中考复习十一 复合句(宾语从句等)(11)

Sleep is very important. A person who does not sleep dies faster than a person who does not eat. We spend about a third（1/3）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 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 an 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 in three Americans has a problem with sleep. Many of these people cannot fall asleep. 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 （醒着）, 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!

答案与解析：

一、单项选择

1.B。本题是考查宾语从句的语序和时态的用法。特殊疑问词引导的宾语从句用陈述语序，主句是一般现在时，宾语从句根据说话人的意思可以判断是一般将来时。所以选择B。

2.A。本题是考查宾语从句的语序用法。特殊疑问词引导的宾语从句用陈述语序，what在宾语从句作主语，所以what is wrong是陈述语序。同样如果D改成is the matter也是正确的。

3.A。本题是考查宾语从句的语序用法，特殊疑问词where引导的宾语从句用陈述语序。从对话的答语可以判断特殊疑问词where引导宾语从句。

4.C。本题是考查反意疑问句的用法。主句是I think和后面的宾语从句构成复合句，其反意疑问句的主语、谓语和宾语从句保持一致，前面的句子是否定句，所以附加疑问句用肯定形式。

5.C。本题是考查反意疑问句的用法。复合句的反意疑问句的主语、谓语和主句保持一致，这里主句是The teacher didn’t say，而且是否定句，所以附加疑问句用肯定形式。

6.C。本题是由while引导的状语从句，强调的是正在进行“看电视”这一动作时，“门铃响了”这一动作也发生了，所以从句用过去进行时，主句用一般过去时。答案为C。

7.A。本题考查表示结果的状语从句，前面一句是说明理由“她很忙”，才产生后面的结
