名词性从句
语序：陈述语序
在句中充当主语的从句称为主语 从句。英语中主语从句的句型可分 为两大类： 直接将主语从句放在主语位置上； 用it作形式主语，将真正的主语从 句后移，放在其他成分后。
让我们先说说第一类吧！
一、连接词（只起连接作用，在从句中不充当句子成分）
that：无词义。 e.g.: 他赢得比赛一事在我国引起巨大轰动。 That he won the game made a tremendous stir in our country. whether：“是否”。可单独使用，也可与or或or not连用。 e.g.: 我们明天是否能去春游取决于天气。 Whether we can go for a spring outing depends on the weather. 他们是否会来还未告诉我们。 Whether they will come has not been told to us.
四、主语从句与主谓一致
一个从句作主语时，谓语动词通常用单数形式， 特别是用it作形式主语的句型。 e.g.: Whether this kind of chemicals is better has not been tried.
当what引导主从，应遵循意义一致原则，谓语动 词选用相应形式。表语是复数时，谓语动词用复数 形式。 e.g.: What we do willingly is easy. What they were searching for were the missing gems.

名词性从句
名词性从句1.名词性从句的定义名词性从句是起名词作用的从句，这些从句可以作为一个整体来看，其作用就相当于一个名词，在复合句中作主语，宾语，表语和同位语。
名词性从句包括主语从句，表语从句，宾语从句，同位语从句四种。
2.名词性从句的连接词名词性从句通常由一个连接词和主句相连。
连接词很重要，它既是联系主句的纽带，又是从句的标志，通过连接词，我们可以辨认不同从句的性质。
一．从属连接词（在从句中不充当任何成分，只起到连接从句的功能）A．that 只是引导名词性从句，本身并没有实际意义，在从句中不充当任何句子成分。
That he will come to the meeting is certain.(主语从句)The fact remains that we are behind the other group.(同位语从句)B．if和whether具有“是否”的意义，但是whether比较正式，在口语中人们经常if, if 和whether在名词性从句中尽管不充当任何的成分，但不可以省略。
C．whether不能替代if的情况1.if只能引导宾语从句（做介词宾语的情况除外），而whether 可以引导所有的名词性从句。
She asked if/ whether that was enough.Whether the football match will be played depends on the whether.The question is whether we can arrive there on bus.2.whether引导宾语从句做介词的宾语，if没有这种用法It depends on whether it will be fine.3.whether后紧跟不定式He was wondering whether to go home.4.or not 可直接跟在whether后面，但不可以直接跟在if后面。

名词性从句的三种类型及例句解析
名词性从句的三种类型及例句解析名词性从句是指在一个句子中充当名词的从句。
它可以作主语、宾语、表语和同位语等，并能够起到连接子句与主句的作用。
在英语语法中，有三种主要类型的名词性从句：宾语从句、主语从句和表语从句。
本文将详细解析这三种类型，并举例说明其用法。
一、宾语从句宾语从句作为一个整体出现在主句中的动词后面，充当主句的宾语。
它常常引导由that、whether/if、wh-疑问词引导的从句。
下面是一些例句：1. 主句：He asked me a question.宾语从句：He asked me whether I had finished my homework.解析：宾语从句"whether I had finished my homework"作为动词"ask"的宾语，表达了一个疑问。
2. 主句：She doesn't know the answer.宾语从句：She doesn't know what the answer is.解析：宾语从句"what the answer is"作为动词"know"的宾语，表示对答案的不知道。
3. 主句：They wonder if he will come to the party.宾语从句：They wonder if/whether he will come to the party.解析：宾语从句"if/whether he will come to the party"作为动词"wonder"的宾语，表达了对他是否会来参加派对的疑问。
二、主语从句主语从句作为一个整体出现在句子的最前面，充当主句的主语。
它通常由that引导，也可以由wh-疑问词引导。
以下是一些例句：1. 主句：It is important to learn a foreign language.主语从句：That she is a hardworking student is important.解析：主语从句"That she is a hardworking student"作为句子的主语，强调了她是一个勤奋的学生的重要性。
名词性从句
名词性从句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。
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。
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主语从句的例句：That he was won the prize is true.It is true that he has won the prize.What he said at the meeting is right,Whether he will come or not is unknown.Whoever comes will be welcome. Why he did it is not quite clear.2. 宾语从句名词句用作宾语的从句叫宾语从句。

什么是名词性从句？名词性从句（Noun Clauses）是一个在句子中充当名词的从句。
它可以在句子中担任主语、宾语、表语或补语的角色。
名词性从句通常由连词引导，例如that, whether, if, who, whom, whose, what, which, when, where, why等。
以下是名词性从句在不同角色中的示例：1. 主语（Subject）：- What she said surprised me.（她所说的让我感到惊讶。

）2. 宾语（Object）：- I know that he is coming.（我知道他要来。

）4. 补语（Complement）：- The important thing is what you do next.（重要的是你接下来要做什么。
）- His goal is to become a doctor.（他的目标是成为一名医生。
）名词性从句的使用可以使句子更加丰富和灵活，它可以替代一个独立的名词，并在句子中承担相应的语法角色。
名词性从句可以用于各种不同的语境，包括陈述句、疑问句和感叹句等。
需要注意的是，名词性从句的引导词可以根据从句的具体内容和功能而有所不同。
因此，在使用名词性从句时，我们需要根据语境和句子的需要选择适当的引导词。
了解和掌握名词性从句的概念和用法，可以帮助我们在英语表达中更加灵活和准确地使用不同类型的从句。
名词性从句的三种类型与用法
名词性从句的三种类型与用法名词性从句指的是在句子中充当名词的从句。
在英语中，名词性从句有三种类型，分别是主语从句、宾语从句和表语从句。
它们在句子中扮演不同的角色，起到连接主句与从句的作用。
本文将详细介绍这三种名词性从句的类型与用法。
一、主语从句主语从句在句子中充当主语的角色。
它常常以“that”开头，但也可以用“whether/if”引导。
主语从句位于主句之前，因此有时需要使用it作为形式主语来引导整个句子。
例如：1. That she is talented is obvious.2. Whether he will come to the party is uncertain.在上面的例句中，“that she is talented”和“whether he will come to the party”分别是主语从句。
它们在句子中起到了名词的作用，充当主语。
二、宾语从句宾语从句在句子中充当宾语的角色。
宾语从句通常出现在及物动词、介词或系动词之后。
引导宾语从句的词语包括“that, whether/if, who, whom, whose, which”等。
例如：1. He said that he would come to the party.2. I don't know if she has finished her work.在以上例句中，“that he would come to the party”和“if she has finished her work”分别是宾语从句。
它们充当了及物动词“said”和“know”的宾语。
三、表语从句表语从句在句子中充当表语的角色，说明主语的身份、特征、状态或性质。
表语从句通常以“that, whether/if, who, whom, whose, which”等词语引导。
例如：1. My belief is that honesty is the best policy.2. It is unclear whether he can pass the exam.在上述例句中，“that honesty is the best policy”和“whether he can pass the exam”分别是表语从句。

二、It+be动词+形容词+that从句 It is clear that…显然…… It is possible that…很可能…… It is likely that…很可能…… It is natural that…很自然…… It is certain that…可以相信…… It is strange that…奇怪的是…… It is fortunate that…幸运的是…… It is necessary that…有必要……

三、It+be动词+名词短语+that从句 It is a pity that…可惜的是…… It is a fact that…事实是…… It is good news that… ……真是太好了。 It is a good thing that… ……真是件好事。 It is no wonder that… 难怪…… It is a shame that…遗憾的是……/……真是太不像话了 It is an honor that…真荣幸…… It is common knowledge that… ……是常识。 It is my belief that … 我相信…… It is a miracle that… ……真是奇迹。

（五）同位语从句 同位语从句在句中作某一名词的同位语， 一般位于该名词（如：news, fact, idea, suggestion, promise等）之后，说明该名词 的具体内容。 e.g. I have no idea when he will be back. The fact that he had not said anything surprised everybody.
3.Wh-ever和 no matter Wh-的区别: Wh-ever:既能引导名词性从句, 又能引导让 步状语从句. no matter Wh-:只能引导让步状语从句. e.g. Whoever breaks the rule shoud be punished. He won’t believe whatever I said. Whatever I said, he won’t believe me. =No matter what I said, he won’t believe me.
注意：连接代词与连接副词在句中不再是疑问句，因而从句中 谓语不用疑问式。连接代词与连接副词在从句充当句子成分， 连接词whether 和if（是否），as if（好象）在从句中不充当句 子成分，只起连接作用。根据句义，如果连接代词与连接副词， whether、if 和as if都用不上时，才用that作连接词（that本身无 任何含义）。
2. that引导的定语从句和同位语从句的区别: that在同位语从句中,不担任成分,只起连接 作用. that在定语从句中，担任成分,可作主语,宾 语和表语 e.g.The news that we heard on the radio is not true. The news that our class won the match was exciting.
