At one with nature PPT，第四部分内容：语法精要点拨
“介词＋关系代词”引导的定语从句
此类从句是定语从句中一种介词前置句型，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。
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。
The man to whom you spoke is a teacher.
你同他说话的那个人是一位老师。
The city in which she lives is far away.
她居住的城市很遥远。
The little girl is reading a book，in which there are many cartoons.
小女孩正在读一本书，里面有很多卡通图片。
[名师点津]
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：
The man (who/whom/that)you spoke to is a teacher.
你同他说话的那个人是一位老师。
The city(which/that)she lives in is far away.
她居住的城市很遥远。
[名师点津]
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.
这就是你要找的那支笔。
The patient whom she is looking after is her father.
她正照顾着的病人是她父亲。
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)
我依然记得我来这里的那一天。
(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 house where I lived last year.( in the house＝ where)
这就是我去年住的那所房子。
(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 travelling.(for the reasons ＝why)
人们喜欢旅游有很多原因。
三、关系代词前介词选择三原则：一看先行词，二看动词，三看意义(重中之重)
1．一看先行词，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.
我永远忘不了我来这所学校的那一天。
2．二看动词，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 3，000 yuan.
这就是我花了三千元买的iPad.
3．三看意义，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.
这就是我的那副眼镜，没有它我看不清楚。
