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。
名词性从句知识点总结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。
一.主语从句主语从句是在复合句中充当主语的从句,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. 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。
被强调部分指人时也可用who/whom。
例如:a) It is a pity that you didn’t go to see the film. 你不去看那场电影真可惜。
b) It doesn’t interest me whether you succeed or not.我对你成功与否不感兴趣。
c) It is in the morning that the murder took place.谋杀案是在早上发生的。
(强调句型)d) It is John that broke the window.是John打碎的窗户。
(强调句型)2. 用it 作形式主语的结构(1) It is +名词+从句It is a fact that …事实是…It is an honor that …非常荣幸It is common knowledge that …是常识(2) It is +形容词+从句It is natural that…很自然…It is strange that…奇怪的是…(3) It is +不及物动词+从句It seems that…似乎…It happened that…碰巧…It appears that…似乎…(4) It +过去分词+从句It is reported that…据报道…It has been proved that…已证实…It is said that…据说…3. 主语从句不可位于句首的五种情况:(1)if 引导的主语从句不可居于复合句句首。
名词性从句名词性从句指在复合句中起名词作用的从句,它在句子中可作主语、宾语、表语或同位语。
名词性从句既是中学英语教学的重点,也是高考考查的热点。
一、名词性从句的分类名词性从句包括主语从句、宾语从句、表语从句和同位语从句。
其连接词有that, if, whether;连接代词who, what, which;连接副词when, where, how, why等。
考查热点一:对主语从句的考查主语从句在复合句中充当主语,它可以放在主句谓语动词之前。
但为了保持句子平衡,多数情况下可用it作形式主语,而把主语从句置于句尾。
考查热点二:对宾语从句的考查宾语从句在句子中作及物动词或介词的宾语。
如果主句的谓语动词是及物动make, find, see, think等,则把宾语从句置于宾语补足语之后,用it作形式宾语。
另外,某些作表语的形容词,如sure, happy, glad, certain 等之后也可以带宾语从句。
考查热点三:对表语从句的考查表语从句在句子中作表语,位于主句中的系动词之后。
一、什么是表语(predicative)在形式上,位于系动词后的就是表语。
从含义上讲,表语是回答主语“是什么”或“怎么样”的语法成分。
即是指“是”字句“是”字后面的成分。
表语就是起表述作用的句子成分。
它修饰的是主语。
表语是用来说明主语的身份、性质、品性、特征和状态的。
表语须和连系动词一起构成句子的复合谓语。
表语常由名词、形容词、副词、介词短语、不定式、动词的-ing、动词的-ed、从句来充当,它常位于连系动词(be, become, appear, seem等)之后。
Albert Einstein was a famous professor of physics.二、不定式、动名词与分词作表语的区别不定式和动名词作表语相当于一个名词作表语,含义是回答主语“是什么”;分词作表语相当于形容词作表语,含义是回答主语“怎么样”。
考点七十名词性从句1.名词性从句必须采用陈述语序。
①I want to know what he has told you.我想知道他告诉了你什么。
②She always thinks of how she can work well.她总是在想怎样能把工作做好。
2.it充当形式主语或宾语:在名词性从句中,为了使句子保持平衡,常用先行词it来代替主语从句或宾语从句,而把主语从句或宾语从句放到后面,尤其是连词that引导的主语从句常用于此句式中。
①It 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。
②I find it strange that she doesn’t want to travel.她竟不想旅游,我觉得很奇怪。
3.在名词性从句中that与what的差异:what在从句中要充当某个成分(主语、宾语或表语),在任何情况下都不能省略,表示"(=the thing or things that...; whatever)……的事物;无论什么;凡是……的事物"。
that本身没有词汇意义,在从句中不充当任何成分,在口语和非正式文件中,宾语从句中的that常常省略。
①What you have done might do harm to others.你所做的事或许对别人有害处。
②I spent what little time I had with my family.我仅有的一点儿时间都和家人在一起度过了。
③No one knows what will happen next.谁也不知道下一步有什么事。
④I think(that) you will like the stamps.我认为你会喜欢这些邮票的。
4.whether和if的差异:(1)引导主语从句、表语从句或同位语从句,只能采用whether。
☞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。

➢His father is concerned about whether he will be kicked out of school.♥Attention♥if或whether引导的宾语从句时,虽具有疑问意义,但从句语序应用陈述句语序。
一、名词性从句的八点注意(一)注意不可多that连接代词who, whom, which,whose,what;连接副词how, why, when,where; 连接词if, whether;所有这些词前,不可再用that。
例如:He doesn't know that when they arrived here。
(去掉that)(二) 注意不可少that引导名词性从句的that在句子中无具体意思,但在下列情况下,that不可省略:1。
宾语从句被分隔时;2。
宾语从句不止一个时;3. 引导主语从句、表语从句或同位语从句时.例如下列句子中不可省略that:I don’t doubt, in any case,he keeps his word.(应在he前加上that)Everyone could see what was happening and poor Tom was nearly frightened。
(应在and后加上that)The earth goes round the sun was not widely accepted at that time。
(应在句首加上That)The problem is fuels like coal and oil cause a lot of pollution。
(应在is 后加上that)We heard the news our team had won。
(应在news后加上that)(三)引导词that的省略1.引导宾语从句时,that可以省略;但引导主语从句、表语从句和同位从句时,that通常不省略.例如:--Now we all know (that)capitalists brought in large quantities of wealth by taking possession of the surplus value--I first heard the story from my neighbor that the head of the county was arrested.2。
名词性从句(一)围绕名词性从句的连接词1、连接代词:w h o,w h o s e,w h o m,w h a t,w h i c h。
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:w h e n,w h e r e,w h y,h o w。
有词义,在从句中担任成分,作状语。
3、连接词:t h a t,w h e t h e r,i f,a s i f。
t h a t无词义,在从句中不担任成分,有时可省略;i f(w h e t h e r),a s i f虽有词义,但在从句中不担任成分。
注重:1、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w h e t h e r和i f(是否),a s i f(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,w h e t h e r、i f和a s i f都用不上时,才用t h a t 作连接词(t h a t本身无任何含义)。
2、不可省略的连词:(1)介词后的连词(2)围绕主语从句和同位语从句的连词不可省略。
T h a t s h e w a s c h o s e n m a d e u s v e r y h a p p y.W e h e a r d t h e n e w s t h a t o u r t e a m h a d w o n.(二)主语从句1、主语从句在复合句作主语。
e.g.W h o w i l l g o i s n o t i m p o r t a n t.2、用i t作形式主语,主语从句放在句末。
e.g.I t d o e s n’t m a t t e r s o m u c h w h e t h e r y o u w i l l c o m e o r n o t.主要句型有:(1)I t+b e+形容词+t h a t从句。

2._____ is known to us all is that China has launched Shenzhou VII spaceship, ____ made the country's first spacewalk successful.A. That; whatB. What; whichC. It; whichD. As; that【答案】 B【解析】【分析】句意:众所周知,中国已经发射了神州7号宇宙飞船,这是中国首次成功的太空行走。

故选B。
【点评】考查名词性从句和定语从句,本题涉及主语从句和非限制性定语从句的应用。
3.___ surprised me most was ____the girl passed the driver test.A. That; thatB. What; howC. What; thatD. That; why【答案】 C【解析】【分析】句意:最让我吃惊的是那个女孩通过了驾驶考试。
___ surprised me most是一个主语从句,从句中缺少主语,故填what;____the girl passed the driver test 是一个表语从句,句中不缺少成分,故填that。
因此选C。
高中英语名词性从句知识点(含练习)基础回顾1.表语:表语用来说明主语的身份、性质、品性、特征和状态的,表语常由名词、形容词、副词、介词短语、动词的-ing、不定式、从句来充当,它常位于系动词(be, become, appear, seem,look,sound,feel,get,smell等词)之后。
如:Her job is selling computers. 此句表语为selling computers如果句子的表语也是由一个句子充当的,那么这个充当表语的句子就叫做表语从句。
2.同位语:一个名词(或其它形式)对另一个名词或代词进行解释或补充说明,这个名词(或其它形式)就是同位语。
如Mr. Smith,our new teacher,is very kind to us. 我们的新老师史密斯先生对我们很好。
Mr.Smith是主语our new teacher的同位语,指同一人。
同位语从句I heard the news that our team had won.我听到了我们队获胜的消息。
that our team had won 解释news的具体内容,是同位语正文一、定义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。
That he finished writing the composition in such a short time surprised us all他在很短的时间内写完作文让我们都很惊讶 (主语从句)The trouble is that she has lost his address. 麻烦的是她把他的地址搞丢了。
(表语从句)They have no idea at all where he has gone. 他们不知道他去什么地方了。
(同位语从句)Do you remember how he came? 你记得他怎么来的么?(宾语从句)二、语序名词性从句要采用陈述句语序。
