初中英语定语从句知识点总结

初中英语定语从句知识点总结一、定语从句的定义定语从句是英语语法中的重要组成部分，它是一个句子作为定语修饰一个名词或代词的成分。

定语从句通常用于描述、限制被修饰的名词或代词，进一步说明该词的用途、性质、特征等。

二、定语从句的分类根据定语从句与被修饰词的关系，可以分为限制性定语从句和非限制性定语从句。

限制性定语从句对被修饰词的内涵进行限制，没有它则意思不完整；非限制性定语从句是对被修饰词的补充说明，起到一种附加说明的作用，如果去掉，意思仍然完整。

三、定语从句的关系词关系词是连接定语从句和主句的纽带，关系词包括that、which、who、whom、as等。

它们在定语从句中充当一定的成分，并且可以替代先行词。

1. that：既可以作为关系代词，也可以作为副词。

在从句中作主语、宾语或表语，指人或事物。

作主语时，谓语动词为人称代词，如：The girl that I like is standing over there.（我喜欢的女孩正在那站着。

）作宾语时，可省略。

作表语时，多用于there be结构之后。

2. which：作为关系代词，在定语从句中作主语或宾语，指物。

可以引导限制性定语从句和非限制性定语从句。

如：This is the book which I bought yesterday.（这就是我昨天买的书。

）3. who/whom：作为关系代词，在定语从句中作主语或宾语。

指人。

who在从句中做主语，whom在从句中做宾语。

如：The teacher who is standing there is my English teacher.（站在那的老师是我的英语老师。

）4. as：作为关系代词，在定语从句中作主语、宾语或表语，既可指人也可指物。

例如：He is an artist as we all know.（他是一位我们大家都知道的艺术家。

）四、定语从句的用法1. 限制性定语从句通常紧跟在被修饰词之后，有逗号隔开。

定语从句知识点汇总

定语从句◆英语谚语欣赏1. He who knows nothing but pretends to know everything is indeed a good-for –nothing.不懂装懂;一事无成.2. It’s the first step that costs.千里之行;始于足下3. He that makes himself a sheep shall be eaten by the wolf. 甘当小绵羊;迟早要喂狼.Ⅰ. 概念：1 定语从句：在主从复合句中用作定语的从句叫定语从句..定语从句一般紧接在先行词antecedent后面..2 先行词：被定语从句修饰的成份..先行词可以为一个词;短语;或整个主句..3 引导定语从句的词叫关系词;分为关系代词和关系副词..关系词的作用：1 引导定语从句;连接主句和从句;相当于一个连词；2 必在从句中作某个句子成份可以做主语;宾语;表语;定语;状语常用的关系代词: that、 which、 who、whom、whose、as常用的关系副词在从句中只作状语: when、why、 whereThe student who answered the question was John.I know the reason why he was so angry.The boy whom you are talking to is my brother.I'd like a room whose window looks out over the sea.定语从句三步：第一找出先行词；第二看先行词在定语从句中的语法功能做主语、宾语或状语；第三选择合适的关系词..Ⅱ. 几个关系代词的基本用法：●that: 可指人或物；在定语从句中作主语;宾语;表语..指人时;相当于who或whom；指物时;相当于which一般不用于非限制性定语从句; 不可置于介词后作宾语如：1. A letter that/which is written in pencil is difficult to read. 主语2. Do you know the gentleman that/who spoke just now3. You can take anything that you like. 宾语4. What is the question that/which they are talking about5. Here is the man who/whom/that you want to see.6. She's no longer the girl that she used to be before.表语7. Our hometown is no longer the one that it used to be.= Our hometown is not the same as it used to be.= Our hometown is different from what it used to be..= Our hometown is not what it used to be.●which: 指物；在定语从句中作主语;宾语;表语;定语..如：1. The book which/that was on the desk was bought by my father.主语2. The book which/that I bought yesterday is very interesting.宾语3. The factory in which his father works is far from here.4. He was proud; which his brother never was. 表语5. Tom spent four years in college; during which time he learned French.定语6. He may be late; in which case we ought to wait for him.●who; whom; whose:who: 主格; 在从句中作主语;在口语或非正式用法中作宾语; 只可指人whom: 宾格;在从句中作宾语; 只可指人whose: 属格;在从句中作定语;可指人也可指物..I like the students who/that work hard. 主语All who heard the story were amazed. 代词如he; they; any; those; all; one 等后多用who.Chaplin; for whom life had once been very hard; was a success as an actor. 宾语He's a man from whom we should learn.= He's a man whom/who/that we should learn from.A child whose parents are dead is called an orphan.指人I'd like a room whose window faces south. 指物=I'd like a room of which the window faces south.=I'd like a room the window of which faces south.There is a teapot shaped like a Chinese duck; out of whose mouth tea is supposed to come1.关系代词 whose;引导时;既可指人;又可指物;在从句中只能作定语；of whom 只能指人；of which 只能指物;有时 whose 可以与 of whom 和 of which 互换使用..如：The girl whose hair is golden is from England. 头发金色的那个女孩是英国人..The house whose doors are green is an office building. 门是绿色的那座房子是办公楼..2.“介词 + whose +名词” 引导..如：I love my motherland; for whose good future I will work hard. 我爱我的祖国;为了她美好的未来我要努力工作..3.在下列情况下;一般只用 of whom 和 of which..1的主语是 few; little; some; most; many; much等时;一般只用of whom和of which..In the room are lots of people; many of whom I don’t know. 房间里有很多人;很多人我不认识..He has a lot of story-books; a few of which I have never read. 他有很多故事书;有几本故事书我还从未看过..2定语从句的主语是数词、形容词的最高级时;一般只用of whom和of which..如：The old man has three children; two of whom are college students and one of whom is a manager. 那个老人有三个小孩;其中两个是大学生;另一个是经理.. 3的主语是all; none; both; neither; each等不定代词时;一般只用of whom和of which..如：There are fifty students in our class; all of whom are working hard. 我们班有五十个学生;所有这五十个学生学习都刻苦..He planted two trees last year; both of which are growing well. 去年他栽了两棵树;这两棵树都长得好..4在中作表语的定语时;一般只用of whom和of which..如：He has three brothers; of whom Li Lei is the youngest one. 它有三兄弟;李蕾是他们中最小的一个..There are many countries in Asia; of which China is the largest one. 亚洲有很多国家;中国是最大的一个..关系代词作介词宾语:关系代词在定语从句中用作介词宾语时; 介词可放于从句之首; 也可放于从句之末. 但以放于句首较为正式.介词前置;必须注意不影响动词词组的含义..关系代词who 和 that 用作介词宾语时; 介词必须放在句末.关系代词前介词选择三原则：一先;二动;三意义重中之重1.一先;即根据定语从句中介词与先行词的搭配关系选择..I never forget the day on which I came to this school. on the day2. 二动;即根据定语从句中谓语动词与介词的搭配关系选择..This is the iPad on which I spent 3000 yuan. spend money on sth.3. 三意义;即根据定语从句的意义来确定介词..This is my pair of glasses; without which I cannot see clearly.This is the book for which you asked.=This is the book that/which you asked for.Do you know the person with whom I shook hands = Do you know the person whom/who/that I shook hands withThe beginning of agriculture was a big step in human progress with which nothing could compare until our information age.In the dark street; there wasn't a single person to whom she could turn for help.Is this the factory to which you paid a visit last weekIs this factory the one to which you paid a visit last weekThis is the girl whom they are looking after.介词after与look构成固定词组;不可前置..look at; look for; look after; take care of; hearof\about\from; care for; look forward; pay attention to; listen to等●as 的用法:as 引导定语从句; 在定语从句中作主语、宾语、表语①如为限制性的;多用于the same …as ; the same as；such …as …; as many/much as；so …as等结构中..如：※I have the same book as you have. 我有一本和你的一样的书..Her attitude to him was quite the same as it had always been. 关系代词as和指示代词same连用; 在从句中用作表语; 先行词是same..---Why didn't you mention that in face of the police just now--- I thought it was such a minor detail as was hardly worth mentioning. We will only discuss such problems as have something to do with our own interests.Don't do such things as you are not sure about.There is no such place as you dream of in all this world.比较：I live in the same house that he used to live in.I'm wearing the same shirt as you wore yesterday.比较：Here is so big a stone as no one can lift. 定语从句Here is so big a stone that no one can lift it.结果状语从句②如为非限制性的;多单独引导一个定语从句;这种定语从句可置于句首;句中或句尾;译为"正如;这一点"..动词常为know; see; expect; point out; etc.As we all know; smoking is harmful to one's health . as 作宾语=As is known to all; smoking is harmful to one's health . as 作主语=It's known to all that smoking is harmful to one's health .=Smoking is harmful to one's health ; as we all know .as 作宾语=Smoking; as we all know; is harmful to one' health.He was a foreigner; as I knew from his accent. 宾语; 先行词是前面整个句子Ⅲ. 关系副词引导的定语从句:●When 指时间;在定语从句中作时间状语..其先行词是表时间的名词如：time; day; week; tear; month; etc.He came last night when I was out.We will put off the picnic until next week; when the weather would be better.注意：先行词为"时间名词";可用when引导定语从句;when在定语从句中作状语；还可以用which或that 引导;which或that在从句中作主语或宾语..比较: I still remember the day when /on which my brother joined the army.作状语Next month; when you will be in your hometown; is just around the corner.I still remember the days which/that we spent together. 作宾语Next winter which/that you'll spend in Harbin; I'm sure; will be exciting.I shall never forget the day when Shen Zhou Ⅴ was launched; which has a great effect on my life.There are occasions when joking is not permissible.●Where 指地点;在定语从句中作地点状语..其先行词是表示地点的名词;如：place; school; factory; room; etc.This is the place where I was born.I live in the room where /in which he used to live.注意：先行词是"地点名词";定语从句可用where引导;还可用which或that引导;which/that 在从句中作主语或宾语..比较: ※This is the factory where /in which he worked last year. 作状语在高中的英语学习中;我们都知道;where在定语从句中用作关系副词;作状语;先行词一般指地点..例如：This is the farm where we worked when we were young.这就是我们年轻时候在此干活的农场..He met his wife in the park where they fell in love with each other.他是在这个公园遇到他的妻子;就是在那里;他们相爱了..当然;在实际的英语学习中;where在定语从句中的用法远不是这么简单;相反;要复杂得多;为了让学生对where在定语从句中的用法有更好的了解;下面我就对学生在学习过程中的重难点问题谈一谈它的用法..一、某些在从句中充当地点状语的“介词+关系词”结构可以与where 互换;where=in/at/on/...which例如：This is the house in which I lived two years ago.这是我两年前住过的房子..This is the house where I lived two years ago.在英语学习中;并不是单纯地让学生知道where的这种用法就可以了;很多时候学生要掌握where和其他词的用法的区别;才能更好地把握定语从句的用法..例如：This is the factory where/in which you worked last year.This is the factory that/which/you visited last year.在第一句中;关系词在定语从句中作状语;所以用关系副词where或者in which;因为定语从句中worked 是个不及物动词；而在第二句中;关系词在定语从句中做宾语;因此用that或which;还可以省略;visited是个及物动词..学生有时还会碰到更复杂的情况..例如：Is this factory the one that/which/\ you visited last yearIs this factory the one where/in which you lived last yearIs this the factory where/in which you lived last year 这几个句子比前面的两个句子又复杂;除了要区别关系词在定语句子作什么成分;还要注意到前两个句子缺成分;所以要补充 the one..二、where定语从句修饰抽象名词where引导的定语从句的先行词大多数情况下是表示地点的名词;但也有特殊情况..如果定语从句修饰point;situation;part;condition和case等表示抽象意义的词;关系词在定语从句中充当状语时;常用where 引导;意思是“到了某种地步;在某种境况中” ..为了帮助同学们熟悉这一语言现象;正确掌握这一知识点;对where定语从句修饰抽象名词的用法作一归纳..1 where定语从句修饰抽象名词pointYou reach a point where medicine can’t help.你已到了药物无法治疗的地步..We have reached a point where a change is needed.我们到了必须改一改的地步..注：有时point也可以是具体的地点：The accident happened at the point where the A15 joins the M1. 事故发生在A15与M1交叉的十字路口..2 where定语从句修饰抽象名词caseThere are cases where the word “mighty” is used as an adverb. 在一些情况下;mighty一词可用作副词..3 where定语从句修饰抽象名词activityThose successful deaf dancers think that dancing is an activity where sight matters more than hearing.那些失聪的成功舞蹈演员们认为;舞蹈是一种让人看胜过让人听的活动..4 where定语从句修饰抽象名词situationHe got into a situation where it is hard to decide what is right and wrong. 他陷入一种难以分辨是非的局面..5 where定语从句修饰抽象名词positionIt’s put me in a position where I can’t afford to take the job. 这使我陷入一种不能接受此工作的境地..6 where定语从句修饰抽象名词jobShe wants a job where her management skills can be put to good use. 她想找一份能将她的管理技能派上用场的工作..当然了;我们碰到这些词作为先行词时并不一定都用where;我们也要具体情况具体分析;他们只有在定语从句中作状语时才用where..例如：We are trying to reach a point ____ both sides will sit down together and talk.A. whichB. thatC. whereD. when---Do you have anything to say for yourself---Yes; there’s one point ____ we must insist on.A. whyB. whereC. howD. /上面两个句子虽然先行词相同;都是point;但是由于他们在定语从句中充当的成分不同;所以我们在选择关系词时就要区别对待..第一个句子中关系词在句中作状语;所以选择where关系副词；第二个句子中关系词在定语从句中做宾语;所以选择关系代词that;which或者不填;这样第一题选择C;第二题选择D..The treatment will continue until the patient reaches the point where he can walk correctly and safely.I think you have got to the point where a change is needed; or you would fail.Government reports; legal papers and most business letters are the main situations where English is used.He's got himself into a dangerous situation where he's likely to lose control of the plane.The small mountain village where we spent our holiday last month lies in what /the place which is now part of Hubei.This is the park which/that they visited last year. 作宾语Not having been there before; he simply had no idea about the place; which everyone says is worth visiting.●Why 指原因;在定语从句中作原因状语..先行词为reason 时;可用for which指代；当关系词在从句中作主语或宾语时;则用which或that 引导..如：The reason why / for which / that he didn't attend the meeting was that he was ill.I don't believe the reason that/which he gave me. 作宾语Have you asked him the reason that may explain his success 作主语Ex. He was late .That's because he got up late..He got up late. That's why he was late.表语从句the reason why/for which he was late. 定语从句当先行词为way时;定语从句常用that; in which;或不用引导..way后的定语从句的引导词不用时较多..但如果关系词在句中作主语或宾语时;则用which或that 引导..如:This is the way that /in which I do such things.比较: Please do the experiment in the waythat/whichI have shown you.Ⅳ. 限制性定语从句与非限制性定语从句的区别：1. 形式上;非限制性定语从句往往用逗号隔开..2. 语法上;非限制性定语从句一般不用that.3. 语义上;限制性定语从句与先行词关系紧密;起限定作用;如果去掉了这个定语从句;整个句子就不完整或者会改变意思；而非限制性定语从句与先行词关系不是很紧密;对先行词起补充说明或描述的作用..This is the book I like best. 这就是我最喜欢的那本书..Beijing; which has been China's capital for more than 800 years ; is rich in cultural and historic relics. 北京是中国八百年之久的古都;它有着丰富的文化和历史遗产..4. 翻译时;限制性定语从句可译为一句较短的一般译为"的"字结构；而非限制性定语从句可译为两句..见上句翻译比较: He has a sister; who is a musician.He has a sister who is a musician.引导非限制性定语从句的关系代词;指人时用who; whom; whose ; 指物时用which ; whose; 关系副词when;where; why; etc.1. He studied hard at school when he was young; which leads to his success in his later life.2. Tom's father; who arrived just now; is a famous scientist.3. They set up a separate state of their own; where they would be free to keep Negroes as slaves.4. He was proud; which his brother never was.Ⅴ. 几个易混淆的关系代词的比较:●that & which:在定语从句中;which 和that 在指代事物时;一般可以互换使用;但并非在任何情况下都是这样;这里介绍宜用that; 而不宜用which 的情况.①先行词为不定代词;all;much;something;everything;anything;nothing;none;the one等;1.We should do all that is useful to the people .2.There's nothing that can be said about it .3.Do you mean the one that was bought yesterday②先行词被only; any; few; little; no; just; very; one of等词修饰时..1.The only thing that we could do was to wait.2.That's the very word that is wrongly used.The last place that we visited was the chemical works.You can take any =whichever seat that is free.I hope the little that I can will be of some help to them.比较 This is one of the best novels that were published last year.This is the only one of the best novels that was published last year.③先行词是序数词时或被序数词修饰时..1.When we talk about Wuxi; the first that comes into mind is Tai Lake.2.This is the third film that has been shown in our school this term.④先行词是最高级或被最高级修饰时..1.This is the best that can be done now.2.The most important thing that should be done right now is how to stop him from going on.⑤先行词既有人又有物;用which和who都不适合;这时宜用that. 如：1.The writer and his novel that you have just talked about is really well known .2.The rider and his bike that had run over an old woman were held up by the police.⑥被修饰词为数词时.1.Yesterday I caught two fish and put them in a basin of water .Now you can see the two that are still alive .⑦如果有两个从句;其中一个关系代词已用which ;另一个关系代词宜用that;以避免语言的单调或重复..Edison built up a factory which produced things that had never been seen before.⑧疑问词是who或which;关系代词宜用that;以避免重复..1. Which is the book that you like best2. Who is the man that is standing at the gate⑨主句是There be 结构;修饰其主句的定语从句宜用that 作关系代词. 如：1. There is still a seat in the corner that is still free.⑩被修饰成分为表语时;或者关系代词本身是定语从句的表语时;该关系代词宜用that .1. That's a good book that will help you a lot.2. My home village is no longer the place that it used to be .定语从句中宜用which而不宜用that 的情况:①当关系代词的前面有介词时.1.A zoo is a park in which many kinds of animals are kept for exhibition.2.Is this the room in which Mr. White lives②在非限制性定语从句中.1.Crusoe's dog; which was are now very old; became ill and died .2.More and more people are beginning to learn English; which is becoming very popular in our country. which指代主句③在一个句子中有两个定语从句;其中一个定语从句的关系代词用了that; 另一个宜用which .1.
