As many as one in four US workers may be often angry on the job, and angry employees also are more likely to get bored, have low energy and feel trapped in their posts, according to a survey. Employees are most likely to be angered by a boss, or by a fellow employee in the workplace not being productive, or by tight deadlines or by heavy workloads, said Donald Gibson, a professor at the Yale University School of Management.
On the one hand, anu nstable economic environment has produced productivity and growth; on the other, it has produced change and uncertainty, which has influenced the wor
kplace negatively. According to Professor Gibson's survey, while a majority of employees are responding to the conditions with reports of workplace satisfaction, there remain a substantial portion who are dissatisfied, even angry at work. Obviously, anger is linked to workplace aggression, which appears to be increasing: We are weekly confronted with stories of workers taking aggressive, even violent action particularly against their boss.
The survey found that 25 percent of tho contacted said they were at least somewhat angry at work on a continuing basis. Angry employees tend to have less energy and interest in the job, and tend also to be bored. And angry employees tend to feel trapped in the job. The study did not discuss what percentage of angry workers are likely to u violence. It did find that they feel less loyal （忠诚的 ） to the employer. There have been a number of workplace shootings in the United States over the years, which is really worrisome.

Questions 6 to 10 are bad on the same passage or dialog. Judging from recent surveys most experts in sleep behavior agree that there is virtually an epidemic of sleeplessness in the US. "I can't think of a single study that hasn't found Americans getting less sleep than they ought to," says Dr. David. "Even people who think they are sleeping enough would probably be better off with more rest."
The beginning of our sleep-deficit （睡眠不足 ） crisis can be traced to the invention of the light bulb a century ago. From diary entries and other personal accounts from the 18th and 19th centuries, sleep scientists have reached the conclusion that the average person ud to sleep about 9.5 hours a night. The best sleep habits once were forced on us, when we had nothing to do in the evening down on the farm, and it was dark. By the 1950s and 1960s, that sleep schedule had been reduced dramatically to between 7.5 and 8 hours, and most people had to wake to an alarm clock. "People cheat on their sleep, and they don't even realize they're doing it," says Dr. David. "They think they're ok becau
they can get by on 6.5 hours, when they really need 7.5, 8 or even more to feel ideally （理想地 ） vigorous."
Perhaps the most merciless robber of sleep, rearchers say, is the complexity of the day. Whenever pressures from work, family, friends and community mount, many people considered energetic if you say you only need 5.5 hours' sleep. If you've got to get 8.5 hours, people think you lack drive and ambition.
To determine the conquences of sleep deficit, rearchers have put subjects through a t of psychological and performance tests requiring them, for instance, to add columns of numbers or recall a passage read to them only minutes earlier. "We've found that if you're in sleep deficit, performance suffers," says Dr. David. "Short-term memory is weakened, as are abilities to make decisions and to concentrate."
6.What can we learn from Dr. David's words in Paragraph 1?
A.All studies have found that Americans should get more sleep.
