北京航空航天大学博士研究生入学考试试题一参考答案及详解

北京航空航天大学博士研究生入学考试试题一参考答案及详解

北京航空航天大学博士研究生入学考试英语模拟试题一PART 1 Listening Comprehension (20 points) (略)PART II Reading Comprehension(30 points)Directions:There are four passages in the part. Each passage is followed by some questions or unfinished statements. For each of them, there are 4 choices marked A, B, C and D. Read the passages carefully and decide on the best choice. Then mark the corresponding letter on the ANSWER SHEET with a single line through the center.Passage 1Unless we spend money to spot and prevent asteroids(小行星) now, one might crash into Earth and destroy life as we know it, say some scientists.Asteroids are bigger versions of the meteoroids(流星) that race across the night sky. Most orbit the sun far from Earth and don't threaten us. But there are also thousands whose orbits put them on a collision course with Earth.Buy $ 40 million worth of new telescopes right now. Then spend $ 10 million a year for the next 25 years to locate most of the space rocks. By the time we spot a fatal one, the scientists say, we'll have a way to change its course.Some scientists favor pushing asteroids off course with nuclear weapons. But the cost wouldn't be cheap.Is it worth it? Two things experts consider when judging any risk are: 1) How likely the event is; and 2) How bad the consequences if the event occurs. Experts think an asteroid big enough to destroy lots of life might strike Earth once every 400, 000 years. Sounds pretty rare-but if one did fall, it would be the end of the world. "If we don't take care of these big asteroids, they'll take care of us," says one scientist. "It's that simple."The cure, though, might be worse than the disease. Do we really want fleets of nuclear weapons sitting around on Earth? "The world has less to fear from doomsday (毁灭性的) rocks than from a great nuclear fleet set against them," said a New Y ork Times article.21. What does the passage say about asteroids and meteoroids?A. They are heavenly bodies different in composition.B. They are heavenly bodies similar in nature.C. There are more asteroids than meteoroids.D. Asteroids are more mysterious than meteoroids.22. What do scientists say about the collision of an asteroid with Earth?A. It is very unlikely but the danger exists.B. Such a collision might occur once every 25 years.C. Collisions of smaller asteroids with Earth occur more often than expected.D. It's still too early to say whether such a collision might occur.23. What do people think of the suggestion of using nuclear weapons to alter the course of asteroids?A. It sounds practical but it may not solve the problem.B. It may create more problems than it might solve.C. It is a waste of money because a collision of asteroids with Earth is very unlikely.D. Further research should be done before it is proved applicable.24. We can conclude from the passage that _.A. while pushing asteroids off course nuclear weapons would destroy the worldB. asteroids racing across the night sky are likely to hit Earth in the near futureC. the worry about asteroids can be left to future generations since it is unlikely to happen in our lifetimeD. workable solutions still have to be found to prevent a collision of asteroids with Earth.25. Which of the following best describes the author's tone in this pass age?A. Optimistic.B. Critical.C. Objective.D. Arbitrary.Passage 2Believe it or not,optical illusion (错觉) can cut highway crashes.Japan is a case in point. It has reduced automobile crashes on some roads by nearly 75 percent using a simple optical illusion. Bent stripes, called chevrons (人字形)painted on the roads make drivers think that they are driving faster than they really are, and thus drivers slow down.Now the American Association Foundation for Traffic Safety in Washington D. C. is planning to repeat Japan's success. Starting next year, the foundation will paint chevrons and other patterns of stripes on selected roads around the country to test how well the patterns reduce highway crashes.Excessive speed plays a major role in as much as one fifth of all fatal traffic accidents, according to the foundation. To help reduce those accidents, the foundation will conduct its tests in areas where speed-related hazards are the greatest-curves, exit slopes, traffic circles, and bridges. Some studies suggest that straight, horizontal bars painted across roads can initially cut the average speed of drivers in half. However, traffic often returns to full speed within months as drivers become used to seeing the painted bar.Chevrons, scientists say,not only give drivers the impress ion that they are driving faster than they really are but also make a lane appear to be narrower. The result is a longer lasting reduction in highway speed and the number of traffic accidents.26. The passage mainly discusses .A. a new way of highway speed controlB. a new pattern for painting highwaysC. a new approach to training driversD. a new type of optical illusion27. On roads painted with chevrons drivers tend to feel that .A. they should avoid speed-related hazardsB. they are driving in the wrong laneC. they should slow down their speedD. they are approaching the speed limit28. The advantage of chevrons over straight, horizontal bars is that the former .A. can keep drivers awakeB. can cut road accidents in halfC. will have a longer effect on driversD. will look more attractive29. The American Association Foundation for Traffic Safety plans to .A. try out the Japanese method in certain areasB. change the road signs across the countryC. replace straight horizontal bars with chevronsD. repeat the Japanese road patterns30. What does the author say about straight, horizontal bars painted across roads?A. They are falling out of use in the United States.B. They tend to be ignored by drivers in a short period of time.C. They are applicable only on broad roads.D. They cannot be applied successfully to traffic circles.Passage 3There are a number of formats for reporting research, such as articles to appear in journals, reports addressed to funding agencies, theses or dissertations as part of the requirements for university degrees, and papers to be presented at conferences. These formats differ from one another mostly in their purposes and the audiences whom they address. We will now briefly describe them.The journal article is a way of reporting research for professional journals or edited collections. The research is reporting in a brief, yet informative way, focusing mostly on the main features of the research such as the purpose, review of the literature ( often referred to as "background" ), procedures used for carrying out the research accompanied by tables, charts, and graphs, and interpretations of the results ( often referred to as discussion).The content and emphasis of the journal article will vary according to the intended readers (research or practitioners) and it is important for the researcher to be aware of the background and interest of the readers of the journal. Articles intended to be read by practitioners will emphasize the practical implications and recommendations of the research, while articles intended to be read by researchers will describe in detail the method used to collect data, the construction of data collection procedures, and the techniques used for analyzing the data. It is important for the novice researcher to be aware of the fact that articles submitted to journals go through a process of evaluation by experts who make a judgment and recommend whether they should be published or not.The thesis or dissertation is a format for reporting research which graduate students write as part of fulfilling the requirements for an advanced academic degree. The student is expected to describe in great detail all the phases of the research so it can be examined and evaluated carefully by the reader. Thus the thesis or dissertation includes the purpose and significance of the study, the rationale, a thorough review of the literature, detailed information as to the research tools and the procedures involved in their development, a description of data analysis and the results, and an interpretation of the results in the form of conclusions, implications, and recommendation. Thisdetailed description of the process of the research is needed to provide the professors with an indication of the student's ability to carry out research.The conference paper is a way of reporting research at conferences, seminars and colloquia. At such meetings research papers are usually presented orally. They are similar to the research 'article since research is reported in a concise, yet informative way, focusing on the most essential elements of the research. Handouts and transparencies can also accompany the presentations. As with the research article, here too, the content and emphasis of the oral report will depend to a large extent on the type of audience present at the meeting .and whether they are researchers or practitioners.31. The best title for this passage could beA. Types of Research ReportsB. Types of Journal ArticlesC. Writing of research ReportsD. Writing of Different Artic les32. The common aspect for the journal articles, theses and conference papers lies in thatA. they are all for the practitionersB. they are all to be read by researchersC. they are all for being publishedD. they are all forms of reporting research33. We can distinguish those research reports from each other mainly throughA. their writing style and lengthB. their aims and possible audiencesC. their presented places and timeD. their content and purposes34. Which of the following statements is NOT mentioned in this passage?A. Both journal articles and conference papers are reported in a brief and informative way.B. All the theses or dissertations and conference papers are reported in spoken languages.C. Both the journal articles and conference papers are influenced greatly by the intended receivers.D. The various formats of research reports may be presented in different ways.35. How can a professor evaluate a student's capability of implementing the research?A. By concentrating on the main factors like the purpose, background, procedures and discussion.B. By emphasizing the practical implications and recommendations of the research.C. By focusing on the detailed description of the process of the research such as the tools, procedures, the process of data analysis, the results, conclusions, etc.D. By noticing the detailed method used to collect the data, the construction of the data collection procedures, the techniques for analyzing the date and results, etc.Passage 4In recent years, many Americans of both sexes and various ages have become interested in improving their bodies. They have become devoted to physical fitness. The need to exercise has almost become compulsive with many persons who have a strong desire to be more physically fit.By nature, Americans are enthusiastic and energetic about their hobbies and pastimes. They apply this enthusiasm, and energy to jogging/running. As a result, there are running clubs to join andmany books and magazines to read about running.The desire to be physically fit is explained by a "passion" for good health. The high rate of heart attacks in the 1960s caused an increase on the part of the public in improving the human body.Middle-aged men especially suffer from heart attacks. Thus, they are one group strongly interested in more physical exercise. In fact, many doctors encourage their patients to become more physically active, especially those who have sedentary jobs. It is interesting to note that the rate of heart attacks began to decrease in the 1970s and it is still decreasing.Physical fitness currently enjoys a favored role in the United States. It is a new "love" that many Americans have cherished. Will it last long? Only time will tell or until another "new passion" comes along.36. In recent years, many Americans have become interested in improving their bodies becauseA. they are enthusiastic about their hobbies and pastimesB. they have a strong desire to be more physically fitC. there are many running clubs to joinD. there are many books and magazines to read about running37.

Write your translation on the ANSWER SHEET (2).The fact known to us is that war, different from what many people believe it to be, is not completely an outcome of" humanity". Otherwise,war and violence among people would exist in all the human history or ahnost all societies. However, this is not the truth. Archaeologists' investigation results seem to suggest that men lived quite a peaceful life long ago. For example, among ancient French cave drawings which were earlier than 10, 000 B. C., there were no pictures describing people fighting with each other. This indicates that, in that early period of mankind, fight among people was comparatively rare.In a certain way, this discovery is not surprising at all:in the world of animals, it's rare for one to prey on another of its own species. They do kill other kinds of animals, but not their own. Like most animals, the proportion of inner violence among early human beings was relatively small. Therefore, war is not the inherent outcome of humanity but that of certain social and cultural conditions.PART VI Writing(15 points)Directions:A.

2023年北京航空航天大学博士研究生入学考试英语试题

2023年北京航空航天大学博士研究生入学考试英语试题

北京航空航天大学2023年博士研究生入学考试英语试题Part ⅠListening Comprehension (20 points)(略)Part ⅡReading Comprehension (30 points)Directions: There are four passages in the part. Each passage is followed by some questions or unfinished statements. For each of them, there are 4 choices marked A, B, C and D.Read the passages carefully and decide on the best choice. Then mark the corresponding letter on the ANSWER SHEET with a single line through the center.Passage 1Scientists now tend to agree that the noise level for potential hearing loss begins at about 70decibels. Some of them are very concerned because normal daily life often exposes people to noise levels of about 70 decibels even inside their homes. Cities have always been noisy, but noise is now spreading to areas that were quiet just a few years ago.Clearly, something must be done or noise will seriously and permanently maim the population. Fortunately, the knowledge and methods to control noise already exist. As a matter of fact, this is one instance where the knowledge of control methods exceeds the knowledge about the effects on human life and on the environment.There are two common means for control. The first is reducing noise at its source, and the second is changing the sound path by distance or by shielding.The second approach is being used more often today as people become more aware of the danger of noise. New building codes require better sound insulation in homes and apartments. More and more towns are passing zoning ordinances that try to segregate noisy factories or airports from residential areas. Sound-absorbent materials and construction designed to block sound paths are slowly coming into use in offices and homes. New highways are being built to redirect traffic noise up and away from nearby areas. Aircraft are increasingly being required touse reduced power flights around airports.There are many examples of available noise control methods that are not being used. More flexible building codes would permit the use of quieter kinds of plumbing pipes. Sound-absorbing materials can reduce the noise of motors and engines. Power generators can be quieted with baffles, exhaust silencers, and sound absorbers. Truck tires can be made with quieter treads. In many cases, the cost of building quieter machines is the same or only slightly higher than that of the current noisy ones. Even though the new equipment may cost more initially, it can prove more profitable in the long run. The new jumbo jets, for example, are quieter than the older ones, yet they are more powerful and carry twice as many passengers.All of these methods are only partial measures as noisy levels continue to rise. Most specialists in the field agree that much of the solution must come from eliminating some of the noise at its source, therefore saving through prevention the large costs of hearing loss.21.The noise level for possible hearing loss begins at about ______.A.30 decibels B.75 decibels C.100 decibels D.none of the above 22.Jet pilots are being advised to land ______.A.on longer runways B.from nearby areas C.after dark D.with reduced power 23.How many practical means for controlling noise does the author present?A.One. B.Two. C.Three. D.Four.24.The reader can assume that airport of the future will ______.A.have runways in a north-south patternB.be located in unpopulated areasC.be required to warn passengers of high noise levelsD.in nearby areas25.Jumbo jets are mentioned as examples of ______.A.efficient transportation with low levels of noiseB.vehicles that cause serious air pollutionC.scientific advances that do more harm than goodD.quieter and older vehiclePassage 2Every time a person eats something he makes a nutritional decision. He accepts or rejects the food available to him at home for meals or snacks. Or he selects food for himself at many places in the community, such as supermarkets, drive-ins, restaurants, and food counters in drugstores. These selections make a difference in how an individual looks, how he feels, and how well he can work and play.When a good assortment of food in appropriate amounts is selected and eaten, the consequences are more likely to be a desirable level of health and enough energy to allow one to be as active as one needs and wants to be. When choices are less than desirable, the consequences are likely to be poor health or limited energy or both.Studies of diets of individuals in the United States show that food selection is a highly individual matter, even among young children. Furthermore, far too many individuals of all ages are making poor choices day after day and are either now living with the consequences or will be in the future.Nutritionists and workers in allied professions have been concerned about helping people learn to select and enjoy a wide variety of food combinations that can add up to a good diet.Most people believe that they are well fed—that the choices they make are good ones. After all, they are not really sick, neither are they hungry. However, their nutrition is usually poor in one respect or another. Milk and milk products, such as cheeses, ice cream or milk, buttermilk, and yogurt, are often slighted. Then people may skip many fruits and vegetables, particularly those that are good sources of vitamins A and C.These include dark green leafy vegetables; deep yellow vegetables; and citrus fruits and vegetables, such as cabbage, tomatoes, and green peppers.Every American has the right to choose to be uniformed about nutrition as well as to be informed.If a person believes that she is well fed, attitudes, habits, and information cannot be forced upon her.There are life situations, however, that tend to cause all individual to want to know how to make the best choices. For example, a young couple is starting a family and must prepare food for young children.26.Food preference in America is ______.A.culturally oriented B.inherited C.individualistic D.according to ages 27.Good amounts of vitamin A can be found in ______.A.celery B.banana C.milk D.cabbage 28.According to the author, nutritionists are concerned with ______.A.improving the vitamin content of processed foodsB.restricting the manufacture of high cholesterol foodsC.informing the public about wholesome foodsD.helping people enjoying uninformed about nutrition29.Some people judge their nutrition by the ______.A.status of their health B.grocery stores where they shopC.amount of protein in their diets D.food they took30.The author advocatesA.requiring high school students to take courses on nutritionB.making information on nutrition available to the publicC.forcing food manufacturers to list ingredients on packagesD.people has the right to choose foodPassage 3Almost since the beginning of mankind, governments have been recording the numbers of their populace. The first known census report took place in 3800 B. C. in Babylonia for the purpose of deciding who should pay taxes. As time went by, governments found other, more creative usesfor knowing their numbers. Egyptian King Ramses Ⅱused the census not only to determine who should pay taxes, but also to figure out how to divide land for farming and to decide who could provide manpower for various government projects. These new ideas came about in the mid-1200s-B. C.William the Conqueror brought the concept of census taking to England in 1085. All landowners were required to name their holdings for the purpose of taxation. By the fifteenth century, Tudor kings found a new twist to the Egyptians' use of the census. They too used the population count as a means of getting ready manpower for important government project' namely, replenishing troops in the ongoing battles in western Europe.A rebellious tide swept over England, however, in the mid-1700s. A bill to authorize a regular census was defeated in Parliament on the grounds that it would give valuable information to England's enemies. But the tide of rebellion soon turned, and in 1800 England established its first regular census.Meanwhile the United States had already had an ongoing census for ten years. It was authorized in the Constitution for the purpose of deciding how many members of Congress would be needed for a fair representation of the American people. The constitutional article also established that the census would be taken in 1790 and every ten years thereafter. And so it has. Since its beginning, the American census has gone through many changes. Today the census provides more than a count of the people who live here. It takes polls on transportation, economic planning, and agriculture. The census also provides data for most government agency statistics, such as the unemployment rate.Counting costs have risen since 1790.The government spent about a penny per person to count post-Revolutionary Americans. Today the census costs $ 250 million—more than a dollar per person. That's a long way since 3800 B.C..31.The first known census report took place in Babylonia in ______.A.1085 B.1200 B. C.3800 B.C. D.179032.The first census was created for the sole purpose of ______.A.counting available troops B.dividing farmlandC.providing manpower D.taxing the populace33.The American census today costs the government approximately ______.A.$0.01/person B.$0.10/person C.$1.00/person D.$10.00/person 34.Parliament defeated a bill authorizing a regular census because it ______.A.might give valuable news to EnglandB.would give England's enemies cause for rebellionC.would be too expensiveD.might disclose information to England's enemies35.The author implies the American census is ______.A.relatively inexpensive to conductB.important to various government branchesC.an exact count of the citizenryD.fairly expensive before 1790Passage 4It didn't happen overnight. The problem of polluted air has been festering for centuries. Suddenly the problem of air pollution is becoming critical and is erupting right before our eyes. Not only do our eyes burn as they focus through murky air, but when the air clears, we see trees and vegetation dying. We must realize that this destruction can no longer be pinned to some mysterious cause. The one major culprit is air pollution.Today's air pollution is an unfortunate by-product of the growth of civilization. Civilized mall desires goods that require heavy industrialization and mass production. Machines and factories sometimes pollute and taint the air with substances that are dangerous to man and the environment. These substances include radioactive dust, salt spray, herbicide and pesticide aerosols, liquid droplets of acidic matter, gases, and sometimes soil particles. These materials canact alone to irritate objects and forms of life. More dangerously, they join together to act upon the environment. Only lately have we begun recognizing some of their dangerous consequences. Scientists have not yet been able to obtain a complete report on the effects of air pollution on trees. They do know, however, that sulfur dioxide, fluorides, and ozone destroy trees and that individual trees respond differently to the numerous particulate and gaseous pollutants. Sometimes trees growing in a single area under attack by pollutants will show symptoms of injury or will die while their neighbors remain healthy. Scientists believe this difference in response depends on the kind of tree and its genetic makeup. Other factors, such as the tree's stage of growth and nearness to the pollution source, the amount of pollutant, and the length of the pollution attack also play a part. In short, whether or not a tree dies as a result of air pollution depends on a combination of host and environmental factors.For the most part, air pollutants injure trees. To conifers, which have year-round needles, air pollution causes early balding. In this event, trees cannot maintain normal food production levels. Undernourished and weakened, they are open to attack by a host of insects, diseases, and other environmental stresses. Death often follows.Air pollution may also cause hardwoods to lose their leaves. Because their leaves are borne only for a portion of the year and are replaced the following year, air pollution injury to hardwoods may not be so severe.36.The author attributes today's air pollution to ______.A.the growth of civilization B.man's carelessnessC.environmental imbalance D.some mysterious cause37.The resistance of some trees to disease can be traced to ______.A.protective foliage B.thick bark C.genetic makeup D.tainted air38.Air pollution causes the most damage to ______.A.hardwoods B.conifers C.fruit trees D.fluorides39.The author implies that the greatest source of pollution is ______.A.heavy industry B.chemical processing plantsC.urban expansion D.salt spray40.We can conclude that ______.A.air pollution is easier to control than water pollutionB.the problem of polluted air is a problem overnightC.the impact of air pollution has been known for centuriesD.research on the efforts of air pollution is incompletePart ⅢVocabulary (10 points)Directions: In this part, there are 20 sentences with four choices below each sentence.

Then mark the corresponding letter on the Answer Sheet with a single line through the center.It is not long since conditions in the mines were worse than they are now. There are still 61 a few very old women who in their youth have worked 62, with harness round their waists, and a chain 63 passed between their legs, crawling on all 64 and dragging tugs of coal. They used to go on 65 this even when they were pregnant.And 66 now, if coal could not be produced without pregnant women dragging it 67 and fro, I fancy we should let them do it 68 than deprive ourselves of coal. But most of the time, of course, we should 69 to forget that they were doing it. It is the 70 with all types of manual work; it keeps us alive, and we are oblivious of its existence. More than anything 71 perhaps, the miner can stand as the type of manual worker, not only because it is so vitally necessary and 72 so 73 , that we are capable 74 forgetting it as we forget the blood in our veins. In 75 way it is even humiliating to watch coal-miners working. It raises in you a momentary doubt 76 your own status as an “intellectual” and a superior person generally.

Write your translation on the ANSWER SHEET(2).Two teams of astronomers using the Hubble Space Telescope have overturned several decades of conjecture and theory by ruling out the possibility that small, dim stars make up most of the mass in the universe.Until now, small stars known as faint red dwarfs were considered ideal candidates for the so-called “dark matter” that is believed to account for more than 90 percent of the mass of the universe.All visible celestial objects, such as planets, stars and galaxies, are believed to account for only 10 percent of the mass of the universe. The rest of the “missing mass” is presumably invisible because it does not emit or reflect light, or the light is too feeble to be detected. But dark matter can be indirectly detected due to its gravitational influence on other visible objects.According to Bacall, professor of natural science at the Institute of Advanced Study in Princeton, New Jersey and leader of one of the teams, the nature of dark matter, and its abundance, are among the most important questions in modern cosmology today.The ultimate fate of the universe will be determined by the amount of dark matter present. If there is not enough dark matter to bind the universe together gravitationally, it could continue expanding forever. If there is enough mass to hold the universe together gravitationally, the universe may slow down its expansion, come to a halt and begin to contract and eventually collapse.Part ⅥWriting (15 points)Directions: Write a composition of no less than 200 words on the following topic on the Answer Sheet(2): Opportunity and Success.。

北京航空航天大学考博英语真题2016年

北京航空航天大学考博英语真题2016年(总分:100.00,做题时间:180分钟)Ⅰ Reading Comprehension(总题数:0,分数:0.00)Test One(总题数:5,分数:0.00). Which is safer—staying home, traveling to work on public transport, or working in the office? Surprisingly, each of these carries the same risk, which is very low. However, what about flying compared to working in the chemical industry? Unfortunately, the former is 65 times riskier than the latter! In fact, the accident rate of workers in the chemical industry is less than that of almost any of human activity, and almost as safe as staying at home.The trouble with the chemical industry is that when things go wrong they often cause death to those living nearby. It is this that makes chemical accidents so newsworthy. Fortunately, they are extremely rare. The most famous ones happened at Texas City (1947), Flixborough (1974), Seveso (1976), Pemex (1984) and Bhopal (1984).Some of these are always in the minds of the people even though the loss of life was small. No one died at Seveso, and only 28 workers at Flixborough. The worst accident of all was Bhopal, where up to 3,000 were killed. The Texas City explosion of fertilizer killed 552. The Pemex fire at a storage plant for natural gas in the suburbs of Mexico City took 542 lives, just a month before the unfortunate event at Bhopal.Some experts have discussed these accidents and used each accident to illustrate a particular danger. Thus the Texas City explosion was caused by tons of ammonium nitrate (硝酸铵), which is safe unless stored in great quantity. The Flixborough fireball was the fault of management, which took risks to keep production going during essential repairs. The Seveso accident shows what happens if the local authorities lack knowledge of the danger on their doorstep. When the poisonous gas drifted over the town, local leaders were incapable of taking effective action. The Pemex fire was made worse by an overloaded site in all overcrowded suburb. The fire set off a chain reaction of exploding storage tanks. Yet, by a miracle, the two largest tanks did not explode. Had they caught fire, then 3,000 strong rescue teams and fire fighters would all have died.1. Which of the following statements is true? ______(分数:7.50)A.Working at the office is safer than staying at home.B.Traveling to work on public transport is safer than working at the office.C.Staying at home is safer than working in the chemical industry.D.Working in the chemical industry is safer than traveling by air.Test Two(总题数:5,分数:0.00). Of the thousands of different kinds of animals that exist in the world, man has learned to make friends with an enormous number. Some are pets and offer him companionship; some give him protection, and some do hard work which man cannot do for himself. Dogs, which serve man in all three capacities, are found in various breeds in all countries of the world. The Husky can live in the cold polar regions, and the Saluki is at home in the hottest parts of Central Africa. The inhabitants of certain countries are dependent for their very lives on the camel. In the West Indies the little donkey, strong and sure-footed, carrying heavy loads even in mountainous places, is a familiar sight.Trained and tamed for many generations, domestic animals are not accustomed to roaming in search of food and shelter. They look to their masters to provide for their needs, and as long as these are supplied, they are content to do what their masters require.All domestic animals need proper food. It must be suitable for them, sufficient in quantity, fresh and clean. Some people feed a pet dog or cat on odds and ends of table scraps, and then wonder why the animal seems listless and dull. The quantity of food depends on the size of the animal and the amount of exercise it takes. Overfeeding is as bad as underfeeding. Containers for food and water must be washed regularly if the animal is to maintain good health.Even well-cared-for animals may sometimes fall ill. If this happens, the wise master seeks the best advice he can get. All sorts of medicines and treatments are available for sick animals, and in some countries organizations exist to provide them free or at a cheap price. Useful, friendly, hardworking animals deserve to have some time, money and attention spent on their health.1. What main idea does the author want to convey in the first paragraph?(分数:7.50)A.There exists thousands of species of animals in the world.B.Man came to establish a close relationship with a number of animals.C.In some regions a donkey seems to be a very useful beast.D.An animal will be useless unless domesticated.Test Three(总题数:5,分数:0.00). Trees should only be pruned when there is a good and clear reason for doing so and, fortunately, the number of such reasons is small. Pruning involves the cutting away of overgrown and unwanted branches, and the inexperienced gardener can be encouraged by the thought that more damage results from doing it unnecessarily than from leaving the tree to grow in its own way.First, pruning may be done to make sure that trees have a desired shape or size. The object may be to get a tree of the right height, and at the same time to help the growth of small side branches which will thicken its appearance or give it a special shape. Secondly, pruning may be done to make the tree healthier. You may cut diseased or dead wood, or branches that are rubbing against each other and thus cause wounds. The health of a tree may be encouraged by removing branches that are blocking up the center and so preventing the free movement of air.One result of pruning is that an open wound is left on the tree and this provides an easy entry for disease, but it is a wound that will heal. Often there is a race between the healing and the disease as to whether the tree will live or die, so that there is a period when the tree is at risk. It should be the aim of every gardener to reduce that risk of death as far as possible. It is essential to make the area, which has been pruned, smooth and clean, for healing will be slowed down by roughness. You should allow the cut surface to dry for a few hours and then paint it with one of the substances available from garden shops produced especially for this purpose. Pruning is usually without interference from the leaves and also it is very unlikely that the cuts you make will bleed. If this does happen, it is, of course, impossible to paint them properly.1. Pruning should be done to ______.(分数:7.50)A.make the tree grow tallerB.improve the shape of the treeC.get rid of the small branchesD.make the small branches thickerTest Four(总题数:5,分数:0.00). The human criterion for perfect vision is 20/20 for reading the standard lines on a Snellen eye chart without a hitch. The score is determined by how well you read lines of letters of different sizes from 20 feet away. But being able to read the bottom line on the eye chart does not approximate perfection as far as other species are concerned. Most birds would consider us very visually handicapped. The hawk, for instance, has such sharp eyes that it can spot a dime on the sidewalk while perching on top of the Empire State Building. It can make fine visual distinctions because it is blessed with one million cones per square millimeter in its retina (视网膜). And in water, humans are farsighted, while the kingfisher, swooping down to spear fish, can see well in both the air and water because it is endowed with two foveae (凹窝) areas of the eye, consisting mostly of cones that provide visual distinctions. One fovea permits the bird, while in the air, to scan the water below with one eye at a time. This is called monocular vision. Once it hits the water, the other fovea joins in, allowing the kingfisher to focus both eyes, like binoculars, on its prey at the same time. A frog's vision is distinguished by its ability to perceive things as a constant motion picture. Known as "bug detectors", a highly developed set of cells in a frog's eyes responds mainly to moving objects. So, it is said that a frog sitting in a field of dead bugs wouldn't see them as food and would starve.The bee has a "compound" eye, which is used for navigation. It has 15,000 facets that divide what it sees into a pattern of dots or mosaic. With this kind of vision, the bee sees the sun only as a single dot, a constant point of reference. Thus, the eye is a superb navigational instrument that constantly measures the angle of its line of flight in relation to the sun. A bee's eye also gauges flight speed. And if that is not enough to leave our 20/20 "perfect vision" paling into insignificance, the bee is capable of seeing something we can't—ultraviolet light. Thus, what humans consider to be "perfect vision" is in fact rather limited when we look at other species. However, there is still much to be said for the human eye. Of all the mammals, only humans and some primates can enjoy the pleasures of color vision.1. The Snellen eye chart measures one's eyesight by ______.(分数:7.50)A.the number of lines he readsB.the distance he stands away from the chartC.the speed at which he recognizes the lettersD.several integrative factorsⅡ Vocabulary(总题数:20,分数:0.00)1.

The front matter of a book consists of the title, subtitle, table of contents, and preface. But the 1 of readers who pay no attention to the signals is larger than you might expect, unless you happen to be one of those who are 2 to admit it.

Financially, sure, but also in ways that are impossible to measure.1 From the earliest days of our country, we have seen education as the foundation for democracy and citizenship, for social mobility and national prosperity. Higher education opens minds and opens doors. Yet high school students and families are increasingly questioning its value. Is investing in a college or university education still worth it?The short answer is "yes". There is no doubt that college pays off financially. A wide range of statistics shows the economic advantage of a four-year college education. Over a lifetime, students who graduate from college can expect to make about 60% more than those who do not, well over a million dollars more than they would otherwise. Completing college makes an even greater difference to the earning power of young women. A 25-to-34-year-old female with a bachelor's degree can expect to make 70% more than if she had only completed her high school diploma. College graduates also tend to lead more active lives. They vote more often, volunteer more often and are more likely to own a home. They are healthier and less likely to smoke by a margin of 17 percentage points. They and their children are less likely to be obese, and their children are more likely to go to college. 2 Education encourages people to engage as citizens and live healthier and longer lives—powerful reasons for earning a college degree.But what about the benefits of college that are more difficult to measure? They are equally significant and add up to a lot of value over the course of a lifetime.College teaches students the virtue of slowing down. 3 No one denies the value of speed, connectivity and the virtual world in an economy that thrives on all three. But "thinking" is a word that is too often forgotten, trammeled in our rush to communicate faster and left behind as our brains struggle to keep up with our devices. College teaches students to slow down, to convert information to insight and knowing or understanding. 4 It nurtures critical engagement, enlightened skepticism, and an endless desire to self-educate, preparing students for a lifetime of considering information and growing in knowledge and in wisdom.In these ways and in so many others, college helps students see themselves differently, giving them the room and the license to imagine new possibilities. Yes, it opens opportunities reflected in earning and employment statistics. But, perhaps even more valuable, it opens minds and worlds in ways that defy measurement. I often ask students as they are approaching graduation how they are different from when they arrived at college. They say they know more. Sometimes, they say they found a passion they had never imagined—a field, a profession to which they intend to devote their lives. But what is more important, they often tell me, is that they have a new way of approaching the world, through the power of learning, analyzing, changing to adapt to what they have come to understand. 5 The value of higher education is embodied by people who dream bigger and achieve more, who create their own futures and shape their own destinies.(分数:20.00)1.

For each of them, there are 4 choices marked A, B, C, D. Read the passages carefully and decide on the best choice. Then mark the corresponding letter on ANSWER SHEET 1.Passage 1There has been a lot of hand-writing over the death of Elizabeth Steinberg. Withoutblaming anyone in particular, neighbors, friends, social workers, the police and newspapereditors have struggled to define the community’s responsibility to Elizabeth and to otherbattered children. As the collective soul-searching continues, there is a pervading sense that thesystem failed her.The fact is, in New York State the system couldn’t have saved her. It is almost impossible to protect a child from violent parents, especially if they are white, middle-class, well-educated and represented by counsel.Why does the state permit violence against children? There are a number of reasons. First, parental privilege is a rationalization. In the past, the law was giving its approval to the biblical injunction against sparing the rod.Second, while everyone agrees that the state must act to remove children from their homes when there is danger of serious physical or emotional harm, many child advocates believe that state intervention in the absence of serious injury is more harmful than helpful.Third, courts and legislatures tread carefully when their actions intrude or threaten to intrude on a relationship protected by the Constitution. In 1923, the Supreme Court recognized the “liberty of parent and guardian to direct the upbringing and education of children under their control.” More recently, in 1977, it upheld the teacher’s privilege to use corporal punishment against schoolchildren. Read together, these decisions give the constitutional imprimatur to parental use of physical force.Under the best conditions, small children depend utterly on their parents for survival. Under the worst, their dependency dooms them. While it is questionable whether anyone or anything could have saved Elizabeth Steinberg, it is plain that the law provided no protection.To the contrary, by justifying the use of physical force against children as an acceptable method of education and control, the law lent a measure of plausibility and legitimacy to her parents’ conduct.More than 80 years ago, in the teeth of parental resistance and Supreme Court doctrine, the New York State Legislature acted to eliminate child labor law. Now, the state must act to eliminate child abuse by banning corporal punishment. To break the vicious cycle of violence, nothing less will answer. If there isa lesson to be drawn from the death of Elizabeth Steinberg, it is this: Spare the rod and spare the child.21. The New York State law seems to provide least protection of a child from violent parentsof .A. a family on welfareB. a poor uneducated familyC. an educated black familyD. a middle-class white family22. “Sparing the rod” (黑体部分)means .A.childrenspoilingB. punishing childrenC. not caring about childrenD. not beating children23. Corporal punishment against schoolchildren is .A. taken as illegal in the New York StateB. considered being in the teacher’s provinceC. officially approved by lawD. disapproved by school teachers24. From the article we can infer that Elizabeth Steinberg is probably the victim of .A. teachers’ corporal punishmentB. misjudgment of the courtC. parents’ ill-treatmentviolencestreetD.25. The writer of this article thinks that banning corporal punishment will in the long run .A. prevent violence of adultsB. save more childrenC. protect children from ill-treatmentD. better the systemPassage 2For laymen ethnology is the most interesting of the biological sciences for the very reason that it concerns animals in their normal activities and therefore, if we wish, we can assess the possible danger and advantages in our own behavioral roots. Ethnology also is interesting methodologically because it combines in new ways very scrupulous field observations with experimentation in laboratories.The field workers have had some handicaps in winning respect for themselves. For a long time they were considered as little better than amateur animal-watchers—certainly not scientists, since their facts were not gained by experimental procedures: they could not conform to the hard-and-fast rule that a problem set up and solved by one scientist must be tested by other scientists, under identical conditions and reaching identical results. Of course many situations in the lives of animals simply cannot be rehearsed and controlled in this way. The fall flocking of wild free birds can’t be, or the roving animals over long distances, or even details of spontaneous family relationships. Since these never can be reproduced in a laboratory, they are then not worth knowing about?The ethnologists who choose field work have got themselves out of this impasse by greatly refining the techniques of observing. At the start of a project all the animals to be studied are live-trapped, marked individually, and released. Motion pictures, often in color, provide permanent records of their subsequent activities. Recording of the animals’ voices by electrical sound equipment is considered essential, and the most meticulous notes are kept of all that occurs. With this material other biologists, far from the scene, later can verify the reports. Moreover, two field observers often go out together, checking each other’s observations right there in the field.Ethnology, the word, is derived from the Greek ethos, meaning the characteristic traits or featureswhich distinguish a group-any particular group of people or, in biology, a group of animals such as a species. Ethnologists have the intention of studying “the whole sequence of acts which constitute an animal’s behavior.” In abridged dictionaries, ethnology is sometimes defined simply as “the objective study of animal behavior,” and ethnologists do emphasize their wish to eliminate myths.26. In the first sentence, the word “laymen” means .A. people who stand asideB. people who are not trained as biologistsC. people who are amateur biologistsD. people who love animals27. According to the passage, ethnology is .A. a new branch of biologyB. an old Greek sciencescienceforamateurspseudo-science D.aC.a28.“The field workers have handicaps in winning respect for themselves.” This sentence means .A. ethnologists when working in the field are handicappedB. ethnologists have problems in winning recognition as scientistsC. ethnologists are looked down upon when they work in the fieldD. ethnologists meet with lots of difficulties when doing field work29. According to the explanation of the scientific rule of experiment in the passage, “hand-and-fast” means experiment procedures .A. are difficult and quick to followB. must be carried out in a strict and quick wayC. must be followed strictly to avoid false and loose resultsD. hard and unreasonable for scientist to observe30. The meaning of the underlined words in “the details of spontaneous family relationships” can be expressed as .A. natural family relationshipsoccurringfamily relationshipsquicklyB.C. animals acting like a natural familyD. animal family behavior that cannot be preplanned or controlledPassage 3Since the dawn of human ingenuity, people have devised ever more cunning tools to cope with work that is dangerous, boring, burdensome, or just plain nasty. That compulsion has resulted in robotics- the science of conferring various human capabilities on machines. And if scientists have yet to create the mechanical version of science fiction, they have begun to come close.As a result, the modern world is increasingly populated by intelligent gizmos whose presence we barely notice but whose universal existence has removed much human labor. Our factories hum to the rhythm of robot assembly arms. Our banking is done at automated teller terminals that thank us with mechanical politeness for the transaction. Our subway trains are controlled by tireless robot-drivers. And thanks to the continual miniaturization of electronics and micro-mechanics, there are already robot systems that can perform some kinds of brain and bone surgery with sub-millimeter accuracy—far greater precision than highly skilled physicians can achieve with their hands alone.But if robots are to reach the next stage of laborsaving utility, they will have to operate with less human supervision and be able to make at least a few decisions for themselves—goals that pose a real challenge. ”While we know how to tell a robot to handle a specific error,” says Dave Lavery, manager of a robotics program at NASA,“We can’t yet give a robot enough ‘common sense’ to reliably interact with adynamic world.”Indeed the quest for true artificial intelligence has produced very mixed results. Despite a spell of initial optimism in the 1960s and 1970s when it appeared that transistor circuits and microprocessors might be able to copy the action of human brain by the year 2010, researchers lately have begun to extend that forecast by decades if not centuries.What they found, in attempting to model thought, is that the human brain’s roughly one hundred billion nerve cells are much more talented-and human perception far more complicated—than previously imaged. They have built robots that can recognize the error of a machine panel by a fraction of a millimeter in a controlled factory environment. But the human mind can glimpse a rapidly changing scene and immediately disregard the 98 percent that is irrelevant, instantaneously focusing on the monkey ate the side of a forest road or the single suspicious face in big crowd. The most advanced computer systems on Earth can’t approach that kind of ability, and neuroscientists still don’t know quite how we do it.31. Human ingenuity was initially demonstrated in .A. the use of machines to produce science fictionB. the wide use of machines in manufacturing industryC. the invention of tools for difficult and dangerous workD. the elite’s cunning tackling of dangerous and boring work32. The word “gizmos” (line 1, paragraph 2) most probably means .programsA.expertsB.devicesC.creaturesD.33. According to the text, what is beyond man’s ability now is to design a robot that can .A. fulfill delicate tasks like performing brain surgeryB. interact with human beings verballyC. have a little common senseD. respond independently to a changing world34. Besides reducing human labor, robots can also .A. make a few decisions for themselvesB. deal with some errors with human interventionC. improve factory environmentsD. cultivate human creativity35. The author uses the example of a monkey to argue that robots are .A. expected to copy human brain in internal structureB. able to perceive abnormalities immediatelyC. far less able than human brain in focusing on relevant informationD. best used in a controlled environmentPassage 4When it comes to the slowing economy, Ellen Spero isn’t biting her nails just yet. But the 47-year-old manicurist isn’t cutting, filling or polishing as many nails as she’d like to either. Most of her clients spend $12 to $50 weekly, but last month two longtime customers suddenly stopped showing up. Spero blames the softening economy. “I’m a good economic indicator,” she says. “I provide a service that people can do without when they’re concerned about saving some dollars.” So Spero is downscaling, shopping at middle-brow Dillard’s department store near her suburban Cleveland home, instead of Neiman Marcus. “Idon’t know if other clients are going to abandon me, too” she says.Even before Alan Greenspan’s admission that America’s red-hot economy is cooling, lots of working folks had already seen signs of the slowdown themselves. From car dealerships to Gap outlets, sales have been lagging for months as shoppers temper their spending. For retailers, who last year took in 24 percent of their revenue between Thanksgiving and Christmas, the cautious approach is coming at a crucial time. Already, experts say, holiday sales are off 7 percent from last year’s pace. But don’t sound any alarms just yet. Consumers seem only concerned, not panicked, and many say they remain optimistic about the economy’s long-term prospects, even as they do some modest belt-tightening.Consumers say they’re not in despair because, despite the dreadful headlines, their own fortunes still feel pretty good. Home prices are holding steady in most regions. In Manhattan, “there’s a new gold rush happening in the $4 million to $10 million range, predominantly fed by Wall Street bonuses,” says broker Barbara Corcoran. In San Francisco, prices are still rising even as frenzied overbidding quiets. “Instead of 20 to 30 offers, now maybe you only get two or three,” says john Deadly, a Bay Area real-estate broker. And most folks still feel pretty comfortable about their ability to find and keep a job.Many folks see silver lining to this slowdown. Potential home buyers would cheer for lower interest rates. Employers wouldn’t mind a little fewer bubbles in the job market. Many consumers seem to have been influenced by stock-market swing, which investors now view as a necessary ingredient to a sustained boom. Diners might see an upside, too. Getting a table at Manhattan’s hot new Alain Ducasse restaurant need to be impossible. Not anymore. For that, Greenspan & Co.may still be worth toasting.36. By “Ellen Spero isn’t biting her nails just yet” (Line 1, Paragraph 1), the author means .A. Spero can hardly maintain her businessB. Spero is too much engaged in her workC. Spero has grown out of her bad habitD. Spero is not in a desperate situation37. How do the pubic feel about the current economic situation?ConfusedA.B.OptimisticPanickedCarefree D.C.38. When mentioning “the $4 million to $10 million range”(Lines 3-4, Paragraph 3) the author is talking about .A. gold marketB. real estateC. stock exchangeD. venture investment39. Why can many people see “silver linings” to the economic slowdown?A. They would benefit in certain ways.B. The stock market shows signs of recovery.C. Such a slowdown usually precedes a boom.D. The purchasing power would be enhanced.40. To which of the following idea is the author likely to agree?A. A now boom, around the corner.B. Tighten the belt, the single remedy.C. Caution all right, panic not.D. The more ventures, the more chances.Part Ⅲ Vocabulary (10 points)Directions:In this part, there are 20 sentences with four choices below each sentence.

For each blank there are four choices marked A, B, C and D. Choose the one that best completes the blank. Then mark the corresponding letter on ANSWER SHEET 1.An Ohio State University study has linked behavior in young children 61 the type of job their mother has. Mothers with complex occupations that are self-directed and require working with other people 62 to have offspring with relatively low levels of behavior problems. The opposite held 63 when the jobs were routine, closely supervised, and dealt with things, rather than people.“A job that challenges and interests a mother and gives her an opportunity to exercise judgment and solve problems clearly has 64 consequences for her children’s behavior,” indicates 65 professor of sociology Elizabeth Mengaghan. Occupations with more positive conditions include management, sales, and teaching positions. Jobs that may be related to increased child behavior problems include book keeping, food service, and 66 line positions.Women who are supervised closely at work and made to 67 strict orders may be more likely to use this same style in 68 their kids. They may emphasize obedience to parental authority and the potential for 69 punishment. “We believe that the choice of such a parenting style may increase the 70 of behavior problems in children.” On the 71 hand, mothers whose jobs are less controlled by supervisors and 72 must work closely with other people probably rely less on physical punishment, 73 encouraging children to think about consequences of their actions and 74 responsibility for their behavior. 75 an approach encourages youngsters to follow parental demands 76 they aren’t being supervised because they have accepted parental values as their own. Moreover, mothers whose jobs don’t 77 constant supervision “ 78 problem-solving skills that they can bring to other parts of their life”.The research also found that those who have 79 challenging and interesting jobs provide better home environments for their children. The mothers give their offspring more intellectual stimulation and emotional support, and this, 80 turn, is linked to fewer behavior problem.with C.B.in D.onof61.A.D.tendedrelatedC.62.likely B.A.linkedD.thesamewrong63.A.true B.false C.64.

Write your translation on ANSWER SHEET 2.81. By now it’s hardly news that as education has risen to the top of the national agenda, a great wave of school reform has focused on two related objectives: more-stringent academic standards and increasingly rigorous accountability for both student and schools.82. In state after state, legislatures, governors, and state boards, supported by business leaders, have imposed tougher requirements in math, English, science, and other fields, together with new tests by which the performance of both students and schools is to be judged. In some places students have already been denied diplomas or held back in grade if they failed these tests. 83. In some states funding for individual schools and for teachers’ and principals’ salaries----and in some, such as Virginia, the accreditation of schools---will depend on how well students do on tests. More than half the states now require tests for student promotion or graduation.But a backlash has begun.84. In Virginia this spring parents, teachers, and school administrators opposed to the state’s Standard of Learning assessments, established in 1998, inspired a flurry of bills in the legislature that called for revising the test of their status as unavoidable hurdles for promotion and graduation. One bill would also have required that each new member of the sate board of education “take the eighth grade Standard of Learning assessments in English, mathematics, science, and social sciences” and that “the results of such assessments… be publicly reported.” 85. None of the bills passed, but there’s little doubt that if the system isn’t revised and the state’s high failure rates don’t decrease by 2004, when the first Virginia senior may be denied diplomas, the political pressure will intensify. Meanwhile, some parents are talking about Massachusetts-style boycotts.Part Ⅵ Writing(15 points)Directions:Write a composition of no less than 200 words about you opinions on academic plagiarism—the dishonest act in academic communication. Write your answer on ANSWER SHEET 2.。
