在句子中起名词作用的句子叫名词性从句(Noun Clause s。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。
一.主语从句
主语从句是在复合句中充当主语的从句,通常放在主句谓语动词之前或由形式主语it代替,而本身放在句子末尾。
1.It作形式主语和it引导强调句的比较
It作形式主语代替主语从句,主要是为了平衡句子结构,主语从句的连接词没有变化。而it引导的强调句则是对句子某一部分进行强调,无论强调的是什么成分,都可用连词that。被强调部分指人时也可用who/whom。例如:
a It is a pity that you didn’t go to see the film.你不去看那场电影真可惜。
b It doesn’t interest me whether you succeed or not.我对你成功与否不感兴趣。
c It is in the morning that the murder took place.谋杀案是在早上发生的。(强调句型
d It is John that brok
e the window.是John打碎的窗户。(强调句型
2.用it作形式主语的结构
(1 It is+名词+从句
It is a fact that…事实是…
It is an honor that…非常荣幸
It is common knowledge that…是常识
(2 It is+形容词+从句
It is natural that…很自然…
It is strange that…奇怪的是…

It is said that…据说…
3.主语从句不可位于句首的五种情况:
(1if引导的主语从句不可居于复合句句首。
(2It is said/reported…结构中的主语从句不可提前。例如:
正确表达:It is said that President Jiang will visit our school next week.
错误表达:That President Jiang will visit our school ne xt week is said.
(3It happens/occurs…结构中的主语从句不可提前。例如: 正确表达:It occurred to him that he failed in the exa mination.
错误表达:That he failed in the examination occurred t o him.
(4It doesn’t matter how/whether…结构中的主语从句不可提前。例如:
正确表达:It doesn’t matter whether he is wrong or no t.
错误表达:Whether he is wrong or not doesn’t matter.
(5含主语从句的复合句是疑问句时,主语从句不可提前。例如:
正确表达:Is it likely that it will rain in the evening?
错误表达:Is that will rain in the evening likely?
4.what与that在引导主语从句时的区别
what引导主语从句时在句时在从句中充当句子成分,如主语.宾语.表语,而that则不然。例如:
a What you said yesterday is right.
b That she is still alive is a consolation
二.宾语从句
宾语从句就是在复合句中作宾语的名词性从句,通常放在主句谓语动词(及物动词或介词之后。
1.作动词的宾语
(1由that引导的宾语从句(that通常可以省略,例如:
I heard that be joined the army.我听说他参军了。
(2由what,whether(if引导的宾语从句,例如:
a She did not know what had happened.她不知道发生了什么。
b I wonder whether you can change this note for me.我想知道你是否能帮我改一下笔记。
(3动词+间接宾语+宾语从句。例如:
She told me that she would accept my invitation.她对我说她会接受我的邀请。2.作介词的宾语,例如:
Our success depends upon how well we can cooperate with one another.我们的成功取决于我们之间的合作。
3.作形容词的宾语,例如:
I am afraid(that I’ve made a mistake.我恐怕我已经犯了一个错误。
注意:that引导的从句常跟在下列形容词后作宾语:anxiou s,aware,certain,confident,convinced,determined,glad,proud,surp rised,worried,sorry,thankful,ashamed,disappointed,annoyed,plea sed,hurt,satisfied,content等。也可以将此类词后的that从句的看作原因状语从句。
4.it可以作为形式宾语
it不仅可以作为形式主语,还可以作为形式宾语而真正的宾语that从句则放在句尾,特别是在带复合宾语的句子中。例如:
We heard it that she would get married next month.我听说她下个朋就会结婚了。
5.后边不能直接跟that从句的动词
这类动词有allow,refuse,let,like,cause,force,admire,conde mn,celebrate,dislike,love,help,take,forgive等。这类词后可以用不定式或动名词作宾语,但不可以用that引导的宾语从句。如: 正确表达:I admire their winning the match.
错误表达:I admire that they won the match.
6.不可用that从句作直接宾语的动词
有些动词不可用于“动词+间接宾语+that从句“结构中,常见的有envy,order,
accuse,refuse,impress,forgive,blame,denounce,advise,congr atulate等。例如:
正确表达:He impressed the manager as an honest ma n.
错误表达:He impressed the manager that he was an h onest man.
7.否定的转移
若主句谓语动词为think,consider,suppose,believe,expect,f ancy,guess,imagine等,其后的宾语从句若含有否定意义,一般要把否定词转移到主句谓语上,从句谓语用肯定式。例如:
I don’t think this dress fits you well.我认为这件衣服不适合你穿。
三.表语从句
表语从句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+连系动词+表语从句”。可以接表语从句的连系动词有be,look,remain,seem等。引导表语从句的th at常可省略。另外,常用的还有t he reason is that…和It is b ecause等结构。例如:
1 The question is whether we can make good preparat ion in such a short time.
2 This is why we can’t get the support of the people.
3 But the fact remains that we are behind the other cl asses.
4 The reason he is late for school is that he missed t he early bus.
四.同位语从句
同位语从句就是在复合句中作名词的同位语的名词性从句。
1.同位语从句的功能

1 The king’s decision that the prisoner would be set f ree surprised all the people.
2 The order that all the soldiers should stay still is gi ven by the general.
2.同位语在句子中的位置
同位语从句有时可以不紧跟在它所说明的名词后面,而是被别的词隔开。例如:
He got the news from Mary that the sports meeting w as put off.
3.同位语从句与定语从句的区别
(1定语从句中的that既代替先行词,同时以在从句中作某个成分(主语或宾语,而同位语从句中的that是连词,只起连接主句与从句的作用,不充当句中任何成分。
(2定语从句是形容词性的,其功能是修饰先行词,对先行词加以限定,描述定的性质或特征;同位语从句是名词性的,其功能是对名词进行补充说明。例如:
1 The news that he told me is that Tom would go ab road next year.(他告诉我的消息是汤姆明年将出国。(第一个that引导的从句是定语从句,that在从句中作宾语
2The news that Tom would go abroad is told by him. (汤姆将出国的消息是他讲的。(同位语从句,that在句中不作任何成分

名词性从句精讲(讲解+练习)
名词性从句精讲 在句子中起名词作用的句子叫名词从句(Noun Clauses）。名词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、同位语等，因此根据它在句中不同的语法功能，名词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。That he will come h ere surprises me. I know that he will come here. The news is that he will come here.The new that he will come here surprises me. 一、名词性从句的相同点：1.结构 2.连接词 引导名词性从句的连接词可分为三类： 从属连接：that, whether, if（不充当从句的任何成分） 连接代词：what, whatever, who, whoever, whom, whose, which. 连接副词：when, where, how, why 二、四大名词性从句的剖析 1.主语从句 作句子主语的从句叫主语从句。主语从句通常由从属连词that，whether，if和连接代词what，who，which，whatever，whoever以及连接副词how，when，where，why等词引导。that 在句中无词义，只起连接作用；连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用，在从句中充当从句的成分。例如： That he suddenly fell ill last week made us surprised. 上星期他突然生病了让我们很惊讶。 Whether he will be able to come remains a question.他是否能够来仍然是一个问题。What he wants to tell us is not clear. 他要跟我们说什么，还不清楚。Where the English evening will be held has not yet been announced.英语晚会将在哪里举行，还没有宣布。 有时为避免句子头重脚轻，常用形式主语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。常用句型如下： （1）It + be +形容词+主语从句It is very interesting that he likes such kind of books. （2）It + be +名词+主语从句It is a pity that he missed the lecture. （3）It + be +动词的过去分词+ that从句It is said that they have won the game. （4）It +不及物动词+ that从句It seems that something is wrong with the computer. 另注意在主语从句中用来表示必须、理应如此、建议、要求等语气时，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 … It is suggested (requested, proposed, desired, etc.) that… 2.宾语从句 名词性从句用作宾语叫宾语从句，在句中可以作谓语动词或介词的宾语。引导宾语从句的连接词与

高中英语语法定语从句总复习 郴州资兴三中李俊才 定义：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、关系带词引导的定语从句 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 主语Whom which that 宾语Whose (=of whom) Whose (=of which) that 例１：This is the detective who came from London. 例２：The book which I am reading is written by Tomas Hardy. 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 burst into tears.（所有人都迸出眼泪。） (2) 如果先行词被形容词最高级以及first, last, any, only, few, most, no, some, very等词修饰，关系代词常用that,不用which, who，或whom。 (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。 There are about seven million people taking part in the election, most of whom、are well educated. (4) 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，代替主句所表示的整体概念或部分 概念。在这种从句中，which可以作主语，也可以作宾语或表语，多数情况下意思是与and this 相似，并可以指人。例如： He succeeded in the competition, which made his parents very happy. (5) that可指人或物，在从句中作表语，（指人作主语时多用who）仅用于限制性定语从句中。
名词性从句讲解与辨析
英语语法：名词性从句语法讲解 时间：2016-10-08作者：来源：精品学习网 笔者在此就名词性从句中的几大易错点进行分析，希望对同学们有所帮助。 [关系代词和关系副词的误用] 例1 （2016·全国卷Ⅰ） My uncle is the owner of a restaurant close to that I live. 解析 that→where。本题考查宾语从句，引导词在从句中充当地点状语，所以将that改为where。 例2 （2015·全国卷Ⅱ） As natural architects， the Pueblo Indians figured out exactly thick the adobe walls needed to be to make the cycle work on most days. 解析 how。根据语境和空后的形容词thick可知应用how引导宾语从句，此处表示要弄清楚到底土坯房的墙需要“多”厚。故答案为how。 点拨若从句缺少主语、宾语、表语或定语，则考虑用关系代词；若从句缺少时间、地点、原因、方式等状语成分，则使用关系副词 （when/where/why/how）。 [if和whether的误用] 例3 He asked her the question if they can be friends. 解析 if→whether。question后为同位语从句，只能用whether来引导，故而将if改为whether。 例4 It doesn’t matter so much you will come or not. 解析考查主语从句。句意：你来还是不来，这不怎么重要。代词it作形式主语，真正的主语是whether引导的主语从句。 点拨在表达“是否”这一意思时，我们经常会用到whether和if，但以下几种情况只用whether不用if： 1. 在表语从句、主语从句、同位语从句中； 2. 在介词后的宾语从句中。如：It all depends on whether they will
高中英语【语法归纳】宾语从句
宾语从句 1、定义 如果一个句子在复合句中充当一个宾语，那么这个句子就是宾语从句。 2、与简单句的区分 例：*I love teaching.---简单句 *I love what he is doing.---宾语从句 ★宾语从句在句中作及物动词或介词的宾语。 例：*We can learn what we did not know. *I don't agree with what you said at the meeting. 3、语序 宾语从句的语序一般都为陈述句语序。 A.一般情况下，即使是有疑问词，从句仍然是陈述句式。 例：This book will show you what the best CEOs know. 这本书会告诉你最棒的总经理知道什么。 Can you figure out what the poet really means in this poem. 你能理解诗人在这首诗里真正想表达的是什么吗？ B.但个别宾语从句本应用陈述语序，可由于习惯而保持原疑问语序不变。例：I don't know what is the matter with him. I have no idea what was the matter with him. 我不知到他到底怎么了。 关于matter的从句都是疑问语序基本上说I don't know what is wrong也是
对的，可一般来说都是分成两句讲。 I don't know.Is anything wrong？/what's wrong with you. C.特殊类型的宾语从句：当主句中的谓语动词表示认为、建议、猜测时，如think,say,guess,suppose,suggest,say,believe,feel,consider等，这时宾语从句的引导词是who,which,what,when,where,how,why,就不能按照正常语序安排,经常会将这类词放在句首。 例：What course do you say I should take up this semester? Who do you think the public might choose as their favorite singer this year? 4、连接词（引导词） 1）陈述句做宾语（包括肯定句和否定句），连词由that引导。在口语或非正式体中常省略。 例：I don’t know（that）Tom was late again. 2）一般疑问句做宾语，用if／whether引导，if或whether在宾语从句中不作成分。但if和whether在句中的意思是“是否”。 例：I want to know if(whether)he lives there. He asked me whether(if)I could help him. ★if/whether的区别 A.从句放在句首表示强调时，只能用whether； B.及物动词discuss后的宾从，只用whether； C.if与whether都可以与or not连用，但后面紧跟着or not时只能用whether； D.介词后的宾从只用whether; E.后接动词不定式时用whether. 3）特殊疑问句做宾语，用特殊疑问词连接（宾语从句缺什么成分就选择相应的特殊疑问词）。

高中英语语法系列：定语从句
高中英语语法系列：定语从句 知识要点 1.关系代词和关系副词的选用 2.限制性定语从句和非限制性定语从句的区别 3.几组的关系词特殊用法 一、定义：在复合句中，修饰名词或代词的从句叫做定语从句。 The happy man who lives next to me sells vegetables. You must do everything that I do. 被定语从句修饰的词，叫先行词。比如上面两句中的man和everything. 引导定语从句的词，叫关系代词和关系副词。比如who,whom,that,which,wh ere,when,why等 关系词三重作用：①连接主从句；②指代先行词；③在定语从句中担任句子成分。 The man who lives next to me sells vegetables. 该句中，who lives next to me是定语从句，修饰先行词the man，“who”是引导定语从句的关系词，代替先行词the man，在定语从句中作主语。 二、关系词 引导定语从句的关系代词有who,whom,which,that,whose,as等和关系副词w here,when,why等。关系代词和关系副词在定语从句中担任句子成分。
1.用关系代词that,which,who,whom引导的定语从句 who指人，用作主语 whom指人，用作宾语 which指物，用作主语、宾语皆可 that指人和物，用作主语、宾语皆可 The teacher who visits our school today is from Guangzhou. Mrs Read is the person whom you should write to. They planted some trees which didn’t need much water. The fish(which)we bought this morning were not fresh. A plane is a machine that can fly. The noodles(that)I cooked were delicious. 2.用关系代词whose引导的定语从句： 先行词既可指人，也可指物，一般译为“谁的”“什么东西的”，请看例子 The room whose window faces south is mine. 3.用关系副词when、where、why引导的定语从句 (1)when在从句中作时间状语 October lst,1949is the day when(=on which)the People’s Republic of Chin a was founded. (2)where在从句中作地点状语 I recently went to the town where(=in which)I was born. (3)why在从句中作原因状语 The reason why(=for which)he was late was that he missed the train.

That; what B. That; that C. What; that D. What; what 【答案】 A 【解析】【分析】句意：众说周知，礼貌在每一个国家中都是非常重要的，但是麻烦是，不同的国家对于什么是良好的礼貌有着不同的认识。逗号前有两个谓语动词，一个是are，一个是is known，故是两句话，需填连词连接这两句话，根据句意可知，前面是主语从句，故填that，此处的that，只起连接作用不作任何成分。about是介词，其后是个句子故应填连词把这两句话连接起来，所缺词作are的表语，故填what。因此选A。 【点评】考查名词性从句，本题涉及that引导的主语从句和what引导的宾语从句。 2．Some people believe _______ has happened before or is happening now will repeat itself in the future. A. whatever B. whenever C. wherever D. no matter what 【答案】 A 【解析】【分析】句意：一些人认为之前发生的或现在正在发生的任何事情在将来都会重复发生。Whatever has happened before or is happening now是一个主语从句，whatever既引导起这个主语从句，也在句中做主语。BC项都属于副词的性质，都不能做主语，通常只能做状语；no matter what只能用来引导状语从句，故选A。 【点评】考查名词性从句，本题涉及"特殊疑问词+ever"引导的主语从句。 3． is even more important is the earth cooled down, water began to appear on its surface. A. When; that; when B. What; whether; as C.

A. when are the planes to take off B. that are the planes to take off C. where are the planes to take off D. when the planes are to take off 【答案】 D 【解析】【分析】句意: 飞机什么时候起飞已经宣布了吗？此处是when引导的主语从句，且要用陈述句语序，故选D。

(表语从句) 我的希望是她能很快康复。 2) Everybody hopes that she will soon be well again.（宾语从句） 大家都希望她能很快康复。 3) That she will soon be well again is our hope.（主语从句） 她能很快康复是我们的希望。 b. whether, if（均表示“是否”表明从句内容的不确定性，不作成分） 1) Whether he is coming or not doesn’t matter too much.(主语从句，不能用if) 2) I went in and asked if/whether they had a cheap suit. 3) I wonder whether/if he will come in such bad weather. c. 连接代词：what, whatever, which, whichever, (在从句中作主语，宾语，表语，指物) 1) ____he need is more time. 显然，主语从句：he是主语，谓语动词need缺宾语，因此应填what. 2) Tell us ___you saw and heard during your visit to that university. 3) This is not ___I want. 4) ____some people are against is ___other people are for. 5) The question is which team will win. 6) I have two apples, I don’t know which you want. 归纳：what一般用于不知道内容或范围的句子；which“哪一个……”一般用于给出内容或范围的句子。可作主语，宾语，表语，还可作定语。 d. who, whoever, whom, whomever, whose（在从句中作主语，宾语，表语，定语，指人） 1) Who will give us a lecture is unknown. 2) The question is who will come here. e. 连接副词：when, where, how, why, whenever, however, wherever (在从句中作状语) 1) I have no idea how he learned about it. 2) Where she has gone is not known yet. 3) When he will start is not known yet. 4) This is why he is late. 注意：连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用，在从句中充当从句的成分。

名词性从句精讲
名词性从句精讲 来源：普特英语 在复合句中起名词作用的从句叫名词性从句，包括作主语从句、表语从句、宾语从句和同位语从句。 (1)主语从句 就是在复合句中作主语的从句。主语从句常用that, whether, who, whom, whose, what, which, when, where, how, why, whatever, whoever等引导。如： Whether he will be able to come remains a question. 他是否来还是问题。 That China is a great socialist country is well known. 众所周知，中国是一个伟大的社会主义国家。 注：为避免头重脚轻，使句子平衡，常用it作形式主语，而将主语从句后置。如上述第二 例常说成： It is well known that China is a great socialist country. 但是，由连接代词what, whatever, whoever等引导的主语从句一般不能用形式主语。如：What he found surprised me greatly. 他的发现使我非常吃惊。 Whoever is finished may rest. 凡是做完工的人都可以休息。 (2)表语从句 就是在连系动词之后作表语的从句。引导表语从句的连接除与引导主语从句的连接词外，还有as if，as though。如： The question is whether he is able to do it alone. 问题是他能否单独做这件事。 It looks as if (though) it is going to snow. 天好像要下雪似的。 注意：要区分以下句式： 1. that’s why+结果；that’s because+原因。 2. the reason why /for…is that… He is absent. That’s because he is ill. 他缺席，这是因为他生病了。 He is ill. That’s why he is absent. 他病了，这就是他缺席的原因。 The reason why he is absent is that he is ill. 他缺席的原因是他生病了。 (3)宾语从句 就是在复合句中作宾语的从句。引导这宾语从句的连接词与引导主语从句的连接词基本相同。如： They didn’t say which they wanted. 他们没有说他们想要哪一个。 I am sure (that) no harm will ever come to you. 我肯定你永远不会受伤害。 I was surprised at what has happened.我对发生的事感到惊讶。 注意：当think, believe, suppose等的疑问式后面跟连接代词或连接副词引导的宾语从句时， 习惯上将这些连接词置于句首，即“连接代/副词＋do you think /believe /expect＋宾语从句的

高中英语语法专题 名词性从句讲解与练习
一对一个性化学科优化学案 一、概述 在复合句中具有名词的性质的作主语、表语、同位语、宾语的从句叫名词性从句。因此，我们把主语从句、表语从句、同位语从句和宾语从句这四种从句统称为名词性从句。 It is a fact that English is being accepted as an international language. (主语从句) The trouble is that she has lost his address.（表语从句） They have no idea at all where he has gone.（同位语从句） Do you remember how he came?（宾语从句） 二、主语从句(subject clauses) 1、概述 在复合句中起主语作用的从句叫主语从句。引导主语从句的词有从属连词、关系代词、连接副词等。引导主语从句的关联词有从属连词that 、whether ，关系代词：who, what, which , whom, whose, whatever, whoever, whomever, whichever ；关系副词：when, where, how, why, however, whenever, wherever 等。 That you don’t like him is none of my business. What he said is true. Whether the football game will be played depends on the weather. 2、从属连词that ，whether 引导的主语从句。 从属连词that ，whether 在主语从句中的作用只是引导主语从句，它们在从句中不担任成分，不能省略。 Whether she will come or not is still a question. That they will go is certain. Whether she's coming or not doesn't matter too much. 3、it 作形式主语引导主语从句。 如果主语从句太长，为避免句子结构头重脚轻，我们可用it 作形式主语，而把主语从句放在主句谓语部分之后。That 引导的主语从句可用it 代替，that 不可省略。 用作it 作形式主语的结构： （1）It is/was +形容词+that 从句 It ’s natural that … 很自然…… It ’s obvious that … 显而易见…… （2）It is/was +名词+that 从句 It ’s a pity that … 遗憾的是…… It ’s a fact that …事实是…… 鹰击长空—基础不丢
