高中英语名词性从句用法
高中英语名词性从句用法从句是相对于主句而言的,即它是从属于某一个主句，而不能单独作一个句子。
在英语中，主要有三大从句，即名词性从句（包括主语从句,宾语从句,表语从句,同位语从句）、形容词性从句（即定语从句）、副词性从句（即状语从句,包括时间、条件、结果、目的、原因、让步、地点、方式等）。
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。
引导名词性从句的连接词可分为三类：（1）从属连接：that，whether，if（不充当从句的任何成分）（2）连接代词：what，whatever，who，whoever，whom，whose，which.（3）连接副词：when，where，how，why名词性从句知识点汇总1、名词性从句的分类名词性从句，包括四种从句，即主语从句、宾语从句、表语从句、同位语从句。
因为主语、宾语、表语、同位语这四种成分均可以由名词构成，所以这四种从句在主句中都充当了名词的作用，故将这四种从句统称为名词性从句。
如：1.That she will help me made us happy.（主语从句）2.I can understand what he said.（宾语从句）3.This is where I was born.（表语从句）4.The fact that a heavy earthquake happened made me crazy.（同位語从句）2、名词性从句的连接词分类1.that（无含义，不充当成分）2.whether，if（有“是否”的含义，但不充当成分）3.连接代词：what，whatever，who，whoever，whom，whomever，whose，which，whichever.（在从句中做主语、宾语、表语和定语）连接副词：when，whenever，where，wherever，how，however，why （在从句中做状语）4. as if，as though，because（不充当成分，在名词性从句中只引导表语从句）3、连接词that 在名词性从句中可以省略的三种情况1.it 做形式主语，that引导主语从句时It is said (that) he has been studying abroad.据说他一直在国外学习。

名词性从句易混点辨析
Whether he agrees or not, I shall do that.不管他同意与否,我都要那样做。
(7)用于不定式之前时。如:
I’m not sure whether to stay or leave.我不知是留还是去。
(8)直接与or not连用时。如:
1. Could you speak to is in charge of International Sales, please.
A. anyoneB. someone
C. whoeverD. no matter who
2. You’d better give the task to you think can succeed in carrying it out ahead of time.
注意:此题不能选择B,因为of后的宾语从句缺少主语而不是宾语,故用主格whoever,即anyone who。
四、no matter + what / who...和whatever / whoever...
当引导让步状语从句时,两者相同,可以互换,但当引导名词性从句(主语从句,宾语从句,表语从句和同位语从句)时则只能用whatever (whoever, whichever, whenever, etc)。
②He did what he could to help her.他尽全力来帮她。(what引导宾语从句,并在从句中做省略了的do的宾语)
③The boy isn’t what he used to be.这孩子不再是过去的样子了。(what引导表语从句,并在从句中做be的表语)
④I have no idea what has happened to her.我不知道她发生了什么事。(what引导同位语从句,并在从句中做主语)

知识点1基本用法引导词类别常见引导词作用连接代词what, which, who, whose, whom,whatever, whichever, whoever, whomever有词义，在从句中担任主语、表语、宾语、或定语等成分连接副词how, when, where, why, however,whenever, wherever有词义，在从句中担任状语成分从属连词that, whether, if 除that外均有词义，在从句中不担任成分，只起连接作用知识点2 主语从句1. 引导词在复合句中充当主句主语的从句叫作主语从句。

名词性从句易混知识归纳从句易混点归纳(名词性从句易混点)从句在英语学习过程中占据极其重要的位置,各从句中的知识之间、各从句之间存在着很多易混点,同学们经常为一些易混点所困扰,现将各从句中的知识之间、各从句之间的易混点做以归纳、总结。
下面我们先看名词性从句的易混点。
我主要从whether与if、that在名词性从句中是否省略、同位语从句与定语从句的区别、reason 后面的名词性从句、what引导的一种独特的名词性从句、check、make sure后面的宾语从句、what、whatever、who、whoever等引导的名词性从句几个方面进行说明、讲解,当然还有其他方面的易混点知识,这里就不进行一一叙述了。
易混点一whether与if二者都可以作“是否”讲,能引导名词性从句,都不能省略。
1.在及物动词后引导宾语从句时可以互换;注意:在某些动词后(如:discuss)只能接whether,不能跟if。
如:We discussed whether we should close the shop.2.引导主语从句、表语从句、同位语从句时都用whether,不用if。
如:The question whether he should come himself or send another man hasn’t been decided. Whether he will win is all the same to me.The question is whether you can go there yourself.如果用形式主语,if和whether都可以It is unknown whether\if she is ill.3.如果whether后紧跟or not,不用换做if;若whether与or not分开使用,则可以换作if。
如:I wonder whether or not he has arrived at the destination.I don’t know whether\if I can come or not.4.若宾语从句为否定结构,则多用if,而不用whether。
如:I don’t care if he doesn’t show up.(在乎,炫耀)5.在介词后引导宾语从句或与带to的动词不定式结合而构成不定式的复合结构时,只能用whether,而不用if。
如:I haven’t settled the question of whether I will go back home.She doesn’t know whether to get married now or wait.易混点二that在名词性从句是否省略that用来引导宾语从句、表语从句、主语从句、同位语从句这四类名词性从句。
在句子中that有时可以省略,有时不省略,有时两者皆可。
1.宾语从句中的that在口语中常省略,但在下列情况中,that应当保留。
(1)当主、从句之间有时间等状语时,that不能省略,否则会产生歧义。
He said last night that he did some reading.He said last night he did some reading.其含义有两个:他昨晚说他看了点儿书。
或他说他昨晚看了点儿书。
(2)主、从句之间有插入语时同样不可省去that。
如:I don’t doubt,in a ny case,that we will win the match.(无论如何,我都不怀疑我们会赢那场比赛)。
(3)引导两个或两个以上的宾语从句时,第二个或第二个以上的宾语从句中的that则不易省略。
如:She said Lesson 82 was very important and that she should learn it well.(若省略,后一从句则可能与上句she said并列)Everybody could see what was happening and that poor Rose was really frightened.(并列宾语从句。
省去that,则变为并列句。
)(3)如果宾语从句中含有主从复合句,that一般不宜省略。
如:They promised me that if I worked hard from then on,they would buy me a computer.(4)宾语从句提前时,that一般不省略。
如:That Bob was really frightened,I can’t believe.(5)简短回答中的宾语从句,that不宜省略。
如:What do you assume from his attitude?(你从他的态度中猜测到什么了?)That he was frightened.(6)当it作形式宾语代替that引导的宾语从句时,一般保留that。
如:I found it quite a surprise that everybody in that city has a car.2.引导主语从句的that一般不可省略,但若用it作形式主语,that则可省略。
That the earth moves around the sun is known to all.It is known to all (that)the earth moves around the sun.3.引导表语从句的that一般不省略。
如:The reason why he studies well is that he is always hardworking.4.引导同位语从句的that(尤其是说明主语的同位语)一般不可省略。
如:The news that our team had won the match excited everyone.I don’t agree to the suggestion that we give up the plan.易混点三同位语从句与定语从句的区别1.that引导的从句,是定语从句还是同位语从句,我们我们采用“试加法”,来判断。
The fact that he had not said anything surprised everybody.This is the fact that you must know clearly.2.when、where、why引导的从句引导定语从句时,其意义与先行词有关,与先行词的意义基本相同,没有疑问意义;但引导同位语从句时,其意义完全与疑问词相同,即when表示什么时候,where表示哪儿,引导两种从句时,都在从句中做状语。
如:I still remember the day when I first came to Beijing . 句中的when 相当于“on the day”它没有疑问词“什么时候”的意义,因此是定语从句。
I have no idea when she will be back . when与idea毫无意义上的关联,其意思是“什么时候”,因而是同位语从句。
易混点四:reason后面的名词性从句reason做主语时,后面的表语从句表示原因是要用that引导,一般不用because或why,而用it,this或that做主语时,后面的表语从句可用because或why引导。
1.“The reason +连系动词+that“引导的表语从句。
本句型的意思是:理由是:。
The reason was that he fell ill.2.It(或This、That)+连系动词+the reason+why引导的定语从句。
本句型意为:这就是。
的原因(理由)3. It(或This、That)+连系动词+the reason+because引导的表语从句。
本句型意为:这是因为。
;这是由于。
的缘故。
That was because he fell ill.4. It(或This、That)+连系动词+why引导的表语从句。
本句型意为:这就是。
的原因。
That was why he fell ill.易混点五:what引导的一种独特的名词性从句阅读文中我们经常碰到这样的句子:After what seemed an endlesswait ,it was at last his turn to step into the consulting room.(诊察室)句子中的what seemed的理解,对于中学生而言是个难点,下面做以总结:1.结构:What引导的插入句+名词2.说明:What引导的这个插入句对后面的名词起解释或说明的作用。
省略它,主句的结构仍然完整。
从意义上看,可将它视为定语,即句子做前置定语,修饰后面的名词,所以翻译时总是作为定语来处理。
3.用法:(1)表示对某事物的看法或态度(2)表示不肯定、无把握极不确切的人或物(3)表示对后面的名词的解释或强调4.常见的表达形式:(1)what one call或what is called(2)what sb. know as或what is known as 或what is regarded as(3)what seem\appear(to sb.)(to be)(4)what sb. think(5)what seem /look like(6)what might be/have been5.例句He was born in what is now known as Shanghai.(他出生于现在人人皆知的上海)What is called atomic energy is actually nuclear energy.(所谓的原子能实际上就是核能)易混点六:check、make sure后面的宾语从句动词或动词短语check、make sure等做肯定句的谓语时,全句在汉语意义上虽有“是否”之意,但后面常用that做引导词。
Check that everything is in order,please.(请核对一下是否一切正常)Make sure that the door is locked before you leave the lab.(离开实验室之前,务必确保门是锁上的。
)易混点七:what、whatever、who、whoever 等引导的名词性从句我们可以通过与定语从句的转化知道两组在意义上的差别。
Whatever=anything that(无论什么)Whoever=anyone who(无论谁)Whenever=any time=no matter when(无论何时)Wherever=any place=no matter where(无论何地)这都是泛指。
