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。

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。

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，名词性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。
二、名词性从句的引导词1、连接代词：who, whom, whose, what, which, whoever, whatever 有词义，在从句中担任成分，如主语、表语、宾语、或定语等。

名词性从句详解及练习
各类从句详解英语从句可以分为名词性从句、定语从句和状语从句三大类：下面我们逐一进行说明：一、名词性从句（主语从句、表语从句、宾语从句、同位语从句）主语从句、表语从句、宾语从句和同位语从句在复合句中的充当的成分和其名称相同，分别作主句的主语、表语、宾语和同位语。
上述这四种从句均被称为名词性从句。
所有的名词性从句均不能用逗号分开，并且它们都用相同的关联词，关联词如下：①主从连词：that (无意义), whether (是否), if (是否)（在句子中不充当任何成分）②连接代词：who (谁), whom (谁), whose (谁的), what (什么), which (哪一个)③连接副词：when (什么时候), where (什么地方), how (怎样), why (为什么)主从连词只起连接作用，连接代词和连接副词除了起连接作用外，还充当从句某一个成分。
另外，可以用whatever, whichever, whoever, who(m)ever等连接代词引导名词性从句，来加强语气。
下面分别对各种名词性从句进行介绍（一）主语从句（subject clause）在主句中用作主语的主谓结构称之为主语从句。
例如：That he will come to the discussion is certain.他来参加讨论是确定的。
That the moon moves round the earth is well known to all of us.月球绕地球转动，这是我们大家都熟知的。
When the meeting is to be held has not yet been decide.会议什么时候召开还没有决定。
主语从句放在句首，句子常常显得比较笨重，因此通常可以把it放在句首，作形式主语，而将主语从句放在后面。
例如上面的句子可以分别改写为：It is certain that he will come to the discussion.It is well known to all of us that the moon moves round the earth.It has not yet been decide when the meeting is to be held.下面再举一些例句：What they are after is profit.他们追求的是利润。

第一章名词性从句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主句中作主语的句子，它由连接词引导，通常位于谓语动词之前。
1. 连词：在从句中不充当任何成分，常用见的引导主语从句的连词有三个，即that, whether和if.That he got the first prize excited him much. 他获得一等奖一事使他非常兴奋。
Whether you can succeed or not depends on how hard you work at it. 你能否功取决于你努力的程度。
注意：whether引导的主语从句常用置于句首，表示“是否”之意；if引导主语从句时不置于句首。
2. 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.What we should do with the problem is undecided. 我们如何处理这上问题还未作出决定。
3. 连接副词：在从句中起副的作用，常作从句的状语，表示时间、地点、原因、方式等。
常见的连接副词有when, where, how, why, whenever, wherever, however等。
How they will solve the serious problem has not been decided. 他们将如何解决这个严重的问题还没有决定。
Why he did that wasn’t quite clear. 他为什么做那件事还不十分清楚。
4. 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。
常见的有以下几种：(1)It ＋系动词＋形容词＋that从句It is quite clear that the whole project is doomed to failure. 很清楚，整个计划注定要失败。
(2)It is ＋系动词＋名词＋that从句常见的用于此结构的名词有：a pity 遗憾，a fact 事实，an honor 荣耀，a wonder 奇迹，no wonder 难怪, good news 好消息，等。
It’s no wonder that you’ve achieved so much success. 难怪你已取得了如此大的成功。
It’s a pity that you didn’t attend her party. 你没有参加她的聚会真是遗憾。
(3)It ＋系动词＋过去分词＋that从句It is said that no passengers were injured in the accident. 据说在那次意外事故中没有乘客受伤。
(4)It ＋特殊动词＋that从句常用于这种结构的动词有：seem 看上去，appear 显得，happen 碰巧，matter 关系重大，turn out 结果，occur to sb. 某人突然想起，等。
It seems to me that he objects to the plan. 在我看来，他好像反对这个计划。
It happened that I met an old friend on the street yesterday. 昨天我碰巧在街上遇见了一位老朋友。
It occurred to me that we should get in touch with the manager. 我突然想起我们应该与经理联系。
5. 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。
（2）It is said /reported…结构中的主语从句不可提前。
例如：正确表达：It is said that President Jiang will visit our school next week.错误表达：That President Jiang will visit our school next week is said.（3）It happens/occurs…结构中的主语从句不可提前。
例如：正确表达：It occurred to him that he failed in the examination.错误表达：That he failed in the examination occurred to him.（4）It doesn’t matter how/whether …结构中的主语从句不可提前。
例如：正确表达：It doesn’t matter whether he is wrong or not.错误表达：Whether he is wrong or not doesn’t matter.（5）含主语从句的复合句是疑问句时，主语从句不可提前。
例如：正确表达：Is it likely that it will rain in the evening?错误表达：Is that will rain in the evening likely?二．宾语从句宾语从句就是在复合句中作宾语的名词性从句，通常放在主句谓语动词(及物动词) 或介词之后。
1. 作动词的宾语(1) 由that引导的宾语从句(that 通常可以省略)I heard that be joined the army. 我听说他参军了。
(2) 由what, whether (if) 引导的宾语从句She did not know what had happened.她不知道发生了什么。
I wonder whether you can change this note for me.我想知道你是否能帮我改一下笔记。
(3) 动词＋间接宾语＋宾语从句。
She told me that she would accept my invitation.她对我说她会接受我的邀请。
2. 作介词的宾语Our success depends upon how well we can cooperate with one another.我们的成功取决于我们之间的合作。
3. 作形容词的宾语I am afraid (that) I’ ve made a mistake.我恐怕我已经犯了一个错误。
注意：that 引导的从句常跟在下列形容词后作宾语：anxious, aware, certain, confident, convinced, determined, glad, proud, surprised, worried, sorry, thankful, ashamed, disappointed, annoyed, pleased, hurt, satisfied, content 等。
也可以将此类词后的that 从句的看作原因状语从句。
4. it 可以作为形式宾语it不仅可以作为形式主语，还可以作为形式宾语而真正的宾语that 从句则放在句尾，特别是在带复合宾语的句子中。
We heard it that she would get married next month. 我听说她下个朋就会结婚了。
5. 后边不能直接跟that 从句的动词这类动词有allow, refuse, let, like, cause, force, admire, condemn, celebrate, dislike, love, help, take, forgive等。
这类词后可以用不定式或动名词作宾语，但不可以用that引导的宾语从句。
如：正确表达：I admire their winning the match.错误表达：I admire that they won the match.6. 不可用that从句作直接宾语的动词有些动词不可用于“动词＋间接宾语＋that从句“结构中，常见的有envy, order, accuse, refuse, impress, forgive, blame, denounce, advise, congratulate等。
例如：正确表达：He impressed the manager as an honest man.错误表达：He impressed the manager that he was an honest man.7. 否定的转移若主句谓语动词为think, consider, suppose, believe, expect, fancy, guess, imagine等，其后的宾语从句若含有否定意义，一般要把否定词转移到主句谓语上，从句谓语用肯定式。
例如：I don’t think this dress fits you well. 我认为这件衣服不适合你穿。
8. 复杂的特殊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, except, guess, say等。
Who do you guess will be our new headmaster? 你猜谁会是我们的新校长?How do you suppose they will go to Shanghai? 你猜他们会乘坐什么去上海?9. 宾语从句中引导词that不可省略的情况。
(1). 介词except, but, besides, in等后跟that引导的宾语从句时。
The Swede stood quite still, except that his lips moved slightly.那个瑞典人站着一动不动，只是嘴唇还微微在动。
(2). that引导的宾语从句和主句之间有插入语时。
