不是,是情态动词
1 have to的用法
I have to get up early tomorrow morning.
我明天早晨必须(不得不)早起.
1.have(has)to +动词原形
have(has)to后面要用动词原形.当主语为第三人称单数时用has to~,当句子是过去时用had to~.
We have to leave now.
我们不得不现在就离开.
He has to work on Sunday.
他不得不在周日工作.
I had to do my homework last Sunday.
上周日,我不得不做作业.
2 have to的否定句
句型:主语+don''t(doesn''t)have to+动词原形~.
You don''t have to walk so fast.
你不必走那么快.
He will not have to buy a new coat next year.
明年,他没必要买新外衣了.
3 have to的疑问句
句型:Do(Does)+主语+have to +动词原形~
Do you have to study maths now?
你现在必须学数字吗?
Yes,I do.是的,必须学.
No,I don''t(have to).不,不必学.
Did he have to ask the question?
他非要问那个问题吗?
Yes,he did.是的.
No,he didn''t(have to).不.
不能那么说,在这里have和to构成的是一个故有意思的词组,要加一起才有它的意思,have在这里没有实际的意思!
