那些单词虽然后面接动词不定式,但是否定式在前面动词前加don't(doesn;t,didn't)比如I want to be an actor.不写I want not to be an actor.写I don'tvwant to be an actor.
问题描述:
那些单词虽然后面接动词不定式,但是否定式在前面动词前加don't(doesn;t,didn't)
比如I want to be an actor.
不写I want not to be an actor.
写I don'tvwant to be an actor.
答
因为英语里的否定式就是要加助动词do构成的,和后面接不接动词不定式没有关系。
否定式是否定谓语动词,动词不定式不是谓语动词。
答
这个问题其实很简单:
1 如果你是要是否定整个句子,就在动词前面加助动词.
2 如果你是要否定不定式的动作,就在不定式符号to前面加not.
3 有些否定转移的动词像think,believe,suppose,imagine,expect等后面接宾语从句,要对从句进行否定,该否定应移至主句,即否定主句的这些谓语动词.
I don't think it will rain tomorrow.
We don't expect our football team will win the World Cup.
