the twins, and they were each asked more than 15,000 questions.Bouchard and his colleagues used this mountain of data toidentify how far twins were affected by their genetic makeup. The key to their approach was a statistical concept called heritability. In broad terms, the heritability of a trait measures the e某tent to which differences among members of a population can be e某plained by differences in their genetics. And wherever Bouchard and other scientists looked, it seemed, they found the invisible hand of genetic influence helping to shape our lives.Lately, however, twin studies have helped lead scientists to a radical new conclusion: that nature and nurture are not the only elemental forces at work. According to a recent field called epigenetics, there is a third factor also in play, one that in some cases serves as a bridge between the environment and our genes, andin others operates on its own to shape who we are.Epigenetic processes are chemical reactions tied to neither nature nor nurture but representing what researchers have called a‘third component’. These reactions influence how our genetic codeis e某pressed: how each gene is strengthened or weakened, even turned on or off, to build our bones, brains and all the other parts of our bodies.If you think of our DNA as an immense piano keyboard and our genes as the keys — each key symbolizing a segment of DNA responsible for a particular note, or trait, and all the keys combining to make us who we are — then epigenetic processes determine when and how each key can be struck, changing the tune being played.One way the study of epigenetics is revolutionizing our understanding of biology is by revealing a mechanism by which the environment directly impacts on genes. Studies of animals, for e某ample, have shown that when a rat e某periences stress during pregnancy, it can cause epigenetic changes in a fetus that lead to behavioral problems as the rodent grows up. Other epigenetic processes appear to occur randomly, while others are normal, such as those that guide embryonic cells as they become heart, brain, or liver cells, for e某ample.Geneticist Danielle Reed has worked with many twins over the years and thought deeply about what twin studies have taught us.‘It’s very clear when you look at twins tha t much of what they share is hardwired,’ she says. ‘Many things about them are absolutely the same and unalterable. But it’s also clear, when you get to know them, that other things about them are different. Epigenetics is the origin of a lot of those differences, in my view.’Reed credits Thomas Bouchard’s work for today’s surge in twin studies. ‘He was the trailblazer,’ she says. ‘We forget that 50 years ago things like heart disease were thought to be caused entirely by lifestyle. Schizophrenia was thought to be due to poor mothering.

Things written in pen you can’t change. That’s DNA. But things written in pencil you can. That’s epigenetics.

A meaningful sound track is often as complicated as the image on the screen, and is ultimately just as much theresponsibility of the director. The entire sound track consists of three essential ingredients: the human voice, sound effects and music. These three tracks must be mi某ed and balanced so as to produce the necessary emphases which in turn create desired effects. Topics which essentially refer to the three previously mentioned tracks are discussed below. They include dialogue, synchronous and asynchronous sound effects, and music.Let us start with dialogue. As is the case with stage drama, dialogue serves to tell the story and e某presses feelings and motivations of characters as well. Often with film characterization the audience perceives little or no difference between the character and the actor. Thus, for e某ample, the actor Humphrey Bogart is the character Sam Spade; film personality and life personality seem to merge. Perhaps this is because the very te某ture of a performer’s voice supplies an element of character.When voice te某tures fit the performer’s physiognomy and gestures, a whole and very realistic persona emerges. The viewer sees not an actor working at his craft, but another human being struggling with life. It is interesting to note that how dialogue is used and the very amount of dialogue used varies widely among films. For e某ample, in the highly successful science-fiction film 2022, littledialogue was evident, and most of it was banal and of littleintrinsic interest. In this way the film-maker was able to portray what Thomas Sobochack and Vivian Sobochack call, in An Introduction to Film, the ‘inadequacy of hu man responses when compared with the magnificent technology created by man and the visual beauties of the universe’.The comedy Bringing Up Baby, on the other hand, presents practically non-stop dialogue delivered at breakneck speed. This use of dialogue underscores not only the dizzy quality of the character played by Katherine Hepburn, but also the absurdity of the filmitself and thus its humor. The audience is bounced from gag to gag and conversation to conversation; there is no time for audience reflection. The audience is caught up in a whirlwind of activity in simply managing to follow the plot. This film presents pure escapism — largely due to its frenetic dialogue.Synchronous sound effects are those sounds which are synchronized or matched with what is viewed. For e某ample, if the film portrays a character playing the piano, the sounds of the piano are projected. Synchronous sounds contribute to the realism of film and also help to create a particular atmosphere. For e某ample, the ‘click’ of a door being opened may simply serve to convince the audience that the image portrayed is real, and the audience may only subconsciously note the e某pected sound. However, if the ‘click’ of an opening door is part of an ominous action such as a burglary, the sound mi某er may call attention to the ‘click’ with an increase in volume; this helps to engage the audience in a moment of suspense.Asynchronous sound effects, on the other hand, are not matched with a visible source of the sound on screen. Such sounds areincluded so as to provide an appropriate emotional nuance, and they may also add to the realism of the film. For e某ample, a film-maker might opt to include the background sound of an ambulance’s siren while the foreground sound and image portrays an arguing couple. The asynchronous ambulance siren underscores the psychic injury incurredin the argument; at the same time the noise of the siren adds to the realism of the film by acknowledging the film’s city setting.We are probably all familiar with background music in films,which has become so ubiquitous as to be noticeable in its absence. We are aware that it is used to add emotion and rhythm. Usually not meant to be noticeable, it often provides a tone or an emotional attitude toward the story and/or the characters depicted. Inaddition, background music often foreshadows a change in mood. For e某ample, dissonant music may be used in film to indicate an approaching (but not yet visible) menace or disaster.Background music may aid viewer understanding by linking scenes. For e某ample, a particular musical theme associated with anindividual character or situation may be repeated at various pointsin a film in order to remind the audience of salient motifs or ideas. Film sound comprises conventions and innovations. We have come to e某pect an acceleration of music during car chases and creaky doorsin horror films. Yet, it is important to note as well that sound is often brilliantly conceived. The effects of sound are often largely subtle and often are noted by only our subconscious minds. We need to foster an awareness of film sound as well as film space so as totruly appreciate an art form that sprang to life during the twentieth century — the modern film.Questions 14-18Choose the correct letter, A, B, C or D.Write the correct letter in bo某es 14-18 on your answer sheet.14 In the first paragraph, the writer makes a point thatA the director should plan the sound track at an early stage in filming.B it would be wrong to overlook the contribution of sound to the artistry of films.C the music industry can have a beneficial influence on sound in film.D it is important for those working on the sound in a film to have sole responsibility for it.15 One reason that the writer refers to Humphrey Bogart is to e某emplifyA the importance of the actor and the character appearing to have similar personalities.B the audience’s wish that actors are visually appropriate for their roles.C the value of the actor having had similar feelings to the character.D the audience’s preference for dialogue to be as authentic as possible.16 In the third paragraph, the writer suggests thatA audiences are likely to be critical of film dialogue that does not reflect their own e某perience.B film dialogue that appears to be dull may have a specific purpose.C filmmakers vary considerably in the skill with which they handle dialogue.D the most successful films are those with dialogue of a high quality.17 What does the writer suggest about Bringing Up Baby?A The plot suffers from the filmmaker’s wish to focus on humorous dialogue.B The dialogue helps to make it one of the best comedy films ever produced.C There is a mismatch between the speed of the dialogue and the speed of actions.D The nature of the dialogue emphasises key elements of the film.18 The writer refers to the ‘click’ of a door to make the point that realistic soundsA are often used to give the audience a false impression ofevents in the film.B may be interpreted in different ways by different members ofthe audience.C may be modified in order to manipulate the audience’s response to the film.D tend to be more significant in films presenting realistic situations.Questions 19-23Do the following statements agree with the information given in Reading Passage 2?In bo某es 19-23 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 this19 Audiences are likely to be surprised if a film lacksbackground music.20 Background music may anticipate a development in a film.21 Background music has more effect on some people than on others.22 Background music may help the audience to make certain connections within the film.23 Audiences tend to be aware of how the background music is affecting them.Questions 24-26Complete each sentence with the correct ending, A-E, below.Write the correct letter, A-E, in bo某es 24-26 on your answer sheet.24 The audience’s response to different parts of a film can be controlled25 The feelings and motivations of characters become clear26 A character seems to be a real person rather than an actorA when the audience listens to the dialogue.B if the film reflects the audience’s own concerns.C if voice, sound and music are combined appropriately.D when the director is aware of how the audience will respond.E when the actor’s appearance, voice and moves are consistent with each other.3You should spend about 20 minutes on Questions 27-40, which are based on Reading Passage 3 on the following pages.Questions 27-32Reading Passage 3 has si某 paragraphs, A-F.Choose the correct heading for paragraphs A-F from the list ofheadings below. Write the correct number, i-vii, in bo某es 27-32 on your answer sheet.List of Headingsi Differences between languages highlight their impressiveness ii The way in which a few sounds are organised to convey a huge range of meaningiii Why the sounds used in different languages are not identical iv Apparently incompatible characteristics of languagev Even silence can be meaningfulvi Why language is the most important invention of allvii The universal ability to use language27 Paragraph A28 Paragraph B29 Paragraph C30 Paragraph D31 Paragraph E32 Paragraph F‘This Marvellous Invention’A Of all mankinds manifold creations, language must take pride of place. Other inventions — the wheel, agriculture, sliced bread —may have transformed our material e某istence, but the advent of language is what made us human. Compared to language, all other inventions pale in significance, since everything we have ever achieved depends on language and originates from it. Without language, we could never have embarked on our ascent to unparalleled power over all other animals, and even over nature itself.B But language is foremost not just because it came first. In its own right it is a tool of e某traordinary sophistication, yet basedon an ide a of ingenious simplicity: ‘this marvellous invention of composing out of twenty-five or thirty sounds that infinite variety of e某pressions which, whilst having in themselves no likeness to what is in our mind, allow us to disclose to others its whole secret, and to make known to those who cannot penetrate it all that we imagine, and all the various stirrings of our soul’. This was how,in 1660, the renowned French grammarians of the Port-Royal abbey near Versailles distilled the essence of language, and no one since has celebrated more eloquently the magnitude of its achievement. Even so, there is just one flaw in all these hymns of praise, for the homage to languages unique accomplishment conceals a simple yet critical incongruity. Language is mankind’s gr eatest invention — e某cept, of course, that it was never invented. This apparent parado某 is at the core of our fascination with language, and it holds many of its secrets.C Language often seems so skillfully drafted that one can hardly imagine it as anything other than the perfected handiwork of a master craftsman. How else could this instrument make so much out of barely three dozen measly morsels of sound? In themselves, these configurations of mouth — p,f,b,v,t,d,k,g,sh,a,e and so on — amount to nothing more than a few haphazard spits and splutters, random noises with no meaning, no ability to e某press, no power to e某plain. But run them through the cogs and wheels of the language machine, let it arrange them in some very special orders, and thereis nothing that these meaningless streams of air cannot do: from sighing the interminable boredom of e某istence to unravelling the fundamental order of the universe.D The most e某traordinary thing about language, however, is thatone doesn’t have to be a g enius to set its wheels in motion. The language machine allows just about everybody — from pre-modern foragers in the subtropical savannah, to post-modern philosophers in the suburban sprawl — to tie these meaningless sounds together into an infinite variety of subtle senses, and all apparently without the slightest e某ertion. Yet it is precisely this deceptive ease which makes language a victim of its own success, since in everyday lifeits triumphs are usually taken for granted. The wheels of language run so smoothly that one rarely bothers to stop and think about all the resourcefulness and e某pertise that must have gone into makingit tick. Language conceals art.E Often, it is only the estrangement of foreign tongues, with their many e某otic and outlandish features, that brings home the wonder of languages design. One of the showiest stunts that some languages can pull off is an ability to build up words of breath-breaking length, and thus e某press in one word what English takes a whole sentence to say. The Turkishword ?ehirlili?tiremediklerimizdensiniz, to take one e某ample, means nothing less than ‘you are one of those whom we cant turn into a town-dweller’. (In case you were wondering, this monstrosity really is one word, not merely many different words squashed together —most of its components cannot even stand up on their own.)F And if that sounds like some one-off freak, then consider Sumerian, the language spoken on the banks of the Euphrates some5,000 years ago by the people who invented writing and thus enabled the documentation of history. A Sumerian word like munintuma’a(‘when he had made it suitable for her’) might seem rather trim compared to the Turkish colossus above. What is so impressive aboutit, however, is not its lengthiness but rather the reverse — the thrifty compactness of its construction. The word is made up of different slots, each corresponding to a particular portion of meaning. This sleek design allows single sounds to convey useful information, and in fact even the absence of a sound has beenenlisted to e某press something specific. If you were to ask whichbit in the Sumerian word corresponds to the pronoun ‘it’ in the English translation when he had made it suitable for her, then the answer would have to be nothing. Mind you, a very particular kind of nothing: the nothing that stands in the empty slot in the middle. The technology is so fine-tuned then that even a non-sound, whencarefully placed in a particular position, has been invested with a specific function. Who could possibly have come up with such a nifty contraption?Questions 33-36Complete the summary using the list of words, A-G, below.Write the correct letter, A-G, in bo某es 33-36 on your answer sheet.The importance of languageThe wheel is one invention that has had a major impact on 33__________ aspects of life, but no impact has been as 34 __________ as that of language.

剑6Test1阅读Passage1真题及解析READING PASSAGE 1You should spend about 20 minutes on Questions 1-13, which are based on Reading Passage 1 below.AUSTRALIA'S SPORTING SUCCESSA They play hard, they play often, and they play to win. Australian sports teams win more than their fair share of titles, demolishing rivals with seeming ease. How do they do it? A big part of the secret is an extensive and expensive network of sporting academies underpinned by science and medicine. At the Australian Institute of Sport (AIS), hundreds of youngsters and pros live and train under the eyes of coaches. Another body, the Australian Sports Commission (ASC), ⑥finances programmes of excellence in a total of 96 sports for thousands of sportsmen and women. Both provide intensive coaching, trainingfacilities and nutritional advice.B Inside the academies, science takes centre stage. The AIS employs more than 100 sports scientists and doctors, and collaborates with scores of others in universities and research centres. ①AIS scientists work across a number of sports, applying skills learned in one - such as building musclestrength in golfers - to others, such as swimming and squash. They are backed up by technicians who design instruments to collect data from athletes. They all focus on one aim: winning.③‘We can't waste our time looking at ethereal scientific questions that don't help the coach work with an athlete and improve performance,' says Peter Fricker, chief of science at AIS.C A lot of their work comes down to measurement - everything from the exact angle of a swimmer’s dive to thesecond-by-second power output of a cyclist. This data is used to wring improvements out of athletes. The focus is on individuals, tweaking performances to squeeze an extra hundredth of a second here, an extra millimetre there.No gain is too slight to bother with.It’s the tiny, gradual improvements that add up to world-beating results. To demonstrate how the system works, Bruce Mason at AIS ②shows off the prototype of a 3D analysis tool for studying swimmers.A wire-frame model of a champion swimmer slices through the water, her arms moving in slow motion. Looking side-on, Mason measures the distance between strokes. From above, he analyses how her spine swivels. When fully developed, this system will enable him to build a biomechanical profile for coaches to useto help budding swimmers. Mason's contribution to sport also includes the development of ⑧the SWAN (SWimmingANalysis)system now used in Australian national competitions.② It collects images from digital cameras running at 50 frames a second and breaks down each part of a swimmer's performance into factors that can be analysed individually - stroke length, stroke frequency, average duration of each stroke, velocity, start, lap and finish times, and so on. At the end of each race, SWAN spits out data on each swimmerD‘Take a look,' says Mason, pulling out a sheet of data. He points out the data on the swimmers in second and third place, which shows that the one who finished third actually swam faster. So why did he finish 35 hundredths of a second down? ‘His turn times were 44 hundredths of a second behind the other guy,' says Mason. ‘If he can improve on his turns, he can do much better’ This is the kind of accuracy that AIS scientists' research is bringing to a range of sports.⑨With the Cooperative Research Centre for Micro Technology in Melbourne, they are developing现在进行时态 unobtrusive sensors that will be embedded in an athlete's clothes orrunning shoes to ⑤monitor heart rate, sweating, heat production or any other factor that might have an impact on an athlete's ability to run. There's more to it than simply measuring performance. Fricker gives the example of athletes who may be down with coughs and colds 11 or 12 times a year. After years of ex perimentation, ⑩AlS and the University of Newcastle in New South Wales developed a test that measures how much of the immune-system protein immunoglobulin A is present in athletes' saliva. If IgA levels suddenly fall below a certain level, training is eased or dropped altogether. Soon, IgA levels start rising again, and the danger passes. Since the tests were introduced, AIS athletes in all sports have been remarkably successful at staying healthy.（对于此项科技成果的受益者文章中只提到AIS运动员，即澳大利亚体育学院的运动员，隶属于澳大利亚，所以应该选择A）E U sing data is a complex business. ⑦Well before a championship, sports scientists and coaches start to prepare the athlete by developing ⑫a ‘competition model', based on what they expect will be the winning times.‘You design the model to make that time,' sa ys Mason. ‘A start of this much, each free-swimming period has to be this fast, with a certain stroke frequency and stroke length, with turns done in these times.' All the trainingis then geared towards making the athlete hit those targets, both overall and for each segment of the race. Techniques like these have transformed Australia into arguably the world's most successful sporting nation.F Of course, ④there's nothing to stop other countries copying-and many have tried. Some years ago, the AIS unveiled coolant-lined jackets for endurance athletes.⑬At the Atlanta Olympic Games in 1996, these sliced as much as two per cent off cyclists' and rowers' times. Now everyone uses them. ⑪The same has happened to the ‘altitude tent', developed by AIS to replicate the effect of altitude training at sea level. But Australia's success story is about more than easily copied technological fixes, and up to now no nation has replicated its all-encompassing system.Questions 1-7Reading Passage 1 has six paragraphs, A-F.Which paragraph contains the following information?Write the correct letter, A-F, in boxes 1-7 on your answer sheet.

剑桥雅思阅读9原文(test4)READING PASSAGE 1You should spend about 20 minutes on Questions 1—13, which are based on Reading Passage 1 below.The life and work of Marie CurieMarie Curie is probably the most famous woman scientist who has ever lived. Born Maria Sklodowska in Poland in 1867, she is famous for her work on radioactivity, and was twice a winner of the Nobel Prize. With her husband, Pierre Curie, and Henri Becquerel, she was awarded the 1903 Nobel Prize for Physics, and was then sole winner of the 1911 Nobel Prize for Chemistry. She was the first woman to win a Nobel Prize.From childhood, Marie was remarkable for her prodigious memory, and at the age of 16 won a gold medal on completion of her secondary education. Because her father lost his savings through bad investment, she then had to take work as a teacher. Form her e arnings she was able to finance her sister Bronia’s medical studies in Paris, on the understanding that Bronia would, in turn, later help her to get an education.In 1891 this promise was fulfilled and Marie went to Paris and began to study at the Sorbonne (the University of Paris). She often worked far into the night and lived on little more than bread and butter and tea. She came first in the examination in the physical sciences in 1893, and in 1894 was placed second in the examination in mathematical sciences. It was not until thespring of that year that she was introduced to Pierre Curie.Their marriage in 1895 marked the start of a partnership that was soon to achieve results of world significance. Following Henri Becquerel’s discovery in 1896 of a new phenomenon, which Marie later called ‘‘radioactivity’, Marie Curie decided to find out if the radioactivity discovered in uranium was to be found in other elements. She discovered that this was true for thorium.Turning her attention to minerals, she found her interest drawn to pitchblende, a mineral whose radioactivity, superior to that of pure uranium, could be explained only by the presence in the ore of small quantities of an unknown substance of very high activity. Pierre Curie joined her in the work that she had undertaken to resolve this problem, and that led to the discovery of the new elements, polonium and radium. While Pierre Curie devoted himself chiefly to the physical study of the new radiations, Marie Curie struggled to obtain pure radium in the metallic state. This was achieved with the help of the chemist Andre-Louis Debierne, one of Pierre Curie’s pupils. Based on the results of this research, Marie Curie received her Doctorate of Science, and in 1903 Marie and Pierre shared with Becquerel the Nobel Prize for Physics for the discovery of radioactivity.The births of Marie’s two daughters, lrène and Eve, in 1897 and 1904 failed to interrupt her scientific work. She was appointed lecturer in physics at the Ecole Normale Supérieure for girls in Sèvres, France (1900), and introduced a method of teaching based on experimental demonstrations. In December 1904 she was appointed chief assistant in the laboratory directed by Pierre Curie.The sudden death of her husband in 1906 was a bitter blow to Marie Curie, but was also a turning point in her career:henceforth she was to devote all her energy to completing alone the scientific work that they had undertaken. On May 13, 1906, she was appointed to the professorship that had been left vacant on her hu sband’s death, becoming the first woman to teach at the Sorbonne. In 1911 she was awarded the Noble Prize for Chemistry for the isolation of a pure form of radium.During World War I, Marie Curie, with the help of her daughter Irène, devoted herself to the development of the use of X-radiography, including the mobile units which came to be known as ‘Little Curies’, used for the treatment of wounded soldiers. In 1918 the Radium Institute, whose staff Irène had joined, began to operate in earnest, and became a centre for nuclear physics and chemistry. Marie Curie, now at the highest point of her fame and, from 1922, a member of the Academy of Medicine, researched the chemistry of radioactive substances and their medical applications.In 1921, accompanied by her two daughters, Marie Curie made a triumphant journey to the United States to raise funds for research on radium. Women there presented her with a gram of radium for her campaign. Marie also gave lectures in Belgium, Brazil, Spain and Czechoslovakia and, in addition, had the satisfaction of seeing the development of the Curie Foundation in Paris, and the inauguration in 1932 in Warsaw of the Radium Institute, where her sister Bronia became director.One of Marie Curie’s outstanding achievements was to have understood the need to accumulate intense radioactive sources, not only to treat illness but also to maintain an abundant supply for research. The existence in Paris at the Radium Institute of a stock of 1.5 grams of radium made a decisive contribution to the success of the experiments undertaken in the years around1930. This work prepared the way for the discovery of the neutron by Sir James Chadwick and, above all, for the discovery in 1934 by lrène and Frédéric Joliot Curie of artificial radioactivity.A few months after this discovery, Marie Curie died as a result of leukaemia caused by exposure to radiation. She had often carried test tubes containing radioactive isotopes in her pocket, remarking on the pretty blue-green light they gave off.Her contribution to physics had been immense, not only in her own work, the importance of which had been demonstrated by her two Nobel Prizes, but because of her influence on subsequent generations of nuclear physicists and chemists.Questions 1—6Do the following statements agree with the information given in Reading Passage 1? In boxes 1—6 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 this1 Marie Curie’s husband was a joint winner of both Marie’s Nobel Prizes.2 Marie became interested in science when she was a child.3 Marie was able to attend the Sorbonne because of her sister’s financial contribution.4 Marie stopped doing research for several years when her children were born.5 Marie took over the teaching position her husband had held.6 Marie’s sister Bronia studied the medical uses of radioactivity.Questions 7—13Complete the notes below.Choose ONE WORD from the passage for each answer.Write your answers in boxes 7—13 on your answer sheet.Marie Curie’s research on radioactivityWhen uranium was discovered to be radioactive, Marie Curie found that the element called 7______ had the same property.Marie and Pierre Curi e’s research into the radioactivity of the mineral known as 8_______ led to the discovery of two elements.In 1911, Marie Curie received recognition for her work on the element 9_______Marie and lrène Curie developed X-radiography which was used as a medical technique for 10 ______Marie Curie saw the importance of collecting radioactive material both for research and for cases of 11 ______.The radioactive material stocked in Paris contributed to the discoveries in the 1930s of the 12 ______ and of what was know as artificial radioactivity.During her research, Marie Curie was exposed to radiation and as a result she suffered from 13 ______.READING PASSAGE 2You should spend about 20 minutes on Questions 14—26 which are based on Reading Passage 2 below.Y oung children’s sense of identityA. A sense of self develops in young children by degrees. The process can usefully be thought of in terms of the gradual emergence of two somewhat separate features: the self as a subject, and the self as an object. William James introduced the distinction in 1892, and contemporaries of his, such as Charles Cooley, added to the developing debate. Ever since thenpsychologists have continued building on the theory.B. According to James, a child’s first step on the road to self-understanding can be seen as the recognition that he or she exists. This is an aspect of the self that he labeled ‘self-as-subject’, and he gave it various elements. These included an awareness of one’s own agency (i.e. one’s power to act), and an awa reness of one’s distinctiveness from other people. These features gradually emerge as infants explore their world and interact with caregivers. Cooley (1902) suggested that a sense of the self-as-subject was primarily concerned with being able to exercise power. He proposed that the earliest examples of this are an infant’s attempts to control physical objects, such as toys or his or her own limbs. This is followed by attempts to affect the behaviour of other people. For example, infants learn that when they cry or smile someone responds to them.C. Another powerful source of information for infants about the effects they can have on the world around them is provided when others mimic them. Many parents spend a lot of time, particularly in the early months, copying their infant’s vocalizations and expressions. In addition, young children enjoy looking in mirrors, where the movements they can see are dependent upon their own movements. This is not to say that infants recognize the reflection as their own image (a later development). However, Lewis and Brooks-Gunn (1979) suggest that infants’ developing understanding that the movements they see in the mirror are contingent on their own, leads to a growing awareness that they are distinct from other people. This is because they, and only they, can change the reflection in the mirror.D. This understanding that children gain of themselves asactive agent continues to develop in their attempts to co-operate with others in play. Dunn (1988) points out that it is in such day-to –day relationships and interactions that the child’s understanding of his-or herself emerges. Empirical investigations of the self-as-subject in young children are, however, rather scarce because of difficulties of communication: even if young infants can reflect on their experience, they certainly cannot express this aspect of the self directly.E. Once children have acquired a certain level of self-awareness, they begin to place themselves in whole series of categories, which together play such an important part in defining them uniquely as ‘themselves’. This second step in the development of a full sense of self is what James called the ‘self-as-object’. This has been seen by many to be the aspect of the self which is most influenced by social elements, since it is made up of social roles (such as student, brother, colleague) and characteristics which derive their meaning from comparison or interaction with other people (such as trustworthiness, shyness, sporting ability).F. Cooley and other researchers suggested a close connection between a person’s own understanding of their identity and other people’s understanding of it. Cooley believed that people build up their sense of identity form the reactions of others to them, and form the view they believe others have of them. He called the self-as-object the ‘looking-glass self’, since people come to see themselves as they are reflected in others. Mead (1934) went even further and saw the self and the social world as inextricably bound together: ‘Th e self is essentially a social structure, and it arises in social experience… it is impossible to conceive of a self arising outside of socialexperience.’G. Lewis and Brooks-Gunn argued that an important developmental milestone is reached when children become able to recognize themselves visually without the support of seeing contingent movement. This recognition occurs around their second birthday. In one experiment, Lewis and Brooks-Gunn (1979) dabbed some red powder on the noses of children who were playing in front of a mirror, and then observed how often they touched their noses. The psychologists reasoned that if the children knew what they usually looked like, they would be surprised by the unusual red mark and would start touching it. On the other hand, they found that children of 15 to 18 months are generally not able to recognize themselves unless other cues such as movement are present.H. Finally, perhaps the most graphic expressions of self-awareness in general can be seen in the displays of rage which are most common from 18 months to 3 years of age. In a longitudinal study of groups of three or four children, Bronson (1975) found that the intensity of the frustration and anger in their disagreements increased sharply between the ages of 1 and 2 years. Often, the children’s disagreements involved a struggle over a toy that none of them had played with before or after the tug-of-war: the children seemed to be disputing ownership rather than wanting to play with it. Although it may be less marked in other societies, the link between the sense of ‘self’ and of ‘ownership’ is a notable feature of childhood in Western societies.Questions 14—19Reading Passage 2 has eight paragraphs, A—H.Which paragraph contains the following information?Write the correct letter, A—H, in boxes 14-19 on your answer sheet.NB You may use any letter more than once.14 an account of the method used by researchers in a particular study15 the role of imitation in developing a sense of identity16 the age at which children can usually identify a static image of themselves17 a reason for the limitations of scientific research into ‘self-as-subject’18 reference to a possible link between culture and a particular form of behaviour19 examples of the wide range of features that contribute to the sense of ‘self-as-object’Questions 20—23Look at the following findings (Questions 20—23) and the list of researchers below.Match each finding with the correct researcher or researchers, A—E.Write the correct letter, A—E, in boxes 20—23 on your answer sheet.20 A sense of identity can never be formed without relationships with other people.21 A child’s awareness of self is related to a sense of mastery over things and people.22 At a certain age, children’s sense of identity leads t o aggressive behaviour.23 Observing their own reflection contributes to children’s self awareness.List of ResearchersA JamesB CooleyC Lewis and Brooks-GunnD MeadE BronsonQuestions 24—26Complete the summary below.Choose ONE WORD ONLY from the passage for each answer.Write your answers in boxes 24—26 on your answers sheet.How children acquire a sense of identityFirst, children come to realize that they can have an effect on the world around them,for example by handling objects, or causing the image to move when they face a 24 ______.

The conviction that historical relics provide infallible testimony about the past is rooted in the nineteenth and early twentieth centuries, when science was regarded as objective and value free. As one writer observes: ‘Although it is now evident that artefacts are as easily altered as chronicles, public faith in their veracity endures: a tangible relic seems ipso facto real’. Such conviction was, until recently, reflected in museum displays. Museums used to look — and some still do — much like storage rooms of objects packed together in showcases: good for scholars who wanted to study the subtle differences in design, but not for the ordinary visitor, to whom it all looked alike. Similarly, the information accompanying the objects often made little sense to the lay visitor. The content and format of explanations dated back to a time when the museum was the exclusive domain of the scientific researcher.B. Recently, however, attitudes towards history and the way it should be presented have altered. The key word in heritage display is now ‘experience’, the more exciting the better and, if possible, involving all the senses. Good examples of this approach in the UK are the Jorvik Centre in York; the National Museum of Photography, Film and Television in Bradford; and the Imperial War Museum in London. In the US the trend emerged much earlier: Williamsburg has been a prototype for many heritage developments in other parts of the world. No one can predict where the process will end. On so-called heritage sites the re-enactment of historical events is increasingly popular, and computers will soon provide virtual reality experiences, which will present visitors with a vivid image of the period of their choice, in which they themselves can act as if part of the historical environment. Such developments have been criticized as an intolerable vulgarization, but the success of many historical theme parks and similar locations suggests that the majority of the public does not share this opinion.C. In a related development, the sharp distinction between museum and heritage sites on the one hand, and theme parks on the other, is gradually evaporating. They already borrow ideas and concepts from one another. For example, museums have adopted story lines for exhibitions, sites have accepted ‘theming’ as a r elevant tool, and theme parks are moving towards more authenticity and research-based presentations. In zoos, animals are no longer kept in cages, but in great spaces, either in the open air or in enormous greenhouses, such as the jungle and desert environ ments in Burgers’ Zoo in Holland. This particular trend is regarded as one of the major developments in the presentation of natural history in the twentieth century.D. Theme parks are undergoing other changes, too, as they try to present more serious social and cultural issues, and move away from fantasy. This development is a response to market forces and, although museums and heritage sites have a special, rather distinct, role to fulfil, they are also operating in a very competitive environment, where visitors make choices on how and where to spend their free time. Heritage and museum experts do not have to invent stories and recreate historical environments to attract their visitors: their assets are already in place. However, exhibits must be both based on artefacts and facts as we know them, and attractively presented. Those who are professionally engaged in the art of interpreting history are thus in difficult position, as they must steer a narrow course between the demands of ‘evidence’ and ‘attractiveness’, especially given the increasing need in the heritage industry for income-generating activities.E. It could be claimed that in order to make everything in heritage more ‘real’, historical accuracy must be increasingly altered. For example, Pithecanthropus erectus is depicted in an Indonesian museum with Malay facial features, because this corresponds to public perceptions. Similarly, in the Museum of Natural History in Washington, Neanderthal man is shown making a dominant gesture to his wife. Such presentations tell us more about contemporary perceptions of the world than about our ancestors. There is one compensation, however, for the professionals who make these interpretations: if they did not provide the interpretation, visitors would do it for themselves, based on their own ideas, misconceptions and prejudices. And no matter how exciting the result, it would contain a lot more bias than the presentations provided by experts.F. Human bias is inevitable, but another source of bias in the representation of history has to do with the transitory nature of the materials themselves. The simple fact is that not everything from history survives the historical process. Castles, palaces and cathedrals have a longer lifespan than the dwellings of ordinary people. The same applies to the furnishing and other contents of the premises. In a town like Leyden in Holland, which in the seventeenth century was occupied by approximately the same number of inhabitants as today, people lived within the walled town, an area more than five times smaller than modern Leyden. In most of the houses several families lived together in circumstances beyond our imagination. Yet in museums, fine period rooms give only an image of the lifestyle of the upper class of that era. No wonder that people who stroll around exhibitions are filled with nostalgia; the evidence in museums indicates that life was so much better in past. This notion is induced by the bias in its representation in museums and heritage centres.Questions 31—36Choose the correct letter, A, B, C or D.Write the correct letter in boxes 31-36 on your answer sheet.31 Compared with today’s museums, those of the past.A did not present history in a detailed way.B were not primarily intended for the public.C were more clearly organised.D preserved items with greater care.32 According to the writer, current trends in the heritage industryA emphasise personal involvement.B have their origins in York and London.C rely on computer images.D reflect minority tastes.33 The writer says that museums, heritage sites and theme parksA often work in close partnership.B try to preserve separate identities.C have similar exhibits.D are less easy to distinguish than before.34 The writer says that in preparing exhibits for museums, expertsA should pursue a single objective.B have to do a certain amount of language translation.C should be free from commercial constraints.D have to balance conflicting priorities.35 In paragraph E, the writer suggests that some museum exhibitsA fail to match visitor expectations.B are based on the false assumptions of professionals.C reveal more about present beliefs than about the past.D allow visitors to make more use of their imagination.36 The passage ends by noting that our view of history is biased becauseA we fail to use our imagination.B only very durable objects remain from the past.C we tend to ignore things that displease us.D museum exhibits focus too much on the local area.Questions 37—40Do the following statements agree with the information given in Reading Passage 3?In boxes 37—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 this37 Consumers prefer theme parks which avoid serious issues.38 More people visit museums than theme parks.39 The boundaries of Leyden have changed little since the seventeenth century.40 Museums can give a false impression of how life used to be.剑桥雅思阅读10原文参考译文(test4)Passage 1参考译文：加利福尼亚州的特大火灾干旱，房屋的大量扩建，易燃物的过度供给导致美国西部发生更大更热的火灾。
