三大从句从句可分为定语从句、状语从句和名词性从句，它们是中学阶段的重要语法项目，其引导词的选择既是高考必考点，又是同学们学习与复习的一大难点。
定语从句是形容词性从句，相当于形容词的用法，其功能是修饰先行词，对其性质、特征进行描述，先行词在定语从句中一般充当主语、宾语、表语、定语或状语等。状语从句是副词性从句，相当于副词的用法，其功能是在复合句中作状语。根据状语从句的含义，状语从句一般可以充当时间、地点、原因、条件、目的、结果、让步、方式和比较等从句。名词性从句的功能相当于名词词
1．(2013·江苏高考)The president of the World Bank says he has a passion for China, ________ he
remembers starting as early as his childhood.
A ．where
B ．which
C ．what
D ．when
解析：选B 考查定语从句。分析句子结构可知，“________ he remembers starting as early as his childhood”为定语从句，先行词是passion ，且空处在从句中作宾语，因此选which 。
2．(2013·安徽高考)Mo Yan was awarded the Nobel Prize for Literature in 2012, ________ made one of the Chinese people's long-held dreams come true.
A ．it
B ．that
C ．what
D ．which
解析：选D 考查定语从句。句意：莫言获得了2012年诺贝尔文学奖，这使得中国人民很久以来的一个梦想得以实现。此处为非限制性定语从句，修饰整个主句。it 和what 不能引导定语从句，可排除；that 不能用于引导非限制性定语从句。
which 既可引导限制性定语从句也可引导非限制性定语从句，在从句中作主语、宾语或表语，
高考中的考查重点是which 在非限制性定语从句中的应用。which 引导非限制性定语从句时，常代指整个主句。
We hope the measures to control house prices, which are taken by the government, will succeed. 1．(2013·新课标全国卷Ⅱ)When I arrived, Bryan took me to see the house ________ I would be
staying.
A ．what

C ．where
D ．which

A．what B．which C．where D．how
解析：选C考查定语从句。句意：他写了一封信，在信中他解释了在那起事故中发生了什么。分析句子成分可知，空处引导定语从句，a letter是先行词，且关系词在从句中作地点状语，故用where引导。where在这里相当于in which。

A．which B．that C．when D．where
解析：选D考查定语从句的关系词。分析句子结构可知，此处为定语从句。position是先行词，定语从句中缺少地点状语，故用关系副词where。

(1)表示具体的地点
Stephen Hawking believes that the earth is unlikely to be the only planet where life has developed gradually.(2010·福建高考)
史蒂芬·霍金认为，地球可能不是唯一有生命进化的行星。
(2)表示模糊的地点和抽象意义的地点(常见的先行词有race, job, activity, case, situation, point, position, stage, degree等)，但这些词在从句中作主语或宾语时用that/which。
They have reached the point where they have to separate with each other.(作状语)
他们已经到了必须分手的地步。
Remember that there is still one point which we must make clear at the conference tomorrow.(作宾语)

2．(2012·安徽高考)The limits of a person's intelligence, generally speaking, are fixed at birth, but________ he reaches these limits will depend on his environment.
A．where B．whether C．that D．why
解析：选B考查主语从句的引导词。句意：一个人的智力极限，通常来说，出生时就已经定型了，但他是否能够达到这些极限则取决于他的生活环境。根据“depend on”可知，主语从句“ ________ he reaches these limits”中含有不确定因素，故用whether，选B。
whether为连词，在从句中不作任何成分，意为“是否”。

1．(2013·江苏高考)In the global economy, a new drug for cancer, ________ it is discovered, will create many economic possibilities around the world.

初中英语语法——三大从句汇总 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）。以 下是一些基本的从句的语法知识点 A、定语从句专项讲解与训练 一、定语从句概念 定语从句（attributive clause），顾名思义，就是一个句子作定语从属于主句。定语一般是由形容词充当，所以定语从句又称作形容词从句。另外，定语从句是由关系代词或关系副词引导的，故又称作关系从句。 定语从句一般放在它所修饰的名词或代词之后，这种名词或代词被称作先行词。请看示例： The woman who lives next door is a teacher. 先行词定语从句 在所有的从句中，算定语从句最难掌握，因为汉语里没有定语从句，汉语里只有定语，而且总是放在名词之前来修饰名词。 二、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： 先行词主格宾格所有格 人 who whom whose 物 which which whose of which 人、物 that that — （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。例如： An architect is a person who designs buildings. 建筑师是设计房屋的人。
I will never forget the teacher who taught us chemistry in the first year of my senior middle school.我将永远不会忘记在高一时教我们化学的那位老师。 Anyone who wants to apply for this job must send us the resume by email first. 想应聘这个职位的任何人都必须先通过电子邮件向我们发送简历。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。例如：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？ This is the student whom my father taught ten years ago.这是我爸爸十年前教的学生。 The girl who I saw is called Mary. 我见到的那个女孩名叫玛丽。（在非正式英语中，主格who代替了宾格whom，亦可省略） 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。例如：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。例如： 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） Tom works for a factory which makes watches. 汤姆在一个制表厂工作。（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。例如： Is she the girl that sells newspapers? 她是卖报纸的那个女孩吗？（that可以换成who） Where is the ice-cream that was in the fridge?
中考从句讲与练 定语从句： （一）基础：引导词---who, which, that, whom, 练习1.I like cities___________are quiet and clean. 2.I prefer students _________are hard- working. 3.I hate TV shows _________ are noisy and boring. 4.The music __________ is gentle and quiet attracts me a lot. 5.The food __________tastes delicious is not always healthy. 6.Those boys ___________ are playing basketballs over there are from Class Fifteen. 7.The books ____________ are written by Lu Xun are worth reading. 8.The town ___we visited last week is much larger than before.9.The book ___ he bought is very interesting. （二）特例：只用that的情况 1先行词被___________或___________所修饰，或本身是______________________时，只能用 that， 2.被修饰的先行词为 ________________________________________________等不定代词时, 只能用 that. 3.先行词被 _____________________________________________等词修饰时，只能用 that，而不用 which。 4.先行词里同时含有______________________，如I can remember well the persons and some pictures that I saw in the room. 5. 以______________________引导的特殊疑问句，只能用that.如： Who is the girl that is crying? 练习1. I am interested in everything___ is about the 2006 World Cup. 2. Is there anything___I can do for you? 3. This is the very bike ______I lost 4.To my surprise, he gave me nothing __ I need. 5.This is the best dictionary __ I have ever used. 6. He was the first person _______passed the exam. 7.He talked happily about the men and books________interested him greatly. （三）whose 1. The student ______father works in the factory is sitting there. 2. I like the rooms ______windows face south. 3. This is the desk ______legs were broken. 4The woman ___ umbrella you took is angry about it.5.Here comes a girl ___ handwriting is the best . 6The banana __skin is green can’t be eaten.7That tall tree _ leaves are yellow is very old. （四）从句谓语单复数由先行词确定，时态由从句时间状语决定，不必跟主句保持一致。 1-He is one of the boys who ____ (doesn’t, don’t) finish doing homework. 2-I like films which ____(be) exciting and interesting. 3-Children who often ____(eat) junk food are easy to become fat and unhealthy. 4-That boy who _____(run) fastest is from our class. 5Those boys who ____ playing the guitar are from our school. (be) 6The trees which _____ (be) watered yesterday belong to them. 7The man who ____ over there is our teacher.(stand) 8Those boys who ____ playing the guitar are from our school. (be) 9Mr. Brown is one of the foreign experts _______ _________ (work) in China. 10I’m one of the boys ______ ________(like) English best. (五)“介词＋关系代词”注意：介词的选用要考虑： A.与先行词的搭配关系 1）I will never forget the day __________ I joined the army. 2) I will never forget the days ______ I worked here. 3) I will never forget the year ____________ my son went to college. B. 与谓语动词的搭配习惯 1）Have you found the book ________I paid 29 dollars? 2）Have you found the book ________I spent 29 dollars? 3)Have you found the book _____________we learnt a lot? 4) Have you found the book _______she often talks? 关系副词的用法 练习：1. It must be a good place ________________we can do a lot of exercise.
宾语从句： 在句子中起宾语作用的从句叫做宾语从句。通俗的说就是一个句子做另一个句子的宾语. 主要跟在及物动词和介词之后。一般由“引导词＋主语＋谓语＋其它”构成，其语序是陈述句语序。 如何判断： 1．可以从整个句式看,宾语从句只能放在主句谓语动词之后。 2．从引导词看。if充当宾语从句的连接词时，相当于whether，词义为“是否”，when充当宾语从句的连接词时，意为“什么时候”。 3．从时态看。if和when作连接词时，引导宾语从句要注意：从句的谓语动词的时态应根据主句的时态作相应的变化。 所以宾语从句的三大要素：时态语序引导词 前世今生： I know you . you are right.→I know you are right. /I know that you are right. ?引导词 ?that (后面是陈述句) I believe that you are an honest boy. ?what which who I don’t know what they are going to d o. what are they going to do？ whose whom Tell me whose PSP it is.（whose PSP is it？）where when Can you tell me where he lives? where does he live? Why how I know why he was late. (why was he late？) （特殊疑问句） ?if / whether（一般疑问句/是否）I want to know if Miss Gao is back.
从句 从句按其在主句中的句法功能可分为三类: 即名词性从句、形容词性从句(即定语从句)和副词性从句(即状语从句)。 引导从句的词称作关联句. 一、名词性从句 引导这些名词性从句的关联词包括: 从属连词that, if, whether; 连接代词 who,whoever,whom,whomever,which,whichever,what,whatever,wh ose; 连接副词where, when, why, how。 其中, 从属连词只起连接作用, 在从句中不充当任何句法成分, 而连接代词和连接副词既起连接作用, 在从句中又充当一定的成分. That Owen should have married his cousin is not at all surprising. The fact is that he didn't go to the dinner party. I don't know if he will attend the meeting. Have you heard the news that Mary is going to marry Tom? 你听说玛丽要和汤姆结婚的消息了吗?(that引导同位语从句) [提示]
1. 在含有主语从句的复合句中, 为保持句子平衡, 常用it作形式主语,而将真正的主语从句置于句末. It's well-known that water is indispensable to life.(形式主语) 2. 为保持句子平衡, that引导的宾语从句也常用it代替, 而将真正的宾语从句置于主句句末。这常常出现在主句有形容词或分词作宾语补足语的情况下。 He made it quite clear that he preferred to live here. 3. 从属连词whether和if都作“是否…”解, 但if不可引导主语从句和表语 从句。whether可与or(not)连用, 而if不可以。 I don't know whether (if) she is at home. Whether she comes or not makes no difference. 4. that和what引导名词性从句的区别: that在从句中不充当成分,而what在从句中充当一定的成分, 如主语、表语、宾语等。that可省略, what则不可省。 He always means what he says. She suggested (that) he do it at once. 5. 同位语从句大多由从属连词that引导, 常跟在下列名词后面, 如fact, idea, opinion, news, hope, belief等, that不可省。同位语从句一般用来解释说明这些名词的具体含义和内容。 We are familiar with the idea that all matter consists of atoms. The news that we are invited to the conference is very encouraging.
复合句 【语法要点】 复合句是由一个主句加一个或几个从句所构成的句子。从句只用作句子的一个成分，不能独立。根据从句在句子中的作用，可分为名词性从句、定语从句和状语从句三类。 （一）名词性从句 名词性从句包括主语从句、表语从句、宾语从句、同位语从句。其关联词有连接词that、if、whether；疑问代词who、what、which和疑问副词when、where、how、why等。 1.名词性从句句法结构： 从 属 连 词that whether 主 语 从 句 That he will come is certain.（that不可省） Whether she is coming or not doesn’t matter too much. （不能用if） 宾 语 从 句 I think（that）he will be all right in a few days. I went in and asked if（=whether）they had a cheap suit. I wonder whether（不能用if）it is true or not. 表 语 从 句 The fact is（that）I have never been there. The question is whether（不能用if）it is worth doing. 同 位 语 从 句 The fact that she had not said anything surprised all of us. They asked me the question whether the work was worth doing. 连接代词 that who whom whose which 主 语 从 句 Who will help him is not known. What he said is very important. Which side will win is not clear. 宾 语 从 句 （1）作及物动词的宾语。例如： I really don’t know what he is doing. Do you know who/whom they are waiting for? He asked whose dictionary it was. He can’t tell which method they will use for the experiment. （2）作介词的宾语。例如： Pay attention to what the teacher said. I wondered to whom he had given the letter. 表 语 从 句 That is what he is worried about. The question is who will come here. The question is which team will win the match.

一. 宾语从句object clause： 一. 定义definition： 在句子中起宾语作用的从句叫做宾语从句。 二. 连接词connections： that: I think that you can pass the exam. Whether/if: I don’t know what the word means. “Wh”: I don’t know what the word means. I don’t know where he found the book. 只用whether的情况： 1. 与or not连用： I don’t know whether it’s raining or not. 2. 与动词不定式连用： He doesn’t know whether to accept the invitation. 3. 连接词前有介词时： It depends on whether he is coming. 三. 时态tenses: 1. 主句是一般现在时态，从句根据实际情况而定(各种时态均可) She wants to know what he has done for the exam. 2.主句是一般过去时态，从句用相应的过去的时态。 1）She said that she was a student. 2）She said that she would fly to Japan in a week. 3）She said that she had finished her homework already. 3. 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. 二. 定语从句Attributive clause： 1.定义：在复合句中修饰名词、代词的从句叫定语从句 2.先行词指人who /that 先行词指物which/ that 3. 定语从句一般紧跟被修饰的名词或代词（即先行词）后 4.关系代词代替先行词在句子中担当成分，所以从句中不可再出现其他代替先行词的代词 5.翻译方法“…. 的” Eg. 1. Yesterday we bought a book which is really hard to understand. 2. The students who are from Maple Leaf School like learning English. Whom: 先行词指人，则代替先行词在定语从句中充当宾语（包括介词的宾语）, 与who的区别是如果前面带介词则必须用whom 1.This is the teacher whom\who we like best. 2. I don’t like the boy to whom you are talking. Whose : 指人或物，作定语，表示“…的” eg: Harry is the boy whose mother is our math teacher.
定语从句 一、基本概念： 定语： 定语从句： Do you know the man who spoke at the meeting just now That is the house where he lived ten years ago. 引导词：关系词 关系代词有：that, who, whom, whose, which; 在从句中充当： 关系副词有：when, where, why. 在从句充当： 先行词： 定语从句中引关系词的作用： 二、关系词的用法： （一）关系代词的用法： 1． He is the man lives next door. The train has just left is for Shenzhen. 2． The man ________ we have just seen is a famous writer. Where is the book ___________I bought last week （二）关系副词的用法： 1． I still remember the time ________I first became a college student. Do you know the date __________Lincoln was born
(三) 使用关系副词应注意下列几点： 1．这三个关系副词在意义上都相当于一定的介词+which结构： when = on (in, at, during…) + which; where = in (at, on…) + which; why = for which. 如： I was in Beijing on the day when (=on which) he arrived. The office where (=in which) he works is on the third floor. This is the chief reason why (=for which) we did it. 2．当先行词是表时间的time, day等和表地点的place, house等时，一定要注意分析从句的结构，如果缺少主语或宾语时，关系词应该用which或that, 缺少时间状语或地点状语时，才能用when或where，试比较： I’ll never forget the day _________ my hometown was liberated. I’ll never forget the days____________we spent together last summer. His father works in a factory____________radio parts are made. His father works in a factory______________makes radio parts. 三．限制性定语从句与非限制性定语从句 1．限制性定语从句 This is the telegram which he refers to. Is there anything (that) I can do for you 2．非限制性定语从句 This note was left by Tom, who was here a moment ago. As a boy, he was always making things, most of which were electric.

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）。 以下是一些基本的从句的语法知识点 A、定语从句专项讲解与训练 一、定语从句概念 定语从句（attributive clause），顾名思义，就是一个句子作定语从属于主句。定语一般是由形容词充当，所以定语从句又称作形容词从句。另外，定语从句是由关系代词或关系副词引导的，故又称作关系从句。 定语从句一般放在它所修饰的名词或代词之后，这种名词或代词被称作先行词。请看示例： The woman who lives next door is a teacher. 先行词定语从句 在所有的从句中，算定语从句最难掌握，因为汉语里没有定语从句，汉语里只有定语，而且总是放在名词之前来修饰名词。 二、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： 格 先行词主格宾格所有格 人who whom whose 物which which whose of which 人、物that that — （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。例如： An architect is a person who designs buildings. 建筑师是设计房屋的人。 I will never forget the teacher who taught us chemistry in the first year of my senior middle school. 我将永远不会忘记在高一时教我们化学的那位老师。 Anyone who wants to apply for this job must send us the resume by email first. 想应聘这个职位的任何人都必须先通过电子邮件向我们发送简历。 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。例如： 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？ This is the student whom my father taught ten years ago. 这是我爸爸十年前教的学生。 The girl who I saw is called Mary. 我见到的那个女孩名叫玛丽。（在非正式英语中，主格who代替了宾格whom，亦可省略） 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。例如： 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

初中三大从句 一、中考要求： 宾语从句、定语从句、状语从句的用法是中考热点之一，主要考查三种从句的引导词的选择；宾语从句的语序和时态；状语从句主要考查时间状语从句、条件状语从句、因果状语从句，特别是条件状语从句的时态、so… that引导的结果状语从句和目的状语从句等。 二、知识要点： 1. 宾语从句： 在句子中起宾语作用的从句叫宾语从句，中考主要考查的知识点有三个：引导词、语序和时态。 宾语从句的引导词有三种：1）that；2）whether/ if；3）特殊疑问词What/ when/ where/ who等。例如： He said that he could help me. 他说他能够帮助我。 Your mother asked if you could finish your work this week. 你妈妈问这个星期你能否完成工作。 Can you tell me when the sports meeting will begin？ 你能告诉我运动会将在什么时候开始吗？ 1) 以that引导的宾语从句： that引导的宾语从句一般都是由陈述句充当，引导词that没有实际意义，不在从句中作任何成分， that可以省略，而且从句成分齐全，句意完整。 Do you think (that) it will rain? 你认为天会下雨吗？ He said (that) he could come on time. 他说他会准时来的。 2) 以whether或if引导的宾语从句： 从属连词if, whether引导的名词从句是由一般疑问句或选择疑问转化而来的，变成从句后，语序由 原来的倒装语序变成陈述语序。whether和if意思是“是否”。 Let us know whether / if you can finish the work before Friday. 请让我们知道你是否能在星期五以前把工作做完。 I don’t care whether you like the story or not. 我不在乎你是否喜欢这个故事。 注意： 以下情况一般只用whether不用if。 ①接带to的动词不定式。
初中英语三大从句汇总讲解 从句是相对于主句而言的，即它是从属于某一个主句，而不能单独作一个句子。在英语中主要有三大从句，即： 1. 名词性从句 2. 定语从句 3. 状语从句。 1）主语从句用作主语，如： That the earth is round is true. 地球是圆的是真实的。 2）宾语从句用作宾语。如： Do you know where he lives? 3）表语从句用作表语，如： My opinion is that you should not go alone. 我的意见是你不应单独前往。 4）同位语从句用于解释说明前面的名词。如： The fact that the earth is round is true. 地球是圆的的事实是真实的。 5）定语从句相当于一个形容词，用于修饰前面的名词。如： The student who answered the question was John. 回答问题的学生是John. 6）状语从句相当于一个副词，如：
When it rains, I usually go to school by bus. 天下雨时，我通常坐公共汽车上学。 If he comes tomorrow, you will see him. 如果他明天来，你就可以看见他。。要注意在状语从句中有一个规则是“主将从现”，即主句是将来时，则从句要用一般现在时表示将来。 He returned home to learn his daughter had just been engaged.他回家后得知女儿刚刚订婚了。，find，see，hear，to be told，make等具有界限含义的动词。） You must speak louder so that /in order that you can be heard by all. 你必须大声说话，才能让所有人听到你说话。 Since /As the weather is so bad，we have to delay our journey. 天气那么糟，旅行推迟了。，seeing that ，now that ，considering that 等引导。） Though/Though he was worn out，he kept on working. 虽然他已经精疲力竭了，但仍然继续工作。 Where I live there are plenty of trees. 我住的地方树很多。 As water is to fish, so air is to man. 我们离不开空气，犹如鱼儿离不开水。as…so…，as if，as though引导。）主句和从句的划分方法是相同的。句子的成分从谓语动词处来划分比较容易。谓语动词前面的部分是主语，后面常接宾语，修饰谓语动词的是状语，修饰主语、宾语的是定语，若谓语是系动词，则系动词后的部分是表语。如：
