I have kept a record of informal conversations 21 some 300 students from at 22 twenty-one colleges and universities. The students were generally frank and direct in their comments 23 how course work could be better presented. Most of their remarks were kindly made with tolerance rather than bitterness----and frequently were softened by the fact that the students were speaking about some, not all, instructors. Nevertheless, 24 the following suggestions and comments indicate, students feel 25 with things as they are in the classroom.Professors should be 26 from reading lecture notes. “It makes their voices monotonous.”If they are going to read, why not 27 out copies of the lecture? Then we wouldn’t need to go to class. Professors should 28 repeating in lectures material that is in the textbook. “29 we’ve read the material, we want to discuss it or hear it elaborated on,30 repeated.”“A lo t of students hate to buy a required text that the professor has written only to have his lectures repeat it.”21. A. counting B. covering C. figuring D. involving22. A. best B. length C. least D. large23. A. at B. on C. of D. over24. A. if B. though C. as D. whether25.

A. avoid B. prevent C. refuse D. prohibit29. A. Until B. Unless C. Once D. However30. A. not B. or C. and D. yetPart ⅢREADING COMPREHENSION ( 30 points)Directions: In this part of the tests, there are six short passages for you to read. Read the passage carefully, and then answer the questionsthat follow. Then choose the best answer from the chioces markedA, B, C and D, and mark the corresponding letter with a single bar across the square brackets on your machine-scoring AnswerSheet.Passage OneThe e-book, you could argue, is environmentally friendly, which is true, but it is also incredibly counter-intuitive. Computer engineers spend a lot of their time coming up with ways to make computers ubiquitous (无所不在的) in consumer lives, and they’ve largely succeeded in that, which is part of the point. Many consumers have also been busy rejecting electronic banking, partly because we want a few tangible experiences leftin our lives, and handling money is one of those experiences. Reading a book, in a way, is an act of rebellion today. It’s a statement that despite the 35 channels coming in on the cable box, the billions of Web sites and other diversions, you’re going to read a book. This is something someone could have done in the 16th century, when the first books were printed in English.I used to attend a regular “salon”in Man hattan, where Internet people would meet, have dinner and discuss the latest trends. One of the sponsors of these social gatherings, who worked for a publisher, brought an e-book to the group, and passed it around. Everything about it bugged me; it w as characterless, flat and soulless. One might imagine reading the works of Bill Gates on it, but the thought of reading Thackeray or Dickens or Wilkie Collins or even John Steinbeck on it is a laughing matter.In other words, books are more than just words, they have —or used to have —decorative covers, because they are expressions of the author’s creativity. That’s why some people collect first editions. They want to own the book that was authorized by the writer, an edition he or she might have owned. As books age, they attain a certain patina (古色古香), reminding of the history the object has seen.31. According to the author, one drawback of computers is that .A. they require sophisticated computer literacyB. they arc interfering with our private livesC. they can be used only in a limited numbers of areasD. they deprive us of experiences of handling things32. Today, reading books is regarded as .A. creativeB. harmfulC. intellectualD. old-fashioned33. It is the author’s opinion that .A. it is ridiculous to read literary works on an e-bookB. readers find it odd to read Bill Gates’ works on an e-bookC. reading e-books is not very different from reading paper booksD. e-books will replace traditional books in the foreseeable future34. The last paragraph is mainly concerned with the ________ aspect of paperbooks.A. physicalB. intellectualC. estheticD. historical35. What is the author’s main purpose?A. To forecast the e-books’ future.B. To make a case against e-books.C. To suggest alternatives to printed books.D. To weigh the pro and con of e-books.Passage 2Of all the areas of learning, the most important is the development of attitudes. Emotional reactions as well as logical thought processes affect the behavior of most people.“The burnt child fears the fire”is one instance; another is the rise of despots (暴君) like Hitler. Both these examples also point up the fact that attitudes stem from experience. In the one case the experience was direct and impressive; in the other it wasindirect and cumulative. The Nazis were indoctrinated largely by the speeches they heard and the books they read.The classroom teacher in the elementary school is in a strategic position to influence attitudes.This is true partly because children acquire attitudes from those adults whose word they respect.Another reason it is true is that pupils often delve (挖掘)somewhat deeply into a subject in school that has only been touched upon at home or has possibly never occurred to them before. To a child who had previously acquired little knowledge of Mexico, his teacher’s method of handling such a suit would greatly affect his attitude toward Mexicans.The media through which the teacher can develop wholesome attitudes are innumerable. Social studies (with special reference to races, creeds and nationalities), science matters of health and safety, the atmosphere of the classroom…these are a few of the fertile fields for the inculcation of properemotional reactions.However, when children come to school with undesirable attitudes, it is unwise for the teacher to attempt to change their feelings by scolding them. She can achieve the proper effect by helping them obtain constructive experiences.To illustrate, first-grade pupils afraid of policemen will probably alter their attitudes after a classroom chat with the neighborhood officer in which he explains how he protects them. In the same way, a class of older children can develop attitudes through discussion, research, outside reading and all-day trips.Finally, a teacher must constantly evaluate her own attitudes, because her influence can be deleterious if she has personalprejudices. This is especially true in respect to controversial issues and questions on which children should be encouraged to reach their own decisions as a result of objective analysis of all the facts.36. The central idea conveyed in the above passage is that _______.A. attitudes affect our actionsB. teachers play a significant role in developing or changing pupils’attitudesC. attitudes can be changed by some classroom experiencesD. by their attitudes, teachers inadvertently affect pupils’ attitudes.37. A statement not made of implied in the passage is that _______.A.attitudes can be based on the learning of falsehoodsB. a child can develop in the classroom an attitude about the importanceof brushing his teethC.attitudes cannot easily be changed by rewards and lecturesD.the attitudes of elementary school-aged children are influencedprimarily by the way they were treated as infants38. The passage specifically states that _______.A.direct experiences are more valuable than indirect onesB.whatever attitudes a child learns in school have already beenintroduced at homeC.teachers should always conceal their own attitudes.D.Teachers can sometimes have an unwholesome influence on children39. The first and fourth paragraphs have all the following points in commonexcept _______.A.the importance of experience in building attitudesB.how fear sometimes governs attitudesC.how attitudes can be changed in the classroomD.how reading affects attitudes40. In the second paragraph, a substitute quotation to serve the writer’spurpose would be: _______.A.“poverty is the parent of revolution and crime.”B.“He that hath wife and children hath given hostages to fortune.C.“There is a great difference between a cunning man and a wise man.”D.“Nothing on earth consumes a man more quickly than the passion ofresentment.”Passage 3The world is undergoing tremendous changes. The rise of globalization, both economic and cultural that has swept throughout the world, has forged new ground as we enter the 21st century. But are the effects of globalization always positive? Some say no.Michael Tenet, head of the International Institute for Foreign Relations in Atlanta, is worried about current resentment throughout the world toward the rise of globalization. “Ever since the 1980s and the economic breakdown of the Asian Tigers in the late 1990s, there has been a re-evaluation of the role of globalization as a for ce for good,” he said, “Income in manycountries has declined and the gap between the most rich and the most poor has been worsened. Without further interference by governments, we could see a tragedy expressed in an increased level of poverty throughout t he Latin America and Asia.”Y et George Frank, an influential economist who works on Wall Street, sees no such danger. “E conomic liberation, increased transparency and market-based reforms have positive effect in the long run, even if market mechanism can produce short term destabilization problems,” he said. “What is most important is that barriers to trade continue to fall so that active competition for consumer goods reduces prices and in turn raises the average level of income.”Others feel that global ization’s cultural impact may be more important than its economic implications. Janice Y awee, a native of Africa, feels strongly that globalization is weakening her local culture and language. “Most of the world’s dialects will become extinct under globalization. We are paving the world with McDonald’s and English slang. It tears me up inside,” she said.However, ignoring the political dimensions of globalization has already had its cost. Nowhere was this made clearer than in the East Asian economic crisis of the late 1990s —particularly in Indonesia. In the wake of that crisis, the President Suharto’s regime was overthrown, and the entire country has been thrown into a mess. The Indonesian economy has contracted almost 50 percent, throwing tens of millions of people below the poverty line.Governments of different countries have had mixed responses to the wave of globalization. The United States is generally seen as an active proponent of greater free trade, andit certainly has enormous cultural influence by virtue of its near monopoly on worldwide entertainment. But other countries, most notably in Europe and developing nations, have sought to reduce the impact that globalization has on their domestic affairs.41. It can be inferred that Michael Tenor’s at titude toward globalization isprobably .A. strongly opposedB. cautiously agreedC. somewhat anxiousD. absolutely supportive42. According to the passage, George Frank .A. agrees with the comments made by Michael TenetB. consents the globalization is favorable to economyC. believes that the reduction of prices is due to the competitionD. thinks the instability is caused by the economic liberalization43. The words by Janice Y awee mean that .A. dialects need more protection by people in the worldB. informal English words are as popular as the McDonald's in the worldC. Janice Y awee’s local culture has vanished in the worldD. the impacts of globalization are great on cultures of the world44. The author cites the example of Indonesia in order to .A. prove the impact of globalization on the field of politicsB. show the economic crisis of the late 1990s in East AsiaC. support the successful economic and political reform in IndonesiaD. illustrate why the Suhatro’s regime collapsed45. This passage implies that .A. globalization is good for a country’s economic developmentB. globalization is widely accepted and advocated by peopleC. globalization is too influential on a country’s economy to be acceptedD. globalization is not always of great benef it to a country’s developmentPassage 4Some futurologists have assumed that the vast upsurge of women in the workforce may portend a rejection of marriage. Many women, according to this hypothesis, would rather work than marry. The converse of this concern is that the prospects of becoming a multi-paycheck household could encourage marriage. In the past, only the earnings and financial prospects of the man counted in the marriage decision. Now, however, the earning ability of a woman can make her more attractive as a marriage partner. Data shows that economic downturns tend to postpone marriage because the parties cannot afford to establish a family or are concerned about rainy days ahead. As the economy rebound, the number of marriages also rises.Coincident with the increasing women working outside the home is the increase in divorce rates. Y et, it may be wrong to jump to reply simple cause-and-effect conclusions. The impact of a wife’s work on divorce is no less cloudy than its impact on marriage decisions. The realization that she can be a good provider may increase the chances that a working wife will choose divorce over an unsatisfactory marriage. But the reverse is equally plausible. Tensions grounded in financial problemsoften play a key role in ending a marriage. Given high unemployment, inflationary problems, and slow growth in real earnings, a working wife can increase household income and relieve some of these pressing financial burdens. By raising family’s standard of living, a working wife may strengthen her family’s financial and emotional stability.Psychological factors also should be considered. For example, a wife blocked from a career outside the home may feel caged in the house. She may view her only choice as seeking a divorce. On the other hand, if she can find fulfillment through work outside the home, work and marriage can go together to create a stronger and more stable union.Also a major part of women’s inequality in marriage has been due to the fact that in most cases, men have remained the main breadwinner. With higher earning capacity and status occupations outside the home comes the capacity to exercise power, within the family. A working wife may rob a husband of being the master of the house. Depending upon how the couple reacts to these new conditions, it could create a stronger equal partnership or it could create new insecurities.46. The word “portend” in P aragraph 1 is closest in meaning to “________”.A. defyB. signalC. suffer fromD. result from47. It is said in the passage that when the economy slides, .A. men would choose working women as their marriage partnersB. more women would get married to seek financial securityC. even working women would worry about their marriagesD. more people would prefer to remain single for the time being48. One reason why women with no career may seek a divorce is that _ .A. they feel that they have been robbed of their freedomB. they are afraid of being bossed around by their husbandsC. they feel that their partners fall to live up to their expectationsD. they tend to suspect their husbands' loyalty to their marriage49. If women find fulfillment through work outside the home, .A. they are more likely to dominate their marriage partnersB. their husbands are expected to do more houseworkC. their marriage ties can be strengthenedD. they tend to put their career before marriage50. Which of the following statements can best summarize the author’s viewin the passage?A. The stability of marriage and the divorce rate may reflect the economicsituation of the country.B. Even when economically independent, most women have to strugglefor real equality in marriage.C. In order to secure their marriage, women should work outside the homeand remain independent.D. The impact of the growing female workforce on marriagevaries fromcase to case.Passage 5In evolutionary terms, humans are relative newcomers to earth, but in a short time they have established themselves as the most successful and dominant species. As Carl Sagan has commented, humans arrived late in December if we consider evolutionary time in terms of a calendar year. As our earliest ancestors left the forest to feed in the savannas and finally to form hunting societies on the open plains, their minds and behavior changed.The theory of natural selection provides an explanation of the evolutionary process. This theory is based on Charles Darwin’s observations of many animal species around the world. Darwin pointed out that organisms reproduce at rates that could lead to enormous increases in population sizes of most species.However, despite these massive reproductive capacities, population size tends to remain fairly constant.Darwin stressed that there is extensive variability-sometimes referred to as genetic diversity-among individuals in a species. Some of these variations appear advantageous for survival. Darwin argued that individuals characterized by these beneficial characteristics would be more likely to survive and succeed in reproducing themselves. Gradually, the organisms with the favorable characteristics would comprise a greater proportion of the population, and over a long period of time, the reproductive advantage could produce a gradual modification of the whole population. However, if environmental conditions change, new sets of characteristics might be favored and the whole process could move off in a different direction.Evolution proceeds at a very slow pace indeed. For example, the lines leading to the emergence of human beings and the great apes began to diverge about 14 million years ago. Modern man came into existence about 50, 000 years ago. The beginning of civilization as we know it began about 10, 000 years ago. In the ensuring years there have been no sweeping evolutionary changes in humans. This is not surprising because we have existed for only about 50, 000 years and it takes much longer fora mammalian species to develop.51. Which of the following statements is certain?A. Humans emerged later than most animals on earth.B. Humans came into existence when the earth was cold.C. Humans became hunters 10,000 years ago.D. No evolution has taken place in humans in the last 10,000 years.52. Why does population size remain relatively constant?A. Organisms do not reproduce at high enough rates.B. Few organisms are characterized with favorable characteristics.C. Some variations in a species fail to survive.D. Evolution takes a longer time than could be imaged.53. According to Darwin, evolution is chiefly determined by _______.A. biological factorsB. environmental factorsC. interspecies factorsD. reproduction time54. The word “diverge” in paragraph 4 is closest in meaning to “__”A. renderB. corruptC. deviateD. derive55. Evolution in a species often starts_______.A. collectivelyB. in some individualsC. suddenlyD. in a sweeping mannerPassage 6Mass production, the defining characteristic of the Second Wave economy, becomes increasingly obsolete as firms install information intens ive, often robotized manufacturing systems capable of endless deep variation, even customization, The revolutionary result is, in effect, the de-massification of mass production.The shift toward smart flex-techs promotes diversity and feeds consumer choice to the point that a Wal-Mart store can offer the buyer nearly 110,000 products in various types, sizes, models and colors to choose among.But Wal-Mart is a mass merchandiser. Increasingly, the mass market itself is breaking up into differentiated niches as customer needs diverge and better information makes it possible for businesses to identify and serve micro-markets. Specialty stores, boutiques, superstores, TV home-shopping systems, computer-based buying, direct mail and other systems provide a growing diversity of channels through which producers can distribute their wares to customers in an increasingly de-massified marketplace. When we wrote Future Shock in the late1960s, visionary marketers began talking about “market segmentation.”Today they no longer focus on “segments”buton “particles”—family units and even single individuals.Meanwhile, advertising is targeted at smaller and smaller market segments reached through increasingly de-massified media. The dramatic breakup of mass audiences is underscored by the crisis of the once great TV networks, ABC, CBS and NBC, at a time when Tele-Communications, Inc. of Denver, announces a fiber-optic network capable of providing viewers with five hundred interactive channels of television. Such systems mean that sellers will be able to target buyers with even greater precision. The simultaneous de-massification of production, distribution and communication revolutionizes the economy and shifts it from homogeneity toward extreme heterogeneity.56. What would be a proper title for this passage?A. Future ShockB. De-massificationC. Changing TrendD. Market Segmentation57. Which is true about “mass production” according to the author?A. It promotes further development in manufacturing systems.B. It defines the Second Wave economy and will last.C. It involves intensive information, automation, and customization.D. It is becoming dated for the present economy.58. The author calls those marketers “visionary” mainly because_______.A. they began talking about “market segmentation” in 1960s.B. they focus on “market particles.”。

In the past, interspecies hybridization was dismissed as a possible solution, since hybrids are rarely as vigorous as purebred species. However, current research on hybridization suggests that although some hybrids are not as virile as either of the parent species, they are often strong enough to pass their traits on. Scientists have also found hybrid species, such as certain types of corn, that are stronger than their parent species, a phenomenon known as “hybrid vigor”. These findings suggest that hybridization plays a far more important role in evolution than previously suspected.41. It can be inferred that some scientists previously believed that ________.A. the details of evolutionary theory may never be fully understoodB. hybrid plants lack the ability to reproduce by themselvesC. plants that are robust possess an evolutionary advantageD. purebred plants play a relatively minor role in evolution42. The passage implies that most scientists will adopt a theory that ________.A. includes elements about which little is knownB. cannot be proven by experimental meansC. involves ideas which will likely be disproved laterD. has limited real-world applications2Though most people know the definition of the word “boycott”, few know its origin. Named for Captain Charles Boycott, the word as we know it owes less to him than to Irish nationalist Charles Parnell. Parnell organized Irish farmers and convinced them to fix their rent rates. When Boycott refused, Parnell unleashed the power of the people. A band of hostile peasants forced the Captain’s servants to leave. There were no laborers to gather the harvest and no stablemen to ca re for the animals. Boycott was not allowed to enter stores or make purchases. Eventually, Boycott and his wife fled Ireland, and Parnell was hailed as the workingman’s hero.43. The passage is best summarized by which of the following?A. The origin of a word is explored, and an explanation for its popularity is given.B. A word is introduced, and a history of its usage is related.C. An event is described as the reason behind a shift in a word’s meaningD.A word is introduced, and the history of its coining is related.44. It can be most reasonably inferred from the passage that _______.A. Boycott’s land was not harvested that yearB. the townspeople referred to were sympathetic to the farmersC. Parnell was popular among all IrishmenD. the farmers threatened Boycott with physical harm3Passage 1:No major political election in the United States has ever been decided by one vote. In fact, a single vote contributes only about one millionth of the total result of the average statewide election. Considering how numerically insignificant a single vote is, is there any rational justification for an individual to vote? In order to answer this question, one must look past the mere numerical value of a vote. An individual’s vote is valuable as a measure of that individual’s belief in the system of government, which likewise indicates the degree to which a person feels included in the greater social order.Passage 2:When recently asked whom he voted for in the last presidential election, a friend of mine replied, “I didn’t bother.” With a rather bored shrug, and little embarrassment, my friend continued, “I t’s not like it matters. My vote wouldn’t have changed the outcome.” I couldn’t help thinking then that the argument was uncannily persuasive. If I had stayed in bed that morning, the result would likewise be exactly the same. But the argument does not hold up under scrutiny. If democracy means rule by the people, and not by any one individual, then why should the vote of just one person determine the outcome of an election? No person, no matter who he is, should be able to change the greater will of a collected group. The idea of doing so is simply undemocratic.45. Which of the following, if true, would most strengthen the hypothesis of the author of Passage1 concerning voting behavior?A. Historical documents reveal that may local elections have been decided by a single vote. B.A new study finds that many Americans feel that voting is a burdensome inconvenience. C.A poll of American citizens indicates that most citizens consider voting an important communal duty.D.V oting records show that most people who vote participate in both national and local elections.46. The author of Passage 1 would most likely conclude which of the following about the “friend”described in Passage 2?A. The friend likely feels that he is disconnected from the society in which he lives. B.Unless he changes the outcome of an election, the friend is unlikely to ever vote.C. The number of people today who act as the friend does indicates a fundamental flaw in society.D.People who don’t feel the need to vote are generally satisfied with life as it is.47. Both passages serve to discourage the ________.A.inclination of Americans to invent excuses for not votingB.tendency of voters to avoid making difficult decisionsC.valuation of a vote by its ability to decide an electionD.apathy that some voters feel about the lack of real choices48. The final sentence of Passage 2 serves to ________.A.explain the rationale behind a behavior patternB.denounce the actions of those who do not voteC.show the subtle irony of the friend’s argumentD.offer a solution to a pressing problem41 Laboratory research is at the heart of scientific life; scientists’ real work consists of testing out ideas that come to them as they ponder the mysteries of the world around them. A natural biologist walks through a city park or across a suburban lawn and is half-consciously wondering: Why two leaves instead of three? Why pink flowers instead of white? Such rumination goes on without end in a scientist’s mind, a continuous accompaniment to the rhythm of daily life. Whatever a scientist is doing—reading, cooking, talking, playing—science thoughts are always there at the edge of the mind. They are the way the world is taken in; all that is seen is filtered through an ever present scientific musing.2 How a would-be scientist decides on a discipline, settles on a problem, and goes to work is often as much a mailer of chance as it is of temperament. One can easily become a chemist or a neuroanatomist because of where one went to school or whose influence one happened to come under as because of a compelling early response to the logic of chemistry or the beauty of the human nervous system. No matter. Once the discipline is established, the problem chosen, and the scientist immersed in the work, he or she becomes as persuaded as need be of the centrality and urgency of the particular work being done. Such adaptive myopia is necessary in science because the grinding, repetitive minuteness of daily laboratory work is so time-consuming (for weeks, months, even years at a time) that, often, even to remember the original impetus for the work is a psychological trick of the highest order. To stimulate the memory back into existence with fair regularity, one must believe in the fundamental importance of what one is doing. Those who do are the most energetic, vital, exciting, and excited of scientists.3 Carol Steiner, a geneticist, comes up with a fine metaphor for how to make a working proposition of scientific mystery. “Imagine,” she says, “that you have a jigsaw puzzle with no picture printed on it. All you have are pieces you haven’t a clue how to make sense of. The pieces are your separate scientific observations. Here’s an e xample of how you might try to get a handle on the puzzle:4 “We have a microorganism with a secretory structure on one end. We know this structure is always on the same place in the cell and that the position of this structure is inherited. The question we want to answer is, how can inherited information be translated into positional information? Why in that one place and no place else? Is the genetic code involved, and if so, how? The answer will tell us how the genes work in concert with the rest of the cell to put things where they belong.5 “In order to gather pieces of the jigsaw puzzle (that is, pieces of information), we poke at the cell. We change it a little … . A specific mutation that altered the membrane structure of the cell was found to turn off the synthesis of the secretory structure. This was a piece of the jigsaw puzzle. But just one piece. Because we hadn’t a clue as to how this had happened or could happen.” Steiner indicates that there will be many further questions that will suggest experiments whose results may allow us to print pictures on the pieces of the jigsaw puzzle: “Not put the puzzle together, mind you. But help us think about what the picture will ultimately look like.”6 The realized picture on Carol Steiner’s jigsaw puzzle i s the map of gene expression laid out clearly with all roads, pathways, connecting signal points, and railway junctions marked so that any tourist can find his or her way in this beautiful country, which is confusing only when one is wandering about in ignorance—as we all are now—with a highly incomplete map.49. The primary purpose of the passage is to convey information about the ________.A. occupational hazards encountered by laboratory workers.B. problem-solving skills taught by chemists and neuroanatomistsC. professional collaboration necessary for geneticistsD. thought processes distinctive to research scientists50. In Line 1, the author characterizes “laboratory research” as something that is________.A. fundamentalB. ambitiousC. challengingD. time-consuming51. The author indicates that the process of “rumination” (paragraph 1) is________.A. subjectiveB. vexatiousC. incessantD. innovative52. In paragraph 2, “No matter” dismisses as irrelevant the means by which________.A. science students learn research skillsB. scientists choose research specialtiesC. laboratory reports explain methodologiesD. scientific knowledge is perceived by the public53. The “memory” referred to in paragraph 2 is that of the ________.A. initial fascination with a scientific goalB. steps required to establish scientific truthC. day-to-day repetitiveness of the workD. relevant training in the academic field54. The passage implies that the discovery of the “specific mutation”(paragraph 5) was most significant for________.A. demonstrating the random nature of scientific breakthroughsB. proving that multiple factors affect microorganismsC. providing a clue to the solution of a research questionD. justifying the expense of a major research project55. Which b est describes the function of Steiner’s account of her research in the overall development of the passage?A. A digression from the author’s central argumentB. A refutation of criticisms raised earlier in the passageC. An observation that challenges previous assertionsD. An example that expands upon preceding generalization51 The downslope movement of rock, mud, or other material under the influence of gravity is known as mass wasting. While the angle of the slope is a major factor in the potential for mass wasting, the slope is not the sole determiner of mass wasting events. Water plays a significant role, especially where it is plentiful during the rainy season. Earthquakes may cause rockslides, mudflows, and other mass movements. Factors such as the presence or absence of vegetation andhuman activities can also influence the potential for mass wasting.2 One way to classify mass wasting processes is on the basis of the material involved, such as rock, debris, earth, or mud. The manner in which the material moves is also important and is generally described as a fall, a slide, or a flow. A fall occurs when weathering loosens boulders from cliffs or rock faces, causing the boulders to break away and fall. A slide takes place whenever material remains fairly coherent and moves along a well-defined surface. A flow involves the movement of debris containing a large amount of water.3 Many mass wasting processes are described as slides. Rockslides occur when a coherent mass of rock breaks loose and slides down a slope as a unit. If the material involved is mostly separate pieces, it is called a debris slide. Slides are among the fastest and most destructive mass movements. Usually rockslides occur in a geologic setting where the rock layers are inclined, or where there are joints and fractures in the rock that are parallel to the slope. When such a rock unit is undercut at the base of the slope, it loses support and the rock eventually collapses. Rain or snowmelt can trigger a rockslide by wetting the underlying surface to the point that friction can no longer hold the rock in place. The fastest type of slide is a rock avalanche, in which a mass of rock literally floats on air as it moves downslope. The high speed of a rock avalanche is the result of air becoming trapped and compressed beneath the falling mass of debris, allowing it to move down the slope as a buoyant sheet.4 Mudflows are relatively rapid mass wasting events that involve soil and a large amount of water. Because of their fluid properties, mudflows follow canyons and stream channels. Mudflows often take place in semiarid mountainous regions and on the slopes of some volcanoes. Although rainstorms in semiarid regions are infrequent, they are typically heavy when they occur. When a rainstorm or rapidly melting snow creates a sudden flood, large quantities of soil and loose rock are washed into nearby stream channels because there is usually little or no vegetation to anchor the surface material. The result is a flowing mass of well-mixed mud, soil, rock, and water. The consistency of the mudflow may be similar to that of wet concrete, or it may be a soupy mixture not much thicker than muddy water. The water content influences the rate of flow across the surface. When a mudflow is dense, it moves more slowly, but it can easily carry or push large boulders, trees, and even houses along with it.5 In dry mountainous areas such as southern California, mudflows are a serious hazard to development on and near canyon hillsides. The removal of native vegetation by brush fires has increased the probability of these destructive events.Past mudflows have contributed to the buildup of fan-shaped deposits at canyon mouths. Such fans are relatively easy to build on and often have scenic views, so many have become desirable sites for residential development. However, because mudflows occur infrequently, homeowners are often unaware of the potential danger of building on the site of a previous mudflow.6 Highly fluid, fast-flowing mudflows incorporate fine-grained sediment and are common after volcanic eruptions that produce large volumes of volcanic ash. Mudflows containing volcanic debris are called lahars, a word originating in Indonesia, a region that experiences many volcanic eruptions. Lahars occur when highly unstable layers of ash and debris become saturated with water and flow down steep volcanic slopes along stream channels. In the northwestern United States, the eruption of Mount St. Helens in 1980 created several lahars that raced down the valley of the Toutle River, altering the landscape in a relatively short period.56. All of the following are given as factors in mass wasting EXCEPT ________.A.the angle of the slopeB.the presence of waterC.the absence of plantsD.the type of mineral57. The name of a mass wasting process is a reflection of ________.A.the area in which the movement occursB.the material that is moved and the way it movesC.the rate of movement relative to other processesD.the mass and volume of the material involved58. The word “trigger” in paragraph 3 is closest in meaning to ________.A.preventB.imitateC.causeD.decrease59. Why does a rock avalanche move faster than other types of rockslides?A.The rock moves over a layer of compressed air.B.The rainfall is heavy where avalanches occur.C.The rock breaks apart as it moves downslope.D.The angle of the slope is almost vertical.60. The underlined word “that” in paragraph 4 refers to ________.A.resultB.consistencyC.mudflowD.mixture61. Which sentence below best expresses the essential information in the underlined sentence in paragraph 5? Incorrect choices change the meaning in important ways or leave out essential information.A.Fire has destroyed much of the original vegetation, so mudflows are now more likely.B.More damage to vegetation is caused by brush fires than by any other natural event.C.It is necessary to remove dead and damaged vegetation after a mudflow but not after a fire.D.Fires occur frequently in areas where the vegetation has been cleared for development. 62. What can be inferred from paragraph 5 about mudflows in some parts of southern California?A.Mudflows rarely occur more than once in the same location.B.Mudflows cause the worst damage in areas that are heavily forested.C.Mudflows occur more often than other natural disasters such as fires.D.Mudflows are so dangerous because people do not expect them to occur.63. Why does the author use the word “raced” in paragraph 6 while describing the lahars caused by the eruption of Mount St. Helens?A.To show that lahars are faster than rock avalanchesB.To state ironically that lahars do not actually move quicklyC.To emphasize the fast speed of laharsD.To explain why people could not outrun the mudflows64. Look at the four squares and, which indicate where the following sentence could be。

Racing cars serve as high-speed 41 . some athletes receive most of their money from advertisers. One 42 basketball player earned $ 3.9 million by playing ball. Advertisers paid him nine times that much to 43 their products. There is no escape. Commercial ads are displayed on walls, buses and trucks. They decorate the inside of taxis and subways ----even the doors of public toilets. 44 messages call to us in supermarkets, stores, elevators -----and 45 we are on hold on the telephone. In some countries so much advertising comes through the mail that many recipients proceed directly from the mailbox to the nearest wastebasket to 46 the junk mail. 47 Insider’s Report, published by McCann-Erickson, a global advertising agency, the estimated 48 of money spent on advertising worldwide in 1990 was $ 275.5 billion. Since then, the figures have 49 to $ 411.6 billion for 1997 and a projected $ 434.4 billion for 1998. Big money.What is the effect of all of this ? One analyst 50 it this way: “Advertising is one of the most powerful socializing forces in the culture. Ads sell more than products. They sell images, values, goals , concepts of who we are and who we should be. They shape our attitudes and our attitudes shape our behaviour.36. A lonely B alone C singly D individually37.

This is hardly surprising, since a single nuclear bomb can destroy an entire city. Yet, unlike smaller arms, these immensely powerful weapons have not been used in war in over 50 years.Historian John Keegan writes, “Nuclear weapons have, since August 9, 1945, killed no one. The 50,000,000 who have died in war since that date have for the most part, been killed by cheap, mass-produced weapons and small ammunitions, costing little more than the transistor radios which have flooded the world in the same period. Because small weapons have disrupted life very little in the advanced world, outside the restricted localities where drug-dealing and political terrorism flourish, the populations of the rich states have been slow to recognize the horror that this pollution has brought in its train.”Why have small arms become the weapons of choice in recent wars? Part of the reason lies in the relationship between conflict and poverty. Most of the wars fought during the 1990s took place in countries that are poor----too poor to buy sophisticated weapon systems. Small arms and light weapons are a bargain.For example, 50 million dollars, which is approximately the cost of a singlemodern jet fighter, can equip an army with 200,000 assault rifles.Another reason why small weapons are so popular is that they are lethal. A single rapid-fire assault rifle can fire hundreds of rounds a minute. They are also easy to use and maintain. A child of ten can be taught to strip and reassemble a typical assault rifle. A child can also quickly learn to aim and fire that rifle into a crowd of people.The global traffic in guns is complex. The illegal trade of small arms is big. In some African wars, paramilitary groups have bought billions o f dollars’ worth of small arms and light weapons, not with money, but with diamonds seized from diamond-mining areas.Weapons are also linked to the illegal trade in drugs. It is not unusual for criminal organizations to use the same routes to smuggle drugs in one direction and to smuggle guns in the other.51. It is implied in the passage that __________A small arms-control is more important than nuclear arms-control.B the nuclear arms-control talks can never reach an agreement.C the power of nuclear weapons to kill people has been diminished.D nuclear weapons were the topic of arms-control talks 50 years ago.52. The advanced world neglect the problems of small arms because ____A They have to deal with drug-dealing and political terrorism.B They have no such problems as are caused by small weapons.C They have not recognized the seriousness of the problems in time.D They face other more important problems such as pollution.53. Which of the following is NOT mentioned as the reason for the prevalence of small arms?A Small arms are cheap.B Small arms are powerful .C Small arms are easier to use.D Small arms are easier to get54. We can conclude from the passage that ____A small arms are not expensive in the black-market.B it is unfair to exchange small arms for diamond.C Criminals use the same passage to smuggle drugs and small arms.D where there are drugs, there are small arms.55. The best title for this passage is ____A Small Arms Talks, Not Nuclear Arms Talks.B Neglect of Small Arms ControlC Global Traffic in Small ArmsD Small Arms, Big Problems.Passage Two In order to combat sickness, many doctors rely heavily on prescribing medicines that are developed and aggressively advertised by pharmaceutical companies. Significantly, the world market for such drugs has skyrocketed in recent decades, from just a few billion dollars a year to hundreds of billions of dollars annually. What had been a consequence?Medically prescribed drugs have helped many people. Yet, the health of some who take drugs has either remained unchanged or become worse. So, recently some have turned to using other methods of medical treatment.In places where modern, conventional medicine has been the standard of care, many are now turning to what have been called alternative, or complementary, therapies. “The Berlin Wall that has long divided alternative therapies from mainstream medicine appears to be crumbling,” said Consumer Reports of May 2000.The Journal of the American Medical Association(JAMA) observed, “Alternative medical therapies such as the use of herbs, functionally defined as interventions neither taught widely in medical schools nor generally available in U. S. hospitals, have attracted increased national at tention from the media, the medical community, governmental agencies, and the public.”In the past, conventional medical practitioners have been skeptical about alternative medical practices, but 75 medical schools in the United States currently offer elective course work on alternative medicine, including Harvard, Stanford, University of Arizona, and Yale.JAMA noted, “ Now an estimated 3 in 5 individual seeing a medical doctor for a principal condition also used an alternative therapy.And outside the United States, alternative medicine is popular throughout the industrialized world.”The trend toward integrating alternative therapies with conventional ones has long been a general practice in many countries. As JAMA concluded, “There are no longer t wo types of medicine, conventional and complementary. There is only good medicine and bad medicine.”56. This passage suggests that pharmaceutical companies ____A pay doctors for prescribing their drugs.B have raised the prices of their products sharply in recent years.C spend more money on their advertisements than on their products.D have produced some ineffective drugs.57. The sentence “The Berlin Wall …. Appears to be crumbling” in the third paragraph implies that _____A the restrictions on the practice of alternative therapies will be abolished.B there are still strict restrictions on the practice of alternative drugs.C conventional medicine and alternative therapies are incomparable.D conventional medicine and alternative therapies are completely different remedies.58. According to the passage, alternative therapies _____A are widely taught in the U.S. medical schools now.B have been approved by U. S. government.C have been used by many American patients.D are as popular as conventional medicine.59. JAMA seems to suggest that ____________A U. S. government should meet the increasing demands for alternative therapies.B a medicine is good after it proves to be beneficial to the patients.C pharmaceutical companies should cover the cost of alternative therapies.D conventional medicine and alternative medicine should join hands.60. It is implied in the passage that ._____________A we should take as little western medicine as possible.B the prices of the prescribed medicine should be reduced.C herbal medicine will be accepted by more Americans.D without the help of alternative medicine, good health can not be guaranteed.Passage Three Our Milky Way galaxy could contain up to 1 billion Earth-like planets capable of supporting life, scientists announced last week.The theoretical abundance of habitable worlds among the estimated 200 billion stars of our home galaxy suggests that more powerful telescopes might glimpse the faint signature of far-off planet, proving that, in size and temperature at least, we are not alone in the universe.Solar systems such as Earth’s, in which planets orbit a star, have been discovered. Astronomers have identified almost 100 planets in orbit around other suns. All are enormous, and of the same gaseous make-up as Jupiter.Barrie Jones of the Open University in UK and his colleague Nick Sleep have worked out how to predict which of the newly discovered solar systems is likely to harbor Earth-like planets.Using a computer, they have created mathematical models of planetary systems and seeded them with hypothetical Earths in “Goldilocks zone” orbits, where it is neither too hot too cold to support life.The computer simulates which of these model Earths is likely to be kicked out of its temperature orbit by gravitational effects of the monster planets, and which is likely to survive.The solar system most like ours discovered so far is 51 light years away, at the star 47 Ursae Majoris, near the group of stars known as the Great Bear.Astronomers have discovered two planets orbiting 47 Ursae Majoris----One is two and half times the size of Jupiter, the other slightly smaller. Both planets are relatively close to the Goldilocks zone, which is further out than ours because 47 Ursae Majoris is older, hotter and brighter than the sun. “It’s certainly a system worth exploring for an Earth-like planet and for life,” said Jones. The requirement for a life-supporting zone in any solar system is that water should be able to exist in a liquid state.NASA and its European counterpart, ESA, plan to launch instruments in the next 10 years which could produce pictures of Earth-sized planets.61. It is suggested in this passage that _______________A scientists have found evidence to prove there are many Earth-like planets in our galaxy.B Theoretically there are a great number of Earth-like planets capable of supporting life.C our Earth is the only planet in our galaxy that can support life.D with more powerful telescope, scientists will be able to find more galaxies in the universe62. The “Godilocks zone” mentioned in the 5th paragraph most probably means _________A a certain fixed distance between a planet and sun.B a range in the universe in which th e planets’ temperature is suitable for life.C a range in the universe in which the planets can receive enough sunlight.D a mathematical model to measure the size of the planetary system.63. Barrie Jones and Nick Sleep have found ____________A 100 planets orbiting around other stars like our sun.B many planets’ atmosphere has the same composition as Jupiter.C the ways to tell which solar system may have Earth-like planets.D a mathematical model to measure the distance of newly found solar-systems.64. So far, the solar system most like ours that has been discovered is _______A in the group of stars known as Great Bear.B 2.5 times as big as Jupiter.C smaller than our system.D impossible for us to reach at present time.65. The most important requirement to have a life-supporting zone in any solar system is that it must have _____A enough water and proper temperature.B enough oxygen and hydrogen.C enough air and sunlight.D enough water in any state.Passage Four Having abandoned his call for higher gasoline prices, Vie President Al Gore has another idea to get people out of their cars: Spend billions on mass transit ----$ 25 billion to be exact. Last week, Gore unveiled his “Keep America Moving” initiative, which will spend $25 billion on upgrading and improving mass-transit systems nationwide. According to Gore’s self-proclaimed “new way of thinking”, all that’s necessary to reduce traffic congestion is to “give people a choice.”The federal government has been tryin g to “give people a choice” for decades to little effect. Portions of the federal gasoline tax have already been used to support urban bus and rail systems. Despite years of subsidies, few urban-transit systems run in the black. They don’t do much to reduce congestion either. No matter how much the tax-payers paid for the planned transit systems.Americans prefer the autonomy offered by their automobiles.The vice president praised the Portland light-rail system as an example of how good mass transit can be. Yet Portland’s experience is more cautionary tale than exemplary model. Research by the Cascade Policy Institute demonstrates that Portland’s Metro has been a multi-million-dollar mistake. According to Metro’s own figures, the light-rail system is doing little to reduce congestion, as most of its riders used to ride the bus. Those riders that do come off the roads, come at an incredible price: $ 62 per round trip. Road improvements and expansion would do far more to reduce congestion at a fraction of t he cost, but they wouldn’t attract the same volume of federal funds.66. According to the author, the mass-transit systems____A are characterized by low consumption of gasoline.B have contributed little to the improvement of the traffic.C aim at monitoring the public traffic.D are financially profitable.67. What does the author say about the federal government?A It has recently begun to address the problem of traffic congestion.B It fails to provide enough funds to help reduce traffic congestion.C Its attempt to reduce traffic congestion is successful but costly.D It has not done much to reduce congestion by improving roads.68. What is said about Americans’ attitude toward the transit systems?A They are reluctant to pay taxes to support the transit systems.B They think driving their own cars is more convenient.C They prefer the policies of improving and expanding roads.D They think there should be more choices in transportation.69 In the third paragraph, the underlined expression “cautionary tale” most probably means ____A an incredible storyB an untrue storyC a story giving a warningD a story teaching a moral lesson70. Which of the following statements would the author probably agree to ?A In spite of federal funds, most urban-transit systems have financial problems.B The American public should become more aware of the need to reduce traffic congestion.C The attempt to expand roads would be as costly as the one to build a light-rail system.D The federal gasoline tax should be raised to support urban-transit system.Passage Five In all of the industrial countries and many less developed countries, a debate along the lines of government vs. business prevails. This struggle has gone on for so long and is so pervasive, that many who participate in it have come to think of these two social institutions as natural and permanent enemies, each striving to oppose the other.Viewing the struggle in that format diminishes the chance of attaining more harmonious relations between government and business. Moreover, if these two are seen as natural and deadly enemies, then business has no long-range future. It is self-evident that government, as the only social instrument that can legally enforce its will by physical control, must win any struggle that is reduced to naked power.A more realistic, and most constructive, approach to the conflict between business and government starts by noticing the many ways in which they are dependent on each other. Business cannot exist without social order. Business can and does generate its own order, its own regularities of procedure and behaviour; but at bottom these rest upon more fundamental patterns of order which can be maintained and evolved by the political state.The dependence of government on business is less absolute. Governments can absorb direct responsibility for organizing economic functions. In many cases, ancient and modern, government-run economic activities seem to have operated at a level of efficiency not markedlyinferior to comparable work organized by business. If society’s sole purpose is to achieve a bare survival for its members, there can be no substantial objection to governmental absorption of economic arrangements.71. Many people think go vernment and business are “enemies” because ____A the struggle between the two parties has always existed.B they based their belief on the experience of the industrial countries.C they believe that government can do better than business in economic activities.D the struggle between the two parties is so fierce that neither will survive in the end.72. The third paragraph mainly discusses___________A how government and business depend on each other.B why social order is important to business activities.C Why it is necessary for business to rely on government.D how business can develop and maintain order.73. What does the passage say about economic activities organized by government?A They mostly aim at helping people to survive.B They can be conducted as well as those by business.C They are the ones that business can’t do well.D They are comparatively modern phenomena.74. We can conclude from the passage that ____A it is difficult for government and business to have good relations.B it is difficult to study the relations between government and business.C government should dominate economic activities.D government and business should not oppose each other .Passage Six Standing up for what you believe in can be tough. Sometimes it’s got to be done, but the price can be high.Biochemist Jeffrey Wigand found this out the hard way when he took on his former employer, tobacco giant Brown & Williamson, over its claim that cigarettes were not addictive.So too did climate modeler Ben Santer when he put his name to a UN report which argued that it is people who are warming the planet. Both men found themselves under sustained attacks, Wigand from Brown & Williamson, Santer from the combined might of the oil and car industries.The two men got into their dreadful predicaments by totally different routes. But they had one thing in common---they fought powerful vested interests (既得利益者)with scientific data that those interests wished would go away.Commercial companies are not, of course, the only vested interests in town. Governments have a habit of backing the idea of whoever pays the most tax. Academia also has its version: scientific theories often come with fragile egos and reputations still attached, and supporters of those theories can be overly resistant to new ideas.For example, Alfred Wegener’s idea that the continents drift across the surface of the planet was laughed at when he proposed it in 1915. this idea was only accepted finally in the 1960s, when plate tectonics came of age. More recently, in 1982, Stanley Prusiner was labeled crazy for his controversial suggestion that infectious diseases such as BSE(疯牛病)were caused by a protein that self-replicated. A decade later, the notion had gained ground. Finally , in 1997, he received a Nobel Prize for his idea.Western science has always thrived on individualism---- one person’s ambition to topple a theory. So independence of thought is crucial.But this applies not only for scientists, but also their institutions.With governments and commercial sponsors increasingly pulling the strings of university research---- perhaps it’s time to spend some lottery money, say, on truly independent research.Overcoming scientists’ inertia will be much more dif ficult.Yet we can’t afford to be slow to hear new ideas and adapt to them. Back in the 1950s, if governments had taken seriously the findings of epidemiologist Richard Doll about the link between smoking and lung cancer, millions of people would have been spared disability and premature death.75. One of the ideas that are highlighted in the passage is that __________A individuals have greater chance of success in scientific research than collectives.B personality plays a crucial role in the advance of science.C originality of thinking is the key to the advance of science.D the intelligence of scientists is of vital importance to scientific achievements.76. Jeffrey Wigand’s idea about the nature of cigarette__________A was similar to that of the tobacco company.B sounded ridiculous to the general public .C was reached purely out of personal interestsD should be regarded as scientifically true.77. Jeffrey Wigand was attacked by the tobacco giant because _____A his idea could lead to a financial loss for the company.B he had been eager to defeat his company.C his idea was scientifically invalid.D he had long been an enemy of the company.78. The underlined phrase “place tectonics” in the 5th paragraph probably refers to ____A the study of the structure of the earthB scientific study of the climate of the earth.C the theory that the earth’s surface consists of plates in constant motion.D the theory that the earth’s surface was originally a plate-shaped heavenly body.79. One of the conclusions that we can reach from this passage is that ____A governmental interests always seem to clash with those of the private companies.B scientific findings are often obtained at the sacrifice of personal interests.C scientific truths are often rejected before they are widely accepted.D scientists are sometimes doubtful about their beliefs.80. The author seems to be suggesting that _______A the vested interests are sometimes on obstacle to the progress of science.B governments are the one to blame for the deterioration of the environment.C a timely response to people’s demand is appreciated by the academia.D the interference by the government resulted in the tragedy of the 1950s.Part V Translation (40 minutes, 20 points )The nations meeting here in Shanghai understand what is at stake. If we don’t stand against terrorism now, every civilized nation will at some point be its target. We will defeat the terrorists by destroying their network, wherever it is found.

The peoples of this region are more prosperous, healthier, and better educated than they were only two decades ago. And this progress has proved what openness can accomplish.Section B ( 20 minutes, 10 points )也许你觉得自己那些静卧于抽屉中的家书措辞不够优美,气息也不够现代,其实这正是我们所需要的,/毕竟时代的烙印和真挚的情怀是挥之不去,那亘古不变的魔力足以超出我们的想象。

Along with the prevalence of electronic devices, such as computers and cell phones, resulting from the development of high technology, in workplaces and schools, colleagues and classmates pour so much expectation into these devices to work out their projects that they tend to rely on emails to communicate with others instead of in person. While some people may claim that communication in person can be helpful to obtain everyone’s idea throu gh brainstorming, I am fully convinced that communicating through emails is more advisable in modern world. My reasons are listed as follows.Above all, it is more convenient to communicate via emails, which is better corresponding to working pace of modernists. Current employees usually confront more demanding schedules within the industry. As a result, they are often required do more jobs to meet needs, and quite commonly, working time and working locations differ from one to another. It seems more reasonable and considerate for all team members who are in the same target of a certain project to allow them to discuss or share ideas and processes through emails. By contrast, in light of the mentioned reason, it is difficult in some sense to make appointme nt members’ spare time and appropriate location before meeting. Insisting on meeting in personal to have discussion is time-consuming and priggish.Additionally, the records kept in the mailbox contribute a lot to the accomplishment of the project by avoiding possible subsequent controversies. The group meeting, namely so-called brainstorming, falls into chaos eventually in most cases, thus leading to heavy financial or reputational losses of the project because some individual group member might leave out some important information or arrangement due to confusion. What is worse, no one can be blamed in this case. However, such situation can totally be prevented by communication through emails. It is exceedingly easier to check respective assignment as well as the whole schedule of the project by the records of emails. In this way, some potential risks can be avoided, which is beneficial to the promotion of the project.Although there probably be some obvious advantages of face-to-face communication such as conveying more hidden information through facial expressions, tones or body language. However, “one thousand readers, one thousand Hamlet”, as Shakespeare says, everyone has his or her own way of thinking and understanding, so non-vocal expressions must misguide others in the group, which is seriously detrimental to the project. Rather than being regarded as a merit, the hidden additional information ought to be banned in serious working occasions out of the consideration of preciseness. Given this part, emails perform more prominently.According to the reasons discussed above, we can safely arrive at a conclusion that compared with discussing in person, communicating by emails will be much more advantageous.Nowadays, with the rapid development of high technology, quite a few of colleagues or classmates communicate with others through emails or telephones instead of face-to-face for doing a project. Nevertheless, I prefer communicate in person rather than emails or telephones as my inclination.Among countless factors which influence the choice, there are three conspicuous aspects as follows.The foremost reason for my agreement is that communicating in person is much more effective to advance a project.. It can be given a concrete example. When I was a college student, I was a member of a human behavior project. At first, our members of the project communicated with each other through email or telephones when we finished our observations. We typed amount of words to describe and explain what we learn ed from the latest experiment as well as read others’ emails and tried to understand their ideas. We wasted a lot of time because of reading and writing emails. Therefore, we decided to discuss to each other face to face. Then, we found that just through a n eye contact, we can distinguish other’s attitude; just using body language, we can express a complex meaning. Through this way, we boost our efficiency and strongly promote our project.When classmates or colleagues communicate about a certain project, it is better for them to work in person than by e-mail.Use specific reasons and examples to support your answer.The modern society has required an increasing number of cooperation to a great extent in order to guarantee the success of tasks individuals are supposed to accomplish either under circumstances of school life or in the situation of the working. During the process of that cooperation, excellent level of communication is demanded between each member working together. From my perspective, the way of exchanging ideas in person is more suitable to succeed in fulfilling a project than by email.It should be admitted that conveying opinions through emails could be considered to be wonderful from a certain viewpoint. That means of communication between members in a team can avoid the possible trouble they might encounter if they have to gather together in person including the traffic fare, the time of commuting, and the difficulty of finding time as well as location available for all of team members. However, the advantages of discussing the project in person outnumber those via emails involving both the quality and the efficiency of completing that discussion they need. Those benefits are regarded as significantly essential elements in achieving success of communication and accomplishing the assignments as well. Due to those merits, it is more beneficial for a group to talk with each other through face to face meetings than emails.Moreover, in terms of the quality of communication, a team working on a project is advised to choose to discuss topics in person rather than via emails. By chatting with each other about the task needed to be done in person, group members can realize the face to face communication,which is believed to be an effective method of avoiding probable misunderstandings during the discussion with involvements of facial expressions, eye contacts, and body gestures beside words, the combination of which could be more accurate than writing what the members want to describe in emails. Through sending emails, people have the possibility of delivering what they mean in a wrong way or even lacking the ability of portraying their meanings in the written form. For instance, a designing team in an advertisement firm is asked to create a visual advertisement on TV. Without meeting in person instead of exchanging thoughts by email, the person responsible for producing the video might not create the exact image the designing people desire due to the possibility that the video maker is misled by phrases in emails. Therefore, the communication through face to face talking is superior to the way of exchanging emails in the area of the accuracy of meanings.In addition, in order to promote the efficiency during communicating, it is more helpful to have face to face discussions than talking through emails. People need time to check and respond to their emails, and that time would be longer when some of them might be occupied by other errands or assignments, or coming across technical breakdown or errors of the Internet as well as the performance of email system. Even though those members are not disturbed by those unfortunate incidents, the interaction via emails demands more time for people to organize words to compose emails owing to the fact that usually it is the writing instead of speaking that consumes more time to complete. In contrast, having prepared themselves with a great deal of necessary materials, individuals can articulate their opinions and fully explain their standpoints in a relatively short time of discussing meeting. Besides, people can give their responses to the feedback, comments, or questions at the same meeting without delaying. Thus, the group would be more likely to obtain the satisfying arrangement and appropriate outcomes for the project they are dealing with just in one meeting.In conclusion, although presenting ideas through emails might possess favorable factors, communicating in person contributes to better quality of communication and high efficiency of working. Therefore, a team is encouraged to perform the discussion in person rather than by email.While we were taught from a young age that efficiency means multi-tasking, certain projects should be completed one at a time. Such practice ensures the quality of the final product and prevents from one having to redo certain parts of a long process. It also ensures the safety of those who will ultimately be the users of the final product.A person has a limited attention span, and a sole stress of efficiency often results in a compromise of quality. In projects that are highly detailed and require a lot of careful attention, a person must devote his full attention to the task in order to not make any careless mistakes. Take, for example, a biology project involving the genetic engineering of a human cell line. A lot of initial planning is involved in selecting the right cells suitable for growing in a laboratory and capable of modification. The cells must then be carefully monitored in a controlled environment to keep them alive. The genes to be altered are analyzed before there are delivered in a viral vector to the desired cells. All of steps toward achieving the final product are laboriously planned out and executed. Any small mishaps along the way can easily force the scientist to start the process all over again and waste months of previous work.Some projects are assigned with specific instructions for those involved to not take on any other projects. Such projects often involve products that will affect the safety of a large number of individuals. In the field of architectural design, a public structure to be used by thousands, even millions, of people every day will require that the initial project be carried out with care. The Tacoma Narrows Bridge was a public infrastructure completed in 1950 along the Puget Sound that was considered a monumental feat of engineering in its day. The twin suspension bridge, spanning 5,400 feet, took years of planning and construction by teams of architects, engineers, and construction workers. However, because the Department of Pacific Northwest Transportation was taking on several projects at the time and couldn’t simply focus on the bridge, the group of engineers failed to take the aerodynamics of the bridge into consideration during the design process. The gusts of wind along the Tacoma Narrows brought the structure to a collapse within months of the bridge’s opening, resulting in a catastrophe that is still rem embered to this day as a classic example of failure of engineering.As the two examples show, the projects of certain highly skilled professions require careful attention to detail and must be completed one at a time. Trying to couple several projects simultaneously will only result in one having to redo a lot of work due to careless errors or worse, a devastating loss of lives.。

But even though the Copernican theory greatly simplified the ptolemaic theory by eliminating the large epicycles(本轮) that were really the result of the earth’s own motion, neither the theory predicted the exact positions of the planets at all times.

科技英语阅读与写作题目:Harrington Time-HarmonicElectromagnetic Fields 学院:物理与光电工程学院专业:电子与通信工程学号:1405122310姓名:何超Partner姓名:张书彬学号:1403121555ABSTRACTThe uniqueness theorem of time-harmonic electromagnetic fields, which is the theoretical basis of boundary valueproblem (BVP) of electromagnetic fields, isreviewed. ○1So far there are many versions of the statements and proofs onthe theorem. However, there exist some limitations and lack of strictness in these versions, for instance, the discussionof the uniqueness of solution without considering the existence of solution and the lack of strictness in the case of losslessmedium. ○2In contrast with the traditional statements and proofs, this paper introduces some important conclusionson operator equation from modern theory of partial differential equation (PDE) and attempts to solve the problems onthe existence and uniqueness of the solution to operator equation which is derived from Maxwell’s equations oftime-harmonic electromagnetic fields. ○3This methoduniqueness of the solution to time- harmonic fields in the new mathematical framework. Some importantconclusions are presented.1. IntroductionIn the electromagnetics it has important significance toresearch time-harmonicelectromagnetic fields. ○4On one hand, most fields appeared in practical engineering problems have harmonic time variation and we can solve these engineering problems directly through researching time-harmonic fields. On the other hand, time-varying fields can be transformed into the superposition oftime-harmonic fields with the Fourier series or Fourier transform [1,2]. Therefore, a thorough understanding and discussion on the existence and uniqueness of the solution to time-harmonic electromagnetic fields are important in the study of all electromagnetic fields and electromagnetic wave phenomena.○5The necessity and importance of the uniqueness theorem consist in that if the appropriate initial-boundary value conditions of Maxwell’s equations are given, then the solution is determined uniquely.○6So regardless of the method by which the equations are solved, the same solution will be obtained. Recently, the issue on the uniqueness has aroused much concern [3-9]. ○7In this paper wepresents their proof method. ○8Secondly, we point out the limitations and lack ofIn the process of the traditional proof on Proposition 1, lossy medium is assumed. The field in a lossless medium is treated as the limit of the corresponding field in a lossy medium when the dissipation approaches to zero. In sense of mathematics this treatment is not rigorous because the validation in the case of a parameter approaching zero does not guarantee the validation in the case of the pa-rameter at the point of zero.The proofs on the uniqueness theorem in lossless medium appeared in many books and literatures such as [2] [14] are only an interpretation based on the assumption that the case in lossless medium has been validated. The discussion on uniqueness theorem in lossless medium is avoided in [15], which write “The proof of the theorem hinges on the assumption that the permittivity and the permeability of the medium have a small imaginary part. Assume the medium is slightly lossy.” Similarly, [18,19] have not made a definite conclusion and proof on the lossless case. Pozar in [20] considers that the solution for the lossless medium may be not unique unless the dissi-pation of medium is added. Hence, traditional theory has not given the proof of the uniqueness theorem in lossless medium strictly, which is a long-neglected problem. It is to be confirmed and proved whether there exists the uniqueness theorem in lossless medium.一.语言点○1So far there are many versions of the statements and proofs onthe theorem.○1So far.到目前为止 there be 句型○2In contrast with the traditional statements and proofs, this paper introduces some important conclusionson operator equation from modern theory of partial differential equation (PDE) and attempts to solve the problems onthe existence and uniqueness of the solution to operator equation which is derived from Maxwell’s equations oftime-harmonic electromagnetic fields.○2In contrast with 与....比较the method by which the equations are solved which引导定语从句 are solved 被动语态○7In this paper we mainly deal with the existence and uniqueness of the solutionfor time-harmonic electromagnetic fields.Firstly,this paper quotes some most influential versions of the uniqueness theorem of traditional time-harmonic electromagneticfields theory and presents their proof method.○7 deal with 应付;对待;处理○8Secondly, we point out the limitations and lack of strictness of traditional theoryand make a result that the traditional theory has not yet solved the existence anduniqueness of the solution completely.○8 point out 指出,表明 make a result that....同位语从句○9Moreover, we cite the proof of existence and uniqueness of the weaksolutionto 0-Dirichlet problem of the Poisson equation as an example to indicate that it is a rigorous method adoptingfunctional theory to discuss the existence and uniqueness of the solution to PDE.○9 cite as 引用an example to ...的一个例子indicate that 表明indicate that it is..... 宾语从句○10Finally, we introduce a novelconsideration of the operator equation based on the○10 based on 根据Derive...
