Are You Getting Enough Sleep?
What happens if you don’t get enough sleep? Randy Gardner, a high school student in the United States, wanted to find out. He designed an experiment on the effects of sleeplessness for a school science project. With doctors watching him carefully, Gardner stayed awake for 264 hours and 12 minutes. That’s eleven days and nights without sleep.
What effect did sleeplessness have on Gardner? After 24 hours without sleep, Gardner started having trouble reading and watching television. The words and pictures were too blurry (模糊). By the third day, he was having trouble doing things with his hands. By the fourth day, Gardner was hallucinating(幻觉). For example, when he saw a feet sign, he thought it was a person. He also imagines he was a famous football player. After the next few days, Gardner’s speech became so slurred(不清楚)that people couldn’t understand him. He also had trouble remembering things. By the eleventh day, Gardner couldn’t pass a counting test. In the middle of the test he simply stopped. He couldn’t remember what he was doing.
Then Gardner finally went to bed, he slept for 14 hours and 45 minutes. The second day he slept twelve hours, the third night he slept for ten and one-half hours, and by the fourth night, he had returned to his normal sleep schedule.
Though Gardner recovered quickly, scientists believe that going without sleep gerous. They say that people should not repeat Randy’s experiment. Tests on Gardner have shown how serious sleeplessness can be. After a few weeks without-started losing their fur(皮毛). And even though the rats ate more food than weight. Eventually the rats died.
During your lifetime, you will probably spend 25 years or more sleeping. But why purpose of sleep? Surprisingly, scientists don’t know for sure. Some sleep in order to replenish(补充)brain cells. Other scientists think body to grow and to relieve stress. Whatever the reason, we know enough sleep.

Exercising Your Memory
1 Aging does not mean a dramatic decline in memory power, unless you help it happen by letting your mind go.
2 That's not to say that memory doesn't change throughout life. Researchers divide memory into categories based on the length of time when memories are stored. One system divides it up as short-term (less than one minute; remembering a telephone number while you dial, for instance), long-term (over a period of years) and very long-term memory (over a lifetime).
3 Short-term memory isn't mastered until about age 7, but after that you never 10se it. Long-term memory, however, involves more effort and skill and changes more through life. It's not until the early teens (十几岁) that most people develop a mature long-term memory.
4 First, we must get information into our heads through learning. Learning strategies can get rusty (生锈) without constant use. High school and college students, who are forced to repeatedly exercise their long-term memory abilities (at least long-term enough to get them through a final exam), usually do well on memory tests. The longer you stay in school, the more chance you get to polish your learning skills. It's no wonder that more highly educated people have more effective memory skills throughout life.
5 Although older people in general learn somewhat more slowly than they did when younger, a dramatic difference exists between those who stay intellectually active m reading, discussing, taking classes, thinking —— and those who do not. Giving the brain daily workout (锻炼) is just as important as exercising your muscles. Brainwork keeps your learning strategies in shape, and this helps your memory to function at full capacity.
6 The next part of a healthy long-term memory is retention (记忆力), the ability to store what you have learned. Memory researchers still do not know whether memories are lost ——whether they still exist in the brain but our mental searching cannot turn them up, or have disappeared entirely as our brain ages.
7 The third necessity for memory is recall, the ability to bring to mind the memories we have stored. Again, while aging has widely different effects on the recall abilities of different people, research indicates that the older we get, the longer it takes to recall facts But slower recall is still recall, in fact, aging does not seem to have any effect on forgetting at all, which takes place at the same rate in younger and older people.
