剑桥雅思阅读11原文(test3)READING PASSAGE 1You should spend about 20 minutes on Questions 1-13, which are based on Reading Passage 1 below.THE STORY OF SILKThe history of the world’s most luxurious fabric, from ancient China to the present daySilk is a fine, smooth material produced from the cocoons —soft protective shells —that are made by mulberry silkworms (insect larvae). Legend has it that it was Lei Tzu, wife of the Yellow Emperor, ruler of China in about 3000 BC, who discovered silkworms. One account of the story goes that as she was taking a walk in her husband’s gardens, she discovered that silkworms were responsible for the destruction of several mulberry trees. She collected a number of cocoons and sat down to have a rest. It just so happened that while she was sipping some tea, one of the cocoons that she had collected landed in the hot tea and started to unravel into a fine thread. Lei Tzu found that she could wind this thread around her fingers. Subsequently, she persuaded her husband to allow her to rear silkworms on a grove of mulberry trees. She also devised a special reel to draw the fibres from the cocoon into a single thread so that they would be strong enough to be woven into fabric. While it is unknown just how much of this is true, it is certainly known that silk cultivationhas existed in China for several millennia.Originally, silkworm farming was solely restricted to women, and it was they who were responsible for the growing, harvesting and weaving. Silk quickly grew into a symbol of status, and originally, only royalty were entitled to have clothes made of silk. The rules were gradually relaxed over the years until finally during the Qing Dynasty (1644-1911 AD), even peasants, the lowest caste, were also entitled to wear silk. Sometime during the Han Dynasty (206 BC-220 AD), silk was so prized that it was also used as a unit of currency. Government officials were paid their salary in silk, and farmers paid their taxes in grain and silk. Silk was also used as diplomatic gifts by the emperor. Fishing lines, bowstrings, musical instruments and paper were all made using silk. The earliest indication of silk paper being used was discovered in the tomb of a noble who is estimated to have died around 168 AD.Demand for this exotic fabric eventually created the lucrative trade route now known as the Silk Road, taking silk westward and bringing gold, silver and wool to the East. It was named the Silk Road after its most precious commodity, which was considered to be worth more than gold. The Silk Road stretched over 6,000 kilometres from Eastern China to the Mediterranean Sea, following the Great Wall of China, climbing the Pamir mountain range, crossing modern-day Afghanistan and going on to the Middle East, with a major trading market in Damascus. From there, the merchandise was shipped across the Mediterranean Sea. Few merchants travelled the entire route; goods were handled mostly by a series of middlemen.With the mulberry silkworm being native to China, the country was the world’s sole producer of silk for many hundreds of years. The secret of silk-making eventually reached the rest ofthe world via the Byzantine Empire, which ruled over the Mediterranean region of southern Europe, North Africa and the Middle East during the period 330-1453 AD. According to another legend, monks working for the Byzantine emperor Justinian smuggled silkworm eggs to Constantinople (Istanbul in modern-day Turkey) in 550 AD, concealed inside hollow bamboo walking canes. The Byzantines were as secretive as the Chinese, however, and for many centuries the weaving and trading of silk fabric was a strict imperial monopoly. Then in the seventh century, the Arabs conquered Persia, capturing their magnificent silks in the process. Silk production thus spread through Africa, Sicily and Spain as the Arabs swept through these lands. Andalusia in southern Spain was Europe’s main silk-producing centre in the tenth century. By the thirteenth century, however, Italy had become Europe’s leader in silk production and export. Venetian merchants traded extensively in silk and encouraged silk growers to settle in Italy. Even now, silk processed in the province of Como in northern Italy enjoys an esteemed reputation.The nineteenth century and industrialisation saw the downfall of the European silk industry. Cheaper Japanese silk, trade in which was greatly facilitated by the opening of the Suez Canal, was one of the many factors driving the trend. Then in the twentieth century, new manmade fibres, such as nylon, started to be used in what had traditionally been silk products, such as stockings and parachutes. The two world wars, which interrupted the supply of raw material from Japan, also stifled the European silk industry. After the Second World War, Japan’s silk production was restored, with improved production and quality of raw silk. Japan was to remain the world’s biggest producer of raw silk, and practically the only major exporter of raw silk, untilthe 1970s. However, in more recent decades, China has gradually recaptured its position as the world’s biggest producer and exporter of raw silk and silk yarn. Today, around 125,000 metric tons of silk are produced in the world, and almost two thirds of that production takes place in China.Questions 1-9Complete the notes below.Choose ONE WORD ONLY from the passage for each answer.Write your answers in boxes 1-9 on your answer sheet.THE STORY OF SILKEarly silk production in ChinaAround 3000 BC, according to legend:- silkworm cocoon fell into emperor’s wife’s 1 __________- emperor’s wife invented a 2 __________ to pull out silk fibresOnly 3 __________ were allowed to produce silkOnly 4 __________ were allowed to wear silkSilk used as a form of 5 __________- e.g. farmers’ taxes consisted partly of silkSilk used for many purposes- e.g. evidence found of 6 __________ made from silk around 168 ADSilk reaches rest of worldMerchants use Silk Road to take silk westward and bring back 7 __________ and precious metals550 AD: 8 __________ hide silkworm eggs in canes and take them to ConstantinopleSilk production spreads across Middle East and Europe20th century: 9 __________ and other manmade fibres cause decline in silk productionQuestions 10-13Do the following statements agree with the information in Reading Passage 1?In boxes 10-13 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 this10 Gold was the most valuable material transported along the Silk Road.11 Most tradesmen only went along certain sections of the Silk Road.12 The Byzantines spread the practice of silk production across the West.13 Silk yarn makes up the majority of silk currently exported from China.READING PASSAGE 2You should spend about 20 minutes on Questions 14-26, which are based on Reading Passage 2 below.Great MigrationsAnimal migration, however it is defined, is far more than just the movement of animals. It can loosely be described as travel that takes place at regular intervals ?— often in an annual cycle — that may involve many members of a species, and is rewarded only after a long journey. It suggests inherited instinct. The biologist Hugh Dingle has identified five characteristics that apply, in varying degrees and combinations, to all migrations. They are prolonged movements that carry animals outside familiar habitats; they tend to be linear, not zigzaggy; they involve special behaviours concerning preparation (such as overfeeding) and arrival; they demand special allocations of energy. And onemore: migrating animals maintain an intense attentiveness to the greater mission, which keeps them undistracted by temptations and undeterred by challenges that would turn other animals aside.An arctic tern, on its 20,000 km flight from the extreme south of South America to the Arctic circle, will take no notice of a nice smelly herring offered from a bird-watcher’s boat along the way. While local gulls will dive voraciously for such handouts, the tern flies on. Why? The arctic tern resists distraction because it is driven at that moment by an instinctive sense of something we humans find admirable: larger purpose. In other words, it is determined to reach its destination. The bird senses that it can eat, rest and mate later. Right now it is totally focused on the journey; its undivided intent is arrival.Reaching some gravelly coastline in the Arctic, upon which other arctic terns have converged, will serve its larger purpose as shaped by evolution: finding a place, a time, and a set of circumstances in which it can successfully hatch and rear offspring.But migration is a complex issue, and biologists define it differently, depending in part on what sorts of animals they study. Joe! Berger, of the University of Montana, who works on the American pronghorn and other large terrestrial mammals, prefers what he calls a simple, practical definition suited to his beasts: ‘movements from a seasonal home area away to another home area and back again’. Generally the reason for such seasonal back-and-forth movement is to seek resources that aren’t available within a single area year-round.But daily vertical movements by zooplankton in the ocean —upward by night to seek food, downward by day to escapepredators —can also be considered migration. So can the movement of aphids when, having depleted the young leaves on one food plant, their offspring then fly onward to a different host plant, with no one aphid ever returning to where it started.Dingle is an evolutionary biologist who studies insects. His definition is more intricate than Berger’s, citing those five features that distinguish migration from other forms of movement. They allow for the fact that, for example, aphids will become sensitive to blue light (from the sky) when it’s time for takeoff on their big journey, and sensitive to yellow light (reflected from tender young leaves) when it’s appropriate to land. Birds will fatten themselves with heavy feeding in advance of a long migrational flight. The value of his definition, Dingle argues, is that it focuses attention on what the phenomenon of wildebeest migration shares with the phenomenon of the aphids, and therefore helps guide researchers towards understanding how evolution has produced them all.Human behaviour, however, is having a detrimental impact on animal migration. The pronghorn, which resembles an antelope, though they are unrelated, is the fastest land mammal of the New World. One population, which spends the summer in the mountainous Grand Teton National Park of the western USA, follows a narrow route from its summer range in the mountains, across a river, and down onto the plains. Here they wait out the frozen months, feeding mainly on sagebrush blown clear of snow. These pronghorn are notable for the invariance of their migration route and the severity of its constriction at three bottlenecks. If they can’t pass through each of the three during their spring migration, they can’t reach their bounty of summer grazing; if they can’t pass through again in autumn, escaping south ontothose windblown plains, they are likely to die trying to overwinter in the deep snow. Pronghorn, dependent on distance vision and speed to keep safe from predators, traverse high, open shoulders of land, where they can see and run. At one of the bottlenecks, forested hills rise to form a V, leaving a corridor of open ground only about 150 metres wide, filled with private homes. Increasing development is leading toward a crisis for the pronghorn, threatening to choke off their passageway.Conservation scientists, along with some biologists and land managers within the USA’s National Park Service and other agencies, are now working to preserve migrational behaviours, not just species and habitats. A National Forest has recognised the path of the pronghorn, much of which passes across its land, as a protected migration corridor. But neither the Forest Service nor the Park Service can control what happens on private land at a bottleneck. And with certain other migrating species, the challenge is complicated further —by vastly greater distances traversed, more jurisdictions, more borders, more dangers along the way. We will require wisdom and resoluteness to ensure that migrating species can continue their journeying a while longer.Questions 14-18Do the following statements agree with the information given in Reading Passage 2?In boxes 14-18 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 this14 Local gulls and migrating arctic terns behave in the same way when offered food.15 Experts’ definitions of migration tend to vary accordingto their area of study.16 Very few experts agree that the movement of aphids can be considered migration.17 Aphids’ journeys are affected b y changes in the light that they perceive.18 Dingle’s aim is to distinguish between the migratory behaviours of different species.Questions 19-22Complete each sentence with the correct ending, A-G, below.Write the correct letter, A-G, in boxes 19-22 on your answer sheet.19 According to Dingle, migratory routes are likely to20 To prepare for migration, animals are likely to21 During migration, animals are unlikely to22 Arctic terns illustrate migrating animals’ ability toA be discouraged by difficulties.B travel on open land where they can look out for predators.C eat more than they need for immediate purposes.D be repeated daily.E ignore distractions.F be governed by the availability of water.G follow a straight line.Questions 23-26Complete the summary below.Choose ONE WORD ONLY from the passage for each answer.Write your answers in boxes 23-26 on your answer sheet.The migration of pronghornsPronghorns rely on their eyesight and 23 __________ to avoid predators.

So it is with mathematics as well. There are some discoveries in advanced mathematics that do not depend on specialized knowledge, not even on algebra, geometry, or trigonometry. Instead they may involve, at most, a little arithmetic, such as ‘the sum of two odd numbers is even’, and common sense. Each of the eight chapters in this book illustrates this phenomenon. Anyone can understand every step in the reasoning.The thinking in each chapter uses at most only elementary arithmetic, and sometimes not even that. Thus all readers will have the chance to participate in a mathematical experience, to appreciate the beauty of mathematics, and to become familiar with its logical, yet intuitive, style of thinking.B One of my purposes in writing this book is to give readers who haven’t had the opportunity to see and enjoy real mathematics the chance to appreciate the mathematical way of thinking. I want to reveal not only some of the fascinating discoveries, but, more importantly, the reasoning behind them.In that respect, this book differs from most books on mathematics written for the general public. Some present the lives of colorful mathematicians. Others describe important applications of mathematics. Yet others go into mathematical procedures, but assume that the reader is adept in using algebra.C I hope this book will help bridge that notorious gap that separates the two cultures: the humanities and the sciences, or should I say the right brain (intuitive) and the left brain (analytical, numerical). As the chapters will illustrate, mathematics is not restricted to the analytical and numerical; intuition plays a significant role. The alleged gap can be narrowed or completely overcome by anyone, in part because each of us is far from using the full capacity of either side of the brain. To illustrate our human potential, I cite a structural engineer who is an artist, an electrical engineer who is an opera singer, an opera singer who published mathematical research, and a mathematician who publishes short stories.D Other scientists have written books to explain their fields to non-scientists, but have necessarily had to omit the mathematics, although it provides the foundation of their theories. The reader must remain a tantalized spectator rather than an involved participant, since the appropriate language for describing the details in much of science is mathematics, whether the subject is expanding universe, subatomic particles, or chromosomes. Though the broad outline of a scientific theory can be sketched intuitively, when a part of the physical universe is finally understood, its description often looks like a page in a mathematics text.E Still, the non-mathematical reader can go far in understanding mathematical reasoning. This book presents thedetails that illustrate the mathematical style of thinking, which involves sustained, step-by-step analysis, experiments, and insights. You will turn these pages much more slowly than when reading a novel or a newspaper. It may help to have a pencil and paper ready to check claims and carry out experiments.F As I wrote, I kept in mind two types of readers: those who enjoyed mathematics until they were turned off by an unpleasant episode, usually around fifth grade, and mathematics aficionados, who will find much that is new throughout the book.This book also serves readers who simply want to sharpen their analytical skills. Many careers, such as law and medicine, require extended, precise analysis. Each chapter offers practice in following a sustained and closely argued line of thought. That mathematics can develop this skill is shown by these two testimonials:G A physician wrote, ‘The discipline of analytical thought processes [in mathematics] prepared me extremely well for medical school. In medicine one is faced with a problem which must be thoroughly analyzed before a solution can be found. The proces s is similar to doing mathematics.’A lawyer made the same point, ‘Although I had no background in law — not even one political science course — I did well at one of the best law schools. I attribute much of my success there to having learned, through the study of mathematics, and, in particular, theorems, how to analyze complicated principles. Lawyers who have studied mathematics can master the legal principles in a way that most others cannot.’I hope you will share my delight in watching as simple, even na?ve, questions lead to remarkable solutions and purely theoretical discoveries find unanticipated applications.Questions 27-34Reading Passage 3 has seven sections, A-G.Which section contains the following information?Write the correct letter, A-G, in boxes 27-34 on your answer sheet.NB You may use any letter more than once.27 a reference to books that assume a lack of mathematical knowledge28 the way in which this is not a typical book about mathematics29 personal examples of being helped by mathematics30 examples of people who each had abilities that seemed incompatible31 mention of different focuses of books about mathematics32 a contrast between reading this book and reading other kinds of publication33 a claim that the whole of the book is accessible to everybody34 a reference to different categories of intended readers of this bookQuestions 35-40Complete the sentences below.Choose ONE WORD ONLY from the passage for each answer.Write your answers in boxes 35-40 on your answer sheet.35 Some areas of both music and mathematics are suitable for someone who is a __________.36 It is sometimes possible to understand advanced mathematics using no more than a limited knowledge of __________.37 The writer intends to show that mathematics requires__________ thinking, as well as analytical skills.38 Some books written by __________ have had to leave out the mathematics that is central to their theories.39 The writer advises non-mathematical readers to perform __________ while reading the book.40 A lawyer found that studying __________ helped even more than other areas of mathematics in the study of law.剑桥雅思阅读11原文参考译文(test3)PASSAGE 1 参考译文：丝绸的故事世上最昂贵奢华织物的历史，从古代中国直到今天丝绸是种细软、光滑的布料，产自桑蚕(该昆虫的幼体形态)制作出的蚕茧——即其柔软的保护性外壳。

剑桥雅思阅读真题集1Reading Passage 1You should spend about 20 minutes on QUESTIONS 1-14 which are based on Reading Passage 1 belowAdults and children are frequently confronted with statements about the alarming rate of loss of tropical rainforests. For example, one graphic illustration to which children might readily relate is the estimate that rainforests are being destroyed at a rate equivalent to one thousand football fields every forty minutes — about the duration of a normal classroom period. In the face of the frequent and often vivid media coverage, it is likely that children will have formed ideas about rainforests — what and where they are, why they are important, what endangers them — independent of any formal tuition. It is also possible that some of these ideas will be mistaken.Many studies have shown that children harbour misconceptions about ‘pure’, curriculum science. These misconceptions do not remain isolated but become incorporated into a multifaceted, but organised, conceptual framework, making it and the component ideas, some of which are erroneous, more robust but also accessible to modification. These ideas may be developed by children absorbing ideas through the popular media. Sometimes this information may be erroneous. It seems schools may not be providing an opportunity for children to re-express their ideas and so have them tested and refined by teachers and their peers.Despite the extensive coverage in the popular media of the destruction of rainforests, little formal information is available about children’s ideas in this area. The aim of the present study is to start to provide such information, to help teachers design their educational strategies to build upon correct ideas and to displace misconceptions and to plan programmes in environmental studies in their schools.The study surveys children’s scientific knowledge and attitudes to rainforests. Secondary school children were asked to complete a questionnaire containing five open-form questions. The most frequent responses to the first question were descriptions which are self-evident from the term ‘rainforest’. Some children described them as damp, wet or hot. The second question concerned the geographical location of rainforests. The commonest responses were continents or countries: Africa (given by 43% of children), South America (30%), Brazil (25%). Some children also gave more general locations, such as being near the Equator.Responses to question three concerned the importance of rainforests. The dominant idea, raised by 64% of the pupils, was that rainforests provide animals with habitats. Fewer students responded that rainforests provide plant habitats, and even fewer mentioned the indigenous populations of rainforests. More girls (70%) than boys (60%) raised the idea of rainforest as animal habitats.Similarly, but at a lower level, more girls (13%) than boys (5%) said that rainforests provided human habitats. These observations are generally consistent with our previous studies of pupils’ views about the use and conservation of rainforests, in which girls were shown to be more sympathetic to animals and expressed views which seem to place an intrinsic value on non-human animal life.The fourth question concerned the causes of the destruction of rainforests. Perhaps encouragingly,more than half of the pupils (59%) identified that it is human activities which are destroying rainforests, some personalising the responsibility by the use of terms such as ‘we are’. About 18% of the pupils referred specifically to logging activity.One misconception, expressed by some 10% of the pupils, was that acid rain is responsible for rainforest destruction; a similar proportion said that pollution is destroying rainforests. Here, children are confusing rainforest destruction with damage to the forests of Western Europe by these factors. While two fifths of the students provided the information that the rainforests provide oxygen, in some cases this response also embraced the misconception that rainforest destruction would reduce atmospheric oxygen, making the atmosphere incompatible with human life on Earth.In answer to the final question about the importance of rainforest conservation, the majority of children simply said that we need rainforests to survive. Only a few of the pupils (6%) mentioned that rainforest destruction may contribute to global warming. This is surprising considering the high level of media coverage on this issue. Some children expressed the idea that the conservation of rainforests is not important.The results of this study suggest that certain ideas predominate in the thinking of children about rainforests. Pupils’ responses indicate some misconceptions in basic scientific knowledge of rainforests’ ecosystems such as their ideas about rainforests as habitats for animals, plants and humans and the relationship between climatic change and destruction of rainforests.Pupils did not volunteer ideas that suggested that they appreciated the complexity of causes of rainforest destruction. In other words, they gave no indication of an appreciation of either the range of ways in which rainforests are important or the complex social, economic and political factors which drive the activities which are destroying the rainforests. One encouragement is that the results of similar studies about other environmental issues suggest that older children seem to acquire the ability to appreciate, value and evaluate conflicting views. Environmental education offers an arena in which these skills can be developed, which is essential for these children as future decision-makers.Questions 1-8Do the following statements agree with the information given in Reading Passage 1?In boxes 1-8 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 The plight of the rainforests has largely been ignored by the media.2 Children only accept opinions on rainforests that they encounter in their classrooms.3 It has been suggested that children hold mistaken views about the ‘pure’ science that they study at school.4 The fact that children’s ideas about science form part of a larger framework of ideas means thatit is easier to change them.5 The study involved asking children a number of yes/no questions such as ‘Are there any rainforests in Africa?’6 Girls are more likely than boys to hold mistaken views about the rainforests’ destruction.7 The study reported here follows on from a series of studies that have looked at children’s understanding of rainforests.8 A second study has been planned to investigate primary school children’s ideas about rainforests.Questions 9-13The box below gives a list of responses A-P to the questionnaire discussed in Reading Passage 1.Answer the following questions by choosing the correct responses A-P.Write your answers in boxes 9-13 on your answer sheet.9 What was the children’s most frequent response when asked where the rainforests were?10 What was the most common response to the question about the importance of the rainforests?11 What did most children give as the reason for the loss of the rainforests?12 Why did most children think it important for the rainforests to be protected?13 Which of the responses is cited as unexpectedly uncommon, given the amount of time spent on the issue by the newspapers and television?Question 14Choose the correct letter, A, B, C, D or E.Write your answer in box 14 on your answer sheet.Which of the following is the most suitable title for Reading Passage 1?A The development of a programme in environmental studies within a science curriculumB Children’s ideas about the rainforests and the implications for course designC The extent to which children have been misled by the media concerning the rainforestsD How to collect, collate and describe the ideas of secondary school children.E The importance of the rainforests and the reasons for their destructionREADING PASSAGE 2You should spend about 20 minutes on Questions 15-26 which are based on Reading Passage 2 below.What Do Whales Feel?An examination of the functioning of the senses in cetaceans, the group of mammals comprising whales, dolphins and porpoisesSome of the senses that we and other terrestrial mammals take for granted are either reduced or absent in cetaceans or fail to function well in water. For example, it appears from their brain structure that toothed species are unable to smell. Baleen species, on the other hand, appear to have some related brain structures but it is not known whether these are functional. It has been speculated that, as the blowholes evolved and migrated to the top of the head, the neural pathways serving sense of smell may have been nearly all sacrificed. Similarly, although at least some cetaceans have taste buds, the nerves serving these have degenerated or are rudimentary.The sense of touch has sometimes been described as weak too, but this view is probably mistaken. Trainers of captive dolphins and small whales often remark on their animals’ responsiveness to being touched or rubbed, and both captive and free-ranging cetacean individuals of all species (particularly adults and calves, or members of the same subgroup) appear to make frequent contact. This contact may help to maintain order within a group, and stroking or touching are part of the courtship ritual in most species. The area around the blowhole is also particularly sensitive and captive animals often object strongly to being touched there.The sense of vision is developed to different degree in different species. Baleen species studied at close quarters underwater — specifically a grey whale calf in captivity for a year, and free-ranging right whale and humpback whales studied and filmed off Argentina and Hawaii — have obviously tracked objects with vision underwater, and they can apparently see moderately well both in water and in air. However, the position of the eyes so restricts the field of vision in baleen whales that they probably do not have stereoscopic vision.On the other hand, the position of the eyes in most dolphins and porpoises suggests that they have stereoscopic vision forward and downward. Eye position in freshwater dolphins, which often swim on their side or upside down while feeding, suggests that what vision they have is stereoscopic forward and upward. By comparison, the bottlenose dolphin has extremely keenvision in water. Judging from the way it watches and tracks airborne flying fish, it can apparently see fairly well through the air-water interface as well. And although preliminary experimental evidence suggests that their in-air vision is poor, the accuracy with which dolphins leap high to take small fish out of a trainer’s hand provides anecdotal evidence to the contrary.Such variation can no doubt be explained with reference to the habitats in which individual species have developed. For example, vision is obviously more useful to species inhabiting clear open waters than to those living in turbid rivers and flooded plains. The South American boutu and Chinese Beiji, for instance, appear to have very limited vision, and the Indian susus are blind, their eyes reduced to slits that probably allow them to sense only the direction and intensity of light.Although the senses of taste and smell appear to have deteriorated, and vision in water appears to be uncertain, such weaknesses are more than compensated for by cetaceans’ well-developed acoustic sense. Most species are highly vocal, although they vary in the range of sounds they produce, and many forage for food using echolocation1. Large baleen whales primarily use the lower frequencies and are often limited in their repertoire. Notable exceptions are the nearly song-like choruses of bowhead whales in summer and the complex, haunting utterances of the humpback whales. Toothed species in general employ more of the frequency spectrum, and produce a wider variety of sounds, than baleen species (though the sperm whale apparently produces a monotonous series of high-energy clicks and little else). Some of the more complicated sounds are clearly communicative, although what role they may play in the social life and ‘culture’ of cetaceans has been more the subject of wild speculation than of solid science.1. echolocation: the perception of objects by means of sound wave echoes.Questions 15-21Complete the table below.Choose NO MORE THAN THREE WORDS from Reading Passage 2 for each answer.Write your answers in boxes 15-21 on your answer sheet.Questions 22-26Answer the questions below using NO MORE THAN THREE WORDS from the passage for each answer.Write your answers in boxes 22-26 on your answer sheet.22 Which of the senses is described here as being involved in mating?23 What species swims upside down while eating?24 What can bottlenose dolphins follow from under the water?25 Which type of habitat is related to good visual ability?26 Which of the senses is best developed in cetaceans?READING PASSAGE 3You should spend about 20 minutes on Questions 27-40 which are based on Reading Passage 3 below.Visual Symbols and the BlindFrom a number of recent studies, it has become clear that blind people can appreciate the use of outlines and perspectives to describe the arrangement of objects and other surfaces in space. But pictures are more than literal representations. This fact was drawn to my attention dramatically when a blind woman in one of my investigations decided on her own initiative to draw a wheel as it was spinning. To show this motion, she traced a curve inside the circle (Fig. 1). I was taken aback. Lines of motion, such as the one she used, are a very recent invention in the history of illustration. Indeed, as art scholar David Kunzle notes, Wilhelm Busch, a trend-setting nineteenth-century cartoonist, used virtually no motion lines in his popular figures until about 1877.When I asked several other blind study subjects to draw a spinning wheel, one particularly clever rendition appeared repeatedly: several subjects showed the wheel’s spokes as curved lines. When asked about these curves, they all described them as metaphorical ways of suggesting motion. Majority rule would argue that this device somehow indicated motion very well. But was it a better indicator than, say, broken or wavy lines — or any other kind of line, for that matter? The answer was not clear. So I decided to test whether various lines of motion were apt ways of showing movement or if they were merely idiosyncratic marks. Moreover, I wanted to discover whether there were differences in how the blind and the sighted interpreted lines of motion.To search out these answers, I created raised-line drawings of five different wheels, depicting spokes with lines that curved, bent, waved, dashed and extended beyond the perimeter of the wheel. I then asked eighteen blind volunteers to feel the wheels and assign one of the following motions to each wheel: wobbling, spinning fast, spinning steadily, jerking or braking. My control group consisted of eighteen sighted undergraduates from the University of Toronto.All but one of the blind subjects assigned distinctive motions to each wheel. Most guessed that the curved spokes indicated that the wheel was spinning steadily; the wavy spokes, they thought, suggested that the wheel was wobbling; and the bent spokes were taken as a sign that the wheel was jerking. Subjects assumed that spokes extending beyond the wheel’s perimeter signified that the wheel had its brakes on and that dashed spokes indicated the wheel was spinning quickly.In addition, the favoured description for the sighted was the favoured description for the blind in every instance. What is more, the consensus among the sighted was barely higher than that among the blind. Because motion devices are unfamiliar to the blind, the task I gave them involved some problem solving. Evidently, however, the blind not only figured out meanings for each line of motion, but as a group they generally came up with the same meaning at least as frequently as did sighted subjects.We have found that the blind understand other kinds of visual metaphors as well. One blind woman drew a picture of a child inside a heart – choosing that symbol, she said, to show that love surrounded the child. With Chang Hong Liu, a doctoral student from China, I have begun exploring how well blind people understand the symbolism behind shapes such as hearts that do not directly represent their meaning.We gave a list of twenty pairs of words to sighted subjects and asked them to pick from each pair the term that best related to a circle and the term that best related to a square. For example, we asked: What goes with soft? A circle or a square? Which shape goes with hard?All our subjects deemed the circle soft and the square hard. A full 94% ascribed happy to the circle, instead of sad. But other pairs revealed less agreement: 79%matched fast to slow and weak to strong, respectively. And only 51% linked deep to circle and shallow to square. (See Fig. 2) When we tested four totally blind volunteers using the same list, we found that their choices closely resembled those made by the sighted subjects. One man, who had been blind since birth, scored extremely well. He made only one match differing from the consensus, assigning ‘far’ to square and ‘near’ to circle. In fact, only a small majority of sighted subjects – 53% – had paired far and near to the opposite partners. Thus, we concluded that the blind interpret abstract shapes as sighted people do.Choose the correct letter, A, B, C or D.Write your answers in boxes 27-29 on your answer sheet.27 In the first paragraph the writer makes the point that blind people.A may be interested in studying art.B can draw outlines of different objects and surfaces.C can recognise conventions such as perspective.D can draw accurately.28 The writer was surprised because the blind womanA drew a circle on her own initiative.B did not understand what a wheel looked like.C included a symbol representing movement.D was the first person to use lines of motion.29 From the experiment described in Part 1, the writer found that the blind subjectsA had good understanding of symbols representing movement.B could control the movement of wheels very accurately.C worked together well as a group in solving problems.D got better results than the sighted undergraduates.Questions 30-32Look at the following diagrams (Questions 30-32), and the list of types of movement below. Match each diagram to the type of movement A-E generally assigned to it the experiment. Choose the correct letter A-E and write them in boxes 30-32 on your answer sheet.Complete the summary below using words from the box.Write your answers in boxes 33-39 on your answer sheet.NB You may use any word more than once.In the experiment described in Part 2, a set of word 33…… was used to investigate whether blind and sighted people perceived the symbolism in abstract 34…… in the same way.

剑桥雅思真题7-阅读Test 3（附答案）Reading Passage 1You should spend about 20 minutes on QUESTIONS 1-13 which are based on Reading Passage 1 below.Ant IntelligenceWhen we think of intelligent members of the animal kingdom, the creatures that spring immediately to mind are apes and monkeys. But in fact the social lives of some members of the insect kingdom are sufficiently complex to suggest more than a hint of intelligence. Among these, the world of the ant has come in for considerable scrutiny lately, and the idea that ants demonstrate sparks of cognition has certainly not been rejected by those involved in these investigations.Ants store food, repel attackers and use chemical signals to contact one another in case of attack. Such chemical communication can be compared to the human use of visual and auditory channels (as in religious chants, advertising images and jingle s, political slogans and martial music) to arouse and propagate moods and attitudes. The biologist Lewis Thomas wrote, Ants are so much like human beings as to be an embarrassment. They farm fungi, raise aphids* as livestock, launch armies to war, use chemical sprays to alarm and confuse enemies, capture slaves, engage in child lab our, exchange information ceaselessly. They do everything but watch television.'However, in ants there is no cultural transmission -everything must be encoded in the genes -whereas in humans the opposite is true. Only basic instincts are carried in the genes of a newborn baby, other skills being learned from others in the community as the child grows up. It may seem that this cultural continuity gives us a huge advantage over ants. They have never mastered fire nor progressed. Their fungus farming and aphid herding crafts are sophisticated when compared to the agricultural skills of humans five thousand years ago but been totally overtaken by modern human agribusiness.Or have they? The farming methods of ants are at least sustainable. They do not ruin environments or use enormous amounts of energy. Moreover, recent evidence suggests that the crop farming of ants may be more sophisticated and adaptable than was thought.Ants were farmers fifty million years before humans were. Ants can't digest the cellulose in leaves - but some fungi can. They therefore cultivate these fungi in their nests, bringing them leaves to feed on, and then use them as a source of food. Farmer ants secrete antibiotics to control other fungi that might ac t as 'weeds', and spread waste to fertilize the crop.It was once thought that the fungus that ants cultivate was a single type that they had propagated, essentially unchanged from the distant past. Not so. Ulrich Mueller of Maryland and his colleagues genetically screened 8 62 different types of fungi taken from ants' nests. These turned out to be highly diverse: it seems that ants are continually domesticating new species. Even more impressively, DNA analysis of the fungi suggests that the ants improve or modify the fungi by regularly swapping and sharing strains with neighbouring ant colonies.Whereas prehistoric man had no exposure to urban lifestyles - the forcing house of intelligence -the evidence suggests that ants have lived in urban settings for close on a hundred million years, developing and maintaining underground cities of specialised chambers and tunnels.When we survey Mexico City, Tokyo, Los Angeles, we are amazed at what has been accomplishedby humans. Yet Hoelldobler and Wilson's magnificent work for ant lovers, The Ants, describes a supercolony of the ant Formica yessensis on the Ishikari Coast of Hokkaido. This 'megalopolis' was reported to be compose d of 360 million workers and a million queens living in 4, 500 interconnected nests a cross a territory of 2.7 square kilometres.Such enduring and intricately meshed levels of technical achievement outstrip by far anything achieved by our distant ancestors. We hail as masterpieces the cave paintings in southern France and elsewhere, dating back some 20,000 years. Ant societies existed in something like their present form more than seventy million years ago. Beside this, prehistoric ma n looks technologically primitive. Is this then some kind of intelligence, albeit of a different kind? Research conducted at Oxford, Sussex and Zurich Universities has shown that when desert ants return from a foraging trip, they navigate by integrating bearings and distances, which they continuously update in their heads. They combine the evidence of visual landmarks with a mental library of local directions, all within a framework which is consulted and updated. So ants can learn too.And in a twelve-year programmed of work, Ryabko and Reznikova have found evidence that ants can transmit very complex messages. Scouts who had located food in a maze returned to mobilise their foraging teams. They engaged in contact sessions, at the end of which the scout was removed in order to observe what her team might do. Often the foragers proceeded to the exact spot in the maze where the food had been. Elaborate precautions were taken to prevent the foraging team using odor clues. Discussion now centres on whether the route through the maze is communicated as a 'left-right' sequence of turns or as a 'compass bearing and distance ' message.During the course of this exhaustive study, Reznikova has grown so attached to her laboratory ants that she feels she knows them as individuals - even without the paint spots used to mark them. It's no surprise that Edward Wilson, in his essay, 'In the company of ants', advises readers who ask what to do with the ants in their kitchen to: 'Watch where you step. Be careful of little lives.' Question 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 this in the passage1. Ants use the same channels of communication as humans do.2. City life is one factor that encourages the development of intelligence.3. Ants can build large cities more quickly than humans do.4. Some ants can find their way by making calculations based on distance and position.5. In one experiment, foraging teams were able to use their sense of smell to find food.6. The essay, ‘In the company of ants’, explores ant communication.Question 7-13Complete the summary using the list of words, A-O, below.Write the correct letter, A-O, in boxes 7-13 on your answer sheet.Ants have sophisticated methods of farming, including herding livestock and growing crops, which are in many ways similar to those used in human agriculture.

A number of techniques developed since the 1950s, however, have placed the study of these subjects on a sounder and more objective footing. The best information on early population movements is now being obtained from the 'archaeology of the living body', the clues to be found in genetic material.B Recent work on the problem of when people first entered the Americas is an example of the value of these new techniques. North-east Asia and Siberia have long been accepted as the launching ground for the first human colonizers of the New World. But was there one major wave of migration across the Bering Strait into the Americas, or several? And when did this event, or events, take place？In recent years, new clues have come from research into genetics, including the distribution of genetic markers in modern Native Americans.C An important project, led by the biological anthropologist Robert Williams, focused on the variants (called Gm allotypes) of one particular protein -immunoglobin G-found in the fluid portion of human blood. All proteins 'drift', or produce variants, over the generations, and members of an interbreeding human population will share a set of such variants. Thus, by comparing the Gm allotypes of two different populations (e.g. two Indian tribes), one can establish their genetic 'distance', which itself can be calibrated to give an indication of the length of time since these populations last interbred.D Williams and his colleagues sampled the blood of over 5,000 American Indians in western North America during a twenty- year period. They found that their Gm allotypes could be divided into two groups, one of which also corresponded to the genetic typing of Central and South American Indians. Other tests showed that the Inuit (or Eskimo) and Aleut formed a third group. From this evidence it was deduced that there had been three major waves of migration across the Bering Strait. The first, Paleo-lndian, wave more than 15,000 years ago was ancestral to all Central and South American Indians. The second wave, about 14,000-12,000 years ago, brought Na-Dene hunters, ancestors of the Navajo and Apache (who only migrated south from Canada about 600 or 700 years ago). The third wave, perhaps 10,000 or 9,000 years ago, saw the migration from North-east Asia of groups ancestral to the modern Eskimo and Aleut.E How far does other research support these conclusions ？Geneticist Douglas Wallace has studied mitochondrial DNA in blood samples from three widely separated Native American groups: Pima- Papago Indians in Arizona, Maya Indians on the Y ucatan peninsula, Mexico, and Ticuna Indians in the Upper Amazon region of Brazil. As would have been predicted by Robert Williams's work, all three groups appear to be descended from the same ancestral (Paleo-lndian) population.F There are two other kinds of research that have thrown some light on the origins of the Native American population; they involve the study of teeth and of languages. The biological anthropologist Christy Turner is an expert in the analysis of changing physical characteristics in human teeth. He argues that tooth crowns and roots have a high genetic component, minimally affected by environmental and other factors. Studies carried out by Turner of many thousands of New and Old World specimens, both ancient and modern, suggest that the majority of prehistoric Americans are linked to Northern Asian populations by crown and root traits such as incisor shoveling (a scooping out on one or both surfaces of the tooth), single-rooted upper first premolars and triple-rooted lower first molars.According to Turner, this ties in with the idea of a single Paleo-lndian migration out of North Asia, which he sets at before 14,000 years ago by calibrating rates of dental micro-evolution. Tooth analyses also suggest that there were two later migrations of Na-Denes and Eskimo- Aleut.G The linguist Joseph Greenberg has, since the 1950s, argued that all Native American languages belong to a single 'Amerind' family, except for Na-Dene and Eskimo-Aleut - a view that gives credence to the idea of three main migrations. Greenberg is in a minority among fellow linguists, most of whom favour the notion of a great many waves of migration to account for the more than 1,000 languages spoken at one time by American Indians. But there is no doubt that the new genetic and dental evidence provides strong backing for Greenberg's view. Dates given for the migrations should nevertheless be treated with caution, except where supported by hard archaeological evidence.Question 14-19Reading Passage 2 has seven paragraphs, A-GChoose the correct heading for paragraphs A-F from the list of headings below.Write the correct number, i-x, into boxes 14-19 on your answer sheet.14Section A15Section A16Section A17Section A18Section A19Section AThe discussion of Williams's research indicates the periods at which early people are thought to have migrated along certain routes.

The decline of Europe's forests over the last decade and a half has led to an increasing awareness and understanding of the serious imbalances which threaten them.European countries are becoming increasingly concerned by major threats to European forests, threats which know no frontiers other than those of geography or climate: air pollution, soil deterioration, the increasing number of forest fires and sometimes even the mismanagement of our woodland and forest heritage. There has been a growing awareness of the need for countries to get together to co-ordinate their policies. In December 1990, Strasbourg hosted the first Ministerial Conference on the protection of Europe's forests. The conference brought together 31 countries from both Western and Eastern Europe. The topics discussed included the co-ordinated study of the destruction of forests, as well as how to combat forest fires and the extension of European research programs on the forest ecosystem. The preparatory work for the conference had been undertaken at two meetings of experts. Their initial task was to decide which of the many forest problems of concern to Europe involved the largest number of countries and might be the subject of joint action. Those confined to particular geographical areas, such as countries bordering the Mediterranean or the Nordic countriestherefore had to be discarded. However, this does not mean that in future they will be ignored.As a whole, European countries see forests as performing a triple function: biological, economic and recreational. The first is to act as a 'green lung' for our planet; by means of photosynthesis, forests produce oxygen through the transformation of solar energy, thus fulfilling what for humans is the essential role of an immense, non-polluting power plant. At the same time, forests provide raw materials for human activities through their constantly renewed production of wood. Finally, they offer those condemned to spend five days a week in an urban environment an unrivalled area of freedom to unwind and take part in a range of leisure activities, such as hunting, riding and hiking. The economic importance of forests has been understood since the dawn of man - wood was the first fuel. The other aspects have been recognised only for a few centuries but they are becoming more and more important. Hence, there is a real concern throughout Europe about the damage to the forest environment which threatens these three basic roles.The myth of the 'natural' forest has survived, yet there are effectively no remaining 'primary' forests in Europe. All European forests are artificial, having been adapted and exploited by man for thousands of years. This means that a forest policy is vital, that it must transcend national frontiers and generations of people, and that it must allow for the inevitable changes that take place in the forests, in needs, and hence in policy. The Strasbourg conference was one of the first events on such a scale to reach this conclusion. A general declaration was made that 'a central place in any ecologically coherent forest policy must be given to continuity over time and to the possible effects of unforeseen events, to ensure that the full potential of these forests is maintained'.That general declaration was accompanied by six detailed resolutions to assist national policy-making. The first proposes the extension and systematisation of surveillance sites to monitor forest decline. Forest decline is still poorly understood but leads to the loss of a high proportion of a tree's needles or leaves. The entire continent and the majority of species are now affected: between 30%and 50% of the tree population. The condition appears to result from the cumulative effect of a number of factors, with atmospheric pollutants the principal culprits. Compounds of nitrogen and sulphur dioxide should be particularly closely watched. However, their effects are probably accentuated by climatic factors, such as drought and hard winters, or soil imbalances such as soil acidification, which damages the roots. The second resolution concentrates on the need to preserve the genetic diversity of European forests. The aim is to reverse the decline in the number of tree species or at least to preserve the 'genetic material' of all of them. Although forest fires do not affect all of Europe to the same extent, the amount of damage caused the experts to propose as the third resolution that the Strasbourg conference consider the establishment of a European databank on the subject. All information used in the development of national preventative policies would become generally available. The subject of the fourth resolution discussed by the ministers was mountain forests. In Europe, it is undoubtedly the mountain ecosystem which has changed most rapidly and is most at risk. A thinly scattered permanent population and development of leisure activities, particularly skiing, have resulted in significant long-term changes to the local ecosystems. Proposed developments include a preferential research program on mountain forests. The fifth resolution relaunched the European research network on the physiology of trees, called Eurosilva. Eurosilva should support joint European research on tree diseases and their physiological and biochemical aspects. Each country concerned could increase the number of scholarships and other financial support for doctoraltheses and research projects in this area. Finally, the conference established the framework for a European research network on forest ecosystems. This would also involve harmonising activities in individual countries as well as identifying a number of priority research topics relating to the protection of forests. The Strasbourg conference's main concern was to provide for the future. This was the initial motivation, one now shared by all 31 participants representing 31 European countries. Their final text commits them to on-going discussion between government representatives with responsibility for forests.Question 27-33Do the following statements agree with the information given in Reading Passage 3?In boxes 27-33 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 this in the passage27.

剑桥雅思真题5-阅读Test1（附答案）Reading Passage 1You should spend about 20 minutes on QUESTIONS 1-13 which are based on Reading Passage 1 below.Johnson’s DictionaryFor the century 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 the various 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 Gough 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 every subject, 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 theprinciple 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 Ⅲto 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.

Stanley Milgram of Yale University tested 40 subjects from all walks of life for 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, Milgram 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 experimental 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 writhings 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, Milgram calmly 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 1000 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 teacher-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 setting.'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 authority figure. 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. Question 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 continueQuestion 20-22Choose the correct letter, A, B, C or D.Write your answers in boxes 20-22 on your answer sheet.20.

Several of the subjects were psychology students at Yale University.24. Some people may believe that the teacher-subjects’ behaviour could be explained 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 2below.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 in1972 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^ 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°C 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 emissionsradically 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 worlds single, most pressing health problem: providing universal access to clean drinking water and sanitation. Such measures would avoid 2 million deaths every year, and prevent 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.Question 27-32Do the following statements agree with the claims of the writer in Reading Passage 3?In boxes 27-32 on your answer sheet, writeTRUE if the statement agrees with the writer's claimsFALSE if the statement contradicts the writer's claimsNOT GIVEN if it is impossible to say what the writer thinks about this27. Environmentalists take a pessimistic view of the world for a number of reasons.28. Data on the Earth's natural resources has only been collected since 1972.29.

Some pollution problems have been correctly linked to industrialisation.32. It would be best to attempt to slow down economic growth.Question 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.

Some support more important issues than others.36. The writer suggests that newspapers print items that are intended toA. educate readers.B. meet their readers' expectations.C. encourage feedback from readers.D. mislead readers.37.

参考文章：Human Remain in Green SaharaAOn October 13,2,000, a small team of paleontologists led by Paul Sereno of the University of Chicago clambered out of three battered Land Rovers, filled their water bottles, and scattered on foot across the toffee-colored sands of the Tenere desert in northern Niger. The Tenere，on the southern flank of the Sahara, easily ranks among the most desolate landscapes on Earth. The Tuareg，turbaned nomads who for centurieshave ruled this barren realm, refer to it as a “desert within a desert”a California-size ocean of sand and rock, where a single massive dune might stretch a hundred miles, and the combination of 120-degreeheat and inexorable winds can wick the water from a human body in less than a day. The harsh conditions, combined with intermittent conflict between the Tuareg and the Niger government, have kept the region largely unexplored.BMike Hettwer, a photographer accompanying the team, headed off by himself toward a trio of small dunes. He crested the first slope and stared in amazement. The dunes were spilling over with bones. He took a few shots with his digital camera and hurried back to the Land Rovers. ‘I found some bones:’Hettwer said, when the team had regrouped. “But they’re not dinosaurs. They’re human.”CIn the spring of 2005 Sereno contacted Elena Garcea, an archaeologist at the University of Cassino, in Italy, inviting her to accompany him on a return to the site. Garcea had spent three decades working digs along the Nile in Sudan and in the mountains of the Libyan Desert, and was well acquainted with the ancient peoples of the Sahara. But she had never heard of Paul Sereno. His claim to have found so many skeletons in one place seemed far fetched, given that no other Neolithic cemeterycontained more than a dozen or so. Some archaeologists would later be skeptical; one sniped that he was just a ‘moonlighting paleontologist.’But Garcea was too intrigued to dismiss him as an interloper. She agreed to join him.DGarcea explained that the Kiffian were a fishing-based culture and lived during the earliest wet period, between 8,000 and 10,000 years ago. She held a Kiffian sherd next to a Tenerian one. “What is so amazing is that the people who made these two pots lived more than a thousand years apart.EOver the next three weeks, Sereno and Garcea-- along with five American excavators, five Tuareg guides, and five soldiers from Niger’s army, sent to protect the camp from bandits-- made a detailed map of the site, which they dubbed Gobero, after the Tuareg name for the area. They exhumed eight burials and collected scores of artifacts from both cultures. In a dry lake bed adjacent to the dunes, they found dozens of fishhooks and harpoons carved from animal bone. Apparently the Kiffian fishermen weren’t just going after small fry: Scattered near the dunes were the remains of Nile perch, a beast of a fish that can weigh nearly 300 pounds, as well as crocodile and hippo bones.FSereno flew home with the most important skeletons and artifacts and immediately began planning for the next field season. In the meantime, he carefully removed one tooth from each of four skulls and sent them to a lab for radiocarbon dating. The results pegged the age of the tightly bundled burial sat roughly 9,000 years old, the heart of the Kiffian era. The smaller ‘sleeping’skeletons turned out to be about 6,000 years old, well within the Tenerian period. At least now the scientists knew who was who.G In the fall of 2006 they returned to Gobero, accompanied by a larger dig crew and six additional scientists. Garcea hoped to excavate some80 burials, and the team began digging. As the skeletons began to emerge from the dunes, each presented a fresh riddle, especially the Tenerian. A male skeleton had been buried with a finger in his mouth.HEven at the site, Arizona State University bioarchaeologist Chris Stojanowski could begin to piece together some clues. Judging by the bones, the Kiffian appeared t o be a peaceful, hardworking people. “The lack of head and forearm injuries suggests they weren’t doing much fighting,” he told me. “And these guys were strong.” He pointed to a long，narrow ridge running along a femur. “That’s the muscle attachment，” he said. “This individual had huge leg muscles, which means he was eating a lot of protein and had a strenuous lifestyle-- bothconsistent with a fishing way of life.” For contrast, he showed me the femur of a Tenerian male. The ridge was barely perceptible. “T his guy had a much less strenuous lifestyle,” he said, “which you might expect of a herder.”IStojanowski’s assessment that the Tenerian were herders fits the prevailing view among scholars of life in the Sahara 6,000 years ago, when drier conditions favored herding over hunting. But if the Tenerian were herders, Sereno pointed out, where were the herds? Among the hundreds of animal bones that had turned up at the site, none belonged to goats or sheep, and only three came from a cow species. “It’s not unusual for a herding culture not to slaughter their cattle, particularly in a cemetery，M Garcea responded, noting that even modem pastoralists, such as Niger’s Wodaabe, are loath to butcher even one animal in their herd. Perhaps, Sereno reasoned, the Tenerian at Gobero were a transitional group that had not fully adopted herding and still relied heavily on hunting and fishing.JBack in Arizona, Stojanowski continues to analyze the Gobero bones for clues to the Green Saharans’health and diet. Other scientists are trying to derive DNA from the teeth, which could reveal the genetic origins of the Kiffian and Tenerian —and possibly link them todescendants living today. Sereno and Garcea estimate a hundred burials remain to be excavated. But as the harsh Tenere winds continue to erode the dunes, time is running out. “Every archaeological site has a life cycle，” Garcea said. “It begins when people begin to use the place, followed by disuse, then nature takes over, and finally it is gone. Gobero is at the end of its life.”。

剑桥雅思真题4-阅读test3（附答案）Reading Passage 1You should spend about 20 minutes on QUESTIONS 1-13 which are based on Reading Passage 1 below.Although small-scale business training and credit programs have become more common throughout the world, relatively little attention has been paid to the need to direct such opportunities to young people. Even less attention has been paid to children living on the street or in difficult circumstances.Over the past nine years, Street Kids International (S.K.I.) has been working with partner organisations in Africa, Latin America and India to support the economic lives of street children. The purpose of this paper is to share some of the lessons S.K.I. and our partners have learned.BackgroundTypically, children do not end up on the streets due to a single cause, but to a combination of factors: a dearth of adequately funded schools, the demand for income at home, family breakdown and violence. The street may be attractive to children as a place to find adventurous play and money. However, it is also a place where some children are exposed, with little or no protection, to exploitative employment, urban crime, and abuse.Children who work on the streets are generally involved in unskilled, labour-intensive tasks which require long hours, such as shining shoes, carrying goods, guarding or washing cars, and informal trading. Some may also earn income through begging, or through theft and other illegal activities. At the same time, there are street children who take pride in supporting themselves and their families and who often enjoy their work. Many children may choose entrepreneurship because it allows them a degree of independence, is less exploitative than many forms of paid employment, and is flexible enough to allow them to participate in other activities such as education and domestic tasks.Street Business PartnershipsS.K.I. has worked with partner organisations in Latin America, Africa and India to develop innovative opportunities for street children to earn income.The S.K.I. Bicycle Courier Service first started in the Sudan. Participants in this enterprise were supplied with bicycles, which they used to deliver parcels and messages, and which theywere required to pay for gradually from their wages. A similar program was taken up in Bangalore, India.Another successful project, The Shoe Shine Collective, was a partnership program with the Y.W.C.A. in the Dominican Republic. In this project, participants were lent money to purchase shoe shine boxes. They were also given a safe place to store their equipment, and facilities for individual savings plans.The Youth Skills Enterprise Initiative in Zambia is a joint program with the Red Cross Society and the Y.W.C.A. Street youths are supported to start their own small business through business training, life skills training and access to credit.Lessons learnedThe following lessons have emerged from the programs that S.K.I. and partner organisations have created.•Being an entrepreneur is not for everyone, nor for every street child. Ideally, potential participants will have been involved in the organisation's programs for at least six months, and trust and relationship-building will have already been established.•The involvement of the participants has been essential to the development of relevant programs. When children have had a major role in determining procedures, they are more likely to abide by and enforce them.•It is critical for all loans to be linked to training programs that include the development of basic business and life skills.•There are tremendous advantages to involving parents or guardians in the program, where such relationships exist. Home visits allow staff the opportunity to know where the participants live, and to understand more about each individual's situation.•Small loans are provided initially for purchasing fixed assets such as bicycles, shoe shine kits and basic building materials for a market stall. As the entrepreneurs gain experience, the enterprises can be gradually expanded and consideration can be given to increasing loan amounts. The loan amounts in S.K.I. programs have generally ranged from US$30-$100.•All S.K.I. programs have charged interest on the loans, primarily to get the entrepreneurs used to the concept of paying interest on borrowed money. Generally the rates have been modest (lower than bank rates).ConclusionThere is a need to recognise the importance of access to credit for impoverished young people seeking to fulfil economic needs. The provision of small loans to support the entrepreneurial dreams and ambitions of youth can be an effective means to help them change their lives. However, we believe that credit must be extended in association with other types of support that help participants develop critical life skills as well as productive businesses.Questions 1-4Choose the correct letter, A, B C or D.Write your answers in boxes 1-4 on your answer sheet.1 The quotations in the box at the beginning of the articleA exemplify the effects of S.K.I.B explain why S.K.I. was set up.C outline the problems of street children.D highlight the benefits to society of S.K.I.2 The main purpose of S.K.I. is toA draw the attention of governments to the problem of street children.B provide schools and social support for street children.C encourage the public to give money to street children.D give business training and loans to street children.3 Which of the following is mentioned by the writer as a reason why children end up living on the streets?A unemploymentB warC povertyD crime4 In order to become more independent, street children mayA reject paid employment.B leave their families.C set up their own businesses.D employ other children.Questions 5-8Complete the table below.Choose NO MORE THAN THREE WORDS from Reading Passage 1 for each answer.Write your answers in boxes 5-8 on your answer sheet.Questions 9-12Do the following statements agree with the claims of the writer in Reading Passage 1?In boxes 9-12 on your answer sheet writeYES if the statement agrees with the claims of the wirterNO if the statement contradicts the claims of the writerNOT GIVEN if it is impossible to say what the writer thinks about this9 Any street child can set up their own small business if given enough support.10 In some cases, the families of street children may need financial support from S.K.I.11 Only one fixed loan should be given to each child.12 The children have to pay back slightly more money than they borrowed.Question 13Choose the correct letter, A, B, C or D.Write your answer in box 13 on your answer sheet.The writers conclude that money should only be lent to street childrenA as part of a wider program of aid.B for programs that are not too ambitious.C when programs are supported by local businesses.D if the projects planned are realistic and useful.READING PASSAGE 2You should spend about 20 minutes on Questions 14-26 which are based on Reading Passage 2 on the following pages.Volcanoes-earth-shattering newsWhen Mount Pinatubo suddenly erupted on 9 June 1991, the power of volcanoes past and present again hit the headlinesA Volcanoes are the ultimate earth-moving machinery. A violent eruption can blow the top few kilometres off a mountain, scatter fine ash practically all over the globe and hurl rock fragments into the stratosphere to darken the skies a continent away.But the classic eruption —cone-shaped mountain, big bang, mushroom cloud and surges of molten lava —is only a tiny part of a global story. Vulcanism, the name given to volcanic processes, really has shaped the world. Eruptions have rifted continents, raised mountain chains, constructed islands and shaped the topography of the earth. The entire ocean floor has a basement of volcanic basalt.V olcanoes have not only made the continents, they are also thought to have made the world’s first stable atmosphere and provided all the water for the oceans, rivers and ice-caps. There are now about 600 active volcanoes. Every year they add two or three cubic kilometres of rock to the continents. Imagine a similar number of volcanoes smoking away for the last 3,500 million years. That is enough rock to explain the continental crust.What comes out of volcanic craters is mostly gas. More than 90% of this gas is water vapour from the deep earth: enough to explain, over 3,500 million years, the water in the oceans. The rest of the gas is nitrogen, carbon dioxide, sulphur dioxide, methane, ammonia and hydrogen. The quantity of these gases, again multiplied over 3,500 million years, is enough to explain the mass of the world’s atmosphere. We are alive because volcanoes provided the soil, air and water we need.B Geologists consider the earth as having a molten core, surrounded by a semi-molten mantle and a brittle, outer skin. It helps to think of a soft-boiled egg with a runny yolk, a firm but squishy white and a hard shell. If the shell is even slightly cracked during boiling, the white material bubbles out and sets like a tiny mountain chain over the crack — like an archipelago of volcanic islands such as the Hawaiian Islands. But the earth is so much bigger and the mantle below is so much hotter.Even though the mantle rocks are kept solid by overlying pressure, they can still slowly ‘flow’ like thick treacle. The flow, thought to be in the form of convection currents, is powerful enough to fracture the ‘eggshell’ of the crust into plates, and keep them bumping and grinding againsteach other, or even overlapping, at the rate of a few centimetres a year. These fracture zones, where the collisions occur, are where earthquakes happen. And, very often, volcanoes.C These zones are lines of weakness, or hot spots. Every eruption is different, but put at its simplest, where there are weaknesses, rocks deep in the mantle, heated to 1,350℃, will start to expand and rise. As they do so, the pressure drops, and they expand and become liquid and rise more swiftly.Sometimes it is slow: vast bubbles of magma —molten rock from the mantle —inch towards the surface, cooling slowly, to show through as granite extrusions (as on Skye, or the Great Whin Sill, the lava dyke squeezed out like toothpaste that carries part of Hadrian’s Wall in northern England). Sometimes — as in Northern Ireland, Wales and the Karoo in South Africa — the magma rose faster, and then flowed out horizontally on to the surface in vast thick sheets. In the Deccan plateau in western India, there are more than two million cubic kilometres of lava, some of it 2,400 metres thick, formed over 500,000 years of slurping eruption.Sometimes the magma moves very swiftly indeed. It does not have time to cool as it surges upwards. The gases trapped inside the boiling rock expand suddenly, the lava glows with heat, it begins to froth, and it explodes with tremendous force. Then the slightly cooler lava following it begins to flow over the lip of the crater. It happens on Mars, it happened on the moon, it even happens on some of the moons of Jupiter and Uranus. By studying the evidence, vulcanologists can read the force of the great blasts of the past. Is the pumice light and full of holes? The explosion was tremendous. Are the rocks heavy, with huge crystalline basalt shapes, like the Giant’s Causeway in Northern Ireland? It was a slow, gentle eruption.The biggest eruptions are deep on the mid-ocean floor, where new lava is forcing the continents apart and widening the Atlantic by perhaps five centimetres a year. Look at maps of volcanoes, earthquakes and island chains like the Philippines and Japan, and you can see the rough outlines of what are called tectonic plates — the plates which make up the earth’s crust and mantle. The most dramatic of these is the Pacific ‘ring of fire’ where there have been the most violent explosions — Mount Pinatubo near Manila, Mount St Helen’s in the Rockies and El Chichón in Mexico about a decade ago, not to mention world-shaking blasts like Krakatoa in the Sunda Straits in 1883.D But volcanoes are not very predictable. That is because geological time is not like human time. During quiet periods, volcanoes cap themselves with their own lava by forming a powerful cone from the molten rocks slopping over the rim of the crater; later the lava cools slowly into a huge, hard, stable plug which blocks any further eruption until the pressure below becomes irresistible. In the case of Mount Pinatubo, this took 600 years.Then, sometimes, with only a small warning, the mountain blows its top. It did this at Mont Pelée in Martinique at 7.49 a.m. on 8 May, 1902. Of a town of 28,000, only two people survived. In 1815, a sudden blast removed the top 1,280 metres of Mount Tambora in Indonesia.

They range from a carefully planned, intensive field investigation in a foreign country to a casual introspection about one’s mother tongue carried out in an armchair at home.B In all cases, someone has to act as a source of language data —an informant. Informants are (ideally) native speakers of a language, who provide utterances for analysis and other kinds of information about the language (e.g. translations, comments about correctness, or judgements on usage). Often, when studying their mother tongue, linguists act as their own informants, judging the ambiguity, acceptability, or other properties of utterances against their own intuitions. The convenience of this approach makes it widely used, and it is considered the norm in the generativeapproach to linguistics. But a linguist’s personal judgements are often uncertain, or disagree with the judgements of other linguists, at which point recourse is needed to more objective methods of enquiry, using non-linguists as informants. The latter procedure is unavoidable when working on foreign languages, or child speech.C Many factors must be considered when selecting informants —whether one is working with single speakers (a common situation when languages have not been described before), two people interacting, small groups or large-scale samples. Age, sex, social background and other aspects of identity are important, as these factors are known to influence the kind of language used. The topic of conversation and the characteristics of the social setting (e.g. the level of formality) are also highly relevant, as are the personal qualities of the informants (e.g. their fluency and consistency). For larger studies, scrupulous attention has been paid to the sampling theory employed, and in all cases, decisions have to be made about the best investigative techniques to use.D Today, researchers often tape-record informants. This enables the linguist’s claims about the language to be checked, and provides a way of making those claims more accurate (‘difficult’ pieces of speech can be listened to repeatedly). But obtaining naturalistic, good-quality data is never easy. People talk abnormally when they know they are being recorded, and sound quality can be poor. A variety of tape-recording procedures have thus been devised to minimise the ‘observer’s paradox’ (how to observe the way people behave when they are not being observed). Some recordings are made without the speakers being aware of the fact — a procedure that obtains very natural data, though ethical objections must be anticipated. Alternatively, attempts can be made to make the speaker forget about the recording, such as keeping the tape recorder out of sight, or using radio microphones. A useful technique is to introduce a topic that quickly involves the speaker, and stimulates a natural language style (e.g. asking older informants about how times have changed in their locality).E An audio tape recording does not solve all the linguist’s problems, however. Speech is often unclear and ambiguous. Where possible, therefore, the recording has to be supplemented by the observer’s written comments on the non-verbal behaviour of the participants, and about the context in general. A facial expression, for example, can dramatically alter the meaning of what is said. Video recordings avoid these problems to a large extent, but even they have limitations (the camera cannot be everywhere), and transcriptions always benefit from any additional commentary provided by an observer.F Linguists also make great use of structured sessions, in which they systematically ask their informants for utterances that describe certain actions, objects or behaviours. With a bilingual informant, or through use of an interpreter, it is possible to use translation techniques (‘How do you say table in your language?’). A large number of points can be covered in a short time, using interview worksheets and questionnaires. Often, the researcher wishes to obtain information about just a single variable, in which case a restricted set of questions may be used: a particular feature of pronunciation, for example, can be elicited by asking the informant to say a restricted set of words. There are also several direct methods of elicitation, such as asking informants to fill in the blanks in a substitution frame (e.g. I___ see a car), or feeding them the wrong stimulus for correction (‘Is it possible to say I no can see?’).G A representative sample of language, compiled for the purpose of linguistic analysis, is known as a corpus. A corpus enables the linguist to make unbiased statements about frequency ofusage, and it provides accessible data for the use of different researchers. Its range and size are variable. Some corpora attempt to cover the language as a whole, taking extracts from many kinds of text; others are extremely selective, providing a collection of material that deals only with a particular linguistic feature. The size of the corpus depends on practical factors, such as the time available to collect, process and store the data: it can take up to several hours to provide an accurate transcription of a few minutes of speech. Sometimes a small sample of data will be enough to decide a linguistic hypothesis; by contrast, corpora in major research projects can total millions of words. An important principle is that all corpora, whatever their size, are inevitably limited in their coverage, and always need to be supplemented by data derived from the intuitions of native speakers of the language, through either introspection or experimentation.Questions 27-31Reading Passage 3 has seven paragraphs labeled A-G.Which paragraph contains the following information?Write the correct letter A-G in boxes 27-31 on your answer sheet.NB You may use any letter more than once.27 the effect of recording on the way people talk28 the importance of taking notes on body language29 the fact that language is influenced by social situation30 how informants can be helped to be less self-conscious31 various methods that can be used to generate specific dataQuestions 32-36Complete the table below.Choose NO MORE THAN THREE WORDS from the passage for each answer.Complete the summary of paragraph G below.Choose NO MORE THAN THREE WORDS from the passage for each answer.Write your answers in boxes 37-40 on your answer sheet.A linguist can use a corpus to comment objectively on 37…… .

READING PASSAGE 1You should spend about 20 minutes on Questions 1-14 which are based on Reading Passage 1. Spider silk cuts weight of bridgesA strong, light bio-material made by genes from spiders could transform construction and industry.A Scientists have succeeded in copying the silk-producing gene of the Golden Orb Weaverspider and are using them to create a synthetic material which they believe is the model for a new generation of advanced bio-materials. The new material, biosilk, which has been spun for the first time by researchers at DuPont, has an enormous range of potential uses in construction and manufacturing.B The attraction of the silk spun by the spider is a combination of great strength and enormouselasticity, which man-made fibres have been unable to replicate. On an equal-weight basis, spider silk is far stronger than steel and it is estimated that if a single strand could be made about 10m in diameter, it would be strong enough to stop a jumbo jet in flight. A third important factor is that it is extremely light. Army scientists are already looking at the possibilities of using it for lightweight, bullet-proof vests and parachutes.C For some time, biochemists have been trying to synthesise the drag-line silk of the Golden OrbWeaver. The drag-line silk, which forms the radial arms of the web, is stronger than the other parts of the web and some biochemists believe a synthetic version could prove to be as important a material as nylon, which has been around for 50 years, since the discoveries of Wallace Carothers and his team ushered in the age of polymers.D To recreate the material, scientists, including Randolph Lewis at the University of Wyoming,first examined the silk-producing gland of the spider. "We took out the glands that produce the silk and looked at the coding for the protein material they make, which is spun into a web. We then went looking for clones with the right DNA," he says.E At DuPont, researchers have used both yeast and bacteria as hosts to grow the raw material,which they have spun into fibres. Robert Dorsch, DuPont’s director of biochemical development, says the globules of protein, comparable with marbles in an egg, are harvested and processed. "We break open the bacteria, separate out the globules of protein and use them as the raw starting material. With yeast, the gene system can be designed so that the material excretes the protein outside the yeast for better access," he says.F "The bacteria and the yeast produce the same protein, equivalent to that which the spider usesin the drag lines of the web. The spider mixes the protein into a water-based solution and then spins it into a solid fibre in one go. Since we are not as clever as the spider and we are not using such sophisticated organisms, we substituted man-made approaches and dissolved the protein in chemical solvents, which are then spun to push the material through small holes to form the solid fibre.”G Researchers at DuPont say they envisage many possible uses for a new biosilk material. Theysay that earthquake-resistant suspension bridges hung from cables of synthetic spider silk fibres may become a reality. Stronger ropes, safer seat belts, shoe soles that do not wear out so quickly and tough new clothing are among the other applications. Biochemists such as Lewis see the potential range of uses of biosilk as almost limitless. "It is very strong and retains elasticity; there are no man-made materials that can mimic both these properties. It is also a biological material with all the advantages that has over petrochemicals," he says.H At DuPond’s laboratories, Dorsc h is excited by the prospect of new super-strong materials buthe warns they are many years away. "We are at an early stage but theoretical predictions are that we will wind up with a very strong, tough material, with an ability to absorb shock, which is stronger and tougher than the man-made materials that are conventionally available to us," he says.I The spider is not the only creature that has aroused the interest of material scientists. They havealso become envious of the natural adhesive secreted by the sea mussel. It produces a protein adhesive to attach itself to rocks. It is tedious and expensive to extract the protein from the mussel, so researchers have already produced a synthetic gene for use in surrogate bacteria.Questions 1-5The passage has nine paragraphs A-I.Which paragraph contains the following information?Write the correct letter A-I in boxes 1-5 on your answer sheet.1 a comparison of the ways two materials are used to replace silk-producing glands2 predictions regarding the availability of the synthetic silk3 on-going research into other synthetic materials4 the research into the part of the spider that manufactures silk5 the possible application of the silk in civil engineeringQuestions 6- 11Complete the flow chart below.Choose NO MORE THAN THREE WORDS from the passage for each answer.

Most recently, however, there have been strong moves in both North America and the United Kingdom to develop initiatives that would enhance the profile of the teaching institutions of higher education. In the near future, therefore, as well as the intrinsic rewards gained from working with students and the sense that they are contributing to their overall growth and development, there should soon be extrinsic rewards, in the form of job promotion, for those pursuing academic excellence in teaching in universities.In the future, there will be more focus in universities on the quality of their graduates and their progression rates. Current degree courses, whose assessment strategies require students to learn by rote and reiterate the course material, and which do not require the student to interact with the material, or construct a personal meaning about it or even to understand the discipline, are resulting in poor learning outcomes. This traditional teaching approach does not take into account modern theories of education, the individual needs of the learner, nor his or her prior learning experience.In order for universities to raise both the quality and status of teaching, it is first necessary to have some kind of understanding of what constitutes good practice. A 1995 report, compiled in Australia, lists eight qualities that researchers agree are essential to good teaching.Good teachers...A are themselves good learners - resulting in teaching that is dynamic, reflective and constantlyevolving as they learn more and more about teaching;B display enthusiasm for their subject and the desire to share it with their students;C recognise the importance of context and adjust their teaching accordingly;D encourage deep learning approaches and are concerned with developing their students' criticalthinking skills, problem solving skills and problem-approach behaviours:E demonstrate an ability to transform and extend knowledge, rather than merely transmit it;F recognise individual differences in their students and take advantage of these;G set clear goals, use valid assessment techniques and provide high-quality feedback to theirstudents;In addition to aiming to engage students in the learning process, there is also a need to address the changing needs of the marketplace. Because in many academic disciplines the body of relevant knowledge is growing at an exponential rate, it is no longer possible, or even desirable, for an individual to have a complete knowledge base. Rather, it is preferable that he or she should have an understanding of the concepts and the principles of the subject, have the ability to apply this understanding to new situations and have the wherewithal to seek out the information that is needed.As the world continues to increase in complexity, university graduates will need to be equipped to cope with rapid changes in technology and to enter careers that may not yet be envisaged, with change of profession being commonplace. To produce graduates equipped for this workforce, it is essential that educators teach in ways that encourage learners to engage in deep learning, which may be built upon in the later years of their course, and also be transferred to the workplace.The new role of the university teacher, then, is one that focuses on the students' learning rather than the instructor's teaching. The syllabus is more likely to move from being a set of learning materials made up of lecture notes, to a set of learning materials made up of print, cassettes, disks and computer programs. Class contact hours will cease to be the major determinant of an academic workload. The teacher will then be released from being the sole source of information transmission and will become instead more a learning manager, able to pay more attention to the development and delivery of education rather than content.Student-centred learning activities will also require innovative assessment strategies. Traditional assessment and reporting has aimed to produce a single mark or grade for each student. The mark is intended to indicate three things: the extent to which the learned material was mastered or understood; the level at which certain skills were performed and the degree to which certain attitudes were displayed.A deep learning approach would test a student’s ab ility to identify and tackle new and unfamiliar 'real world' problems. A major assessment goal will be to increase the size and complexity of assignments and minimise what can be achieved by memorising or reproducing content. Wherever possible, students will be involved in the assessment process to assist them to learn how to make judgments about themselves and their work.Questions 15-18Do the following statements agree with the information given in Reading Passage 2?In the boxes 15-18 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 this15Newman believed that the primary focus of universities was teaching.16Job promotion is already used to reward outstanding teaching.17Traditional approaches to assessment at degree level are having a negative effect on the learning process.Questions 19-23Look at the eight qualities A-H of “good teachers” in Reading Passage 2 and the statements below (Questions 19-23).Match each quality to the statement with the same meaning.Write the correct letter A-H in boxes 19-23 on your answer sheet.Good teachers19 can adapt their materials to different learning situations.20 assist students to understand the aims of the course.21 are interested in developing the students as learners.22treat their students with dignity and concern.23continually improve their teaching by monitoring their skills.Questions 24-27Choose the correct letter, A, B, C or DWrite your answers in boxes 24-27 on your answer sheet.24 In the future, university courses will focus more onA developing students’ skills and concepts.B expanding students’ knowledge.C providing work experience for students.D graduating larger numbers of students.25 According to the author, university courses should prepare students toA do a specific job well.B enter traditional professions.C change jobs easily.D create their own jobs.26 The author believes that new learning materials in universities will result inA more work for teachers.B a new role for teachers.C more expensive courses.D more choices for students.27 The author predicts that university assessment techniques will include moreA in-class group assignments.B theoretical exams.C problem-solving activities.D student seminar presentations.READING PASSAGE 3Rising Sea LevelsADuring the night of 1st February 1953, a deadly combination of winds and tide raised the level of the North Sea, broke through the dykes which protected the Netherlands arid inundated farmland and villages as far as 64 km from the coast, killing thousands. For people around the world who inhabit low-lying areas, variations in sea levels are of crucial importance and the scientific study of oceans has attracted increasing attention. Towards the end of the 1970s, some scientists began suggesting that global warming could cause the world's oceans to rise by several metres. The warming, they claimed, was an inevitable consequence of increasing carbon dioxide in the atmosphere which acted like a greenhouse to trap heat in the air. The greenhouse warming was predicted to lead to rises in sea levels in a variety of ways. Firstly, heating the ocean water would cause it to expand. Such expansion might be sufficient to raise the sea level by 300mm in the next 100 years. Then there was the observation that in Europe's Alpine valleys glaciers had been shrinking for the past century. Meltwater from the mountain glaciers might have raised the oceans 50mm over the last 100 years and the rate is likely to increase in future. A third threat is that global warming might cause a store of frozen water in Antarctica to melt which would lead to a calamitous rise in sea level of up to five metres.BThe challenge of predicting how global warming will change sea levels led scientists of several disciplines to adopt a variety of approaches. In 1978 J H Mercer published a largely theoretical statement that a thick slab of ice covering much of West Antarctica is inherently unstable. He suggested that this instability meant that, given just 5 degrees Celsius of greenhouse warming in the south polar region, the floating ice shelves surrounding the West Antarctic ice sheet would begin to disappear. Without these buttresses the grounded ice sheet would quickly disintegrate and coastlines around the world would be disastrously flooded. In evidence Mercer pointed out that between 130,000 and 110,000 years ago there had been just such a global warming as we have had in the past 20,000 years since the last ice age. In the geological remains of that earlier period there are indications that the sea level was five metres above the current sea level- just the level that would be reached if the West Antarctic ice sheet melted. The possibility of such a disastrous rise led a group of American investigators to form SeaRISE (Sea-level Response to Ice Sheet Evolution) in 1990. SeaRISE reported the presence of Five active "ice streams" drawing ice from the interior of West Antarctica into the Ross Sea. They stated that these channels in the West Antarctic ice sheet "may be manifestations of collapse already under way."CBut doubt was cast on those dire warnings by the use of complex computer models of climate. Models of atmospheric and ocean behaviour predicted that greenhouse heating would cause warmer, wetter air to reach Antarctica, where it would deposit its moisture as snow. Thus, the sea ice surrounding the continent might even expand causing sea levels to drop. Other observations have caused scientists working on Antarctica to doubt that sea levels will be pushed upward several metres by sudden melting. For example, glaciologists have discovered that one of the largest ice streams stopped moving about 130 wars ago. Ellen Mosley-Thompson, questioning the SeaRISE theory, notes that ice streams "seem to start and stop, and nobody really knows why." Her own measurements of the rate of snow accumulation near the South Pole show that snowfalls have increased substantially in recent decades as global temperature has increased.DMost researchers are now willing to accept that human activities have contributed to global warming, but no one can say with any assurance whether the Antarctic ice cap is growing or shrinking in response.A satellite being planned by the National Aeronautics and Space Administration will use laser range finders to map changes in the elevation of the polar ice caps, perhaps to within 10 millimetres, and should end the speculation.EWhatever the fate of the polar ice caps may be, most researchers agree that the sea level is currently rising. That, however, is difficult to prove. Tide gauges in ports around the world have been measuring sea levels for decades but the data are flawed because the land to which the gauges are attached can itself be moving up and down. In Stockholm the data from the sea level gauge show the sea level to be falling at four millimetres a year, but that is because all Scandinavia is still rebounding after being crushed by massive glaciers during the last ice age. By contrast, the gauge at Honolulu, which is more stable, shows the sea level to be rising at a rate of one and a half millimetres a year. Unstable regions cannot be omitted from the data because that would eliminate large areas of the world. Most of the eastern seaboard of North America is still settling after a great ice sheet which covered Eastern Canada 20,000 years ago tilted it up. And then there is buckling occurring at the edges of the great tectonic plates as they are pressed against each other. There is also land subsidence as oil and underground water is tapped. In Bangkok, for example, where the residents have been using groundwater, land subsidence makes it appear as if the sea has risen by almost a metre in the past 30 years.FUsing complex calculations on the sea level gauge data, Peltier and Tushingham found that the global sea level has been rising at a rate of 2mm a year over the past few decades. Confirmation came from the TOPEX satellite which used radar altimeters to calculate changes in ocean levels. Steven Nerem, working on the TOPEX data, found an average annual sea level rise of 2mm which is completely compatible with the estimates that have come from 50 years of tide gauge records. The key question still facing researchers is whether this trend will hold steady or begin to accelerate in response to a warming climate. The Intergovernmental Panel on Climate Change gives the broad prediction for the next century of a rise between 200mm and 1 metre.Questions 33 - 40Complete each sentence with the correct ending A-L from the box below.
