This is the house where he was born=This is the house in which he was born in =This is the house which he was born in
问题描述：
This is the house where he was born
=This is the house in which he was born in =This is the house which he was born in
答
首先更正下，应该是This is the house in which he was born = This is the house which he was born in
这是定语从句的内容，where 和 which 是引导词，where= in the house, which= the house, in 是介词，表示方位，不是固定搭配，因此放前放后都可以。
答
=This is the house in which he was born.
This is the house which he was born in.这种用法不常见
答
This is the house where he was born=This is the house in which he was born （in 提到前面去了,后面就别在出现了）=This is the house which he was born in （不说 in which 而是把 in 放在后面,也是对的）第一...
