○

0)have

to的用法情态动词have

to与其他的情态动词can,may,must,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”。eg.You/Heshould

study

hard.你/他应该好好学习。eg.He

hastostudyhard.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

hegowithus?他能和我们一起去吗?He

can't

gowithus.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.Theyhavetogo

the

doctor?Yes,hedoes.Hedoesn'thavetogo

to

the

doctor.者都有“必须”之意但

have

to

表示“客观上的需要”,有人称和时态的变化，否定形式为

don't/doesn't/didn't

have

to(没必要);must

表示“主观上的要求”,无人称和时态的变化，定回答一般用

needn’t或

don't

have

to(不必)。

mustn't表示“禁止”。比一比haveto

与musthave
