“介词+ which / whom ”引导的定语从句1. 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。
2. 关系词：引导定语从句的关联词称为关系词，关系词有关系代词和关系副词。
关系代词有 that, which, who, whom, whose, as 等；关系畐U词有 where, when, why 等。
3. whose通常指人，也可指物，在定语从句中做定语(1) He has a friend whose father is a doctor.(2) I once lived in a house whose roof has fallen in.(3) The classroom whose door is broken will soon be repaired.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 spoke 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。
如：(1)The man (who/whom /that ) you spoke 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，女口： look for, look after, pay atte ntion to ,take care of ,look forward to, liste n to 等。
This is the pen (that / which) you are look ing 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.练习： Are these sentences right?(1) The man with whom you talked is my friend.(2) The man( who/that) you talked with is my frie nd.(3) The man with who/that you talked is my friend.(4) The pla ne in which we flew to Can ada is very comfortable.(5) The plane in that we flew to Canada is very comfortable.⑹二、关系副词 when , where , why引导的定语从句。
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 whe n引导，此时也可选用表示时间的介词+ which来代替关系副词 when。
例如： I still remember the day when I came here. ( on the day =when)⑵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。
例如： This is the house where I lived last year. ( in the house= where)⑶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。
例如： There are many reasons why people like traveling. (for the reasons =why)三、关系代词前介词选择三原则：一先，二动，三意义(重中之重)1. 一先，即根据定语从句中介词与先行词的搭配关系选择。
I never forget the day on which I came to this school. (on the day)2. 二动，即根据定语从句中谓语动词与介词的搭配关系选择。
This is the iPad on which I spent 3000 yuan. (spend money on sth.)3. 三意义，即根据定语从句的意义来确定介词。
