【英语】2014年高考英语语法讲解名词性从句

高中英语名词性从句知识讲解以及练习题附答案一、名词性从句概述名词性从句是一种充当名词作用的从句，通常在主句中作主语、宾语、表语或同位语。

它通常由引导词（如that, whether, if, who, whom, whose, which, what等）引导，并且从句中含有一个主语和谓语。

名词性从句的种类有很多，包括主语从句、宾语从句、表语从句和同位语从句等。

下面我们将逐一介绍这些从句。

二、主语从句主语从句作为一个名词，通常位于句首，是一个句子，主要作用是作为主句的主语。

引导主语从句的词：What (什么)；Whether (是否)；If (是否)；That (那个)。

例句：What he said is true. (他说的是真的。

)Whether it will rain tomorrow is uncertain. (明天是否会下雨还不确定。

)If you go, I will go too. (如果你走，我也跟着走。

)That he is coming is good news. (他来的消息是好消息。

)注意：主语从句的谓语动词通常要用单数形式。

What引导的主语从句通常用来表示“事物”的概念。

三、宾语从句宾语从句是一个名词，通常位于主句的动词后面，作为主句的宾语。

它可以由常见的宾语从句引导词引导，例如whether, if, that, who, whom, whose, what, when, where, how等。

引导宾语从句的词：Whether (是否)；If (是否)；That (那个)；Who (谁)；Whom (谁)；Whose (谁的)；What (什么)；When (何时)；Where (何处)；How (如何)。

例句：I know that he is coming. (我知道他要来。

)I wonder if he is telling the truth. (我想知道他是否说了真话。

语法复习之名词性从句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，名词性从句厅分为主语从句、表语从句、宾语从句和同位从句。

（一）引导名词性从句的连接词1、连接代词：who, whose, whom, what, which。

有词义，在从句中担任成分，如主语、表语、宾语、或定语等。

2、连接副词：when, where, why, how。

有词义，在从句中担任成分，作状语。

3、连接词：that, whether, if, as if。

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。

注意：连接代词与连接副词在句中不再是疑问句，因而从句中谓语不用疑问式。

连接代词与连接副词在从句充当句子成分，连接词whether 和if（是否），as if（好象）在从句中不充当句子成分，只起连接作用。

根据句义，如果连接代词与连接副词，whether、if 和as if都用不上时，才用that作连接词（that本身无任何含义）。

（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.（三）表语从句1、表语从句在复合句中作表语，位于系动词之后。

e.g. The question was who could go there.2、引导表语从句的连接词that有时可省去。

e.g. My idea is (that) we can get more comrades to help in the work.（四）宾语从句1、宾语从句在复合句中作宾语。

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。

高考英语名词性从句讲解【最全版】Review: 英语句子的种类有两种，按句子的用途可分为陈述、疑问、祈使和感叹句四种。

而按句子的结构可分三种：1）简单句主语+谓语主语+谓语+宾语主语+系动词+表语主语+谓语+间宾+直宾主语+谓语+宾语+宾补2）并列句简单句+并列连词+简单句3) 复合句主句+引导词+从句判断下列句子是简单句，并列句，还是复合句？1.He often reads English in the morning.2.You help him and he helps you.3.My suggestion is that we should study step by step.4.Both Tom and Mike are American boys.5.He said that he has known all before.复合句：主句+引导词+从句定语从句【定义】起定语作用，用来修饰名词或代词的从句。

名词性从句1、主语从句2、宾语从句3、表语从句4、同位语从句在英语的句子结构中，如果本该由名词充当的主语、宾语、表语和同位语，由一个句子来充当，那么这个句子就叫__名词性从句__。

【定义】起名词性作用的从句，叫名词性从句。

换言之，在英语的句子结构中，本来该由名词充当的主语、宾语、表语和同位语部分，换由一个句子来充当，这样的句子就是名词性从句。

关联学习：Related Conception (相关概念)表示人或事物的名称的词叫名词。

The boy is Li Ming.主语：The boy 名词，表语：Li Ming 名词Miss. Liang , a 24-year-old girl, teaches us English . 主语：Miss. Liang 同位语：a 24-year-old girl 宾语： English名词在句中主要作主语、宾语、表语和同位语。

1. The boy is Li Ming.2. What he said is correct.在句中充当主语的从句叫做主语从句。

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 , 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，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。

第一节知识点讲解顾名思义，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 绝对不能省去。

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。

名词性从句一、知识储备种类作用常用关联词例句主语从句在复合句中做主语，相当于名词，一般置谓语之前，也可用it作形式主语，主语从句放主句之后that,whether, if,as if, asthough, who,whose, which,how, when,where, why,what,whatever,whoever,whereverWhether he will come or notdoesn’t matter much.Whoever comes here will bewelcome.表语从句在复合句中做表语，相当于名词，位于系动词之后It looks as if it is going tosnow.宾语从句在复合句中做宾语，相当于名词He asked me which team couldwin the game.同位语从句放在名词之后(news,problem, idea, suggestion,advice, thought, hope, fact等) 表明其具体内容You have no idea how worriedwe are.The fact that he lied againgreatly surprised us.二、考点及考查频率1．宾语从句：①连接代词 (32/101 )②连接副词(11/101 ) ③连接词(2/101)2. 主语从句：①连接代词(14/101) ②连接词(1/101)3. 表语从句：①连接副词(6/101) ②连接代词 (3/101)4. 同位语从句：(16/101)5.wh-ever引导的名词性从句：(10/101)6.that用法(6/101)（1）宾语从句连接代词高三1.How much one enjoys h imself travelling depends largely on he goes with，whether his friends or relatives．A．what B．who C．how D．why2.

名词性从句详解名词性从句包括主语从句、表语从句、宾语从句、同位语从句。

其关联词有连接词that，if，whether；疑问代词who，what，which和疑问副词when，where，how，why等。

一.语法讲解1.主语从句主语从句在句中做主语。

它可以放在主句谓语动词之前，但多数情况由it作形式主语，而把主语从句放在主句之后。

例如：Who did that is known to all.It is interesting that you should like him.2.表语从句表语从句在句中作表语，位于主句中的系动词之后。

如：The question is who can complete the difficult task.表语从句不能用if引导，但可用as if引导。

例如：He looked as if he was going to cry．3.同位语从句同位语从句跟在名词后面，进一步说明该名词的具体内容。

引导同位语从句的名词主要有fact，news，promise，idea，truth等。

连接词用that（不用which），及连接副词how，when，where，why等。

例如：His delay is due to the fact that the car went wrong halfway．The news that our team has won the match is true.She asked the reason why there was a delay．4.宾语从句1.宾语从句在句中作及物动词或介词的宾语。

例如：We can learn what we did not know．He will talk to us about what he saw in the U.S.如果主句的谓语动词是及物动词make，find，see，hear等，则把宾语从句置于宾语补足语之后，用it作为形式宾语。

高考名词性从句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。

一、引导名词性从句的连接词名词性从句引导词的分类二.主语从句What he wants to tell us is not clear.Who will win the match is still unknown.Where the English evening will be held has not yet been announced.注意：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。

2、宾语从句(1)常见的可以接that从句作宾语的动词有see, say, know, imagine, discover, believe, tell, show, think, consider, be sure, be afraid等。

在可以接复合宾语的动词之后，如think, make, consider等，可以用it作形式宾语。

(2)That从句一般不能充当介词宾语，偶尔可作except, in 的宾语。

3、表语从句(that不可省略)4、同位语从句连词that引导同位语从句时，应在某些抽象名词之后，如：fact, hope, desire, thought, suggestion, idea, news, problem, possibility等，对前面的名词起补充说明的作用，that在从句中不担当任何成分，不能省略。

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。

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。
