高一定语从句里的例如WHICH和介词加WHICH用法到底有什么区别？举几个例子。谢谢

Question

高一定语从句的难点，那个高手会的话讲讲，谢谢了。

Answer 1

which 用于定语从句，作关系代词，在句中要做成分
in which 用于定语从句，作关系副词，在句中不做成分，in which=where

in which 只能用在定语从句中，等于where,在定语从句中作状语。
如：He lived in the house in which Tom once lived.
He lived in the house where Tom once lived.

定语从句中.如
this is the room in which we stayed
先行词是room，后的句子是用来修饰room的
但是room不可做stay的成分，因为stay是不及物动词，后不可直接家宾语
所以要有个介词．
其实上述的句子＝
this is the room which we stayed in．
这里的介词是可以提到which 前的

注意，第二个句子可用that 或省略

但第一个只能用which．只有which前可加介

身边缺书，我可以根据英语书上的大自给你说下，也许有错，偶们也才高一、、试试看定语从句 WHICH可以做关系代词，而介词+WHICH做关系副词，这是个不同点吧！EG：WHICH在从句中作主语或宾语，指物，They planted some trees which didn't need much water.(作主语）The fish (which) we bought tonight were not fresh.(作宾语）介词+WHICH在不同的语境中意思也会有所不同的EG:在从句中作时间状语I'll never forget the time when (=during which) we worked together.Do you remember the afternoon when(=on which) we first met? 在从句中作地点状语EG:This is the place where(=at/in which) we first met?在从句中作原因状语EG:The reason why(=for which) he was late was that he missed his trian.the reason 后跟的一般都是why 吧 貌似~~WHICH和介词加WHICH前者是关系代词 （作主语或宾语）后者是关系副词 （作状语）

which在定语从句中一定+名词in\at which=wherefor which =why I live in the room which you lived in 或者是I live in the room in which you lived . 或I live in the room where you lived 分析： the room 作先行词 用which 后面you lived 一般live in是固定搭配 in放在which前或live后都可以 in which =where
