Each passage is followed by some questions or unfinished statements. For each of them there are four choicesmarked A), B), C) and D). You should decide on the best choice and markthe corresponding letter on the Answer Sheet with a single line through thecentre.Passage OneQuestions 21 to 25 are based on the following passage.There are good reasons to be troubled by the violence that spreads throughout the media. Movies, Television and video games are full of gunplay and bloodshed, and one might reasonably ask what‟s wrong with a society that presents videos of domestic violence as entertainment.Most researchers agree that the causes of real-world violence are complex. A 1993 study by the U.S. National Academy of Sciences listed “biological, individual, family, peer, school, and community factors” as all playing their parts.Viewing abnormally large amounts of violent television and video games may well contribute to violent behavior in certain individuals. The trouble comes when researchers downplay uncertainties in their studies or overstate the case for causality (因果关系). Skeptics were dismayed several years ago when a group of societies including the American Medical Association tried to end the debate by issuing a joint statement: “At this time, well over 1,000 studies... point overwhelmingly to a causal connection between media violence and aggressive behavior in some children.”Freedom-of-speech advocates accused the societies of catering to politicians, and even disputed the number of studies (most were review articles and essays, they said). When Jonathan Freedman, a social psychologist at the University of Toronto, reviewed the literature, he found only 200 or so studies of television-watching and aggression. And when he weeded out “the most doubtful measures of aggression”, only 28% supported a connection.The critical point here is causality. The alarmists say they have proved that violent media cause aggression. But the assumptions behind their observations need to be examined. When labeling games as violent or non-violent, should a hero eating a ghost really be counted as a violent event? And when experimenters record the time it takes game players to read …aggressive‟ or …non-aggressive‟ words from a list, can we be sure what they are actually measuring? The intent of the new Harvard Center on Media and Child Health to collect and standardize studies of media violence in order to compare their methodologies, assumptions and conclusions is an important step in the right direction.Another appropriate step would be to tone down the criticism until we know more. Several researchers write, speak and testify quite a lot on the threat posed by violence in the media. That is, of course, their privilege. But when doing so, they often come out with statements that the matter has now been settled, drawing criticism from colleagues. In response, the alarmists accuse critics and news reporters of being deceived by the entertainment industry. Such clashes help neither science nor society.21. Why is there so much violence shown in movies, TV and video games?A) There is a lot of violence in the real world today.B) Something has gone wrong with today‟s society.C) Many people are fond of gunplay and bloodshed.D) Showing violence is thought to be entertaining.22. What is the skeptics (Line 3. Para. 3) view of media violence?A) Violence on television is a fairly accurate reflection of real-world life.B) Most studies exaggerate the effect of media violence on the viewers.C) A causal relationship exists between media and real-world violence.D) The influence of media violence on children has been underestimated.23. The author uses the term “alarmists” (Line 1. Para. 5) to refer to those who________.A) use standardized measurements in the studies of media violenceB) initiated the debate over the influence of violent media on realityC) assert a direct link between violent media and aggressive behaviorD) use appropriate methodology in examining aggressive behavior24. In refuting the alarmists, the author advances his argument by first challenging________.A) the source and amount of their dataB) the targets of their observationC) their system of measurementD) their definition of violence25. What does the author think of the debate concerning the relationship between themedia and violence?A) More studies should be conducted before conclusions are drawn.B) It should come to an end since the matter has now been settled.C) The past studies in this field have proved to be misleading.D) He more than agrees with the views held by the alarmists.Passage TwoQuestions 26 to 30 are based on the following passage.You‟re in trouble if you have to buy your own brand-name prescription drugs. Over the past decade, prices leaped by more than double the inflation rate. Treatments for chronic conditions can easily top $2,000 a month-no wonder that one in four Americans can‟s afford to fill their prescriptions. The solution? A hearty chorus of “O Canada.” North of the border, where price controls reign, those same brand-name drugs cost 50% to 80% less.The Canadian option is fast becoming a political wake-up call, “If our neighbors canbuy drugs at reasonable prices, why can‟t we? Even to whisper that thought provokes anger. “Un-American!” And-the propagandists‟trump card (王牌)—“Wreck our brilliant health-care system.” Supersize drug prices, they claim, fund the research that sparks the next generation of wonder drugs. No sky-high drug price today, no cure for cancer tomorrow. So shut up and pay up.Common sense tells you that‟s a false alternative. The reward for finding, say, a cancer cure is so huge that no one‟s going to hang it up. Nevertheless, if Canada-level pricing came to the United States, the industry‟s profit margins would drop and the pace of new-drug development would slow. Here lies the American dilemma. Who is all this splendid medicine for? Should our health-care system continue its drive toward the best of the best, even though rising numbers of patients can‟t afford it? Or should we direct our wealth toward letting everyone in on today‟s level of care? Measured by saved lives, the latter is almost certainly the better course.To defend their profits, the drug companies have warned Canadian wholesalers and pharmacies (药房) not to sell to Americans by mail, and are cutting back supplies to those who dare.Meanwhile, the administration is playing the fear card. Officials from the Food and Drug Administration will argue that Canadian drugs might be fake, mishandled, or even a potential threat to life.Do bad drugs fly around the Internet? Sure-and the more we look, the more we‟ll find, But I haven‟t heard of any raging epidemics among the hundreds of thousands of people buying crossborder.Most users of prescription drugs don‟t worry about costs a lot. They‟re sheltered by employee insurance, owing just a $20 co-pay. The financial blows rain, instead, on the uninsured, especially the chronically ill who need expensive drugs to live, This group will still include middle-income seniors on Medicare, who‟ll have to dig deeply into their pockets before getting much from the new drug benefit that starts in 2006.26. What is said about the consequence of the rocketing drug prices in the U.S.?A) A quarter of Americans can‟t afford their prescription drugs.B) Many Americans can‟t afford to see a doctor when they fall ill.C) Many Americans have to go to Canada to get medical treatment.D) The inflation rate has been more than doubled over the years.27. It can be inferred that America can follow the Canadian model and curb its soaringdrug prices by ________.A) encouraging people to buy prescription drugs onlineB) extending medical insurance to all its citizensC) importing low-price prescription drugs from CanadaD) exercising price control on brand-name drugs28. How do propagandists argue for the U.S. drug pricing policy?A) Low prices will affect the quality of medicines in America.B) High prices are essential to funding research on new drugs.C) Low prices will bring about the anger of drug manufacturers.D) High-price drugs are indispensable in curing chronic diseases.29. What should be the priority of America‟s health-care system according to theauthor?A) To resolve the dilemma in the health-care system.B) To maintain America‟s lead in the drug industry.C) To allow the vast majority to enjoy its benefits.D) To quicken the pace of new drug development.30. What are American drug companies doing to protect their high profits?A) Labeling drugs bought from Canada as being fakes.B) Threatening to cut back funding for new drug research.C) Reducing supplies to uncooperative Canadian pharmacies.D) Attributing the raging epidemics to the ineffectiveness of Canadian drugs.Passage ThreeQuestions 31 to 35 are based on the following passage.Age has its privileges in America. And one of the more prominent of them is the senior citizen discount. Anyone who has reached a certain age—in some cases as low as 55—is automatically entitled to a dazzling array of price reductions at nearly every level of commercial life. Eligibility is determined not by one‟s need but by the date on one‟s birth certificate. Practically unheard of a generation ago, the discounts have become a routine part of many businesses—as common as color televisions in motel rooms and free coffee on airliners.People with gray hair often are given the discounts without even asking for them;yet, millions of Americans above age 60 are healthy and solvent (有支付能力的). Businesses that would never dare offer discounts to college students or anyone under 30 freely offer them to older Americans. The practice is acceptable because of the widespread belief that “elderly”and “needy”are synonymous (同义的). Perhaps that once was true, but today elderly Americans as a group have a lower poverty rate than the rest of the population. To be sure, there is economic diversity within the elderly, and many older Americans are poor, But most of them aren‟t.It is impossible to determine the impact of the discounts on individual companies. For many firms, they are a stimulus to revenue. But in other cases the discounts are given at the expense, directly or indirectly, of younger Americans. Moreover, they are a direct irritant in what some politicians and scholars see as a coming conflict between thegenerations.Generational tensions are being fueled by continuing debate over Social Security benefits, which mostly involves a transfer of resources from the young to the old. Employment is another sore point, Buoyed (支持) by laws and court decisions, more and more older Americans are declining the retirement dinner in favor of staying on the job-thereby lessening employment and promotion opportunities for younger workers.Far from a kind of charity they once were, senior citizen discounts have become a formidable economic privilege to a group with millions of members who don‟t need them.It no longer makes sense to treat the elderly as a single group whose economic needs deserve priority over those of others. Senior citizen discounts only enhance the myth that older people can‟t take care of themselves and need special treatment;and they threaten the creation of a new myth, that the elderly are ungrateful and taking for themselves at the expense of children and other age groups. Senior citizen discounts are the essence of the very thing older Americans are fighting against-discrimination by age.31. We learn from the first paragraph that ________.A) offering senior citizens discounts has become routine commercial practiceB) senior citizen discounts have enabled many old people to live a decent lifeC) giving senior citizens discounts has boosted the market for the elderlyD) senior citizens have to show their birth certificates to get a discount32. What assumption lies behind the practice of senior citizen discounts?A) Businesses, having made a lot of profits, should do something for society inreturn.B) Old people are entitled to special treatment for the contribution they made tosociety.C) The elderly, being financially underprivileged, need humane help from society.D) Senior citizen discounts can make up for the inadequacy of the Social Securitysystem.33. According to some politicians and scholars, senior citizen discounts will ________.A) make old people even more dependent on societyB) intensify conflicts between the young and the oldC) have adverse financial impact on business companiesD) bring a marked increase in the companies revenues34. How does the author view the Social Security system?A) It encourages elderly people to retire in time.B) It opens up broad career prospects for young people.C) It benefits the old at the expense of the young.D) It should be reinforced by laws and court decisions.35. Which of the following best summarizes the author‟s main argument?A) Senior citizens should fight hard against age discrimination.B) The elderly are selfish and taking senior discounts for granted.C) Priority should be given to the economic needs of senior citizens.D) Senior citizen discounts may well be a type of age discrimination.Passage FourQuestions 36 to 40 are based on the following passage.In 1854 my great-grandfather, Morris Marable, was sold on an auction block in Georgia for $500. For his white slave master, the sale was just “business as usual.” But to Morris Marable and his heirs, slavery was a crime against our humanity. This pattern of human rights violations against enslaved African-Americans continued under racial segregation for nearly another century.The fundamental problem of American democracy in the 21st century is the problem of “structural racism” the deep patterns of socio-economic inequality and accumulated disadvantage that are coded by race, and constantly justified in public speeches by both racist stereotypes and white indifference. Do Americans have the capacity and vision to remove these structural barriers that deny democratic rights and opportunities to millions of their fellow citizens?This country has previously witnessed two great struggles to achieve a truly multicultural democracy.The First Reconstruction (1865-1877) ended slavery and briefly gave black men voting rights, but gave no meaningful compensation for two centuries of unpaid labor. The promise of “40 acres and a mule (骡子)”was for most blacks a dream deferred (尚未实现的).The Second Reconstruction (1954-1968), or the modern civil rights movement, ended legal segregation in public accommodations and gave blacks voting rights. But these successes paradoxically obscure the tremendous human costs of historically accumulated disadvantage that remain central to black Americans‟ lives.The disproportionate wealth that most whites enjoy today was first constructed from centuries of unpaid black labor. Many white institutions, including some leading universities, insurance companies and banks, profited from slavery. This pattern of white privilege and black inequality continues today.Demanding reparations (赔偿) is not just about compensation for slavery and segregation. It is, more important, an educational campaign to highlight the contemporary reality of “racial deficits” of all kinds, the unequal conditions that impact blacks regardless of class. Structural racism‟s barriers include “equity inequity.” the absence of black capital formation that is a direct consequence of America‟s history. Onethird of all black households actually have negative net wealth. In 1998 the typical black family‟s net wealth was $16,400, less than one fifth that of white families. Black families are denied home loans at twice the rate of whites.Blacks remain the last hired and first fired during recessions. During the 1990-91 recession, African-Americans suffered disproportionately. At Coca-Cola, 42 percent of employees who lost their jobs were blacks. At Sears, 54 percent were black, Blacks have significantly shorter life spans, in part due to racism in the health establishment. Blacks are statistically less likely than whites to be referred for kidney transplants or early-stage cancer surgery.36. To the author, the auction of his great-grandfather is a typical example of ________.A) crime against humanityB) unfair business transactionC) racial conflicts in GeorgiaD) racial segregation in America37. The barrier to democracy in 21st century America is ________.A) widespread use of racist stereotypesB) prejudice against minority groupsC) deep-rooted socio-economic inequalityD) denial of legal rights to ordinary blacks38. What problem remains unsolved in the two Reconstructions?A) Differences between races are deliberately obscured.B) The blacks are not compensated for their unpaid labor.C) There is no guarantee for blacks to exercise their rights.D) The interests of blacks are not protected by law.39. It is clear that the wealth enjoyed by most whites ________.A) has resulted from business successes over the yearsB) has been accompanied by black capital formationC) has derived from sizable investments in educationD) has been accumulated from generations of slavery40. What does the author think of the current situation regarding racial discrimination?A) Racism is not a major obstacle to blacks‟ employment.B) Inequality of many kinds remains virtually untouched.C) A major step has been taken towards reparations.D) Little has been done to ensure blacks‟ civil rights.Part III Vocabulary (20 minutes)Directions: There are 30 incomplete sentences in this part.
