名词性从句在句子中起名作用的句子叫名性从句(Noun Clauses）。
名性从句的功能相当于名, 它在复合句中能担任主、、表、同位、介等，因此根据它在句中不同的法功能，名从句又可分称主从句、从句、表从句和同位从句。
根据从句在句子中的功能分根据从句的性分定从句形容性从句主从句从句名性从句表从句同位从句状从句副性从句第一知点解一．【主从句】名思，主从句在句子中作主。
有本身出在主的位置上，也有出于句子构的考退到句子的尾部，前面用形式主it 代替。
从句作主，一般数形式。
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: 主从句的that 不能省去。
因句子是不能做主的，故用that 可省。
主从句： That he is right is known to all of us.从句： We all know (that) he is right.1.It 作形式主和 it 引句的比了防止句子重脚，通常把形式主it 放在主位置，真正主置于句末It 作形式主代替主从句，主要是了平衡句子构，主从句的接没有化。
而it 引的句是句子某一部分行，无的是什么成分，都可用that。

注意事项：that在从句中不可省略的情况有：宾语从句中引导词that省略；主语从句中引导词that不可省略；表语从句中引导词that不可省略。

名词性从句的特殊用法
从句中的省略现象
名词性从句(整理完整版)
名词性从句一、定义：名词性从句在功能上相当于名词，是一个句子分别充当另一个句子的主语、表语、宾语和同位语，由此被称为主语从句，表语从句，宾语从句和同位语从句。
辨别下列从句属于哪种名词性从句并分析：1）Why they haven’t left yet is unclear.2）It was good news that everyone got back safely.3）Polly didn’t know which way she should go.4）I’m interested in who that tall man is.5）We all thought it good news that the fog had finally gone.6）My question is whether Polly can find her way home.7）The fact that Polly didn’t ask for the man’s name is a pity.总结：名词性从句主要由陈述句、一般疑问句、特殊疑问句充当。
1）陈述句充当名词性从句时，由that引导；2）一般疑问句充当名词性从句时，由if或whether引导从句；3）特殊疑问句充当名词性从句时，由疑问词本身做连词引导从句。
4）名词性从句的语序应使用陈述句语序，不可用一般问句语序。
二、引导名词性从句的从属连词及从句语序1.连接词that；功能1）不充当句子成分2）无词义3）只起连接作用。
2.if/whether;功能：1）意为“是否”，有词义2）不做句子成分3）起连接作用翻译:1）I know that he will come thisevening.___________________________________________2) Whether we will go there or not hasn’t been decided yet.______________________________3.连接代词：what(ever), which(ever), who(ever), whom(ever), whose(ver)功能：1）有词义2）引起从句3）且在从句中充当一定的句子成分，常做从句中的主语、宾语、表语和定语。

英语名词性从句知识点复习一、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.事实上英语作为国际语言正为世人所接受。
（主语从句）The trouble is that she has lost his address . 麻烦的是她把他的地址搞丢了。
（表语从句）They have no idea at all where he has gone . 他们不知道他去什么地方了。
（同位语从句）Do you remember how he came ? 你记得他怎么来的么？（宾语从句）二、语序名词性从句要采用陈述句语序。
由一个含疑问意义的连词引起时，必须将该连词放在名词性从句的开头，且该从句语序不能倒装。
What we can't get seems better than what we have. 我们得不到的似乎比我们所拥有的要好。
The photographs will show you what our village looks like .这些照片将向你展示我们村庄的面貌。
Can you make sure where Alice has put the gold ring ?你能肯定爱丽丝放金戒指的地方吗？No one can be sure what man will look like in a million years .没有人肯定一百万年后人类会是什么样子。
He asked how much I paid for the violin . 他问我花了多少钱买这个小提琴。
三、时态的呼应名词性从句特别是宾语从句中谓语动词的时态要与主句中谓语动词时态要相呼应，主要有下列几种情况：（1）如果主句中的谓语动词是一般现在时态，从句的谓语动词的时态不受主句谓语动词时态的制约。

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, why1.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。

that 无词义，在从句中不担任成分，有时可省略；if (whether), as if虽有词义，但在从句中不担任成分。
（二）主语从句1、主语从句在复合句作主语。
e.g. Who will go is not important.2、用it作形式主语，主语从句放在句末。
e.g. It doesn’t matter so much whether you will come or not.3、that引导主语从句时，不能省略。
e.g. That he suddenly fell ill last week made us surprised.注意：that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。
(A)It is clear/certain/likely/true/surprising that…(B)It is a pity/shame/good idea/no wonder that...(C)It is said/reported/believed/known/thought/suggested that…（D）It seems/happens that。

名词性从句 文档
主语从句一、概述：在句子中起名词作用的各种从句统称为名词性从句。
根据它们在句中的语法作用，这类从句又可分为主语从句、同位语从句、表语从句和宾语从句。
二、几个共性问题：1．连接方式（1）在由连词that, whether, if引导的名词性从句中，引导词在句中不做成分，在宾语从句和表语从句中，that可以省略。
（2）在由连接代词who, whose, whom, which, what, whoever, whomever, whichever, whatever引导的名词性从句中，其连接代词在句中起名词性作用，担当一定成分。
（3）在由连接副词when, where, why, how引导的名词性从句中，其连接副词在句中作状语。
2．whether和if的区别（1）whether在引导的主语从句中可以置于句首，而if则不能。
（2）whether可以与or not连用，or not可以紧跟在whether之后，也可以置于从句末尾；if一般不能和or not连用。
（3）表语从句、同位语从句和介词宾语从句（即在系词be和介词之后），只能用whether连接，而不用if。
（4）从句是否定式时，一般用if, whether很少用在否定式从句中。
例如：I don’t care if he doesn’t come . 如果他不来，我也不介意。
The problem is whether we can carry out the plan.问题是我们是否能实施这项计划。
三、主语从句1．主语从句主要有三类：（1）由连词that引导的主语从句。
例如：That you will win the medal seems unlikely.你想获得奖牌看起来是不可能的。
That you are so indifferent bothers me.你如此冷淡使我很烦恼。
That she survived the accident is a miracle.她在事故中幸免于难简直是奇迹。

专题02 名词性从句(期中重点语法)知识串讲一、名词性从句的分类（一）根据从句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四种。
（二）根据引导名词性从句的连接词可分为三类：1.连接词：that, whether, if （不充当从句的任何成分）2.连接代词：who, what, which, whose, whoever, whichever, whomever, whatever3.连接副词：where, when, why, how (how much, how long…), wherever, whenever, however二、各个连接词用法及意思。
注：whether与if：只有在及物动词后引导宾语从句，且不与or not 直接连用时，可以互换。
其余的主，宾，表，同位从句中都用whether.主语从句结构及用法在句子中担当主语的从句就叫做主语从句，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。
通常结构为“引导词+ 主语+ 谓语+ 其他成分"。
一. 概念：在句子中担当主语的从句就叫做主语从句，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。
主语从句使用陈述语序，其通常结构为“引导词+ 主语+ 谓语+ 其他成分", 但当连接代词同时充当从句主语时，其结构为“连接代词+ 谓语+ 其他成分”。
二. 引导词：引导主语从句的词有连词：that, whether, if；连接代词：what, whatever, who, whoever, whom, whomever, whose, which, whichever；连接副词：when, whenever, where, wherever, how, however, why。
1. 连词that, whether, if引导的主语从句that在主语从句中不作成分，没有意思，不能省略；whether和if虽不作句子的成分，但有“是否”的意思，且if引导的主语从句不能位于句首。
