单选题Conventional wisdom about conflict seems pretty much cut and dried. Too little conflict breeds apathy (冷淡) and stagnation (呆滞). Too much conflict leads to divisiveness (分裂) 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 simple generalizations. He studied perceptions of conflict among a sample of executives. Some of the executives worked for profit-seeking organizations and others for not-for-profit organizations. Somewhat surprisingly, Schwenk found that opinions about conflict varied systematically as a function of the 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 different 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-making 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 complexities and ambiguities associated with satisfying many diverse constituents executives perceived that conflict led to more considered and acceptable decisions.

单选题One of our expectations about education is that it will pay off in terms of upward mobility. Historically, the correlation between education and income has been strong. But in the early 1970s, a contradiction 26 between education and the economy. Our value of education and our average educational attainment outstripped the capacity of the economy to 27 the graduates. Experts have argued that this contradiction is at the heart of the problem of public education today. It is not, as business leaders claim, that the schools are failing to 28 educate students. The real problem is a dearth (缺乏) of economic 29 for students who are not continuing on to college. College graduates also are having difficulty finding jobs. Even when they do, the jobs may not be commensurate (相称的) with their 30 and expectations. Part of the problem is that too many young Americans aspire to have professional jobs, making disappointment and frustration 31 for some. Another part of the problem is the assumption that greater educational attainment guarantees career 32 . In fact, employers do not routinely reward educational attainment; 33 , they reward it only when they believe it will contribute to the employee's productivity. We should not overlook the fact that there is still a strong correlation between education, occupation, and income. College graduates have a strong advantage over those with less education. Despite the fact that the payoff is neither as large nor as 34 as it once was, we could still argue that all or at least the majority of Americans would 35 by some degree because higher education can enable them to think more deeply, explore more widely, and enjoy a greater range of experiences. A. absorb B. advancement C. benefit D. certain E. created F. developed G. failure H. gain I. inevitable J. opportunities K. properly L. rather M. thus N. timely O. training
