(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。

高中语法专项复习 名词性从句
语法专项复习：名词性从句一、名词性从句的类型：1.主语从句(Subject Clause)：充当句子的主语；置于句首或句末(常用“it”作形式主语)例句：Whether Native Americans arrived in California 15,000 years ago or 14,000 years ago is not important.*从句作主语时，谓语动词一般用单数。
但是what和who引导主语从句时，有时主句的谓语动词的数应与主句中表语的名词保持一致。
例句：1. What they bought was water.2. What they bought were books.“It”作形式主语的句型：1) It is/was +名词( no wonder, an honor, a good thing, a pity, no surprise…)＋主从例句：It is a pity that we can’t go.2) It is/was ＋形容词(obvious, natural, surprising, wonderful, possible, likely,certain…)＋主语从句例句：It is clear that Tom has returned.3) It is/was＋过去分词(said / reported / believed / known / thought / expected /decided / announced / arranged…)＋主语从句例句：It is said that President Jiang will visit our school next week.4) It＋动词(happens /occurs / seems…) ＋主语从句例句：It occurred to him that he failed in the examination.5) It doesn’t matter how/whether…例句：It doesn’t matter whether he is wrong or not.2.宾语从句(Object Clause)：作句子的宾语；位于动词或介词之后。
高中英语语法--名词性从句专项讲解及训练
名词性从句名词性从句一．概述：在句子中起名词作用的各种从句统称为名词性从句。
根据它们在句中的语法作用，这类从句又可分为主语从句、表语从句、宾语从句和同位语从句。
四．if, whether的区别1.引导主语从句时，如果主语从句放在句首，只能用whether不能用if引导，但是如果用it 做形式主语，而把主语从句放在句末时，也可以用if引导.2.引导宾语从句时常放在动词know, ask, care, wonder之后，if和whether均可。
3.在介词后面的宾语从句中，在表语从句、同位语从句中，表“是否”，只能用whether；4.whether和if都可以和or not连用,但是whether 之后可以直接跟or not,而if不可以。
I don’t know whether or not I will stay.（只能用whether）5.在不定式前只能用whether.如：I can’t decide whether to stay. 我不能决定是否留下。
五．与“命令、要求、建议”等相关的名词性从句中通常用虚拟语气，虚拟语气的构成是“should＋动词原形”或省去should，直接用动词原形。
六．名词性从句以考查引导词为主，同时考查时态，语序，与其它从句的区别以及混同虚拟语气的考查。
一．主语从句1.主语从句定义：在复合句中充当主语的句子叫做主语从句。
That he will succeed is certain.Whether wild life can be well protected is of great importance.Who will go makes no different.Which kind of food is the best is still not certain.What is needed for the space trip is careful preparation.How we can help the twins will be discussed at the meeting.When they’ll start the project has not been decided yet.Where he hid the money is to be found out.Why dinosaurs died out remains a puzzle.2.主语从句引导词按照在句中是否做成分主要分为三类：连词that、whether、if 连接代词、连接副词。

名词性从句重点语法讲解及专项练习习题
名词性从句讲解主语从句、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, why考点：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. 考查名词性从句的虚拟语气问题语法要点剖析：1. 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。

例如：That he is the best student in the class is obvious.What he wants to tell us is not clear.Where the English evening will be held has not yet been announced.☆有时为避免句子头重脚轻，常用形式主语it代替主语从句作形式主语放于句首，而把主语从句置于句末。
主语从句后的谓语动词一般用单数形式。
常用句型如下：（1）It + be + 名词+ that从句（2）It + be + 形容词+ that从句（3）It + be + 动词的过去分词+ that从句（4）It + 不及物动词+ that 从句另注意在主语从句中用来表示惊奇、不相信、惋惜、理应如此等语气时，谓语动词要用虚拟语气“(should) +do”，常用的句型有：It is necessary (important, natural, strange, etc.) that …It is a pity (a shame, no wonder, etc.) that…It is suggested (requested, proposed, desired, etc.) that…It appears that…（似乎……）It happens that…（碰巧……）练习：It worried her a bit ____ her hair was turning grey.A. whileB. thatC. ifD. for2. 宾语从句名词句用作宾语的从句叫宾语从句。
