—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】

試題分析：根據(jù) He has gone to Paris.“他去巴黎了�！笨芍�，本句應(yīng)該是“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”故與題意不符。所以本題選A。

考點(diǎn)：本題考查情態(tài)動(dòng)詞的用法。

點(diǎn)評(píng)：本題實(shí)際是考查情態(tài)動(dòng)詞表示推測(cè)的情況，這很容易與以前學(xué)過的情態(tài)動(dòng)詞的用法相混淆。情態(tài)動(dòng)詞表示推測(cè)的情況，表示一般性推測(cè)用might、could表示“可能”；表示肯定推測(cè)用must表示“一定”；否定推測(cè)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. In the morning, they only remember the time they were awake, 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 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!
