高中英语语法：名词性从句知识汇总
高中英语语法：名词性从句知识汇总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。
当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。
一、引导名词性从句的关联词引导名词性从句的关联词大致相同，它们分别是：连词：that, whether, if；关系代词：who, what, which , whom, whose, whatever, whoever, whomever, whichever；关系副词：when, where, how, why, however, whenever, wherever。
引导从句时一般不用逗号和主句分开。
连词that在从句中不作成分，不含疑问意义；而wh-连词在从句中作成分，且含有疑问意义；或what/where从句相当于一个名词后加一个定语从句。
It worried her a bit that her hair was turning grey.她的头发在变白令她有点担忧。
（that在从句中只起引导词作用，不作成分）What caused the accident is still a complete mystery.事故发生的原因仍然是个不解之谜。
（What在从句中作主语）2、that与whether引导名词性从句的区别。
（1）动词doubt表示“怀疑、不知道”解时，肯定句接whether引导的宾语从句；否定句don’t doubt和疑问句Do you doubt要接that引导的从句。
I don’t doubt that he will come soon.我不怀疑他不久会来。
（此处不用whether）Can you doubt that he will win?你怀疑他会赢吗？（此处不用whether）比较：doubt表示“不信”解时，表示强烈的不相信时，在陈述句中可接that从句。

定义：在复合句中充当宾语功能的句子叫宾语从句We can learn what we didn't know。
We find it necessary that we （should）practice English every day.★某些作表语的形容词，如sure，happy, glad，certain等之后可带宾语从句I am glad that you can come and help me.:①wish/would rather后的宾语从句中要用虚拟语气。
I wish I had finished my homework yesterday。
I’d rather you had been there yesterday②在表示建议,命令, 请求的词后面的宾语从句当中用should + V，可以省略His pale face suggested that he was ill so I suggested that he should goto see the doctor.He insisted that he was innocent and insisted that he should be set free.③注意it作形式宾语的结构We all thought it a pity that we had missed the lesson。
I took it for granted that they were not coming.④ that一般不接介词宾语，偶尔可作except， in的宾语；其它介词后面需用it作形式宾语He differs from his roommates in that he devoted his spare time toreading.He knows nothing about Jim except that he is from London。

高中英语名词性从句复习
高中英语名词性从句复习名词性从句就是在句子中起名词作用的句子。
名词性从句的功能相当于名词词组, 它在复合句中能够担任主语、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。
名词性从句有三大要素：引导词、语序和时态。
名词性从句的引导词也就是引导名词性从句的关联词。
这些引导词可分为三类,一是that 类，二是if / whether类，三是疑问词类。
既然是引导词，所以这些词就总是位于名词性从句的最前面。
名词性从句的语序，是指名词性从句都必须与陈述句语序相同，即“主语＋谓语”。
事实上，任何一种从句，其语序都必须与陈述句的语序相同。
关于名词性从句的时态，若主句的谓语动词是一般现在时时，宾语从句的谓语动词可根据情况使用各种时态；若主句的谓语动词是一般过去时，宾语从句若不是一个客观事实或真理，其谓语动词也必须用某种过去时态。
名词性从句中连接词的运用：名词性从句中的连接词有连词that / whether / if，连接代词what / who/ which / whose / whatever / whoever / whomever / whichever，连接副词where / when / why / how / wherever /whenever。
一、that的用法：①主语从句、表语从句、同位语从句中用that但不能省略。
如：That they are good at English is known to us all.The problem is that we don’t have enough money.She expressed the hope that they would come to China one day.②宾语从句中的连接词that有时可省有时又不可省，在以下几种情况中that不能省略：当that从句和主句谓语动词之间有插入词语或者从句主语之间有插入语时，that不可省略；当that 从句与另一名词性从句并列作宾语时，that不能省；当that作介词宾语时，that不可省掉。

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。

(完整版)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。

例如：It is not important who will go. 谁去,这不重要。
It is still unknown which team will win the match. 到底谁赢呢,形势尚不明朗。

高中英语名词性从句知识点整理
高中英语名词性从句知识点整理在高中英语学习中，名词性从句是一种十分重要的语法结构，也是很多学生需要掌握的技能。
名词性从句指的是在复合句中充当名词的句子，其中包括关系从句、宾语从句、主语从句和表语从句。
在本文中，我们将整理名词性从句的四种类型及其相应的知识点。
1. 关系从句关系从句是名词性从句中相对较为简单的一种，主要由一个关系代词或关系副词引导。
关系代词包括who、whom、whose、that和which，而关系副词则包括when、where和why。
关系从句常用于修饰先行词，充当定语的作用。
1.1 who和whomwho和whom都可以指人，但who是主格代词，而whom则是宾格代词。
who用于作主语，而whom常用于作宾语。
例如：•I saw a man who was running.（我看到一个正在跑步的人。
）•The man whom I met yesterday is my teacher.（我昨天遇到的那个人是我的老师。
）需要注意的是，在口语中，who和whom的使用通常会和正式的语法规则有所差别。
1.2 whosewhose是一个关系代词，用于表示所有关系。
它的后面必须跟名词。
例如：•The girl whose bag was stolen was crying.（那个被偷了包的女孩在哭。
）1.3 that和whichthat和which都可以用于引导关系从句，但它们用法上有所不同。
基本规则是：当先行词为非限定性或逗号后面的词时，应使用which；当先行词为限定性或没有逗号时，可以使用that或which。
但在口语中它们通常是可以互换使用的，需要注意的是，在非正式的语境中，that更常用。
1.4 关系副词关系副词主要有when、where和why三个，它们分别用于表示时间、地点和原因。
例如：•This is the hotel where I stayed last time.（这就是我上次住的那个旅馆。
【高中英语】高中语法讲解之名词性从句
【高中英语】高中语法讲解之名词性从句一、引导名词性从句的连接词1.连接代词：who，who，who，what，who，what，who，what，它具有词义，在一个从句中充当一个成分，如主语、谓语、宾语、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：指没有意义且不作为从句中的一个成分的、是否、如果、asif。
有时可以省略；如果（是否），asif有一个词的意思，但它不作为一个从句中的一个元素。
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），asif（好像）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asif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.谁去并不重要。
2.用it作形式主语，主语从句放在句末。
3.在指导主题条款时不能忽略这一点。
e.g.thathesuddenlyfellilllastweekmadeussurprised.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、问题是谁能到这里。
2.引导表语从句的连接词that有时可省去。
四、宾语从句1.宾语从句在复合句中作宾语。
引导宾语从句的连词that一般可省略。
e、我希望一切都好。
2.介词之后的宾语从句，不可用which或if连接，要分别用what或whether.e、我不知道你是否完成了工作……i’minterestedinwhatyou‘vesaid.3.是否和如果都可以产生宾语从句，宾语从句通常是可互换的。
但以下情况不能互换。
（1）宾语从句是否定句时，只用if，不用whether.e、 g.Iwonderifit不训练。
（2）用if会引起误解，就要用whether.e、请告诉我你想不想去。

语法复习三：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。
引导宾语从句的连词that一般可省略。
e.g. I hope (that) everything is all right.2、介词之后的宾语从句，不可用which或if连接，要分别用what或 whether。
e.g. I’m interested in whether you’ve finishe d the work..I’m interested in what you’ve said.3、whether与if都可以引导宾语从句，常可互换。
但下面情况不能互换。
①宾语从句是否定句时，只用if，不用whether。
e.g. I wonder if it doesn’t rain.②用if 会引起误解，就要用whether。
e.g. Please let me know whether you want to go.（此句如果把whether改成if，容易当成条件句理解）③宾语从句中的whether 与or not直接连用，就不能换成if；不直接连用，可换。
e.g. I don’t know whether or not the report is true.I don’t know whether/ if the report is true or not.④介词后的宾语从句要用whether引导。
whether 可与不定式连用。
whether 也可引导主语从句、表语从句、同位语从句，还可引导让步状语从句，以上均不能换成if。
但引导条件从句时，只能用if，而不能用whether。
e.g. It depends on whether we have enough time.They don’t know whether to go there.Please come to see me if you have time.（五）同位语从句同位语从句在句中作某一名词的同位语，一般位于该名词（如：news, fact, idea, suggestion, promise等）之后，说明该名词的具体内容。
e.g. I have no idea when he will be back.The fact that he had not said anything surprised everybody.练习：名词性从句一、判断下列各句哪句含有名词性从句，并指出是什么从句：1. China is no longer what it used to be.2.
