题目内容：

请问老师：He has no house which to live in为什么不对?
看一本语法书上介绍He has no house in which to live是对的,然介词in放后面
He has no house which to live in却不对,为什么不对?

优质解答

He has no house which to live in中不定式的to live in可以直接做house的定语,不定式的宾语就是house,再让which当宾语是多余的；而在He has no house in which to live中,which抢先做了介词in的宾语,那么整个的in which to live这个部分没有多余的宾语,故可以用来做house的定语.
