Explanation 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。 |
