四类名词性从句详解
四类名词性从句详解
所谓名词性从句，就是指其作用相当于名词的从句，它包括主语从句、表语从句、宾语从句和同位语从句。
一、主语从句
1.引导词：主语从句就是在复合句中用作主语的从句，引导主语从句的引导词主要有三类：一是that；二是whether；三是那些可以用作疑问词的词语，如what, who, which, when, where, how, why等。如：
That we shall be late is certain. 我们要晚了，这是确定无疑的。
What he says is not important. 他说的话并不重要。
How this happened is not clear to anyone. 这件事怎样发生的，谁也不清楚。
Which side wins makes no difference to him. 哪边赢他都无所谓。
Whether it will do us harm remains to be seen. 是否对我们有害还要看一看。
2.形式主语：有时为了避免句子显得“头重脚轻”，可用it作形式主语放在句首，而把真正的主语放在句末。如：
It’s a pity that he didn’t come. 很遗憾他没来。
It’s not yet known what she did. 她做什么还不得而知。
It was uncertain whether he could come or not. 他是否会来还不肯定。
这三句句首的it均为形式主语，相应的真主语分别是that he didn’t come / what she did / whether he could come or not。
二、表语从句
表语从句就是在复合句中用作表语的从句。一般说来，可用于引导主语从句的引导词也可用于引导表语从句，如that, what, who, which, when, where, how, why, whether等。如：My idea is that we should do it right away. 我的意见是马上就干。
That is what he meant. 这就是他的意思。
The problem is how we can find him. 问题是我们如何找到他。
The morning is when I’m busiest. 早上是我最忙的时候。
That’s where you are wrong. 这就是你不对的地方。
That’s why he didn’t come. 这就是他没有来的缘故。
另外，表语从句还可以用as if, as though, because等来引导。如：
It is because he is too foolish. 那是因为他太蠢了。
It is not as though we were poor. 又不是我们家里穷。
三、宾语从句
1.引导词：宾语从句就是在句中用作宾语的从句。一般说来，可用于引导主语从句的引导词也可用于引导宾语从句，如that, what, who, which, when, where, how, why, whether 等。如：
We believe that he is honest. 我们相信他是诚实的。
She has got what she wanted. 她要的东西得到了。
I haven’t decided whether I should go. 我还没决定我是否会去。
I asked how he was getting on. 我问他情况怎样。
He asked when the train would get in. 他问火车什么时候进站。
He asked me where I was going. 他问我到哪儿去。
Please tell me which you like. 告诉我你喜欢哪一个。
He asked who lived next door. 他问谁住在隔壁。
She asked why he was silent. 她问他为什么一言不发。
2. if与whether：if通常不用于引导主语从句或表语从句，但可以用于引导宾语从句，与whether用法相同，常可互换。如：
I wonder if it’s large enough. 不知它是否够大。
She didn’t say if he was still alive. 她没说他是否还活着。
但是，当于用于介词后引导宾语从句时，只能用whether，不能用if。如：
I worry about whether I hurt her feelings. 我为是否伤了她的感情而忧虑。
3. that的省略：that引导主语从句或表语从句时通常不省略，但引导宾语从句时通常可以省略。如：
She said (that) she didn’t want to know. 她说她不想知道。
I don’t think (that) she’s interested in it. 我想她对这事没有兴趣。
4.否定转移：当主句主语为第一人称，且主句谓语动词为think, believe, suppose, expect, imagine等时，若其后接一个表示否定意义的宾语从句，此时通常应将否定转移到主句上。如：
I don’t think that he will leave. 我认为他不会离开。
I don’t believe that it is easy. 我相信这不会容易。
四、同位语从句
在复合句中用作同位语的从句叫同位语从句。所谓同位语，就是指两个语法单位指同
一个人或事物，并且句法功能也一样，此时我们就把后一项称为前一项的同位语。所谓同位语从句，就是指用于名词后对该名词的内容进行说明解释的从句。如：The judge paid no attention to the fact that she had just lost her husband. 法官毫不考虑她刚刚失去丈夫一事。
句中的that she had just lost her husband为修饰名词the fact的同位语从句，用以具体说明the fact的内容。
Mary suddenly got the feeling that someone was watching her. 玛丽突然感到有人在看她。
句中的that someone was watching her为修饰名词the feeling的同位语从句，用以具体说明the feeling的内容。
英语中只有少数名词可后接同位语从句，比较常见的有belief, doubt, fact, feeling, hope, idea, message, news, opinion等。
另外，同位语从句的引导词也比较有限，主要是由that引导，有时可也可用when, how, where, whether, who等引导，但是不能用if也引导，也不能用what来引导。如：Y ou have no idea how worried I was! 你不知道我多着急!
He had no idea why she left. 他不知道她为什么离开。
There is some doubt whether he will come. 他是否会来还不一定。
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，同时可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 abroad 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）
2)The 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）

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

(完整版)名词性从句讲解及专项练习习题及其解答
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。

高中名词性从句讲解
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 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 broke 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… (3) It is ＋不及物动词＋从句 It seems that…似乎… It happened that…碰巧… It appears that…似乎… (4) It ＋过去分词＋从句 It is reported that…据报道… It has been proved that…已证实… It is said that…据说… 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： 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 next week is said. （3）It 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 examination. 错误表达：That he failed in the examination occurred to him. （4）It 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 not.

高中英语从句大全 一．名词性从句 起名词性作用的从句叫名词性从句英语当中其名词性作用的成分有主语，宾语，表语，同位语，当这些成分有一个句子来代替就构成了名词从句，主要有主语从句，宾语从句，表语从句，同位语从句。 1.表语从句 1.定义：用作表语的从句叫做表语从句。（be动词,四“变得”：become, get,turn，go；感官动词look,, smell,sound，taste，feel；及grow, turn out，appear，keep等） 引导表语从句的词有从属连词that、whether、as though(if)； 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。 可以接表语从句的连系动词由be, look, remain, seem等。 The trouble is that we are short of money.

At that time, it seemed as if I couldn't think of the right word anyhow 2、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，在口语中，间或可以省略。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，trouble，problem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。 The trouble is that I have lost his address The question is whether they will be able to help us.问题是他们是否能帮我们。 The trouble is (that) she has lost his money. The question is whether we need more ice cream. The problem was that it was too valuable for everyday use. What she could not understand was that fewer and fewer students showed interest in her lessons. 3、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。 The question is which of us should go. The problem was who could do the work.. That's what he is worrying about. That's what we should do. The problem is who we can get to replace her.问题是我们能找到谁去替换她呢。 The question is how he did it.问题是他是如何做此事的。 That was what she did this morning on reaching the attic.那就是她今晨上了阁楼干的。 4、由关系副词引导的表语从句。 Go and get your coat.

四种名词性从句讲解与练习
四种名词性从句（宾语从句、主语从句、同位语从句、表语从句）讲解与练习 学习宾语从句 学习宾语从句的连词、语序、时态和各种变化及特殊用法（直接引证变间接引语也在宾语从句的基础上还要进行人称、状语、少数动词和句型的变化)是为学习其它三种名词性从句（主从、表从、同位从）做铺垫，连词、语序、时态基本相同，只是后三种考点相对宾语从句少的多，主要是对连词的应用进行考查。所以学好宾语从句是必要的。 宾语从句三注意三特殊 一注意：注意引导词（连词） 由陈述句转化而来的宾语从句，引导词为that，that在口语或非正式文体中可省略；由一般疑问句转化而来的宾语从句，引导词为if或whether；由特殊疑问句转化而来的宾语从句，引导词为句子本身的特殊疑问词，即what，when，where等。例如：Tom says (that) he will fly to Beijing tomorrow. 汤姆说他明天将要坐飞机去北京。 He asked me if / whether I know his name. 他问我是否知道他的名字。 I want to know where you went yesterday. 我想知道你昨天去哪儿了。 二注意：注意从句语序 宾语从句的语序应该为陈述句语序，即“主语+谓语+宾语+其他”。也就是说，将疑问句转化成宾语从句时，一定要将疑问句语序转变成陈述句语序。例如： Can you tell me what he is doing? 你能告诉我他正在做什么吗？ <特别提醒> 当疑问句在宾语从句中做主语时，语序不变。例如： Do you know what makes him so angry? 你知道什么事使他如此生气吗？ I don’t know what is wrong with her.我不知道她出什么事了。 三注意：注意从句时态 主句为一般现在时态，则宾语从句根据实际情况用任意的时态；但主句为一般过去时态时，宾语从句则要用过去的相对应的某种时态。例如： She tells me that she will come by train. 她说她将要坐火车来。 She told me that she would come by train. 她说她将要坐火车来。 <特别提醒> 如果宾语从句表示的是客观真理或是科学事实，其谓语动词仍用一般现在时态。例如： Our teacher told us that the sun is much bigger than the moon.
名词性从句用法讲解与专项练习题及答案
名词性从句用法讲解与专项练习题及答案 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。高考常从连接词的选择、语序、语气、时态等方面来考查。名词性从句中的连接词有连词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。 第1讲引导名词性从句的连接词 考点1. 引导名词性从句的连接词有哪些 有学生认为，引导同位语从句只能用that, 这句话对吗？先看下面几个句子。 ①I have no question that he will come. ②I have a question whether he will come ③I have a question when he will come. 我们可以看出：上面三个句子中question后面都是同位语从句，都是说明question的内容的。 在句①中，同位语从句的原句是陈述句，由that引导；在句②中，原句是一般疑问句，由whether引导； 在句③中，同位语从句的原句是特殊疑问句，特殊疑问词也起着连接作用。 其实，所有名词性从句的连接词都有上面的三种情况。
宾语从句： I don’t know that he will come. I don’t know whether/if he will come. I don’t know when he will come. 表语从句： What I don’t know is that he will come. What I don’t know is wheth er he will come. What I don’t know is when he will come. 主语从句 That he will come is obvious. Whether he will come isn’t known yet. When he will come isn’t known yet. 1. 【2010浙江】It is uncertain ______ side effect the medicine will bring about, although about two thousand patients have taken it.
