下面就来总结一下高考中常见的名词性从句知识点。
1. 主语从句主语从句在句子中充当主语的角色,常用的引导词有:that, whether/if, who, what, which, how等。

高考英语名词性从句高频考点易混点高频考点一:考查that与what的区别在引导名词性从句时,从属连词that一般要注意三个"不":1.不省略。
当从属连词that引导的主语从句位于句首时,that不省略;that引导同位语从句时,一般不省略。
2.不作成分。
that 在名词性从句中不作任何句子成分。
3.无实义。
that 在名词性从句中没有实义。
在引导名词性从句时, what一般要注意一个"不",一个"有词义",一个"作成分":1.不省略。
what 引导名词性从句时,不省略。
2.有词义。
what 引导名词性从句时,有词义。
一般表示"……的东西/事情等",这一用法与that 的用法不一样。
3.作成分。
what 在引导名词性从句时,在从句中充当成分。
这一用法与that 的用法不一样。
例如:Nobody believed his reason for being absent from the class that he had to meet his uncle at the airport.该句中,that引导同位语从句,在句中不作任何成分,不能省略且无词义。
What the teacher said had a good effect on the children.what引导主语从句,在句中有词义。
高频考点二:it放在句首,真正的主语是that从句常用句型如下:① It+系动词+n.+ that从句;② It+系动词+adj.+ that从句;③ It+be+动词的过去分词形式(如said, reported, suggested等)+that从句;④ It+特殊动词(appear, seem, happen, matter, turn out, work out等)+that从句。
高频考点三:考查whether与if的区别whether与if在作"是否"讲时,是可以互换的。

名词性从句分为主语从句、宾语从句、表语从句和同位语从句。
在高考英语中,名词性从句是考查的重点之一,我们需要对名词性从句的结构和用法有透彻的理解。
下面是关于名词性从句的一些重要知识点:1.主语从句主语从句在句中充当主语的作用。
主语从句通常以that引导,也可以用whether或if 引导。
例如:- That he is guilty is certain.- Whether we will win the game is yet to be seen.- If it will rain tomorrow is still uncertain.2.宾语从句宾语从句在句中充当宾语的作用。
宾语从句通常以that引导,也可以用whether或if 引导。
需要注意的是,当主句的动词是说、tell、ask、think、believe、know等表示说话、思考、感觉的动词时,常用连词that引导宾语从句,但如果宾语从句的主语与主句的主语相同,可以省略连词that。
例如:- I know that he is a good student.- She asked me if/whether I had finished my homework.- He told her (that) he loved her.3.表语从句表语从句在句中充当表语的作用。
表语从句通常以that引导,也可以用whether或if 引导。
例如:- The fact that he didn't come is disappointing.- The question is whether we should proceed with the plan.- My concern is if/whether we have enough time.4.同位语从句同位语从句用来解释或说明前面名词的具体内容或意义。
高考英语名词性从句知识点一、that从句1、主语从句that从句作主语时,常用it作形式主语,常见的句型有:It+be+形容词(obvious, true, natural, surprising, good, wonderful, funny, possible, likely, certain, probable, etc. ) + that 从句It+be+名词词组(no wonder, an honor, a good thing, a pity, no surprise, etc. ) + that 从句It+be+过去分词(said, reported, thought, expected, decided, announced, arranged,etc. ) + that 从句that可以省略,但that从句位于句首时,that不能省略。
2、宾语从句(1)常见的可以接that从句作宾语的动词有see, say, know, imagine, discover, believe, tell, show, think, consider, be sure, be afraid 等。
在可以接复合宾语的动词之后,如think, make, consider等,可以用it作形式宾语。
(2)That从句一般不能充当介词宾语,偶尔可作except, in的宾语。
3、表语从句(that不可省略)4、同位语从句连词that引导同位语从句时,应在某些抽象名词之后,如:fact, hope, desire, thought, suggestion, idea, news, problem, possibility 等,对前面的名词起补充说明的作用,that 在从句中不担当任何成分,不能省略。
二、whether/if 从句1>在表语从句和同位语从句中,只能用whether不能用if;当主语从句放于句首时,只能用whether不用if;当it作形式主语,主语从句放在句末时用whether或if均可;discuss后引导宾语从句时,必须用whether。
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”。
高考英语复习名词性从句十大考点及热点问题教案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。
因为它是从句,因此具有句子的特点,有主、谓成份;同时又具有名词性特点,所以可以在句子中作主语、宾语、表语或同位语。
名词性从句是中学英语学习的重点,也是高考的主要考点之一。
无论是从高考的角度,还是从英语学习本身来讲,名词性从句的以下知识,都是我们必须弄懂和掌握的重点和热点问题。
一、引导词what与that的用法区别。
引导主、宾、表语从句时,what要充当主语、宾语或表语等句子成分,that不作任何成分,只在语法上起连接的作用。
例如(NMET’96):____ we can’t get seems better than ____ we have.A. What; whatB. what; thatC. That; thatD. That; what解析:本句包含一个主语从句和一个宾语从句,且两个从句都缺乏宾语,可见两个引导词都必须充当成分,所以答案是A。
又如(上海高考‘98):____ caused the accident is still a complete mystery.A. WhatB. ThatC. HowD. Where解析:该题答案是A,what在主语从句中作主语,即作谓语动词caused的执行者。
在下面的例句中,that不充当任何成份,只起语法连接作用(因为句子本身不缺成分):That the former Iraq president Saddam was captured has been proved.二、引导词whether和if的用法区别。
通常,引导主语从句、表语从句和引导同位语从句时,要用连词whether,不用if;习惯上也只能说whether or not,而不说if …or not。
例如(MET92):____ the 2000 Olympic Games will be held in Beijing is not known yet.A. WheneverB. IfC. WhetherD. That解析:试题中的从句位于句首,不难知道这是一个主语从句,所以答案是C。
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。
