在定语从句中，关系副词where相当于“from which”还是“in which”？

Question

为什么两种说法都有？

Answer 1

这个要根据后文决定，这里的介词是从句后面从句中的介词前置
with which，for which， in which etc. 都是可以的追问

您好，也就是说要根据从句里的谓语动词的惯用搭配介词来写吗？

这么理解没问题

Answer 2

where=in which
This is the building in which my father works.
=This is the building which my father works in.
介词+关系代词引导的定语从句，介词的选择要能将从句跟先行词连接起来。

您好，Here is Beijing，from which I come. 这里的from which就等于where.

根据前后文判断。比如:
This is the factory where I work. 此时where相当于in which.
It is the prison where the criminal escaped. 此时where相当于from which。
