have to和don't need to的意思正好相反。
have to的意思是不得不,后面接动词原形,指受客观条件或环境迫使而"不得不"做某事,突出客观性。don't need to的意思是不需要,和have to的意思正好相反,这里的need是一个实意动词。如:
He had to go to Germany.
他不得不去德国。
He didn't have to go to Germany.
他不必去德国。
We'll have to find a taxi.
我们需要找辆出租车。
We won't need to find a taxi.
我们不需要找辆出租车。
There has to be some kind of way out.
一定会有某种解决办法的。
There doesn't need to be some kind of way out.
不一定会有解决的方法。
That has to be the biggest lie ever told.
那肯定是有史以来最大的谎言。
That doesn't need to be the biggest lie ever told.
那不一定是有史以来最大的谎言。
