①have to通常指由于客观原因则不得不做某事，意思为“不得不”。

一、have to与一般情态动词的异同相同点：一般的情态动词不能单独作谓语，后面必须接动词原形一起构成谓语，have to 也是这样。
不同点：1、一般的情态动词没有人称和数的变化，而且所用的时态也受到一定的限制，而have to 有人称和数的变化。
可用于多种时态中：一般现在时中当主语是第三人称单数时要用has to，其余的人称用have to，一般过去时中要用had to；一般将来时中则要用will have to.e.g. She has to go to school by bus.她不得不乘公汽上学。
You'll have to see the doctor if you get ill.如果你生病了，就得去看医生。
2、否定句和疑问句的构成方式不同：①一般的情态动词直接在后面加not构成否定句，把这些情态动词提到句首就构成一般疑问句。
②而have to 的否定句和疑问句的构成往往要借助于助动词do的适当形式或助动词will即have to, has to, had to和will have to的否定式分别为don't have to, doesn't have to, didn't have to和won't have to，疑问句是在句首加助动词do的相应形式，句中还原成have to或把will放到句首，这里have to简直就是一个十足的行为动词。
