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（产生幻
觉）.For example,when he saw a street sign,he thought it was a person.He also imagined he was a famous
football player. Over 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 counting.He couldn't remember what he
was doing.
When Gardner finally went to bed,he slept for 14 hours and 45 minutes.The second night he slept for
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.
Even though Gardner recovered quickly,scientists believe that going without sleep can be dangerous.
They say that people should not repeat Randy's experiment. Tests on white rats have shown how serious
sleeplessness can be. After a few weeks without sleep, the rats started losing their fur（皮毛）.And even
though the rats ate more food than usual,they lost weight.Eventually the rats died.
During your lifetime,you will probably spend 25 years or more sleeping.But why?What is the purpose
of sleep? Surprisingly,scientists don't know for sure.Some scientists think we sleep in order to
replenish（补充）brain cells. Other scientists think that sleep helps the body to grow and to relieve stress.
Whatever the reason,we know that it is important to get enough sleep.

Going without sleep is not dangerous for white rats.

参考答案
参考解析
解析：由文章第一段第三句可知Randy Gardner是在做不睡觉的实验而不是研究睡眠过多的问题。
由第一段最后一句可知，Gardner有11个夜晚没有睡觉，而不是每晚睡两个小时。
由第二段中“became so slurred that people couldn't understand him”可知他说话不清楚，人们都听不懂他说的话。
由第三段最后一句中的“by the fourth night...”可知，到了第四天，Gardner恢复了正常的睡眠状态。
由第四段可知，老鼠不睡觉会导致脱毛、多食、失重甚至死亡等危险，故此观点错误。
由最后一段第四句可知，科学家也不确定人们为什么要睡觉。
文中并没有提到人们与以前相比睡得少了还是睡得多了的问题。第3部分：概括大意与完成句子
