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。

名词性从句初中名词性从句的三种类型
名词性从句初中名词性从句的三种类型名词性从句是英语语法中的一个重要概念，它在句子结构中充当名词的作用。
初中阶段，学生们需要掌握名词性从句的三种基本类型：主语从句、宾语从句和表语从句。
本文将详细介绍这三种类型的名词性从句，并给出一些例子来帮助读者更好地理解和应用。
一、主语从句主语从句在句子中作为主语出现，它通常由一个连接词引导，如that、whether或者疑问词（who、what、when、where、why、how等）。
主语从句的特点是：1. 后置位置：主语从句通常出现在句子主语的后面。
2. 单复数取决于从句的谓语动词：如果主语从句表达的是一个单数概念，那么谓语动词也使用单数形式；如果主语从句表达的是一个复数概念，那么谓语动词则使用复数形式。
下面是一些主语从句的例子：1. Whether he will come to the party is still uncertain.（他是否会来参加派对还不确定。
）2. What she said is true.（她说的是真的。
）3. When we will have the meeting hasn't been decided yet.（我们何时开会还未决定。
）二、宾语从句宾语从句在句子中作为动词的宾语出现，它通常由一个连接词引导，如that、whether或者疑问词。
宾语从句的特点是：1. 通常出现在及物动词或介词后面，作为动词的宾语。
2. 通常用陈述语序（即主语+谓语），而不是疑问句语序。
下面是一些宾语从句的例子：1. He doesn't know what he should do next.（他不知道接下来该怎么办。
）2. I wonder if they have arrived.（我想知道是否他们已经到达。
）3. She asked me where I had been.（她问我去了哪里。
）三、表语从句表语从句在句子中作为主语或宾语的补足语出现，通常由一个连接词引导，如that、whether或者疑问词。
