Time to cool itFrom The Economist print edition1 REFRIGERATORS are the epitome of clunky technology: solid, reliable and just a little bit dull. They have not changed much over the past century, but then they have not needed to. They are based on a robust and effective idea--draw heat from the thing you want to cool by evaporating a liquid next to it, and then dump that heat by pumping the vapour elsewhere and condensing it. This method of pumping heat from one place to another served mankind well when refrigerators' main jobs were preserving food and, as air conditioners, cooling buildings. Today's high-tech world, however, demands high-tech refrigeration. Heat pumps are no longer up to the job. The search is on for something to replace them.2 One set of candidates are known as paraelectric materials. These act like batteries when they undergo a temperature change: attach electrodes to them and they generate a current. This effect is used in infra-red cameras. An array of tiny pieces of paraelectric material can sense the heat radiated by, for example, a person, and the pattern of the array's electrical outputs can then be used to construct an image. But until recently no one had bothered much with the inverse of this process. That inverse exists, however. Apply an appropriate current to a paraelectric material and it will cool down.3 Someone who is looking at this inverse effect is Alex Mischenko, of Cambridge University. Using commercially available paraelectric film,he and his colleagues have generated temperature drops five times bigger than any previously recorded. That may be enough to change the phenomenon from a laboratory curiosity to something with commercial applications.4 As to what those applications might be, Dr Mischenko is still a little hazy. He has, nevertheless, set up a company to pursue them. He foresees putting his discovery to use in more efficient domestic fridges and air conditioners. The real money, though, may be in cooling computers.5 Gadgets containing microprocessors have been getting hotter for a long time. One consequence of Moore's Law, which describes the doubling of the number of transistors on a chip every 18 months, is that the amount of heat produced doubles as well. In fact, it more than doubles, because besides increasing in number, the components are getting faster. Heat is released every time a logical operation is performed inside a microprocessor, so the faster the processor is, the more heat it generates. Doubling the frequency quadruples the heat output. And the frequency has doubled a lot. The first Pentium chips sold by Dr Moore's company, Intel, in 1993, ran at 60m cycles a second. The Pentium 4--the last "single-core" desktop processor--clocked up 3.2 billion cycles a second.6 Disposing of this heat is a big obstruction to further miniaturisation and higher speeds. The innards of a desktop computer commonly hit 80℃. At 85℃, they stop working. Tweaking the processor's heat sinks (copper or aluminium boxes designed to radiate heat away) has reached its limit. So has tweaking the fans that circulate air over those heat sinks. And the idea of shifting from single-core processors to systems that divided processing power between first two, and then four, subunits, in order to spread the thermal load, also seems to have the endof the road in sight.7 One way out of this may be a second curious physicalphenomenon, the thermoelectric effect. Like paraelectric materials, this generates electricity from a heat source and produces cooling from an electrical source. Unlike paraelectrics, a significant body of researchers is already working on it.8 The trick to a good thermoelectric material is a crystal structure in which electrons can flow freely, but the path of phonons--heat-carrying vibrations that are larger than electrons--is constantly interrupted. In practice, this trick is hard to pull off, and thermoelectric materials are thus less efficient than paraelectric ones (or, at least, than those examined by Dr Mischenko). Nevertheless, Rama Venkatasubramanian, of Nextreme Thermal Solutions in North Carolina, claims to have made thermoelectric refrigerators that can sit on the back of computer chips and cool hotspots by 10℃. Ali Shakouri, of the University of California, Santa Cruz, says his are even smaller--so small that they can go inside the chip.9 The last word in computer cooling, though, may go to a system even less techy than a heat pump--a miniature version of a car radiator. Last year Apple launched a personal computer that is cooled by liquid that is pumped through little channels in the processor, and thence to a radiator, where it gives up its heat to the atmosphere. To improve on this, IBM's research laboratory in Zurich is experimenting with tiny jets that stir the liquid up and thus make sure all of it eventually touches the outside of the channel--the part where the heat exchange takes place. In the future, therefore, a combination of microchannels and either thermoelectrics or paraelectrics might cool computers.

雅思阅读考试模拟测试题带答案
雅思阅读考试模拟测试题带答案2015年雅思阅读考试模拟测试题带答案It is estimated that around of the approximately six thousand languages that are spoken today, over three thousand of them are likely to have disappeared by the year 2100. Many of these are now classified as endangered languages and are classified as such by factors such as the number of speakers a language has, the age of the speakers, and the percentage of the youngest generation acquiring fluency in the language. For example, a language with many tens of thousands of speakers may be considered endangered if the children in the community are no longer learning the language. This scenario may happen in a place like Indonesia which as many different languages in use, but is trying to make communication easier by teaching a national language nation-wide. In another scenario, a language may only have a few hundred speakers but may not be considered endangered because all of the children in the community are learning the language.Once a language is classified as endangered, conservation efforts may be made in an attempt to save or revive the language. Whether or not to make such efforts is a decision which is ultimately made by the speakers of the language themselves, but success often requires a great deal of help and approval from the government or other authorities.One of the most famous language conservation success stories is that of the Welsh language. Historically, large numbers of Welsh people spoke only Welsh, but eventually English became the main language of Wales and fewer and fewer people learned Welsh. Conservation efforts began to be made in themid-20th century with the establishment of such organisations as the Welsh Language Association in 1962. The Welsh Language Act and the Government of Wales Act, both passed in the 1990s, protected the Welsh language and made sure that English and Welsh would have equal status in Wales. Since 2000, the study of the Welsh language has been a compulsory subject in school. Today, over 22% of the population of Wales are Welsh speakers, up from 18% in 1991.Another famous example, Hebrew, is not so much a story of language conservation as much as language revitalisation. Hebrew was once a spoken language but by the 4th century BCE it had been replaced by Aramaic. Hebrew continued to be used for religious purposes and in literature but the language was no longer used for everyday purposes. In the 19th century, there was a movement to revive Hebrew as a spoken language, and when the State of Israel was founded in 1948, Hebrew was adopted as the official language. There was some resistance to this idea, as Hebrew was considered a religious language, not a language to be used for common communication. In addition, because Hebrew was an ancient language, it lacked many of the words that are used in modern times and many new words had to be coined. However, because there was a need for a common language in Israel, the language was accepted and now thrives.The successes of language conservation are many, but many more attempts at language preservation do not succeed and there are many languages that have not survived except for a few recordings made by the last native speakers before their deaths. In some cases, the number of remaining speakers at the start of conservation efforts was not enough to sustain revitalisation, and in others, efforts may fail because there is often no economicbenefit to learning an endangered language at the expense of a more commonly spoken national or international language.QuestionsDo the following statements agree with the information given in the article?In boxes 1-10 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) Half of the languages spoken today will be gone by 2100.2) A language may be considered endangered if children of the speakers are no longer learning the language.3) Indonesian is an endangered language.4) Most endangered languages today are saved and revived.5) Welsh was revived mainly due to government legislature.6) The number of Welsh speakers is expected to rise rapidly in the future.7) All school lessons in Wales are taught in Welsh.8) Hebrew died out completely in the 4th century BCE.9) Hebrew and Aramaic are similar languages.10) Many new terms had to be added to Hebrew to make it functional for today’s world.Answers1) F2) T3) NG4) F5) T6) NG7) NG8) F9) NG10) T【2015年雅思阅读考试模拟测试题带答案】。

它适应力强，能飞善跳，喜爱群居，乐于与人类为伴。
①麻雀的巢如同半个皮球那么大，通常筑在房顶，瓦头檐槽之间的空隙里，也有的筑在灌木或草丛旁，栖息在乡村和公园里的麻雀，很少飞离老家三里之外。
人们常用“自投罗网”形容麻雀的愚蠢。
一位研究麻雀的科学家认为，麻雀在鸟类中是比较聪明的。
在一次实验中，只有3%的麻雀一次被捉，有的麻雀甚至在一旁等待敏捷的小山雀在罗网里把饵叼出来，然后“半路打劫”。
世界著名心理学家波尔特，通过对麻雀的测验，发现它的记忆能力竟能和猴子相比拟。
麻雀虽然在播种时或农作物成熟时糟蹋粮食，但在其他季节及城市里，则是消灭害虫杂草的能手。
特别是在幼雏期，麻雀更是大量捕捉害虫哺养幼雀。
这里有两个例子能说明麻雀的功过：18世纪时，普鲁士国王曾因麻雀啄食他所喜欢吃的桃子，悬赏在全国消灭麻雀。
由于麻雀被捕灭得所剩无几，结果毛虫泛滥成灾。
②19世纪时，美国波士顿的毛虫给庄稼造成了极大的危害。

试题一：阅读下面的短文，回答问题。
The Industrial Revolution, which took place from the late 18th century to the early 19th century, greatly transformed the world, bringing about new technologies and significant changes in the economic and social structures of many countries. One of the key developments during this period was the mechanization of textile production.Prior to the Industrial Revolution, textile production was a labor-intensive process, with spinning and weaving done by hand. However, with the invention of the spinning jenny and the power loom, the production process became much more efficient and less time-consuming. This led to the establishment of textile factories and the mass production of cloth, which in turn fueled the growth of industrialization.The spinning jenny, invented by James Hargreaves in 1764, allowed a single worker to simultaneously spin multiple spools of thread. This greatly increased the productivity of the spinning process. Similarly, the power loom, invented by Edmund Cartwright in 1785, automated the process ofweaving, reducing the need for skilled labor and further increasing production capacity.The mechanization of textile production had profound effects on various aspects of society. Firstly, it significantly lowered the cost of textiles, making them more affordable and accessible to a larger population. This led to an increase in the standard of living for many people, as they were able to dress themselves, their families, and their homes with quality fabrics at a lower cost. Secondly, it created a demand for raw materials such as cotton, which in turn drove the expansion of colonial territories. Finally, it also resulted in the growth of urban areas, as textile factories were built in cities to take advantage of the power supply and transportation networks.Question 1: What was one of the key developments during the Industrial Revolution?Question 2: Who invented the spinning jenny?Question 3: How did the mechanization of textile production affect society?答案一：Question 1: The mechanization of textile production.Question 2: James Hargreaves.Question 3: It lowered the cost of textiles, increased the standard of living, stimulated the demand for raw materials, and contributed to urban growth.试题二：阅读下面的短文，选择正确的答案。

Large sample international comparisons of pupils’ attainments since the 1960s have established that not only did Japanese pupils at age13 have better scores of average attainment, but there was alsoa larger proportion of ‘low’ attainers in England, where, incidentally, the variation in attainment scores was much greater. The percentage of Gross National Product spent on education is reasonably similar in the two countries, so how is this higher and more consistent attainment in maths achieved?B Lower secondary schools in Japan cover three school years, from the seventh grade (age 13) to the ninth grade (age 15). Virtually all pupils at this stage attend state schools: only 3 per cent are in the private sector. Schools are usually modern in design, set well back from the road and spacious inside. Classrooms are large and pupils sit at single desks in rows. Lessons last for a standardised 50 minutes and are always followed by a 10-minute break, which gives the pupils a chance to let off steam. Teachers begin with a formal address and mutual bowing, and then concentrate on whole-class teaching.Classes are large — usually about 40 — and are unstreamed. Pupils stay in the same class for all lessons throughout the school and develop considerable class identity and loyalty. Pupils attend the school in their own neighbourhood, which in theory removes ranking by school. In practice in T okyo, because of the relative concentration of schools, there is some competition to get into the ‘better’ school in a particular area.C Traditional ways of teaching form the basis of the lessonand the remarkably quiet classes take their own notes of the points made and the examples demonstrated. Everyone has their own copy of the textbook supplied by the central education authority, Monbusho, as part of the concept of free compulsory education up to the age of 15. These textbooks are, on the whole, small, presumably inexpensive to produce, but well set out and logically developed. (One teacher was particularly keen to introduce colour and pictures into maths textbooks: he felt this would make them more accessible to pupils brought up in a cartoon culture.) Besides approving textbooks, Monbusho also decides the highly centralised national curriculum and how it is to be delivered.D Lessons all follow the same pattern. At the beginning, the pupils put solutions to the homework on the board, then the teachers comment, correct or elaborate as necessary. Pupils mark their own homework: this is an important principle in Japanese schooling as it enables pupils to see where and why they made a mistake, so that these can be avoided in future. No one minds mistakes or ignorance as long as you are prepared to learn from them.After the homework has been discussed, the teacher explains the topic of the lesson, slowly and with a lot of repetition and elaboration. Examples are demonstrated on the board; questions from the textbook are worked through first with the class, and then the class is set questions from the textbook to do individually. Only rarely are supplementary worksheets distributed in a maths class. The impression is that the logical nature of the textbooks and their comprehensive coverage of different types of examples, combined with the relative homogeneity of the class, renders work sheets unnecessary. Atthis point, the teacher would circulate and make sure that all the pupils were coping well.E It is remarkable that large, mixed-ability classes could be kept together for maths throughout all their compulsory schooling from 6 to 15. Teachers say that they give individual help at the end of a lesson or after school, setting extra work if necessary. In observed lessons, any strugglers would be assisted by the teacher or quietly seek help from their neighbour. Carefully fostered class identity makes pupils keen to help each other — anyway, it is in their interests since the class progresses together.This scarcely seems adequate help to enable slow learners to keep up. However, the Japanese attitude towards education runs along the lines of ‘if you work hard enough, you can do almost anything’. Parents are kept closely informed of their children’s progress and will play a part in helping their children to keep up with class, s ending them to ‘Juku’ (private evening tuition) if extra help is needed and encouraging them to work harder. It seems to work, at least for 95 per cent of the school population.F So what are the major contributing factors in the success of maths teaching? Clearly, attitudes are important. Education is valued greatly in Japanese culture; maths is recognised as an important compulsory subject throughout schooling; and the emphasis is on hard work coupled with a focus on accuracy.Other relevant points relate to the supportive attitude of a class towards slower pupils, the lack of competition within a class, and the positive emphasis on learning for oneself and improving one’s own standard.

Apart from engendering widespread ecological disorders, pesticides have contributed to the emergence of a new breed of chemical-resistant, highly lethal superbugs.According to a recent study by the Food and Agriculture Organisation (FAO), more than 300 species of agricultural pests have developed resistance to a wide range of potent chemicals. Not to be left behind are the disease-spreading pests, about 100 species of which have become immune to a variety of insecticides now in use.One glaring disadvantage of pesticides’ application is that,while destroying harmful pests, they also wipe out many useful non-targeted organisms, which keep the growth of the pest population in check. This results in what agroecologists call the ‘treadmill syndrome’. Because of their tremendous breeding potential and genetic diversity, many pests are known to withstand synthetic chemicals and bear offspring with a built-in resistance to pesticides.The havoc that the ‘treadmill syndrome’ can bring about is well illustrated by what happened to cotton farmers in Central America. In the early 1940s, basking in the glory of chemical-based intensive agriculture, the farmers avidly took to pesticides as a sure measure to boost crop yield. The insecticide was applied eight times a year in the mid-1940s, rising to 28 in a season in the mid-1950s, following the sudden proliferation of three new varieties of chemical-resistant pests.By the mid-1960s, the situation took an alarming turn with the outbreak of four more new pests, necessitating pesticide spraying to such an extent that 50% of the financial outlay on cotton production was accounted for by pesticides. In the early 1970s, the spraying frequently reached 70 times a season as the farmers were pushed to the wall by the invasion of genetically stronger insect species.Most of the pesticides in the market today remain inadequately tested for properties that cause cancer and mutations as well as for other adverse effects on health, says a study by United States environmental agencies. The United States National Resource Defense Council has found that DDT was the most popular of a long list of dangerous chemicals in use.In the face of the escalating perils from indiscriminate applications of pesticides, a more effective and ecologicallysound strategy of biological control, involving the selective use of natural enemies of the pest population, is fast gaining popularity — though, as yet, it is a new field with limited potential. The advantage of biological control in contrast to other methods is that it provides a relatively low-cost, perpetual control system with a minimum of detrimental side-effects. When handled by experts, bio-control is safe, non-polluting and self-dispersing.The Commonwealth Institute of Biological Control (CIBC) in Bangalore, with its global network of research laboratories and field stations, is one of the most active, non-commercial research agencies engaged in pest control by setting natural predators against parasites. CIBC also serves as a clearing-house for the export and import of biological agents for pest control world-wide.CIBC successfully used a seed-feeding weevil, native to Mexico, to control the obnoxious parthenium weed, known to exert devious influence on agriculture and human health in both India and Australia. Similarly the Hyderabad-based Regional Research Laboratory (RRL), supported by CIBC, is now trying out an Argentinian weevil for the eradication of water hyacinth, another dangerous weed, which has become a nuisance in many parts of the world. According to Mrs Kaiser Jamil of RRL, ‘The Argentinian weevil does not attack any other plant and a pair of adult bugs could destroy the weed in 4-5 days.’ CIBC is also perfecting the technique for breeding parasites that prey on ‘disapene scale’ insects — notorious defoliants of fruit trees in the US and India.How effectively biological control can be pressed into service is proved by the following examples. In the late 1960s, when Sri Lanka’s flouri shing coconut groves were plagued by leaf-mininghispides, a larval parasite imported from Singapore brought the pest under control. A natural predator indigenous to India, Neodumetia sangawani, was found useful in controlling the Rhodes grass-scale insect that was devouring forage grass in many parts of the US. By using Neochetina bruci, a beetle native to Brazil, scientists at Kerala Agricultural University freed a 12-kilometre-long canal from the clutches of the weed Salvinia molesta, popularly called ‘African Payal’ in Kerala. About 30,000 hectares of rice fields in Kerala are infested by this weed.Questions 14-17Choose the correct letter, A, B, C, or D.Write the correct letter in boxes 14-17 on your answer sheet.14 The use of pesticides has contributed toA a change in the way ecologies are classified by agroecologists.B an imbalance in many ecologies around the world .C the prevention of ecological disasters in some parts of the the world .D an increase in the range of ecologies which can be usefully farmed.15 The Food and Agriculture Organisation has counted more than 300 agricultural pests whichA are no longer responding to most pesticides in use.B can be easily controlled through the use of pesticides.C continue to spread disease in a wide range of crops.D may be used as part of bio-control’s replacement of pesticides.16 Cotton farmers in Central America began to use pesticidesA because of an intensive government advertising campaign.B in response to the appearance of new varieties of pest.C as a result of changes in the seasons and the climate.D to ensure more cotton was harvested from each crop.17 By the mid-1960s, cotton farmers in Central America found that pesticidesA were wiping out 50% of the pests plaguing the crops.B were destroying 50% of the crop they were meant to protect.C were causing a 50% increase in the number of new pests reported.D were costing 50% of the total amount they spent on their crops.Questions 18-21Do the following statements agree with the claims of the writer in Reading Passage 2?In boxes 18-21 on your answer sheet, writeYES if the statement agrees with the claims of the writerNo if the statement contradicts the claims of the writerNOT GIVEN if it impossible to say what the write thinks about this18 Disease-spreading pests respond more quickly to pesticides than agricultural pests do.19 A number of pests are now born with an innate immunity to some pesticides.20 Biological control entails using synthetic chemicals to try and change the genetic make-up of the pests’ offspring.21 Bio-control is free from danger under certain circumstances.Questions 22-26Complete each sentence with the correct ending, A-I, below.Write the correct letter, A-I, in boxes 22-26 on your answersheet.22 Disapene scale insects feed on23 Neodumetia sangawani ate24 Leaf-mining hispides blighted25 An Argentinian weevil may be successful in wiping out26 Salvinia molesta plaguesA forage grass.B rice fields.C coconut trees.D fruit trees.E water hyacinth.F parthenium weed.G Brazilian beetles.H grass-scale insects.I larval parasites.READING PASSAGE 3You should spend about 20 minutes on Questions 27-40, which are based on Reading Passage 3 below.Collecting Ant SpecimensCollecting ants can be as simple as picking up stray ones and placing them in a glass jar, or as complicated as completing an exhaustive survey of all species present in an area and estimating their relative abundances. The exact method used will depend on the final purpose of the collections. For taxonomy, or classification, long series, from a single nest, which contain all castes (workers, including majors and minors, and, if present, queens and males) are desirable, to allow the determination of variation within species. For ecological studies, the most important factor is collecting identifiable samples of as many of the different species present as possible. Unfortunately, thesemethods are not always compatible. The taxonomist sometimes overlooks whole species in favour of those groups currently under study, while the ecologist often collects only a limited number of specimens of each species, thus reducing their value for taxonomic investigations.To collect as wide a range of species as possible, several methods must be used. These include hand collecting, using baits to attract the ants, ground litter sampling, and the use of pitfall traps. Hand collecting consists of searching for ants everywhere they are likely to occur. This includes on the ground, under rocks, logs or other objects on the ground, in rotten wood on the ground or on trees, in vegetation, on tree trunks and under bark. When possible, collections should be made from nests or foraging columns and at least 20 to 25 individuals collected. This will ensure that all individuals are of the same species, and so increase their value for detailed studies. Since some species are largely nocturnal, collecting should not be confined to daytime. Specimens are collected using an aspirator (often called a pooter), forceps, a fine, moistened paint brush, or fingers, if the ants are known not to sting. Individual insects are placed in plastic or glass tubes (1.5-3.0 ml capacity for small ants, 5-8 ml for larger ants) containing 75% to 95% ethanol. Plastic tubes with secure tops are better than glass because they are lighter, and do not break as easily if mishandled.Baits can be used to attract and concentrate foragers. This often increases the number of individuals collected and attracts species that are otherwise elusive. Sugars and meats or oils will attract different species and a range should be utilised. These baits can be placed either on the ground or on the trunks of trees or large shrubs. When placed on the ground, baits should besituated on small paper cards or other flat, light-coloured surfaces, or in test-tubes or vials. This makes it easier to spot ants and to capture them before they can escape into the surrounding leaf litter.Many ants are small and forage primarily in the layer of leaves and other debris on the ground. Collecting these species by hand can be difficult. One of the most successful ways to collect them is to gather the leaf litter in which they are foraging and extract the ants from it. This is most commonly done by placing leaf litter on a screen over a large funnel, often under some heat. As the leaf litter dries from above, ants (and other animals) move downward and eventually fall out the bottom and are collected in alcohol placed below the funnel. This method works especially well in rain forests and marshy areas. A method of improving the catch when using a funnel is to sift the leaf litter through a coarse screen before placing it above the funnel. This will concentrate the litter and remove larger leaves and twigs. It will also allow more litter to be sampled when using a limited number of funnels.The pitfall trap is another commonly used tool for collecting ants. A pitfall trap can be any small container placed in the ground with the top level with the surrounding surface and filled with a preservative. Ants are collected when they fall into the trap while foraging. The diameter of the traps can vary from about 18 mm to 10 cm and the number used can vary- from a few to several hundred. The size of the traps used is influenced largely by personal preference (although larger sizes are generally better), while the number will be determined by the study being undertaken. The preservative used is usually ethylene glycol or propylene glycol, as alcohol will evaporate quickly and the trapswill dry out. One advantage of pitfall traps is that they can be used to collect over a period of time with minimal maintenance and intervention. One disadvantage is that some species are not collected as they either avoid the traps or do not commonly encounter them while foraging.Questions 27-30Do the following statements agree with the information given in Reading Passage 3?In boxes 27-30 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 this27 Taxonomic research involves comparing members of one group of ants.28 New species of ants are frequently identified by taxonomists.29 Range is the key criterion for ecological collections.30 A single collection of ants can generally be used for both taxonomic and ecological purposes.Questions 31-36Classify the following statements as referring toA hand collectingB using baitC sampling ground litterD using a pitfall trapWrite the correct letter, A,B,C or D, in boxes 31-36 on your answer sheet.31 It is preferable to take specimens from groups of ants.32 It is particularly effective for wet habitats.33 It is a good method for species which are hard to find.34 Little time and effort is required.35 Separate containers are used for individual specimens.36 Non-alcoholic preservative should be used.Questions 37-40Label the diagram below.Choose NO MORE THAN TWO WORDS from the passage for each answer.Write your answers in boxes 37-40 on your answer sheet.剑桥雅思阅读8原文参考译文(test4)PASSAGE 1 参考译文：数学崛起之地A.就数学的平均成绩而言，日本的纪录要比英格兰和威尔士好得多。

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

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

Neoclassical economics is built on the assumption that humans are rational beings who have a clear idea of their best interests and strive to extract maximum benefit from any situation . Neoclassical economics assumes that the process of decision - making is rational . But that contradicts growing evidence that decision - making draws on the emotionseven when reason is clearly involved .B . The role of emotions in decisions makes perfect sense . For situations met frequently in the past ， such as obtaining food and mates ， and confronting or fleeing from threats ， the neural mechanisms required to weigh up the pros and cons will have been honed by evolution to produce an optimal outcome . Since emotion is the mechanism by which animals are prodded towards such outcomes ，evolutionary and economic theory predict the same practical consequences for utility in these cases . But does this still apply when the ancestral machinery has to respond to the stimuli of urban modernity ?C . One of the people who thinks that it does not is George Loewenstein ， an economist at Carnegie Mellon University ， in Pittsburgh . In particular ， he suspects that modern shopping has subverted the decision - making machinery in a way that encourages people to run up debt . To prove the point he has teamed up with two psychologists ， Brian Knutson of Stanford University and Drazen Prelec of the Massachusetts Institute of Technology ， to look at what happens in the brain when it is deciding what to buy .。
雅思阅读考试模拟试练习题及答案解析
雅思阅读考试模拟试练习题及答案解析Time to cool itFrom The Economist print edition1 REFRIGERATORS are the epitome of clunky technology: solid, reliable and just a little bit dull. They have not changed much over the past century, but then they have not needed to. They are based on a robust and effective idea--draw heat from the thing you want tocool by evaporating a liquid next to it, and then dump that heat by pumping the vapour elsewhere and condensing it. This method of pumping heat from one place to another served mankind well when refrigerators' main jobs were preserving food and, as air conditioners, cooling buildings. Today's high-tech world, however, demands high-tech refrigeration. Heat pumps are no longer up to the job. The search is on for something to replace them.2 One set of candidates are known as paraelectric materials. These act like batteries when they undergo a temperature change: attach electrodes to them and they generate a current. This effect is used in infra-red cameras. An array of tiny pieces of paraelectric material can sense the heat radiated by, for example, a person, and the pattern of the array's electrical outputs can then be used to construct an image. But until recently no one had bothered much with the inverse of this process. That inverse exists, however. Apply an appropriate current to a paraelectric material and it will cool down.3 Someone who is looking at this inverse effect is Alex Mischenko, of Cambridge University. Using commercially available paraelectric film, he and his colleagues have generated temperature drops five times bigger than any previously recorded. That may be enough to change the phenomenon from a laboratory curiosity to something with commercial applications.4 As to what those applications might be, Dr Mischenko is still a little hazy. He has, nevertheless, set up a company to pursue them.He foresees putting his discovery to use in more efficient domestic fridges and air conditioners. The real money, though, may be in cooling computers.5 Gadgets containing microprocessors have been getting hotter fora long time. One consequence of Moore's Law, which describes the doubling of the number of transistors on a chip every 18 months, is that the amount of heat produced doubles as well. In fact, it more than doubles, because besides increasing in number, the componentsare getting faster. Heat is released every time a logical operationis performed inside a microprocessor, so the faster the processor is, the more heat it generates. Doubling the frequency quadruples theheat output. And the frequency has doubled a lot. The first Pentium chips sold by Dr Moore's company, Intel, in 1993, ran at 60m cycles a second. The Pentium 4--the last "single-core" desktop processor--clocked up 3.2 billion cycles a second.6 Disposing of this heat is a big obstruction to further miniaturisation and higher speeds. The innards of a desktop computer commonly hit 80℃. At 85℃, they stop working. Tweaking theprocessor's heat sinks (copper or aluminium boxes designed to radiate heat away) has reached its limit. So has tweaking the fans that circulate air over those heat sinks. And the idea of shifting from single-core processors to systems that divided processing power between first two, and then four, subunits, in order to spread the thermal load, also seems to have the end of the road in sight.7 One way out of this may be a second curious physical phenomenon, the thermoelectric effect. Like paraelectric materials, thisgenerates electricity from a heat source and produces cooling from an electrical source. Unlike paraelectrics, a significant body of researchers is already working on it.8 The trick to a good thermoelectric material is a crystal structure in which electrons can flow freely, but the path ofphonons--heat-carrying vibrations that are larger than electrons--is constantly interrupted. In practice, this trick is hard to pull off, and thermoelectric materials are thus less efficient thanparaelectric ones (or, at least, than those examined by Dr Mischenko). Nevertheless, Rama Venkatasubramanian, of Nextreme Thermal Solutionsin North Carolina, claims to have made thermoelectric refrigerators that can sit on the back of computer chips and cool hotspots by 10℃. Ali Shakouri, of the University of California, Santa Cruz, says his are even smaller--so small that they can go inside the chip.9 The last word in computer cooling, though, may go to a system even less techy than a heat pump--a miniature version of a car radiator. Last year Apple launched a personal computer that is cooled by liquid that is pumped through little channels in the processor,and thence to a radiator, where it gives up its heat to the atmosphere. To improve on this, IBM's research laboratory in Zurichis experimenting with tiny jets that stir the liquid up and thus make sure all of it eventually touches the outside of the channel--thepart where the heat exchange takes place. In the future, therefore, a combination of microchannels and either thermoelectrics or paraelectrics might cool computers. The old, as it were, hand in hand with the new.(830 words)Questions 1-5Complete each of the following statements with the scientist or company name from the box below.Write the appropriate letters A-F in boxes 1-5 on your answer sheet.A.

雅思阅读模拟及答案解析
雅思阅读模拟及答案解析雅思阅读模拟及答案解析How shops can exploit people's herd mentality to increase sales1. A TRIP to the supermarket may not seem like an exercise in psychological warfare—but it is. Shopkeepers know that filling a store with the aroma of freshly baked bread makes people feel hungry and persuades them to buy more food than they had intended. Stocking the most expensive products at eye level makes them sell faster than cheaper but less visible competitors. Now researchers are investigating how “swarm intelligence” (that is, how ants, bees or any social animal, including humans, behave in a crowd) can be used to influence what people buy.2. At a recent conference on the simulation of adaptive behaviour in Rome, Zeeshan-ul-hassan Usmani, a computer scientist from the Florida Institute of T echnology, described a new way to increase impulse buying using this phenomenon. Supermarkets already encourage shoppers to buy things they did not realise they wanted: for instance, by placing everyday items such as milk and eggs at the back of the store, forcing shoppers to walk past other tempting goods to reach them. Mr Usmani and Ronaldo Menezes, also of the Florida Institute of Technology, set out to enhance this tendency to buy more by playing on the herd instinct. The idea is that, if a certain product is seen to be popular, shoppers are likely to choose it too. The challenge is to keep customers informed about what others are buying.3. Enter smart-cart technology. In Mr Usmani's supermarket every product has a radio frequency identification tag, a sort of barcode that uses radio waves to transmit information, and everytrolley has a scanner that reads this information and relays it to a central computer. As a customer walks past a shelf of goods, a screen on the shelf tells him how many people currently in the shop have chosen that particular product. If the number is high, he is more likely to select it too.4. Mr Usmani's "swarm-moves" model appeals to supermarkets because it increases sales without the need to give people discounts. And it gives shoppers the satisfaction of knowing that they bought the "right" product—that is, the one everyone else bought. The model has not yet been tested widely in the real world, mainly because radio frequency identification technology is new and has only been installed experimentally in some supermarkets. But Mr Usmani says that both Wal-Mart in America and Tesco in Britain are interested in his work, and testing will get under way in the spring.5. Another recent study on the power of social influence indicates that sales could, indeed, be boosted in this way. Matthew Salganik of Columbia University in New York and his colleagues have described creating an artificial music market in which some 14,000 people downloaded previously unknown songs. The researchers found that when people could see the songs ranked by how many times they had been downloaded, they followed the crowd. When the songs were not ordered by rank, but the number of times they had been downloaded was displayed, the effect of social influence was still there but was less pronounced. People thus follow the herd when it is easy for them to do so.6. In Japan a chain of convenience shops called RanKing RanQueen has been ordering its products according to sales data from department stores and research companies. The shops sellonly the most popular items in each product category, and the rankings are updated weekly. Icosystem, a company in Cambridge, Massachusetts, also aims to exploit knowledge of social networking to improve sales.7. And the psychology that works in physical stores is just as potent on the internet. Online retailers such as Amazon are adept at telling shoppers which products are popular with like-minded consumers. Even in the privacy of your home, you can still be part of the swarm.Questions 1-6Complete the sentences below with words taken from the reading passage. Use NO MORE THAN THREE WORDS for each answer.1. Shopowners realize that the smell of _______________ can increase sales of food products.2. In shops, products shelved at a more visible level sell better even if they are more _______________.3.

On the way to everyday items at the back of the store, shoppers might be tempted to buy _______________.5. If the number of buyers shown on the _______________ is high, other customers tend to follow them.6. Using the "swarm-moves" model, shopowners do not have to give customers _______________ to increase sales.Questions 7-12Do the following statements agree with the information given in the reading passage? For questions 7-12 write YES if the statement agrees with the informationNO if the statement contraicts the informationNOT GIVEN if there is no information on this in the passage7.

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