定语从句的引导词问题
以下句子有什么区别：
1.this is the house where he lived last year.
2.this is the house in which he lived in last year.

答案

this is the house where he lived last year.
=.this is the house in which he lived 【没有in】last year.因为in提前了
两句是一样的
先行词【house】在从句中作地点状语
【he lived in the house】所以用where
又因为是【live in the house】,所以where=in which
这种where=介词+which的主要看的是搭配
有不会的可以再问我
