have 与have to的区别

这题问得真模糊，有没有上下文语境。

have 1 可以做实意动词：I have a dog.
2 也可以做助动词: I have finished it first.
3 或使役动词(相当于make let):I have him do it for me.

have to：做“不得不”讲：I have to do my homework now。我想在不 得不做作业了。

have:
aux. 已经,曾经
n. 吃,从事,得到,雇用,享有,有,允许
v. 有

have to:

必须,不得不

HAVE有多种意思.基本意思有两种.一种是表示拥有.egI have a book一种是做助动词,eg.I has become a teacher.无意义.
have to 是必须的意思.表示情理上的必须.也就是说从内心感到必须做某事.区别于must.must是由于客观不可抗拒的条件所导致的必须.

简单的解释为：

have：有
have to ：不得不

有
不得不

have 有
have done do的完成时
have to不得不
