doesn't have to和haven't to
因为在新概念65课中有一句‘so it was fortunate that we didn't have to carry him.’当然这句话的意思是,幸运的是我们不必抬起他.可是当我看到didn't have to这种说法时候觉得有点奇怪,但是这是书上写的形式,我想应该是正确的.所以我想知道haven't to是不是不正规的说法,或者说我认为haven't应该只有一个“没有”的意思,不存在haven't to是“不必”的意思.

doesn't have to 是正确的,译为：“不必…………”；
haven't 是完成时的否定形式,不能用haven't to来表示不必做某事

no haven't to
only
have to
don't have to

我来回答哟：
在英语中，如果have 翻译为 “有，拥有”，其后常接名词代词之类的做宾语，它的否定式有两种形式：haven't 或者don't/doesn't have ，这是因为美式英语和英式英语的区别；
have to + 动词原形，其翻译为必须，不得不，因此它的否定式只能是don't/doesn't have to + 动词原形.
问得很好，祝你学习进步、快乐！...
