尽管人为什么要睡觉这一头号题我们尚未弄清楚,但毫无疑问,人需要睡觉,其他动物也是如此。醒与睡的交替模式是与我们的习惯和感官密切相关的。动物靠视力寻找食物、栖息地和庇护,它们与人一样白天的大部分时间活动,晚上睡觉。为保持身体健康,一个人所需的睡眠时间因年龄不同而大不相同。学龄前儿童通常需要10~12个小时的睡眠时间,中小学生9~11个小时,成年人7~9个小时。成年人随着日益变老所需睡眠时间似乎也逐渐减少。睡眠时间也随种族不同而不同。据说,日本人,包括儿童和成年人,睡眠时间比欧洲人少。但这种不同也许是由于生活习惯而不是由于种族的原因造成的。

第5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.

In the eyes of the author, conventional opinion on conflict is ______.

A.wrong

B.oversimplified

C.misleading

D.unclear

We sometimes think humans are uniquely vulnerable to anxiety, but stress seems to affect the immune defenses of lower animals too. In one experiment, for example, behavioral immunologist (免疫学家) Mark Laudenslager, at the University of Denver, gave mild electric shocks to 24 rats. Half the animals could switch off the current by turning a wheel in their enclosure, while the other half could not. The rats in the two groups were paired so that each time one rat turned the wheel it protected both itself and its helpless Partner from the shock. Laudenslager found that the immune response was depressed below normal in the helpless rats but not in those that could turn off the electricity. What he has demonstrated, he believes, is that lack of control over an event, not the experience itself, is what wakens the immune system.

Other researchers agree. Jay Weiss, a psychologist at Duke University School of Medicine, has shown that animals who are allowed to control unpleasant stimuli don't develop sleep disturbances or changes in brain chemistry typical of stressed rats. But if the animals are conditioned to confront with situations they have no control over, they later behave passively even when faced with experiences they can control. Such findings reinforce psychologists' suspicions that the experience or perception of helplessness, is one of the most harmful factors in depression.

One of the most startling examples of how the mind can alter the immune response was discovered by chance. In 1975 psychologist Robert Ader at the University of Rochester School of Medicine conditioned (便形成条件反射) mice to avoid saccharin (糖精) by simultaneously feeding them the sweetener and injecting them with a drug that while suppressing their immune systems caused stomach upsets. Associating the saccharin with the stomach pains, the mice quickly learned to avoid the sweetener. In order to extinguish this dislike for the sweetener, Ader reexposed the animals to saccharin, this time without the drug, and was astonished to find that those mice that had received the highest amounts of sweetener during their earlier conditioning died. He could only speculate that he had so successfully conditioned the rats that saccharin alone now served to weaken their immune systems enough to kill them.

Laudenslager's experiment showed that the immune system of those rats who could turn off the electricity ______

A.was altered

B.was strengthened

C.was weakened

D.was not affected

Before the 1850's the United States had a number of small colleges, most of them dating from colonial days. They were small, church-connected institutions whose primary concern was to shape the moral character of their students.

Throughout Europe, institutions of higher learning had developed, bearing the ancient name of university. In Germany a different kind of university had developed. The German university was concerned primarily with creating and spreading knowledge, not morals. Between mid-century and the end of the 1800's, more than nine thousand young Americans, dissatisfied with their training at home, went to Germany for advanced study. Some of them returned to become presidents of venerable (受人尊敬的) colleges—Harvard, Yale, Columbia—and transform. them into modern universities. The new presidents broke all ties with the churches and brought in a new kind of faculty. Professors were hired for their knowledge of a subject, not because they were of the proper faith and had a strong arm for disciplining students. The new principle was that a university was to create knowledge as well as pass it on, and this called for a faculty composed of teacher scholars. Drilling and learning by rote (死记硬背) were replaced by the German method of lecturing, in which the professor's own research was presented in class. Graduate training leading to the Ph. D, an ancient German degree signifying the highest level of advanced scholarly attainment, was introduced. With the establishment of the seminar system, graduate students learned to question, analyze, and conduct their own research.

At the same time, the new university greatly expanded in size and course offerings, breaking completely out of the old, constricted curriculum of mathematics, classics, rhetoric, and music. The president of Harvard pioneered the elective system, by which students were able to choose their own courses of study. The notion of major fields of study emerged. The new goal was to make the university relevant to the real pursuits of the world. Paying close heed to the practical needs of society, the new universities trained men and women to work at its tasks, with engineering students being the most characteristic of the new regime. Students were also trained as economists, architects, agriculturalists, social welfare workers, and teachers.

The word "this" (Sentence 8, Para. 2) refers to which of the following?

A.Creating and passing on knowledge.

B.Drilling and learning by rote.

C.Disciplining students.

D.Developing moral principles.

It may look like just another playgroup, but a unique educational center in Manhattan is really giving babies something to talk about. "It's a school to teach languages to babies and young children with games, songs--some of the classes also have arts and crafts," said Francois Thibaut, the founder of the Language Workshop for Children, a place where babies become bilingual.

Children as young as few months are exposed to French and Spanish before many of them can even speak English. Educators use special songs and visual (视觉的) aids to ensure that when a child is ready to talk, the languages will not be so foreign. "Children have a unique capacity to learn many languages at the same time," said Thibaut. "Already at nine months, a child can tell the differences between the sounds he or she has heard since birth and the sounds he or she has never heard yet." Thibaut says the best time to expose children to language is from birth to 3 years old. For the last 30 years, the school has been using what it calls the Thibarut Technique, a system that combines language lessons with child's play.

"I always wanted to learn Spanish, but by the time I got to high school it was too late to pick it up and speak fluently," said Marc Lazare, who enrolled his son at the school. "I figured at this age, two, it's a perfect time for him to learn."

Aside from learning a language, the kids also gain a tremendous sense of confidence. One young student boasted that aside from French, she can speak five languages (though that included "monkey" and "lion"). The school gives children the tools to communicate, and sometimes that gives them an advantage over their parents. "I think they sometimes speak French when they think I won't understand them," said parent Foster Gibbons.

Depending on the age group, classes run from 45 minute up to 2 hours. Even when students are not in class, the program is designed to make sure the learning continues at home. Tapes and books are included so kids can practice on their own.

The word "bilingual" in the first paragraph probably means ______

A.capable of using two languages

B.both clever and confident

C.aware of their own limitations and strengths

D.independent of their parents

Henry Ford, the famous U.S. inventor and car manufacturer, once said, "The business of America is business." By this he meant that the U.S. way of life is based on the values of the business world.

Few would argue with Ford's statement. A brief glimpse at a daffy newspaper vividly shows how much people in the United States think about business. For example, nearly every newspaper has a business section, in which the deals and projects, finances and management, stock prices and labor problems of corporations are reported daily. In addition, business news can appear in every other section. Most national news has an important financial aspect to it. Welfare, foreign aid, the federal budget, and the policies of the Federal Reserve Bank are all heavily affected by business. Moreover, business news appears in some of the unlikeliest places. The world of arts and entertainment is often referred to as "the entertainment industry" or "show business".

The positive side of Henry Ford's statement can be seen in the prosperity that business has brought to U.S. life. One of the most important reasons so many people from all over the world come to live in the United States is the dream of a better job. Jobs are produced in abundance because the U.S. economic system is driven by competition. People believe that this system creates more wealth, more jobs, and a materially better way of life.

The negative side of Henry Ford's statement, however, can be seen when the word business is taken to mean big business. And the term big business—referring to the biggest companies—is seen in opposition to labor. Throughout U.S. history working people have had to fight hard for higher wages, better working conditions, and the fight to form. unions. Today, many of the old labor disputes are over, but there is still some employee anxiety. Downsizing—the driving away of thousands of workers to keep expenses low and profits high—creates

feelings of insecurity for many.

The United States is a country ______ .

A.which encourages free trade at home and abroad

B.where people's chief concern is how to make money

C.where all businesses are managed scientifically

D.which normally works according to the federal budget
