名词性从句
在句子中起名词作用的从句叫名词性从句。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，因此根据它在句中不同的语法功能，名词性从句又可分为主语从句、宾语从句、表语从句、同位语从句。
引导名词性从句的词叫做连接词，包括：
1. 连词（在名词性从句中只起连接作用，不作成分）
2. 连接代词（在名词性从句中作主语、宾语或表语）
3. 连接副词（在名词性从句中作状语）
所有的名词性从句的语序都是陈述句语序。
主语从句：是在主句中作主语的从句。它由连接词引导，通常位于谓语动词之前。连接词：
1. 连词：在从句中不充当任何成分，常见的引导主语从句的连词有that, whether。That he got the first prize excited him much.
他获得一等奖一事使他非常兴奋。

我们能否按时到达那儿还不确定。
1）that引导的主语从句：在从句中不作任何成分，也没有实际意义。一般情况
下that不可省略。

众所周知，光沿直线传播。
That you don't like him is none of my business.

2）whether引导的主语从句：常置于句首，表示“是否”之意；
if一般不引导主语从句。

importance.

连接代词：在从句中起名词或代词的作用，常作从句的主语、宾语、表语或定语，有具体意义且不能省略。常见的连接代词有who, whom, whose, what, which, whoever, whomever, whatever, whichever。

他为什么做那件事还不十分清楚。

我们在哪儿可以查他的地址还是个难题。
注意：it代替主语从句作形式主语
that从句作主语通常用it作形式主语，而将that从句置于句末。
常见的it替代主语从句的句式主要有以下几种：
1）It + 系动词 + 形容词 + that从句

II 宾语从句：在主句中起宾语作用的从句称为宾语从句。宾语从句可分为动词的宾语从句、
介词的宾语从句和形容词的宾语从句。
1. 连词that, if/ whether引导的宾语从句
引导宾语从句时，that, whether/if 都只起连接作用，在从句中不作任何成分。that无实义，在句子中可以省略；Whether/if 意为“是否”，不可省略。
He said (that) he couldn't finish his work before dusk.
他说黄昏之前他完不成任务。
Nobody knows whether/ if he likes school or not.
没有人知道他是否喜欢上学。
注意：whether/ if都意为“是否”。一般情况下，它们可以互换，口语中常用if，但在以下情况中，只能用whether：
1）与or not 紧接连用时。如：
Let me know whether or not you can come.
请让我知道你是否能来。
2）作介词的宾语从句时。如：
We are interested in whether you will attend the meeting.
我们对你是否会参加会议感兴趣。
3）引导主语从句、表语从句与同位语从句时
4）在动词不定式前时。如：
I don’t know whether to go.
2. 连接代词引导的宾语从句
who, whom, what, which, whomever, whoever, whatever, whichever等引导宾语从句，
并且在宾语从句中充当主语、宾语、表语、定语等成分, 每个连接代词都有自己特定的意义，一般不省略。

你知道谁负责这家公司吗（作主语）

你能告诉我哪个是你儿子吗（作定语）
What do you think his job is
你认为他是干什么工作的（作表语）
连接副词引导的宾语从句
when, where, why, how, whenever, wherever, however等引导宾语从句，并且在宾语从句中充当状语，表示时间、地点、原因、方式等。
（有时how much, how many等也可引导宾语从句。每个连接副词都有自己特定的意义，一般不省略。）
The police asked me how the accident happened.
警察问我事故是怎么发生的。（方式状语）
I don't know when we will meet again.
我不知道我们何时才能再见面。（时间状语）

使用宾语从句的注意事项
宾语从句的语序：在宾语从句中要用陈述句语序。

他问我第二天什么时候可以出发。

的谓语用肯定式。

我想我并不认识你。

我认为这不是他的过错，是不是
5. 宾语从句中的特殊疑问形式（又称双重疑问句）
在某些宾语从句中，宾语从句的连接代词或连接副词常被移到主句之前，
构成特殊疑问形式，其构成为：
Wh-/ How do you + vt. +宾语从句的其他部分
常见的用于此结构的动词有think, believe, consider, suppose, imagine, expect, guess, say等。

省略。

我非常清楚他住在什么地方，而且他生活得很幸福。
宾语从句用法小结：
一是关键引导词，不同句子词相异：陈述句子用that；
一般疑问是否（if, whether）替；
特殊问句更好办，引导还用疑问词。
二是时态常变化，主句不同从句异：主句若为现在时，从句时态应看意；
主句若为过去时，从句时态向前移。
三是语序要记清，从句永保陈述句。
III 表语从句
表语从句是在主句中作表语的从句，常跟在be, look, seem等系动词后。
常见的引导表语从句的连接词有that, whether; 连接代词who, whom, whose, which, what,
whoever, whomever, whichever, whatever; 连接副词when, where, how, why引导。
1. that, whether引导的表语从句
that, whether引导表语从句时只起连接作用，不作任何成分；that无实义，whether 意为“是否”。
The fact is that we should depend on ourselves.
事实是我们应该依靠自己。
The question is whether we can reduce the cost of the project.

注意：当主语为表示“计划、建议、命令、要求、主张”等的名词时，其表语从句

wh- 词包括连接代词who, whom, whose, what, which, whoever, whatever, whichever, 和连接副词when, where, why, wherever, whenever等，此类词大多
表示疑问意义，偶尔表示陈述意义。because引导的表语从句表示陈述意义。

（why引导定语从句，the reason是先行词；that引导表语从句，the reason作主语）

这次交通事故是司机酒后驾驶导致的。
（that引导表语从句，the reason用作主语）
IV 同位语从句
同位语从句是用以解释说明某一名词内容的从句，所以它总是跟在某一个名词的后面。该名词被称作先行词。
1. 同位语从句的连接词：that, whether, why, who, where, how, when等。that, whether不作成分，that无实际意义，whether表示“是否”；
其他连接词具有实义，同时在同位语从句中作一定成分。
（引导同位语从句的连接词一般都不省略）

我们有证据证明是这个人犯的罪。

3. 同位语从句与定语从句的区别：
1）先行词不同：同位语从句的先行词常是一些具有具体信息内容或一定内涵的名词，如idea, fact, news, hope, belief, suggestion, proposal, word, thought, doubt, truth, possibility, promise, order等，而定语从句的先行词可以是名词、代词、主句的一部分或是整个主句。
Word came that he had been abroad.
据说他已经出国了。（同位语从句）
The doctor whom you are looking for is in the room.
你找的那位医生在房间里面。（定语从句）
2）从句表达的含义与功能不同：定语从句是对其先行词的修饰或限制，属于形容词性从句的范畴；而同位语从句是对前面抽象名词的进一步说明和解释，属于名词性从句的范畴。
The news that our team has won the game is true.
我们队赢了那场比赛的消息是真的。
（同位语从句，补充说明news的内容）
The news that he told me yesterday was true.
（定语从句，news在从句中作told的宾语）
3）引导词的不同：有些引导词如how, whether, what可以引导同位语从句，但不能引导定语从句。
The question whether we need it has not been considered.
我们是否需要它这个问题还没有考虑。（同位语从句）
I have no idea what has happened to him.
我不知道他发生了什么事。（同位语从句）
4）that引导的同位语从句与定语从句的区别
引导词that引导定语从句时，在从句中作主语或宾语，指物时还可以用which代替，作宾语时常常省略；that在同位语从句中仅起连接作用，不充当任何成分，并且不能省略，也不能用which来代替。
The order that we should send a few people to help the other groups was received yesterday.
我们昨天收到了应派几个人去帮助其他小组的命令。
（同位语从句，是对order的具体解释，that虽不作成分，但不能省略）
The order that we received yesterday was that we should send a few people to help the other
groups.
我们昨天收到的命令是我们应该派几个人去帮助其他小组。
（定语从句，是名词order的修饰语，that在从句中作received的宾语，可以省略）

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

名词性从句讲解 在复合句中起名词作用的从句叫做名词性从句。它包括主语从句、宾语从句、表语从句和同位语从句。名词性从句是中学阶段的一个重要语法项目，在历年的高考中几乎都涉及到，并且每年的命题各有变化。分析历届高考试题名词性从句考查的焦点主要有以下六个方面 1. 考查名词性从句的语序问题 2. 考查引导词that与what的区别 3. 考查it在名词性从句中作形式主语或形式宾语的用法 4. 考查whether与if的区别 5. 考查名词性从句中的疑问词+ever引导的名词性从句与no matter+疑问词引导的状语从句的区别 6. 考查名词性从句的虚拟语气问题 语法要点剖析 一、名词性从句 主语从句、表语从句、宾语从句、同位语从句，在整个句子中所起的作用，相当于一个名词。因此，这四种从句通称为名词性从句。 引导名词性从句的连接词可分为三类： 连接词：that, whether, if （不充当从句的任何成分） 连接代词：what, whatever, who, whoever, whom, whose, which. 连接副词：when, where, how, why 1. 主语从句 作句子主语的从句叫主语从句。主语从句通常由从属连词that，whether，if和连接代词what，who，which，whatever，whoever以及连接副词how，when，where，why等词引导。that在句中无词义，只起连接作用；连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用，在从句中充当从句的成分。例如： What he wants to tell us is not clear. 他要跟我们说什么，还不清楚。 It 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。 Where the English evening will be held has not yet been announced. 英语晚会将在哪里举行，还没有宣布。 有时为避免句子头重脚轻，常用形式主语it代替主语从句作形式主语放于句首，而把主语从句置于句末。主语从句后的谓语动词一般用单数形式。常用句型如下： （1）It + be + 名词+ that从句（2）It + be + 形容词+ that从句 （3）It + be + 动词的过去分词+ that从句（4）It + 不及物动词+ that 从句 另注意在主语从句中用来表示惊奇、不相信、惋惜、理应如此等语气时，谓语动词要用虚拟语气“(should) +do”，常用的句型有： It is necessary (important, natural, strange, etc.) that … It is a pity (a shame, no wonder, etc.) that… It is suggested (requested, proposed, desired, etc.) that… 2. 宾语从句 名词句用作宾语的从句叫宾语从句。引导宾语从句的关联词与引导主语从句表语从句的关联词大致一样，在句中可以作谓语动词或介词及非谓语动词的宾语。 1. 由连接词that引导的宾语从句 由连接词that引导宾语从句时，that在句中不担任任何成分，在口语或非正式的文体中常被省去，但如从句是并列句时,第二个分句前的that不可省。例如： He has told me that he will go to Shanghai tomorrow. 他已经告诉我他明天要去上海。 We must never think (that) we are good in everything while others are good in nothing. 我们决不能认为自己什么都好，别人什么都不好。 注意：在demand、order、suggest、decide、insist, desire, demand, request, command等表示要求、命令、建议、决定等意义的动词后，宾语从句常用“（should）+ 动词原形”。例如： I insist that she (should) do her work alone. 我坚持要她自己工作。 The commander ordered that troops (should) set off at once. 司令员命令部队马上出发。 2. 用who，whom, which, whose, what, when, where, why, how, whoever, whatever, whichever等关联词引导的宾语从句相当于特殊疑问句，应注意句子语序要用陈述语序。 例如：I want to know what he has told you. 我想知道他告诉了你什么。 She always thinks of how she can work well. 她总是在想怎样能把工作做好。
