陈述句 一般疑问句 特殊疑问句
一、连词（引导词） 1. 当宾语从句是陈述句时（包括肯定句和 否定句），连词由 that 引导，因为 that 在从 句中不作任何成分，也没有任何具体意思， 因此在口语或非正式文体中常省略。

Object Clauses 宾语从句
1. I
主语

宾语从句的注意事项
在主句为动词 be 加某些形容词（如 sorry,
sure, afraid, glad等）作表语时，后面所跟
的省略that的从句也可算是宾语从句。
I’m sorry (that) I don’t know .

I’m afraid (that) he won’t pass the exam .
tomorrow.

连接词+主语+谓语+其他成分。
She says (that) she won’t take part in the sports meeting next Sunday. Jim thought (that) the train was like a big moving party.
宾语从句中的连接词that在以下三种情况下 不能省略： （1）当that 从句与另一名词性从句并列作宾语时， 第二个that不能省； （2）当that从句作介词宾语时，that不可省掉。 （3）用it做形式宾语的宾语从句。 Everyone knew what happened and that she was worried. The reason lies in that she works harder than the others do. I think it necessary that you should read English aloud.

初中英语中的名词性从句详解

本文将详细解析初中英语中的名词性从句。
一、什么是名词性从句名词性从句是由一个引导词引导的从句，它在句子中充当名词的角色。

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 。
