单选题People who sleep about seven hours a night live the longest, three huge studies have found, the newest out in the February issue of the journal SLEEP. Still, many sleep experts say lots of adults get too little rest, and that can lead to dangerous health problems. In the latest report from Japanese researchers, 104,010 adults were followed for about ten years. At the start, the participants answered questionnaires about their sleep patterns, and about their health, mental health and lifestyle habits, which can also affect survival. After accounting for all of these factors, adults getting an average of seven hours had the lowest death rates. Surprisingly, less sleep, even as little as four hours a night, didn"t significantly increase deaths for men and only lowered survival for women if they averaged less than four hours. But adults who slept longer than seven hours, particularly women, were more likely to die during the ten years. Doctors shouldn"t tell all of their patients to get at least eight hours of sleep, he says in an editorial in the journal. Hormonal(荷尔蒙的) changes caused by darkness or other unknown biological effects from long sleep could be affecting survival, Kripke says. But short sleepers may suffer other bad effects. In his brief studies, those sleeping four to five and a half hours did poorly on tests that measure memory, clear thinking and the ability to pay attention, "and they did progressively worse as the week went on," says David Dinges of the University of Pennsylvania School of Medicine. Adults who slept about seven hours performed best, he says.

单选题Psychologists take opposing views of how external rewards, from warm praise to cold cash, affect motivation and creativity. Behaviorists, who study the relation between actions and their consequences, argue that rewards can improve performance at work and school. Cognitive (认知学派的) researchers, who study various aspects of mental life, maintain that rewards often destroy creativity by encouraging dependence on approval and gifts from others. The latter view has gained many supporters, especially among educators. But the careful use of small monetary(金钱的)rewards sparks creativity in grade-school children, suggesting that properly presented inducements(刺激)indeed aid inventiveness, according to a study in the June Journal of Personality and Social Psychology. "If kids know they're working for a reward and can focus on a relatively challenging task, they show the most creativity, ' says Robert Eisenberger of the University of Delaware in Newark." But it's easy to kill creativity by giving rewards for poor performance of creating too much anticipation for rewards." A teacher who continually draws attention to rewards or who hands out high grades for ordinary achievement ends up with uninspired students, Eisenberger holds. As an ex- ample of the latter point, he notes growing efforts at major universities to tighten grading standards and restore failing grades. In earlier grades, the use of so-called token economies, in which students handle challenging problems and receive performance-based points toward valued rewards, shows promise in raising effort and creativity, the Delaware psychologist claims.

单选题 Your boss holds your future prospects in his hands. Some bosses are hard to get along with. Some have excellent qualifications but no idea when it comes to dealing with people. Of course, not all bosses are like that. The relationship you have with your boss can be a major factor in determining your rise up the career ladder. Your boss is not only your leader, he is also the person best equipped to help you do the job you are paid to do. He can inform you of company direction that may affect your professional development. Your boss also needs you to perform at your best in order to accomplish his objectives. He needs your feedback in order to provide realistic and useful reports to upper management. But how does this help you establish a meaningful working relationship with your boss? The key is communication. Learn and understand his goals and priorities (优先的事). Observe and understand your boss's work style. If he has not been clear with his expectations, ask! Likewise, ask for feedback and accept criticism gracefully. And if he understands that you do not view your job as just something to fill the hours between 9 and 5, he may be more likely to help you. In short, getting along with your boss requires getting to know his likes and dislikes and learning to work with his personality and management style.
