高考英语复习 名词性从句讲解
名词性从句一、名词性从句与简单句的区别在英文中，名词或名词短语主要充当四种句子成分：主语、宾语、表语和同位语。
如果把句子当作名词来用，分别充当另一句话的主语、宾语、表语或同位语，于是便构成了四种从句：主语从句、宾语从句、表语从句和同位语从句。
因为这四种从句在本质上相当于名词的作用，所以将其统称为名词性从句。
请看下表：在英语中，相当于名词作用的句子有三类，陈述句、一般疑问句以及特殊疑问句。
因此，名词从句就是用三种句子来分别充当另外一个句子的四种句子成分，者就构成了名词从句的本质特征。
但是，这三种句子不是直接放在另一个句子中作成分，而是要作各种变化调整。
接下来将具体讨论。
二、陈述句作句子成分1. 要在陈述句句首加上t hat用”that+陈述句”这一结构分别充当另一个句子的四种成分。
2.为什么要加that?对于陈述句，为什么要在其句首加that 后才能用它作成分呢？而为什么在宾语从句中that 又可以省去呢？因为在英文中，句子的核心意思主要是靠谓语部分来表达，一个句子只表达一个核心意思，也就是只能有一个谓语部分。
而添加that，相当于一个“指路牌”，能够帮助我们指明段句的方向，而不至于造成歧义。
而对于宾语从句，主句的谓语已经出现，后面所接的成分自然是谓语，所以在不会影响句子的意思下，是可以把that 省去的。
三、一般疑问句作句子成分1.用w hether 或if 引导先将疑问句的倒装语序变成陈述句语序(即主语放在谓语的前面)，并在句首加上whether 或if（if 只用在宾语从句中）来引导，以保留原句的疑问意义。
即“whether+陈述句”2. if 还是 whether?1)if 一般只用于引导宾语从句，而 whether 可引导宾语从句在 内的其他名词从句。
IF he comes or not makes no difference. 成 Whether he comes or not makes no difference.2)if 不和 or not 直接连用，即一般不说 if or not, 但可以说 if...or not 。
高中英语高考名词性从句专项复习(知识点+易错点+练习题)
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。

宾语从句中that不可省略的情况
宾语从句前有插入语

高考复习：名词性从句
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。
高考英语名词性从句考点归纳
名词性从句名词性从句指在复合句中起名词作用的从句，它在句子中可作主语、宾语、表语或同位语。
名词性从句既是中学英语教学的重点，也是高考考查的热点。
一、名词性从句的分类名词性从句包括主语从句、宾语从句、表语从句和同位语从句。
其连接词有that, if, whether；连接代词who, what, which；连接副词when, where, how, why等。
考查热点一：对主语从句的考查主语从句在复合句中充当主语，它可以放在主句谓语动词之前。
但为了保持句子平衡，多数情况下可用it作形式主语，而把主语从句置于句尾。
考查热点二：对宾语从句的考查宾语从句在句子中作及物动词或介词的宾语。
如果主句的谓语动词是及物动make, find, see, think等，则把宾语从句置于宾语补足语之后，用it作形式宾语。
另外，某些作表语的形容词，如sure, happy, glad, certain 等之后也可以带宾语从句。
考查热点三：对表语从句的考查表语从句在句子中作表语，位于主句中的系动词之后。
一、什么是表语（predicative）在形式上，位于系动词后的就是表语。
从含义上讲，表语是回答主语“是什么”或“怎么样”的语法成分。
即是指“是”字句“是”字后面的成分。
表语就是起表述作用的句子成分。
它修饰的是主语。
表语是用来说明主语的身份、性质、品性、特征和状态的。
表语须和连系动词一起构成句子的复合谓语。
表语常由名词、形容词、副词、介词短语、不定式、动词的-ing、动词的-ed、从句来充当，它常位于连系动词（be, become, appear, seem等）之后。
Albert Einstein was a famous professor of physics.二、不定式、动名词与分词作表语的区别不定式和动名词作表语相当于一个名词作表语，含义是回答主语“是什么”；分词作表语相当于形容词作表语，含义是回答主语“怎么样”。

表语从句
• 表语从句 • 表语从句位于连系动词后,有时用as if、though引
导。 • 其基本结构为:主语 + 系动词 + that从句。 • 1. be, look, remain, 等系动词后均可跟表语从句：
• My suggestion is that we should go shopping. • 2. as if 也可引导表语从句。
语
• That he finished writing the composition in such a short time surprised us all.
• Whether we will go for an outing tomorrow remains unknown.
• Who will be our monitor hasn't been decided yet.
see______use a new invention can be of to human life.
A．whose
B．what
C．which
D．that
解析：考查名词性从句。句意：让人们明白一项新发明对
人类生活有什么用途并不总是容易的。该从句缺少定语，
变为陈述语序为：A new invention can be of what use to
名词性从句
1. 名词性从句的种类
• 名词性从句包括: • 主语从句、宾语从句、表语从句、同位语从句。 • It matters much whether the headmaster supports
our activity. • 校长是否支持我们的活动很重要。 • 主语从句（形式主语it)

human life.本题易误选为C项，which表示“在某个范围
内的选择”，意为“哪个，哪些”。本句并未涉及范围，
故答案为B项。

that's ______I'd do if I had the money.
• When the news came that the war broke out, he decided to serve in the army.(摘自2011辽宁高考)
• 当战争爆发的消息传来时，他决定去参军.
• 同位语从句
• 同位语从句 • 在句中作同位语，它一般要放在主句中某些名词
A．why
B．when
C．which
D．what
解析：考查表语从句。句意：我想自己做生意——那是我
如果有钱就会做的事情。从句中的do 是及物动词，缺少宾
语，所以将A 和B 排除，which 引导名词性从句时，意为
“哪个，哪些”，一般用于有一定范围可供选择的情况。
不合逻辑，故用what。
• 2. 为了防止句子头重脚轻，通常把形式主语it放 在主语位置，真正主语搁置于句末
