名词性从句
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、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。
引导名词性从句的连接词可分为三类：
连接词：that, whether, if, as if (不充当从句的任何成分)
连接代词：what, whatever, who, whoever, whom, whose, which, whichever
连接副词：when, where, how, why
（一）主语从句
在复合句中做主语。引导词有：连接词whether, that; 连接代词who, whom, what, whose,；连接副词when, where, why, how以及由疑问词+ ever构成的词.
注意：引导主语从句只能用whether不用if；that引导主语从句本身无意义也不在从句中充当句子成分，但不能省略。
e.g. Whether we’ll go swimming tomorrow depends on the weather.
That he got the first prize surprised everyone.
大部分连接词引导的主语从句都可以置于句末，用 it充当形式主语。
It is not important who will go.
It is still unknown which team will win the match.
用it作形式主语的that-从句有以下四种不同的搭配关系：
a. It + be +形容词+ that-从句
e.g. It is necessary/important/obvious that…有必要/ 重要的是/很明显……
b. It + be + -ed 分词+ that-从句
e.g. It is believed/ known to all / said / reported that…人们相信/众所周知……
It has been decided that…已决定……
c. It + be +名词+ that-从句
It is common knowledge / no wonder /a pity / a fact / a surprise that…
d. It + doesn’t matter / makes no difference that….
e.g. It makes no difference whether he comes or not.
（二）宾语从句
在复合句中做宾语。引导词有连接词that, whether, if; 连接代词what, who whom, which, whose连接副词when, where, how, why以及由疑问词+ ever构成的词。其中，if和whether可以互换；但在做介词的宾语时一般用whether；that引导宾语从句可以省略。
e.g. He asked me whether/if I could help him. I’ll give you however much money you want.
Can you tell me where she has gone? We should find out whether the museum is open.
如果宾语从句后有宾语补足语，则用it作形式宾语，从句后置。
e.g. I find it strange that he has no textbook.
动词think, believe, suppose, expect, imagine, consider, fancy, guess等后接宾语从句，且主句主语为第一人称时，从句的否定转移到主句去。
e.g. I don’t think you are a good liar.
（三）表语从句
在句中做表语，引导词有：that, whether, as if (好像), who, which, what, when, where, how, why.
注意：引导表语从句只用whether不用if ; that不做句子成分但不能省略。
e.g. That was just what I wanted. The questions is whether it worth doing.
My suggestion is that you should take off your overcoat.
It looks as if it’s going to rain.
(四) 同位语从句
在复合句中作同位语。其引导词有:that, whether, how, when, where. 一般跟在某些抽象名词的后面用以说明名词所表示的具体内容，如news, fact, message, information, promise, question, hope, thought, desire, idea, possibility等注意：that只起引导作用，不做句子成分，但不能省略；同位语从句中只用whether不用if.
Mother made me a promise that she would buy me a new hat.
My question how I shall get in touch with him hasn’t been answered yet.
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.
比较：whether与if 均为"是否"的意思。但在下列情况下，whether 不能被if 取代：
1. whether引导主语从句并在句首Whether he will come is unknown.
2. 引导表语从句和同位语从句The question is whether it’s worth doing.
3. whether从句作介词宾语We should find out whether the museum is open.
4. 从句后有"or not"
that 引导同位语从句与定语从句的区别：
定语从句是对名词进行修饰限制，同位语从句是对名词具体内容的阐述。that 在定语从句中可作主语或宾语（可省略），在同位语从句中不充当句子成分也不能省略。
e.g. The story that / \ /which he told me may not be true.
The story that he has made a fortune may not be true.

英语语法：名词性从句语法讲解 时间：2016-10-08作者：来源：精品学习网 笔者在此就名词性从句中的几大易错点进行分析，希望对同学们有所帮助。 [关系代词和关系副词的误用] 例1 （2016·全国卷Ⅰ） My uncle is the owner of a restaurant close to that I live. 解析 that→where。本题考查宾语从句，引导词在从句中充当地点状语，所以将that改为where。 例2 （2015·全国卷Ⅱ） As natural architects， the Pueblo Indians figured out exactly thick the adobe walls needed to be to make the cycle work on most days. 解析 how。根据语境和空后的形容词thick可知应用how引导宾语从句，此处表示要弄清楚到底土坯房的墙需要“多”厚。故答案为how。 点拨若从句缺少主语、宾语、表语或定语，则考虑用关系代词；若从句缺少时间、地点、原因、方式等状语成分，则使用关系副词 （when/where/why/how）。 [if和whether的误用] 例3 He asked her the question if they can be friends. 解析 if→whether。question后为同位语从句，只能用whether来引导，故而将if改为whether。 例4 It doesn’t matter so much you will come or not. 解析考查主语从句。句意：你来还是不来，这不怎么重要。代词it作形式主语，真正的主语是whether引导的主语从句。 点拨在表达“是否”这一意思时，我们经常会用到whether和if，但以下几种情况只用whether不用if： 1. 在表语从句、主语从句、同位语从句中； 2. 在介词后的宾语从句中。如：It all depends on whether they will

A. That; that B. What; how C. What; that D. 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。 【点评】考查名词性从句，本题涉及what引导的主语从句和that引导的表语从句。 3．It________that the road will be closed tomorrow for repairs. A. was announced B. has been announced C. had been announced D. would be announced 【答案】 B 【解析】【分析】本题考查动词的时态和语态。题干句子中that到句子结束是宾语从句，且从句动词用“will＋动词原形”表示将来，由此推断出空白处谓语动词应用现在的某种时态，在所给四个选项中，只有B项正确。 【点评】考查现在完成时的被动语态，其结构是have/has +been +done。需要注意宾语从句的时态。主句用现在时，从句所需的任何时态。 4．_______ are playing an important part is well known to us all. A. That who B. Those who C. Who that D. Who 【答案】 D 【解析】【分析】考查主语从句。句意：谁起着重要作用，这是众所周知的。主语从句缺少引导词，从句缺少主语，故选D。 5．Has it been announced ______?

名词性从句 名词性从句是由if, whether, that 和各种疑问词充当连接词所引导的从句，其功同名词一样。 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。被强调部分指人是也可用who/whom。例如：
It is a pity that you didn't go to see the film. It doesn't interest me whether you succeed or not. It is in the morning that the murder took place. It is John that broke the window. 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

英语名词性从句练习全集及解析 一、初中英语名词性从句 1．________ manners are very important in every country is known to all，but the trouble is that different countries have different ideas about ________ good manners are. A. That; what B. That; that C. What; that D. What; what 【答案】 A 【解析】【分析】句意：众说周知，礼貌在每一个国家中都是非常重要的，但是麻烦是，不同的国家对于什么是良好的礼貌有着不同的认识。逗号前有两个谓语动词，一个是are，一个是is known，故是两句话，需填连词连接这两句话，根据句意可知，前面是主语从句，故填that，此处的that，只起连接作用不作任何成分。about是介词，其后是个句子故应填连词把这两句话连接起来，所缺词作are的表语，故填what。因此选A。 【点评】考查名词性从句，本题涉及that引导的主语从句和what引导的宾语从句。 2．Some people believe _______ has happened before or is happening now will repeat itself in the future. A. whatever B. whenever C. wherever D. no matter what 【答案】 A 【解析】【分析】句意：一些人认为之前发生的或现在正在发生的任何事情在将来都会重复发生。Whatever has happened before or is happening now是一个主语从句，whatever既引导起这个主语从句，也在句中做主语。BC项都属于副词的性质，都不能做主语，通常只能做状语；no matter what只能用来引导状语从句，故选A。 【点评】考查名词性从句，本题涉及"特殊疑问词+ever"引导的主语从句。 3． is even more important is the earth cooled down, water began to appear on its surface. A. When; that; when B. What; whether; as C.

A. when are the planes to take off B. that are the planes to take off C. where are the planes to take off D. when the planes are to take off 【答案】 D 【解析】【分析】句意: 飞机什么时候起飞已经宣布了吗？此处是when引导的主语从句，且要用陈述句语序，故选D。

What was it that; Get 【答案】 C 【解析】【分析】句意：——是什么让她对她自己感到羞愧？——是她获得了她班上的最低分让她惭愧。A中的what是句子的主语，但是because引导的从句不作主语，是原因状语从句，故排除；B的第一空是错误形式，故排除；C、D两项的第一个选项是一样的，说明第一个题干是一个强调句型，特殊疑问句下的强调句型，有what引导；第二个空是对what的回答，因为what是上一句的主语，That she got the lowest mark in her class是从句，可以作主语；而D项的get是动词原形，不能作主语，故答案为C。 【点评】考查强调句型的使用和对特殊疑问句的回答，注意问什么回答什么，也就是说疑问词what是句子的主语，回答的内容也需要在句子中能作主语。 2．It was he said disappointed me.
