Question

定语从句中表地点的from where 与from which 有什么区别?

Answer 1

都填which,在定语从句中,from which=where,都在从句中担任地点状语的成分.

上面两个句子都是非限制性定语从句,先行词分别是the top of the mountain和the window,在从句中作地点状语,又因为是非限制性定语从句,所以填from which.

上面的句子如果改成限制性定语从句也是对的：

1.He climbed up to the top of the mountain where he could see clearly.

2.He appeared out of the window where the whole city came into view.
