Question 10 is based on the passage you have just heard.

  “Too many people view their jobs as a five-day prison, which they are paroled every Friday,” says Joel Goodman, founder of The Humor Project, a humor-consulting group in Saratoga Springs, New York. (9) [Humor unlocks the office prison because it lets adults bring some of their childlike spirit to the job. ]

        According to Howard Pollio, professor of psychology at the University of Tennessee, Knoxville, an office with humor breaks is an office with satisfied and productive employees. (10)[Pollio conducted a study that proved humor can help workers excel at routine production tasks.] Employees perform better when they have fun. In large corporations with a hierarchy of power, there is often no outlet for stress. “Every company needs underground ways of poking fun at the organization, ”says Lynn M. Mark, a speaker on workplace humor for Saint Mary’s Health Center in St. Louis.

        Kodak’s Rochester, New York branch discovered a way for its 20,000 employees to uncork their bottled-up resentments. Their 1,000-square-foot “humor room” features a toy store. Among the room’s many stress-reducing gadgets, the main attraction is a boss doll with detachable arms and legs. (11)[ Employees can take the doll apart as long as they put its arms and legs back in place. ]

        Sandy Cohen, owner of a graphic print production business, created “the quote board” to document the bizarre phrases people say when under strict deadlines. “When you’re under stress, you say stupid things,” says Cohen. Now we just look at each other and say “That’s one for the quote board”. 

10. What does the study by Howard Pollio show? （霍华德·波利奥的研究表明了什么？）

解析：D。录音中间部分提到，波利奥进行的一项研究证明，幽默可以帮助员工在常规任务中表现出色，D项的excel at routine tasks对应录音中的excel at routine production tasks，因此选D。

错项排除：录音开始提到很多人将一周的工作视为五天监禁，每逢周五才能获得假释，A项中的Weekends是针对此内容进行的干扰，但这并非波利奥的研究，故排除。录音中在说波利奥的研究时，并未提到interpersonal relationships（人际关系），故B项排除。录音中提到，在大公司工作的员工压力往往没有释放的出口，但这并不等于所有员工都有情绪压力，而且这也不是波利奥的研究发现，故C项排除。
