高考语法：表语从句讲解及练习
一、定义：
1.表语从句就是用一个句子作为表语。说明主语是什么或者怎么样，由名词、形容词或相当于名词或形容词的词或短语充当，和连系动词一起构成谓语。
Eg:The problem is puzzling. 这问题令人困惑
主语连系动词形容词作表语
The problem is when we can get a pay rise. 问题是什么时候我们可以得到加薪.
主语连系动词一个句子作表语---表语从句
2.连接表语从句的连接词有：that, what, who, when, where, which, why, whether,how.
He has become a teacher. 他已经成为一名教师。
He has become what he wanted to be ten years ago.
他已经成为了他10年前想成为的。
She has remained there for an hour.
她曾在那里停留了一个小时。
She has remained where I stood yesterday for an hour.
她一直在我昨天站的地方站了一个小时。
His suggestion is good. 他的建议是好的。
His suggestion is that we should stay calm.
他的建议是，我们应该保持冷静。
The question is when he can arrive at the hotel.
问题是，他什么时候可以到达酒店。
who will travel with me to Beijing tomorrow.
谁与我明天将前往北京。
why he cried yesterday. 昨天他为什么哭。
how I can persuade her to join us in the party.
我怎么能说服她加入我们的派对。
whether the enemy is marching towards us.
是否敌人正向我们行进.
二、注意：
1.表语从句一定要用陈述语序。
False: The question is when can he arrive at the hotel.
Right: The question is when he can arrive at the hotel.
2.不可以用if，而用whether 连接表语从句(as if 例外）。
引导宾语从句时可以互换if/whether 位于介词后要用whether，位于句首时要用whether 引导表语从句，主语从句，同位语从句时要用whether
False: The question is if the enemy is marching towards us.
Right: The question is whether the enemy is marching towards us.
Right: It looked as if he had understood this question.
3.不像宾语从句，在有表语从句的复合句中，主句时态和从句时态可以不一致。
Right: The question is who will travel with me to Beijing tomorrow.
Right: The question is why he cried yesterday.
在表语从句中不可以省掉。
表语从句的基本用法:
表语从句只能置于主句之后，而主句的动词只能是联系动词。
名词性从句在be等系动词后作表语时被称为表语从句.
例如： The problem is how we can get the things we need. (how 在表语从句中充当方式状语)
问题是我们怎样能弄到我们需要的东西。
The scissors are not what I need. (what 在表语从句中充当宾语)
这把剪刀不是我所需要的。
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. (what在表语从句中充当直接宾语)
那就是我想要对你讲的。
That is why she failed to pass the exam. (why 在表语从句中充当原因状语)
那就是她考试不及格的原因。
注意：“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，又如： That is why you see this old woman before you know, Jeanne. (前文提到Jeanne对老妇人显得苍老憔悴深感诧异，说话人对她讲述了其中的原因之后，用这一句来进行概括)。
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，例如：That is (the reason) why I cannot agree. 这就是我不能同意的理由。
(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，例如：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)
例题精析：

A. when
B. why
C. whether
D. that
［答案］ D
［解析］下划线处之后是包含一个原因状语从句的表语从句，如果看不出它是充当整个句子结构的表语从句将难以把握整个句子的意思。因此，应选择可引导名词性从句且不充当任何成分的that。

A. What; because
B. What; that
C. That; what
D. That; because
［答案］ B
［解析］第一个下划线处的引导词引导主语从句并在该主语从句中充当主语，特指令校方骄傲的事情，应选用关系代词型的引导词what；第二个下划线处引导表语从句表示原因、理由，应由that引导对应的名词性从句。
［考题6］—Are you still thinking about yesterday’s game
— Oh, that’s ____. (2003北京春)
A. what makes me feel excited
B. whatever I feel excited about
C. how I feel about it
D. when I feel excited
［答案］ A
［解析］ A选项的意思是“令我感觉激动的事物”； B选项的意思是“我觉得激动的任何事物”； C选项的意思是“我对它感觉的方式”； D选项的意思是“令我感觉激动的时间”。四个选项中A最适合跟代表“game”的主语that 对应，充当表语从句。
表语从句与宾语从句的关系
宾语从句和表语从句都属于名词性从句。其作用跟名词在句中的作用相同。故充当宾语的句子叫宾语从句，充当表语的句子叫表语从句。
宾语从句
(1)对于宾语从句要掌握以下三点
①语序: 从句的语序必须是陈述句语序, 即“主语 + 谓语”这种形式。
②时态: 当主句是一般现在时或一般将来时的时候, 从句可以是任何时态, 而当主句是一般过去时的时候, 从句, 从句时态必须是过去时范围的时态, 即(一般过去时, 过去进行时, 过去完成时, 过去将来时)。
③连接词: 当从句意思完整, 主句意思肯定时, 连接词用that, 且可以省去, 当从句意思完整, 主句意思不确定或含否定含意时, 常用if或whether(是否), 当从句意思不完整时, 连接词则是代替不完整部分的特殊疑问词。
表语从句
在句子中起表语作用的从句叫做表语从句，位于主句系动词的后面。表语从句的引导词和主语从句的引导词相同。也是名词性从句的一种。
如： What the police want to know is when you enred red the room警察想知道的是你什么时候进的房间。
The The trouble is that we are short of funds困难是我们缺乏资金。
This This is what we should do这是我们应当做的。
That”s s why I want you to work there那就是我要你在那儿工作的原因。
His His first question was whether Mr. Smith had arrived yet他的第一个问题是史密斯先生到了没有。注意：从句中的疑问句用正常语序，即陈述语序。
as as if, as though, because也可用来引导表语从句。
She She seems as if she had done a great thing她看起来好像做了一件大事。
It It is because you eat too much那是因为你吃得太多了。
初中英语语法宾语从句讲解_专项练习及答案
初中英语语法宾语从句讲解，专项练习及答案注意！宾语从句小口诀： 宾语从句三注意，时态语序引导词； 主句一般现在时，从句不需受限制； 主句一般过去时，从句须用相应时； 陈述句转化that引，一般疑问句用if/whether, 特殊问句疑问词，引导词后陈述式。 一、基本讲解 1 概念:在句中担当宾语的从句叫宾语从句，宾语从句可作谓语动词的宾语，也可做介词的宾语。eg, He said he was good at drawing. (动词宾语) He asks him how long Mike has been down . (动词宾语) Miss Zhang is angry at what you said. (介词宾语) 2.连接词 (1) .陈述句转化成宾语从句时，引导词用that,口语中常常省略。 e.g, She told me (that) she would like to go with us. (2)以whether 或if 引导的宾语从句, 主要用来引导一般疑问句意思或选择疑问句意思的宾语从句，从句同样是陈述语序 eg, I wonder if /whether u have told the new to Li Lei . 注意：一般情况下，whether 和if 可以互用，但有些情况例外。 a. 当从句做介词的宾于是只用whether 不用if eg, We are talking about whether we'll go on the pinic. b. 引导词与动词不定式或not 连用时，只用whether. eg, Please let me know what to do next. Could you tell me whether u go or not? c. if当如果讲时，引导的是条件状语从句，这时不能用whether. (3).特殊疑问句转化成宾语从句时，引导词用特殊疑问词；引导词后要用陈述句语序。 E.g. Could you tell me what's the matter\wrong with you? 特殊情况：：当do you think后接特殊疑问句转化成宾语从句时，句式结构应为引导词＋do you think＋陈述句语序。 3.宾语从句时态
初中英语语法——三大从句汇总(重点笔记)知识讲解
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?
表语从句讲解及练习
表语从句 1．定义：用作表语的从句叫做表语从句。 2．引导表语从句的关联词的种类： (1)从属连词that。在从句中不做成分。如：The trouble is that I have lost his address.麻烦是 我把他的地址丢了。The reason was that he was late for school. (2)从属连词whether,as,as if。如： (3)looked just as he had looked ten years before.他看起来还与十年前一样。 (4)question is whether they will be able to help us. 问题是他们是否能帮我们。 (5)注：从属连词if一般不用来引导表语从句，但as if却可引导表语从句，如： (6)All this was over twenty years ago, but it’s as if it was only yesterday. (7)这都是20多年前的事了，但宛如昨天一样。 The key is whether we can solve the problem.注：能跟表语从句的谓语动词一般为系动词be, seem, look，sound等。如： (8)He looked just as he had looked ten years before. 他看起来还与十年前一样。 It sounds as if someone is knocking at the door. 连接代词who, whom, whose, what, which, whoever, whatever, whichever 在表语从句中做主语、宾语等。如：The problem is who we can get to replace her. 问题是我们能找到谁去替换她呢。 (9)That was what she did this morning on reaching the attic. 那就是她今晨上了阁楼干的。 The problem is who we can get to replace her. (10)我想问的是谁离开了。My question is who left. 连接副词where, when, how, why。 What I wonder is when he left. 我想知道他是何时离开的。 This is where they once lived. 这就是他们曾经住过的地方。 That is why he didn't come here. The question is how he did it. (11)连词because可引导表语从句。如： (12)I think it is because you are doing too much. 我想这是因为你做得太多。 It's just because he doesn't know her. (13)T hat's because he didn't understand me. 那是因为他没有理解我.(That's because...强调原因) (14)T hat's why he got angry with me.那正是他对我生气的原因。(That's why...强调结果) (15)在一些表示“建议、劝说、命令”的名词后面的表语从句中，谓语动词用虚拟语气。should+动词原形表示，should可省略。如： (16)M y suggestion is that we (should) start early tomorrow. 我的建议是我们明天一早就出发。

初中英语定语从句的用法解析
初中英语定语从句的用法解析 【摘要】定语从句是一种形容词的关系从句。它由关系代词或关系副词引导（1）。初中英语中的定语从句仅限于限制性定于从句，但对初中生来说，定语从句既是一个重点，也是一个难点。 【关键词】定语从句先行词关系代词关系副词 一、英语中的定语从句与汉语中的定语位置不同。 在复合句中，修饰某一名词或代词的从句叫做定语从句。英语中的定语从句始终要放在被修饰的词之后，而汉语中的定语则放在被修饰词之前。如： The man who / that I saw at the school gate yesterday is my English teacher. 先行词定语从句 昨天我在校门口看见的那个人是我的英语老师。 二、英语从句中的句型结构比较复杂，有先行词、关系代词或关系副词。被定语从句修饰的词叫先行词，引导定语从句的关联词有关系代词或关系副词。限制性关系分句和它的先行项的所指意义有着不可分割的联系（2）。关系代词或关系副词放在先行词和定语从句之间起纽带作用，关系代词或关系副词在定语从句中要充当一个成分。关系代词在句中可作主语、宾语或定语，关系副词在句中作状语。如： I am waiting for the boy who /that is wearing a red coat. （主语） 先行词关系代词 我正在等穿着红色外套的那个男孩。 The dictionary that / which my sister gave me last Sunday is very expensive.(宾语) 先行词关系代词 我姐姐上周星期天给我的那本字典很贵。 The woman is his mother whose name is Linda Brown. (定语) 先行词关系代词 那个是他的母亲，名叫琳达·布朗。 That is the house where my father used to live.(状语) 先行词关系副词 那是我父亲曾经居住过的房子。 三、初中英语中的定语从句关系代词或关系副词的具体用法。 1. who指人（也可用that），在定语从句中作主语，也可作宾语。如： Yesterday I helped an old man who / that lost his way. （主语） 昨天我帮助了一位迷路的老人。 Mr Wang is the man (who / that / whom )you met in the zoo this morning.(宾语) 王先生就是今天早上你在动物里遇到的那个人。 注意：关系代词who指人,作宾语时，可用whom代替；作宾语时，关系代词可省略。作其它成分，关系代词则不能省略。 2. whose指人，也可指物。在定语从句中作定语。 The boy whose mother is ill is staying at home to look after her today. 其母亲生病的那个男孩今天呆在家里照顾她。 I have a story book whose cover is red. 我有一本封面是红色的故事书。 3. which指物（也可用that），在定语从句中作主语，也可作宾语。如： Football is a game which / that is liked by most boys. （主语） 足球是被大多数男孩喜欢的运动。 I don’t believe the news which / that Tom won the game. (宾语)
表语从句讲解及专项练习、答案
表语从句讲解及专项练习 概念：表语从句是在复合句中作表语的名词性从句。 放在系动词之后,一般结构是“主语+系动词+表语从句” 可以接表语从句的连系动词有be, look, remain, seem等。 ★ The trouble is that we are short of money.困难是我们资金短缺。 ★ That is why stone walls are used instead of fences around New England fields.这就是为什么在新英格兰用石头墙而不用栅栏的原因。 ★ At that time, it seemed as if I couldn't think of the right word anyhow.当时,我似乎怎么也想不出一个恰当的字眼来。 引导表语从句的词： 从属连词that、whether、as though、as if（That引导表语从句时，在口语中，间或可以省略。） 关系代词who, what, which, whom, whose, whatever, whoever, whomever, whichever等； 关系副词when, where, why, how, however, whenever, wherever等。 ※由从属连词that，whether引导的表语从句。 that在引导表语从句时无词义，而whether有词义，意为、“是否”。这时主句的主语常常是些抽象名词，如question(问题)，trouble(麻烦)，problem(问题)，result(结果)，chance(可能性)，suggestion(建议)，idea(想法)，reason(理由)等。表语从句对主句主语进行说明、解释，使主语的内容具体化。 例如： ★ The trouble is (that) she has lost his money. 麻烦的事是他丢了钱。 ★The question is whether we need more ice cream.问题是我们是否还需要一些冰淇淋。 ★The problem was that it was too valuable for everyday use.问题是它作为日常之用太贵重了。 ★What she couldn’t understand w as that fewer and fewer students showed interest in her lessons. 我们不能理解越来越少的学生对他的课不感兴趣。 ※由关系代词引导的表语从句。 关系代词who, what, which, whom, whose, whatever, whoever, whomever, whichever等引导表语从句，在句中作主语、宾语、表语，关系代词不能省略。 例如： ★The question is which of us should go.问题是我们哪一个应该去。 ★The problem was who could do the work.问题是谁能做这项工作。 ★That's what he is worrying about.那就是他在担心的事。
初中英语从句语法讲解
从句 从句按其在复合句中的作用,分为主语从句、表语从句、宾语从句、定语从句和状语从句等。(参见以下各条） ３、各从句在句子中的位置以及用法: (1) 表语从句:在句子中作连系动词的表语的从句,它位于主句中的系动词之后。 例如：Thaｔ is wｈｙ he did not ｃomｅto scｈooｌ yeｓtｅrday. / It is ｂｅcause y ｏu ａｒｅ so ｃleveｒ. (2) 宾语从句:在句子中作及物动词或介词的宾语。 ①基本形式：(主句＋）连词＋从句主语+从句谓语+... ②关于宾语从句连词的选择: 若从句来源于一个陈述句,那么,连词用thaｔ，在口语中thａｔ可以省略； 若从句来源于一个一般疑问句，连词则用if 或whether; 若从句来源于一个特殊疑问句,则连词就是疑问词(如whａt,who，wｈere,when等）例如：Theｙｂeｌieve that the comｐｕter wiｌl fｉnally ｔake the plaｃe of hｕ man beｉnｇs．(他们相信计算机终将代替人类。) （从句本来就是陈述句)/ I wonder wh ｅther I shoulｄｓay sｏmｅthing ｆor hiｍｔo ｔhe ｈeａｄｍaster． (我不知道是 不是该为他在校长跟前说点什么。) (从句来源于一般问句ＳhalｌＩ say sｏmｅthｉng ｆor him to the headｍaster?)/ Ｈe askeｄ me wheｒe he cｏuｌｄｇeｔ such ｍedicin ｅ. (他问我在哪儿能搞到那样的药。) (从句来源于特殊问句Where caｎｈe get such me ｄｉｃｉne?) ③宾语从句的时态问题：如果主句是现在时,从句则用现在某一时态,甚至可以用过去时; 如主句是过去时，从句则相应地使用过去某一时态，遇到客观真理时仍然用现在时。如:Ｉ t ｈink Ｉ will dｏ better ｉn Eｎglish this ｔerm．（我想本学期我的英语会学得好点。) / Thｅ tｅａcher askｅd the boｙ if ｔhe eａrth ｉｓroｕnd. (老师问那个男孩地球 是不是圆的。) ④下列结构后面的从句一般也作为宾语从句看待： bｅｓoｒrｙ / afraid / sｕrｅ／ｇlａd +that从句,如:I’m sｏrｒy I’m late. (对 不起,我迟到了。)/ Ｉ’m afｒａiｄ hｅ iｓn’t iｎat the ｍｏｍent.(恐 怕他此刻不在家。) (3) 状语从句:在复合句中作状语,其位置可以在主句前或主句后。状语从句可以分为时间、地点、原
初中英语语法宾语从句讲解-专项练习及答案
初中英语语法宾语从句讲解 小口诀： 宾语从句三注意，时态语序引导词；主句一般现在时，从句不需受限制； 主句一般过去时，从句须用相应时；陈述转化that引，一般疑问用if/whether, 特殊问句疑问词，引导词后陈述式。 一．基本讲解来源：直接引语变间接引语 概念:在句中担当宾语的从句叫宾语从句。 Eg: He said,“I am good at drawing”. He said he was good at drawing. (动词宾语) 1.引导词 (1) that引导宾语从句时，通常用陈述句充当, that可省略。 Eg: She said,“I want to go there ”She said (that) she wanted to go there. (2) whether 或if 引导的宾语从句,由一般疑问句/选择疑问句充当，陈述语序。 Eg: “Are you interested in geography?” she said. She asked if/whether I was interested in geography. I wonder if /whether she has told the new to Li Lei . I’m not sure whether he will come or not. 注意：一般情况下，whether 和if 可以互用，但有些情况例外 a. 介词短语后只用whether 不用if eg: We are talking about whether we'll go on the panic. b. 引导词与动词不定式或or not 连用时，只用whether. eg:I can?t say whether or not he will come on time c. if当如果讲时,引导的是条件状语从句，表示‘如果’，不能用whether. Eg: If you want to be a good teacher, it will take times. Whether you can succeed depends on how much effort you pay. (3).特殊疑问词引导宾语从句时，不可省略，陈述句语序。 特殊疑问词为：how , when, where, why ,which whose.

(完整版)初中英语语法专题(状语从句)讲解
初中英语语法专题（状语从句）讲解 状语从句在复合句中作状语，修饰动词、形容词或副词等。状语从句可以表示时间、条件、原因、地点、目的、结果、让步、方式、比较等意义。 知识梳理：提纲挈领，抓住重点和难点！ 各类状语从句连接词（短语）一览表： 时间 when, while, as, as soon as, since, until, after, before 条件 If, unless 原因 As, because, since 地点 Where 目的 So that, in order that 结果So that, so…that, such…that 让步 though, although, even if, however 方式 As 比较 t han, (not)as…as, 时间状语从句： Whenever he comes, he brings a friend. 他每次来都带个朋友。 条件状语从句： As long as I am alive, I will go on studying. 只要我活着，我就要学习。 原因状语从句： Since we live near the sea, we enjoy nice weather.由于我们住在海边，能享受到好的天气。 地点状语从句： Put it where we can all see it.把它放在我们都能看到的位置。 目的状语从句：
Finish this so that you can start another.把这个做完，你可以开始另一个。 结果状语从句： He was so angry that he couldn't say a word. 他气得说不出话了。 让步状语从句： Though he is in poor health, he works hard.虽然他身体不好，但是他工作很努力。 方式状语从句： Students do as the teachers say.学生们按照老师说的去做。 比较状语从句： The work isn't as easy as I thought.这项工作比我想象得难。 例题解析：举一反三，学的更轻松！ 1. 易混引导词while, when, as的区别： when既可以指"时间点",与瞬间动词连用，也可以指"时间段"，与延续性动词连用 （=while）。如： When he came in, his mother was cooking. When (While) we were at school, we went to the library every day. While表示时间段,因此，while 从句的谓语动词要用延续性动词。如： Please don't talk so loud while others are working. As与when用法相似，但着重强调主句动作与从句动作同时发生，有"随着……"或"一边……一边……"之意。如： As you get older, you get more knowledge.随着年龄的增长，你获得的知识就越多。 2．Because,as,since 的区别： Because用于表示直接原因,回答why提出的问题，语气最强；As用于说明原因, 着重点在主句，常译成"由于"；since表示显然的或已知的理由或事实，常译成"既然"。如： Water is very important because we can't live without it. He didn't come yesterday as his mother was ill. I'll do it for you since you are busy.

初中英语语法三大从句汇总重点笔记知识讲解
精品文档 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。 精品文档． 精品文档 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：
