on which/in which/at which/of which/for which /by which /with which的意思，区别，用法?
你了解这些介词就会用那些从句了与which 无关，你问的就是on in ,at ,of ,for ,by ,with.的区别。 OK
“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 )
for which引导的从句?
定语从句 He is late again，for which he will be punished by the headteacher
why与forwhich有什么区别?
你好O(∩_∩)O~①不可以用for that，因为for 是介词 ，定语从句中that不能和介词连用。②why =for which 表原因，for which 也能是介词前置。why 是关系副词，which是关系代词，英语中有一个规定一般不会在句尾放介词，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。
