单选题 Baekeland and Hartmann report that the 'short sleepers' had been more or less average in their sleep needs until the men were in their teens. But at about age 15 or so, the men voluntarily began cutting down their nightly sleep time because of pressures from school, work, and other activities. These men tended to view their nightly periods of unconsciousness as bothersome interruptions in their daily routines.
In general, these 'short sleepers' appeared ambitious, active, energetic, cheerful, conformist in their opinions, and very sure about their career choices. They often held several jobs at once, or worked full-or part-time while going to school. And many of them had a strong urge to appear 'normal' or 'acceptable' to their friends and associates.
When asked to recall their dreams, the 'short sleepers' did poorly. More than this, they seemed to prefer not remembering. In similar fashion, their usual way of dealing with psychological problems was to deny that the problem existed, and then to keep busy in the hope that the trouble would go away.
The sleep patterns of the 'short sleepers' were similar to, but less extreme than, sleep patterns shown by many mental patients categorized as manic.
The 'long sleepers' were quite different indeed. Baekeland and Hartmann report that these young men had been lengthy sleeps since childhood. They seemed to enjoy their sleep, protected it, and were quite concerned when they were occasionally deprived of their desired 9 hours of nightly bed rest. They tended to recall their dreams much better than did the 'short sleepers.'
Many of the 'long sleepers' were shy, anxious, introverted, inhibited, passive, mildly depressed, and unsure of themselves (particularly in social situations). Several openly state that sleep was an escape from their daily problems.

单选题 According to the report, we can infer that ______.

单选题 Many 'short sleepers' are likely to hold the view that ______.

单选题 It is stated in the third paragraph that short sleepers ______.

【正确答案】 B

【答案解析】细节题。短文第三段指出their usual way of dealing with psychological problems was to deny that the problem existed, and then to keep busy in the hope that the trouble would go away. 意为：他们通常处理心理问题的方式是不承认问题的存在，希望只要忙忙碌碌，麻烦总会过去的。由此可知，他们常常忽略这些问题。故答案为B。

单选题 When sometimes they cannot enjoy adequate sleep, the long sleepers might ______.

【正确答案】 A

【答案解析】细节题。短文倒数第二段第三句指出They seemed to enjoy their sleep, protected it, and were quite concerned when they were occasionally deprived of their desired 9 hours of nightly bed rest. 即他们好像注重睡眠，不让睡眠受打搅。偶尔没有所需的9个小时夜间卧床休息，他们便会十分不安。由此可知，答案为A。

单选题 Which of the following is NOT included in the passage?

【正确答案】 B

【答案解析】细节题。短文第四段指出The sleep patterns of the 'short sleepers' were similar to, but less extreme than, sleep patterns shown by many mental patients categorized as manic. 即“睡眠少的人”的睡眠模式与被划入疯子之类精神病患者的睡眠模式十分相似，只不过没有那么严重。故可知选项B不符合原文表达。根据文中When asked to recall their dreams, the 'short sleepers' did poorly. 可知选项A表述正确；根据These men tended to view their nightly periods of unconsciousness as bothersome...以及They seemed to enjoy their sleep...可知两种人对待睡眠的态度截然不同，故选项C表述正确：根据短文第四段“睡眠少的人”的睡眠模式与疯子之类精神病患者的睡眠模式十分相似，由此可判断，“垂眠少的人”应该适当地多睡觉才比较好，因此选项D表述正确，故排除。故选B。
