定语从句介词加关系代词
定语从句介词加关系代词如下：
1、定语从句中的“介词+关系代词”的用法：在“介词+关系代词”结构引导的定语从句中，关系代词指物时用which；指人时用whom，而不能用that或who代替。
例如：There comes the girl, for whom I have been waiting around an hour.这个女孩来了，我将近等了她快一个小时。
2、固定动词短语中的介词通常不能提前，例如listen to/look at/depend on/look for/pay attention to/take care of/look after/take part in/make use of/catch up with/get along with/hear of /look forward to等。
例如：This must be that book that Tom is looking for.这肯定是汤姆正在找的那本书。
3、介词+关系代词的其他用法：
1.复杂介词+关系代词：用于该结构中的关系代词有which/whom/whose。常用的复杂介词有because of/in front of/as a result of/at the back of等。
例如：They were badly hurt in the earthquake, because of which they didn't go to school.
2.表部分或整体的概念的“代词+of+关系代词”：表示部分与整体概念的代词有both/all/neither/none/either/some/any/most/few/half等。
例如：China has lots of nations, one of which is Tujia.这个有许多民族，其中之一为土家族。
3.the+名词+of+关系代词：此结构用于代替whose+名词，也可用“of which the +名词”。
例如：This is the room, the window of which is blue.=This is the room, of which the window is blue.=This is the room whose window is blue.这就是那个窗户为蓝色的房间。
4.关系副词when/where/why可用“介词+which”来代替。
例如：I often think of the moment when/at which I met her.我常常想起见到她的那一刻。
