There is no creature that does not need sleep or complete rest every day.
If you want to know why, just try going without sleep for a long period of time. You will discover that your mind and body would become too tired to work properly. You would become irritable and find it hard to think clearly or concentrate on your work. So sleep is quite simply the time when the cells of your body recover from the work of the day and build up supplies of energy for the next period of activity.
One of the things we all know about sleep is that we are unconscious in sleep. We do not know what is going on around us. But that doesn’ t mean the body stops all activity. The important organs continue to work during sleep, but most of the body functions are slowed down.
For example, our breathing becomes slower and deeper. The heart beats more slowly, and the blood pressure is lower. Our arms and legs become limp(柔软的) and muscles are at rest. It would be impossible for
A. work properly
B. think clearly
C. keep your attention on your work
D. easily get angry
St. Paul didn’t like it. Moses warned his people against it. Hesiod declared it "mischievous" and "hard to get rid of it," but Oscar Wilder said, "Gossip is charming."
"History is merely gossip," he wrote in one of his famous plays. "But scandal is gossip made tedious by morality."
In past time, under Jewish law, gossipmongers might be fined or flogged. The Puritans put them in stocks or ducking stools, but no punishment seemed to have-the desired effect of preventing gossip, which has continued uninterruptedly across the back fences of the centuries.
Today, however, the much-maligned human foible is being looked at in a different light. Psychologists, sociologists, philosophers, even evolutionary biologists are concluding that gossip may not be so bad after all.
Gossip is "an intrinsically valuable activity," philosophy professor Aaron Ben-Ze’ev states in a book he has edited,
A. Everyone involved will not benefit from gossip.
B. Philosophers may hold different attitudes toward-gossip.
C. Dr. Ronald De Sousa regards gossips as perfectly advantageous.
D. People are generally not conscious of the value of medical gossip.
