Explanation
Presentation
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”。
You / He should study hard.
你/他应该好好学习。
He has to study hard.
他不得不好好学习。
have to 的用法
（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。
试将下面三句话分别写成
（1）一般疑问句，并作肯定回答。
（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 study for a math test yesterday.
Did she have to study for a math yesterday?
Yes, she did.

yesterday.
