精品文档General English Admission Test For Non-English Major Ph.D. program(Harbin Institute of Technology) 第一套Part I Reading Comprehension (40 points)Passage 1Questions 1-5 are bashed on the following passage. The planets last intact expanses of forest are under siege. Eight thousand years ago, forests covered more than 23 million square miles, or about 40 percent of Earths land surface. Today, almost half of those forests have fallen to the ax, the chain saw, the matchstick, or the bulldozer. A map unveiled in March by the Washington-based World Resources Institute not only shows the locations of former forests, but also assesses the condition of todays forests worldwide. Institute researchers developed the map with the help of the World Conservation Monitoring Center, the World Wildlife Fund, and 90 forest experts at a variety of universities, government organizations, and environmental groups. Only one-fifth of the remaining forests are still “frontier forests,” defined as relatively undisturbed natural forests large enough to support all of their native species. Frontier forests offer a number of benefits: They generate and maintain biodiversity, protect watersheds, prevent flooding and soil erosion, and stabilize climate. Many large areas that have traditionally been classified as forest land dont qualify as “frontier” because of human influences such as fire suppression and a patchwork of logging. “Theres surprisingly little intact forest left,” says research associate Dirk Bryant, the principal author of the report that accompanies the new map. In the report, Bryant, Daniel Nielsen, and Laura Tangley divide the world into four groups:76 countries that have lost all of their frontier forest; 11 nations that are “on the edge”; 28 countries with “not much time”; and only eight-including Canada, Russia, and Brazil-that still have a “great opportunity” to keep most of their original forest. The United States is among the nations said to be running out of time: In the lower 48 states, says Bryant, “great opportunity” to keep most of their original forest. The United States is among the nations said to be running out of time: In the lower48 states, says Bryant, “only 1 percent of the forest that was once there as frontier forest qualifies today.”Logging poses the biggest single threat to remaining frontier forests. “Our results suggest that 70 percent of frontier forests under threat are threatened by logging,” says Bryant. The practice of cutting timber also creates roads that cause erosion and open the forest to hunting, mining, firewood gathering, and land clearing for farms.What can protect frontier forests? The researchers recommend combining preservation with sustainable land use practices such as tourism and selective timber extraction. “Its possible to restore frontiers,” says Bryant, “but the cost and time required to do so would suggest that the smart approach is to husband the remaining frontier forest before its gone.”1. What is the main idea of the passage?A. The present situation of frontier forest on Earth.B. The history of ecology.C. The forest map in the past.D. Beautiful forests in different parts of the world.2. The word “unveiled” in paragraph 2 is closest in meaning to _.A. evaluated B. decoratedC. designed D. made public3. Frontier forests have which of the following benefits?A. They keep climate stable.B. They enhance timber industry.C. They provide people with unique scenery.D. They are of various types.4. The phrase “on the edge” in Paragraph 5 probably means_.A surrounded by frontier forest B near frontier forestC about to lose their frontier forest D under pressure5. According to the passage, roads created by timber-cutting make it possible for people to_. A travel to other places through the short cutB exploit more forest land C find directions easily D protect former forestsPassage 2Questions 6-10 are based on the following passage.（2005年9月PETS3真题）To get a chocolate out of a box requires a considerable amount of unpacking: the box has to be taken out of the paper bag in which it arrived the cellophane wrapper has to be torn off, the lip opened and removed; the lid opened and the paper removed; the chocolate itself then has to be unwrapped from its own piece of paper. But this insane amount of wrapping is not confined to luxuries: it is now becoming increasingly difficult to buy anything that is not done up in cellophane, polythene, or paper.The package itself is of no interest to the shopper, who usually throws it away immediately. Useless wrapping accounts for much of the refuse put our by the average London household each week. So why is it done? Some of it, like the cellophane on meat, is necessary, but most of the rest is simply competitive selling. This is absurd. Packaging is using up scarce energy and resources and messing up the environment.Little research is being carried out on the costs of alternative types of packaging. Just how possible is it, for instance, for local authorities to salvage paper, pulp it, and recycle it as egg-boxes? Would it be cheaper to plant another forest? Paper is the material most used for packaging-20 million paper bags are apparently used in Great Britain each day -but very little is salvaged.A machine has been developed that pulps paper, and then processes it into packaging, e.g. egg-boxes and cartons. This could be easily adapted for local authority use. It would mean that people would have to separate their refuse into paper and non-paper, with a different dustbin for each. Paper is, in fact, probably the material that can be most easily recycled; and now, with massive increases in paper prices, the time has come at which collection by local authorities could be profitable.Recycling of this kind is already happening with milk bottles, which are returned to the dairies, and it has been estimated that if all the milk bottles necessary were made of plastic, then British dairies would be producing the equivalent of enough plastic tubing to encircle the earth every five or six days!The trouble with plastic is that it does not rot. Some environmentalists argue that the only solution to the problem of ever growing mounds of plastic containers is to do away with plastic altogether in the shops, a suggestion unacceptable to many manufacturers who say there is no alternative to their handy plastic packs. It is evident that more research is needed into the recovery and reuse of various materials and into the cost of collecting and recycling containers as opposed to producing new ones. Unnecessary packaging, intended to be used just once, and making things look better so more people will buy them, is clearly becoming increasingly absurd. But it is not so much a question of doing away with packaging as resources for what is, after all, a relatively unimportant function.6. The sentence “This insane amount of wrapping is not confined to luxuries” means that_.A not enough wrapping is used for luxuriesB more wrapping is used for luxuries than for ordinary productsC it is not only for luxury products that too much wrapping is used D the wrapping used for luxury products is unnecessary7. The local authorities are_. A the Town CouncilB the policeC the paper manufacturersD the most influential citizens8 If paper is to be recycled,_. A more forests will have to be planted B the use of paper bags will have to be restrictedC people will have to use different dustbins for their rubbish D the local authorities will have to reduce the price of paper9. British dairies are_. A producing enough plastic tubing to go round the world in less than a week B giving up the use of glass bottles C increasing the production of plastic bottles D reusing their old glass bottles10. The environmentalists think that_. A more plastic packaging should be used B plastic is the most convenient form of packaging C too much plastic is wastedD shops should stop using plastic containersPassage 3Questions11-18 are based on the following passage.（找到了出处）The tragic impact of the modern city on the human being has killed his sense of aesthetics, the material benefits of an affluent society have diverted his attention from aesthetics, the material benefits of an affluent society have diverted his attention from his city and its cultural potentials to the products of science and technology: washing machines, central heating, automatic cookers, television sets, computers and fitted carpets, He is, at the moment, drunk with democracy, well-to-do, a car driver, and has never had it so good.He is reluctant to walk. Statistics reveal that the distance he is prepared to walk from his parking place to his shopping center is very short. As there are no adequate off-street parking facilities, the cities are littered with kerb-parked cars and parking meters rear themselves everywhere. Congestion has become the predominant factor in his environment, and statistics suggest that two cars per household system may soon make matters worse.In the meantime, insult is added to injury by “land value”. The value of land results from its use: its income and its value increase. “Putting land to its highest and best use” becomes the principal economic standard in urban growth. This speculative approach and the pressure of increasing population lead to the “vertical” growth of cities with the result that people are forced to adjust themselves to congestion in order to maintain these relatively artificial land values. Paradoxically the remedy for removing congestion is to create no re of it.Partial decentralization, or rather, pseudo-decentralization, in the form of large development units away from the traditional town centers, only shifts the disease round the anatomy of the town, if it is not combined with remodeling of the towns transportation system, it does not cure it. Here the engineering solutions are strongly affected by the necessity for complicated intersections, which in turn, are frustrated by the extravagant cost of land.It is within our power to build better cities and revive the civic pride of their citizens, but we shall have to stop operating on the fringe of the problem. We shall have to radically to replan them to achieve a rational densities of population we have to provide in them what can be called minimum “psychological elbow room”. One of the ingredients of this will be proper transportation plans. These will have to be an integral part of the overall planning process which in itself is a scientific process where facts are essential. We must collect, in an organized manner, all and complete information about the city or the town, if we want to plan effectively.The principal unit in this process is “IM”(one man). We must not forget that cities are built by people, and that their form and shape should be subject to the will of the people. Scientific methods of data collection and analysis will indicate trends, but they will not direct action. Scientific methods are only an instrument. The “man-educated” man, the human, will have to set the target, and using the results obtained by science and his own engineering skill, take upon himself the final shaping of his environment. He will have to use his high moral sense of responsibility to the community and to future generations. 11. The main concern of this passage is with_.A city culture Bland value in citiesC city congestionD decentralization12.It can be inferred from the first paragraph that people in old times_. A paid more attention to material benefits B had a stronger sense of beauty C were more desirous about the development of science and technology D enjoyed more freedom and democracy13.The highly-developed technology has made man_.A increasingly industriousB free from inconvenienceC excessively dependent on external aidsD able to save his physical strength14 The drastic increase of land value in the city_.A is the good result of economic development B offers more opportunities to land dealersC is annoyingly artificial and meaninglessD fortunately leads to the “vertical” growth of cities15. The expansion of big cities to the distant suburban areas may_.A solve the problem of city congestionB result in the remodeling of the towns transportation systemC bring the same congestion to the suburban areasD need less investment on land 16 the main purpose of the author is to_. .A point out a problem and criticize it B advocate that all cities need to be re-planned and remodeledC point out the significance of solving the problemD criticize a problem and try to find a solution to it 17 the author suggests that the remodeling of cities must_.A put priority to the benefit of the future generationsB be focused on people rather than on economy.C be economically profitable to land ownersD resort to scientific methods18 who will probably like to read articles of this kind/A businessmen B economists C urban people D rural peoplePassage 4Questions 19-25 are based on the following passage.（GRE阅读）The two claws of the mature American lobster are decidedly different from each other. The crusher claw is short and stout: the cutter claw is long and slender. Such bilateral asymmetry, in which the right side of the body is, in all other respects, a mirror image of the left side, is not unlike handedness in humans. But where the majority of humans are right-handed, in lobsters the crusher claw appears with equal probability on either the right or left side of the body.Bilateral asymmetry of the claws comes about gradually. In the juvenile fourth and fifth stages of development, the paired claws are symmetrical and cutter-like. Asymmetry begins to appear in the juvenile sixth stage of development, and the paired claws further diverge toward well-defined cutter and crusher claws during succeeding stages. An intriguing aspect of this development was discovered by VictorEmmel. He found that if one of the paired claws is removed during the fourth of fifth stage, the intact claw invariably becomes a crusher, while the regenerated claw becomes a cutter. Removal of a claw during a later juvenile stage or during adulthood, when asymmetry is present, does not alter the asymmetry, the intact and the regenerated claws retain their original structures.These observations indicate that the conditions tat trigger differentiation must operate in a random manner when the paired claws are intact but in a nonrandom manner when one of the claws is lost. One possible explanation is that differential use of the claws determine their asymmetry. Perhaps the claw that is used more becomes the crusher. This would explain why, when one of the claws is missing during the fourth or fifth stage, the intact claw always becomes a crusher. With two intact claws, initial use of one claw might prompt the animal to use it more than the other throughout the juvenile fourth and fifth stages, causing it to become a crusher.To test this hypothesis, researchers raised lobsters in the juvenile fourth and fifth stages of development in a laboratory environment in which the lobsters could manipulate oyster chips. (Not coincidentally, at this stage of development lobsters typically change from a habitat where they drift passively to the ocean floor where they have the opportunity to be more active by burrowing in the substratum.) Under these conditions, the lobsters developed asymmetric slaws, half with crusher claws on the left, and half with crusher claws on the right. In contrast, when juvenile lobsters were reared in a smooth tank without the oyster chips, the majority developed two cutter claws. This unusual configuration of symmetrical cutter claws did not change when the lobsters were subsequently placed in a manipulatable environment or when they lost and regenerated one or both claws.这篇文章开始提出了一个有趣的有待解释的现象，即“美洲龙虾的两螯大小不一样 ”。读者可以通过这点判断出全文为“解释针对问题”型文章。再往下看，文章的第二段的首句并没有进行转折，而是继续对这种奇怪现象的形成进行讲述，因为与第一段是顺承关系，所以第二段的首句即为该段的大意句。直到文章的第三段，作者才给出了一个对这一现象的解释，标志性的词语是One possible explanation is that, 暗示着着将是一个作者给予正评价的解释，所以这句话是全文的中心句。最后，在文章的最后一段，作者用了一个试验证实了上文的解释是有效的。作者并没有给出其他的解释针对这一现象，所以可以肯定的是，这篇文章是属于“一个解释针对一个问题”。19 the passage is primarily concerned with_.A drawing an analogy between asymmetry in lobsters and handedness in humans B developing a method for predicting whether crusher claws in lobsters will appear on the left or right side C explaining differences between lobsters crusher claws and cutter clawsD discussing a possible explanation for the bilateral asymmetry in lobsters 20 each of the following statements about the development of a lobsters crusher claw is supported by information in the passage except_.A It can be stopped on one side and begin on the other after the juvenile sixth stage.B It occurs gradually over a number of stages.C It is initially apparent in the juvenile sixth stage.D It can occur even when a prospective crusher claw is removed in the juvenile sixth stage.21 which of the following experimental results, if observed, would most clearly contradict the findings of Victor Emmel?A. A left cutter-like claw is removed in the fifth stage and a crusher claw develops on the right side.B. A left cutter-like claw is removed in the sixth stage and a crusher claw develops on the right side.C. A left cutter-like claws are removed in the fifth stage and a crusher claw develops on the lift side.D. Both cutter-like claws are removed in the fifth stage and a crusher claw develops on the left sid
