用来说明主句中某一名词或代词(有时也可说明整个主句或主句中一部分)而起定语作用的句子叫作定语从句。

一.词引导的定语从句1. 关系代词用来指代先行词是人或物的名词或代词句子成分用于限制从句或非限制性从句只用于限制性从句代替人代替物代替人或物主语Who which that主语Whom which that宾语Whose(=of whom) whose(=of which)例1：This is the detective who came from London.例2：The book which I am reading is written by Tomas Hardy.例3：The desk whose leg is broken is very old.例4：This is the room that Shakespeare was born in.2.关系代词的用法(1) 如果先行词是all, much, anything, something, nothing, everything, little, none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, some, 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。

1，You are my sunshine.I get up at six o’clock this morning.She and my borother will get married next month.2, They speak English, and we speak Chinese.He got up last, so he missed the bus.3, Please tell me who is your teacher.I don't know why he is crying.定语：ten mimutes five people your umbrella the most popular subjuect Nina’s cat定语——定语从句：The fiilm that we saw yesterday is interesting.I know the man who spoke to you just now.先行词关系代词关系副词They planted some trees which didn’t need much water.The fish (which) we bought this morning were not fresh.which 不指人，在从句中做主语和宾语，做宾语时可以省略。

在从句中做主语和宾语，做宾语时可以省略。

I know the man who spoke to you just now.The woman who is crying is my teacher.The man whom you saw yesterday is my father.who/ whom 先行词表示某人时，用who。

英语三大从句在英语中,主要有三大从句,即名词性从句包括主语从句,宾语从句,表语从句,同位语从句、形容词性从句即定语从句、副词性从句即状语从句,包括时间、条件、结果、目的、原因、让步、地点、方式等;定语从句一、关系代词引导的定语从句关系代词代替前面的先行词,并且在定语从句中充当句子成分,可以作主语、宾语、定语等;常见的关系代词有：who, that, which;它们的主格、宾格和所有格如下表所示：一关系代词who, whom和 whose的用法who代替人,是主格,在定语从句中作主语;An architect is a person who designs buildings. 建筑师是设计房屋的人;whom代替人,是宾格,在定语从句作宾语,在非正式英语常可省略;Do you know the gentleman whom we met in the school library yesterday 昨天我们在学校图书馆里遇到的那位先生你认识吗whose一般代替人,有时亦可代替物,是所有格,在定语从句作定语;The girl student whose father is a senior engineer used to study abroad. 其父是一位高级工程师的那个女学生过去在国外留学;Do you know the name of the hotel whose window we can see here 我们这儿能看到窗户的那个宾馆叫什么名字,你知道吗关系代词whose指代先行词hotel,正式用法应该用of which;whose window=the window of which,意思是：the window of the hotel;二关系代词which的用法which代替物,在定语从句作主语或宾语,作宾语时还可省略;I do not like stories which have unhappy endings.我不喜欢有不幸结局的小说;which可以换成that三关系代词that的用法that既可指人又可指物,在当代英语中大多指物,在定语从句作主语或宾语,作宾语时还可省略;： Is she the girl that sells newspapers她是卖报纸的那个女孩吗that可以换成whoWhere is the ice-cream that was in the fridge放在冰箱的冰激凌哪儿去了that可以换成whichIs this the book that you want to buy这是你要买的那本书吗 that可以换成which,在定语从句作宾语,还可以省略二、关系副词引导的定语从句常用的关系副词只有三个：when, where, why,在定语从句中充当时间、地点和原因状语;一关系副词when的用法关系副词when代替的先行词表示的是时间,when在定语从句作时间状语;In Beijing July and August are the months when it rains very often.北京的七月和八月是常下雨的月份;when先行词是months二关系副词where的用法关系副词where代替的先行词表示的是地点,where在定语从句作地点状语;During the Spring Festival I went back to the town where I was brought up.春节期间,我回到了生我养我的家乡;where的先行词是town三关系副词why的用法关系副词why代替的先行词表示的是原因,why在定语从句作原因状语;The reason why I am phoning you is to ask you whether you have got my email.我打电话给你的原因是想问问你是否收到了我的电子邮件;why先行词是reason, 当代英语里why可以用that替代,这时关系代词that就变成了表示原因的关系副词,还可以将why省略三、特殊关系代词as引导的定语从句一在固定搭配as…as, so…as, such…as, the same…as中,as引导定语从句You may take as many books as you want.你想要拿多少书就拿多少;第一个as是副词,修饰many的；第二个as才是关系代词,代替先行词books,在定语从句中作宾语二独立于主句之外,as引导定语从句As we know/ As is known to us, the earth turns around the sun. 正如我们所知,地球围绕太阳旋转;As we know和 As is known to us均为定语从句,as分别作宾语和主语,替代后面的主句;Taiwan is, as you know, an inseparable part of China.你知道,台湾是中国不可分割的一部分;关系代词as指代整个主句,在定语从句中作宾语;四、关系代词who, which与that的区别一关系代词who与that的区别1. 当关系代词用作主语时,多用主格who;He who loses hope loses all.失去希望的人就失去一切;先行词为代词he, they, any, all, one等时,多用whoI met Alice, who told me that she was learning Chinese.我遇见艾丽斯,她告诉我她在学汉语;在非限制性定语从句中,用who2. 当关系代词用作介词后的宾语时,用宾格whom,不用that;The man to whom our headmaster talked just now is our English teacher.我们校长刚才与他谈话的那个人是我们的英语老师;介词与关系代词紧密相连时,只能用宾格whom,不可用主格who注意：介词与关系代词不是紧密相连时,或者说介词放在句子后面时,这时可以用主格who,也可用that,还可以省略关系代词;因此,上面的这句话还可以有如下四种说法：1 The man whom our headmaster talked to just now is our English teacher.2 The man who our headmaster talked to just now is our English teacher.3 The man that our headmaster talked to just now is our English teacher.4 The man our headmaster talked to just now is our English teacher.3. 当关系代词泛指人时,多用that;He is a man that is never afraid of failure.他是个从不怕失败的人;that用来泛指人4. 当关系代词出现在who开头的疑问句时,应用that;例如：Who is the girl that is talking to Tom in English用英语同汤姆交谈的那个女孩是谁避免重复使用who,以免造成误解或语义含混不清二关系代词which与that的区别1. 当先行词为all, much, little以及不定代词anything, something, everything等时,关系代词多用that;All that glitters is not gold. 闪闪发光物,未必尽黄金;She told me everything that she knew. 她把她所知道的一切都告诉了我;2. 当先行词的前面有形容词最高级、序数词或限定词the only, the very, all, every, any, no 等时,关系代词一般都用that;This is the best novel that I have ever read. 这是我读过的最好的一部小说;He is the only person that has been invited to the ball. 他是惟一应邀参加舞会的人;3. 当关系代词出现在which开头的疑问句时,应用that;Which was the hotel that was recommended to the foreign guest 哪一个是推荐给外宾的宾馆这里使用that很明显是为了避免重复which4. 在非限制性定语从句中,关系代词一般只用which;Beijing, which is the capital of the People’s Republic of China, will host the 2008 Olympic Games. 北京是中华人民共和国的首都,将主办2008年奥运会;5. 介词后的关系代词用which,而不用that;She has collected 600 stamps, 60% of which are German stamps. 她收集了600张邮票,其中60％是德国邮票;五、定语从句的位置如前所述,定语从句一般总是直接置于所修饰的名词或代词之后;有时候,定语从句与先行词之间插入了其他的短语,这样它们被分隔了,这种情况下的定语从句被称作隔离定语从句;There was a girl upstairs who was shouting and crying, obviously mad.楼上有一个女孩,大喊大叫;很明显,她疯了;定语从句who was shouting and crying修饰the girl,被upstairs所隔开A new master will come tomorrow who will teach you German.明天要来一位新老师教你们德语了;定语从句置于句末以示强调名词性从句宾语从句一、引导词1由that 引导的陈述句性的宾语从句,在很多动词如say, think, wish , hope, see, believe, agree, expect, hear , feel等动词后;连词that只起连接作用,在从句中不做句子的成分,也无词汇意义,在口语中常被省略;如：I told him that he was wrong.在think, believe, suppose, expect等动词引起的宾语从句中,有时谓语尽管是否定意义,却不用否定形式,而将think 等动词变为否定形式;见语法：否定转移如：I don’t think you are right. 我认为你做的不对在许多带有复合宾语的句子中,that引导的宾语从句经常移到句子的后面,而用it做形式宾语;We think it wrong that he told a lie to everyone 我认为他向每一个人撒谎是错误的2 由连词if、 whether 引导的表示“是否…”的宾语从句;Whether, if 在从句中不做句子的成分,一般情况下,whether和if 可以替换;I don’t know if/whether he will come tomorrow.在介词后面的宾语从句中不用if引导Everything depends on whether we have enough money.宾语从句中有or not时不用if引导.I don’t know whether the movie star will come or not.和不定式连用作宾语时不用if引导Whether to go there or not hasn’t been decided.3由wh-引导的宾语从句;连接代词who, whom, whose, what, which和连接副词when, where, why, how 等连接的宾语从句,它们在句中即有连接从句的作用,又在句中充当句子的成分;Do you know which film they are talking about which做定语I don’t know where he lives. where 做地点状语二、宾语从句的语序,宾语从句的语序必须是陈述语序,既连接词+主语+谓语+其他成分 I believe that they will come soon.特例：有下列常见的问句,作为从句出现,是“不改变语句顺序”的;1. What's the matter2. What's wrong3. What's up4. What's the problem5. What's your trouble三、宾语从句的时态;宾语从句的时态受主句的限制,即：主句是一般现在时态,从句根据实际情况而定；主句是一般过去时态,从句用相应的过去的时态;如果从句的动作发生在主句之前,则从句要用过去完成时态;1 She says that she is a student.→ She said that she was a student.2She says that she will fly to Japan in a week. → She said that she would fly to Japan in a week.3She says that she has finished her homework alre ady. → She said that she had finished her homework already.1如果宾语从句说的是客观真理、自然现象或事实时,这时宾语从句要用一般现在时态;The teacher said that the earth goes round the sun.2Could you tell me…是用来征询对方的意见,语气委婉,并不表示过去;Could you tell me when we will visit the History Museum注意事项：3由陈述句变成宾语从句时,要注意人称的变化;She said: “I have been to England before.” → She said that she had been to England before. She asked me: “Do you like maths” → She asked me if I liked maths.4宾语从句与简单句的交换;由连接代词和连接副词引导的宾语从句,如果宾语从句的主语和主句的主语是同一个人时,可以用“疑问词+不定式”做宾语的简单句结构;I don’t know what I should do next. → I don’t know what to do next.DO SOME EXERCISES:you see AA. what he’s readingB. what is he readingC. what does he readD. he reads what2.

Why is our Chinese team be able to beat Korea同位语从句一一般来说,在主从复合句中,用作同位语的从句叫同位语从句;它通常跟在某些名词之后,用以说明或解释该名词表示的具体内容;可以跟同位语从句的名词通常有：advice, decision, fact, hope, idea, information, message, news, promise, proposal, reply, report, suggestion, word消息,problem, question, doubt, thought等;eg: They were delighted at the news that their team had won.当听到他们队获胜的消息时,他们欣喜若狂;有时同位语从句可以不紧跟在被说明的名词后面,而被别的词隔开; 如：The thought came to him that Tom might have returned the book.他突然想起汤姆可能已经还了书了;二引导词1. The news that Mr. Li will be our new English teacher is true.2. He hasn’t made the decision whether he will go there.3. The question who should do the work is being discussed at the meeting.4.

I have no idea how I can get to the railway station.7. I have no idea when he will be back．小结：① that引导同位语从句时无词义,也不充当任何成分,但通常不可以省略,如句1；② whether引导同位语从句时意为“是否”,通常不能用if来代替, 如句2;③ 连接代词who, what等可以引导同位语从句,如句3, 4；④ 连接副词where, how, when等可以引导同位语从句, 如句5,6,7;三 that 引导的同位语从句和定语从句① 意义不同：同位语从句用来进一步说明前面名词的内容；而定语从句用来修饰、限定前面的先行词;试比较：1. The news that our team has won the final match is encouraging.2. The news that you told us is really encouraging.② that的功能不同：that引导同位语从句时是一个纯连词,不充当任何成分；而引导定语从句时,不仅起连接作用,而且还指代先行词并在从句中充当主语、宾语等成分;试比较：1. Dad made a promise that he would buy me a CD player if I passed the English test.2. Dad made a promise that excited all his children.③ 可否省略：that在引导同位语从句时,通常不可省略;在引导定语从句时,若在从句中作宾语,通常可以省略,若作主语则不可以省略;DO SOME EXERCISES:I. 请用适当的词填空,使下列句子意思完整;1.

One of the men heldthe opinion when what the book said was right.表语从句表语从句只能置于主句之后,而主句的动词只能是连系动词;名词性从句在be等系动词后作表语时被称为表语从句The problem is how we can get the things we need.问题是我们怎样能弄到我们需要的东西;how 在表语从句中充当方式状语The scissors are not what I need. 这把剪刀不是我所需要的;what 在表语从句中充当宾语What I told him was that I would find him a good play. 我告诉他的是我会给他找个好剧本;what 在主语从句中作直接宾语, that作为表语从句的引导词在该表语从句中不充当句子成分, 不能省略That is what I want to tell you.那就是我想要对你讲的;what在表语从句中充当直接宾语That is why she failed to pass the exam. 那就是她考试不及格的原因;why 在表语从句中充当原因状语“That is why...”是常用句型, 意为“这就是……的原因/因此……”, 其中why引导的名词性从句在句中作表语, 该句型通常用于针对前面已经说明过的原因进行总结下面是两个与“That is why...”形式相似的结构, 它们与“That is why...”结构之间的关系要能够辨析清楚：1“That is why...”与“That is the reason why...”同义, 只不过从语法结构上讲, “That is the reason why...”中why引导的是—个定语从句, 将其中的the reason去掉则与“That is why...”结构一样 That is the reason why I cannot agree.2“That is because...”句型中从属连词because引导的名词性从句在此作表语, 这也是个常用句型, 意为“这就是为什么……/因为……”;“That is because...”与“That is why...”之间的不同在于“That is because...”指原因或理由, “That is why...”则指由于各种原因所造成的后果He did not see the film last night. That is because he had to help his little sister with her homework.昨天晚上他没有去看电影, 那是因为他得帮助他的妹妹做作业;第一句话说明结果, 第二句话说明原因He had seen the film before. That is why he did not see it last night.他以前曾看过那部电影, 因此他昨天晚上没有去看;第一句话说明原因, 第二句话说明结果考题1The traditional view is ____ we sleep because our brain is “programmed” to make us do so. 2007上海A. whenB. whyC. whetherD. that考题2You are saying that everyone should be equal, and this is ____ I disagree. 2004A. whyB. whereC. whatD. how考题3— I drove to Zhuhai for the air show last week.— Is that ____ you had a few days off 1999A. whyB. whenC. whatD. where考题4____ made the school proud was ____ more than 90% of the students had been admitted to key universities. 2003上海春A.

定语从句引导词及⽤法 定语从句中会有引导词，那么定语从句引导词有哪⼀些呢?以及他们的⽤法⼜是什么呢? 1. 关系代词有：that,which,who,whom,whose,在定语从句中作主语、宾语中表语，whose作定语。

代⼈的有：who,whom,whose,that;代物的有：that,which,whose.例如： The man who helped you is Mr White.(who代⼈，在定语从句中作主语) That is the person(whom/who/that) you want to see.(whom,who,that代⼈，在定语从句中作宾语，可省略) Im not the fool(that) you thought me to be.(that代⼈，在定从中作表语) A dictionary is a useful book which(=that) tells us the meaning of words(which或that代物，在定从中作主语) 2. 关系副词有：when(指时间)，where(指地点),why(指原因)，在定语从句中作状语。

例如：Would you suggest a time(when) we can have a talk?(when可省略) The house where they live is not very large./This is the reason why he did not came to the meeting. 注意：不是表时间的先⾏词都⽤when引导定从，不是表地点的先⾏词都⽤where引导定从。

例如：Well visit the factory which(=that) makes radios. (which或that在定从中作主语，where不可⽤主语，故不可⽤) They still remember the happy days(which/that) they spent in Beidaihe. (which或that在定从中作spent的宾语，when不可作宾语，故不可⽤) 定语从句引导词及⽤法 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。

英语定语从句的结构和用法定语从句的结构：定语从句通常包括三个部分：引导词、主句和从句。

1. 引导词：定语从句的引导词通常由关系代词和关系副词构成。

2.主句：主句是指引导词所修饰的名词所在的句子。

3.从句：从句是由引导词引导的从句，用来修饰主句中的名词。

定语从句的用法：1. 修饰人：从句中用who或that引导。

- The man who is standing over there is my brother.- The woman that I met yesterday is a famous actress.2. 修饰物：从句中用which或that引导。

- The book that is on the table is mine.- The car which/that I bought last week is very expensive.3. 修饰地点：从句中用where引导。

4. 修饰时间：从句中用when引导。

- I still remember the day when we went to the beach together.5. 修饰原因：从句中用why引导。

6. 修饰所有格：从句中用whose引导。

- The boy whose father is a doctor is my classmate.需要注意的是，定语从句通常紧跟在被修饰的名词或名词短语之后，并且从句中的主语一般不可以省略，而宾语可以省略，具体要根据具体情况来确定。

同时，引导词在从句中所起的作用与其在主句中的作用相同，例如，关系代词在从句中可以充当主语、宾语、定语等。

定语从句定语从句（Attributive Clauses）在句中做定语，修饰一个名词或代词，有时也可以修饰部分或整个句子。

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，as 。

关系副词有：when, where, why ,how 。

关系代词和关系副词放在先行词和定语从句之间，起连接作用，同时又可做定语从句的一个成分。

当关系代词做宾语时可以省略。

定语从句中的谓语动词必须在人称上和数量上和先行词保持一致。

定语从句分为限制性定语从句和非限制性定语从句。

1 、关系代词引导的定语从句1）who, whom, that这些词代替的先行词是人的名词或代词，在从句中所起作用如下：Is he the man who/that wants to see you?（who/that在从句中作主语）He is the man whom/ that I saw yesterday.（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. Please pass me the book whose (of which) cover is green.3)which, that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，例如：A prosperity which / that had never been seen before appears in the countryside.（which / that在句中作宾语）The package (which / that) you are carrying is about to come unwrapped. (which / that在句中作宾语)关系代词that和which 都可以指物，that 和Who 都可以指人，其用法区别：1）不用that的情况a) 在引导非限定性定语从句时(错) The tree, that is four hundred years old, is very famous here.b) 介词后不能用We depend on the land from which we get our food.c)多用who 的情况①关系代词在从句中做主语A friend who helps you in time of need is a real friend .②先行词为those , people 时Those who were either fools or unfit for their offices could not see the cloth .③先行词为all, anyone , ones , one 指人时One who doesn’t work hard will never succeed in his work .④在There be句型中There is a stranger who wants to see you .⑤在被分隔的定语从句中A new teacher will come tomorrow who will teach you German .⑥在有两个定语从句的句子中，其一用who,其二用that,但若先行词后接两个以上的并列定语从句时，后一个必须重复前一个关系代词。

定语从句中关系词的使用▼关系词：关系代词：who, whom, that, which, whose关系副词：where, when, why▼关系代词的使用：一、who/ whom的用法二者都可指人，who在定语从句中作主语、宾语，whom在定语从句中作宾语→In this accident, the number of people who died reached as many as 25. 在这次事故中死亡人数多达25人。

→I have many friends to whom I am going to send postcards. 我要寄给很多朋友贺卡。

注意：①在限制性定语从句中作宾语的关系代词whom也可用who代替，非限制性定语从句中，whom不可用who代替；②但介词提前作宾语时不可以用who，只能用“介词+whom”。

例：→The person to whom you just talked is Mr Li.二、whose的用法Whose一般指人，有时也指物，在定语从句中作定语→You’re the only one whose advice he might listen to.只有你的建议他可能会听。

（whose在定语从句中作advice的定语）→I’d like a room whose window looks out over the sea.我想要一个窗户朝向大海的房间。

（whose在从句中作window的定语）三、which的用法Which一般指物，在定语从句中作主语、宾语，偶尔也作定语。

Which 在指人时往往指婴儿或指人的品质→The river which runs through the center of the city was polluted seriously.穿过市中心的那条河遭到了严重的污染。

（which在从句中作主语）→They stayed with me for three weeks during which time they drunk all thewine I had.他们和我一起待了三周，这期间他们喝光了我所有的酒。

1、定语从句的定义在复合句中,修饰某一名词或代词用作定语的从句叫作定语从句。

被定语从句修饰的词叫先行词,定语从句必须放在先行词之后。

引导定语从句的关系词有关系代that,which,who,whom, whose和as以及关系副词when, where和why等。

关系代词在定语从句中可用作主语、宾语、定语等;关系副词在定语从句中作状语。

2、定语从句引导词的用法(1)that的用法that的先行词是人或物,在定语从句中作主语、宾语或表语。

例子 A computeris a machine which can do many things for us.电脑是一种可以为我们做许多事情的机器。

定语从句that和which、who（whom）用法定语从句that和which、who(whom)用法定语从句，一个简单句跟在一名词或代词后（先行词）进行修饰限定，就叫做定语从句。

下面是店铺为你带来的定语从句that和which、who(whom)用法，欢迎阅读！定语从句that和which、who(whom)用法1that和which的用法区别:在定语从句中，关系代词which和 that都可指物，一般情况下，可以互换使用。

但在下列情况下值得注意：A. 只能用that而不能用which的情形(1) 当先行词为：all, little, few, much, none 及 some-, any-, no-, every- 与 thing 所组成的复合单词时，只能用that。

如：There is nothing that will stop us making progress. 没有事情会阻止我们进步。

(2) 当先行词前面有only, some, any, no, every, little, few, much, all, very等形容词修饰时，只能用that。

定语从句详解：who、whom、whose、which、that引导的定语从句一、定语从句基本概念定语从句通常在英语复合句中充当定语的作用，在简单句中，定语往往用来修饰代词、名词或名词性短语,例:Tom is a handsome boy. Tom是个英俊的男孩。

There is a good boy. 有个乖男孩。

将以上的两句转换为定语从句则为：Tom is the boy who is handsome.There is a boy who is good.二、定语从句中两大要素了解了定语的作用之后，现在进入定语从句的正式学习。

想要辨别定语从句，必须了解定语从句的两大要素：关系代词(或关系副词)、先行词。

本节重点讲解由关系代词引导的定语从句，下一节将为大家带来关系副词引导的定语从句。

首先为大家简单例举一个定语从句。

He is a good person who would like to help anyone. 他是一个好人，肯帮助任何人。

其中person就是先行词，who则为关系代词who是用来指代这个先行词person，因此称为关系代词。

此外，who 只能做“人”关系代词，比如boy、girl、people等。

除了who之外，关系代词还有whom、whose、which、that其中，值得注意的是，当定语从句修饰一个“人”时，选择关系代词必须了解先行词在从句中的位置才能做出决定，我们可以用拆分复合句的方法来判断。

例：1.He is a good person who would like to help anyone. 他是一个好人，肯帮助任何人。

拆分后：He is a good person.The person would like to help anyone.拆分后可以发现，先行词在第二句中做主语，因此用who.2.He is the man whom I met yesterday.拆分后：He is the man.I met the man yesterday.拆分后可以发现，先行词在第二句中做宾语,因此用whom.当需要使用修饰“物”的关系代词时，例句是这样的：1.This is a car which(that) is red.拆分后:This is a car.The car is red拆分后发现，先行词在第二句中做主语.2.This is the book which you gave me yesterday.拆分后：This is the book.You gave me the book yesterday拆分后发现，先行词在第二句中做宾语3.This is the room in which you were born.拆分后：This is the room.You were born in the room拆分后发现，先行词在第二句中做宾语。

不定代词的用法关系代词who,whom,whose,that,which的用法1 关系代词who,whom,whose,that,which的用法英语中的关系代词有who,whom,whose,that,which,它们是用来引导定语从句的.关系代词既代表定语从句所修饰的词,又在其所引导的从句中承担一个成分,如主语、宾语、表语或定语.如：A child whose parents are dead is an orphan.失去父母的孩子是孤儿.whose在从句中作定语,它的先行词是childHe wants a room whose window looks out over the sea.他想要个窗户面临大海的房间.whose在从句中作定语,它的先行词是roomThis is the man who saved your son.这就是救了你儿子的那个人.who在从句中作主语,先行词是manThe man whom I met yesterday is Jim.我昨天见到的那个人是吉姆.whom在从句中作宾语,它的先行词是man[1] who,whom和whosewho和whom代表人,在从句中作主语时用who,作宾语时用whom,可省略.但若whom作介词宾语且介词放在其前时,不能省略;如介词位于句末时,可以省略.whose代表某人的,在从句中作定语.如：The man who insists upon seeing with perfect clearness before he decides,never decides.坚持看清楚一切后才做决定的人永远也做不了决定.who作主语He is a man whom everybody respects.他是一个人人都尊敬的人.whom作宾语,可以省略He is a man fromwhom we all should learn.他是我们大家都应该学习的人.whom作介词宾语且介词位于其前,不能省略此句也可以是：He is a man whom we should all learn from.The people whose houses were damaged will be compensated.房子被损坏了的人将给予补偿.Who,whom和whose可用于非限制性定语从句中,代表某人或某人的,此时不能用that.如：My sister,who is a nurse,came home for a few days.我姐姐回家住了几天,她是个护士.[2] whichwhich代表物,在从句中可作主语或宾语,作宾语时可以省略,但作介词宾语且介词位于其前时不能省略.如：The book which helps you most are those which make you think most.最能使你获益的书是那些最能让你深思的书.作主语This is a factor which we must not neglect.这是一个我们绝不能忽略的因素.作宾语,可省略Where is the book from which you quoted this sentence?你引用这句话的那本书在哪儿?作介词宾语且介词位于其前时,不能省略which可用于非限制性定语从句中,代表物.如：The book,which I bought second-hand,is made of oak.我买的这张书桌是用橡木做的,它是二手货.[3] thatthat可以代表事也可代表人,在从句中可以作主语或宾语,作宾语时可省略,但不能用于非限制性定语从句中.代表人时who比that用的多些,代表物时that比which用的多些.如：The letter that came this morning is from my mother.今天早晨收到的那封信是我母亲寄来的.that代表物,在从句中作主语Those students that failed the exam will have to take it again.考试不及格的学生必须补考.that代表人,在从句中作主语Have you forgotten about the money that I lent you last week?你忘了上星期我借给你钱的事了吗?that代表物,在从句中作宾语,可省略All the people that I invited have agreed to come.所有我邀请了的人都同意来.that代表人,在从句中作宾语,可省略The hotel that we stayed at was both cheap and comfortable.我们住的那家旅馆既便宜又舒服.that代表物,在从句中作介词宾语,可省略2 补充说明下列情况下,定语从句的关系代词只能用that,不能用which或who[1] 当先行词中有形容词的最高级时.如：Shakespeare is the greatest poet that English has ever had.莎士比亚是英国所拥有的最伟大的诗人.Is this the best that you can do?你最多只能做到这样吗?[2] 当先行词为代词all,anything,everything,little,much,nobody,nothing时.如：Anyone that wants to succeed must work hard. 任何想要获得成功的人必须努力工作.[3] 当先行词中有含有any,every,no,only,the first,the last,the same时.如：You are the only person that can help me.你是唯一能帮助我的人.Take the first chance that offers.抓住出现的第一个机会.3 没有先行词的关系代词如果关系代词引导的从句不是作定语修饰先行词而是充当句子成分,这种关系代词就没有先行词,它只起连接作用.这种关系代词有：what,whatever,whoever,whichever,wherever等.如：What woke me up was a splashing noise.把我吵醒的是一阵溅水的声音.what从句作主语I don't know what good they could have done.我不知道他们能起什么好作用.what从句作宾语Whoever breaks the law is punished in the end.违法者终将被惩罚.whoever引导的从句作主语感谢您的阅读，祝您生活愉快。
