阅读理解。 A survey (调查)by an international temporary service agency found that US managers believe that people with a sense of humour do better in their jobs, compared with those who have little or no sense of humour. In fact, about 96 percent of those surveyed said people with a sense of humour do better. The survey went on to point out that the results suggested that a sense of humour may help lighthearted employees keep their jobs during tough times. And, what's more, it may push them up the corporate ladder past their humourless colleagues. Why? It seems that those with a sense of humour are better communicators and better team players. Studies have shown that happy workers are more productive. In fact, a researcher at California State University found that humour could help employees release tension. Research done by psychologist Dr. Ashton Trice at Mary Baldwin College in Virginia showed that humour helps us think. When people feel stuck on important projects, they tend to feel angry or depressed. According to Dr. Trice's research,sparing time to laugh can help us get rid of negative feelings and allow us to return to a task or move on to another project unaffected by past defeat. If humour is really so important, then why don't we use it more often on the job? Most likely, the main reason is that many people are unaware of the positive effects of humour in the workplace. However,it is important to realize that some humour is not suitable for the workplace, and that it is often used at the wrong time. 1. Most people think a sense of humour can ________.
