　　1. 情态动词“have to”与其他的情态动词如：“can”

　　“may” “must”和 “should” 不同。

　　（1）这4个情态动词没有人称的变化,而have to有。它的第三人称单数为“has to”

　　如：

　　He should study hard.

　　他应该好好学习。

　　He has to study hard.

　　他不得不好好学习。（2）这4个情态动词在一般疑问句中将它们放在句首, 在否定句中直接在他们后边加not即可。

　　我们以can为例:

　　Can he go with us?

　　他能和我们一起去吗？

　　He can’t go with us.

　　他不能和我们一起去。

　　而“have to”要加助动词do , does或

　　did才可能完成其疑问、否定句。

　　试将下面三种话分别写成

　　（1）一般疑问句，并做肯定回答。

　　（2）否定句。

　　a. They have to go to the party.

　　Do they have to go to the party?

　　Yes, they do.

　　They don’t have to go to the party. b. He has to go to see the doctor. Does he have to go to see the doctor? Yes, he does.

　　He doesn’t have to go to see the doctor.

　　c. She had to have a piano lesson yesterday.

　　Did she have to have a piano lesson

　　yesterday?

　　Yes, she did.

　　She didn’t have to have a piano

　　lesson yesterday. 2. I have to help my parents.

　　我不得不帮助我的父母。 help sb. with sth. 或help sb. (to) do sth.

　　上一句我们可以说：

　　I have to help my parents with the

　　housework.

　　或说I have to help my parents (to) do the housework. 3.That’s too bad. Maybe another time.

　　太糟了，也许换个时间吧。

　　或Maybe next time.

　　也许下一次吧。书面表达
