情态动词have t与其他的情态动词如can,may,must和shuld 不同。 （1）这4个情态动词没有人称的变化, 而have t有。它的第三人称单数为“has t”。 Yu/He shuld study hard. 你/他应该好好学习。 He has t 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nt即可。
我们以can为例:Can he g with us?他能和我们一起去吗？He can’t g with us.他不能和我们一起去。 而have t要加助动词d , des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 t g t the party. D they have t g t the party? Yes, they d. They dn’t have t g t the party. b. He has t g t see the dctr. Des he have t g t see the dctr? Yes, he des. He desn’t have t g t see the dctr.

have t 与 must
二者都有“必须”之意，但 have t 表示“客观上的需要”，有人称和时态的变化，否定形式为 dn’t / desn’t / didn’t have t (没必要)；must 表示“主观上的要求”，无人称和时态的变化，否定回答一般用 needn’t 或 dn't have t (不必)。mustn’t 表示“禁止”。如：
