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, why1. 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。

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。
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。

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, why1. 主语从句（两种结构，三类连接词）两种结构1.主语从句位于句首：What he wants is a book.Who kept the door open all night was unknown.2.主语从句位于句尾，it 作形式主语。

高中英语-名词性从句 专题讲解及巩固练习(含答案)
高中英语名词性从句专题讲解及巩固练习定义：起名词性作用的从句，叫名词性从句。
本来该由名词充当的主语、宾语、表语和同位语部分，换由一个句子来充当，这样的句子就是名词性从句。
【归纳】1.只能用whether,不能用ifa.主语从句b. 表语从句c. 同位语从句e. 介词后的宾语从句f. whether to do 做动词宾语不能用if to do.g.whether or not 连在一起引导宾语从句时不用if.2.that和what的区别what除起连接作用外，还在名词性从句中充当成分，可做从句的主语、宾语、或表语。
that在名词性从句中不充当任何成分，只起连接作用。
例：I have no doubt that he will come.I have no idea what he did that afternoon.一．主语从句：在复合句中作主句的主语。
●__________ he is a famous singer is known to us.●__________ he will go to America is not yet fixed.●__________ she’s coming or not doesn’t matter too much.●__________ broke the glass yesterday is not clear.【keys】That; When/How; Whether; Who【归纳】1.为避免主语冗长,句子头重脚轻, 经常用it作形式主语, 主语从句放在后面作真正的主语。
例：That her hair was turning gray worried her a lot.-----It worried her a lot that her hair was turning gray.常考句型：It’s likely / possible / important / necessary / clear that…很可能/ 重要的是… / 必要的是… / 很清楚…It’s said / reported that…据说/据报道…It seems / appears / happens that…显然、明显、碰巧…It’s been announced / declared that…已经通知/宣布…It’s no wonder that…并不奇怪/无疑…It’s a pity/a fact /a common knowledge / a common saying that…2.if不能引导主语从句，只能用whether3.单个的主语从句作主语时，谓语动词用句单数形式；如果是两个或两个以上的主语作主语，谓语动词则视情况而定。
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。

高中英语讲义---- 名词性从句（主从、表从、宾从，同从）1，陈述句做名从用连词that + SV, that 表主句肯定从句完整，不做成分。
主从可用it 做形式主语，宾从第一个that 可省略。
You study hard.主从：That you study hard is known to us.= It is known to us that you study hard.表从：My opinion is that you study hard .宾从：I think (that) you study hard. …and that (不能省略)….同从：My opinion that you study hard is known to us. *比较同从和主从！●一般抽象名词后对其进行解释和说明的完整句子就是其同位语从句，不完整就是定语从句。
I appreciate your idea that we have an exam every week. （that后完整—同从）I appreciate your idea that you came up with last time.（that后不完整---定从）2，一般问句做名从用连词whether(是否) + SV，whether表主句不肯定从句完整，宾从中可用if（介词后或宾从后有or not时只用whether）。
Does your friend like English ?主从：Whether your friend likes English isn’t clear .=It isn’t clear whether your friend likes English.表从：My question is whether your friend likes English.宾从：I don’t know whether/ if your friend likes English.同从：My question whether your friend likes English isn’t clear.3, 特殊问句做名从用疑问词（连词）+ SV, 疑问词做主语时直接+谓语。

高频考点1，当主从句都缺成分时指物用what/whatever/whichever(有范围), 指人用whoever / whomever(做宾语).The buildings have built in _what_ was farmland. _What_ you need is courage.The prize will be awarded to _whoever_ has won the game. You can choose _what/whatever/whomever_ you like.Of all, you can choose _whichever_ you like .2, No matter+疑问词，只能引导让步状语从句（主从句逗号分开），疑问词+ever 既可引导让步状从，又可引导名从（从句在主句中做成分）。
_No matter who / whoever-has broken the law , he ‘ll be punished ._Whoever_ has broken the law will be punished.3, 抽象名词（fact, news/word, hope, desire, thought, suggestion, idea, problem, possibility/chance ,rumor,concept…）后常用that 引导同从。
