高中英语语法“介词+which/whom”引导的定语从句 “介词+关系代词”引导的定语从句，是定语从句一种介词前置的定语从句句型，介词与关系代词之间 存在一种介宾关系。当关系代词在定语从句中作介词宾语时，把介词置于关系代词前，即演变出“介词+ 关系代词”句型。例如： The man who/whom/th at you spok e to is a teacher. =The man to whom you spok e is a teacher. 一、基本构成 1.“介词+关系代词”结构引导的定语从句中，关系代词只能用which（指物）或whom(指人)，即： 介词+which/whom。 （1）The man to whom you spok e is a teacher. （2）The city in which she lives is far away. （3）The little girl is reading a book,in which there are many cartoons. 注意：当介词放在关系代词的前面时，用在介词后的关系代词不能省略。 2.在限制性定语从句中，当介词置于定语从句的谓语动词之后时，可用that/which(指物)；that/who/whom（指人）作介词的宾语.且此处关系代词可以省略，特别是在口语中。如：（1)The man(who/whom/that)you spok e to is a teacher. （2）The city（which/that）she lives in is far away. 注：通常介词放在定语从句中动词后，也可以放在关系代词前面，但有些特殊动词短语搭配不能拆分，介词只能放在动词后，如：look for,look after,pay attention to,take care of,look forward to,listen to等。This is the pen(that/which)you are looking for. The patient(who/whom/that)she is looking after is her father. The words that/which we should pay attention to are written on the blackboard. There are fifty patients who/whom/that we must take good care of. 二、关系副词when，where，why可用“介词＋which”来代替。关系副词实际上是介词＋先行词。其中 when=表时间的介词（如：in，at,during等）+which； Where=表地点的介词（如：in，at,on,under等）+which； Why=表原因的介词（如：for）+which (1)当先行词表示时间，定语从句中缺少时间状语时，通常用关系副词when引导，此时也可选用表示 时间的介词＋which来代替关系副词when。 I still remember the day when I came here.(on the day=when=on which) (2)当先行词表示地点，定语从句中缺少地点状语时，通常用关系副词where引导，此时也可选用表 示地点的介词＋which来代替关系副词where。 This is the h ou se where I lived last year.(in the house=where=in which) (3)当先行词为reason，定语从句中缺少表示原因状语时，通常用关系副词why引导，此时也可以用 for which来代替关系副词why。 There are many reasons why people like traveling.(for the reasons=why=for which)
