高中英语名词性从句知识讲解以及练习题附答案一、名词性从句概述名词性从句是一种充当名词作用的从句，通常在主句中作主语、宾语、表语或同位语。
它通常由引导词（如that, whether, if, who, whom, whose, which, what等）引导，并且从句中含有一个主语和谓语。
名词性从句的种类有很多，包括主语从句、宾语从句、表语从句和同位语从句等。
下面我们将逐一介绍这些从句。
二、主语从句主语从句作为一个名词，通常位于句首，是一个句子，主要作用是作为主句的主语。
引导主语从句的词：What (什么)；Whether (是否)；If (是否)；That (那个)。
例句：What he said is true. (他说的是真的。
)Whether it will rain tomorrow is uncertain. (明天是否会下雨还不确定。
)If you go, I will go too. (如果你走，我也跟着走。
)That he is coming is good news. (他来的消息是好消息。
)注意：主语从句的谓语动词通常要用单数形式。
What引导的主语从句通常用来表示“事物”的概念。
三、宾语从句宾语从句是一个名词，通常位于主句的动词后面，作为主句的宾语。
它可以由常见的宾语从句引导词引导，例如whether, if, that, who, whom, whose, what, when, where, how等。
引导宾语从句的词：Whether (是否)；If (是否)；That (那个)；Who (谁)；Whom (谁)；Whose (谁的)；What (什么)；When (何时)；Where (何处)；How (如何)。
例句：I know that he is coming. (我知道他要来。
)I wonder if he is telling the truth. (我想知道他是否说了真话。

（完整版）高考英语【名词性从句】专题十名词性从句第一节基本知识与基本概念【什么是名词性从句？】顾名思义，主语从句在句子中作主语。
有时本身出现在主语的位置上，也有时出于句子结构的考虑退到句子的尾部，前面用形式主语it代替。
从句作主语时，谓语动词一般为单数形式。
如: What I saw was beyond any verbal description.That his hair was turning grey worried him a bit.Why the company denied the contract is still unknown.When and where the government will build a city square is under discussion.It is pretty annoying that a small part of the machine is missing.It remains to be seen whether the new novel will be well received.【宾语从句】在句子中作宾语的从句就是宾语从句。
由于这是同学们接触比较早的一种从句，应该问题不大。
所以在近年的高考题中，以宾语从句的知识作为考点的题目较少。
但是，宾语从句也有自己的特殊情况，如介词的宾语，形容词的宾语，宾语从句提前和并列的宾语从句等现象。
如：We assumed that there would be more than 100 guests.He told the police in detail what he saw and heard.Nobody is sure what humans will look like in a million years.That will depend on whether they can get the chance.Whether I will have the time I am not sure at the moment.The conductor complained that we were not gifted in singing and that he would never come again.【表语从句】表语从句的最重要脸谱就是它们应该出现在系动词的后面。

高二英语名词性从句要点精讲高考重点要求1．掌握主语从句、宾语从句、同位语从句、表语从句的基本句型结构。
2．弄清名词性从句的连词意义，掌握其用法。
3．根据句子语义确定使用何种从属连词。
名词从句分为：主语从句、宾语从句、同位语从句、表语从句。
我们看一下它们的属性。
如：that he failed the entrance examination1)________made all of us surprised.2)He told me ________.3)The result is _______.4)The news _____surprised me.我们在四个句子中可以填入that he failed the entrance examination这个句子，发现都可成立。
从上例不难看出，从本质上讲，这四类句子的属性是相同的，即：都起名词作用，只不过称谓不同,在整个句子中担当成分不同而已。
纵观几年高考，对复合句的考查重在连词，名词从句也不例外，基本上是针对引导词设题。
引导词的分类：1．连接代词：what , who ,whom ,whose , which ，whatever,whoever,whichever,且这些词在从句中担当主、宾、表、定语作用。
2．连接副词：why, when , where, how 在从句中充当时间、地点、原因、方式、程度状语。
whether , if在从句中不充当成分，但整个句式中不可缺少，用以体现事件的不确定性。
3．that 是名词从句中一个很活跃的词，但它只起连接作用，陈述某一事实，引导宾语从句时某些情况可以省略。
针对如下情况，可进行对比：1)______he will come to call on is uncertain .2)_______he will come to call on us is uncertain.3)_____ he will come to call on us makes us unhappy.从第一句中我们可以看出主语从句本身并不完整，缺少call on 的宾语，应加who;第二句中表语为uncertain ,可知主语部分为未知信息，可加入when, why ,how ,whether 等;第三句表一种已知事实，故应加入that 。
二．that ,whether, if 在名词从句中的使用情况1．that 在宾从中大多数情况下可以省略，在主、宾、表中不可省去。
但注意以下宾从中that 不可省。
I know nothing of him except that he is from Henan.(介词后宾从中的that不可省)２．whether ,if 宾语从句中可换用，但在主语从句、表语从句和同位语从句中不可用if。
但注意在宾语从句中不能用if 的情况：It all depends on whether they will support us.(从句作介词宾语时不可用if)He doesn't know whether to stay or not. （后直接跟不定式时，不能用if）Please let me know if you like it.(这句是有双重意思的，如果视为宾语从句，就应换为whether.否则就引起歧义。
三．从句的区分1)He tells me his idea ___we reduce the cost .2)We are discussing the idea____he came up with yesterday.第一句中we reduce the cost 应视为是idea 内容的一种说明，是同位语从句，而第二句中idea 可视为come up with 的宾语，缺少引导定从的关系代词that 或which ,当然可以省去关系代词。
四．分类复习中应注意的问题：1.在主语从句中it 的使用That he will come to the party is certain。
表意上并没有错误，但实际上并不太符合用语习惯，因此采用it 作形式主语，使句式平衡。
It is certain that he will come to the party.同样道理，it 也可用作形式宾语。
2．宾语从句中的情况1）时态的呼应问题。
2）特殊句式：动词suggest, insist, demand, order ,request, require等引起的从句需用虚拟句式主语+should +原形动词,should也可省。
He suggested that we should pay a visit to that town.(建议)但注意：What he said suggested that he had known the truth.(表明)同样，insistHe insisted that we do it at once.(坚持要做)He insisted that he had done nothing wrong.(坚持说一种事实)wish 引起从句时从句中时态常转为过去时态。

DWhatever与no matter whatIt is generally considered unwise to give a child ____ he or she wants．A．whatever B．no matter whatC．whenever D．no matter when此题应选A。
容易误选B。
选项C，D显然是错的，因为句中的wants缺宾语，而C，D两项不能作宾语。
至于C，D的区别，可这样描述：no matter what只能引导状语从句，而不引导名词性从句。
而whatever既可引导名词性从句（＝anything that），也可引导状语从句（＝no matter what）：1．引导名词性从句（只用whatever）：无论他做什么都是对的。
正：Whatever he did was right．误：No matter what he did was right．山羊找到什么就吃什么。
正：Goats eat whatever they find．误：Goats eat no matter what they find．2．引导状语从句（两者可换用）：无论你说什么，我都不会相信你。
