定语从句的from where怎么用？

Question

如题所述

Answer 1

定语从句中，当先行词指物时，只有介词+which,没有from where的用法，当指地点时介词+which= where，当不能既用介词又用关系副词where。

1.He climbed up to the top of the mountain, from _which___ (which/ where) he could see clearly.

因为此句中的先行词是the top of the mountain，指物，且放在介词from之后，所以用which，from which = where。

2.He appeared out of the window, from _which______ (where/which)the whole city came into view.

先行词rhe window。 理由同第一题。
