名词性从句
基本用法
一、定义： 名词性从句相当于名词，可分别作主句的主语、表语、宾语和同位语。因此，名词性从句可分为主语从句、表语从句 、宾语从句和同位语从句。
二、引导词：
1、种类：有连词that / whether / as if，连接代词what / who/ which / whose / whatever / whoever / whomever / whichever，连接副词where / when / why / how / wherever / whenever。
2、功能：名词性从句的引导词一般都有意义且在从句中充当主语、宾语、状语等成分，但that引导名词性从句在从句中只起连接作用，无义且不作成分；whether/if引导名词性从句表“是否”之意，但在从句中不作成分。
3、that引导名词性从句的特殊用法。
1）、that引导主语从句、表语从句、同位语从句时不能省略。如：
①That they are good at English is known to us all.
②The problem is that we don’t have enough money.
③She expressed the hope that they would come to China one day.
2）、that引导宾语从句时可省，但在以下几种情况中不能省略：
①当that从句和主句谓语动词之间有插入词语或者从句主语之间有插入语时，that不可省略；
He judged that, because he was a child, he did not understand wine.
②当that 从句与另一名词性从句并列作宾语时，that不能省；Everyone knew what happened and that she was worried.
③当that作介词宾语时，that不可省掉。但that引导的宾语从句只有在except, in, but, besides等少数介词后偶尔可能用到;
e.g. Your article is all right except that it is too long． The reason lies in that she works harder than the others do.
④that从句作主语和宾语时，可以用it 来替换成以下几种结构表达。**that引导主语从句借助it作形式主语的情况：
It 作主语的常用句型有:
A. It + be +形容词 + that 从句
B. It + be +名称词组(duty/pity..) + that 从句
C. It + be + 过去分词(said/thought..) + that 从句
D. It +不及物动词(seem/happen..) + that 从句
用形式主语 it 的主语从句常见结构
A.It is clear (necessary, important, possible,remarkable that… 很清楚（必要, 重要,可能, 值得注意等)…
B.It is a fact (a good thing, good news…) that … 事实是 ( 好事是,好消息是…)…
C.It is well-known ( reported, recorded, estimated,said, believed) that…众所周知( 据报道,,据记载,据说,据估计)…
D.It turns out ( seems, happens, appears…) that… 结果是 ( 似乎是, 碰巧是, 好象是…)…
E.It has been found (has been proved,can be seen,must be pointed out) that …已发现( 已证明,可以看出,需指出)…
如：
It is a pity that we can’t go swimming.真可惜我们不能去游泳. It happened that I was out that day.碰巧那天我外出了.
It is certain that he will do well in the exam.他考试肯定会考好.
It is said that he told her everything.据说他已告诉了她一切.
***用it 作形式宾语时, 通常将宾语从句移至补语的后面, 即: “主 +谓 + it + 宾语的补语 + 宾语从句” 。
如：She made it a rule that she got early every morning.
She made it clear that it was not her fault.
⑤that和what的区别。
that 引导名词性从句时，在主从句中不以当任何句子成分，也没有任何含义；而what引导名词性从句时，在主从句中都要充当一定的句子成分，what可以分解成定语从句中的先行词 + 关系代词，即常说的先行词 + that。如：
It’s shame that he has made such a mistake.
Do what he says= Do everything that he says.
4、名词性从句与定语从句的区别。
1）、同位语从句与定于从句的区别
A.that引导的同位语从句：
（1）从先行词看
同位语从句与名词之间在逻辑上是“主语+be+表语”的关系。该名词是需要做特殊说明的抽象名词。例如：
They were delighted at the news that their team had won.
The news was that their team had won.
(2)从引导词来看
引导词that在同位语从句中是连词，只起连接作用，无具体词意，that不可省略；that在定语从句中是关系代词，它在从句中充当一定成分——主语或宾语，有具体词意，作宾语时还可以省略。
The factory (that) we visited yesterday is a chemical one.
The news that he will leave for Shanghai is true.
B.when和where引导的同位语从句与定语从句的区别。
when 和where前面的名词若是表示时间、地点的名词，则when和where 引导的是定语从句，否则则为同位语从句。如：
They put forward the question where they could get the money.（ 同位语从句）
This is the place where the accident happened.（ 定语从句）5、名词性从句中主句和从句的时态、主谓一致情况
（1）宾语从句中主句和从句的时态保持一致，但如果从句中表示提示的是客观现象，虽然主句是过去时态，从句仍用一般现在时。如：Hello, I didn’t know you were in London. How long have you been here?
The teacher told us that light travels at a very high speed.（2）主语从句作主语相当于单数第三人称作主语，谓语动词用单数，如果由and 连接两个或两个以上的主语从句作主语时，谓语动词用复数；由两个或多个连接词引导一个主语从句，谓语动词用单数。如：When the meeting will begin has not been decided yet.
When they will start and where they go have not been decided yet.
When and where the meeting will begin has not been decided. 6.、宾语从句（The Object Clause）
宾语从句在复合句中起宾语作用，可以作动词的宾语，也可以作介词的宾语。e.g.
1）、做动词的宾语
(1)大部分宾语从句直接跟在动词后：
e.g. He doesn't know where the post office is.
(2)有些宾语从句前要有间接宾语：
e.g. He told me what I should read．
(3)如果宾语从句后面有宾语补足语，要使用形式宾语 it 而将从句放到补足语后面；
e.g. I thought it strange that he failed to call me．
我觉得奇怪：他没给我打电话。
(4)在think, believe, suppose, expect等动词之后的宾语从句中，如果从句谓语是否定含义，则不用否定形式,而将主句谓语动词think等变为否定形式;
e.g. I don’t think you are right．我想你是不对的。
(5) 在think，believe，imagine，suppose，guess，hope等动词以及I’m afraid 等后，可用so代替一个肯定的宾语从句，还可用not代替一个否定的宾语从句：
e.g. 一Do you believe it will clear up?你认为天气会转晴吗?
一I believe so. 我认为会这样。
I don't believe so.(或I believe not.)
我认为不会这样。
2）、 做介词的宾语：It depends on whether we have enough time.但that引导的宾语从句只有在except, in, but, besides等少数介词后偶尔可能用到;
e.g. Your article is all right except that it is too long．
7. because, as if, as though 引导的表语从句
because引导表语从句通常只用于“This/That/It is because…”结构中。
as if/though引导的表语从句常置于连系动词look, seem, sound, be, become等后面，常用虚拟语气，表示不存在的动作或状态。
e.g. It sounds as if/though somebody was knocking at the door. My anger is because you haven’t written to me for a long time.
名词性从句是高考英语的重点考查内容之一，掌握其常见考点对提高应试技能很有益处。
高考常见考点：
一、陈述句语序问题：名词性从句必须用陈述句的语序。
e.g. I didn't know what ____with her.
A. was the matter
B. is the matter
C. Matter
D.the matter is 【A】
二、形式主语和形式宾语it的用法：在英语中只有 it 可以做形式宾语，this/that 不行。
e.g. Don‘t take it for granted that he will help us. He makes it a rule that he gets up early every morning.
三、在某些动词，如think, expect, suppose, believe, guess等后的宾语从句中，如果是否定形式，其否定副词not要提前到主句谓语动词上。
e.g. I don't think he is honest. I don't believe he can do it alone.
五、whether 和 if 的区别：
1）引导表语从句，同位语从句和主语从句，用whether, 不用if 。
e.g.
The question is whether the film is worth seeing.
The news whether our team has won is unknown.
Whether we shall attend the meeting hasn't been decided.
2）引导宾语从句一般两者皆可， 但在介词后常用whether，在whether or not中whether不用if代替。
e.g.
I don't know whether or not he is going to see the film.
It depends on ____we have enough time. A. if B. weather C. if or not D. whether 【D】
六、注意 I doubt whether/ if..., I don't doubt that..., There is some doubt whether..., There is no doubt that...的用法：e.g. Although most of them have no doubt ____he will pass the exam. I still think there is some doubt ____he has really got everything ready.
A. whether; that
B. that; whether
C. that; that
D. whether; whether 【B】
七、注意 I'm sure that..., I'm not sure whether...的用法：
e.g. I'm sure that he is honest. I'm not sure whether he will come.
八、注意 The reason...is that...的用法：
e.g. The reason why he was late was that it was raining.
九、注意what/whatever, who/whoever, which/whichever, where/wherever 等的区别：what等连接代词或副词表示疑问，whatever等连接代词或副词加强语气：
e.g. ____comes to the party will receive a gift.
A. Which
B. Who
C. Which one
D. Whoever 【D】
十、注意whatever等和 no matter what等 的区别：
whatever等既可以引导名词性从句，而可以引导让步状语从句，no matter what等只能引导让步状语从句：
e.g. No matter what he says, （让步状语从句） I will believe him.
I believe whatever he says. （宾语从句）
十一、注意It's important/ necessary/ strange/ natural/ possible/ impossible/surprising...that...的用法：
e.g. It's necessary that we should practice reading English every day.
十二、注意It's said/ reported/ thought/ considered/ suggested/ hoped/ found/ believed...that...等的用法：
e.g. It's reported that ten people were killed in the road accident.
十三、掌握What + vt. + sb. most + is/was + that...句型的用法：可以用于该句型的常见动词有：
astonish / impress / move / shock / surprise ...
e.g. What impressed me most was that all of them studied very hard.
十四、注意what's the matter/what the matter is的区别：
e.g. He asked me what was matter with me.(他问我怎么了）
The teacher asked me what the matter was. (老师问我那是什么物质)

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

名词性从句讲解 在复合句中起名词作用的从句叫做名词性从句。它包括主语从句、宾语从句、表语从句和同位语从句。名词性从句是中学阶段的一个重要语法项目，在历年的高考中几乎都涉及到，并且每年的命题各有变化。分析历届高考试题名词性从句考查的焦点主要有以下六个方面 1. 考查名词性从句的语序问题 2. 考查引导词that与what的区别 3. 考查it在名词性从句中作形式主语或形式宾语的用法 4. 考查whether与if的区别 5. 考查名词性从句中的疑问词+ever引导的名词性从句与no matter+疑问词引导的状语从句的区别 6. 考查名词性从句的虚拟语气问题 语法要点剖析 一、名词性从句 主语从句、表语从句、宾语从句、同位语从句，在整个句子中所起的作用，相当于一个名词。因此，这四种从句通称为名词性从句。 引导名词性从句的连接词可分为三类： 连接词：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 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： What he wants to tell us is not clear. 他要跟我们说什么，还不清楚。 It is known to us how he became a writer. 我们都知道他是如何成为一名作家的。 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 + 名词+ that从句（2）It + be + 形容词+ that从句 （3）It + be + 动词的过去分词+ that从句（4）It + 不及物动词+ that 从句 另注意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 … It is a pity (a shame, no wonder, etc.) that… It is suggested (requested, proposed, desired, etc.) that… 2. 宾语从句 名词句用作宾语的从句叫宾语从句。引导宾语从句的关联词与引导主语从句表语从句的关联词大致一样，在句中可以作谓语动词或介词及非谓语动词的宾语。 1. 由连接词that引导的宾语从句 由连接词that引导宾语从句时，that在句中不担任任何成分，在口语或非正式的文体中常被省去，但如从句是并列句时,第二个分句前的that不可省。例如： He has told me that he will go to Shanghai tomorrow. 他已经告诉我他明天要去上海。 We must never think (that) we are good in everything while others are good in nothing. 我们决不能认为自己什么都好，别人什么都不好。 注意：在demand、order、suggest、decide、insist, desire, demand, request, command等表示要求、命令、建议、决定等意义的动词后，宾语从句常用“（should）+ 动词原形”。例如： I insist that she (should) do her work alone. 我坚持要她自己工作。 The commander ordered that troops (should) set off at once. 司令员命令部队马上出发。 2. 用who，whom, which, whose, what, when, where, why, how, whoever, whatever, whichever等关联词引导的宾语从句相当于特殊疑问句，应注意句子语序要用陈述语序。 例如：I want to know what he has told you. 我想知道他告诉了你什么。 She always thinks of how she can work well. 她总是在想怎样能把工作做好。

名词性从句 名词性从句是由if, whether, that 和各种疑问词充当连接词所引导的从句，其功同名词一样。 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。被强调部分指人是也可用who/whom。例如：
It is a pity that you didn't go to see the film. It doesn't interest me whether you succeed or not. It is in the morning that the murder took place. It is John that broke the window. 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… (3) it is ＋不及物动词＋从句
It seems that… 似乎… It happened that… 碰巧… (4) it ＋过去分词＋从句 It is reported that… 据报道… It has been proved that… 已证实… 3. 主语从句不可位于句首的五种情况 (1) if 引导的主语从句不可居于复合句句首。 (2) It is said , (reported) …结构中的主语从句不可提前。例如： It is said that President Jingo will visit our school next week. (right) That President Jiang will visit our school next week is said. (wrong)
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
