北京大学考博英语阅读理解习题29
北京大学考博英语阅读理解习题（29）A controversy erupted in the scientific community in early1998over the use of DNA （deoxyribonucleic acid）fingerprinting in criminal investigations.DNA fingerprinting was introduced in1987as a method to identify individuals based on a pattern seen in their DNA，the molecule of which genes are made.DNA is present in every cell of the body except red blood cells.DNA fingerprinting has been used successfully in various ways，such as to determine paternity where it is not clear who the father of a particular child is.However，it is in the area of criminal investigations that DNA fingerprinting has potentially powerful and controversial uses.DNA fingerprinting and other DNA analysis techniques have revolutionized criminal investigations by giving investigators powerful new tools in the attempt to trove guilt，not just establish innocence.When used in criminal investigations，a DNA fingerprint pattern from a suspect is compared with a DNA fingerprint pattern obtained from such material as hairs or blood found at the scene of a crime.A match between the two DNA samples can be used as evidence to convict a suspect.The controversy in1998stemmed form a report published in December1991by population geneticists Richard C.Lewontin of Harvard University in Cambridge，Mass.，and Daniel L. Hartl called into question the methods to calculate how likely it is that a match between two DNA fingerprints might occur by chance alone.In particular，they argued that the current method cannot properly determine the likelihood that two DNA samples will match because they came from the same individual rather than simply from two different individuals who are members of the same ethnic group.Lewontin and Hartl called for better surveys of DNA patterns methods are adequate.（PS:The way to contact yumingkaobo TEL:si ling ling-liu liu ba-liu jiu qi ba QQ:772678537) In response to their criticisms，population geneticists Ranajit Chakraborty of the University of Texas in Dallas and Kenneth K.Kidd of Yale University in New Haven，Conn.，argued that enough data are already available to show that the methods currently being used are adequate.In January1998，however，the federal Bureau of Investigation and laboratories that conduct DNA tests announced that they would collect additional DNA samples form various ethnic groups in an attempt to resolve some of these questions.And，in April，a National Academy of Sciences called for strict standards and system of accreditation for DNA testing laboratories.1.Before DNA fingerprinting is used，suspects____.A.would have to leave their fingerprints for further investigationsB.would have to submit evidence for their innocenceC.could easily escape conviction of guiltD.cold be convicted of guilt as well2.DNA fingerprinting can be unreliable when____.A.the methods used for blood-cell calculation are not accurateB.two different individuals of the same ethnic group may have the same DNA fingerprinting patternC.a match is by chance left with fingerprints that happen to belong to two different individualsD.two different individuals leave two DNA samples.3.To geneticists like Lewontin and Hartl，the current method____.A.is not so convincing as to exclude the likelihood that two DNA samples can never come from two individualsB.is arguable because two individuals of the same ethnic group are likely to have the same DNA pattern.C.Is not based on adequate scientific theory of geneticsD.Is theoretically contradictory to what they have been studying4.The attitude of the Federal Bereau of Investigation shows that____.A.enough data are yet to be collected form various ethnic groups to confirm the unlikelihood of two DNA samples coming from two individual membersB.enough data of DNA samples should be collected to confirm that only DNA samples form the same person can matchC.enough data are yet to be collected from various ethnic groups to determine the likelihood of two different DNA samples coming form the same personD.additional samples from various ethnic groups should be collected to determine that two DNA samples are unlikely to come from the same person5.National Academy of Sciences holds the stance that____.A.DNA testing should be systematizedB.Only authorized laboratories can conduct DNA testingC.The academy only is authorized to work out standards for testingD.The academy has the right to accredit laboratories for DNA testing答案：ＣＢＡＢＢ本文由“育明考博”整理编辑。

Read the passages carefully and choose the best answer to each question. Put your answer on the ANSWER SHEET. (10%)Passage OneWhat Makes a “Millennial Mind”?Since 1000 AD, around 30 billion people have been born on our planet. The vast majority have come and gone unknown to all but their friends and family. A few have left some trace on history: a discovery made, perhaps, or a record broken. Of those, fewer still are remembered long after their death. Yet of all the people who have lived their lives during the last 1, 000 years, just 38 have achieved the status of “Millennial Minds” -that's barely one in a billion. Those whose lives Focus has chronicled have thus become members of possibly the most exclusive list of all time. And choosing who should be included was not easy.From the beginning, the single most important criterion was that the “Millennial Minds” are those who did more than merely achieve greatness in their own time, or in one field. Thus mere winners of Nobel Prizes had no automatic right to inclusion, nor artists who gained fame in their own era, but whose reputation has faded with changing fashion. The achievements of the genuine “Millennial Mind” affect our lives even now, often in ways so fundamental that it is hard to imagine what the world was like before.Not even transcendent genius was enough to guarantee a place in the Focus list. To rate as a “Millennial Mind”, the life and achievements also had to cast light on the complex nature of creativity: its origins, nature, and its personal cost.61. The first paragraph tells us that__________.A. Focus had a list of “Millennial Minds” worked out in secretB. Focus had compiled a biographical book of the lives of “Millennial Minds”C. Focus's list of the “Millennial Minds” consists of a strictly selected fewD. Focus tried hard to exclude most of the famous lives from the list of the “Millennial Minds”62. According to the second paragraph, which of the following statements is TRUE?A. Nobel Prize winners are not qualified for the “Millennial Minds”.B. A “Millennial Mind” needs only to have a great influence on the lives of the people of his time.C. Only those whose achievements still greatly affect our lives today can be included in the list of the “Millennial Minds”.D. The “Millennial Minds” are those who have changed human lives so much that people of later generations can not remember what things were likein the past.63. In the first sentence of the third paragraph, “transcendent genius” means__________.A. people who are exceptionally superior and great in talentB. people whose achievements are not forgotten by later generationsC. people whose genius has been passed down to the present timeD. people who have guaranteed themselves a place in the Focus list64. In the third paragraph, t he phrase “cast light on” can be replaced by__________.A. shine overB. light upC. shed light onD. brighten upPassage TwoTribute to Dr. Carlo Urbani, Identifier of SARSOn the 29th of March, 2003, the World Health Organization doctor Carol Urbani died of Severe Acute Respiratory Syndrome, the fast-spreading pneumonia that had killed 54 people worldwide.http:The 46-year-old Italian doctor was the first WHO officer to identify the outbreak of this new disease in an American businessman. Dr. Urbani first saw the US businessman on Feb. 28, two days after the patient had been admitted to a hospital in Hanoi. Although Urbani had worn a mask, he lacked goggles and other protective clothing. He began demanding that Hanoi hospitals stock up on protective gear and tighten up infection control procedures. But he was frustrated at how long it was taking to teach infection-control procedures to people in hospitals. There were shortages of supplies, like disposable masks, gowns, gloves.After three weeks of round-the-clock effort, Urbani's superior urged him to take a few days off to attend a medical meeting in Bangkok, where he was to talk on childhood parasites. The day after he arrived, he began feeling ill-with symptoms of the new disease. He called his wife, now living in Hanoi with their three children. He said:“Go back to Italy and take the children, because this will be the end for me.” Dr. Urbani developed a fever and was put into isolation where he remained until his death. The WHO representative in Hanoi said:“He was very much a doctor, his first goal was to help people.”He was buried on April 2, 2003 in Castelplanio, central Italy, leaving behind his wife and children. The measures he helped put in place before his death appear to have doused the SARS wildfire in Vietnam.65. Which of the following statements is NOT TRUE?A. Dr. Urbani caught SARS from an American businessman who was hospitalized in Hanoi.B. There were not enough disposable masks, gowns, gloves and protective equipment.C. He knew he had little hope to survive after he was found infected.D. Dr. Urbani had helped combating the new disease by putting in place a series of infection-control measures.66. In the third paragraph, “three weeks of round-clock effort”means__________.A. for three weeks the hospital was taking in SARS patients without stoppingB. Dr Urbani worked day and night for three weeks, trying to get SARS under controlC. for three weeks Dr. Urbani did not have any time to sleep, trying hard to fight the new diseaseD. After three weeks hard work to control SARS, the hospital superior thought it was time to stop the clock67. According to the context, the word “doused” in the last sentence of this passage could be best replaced with__________.A. extinguishedB. eliminatedC. solvedD. delugedPassage ThreeGlassSince the Bronze Age, about 3000 B. C., glass has been used for making various kinds of objects. It was first made from a mixture of silica, lime, and an alkali such as soda or potash, and these remained the basic ingredients of glass until the development of lead glass in the seventeenth century.When heated the mixture becomes soft and moldable and can be formed by various techniques into a vast array of shapes and sizes. The homogeneous mass thus formed by melting then cools to create glass, but in contrast to most materials formed in this way (metals, for instance), glass lacks the crystalline structure normally associated with solids, and instead retains the random molecular structure of a liquid. In effect, as molten glass cools, it progressively stiffens until rigid, but does so without setting up a network of interlocking crystals customarily associated with that process. This is why glass shatters so easily when dealt a blow.Another unusual feature of glass is the manner in which its viscosity changes as it turns from a cold substance into a hot, ductile liquid. Unlike metals that flow or “freeze” at specific temperatures, glass progressively softens as the temperature rises, going through varying moldable stages until it flows like a thick syrup. Each of these stages allows the glass to be manipulated into various forms, by different techniques, and if suddenly cooled the object retains the shape achieved at that point. Glass is thus open to a greater number of heat-forming techniques than most other materials.68. According to the passage glass cools and becomes rigid differently from metalsbecause__________.A. it has an unusually low melting temperatrueB. it does not set up a network of interlocking crystalsC. it has a random molecular structure of a liquidD. it is made from a mixture of silica, lime, and soda69. In the phrase “without setting up a network of interlocking crystals customarily associated with that process” in the second paragraph, a substitute for the word “customarily” may be__________.A. continuouslyB. certainlyC. eventuallyD. usually70. Glass can be easily molded into all kinds of forms because__________.A. it melts like liquid when heatedB. it softens gradually through varying stages when heatedC. it retains the shape at the point when it is suddenly cooledD. various heating techniques can be used in making glassⅡ. Directions: Read the following passage carefully and then explain in your own English the exact meaning of the numbered and underlined parts. Put your answers on the ANSWER SHEET. (15%)No one gets out of this world alive, and few people come through life without at least one serious illness. (71) If we are given a serious diagnosis, it is useful to try to remain free of panic and depression. Panic can constrict blood vessels and impose an additional burden on the heart.(72) Depression, as medical researchers way back to Galen, an ancient Greek doctor, have observed, can set the stage for other illnesses or intensify existing ones. It is no surprise that so many patients who learn that they have cancer or heart disease-or any other catastrophic disease-becomeworse at the time of diagnosis. (73) The moment they have a label to attach to their symptoms, the illness deepens. All the terrible things they have heard about disease produce the kind of despair that in turn complicates the underlying condition. (74) It is not unnatural to be severely apprehensive about a serious diagnosis, but a reasonable confidence is justified. Cancer today, for example, is largely a treatable disease. A heavily damaged heart can be reconditioned. (75) Even a positive HIV diagnosis does not necessarily mean that the illness will move into the active stage.Part Four Cloze TestDirections: Fill in each numbered blank in the following passage with ONE suitable word to complete the passage. Put your answers on the ANSWER SHEET. (10%)Flowers for the DeadSince flowers symbolize new life, it may seem inappropriate to have them at funerals. Yet people in many cultures top coffins or caskets with wreaths and garlands and put blossoms on the graves of the (76) __________. This custom is part of a widespread, long-lived pattern. Edwin Daniel Wolff speculated that floral tributes to the dead are an outgrowth of the grave goods of ancient (77)__________. In cultures that firmly believed in an (78)__________, and believed further that thedeparted could enter that afterlife only (79) __________they took with them indications of their worldly status, it was a necessity to bury the dead with material goods: hence the wives and animals that were killed to accompany (80)__________rulers, the riches (81)__________with Egyptian pharaohs, and the coins that Europeans used to place on the departed person's eyes as payment for the Stygian ferryman. In time, as economy modified tradition, the actual (82)__________goods were replaced (83)__________symbolic representations. In China, for example, gold and silver paper became a stand-in (84)__________real money. Eventually even the symbolic significance became obscured. Thus, Wolff said, flowers may be the (85)__________step in “three well-marked stages of offerings to the dead: the actual object, its substitute in various forms, and —finally —me re tributes of respect.”Part Five ProofreadingDirections: This part consists of a short passage. In this passage, there are altogether 10 mistakes, one in each underlined sentence or part of a sentence. You may have to change a word, add a word or just delete a word. If you change a word, cross it out with a slash (\) and write the correct word near it. If you add a word, write the missing word between the words (in brackets) immediately before and after it. If you delete a word, cross it out with a slash (\). Put your answers on the ANSWER SHEET.

(87) In this way, consumers and business may find easier to make cheaper telephone calls under new rules that the Federal Communications Commission began preparing on Thursday. (88) Taking together, the new rules could profoundly affect the architecture of the Internet and the services it provides. (89) They also have enormous implications for consumers, the telephone and energy industries, equipment manufacturers. Michael K. Powell, the F. C. C. chairman, and his two Republican colleagues on the five-member commission said that (90) a 4-to-1 vote on Thursday to allow a small company providing computer-to-computer phone connections to operate in different rules from ordinary phone companies, would ultimately transform the telecommunications industry and the Internet.(91) “This is a reflecting of the commission's commitment to bring tomorrow's technology to consumers today,” said Mr. Powell. He added that (92)the rules governing the new phone services sought to make them as wide available as e-mail, (93) and possibly much less expensive than traditional phones, and given their lower regulatory costs. At the same time, (94) once while the rules allowing delivery of the Internet through power lines are completed, (95) companies could provide consumers with the ability to plug their modems directly into wall sockets, just like they do with a toaster, or a desk lamp.Part Six WritingDirections: Write a short composition of about 250 to 300 words on the topic given below.

Why didn't we recognize this until our life has been endangered? Surely, epidemic diseases as a kind of public health crises, have contributed to people's perception of public health crises.Public health itself is not new, but the term ”public health crises “has been fresh for most people in China. It includes not only outbreaks of diseases, but also water erosion, deforestation, desertification and many other problems which mankind as a whole must face. Ever since the industrial revolution and great economic expansion, people's life has been challenged in one way or another due to lots of irresponsible behaviors of mankind. Most of the time, people have accustomed to their ordinary way of life and do not spare time in comprehending the imminent crises.On the other hand, epidemic outbreaks always take on a very severe outlook and thus pose direct dangers to common people. They affect people's daily activities and even their lives, and that is why they can successfully arouse people's concerns about their own health. To some extent, our awareness of our dining habits and carelessness in protecting the environment can be attributed to the outbreak of some epidemics, like SARS and bird flu.We should all be gratitude for this awareness brought about by some epidemics. As China and the world's economy continue to expand, governments and people are fully aware that some measures have to be taken to fend off any possible danger to public health.A. is to send them to clinicsB. offers recapture of earlier experiencesC. is in the provision of clockwork toys and trainsD. is to capture them before they are sufficiently experienced47. The child in the nursery__________.A. quickly learns to wait for foodB. doesn't initially sleep and wake at regular intervalsC. always accepts the rhythm of the world around themD. always feels the world around him is warm and friendly48. The encouragement of children to achieve new skills__________.A. can never be taken too farB. should be left to school teachersC. will always assist their developmentD. should be balanced between two extremes49. Jigsaw puzzles are__________.A. too difficult for childrenB. a kind of building-block toyC. not very entertaining for adultsD. suitable exercises for parent-child cooperation50. Parental controls and discipline__________.A. serve a dual purposeB. should be avoided as much as possibleC. reflect the values of the communityD. are designed to promote the child's happinessQuestions 51 to 55 are based on the following passage:More than half of all Jews married in U. S. since 1990 have wed people who aren't Jewish. Nearly 480, 000 Americanhildren under the age of ten have one Jewish and one non-Jewish parent. And, if a survey compiled by researchers at the University of California at Los Angeles is any indication, it's almost certain that most of these children will not identify themselves as “Jewish” when they get older.That survey asked college freshmen, who are usually around age 18, about their own and their parents' religious identities. Ninety-three percent of those with two Jewish parents said they thought of themselves as Jewish. But when the father wasn't Jewish, the number dropped to 38 percent, and when the mother wasn't Jew, just 15 percent of the students said they were Jewish, too.“I think what was surprising was just how low the Jewish identification was in these mixed marriage families.” Linda Sax is a professor of education at UCLA. She directed the survey which was conducted over the course of more than a decade and wasn't actually about religious identity specifically. But Professor Sax says the answers to questions about religion were particularly striking, and deserve a more detailed study. She says it's obvious that interfaith marriage works against the development of Jewish identity among children, but says it's not clear at this point why that's the case. “This new study is necessary to get more in-depth about their feelings about their religion. That's something that the study that I completed was not able to do. We didn't have information on how they feel about their religion, whether they have any concern about their issues of identification, how comfortable they feel about their lifelong goals. I think the new study's going to cover some of that,” she says.Jay Rubin is executive director of Hilel, a national organization that works with Jewish college students. Mr. Rubin says Judaism is more than a religion, it's an experience. And with that in mind, Hillel has commissioned a study of Jewish attitudes towards Judaism. Researchers will concentrate primarily on young adults, and those with two Jewish parents, and those with just one, those who see themselves as Jewish and those who do not. Jay Rubin says Hillel will then use this study to formulate a strategy for making Judaism more relevant to the next generation of American Jews.51. The best title of this passage is__________.A. Jewish and Non-Jewish in AmericanB. Jewish Identity in AmericaC. Judaism-a Religion?D. College Jewish Students52. Among the freshmen at UCLA__________thought themselves as Jewish.A. mostB. 93% of those whose parents were both JewishC. 62% of those only whose father were JewishD. 15% of those only whose mother were Jewish53. The ph rase “interfaith marriage” in the Paragraph 3 refers to the__________.A. marriage of people based on mutual beliefB. marriage of people for the common faithC. marriage of people of different religious faithsD. marriage of people who have faith in each other54. Which of the following statements is NOT true about professor Sax's research?A. The research indicates that most students with only one Jewish parent will not think themselves as Jewish.B. The survey was carried out among Jewish Freshmen.C. The research survey didn't find out what and how these Jewish students think about their religion.D. The research presents a new perspective for the future study.55. Which of the following is true according to the last paragraph?A. Mr. Rubin is the founder of Hillel.B. Mr. Rubin thinks that Judaism is not a religion and it's an experience.C. Hillel is an organization concerned with Jewish college students in the world.D. Hillel has asked certain people to carry out a study about Jewish attitudes towards Judaism.Questions 56 to 60 are based on the following passage:Governments that want their people to prosper in the burgeoning world economy should guarantee two basic rights: the right to private property and the right to enforceable contracts, says Mancur Olson in his book Power and Prosperity. Olson was an economics professor at the University of Maryland until his death in 1998.Some have argued that such rights are merely luxuries that wealthy societies bestow, but Olson turns that argument around and asserts that such rights are essential to creating wealth. “In comes are low in most of the countries of the world, in short, because the people in those countries do not have secure in dividual rights,” he says.Certain simple economic activities, such as food gathering and making handicrafts, rely mostly on individual labor; property is not necessary. But more advanced activities, such as the massproduction of goods, require machines and factories and offices. This production is often called capital-intensive, but it is really property-intensive, Olson observes.“No one would normally engage in capital-intensive production if he or she did not have rights that kept the valuable capital from being taken by bandits, whether roving or stationary,”he argues. “There is no private property without government—individuals may have possessions, the way a dog possesses a bone, but there is private property only if the society protects and defends a private right to that possession against other private parties and against the government as well.”Would-be entrepreneurs, no matter how small, also need a government and court system that will make sure people honor their contracts. In fact, the banking systems relied on by developed nations are based on just such an enforceable contract system. “We would not deposit our money in banks...if we could not rely on the bank having to honor its contract with us, and the bank would not be able to make the profits it needs to stay in business if it could not enforce its loan contracts with borrowers,” Olson writes.Other economists have argued that the poor economies of Third World and communist countries are the result of governments setting both prices and the quantities of goods produced rather than letting a free market determine them. Olson agrees there is some merit to this point of view, but he argues that government intervention is not enough to explain the poverty of these countries. Rather, the real problem is lack of individual rights that give people incentive to generate wealth. “If a society has clear and secure individual rights, there are strong incentives (刺激，动力）to produce, invest, and engage in mutually advantageous trade, and therefore at least some economic advance,” Olson conc ludes.56. Which of the following is true about Olson?A. He was a fiction writer.B. He edited the book Power and Prosperity.C. He taught economics at the University of Maryland.D. He was against the ownership of private property.57. Which of the following represents Olson's point or view?A. Protecting individual property rights encourages wealth building.B. Only in wealthy societies do people have secure individual rights.C. Secure individual rights are brought about by the wealth of the society.D. In some countries, people don't have secure individual rights because they're poor.58. What does Olson think about mass production?A. It's capital intensive.B. It's property intensive.C. It relies on individual labor.D. It relies on individual skills.59. What is the basis for the banking system?。

Mark your answers on the Answer Sheet.2009 was the worst year for the record labels in a decade31 was 2008, and before that 2007 and 2006. In fact, industry revenues have been 32 for the past 10 years. Digital sales are growing, but not as fast as traditional sales are falling.Maybe that’s because illegal downloads are so easy. People have been 33 intellectual property for centuries, but it used to be a time-consuming way to generate markedly 34 copies. These days, high-quality copies are 35 . According to the Pew Internet project, people use file-sharing software more often than they do iTunes and other legal shops.I’d like to believe, as many of my friends seem to, that this practice won’t do much harm. But even as I’ve heard over the past decade that things weren’t 36 bad, that the music industry was moving to a new, better business model, each year’s numbers have been worse. Maybe it’s time to admit that we may never find a way to 37 consumers who want free entertainment with creators who want to get paid.38 on this problem, the computational neuroscientist Anders Sandberg recently noted that although we have strong instinctive feelings about ownership, intellectual property doesn’t always 39 that framework. The harm done by individual acts of piracy is too small and too abstract.“The nature of intellectual property,”he wrote, “makes it hard to maintain the social and empathic 40 that keep(s) us from taking each other’s things.”31.

For each question or unfinished statement, four answers are given. Read the passages carefully and choose the best answer to each question. Mark your choices on the Answer Sheet.Passage OneCancer has always been with us, but not always in the same way. Its care and management have differed over time, of course, but so, too, have its identity, visibility, and meanings. Pick up the thread of history at its most distant end and you have cancer the crab—so named either because of the ramifying venous processes spreading out from a tumor or because its pain is like the pinch of a crab’s claw. Premodern cancer is a lump, a swelling that sometimes breaks through the skin in ulcerations producing foul-smelling discharges. The ancient Egyptians knew about many tumors that had a bad outcome, and the Greeks made a distinction between benign tumors (oncos) and malignant ones (carcinos). In the second century A．D．, Galen reckoned that the cause was systemic, an excess of melancholy or black bile, one of the body’s four “humors,”brought on by bad diet and environmental circumstances. Ancient medical practitioners sometimes cut tumors out, but the prognosis was known to be grim. Describing tumors of the breast, an Egyptian papyrus from about 1600 B．C．concluded: “There is no treatment.”The experience of cancer has always been terrible, but, until modern times, its mark on the culture has been light. In the past, fear coagulated around other ways of dying: infectious and epidemic diseases (plague, smallpox, cholera, typhus, typhoid fever); “apoplexies”(what we now call strokes and heart attacks); and, most notably in the nineteenth century, “consumption”(tuberculosis). The agonizing manner of cancer death was dreaded, but that fear was not centrally situated in the public mind—as it now is. This is one reason that the medical historian Roy Porter wrote that cancer is “the modern disease par excellence,”and that Mukherjee calls it “the quintessential product of modernity.”At one time, it was thought that cancer was a “disease of civilization,” belonging to much the same causal domain as “neurasthenia” and diabetes, the former a nervous weakness belie ved to be brought about by the stress of modern life and the latter a condition produced by bad diet and indolence. In the eighteenth and nineteenth centuries, some physicians attributed cancer—notably of the breast and the ovaries—to psychological and behavioral causes. William Buchan’s wildly popular eighteenth-century text “Domestic Medicine”judged that cancers might be caused by “excessive fear, grief, religious melancholy.”In the nineteenth century, reference was repeatedly made to a “cancer personality,”and, in some versions, specifically to sexual repression. As Susan Sontag observed, cancer was considered shameful, not to be mentioned, even obscene. Among the Romantics and the Victorians, suffering and dying from tuberculosis might be considered a badge of refinement; cancer death was nothing of the sort. “It seems unimaginable,”Sontag wrote, “to aestheticize”cancer.41. According to the passage, the ancient Egyptians .A. called cancer the crabB. were able to distinguish benign tumors and malignant onesC. found out the cause of cancerD. knew about a lot of malignant tumors42. Which of the following statements about the cancers of the past is best supported by the passage?A. Ancient people did not live long enough to become prone to cancerB. In the past, people did not fear cancerC. Cancer death might be considered a badge of refinementD. Some physicians believed that one s own behavioral mode could lead to cancer43. Which of the following is the reason for cancer to be called “the modern disease”?A. Modern cancer care is very effectiveB. There is a lot more cancer nowC. People understand cancer in radically new ways nowD. There is a sharp increase in mortality in modern cancer world44.“Neurasthenia”and diabetes are mentioned because .A. they are as fatal as cancerB. they were considered to be “disease of civilization”C. people dread them very muchD.they are brought by the high pressure of modern life45. As suggested by the passage, with which of the following statements would the author most likely agree?A. The care and management of cancer have development over timeB. The cultural significance of cancer shifts in different timesC. Cancer s identity has never changedD. Cancer is the price paid for modern lifePassage TwoIf you happened to be watching NBC on the first Sunday morning in August last summer, you would have seen something curious. There, on the set of Meet the Press, the host, David Gregory, was interviewing a guest who made a forceful case that the U．S．economy had become “very distorted.”In the wake of the recession, this guest explained, high-income individuals, large banks, and major corporations had experienced a “significant recovery”; the rest of the economy, by contrast—including small businesses and “a very significant amount of the labor force”—was stuck and still struggling. What we were seeing, he argued, was not a single economy at all, but rather “fundamentally two separate types of economy,”increasingly distinct and divergent.This diagnosis, though alarming, was hardly unique: drawing attention to the divide between the wealthy and everyone else has long been standard fare on the left. (The idea of “two Americas”was a central theme of John Edwards’s 2004 and 2008 presidential runs.) What made the argument striking in this instance was that it was being offered by none other than the former five-term Federal Reserve Chairman Alan Greenspan: iconic libertarian, preeminent defender of the free market, and (at least until recently) the nation’s foremost devotee of Ayn Rand. When the high priest of capitalism himself is declaring the growth in economic inequality a national crisis, something has gone very, very wrong.This widening gap between the rich and non-rich has been evident for years. In a 2005 report to investors, for instance, three analysts at Citigroup advised that “the World is dividing into two blocs—the Plutonomy and the rest”.In a plutonomy there is no such animal as “the U．S．consumer”or “the UK consumer”, or indeed “the Russian consumer”. There are rich consumers, few in number, but disproportionate in the gigantic slice of income and consumption they take. There are the rest, the “non-rich”, the multitudinous many, but only accounting for surprisingly small bites of the national pie.Before the recession, it was relatively easy to ignore this concentration of wealth among an elite few. The wondrous inventions of the modern economy—Google, Amazon, the iPhone broadly improved the lives of middle-class consumers, even as they made a tiny subset of entrepreneurs hugely wealthy. And the less-wondrous inventions—particularly the explosion of subprime credit—helped mask the rise of income inequality for many of those whose earnings were stagnant.But the financial crisis and its long, dismal aftermath have changed all that. A multi-billion-dollar bailout and Wall Street’s swift, subsequent reinstatement of gargantuan bonuses have inspired a narrative of parasitic bankers and other elites rigging the game for their own benefit. And this, in turn, has led to wider-and not unreasonable-fears that we are living in not merely a plutonomy, but a plutocracy, in which the rich display outsize political influence, narrowly self interested motives, and a casual indifference to anyone outside their own rarefied economic bubble.46. According to the passage, the U．S．economy .A. fares quite wellB. has completely recovered from the economic recessionC. has its own problemsD. is lagging behind other industrial economies47. Which of the following statement about today’s super-elite would the passage support?A. Today’s plutocrats are the hereditary eliteB. Today’s super-rich are increasingly a nation unto themselvesC. They are the deserving winners of a tough economic competitionD. They are worried about the social and political consequences of rising income inequality48. What can be said of modern technological innovations?A. They have lifted many people into the middle class.B. They have narrowed the gap between the rich and the non-rich.C. They have led to a rise of income inequality.D. They have benefited the general public.49. The author seems to suggest that the financial crisis and its aftermath .A. have compromised the rich with the non-richB. have enriched the plutocratic eliteC. have put Americans on the alert for too much power the rich possessD. have enlarged the gap between the rich and non-rich50. The primary purpose of the passage is to .A. present the financial imbalance in the U．S．B. display sympathy for the working classC. criticize the super elite of the Unite StatesD. appreciate the merits of the super rich in the U．S．Passage ThreeCharles Darwin’s “On the Origin of Species”is credited with sparking evolution’s revolution in scientific thought, but many observers had pondered evolution before him. It was understanding the idea’s significance and selling it to the public that made Darwin great, according to the Arnold Arboretum’s new director.William Friedman, the Arnold Professor of Organism and Evolutionary Biology who took over as arboretum director Ja n．1, has studied Darwin’s writings as well as those of his predecessors and contemporaries. While Darwin is widely credited as the father of evolution, Friedman said the “historical sketch”that Darwin attached to later printings of his masterpiece was intended to mollify those who demanded credit for their own earlier ideas.The historical sketch grew with each subsequent printing, Friedman told an audience Monday (Ja n．10), until, by the 6th edition, 34 authors were mentioned in it. Scholars now believe that somewhere between 50 and 60 authors had beaten Darwin in their writings about evolution Included was Darwin’s grandfather, Erasmus Darwin, a physician who irritated clergymen with his insistence that life arose from lower forms, specifically mollusks.Friedman’s talk, “A Darwinian Look at Darwin’s Evolutionist Ancestors,”took place at the arboretum’s Hunnewell Building and was the first in a new Director’s Lecture Series.Though others had clearly pondered evolution before Darwin, he wasn’t without originality. Friedman said that Darwin’s thinking on natural selection as the mechanism of evolution was shared by few, most prominently Alfred Wallace, whose writing on the subject after years in the field spurred Darwin’s writing of “On the Origin of Species.”Although the book runs more than 400 pages, Friedman said it was never the book on evolution and natural selection that Darwin intended. In 1856, three years before the book was published, he began work on a detailed tome on natural selection that wouldn’t see publication until 1975.The seminal event in creating “On the Origin of Species”occurred in 1858, when Wallace wrote Darwin detailing Wallace’s ideas of evolution by natural selection. The arrival of Wallace’s ideas galvanized Darwin into writing “On the Origin of Species”as an “abstract”of the ideas he was painstakingly laying out in the larger work.This was a lucky break for Darwin, because it forced him to write his ideas in plain language, which led to a book that was not only revolutionary, despite those who’d tread similar ground before, but that was also very readable.Though others thought about evolution before Darwin, scientific discovery requires more than just an idea. In addition to the concept, discovery requires the understanding of the significance of the idea, something some of the earlier authors clearly did not have—such as the arborist who buried his thoughts on natural selection in the appendix of a book on naval timber. Lastly, scientific discovery demands the ability to convince others of the correctness of an idea. Darwin, through “On the Origin of Species,”was the only thinker of the time who had all three of those traits, Friedman said.“Darwin had the ability to convince others of the correctness of the idea,” Friedman said, adding that even Wallace, whose claim to new thinking on evolution and natural selection was stronger than all the others, paid homage to Darwin by titling his 1889 book on the subject, “Darwinism.”51. According to William Friedman, Darwin’s “On the Origin of Species”is great in that.A. it was the most studied by later scientistsB. it had significant ideas about evolutionC. it was the first to talk about evolutionD. it was well received by the public52. Friedman believes that Darwin attached a “historical sketch”to later printings of his book in an attempt to .A. credit the ideas about evolution before hisB. claim himself as the father of evolutionC. introduce his grandfather to the readerD. summarize his predecessors work53. In Friedman s view, Darwin s originality lies in .A. his thinking on natural selection as the mechanism of evolutionB. his sharing ideas about evolution with his contemporariesC. the way he wrote “On the Origin of Species”D. the way he lectured on the ideas of evolution54. We have learned that at first Darwin intended to write his idea in .A. a much larger bookB. a 400page bookC. scientific termsD. plain language55. Scientific discovery requires all the following Expect .A. coming up with a new ideaB. understanding the significance of the ideaC. making claims to the idea by writing booksD. convincing others of the correctness of the idesPassage FourMany adults may think they are getting enough shut-eye, but in a major sleep study almost 80 percent of respondents admitted to not getting their prescribed amount of nightly rest. So, what exactly is the right amount of sleep? Research shows that adults need an average of seven to nine hours of sleep a night for optimal functionality. Read on to see just how much of an impact moderate sleep deprivation can have on your mind and body.By getting less than six hours of sleep a night, you could be putting yourself at risk of high blood pressure. When you sleep, your heart gets a break and is able to slow down for a significant period of time. But cutting back on sleep means your heart has to work overtime without its allotted break. In constantly doing so, your body must accommodate to its new conditions and elevate your overall daily blood pressure. And the heart isn’t the only organ that is overtaxed by a lack of sleeps. The less sleep you get, the less time the brain has to regulate stress hormones, and over time, sleep deprivation could permanently hinder the brain’s ability to regulate these hormones, leading to elevated blood pressure.We all hang around in bed during our bouts of illness. But did you know that skipping out on the bed rest can increase your risk of getting sick? Prolonged sleep deprivation has long been associated with diminished immune functions, but researchers have also found a direct correlation between “modest”sleep deprivation—less than six hours—and reduced immune response. So try to toughen up your immune system by getting at least seven hours of sleep a night, and maintaining a healthy diet. You’ll be glad you got that extra hour of sleep the next time that bug comes around and leaves everyone else bedridden with a fever for three days.During deep REM sleep, your muscles (except those in the eyes) are essentially immobilized in order to keep you from acting out on your dreams. Unfortunately, this effort your body makes to keep you safe while dreaming can sometimes backfire,resulting in sleep paralysis. Sleep paralysis occurs when the brain is aroused from its REM cycle, but the body remains in its immobilizing state. This can be quite a frightening sensation because, while your mind is slowly regaining consciousness, it has no control over your body, leaving some with a feeling of powerlessness, fear and panic. Most people experience this eerie phenomena at least once in their lives, but those who are sleep deprived are more likely to have panicked episodes of sleep paralysis that are usually accompanied by hallucinations, as well.For a second, imagine all of your memories are erased; every birthday, summer vacation, even what you did yesterday afternoon is completely lost, because you have no recollection of them. It’s a chilling thought, but that is what a life without sleep would be like. Sleep is essential to the cognitive functions of the brain, and without it, our ability to consolidate memories, learn daily tasks, and make decisions is impaired by a large degree. Research has revealed that REM sleep, or dream-sleep, helps solidify the “fragile”memories the brain creates throughout the day to that they can be easily organized and stored in the mind’s long-term cache.56. According to the passage, what is the meaning of “sleep deprivation”?A. To sleep for an average period of time.B. To sleep deeply without dreaming.C. To sleep less than needed.D. To sleep modestly.57. Which of the following statements is TRUE according to Paragraph 3?A. When everyone else gets a fever, those with sleep deprivation will be abele to sleep longer.B. When everyone else gets a fever, those who usually have adequate sleep will be alright.C. Only modest sleep deprivation could weaken the immune system.D. Prolonged sleep deprivation will not have impact on the immune system.58. Why is there the so-called “sleep paralysis”?A. It occurs when you are unable to wake up from dreams while you are sleeping.B. It occurs when you brain immobilizes your body in order to keep you from dreaming.C. Because you are usually too frightened to move your body when waking up from deep REM sleep.D. Because your body, immobilized when dreaming, may still be unable to move even when your brain is waking up.59.Which of the following statements is TRUE according to the last paragraph?A. Memories are part of the cognitive function of the brain.B. Memories created during the daytime are usually fragile and impaired.C. You are likely to lose your memories of yesterday after a night’s sleep.D. Long term memory cannot be formed without dream-sleep.60. What effects of sleep deprivation on human mind and body are discussed in this passage?A. High blood pressure, a toughened immune system, sleep paralysis, and memory loss.B. Blood pressure, immune system, sleep paralysis, and long term memory.C. Blood pressure, immune system, the brain and the body, and memory.D. High blood pressure, a weakened immune system, sleep paralysis, and memory loss.Part V: Proofreading (15%)Directions: In the following passage, there are altogether 15 mistakes, ONE in each numbered and underlined part.

(68) They will send a text message or e-mail alerting them when the order is ready, which usually takes about four hours.(69) “Not only we see it as a nice convenience for customers, but we also saw it as a way to drive incremental traffic to the stores, and incremental sales,”said Steve Nave, senior vice president and general manager of Walmar t．Com.(70) The program will include about 40000 items likewise electronics, toys, home décor and sporting goods. (71) As of now, it does not include groceries, though M r．Nave did dismiss that possibility.(72) “We’re not ready to talk today about everything that’s going on in grocery,”he said“What we’ve tried to do is (73) focus on those categories where customers are most likely to be willing to make the purchase after they touch it or look at it.(74) This is a convenient play, trying to figure out what are the things that are going to drive more customers into the stores.”Wal-Mart also announced that (75) it was shortened the time customers would have to wait for ship-to-store items, to four to seven days, from seven to 10 days.Part VI: Writing (15%)Directions: Read the following paragraph and then write a response paper of about 250 to 300 words.

Although he was able to hold a conversation in nine languages, he was most comfortable in German. Every morning, before going to his office, he read the German language newspaper, which was American owned and published in New York.My grandfather was the only one in his family to come to the United States with his wife and children. He still had relatives living in Europe. When the first world war broke out, he lamented the fact that if my uncle, his only son had to go, it would be cousin fighting against cousin. In the early days of the war, my grandmother begged him to stop taking the German newspaper and to take an English language newspaper, instead. He scoffed at the idea, explaining that the fact it was in German did not make it a German newspaper, but only an American newspaper, printed in German. But my grandmother insisted, for fear that the neighbors may see him read it and think he was German. So, he finally gave up the German newspaper.One day, the inevitable happened and my uncle Milton received notice to join the army. My grandparents were very upset, but my mother, his little sister, was excited. Now she could boast about her soldier brother going off to war. She was ten years old at the time, and my uncle, realizing how he was regarded by his little sister and her friends, went out and bought them all service pins, which meant that they had a loved one in the service. All the little girls were delighted. When the day came for him to leave, his whole regiment, in their uniforms, left together from the same train station. There was a band playing and my mother and her friends came to see him off. Each one wore her service pin and waved a small American flag, cheering the boys, as they left.The moment came and the soldiers, all very young, none of whom had had any training, but who had never the less all been issued uniforms, boarded the train. The band played and the crowd cheered. The train groaned as if it knew the destiny to which it was taking its passengers, but it soon began to move. Still cheering and waving their flags, the band still playing, the train slowly departed the station.It had gone about a thousand yards when it suddenly ground to a halt. The band stopped playing, the crowd stopped cheering. Everyone gazed in wonder as the train slowly backed up and returned to the station. It seemed an eternity until the doors opened and the men started to file out. Someone shouted, “It’s the armistice. The war is over.” For a moment, nobody moved, but then the people heard someone bark orders at the soldiers. The men lined up and formed into two lines. They walked down the steps and, with the band playing behind, paraded down the street, as returning heroes, to be welcomed home by the assembled crowd. The next day my uncle returned to his job, and my grandfather resumed reading the German newspaper, which he read until the day he died.41. Where was the narrator’s family when this story took place?A. In Germany.B. In Hungary.C. In the United StatesD. In New York.42.His grandfather ____________.A. could not speak and read English well enoughB. knew nine languages equally wellC. knew a number of languages, but felt more kin to GermanD. loved German best because it made him think of home43. His grandmother did not want her husband to buy and read newspapers in German, because ________.A. it was war time and Germans were their enemyB. the neighbors would mistake them as pro-GermanC. it was easier to get newspapers in English in AmericaD. nobody else read newspapers in German during the wartime44. The narrator’s mother wanted her brother to go to fight in the war,because________.A. like everybody else at the wartime, she was very patrioticB. she hated the war and the Germans very muchC. all her friends had relatives in war and she wanted to be like themD. she liked to have a brother she could think of as a heroPassage TwoWaking Up from the American DreamsThere has been much talk recently about the phenomenon of “Wal-Martization” of America, which refers to the attempt of America’s giant Wal-Mart chain store company to keep its cost at rock-bottom levels. For years, many American companies have embraced Wal-Mart-like stratagems to control labor costs, such as hiring temps (temporary workers) and part-timers, fighting unions, dismantling internal career ladders and outsourcing to lower paying contractors at home and abroad.While these tactics have the admirable outcome of holding down consumer prices, they’re costly in other ways. More than a quarter of the labor force, about 34 million workers, is trapped in low-wage, often dead-end jobs. Many middle-income andhigh-skilled employees face fewer opportunities, too, as companies shift work to subcontract or sand temps agencies and move white-collar jobs to China and India. The result has been an erosion of one of America’s most cherished value: giving its people the ability to move up the economic ladder over their life times. Historically, most Americans, even low-skilled ones, were able to find poorly paid janitorial or factory jobs, then gradually climbed into the middleclass as they gained experience and moved up the wage curve. But the number of workers progressing upward began to slip in 1970s. Upward mobility diminished even more in the 1980s as globalization and technology slammed blue-collar wages.Restoring American mobility is less a question of knowing what to do than of making it happen. Experts have decried schools’ in adequacy for years, but fixing them is a long, arduous struggle. Similarly, there have been plenty of warnings about declining college access, but finding funds was difficult even in eras of large surpluses.45. The American dream in this passage mainly refers to____________.A. there are always possibilities offered to people to develop themselves in the societyB. Americans can always move up the pay ladderC. American young people can have access to college, even they are poorD. the labor force is not trapped in low-wage and dead-end jobs46. Wal-Mart strategy, according to this passage, is to___________.A. hire temps and part-timers to reduce its costB. outsource its contracts to lower price agencies at home and abroadC. hold down its consumer price by controlling its labor costsD. dismantle the career ladder and stop people’s mobility upward47. Which of the following statements is NOTTRUE?A. Wal-Martization has been successful in keeping costs at rock-bottom levels.B. Upward mobility for low-skilled workers has become impossible in the U.S.C. More business opportunities are given to low-cost agencies in China and India.D. Although people know how to restore American mobility, it’s difficult to change the present situation.Passage Three Seniors and the CityTens of thousands of retirees are pulling up stakes in suburban areas and fashioning their own retirement communities in the heart of the bustling city. They are looking for what most older people want: a home with no stairs and low crime rates. And they are willing to exchange regular weekly golf time for rich cultural offerings, young neighbors and plenty of good restaurants. Spying an opportunity, major real-estate developer shave broken ground on urban sites they intended to market to suburbanretirees. These seniors are already changing the face of big cities. One developer, Fran Mc Carthy asks: “Who ever thought that suburban flight would be roundtrip?”The trickle of older folks returning to the city has grown into a steady stream. While some cities, especially those with few cultural offerings, have seen an exodus of seniors, urban planners say others have become retirees magnets. Between 1999 and 2000, the population of 64-to-75-year-olds in downtown Chicago rose 17 percent. Austin, New Orleans, and Los Angeles have seen double-digit increases as well. There may be hidden health benefits to city living. A study reveals that moving from suburbs to the city can ward off the byproduct of aging--- social isolation. In the next six years, downtowns are expected to grow even grayer. For affluent retirees, city life is an increasingly popular option.48. Retired seniors are moving back into the city because____________.A. they find there are too many crimes in the suburbsB. unlike the flats in the city, their country house have stairs to climbC. they are no longer interested in playing golfD. in the city, they have more social and cultural life against loneliness49. From the passage we can infer that_________.A. the real-estate developers have broken their original contracts of construction with senior retireesB. a life in the downtown city is expensive, and most of those retirees who moved back into the city are very well-offC. with more older people living in the city, the city will become gray and less beautifulD. very soon the American suburban areas will face their low population crisis50. Fran Mc Carthy’s question means: nobody ever thought that__________.A. people who moved out of the city decades ago now would move backB. suburban dwellers when moving back into the city must take roundtripC. suburban flight years ago would go in circlesD. senior people’s moving back into the city would take place all over the United StatesDirections: Read the following passage carefully and then explain in your own English the exact meaning of the numbered and underlined parts. Put your answers on ANSWERSHEET(2)15(51) Being angry increases the risk of injury, especially among men, new research says. There searchers gathered data on more than 2,400 accident victims at three Missouri hospitals. They interviewed each subject to determine the patient’s emotional state just before the injury and 24 hours earlier, gathering data on whether the patients felt irritable, angry or hostile, and to what degree. Then they compared the results with a control group of uninjured people.(52)Despite widespread belief in “road rage,” anger did not correlate with injuries from traffic accidents.(53)Not surprisingly, anger was strongly associated with injuries inflicted deliberately. But other injuries– those neither intentionally inflicted nor from falls or traffic accidents– also showed strong associations with anger.(54)The correlations were significantly weaker for women than for men, but there were no differences by race. The authors acknowledge that their data depend on self-reports, which are not always reliable.(55)Why anger correlates with injury is not known. “I can speculate that the anger may have prompted some behavior that led to the injury, or may have simply distracted the person, leading indirectly to the injury,” said the study’s lead author.Part Four: Cloze Test10Directions: Read the following passage carefully and then fill in each numbered blank with ONE suitable word to complete the passage.

For each question four answers are given. Read the passages carefully and choose the best answer to each question. Mark your choices on the ANSWER SHEET. (10%)Passage OneIn science the meaning of the word “explain” suffers with civilization’s every step in search of reality. Science cannot really explain electricity, magnetism, and gravitation; their effects can be measured and predicted, but of their nature no more is known to the modern scientist than to Thales who first speculated on the electrification of amber. Most contemporary physicists reject the notion that man can ever discover what these mysterious forces “really” are. Electricity, Bertrand Russell says, “is not a thing, like St. Paul’s Cathedral; it is a way in which things behave. When we have told how things behave when they are electrified, and under what circumstances they are electrified, we have told all there is to tell.” Until recently scientists would have disapproved of such an idea. Aristotle, for example, whose natural science dominated Western thought for two thousand years, believed that man could arrive at an understanding of reality by reasoning from self-evident principles. He felt, for example, that it is a self-evident principle that everything in the universe has its proper place, hence one can deduce that objects fall to the ground because that’s where they belong, and smoke goes up because that’s where it belongs. The goal of Aristotelian science was to explain why things happen. Modern science was born when Galileo began trying to explain how things happen and thus originated the method of controlled experiment which now forms the basis of scientific investigation.41. Bertrand Russell’s notion about electricity is __________.[A] disapproved of by most modern scientists[B] in agreement with Aristotle’s theory of self-evident principles[C] in ag reement with scientific investigation directed toward “how” things happen[D] in agreement with scientific investigation directed toward “why” things happen42. The passage says that until recently scientists disagreed with the idea that __________.[A] there are self-evident principles[C] man cannot discover what forces “really” are [B] there are mysterious forces in the universe [D] we can discover why things behave as they do43. The expression “speculated on” (line 4) means __________ .[A] considered [B] suspected [C] expected [D] engaged in buying and sellingPassage TwoThe concept of personal choice in relation to health behaviors is an important one. An estimated 90 percent of all illnesses may be preventable if individuals would make sound personal health choices based upon current medical knowledge. We all enjoy our freedom of choice and do not like to see it restricted when it is within the legal and moral boundaries of society. The structure of American society allows us to make almost all our own personal decisions that may concern our health. If we so desire, we can smoke, drink excessively, refuse to wear seat belts, eat whatever foods we want, and live a completely sedentary life-style without any exercise. The freedom to make such personal decisions is a fundamental aspect of our society, although the wisdom of these decisions can be questioned. Personal choices relative to health often cause a difficulty. As one example, a teenager may know the facts relative to smoking cigarettes and health but may be pressured by friends into believing it is the socially accepted thing to do. A multitude of factors, both inherited and environmental, influence the development of health-related behaviors, and it is beyond the scope of this text to discuss all these factors as they may affect any given individual. However, the decision to adopt a particular health-related behavior is usually one of personal choice. There are healthy choices and there are unhealthy choices. In discussing the morals of personal choice, Fries and Crapo draw a comparison. They suggest that to knowingly give oneself over to a behavior that has a statistical probability of shortening life is similar to attempting suicide. Thus, for those individuals who are interested in preserving both the quality and quantity of life, personal health choices should reflect those behaviors that are associated with a statistical probability of increased vitality and longevity.44. The concept of personal choice concerning health is important because __________.[A] it is essential to personal freedom in American society[B] it helps raise the level of our medical knowledge[C] personal health choices help cure most illnesses[D] wrong decisions could lead to poor health45. Sound personal health choice is often difficult to make because __________.[A] current medical knowledge is still insufficient[B] there are many factors influencing our decisions[C] people are usually influenced by the behavior of their friends[D] few people are willing to trade the quality of life for the quantity of life46. According to Fries and Crapo, sound health choice should be based on __________.[A] personal decisions [B] society’s laws[C]friends’ opinions[D] statistical evidencePassage ThreeFor gathering data about individuals or groups at different developmental levels, researchers can use two related research designs: longitudinal and cross-sectional.A longitudinal study is one that measures a behavior or a characteristic of an individual over a period of time, perhaps decades. An example of such a study is the Berkeley Growth Study begun in 1928 by Nancy Bayley. The study focused on a group of 74 white, middle-class newborns. As they grew older, extensive measures of their intellectual, personality, and motor development were recorded. The subjects were studied for more than thirty years.The longitudinal research design is a powerful technique for seeking understandings of the effects of early experiences on later development. Also, differences in or stability of behaviors or characteristics at different ages can be determined. Longitudinal studies, however, are expensive to conduct, time-consuming, and heavily contingent on the patience and persistence of the researchers. The findings of a longitudinal study may be jeopardized by relocation of subjects to another part of the country and by boredom or irritation at repeated testing. Another disadvantage is that society changes from one time to another and the subjects participating in the study reflect to some degree such changes. The methods of study or the questions guiding the researchers may alsochange from one time to another. If properly conducted, however, longitudinal studies can produce useful, direct information about development.A cross-sectional study is one in which subjects of differing ages are selected and compared on a specific behavior or characteristic. They are alike with respect to socioeconomic status, sex, or educational level. For example, a researcher may be interested in looking at changes in intelligence over a thirty-year period. Three groups of subjects, ages ten, twenty, and thirty, may be selected and tested. Conclusions are drawn from the test data.The cross-sectional research design has the clear advantage of being less expensive to conduct and certainly less time-consuming. The major disadvantage is that different individuals who make up the study sample have not been observed over time. No information about past influences on development or about age-related changes is secured. Like longitudinal studies, the cross-sectional methods cannot erase the generational influence that exists when subjects studied are born at different time. Psychologists are now beginning to use an approach that combines longitudinal and cross-sectional research methods.47. Which of the following is NOT one of the disadvantages of a longitudinal research?[A] The subjects may become irritated at repeated testing.[B] The participants in the study may not stay in one place for many years.[C] The behavior of a subject in the study may be measured continuously for many years.[D] Social changes may be reflected in the behaviors of the subjects participating in the study.48. The word “contingent” in the third paragraph probably means __________.[A] dependent [B] consecutive [C] determined [D] continual49. Which of the following statements is true?[A] The subjects in a cross-sectional research are not of the same age group.[B] The methods of study in longitudinal research will not change over time.[C] Longitudinal research is reliable only in seeking understandings of the effects of early experiences on later development.[D] Cross-sectional methods are not usually adopted in studying, for example, the changes in intelligence over a thirty-year period.50.One of the differences between cross-sectional research and longitudinal research is that __________.[A] the latter usually focuses on only one subject, while the former involves groups of subjects[B] the former can be free from the influence of social changes[C] the latter can be free from the influence of social changes[D] the former costs less money and takes less timeSection BDirections: Read the following passage carefully and then explain in your own English the exact meaning of the numbered and underlined parts. Put your answers on ANSWER SHEET (2). (15%)(51) It is useful to remember that history is to the nation as memory is to the individual. As persons deprived of memory become disoriented and lost, not knowing where they have been and where they are going, so a nation denied a conception of the past will be disabled in dealing with its present and its future. History is the best antidote to delusions of omnipotence and omniscience.(52) Self-knowledge is the indispensable prelude to self-control, for the nation as well as for the individual. History should forever remind us of the limits of our passing perspectives. It should strengthen us to resist the pressure to convert momentary impulses into moral absolutes. It should lead us to recognition of the fact, so often and so sadly displayed, that the future outwits all our certitudes and that the possibilities of the future are more various than the human intellect is designed to conceive.(53) A nation informed by a vivid understanding of the ironies of history is best equipped to manage the tragic temptations of military power. Let us not bully our way through life, but let a sensitivity to history temper andcivilize our use of power. In the meantime, let a thousand historical flowers bloom.(54) History is never a closed book or a final verdict. It is forever in the interests of an ideology, a religion, a race, and a nation. The great strength of history is its capacity for self-correction. This is the endless excitement of historical writing: the search to reconstruct what went before.(55) A nation’s history must be both the guide and the domain not so much of its historians as its citizens.Part IV: Cloze Test (10%)Directions: Read the following passage carefully and then fill in each numbered blank with ONE suitable word to complete the passage.

(67) There were increases across the board, but for usual it was the already wealthy who fared best. (68) Stanford's $911 million was the most ever collected by a single university, and rose the possibility of a billion-dollar fund-raising year in the not-too-distant future. (69) "There were a set of ideas and a set of initiatives that the university is undertaking that people wanted to invest," said Martin Shell, Stanford's vice president for development. (70) "This is an unbelievably generous response from unbelievably philanthropic set of alumni, parents, and friends." (71) Harvard ranked two in fund-raising last year with $595 million. (72) National, donations from alumni rose 18.3 percent from 2005, according to figures released yesterday by the Council for Aid to Education. (73) Alumni donations account about 30 percent of giving to higher education. (74) Giving from other groups, such as corporations and foundations, increased by much small amounts. (75) Survey director Ann Kaplan said the strong economics played a role, but universities also were asking more aggressively as part of formal fund-raising campaigns.Part VI: Writing (15%)Directions: Read the following paragraph and then write a response paper of about 250 to 300 words.

For each question four answers are given. Read the passages carefully and choose the best answer to each question. Put your choice in the ANSWER SHEET. (10%)Passage One(1) Gerald Feinberg, the Columbia University physicist, once went so far as to declare that "everything possible will eventually be accomplished." Well, that of course left only the impossible as the one thing remaining for daring intellectual adventurers to whittle away at Feinberg, for one, thought that "they'd succeed even there."(2) It was a point worth considering. How many times in the past had certain things been said to be impossible, only to have it turn out shortly thereafter that the item in question had already been done or soon would be. What greater cliche was there in the history of science than the comic litany of false it-couldn't-be-dones; the infamous case of Auguste Comte saying in 1844 that it would never be known what the stars were made of, followed in a few years by the spectroscope being applied to starlight to reveal the stars' chemical composition; or the case of Lord Rutherford, the man who discovered the structure of the atom, saying in 1933 mat dreams of controllednuclear fission were "moonshine." And those weren't even the worst examples. No, the huffiest of all it-couldn't-be-done claims centered on the notion that human beings could actually fly, either at all, or across long distances, or to the moon, the stars, or wherever else.(3) There had been so many embarrassments of this type that about mid-century Arthur C. Clarke came out with a guideline for avoiding them, which he termed Clarke's Law: "When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong."(4) Still, one had to admit there were lots of things left that were really and truly impossible, even if it took some ingenuity in coming up with a proper list of examples. Such as. "A camel cannot pass through the eye of a needle." (Well, unless of course it was a very large needle.) On "It is impossible for a door to be simultaneously open and closed." (Well, unless of course it was a revolving door.)(5) Indeed, watertight examples of the really and truly impossible were so exceptionally hard to come by that paradigm cases turned out to be either trivial or absurd. "I know I will never play the piano like Vladimir Horowitz," offered Milton Rothman, a physicist, "no matter how hard I try". Or, from Scott Lankford, a mountaineer "Everest on roller skates."21. The false it-couldn't-be-dones in science are comic because ______.A. they are cliches, repeated too often by scientistsB. they are almost always proved to be wrong by later scientific researchC. they are mocked at by later generationsD. they provide material for good comedies22. Which of the following statements is TRUE?A. The author uses the case of a camel passing through the eye of a needle to prove his point that there are things impossible to accomplish.B. That a scientist cannot play the piano like one of the best pianists is not a proper illustration to prove that in science there are things impossible to accomplish.C. Scott Lankford challenges the idea that mountaineers can never climb the Everest on roller skates.D. People now laugh at their predecessors for denying the possibility of human flight.23. Through this passage, the author wants to ______.A. show us that scientists in the past years have made a lot of misjudgmentsB. praise those scientists who dared to challenge the impossibleC. emphasize the great potential of the scientific research made by human beingsD. analyze what is possible and what is impossible through scientific effortsPassage Two(1) Since the lineage of investigative journalism is most directly traceable to the progressive era of the early 1900's, it is not surprising that the President of the United States at the time was among the first to articulate its political dimensions. Theodore Roosevelt called investigative reporters "muckrakers," after a character from John Bunyan's Pilgrim's Progress who humbly cleaned "the filth off the floor." Despite the misgivings implied by the comparison, Roosevelt saw the muckrakers as "often indispensable to the well-being of society".(2) There are in the body politic, economic and social, many and grave evils, and there is urgent necessity for the sternest war upon them. There should be relentless exposure of and attack upon every evil man, whether politician or businessman.(3) Roosevelt recognized the value-laden character of investigative journalism. He perceived correctly that investigative reporters are committed to unearthing wrongdoing. For these journalists, disclosures of morally outrageous conduct maximize the opportunity for the forces of "good" to recognize and do battle with the forces of "evil".(4) So, the current folklore surrounding investigative reporting closely resembles the American ideal of popular democracy. Partly a product of its muckraking roots, this idealized perspective is also an outgrowth of the commonly perceived effects of exposes published in the early 1970's. The most celebrated of these exposes were the news stories that linked top White House officials to Watergate crimes. These stories were widely held responsible for the public's loss of confidence in the Nixon administration, ultimately forcing the President's resignation. 24. When the author talks about the political dimensions of the investigative journalism he refers to ______.A. John Bunyan's Pilgrim's Progress and one of its characters "Muckrakers"B. its function of cleaning the dirt off the floor in public placesC. its relentless exposures of political and social evilsD. its indispensable status to the well-being of society25. Roosevelt's comparison of investigative reporters to "muckrakers" shows his view that these reporters ______.A. were treated lowly in the societyB. reduced journalism to a humble jobC. should be praised highly for their contributions to the societyD. did unpleasant but necessary work26. By using the word "folklore", the author suggests that ______.A. people tend to romanticize what is thought to be American popular democracyB. investigative journalism enhances democracy and freedomC. people often circulate the stories they read from investigative reportsD. investigative reports have difficulty in convincing people as truth27. The Watergate incident is mentioned to show ______.A. journalism has a tangible effect on politicsB. the Watergate incident is an abuse of the political powerC. journalism subverts legitimate political powerD. the victory of American freedom of speechPassage Three(1) Viewed from a star in some other corner of the galaxy, Earth would be a speck, a faint blue dot hidden in the blazing light of our sun. While our neighbors Venus and Mars would reflect a fairly even glow. Earth would put on a little show. Earth's light would brighten and dim as it spins, because oceans, deserts, forests and clouds which are all too small to be seen from such a distance, reflect varying amounts of sunlight. The variations, it turns out, are so strong and distinctive that surprising amount of information could be taken from a simple ebb and flow of light. Scientists at Princeton University and the Institute for Advanced Study conducted a detailed study of Earth's reflections as a way for human scientists to learn about distant planets that may be like our own.(2) "If you looked at our solar system from far away, and you looked at the terrestrial planets Mercury, Venus, Earth and Mars, one of the quickest ways to see that Earth is unique, which is bylooking at the light curve," said Ed Turner, professor of astrophysics and a co-author of the study. "Earth has by far the most complicated light curve." The standard thinking in the field had been that most of the information about an Earth-like planet would come from spectral analysis, a static reading of the relative component of different colors within the light, rather than a reading of changes over time. Spectral analysis would reveal the presence of gases such as water vapor, carbon dioxide and oxygen, in the planet's atmosphere. Looking at the change in light over time does not replace spectral analysis, but it could greatly increase the amount of information scientists could learn, said Turner. It may indicate, for example, the presence of weather, oceans, ice or even plant life.28. "Earth would put on a little show" means: as it spins, ______.A. Earth is a more active planet than Venus and MarsB. Earth reflects a brighter light curve than Venus and MarsC. Earth shows oceans, deserts, forests and clouds, while Venus and Mars don'tD. Earth reflects sunlight in an ebb-and-flow manner29. Spectral reading of the light reflected by an Earth-like planet ______.A. can tell us the components of that planet's atmosphereB. can locate oceans and forests on that planetC. can show what the weather on that planet is likeD. is the quickest way to study its light curve30. Which of the following statements is TRUE?A. Scientists at the Princeton University want to find that distant planets are like our Earth.B. Among all the terrestrial planets Earth's light curve is the most complicated.C. Spectral study of the light will see no development of itself because it is static.D. Spectral reading is used as a supplementary method to the study of the change in light over time.Section BDirections: Read the following passage carefully and then explain in your own English the exact meaning of the numbered and underlined parts. Put your answers in the ANSWER SHEET. (15%)(31) A couple of months ago, Singaporean officials unintentionally made cinematic history. They slapped an NC-17 rating on a film, which means children under 17 cannot see it, not because of sex or violence or profanity, but because of bad grammar. Despite its apparently naughty title. Talking Cock, the movie is actually an innocuous comedy comprising four skits about the lives of ordinary Singaporeans. The censors also banned a 15-second TV spot promoting the flick. (32) All this is because of what the authorities deemed "excessive use of Singlish."(33) Given the tough crackdown, you would expect Singlish to be a harmful substance that might corrupt our youth, like heroin or pornography. But it's one of Singapore's best-loved quirks, used daily by everyone from cabbies to CEOs. (34) Singlish is simply Singaporean slang, whereby English follows Chinese grammar and is liberally sprinkled with words from the local Chinese. Malay and Indian dialects.I like to talk cock, and I like to speak Singlish. It's inventive, witty and colorful. (35) Singlish is especially fashionable these days among the younger generation, in part because it gives uptight Singapore a chance to laugh at itself. But the government is not amused. It doesn't like Singlish because it thinks it is bad language and bad for Singapore's image as a commercial and financialcenter.Part Three Cloze TestDirections:Fill in each numbered blank in the following passage with ONE suitable word to complete the passage.

Reading ComprehensionReading ComprehensionWe’ve all heard about whalewatching from boats or shore, and a few companies are now offering the possibility of actually swimming and snorkeling with whales in the wild. Is this a good thing? Some whalewatching operators in the Kingdom of Tonga, South Pacific islands, advertise the possibility of swimming and snorkeling with humpback whales during the cetacean’s annual migration from July to October. This activity sounds appealing, yet there are a number of things to consider. To drop clients off within snorkeling distance of a whale, the swim boats must come closer than the 30 meters laid down in Tongan government guidelines in 1997. Engine noise from a maneuvering boat can startle a whale, and repeated disturbances can lead to the animals changing their behaviour and even abandoning their traditional habitat. The nursing and resting routines of the pods can be disrupted, potentially threatening the health of the whales. This high-risk activity is not covered by most travel insurance policies. The humpback whales of Tonga are wild animals with powerful fins, and swimming near one always involves some risk. The movements of these huge creatures can be fatal to a human swimmer, either accidentally or if the beast feels threatened, and a nursing mother with calf can be especially unpredictable. Swimming into the path of a whale greatly increases the danger. In Tonga, sharks are known to frequent areas where there are whales, especially calves, and at least one shark attack on a Tongan guide swimming with whales has been recorded. A tragic accident involving tourists seems to be only a matter of time. Most whale encounters occur in deep waters where unperceived currents and wave action can soon tire a snorkeler and possibly lead to panic. For these reasons, responsible whalewatching companies like http://www. whalediscoveries. com do not offer snorkeling with whales. Of course, the demand is there, and pressure has come to bear on the Tongan Government to revise its guidelines to allow boats to come within 10 meters of a whale. Several new whalewatching licenses have been issued recently, raising the number of commercial operators in this small area to about a dozen, and vessels often have to queue to drop off swimmers. Cases have been observed of boats approaching to within five meters of whale pods, and of mother humpbacks and calves being pursued out to sea. Visitors should be aware that by purchasing such an excursion, they could be adversely affecting the noble creatures they came to see. It’s a good idea to discuss these matters with the operator before booking your trip, and to avoid those who seem most interested in maximizing their own profits at the expense of the whales. Even if you decide to book such a tour, be aware that only 10 percent of swim with attempts are successful and there are no refunds. These concerns only apply to attempts to actually swim with whales, and whalewatching from a boat at a safe distance is no problem.
