在平时的学习中,说起知识点,应该没有人不熟悉吧?知识点是传递信息的基本单位,知识点对提高学习导航具有重要的作用。相信很多人都在为知识点发愁,下面是小编整理的中考英语定语从句知识点大全,仅供参考,欢迎大家阅读。
中考英语定语从句知识点1
一、定语从句的概念
在复合句中,修饰某一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,引导定语从句的词叫关系词,定语从句一般放在先行词的后面。
二、定语从句的关系词
引导定语从句的关系词有关系代词和关系副词,常见的关系代词包括that, which, who(宾格whom,所有格whose)等,关系副词包括where, when, why等。关系代词和关系副词放在先行词及定语从句之间起连接作用,同时又作定语从句的重要成分。
三、定语从句的分类
根据定语从句与先行词的关系,定语从句可分为限制性定语从句及非限制性定语从句。限制性定语从句紧跟先行词,主句与从句不用逗号分开,从句不可省去。非限制性定语从句与主句之间有逗号分开,起补充说明作用,如省去,意思仍完整。
四、关系代词的用法
1. that 既可以用于指人,也可以用于指物。在从句中作主语、宾语或表语。作主语时不可省略,作宾语可省略。例如:
Mary likes music that is quiet and gentle.
玛丽喜欢轻柔的音乐。(that作主语)

我放在桌子上的那件外套是蓝色的。(that作宾语)

The film (which) we saw last night was wonderful.
我们昨天晚上看的那部电影很好看。(作宾语)
3.who, whom用于指人,who 用作主语,whom用作宾语。在口语中,有时可用who代替whom。who和whom作宾语时也可省略。例如:

Who is the teacher (whom) Li Ming is talking to?
正在与李明谈话的老师是谁?(作宾语)

This is the house in which we lived last year.
这是我们去年居住的房子。
Please tell me from whom you borrowed the English novel.请告诉我你从谁那借的这本英文小说。

中考英语定语从句知识点3
初三都会遇到一个重要语法——定语从句。定语从句是初中语法中较难的一个知识点,同时也是近几年中考必考的,今天我们一起来学习一下定语从句。
形容词,在句中作定语。被定语从句修饰的词叫先行词,定语从句一般放在先行词的后面。引导定语从句的关联词称为关系词,关系词有关系代词和关系副词。关系代词有that, which, who, whom, whose等,绝对没有what;关系副词有where, when, why,how等。关系词放在先行词和定语从句之间,起连接作用,同时又作定语从句的某个成分。
一、关系代词引导的定语从句
1、由who, whom, that,Whose引导的从句
这些词代替的先行词是人的名词或代词,who作主语指人,whom作宾语指人,that既可作主语又可作宾语(作宾语可以省略),可以指人也可以指物。Whose 用来指人或物,只用作定语。
(1) Is he the man who/that wants to see you? 他是那个想见你的男人吗?(who/that在从句中作主语)
(2) 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)
(3) The man whom you spoke to just now is our English teacher 你刚刚说话的那个男人是我们的英语老师
(4) he man whose son is a doctor is our professor. 那个儿子是医生的男人是我们的教授。
2、由which, that引导的从句
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,作宾语时可以省略,例如:
(1) 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在从句中作主语)
(2) The package (which / that) you are carrying is about to come unwrapped. 你拿那个包裹快要散开了。(which / that在从句中作宾语)
注意: 代表物时多用which,但在下列情况中用that而不用which:
a)先行词是anything, everything, nothing , none等不定代词时;
b)先行词由every, any, all, some, no, little, few, much等修饰时,这时的that常被省略;
c)先行词前有序数词或被形容词最高级修饰时;
d)先行词中既有人又有物时;
e)整个句中前面已有which,who,that时;
f)当先行词为物并作表语时;
g)先行词为one时;
h)先行词同时又被the only,the very,the same修饰时;
二、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也可做连接词用
I still remember the day when I first came to the school.
2、where指地点在定语从句中做地点状语
Shanghai is the city where I was born.
3、why指原因在定语从句中做原因状语 ,用在reason 后面。
Please tell me the reason why you missed the plane.
常见考法
对于定语从句的考查,多以单选的形式考查学生灵活运用的能力。一般情况下,常从关系词的意义和功能的角度考查,重点是that,which,who引导的定语从句。
典型例题:You're the only person ______I've ever met ______could do it.
A. who B. whom C. whom D. who
解析:先行词person后有两个定语从句,第一个从句省略了关系代词whom.因为, whom作从句中met的宾语,可以省略.第二个从句who could do it.who在从句中作主语,不可省略.
答案:D
误区提醒
当表示时间或地点的名词作先行词时,要判断出它们在从句中作状语还是主语或宾语。作状语时用关系副词,反之用关系代词。
典型例题:I can never forget the day _______ we worked together and the day ______ we spent together.
A. when; which B. which; when C. what; that D. on which; when
解析:. 两个先行词the day都是表示时间的名词,但第一个空白处要填的关系词在从句中作状语,因此要用关系副词when. 第二个空白处要填的关系词在从句中作动词spent的宾语,因此要用关系代词which或that来引导定语从句.
答案:A
中考英语定语从句知识点4
很多同学可能都会觉得在使用定语从句的时候,有时不知该选择that还是which作为引导词。其实只要记得以下几点,并多做练习,在具体的句子中加以理解,一切问题就可以迎刃而解了。
首先,that和which在从句里都可以做宾语和主语,做宾语时可以省略。在定语从句中,有种说法叫"关宾省",意思是关系代词在限制性定语从句中作宾语可以省略,不管是that,which,还是whom。但是which能引导非限制性定语从句,that则不行。
其次,记得以下只能用that的几种情况:
1. 当先行词为all, much, little, none及由any, every, some, no所构成的复合不定代词时。
如:We should do all that is useful to the people. 我们应该做一切有益于人民的事情。
Please tell me anything that you know about the matter. 有关此事,凡是你所知道的请告诉我。
2. 当先行词被any, few, little, no, all, much, some等词修饰时。
如:You can take any seat that is free. 任何空着的座位你都可以坐。
There is little work that is fit for you. 几乎没有适合你的工作。
3. 当先行词为序数词或被序数词所修饰时。
如:When people talk about the cities of China, the first that comes to my mind is Beijing. 人们谈论起中国的城市的时候,我首先 想到的是北京。
This is the fourth film that has been shown in our school this term. 这是我们校本学期放映的第四部电影。
4. 当先行词为形容词最高级或被形容词最高级修饰时。
如:The best that I could do was to apologize. 我唯一能做的就是赔礼道歉了。
This is the most interesting story book that I have ever read. 这是我读过的一本最有趣的故事书。
5. 当先行词被the very, the only, the last, the just, the same等修饰时。
如: This is the very book that I’m looking for. 这正是我在找的书。
The only thing that we could do was to wait. 我们唯一能做的事就是等待。
注意:先行词被the same修饰时,关系代词也可用as。
如:I need the same book that / as you have. 我需要有你一样的书。
6. 当先行词既包含人又包含物时。
如: They are talking of the heroines and their deeds that interest them. 他们正在谈论他们感兴趣的女英雄及她们的事迹。
7. 当先行词是疑问代词who,which,what或主句以这些词开头时。
如:Who that has ever worked together with him doesn’t admire him? 曾经和他一起工作过的谁不钦佩他?
Which is the star that is nearer to the earth? 哪个是离地球比较近的星星?
8. 当先行词为主句表语或关系代词为从句表语时。
如:That’s a good book that will help you a lot. 那是本对你很有帮助的书。
Our school is no longer the place that it used to be. 我们的学校现在已不是过去的那个样子了。
9. 先行词为time时,当time表示次数,引导词用that, 可省略。 当表示时间,可用that或when引导,都可省略。
如:I do remember the first time(that) I had ever heard the sweetest voice in the world.我很清楚地记得当我第一次听到世界上最美的声音的时候。
中考英语定语从句知识点5
一、前置法
当一个限定性定语从句结构和意义较为简单,或是较为简短时,我们把英语原文的定语从句翻译成带“的”的定语词组,放置于被修饰的词之前,将英语原文的复合句翻译成汉语的简单句。
Furthermore, humans have the ability to modify the environment in which they live, thus subjecting all other life forms to their own peculiar ideas and fancies.(2003)
本句中the environment后面又跟了一个定语从句。大家看下他是什么定语从句,是限定性还是非限定性定语从句。限定性吧!它有什么特点呢,只有三个词,意义和结构都较为简单,因此我们在翻译的时候就要把它放在他所修饰的先行词的前面。
译文:而且,人类还有能力改变自己的生存环境,从而使所有其它形态的生命服从人类自己独特的想法和想像。
But even more important, it was the farthest that scientists had been able to look into the past, for what they were seeing were the patterns and structures that existed 15 billion years ago.(1998,71)
这个句子中That existed 15 billion years ago.是一个定语从句,其先行词是the patterns and structures.这个定语从句比较简单,我们可以直接将其翻译他所修饰的先行词的前面。
译文:但更为重要的是,这是科学家们所能观察到的最遥远的过去的景象,因为他们看到的是150亿年前宇宙云的形状和结构。
二、单独成句
当一个限定性定语从句的结构较为复杂,意义较为繁杂的时候,如果把它翻译在其修饰的先行词的后面的话,会显得定语太过于臃肿和复杂,而无法让评卷老师看的清清楚楚,明明白白。所以这个时候我们要把定语从句单独翻译出来,放置于原来它所修饰的词的后面当定语。同时当定语从句是一个非限定性定语从句的时候,往往也要单独成句。
Tylor defined culture as “...that complex whole which includes belief, art, morals, law, custom, and any other capabilities and habits acquired by man as a member of society.” (2003,64)
在这个句子中,whole后面是一个很长的定语从句,无论从结构和意义上看都较为复杂,所以翻译时可以和先行词拆开。
译文:泰勒把文化定义为“一个复合体”,它包括人作为社会成员所获得的信仰、艺术、道德、法律、风俗以及其它能力和习惯。
The Greeks assumed that the structure of language had some connection with the process of thought, which took root in Europe long before people realized how diverse languages could be.(2004,61)
“which took root in Europe long before people realized how diverse languages could be.”是非限定性定语从句,修饰前面整个句子;在定语从句中long before引导时间状语从句修饰动词短语Take Root,在状语从句中又包含了一个由how引导的宾语从句,作realized的宾语。句中Take root in作“扎根“讲。因此这个非限定性定语从句是较为复杂的,所以我们采用单独成句的翻译方法。
译文:“希腊人认为语言结构与思维过程有着某种关系,这种观点在人们认识到语言的千差万别之前就在欧洲扎了根。”
三、融合法
把主句和定语从句融合成一个简单句,定语从句译成谓语。这种方法一般用于限制性定语从句,尤其是“there be”句型中。
There is a girl downstairs who wants to see you.
楼下有人要见你。
There are many people who are interested in the new invention.
很多人对这项发明感兴趣。
四、状译法
英语中有些定语从句,不仅仅起到一个定语修饰的作用,而且在逻辑上(即意义上)与主句有状语关系,表示原因、让步、转折等等关系。所以广大考生在翻译的时候,应尽量从英语句子的意义上发现这些逻辑上的关系,然后翻译成汉语中相对应的逻辑关系来。
比如:
Actually, it isn't, because it assumes that there is an agreed account of human rights, which is something the world does not have.(1997,71)
在这个句子中which引导非限制性定语从句修饰名词an agreed account,而the world does not have是省略了从句引导词that的定语从句,修饰something。这个定语从句在这里有一个转折的逻辑关系在里边,所以要翻译出来!
译文:事实并非如此,因为这种问法是以人们对人的权利有共同认识为基础的,而这种共同认识并不存在。
名词分类
通常,名词分几类,连词就分几类。引导定语从句的连词大约分为两类:wh-连词和that连词。这两个是决定了几乎所有的定语从句引导词。我们刚才说定语从句的引导词由名词的类别来决定,那我们要先知道名词分为什么。关于名词的分类,我们之前有很多,我们曾经学过名次分为可数名词和不可数名词;专有名词和非专有名词等等。我们知道,连词通常都是指代这个名词的,和指代有关的词,一旦涉及到人的时候,就会变得非常复杂。如果是男的,代词用he;如果是女的,用she;如果指的是说话的对方,用you;如果是自己,用I等等。从这里我们会发现,如果指代的是人,根据指代的不同,所使用的代词也会不同。
因此,第一类词就指的是“由指代人的名词”为先行词的定语从句,那引导词用指人的就行,that是万能的,此外who,whom,whose都可以指人,不过that,who,whom是指人;而whose+名词,表示“谁的...东西”,通常用作定语。
第二大类可以把名词分为“非人”的名词。非人的名词,我们可以把它分为:
①形容没有生命存在的,如桌子,电脑等。指桌子或电脑,只用一个it来代替它就行;
②形容有生命的存在,不管是养什么宠物,如猫、狗等,用it也可以指代了;
③形容比较抽象的感情,如爱情,憎恨,感恩等,it也可以用来指代。
因此,我们可以将代词分为两类:指代人的代词和指代非人的代词。当先行词是不是人的名词的时候,连词可以用which,that,where,when,why,what.
中考英语定语从句知识点6
(一)定语从句一般由关系代词和关系副词引导
1、关系代词:who, whom, whose, which, that, as
2、关系副词:when, where, why
关系代词和关系副词必须位于从句之首,主句先行词之后,起着连接先行词和从句的作用, 同时在从句中又充当句子成分。
e.g. She is the girl who sings best of all.(关系代词who在从句中作主语)
The comrade with whom I came knows French.(whom在从句中作介词with的宾语)
3、关系代词和关系副词的用法:
1)当先行词为人时用who 作主语,whom作宾语;
2)当先行词为物或整个句子时用which ,可作主语或宾语;
3)先行词为人、物时用that ,可作主语或宾语;
4)whose用作定语,可指人或物;
5)关系副词when(指时间,在定语从句中作时间状语,where(指地点,在定语从句中作地点状语),why(指原因,在定语从句中作原因状语)。
(二)限制性定语从句与非限制性定语从句
1、限制性定语从句:从句与主句关系密切,去掉从句,主句意义不完整,甚至不合逻辑。
e.g. I was the only person in our office who was invited.(去掉定语从句,意思就不完整)
2、非限制性定语从句:从句对先行词关系不密切,去掉定从句,意思仍然完整。形式上用逗号隔开,不能that用引导。
e.g. Tom's father, who is over sixty, still works hard day and night.(who引导非限制性定语从句,整个句子可分成两句来翻译)
(三)使用定语从句时特别注意的几个问题
1、that与which的区别。
1)用that而不用 which的情况:
①先行词为不定代词all, anything, nothing, …;
②先行词有最高级修饰,有序数词修饰;
③先行词有only, very, any等词修饰;
④先行词既有人又有物时。
e.g. There is nothing that can prevent him from doing it. 没有什么能阻止他不干那件事。
The first place that they visited in Guilin was Elephant Trunk Hill. 在桂林他们所参观的第一个地方是象鼻山。
This is the best film that I have ever seen. 这部电影是我看过的最好的一部。
Mr Smith is the only foreigner that he knows. 史密斯先生是他认识的唯一的外国人。
2)用which而不用 that的情况:
①引导非限制性定语从句;
②代表整个主句的意思;
③介词 + 关系代词。
e.g. He had failed in the maths exam, which made his father very angry. 他数学考试没有及格,这使他的父亲很生气。
This is the room in which my father lived last year. 这是父亲去年居住过的房子。
3)as引导定语从句时的用法
①as引导限制性定语从句通常用于the same … as, such … as结构中。
e.g. I want the same shirt as my friend's. 我要一件跟我朋友一样的衬衫。
Such machines as are used in our workshop are made in China. 我们车间使用的这种机器是中国制造的。
②as引导非限制性定语从句既可放在主句之前,也可放在主句之后,用来修饰整个句子。通常用下列句型:as is known to all, as is said, as is reported, as is announced, as we all know, as I expect 等。
e.g. As I expected, he got the first place again in this mid-term examination. 正如我所预料的那样,他在这次期中考试中又获得了第一名。
3)as 引导非限制性定语从句时与which的区别
①当主句和从句语义一致时,用as;反之,用which来引导非限制性定语从句。
e.g. He made a long speech, as we expected.
He made a long speech, which was unexpected.
②当非限制定语从句为否定时,常用which引导。
e.g. Tom drinks a lot every day, which his wife doesn't like at all.
2. 关系代词在从句中作主语时,从句的谓语动词单数还是用复数应由先行词决定。
e.g. The man who lives downstairs speaks English fluently. 住在楼下的那个人英语说得很流利。
The students who are in Grade Three are going to climb the hill tomorrow.
3. 定语从句有时不直接紧靠先行词,中间由一个定语、状语或谓语隔开。
e.g. There is an expression in his eyes that I can't understand.
4. 引导定语从句的关系副词有时可以用"介词 + which"来代替。
e.g. October 1, 1949 was the day on which ( = when ) the People's Republic of China was founded.
5. 当定语从句中谓语动词是带介词或副词的固定短语动词时,短语动词的各个固定部分不要拆开。
e.g. The sick man whom she is looking after is her father.
6. 介词在关系代词前,只能用which和whom,且不能省略;介词在句尾,关系代词可有which, that, whom, 口语中也可用who,且可省略。
e.g. The man (whom/ who/ that) you were talking about has come to school.
