(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。

高考教学英语语法知识总结点总结:名词性从句
高考英语语法知识点:名词性从句高考英语频道为大家提供高考英语语法知识点:名词性从句,赶紧看看你掌握了没?更多高考资讯请关注我们网站的更新!高考英语语法知识点:名词性从句1、什么叫名词性从句从命名法的角度,名词性从句拆开来就是名词性的一个从句。
从句,顾名思义它是附属的成分,它是附属于主句存在的,不能单独存在,就类似于一个家里面一个大人带着一个小孩才能去玩,不能这个小孩自己单独去玩。
名词性顾名思义这个从句它是一个名词性的,就相当于这个从句它就是个名词,那么它在主句中要充当名词能充当的成分。
主句中名词的成分可以是主语、宾语、表语、同位语,所以名词性从句就是用一个句子在主句中充当主语或者宾语或者同位语或者表语的这样的成分,可以简单地记成名词性从句,包括主宾表同四大从句,这个就是名词性从句的本质和功能。
2、名词性从句的难点对名词性从句本质的理解和句子结构的划分名词性从句是镶嵌在主句中的,它不像定语从句,定语从句是主句穿了一个马甲,比方主谓宾,然后在主语后面加一个定语从句来修饰这个主语,而名词性从句不一样,它是直接用这个从句去做主句的主语或者做主句的宾语,所以在理解的时候名词性从句是没有方法拿掉的,一定要和主句一起来理解,那么这就是在划分名词性从句结构,分析句子结构的时候的一个难点。
具体的引导词的用法没有方法直接把两个句子合在一起,就不得不说一个句子是从句,这样就一定要有标记词来告诉我们,这个句子是一个从句。
举个例子:“我知道他迟到了。
〞在这句话中,“我〞是主语,“知道〞是谓语。
“他迟到了〞这件事作为宾语。
所以“他迟到了〞就是作为宾语从句。
在英语中不能直接说“我知道他迟到了。
〞而是说“我知道that他迟到了。
〞因为这个that的存在就把“他迟到了〞这件事变成了一个名词性从句的成分,整个句子就相当于是一个名词作主句的宾语。
那么主语从句、表语从句和同位语从句也是一样的道理,需要在这个从句前面加一个引导词来说明这个从句的身份,给他戴个帽子。

名词性从句梳理
名词性从句梳理一、名词性从句梳理基础知识回顾知识讲解主语从句:做主语用的名词性从句,因其在复合句中做主语,又称主语从句,引导主语从句的有连词that ,whether,连接代词who ,what ,which,连接副词when,where,how,why等。
1)从属连词:that,whether等.that 引导主语从句只起引导作用,本身无实际意义,在主语从句中不充当任何成分,但不能省略。
That he will win is certain.他肯定会赢。
Whether he’ll come here isn’t clear. 他是否会来这里还不清楚。
注意: 由that 引导的主语从句有时为了使句子结构平衡, 避免“头重脚轻”, 常用it 作形式主语, 而把从句放在后面。
例如:That he will refuse this piece of advice is impossible.It is impossible that he will refuse this piece of advice.it为形式主语2. That they should like each other is natural.It is natural that they should like each other.这样就构成了下面一些常用句型:1) It is + n. +从句It is a pity/shame that... 遗憾的是……It is a surprise that…令人惊奇的是…It is a fact that……是事实It is common knowledge that……是常识2) It is + adj. +从句It’s certain that…肯定…It is possible that... 很可能……I. 名词性从句的引导词:1.连接词:that、if、whether不作成分无意义“是否”2. 连接代词:who、whom 、whose、what、which 、whoever, whatever作主/宾/表3. 连接副词:when、where、why、how作状语1. The suit fitted him well except ________ the color was a little brighter.2. Eat whichever cake you like and leave the others for _______ comes in late.3. I told him _______ I was surprised at his attitude towards his study.It is known to all that we have been debating on the problem of pollution for decades.8. 这种植物怎样腐烂,为什么会腐烂仍然是个未知数。

名词性从句第一节主语从句引导主语从句的连接词有:that, whether, who, which, what, when, where, how, why等That she was invited to the ball made her very happy.Whether he will come to the ball has nothing to do with me.Whoever wants to see the film may get a ticket free.Which team will win the match is still unknown.What interests you doesn’t interest him.Where they had stayed was still unknown.When they will have a meeting hasn’t been decided.注意:1从句作主语谓语动词用第三人称单数形式。
Who will go is not important.2为了调节句子平衡,常用it作形式主语。
It i s a pity that he didn’t come yesterday.It’s necessary that every League member (should) take the lead and work well.It’s suggested that a modern hotel (should) be put up at the foot of the hill.3陈述句部分的主语是从句时,其反意疑问句部分的主语用it.How he became a scientist is known to us all, isn’t it?第二节宾语从句作动词、介词或形容词宾语的从句。
以连词 that who whom whose what 等引导,在句子中充当宾语I think (that) you will like the pictures.I feel it important that they finish their own task in time.They are worrying about whether they can get there in time.You can write about whatever topic you can think of.一宾语从句三原则:语序;时态;引导词。
1.语序:宾语从句用陈述句语序。
I wonder what he is writing to me about但是:what’s the matter/wrong (with)……语序不变.The owner came up to see what was the matter with me/what was wrong with me2.时态:宾语从句谓语动词的时态与主句谓语动词的时态保持一致。
(1).如果主句的谓语动词是一般现在时或一般将来时,宾语从句用它本身的时态。
I hear he will come back in an hour.(2).如果主句的谓语动词是一般过去时,宾语从句则用相应的过去时态。
She said that he had never been to the Great Wall.(3).如果宾语从句的内容是客观真理时,宾语从句仍然用一般现在时。
The teacher told us that the earth goes around the sun. / light travels faster than sound.3.引导词:(1)由that引导(2)由if/whether引导(3)由特殊疑问词引导二 it在宾语从句中的应用:1. vt.+it+adj./n.+that-clause 或wh-clause。
She has made it clear that she will have nothing to do with him.2.i)在主谓宾结构中,有一些习惯上不以that-clause或 wh-clause从句直接作宾语的动词,如果要接宾语从句,往往需要在从句前加上形式宾语it. The newspapers have it that some Japanese firms have gone bankrupt.报纸说有几家日本公司已破产这类动词还有:have(表明,坚持说),take(认为),hide(隐瞒),love ,like,dislike, hate, enjoy ii) 在主谓宾结构中, 如果谓语动词是短语动词,即动词+介词,一般不能that接从句。
如果接从句,必须加上形式宾语it. I will answer for it that Lao Ma will accomplish the task.我担保老马能完成这项任务Look to it that you make no more similar mistakes.注意今后你不再犯类似的错误了I am counting on it that you will come.我期待着你的到来这类动词还有:depend on, see to etc.iii)某些固定搭配之后如果接that宾语从句,也必须使用作形式宾语it.We owe it to you that there wasn’t a serious accident.这次事故没造成严重的后果全靠你I didn’t send you an invitation, as I took it for granted that you would be coming.因为我认为你当然会来,所以没有给你发请柬三1 否定的转移当主句的谓语动词是think, believe, suppose, expect, imagine等表示看法的动词时,宾语从句中谓语动词的否定式,习惯上前移到主句的谓语动词上.I don’t think that he will be back until nine.2 复杂疑问句/双重疑问句特殊疑问词+do you think/ believe/ suppose/imagine etc+其它部分(陈述句语序)?Who do you guess that girl in red is?Who do you imagine will speak at the meeting tomorrow?3 ----Will they be ready tomorrow?----Yes, I think so. (Yes, I think that they will be ready tomorrow)so 用来替代某一些动词(think, believe, suppose, imagine, hope etc) 后面的that从句.----Will they attend the meeting next month? ----No, I don’t believe so (I believe not)在替代否定概念,既可以用so,也可以用not.但是:在hope和be afraid后在替代否定概念只能是not,不能是so.----Do you think we’ll have bad weather? ----I hope not.----Have you got a work permit? ----I’m afraid not.第三节表语从句含有表语从句的复合句,其主句的主语常常用fact, idea, opinion, problem, question, reason, result或者由what引起的主语从句。
引导表语从句连接代词或者连接副词除常用that以外,who, which, what, whether, when, where, why, how, because, as, as if/as though等。
如:The chance is that one smoker in four will die from smoking.What we want to know is whether your products came up to the standardShenzhen is no longer what it used to be.This is how they overcame the difficulties.It sounds as if/though somebody was knocking at the door.注意:先说结果,后说原因,用This/That is because…先说原因,后说结果,用That/This is why…当主语是reason时,引导表语从句的连接词只能用that ,如He is absent. This is because he is ill.// He is ill. That is why he is absent.// The reason why he is absent is that he is ill. 第四节同位语从句1 先行词与连接代词或者连接副词的选择常见的可以跟同位语从句的名词有:fact, news, hope, belief, truth, message, word, idea, doubt, question, problem, reason, order, suggestion, 等。
引导同位语从句连接代词或者连接副词除常用that以外,who, which, what, whether, when, where, why, how等。
如:I have no idea whether he can manage to do that himself.I have no idea where he spent the night.The question how the students could improve their spoken English is very important2 同位语从句与定语从句的区别He made a decision that surprised all of us.He has made a decision that he will set up a new factory.同位语从句说明名词的具体内容。
that和whether只起连接作用,不充当任何成分,不能省略,也不能用which或if代替;其他的连接词在同位于从句中作句子成分,但不是指代前面的名词,而是有自身疑问意思。
