Question

在定语从句中，由介词＋which/whom引导的定语从句中的介词依据什么而定？？？

Answer 1

介词选择要根据从句的动词来定
eg: I don't know the person with whom you talked just now. 我不认识刚才和你讲话的人。此处从句为 talk with sb. 和某人交谈。用talk with
I don't know the person about whom you talked just now.我不认识你刚才谈论到的那个人。此句中为talk about sb. 谈论某人。 用talk about
当先行词是物的时候用which是，也是考虑从句动词与先行词的搭配
eg. could you find the bus by which you get here.
could you find the bus in/on which you saw the fight.

Answer 2

所引导从句中的不及物动词的词组搭配，也就是该词与修饰词的关系。

Answer 3

先行词 which 一般用在物.whom 一般用在宾语后头

Answer 4

一般来说有两个依据

追答

1，依据被修饰的名词前面所需要的介词
2，依据定语从句中的谓语动词所需要的介词

如：This the house in which Lu Xun once lived
这里的介词in就是依据house来定的，在房子里，当然用in

This is a picture at which you just looked

这里的介词at就是依据定从中谓语动词look，看照片要用look at the picture

Answer 5

应该是句末的动词
