Question

this is the right place

定语从句“This is the right place he was born.”为什么句末不可用介词in?

Answer 1

This is the right place（where） he was born.这就是他出生的地方.其中省略了关系副词 where.
用作地点状语的关系副词where通常不能省略,但如果前面遇有place 这一词时,where 则可省略：
This is the place(where) we had our picnic days ago .
这就是我们几天前举行野餐的地方 .
This is the place (where) they met yesterday.
这就是他们昨天碰头的地方.
