定语从句详解 首先，（任何）从句结构：“关联词+从句主语+从句谓语” 位置：从句之首，主句先行词之后。 成分：关系代词和关系副词均在定语从句中充当句子成分。 非限制性定语从句： （1）反作补充说明，与主语关系不甚密切，朗读时先行词用降调并稍做停顿，多半逗号与主句隔开。 （2）能修饰整个句子，限制性定语从句则不能。与限制性定语从句含义不同，限制-是确指，非限制性定语从句是泛指。 （3）先行词为{专有名词，具有特指对象的名词}一般要用到非限制性定语从句。 （4）关系代词不能用that ，先行词指{人：用who、whom；物：which } 关系代词与介词 “介词+关系代词”既能引导非限制性定语从句，又能引导非限制性定语从句。介词要根据先行词、从句的谓语动词、从句中的形容词来选择，也可根据句意选择。 I．介词放在关系代词的前面时，介词短语只能用which代物；和用whom代人；whose还可在从句中与它所修饰的词一起作介词宾语。 This is the hero of whom we are proud. I want to find the very pen with which I wrote that letter. The boss in whose company my father worked is a very kind person. II．当介词放在句子的末尾时，可用that/which代物，that/whom/who来作为介词的宾语，且这个做介词宾语的关系代词往往忽略 This is the hero that (who/whom/忽略) we are proud of. 特: (1)from where为”介词+关系副词”结构,where作from的宾语,但也可引导定语从句。例如: We stood at the top of the hill,from where we can see the town. (2) 有些动词+介词所组成的短语动词，关系非常紧密，介词不能前置。例如：listen to，look at，depend on，pay attention to，take care of 关系代词的省略 首先注意只有限定性定语从句才能省略，非限定性定语从句绝对不能省略。 在下列情况下，可以省略关系代词。 i. 当关系代词在从句中担任动词宾语的时候 The people (who) we met at the party were very friendly to us. ii. 关系代词在从句中作介词宾语，而介词在句尾时 Here is the man (that) you have been looking for. iii. 关系代词在从句中作系动词的表语时 Shang Hai is no longer the city (that) it used to be. iv. who、which、that在there be句型中作从句主语时；和先行词为way（表示“方法”、“手段”时，定语从句用that或in which引导），关系代词总是省略。 There is an old man (who ) wants to see you. The number of motorcycles（that/which）there are in Shangyu is simply surprising. I don’t like the way (that) you talk to somebody else. 定语从句注意事项 一、认清定语从句中的分隔现象。 有时命题者为了加大试题难度，往往把定语从句融入其它结构之中来考查考生的综合运用能力，其常用的命题手段就是将定语从句的某一部分用插入语的方式分隔开，使考生分不清楚句子结构，从而误选答案。 Miss Yang was the only girl in the office who had been invited to the party.(这里先行词girl和关系代词who之间被介词短语in the office隔开了，不能误把office作先行词。) He took away all the flowers, which, of course, made the others unhappy.(这里of course是插入语，增加了句子的难度，如果将其去掉，句子结构就简单多了。) 二、掌握定语从句中的主谓一致。 这是指当先行词在从句中作主语时，从句的谓语必须在人称和数上与之保持一致。 The girl has put all the pictures in a box, which look pretty.(先行词pictures是复数，在从句中作主语，故从句的谓语用复数形式。) He is the only one of the doctors in the hospital who has two cars.( 在"one of +名词"结构中，通常名词是先行词；但在one前加the only，则one是先行词，故句子谓语用has。) 特：① one of + 复数名词 +关系代词+复数型动词 ②the (only) one of + 复数名词+关系代词+单数型动词 The Great Wall is one of the world-famous buildings that draw lots of visitors. Titanic is the (only) one of the most wonderful movies that has been produced in Hollywood. 三、区分定语从句与其相似句型。 在实际运用中，要分清到底是定语从句，还是并列句、状语从句、强调句或其它句型，然后再来确定关联词。 Mr Wu has two sons, and both of them are fond of playing golf.（这里and连接的是并列句，不能用whom代替them。如去掉and，就必须用whom代替them构成定语从句。） It was last night that the terrible fire broke out. （这里是"It was+被强调部分+that... "构成的强调句型，故连接词不用when。） 四、 What引导名词性从句，不能用于定语从句中。 关系代词用法 A)as引导的定语从句。 在中学英语中，as引导的定语从句必须掌握以下两个要点： 1. 用在the same... as；such... as；as much;as many结构中，as作主语,宾语或表语。代替先行词是人或物的名词。 I have the same mobile phone as you (have). (as作宾语) He is such a kind man as often helps others.(as作主语) 同时，要区分such... as与such... that...的用法，在such... that... 结构中，that引导状语从句，且在从句中不作成分。 He is such a kind man that all of us like him. (从句主、宾语不缺，故用that，不用as。) 2. as引导非限制性定语从句,通常先行词为整个句子,在定语从句中做主语、宾语或表语，用来代表主句所表达的意思 它引导的定语从句可位于主句之前,句子之中，主句之后。Which只能在句后，而且as有“正如”，“就象”义；而which一般强调主句所产生的结果。 As is known to us all, Taiwan is part of China. =Taiwan is part of China, as / which is known to us all. 常用的2：as is said above，as already mentioned above，as is known to all，as it is，as is often the case，as is reported in thenews paper，see，expect。 B）关系代词who的用法 （1） who 的前行词必须是人，在从句中可以担任主语，往往也可以代替在从句中担任宾 语的whom,但是它前边不能有介词，如果带了介词就必须用宾格的whom: （介词+whom） This is the teacher who teaches us mathematics. She is the girl whom (who) I went there with. （可以替代） She is the girl with whom I went there. （不可替代） （2）who，that在很多情况下可以通用，但是有些情况只能用who: 1. 先行词是one, ones, anyone的时候宜用who. One who has nothing to fear for oneself dares to tell the truth. The ones who flatter me don’t please me. Don’t tell anyone about the news who oughtn’t to know it. 2. 先行词为those的时候，宜用who为关系代词 Those who were not fit for their work could not see the beautiful clothes made of the magic cloth. Those who want to go to the Great Wall sign up here. 3. 当先行词有比较长的后置定语的时候 I met a foreigner in the street yesterday who could asked me questions in Chinese. 4. 一个句子中带有两个定语从句，其中一个定语从句的关系代词为that,另一个则用who. The boy that you met last night is the group leader who studies very hard. 5. 在there be 开头的句子中 There is an old man who wants to see you. There are many young men who are against him. C）关系代词whose的用法 whose是代词的所有格，修饰名词，它既可以代人也可以代物。当代物的时候，它相当于of which。这种定语从句可以转化为“the+（whose在从句中所修饰的名词）+of+which（whom）”引导的非限定性定语从句，先行词指人时用whom，先行词指物时用which。 I saw a woman whose bag was stolen. I’ll call a person whose father knows you. Which is the car whose owner you know? (Which is the car the owner of whichyou know) Please show me the book whose cover is red. (Please show me the book the cover of which is red) D） 关系代词that的用法： 从句中作主语时不能that省略，作宾语时可省略。 ①首先特别注意，that只能用在限定性定语从句中，在非限定性定语从句中永远不能选用that, 另外介词后边也不可用that, 而是跟which。 ②在限定性定语从句中，which和that在代替物的时候，一般可以通用。 有些情况下，只宜用that,而不宜用which I. 先行词是级形容词或者它前面有级形容词修饰的时候 This is the best that has been used against pollution. English is the most difficult subject that you will learn during these years. II. 先行词是序数词，或者它前面有一个序数词修饰的时候 He is the last person (that) I want to see. It is the first American movie of this kind that I’ve ever seen. III. 先行词既有人又有物，宜用that Do you know the things and persons that they are talking about? The bike and its rider that had run over an old man were taken to the police station. IV. 先行词是all, much, little，few， something, anything, everything, nothing,none, the one等不定代词时 You should hand in all that you have. We haven’t got much that we can offer you. I mean the one that you talked about just now. V． 先行词被不定代词修饰,如all, any, every, few, little, no, some，no sooner等。例如: You can take any toy that you like. 你可以拿走你喜欢的任何玩具。 VI. 先行词前面Only, one of，the only， the same, the very，the last 等词修饰的时候。 The only thing that we can do is to give you some money. Li Ming is the only one that wants to be a teacher. Li Ming is one of the students that want to be teachers in our class. VII. 主句已有疑问词who或者which的时候 Which is the bike that you lost? Who is the woman that was praixed at the meeting? VIII. 有两个定语从句，其中一个关系代词已用which, 另外一个宜用that. Edison built up a factory which produced things that had never been seen before. E）关系代词which的用法 which作主语、宾语、表语。作表语时指人、物，指人时一般指从事某种职业或有某种特征、品性、才能的人。 用法：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，代替主句所表达的整体概念或部分概念。在这种从句中，which可作主语、宾语、表语，多数情况下意思是与and this相似，并可指人。例如： He succeeded in the compitition，which made his parents very happy. 禁忌： ①如果作先行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。 ②如果作先行词的是anyone，anybody，everyone，someone，somebody，关系代词应该用who或whom，不用which。例如： Is there anyone here who will go with you？ ③定语从句中不能作定语，但有时“whose+n.”=“the+n.+of+which” ④在非限定性定语从句中，只宜用which, 不宜用that. Beijing, which is the capital of China, is a very beautiful city. ⑤在限定性定语从句中which和that在指代物的时候常常可以通用，但是有时只宜用which而不用that： I 关系代词前面有介词的时候 This is the hotel in which you will stay. II 如果有两个定语从句，其中的一句的关系词是that, 另一句宜用which. Let me show you the novel that I borrowed from the library which was newly open to us。 如何正确地区分定语从句与同位语从句 一、 定语从句是形容词从句，其作用相当于一个形容词，是用来修饰前面的名词或代词的；同位语从句是名词从句，其作用相当于一个名词，是对前面的名词作进一步解释的。例如： 1． We heard the news that he had told her. 我们听到他对她说的消息。 2． We heard the news that he had won the game. 我们听到消息他赢得了比赛。 例1中的that从句的作用相当于一个形容词，其作用是修饰the news；例2中的that从句的作用相当于一个名词，是对the news的进一步说明。 二、定语从句的引导词在从句中充当一定的成分，可作主语、宾语、状语等；而同位语从句中的引导词在从句只起连接作用，不作任何句子成分。例如： 1. A plane is a machine that can fly. 飞机是一种能飞的机器。 2. The fact that they didn't finish the work has to be faced. 必须面对事实，他们没有完成工作。 例1中的引导词that在从句中充当句子成分，作从句的主语，故为定语从句；例2中的that只起连接作用，引导从句解释fact的内容，不作任何句子成分，故为同位语从句。 三、引导定语从句的关联词在从句中作宾语或状语时，可以省略或被其他词代替；而同位语从句的引导词一般不能省略，更不能被代替。例如： 1. The news that she heard is true. 她听到的消息是真的。 2. The news that she will go abroad is true. 她将出国这消息是真的。 例1是定语从句，that可省略；例2是同位语从句，that不能省略。 3. The reason why he was chosen remains unknown. 他为什么被选上的原因还是不清楚。 4. The idea why he was chosen attracted our attention. 他为什么会被选上，这一想法引起我们的注意。 例3中why引导的是定语从句，why可以被 for which或 that 代替；例4中 why引导的是同位语从句，why 不能省去，也不能被其它词代替。 四、同位语从句与其所修饰的名词之间是一种同位关系，二者之间存在逻辑上的系表关系，可用“主+系+表”结构来表示。例如： The news that he won the first place is true. 他赢得冠军的那个消息是真的。 上句若用“主+系+表”结构来表示，则是： The news is that he won the first place. 消息是他赢得了冠军。 意思合理，系表结构成立，故为同位语从句。 五、定语从句所修饰、限定的先行词可以是各类名词，可以有复数形式；而同位语从句一般都与抽象名词同位，一般没有复数形式。例如： 1. The possibilities that she was offered seemed very great.她得到的可能性似乎大些。 2. Her mother was worried about the possibility that her daughter dislike to go to school. 她的母亲很担心，她女儿有可能不喜欢上学。 例1中的possibilities是定语从句的先行词，可用复数形式；例2中的possibility是抽象名词，后接的是同位语从句，一般不用复数形式。 六、由when, why, where引导的定语从句分别修饰或说明表示时间、原因或地点的词，但它们引导的同位语从句一般不和表示时间或地点的词同位。例如： 1. I still remember the day when I first came to Beijing. 我仍然记得初次来北京的那天。 2. I have no idea when she will be back. 我不知道她何时回来。 3. This is the house where I lived two years ago. 这是我两年前住的房子。 4. The question where we shall have a meeting hasn't decided. 我们到什么地方去开会，这个问题没有决定。 例1、3中的when和 where引导的是定语从句，day 和house分别表示时间和地点；例2、4中的when和 where引导的是同位语从句. 关系副词和定语从句 I．关系副词也可以引导定语从句 关系副词在从句中分别表示时间．地点或原因。 When:表示“……时候的”，是关系副词引导限制、非限制性定语从句，修饰指时间的名词，且在从句中作时间状语。 This is the hour when the place is full of people. Where：作地点状语，先行词是指地点的名词，引导限制、非限制性定语从句。 注：先行词是指地点的名词时，谓语动词是及物的就用that（which），负责就用where. Why或for which:作原因状语,先行词必须是the reason。但是the reason在从句中作主语或宾语时要用that，which。 II. that可引导定语从句表示时间．地点或原因 That有时可以代替关系副词 when, where 或者why引导定语从句表示时间．地点或原因，在 that引导的这种定语从句中，that也可以省去。
定语从句是由关系代词和关系副词引导的从句,其作用是作定语修饰主句的某个成分,定语从句分为限定性和非限定性从句两种.状语从句分为时间状语从句,结果状语从句,让步状语从句,原因状语从句,条件状语从句以及行为方式状语从句.名词从句包括主语从句,宾语从句,表语从句和同位语从句及there be句型. 一、 限定性定语从句 1. that即可代表事物也可代表人,which代表事物；它们在从句中作主语或宾语,that在从句中作宾语时常可省略关系词,which在从句中作宾语则不能省略.而且,如果which在从句中作“不及物动词＋介词”的介词的宾语,注意介词不要丢掉,而且介词总是放在关系代词which的前边,但有的则放在它原来的位置 2. which作宾语时,根据先行词与定语从句之间的语义关系,先行词与which之间的介词不能丢 3. 代表物时多用which,但在带有下列词的句子中用that而不用which,这些词包括all, anything, much等,这时的that常被省略 4. who和whom引导的从句用来修饰人,分别作从句中的主语和宾语,whom作宾语时,要注意它可以作动词的宾语也可以作介词的宾语 5. where是关系副词,用来表示地点的定语从句 6. when引导定语从句表示时间 〔注〕值得一提的是,表示时间“time"一词的定语从句只用when引导,有时不用任何关系代词,当然也不用that引导 By the time you arrive in London, we will have stayed there for two weeks. I still remember the first time I met her. Each time he goes to besiness trip, he brings a lot of living necessities, such as towers, soap, toothbrush etc. 7. whose是关系代词,修饰名词作定语,相当于所修饰成分的前置所有格 8. 当从句的逻辑主语是some, any, no, somebody, anybody, nobody, something, anything, everything或nothing时,常用there is来引导 二、非限定性定语从句：非限定性定语从句的作用是对所修饰的成分作进一步说明,通常和主句间用逗号隔开,将从句拿掉后其他部分仍可成立 1. which引导的非限定性定语从句来说明前面整个句子的情况或主句的某一部分 2. 在引导限定性定语从句时,that有时相当于in which, at which, for which或at which Attitudes towards daydreaming are changing in much the same way that(in which) attitudes towards night dreaming have changed. 人们对白日做梦的态度正在改变,这与人们对夜间做梦的看法的变化有非常相似之处. I like the music for the very reason that(for which) he dislike it. 我出于某种原因喜欢这种音乐,而他恰恰与我相反. We arrived the day that(on which) they left. 刚好我们到的那天他们走了. 3. 有时as也可用作关系代词 4. 在非限定性定语从句中,不能用that,而用who, whom代表人,用which代表事物 三、定语从句结构错误 1. 缺关系词 2. 从句中缺成分 摘自《简明英语语法》 在英文中,有两种定语从句：限定性定语从句与非限定性定语从句.这两种定语从句在其功能和形式方面都有明显的区别： 限定性定语从句限定性定语从句与主句的关系很紧奏,对其先行词起限定、修饰的作用.如果将其去掉,会影响句子意思的完整性；有时甚至于引起费解、误解.例如： Rainforests are being cleared for valuable timber and other resources to speed up the economic growth of the nationsin which they are located . 为了加速他们各自所在国家的经济发展,热带雨林作为有价值的原木和其他资源正为人们所砍伐. Ocean currents affect the climates of the lands near which they flow. 洋流影响其流经的附近地区的气候. They explained the reason to us why they had hated us before. 他们向我们解释为什么他们不喜欢我们的原因. 非限定性定语从句非限定性定语从句在形式上就与主句很松散,它与主句之间有一个逗点","隔开；它对其先行词没有限定、修饰的作用,只起补充、说明的作用.有时也用它来对全句进行补充、说明.即使将其去掉,也不会影响句子意思.由于上述原因,非限定性定语从句在表达意思方面也有别于限定性定语从句.另外,非限定性定语从句在中文译文里,我们往往将其作为一个分句处理,而不把它作定语翻译. 例如：Earlier , the Babylonians had attempted to map the world , but they presented it in the form of a flattened disc rather than a sphere , which was the form adopted by Ptolemy . （此句中,非限定性定语从句是对先行词a sphere进行补充、说明.） 更早之前,巴比伦人曾试图绘制世界地图,但是他们把它绘制成平盘状而不是托勒密所采用的球体状. The bination of satellites, which tran *** it information , puters , which store information , and television , which displays information , will change every home into an education and entertainment center . （此句中,三个非限定性定语从句分别对三个先行词：satellites ,puters和television进行补充、说明.如果去掉这三个非限定性定语从句,那么句子可简化为： The bination of satellites , puters and television will change every home into an education and entertainment center .）卫星能传输信息,计算机能储存信息,电视能显示信息,把这些手段结合起来可以使每个家庭都成为教育娱乐的中心. The sun heats the earth , which makes it possible for plants to grow .（此句中,非限定性定语从句是对全句进行补充、说明,将全句表达的意思看成"一件事情）.太阳给予大地热,这就使植物的生长成为可能. The old man has a son , who is in the army .（此句中,非限定性定语从句是对先行词son进行补充、说明.但本句所传达的信息是："这位老人只有一个儿子" .如果将此句改写成限定性定语从句： The old man has a son who is in the army . 那位老人有一个在部队工作的儿子.那么,限定性定语从句就要对先行词son进行限定、修饰.这样一来,句子所传达的信息就变成了："这位老人有一个儿子在部队工作,还有其他的儿子在干别的工作".）那位老人有一个儿子,他在部队工作.

本句话是一个典型的非限制性定语从句，主从句关系松散。
【篇六】
问：介词+which/whom引导的定语从句是怎么一回事？
答：如果关系代词which/whom本身在定语从句中充当一个介词或介词短语的宾语时，有时可以将介词直接放在which/whom的前面，这样就出现了“介词+关系代词”及“名词或代词+which/whom”或“复合介词+which/whom”等的结构。
例如：
（1）I know the man to whom you talked juest now.
我认识你刚才与之说话的那个人。
（2）Life is a flower of which love is honey.
人生是朵花，爱情是花蜜。
（3）Soon they spotted a mountain,on top of which stood a temple.
不久他们发现了一座山，山顶上有座庙。

定语从句【知识简介】名词或代词由一个从句来修饰，该从句即定语从句。定语从句一般后置，但as引导的修饰全句的定语从句可以前置。引导定语从句的词有关系代词that, which, who, whom, whose, as等以及关系副词when, where, why等。关系代词或关系副词放在被修饰的名词或代词（又叫做先行词）和定语从句之间起联系作用，同时又作定语从句中的一个成份。【要点难点】1)that和which的用法区别只用that的情况：①先行词由最高级修饰时，如the best work that I can do。②先行词由序数词修饰时，如the second book that I bought。③先行词由the last, the only, the same, the very等修饰时。④先行词是不定代词all, anything, everything, little, much, nobody, nothing等时，如anything that he does; all that I can do now等。⑤先行词有any, no, all等限定词时，如all the words that I’ve learned。⑥先行词为词组，该词组既含人又含物时，如the city and the people that I visited。只用which的情况：①在非限定性定语从句中（定语从句前有逗号）。②介词后。请看that和which的使用例句：It’s the best film that’s ever been made on the subject of madness. 这是以精神病为题材而拍摄的影片中最好的一段。Shakespeare is the greatest poet that England has ever had. 莎士比亚是英国最伟大的诗人。（本句中先行词虽是人，但由于前面也有形容词最高级修饰，仍用that较好）Take the first opportunity that offers. 抓住第一个出现的机会。He is the last person that one would suspect. 人们最不可能怀疑他。Man is the only creature that is gifted with speech. 只有人类具有语言的天赋。A fool sees not the same tree that a wise man sees. 一个傻瓜看到的树和一个聪明人看到的树不一样。Those were the very words that he said at the meeting. 这些就是他在会上说的原话。All that glitters is not gold. 闪光的并不都是金子。Anything that you have to say had better be said in each other’s presence. 有话最好当面说。There’s still much that is to be done. 仍然有很多事要做。I have changed my mind. Nothing that you say will change it. 我已经改变了主意，无论你说什么也无法改变它。Nobody that was there could convince her of her mistake. 这那儿没有一个人能使她明白她的错误。Every paper that you read gives the same story. 你看的每份报纸都报道同样的新闻。I still can’t forget the places and the people that I visited during last summer vacation. 我仍然难以忘怀去年暑假我见到的地方和人。2)关系代词（that, which, who, whom等）和关系副词（when, where等）的用法区别①关系代词在定语从句作主语、宾语或表语，而关系副词在定语从句中作状语。②分析时主要从动词的及物性或有无介词来考虑。看如下对比例句：①This is the factory where my father once worked. 这是我父亲曾工作过的工厂。（worked是不及物动词，不接宾语，所以不用which/that。where相当于in the factory）This is the factory which/that my father once worked in.（worked in的宾语是factory，故用关系代词which/that）②I will never forget the days which/that I spent in the wood near our village. 我忘不了我在我村边小树林里度过的日子。（the days是spent的宾语）I will never forget the days when I spent my holidays with my grandparents. 我忘不了我和我的祖父母一起度假的日子。（spent的宾语是holidays，不是the days）I will never forget the small village where I spent my holidays. 我忘不了我度假的小村庄。（与上句一样，spent的宾语是my holidays）③Is this the school which/that you visited the other day? 这是你几天前参观过的学校吗？（the school作visited的宾语）Is this the school where you visited your teacher the other day? 这是你几天前拜访你老师的学校吗？（visited在定语从句中有自己的宾语your teacher，所以不用that/which）3)those who和he who句型两个常用句型。He who常用于谚语中。请看例句：He who doesn’t reach the Great Wall is not a true man. 不到长城非好汉。God helps those who help themselves. 上帝帮助自强的人。He who insists on seeing with perfect clearness before he decides never decides. 坚持一切看清楚之后才做决定的人永远也做不了决定。He was a bold man who first ate an oyster. 第一个吃牡蛎的人是勇敢的人。4)whose的用法whose是关系限定词，既可以指人也可以指物，即既可以说“某人的”，也可以说“某物的”。Fortune never helps the man whose courage fails. 运气永远不会帮助丧失勇气的人。That's the man whose house has burned down. 那就是那位房屋烧毁的人。Have you noticed the house whose windows are closed now? 你注意到了那家窗户关着的房子吗？He’s written a book whose name I have completely forgotten. 他写了一本书，书名我完全忘记了。Above the trees are the mountains, whose magnificence the river faithfully reflects on the surface. 在树林的高处是山，其壮丽的景色完全映照在河面上。注：在正式文体中，指物时，whose往往用of which表示。of which可放在被修饰的名词之前或之后，而whose只能放在被修饰的名词之前。例如：The house whose windows/of which the windows/the windows of which are broken is unoccupied.（那间窗户破了的房屋没人居住。）whose前有时有介词。The teacher in whose class my daughter is studying is a kindhearted man. 我女儿所在的那位老师心地善良。Michel Croz, with whose help, Woolworth climbed to the mountain top, was one of the prefessional guides. 米歇尔?克罗兹是职业向导之一，在他的帮助下伍德沃斯攀登到了山顶。Then we had a chance to talk with that tall man, from whose accent we at once knew that he came from Hunan Province. 后来我们有机会和那个高个子说话，我们从他的口音迅速知道他是个湖南人。5)限制性定语从句和非限制性定语从句的区别限制性定语从句和非限制性定语从句的区别：限制性定语从句是先行词（即被修饰词）不可缺少的定语，限制性定语从句前不用逗号隔开；非限制性定语从句只是对先行词的附加说明，如果去掉，先行词所述对象仍很清楚，非限制性定语从句前常用逗号隔开。这里有两个例句及分析：Those who want to go camping please tell the monitor. 想去野营的人请告诉班长。（定语从句who want to go camping在句中不可少，否则先行词those不知道指谁，也就变得无意义，因此它是限制性定语从句。）Football, which is a very interesting game, is played all over the world. 足球风靡全世界，它是一项很有趣的运动。（定语从句which is a very interesting game只是对意义已很明确的football作一个补充说明，因此它是非限制性定语从句。）注意，非限制性定语从句可以用关系代词which, who, whom, whose, as及介词+which/whom等引导，也可以用关系副词when, where引导，但不能用that引导。另外，非限制性定语从句中的关系代词或关系副词是不能省略的。6)whom的用法只有作定语从句中的宾语时才能用whom；介词后用whom不用who。口语中whom前无介词时可用that或who代替。My brother, whom you met the other day, has gone abroad. 前几天你遇见过的我的那个兄弟，出国去了。I have a few friends whom I could ring to see if they are free. 我有几个朋友，我可以打电话去联系，看看他们是不是有时间。You have many people around you who are kind to you but whom you will soon forget. 你周围有许多对你好的人，但你都会很快忘记他们。There came a lot of children, most of whom I didn’t know. 来了许多孩子，大多数我都不认识。7)介词＋which/whom引导的定语从句如果关系代词which/whom本身在定语从句中充当一个介词或介词短语的宾语的时候，有时可以将介词直接放在which/whom的前面，这样就产生了“介词＋关系代词”及“名词或代词＋介词＋which/whom”或“复合介词＋which/whom”等的结构。I know the man to whom you talked just now. 我认识你刚才与之说话的那个人。Life is a flower of which love is honey. 人生是花朵，爱情是花蜜。He was educated at the local grammar school, after which he went on to Cambridge. 当在当地的一所中学上学，此后就去上了剑桥大学。It’s a family of five children, all of whom are studying music. 这一家有五个孩子，他们都在学音乐。In the attic we found some apples, none of which was fit to eat. 在阁楼里我们发现了一些苹果，其中没有一个能吃的。I have three brothers, all of whom have gone abroad. 我有三个兄弟，他们都出国了。Soon they spotted a mountain, on top of which stood a temple. 不久他们发现了一座山，山顶上有一座庙宇。8)why引导的定语从句关系副词why用在reason之后，只引导限制性定语从句，why在从句中作状语，表示原因。Give me the reason why you should be interested in his affairs. 告诉我你为什么竟对他的事这样感兴趣。The reason why she was ill was that she had eaten bad meat. 她生病的原因是她吃了变质的肉。That is the reason why he raised the question. 这就是他所以提出问题的原因。注意：有时reason后不一定是why引导的定语从句。如下列句子中，reason后接的是which/that引导的定语从句，这是因为，reason在定语从句中作主语或宾语。Is this the reason which/that the chairman gave at the meeting? 这就是主席在会上所给的理由吗？I really can’t understand the reason that/which he explained. 我实在无法理解他所解释的理由。9)where引导定语从句有时修饰一些具有抽象意义的表示地点的名词，如situation, point, position等等。If you are ever in a situation where someone starts shooting, drop to the ground. 如果你遇到有人要射击的情况就摔倒在地上。But after a few days’ stay they got to the point where they could read each other's thoughts. 不过呆了几天之后，他们到了一个彼此能理解相互想法的阶段。It got to the point where I couldn't remember any of the reasons I loved him. 到那时候，我无法记起我爱他的任何理由了。10)the way后的定语从句The way后的定语从句用in which引导，in which可以用that代替，而that又可以省略。所以，表达“某人做某事的方法”有三种形式：1. the way in which somebody does something 2. the way that somebody does something 3. the way somebody does )which指代前面的句中的内容which的这一用法只能以非限定性定语从句出现。Jenny was late for school a third time during the week, which made her teacher very angry. 詹妮一周内第三次迟到了，这使得她老师很生气。?He left early, which was wise. 他早早地离开，那是很明智的。He suddenly became wealthy, which changed his whole mode of life. 他忽然变得富有了，这改变了他整个的生活方式。He often helps me with my lessons, which is kind of him. 他经常在功课方面帮助我，真是感谢他。12)which作关系限定词的情况which作为关系限定词时，其本身代替前面所陈述的内容。She asked me to see the doctor, which advice I took at once. 她要我去看医生，我立即采纳了她的建议。He is studying economics, which knowledge is very important today. 他正在攻读经济学，这门知识在今天是非常重要的。He believes in students’ doing more homework, which idea I am quite opposed to. 他相信要让学生做更多的家庭作业，我非常反对这个观点。which的这种用法常伴随介词而用。常见的词组形式有by which means, during which time, in which case, for which mistake, for which reason等等。She may have missed the train, in which case (=if this happens) she won't arrive for another hour. 她也许没赶上火车，如果那样的话，她一小时是到不了的。I called him by the wrong name, for which mistake I apologize. 我叫错了他的名字，为此我道歉。He didn’t feel well that morning, for which reason he didn’t attend school. 那天早晨他感到不舒服，因此，他没去上学。Tom spent four years in college, during which time he learned French. 汤姆在大学上了四年学，在这段时间里，他学会了法语。13)as用法关系代词as引导定语从句有两种形式。（1）as引导一个非限制性定语从句修饰一个分句，as代表该分句所表达的整个概念或其中一部分的概念。as定语从句可置于句首、句中或句尾；as本身在从句中充当主语、宾语及表语。（2）用于as … as, the same … as, so … as, such … as等结构中。as用法的第一种情况：As is known to all, the earth moves around the sun. 众所周知，地球围绕太阳旋转。He must be an African, as may be seen from the colour of his skin. 他准是个非洲人，这可以从他的肤色看得出来。If he comes late, as is usual, for another time, we’ll not receive him. 如果他再一次像以往那样迟到，我们就不接待他了。She is a fine singer, as her mother used to be. 她是个很出色的歌唱家，像她的母亲当年一样。As you will find out, all is now settled. 你会发现，现在一切都解决了。Helen is somewhat crazy, as everyone could see. 海伦有些神经错乱，这种情况每个人都看得出。注意这一类的as表面上看好像和which代替全句时的用法相似，但as引导的定语从句的最大特点是它的意思多侧重于表达“（正）像……、（正）如……”及类似的意思。一般说来，当关系代词在从句中作be动词的主语或一般动词的宾语时，which和as可交替使用；当关系代词在从句中作一般动词（非be动词）的主语时，只能用which；as可置于句首、句中，而which则不能。例如：He was late for school, as/which was usual with him. 他上学迟到了，他经常这样。He saw the girl, as/which he had hoped (he would). 他见到了那位姑娘姑娘，正像他希望的那样。He saw the girl, which delighted him. 他见到了那位姑娘，这使得他很开心。（句中的which不能用as代替，因为从句中的delighted是非be动词）As has been said before, grammar is not a set of dead rules. 正如上面所说的那样，语法不是一套死的规则。（句中的As不能用Which代替，因为此定语从句置于句首）as用法的第二种情况：There’s as good fish in the sea as ever came out of it. 海里有的是鱼；天涯处处有芳草。Here is so big a stone as no man can lift. 这是一块没人能搬动的大石头。Her manner and attitude toward him were quite the same as they had always been. 她对他的举止和态度和往常是完全相同的。He does not possess such a mind as is necessary to a scientist. 他缺乏科学家所必须具备的头脑。Such food as they gave us was scarcely fit to eat. 他们给我们的食物很不适合吃。A man such as he will surely succeed. 像他这样的人是肯定会成功的。I haven’t much money but you can use such as I have. 我钱不多，可你能用我所有的钱。Such as you see is all we have. 你所见到的就是我们所有的东西。14)介词+whom/which + to do的类定语从句结构的不定式用法This is a useful tool with which to cut steel. 这是可以用来切割钢材的工具。Can you recommend someone from whom to learn how to use the software? 你能推荐一个可以向他讨教使用这一软件的人吗？It’s not a room in which to live comfortably. 这不是可以舒适居住的房间。这一结构的介词位置固定，不可移到动词之后，如第一句中的with which to cut steel不可改成which to cut stell with。15)嵌入式定语从句有一种定语从句，在其从句中的主语和谓语之间有一个插入语如I think。这一种定语从句叫做嵌入式定语从句。嵌入的分句的谓语动词常常是think, believe, guess, imagine, say, suppose, be sure, doubt等等。She offered a suggestion which she said would interest you. 她提出一个她说一定会引起你兴趣的建议。He wrote letters to every person and organization that he believed might be able to help. 他写信给每个人和每个组织，他相信可能有帮助。That is the engineer who I think is the right man chosen for the job. 那位就是我认为适合被选派做这项工作的工程师。
定语从句，一个句子跟在一名词或代词（先行词）后进行修饰限定，就叫做定语从句。通俗来讲，从句在整个句子中做定语，这个从句就叫做定语从句。
定语从句定语从句是由关系代词和关系副词引导的从句，其作用是作定语修饰主句的某个名词性成分，定语从句分为限定性和非限定性从句两种。一、限定性定语从句即可代表事物也可代表人，which代表事物；它们在从句中作主语或宾语，that在从句中作宾语时常可省略关系词，which在从句中作宾语则不能省略。而且，如果which在从句中作“不及物动词＋介词”的介词的宾语，注意介词不要丢掉，而且介词总是放在关系代词which的前边，但有的则放在它原来的位置作宾语时，根据先行词与定语从句之间的语义关系，先行词与which之间的介词不能丢3.代表物时多用which，但在带有下列词的句子中用that而不用which，这些词包括all,anything,much等，这时的that常被省略和whom引导的从句用来修饰人，分别作从句中的主语和宾语，whom作宾语时，要注意它可以作动词的宾语也可以作介词的宾语是关系副词，用来表示地点的定语从句引导定语从句表示时间［注］值得一提的是，表示时间“time"一词的定语从句只用when引导，有时不用任何关系代词，当然也不用that引导BythetimeyouarriveinLondon,是关系代词，修饰名词作定语，相当于所修饰成分的前置所有格8.当从句的逻辑主语是some,any,no,somebody,anybody,nobody,something,anything,everything或nothing时，常用thereis来引导
英语定语从句解析
1.先行词为all, anything, something, nothing, everything, much, little, none等不定代词时，关系代词一般只用that，不用which。在大多数情况下that可以省略.
Please tell me everything you know about the matter.
Thats all we can do at the moment.
2.as引出的限制性定语从句
在such as的结构中as可作关系代词，引出限制性定语从句。有时和same连用，在从句中可作主语、宾语或表语等。
Such people as were recommended by him were reliable.
Ive never seen such a talented young man as he is.
I have the same trouble as you .
3.as引出的非限制性定语从句
as可作关系代词引出非限制性定语从句，代替整个主句，通常译为(正)如一样，(正)象一样等。as引导的从句一般用逗号与主句隔开，可以位于主句的前面、中间或后面.
I live a long way from work, as you know.
She did not, as her friend had feared, break down.
As is generally accepted, economic growth is determined by the smooth development of production.
4.分隔式定语从句
定语从句一般紧跟在先行词之后，但有时会被其他句子成分与先行词隔开，从而构成分隔式定语从句。
1)介词后面的关系词不能省略。
2)that前不能有介词。
3)某些在从句中充当时间，地点或原因状语的介词+关系词结构可以同关系副词when 和where 互换。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.
Do you remember the day on which you joined our club? 还记得你加入我们俱乐部的那一天吗?
Do you remember the day when you joined our club?
18.6 as, which 非限定性定语从句
由as, which 引导的非限定性定语从句，as和which可代整个主句，相当于and this或and that。As一般放在句首，which在句中。例如：
As we know, smoking is harmful to ones health. 如我们所知，吸烟有害健康。
The sun heats the earth, which is very important to us. 太阳使地球暖起来，这对我们人类很重要。
典型例题
1)Alice received an invitation from her boss, ___came as a surprise.
A. it B. that C. which D. he
答案C. 此为非限定性从句，不能用 that修饰，而用which.，it 和he 都使后句成为句子，两个独立的句子不能单以逗号连接。况且选he句意不通。
1、限定性定语从句和非限定性定语从句
定语从句就其与先行词的关系而言，可分为限定性定语从句和非限定性定语从句。限定性定语从句和先行词之间没有逗号，表示对先行词起修饰限制作用;而非限定性定语从句和先行词之间有逗号分开，是对先行词进行补充说明，相当于并列句。
如：He is the man who has a strong personality. 他是个个性很强的人。(限定性定语从句)
My brother, who works abroad, is coming next week. 我哥哥在国外工作，他下周将回来。(非限定性定语从句)
注：
1) 非限定性定语从句不能用that来引导，一般用which，as或who(指人)。用which或as引导时，既可以修饰主句的部分内容，也可修饰主句的全部内容。如：
He spoke confidently, which impressed me most. (which指代整个主句，在从句中作主语)
2) as引导的非限定性定语从句既可以放在主句之前，也可以放在主句之后，但which或who引导的非限定性定语从句不能放在主句之前。如：As we all know, the moon is a satellite of the earth.The large area is covered with thick snow, which affects people‘s life greatly.
3) 在限定性定语从句中，关系代词作宾语时可以省略;但在 非限定性定语从句中，关系代词作宾语时不能省略。如：
The film (which) I saw last night is about a young teacher. (which可以省去)
She introduced me to her husband, whom I hadn’t met before. (whom不能省去)
2、只用关系代词that，不用 which，who或whom的几种情况
1)当先行词是all, everything, nothing, something, anything, little, much, none, few等时。如：All that you want are here.
2) 当先行词被all, no, some, any, every, a few, a little, much, only, very等修饰时。如：There is no person that doesn’t make mistakes.
3)当先行词被序数词或形容词最高级修饰时。如：This is the best film that I have ever seen.
4)当出现两个或两个以上的先行词，并同时兼指人和物时。如： We are talking about the people and countries that we have
visited.
5) 当主句是以which 或 who 开头的特殊疑问句时。如： Who is the person that is standing over there?
6) 当定语从句为there be 句型时，关系代词只用that，
但经常可以省略。如： I know the difference (that) there is between you.
7)当关系代词在从句中作表语时，常用that。如：He does not seem to be the man that he was
他似乎和过去不一样了。
3、 as 与其他词连用引导的定语从句
as 引导定语从句时，可指人也可指物，通常与the same，such，so等连用，形式为：the same… as，such… as，as …as，so… as。As在定语从句中可作主语、宾语、表语等。如：
She knew he felt just the same as she did. 她知道他的感觉与她自己的一样。(as代替事，作宾语)
I lend you such books as will interest you. 我借给你使你感兴趣的书。(as代替物，作主语)
注：the same… as 和the same… that的用法不同。as引导的定语从句表示其内容与主句所讲的事物“相似”，指同类事物;that引导的定语从句表示其内容与主句所讲的事物是“同一个”，指同一事物。如：
This is the same pen as I lost yesterday. 这和我昨天丢的笔一样。(类似的笔)
This is the same pen that I lost yesterday. 这支笔就是我昨天丢的'那支。(同一支笔)
4、“介词+关系代词”引导的定语从句
在“介词+which/whom”结构中，介词的选择取决于3种情况：
1)定语从句中谓语动词或表语的搭配。如： This is the college in which I am studying. He is the man about whom we are talking.
2)先行词与介词的习惯搭配。如： The speed at which the machine operates is shown on the meter.
仪表上显示出这台机器运转的速度。
3)当定语从句为最高级时只能用of which; 否则用其他介词。如： I have five dictionaries of which Longman Dictionary is the best. I have five dictionaries among which Longman Dictionary is published in UK.
注：不可拆分的动词短语介词不能提前，如put up with;有的短语可能有不同的介词搭配，此时需要根据上下文来确定。如：be familiar with/to，compare with/to等。
有时为表意清楚，还可以在关系副词where/ when前加介词from, to等。如：
China is the birthplace of kites, from
where kite flying spreads to Japan, Korea, Thailand and India.
中国是风筝的故乡，从这里，放风筝的运动传到了日本、韩国、泰国和印度。
注定语从句和同位语从句的区别
定语从句在复合句中的功能相当于形容词，它对先行词起修饰、描述或限制作用。而同位语从句则属于名词性从句，对与它有同位关系得名词作进一步解释，使其内容具体化。例如：
She felt very sad because of the news that her husband was killed in an aircraft crash. (同位语从句)
The fact that she told me made me very angry. (定语从句)
关系代词as与which引导的非限制性定语从句，其先行词都可以是整个主句，指代主句的整个意 思。但as和which具有不同的词义、句法和用法。
1. as引导的从句表示说话人的看法、态度、解释或评论
引导定语从句时，as仍具有正如，像，由……可知等意思，翻译时 有时可不必译出。as定语从句常含有这些动词：see， know， hear， watch， remember， say， tell， show， expect， guess等，这类动词与as连用几乎成了一种固定搭配。as引导的此类从句可以置于句首、句中或 句尾。如：
The famous magician Liu Qian， as we all know， is from Taiwan. 众所周知，著名魔术师刘 谦是台湾人。
There is a net bar around here， as I remember. 我记得这儿附近有一家网吧。
As is often the case， girls like dolls while boys like guns. 女孩子喜欢玩具而男孩子 喜欢枪，这是常见的情况。
2. which引导的从句对主句所叙述的事情进行补充说明，表明事物的状态或结果
which此时指前面主句所提到的这件事，常译为这一点，这件事等。这时它所引 导的从句与主句之间常含有并列、因果关系。注意，它引导的从句不像as那样位置灵活，它只能位于主句 的后面。如：
He changed his mind again， which made us all angry. 他又改变了主意，这使我们大家都生 气了。
She tore up my photos， which (=and that) upset me.她撕碎了我的照片，这使我很不安。
3. 在从句中作定语或介词的宾语时，要用which，不用as
Jenny might come， in which case I‘ll ask her. 詹妮可能会来，要是那样的话我就去问 她。
She graduated from a local middle school， after which she went to Beijing University. 她毕业于当地的一所中学，之后她去了北京大学。
4. 当从句的谓语动词是否定形式或含着一个复合宾语时，一般用which而不用as
He pretended not to know me， which I didn’t understand. 他假装不认识我，这是我搞 不明白的。
He admires everyone in his class， which I find quite strange. 他羡慕班里的每个学生， 我认为太奇怪了。
【特别说明】
as引导非限制性定语从句的最大特点是位置灵活；其次，as有以下常见的，而which不具备的 固定表达：
as we all know 众所周知
as I can remember 正如我所记得的
as often happens 正如经常发生的那样
as we expect 正如我们预料的那样
as you see 这一点你明白
as was expected 正如预料的那样
as can be seen 看得出来
as may be imagined 正如可以想象的那样
as has been said above 如上所述
as we all can see 正如我们都能看到的那样
as is often the case 像常规那样
as everybody can do 正如人人都能做到的那样
1. 分隔定语从句。
先行词与定语从句之间有时也会插入别的成分，构成先行词与定语从句的隔离，这种从句叫分隔定语从句。例如：
This is the article written by him that I spoke to you about.
He was the only person in this country that was invited.
①因定语从句过长，为使句子保持平衡，常将定语从句和其所修饰的名词或代词分开。
The film brought the hours back to me when I was taken good care of in that faraway village.
②在定语从句中使用“插入语”以增加语言的灵活性。
The pen I thought I had lost is on my desk，right under my nose.
2. as 和 which 引导的定语从句。
① as 有“正如，就像”之意，在非限制性定语从句中充当主语、宾语或表语，从句可位于主句的前面、中间或后面，一般用逗号与主句隔开。
As we had expected，her performance was wonderful.
A panda， as we know，is a lovely animal.
Tom is the tallest in our class，as you know.
但 which 引导的非限制性定语从句一般只能放在主句之后。例如：
The result of the experiment was very good，which we hadn’t expected.
②在主谓宾结构的非限制性定语从句中，which 和 as 作宾语时可互换使用。
He was an Englishman，which / as I knew from his accent.
作主语时通常用 which ，而不用 as .但在“主语 +be+done ”结构中，as 作主语。例如：
He passed the examination，as was known.
③ as 引导非限制性定语从句时，通常用在表示肯定意义的从句中，而不能用在表示否定意义的从句中； which 则不受此限制。例如：
Mummy treats me just as a baby，which （不用 as ） I can’t bear.
She married again，which （不用 as ）was unexpected.
④在宾补结构的非限制性定语从句中，作主语或宾语时，宜用 which ，而不用 as .例如：
He believed in God，which （不用 as ） I find strange.
He changed his mind，which （不用 as ） made me very angry.
⑤定语从句中动词若为表示知觉的词，如 see ，expect ，say ，know 等时，用 as 而不用 which .
As we expected / know， Xiao Ming took the first place in the game.
⑥ as 引导的定语从句与 it 作形式主语的主语从句和以 what 引导的主语从句的区别。试比较：
As is known to everybody，the moon travels round the earth once every month.
It is known to everybody that the moon travels round the earth once every month.
What is known to everybody is that the moon travels round the earth once every month.
3. 定语从句与并列句的识别。
定语从句与主句之间要用“逗号”分隔，并且不能加入 and ， but ， so 等连接词。并列句一般由 and ， but ， so 等词连接，或中间用“分号”隔开。例如：
He paid the boy $10 for washing the windows，most of which hadn’t been cleaned for at least a year. （定语从句）
He paid the boy $10 for washing the windows，and most of them hadn’t been cleaned for at least a year. （并列句）
He paid the boy $10 for washing the windows；most of them hadn’t been cleaned for at least a year. （并列句）
Recently I bought an ancient Chinese vase，the price of which was reasonable. （定语从句）
Recently I bought an ancient Chinese vase；the price of it was reasonable. （并列句）
John’s parents kept telling him that he should work hard，but it didn’t help. （并列句）
4. that 引导的定语从句与结果状语从句的区别。
This is so interesting a book that all of us want to read it. （ so …… that 引导的结果状语从句）
This is so interesting a book as all of us want to read. （ as 引导的定语从句）
通过以上两个例句不难看出， so …… that 引导结果状语从句，而定语从句中先行词前有 so ， such ， the same 修饰时，常用“ as ”来引导定语从句。
5. 定语从句与同位语从句的区别。
同位语从句是位于名词 answer ， belief ， doubt ， decision ， explanation ， fact ， hope ， idea ， information ， news ， order ， problem ， promise ， truth 等后的句子，并对这些句词进行补充说明或解释；从句一般是一个完整的句子，引导词 that 只起引导作用，不作句子成分，且 that 不可省略；同位语从句不可用 which 引导。而定语从句通常是一不完整的句子，缺少主语或宾语等。作宾语时， that 可省略。
The fact that she hasn’t known the result of the examination is clear. （同位语从句）
The fact （that / which） she told me yesterday is very important. （定语从句）

1.定语从句：定语从句是由关系代词或关系副词引导的从句，其作用是作定语修饰主句的某个名词性成分，相当于形容词，所以又称为形容词性从句，一般紧跟在它所修饰的先行词后面。2.关系词：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,as等；关系副词有where,when,why等。关系词常有3个作用：1，引导定语从句。2，代替先行词。3，在定语从句中担当一个成分。注：关系代词有主语.宾语之分。一般whom作为宾语。4.定语：定语用来限定、修饰名词或代词的，是对名词或代词起修饰、限定作用的词、短语或句子，汉语中常用‘……的’表示。主要由形容词担任。此外，名词，代词，数词，分词，副词，不定式以及介词短语也可以来担任，也可以由一个句子来担任．单词作定语时通常放在它所修饰的词之前，作前置定语。短语和从句作定语时则放在所修饰的词之后，作后置定语。
高中英语定语从句语法
定语从句是由关系代词和关系副词引导的从句,其作用是作定语修饰主句的某个成分,定语从句分为限定性和非限定性从句两种.状语从句分为时间状语从句,结果状语从句,让步状语从句,原因状语从句,条件状语从句以及行为方式状语从句.名词从句包括主语从句,宾语从句,表语从句和同位语从句及there be句型. 一、 限定性定语从句 1. that即可代表事物也可代表人,which代表事物；它们在从句中作主语或宾语,that在从句中作宾语时常可省略关系词,which在从句中作宾语则不能省略.而且,如果which在从句中作“不及物动词＋介词”的介词的宾语,注意介词不要丢掉,而且介词总是放在关系代词which的前边,但有的则放在它原来的位置 2. which作宾语时,根据先行词与定语从句之间的语义关系,先行词与which之间的介词不能丢 3. 代表物时多用which,但在带有下列词的句子中用that而不用which,这些词包括all, anything, much等,这时的that常被省略 4. who和whom引导的从句用来修饰人,分别作从句中的主语和宾语,whom作宾语时,要注意它可以作动词的宾语也可以作介词的宾语 5. where是关系副词,用来表示地点的定语从句 6. when引导定语从句表示时间 〔注〕值得一提的是,表示时间“time"一词的定语从句只用when引导,有时不用任何关系代词,当然也不用that引导 By the time you arrive in London, we will have stayed there for two weeks. I still remember the first time I met her. Each time he goes to besiness trip, he brings a lot of living necessities, such as towers, soap, toothbrush etc. 7. whose是关系代词,修饰名词作定语,相当于所修饰成分的前置所有格 8. 当从句的逻辑主语是some, any, no, somebody, anybody, nobody, something, anything, everything或nothing时,常用there is来引导 二、非限定性定语从句：非限定性定语从句的作用是对所修饰的成分作进一步说明,通常和主句间用逗号隔开,将从句拿掉后其他部分仍可成立 1. which引导的非限定性定语从句来说明前面整个句子的情况或主句的某一部分 2. 在引导限定性定语从句时,that有时相当于in which, at which, for which或at which Attitudes towards daydreaming are changing in much the same way that(in which) attitudes towards night dreaming have changed. 人们对白日做梦的态度正在改变,这与人们对夜间做梦的看法的变化有非常相似之处. I like the music for the very reason that(for which) he dislike it. 我出于某种原因喜欢这种音乐,而他恰恰与我相反. We arrived the day that(on which) they left. 刚好我们到的那天他们走了. 3. 有时as也可用作关系代词 4. 在非限定性定语从句中,不能用that,而用who, whom代表人,用which代表事物 三、定语从句结构错误 1. 缺关系词 2. 从句中缺成分 摘自《简明英语语法》 在英文中,有两种定语从句：限定性定语从句与非限定性定语从句.这两种定语从句在其功能和形式方面都有明显的区别： 限定性定语从句限定性定语从句与主句的关系很紧奏,对其先行词起限定、修饰的作用.如果将其去掉,会影响句子意思的完整性；有时甚至于引起费解、误解.例如： Rainforests are being cleared for valuable timber and other resources to speed up the economic growth of the nationsin which they are located . 为了加速他们各自所在国家的经济发展,热带雨林作为有价值的原木和其他资源正为人们所砍伐. Ocean currents affect the climates of the lands near which they flow. 洋流影响其流经的附近地区的气候. They explained the reason to us why they had hated us before. 他们向我们解释为什么他们不喜欢我们的原因. 非限定性定语从句非限定性定语从句在形式上就与主句很松散,它与主句之间有一个逗点","隔开；它对其先行词没有限定、修饰的作用,只起补充、说明的作用.有时也用它来对全句进行补充、说明.即使将其去掉,也不会影响句子意思.由于上述原因,非限定性定语从句在表达意思方面也有别于限定性定语从句.另外,非限定性定语从句在中文译文里,我们往往将其作为一个分句处理,而不把它作定语翻译. 例如：Earlier , the Babylonians had attempted to map the world , but they presented it in the form of a flattened disc rather than a sphere , which was the form adopted by Ptolemy . （此句中,非限定性定语从句是对先行词a sphere进行补充、说明.） 更早之前,巴比伦人曾试图绘制世界地图,但是他们把它绘制成平盘状而不是托勒密所采用的球体状. The bination of satellites, which tran *** it information , puters , which store information , and television , which displays information , will change every home into an education and entertainment center . （此句中,三个非限定性定语从句分别对三个先行词：satellites ,puters和television进行补充、说明.如果去掉这三个非限定性定语从句,那么句子可简化为： The bination of satellites , puters and television will change every home into an education and entertainment center .）卫星能传输信息,计算机能储存信息,电视能显示信息,把这些手段结合起来可以使每个家庭都成为教育娱乐的中心. The sun heats the earth , which makes it possible for plants to grow .（此句中,非限定性定语从句是对全句进行补充、说明,将全句表达的意思看成"一件事情）.太阳给予大地热,这就使植物的生长成为可能. The old man has a son , who is in the army .（此句中,非限定性定语从句是对先行词son进行补充、说明.但本句所传达的信息是："这位老人只有一个儿子" .如果将此句改写成限定性定语从句： The old man has a son who is in the army . 那位老人有一个在部队工作的儿子.那么,限定性定语从句就要对先行词son进行限定、修饰.这样一来,句子所传达的信息就变成了："这位老人有一个儿子在部队工作,还有其他的儿子在干别的工作".）那位老人有一个儿子,他在部队工作.

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。 .

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。 . 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。 . 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。 . 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。 .

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。 .

定语从句是高中英语第一大语法内容，必须清晰掌握。接下来我为大家整理了高一英语学习的内容，一起来看看吧!
高一英语重点语法--定语从句
01
定语从句基本概念
在复合句中，修饰名词或代词的从句叫定语从句。
引导定语从句的词叫关系词。
被修饰的名词或代词叫先行词。定语从句一般放在先行词的后面。
02
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)，as 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。
03
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。
1. 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。例如：
Any man that / who has a sense of duty won’t do such a thing.
任何有责任感的人都不会做这样的事。
2. 非限制性定语从句主句与从句之间有逗号分开，起补充说明作用，如省去，意思仍完整。例如：
The house,which we bought last month,is very nice.
这幢房子很漂亮,是我们上个月买的.
注意：非限定性定语从句中不能使用关系代词 that。
04
关系代词的用法
1. that
that既可以用于指人，也可以用于指物。在定语从句中作主语、宾语或表语，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)
The coat (that) I put on the desk is blue.
我放在桌子上的那件外套是蓝色的。(that作宾语)
2. which
which 用于指物，在句中作主语、宾语或表语，作宾语可省略。例如：
The building which stands near the train station is a supermarket.位于火车站附近的那座大楼是一家超市。(作主语)
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
who， whom 用于指人，who 用作主语和表语，whom用作宾语。在口语中，有时可用who代替whom，也可省略。例如：
The girl who often helps me with my English is from England.
经常在英语方面帮助我的那个女孩是英国人。(who 作主语)
Who is the teacher (whom) Li Ming is talking to?
正在与李明谈话的老师是谁?(whom 作宾语)
4. as
① 引导限定性定语从句时，指与先行词相似的人或物，必须用于 such/so...as...或 the same...as...结构中，例如：
Such people as were mentioned by him were honest.
被他提到的这样的人是诚实的。
Last term our maths teacher set so difficult an examination problem as none of us worked out.
上学期我们数学老师出了一道我们没有一个人会的数学题。
This is the same bag as I lost yesterday.
这是和我昨天买的包一样的包。
② 引导非限定性定语从句时，只能修饰句子，可置于被修饰句子后面、前面或主谓之间,翻译成“正如...那样”例如：
The earth moves around the sun, as we all know.
As we all know,The earth moves around the sun.
The earth, as we all know, moves around the sun
③ 在非限制性定语从句中，which和as引导定语从句时的区别：
a. which引导的从句不能放在主句前，而as引导的从句则既可以放在主句前，也可以放在主句后，还可以放在主谓之间。
b. as和which都可以指代一个句子，但as有“正如”、“就像”之意，which则没有此含义。
c. as 引导的非限定定语从句只能修饰句子，which 引导的非限定性定语从句可以修饰句子，也可以修饰名词。
注意：
1. 当定语从句中含有介词，介词放在句末时，who，whom, that，which可省略，但介词在关系代词前时，只能用“介词+which/whom”结构。例如：
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。
2. 含有介词的固定动词词组中，介词不可前置，只能放在原来的位置上。例如：
This is the person whom you are looking for.
这就是你要找的那个人。
3. 关系词只能用that的情况：
① 先行词被序数词或形容词最高级所修饰，或本身是序数词、形容词最高级时，只能用that，而不用which.例如：
He was the first person that passed the exam.
他是第一个通过考试的人。
当先行词指人时，偶尔也可以用关系代词who。
② 被修饰的先行词为all， any， much， many， everything， anything， none， the one等不定代词时，只能用that，而不用which.例如：
Is there anything that you want to buy in the shop?

高一英语教你学会做英语笔记
1、注音标(Phonetics)，标重音(Stress)。
每单元的英语课文都有不少生词、一词多音和容易读错的英语单词，某些英语单词作名词和动词的发音不同，如'record(n.)和re'cord(vt.)。将英语音标和重音记在被注的单词上边，并要求学生在朗读课文时重视所注的音标和重读音节。这样，一旦课文读熟,那些单词的正确读音也就熟记在心了。
2、释义(Paraphrase)。
英语中有不少生词、多义词、短语、习惯语和难句需要用简单的英语或汉语来解释。如：quarrel争吵(to argue or disagree angrily with someone);forture财富(great wealth)。在课文学习过程中，注释的重点是一些较难的名词、短语和重点句型，而不必每个句子都解释。注释文字书写位置的原则是“就近”，即尽可能记在被解释的单词旁边，以便在阅读课文时被注视。若解释的英文单词较多，原文旁边写不下或记下去因单词太多书写太密而不清晰时，可记在相对较近的空白处，注释文字与被注文字之间可划一直线连接。也可记录在词汇表中该单词的后面。
3、划重点(Language Points)。
我指导学生用五角星标出新句型、用三角形标出旧句型、用圆圈标出介词或冠词、用方框标出新的短语和词组、用直线或水浪曲线划出英语课文中的关键句，科普文、议论文中表明作者中心论点的句子。语法和练习中的一些重点、难点也该划出来，以便引起重视。4、提要(Guideline)。
即用简洁的英文概括提示课文或段落、或句子的要点。这一工作常常与上述几项结合起来进行，先在原文上作上线条、小圆圈之类的标记，再在旁边空白处写上要提示的文字。例如，现在使用的高中英语教材每一单元阅读课文的正文前面都有“预习提示”(包括课文的重点生词和要讨论的问题)，课文的后面常要求学生作简要笔记Note Making ;这是教材编辑为方便学生预习而编写的内容。我要求学生在自学课文时，先从这些“预习提示”入手，以便把握预习的重点。然后再根据“提示”去预习正文。如高二(下)第十四单元Satellite(卫星)是一篇科普文章，学生可以根据“预习提示”和Note Making把课文分为四个段落，我指导学生在各段落旁分别写上Broadcasting satellite(广播卫星),Weather Satellite(气象卫星),Communication Satellite(通讯卫星),Space Satellite(太空卫星)。这样，“预习提示”所述的课文要点就概括、凸现出来了，课文的段落大意和中心思想也一清二楚了。
4、标疑(Question)。
英语不是我们的母语，因此，在英语学习过程中，我们常常会碰到许多问题。阅读过程中可以在有问题的地方打一个问号，再寻找机会向老师或同学求教或查阅有关参考书解疑。
5、分析难点(Comprehension)。
学生阅读英语课文，不断会遇到一些难点，经过老师的讲解，或与同学一起讨论有些可能当场已经完全理解，有的还似懂非懂。不管怎样，边听边记下析难的文字，既有利于课后消化，也有利于复习回顾。
6、补缺(Replenishment)。
英语词汇表和一些参考书中对某些单词和词组的解释不够全面，有些只讲了名词的意思，而未说明作动词、形容词等的意义。老师应该让学生自己查词典或告诉他们别的用法，并让他们记录下来。比如学习了名词success(成功),应该让他们记下形容词successful、副词successfully和动词succeed。
7、纠错(Correct Mistakes)。
英语定从解析
定语从句定语从句是修饰名词或代词的从句叫定语从句，被定语从句所修饰的名词或代词叫先行词。(1)由That引导，(指人或物)，先行词是人或物(2)由Who引导(指人)先行词是人(3)由Which引导(指物)先行词是物(1)和(2)例:Thisistheengineerthatwhowillgiveusatalk.特殊情况:引导词只能用That而不能其他《1》被序数词或者是最高级修饰的先行词后边，只能用That.用“《》”的说明只能用这个词例:Thisisthemostinteresingstory《that》Ihaveeverread.例:XiaoMing(小明)isthefirstforginer《that》Ihaveknown.《2》先行词是不定代词的必须用That(2)定语从句中的胃语动词形式要与先行词的人称和数保持一致。(这里所说的数是单数或复数形式要与第几人称一致)
1、选A，这不是个定语从句，而是个同位语从句，that 引导的从句做point 的同位语，in her career 在这儿只是个状语2、C，因为the factory 在从句中做visited 的宾语，A、B、D都只能做状语3、A，当先行词有the first 等限定时，关系词用that4、c 5、D,应该是the larger of which
我会在讲解的内容里面穿插一些下窍门，就算是告诉你怎样学。1.d 所谓定语从句，也就是说这个从句在句子中的左右是定语。那么，定语需要有修饰词，这个修饰词在这儿特别地叫作先行词。好了，定语从句第一步：我们要找到先行词，结合例子:After graduation,she reached a point in her career（where）she needed to decide what to do.这里的先行词是什么呢？这就没有窍门了，只有自己琢磨，靠语感。这里的先行词是point。到这里为止，所讲的和为什么要选where没有一点关系。那么为什么要选d呢？定语从句第二步：看从句里面少什么：she needed to decide what to do.这里缺什么呢？主谓宾还带了宾语从句（不定式作宾语）。要来也就只有状语了（附加知识：状语是英语里面附着性最弱的。）好了，到此为止，第一题讲完了。2.cvisit是及物动词，缺宾语3.asee是及物动词。照这个分析法，貌似ab都可以，这就是定语从句的语法规则：句子里有序数词、最高级等时，只能用that(不止这两种，你可以上网去查一下)4.c这个是定语从句特殊用法，记住。（same..as中as直接带）另外也可以这样看：根据句意，你教室里面那台电视很明显是你们在用着，所以我就不可能再用了，我只能是用和你那台一样的。5.d (你这里可能打错了，应该是larger)如果中间是句号，那么a也可以（其实，定语从句几乎都可以拆成两句）。英语句子连接性很重要，不能像汉语那样形散意合，所以要缀一个which指向前面。对了，这句不选c的原因也是定语从句的语法规则，非限定性定语从句只能用which。
1B 从句是一个完整的句子，各成分都够所以用that来引导从句。2C 从句缺少宾语，把从句的主语和谓语提出来“he visited”，然后再组成一个陈诉句，就不需要介词，就排除B和D，而“where”可以分拆为介词加一个代词，所以也排除，就选C3和4有限定词“the first、the same”所以可以直接选择，你们应该专门记了这个关于限定词的东西，但是我忘了，你翻翻笔记就出来了，呵呵，不好意思5D，首先既然是从句，排除AC,然后定语从句没有用them的，所以直接选D，这题很典型，你可以直接背下来，这类题全部选the ** of which.答案不全，但是希望可以帮到你，你应该是个很用功的学生，希望学习进步，我回去查查我的笔记再看看。
