必备英语中考英语必备英语名词性从句技巧全解及练习题(含答案) 含答案解析一、初中英语名词性从句1．________ the weather will not clear up until next week is bad news for us.A. AsB. IfC. WhetherD. That【答案】 D【解析】【分析】考查主语从句。
句意：直到下周天气才放晴，这对我们来说是坏消息。
此处是that引导的主语从句，that无实义，只其引导作用，故答案为D。
【点评】主语从句属于名词性从句，在名词性从句中，that无实义，只起连接作用，不做句子成分；if/whether起连接作用，不做句子成分，有实义“是否”。
做题时注意看从句是否少成分。
2．It was he said disappointed me.A. that; whatB. what; thatC. that; whichD. which; that【答案】 B【解析】【分析】句意：正是他说的话让我很失望。
这是一个强调句型,"it is/was that..."是固定搭配,"what he said"是被强调部分, 你可以发现去掉"it was that"后, 句子仍然完整。
"what he said"做主语,主语从句中"said"缺宾语用what补足，故选B。
【点评】考查主语从句的强调形式。
3． is known to all is that the earth is smaller than the sun.A. AsB. WhatC. ItD. Which【答案】 B【解析】【分析】句意：众所周知地球比太阳小。
is known to all 是主语从句，从句中缺少主语，因此用what，选B。
【点评】考查名词性从句，本题涉及what引导的主语从句。
(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。

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。

名词性从句在句子中起名词作用的从句叫名词性从句。
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，因此根据它在句中不同的语法功能，名词性从句又可分为主语从句、宾语从句、表语从句、同位语从句。
引导名词性从句的词叫做连接词，包括：1. 连词（在名词性从句中只起连接作用，不作成分）2. 连接代词（在名词性从句中作主语、宾语或表语）3. 连接副词（在名词性从句中作状语）所有的名词性从句的语序都是陈述句语序。
主语从句：是在主句中作主语的从句。
它由连接词引导，通常位于谓语动词之前。
连接词：1. 连词：在从句中不充当任何成分，常见的引导主语从句的连词有that, whether。
That he got the first prize excited him much.他获得一等奖一事使他非常兴奋。
It is doubtful whether we can get there on time.我们能否按时到达那儿还不确定。
1）that引导的主语从句：在从句中不作任何成分，也没有实际意义。
一般情况下that不可省略。
That light travels in straight lines is known to all.众所周知，光沿直线传播。
That you don't like him is none of my business.你不喜欢他不关我的事。
2）whether引导的主语从句：常置于句首，表示“是否”之意；if一般不引导主语从句。
Whether he can finish his task on time is of greatimportance.他是否能按时完成任务非常重要。
Whether you can succeed or not depends on how hard you work at it.你能否成功取决于你努力的程度。
连接代词：在从句中起名词或代词的作用，常作从句的主语、宾语、表语或定语，有具体意义且不能省略。
名词性从句(教师版)
名词性从句名词性从句(Noun Clauses）——在句子中起名词作用的句子。
4类：主语从句、宾语从句、表语从句和同位语从句四种名词性从句都需要一个连接词。
连接词不作任何句子成分，不可省，只引导；that, if, whether连接代词作主语、宾语、表定what, which, who, whom, whose, whatever, whichever, whoever, whomever 连接副词作状语；when, where, why, how, whenever, wherever, however主语从句在句子中作主语。

从句作主语时，谓语动词为单数。
What I do is a kind of legwork.That she wants me to be dead worries me a lot.Why he loves me is unknown.When and where he will eat me is important.It is a pity that he hates me.It remains to be seen whether/if he loves the girl.Tips: 主语从句的that绝对不能省去。
而宾语从句的that可省。
1. It 作形式主语——代替主语从句，主要是为了平衡句子结构。
2. 用it 作形式主语的结构(1) It + be + 名词+ that从句It is a pity/ a shame/ a fact / an honor / common knowledge / no wonder that …(2) It + be + 形容词+ that从句It is necessary/ important/ likely/ certain/ natural / strange that…(3) It + be + 过去分词+ that从句It is told/ reported /said / has been proved that…It is suggested/ advised/ requested/ required/ ordered/ insisted that...(should) + do...(4) It + 不及物动词+ that从句It seems / appears / happe ns / matter / remains to be done that…3. 主语从句不可位于句首的三种情况：（1）if 引导的主语从句不能放在句首。

中考—名词性从句主语从句主语从句的语序主语从句要求使用陈述句语序，而非一般疑问句语序。
如：What surprised me most was that the little girl could play the violin so well.使我感到惊讶的是这个小女孩的小提琴拉得太好了。
连接词的选用（1）that和what的选用that和what都可引导主语从句。
what除起连接作用外，还在名词性从句中充当某些成分，可作从句的主语、宾语或表语。
而that在名词性从句中不充当任何成分，无词义，只起连接词作用。
如：What he wants is a book. 他想要的是一本书。
That light travels in straight lines is known to all. 众所周知，光线沿直线运行。
（2）if和whether的选用引导主语从句，不能用if，只能用whether。
如：Whether we will hold a party in the open air tomorrow depends on the weather. 我们明天是否在户外开晚会要看天气而定。
（3）其它连接代词和副词的选用根据主语从句的具体意义，正确的选择who, which, when, where, why, how等连接词，这些连接词既有疑问含义，又起连接作用，同时在从句中充当各种成分。
如：When we shall hold our sports meet is not decided. 我们何时举行运动会还没有决定。
Who broke the glass yesterday is not clear. 还不清楚昨天谁打破了玻璃。
Which car you will choose to buy makes no difference. 你决定买哪一辆车都不会有任何区别。
（4）whatever / whoever的功用whatever, whoever在主语从句中不含疑问意义。
它引导主语从句，并在从句中作主语、宾语、表语等。
whatever = anything that; whoever = anyone who。
要注意和whatever, whoever引导的让步状语从句的区别。
如：Whoever breaks the law should be punished. （主语从句）（＝Anyone who breaks the law should be punished. ）Whoever breaks the law, he should be punished. （让步状语从句）（＝No matter who breaks the law, he should be punished. ）it构成的主语从句（1）由连词that引导的主语从句，在大多数情况下会放到句子的后面，而用代词it作形式主语。
谓语是seem, appear, be certain, be a pity, be a wonder, be one's hope, be likely等词或短语时。
It is well-known that the earth moves around the sun. 众所周知，地球围绕太阳转。
需要注意的是，it作形式主语代替主语从句时，要注意和as引导的定语从句的区别。
试比较：It was reported that the US was under the terrorist attack. （主语从句，有that，无逗号）As was reported, the US was under the terrorist attack. （定语从句，无that，有逗号）上两句意为“据报道，美国遭到恐怖分子的袭击”。
用于It is suggested / required / ordered / demanded that...句型中,动词为表示命令、建议、要求等意义的词。
主语从句应使用虚拟语气,谓语动词用"should + 动词原形",should可以省略。
例如:It is suggested that you (should) spend more time in studying English. 你应该花更多的时间学习英语。
（2）常见用it作形式主语的复合句结构1.It is a fact （a good idea / a pity / a shame / no wonder / good news…）that…如：It's a pity that you missed the film. 你没有看那部电影真是太遗憾了。
2. It is necessary （clear / true / strange/ important /wonderful / possible / likely…）that…需要注意的是，这类主语从句中，谓语动词很多为“（should）＋动词原形”，即要用虚拟语气。
如：It is necessary that you （should）master the computer. 你很有必要掌握电脑。
It is important that a student learn English well. 学生学好英语很重要。
It's clear that they badly need help. 很明显，他们急需援助。
