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?。

3.名词解释(1) 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. (2) Selfknowledge is the indispensable prelude to self-control, for the nation as well as for 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.(3) 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 and civilize our use of power. In the meantime, let a thousand historical flowers bloom. (4) 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. (5) A nation's history must be both the guide and the domain not so much of its historians as its citizens.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【答案】1.History is to a nation what memory is to a person, so keep it in mind is helpful.2.Self-knowledge is an essential premise for self-control of the nation and individual.3.If a nation can learn a lot from its history lessons, it is well prepared for controlling the impulsion of resorting to force.4.History is not constant and invariable.5.The history of a nation is the director and researching field of its citizens rather than its historians.4.单选题Going through a tricky divorce would be enough to put anyone off marriage for life.

WritingReading ComprehensionSecurity and commodity exchanges are trading posts where people meet who wish to buy and sell. The exchanges themselves do no trading,they merely provide a place where prospective buyers and sellers can meet and conduct their business. Wall Street,although the best known,is not home of exchanges in the United States. There are the cotton exchanges in New Orleans and Chicago; the Mercantile Exchange which deals in many farm products in Chicago; and grain exchanges in many of the large cities of the Midwest. Some exchanges,like Chicago Board of Trade,provide market services for several kinds of products. These trading posts where products may be brought or sold are called commodity exchanges. The security exchanges,on the other hand,are meeting places where stocks and bonds are traded. Like the commodity exchanges,they help serve the economic life of the country. But when their operations get out of hand,they may become very dangerous. In 1929,the security exchange,or stock market,contributed to a crash-a sudden sharp decline in the value of securities. Many people lost fortunes; many corporations were bankrupted; many workers lost their jobs. The crash of 1929 has been attributed to many causes,among them wild and unwise speculation by many people and dishonest practices on the part of some business and of some members of the exchanges. Today,however,investing through security exchanges and trading on commodity exchanges has been made safer by regulations set up by the exchanges themselves and by regulations of the United States government. In 1922,the government instituted the Commodity Exchange Commission which operates through the Department of agriculture; and in 1934,the Securities Exchange Commission,to protect investors and the public against dishonest practices on the exchanges.1．Security and commodity exchanges are meeting places for buyers and sellers of_____.A．stocksB．securitiesC．productsD．all of the above正确答案：D解析：本题的四个选项中，只有D项为正确答案。

WritingReading ComprehensionBird wings have a much more complex job to do than the wings of an airplane, for in addition to supporting the bird they must act as its engine, rowing it through the air. Even so the wing outline or a bird conforms to the same aerodynamic principles as those eventually discovered by people when designing airplanes, and if you know how different kinds of aircraft perform, you can predict the flight capabilities of similarly shaped birds. Short, stubby wings enable a tanager and other forest-living to swerve and dodge at speed through the undergrowth, just as they helped the fighter planes of the Second World War to make tight turns and acrobatic maneuvers in a dog-fight. More modern fighters achieve greater speeds by sweeping back their wings while in flight, just as peregrines do when they go into a 130kph dive, swooping to a kill. Championship gliders have long, thin wings so that, having gained height in a thermal up-current they can soar gently down for hours and an albatross, the largest of flying birds, with a similar wing shape and a span of 3 meters, can patrol the ocean for hours in the same way without a single wing beat. Vultures and hawks circle at very slow speeds supported by a thermal and they have the broad rectangular wings that very slow-flying aircraft have. People have not been able to adapt wings to provide hovering flight. That has only been achieved with the whirling, horizontal blades of a helicopter or the downward-pointing engines of a vertical landing jet. Hummingbirds have paralleled even this. They tilt their bodies so that they are almost upright and then beat their wings as fast as 80 times a second producing a similar downdraft of air. So the hummingbird can hover and even fly backwards.1．Which of the following is NOT true according to the passage?A．Bird wings have to support the bird.B．Bird wings must act as the bird’s engine.C．Airplane’s wings must act as the airplane’s engine.D．Similar wing shapes in aircraft and birds produce similar flight capabilities.正确答案：C解析：题目问：根据文章内容，哪项不是真实的?第一段“Bird wings have a much more complex job to do than the wings of an airplane，for in addition to supporting the bird they must act as its engine，rowing it through the air．”通过这句话可知，与飞机的机翼相比，鸟的翅膀的功能更复杂，它能支持鸟体，还是鸟飞翔的引擎。

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.

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. You may have to change a word, add a word, or just delete a word. If you change a word, cross it with a slash (/) and write the correct word beside 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 answer on the Answer Sheet (2).Examples:eg. 1(61) The meeting begun 2 hours ago.Correction put on the Answer Sheet (2): (61) begun beganeg. 2(62) Scarcely they settled themselves in their seats in the theatre when the curtain went up .Correction put on the Answer Sheet (2): (62) (Scarcely) had (they)eg. 3(63) Never will I not do it again.Correction put on the Answer Sheet (2): (63)notWal-Mart announced Thursday afternoon that it would introduce a program nationwide called (61) “Pick Up Today”that allows customers to submit orders online and pick up their items few hours later in their local store. (62) The move is not revolutionary—Sears and Nordstrom, as instance, already have similar programs.(63) Retailers say that tying online and in-store inventory together lets them to sell more products. (64) Nordstrom recently combined its inventory so that if the online stockroom is out of a jacket, a store that has it can ship to the Web customer. (65) Encourage customers to retrieve items they have ordered online in a store increases visits to the stores, which usually increases sales. (66) Best Buy offers both store pickup and “ship to store,”where items are shipped free from a local store. Ace Hardware, J．C．Penney and Wal-Mart itself are among the others offering “ship to store”programs.In Wal-Mart’s program, (67) that is expected to be nationwide by June, customers can select from among 40,000 items online. (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.
