(完整版)名词性从句讲解及专项练习习题及其解答
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。

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。

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)。

高中英语高考名词性从句高频考点易混点整理(含练习和答案)
高考英语名词性从句高频考点易混点高频考点一：考查that与what的区别在引导名词性从句时，从属连词that一般要注意三个"不"：1.不省略。
当从属连词that引导的主语从句位于句首时，that不省略；that引导同位语从句时，一般不省略。
2.不作成分。
that 在名词性从句中不作任何句子成分。
3.无实义。
that 在名词性从句中没有实义。
在引导名词性从句时， what一般要注意一个"不",一个"有词义",一个"作成分"：1.不省略。
what 引导名词性从句时，不省略。
2.有词义。
what 引导名词性从句时，有词义。
一般表示"……的东西/事情等"，这一用法与that 的用法不一样。
3.作成分。
what 在引导名词性从句时，在从句中充当成分。
这一用法与that 的用法不一样。
例如：Nobody believed his reason for being absent from the class that he had to meet his uncle at the airport.该句中，that引导同位语从句，在句中不作任何成分，不能省略且无词义。
What the teacher said had a good effect on the children.what引导主语从句，在句中有词义。
高频考点二：it放在句首，真正的主语是that从句常用句型如下：① It+系动词+n.+ that从句;② It+系动词+adj.+ that从句;③ It+be+动词的过去分词形式（如said, reported, suggested等）+that从句；④ It+特殊动词（appear, seem, happen, matter, turn out, work out等）+that从句。
高频考点三：考查whether与if的区别whether与if在作"是否"讲时,是可以互换的。

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。
连接代词（what/which/who/whose…）表主句不肯定从句不完整，连接副词（when/where/why/how）表主句不肯定从句完整。
Where did you go just now ?主从：Where you went just now isn’t clear.= It isn’t clear where you went just now.表从：My question is where you went just now.宾从：I wonder where you went just now.同从：My question where you went just now isn’t clear.●当主句为现在时态从句时态不受影响，当主句为过去时态从句就应该变成过去的某种时态，但客观真理总用一般现在时，有固定过去时间总用过去时。
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。
