题目内容

 —I think the man over there must be Bob.

—It ______ be him. He has gone to Paris.

A.can’t            B.can              C.may not           D.mustn’t

 

【答案】

A

【解析】

试题分析:根据 He has gone to Paris.“他去巴黎了。”可知,本句应该是“它不可能是他。”故排除B;“不可能”是can’t。而may not表示“不可以”,mustn’t表示“禁止做”故与题意不符。所以本题选A。

考点:本题考查情态动词的用法。

点评:本题实际是考查情态动词表示推测的情况,这很容易与以前学过的情态动词的用法相混淆。情态动词表示推测的情况,表示一般性推测用might、could表示“可能”;表示肯定推测用must表示“一定”;否定推测用can’t表示“不可能”。

Sleep is very important. A person who does not sleep dies faster than a person who does not eat. We spend about a third()of our lives in 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 of 6 to 12 years of age need an average(平均)of 10 to 12 hours of sleep. Teenagers need 9 to 10 hours of sleep. An adult needs an average of 7 to 8 hours a day. 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 day. We need less sleep as we get older.
About one in three Americans has a problem with sleep. Many of these people cannot fall asleep. The name for 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.

This is not a new problem. Many famous people in history had insomnia. Some of these people had special ideas to make themselves 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!
