情态动词用法和练习(3)

情态动词用法

只要将情态动词移到主语(Subject)的前面，句尾加上问号。这样就成了疑问句。

1. She can work. (主语she, 情态动词 can，动词 work)

Can she work ? (这就是疑问句）

2. He would be working. (主语he, 情态动词 would，动词 be working) Would he be working ?

3. They should have worked. (主语they, 情态动词should, 动词have worked)

Should they have worked ?

4. I could have been working. (主语 I, 情态动词 could, 动词 have been working)

Could I have been working ?

三、情态动词的否定句：

在情态动词的后面加上 not 就成了情态动词否定句。

1. She can work.

She cannot work. (注意：can 和 not 须连在一起）(这就是否定句)

2. He would be working.

He would not be working. (would not)

3. They should have worked.

They should not have worked. (should not)

4. I could have been working.

I could not have been working. (could not)
