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.

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.

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
D.引导同位语从句时,切不可错用which。例如:
Word has come that some American guests will come to visit our school next week. 有消息说下周将有一些美国客人来我校参观。
____ you have seen both fighters, ____ will win?
A. Since; do you think who B. As; who you think
C. When; whoever D. Since; who do you think
解析：根据上面的讲解，不难知道答案是D。其中do you think是插入成分，其余部分是宾语从句，作think的宾语；由于引导词在从句中作主语，所以要用主格who(不用whom)。
-I drove to Zhuhai for the air show last week.
-Is that ____ you had a few days off?
A. why B. when C. that D. where
解析：答案是A，why引导的从句作表语，同时why在从句中作原因状语。这里之所以选why，而不是when或 where等，唯一的依据便是句子的逻辑含义，及语境。
whatever,whoever,whichever引导名词性从句
一、基本用法概说英语中的-ever 词主要包括 whatever, whoever, whichever, whenever, wherever, however 等，其中可引导名词性从句的主要有 whatever, whoever, whichever等，其中可引导Roman'; mso-ascii-font-family: 'Times New Roman'">。这里所说的名词性从句主要指主语从句和宾语从句，它们通常不用于引导同位语从句，同时也很少用于引导表语从句。如：Whatever he said was right. 无论他说什么都是对的。(引导主语从句)I don’t believe whatever he said. 无论他说什么我都不信。(引导宾语从句)在某些特定的语境中，也可用于引导表语从句。如：
什么是名词性从句
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。

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。

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

）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。
