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.

答
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！

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
