want to的否定是don't want to,而decide +not to do?不都是动词不定式吗?

你说的“动词不定式的否定是加not”是不确切的,应该说情态动词和助动词的否定式加not,实义动词一般加don't,比如你说的want to do的否定式就是don't want to do
回答try to do的否定还是don't try to do,但是你说的try not to do也有这个,但是意思不同,don't try to do我不试着去做,try not to do是“我试着不去做”,意思很明显不同的.
另外,你补充了have to do和want to do是一样的.但是need不同,need在做实义动词时和want他们一样,是don't need to do；但做情态动词时和can他们一样,是needn't.
还有什么继续问哈.

want to的否定是don't want to,而decide +not to do?不都是动词不定式吗? 动词不定式的否定是加not,那want to do? 不定式的否定形式want sb to do的否定形式为don't want sb to do tell sb to do 动词不定式的否定式是在to 前加not,而want to 为什么不能请问1,所有有to do的短语都是动词不定式吗?如decide to do.2,动词不定式一定是 to do形式吗? regret to do want to do这类动词后加to do的是动词短语还是动词不定式英译汉don't want to have you to do anything you do not want to And he does not want to have.Don't want to be nice to him.Do I really don't want to lose Do not 我想知道don't want to do 和want sb not to do 的用法有什么不同 I don't want to hurt others ,also do not want to be hurt .So I don't want to make a wrong ___________(decide)
