高考语法填空抢分热点之名词性从句一、考点精讲名词性从句的引导词：1.that 无词义，只起引导作用，可以省略，但两个或两个以上that引导的宾语从句并列时，从第二个开始that不能省略。
2.what引导名词性从句，既起引导作用，又在从句中作一个成分，起双重作用，不能省略。
3.连词whether“是否”，可以引导主语从句、表语从句、介词之后的宾语从句以及同位语从句，而if“是否”只能引导动词后面的宾语从句。
4.引导名词性从句的连接副词有when、where、how、why，在判断名词性从句引导词的使用时，如果句子缺成分，缺什么，补什么。
二、高考题经典解读1.______(56) is so breathtaking about the experience is the out-of-this-world scenes.【答案】What【解析】考查主语从句。
句意：这段经历最让人激动的是那些脱离世界的场景。
设空处无提示词，应考虑填冠词、介词、连接词，又因为空格在句首，后面是谓语动词is，这里应该填一个连接词，引导主语从句，从句缺少引导词和主语，且指物，所以连接代词What符合语境，其双重作用。
位于句首，首字母用大写。
故答为What。
2.While they are rare north of 88℃，there is evidence ______ they range all the way across the Arctic，and as far south as James Bay in Canada.【答案】that【解析】考查同位语从句。
句意：虽然它们在88℃以北很少见，但有证据表明，它们一直分布在北极，南至加拿大的詹姆斯湾。
该句是含让步状语从句的复合句，主句部分是there be句型，设空处填that，引导同位语从句，说明evidence的具体内容。
故答案为that。
3.Research suggests an increase in voice is a signal ________ someone is lying.【答案】that【解析】考查同位语从句。
高考英语名词性从句知识点一、that从句1、主语从句that从句作主语时，常用it作形式主语，常见的句型有：It+be+形容词(obvious, true, natural, surprising, good, wonderful, funny, possible, likely, certain, probable, etc. ) + that 从句It+be+名词词组(no wonder, an honor, a good thing, a pity, no surprise, etc. ) + that 从句It+be+过去分词(said, reported, thought, expected, decided, announced, arranged,etc. ) + that 从句that可以省略，但that从句位于句首时，that不能省略。
2、宾语从句(1)常见的可以接that从句作宾语的动词有see, say, know, imagine, discover, believe, tell, show, think, consider, be sure, be afraid 等。
在可以接复合宾语的动词之后,如think, make, consider等，可以用it作形式宾语。
(2)That从句一般不能充当介词宾语，偶尔可作except, in的宾语。
3、表语从句(that不可省略)4、同位语从句连词that引导同位语从句时，应在某些抽象名词之后,如：fact, hope, desire, thought, suggestion, idea, news, problem, possibility 等，对前面的名词起补充说明的作用，that 在从句中不担当任何成分，不能省略。
二、whether/if 从句1＞在表语从句和同位语从句中，只能用whether不能用if；当主语从句放于句首时，只能用whether不用if；当it作形式主语，主语从句放在句末时用whether或if均可；discuss后引导宾语从句时，必须用whether。

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。
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
一、连词分类：
引导名词性从句的连接词可分为三类：
连接词：that,（无成分，无含义）whether, if （无成分，有含义）
连接代词：what, who, whom, which, whose, ~+ever, no matter + ~.（有成分和含义）连接副词：when, where, how, why（有成分和含义）
二、分类讲解
1. 主语从句
作句子主语的从句叫主语从句。
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。
有时为避免句子头重脚轻，常用形式主语it放于句首，而把主语从句置于句末。
It is necessary to read English everyday.
It is said that we are going to have a holiday very soon.
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 (request ed, proposed, desired, etc.) that…
2. 宾语从句
1. 由连接词that引导的宾语从句
由连接词that引导宾语从句时，that在句中不担任任何成分，在口语或非正式的文体中常被省去，但如从句是并列句时,第二个分句前的that不可省。
例如：
He has told me that he will go to Shanghai tomorrow. 他已经告诉我他明天要去上海。
We must never think (that) we are good in everything while others are good in nothing.
我们决不能认为自己什么都好，别人什么都不好。
注意：在demand、order、suggest、decide、insist, desire, demand, request, command等表示要求、命令、建议、决定等意义的动词后，宾语从句常用“（should）+ 动词原形”。
I insist that she (should) do her work alone. 我坚持要她自己工作。
The commander ordered that troops (should) set off at once. 司令员命令部队马上出发。
2. 用who, whom, which, whose, what, when, where, why, how, whoever, whatever, whichever等关联词引导的宾语从句相当于特殊疑问句，应注意句子语序要用陈述语序。
I want to know what he has told you. 我想知道他告诉了你什么。
She always thinks of how she can work well. 她总是在想怎样能把工作做好。
She will give whoever needs help a support. 凡需要帮助的人，她都会给予支持。
3. 用whether或if引导的宾语从句，其主语和谓语的顺序也不能颠倒，仍保持陈述句语序。
此外，下列情况只能用whether，不用if：
a. 引导主语从句并在句首时；
b. 引导表语从句时；c . 引导从句作介词宾语时；d. 从句后有“or not”时；e. 后接动词不定式时。
Whether there is life on the moon is an interesting question.
月球上有没有生命是个有趣的问题。
Everything depends on whether we have enough money. 一切要看我们是否有足够的钱。
4. think, believe, imagine, suppose等等动词引起的否定性宾语从句中，要把上述主句中的动词变为否定式。
即将从句中的否定形式移到主句中。
We don’t think you are here. 我们认为你不在这。
I don’t believe he will do so. 我相信他不会这样做。
3. 表语从句
其基本结构为：主语+ 系动词+ that从句。
例如：
The fact is that we have lost the game. 事实是我们已经输了这场比赛。
That is why he didn’t come to the meeting. 那就是他为什么不到会的原因。
It looks as if it is going to rain. 看上去天要下雨了。
需要注意的，当主语是reason时，表语从句要用that引导而不是because。
The reason why he was late was that he missed the train by one minute this morning
4. 同位语从句
同位语从句说明其前面的名词的具体内容。
同位语从句通常由that引导，可用于同位语从句的名词有advice、demand、doubt、fact、hope、idea、information、message、news、order、problem、promise、question、request、suggestion、truth、wish、word等。
The news that we won the game is exciting.我们赢得这场比赛的消息令人激动。
I have no idea when he will come back home. 我不知道他什么时候回来。
The thought came to him that Mary had probably fallen ill. 他想到可能玛丽生病了。
同位语从句和定语从句的区别：
that作为关系代词，可以引导定语从句，充当句子成分，在从句中作宾语时可以省略that引导同位语从句时，起连词作用，没实际意义，不充当句子成分，一般不能省略。
试比较下面两个例句:
I had no idea that you were here．（that引导同位语从句，不能省略）
Have you got the idea（that）this book gives you of life in ancient Greece？（that引导定语从句，作宾语，可以省略）。
