英语三大从句
英语中三大类从句
从句概述
• 从句只能做主句的某一部分,依附于主句 而存在,不能独立。
• 从句也具有句子的特征，即有自己的主 谓结构；而且带有引导词。
• 根据从句在句中的作用，可分为名词性 从句、形容词性（定语）从句和副词性 （状语）从句三类。
一、名词性从句
名词性从句包括主语从句、宾语从句、表语从句和同位语从句。其关 联词有连词that, if, whether；连接代词what, who, which和连接副 词when, where, why, how等。
Ryan was worrying about whether he had hurt her feelings. ⑶ or not紧随其后时；I don’t care whether or not he has a holiday. ⑷ 后接不定式时。 She can’t decide whether to go.
连接词的用法 (三)
３．Who, whom, whose, what, which
连接代词Who, whom, whose, what, which等 在从句中既起连接作用，又担当主语、宾语、表 语等成分，并保留其特殊疑问词词义。如：
No one knows who he was waiting for. Tell me whose house it is. Let me know which train you will be arriving on.
④ It +v. (seems / happened, etc. )+that-clause It seems that Alice is not coming to the party at all. It happened that I was out that day.
初中英语语法——三大从句汇总(重点笔记)
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 firstyear 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。
英语三大从句
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。

英语三大从句
英语三大从句一．名词性从句简介1、主语从句作句子主语的从句叫主语从句。
主语从句通常由连接词that，whether，if; 连接代词what，whatever，who，whoever ，which; 连接副词how，when，where，why等词引导。
例如：What he wants to tell us is not clear. / Who will win the match is still unknown.(1) 主语从句可以位于句首，但有时为避免句子头重脚轻，常用it代替主语从句作形式主语放于句首，而把主语从句置于句末。
主语从句后的谓语动词一般用单数形式。
That the earth is round is true. = It is true that the earth is round.Whether he will come hasn’t been decided. = It hasn’t been decided whether he will come.常用句型如下：①It + be + 名词/形容词+ that从句It is a pity that we can’t go. It is clear that Tom has returned.②It + be + 动词的过去分词+ that从句It is said / reported / believed / known that …③It + 不及物动词+ that 从句另:在主语从句中用来表示惊奇、不相信、惋惜、理应如此等语气时，谓语动词要用虚拟语气“(should) +do”，常用的句型有：It is necessary (important, natural, strange, etc.) that sb. should do sth.It is a pity (a shame, no wonder, etc.) that sb. should do sth.It is suggested (requested, proposed, advised, etc.) that sb. should do sth.(2) 主语从句不可位于句首的五种情况：①It is said /reported that…结构中的主语从句不可提前。
英语三大从句
英语三大从句英语三大从句：宾语从句（在句子中起宾语作用的从句）、定语从句（在复合句中修饰名词、代词的从句）、以及状语从句（在复合句中由从句表示的状语）。
宾语从句一、定义在句子中起宾语作用的从句叫做宾语从句。
二、连接词That: I think that you can pass the exam.Whether/if:I wonder if / whether I can get some advice from you.Ask him whether / if he can come.What: I donrsquo;t know what the word means.Where: I donrsquo;t know where he found the book.只用whether的情况：1. 与or not连用：I donrsquo;t know whether itrsquo;s raining or not.2. 与动词不定式连用：He doesnrsquo;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。
高中英语主要要掌握三大从句
关系代词所代替的先行词是人或物的名词或代词，并在从句中充当主语、宾语、定语等成分。关系代词在定语从句中作主词保持一致。
（1）, who, whom, that
这些词代替指人，“whom”作宾语指人，“that”既可作主语又可作宾语（作宾语可以省略），可以指人也可以指物。
引导名词性从句的连接词可分为三类：
1、连词（5个）：that （宾语从句或表语从句中that有时可以省略） whether,if （均表示“是否”表明从句内容的不确定性）
as if ,as t
2、连接代词（9个）：what, whatever, who, whoever, whom, whomever, whose, which, whichever
高中英语主要要掌握三大从句。
分别是：
1、定语从句（形容词从句）
2、名词词从句（包括主语从句，宾语从句，表语从句，同位语从句）
3、状语从句（副词性从句，包括时间，地点，结果，目的，原因等）
一、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，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。
（3），关系副词where主要用于修饰表示地点的名词，同时它在定语从句中用作地点状语。
3、非限制性定语从句
它起补充说明作用，缺少也不会影响全句的理解。在非限制性定语从句的前面往往有逗号隔开。
二、名词性从句
在句子中起名词作用的句子叫名词性从句 (Noun Clauses）。 名词性从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中不同的语法功能，名词性从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。

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、目得、原因、让步、地点、方式等)。
定语从句一、关系代词引导得定语从句关系代词代替前面得先行词,并且在定语从句中充当句子成分,可以作主语、宾语、定语等。
常见得关系代词有:who, that, which。
它们得主格、宾格与所有格如下表所示:(一)关系代词who, whom与 whose得用法who代替人,就是主格,在定语从句中作主语。
An architect is a person who designs buildings、建筑师就是设计房屋得人。
whom代替人,就是宾格,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得那位先生您认识吗？whose一般代替人,有时亦可代替物,就是所有格,在定语从句作定语。

Do you know the name of the hotel whose window we can see here? 我们这儿能瞧到窗户得那个宾馆叫什么名字,您知道吗？(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,意思就是:the window of the hotel。
)(二)关系代词which得用法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得小说。
(which可以换成that)(三)关系代词that得用法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?她就是卖报纸得那个女孩吗？(that可以换成who)Where is the ice-cream that was in the fridge?放在冰箱得冰激凌哪儿去了？(that可以换成which)Is this the book that you want to buy?这就是您要买得那本书吗？ (that可以换成which,在定语从句作宾语,还可以省略)二、关系副词引导得定语从句常用得关系副词只有三个:when, where, why,在定语从句中充当时间、地点与原因状语。
(一)关系副词when得用法关系副词when代替得先行词表示得就是时间,when在定语从句作时间状语。
In Beijing July and August are the months when it rains very often、北京得七月与八月就是常下雨得月份。
(when先行词就是months)(二)关系副词where得用法关系副词where代替得先行词表示得就是地点,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,我回到了生我养我得家乡。
(where得先行词就是town)(三)关系副词why得用法关系副词why代替得先行词表示得就是原因,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xx给您得原因就是想问问您就是否收到了我得电子邮件。
(why先行词就是reason, 当代英语里why可以用that替代,这时关系代词that就变成了表示原因得关系副词,还可以将why省略)三、特殊关系代词as引导得定语从句(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、您想要拿多少书就拿多少。
(第一个as就是副词,修饰many得;第二个as才就是关系代词,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与 As is known to us均为定语从句,as分别作宾语与主语,替代后面得主句。
) Taiwan is, as you know, an inseparable part of China、您知道,台湾就是中国不可分割得一部分。
(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得区别(一)关系代词who与that得区别1、当关系代词用作主语时,多用主格who。
He who loses hope loses all、失去希望得人就失去一切。
(先行词为代词he, they, any, all, one等时,多用who)I 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who)2、当关系代词用作介词后得宾语时,用宾格whom,不用that。
The man to whom our headmaster talked just now is our English teacher、我们校长刚才与她谈话得那个人就是我们得英语老师。
(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:介词与关系代词不就是紧密相连时,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,上面得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、她就是个从不怕失败得人。
(that用来泛指人)4、当关系代词出现在who开头得疑问句时,应用that。
例如:Who is the girl that is talking to Tom in English?用英语同汤姆交谈得那个女孩就是谁？(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得区别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、她把她所知道得一切都告诉了我。
2、当先行词得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、这就是我读过得最好得一部小说。
He is the only person that has been invited to the ball、她就是惟一应邀参加舞会得人。
3、当关系代词出现在which开头得疑问句时,应用that。
Which was the hotel that was remended to the foreign guest? 哪一个就是推荐给外宾得宾馆？(这里使用that很明显就是为了避免重复which)4、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、北京就是中华人民共与国得首都,将主办2008年奥运会。
5、介词后得关系代词用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％就是德国邮票。
五、定语从句得位置如前所述,定语从句一般总就是直接置于所修饰得名词或代词之后。
有时候,定语从句与先行词之间插入了其她得短语,这样它们被分隔了,这种情况下得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 e tomorrow who will teach you German、明天要来一位新老师教您们德语了。
(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 引导得陈述句性得宾语从句,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,在从句中不做句子得成分,也无词汇意义,在口语中常被省略。
