23、 coming at us so fast that we hardly have time to digest one before the next one hits test-tube babies, egg donation, surrogacy, cloning and now sex selection. And just as with earlier methods, the new sperm-separation technique announced last week has triggered plenty of ethical concern. Only a few

24、 critics have argued that tampering with nature to avoid a sex-linked genetic disease should be taboo. But plenty have expressed misgivings about using the new technology more casually, to balance families, or simply because parents prefer boys or girls. Such choices, critics say, could lead to an i

25、mbalance in the sex ratio, with drastic consequences for society.These arguments are not very persuasive. In some developing countries where boys are more highly valued than girls, sex selection is already standard practice, accomplished by means of infanticide of amniocentesis and abortion. The new

26、 sperm-separation technique makes it easier for more people to practice sex selection in these countries.This could skew the already tilting sex ratio even further in favor of boys. In the short term, such demographic shifts could cause enormous societal problems as men, for example, find it increas

27、ingly difficult to find women to marry. In the long term, however, both evolutionary and economic theories tell us that as girls become scarcer, they will become more highly valued, perhaps to the point at which more people will select for girls than against them.In America and other Western countri

28、es there seems to be little chance of the sexes going far out of balance at all. Polls show that a majority of Americans view a perfect family as having one boy and one girl. If everyone used sex selection to achieve perfection, the result would be perfect balance. Of course, some prospective parent

29、s do prefer children of one sex or the other. But such preferences would presumably balance out as well.Regarding the argument that choosing gender goes against nature: the same objection was used in earlier times by people horrified by vaccines or heart transplants, which are now completely accepta

30、ble. Every time we use medicine to cure a disease or prevent a death, we go against nature willingly. Admittedly, sex selection for family balancing cures no disease. In fact, though, no form of baby making solves a medical problem. Sex selection, moreover, is medically benign in comparison with mos

31、t reproductive technologies. No surgery is involved, and the entire process can theoretically be performed without a physician. Children born through this process cant distinguish from other children.For these reasons, I suspect that as sex selection and other reproductive technologies become more e

32、fficient and less costly, they may be embraced by American families of even modest means who ask themselves, why not? What was once unimaginable could become routine and the link between the sex act and reproduction will no longer be seen as sacred. Ultimately, this may prove to be the real signific

33、ance of sex selection: by breaching a powerful psychological barrier, it will pave the way for true designer babies, who could really turn society upside down.（分数：5.00）(1).Which of the following is not a worry to many people about new ways of baby making? A. Sex selection goes against nature. B. Cho

34、osing gender leads to an imbalance in the sex ratio. C. Preference of a boy over a girl will be terrible for society. D. It is impossible to avoid a sex-linked genetic disease.（分数：1.00）A.B.C.D.(2).According to the writer, in some developing countries sex selection _. A. is illegal by means of infant

35、icide of amniocentesis and abortion B. would result in more difficult statistical survey of population C. would be likely to keep balance of the sexes in the end D. would meet peoples need for sex discrimination（分数：1.00）A.B.C.D.(3).Which of the following statements is true? A. The sexes go far out o

36、f balance in Western countries. B. Perfect balance would not be achieved in view of an American perfect family. C. Evolutionary and economic theories both predict balance of sex ratio in the long run. D. It is high time for us to prevent sex selection from becoming routine.（分数：1.00）A.B.C.D.(4).The w

37、riters reasons for choosing gender show that _. A. it is natural for people to object even if it is better than other reproductive technologies B. it is easy for people to practice sex selection with no surgery and a physician involved C. vaccines or heart transplants which once horrified people are

38、 now completely acceptable D. even poor people may accept it because they will have cleverer children through the process of sex selection（分数：1.00）A.B.C.D.(5).The writers main point in writing this article is _. A. we should pave the way for the designer baby B. picking a babys sex may lead to disas

Too little conflict breeds apahty and stagnation. Too much conflic

40、t leads to divisiveness and hostility. Moderate levels of conflict, however, can spark creativity and motivate people in a healthy and competitive way.Recent research by Professor Charles R. Schwenk, however, suggests that the optimal level of conflict may be more complex to determine than these sim

41、ple generalizations. He studied perceptions of conflict among a sample of executives. Some of the executives worked for profit seeking organizations and other for not-for-profit organizations.Somewhat surprisingly, Schwenk found that opinions about conflict varied systematically as a function of the

42、 type of organization. Specifically, managers in not-for-profit organizations strongly believed that conflict was beneficial to their organizations and that it promoted higher quality decision-making than might be achieved in the absence of conflict.Managers of for-profit organizations saw a differe

43、nt picture. They believed that conflict generally was damaging and usually led to poor-quality decision-making in their organizations. Schwenk interpreted these results in terms of the criteria for effective decision-making suggested by the executives. In the profit-seeking organizations, decision-m

44、aking effectiveness was most often assessed in financial terms. The executives believed that consensus rather than conflict enhanced financial indicators.In the not-for-profit organizations, decision-making effectiveness was defined from the perspective of satisfying constituents. Given the complexi

45、ties and ambiguities associated with satisfying many diverse constituents, the executives perceived that conflict led to more considered and acceptable decisions.（分数：4.00）(1).In the eyes of the author, conventional opinion on conflict is _. A. oversimplified B. misleading C. wrong D. unclear（分数：0.80

A. the advantages and disadvantages of conflict B. the difficulty in determining optimal level of conflict C. the Complexity of defining the roles of conflict D. the real value of conflict（分数：0.80）A.B.C.D.(3).We can learn from Schwenks research that _.
