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。

由于在多数情况下，主语、表语、宾语或同位语这四种句子成分由名词性词类充当，所以，我们把这些作用相当于名词的从句统称为名词性从句，把充当主语、表语、宾语或同位语的从句分别称为主语从句、表语从句、宾语从句或同位语从句。
也就是说充当什么成分就叫什么从句。
名词性从句由连接词（或关联词）引导。
常用的连接词有：连接词作用whether 是否that (本身无词义)只起连接词作用，引导从句，在从句中不作任何成分who, whom, whose which 哪一个what 什么，所…的在从句中分别作主语、宾语和定语在从句中分别作主语、宾语和定语在从句中分别作主语、宾语和定语cwhen什么时候，where什么地方how怎样、怎么，why为什么除了起连接词作用外，还在从句中作状语疑问词（who, whom, whose, what, which, where, why, when, how）可以引导主语、宾语和表语从句。
它们的特点是：1、疑问词有本身的词义；2、疑问词在从句中担当句子成分，如主语、宾语或状语；3、这种疑问词引导的从句一律用陈述语序，不能用疑问语序。
For example:Do you know whom they are looking for? 你知道他们在找谁吗？（宾语从句，陈述语序。
不能是whom are they looking for?）I don’t know who did it.我不知道这是谁干的。
（宾语从句。
在从句中如果疑问词作主语，其陈述语序和疑问语序一致。
）She asked me where I had been.她问我到哪儿去了。
（宾语从句。
陈述语序，不能是where had I been. 直接引语，间接引语。

（从句）Do you remember how he came? 你记得他怎么来的么？（从句）二、语序当名词性从句要采用陈述句语序。
由一个含疑问意义的连词引起时，必须将该连词放在名词性从句的开头，且该从句语序不能倒装。
What we can't get seems better than what we have.我们得不到的似乎比我们所拥有的要好。

He asked how much I paid for the violin.他问我花了多少钱买这个小提琴。
三、时态的呼应名词性从句特别是宾语从句中谓语动词的时态要与主句中谓语动词时态要相呼应，主要有下列几种情况：（1）如果主句中的谓语动词是一般现在时态，从句的谓语动词的时态不受主句谓语动词时态的制约，从句的谓语可根据意思的需要使用任何一种时态。
I wonder why Jenny hasn’t written us recently. We should have heard from her by now.我不知道为什么珍妮最近没有给我们写信。

名词性从句最详讲解及习题与答案
名词性从句名词性从句是在句子中起名词作用的句子。
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。
连接词引导名词性从句的连接词可分为三类：1.连词：that （本身无意义。
引导单一的宾语从句时that常可省略，但引导主语从句、表语从句、同位语从句时that通常不被省略）whether,if （均表示“是否”）as if ,as though （均表示“好像”，“似乎”）◆以上在从句中均不充当任何成分2.连接代词：what/ whatever, who/ whoever, whom/ whomever, whose/whosever, which/whichever.有词意，在从句中充当主语，宾语，表语，定语等。
3.连接副词：when/ whenever, where/ wherever, how/ however, why.有词意，在从句中充当状语。
主语从句作句子主语的从句叫主语从句。
主语从句通常由连词that，whether，和连接代词what，who，which，whatever，whoever以及连接副词how，when，where，why等词引导。

例如：What he wants to tell us is not clear. 他要跟我们说什么，还不清楚。
Who will win the match is still unknown. 谁能赢得这场比赛还不得而知。

高中英语从句大全一．名词性从句起名词性作用的从句叫名词性从句英语当中其名词性作用的成分有主语，宾语，表语，同位语，当这些成分有一个句子来代替就构成了名词从句，主要有主语从句，宾语从句，表语从句，同位语从句。

而whether有词义，意为、“是否”。
这时主句的主语常常是些抽象名词，如question，trouble，problem等。
表语从句对主句主语进行说明、解释，使主语的内容具体化。
The trouble is that I have lost his addressThe question is whether they will be able to help us.问题是他们是否能帮我们。

Go and get your coat.It's where you left it.I had neither a raincoat nor an umbrella.That’s why I got wet through.That is how mice ruin many stores of grain every year.That is what he is worried about.5、由连词because，as if/as though等引导的表语从句。
He looked just as he had looked ten years before.他看起来还与十年前一样。
注：从属连词if一般不用来引导表语从句，但as if却可引导表语从句，如：All this was over twenty years ago，but it’s as if it was only yesterday.这都是20多年前的事了，但宛如昨天一样。
能跟表语从句的谓语动词一般为系动词be，seem，look等。

It looked as if it was going to snow.That's because we never thought of it..It seems as if he didn’t know the answer.另外，在一些表示“建议、劝说、命令”（suggestion，proposal，order，plan, advice, request, idea）的名词后面的表语从句中，谓语动词用虚拟语气。
