定语从句特殊用法

定语从句中的特殊用法 定语从句是起定语作用的,修饰,说明名词,代词或句子内容的从句,被定语从句修饰的词叫做先行词。引导定语从句，并在句中担任成分的词叫做关系代词或关系副词。定语从句是高考常考内容之一，使用时要尤其注意以下十种特殊用法。 一、只用that不用which的情况 1、当先行词是all, little, few, much, something,everything, anything, nothing, none等不定代词时。如：Everything that happened then was like a nightmare.当时发生的一切就像是一场噩梦。 I will tell him all that you told me at the ball.我要把你在舞会上跟我说的话全都告诉他。 2、当先行词被only, any, few, little, no, all, just, very（恰好的,表示强调）等词修饰时。例如：The only thing that we could do was to wait.我们能做的只是等待。 That’sthe very thing that we can do.那正是我们能做的事。 3、当先行词是序数词、形容词最高级或先行词被序数词或形容词最高级修饰时。例如：The first place that we visited was the Great Wall.我们参观的第一个地方是长城。 This is the best novel that I have ever read.这是我看过的最好的小说。 4、被修饰词为数词时。例如： Yesterday I caught two fishes and put them in a basin of water. Now you can see the two that are still alive.昨天我捉到了两条鱼，把它们放在一盆水里。你可以看到那两条鱼还活着呢。 5、主句是There be结构，修饰其主语的定语从句宜用that作关系代词修饰物。例句：There’sstill a room that is free.还有一个空房间。

where定语从句特殊用法

Where引导定语从句，先行词不一定都表示地点 1. We will discuss a number of cases __ beginners of English fail to use the language preperly. A.which B.as C.why D.where 2.He was driving so fast as to get himself into a dangerous situation ___he is likely to lose the control over his car. A.which B.as C.why D.where 两道题都选where ，但是case, situation 都不是地点，如何理解？ 在“先行词不是表示地点的名词”的前提下，如何判断是否使用关系副词where来引导定语从句的问题是一个高频考点。就是说，关系副词where所指代的先行词不只是表示地点的名词。 用Where引导定语从句，先行词不一定都表示地点按照通常的理解，当where引导定语从句时，它的先行词就是表示地点的名词，但事实并不是我

们想象的那么简单。很多情况下，where所指代的先行词并不表示地点。请看以下几个例句： 1. Remember that the best relationship is one where your love for each other is greater than your need for each other. 请记住，最深的感情关系表现为彼此间的爱超过彼此间的需要。 点评：这里where引导的定语从句修饰先行词one，也就是relationship (此处one指代的是relationship)。Relationship不是地点名词，但此处却用了where来引导，where在这里表示“在这样的感情关系下”。从定语从句的结构来看，定语从句不缺主语和宾语，引导词where在从句中充当的是状语。 2. Cheating is most likely in situations where the vital interests are high and the chances of getting caught are low. 欺诈行为在这种情况下最有可能发生：利益重大， 而且欺诈行为被发现的可能性小。

定语从句专项知识点总结汇总

定语从句专项知识点总结汇总 - 定语从句(Attributive Clauses)在句中做定语，修饰一个名词或代词，有时也可以修饰部分或整个句子。 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。 关系代词有：who, whom, whose, that, which, as。 关系副词有：when, where, why, how。 关系代词和关系副词放在先行词和定语从句之间，起连接作用，同时又可做定语从句的一个成分。当关系代词做宾语时可以省略。 定语从句中的谓语动词必须在人称上和数量上和先行词保持一致。 定语从句分为限制性定语从句和非限制性定语从句。 1 关系代词引导的定语从句 1) who, whom, that 这些词代替的先行词是人的名词或代词，在从句中所起作用如下：

Is he the man who/that wants to see you? (who/that在从句中作主语) He is the man whom/ that I saw yesterday. (whom/that在从句中作宾语) 2) whose 用来指人或物，(只用作定语，若指物，它还可以同of which互换). 例如： Please pass me the book whose (of which) cover is green. 3) which, that 它们所代替的先行词是事物的名词或代词，在从句中可作主语、宾语等. 例如： A prosperity which / that had never been seen before appears in the countryside. (which / that在句中作宾语) The package (which / that) you are carrying is about to come unwrapped. (which / that在句中作宾语) 关系代词that和which 都可以指物，that 和Who 都可以指人，其用法区别：

as引导定语从句的用法

as引导定语从句的用法 as 引导非限制性定语从句，可放在主句之前，或者主句之后，甚至可以切割一个主句；which 引导的非限制性定语从句只能放在主句之后。另外，as有“正如……，正像……”的意思 (1) As is known to all, China is a developing country. (2) He is from the south, as we can see from his accent. (3) John, as you know, is a famous writer. (4) He has been to Paris more than several times, which I don’t believe. ================================ As 的用法例 1. the same…as；such…as 中的as 是一种固定结构, 和……一样……。 I have got into the same trouble as he (has). 例2. as可引导非限制性从句，常带有'正如'。 As we know, smoking is harmful to one's health. As is known, smoking is harmful to one's health. As是关系代词。例1中的as作know的宾语； 例2中，它充当从句的主语，谓语动词know要用被动式。 一、“as / which”特殊定语从句的先行成分 1. 形容词或形容词短语作先行成分, 具有形容词意义的介词短语也可以充当先行成分，如： My grandmother’s house was a lways of great importance to me, as my own is. 在一定的语言环境里，有些名词可以具有形容词的性质。这些名词主要是那些表示人的身份、职业、状态的名词。值得一提的是，在这些具有形容词性质的名词之后，引导定语从句的关系代词不能用who / whom. 2. 动词短语先行成分。 这种动词短语既可是限定形式也可是非限定形式。如果是动态动词短语，它们在从句中就一般有限定或非限定形式的替代动词do和as / which一起代替。do可以出现，也可以不出现，但不能用其它动词代替。 3. 句子作先行成分。 这句子可以是整个主句也可以只是主句中的一个从句。有时是连续几个句子，有时甚至可以是一个完整的故事。 二、“as/which”特殊定语从句在句中的位置 由于先行成分的构成成分不同，“as/which”特殊定语从句在句中的位置有以下几种情况：1. 形容词做先行成分时：形容词或形容词短语（含具有形容词性质的名词）作先行成分，“as / which”特殊定语从句置于先行成分之后。 2. 动词短语作先行成分时：动词短语作先行成分时，“as / which”特殊定语从句置于先行成分之后。但是，当从句中含有表示主观意志的插入成分时，“as”特殊定语从句可以移至句子之首。 3. 句子作先行成分时：“as”特殊定语从句的位置较灵活，可以置于先行成分之前、之中或之后。但如果先行成分是直接引语，“as”特殊定语从句多在先行成分之前。如果先行成分是否定句，“as”特殊定语从句与否定词的相对位置不同可以使它产生不同的意义。由于“as”特殊定语从句具有这一特点，所以有时它的位置不能随便移动。在非正式的文体里，“which”特殊定语从句可以出现在先行成分之中。

定语从句及其引导词用法

一、基本概念： 在复合句中，修饰某一名词或代词的从句叫定语从句。如： Do you know the man who spoke at the meeting just now? That is the house where he lived ten years ago. 定语从句所修饰的词叫先行词；定语从句一般用关系代词或关系副词来引导，关系词放在先行词与定语从句之间起连接作用，同时又作从句中的一个成分。 引导定语从句的关系代词有：that, who, whom, whose, which; 关系副词有：when, where, why. 二、关系词的用法： （一）关系代词的用法： 1．作主语用who, which和that, 如： He is the man who/that lives next door. The train which/that has just left is for Shenzhen. 2．作宾语用whom, who, which, that, 如： The man (whom/who/that) we have just seen is a famous writer. Where is the book (which/that) I bought last week? 注：在非正式文体中，用于指人的关系代词who whom, that 通常可以省略，但在正式文体中通常用whom, 不可省略；用于指物的关系代词which和that 在非正式文体中也通常省略，但在正式文体中一般不省略。 3．作定语用whose, 如： (a) He is the man whose car was stolen last week. (b) It was a meeting whose importance I did not realize at that time. 注：“whose +名词中心词”这一结构在定语从句中既能作主语（如上a句），又能作宾语（如上b句）。whose 的先行词常用来指人，但有时也可以用来指具体事物或抽象概念，这时可以与of which 结构互换，词序是：“名词+of which”，如： They came to a house whose back wall had broken down.. (= the back wall of which) He’s written a book the name of which I’ve completely forgotten. (= whose name) 4．作表语只用that ，它既可以指人，也可以指物，但时常省略。如： He is no longer the man that he used to be. This is no longer the dirty place (that) it used to be. （二）关系副词的用法： 1．when 指时间，在从句中作时间状语，它的先行词通常有：time, day, morning, night, week, year 等。如： I still remember the time when I first became a college student. Do you know the date when Lincoln was born? 注：when时常可以省略，特别是在某些句型和某些时间状语中。如： Each time he came, he did his best to help us. But help never stopped coming from the day she fell ill. 2．where指地点，在从句中作地点状语。它的先行词通常有：place, spot, street, house, room,

高中英语定语从句精华版教学案

定语从句 思维导图 易考易错点总结 定语从句的用法较为复杂，高考除了单独考查定语从句外，还常常结合句式结构、时态等来综合考查。纵观近年各地高考试题，不难发现其考点主要包括： 1．考查如何正确选择关系词 解题思路：找出从句，确定被修饰词，即先行词→将先行词代入定语从句，判断先行词在定语从句中充当什么成分:若作主语、宾语、表语、定语，则选择关系代词；若作状语则选关系副词。 2．考查whose的用法 whose可以指代人或物，在定语从句中作定语，后跟名词。指物时，whose＋名词＝名词＋of which＝of which＋名词。如：The classroom whose door/the door of which/of which the door is broken is on the second floor. 3．考查as/which引导的非限制性定语从句 尤其要重视which，as引导的非限制性定语从句和that，what引导的主语从句的区别。4．考查定语从句中的主谓一致现象。 如：I, who am your close friend, will try my best to help you whenever you are in trouble. 5．考查“介词＋关系代词”引导的定语从句 “介词＋关系代词”引导的定语从句，关系代词指人时用whom，指物时用which，不能用that。关系代词作定语时也可用whose。 如：The teacher in front of whose house stands a tall tree is very patient with his students. 同时还要注意包含复杂介词或代词短语的定语从句与并列句的区别。 如：(1)He loves his parents deeply, both of whom are very kind to him.(定语从句) (2)He loves his parents deeply and both of them are very kind to him.(并列句)

定语从句用法归纳 篇一：定语从句的用法一、定语从句的有关概念所谓定语从句，就是在复合句中起定语作用以修饰主句中的名词或代词的从句。学习定语从句，首先要弄清两个重要概念——先行词和关系词。先行词是我们汉语中从来没有听过的一个新概念，它其实指的就是被定语从句所修饰的词。由于定语从句修饰名词或代词时，定语从句通常是后置的，所以人们就将放在定语从句前被定语从句修饰的名词或代词叫先行词。 那什么是关系词呢其实它就是用于引导定语从句的引导词。事实上，英语中的各类从句，不管性质如何，它们都需要有一个词来“引导”，正如人们给引导状语从句的词语取了个名字叫从属连词一样，人们也给引导定语从句的词语取了个名字，叫它关系词，因为它通常被放在先行词和定语从句之间起连接作用，以表明两者之间的修饰关系，同时它还在定语从句中充当一定的句子成分。二、定语从句中关系词与所修饰先行词的关系 为了更好地理解定语从句，我们还有必要研究一下关系词与先行词之间的关系。但在研究这种关系之前，我们先来看看关系词有哪些。根据关系词在定语从句中的作用，我们可以将关系词分为关系代词和关系副词两种。所谓关系代词就是指起代词作用的关系词，它们在引导定语从句的同时，还在定语从句中充当主语、宾语、宾语等，英语中比较常用的关系代词有that, which, who, whom, whose等。类似地，关系副词就是指起副词作用的关系词，它们在引导定语从句的同时，还在定语从句中充当状语等，英语中比较常用的关系副词只有三个，即when, where和why。许多初学定语从句的人弄不清关系词与先行词之间到底是什么关系。其实啊，关系词与先行词之间的关系很简单，简单得可以划一个等号。因为，关系词的含义在本质上等价于先行词，它与先行词指的就是同一个人或同一个事物。为便于理解，下面我们来看几个例子吧。I know the man who lives next door. 我认识住在隔壁的那个人。这是一个含有定语从句的复合句。句中的the man为先行词，who lives next door为修饰the man的定语从句；在定语从句中，who是关系词，它在定语从句中用作主语，从意义上说，它在

(完整word版)英语定语从句用法详解

英语定语从句用法详解 在复合句中，修饰名词或代词的从句叫定语从句，被修饰的名词或代词叫先行词，引导定语从句的有关系代词who, whom, whose, which, that等和关系副词where, when, why等，关系代词和关系副词在定语从句中担任句子成份。 1.由who引导的定语从句中，who用作主语，如：This is the boy who often helps me. 2.由whom引导的定语从句中，whom用作宾语，如：The man whom you are waiting for has gone home. 3.由whose引导的定语从句中，whose用作定语，如：Do you know the girl whose skirt is white? 4.由which引导的定语从句中，which用作主语或谓语动词的宾语或介词的宾语，如： The room in which there is a machine is a work shop. The river which is in front of my house is very clean. This is the pen which you want. 注意： (1)whom, which用作介词宾语时，介词可放在whom、which之前，也可放在从句原来的位置上；但在含有介词的动词固定词组中，介词只能放在原来的位置上。如：He is the very person whom we must take good care of. (2)引导非限制性定语从句时，必须用关系代词which，不用that,如：I have lost my bag, which I like very much. (3)关系代词在句中作主语时，从句的谓语动词的人称和数必须和先行词保持一致。 5.由that引导的定语从句中，that可以指人或物，在从句中作主语或谓语动词的宾语，但不能放在介词后面作介词宾语，如： The book that I bought yesterday was written by Lu Xun. 注意在下面几种情况下必须用that引导定语从句。 (1)先行词是不定代词all, few, little, much, something, nothing, anything等，如： All that we have to do is to practise English. (2)先行词被序数词或形容词最高级所修饰，如 The first letter that I got from him will be kept. (3)先行词被all, any, every, each, few, little, no, some等修饰，如 I've eaten up all the food that you gave me. (4)先行词被the only, the very, the same, the last修饰时如 He is the only person that I want to talk with. (5)先行词既有人又有物时，如: They talked about persons and things that they met. (6)当句中已有who时，为避免重复，如：Who is the man that is giving us the class? 6.由when, where, why引导的定语从句，如: I don't know the reason why he was late. This is the place where we have lived for 5 years. I'll never forget the day when I met Mr Li for the first time. 注意：先行词是表示地点时，如果从句的谓语动词是及物的，就用that(which)，如果从句的谓语动词是不及物的，就用where引导。This is the house Which /that he has lived in for 15 years.(Where he has lived for 15 year.)

which引导的定语从句的用法

which引导的定语从句的用法 WHICH可以引导定语从句，修饰表示事物的先行词，在定语从句中充当主语、宾语或者表语。例如：HEWASREADINGABOOK， WHICHWASABOUTWAR.他正在读一本关于战争的书。（关系代词WHICH在修饰BOOK的定语从句中充当主语。） HEWASREADINGABOOK，WHICHHEHADBOUGHTFROMLONDON.他正在读一本书，这本书是从伦敦买回来的。（关系代词WHICH在修饰BOOK的定语从句中充当宾语。） WHICH引导非限定性定语从句时有一个特殊用法，即它所引导的非限定性定语从句修饰主句中更多的部分甚至整个主句（这时被定语从句所修饰的“先行词”要作广义理解），WHICH仍在定语从句中作主语、宾语或表语。例如：HESETFREETHEBIRDSHAPPILY， WHICHWASACELEBRATIONFORHISSUCCESS.他开心地把鸟放了，这是对他成功的一种庆祝。 把非限定性定语从句“WHICHWASACELEBRATIONFORHISSUCCESS”的先行词视为主句中的“THEBIRDS”显然不符合整句的语境，被 “WHICHWASACELEBRATIONFORHISSUCCESS”所修饰的是整个主句，WHICH所引导的这类特殊的非限定性定语从句对主句所叙述的情况进行某种意义的补充说明，WHICH常可译为“这一点，这件事”。 ［考题1］ YOUCANFINDWHATEVERYOUNEEDATTHESHOPPINGCENTRE， ____ISALWAYSBUSYATTHEWEEKEND.（2006上海春） A.THAT B.WHERE C.WHAT D.WHICH ［答案］D
