雅思课堂阅读分析总结(长难句)
Reading 1:A remarkable Beetle1.easier to control than buffalo flies【not given】-原文（第二段）：Ausrealia’s native dung beetles are scrub and woodland dwellers,specializing in couase marsupial droppings(粪便) and avoiding the soft cattle dung in which bush flies and bufflo flies breed.[澳洲本土的蜣螂生活在灌木丛和林地里，特别喜欢吃有袋动物的粪便，不吃灌木蝇和水牛蝇繁殖的软牛粪。
]-分析：原文并没有提到灌木蝇和水牛蝇控制的难易之分，因此答案为not given。
2.of dung beetle were initiallybrought to Australia by the CSIRO(由CSIRO带到澳大利亚,brought to A by B 由B带到A).【no】-原文(根据CSIRO定位至第3段)：Between 1968 and 1982,the CSIRO imported insects from about 50 different species of dung beetle,from Asia, Europe and Africa,aiming to match them to different climatic zones in Australia.-分析：由原文知从1968年到1982年，CSIRO从亚洲、欧洲和非洲进口了大约50种不同种类的蜣螂，目的是让它们适应澳大利亚不同的气候区。
而不是题目中的4000种蜣螂，故答案为no。
3.题目：Dung beetles were brought to Australia by the CSIRO over a fourteen-year period.【yes】-原文：Between 1968 and 1982,the CSIRO imported insects from about 50 different species of dung beetle,from Asia, Europe and Africa,aiming to match them to different climatic zones in Australia.-分析：1968至1982为14年，题目和原文相符合，故答案为yes。

解析雅思阅读之分析长难句答案1.An alternative to this notion of genetic programming is to see theteacher-subjects’ actions as a result of the social environment under which the experiment was carried out.2.An action such as shocking a victim, which in isolation appears evil, acquiresa completely different meaning when placed in this setting.3.Here we have two radically different explanations for why so manyteacher-subjects were willing to forgo their sense of personal responsibility for the sake of an institutional authority figure.4.That would matter less if people applied the same degree of skepticism toenvironmental lobbying as they do to lobby groups in other fields.5.One form of pollution –the release of greenhouse gases that causes globalwarming –does appear to be a phenomenon that is going to extend well into our future, but its total impact is unlikely to posea devastating problem.6.Thus, in this explanation the subject merges his unique personality andpersonal 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.7. A modern hard-core sociobiologist might even go so far as to claim that thisaggressive 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 carves, ultimately finding its way into our genetic make-up as a remnant of our ancient animal ways.8.Yet opinion polls suggest that many people nurture the belief thatenvironmental standards are declining and four factors seem to cause this disjunction between perception and reality.9.Yet a green organization opposing such a weakening is seen as altruistic,even if an impartial view of the control in question might suggest they are doing more harm than good.10.People worry that the endless rise in the amount of stuff everyone throwsaway will cause the world to run out of places to dispose of waste.11.Yet, even if America’s tras h output continues to rise as it has done in thepast, 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.。

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