高中英语语法之名词性从句
高中英语语法之名词性从句第一节基本知识与基本概念【什么是名词性从句？】上一章，我们了解的是定语从句，加上我们以前了解的宾语从句和状语从句，好像“名词性从句”只是，在平时老师讲课时，形容词性从句和副词性从句并没有形成气候罢了。
相比之下，名词性从句由于“家丁兴旺”而大行其道。
但是，作为学生，我们有必要了解这些基本概念的来龙去脉。
【主语从句】顾名思义，主语从句在句子中作主语。
有时本身出现在主语的位置上，也有时出于句子结构的考虑退到句子的尾部，前面用形式主语it代替。
从句作主语时，谓语动词一般为单数形式。
如: What I saw was beyond any verbal description.That his hair was turning grey worried him a bit.Why the company denied the contract is still unknown.When and where the government will build a city square is under discussion.It is pretty annoying that a small part of the machine is missing.It remains to be seen whether the new novel will be well received.【宾语从句】在句子中作宾语的从句就是宾语从句。
由于这是同学们接触比较早的一种从句，应该问题不大。
所以在近年的高考题中，以宾语从句的知识作为考点的题目较少。
但是，宾语从句也有自己的特殊情况，如介词的宾语，形容词的宾语，宾语从句提前和并列的宾语从句等现象。
如：We assumed that there would be more than 100 guests.He told the police in detail what he saw and heard.Nobody is sure what humans will look like in a million years.That will depend on whether they can get the chance.Whether I will have the time I am not sure at the moment.The conductor complained that we were not gifted in singing and that he would never come again.【表语从句】表语从句的最重要脸谱就是它们应该出现在系动词的后面。
如：The only question left is how often the workers are paid.His idea for the coming weekend is that we go skating.【同位语从句】从脸谱上看，同位语从句最为麻烦。
因为它们也是出现在一个名词的后面，起着解释说明的作用。
有点像定语从句。
这个点是许多学生容易混淆的地方。
但是，只有我们能把握住关键，即：定语从句的先行词在从句中必须作一个成分，并且这个成分应该是个空白，也就是说，定语从句必须缺少成分。
这一点恰恰是同位语从句所不能做到的。
同位语从句前面的名词在从句中是没有位置的。
况且，也不是所有的名词后面都会跟同位语从句，只有那些“有内容的名词”才需要解释。
如fact, news, idea, truth, hope, problem, information, belief, thought, doubt等。
如：That fact that the policeman didn’t fire at the man at all was ignored.Do you have any idea what is going on in the classroom.The possibility that we can work at home makes everybody excited.尽管同学们在这个方面有诸多问题，但好消息还是有的，在新出台的《山东省高考考试说明》中，同位语从句不在必考的名单之中。
大家可以放心了。
【连接代词、连接副词和连接词】通过以上介绍，我们可以看出，四种名词性从句都需要有一个连接性词在从句的开头。
这个词是什么性质，要看它在从句中作作的成分，如果作的是主语、宾语、表语的话，这个词就是连接代词；如果作的是各种状语，就叫连接副词；如果不作任何成分，就叫连接词。
如下表：连接词that, if, whether引导名词性从句的连接词连接代词who, whom, what, whose, which, whichever, whatever, whoever连接副词when, where, how, why第二节考点分类解析【考点一：语序问题】名词性从句的语序问题一直断断续续地在各地高考题目中出现，由此可见其重要性。
其实说来非常简单易记：永远陈述语气。
即名词性从句中不会出现助动词提前的现象。
如：Who he is doesn’t matter much.When and where we shall have the sports meet is a question.I don’t know what his name is.I don’t know what is wrong with him. = I don’t know what is the matter with him.You can’t imagine how excited I was at that time.Can you tell me what size shoes you wear?No one can be sure ______ in a million years. （MET1991）A. what will man look likeB. what man will look likeC. man will look like whatD. what look will man like答案：B。
这个题就是典型的考查宾语从句的语序问题。
根据以上所述，应该是陈述语序。
所以A、C 两个选项就不可能了。
而D选项明显不符合我们的语言习惯。
【考点二：that和what的区别问题】能引导名词性从句的关系代词有who, whom, what, whose, which, whichever, whatever, whoever八个。
为何单独讲what的用法呢？重要！在考试中出现的频率高！在本书第一章《定语从句》中，我们提到过，what是不能引导定语从句的。
定语从句中如果缺少的成分是主语、宾语、表语，我们选择的是关系代词that或其他。
现在山头换了，到了名词性从句的知识范围了。
What在名词性从句中就很有用武之地了。
还是分析成分，what 在从句中作的主语、宾语、表语。
而that只是一个“连接词”，既不作什么成分，也没有什么意义。
如:What you did doesn’t agree with what you promised.What he couldn’t understand was why his teacher was never satisfied with him.The matter of salary is what I care most if I decide to change my profession.What we can’t get always seems better than what we have already got.I think that your composition is no better than his.That you don’t love her is not my business.What we have seen is different from _______.A. we heardB. we have heardC. what we heardD. what we have heard答案：D。
我们应该可以看出这是个宾语从句。
从句中hear是个及物动词，缺少宾语。
所以，应该选有what引导的从句。
而不能是that或者省略了that的情况。
I couldn’t agree with ______ at the meeting.A. that you saidB. which you saidC. all what you saidD. what you said答案：Ｄ。
与上一题相同，这也是一个考查宾语从句的题目。
从句中的say是个及物动词，缺少宾语。
所以，应该选择what引导的宾语从句。
但是，这个题目最容易错的选项是Ｃ。
因为有些同学会认为all是先行词，而后面时what引导的定语从句。
但是，从上一章的讲解我们应该学会what是不引导定语从句的。
所以，Ｃ根本就是不存在的。
【考点三：that和whether的区别问题】有时候，它们两个比较难以区别，因为，它们都是连接词，都在从句中不作成分。
但是，它们之间最大的区别在于“意义”。
即that在从句中既不作成分，也没有自己的意义；而whether就不同了。
它虽然不在从句中作什么成分，但是它又意义，即“是否”。
这就能够左右从句的意思，使从句所表达的意思变成一个还没有确定的因素。
如：I don’t know whether he can join us or not.I’m sure that he can join us.It is none of your business whether I love her.It is none of your business that I don’t love her.综上所述，区分that还是whether，重要一点就是看主句需要从句表达一个什么意思，是确定的，还是不确定的；是事实还是疑问。
前者选that，后者选whether。
如：I have no doubt _____ Mr. Johnson will make it here on time.A. thatB. whetherC. whyD. when答案：Ａ。
这个题之所以选择that，就是因为前面的I have no doubt（毫无疑问），这样的主句已经不再需要从句表达什么“是否”了。
No one can be sure _____ the board will accept our conditions.A. thatB. whetherC. whyD. what答案：Ｂ。

高中英语知识点归纳名词性从句与定语从句的区别
高中英语知识点归纳名词性从句与定语从句的区别在高中英语学习中，名词性从句和定语从句是两个常见的语法结构。
虽然它们在形式上很相似，但在功能和用法上有很大的区别。
本文将对名词性从句和定语从句进行归纳和区分。
一、名词性从句名词性从句作为主句的主语、表语、宾语或同位语，起到名词的作用。
名词性从句一般由关系词“that、whether/if, who, whom, whose, which”等引导。
下面将具体介绍名词性从句的几种情况。
1.主语从句一个句子的主语可以被一个从句所替代，这个从句就是主语从句。
例如：What he said puzzles me.（他说的话让我迷惑不解）2.表语从句一个句子的表语可以被一个从句所替代，这个从句就是表语从句。
例如：My dream is that I can travel around the world.（我的梦想是能够环游世界）3.宾语从句一个句子的宾语可以被一个从句所替代，这个从句就是宾语从句。
例如：I believe that he will pass the exam.（我相信他会通过考试）4.同位语从句同位语从句是对前面名词性成分进行解释或说明的从句，常用的引导词是“that”。
例如：The news that he won the competition excited me.（他赢得比赛的消息让我兴奋）二、定语从句定语从句用来修饰或限定名词或代词，并且不能单独存在，必须依附于名词或代词。
定语从句一般由关系代词（that, who, whom, whose, which）或关系副词（where, when, why）引导。
下面将具体介绍定语从句的几种情况。
1.关系代词引导的定语从句The book that I borrowed from the library is very interesting.（我从图书馆借的那本书非常有趣）The boy who is talking to Mary is my brother.（正在和玛丽说话的那个男孩是我的弟弟）2.关系副词引导的定语从句Do you still remember the place where we first met?（你还记得我们第一次见面的地方吗）I still remember the day when we had a picnic in the park.（我依然记得我们在公园野餐的那天）三、名词性从句与定语从句的区别总结名词性从句与定语从句最大的区别在于名词性从句本身是一个句子，可以在句子中充当主语、表语、宾语或同位语；而定语从句是一个从句，用来修饰或限定名词或代词。
高考英语语法知识点：名词性从句
高考英语语法知识点：名词性从句1500字名词性从句是指在句子中充当名词的成分的从句。
名词性从句分为主语从句、宾语从句、表语从句和同位语从句。
在高考英语中，名词性从句是考查的重点之一，我们需要对名词性从句的结构和用法有透彻的理解。
下面是关于名词性从句的一些重要知识点：1.主语从句主语从句在句中充当主语的作用。
主语从句通常以that引导，也可以用whether或if 引导。
例如：- That he is guilty is certain.- Whether we will win the game is yet to be seen.- If it will rain tomorrow is still uncertain.2.宾语从句宾语从句在句中充当宾语的作用。
宾语从句通常以that引导，也可以用whether或if 引导。
需要注意的是，当主句的动词是说、tell、ask、think、believe、know等表示说话、思考、感觉的动词时，常用连词that引导宾语从句，但如果宾语从句的主语与主句的主语相同，可以省略连词that。
例如：- I know that he is a good student.- She asked me if/whether I had finished my homework.- He told her (that) he loved her.3.表语从句表语从句在句中充当表语的作用。
表语从句通常以that引导，也可以用whether或if 引导。
例如：- The fact that he didn't come is disappointing.- The question is whether we should proceed with the plan.- My concern is if/whether we have enough time.4.同位语从句同位语从句用来解释或说明前面名词的具体内容或意义。
2023年高中英语语法：名词性从句用法详解及强化练习分析
2023年高中英语语法：名词性从句用法详解及强化练习分析名词性从句分类简述名词性从句，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。
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 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。

American wedding.
5. 其他连词as if, because, as, as though 引导的表语从句
C．表示某种状态的：remain, keep, prove, continue, stay等.
1. that 引导的表语从句 that 仅起连接作用，无意义，在句中不作任何成分， 通常不可省略。这种从句往往是对主句主语的内容起 进一步解释的作用。
e.g. The chance is that one smoker in four will die from
think等变为否定形式;
e.g. I don’t think you are right．
(5) 在think，believe，imagine，suppose，guess，hope
等动词以及 I’m afraid 等后，可用so代替一个一定的
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
连接副词：when, where, how, why 连接代词和连接副词一般做句子的某一成份
The Subject Clause
用作主语的从句叫主语从句。引导主语从句的 连接词有：
连词that, whether；
连接代词what, whatever, who, whoever, whom, whomever, whose, which,

The question of whether they are male or female is not important. I have not decided whether to go or not.
⑥ whether可引导一个让步状语从句表示 “不管”、“无论”，而if不能，但可以 引导一个条件状语从句表示“如果”如：
• (4)同位语从句 • 就是在句中作同位语的从句。它通常有放在thought, idea, news, word(=news), plan, doubt, question, fact, suggestion, belief等抽象名 词的后面，说明这些词的具体内容或含义。同位语从句大多由that引 导，也可由whether, how, when, where, why等引导，但不能由which 引导。如： • The idea that the earth is round is not a new one. “地球是圆的”这种 观点并不新鲜。He must answer the question whether he agrees to it or not. 他必须回答他是否同意此事这们一问题。 • I have no idea when he will set out. 我不知他什么时候出发。 • 注：有时，同位语从句并不紧跟在它所说明的词的后面。如： • The whole truth came out at last that he was a wolf in sheep’s clothing. 真相终于大白了，他原来是一只披羊皮的狼。
高中英语语法总结-名词性从句
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, 它在复合句中能担当主语、宾语、表语、同位语、介词宾语等，因此依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。
第一节学问点讲解顾名思义，主语从句在句子中作主语。
有时本身出现在主语的位置上，也有时出于句子结构的考虑退到句子的尾部，前面用形式主语it代替。
从句作主语时，谓语动词一般为单数形式。
如:What I saw was beyond any verbal description.That his hair was turning grey worried him a bit.Why the company denied the contract is still unknown.When and where the government will build a city square is under discussion.It is pretty annoying that a small part of the machine is missing.It remains to be seen whether the new novel will be well received.Tips: 主语从句的that确定不能省去。
因为句子是不能做主语的，故用that引导。
若去掉则没有了主语，而宾语从句的that 可省。
主语从句：That he is right is known to all of us.宾语从句：We all know (that) he is right.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改变。
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。
