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, 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。

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。
高考英语复习 名词性从句讲解
名词性从句一、名词性从句与简单句的区别在英文中，名词或名词短语主要充当四种句子成分：主语、宾语、表语和同位语。
如果把句子当作名词来用，分别充当另一句话的主语、宾语、表语或同位语，于是便构成了四种从句：主语从句、宾语从句、表语从句和同位语从句。
因为这四种从句在本质上相当于名词的作用，所以将其统称为名词性从句。
请看下表：在英语中，相当于名词作用的句子有三类，陈述句、一般疑问句以及特殊疑问句。
因此，名词从句就是用三种句子来分别充当另外一个句子的四种句子成分，者就构成了名词从句的本质特征。
但是，这三种句子不是直接放在另一个句子中作成分，而是要作各种变化调整。
接下来将具体讨论。
二、陈述句作句子成分1. 要在陈述句句首加上t hat用”that+陈述句”这一结构分别充当另一个句子的四种成分。
2.为什么要加that?对于陈述句，为什么要在其句首加that 后才能用它作成分呢？而为什么在宾语从句中that 又可以省去呢？因为在英文中，句子的核心意思主要是靠谓语部分来表达，一个句子只表达一个核心意思，也就是只能有一个谓语部分。
而添加that，相当于一个“指路牌”，能够帮助我们指明段句的方向，而不至于造成歧义。
而对于宾语从句，主句的谓语已经出现，后面所接的成分自然是谓语，所以在不会影响句子的意思下，是可以把that 省去的。
三、一般疑问句作句子成分1.用w hether 或if 引导先将疑问句的倒装语序变成陈述句语序(即主语放在谓语的前面)，并在句首加上whether 或if（if 只用在宾语从句中）来引导，以保留原句的疑问意义。
即“whether+陈述句”2. if 还是 whether?1)if 一般只用于引导宾语从句，而 whether 可引导宾语从句在 内的其他名词从句。
IF he comes or not makes no difference. 成 Whether he comes or not makes no difference.2)if 不和 or not 直接连用，即一般不说 if or not, 但可以说 if...or not 。

名词性从句的考查要点：(1) What ,that 引导名词性从句的区别; (2) Whether ,if 引导名词性从句的区别; (3) 同位语从句和定语从句的区别； 一、 名词性从句概述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, 它在复合句中能担任主语、宾语、表语、和同位语，因此根据它在句中充当不同的语法功能，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。
二、名词性从句比较请注意1、名词性从句中的that 省略情况：动词后的宾语从句和表语从句中的that 可以省略。
2、No matter +wh-开头的词如no matter what 等只能连接让步状语从句。
而wh-开头的词+ever 如whatever 等既能连接让步状语从句，也能连接名词性从句。
解题步骤和原则：分析复合句结构，找出从句，确定名词性从句中的哪一类。
分析从句，结合上表中各个连接词的特点，缺什么补什么。
主语从句中It 作形式主语常用句型：1.It + be +形容词（obvious, true, natural, possible, likely, probable, certain, wonderful, good, etc.） + that 从句2. It + be +名词词组(no wonder ，a pity ，an honor, a good thing, no surprise , etc.) + that 从句3. It + be + 过去分词(said, thought, reported, expected, announced, decided , etc.) + that 从句4. It +不及物动词(seem, happen, etc.) + that 从句5. It doesn ’t matter(make no different , etc.) + 连接代词或连接副词引导的主语从句Eg: It is certainthat she will do well in her exam. Eg1.(2012课标·全国I) It is by no means clear__________ thepresident can do to end the strike.A.howB. whichC. thatD. what2.(2012天津，7)It doesn’t matter _______you turn right or left at the crossing — both roads lead to the park.A. whetherB. howC. ifD. when3.(2012江西，25) It suddenly occurred to him_________ he had left his keys in the office.A. whetherB. whereC. whichD. that1. if /whether表示“是否” 可以互换,但以下情况只能用whether，不用if. （1）在介词后面Eg：Everything depends on whether we have enough time.（2）与or not连用Eg：I don’t know whether he will come or not.（3）宾语从句提前时Eg：whether they can come here on time, we don’t know.（4）后面跟不定式Eg：I really don’t know whether to accept or refuse.2. 宾语从句的时态（一般来说，主从句时态要统一。

名词性从句一，名词性从句的概念：1, 相当于名词，分为主语从句、表语从句、宾语从句和同位语从句2，名词性从句的引导词：that, whether, if (一般是宾语从句)，as if(表语从句)，who, whom, whose, what, which, when, where, why, how,以及由how组成的词组，如：how many, how long, how far两组需要注意的连接词that/what1）that和what都可以引导名词性从句，但that是连接词，本身无词义，仅起连接作用，不在从句中担任任何成份；what是连接代词，不仅引导名词性从句，而且在从句中充当一定的成份，如主语、宾语或表语。

完整版)高中英语名词性从句详解名词性从句可以作为主句的主语、表语、宾语和同位语。

高考英语名词性从句详解
高考英语名词性从句详解易错点引导词what 与that 的区别；引导词whether 和if 的区别；名词性从句的语序；who / whoever，what / whatever 等的区别；where，when，why 等连接副词引导的名词性从句；“介词+ who（m）”引导的宾语从句与“介词+who（m）”引导的宾语从句的区别；名词性从句中有插入成分时；引导词that 的省略；同位语从句引导词where，when 的用法特点一、引导词what 与that 的区别引导主、宾、表语从句时，what 要充当主语、宾语或表语等句子成分，that 不作任何成分，而只在语法上起连接作用。
例如_________ we can’t get seems better than _________ we have.A. What；whatB. What；thatC. That；thatD. That；what解析：本句包含一个主语从句和一个宾语从句，且两个从句都缺乏宾语，可见两个引导词都必须充当从句的宾语，所以答案为A 项。
在下面的例句中，that 不充当任何成分，只起语法连接作用（因为句子本身不缺成分）：That the former Iraq president Saddam was captured has been proved.二、引导词whether 和if 的区别通常，引导主语从句、表语从句和同位语从句时，连词要用whether，而不用if ；习惯上也只能说whether or not，而不说if or not .例如：_________ the meeting will be held in Beijing is not known yet.A. WheneverB. IfC. WhetherD. That解析：题中的从句位于句首，不难知道这是一个主语从句，根据句意，答案为 C 项。
但如果宾语或主语从句为否定句时，只能用that，不能用whether 引导。

高考英语名词性从句讲解一、概念：名词性从句相当于名词词组，在复合句中起名词性作用。
分类：主语从句、表语从句、宾语从句和同位语从句。
引导名词性从句的1）连接词：that, whether, if;2）关系代词：who, whom, whose, what, which, whatever, whichever;3) 关系副词：when, where, how, why.二、要点：人物主语：who, whoever what, whatever宾语：whom, whomever what, whatever名词性从句表语：whom what定语：which what whose状语when where why how whenever however wherever不做成份：that if/whether as if /as though三、基础知识学习：1主语从句: 主语从句是在复合句中代替作主语的名词, 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.that 引导的主语从句①句首That a round-trip to Mars would take more than a year and a half is estimated.That he misunderstood me is obvious.That引导主语从句，放句首，不做任何成分，不可省略。
②用形式主语it来引导句子A. that引导主语从句放句首时，有时会为了避免头重脚轻，保持句子平衡，常用it做形式主语，把真正的that引导的主语从句放句后。
It is strange that he made no answer.It is known to all that the earth is round.B. 用it做形式主语的主语从句结构注意：i. 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。

主语从句中应注意的问题 1）主语从句在句首时，必须由连接词引 导，不能省略这些连接词。 误： The college will get in more new students this year is ture. 正：That the college will get in more new students this year is ture. 2)如果主语从句放在句首，不能用if引导， 但是如果用it 做形式主语，而把主语从句 放在句末时，也可以用if引导.

适用文档名词性从句解说在复合句中起名作用的从句叫做名性从句。
它包含主从句、从句、表从句和同位从句。
名性从句是中学段的一个重要法目，在年的高考取几乎都波及到，而且每年的命各有化。
解析届高考名性从句考的焦点主要有以下六个方面1.考名性从句的序2.考引 that与 what 的区3.考 it 在名性从句中作形式主或形式的用法4.考 whether 与 if 的区5.考名性从句中的疑+ever 引的名性从句与no matter+ 疑引的状从句的区6.考名性从句的虚气法重点解析一、名性从句主从句、表从句、从句、同位从句，在整个句子中所起的作用，相当于一个名。
所以，四种从句通称名性从句。
引名性从句的接可分三：接： that, whether, if（不充任从句的任何成分）接代： what, whatever, who, whoever, whom, whose, which.接副： when, where, how, why1.主从句作句子主的从句叫主从句。
主从句往常由附属that ，whether ，if和接代what ，who，which ，whatever ， whoever 以及接副 how， when， where， why 等引。
that 在句中无，只起接作用；接代和接副在句中既保存自己的疑含、又起接作用，在从句中充任从句的成分。
比如：What he wants to tell us is not clear.他要跟我什么，不清楚。
It is known to us how he became a writer.我都知道他是如何成一名作家的。
Where the English evening will be held has not yet been announced.英晚会将在哪里行，没有宣告。
有防止句子重脚，常用形式主it取代主从句作形式主放于句首，而把主从句置于句末。
主从句后的一般用数形式。
