which引导的定语从句中介词前置
The school which he once studied in is very famous.
= The school in which he once studied is very famous.
第一句话我看得懂,可是第二句介词提前之后,成分我就分析不清了.

Answer 1

第一句和第二句在句意上没有区别,只是介词前置了而已,实际上,无论是第一句还是第二句,which在定语从句中都相当于是状语成分,这里要区分一下,这里所谓的状语是指在定语从句which he once studied in 或者in which he once studied 中的状语,which依然是引导一个定语从句,意思是which he once studied in 或者in which he once studied 是由which引导的定语从句,在主句中充当定于成分修饰the school.那么第一句和第二句的which和介词in合起来相当于where的作用,但是定语从句中是没有where引导的,所以在一些句子中,你认为是用应该是有where即表示地点状语意思的时候,在定语从句中就可以用介词+which来替代!,而介词前置或者介词不前置只是正式和非正式（Formal or Informal）的区别而已,实际上都是在定语从句中充当状语成分.
