回答(1):

这主要是因为英语的动词词组分为两种:动词短语和短语动词。动词短语是可以把介词提前和动词分开的,词组意思不变,如learn from:lily is the girl from whom we should learn.
还有一类短语动词,介词是不能和动词分开的,否则词组意思改变,这时候介词就不能提前。如this is the man who we are looking for.
注意:介词提前时,定语从句的引导词只能用 which, whom, whose,而不能用that或who。

因为关系代词在从句中做介词宾语,所以前面要加介词,以“介词+关系代词”的形式来引导从句,如:
This is the school in which I studied two years ago.
但有些是固定搭配,如look for,look at,take care of等,如:
The book which I am looking for.
