名词性从句是独立的,而定语从句必须要依附先行词(相当于寄身虫)。

有时名词性从句可以转换成定语从句(必须加先行词)。

比如:What he said = The things that he said二、构成构成一个名词性从句就像是对一个陈述句进行特殊疑问句的提问,只不过不颠倒语序,如:He said something.What he said (名词性从句)What did he say? (特殊疑问句)三、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, however1.主语从句【例句】1.That prices will go up is certain.= It is certain that prices will go up.2.How you travel means the difference between success and failure.3.Whether we go by train or by boat makes no difference.4.Who will write the poem has not been decided yet.5.What surprised us is that he lost in the game.6.What he left us was a large sum of money.7.When he will be back depends on the weather.8.Where we live doesn’t matter.9.How the pyramids were built was still a mystery.10.Watever he did is right.11.Whoever comes will be welcome.12.Whichever you want is yours.【注意点】That引导的主语从句中,that不能省略。

高中英语名词性从句详细讲解

高中英语名词性从句详细讲解

名词性从句带有从句的复合句就是用连接词把主句和从句连接在一起。

高中英语中共有三大从句:形容词性从句(即定语从句);二、名词性从句;三、状语从句。

形容词性从句即定语从句,相当于一个形容词,作先行词的定语,用来修饰前面的名词或代词的。

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,名词性从句分为主语从句、表语从句、宾语从句和同位从句。

主语从句、表语从句、宾语从句只有在主句句子的成分残缺时才可以考虑使用这三大从句。

同位语则是对前面某一名词的展开,即对前一名词的具体说明,做进一步解释,两者是同等,并不是定语从句的修饰与被修饰关系。

名词性从句考得最多的是宾语从句,其次是主语从句,再次是表语从句,而同位语从句则很少考查。

名词性从句的连接词:1.从属连接词:that(无任何词义),whether/if(均表示“是否”表明从句内容的不确定性),as if /as though (均表示“好像”“似乎”)。

以上词在从句中均不充当任何成分,只起连接作用。

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

2.连接代词:what,who, whom, whose,which,whatever, whoever,whichever,whomever。

有词义,在从句中担任成分,如主语、表语、宾语、或定语。

从句一定要用陈述语序。

\3.连接副词:when,where,why,how, how many,how much,how often。

有词义,在从句中担任成分,作状语。

【注意】连接代词与连接副词既保留自己的疑问含义,又起连接作用,在从句中充当成分。

4.不可省略的连词:(1)介词后的连词;(2)引导主语从句和同位语从句的连词不可省略。

That she was chosen made us very happy.We heard the news that our team had won.(一)主语从句…第一部分:常规主语从句,即从句在复合句中充当一个主语。

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。

它们分为主语从句、表语从句、宾语从句和同位从句。

宾语从句作为复合句中的主句及物动词的宾语,也可以作为介词或某些形容词的宾语。

它不担任成分,只起连接作用。

连接词可以是从属连词、关系代词、关系副词。

从属连词包括that、whether、if;关系代词包括who、whom、whose、what、which;关系副词包括when、where、why、how。

这些词既担任成分,又起连接作用。

宾语从句的例子有:I think (that) you will like the pictures。

He has e what he wanted to be ten years ago。

I don’t know why Jane was late for school this morning。

The teacher is pleased with what she said。

I'm afraid that I can't go to the party.在宾语从句中,由that引导的从句可以省略,但如果从句是并列句时,第二个分句前的that不可省略。

另外,宾语从句中的时态要与主句呼应,如果主句动词是过去时态,从句则要用相应的过去时态。

如果从句表示的是客观真理、科学原理或自然现象,从句仍用现在时态。

如果主语谓语动词为think、consider、suppose、believe、expect、guess、imagine等,其后的宾语从句若含有否定意义,一般要把否定词转移到主句谓语上,从句谓语用肯定式。

XXX。

It is often said that traveling broadens the mind。

I XXX I was determined to carry out the plan。

I consider it XXX。

2023年高中英语语法讲义-名词性从句

2023年高中英语语法讲义-名词性从句

2023年高中英语语法讲义-名词性从句一、概说名词性从句,即指具有名词性质的从句,它包括主语从句、宾语从句、表语从句和同位语从句。

名词性从句是高中英语学习中的一个语法重点,也是历年高考重点考查的内容之一。

学习名词性从句主要应注意其引导词的用法与区别,从句的词序以及名词性从句与其他从句的区别。

二、主语从句1.主语从的引导词主语从句通常由连词that和whether、连接代词或连接副词以及关系代词型what引导What we need is money.我们需要的是钱。

What I want to know is this.我想知道的就是这一点。

Whether they would support us was a problem.他们是否会支持我们还是一个问题2.主语从向与形式主语it有时为了考虑句子平衡,通常在主语从句处使用形式主语i,而将真正的主语从句移至句末。

这分三种情况:(1)对于以连词thatgl导的主语从句,通常用形式主语代主语从句:It’s a pity that he didnt come.很遗憾他没来。

(2)对于以连接代词(副词)引导的主语从句,可以使用形式主语代主语从句,也可直接在句首使用主语从句:Whether they wouldsupport us was a problem.他们是否会支持我们还是一个问题。

It was a problem whether they would support us.他们是否会支持我们还是一个问题。

(3)对关系代词型what引导的主语从,通常不用形式主语,总是主语从句放在句首:What we need is money.我们需要的是钱。

What I want to know is this.我想知道的就是这一点。

(4)如果句子是疑问句,则必须用带形式主语it的结构:Is it true that he is the girl's father? 他是那女孩的父亲,是真的吗?How is it that you are late again? 你怎么又迟到了?3.连词that的省略问题引导主语从句的连词that有时可省,有时不能省,其原则是:若ha导的主语从句直接位于句首,则ha不能省略;若hat引导的主语从句位于句末,而在句首使用了形式主语it,则that则可以省略: That you didn’t go to the talk was a pity. 很遗憾你没去听报告。

高中名词性从句讲义

高中名词性从句讲义

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,名词性从句可分为主语从句、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 i f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、宾语从句、表语从句1)构成:关联词+简单句2)例如:Who is on duty hasn’t been decided.We haven’t decided who is on duty.The question is who is on duty.What he is doing is a question.I don’t know what he is doing.The question is what he is doing.How he gets so much money is still a question.I don’t know how he gets so much money.The question is how he gets so much money.3)从属连词that.(在句子中不充当成分,没有意义,只起连接作用)例如:The trouble is that he doesn’t know the answer.That he does n’t know the answer is still a trouble.He tells me that he doesn’t know the answer.4)从属连词whether(是否)例如:I doubt whether he will come or not.Whether he will come or not is still a doubt.The question is whether he will come.5)主语从句能用it作形式上的主语。

专题十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?】根据从句在句子中的功能分根据从句的性质分定语从句形容词性从句主语从句宾语从句名词性从句表语从句同位语从句状语从句副词性从句【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。

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。

名词性从句一.定义: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。

1. His words are true. What he said is true.2. The dog sensed something good. The dog sensed that there was something good nearby.3. These are his words. These are what he said.4. My Maths teacher, Mr He, is a kind person. The news that the plane had crashed made us sad.二.引导名词性从句的连接词连词:在从句中不充当成分,只起连接作用 that, 无实义whether, if 是否as if \ as though 似乎,好像连接代词:有词义,在句中担任主语,表语,定语或宾语。

what, 什么 who, 谁whom, 谁,作宾语 whose, 谁的 which, 哪一个whatever, whoever……也可以引导。

连接副词:有词义,在句中担任状语。

when ,什么时候 where, 什么地方 why, 为什么 how ,怎么样how many, how much, how often三.主语从句1. 作句子主语的从句叫主语从句。

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。

That he is late for school makes the teacher very angry. 他上学迟到让老师很生气。

2.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。

主语从句后的谓语动词一般用单数形式。

常用句型如下:(1) It + be + 名词 + that从句e.g. It is a pity that we won't be able to go to the south to spend our summer vacation.(2)It + be + 形容词 + that从句Eg. It is certain that he will win the match.It is very likely that they will hold a meeting.It is strange that the man should have stuck to his silly ideas.(3)It + be + 动词的过去分词 + that从句Eg. It is said that he has gone to shanghai.(=He is said to have gone to shanghai)It is suggested that the work (should) be done with great care.(4)It + 不及物动词 + that 从句Eg. It seems that he has seen the film.(=He seems to have seen the film)It happened that the two cheats were there. (=The two cheats happened to be there)注意:在主语从句中用来表示惊奇、不相信、惋惜、理应如此等语气时,谓语动词要用虚拟语气“(should) +do”,常用的句型有:It is necessary (important, natural, strange, etc.) that … It is suggested (requested, proposed, desired, etc.) that…3.主语从句的时态:不受主句的时态影响和限制。

(1)Whether we will go for an outing tomorrow remains unknown.(2)Who will be our monitor hasn't been decided yet.(3)Whatever you did is right.(4)Who the watch belongs to was lost is unknown.4. that 与 what 引导主语从句的区别what 有词义,在句中担任主语,表语,定语或宾语。

that 无词义,不作任何成分,只起连接作用 Eg. What has made him mad is not known yet. That she is still alive is a consolation.四.宾语从句1.定义:名词句用作宾语的从句叫宾语从句。

2.由连接词that引导宾语从句时,that在句中不担任任何成分,在口语或非正式的文体中常被省去,但如从句是并列句时,第二个分句前的that不可省。

例如:He has told me that he will go to Shanghai tomorrow. 他已经告诉我他明天要去上海。

We all think (that ) she is working hard and that she will surely go to a very good university. 我们都认为她学习非常努力,一定能进一个非常好的大学。

3.在demand、order、suggest、decide、insist, desire, request, command等表示要求、命令、建议、决定等意义的动词后,宾语从句常用“(should)+ 动词原形”。

例如:I insist that she (should) do her work alone. 我坚持要她自己工作。

The commander ordered that troops (should) set off at once. 司令员命令部队马上出发。

4. 可运用形式宾语it代替的宾语从句①动词find, feel, consider, make, believe等后面有宾语补足语的时候,则需要用it做形式宾语而将that宾语从句后置.I think it necessary that we take plenty of water every day .我认为每天多喝水是有必要的.We all find it important that we (should) make a quick decision about this mater. 我们都认为对这件事马上做出决定很重要.②有些动词带宾语从句时需要在宾语与从句前加it 这类动词主要有:hate, take , owe, have, see to.Eg. I hate it when they talk with their mouths full of food.我讨厌他们满嘴食物时说话.He took it for granted that his girlfriend would come back again.他想当然的认为女朋友会再回来。

③若宾语从句是wh-类,则不可用it代替We all consider what you said to be unbelievable.我们都认为你所说的是不可信的.We discovered what we had learned to be valuable.我们发现我们所学到的东西都是有用的.5.用who,whom, which, whose, what, when, where, why, how, whoever, whatever, whichever 等关联词引导的宾语从句相当于特殊疑问句,应注意句子语序要用陈述语序。

例如:I want to know what he has told you. 我想知道他告诉了你什么。

She always thinks of how she can work well. 她总是在想怎样能把工作做好。

6.用whether或if引导的宾语从句,其主语和谓语的顺序也不能颠倒,仍保持陈述句语序。

此外,whether与if 在作“是否”的意思讲时在下列情况下一般只能用whether,不用if:a. 引导主语从句并在句首时;b. 引导表语从句时;c . 引导从句作介词宾语时;d. 从句后有“or not”时;e. 后接动词不定式时。

Eg. Whether there is life on the moon is an interesting question. 月球上有没有生命是个有趣的问题。

I wonder whether he will come or not. 我想知道他来还是不来。

7.注意宾语从句中的时态呼应,当主句动词是现在时,从句根据自身的句子情况,而使用不同时态。

例如:I know (that) he will study English next year. (从句用一般将来时)当主句动词是过去时态(could, would除外),从句则要用相应的过去时态,如一般过去时,过去进行时,过去将来时等;当从句表示的是客观真理,科学原理,自然现象,则从句仍用现在时态。

例如: He says he studies English every day.The teacher told us that Tom had left for America.8. think, believe, imagine, suppose等等动词引起的否定性宾语从句中,要把上述主句中的动词变为否定式。

即将从句中的否定形式移到主句中。

例如:We don’t think you are here. 我们认为你不在这。

I don’t believe he will do so. 我相信他不会这样做。

9.感叹句在宾语从句中的运用You can’t imagine ______ when they received these nice Christmas presents. A. how they were e xcited B. how excited they were C. how excited were they D. they were how excited五.表语从句1.定义:在句中作表语的从句叫表语从句。
