for which的用法举例?
首先，英语中有一个规定就是一般不会在句尾放介词（介词后面一定有名词）。所以在碰到从句的时候，特别是which或者that所指代的词在从句中视作为介词后面的名词出现的时候，就必须用which，并将介词前置。 which在这里是指代那个the city of Washington的，后面的从句的应该写成the village of Georgetwon was the market center for the city of Washington。 明白了吗？给你举个例子 His first job is in a big bank, from which he learnt a lot of information about financial management. which是指代bank的，后面的从句是说he learnt a lot of information about financial management FROM the BANK. 所以不存在for which的用法，只是介词加which的用法。

in which，for which，on which，at which有什么区别，怎么使用，用法?
in which，for which，on which，at which的区别、使用、用法： 1、in which，for which，on which，at which这些都是定语从句里面，由which引导的定语从句，介词提前。 2、引导定语从句时where与in which有时可互换，有时不能互换，。 3、当“介词+ which”在定语从句中作时间、地点和原因状语时，可以用相应的关系副词when, where和why来替换。 4、where根据情况可以等于in which, at which, on which等。 5、关系副词若要换成“介词+which”只能是for which。
“forwhich”有什么用法?
for which 是介词+which 引导定语从句的结构之一. 介词+which显然与which引导定语从句是不一样的.如： The book in which there are many pictures is mine.这句话中,in which不能改为which.我们将定语从句还原：There are many pictures in the book.(in which= in the book) 又如：Mr.Li’s new house for which he paid ten thousand yuan was burnt down last night.将定语从句还原Mr.Li paid ten thousand yuan for his new house.(for which ＝for his new house )
