请教各位一道关于从句的问题

来源：百度知道 编辑：UC知道 时间：2024/05/27 07:02:07
for which ; at which ; in which ; on which 分别是什么用法呢?
它们是在定语从句里出现还是在宾语从句里出现呀?
我还是不太明白
这个介词加在哪里怎么看....

这要看具体的句子,一般是看从句中的动词词组或介词短语.
如:1.This is the bus for which we are waiting.
2.The watch at which he is looking is very
expensive.
3.We visited Shanghai in whitch I was born
4.Yesterday was February 15 on which my aunt
went to Beijing.

which前面用什么是由你后面的从句来决定的，并不是硬套的
从句内容决定用for就是for which，你可以先把for给改的后面的从句里面看一下就知道什么意思了。

在定语从句中出现.
