Question

这道题答案为 to control 为什么呀
It is ______breakouts of bird flu that many monitoring stations have been set up, not to disturb the living environment of wildlife.
还有这道题反疑问句为什么用hasn`t he 呀
Johnson knows much about the movie.I think that he must have seen it,____?

Answer 1

to control breakouts of bird flu that many monitoring stations have been set up是动词不定式,做表语,而且跟后面的to disturb the living environment of wildlife对应.
反疑问句是反问从句的内容,而且不可以用情态动词.
