B 

　Two experts did some experiments on two groups of people — one who tended to sleep less than the

people around them and the other group more.

According to their 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 automatically began to cut 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 with ambition, active, energetic, cheerful, and conformist (不动摇) in their opinions, and very sure about their career choices. They often held several jobs at once, or even worked full time while going to school. And many of them had a strong urge to appear “acceptable” or “outstanding” 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 them. 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 experts also stated that those “long sleepers” were quite different indeed. They reported that those men had been lengthy sleeps since childhood. They seemed to enjoy their sleep, protected it, and were a bit concerned when they were occasionally deprived of their desired 9 hours of nightly bed rest. They tended to recall their dreams much better than the “short sleepers did.

　　Many of the “long sleepers” were shy, anxious, introverted (内向), inhibited (压抑), passive, mildly depressed, and unsure of themselves (particularly in social situations). Several openly express it that being asleep was a good escape from their daily problems.

All in all, proper time of sleeping should be admired, not too long, neither too short.

According to the report, ______.
