Many whites and blac
23、ks alike scoffed 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
24、case when the 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
25、to the United 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 Stateswealth, opponents contend, blacks benefit from that wealth today. As a group, Afro-Am
26、ericans 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
27、 National 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 p
28、erished 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 financ
29、ial 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 insura
30、nce 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 emancipati
31、on 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 _. A. compensations usually go to direct victims B. blacks who came aft
32、er slavery ended should not receive compensations C. blacks now are enjoying the wealth they created under slavery D. some blacks were slave owners instead of slaves（分数：1.00）A.B.C.D.(2).“Immigrants“ in paragraph 3 refers to _. A. Afro-Americans B. non-white immigrants C. Japanese-Americans D. holoca
33、ust survivors（分数：1.00）A.B.C.D.(3).That the reparations movement is winning support in America is shown in the fact that _. A. federal hearings were held to investigate the impact of slavery B. even mainstream civil rights groups were persuaded C. growing attention is being paid to the wealth of the
34、blacks D. there was more public awareness of the frightening experience of slavery（分数：1.00）A.B.C.D.(4).The two private companies that made public apology had _. A. compensated slave owners for financial losses B. sold slaves and captured runaways C. operated insurance and advertisement businesses D.
35、 depended on slavery for their existence（分数：1.00）A.B.C.D.(5).Which of the following is true according to the passage? A. US government killed Japanese-Americans during World War . B. A new Californian law disclosed slave-insurance policies. C. National Urban League is one of the civil rights groups.
36、 D. Blacks faced no discrimination after liberation in 1865.（分数：1.00）A.B.C.D.九、BPassage 2/B(总题数：1，分数：5.00)We all know that DNA has the ability to identify individuals but, because it is inherited, there are also regions of the DNA strand which can relate an individual to his or her family (immediate
37、 and extended), tribal group and even an entire population. Molecular Genealogy (宗谱学) can use this unique identification provided by the genetic markers to link people together into family trees. Pedigrees (家谱) based on such genetic markers can mean a break-through for family trees where information
38、 is incomplete or missing due to adoption, illegitimacy or lack of records. There are many communities and populations which have lost precious records due to tragic events such as the fire in the Irish courts during Civil War in 1921 or American slaves for whom many records were never kept in the f
39、irst place.The main objective of the Molecular Genealogy Research Group is to build a database containing over 100,000 DNA samples from individuals all over the world. These individuals will have provided a pedigree chart of at least four generations and a small blood sample. Once the database has e
40、nough samples to represent the world genetic make-up, it will eventually help in solving many issues regarding genealogies that could not be done by relying only on traditional written records. Theoretically, any individual will someday be able to trace his or her family origins through this databas
41、e.In the meantime, as the database is being created, molecular genealogy can already verify possible or suspected relationships between individuals. “For example, if two men sharing the same last name believe that they are related, but no written record proves this relationship, we can verify this p
42、ossibility by collecting a sample of DNA from both and looking for common markers (in this case we can look primarily at the Y chromosome (染色体),“ explains George Green, a member of the BYU Molecular Genealogy research team.（分数：5.00）(1).People in a large area may possess the same DNA thread because_.
43、 A. DNA is characteristic of a region B. they are beyond doubt of common ancestry C. DNA strand has the ability to identify individuals D. their unique identification can be provided via DNA（分数：1.00）A.B.C.D.(2).The possible research of family trees is based on the fact that_. A. genetics has achieve
44、d a breakthrough B. genetic information contained in DNA can be revealed now C. each individual carries a unique record of who he is and how he is related to others D. we can use DNA to prove how distant an individual is to a family, a group or a population（分数：1.00）A.B.C.D.(3).The Molecular Genealog
45、y Research Group is building a database for the purpose of_. A. offering assistance in working out genealogy-related problems B. solving many issues without relying on traditional written records C. providing a pedigree chart of at least four generations in the world D. confirming the assumption tha
46、t all individuals are of the same origin（分数：1.00）A.B.C.D.(4).If two men suspected for some reason they have a common ancestor, _. A. we can decide according to their family tree B. we can find the truth from their genetic markers C. we can compare the differences in their Y chromosome D. we can look for written records to prove their relationship（分数：1.00）A.B.C.D.(5).Which of the following CANNOT be inferred from the passage? A. We are a walking, living, breathing record of our ancestors. B. Many
