题目内容：

saw the house which he lives in 和he is the person who i have ever played with 里面的介词可以提前吗
可以改写成：I saw the house in which he lives 和he is the person with who i have ever played 除些之外,请问还有哪些情况介词可以前置呀?

优质解答

第一句话可以提前
第二句如果提前就要把who--whom.
你要问的是定语从句里面 介词+关系代词（which指代事物 whom指代人） 的结构.
一般的介词的位置提不提前都是可以的.
