问题描述:

反意疑问句It's impossible for the small boy to reach the top of the hill,___ ___?
It's impossible for the small boy to reach the top of the hill,___ ___?
书上答案写的是is it
个人认为impossible只是个形容词并没有否定意义.
因为我在书上已经发现了一些答案有错误,所以怀疑这题的答案应该是isn't it
请各位英语帝解说下谢谢=w=

It's impossible for the small boy to reach the top of the hill,__isn't_ __it_?
你的观点是对的.书上的答案错了.记住,反义词不是否定词,反义词只是某个词的反义词,在语法上它具有肯定的概念.
又如:You dislike his idea,don't you?(这里不能用-----do you?).
