定语从句最精准讲解

定语从句

I.定语从句起了 形容词 的作用，在句中修饰一个名词或代词。 I like apples. Apples is red. 两个句子合成一个句子（我喜欢红色的苹果）

被修饰的词叫做先行词，引导定语从句的词叫关系词，关系词的作用：一：连接先行词和定语从句，二是在从句中担当一个成分，并与先行词保持数的一致。

修饰人：

I like the child who/that is kind.

I want to know the boy whom/who/that he is talking to.(此时做talk to 的宾语可以省略)。 修饰物：

I want to buy a book which/that is about English.

II. that与which, who, whom的用法区别：

1. 特别注意：无论什么从句，首先它是一个句子，是句子就最起码要有主语和谓语，或者主语和系动词。

2.定语从句先行词是人或者物的时候选择who/whom/that 很好选择，具体判断就可以。

3. 但是当定语从句的先行词是时间或者地点的名词时，要区分究竟定语从句缺什么成分，如果定语从句主谓(或者主谓宾)成分都有时那定语从句布恩肯定缺的就是状语，选择引导状语的关系词。当定语从句部分主语谓语（或主谓宾成分不全）则在关系代词中选择关系词。

1.The place _______interested me most was the Children's Palace.

2. This is the place ____we visit last summer. A. Which B. where C. what D. in which

4. when/ where/ why 可以用介词加which的形式替换，此时which 不可以换成that。

高中英语定语从句讲解及练习 定语从句是高中重点知识，也是高考常考点，大家也不容易掌握，这篇文章主要教你关系代词引导的定语从句 关系副词引导的定语从句判断关系代词与关系副词限制性和非限制性定语从句等内容，有例题讲解定语从句在句中做定语，修饰一个名词或代词，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。 关系代词有：who, whom, whose, that, which等。 关系副词有：when, where, why等。 18.1 关系代词引导的定语从句 关系代词所代替的先行词是人或物的名词或代词，并在句中充当主语、宾语、定语等成分。关系代词在定语从句中作主语时，从句谓语动词的人称和数要和先行词保持一致。 1）who, whom, that 这些词代替的先行词是人的名词或代词，在从句中作主语和宾语。例如： Is he the man who/that wants to see you? 他就是你想见的人吗？（who/that在从句中作主语） He is the man whom/ that I saw yesterday. 他就是我昨天见的那个人。（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： They rushed over to help the man whose car had broken down.那人车坏了，大家都跑过去帮忙。 Please pass me the book whose （of which）cover is green.请递给我那本绿皮的书。 3）which, that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. 农村出现了前所未有的繁荣。（which / that在句中作宾语） The package （which / that）you are carrying is about to come unwrapped. 你拿的包快散了。（which / that在句中作宾语） 18.2 关系副词引导的定语从句 关系副词可代替的先行词是时间、地点或理由的名词，在从句中作状语。 1）关系副词when, where, why的含义相当于\"介词+ which\"结构，因此常常和\"介词+ which\"结构交替使用。例如： There are occasions when （on which）one must yield.任何人都有不得不屈服的时候。 Beijing is the place where（in which）I was born.北京是我的出生地。 Is this the reason why （for which）he refused our offer?这就是他拒绝我们帮助他的理由吗？ 2）that代替关系副词，可以用于表示时间、地点、方式、理由的名词后取代when, where, why和\"介+which\"引导的定语从句，在口语中that常被省略。例如： His father died the year （that / when / in which）he was born.他父亲在他出生那年逝世了。 He is unlikely to find the place （that / where / in which）he lived forty years ago. 他不大可能找到他四十年前居住过的地方。 18.3 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。及物动词后面无宾语，就必须要求用关系代词；而不及物动词则要求用关系副词。例如： This is the mountain village where I stayed last year. 这是我去年呆过的山村。 I'll never forget the days when I worked together with you.我永远不会忘记与你共事的日子。 判断改错： （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 countryside. 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

高一英语定语从句讲解精华版

定语从句 一、基本概念： 定语： 定语从句： Do you know the man who spoke at the meeting just now That is the house where he lived ten years ago. 引导词：关系词 关系代词有：that, who, whom, whose, which; 在从句中充当： 关系副词有：when, where, why. 在从句充当： 先行词： 定语从句中引关系词的作用： 二、关系词的用法： （一）关系代词的用法： 1． He is the man lives next door. The train has just left is for Shenzhen. 2． The man ________ we have just seen is a famous writer. Where is the book ___________I bought last week （二）关系副词的用法： 1． I still remember the time ________I first became a college student. Do you know the date __________Lincoln was born

(三) 使用关系副词应注意下列几点： 1．这三个关系副词在意义上都相当于一定的介词+which结构： when = on (in, at, during…) + which; where = in (at, on…) + which; why = for which. 如： I was in Beijing on the day when (=on which) he arrived. The office where (=in which) he works is on the third floor. This is the chief reason why (=for which) we did it. 2．当先行词是表时间的time, day等和表地点的place, house等时，一定要注意分析从句的结构，如果缺少主语或宾语时，关系词应该用which或that, 缺少时间状语或地点状语时，才能用when或where，试比较： I’ll never forget the day _________ my hometown was liberated. I’ll never forget the days____________we spent together last summer. His father works in a factory____________radio parts are made. His father works in a factory______________makes radio parts. 三．限制性定语从句与非限制性定语从句 1．限制性定语从句 This is the telegram which he refers to. Is there anything (that) I can do for you 2．非限制性定语从句 This note was left by Tom, who was here a moment ago. As a boy, he was always making things, most of which were electric.

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.

(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.)

定语从句讲解方法

定语从句 定语从句是用来修饰、描述或提供有关名词、代词或整个主句信息的从句。它在整个句子中起形容词的作用。被修饰的名词，语法上称作先行词。从句由关系代词或关系副词引导。关系代词和关系副词不仅起引导定语从句、连接先行词的作用，同时还充当定语从句中的一个成分，如：主语、宾语、介词宾语、表语、定语或状语等。定语从句由下列关系代词和关系副词引导： (1) who, whom, that(2) which, that(3) whose(4) when, Where(5)why 1. 关系代词who，that ,which在从句中修饰、指代人或事物，作主语。 例句: I thank the woman. She helped me. a. b. 例句: Did you hear about the earthquake?

Which 要比that正式一些。 2.关系代词who(whom)，that ,which在从句中修饰、指代人或事物，在从句中作宾语. Whom 是宾格形式，常用于较正式的英语中。who和that,which 常用于口语和非正式的英语中。在口语和非正式英语中更多的情况下，作动词宾语的关系代词常被省略。 例句:The man told me to come back. I saw him in the office. a. b. The man who I saw in the office told me to come back. c. The man that I saw in the office told me to come back. d. The man I saw in the office told me to come back. 我在办公室见到的那为男士叫我回去。 例句: The movie wasn’t very good. wasn’t very good. c. The movie we saw last night wasn’t very goo d. 我们昨晚看的那部电影不怎么样。 关系代词that / which 引导的从句修饰名词The movie。在从句that we saw last night 中，that/ which 作动词saw的宾语。关系代词作动词宾语的时候可以省略。 注意：a. 引导从句的关系代词一定要放在从句的最前面，例如：从句whom I saw in the office，虽然关系代词whom 在句子中作动词的宾语，也应放在从句的最前面。 b. 从句应尽可能地紧跟在所修饰的名词后面。从句whom I saw in the office是用来修饰the man, 所以应放在the man 后面。

高中名词性从句全面讲解及练习(含答案)

高中英语讲义---- 名词性从句（主从、表从、宾从，同从） 1，陈述句做名从用连词that + SV, that 表主句肯定从句完整，不做成分。主从可用it 做形式主语，宾从第一个that 可省略。You study hard. 主从：That you study hard is known to us.= It is known to us that you study hard. 表从：My opinion is that you study hard . 宾从：I think (that) you study hard. …and that (不能省略)…. 同从：My opinion that you study hard is known to us. *比较同从和主从！ 一般抽象名词后对其进行解释和说明的完整句子就是其同位语从句，不完整就是定语从句。 I appreciate your idea that we have an exam every week. （that后完整—同从） $ I appreciate your idea that you came up with last time.（that后不完整---定从） 2，一般问句做名从用连词whether(是否) + SV，whether表主句不肯定从句完整，宾从中可用if（介词后或宾从后有or not时只用whether）。Does your friend like English 主从：Whether your friend likes English isn’t clear .=It isn’t clear whether your friend likes English. 表从：My question is whether your friend likes English. 宾从：I don’t know whether/ if your friend likes English. 同从：My question whether your friend likes English isn’t clear. 3, 特殊问句做名从用疑问词（连词）+ SV, 疑问词做主语时直接+谓语。连接代词（what/which/who/whose…）表主句不肯定从句不完整，连接副词（when/where/why/how）表主句不肯定从句完整。 Where did you go just now ， 主从：Where you went just now isn’t clear.= It isn’t clear where you went just now. 表从：My question is where you went just now. 宾从：I wonder where you went just now. 同从：My question where you went just now isn’t clear. 当主句为现在时态从句时态不受影响，当主句为过去时态从句就应该变成过去的某种时态，但客观真 理总用一般现在时，有固定过去时间总用过去时。 高频考点1，当主从句都缺成分时指物用what/whatever/whichever(有范围), 指人用whoever / whomever(做宾语). The buildings have built in _what_ was farmland. _What_ you need is courage. The prize will be awarded to _whoever_ has won the game. You can choose _what/whatever/whomever_ you like. " Of all, you can choose _whichever_ you like . 2, No matter+疑问词，只能引导让步状语从句（主从句逗号分开），疑问词+ever 既可引导让步状从，又可引导名从（从句在主句中做成分）。
