定语从句之二

1、 定语从句之二介词+关系代词引导的定语从句关系代词在定语从句中做介词宾语时从句常由介词+关系代词引导(1) The school (that/which) he once studied in is very famous.(2) The school in which he once studied is very famous.(3) Tomorrow I will bring here a magazine (that/which) you asked for.(4) Tomorrow I will bring here a magazine for which you asked.(5

2、) Well go to hear the famous singer (whom/that/who) we have often talked about.(6) Well go to hear the famous singer about whom we have often talked.注意：1. 含有介词的动词短语 一般不拆开使用，如：look for, look after, take care of等(1) This is the watch which/that I am looking for. (T正确)(2) This is the watch for which I

3、am looking. (F错误)2. 若介词放在关系代词前，关系代词指人时用whom，不可用who或者that；指物时用which，不能用that；关系代词是所有格时用whose(1) The man with whom you talked is my friend. (T)(2) The man with that you talked is my friend. (F)(3) The plane in which we flew to Canada is very comfortable. (T)(4) The plane in that we flew in to Canada is

4、 very comfortable. (F)3. “介词+关系代词”前可有some, any, none, both, all, neither, most, each, few等代词或者数词(1) He loved his parents deeply, both of whom are very kind to him.(2) In the basket there are quite many apples, some of which have gone bad.(3) There are forty students in our class in all, most of whom

5、 are from big cities.关系代词关系代词（一般情况下）that 可用who ,whom 和which在从句做主语，谓语动词的宾语，但是不能做介词的宾语which指物，在从句中作主语，谓语或宾语；who在从句中作主语；whom在从句中宾语；where在从句中修饰表地点的名词，做地点状语；when在从句中通常修饰表时间的名词，做时间状语；why在从句中做原因状语，先行词通常是"reason"有时why也可用for+which代替。例：A doctor is a person who looks after people's health._ _ _ _

6、先行词 主语 谓语 宾语|_|定语从句修饰先行词关系副词引导的定语从句1. when指时间，在定语从句中做时间状语(1) I still remember the day when I first came to the school.(2) The time when we got together finally came.2. where指地点，在定语从句中做地点状语(1) Shanghai is the city where I was born.(2) The house where I lived ten years ago has been pulled down.3. why指

7、原因，在定语从句中做原因状语(1) Please tell me the reason why you missed the plane.(2) I do nt know the reason why he looks unhappy today.注意：关系副词引导的从句可以由“介词+关系代词”引导的从句替换(1) The reason why/ for which he refused the invitation is not clear,(2) From the year when/in which he was going to school he began to know what

8、 he wanted when he grew up.(3) Great changes have taken place in the city in which./where I was born.判断关系代词与关系副词方法一： 用关系代词，还是关系副词完全取决于从句中的谓语动词。不及物动词后面无宾语，就必须要求用关系副词或者是介词加关系代词；而及物动词 后接宾语，则要求用关系代词。例如：This is the mountain village where I stayed last year.I'll never forget the days when I worked tog

9、ether with you.判断改错（注：先显示题，再显示答案，横线；用不同的颜色表示出。）（错） This is the mountain village where I visited last year.（错） I will never forget the days when I spent in the countryside.（对） This is the mountain village (which) I visited last year.（对） I'll never forget the days (which) I spent in the countrysid

10、e.习惯上总把表地点或时间的名词与关系副词 where, when联系在一起。此两题错在关系词的误用上。方法二： 准确判断先行词在定语从句中的成分(主、谓、宾、定、状)，也能正确选择出关系代词/关系副词。例1. Is this museum _ you visited a few days ago?A. whereB. thatC. on whichD. the one例2. Is this the museum _ the exhibition was held?A. whereB. thatC. on whichD. the one答案：例1 D，例2 A例1变为肯定句： This mus

11、eum is _ you visited a few days ago.例2变为肯定句： This is the museum _ the exhibition was held.在句1中，is后应跟表语 ，只有the one可以，而后面的you visited a few days ago则做one的定语从句。而句2中, 主、谓、宾俱全，从句部分为句子的状语表地点，既可用副词where，又因 in the museum词组，可用介词in + which 引导地点状语。而此题中，介词on 用的不对，所以选A。关系词的选择依据在从句中所做的成分，先行词在从句中做主、定、宾语时，选择关系代词 (who, whom, that, which, whose)；先行词在从句中做状语时，应选择关系副词 ( where 地点状语，when 时间状语，why 原因状语) 。编辑本段 |回到顶部 介词+关系词1）介词后面的关系词不能省略。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。This is the house in which I lived two years ago.This is the house where I lived two ye
