问题描述:

have to 的否定形式
是haven't to 还是don't have to .它们有什么区别~

只有don't have to
他们的区别就是一个是错的一个是对的

haven't to

haven't to:不需要……

没有什么区别 关键在于现在普遍接受的是哪个
应该是第二种形式的。

don't have to
have to (不得不)是一个词组,have 在这里不做谓语~~
所以不是haven't to

don't have to,根本没有haven't to !

not have to

一般都用don't have to

只有don't have to的用法,没有haven't to的用法。

DO NOT HAVE TO

在我们这里,人们都说:
don't have to
do not have to
没有听说过: haven't to
