单选题 As anyone who has tried to lose weight knows, realistic goal-setting generally produces the best results. That's partially because it appears people who set realistic goals actually work more efficiently, and exert more effort, to achieve those goals. What's far less understood by scientists, however, are the potentially harmful effects of goal-setting. Newspapers relay daily accounts of goal-setting prevalent in industries and businesses up and down both Wall Street and Main Street, yet there has been surprisingly little research on how the long-trumpeted practice of setting goals may have contributed to the current economic crisis, and unethical (不道德的) behavior in general. 'Goals are widely used and promoted as having really beneficial effects. And yet, the same motivation that can push people to exert more effort in a constructive way could also motivate people to be more likely to engage in unethical behaviors, ' says Maurice Schweitzer, an associate professor at Penn's Wharton School. 'It turns out there's no economic benefit to just having a goal—you just get a psychological benefit. 'Schweitzer says, 'But in many cases, goals have economic rewards that make them more powerful. ' A prime example Schweitzer and his colleagues cite is the 2004 collapse of energy-trading giant Enron, where managers used financial incentives to motivate salesmen to meet specific revenue goals. The problem, Schweitzer says, is the actual trades were not profitable. Other studies have shown that saddling employees with unrealistic goals can compel them to lie, cheat or steal. Such was the case in the early 1990s when Sears imposed a sales quota on its auto repair staff. It prompted employees to overcharge for work and to complete unnecessary repairs on a companywide basis. Schweitzer concedes his research runs counter to a very large body of literature that commends the many benefits of goal-setting. Advocates of the practice have taken issue with his team's use of such evidence as news accounts to support his conclusion that goal-setting is widely over-prescribed. In a rebuttal (反驳) paper, Dr. Edwin Locke writes: 'Goal-setting is not going away. Organizations cannot thrive without being focused on their desired end results any more than an individual can thrive without goals to provide a sense of purpose. ' But Schweitzer contends the 'mounting causal evidence' linking goal-setting and harmful behavior should be studied to help spotlight issues that merit caution and further investigation. 'Even a few negative effects could be so large that they outweigh many positive effects, ' he says. 'Goal-setting does help coordinate and motivate people. My idea would be to combine that with careful oversight, a strong organizational culture, and make sure the goals that you use are going to be constructive and not significantly harm the organization, ' Schweitzer says.

单选题Around the world more and more people are taking part in dangerous sports and activities. Of course, there have always been people who have looked for adventure—those who have climbed the highest mountains, explored unknown parts of the world or sailed in small boats across the greatest oceans. Now, however, there are people who seek an immediate excitement from a risky activity which may only last a few minutes or even seconds. I would consider bungee jumping to be a good example of such an activity. You jump from a high place (perhaps a bridge or a hot-air balloon) 200 meters above the ground with an elastic rope tied to your ankles. You fall at up to 150 kilometers an hour until the rope stops you from hitting the ground. It is estimated that two million people around the world have now tried bungee jumping. Other activities which most people would say are as risky as bungee jumping involve jumping from tall buildings and diving into the sea from the top of high cliffs. Why do people take part in such activities as these? Some psychologists suggest that it is because life in modem societies has become safe and boring. Not very long ago, people"s lives were constantly under threat. They had to go out and hunt for food, diseases could not easily be cured, and life was a continuous battle for survival. Nowadays, according to many people, life offers little excitement. They live and work in comparatively safe environment; they buy food in shops; and there are doctors and hospitals to look after them if they become ill. The answer for some of these people is to seek danger in activities such as bungee jumping.

单选题One in three Americans said that money was a crucial factor in their decision to work for pay (or have a spouse work) rather than stay home to raise the children, with Baby Boomer women most likely to have made that choice. Forty-five percent of Baby Boomer women—compared with just 32 percent of those 55 and over—said they went to work. "Baby Boomer women, especially the older ones, grew up expecting to replicate the pattern of their mothers' lives," suggests Hochschild. "But then the bills started coming in and more job opportunities opened up, and these women moved into a life they hadn't anticipated." Money played a great role in marriage—even an unhappy one. Approximately 18 percent of all those interviewed said they stayed married because they lacked money to get a divorce, while less than 8 percent said that financial strain in their marriage has caused them to divorce. Lack of money also influenced education choices. Nearly one in four Americans has postponed or decided not to attend college because of financial pressures. Even with the sustained prosperity of the past eight years, Gen-Xers were most likely to have altered their college plans. A 39-year-old Hispanic billing clerk in New York spoke about how the need for money limited her teenager son's ability to take part in extracurricular activities that could increase his chances of getting into college. "Since age 14, my son's been working, and I think he is a superb person. Not having a lot of money has made him realize what work is all about. On the other hand, he was elected to go to a youth leadership conference in Washington, and I can't send him because I don't have the money. Lack of money takes away opportunities he otherwise could have had." On the question of what money can and can't buy, a large majority of Americans said that money could buy "freedom to live as you choose", "excitement in life", and "less stress". In a number of follow-up interviews, many people commented that having extra money would immediately alleviate one source of profound stress——the need to work overtime. Those with college and graduate degrees were far more likely to believe that money can buy freedom, perhaps because better-educated people already have a wider array of choices. College-educated professionals, for instance, were much more likely to consider wealth a way of financing travel, starting a business of their own, or funding charitable works in their communities. A 55-year-old Hispanic woman in Los Angeles with a graduate degree and an income of more than＄90,000 described a midlife career switch. After resigning from a high-level, high paying——but extremely stressful—civil service job, she became a florist. "After I Started tearing my hair out," she said, "I decided to go into business for myself—flowers don't talk back." Can money buy peace of mind? Fifty-two percent of Americans said no. "It all depends on what 'peace' means to you," observed a businesswoman in California who is nearing 60 and would like to retire at 62 and go back to college. "For my husband, peace of mind means working as long as he can and collecting the biggest possible pension. For me, it means knowing I've worked long enough so that I can afford to go after an old dream, I guess you should say that my peace of mind is his worry./
