好像动词不定式否定 是 在不定式之前加not,构成not to do sth.
如:tell sb not to do sth
但 want to do sth 就是直接用 don't want to do sth
怎么回事?
答
want sb not to do
help sb not to do
一个是句子的否定,一个是不定式的否定形式
答
want to do sth 直接用 don't want to do sth 这里的不定式是做宾语的tell sb not to do sth 这里的不定式是做宾语补足语的!结构不同.实例:I don't want to do that. I want him not to do that.当然第二句也...
