Question

Sleep is very important. A person who does not sleep dies faster than a person who does not eat. We spend about one-third(三分之一) of our lives on sleep. That’s about 121 days a year!

How much sleep do we need? We are all different. A baby needs 16 hours of sleep every day. Children 6 to 12 years old need an average(平均) of 10 to 12 hours of sleep. Teenagers need 9 to 10 hours of sleep. An adult needs all average of 7 to 8 hours a night. There are some people who need only 3 hours of sleep. Others need 10 hours of sleep. After the age of 50, the average sleep time goes down to 6.5 hours a night. We need less sleep as we get older.

About one one-third Americans has a problem with sleep. Many of these people cannot fall asleep(睡著). The name of this problem is insomnia. Some people say, “I didn’t sleep all night.” But that’s not really true. They may sleep lightly and wake up several times. In the morning, they only remember the times they were awake(醒著), so they think they were awake all night.

This is not a new problem. Many famous people in history had insomnia. Some of these people had special ideas to make them sleep. Benjamin Franklin had four beds. He moved from one to the other to fall asleep. Mark Twain had a different way. He lay on his side across the end of the bed.

【解析】

試題分析：這篇短文主要介紹了睡眠是非常重要的。我們的一生中的三分之一都是在睡眠中度過(guò)的。每一個(gè)成年人大約需要七八個(gè)小時(shí)的睡眠。現(xiàn)在睡眠問(wèn)題困擾著許多的人。

1.We spend about one-third(三分之一) of our lives on sleep.一年的三分之一是四個(gè)月，故選B。

2.Teenagers need 9 to 10 hours of sleep.知選C

3.細(xì)節(jié)理解題。根據(jù)Many of these people cannot fall asleep.知選A

4.】是非判斷題。A選項(xiàng)可以在第一段的第二句可以否定掉。A person who does not sleep dies faster than a person who does not eat.B選項(xiàng)可以在第二段的最后一句找到出處。We need less sleep as we get older.C選項(xiàng)文章沒(méi)有提到這個(gè)概念。D選項(xiàng)犯了以偏概全的錯(cuò)誤，D選項(xiàng)的論調(diào)只說(shuō)明本杰明.富蘭克林使這樣的，而馬克吐溫并不是這樣的。.故選B

5.全文來(lái)看，A、C和D項(xiàng)都不全面，只有B最全面，故選B。
