2020高中英语语法：介词加关系代词引导的定语从句

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)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 spent3000yuan.(spend money on sth.)3.三意义，即根据定语从句的意义来确定介词。

This is my pair of glasses,without which_I cannot see clearly.例题：用“介词+关系代词”的形式表示1.Do you like the book__________she learned a lot?2.He paid the boy$10for washing ten windows,most______hadn't been cleaned for at least a year.3.The tower_________people can have a good view is on the hill.注意：介词+关系代词1）介词后面的关系代词不能省略。

2）that前不能有介词。

3）某些在从句中充当时间，地点或原因状语的"介词+关系词"结构可以同关系副词when,where和why互换。

四、“介词+关系代词”前还可有some,any,none,all,both,neither,many,most,each,few等代词或者数词。

构成：some,any,none,all,both,neither,many,most,each,few+o f+whom(人）/which(物）He loves his parents deeply,both of whom are very kind to him.他深深地爱着他的父母，他们俩待他都很好。
