高考英语“介词+关系代词”引导的定语从句常见错误透视 专题辅导
高考英语“介词+关系代词〞引导的定语从句常见错误透视我们在学习定语从句时,常常会看到"介词+关系代词"引导的定语从句,即把从句中的某一介词或介词短语提到关系代词前.使用这类定语从句时,常常会出现五类错误.现在归纳如下,供同学们借鉴.一、关系词的误用1. The person to who you should write is Mr Hall. (whom)2. I lost the book in that there are five color pictures. (which)3. The day on when we can send men into space has at last come. (which)4. He went back to the house in where he was born twenty years ago. (which)简析:当介词位于从句的句首时,介词后一般用关系代词whom(指人,如1不可为who所代替)或which(指物,如 2.先行词即使为表示时间或地点的名词,介词后也不能用when或where,如3和4).不过,注意介词from有时根据句意的枰?也可以接where.如:He hid himself behind the door, from where he saw the man take a photo of something on the desk.他躲在门后面,从那里他看见那个人拍摄了桌子上的什么东西一下.(指from behind the door"从门后面",并非指from the door"从门")二、拆开从句中极固定的动词搭配5. He was the boy after whom the woman had looked for many years. (whom the woman had looked after for many years)简析:假设将定语从句中搭配极为固定的短语中的介词提前,其中的短语可能会失去它们本身的意义或可能使句子产生歧义,如look after, look for, depend on, go in for (迷恋)等短语.三、介词与定语从句所修饰的先行词搭配不当6. The farm in which we worked ten years ago isn't what it used to be. (on)7. She wanted to find the way with which she could make everyone live more happily. (in)简析:6. on the farm为习惯搭配,表示"在农场";7. in与way搭配,表示"用……方法,以……方式".四、介词与定语从句中的谓语局部搭配不当8. In the dark street, there wasn't a single person from whom she could turn for help. (to)9. This is the tree in which the boat was tied. (to)10. Can you find an object with which your toy is similar? (to)简析:8. turn to sb. for help表示"向某人求助";9. tie与to连用,表示"拴/系到……上";10. similar与to搭配,表示"与……相似".五、介词与句子的具体含义搭配不当11. I can't remember the age in which I won that prize. (at)12. That is the age at which people live in peace and happy. (in)简析:根据全句意义,11中的age作"年岁"解,应与at搭配;12中的age表示"时期,时代",应与in搭配.。

高中英语引导定语从句-介词+关系代词结构归纳
引导定语从句的“ 介词+ 关系代词” 结构在英语中，由“介词+关系代词”引导的限制性和非限制性定语从句十分常见。
但是，不少人在阅读和翻译时对此结构往往感到困惑。
以下从五个方面对此结构进行探讨。
一．“介词+ 关系代词” 结构中的关系代词用来引导定语从句的关系代词常见的有who，whom，whose，which，that等。
而这些关系代词能在定语从句中作宾语的只有whom，which和that三个。
这三个关系代词也能在从句中作介词的宾语，但是，that作介词宾语时，介词不可放在that之前，只能放在从句中原来的位置上，因此，“介词+关系代词”结构中的关系代词实际上只有whom和which两个。
例如:The two things about which Marx was not sure were the grammar and some of the idioms.马克思不大有把握的两方面是语法和某些习惯语。
He had a bad cold, because of which he didn't attend the meeting.他得了重感冒，因此而未能参加会议。
There are 30 students in our class，of whom 25 are league members.我们班里有学生30人，其中25人是团员。
The person to whom I spoke just now is the postmaster.我刚才跟他讲话的那个人是邮政局局长。
有时，我们可以见到“介词+where"引导定语从句的例子。
例如:His head soon appeared out of one of the second storey windows，from where he could see nothing but trees.他的头很快从二楼的一个窗口外显露出来，从那儿，除了树木他什么也看不见。
(完整版)“介词+关系代词”中介词的确定方法
一行二动三意义纵观10年来各地高考试题对定语从句的考查，越来越突出能力立意，通过一系列的增元、减员，前置等变换手段来考查.定语从句中关于“介词+关系代词”引导定语从句时介词的选择则更是令众多考生十分头疼的一大难题。
之所以难，主要在于难以选出合适的介词。
应对“介词+关系代词”中介词如何选则这一难题，笔者根据教学经验,总结出一套行之有效的秘诀:“一先二动三意义”.一、一先,即先杀先行词。
从先行词下手。
介词往往和先行词构成固定搭配。
杀题背景：当先行词往往是那些表示时间、地点、原因、方法、工具等的词时,它们与介词之间有一定的固定联系，多用这种方法。
(比如时间常和on; in、by搭配，地点常用on; in; at，原因用for，方式用in； by; with等等) eg： The pencil _____C__he used to write is broken。
A. in which B. by which C。
with which D。
with that解题:考的是“介词+关系代词”结构，关系代词指物的话用which,指人whom，先把D选项排除了。
剩下这三项选择哪个呢？我们先从先行词下手，pencil是工具范畴,介词搭配一般用with，选择C。
【牛刀小试】Many people who had seen the film were afraid to go to the forest when they remembered the scenes ___A___ people were eaten by the tiger. (2005广东卷） A。
in which B. by which C. which 解题：when 引导时间状语从句“在那个情景中，人被老虎吃掉"。
先行词scene情景，场合，属于“时间，地点”类型的词。
符合我们杀题三部曲之第一部曲的杀题背景。
我们说在情景中，在场合下，搭配的介词是in ，in the scenes 选择A .二、杀题第二部曲-———二动。
定语从句中介词加关系代词的用法
定语从句中介词加关系代词的用法定语从句是指用来修饰名词或代词的从句，在英语语法中有丰富多样的用法。
其中，当介词与关系代词相结合时，就构成了定语从句中介词加关系代词的用法。
在这种结构中，介词在定语从句中起到特定的作用，而关系代词则在从句中充当连接词。
常用的关系代词有：who, whom, whose, which, that。
介词在定语从句中主要有以下几种情况的用法。
1. 介词+关系代词在从句中作宾语时，介词可以放在关系代词之前或之后。
例如：- The book which I am looking for is on the table.- The book for which I am looking is on the table.2. 介词+关系代词在从句中作宾语时，如果介词是短语动词的一部分，介词只能放在关系代词之后。
例如：- That is the man whom I am talking about.- That is the man about whom I am talking.3. 介词+关系代词在从句中作定语时，关系代词的选择要根据介词的要求而定。
例如：- The book on which I am working is very challenging.- The house in which she lives is beautiful.4. 当关系代词是物格形式（whom），介词可以前置到关系代词之前。
例如：- The person to whom I gave the book is my friend.- The person whom I gave the book to is my friend.需要注意的是，在口语中，人们往往更倾向于使用介词后置的形式，即将介词放在关系代词后面。
同时，有时候可以使用介词+which来替代介词+关系代词的结构，这种形式更加简洁。

定语从句中介词+关系词的用法
介词＋关系代词”引导定语从句是我们学习定语从句的重点，也是高考的常考点。
学习这种从句应注意以下几点：1. 用于这种情况的关系代词一般为which（指物）和whom（指人）。
在这种结构中，介词的选择非常关键，可以遵循以下四个原则：（1）根据定语从句中的谓语动词确定介词，其动词与介词搭配，构成动词短语。
例如：Is this the car for which you paid a high price? （pay for）这是你花大价钱买的车吗？I n the dark street, there wasn’t a single person to whom she could turn for help. （turn to sb. for help）在黑暗的街上，她找不到一个人来帮助她。
The man with whom you shook hands just now is our English teacher. （shake hands with sb. ）刚才你和他握手的那个人是我们的英语老师。
（2）根据定语从句中的形容词确定介词，其形容词与介词搭配，构成形容词短语。
例如：The two things about which Karl Marx was not sure were the grammar and some of the idioms. （be sure about）马克思没有把握的两件事是：语法和习惯用法。
The teacher with whom the students in our class are popular is Mr Wang, our English teacher. （be popular with）在我们班，深受学生欢迎的是王老师－－我们的英语老师。
（3）根据定语从句修饰的先行词确定介词，其先行词往往是表示时间、地点、原因、方法、工具等的词，它们与介词之间有一定的联系。
关系代词前介词的选择
关系代词前介词的选择作者：于志芬来源：《高中生·高考指导》2012年第08期在“介词+关系代词”引导的定语从句中，关系代词主要有which，whom，whose，它们既可以引导限制性定语从句，也可以引导非限制性定语从句。
我们应如何选择关系代词前的介词呢？一、介词与从句的先行词是习惯搭配当先行词为时间名词或地点名词（该名词在主句中可充当主语、宾语、补足语、表语或者同位语等）时，我们应根据定语从句所修饰的名词前习惯搭配的介词来确定关系代词前的介词，此时的“介词+which”相当于when或where，在从句中作时间状语或地点状语。
该定语从句既可以是限制性的，也可以是非限制性的。
最常见的表示时间的介词有in，at，on，during，since，by，before，after，until等。
如：例1 Do you remember the day you joined our club？A. on whichB. of whichC. by whichD. at which解析：答案为A。
先行词the day常与on搭配，构成介词短语on the day，在从句中作时间状语，所以用on which引导定语从句。
二、介词与从句的谓语动词是习惯搭配当定语从句的谓语动词为含有介词的动词短语，且先行词在从句中作介词的宾语时，该介词可以移到关系代词之前，构成“介词+which/whom”引导的定语从句。
在含有介词的短语动词中，由于动词和介词的关系比较紧密，一般不能将介词与动词拆开，也不能将介词提到关系代词之前。
这类短语动词有listen to/look at/depend on/take care of/look into/break into/get rid of/look forward to等。
如：例2 Gun control is a subject Americans have argued for a long time.A. of whichB. with whichC. about whichD. at which解析：答案为C。
高考英语考点 68介词+关系代词引导的定语从句
考点六十八介词+关系代词引导的定语从句●＂介词＋关系代词＂的用法当关系代词在定语从句中作介词宾语时，我们通常用＂介词＋关系代词＂引导定语从句。
如果指＂人＂，用＂介词＋whom＂；如果指＂物＂，用＂介词＋which＂。
●＂介词＋关系代词＂结构中介词的选用1.一般来说，确定关系代词前的介词，可以从以下三方面入手：①先行词的意义；②从句中的动词或形容词与先行词的固定搭配；③句子的意思。
☞I’ll never forget the time during which I spent my childhood in the country.我永远不会忘记孩童时代我在乡村度过的时光。
2.表示＂整体和部分关系＂，介词常用of。
在some，any，few，none，all，both，neither，most，each等代词或数词的前、后可以用of which/whom。
☞John invited about 40 people to his wedding，most of whom are family members.约翰邀请了大约40人参加他的婚礼，他们当中绝大部分是家庭成员。
3.有时＂介词＋where＂可以引导定语从句，此时要和＂介词＋which＂引导的定语从句从意思上加以区别。
☞His head soon appeared out of the window，from where he saw nothing but trees.他的头很快从窗口探了出来，从那里除了树木他什么也看不到。
(from where相当于from out of the window，而不是from the window)●在定语从句中，含介词的短语动词不可拆开使用(短语拆开后含义发生变化)，如look after, look for等。
●＂of which / whom＂有时可以用＂whose＋名词＂结构来改写。
●当先行词为way并且定语从句中缺少状语时，通常用in which或that引导定语从句(in which 或that可省略)；如果定语从句中不缺少状语，则用关系代词引导(that 或which 可省略)。

定语从句中介词加关系代词的用法
“介词+关系词”的用法1、关系代词在从句中作介词的宾语时，介词常可以提前，但介词提前时，关系代词只能用which 或whom。

关系副词when, where, why可以用适当的介词+which来替代。

如：when=in/on/at…+which, where=in/on/at…+which, why=for+which如：I won’t forget the date when( on which) I was born.This is the room where (in which) I lived. = This is the room which I lived in.I don’t know the reason why (for which) he hasn’t come today.Tom still remembers the days when (in which) they lived in Tianjin.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等如：This is the watch which/that I am looking for. (√)This is the watch for which I am looking. (F)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如：The man with whom you talked is my friend. (√)The man who/that you talked with is my friend. (F)The plane in which we flew to Canada is very comfortable. (√)The plane in that we flew in to Canada is very comfortable.

2. 关系副词“when”：- 用于修饰时间，在从句中作时间状语。
- 在非限制性定语从句中，通常用“at which”代替。
三、定语从句的句型：1. “介词+关系代词/关系副词”：- 介词可以是“in”，“on”，“with”等等，关系代词或关系副词用来引导定语从句。
2. “先行词+关系代词+不定式”：- 先行词常为不定代词，如“something”，“anything”，“nothing”等等，关系代词用来引导定语从句。
3. “as”的使用：- 当先行词是“such”，“the same”，“so”等修饰词时，可以用“as”作为关系词引导定语从句。
以上是定语从句的引导词和句型的归纳总结。
怎样判断定语从句
怎样判断定语从句定语从句在句中作定语，修饰名词或代词，被修饰的名词词组或代词即先行词。
定语从句通常出现在先行词之后，由关系词(关系代词或关系副词)引出。
那么怎样判断定语从句?下面我们去了解一下吧!怎样判断定语从句一、定语从句的识别：名词(句子)+连接词+句子其中识别度最高的关键之处，就是连接词，它有三种：① 关系代词：who, whom, that, which, as, whose② 关系副词：when, where, why, how③ 介词+关系代词：介词+whom, 介词+which, 介词+whose但注意，有时你会看到 in that，但in that=because，算是一种固定搭配，这和定语从句没关系。
这里单独说一下as引导的定语从句吧，因为其它都还比较常见，as相对来说比较生疏。
主要是在same和such之后，定语从句用as引导，但偶尔the same后面也用that.如：I've never heard such stories as he tells.我从来没听到过他讲的这种故事。
He is wearing the same suit as(或that) he wore at Mary's wedding.他穿着与他在玛丽的婚礼上穿的一样的衣服。
二、定语从句的处理原则：将定语从句完整地切分出来，独立成句。
两个关键点：① 完整地切分;② 独立成句第一步，切分：切分点在连接词前，如果连接词前有介词那就在介词前。
如：I love this girl / who is beautiful.I went to Changchun / where I met my wife for the first time.I have three books / of which the red is my favorite.第二步，找指代(也就是关系代词的指代对象)：如：This is the expert / to whom we are turning.注：turn to = resort to = 求助于……这句话里的关系代词是 whom , 它的指代对象是the expert.所以这句话翻译过来是：这就是我们正在求助的那个专家。
