Many whites and blacks alike sco

10、ffed at the idea, reasoning that slavery is part of the past that would only unleash new demons if it were resurrected. Opponents contend that the fledgling reparations movement overlooks many important facts. First, they assert, reparations usually are paid to direct victims, as was the case when t

11、he US government apologized and paid compensation to Japanese-Americans interned during World War . Similarly, Holocaust survivors have received payments from the Germans. In addition, not all blacks were slaves, and an estimated 3, 000 were slave owners. Also, many immigrants not only came to the U

12、nited States after slavery ended, but they also faced discrimination. Should they be paid reparations, too? Or should they receive them? And regardless of how much slave labor contributed to the United States“ wealth, opponents contend, blacks benefit from that wealth today. As a group, Afro-America

13、ns are the best-educated, wealthiest blacks on the planet. But that attitude is slowly changing. At least 10 cities, including Chicago, Detroit and Washington, have passed resolutions in the past two years urging federal hearings into the impact of slavery. Mainstream civil rights groups such as Nat

14、ional Association for the Advancement of Colored People, the National Urban League and the Southern Christian Leadership Conference regularly raise the issue. The surging interest in reparations parallels a heightened sensitivity to the horrors of slavery, in which as many as 6 million Africans peri

15、shed in the journey to the Americas alone. There also is growing attention being paid to the huge economic bounty that slavery created for private companies and the country as a whole. Earliest this year, Aetna Inc. apologized for selling insurance policies that compensated slave owners for financia

16、l losses when their slaves died. Last summer, the Hartford Courant in Connecticut printed a front-page apology for the profits it made from running ads for the sale of slaves and the capture of runaways. Next month, a new California law will require insurance companies to disclose any slave insuranc

17、e policies they may have issued. The state also is requiring University of Californian officials to assemble a team of scholars to research the history of slavery and report how current California businesses benefited. Proponents of reparations argue that, even for nearly a century after emancipatio

18、n in 1865, blacks legally were still excluded from the opportunities that became the cornerstones for the white middle-class.（分数：5.00）(1).The reasons put forward by opponents of reparations include all the following EXCEPT that _.（分数：1.00）A.compensations usually go to direct victimsB.blacks who came

19、 after slavery ended should not receive compensationsC.blacks now are enjoying the wealth they created under slaveryD.some blacks were slave owners instead of slaves(2).“Immigrants“ in paragraph 3 refers to _.（分数：1.00）A.Afro-AmericansB.non-white immigrantsC.Japanese-AmericansD.holocaust survivors(3)

20、That the reparations movement is winning support in America is shown in the fact that _.（分数：1.00）A.federal hearings were held to investigate the impact of slaveryB.even mainstream civil rights groups were persuadedC.growing attention is being paid to the wealth of the blacksD.there was more public

21、awareness of the frightening experience of slavery(4).The two private companies that made public apology had _.（分数：1.00）A.compensated slave owners for financial lossesB.sold slaves and captured runawaysC.operated insurance and advertisement businessesD.depended on slavery for their existence(5).Whic

23、ssage 2(总题数：1，分数：20.00)Stanford University scientists have weighed in on the “maybe not“ side of the debate after an extensive examination of four decades of research comparing organic and conventional foods. They concluded that fruits and vegetables labeled organic were, on average, not more nutrit

24、ious than their conventional counterparts, which tend to be far less expensive. Nor were they any less likely to be contaminated by dangerous bacteria like E. coli. The researchers also found no obvious health advantages of organic meats. Conventional fruits and vegetables did have more pesticide re

25、sidue, but the levels were almost always under the allowed safety limits, the scientists said. “When we began this project, we thought that there would likely be some findings that would support the superiority of organics over conventional foods,“ said Dr. Dena Bravata, a senior affiliate of Stanfo

26、rd“s Center for Health Policy and the senior author of the paper, which appears in Tuesday“s issue of the Annals of Internal Medicine. “I think we were definitely surprised.“ In the studyknown as a meta-analysis, in which previous findings are aggregated but no new laboratory work is conductedresear

27、chers combined data from 237 studies, examining a wide variety of fruits, vegetables and meats. For four years, they performed statistical analyses looking for signs of health benefits from adding organic foods to the diet. The researchers did not use any outside financing for their research. “I rea

28、lly wanted us to have no perception of bias,“ Dr. Bravata said. The study“s conclusions about pesticides did seem likely to please organic food customers. Over all, the Stanford researchers concluded that 38 percent of conventional products tested in the studies contained detectable residues, compar

29、ed with 7 percent for the organic produce. (Even products grown organically can be tainted by pesticides wafting over from a neighboring field or during processing and transporting.) They also noted a couple of studies that showed that children who ate organic produce had fewer pesticide traces in t

30、heir urine. Dr. Bravata agreed that people bought organic food for a variety of reasonsconcerns about the effects of pesticides on young children, the environmental impact of large-scale conventional farming and the potential public health threat if antibiotic-resistant bacterial genes jumped to hum

31、an pathogens. “Those are perfectly valid,“ she said. But if the choices were based mainly on the hope that organic foods would provide more nutrients, “I would say there is no robust evidence to choose one or the other,“ Dr. Bravata said.（分数：20.00）(1).According to Dr. Bravata, it is _ for people to

32、think that organics are better than conventional foods.（分数：4.00）A.naturalB.difficultC.surprisingD.impossible(2).Which of the following statements is TRUE?（分数：4.00）A.Organic fruits and vegetables have more pesticide residue.B.Organic fruits and vegetables tend to be less expensive.C.The research was

33、based on previous findings.D.The research used an outside financing.(3).People bought organic foods for different reasons EXCEPT _.（分数：4.00）A.the public health threatB.worrying about the pesticidesC.the price advantages of organic foodsD.the environment of conventional farming(4).What does the last

34、sentence mean?（分数：4.00）A.It is unnecessary for people to buy organic foods.B.It is necessary for people to buy conventional foods.C.Organic foods is better than conventional foods.D.Organic foods can not provide more nutrients.(5).The passage focuses on _.（分数：4.00）A.the prices of the organic foodsB.

35、the qualities of the organic foodsC.the nutrients of the organic foodsD.the pesticide residues of the organic foods六、Passage 3(总题数：1，分数：5.00)No company likes to be told it is contributing to the moral decline of a nation. “Is this what you like to accomplish with your careers?“ an American senator a

36、sked Time Warner executives recently. “You have sold your souls, but must you corrupt our nation and threaten our children as well?“ At Time Warner, however, such questions are simply the latest manifestation of the soulsearching that has involved the company ever since the company was born in 1990.

37、 It“s a self-examination that has, at different times, involved issues of responsibility, creative freedom and the corporate bottom line. At the core of this debate is chairman Gerald Levin, 56, who took over from the late Steve Ross in the early 1990s. On the financial front, Levin is under pressur

38、e to raise the stock price and reduce the company“s mountainous debt, which will increase to $17.3 billion after two new cable deals close. He has promised to sell off some of the property and restructure the company, but investors are waiting impatiently. The flap over rap is not making life any ea

39、sier for him. Levin has consistently defended the company“s rap music on the grounds of expression. In 1992, when Time Warner was under fire for releasing Ice-T“s violent rap song Cop Killer, Levin described rap as a lawful expression of street culture, which deserves an outlet. “The test of any dem

40、ocratic society, “he wrote in a Wall Street Journal column, “lies not in how well it can control expression but in whether it gives freedom of thought and expression the widest possible latitude, however disputable or irritating the results may sometimes be. We won“t retreat when we face any threats

41、 “ Levin would not comment on the debate last week, but there were signs that the chairman was backing off his hard-line stand, at least to some extent. During the discussion of rock singing verses at last month“s stockholders“ meeting, Levin asserted that “music is not the cause of society“s ills“

42、 and even cited his son, a teacher in the Bronx, New York, who uses rap to communicate with students. But he talked as well about the “balanced struggle“ between creative freedom and social responsibility, and he proclaimed that the company would launch a drive to develop standards for distribution

43、and labeling of potentially objectionable music. The 15-member Time Warner board is generally supportive of Levin and his corporate strategy. But insiders say some of them have shown their concerns in this matter. “Some of us have known for many, many years that the freedoms under the First Amendmen

44、t are not totally unlimited, “says Luce. “I think it is perhaps the case that some people associated with the company have only recently come to realize this. “（分数：5.00）(1).An American senator criticized Time Warner for _.（分数：1.00）A.its raising of the corporate stock priceB.its self-examination of t

45、he soulC.its neglect of social responsibilityD.its emphasis on creative freedom(2).The word “flap“ ( Para. 3 ) here means _.（分数：1.00）A.controversyB.fearC.disasterD.solution(3).In 1992, Time Warner caused public outrage because it _.（分数：1.00）A.sacked workers as a result of restructuringB.issued a rec

46、ord promoting violenceC.advocated the culture of the streetD.challenged the freedom of expression in democratic society(4).In the face of recent attacks on the company, Levin _.（分数：1.00）A.stuck to a strong stand to defend freedom of expressionB.softened his tone and introduced a new initiativeC.yiel

47、ded to objections and resigned from the companyD.requested unconditional support from the 15-member board(5).We can infer from the last paragraph that _.（分数：1.00）A.profits and social responsibility can rarely go hand in hand in the companyB.few people are concerned about corporate responsibilityC.th

48、e debate over Time Warner“ s policy will soon involve other companiesD.the Time Warner Board“s opinion of the company“s policy is divided七、Passage 4(总题数：1，分数：5.00)Orchids are unique in having the most highly developed of all blossoms, in which the usual male and female reproductive organs are fused

49、in a single structure called the column. The column is designed so that a single pollination will fertilize hundreds of thousands, and in some cases millions, of seeds, so microscopic and light that they are easily carried by the breeze. Surrounding the column are three sepals and three petals, sometimes easily recognizable as such, often distorted into gorgeous, weird, but always functional shapes. The most noticeable of the petals is called the labellum, or lip. It is often dramatically marked as an unmistakable landing str
