定语从句关系代词选择例句

定语从句关系代词的特殊用法(1) 如果先行词是all, much, anything, something, nothing, everything, little, n one等不定代词，关系代词一般只用that，不用which。

例如：All the people that are present burst into tears.(2) 如果先等词被形容词最高级以及first, last, any, only, few, mush, no, som e, very等词修饰，关系代词常用that,不用which, who，或whom。

例如：(3) 非限制性定语从句中，不能用关系代词that,作宾语用的关系代词也不能省略。

例如：There are about seven million people taking part in the election, most of w hom、are well educated.(4) which还有一种特殊用法，它可以引导从句修饰前面的整个主句，代替主句所表示的整体概念或部分概念。

在这种从句中，which可以作主语，也可以作宾语或表语，多数情况下意思是与and this 相似，并可以指人。

例如：He succeeded in the competition, which made his parents very happy.(5) that可指人或物，在从句中作表语，（指人作主语时多用who）仅用于限制性定语从句中。

(6) which可作表语，既可指人，以可指物。

指人时，一般指从事某种职业或是有种特征．品性或才能的人。

Which引导的定语从句可以限制性的，也可以是非限制性的。

(7) 如果作先作词的集体名词着眼于集体的整体，关系代词用which;若是指集体中的各个成员，则用who。

(8) 先行词有两个，一个指人，一个指物，关系代词应该用that。

例如：The boy and the dog that are in the picture are very lovely.(9) 如果先行词是anyone, anybody, everyone, everybody, someone, somebody,关系代词应该用 who 或whom，不用 which。

四．关系词的选择1．在非限制性定语从句中，关系代词作主语，只能用who 指人，which指物；关系代词做宾语，常用whom（口语中有时用who）指人，which指物，它们都不能用that代替。

2．关系代词作介词宾语，不论是在限制性定语从句中，还是在非限制性定语从句中，当介词前置时，只能用whom指人，which指物；但如果介词后置，则不受这种限制，关系代词还可以省去，特别是在口语中。

如：Do you know the boy to whom she was talking?Do you know the boy (that) she was talking to?The pencil (which/that) he was writing with suddenly broke.3．在限制性定语从句中，当先行词指物时，关系词可用which或that，二者常可以互换；但在下列情况中，只能用that，不用which：(1) 当先行词是all, a lot, (a) little, few, much, none, anything, something, everything, nothing等词时。

如：All that can be done has been done.In this factory I saw little / much that was different from ours.(2) 当先行词被all, any no, much, little, few, every等限定词所修饰时。

如：We heard clearly every word that he said.(3) 当先行词是序数词或被序数词所修饰时。

如：The first thing that should be done is to get the tickets.When people talk about Hangzhou, the first that comes to mind is the West Lake.(4) 当先行词是形容词最高级或被形容词最高级所修饰，以及先行词被序数词和形容词最高级同时修饰时，如：Is that the best that you can do?That’s the most expensive hotel that we’ve ever stayed in.This novel is the second best one that I have ever read.(5) 当先行词被the very, the only, the next, the last等所修饰时。

定语从句语法详解与案例分析定语从句是英语中常用的修饰名词的从句结构，它可以给予读者更多的信息，以便更清晰地描述一个人或事物。

在本文中，我们将对定语从句的语法做详细解释，并提供一些案例分析来加深理解。

一、定语从句的基本结构定语从句的基本结构由引导词（关系词）和从句组成。

引导词根据其在定语从句中的功能和先行词的词性可以分为以下几种：1. 关系代词：who, whom, whose, which, that关系代词在定语从句中作主语、宾语或属格，其选择要根据引导词在定语从句中所充当的成分来确定。

例句1：The girl who is standing there is my sister.例句2：I have a friend whose father is a doctor.例句3：Is there anything that I can do for you?2. 关系副词：where, when, why关系副词分别表示地点、时间和原因，其在定语从句中充当状语。

例句4：I still remember the day when we first met.例句5：This is the place where we used to study.例句6：I don't know the reason why he left.二、定语从句的用法定语从句在句子中的位置可以灵活变化，但通常紧跟在被修饰的名词后面。

1. 限制性定语从句限制性定语从句对名词的修饰是必要的，如果去掉将会使句子的意思不完整或不明确。

关系词可以是关系代词或关系副词。

例句7：The book that I borrowed from the library is very interesting.例句8：He is the man who won the first prize in the competition.2. 非限制性定语从句非限制性定语从句对名词的修饰是附加的，可以去掉而不影响句子的基本意思。

定语从句与关系代词的关系及例句分析定语从句是英语语法中的一个重要概念，用于修饰一个名词或代词，并且由关系代词引导。

关系代词在句中起到连接主句和从句的作用，同时也充当从句中的一个成分。

本文将详细探讨定语从句与关系代词的关系，并通过分析例句来进一步理解和应用。

一、定语从句的定义及作用定语从句是由一个名词或代词引导的从句，用来修饰先行词，并且对其进行补充说明或限定。

在定语从句中，关系代词充当句子的一个成分，起到连接主句和从句的作用。

定语从句的引导词常常包括who, whom, whose, which, that等。

定语从句的作用主要有以下几个方面：1. 为先行词提供详细信息。

例如，在句子"The girl who is wearing a blue dress is my sister."中，定语从句"who is wearing a blue dress"提供了关于姑娘所穿颜色的详细信息。

2. 对先行词进行限定或区分。

例如，在句子"The book that I borrowed from the library is very interesting."中，定语从句"that I borrowed from the library"限定了被借的书籍的特定性。

3. 扩展句子的信息并增强句子的表达力。

例如，在句子"The car, which is red, belongs to my brother."中，定语从句"which is red"增加了对车辆颜色的描述，使得句子更加生动。

二、关系代词在定语从句中的应用关系代词在定语从句中既起到连接作用，又在从句中充当一个成分。

根据在从句中充当的角色和先行词的属性，关系代词的选择有所差异。

1. 关系代词"who"和"whom"关系代词"who"和"whom"用于修饰人，并且在从句中充当主语或宾语的角色。

定语从句例句定语从句例句（一）：关系代词在定语从句中，能作关系代词的有whowhom、which、that。

(1)whothat指人例：He is the man whothat lives next door.他是住在隔壁的那个人。

注意：关系代词在从句中作宾语时，whichthat坚持不变，who变为whom。

例：We wondered whom the book was about. 我们想明白这本书是关于谁的。

(2)whichthat指物例：The book whichthat you borrowed me yesterdayis interesting. 你昨日借给我的书很有意思。

定语从句例句（二）：关系副词在定语从句中，能作关系副词的有why（表原因）、where（表地点）、when（表时光）。

例：This is the reason why I was late this morning. 这就是我今日早上迟到的原因。

This is the town where he was born.这是他出生的小镇。

Tom got married in 2000 when he was 24 years old. 2000年汤姆结婚了，当时他24岁。

注意：千万不要看见前面是原因、地点、时光就用why、where、when这些关系副词，关键要看它们在从句中起名词还是副词的作用。

请看下头的例题：This is the reason ______ I was late this morning.This is the reason ______ I told you.第一句中，the reason用来修饰迟到这个动词，表示早上迟到的原因（I was late because…），所以它起到副词的作用，要用why。

而第二句中，the reason 是told的宾语（I told you the reason），起名词的作用，所以要用whichthat。

定语从句中关系代词之要点一、在下列情况下不能使用关系代词：thatA、如关系代词前有介词时：1、He is not the person about whom we talked yesterday.2、Is this the restaurant in which you work?B、如在非限制性定语从句中：1、The man , who is talking with my mother ,is my headmaster.2、The book , which was lost yesterday, cost twenty yuan.C、先行词本身是that 时：The clock is that which tells the time.二、在下列情况下一般都使用关系代词：thatA、先行词为下列不定代词：all , few , little , much , everything , something , anything , nothing , the one1、All is not gold that glitters.2、All is well that ends well.3、Everything that can be done should be done.4、He told me all that he knew.5、Is there anything that I can do for you?6、Nothing that he does is badly done.7、Is this factory the one that you want to visit?B、先行词既指人又指物：They talked about the things and persons that they remembered in the school.C、先行词被序数词或形容词最高级：1、The first lesson that I learned will never be forgotten.2、This is the largest bridge that has been built.D、先行词被下列词不定代词修饰：all any every few little no some none much one of1、I have read all the books that you gave me.2、Is there any question that troubles you much?3、Little is done that is helpful to our work.4、All the money that was accepted has already been spent on food and clothing.E、先行词被下列词修饰：the only the very the same the last1 、He is the only person that I want to talk to .2、He was the very one of the students that was praised at the meeting.3、The last place that we visited in the countryside was a farm.注意以下难点：1、先行词为way 时，关系代词一般省略，间或使用that, in which但不能用how.1)I don’t like the way (that/ in which) you laugh at him.2)I like the way (that / in which) he talks and laughs.2、先行词为time , day , moment , 时，关系代词一般省略,间或使用that (=when) 但不能使用when.1)Each time I go there ,I always find him watching TV at home.2)By the time he was fourteen years old, he had learned maths all by himself.3)The moment I saw him, he was successful.特别注意以下定语从句：It’s high ( about ) time that we had (should have) supper.(虚拟语气)It’s the first time (that) I have been here. 定语从句3、先行词为reason 时，有时省略关系代词，有时使用that (=for which, why)I like the place for the very reason that (for which , why ) you dislike it.4、有时but 可作关系代词，此时but = who / which… not ….There is no one but wishes peace.= There is no one who doesn’t wish peace.5、先行词为the same , such 修饰时，一般采用固定词组as1.I have bought the same bicycle as you have.2.This is the same watch as I lost.

定语从句一、定语从句的定义在句子中起定语作用、修饰句中的某一名词或代词的从句为定语从句，被修饰的名词或代词叫作先行词，可以代表人、物或者全句。

定语从句由关系代词和关系副词引导。

关系代词：who, whom, whose, which, that, as关系副词：when, where, why关系代词和关系副词在从句中充当一个语法成分。

例如：This is the book that my father bought me yesterday.The time when he arrives is unknown.二、关系词引导的定语从句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、表语或定语等成分。

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。

⑴指人的关系代词who, whom, whose, that的用法。

①作主语(who / that)The man who / that is talking with Mr. Wang is a famous doctor.②作宾语包括作介词宾语(whom / that)。

定语从句中关系代词如何选择初中的一个难点就是怎么选择定语从句中的关系词，也对于同学们理解文章和句子的意思有很大的帮助，那么下面小编就来总结一下。

1.定语从句：定语从句就是在句中作定语，修饰和限定名词或者代词。

被修饰的这个词叫做先行词，连接先行词和定语从句的词叫做关系词。

eg：The girl that i spoke to is my cousion.(和我说话的那个女孩是我的表妹。

)这个句子中的先行词是The girl,关系代词是that,定语从句中的主语是i,谓语动词是spoke.2.关系代词关系词就是连接先行词和定语从句的词，代替从句中缺少的主语或者宾语。

分为关系代词和关系副词。

常见的关系代词有：that, which,whom, who, whos。

充当宾语的有：that, which,whom。

充当主语的有：that，which,who。

充当定语的有：whose。

3.那么我们如何选择关系代词呢？首先，确定先行词是人还是物，其次，确定定语从句中缺少的成分。

如果先行词是人，可选择who, whom, whose 或that。

先行词是人,定语从句中缺少主语时用：that,who；先行词是人，定语从句中缺少宾语时用：that,who，whom（可以省略）；先行词是人,定语从句中缺少定语时用：whose(.....的)。

4.如果先行词是物，可选择which，that，whose 。

先行词是物,定语从句中缺少主语时用：which，tha；先行词是物,定语从句中缺少宾语时用：which，that（可以省略）；先行词是物,定语从句中缺少定语时用：whose（=of which）。

但，当关系代词前有介词时，只用which,而且不能省略。

总结：选择定语从句中关系代词时，首先，确定先行词是人还是物，其次，确定定语从句中缺少的成分。

定语从句之关系代词用法（II）引导定语从句的关系代词有：who、whom（指人）、which（指物）、that、whose （人物双指）。

其各自用法如下：一、who、whom及whosewho、whom、whose作为关系代词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，其先行词主要指人，其中whose也可指物。

关系代词在定语从句中作主语时用who，作宾语或表语时用whom或who，表示所属关系时用whose。

1．、．who和whom的区别：不能用whom在从句中作主语，只能作宾语或表语。

而who作主语、宾语、表语均可。

例如：a) The girl who we supposed was drowned came back.= The girl who , we supposed , was drowned came back.b) The girl who/whom we supposed drowned came back.(2)whom在作动词或介词宾语时，特别是在口语中，一般省去，或用who、that 代替。

而在以介词结尾的定语从句中最好不用whom。

例如：a) I think you should stay faithful to the person whom you're married to . (×)上面一句一般被认为是不正确的，宜改为：b) I think you should stay faithful to the person who/that you’re married to .(口语中)c) I think you should stay faithful to the person you’re married to .d) I think you should stay faithful to the person to whom you’re married .(正式文体中)（３）在非限制性定语从句中，最好whom用作宾语，且不能省略。

定语从句例句定语从句是英语中一种常见的复合句结构，用来修饰名词或代词，进一步描述或限定其所指的人或物。

定语从句通常由关系代词（如who, whom, whose, which, that等）引导，也可以由关系副词（如where, when, why等）引导。
