（that 引导宾语从句时可以省略。

）For example:It worried her a bit that her hair was turning gray.她的头发正在变白，这使她很不安。

that引导主语从句，it 作形式主语，that 不能省略。

That she is a rich woman is known to us all. 众所周知，她是个富有的女人。

这是that 引导主语从句，that 不能省略。

这句话可以改为用it 作形式主语的句型。

请同学们改写：It is known to us all that she is a rich woman.）We didn’t know (that) you had sold your house. 我们不知道你已经把你的房子卖了。

这是that引导宾语从句，that 可以省略。

注意这句话的时态。

二.宾语从句。

1． that 引导的宾语从句: that 没有意义，在口语或非正式文体中常省略例如：I really feel she’s making a mistake. 我的确感到她正犯错误。

James said (that) he was feeling better. 詹姆斯说他感到好些了。

ｔｈａｔ在名词性从句中的用法在复合句中，起名词作用的从句，称为名词性从句。

根据句法功能，名词性从句可以分为主语从句，宾语从句､表语从句和同位语从句。

名词性从句不论是用什么词来引导，从句都必须用陈述句语序，即“引导词+主语+谓语+其它”。

疑问代词或疑问副词充当引导词时，有词汇意义且在从句中担当一定的成分;whether(if只用于宾语从句)作引导词仅有词汇意义且不在句中担当任何成分;如果从句的语法成分完整，主从句语意通顺时一般就该用that来引导。

一､that 用于引导宾语从句时通常可省略，尤其在口语中。

而that引导主语从句､表语从句､同位语从句时一般不能省略。

如: He told me (that) the meeting had been put off.That our volleyball team had beaten theirs pleased every one of us.The problem with building the factory is that we are lack of money.Word came that he has recovered from the bad disease.that引导宾语从句时在以下几种情况中不能省略:1. 宾语从句为多个并列句时，前面分句的that可以省略，但最后一个分句的引导词that不能省略。

He said that if I went there， he would go too. She believes that what the teacher says must be right.3. 主句与宾语从句加入了插入语时。

What 和that 在名词性从句中的用法区别What 和that 都可以引导名词性从句。

一．在引导名词性从句时，从属连词that一般要注意三个不（three nos）：1．不省略（no ellipsis）当从属连词that引导主语从句、表语从句和同位语从句时，that不省略。

Eg. 1) That he was able to come made us happy.(That 引导主语从句不可省略)2)The truth is that I didn’t go there. (that引导表语从句不可省略)3)The news that our team has won is true. (that引导同位语从句不可省略)但在非正式文体中that 引导宾语从句时可以省略，除下列两种情况外：that在宾语从句中不能省略的情况.(1). 在主+谓+it(形式宾语)+宾补+that，从句(真正宾语) 的句型中不省略.Eg: 4) He made it quite clear that he preferred to study English.（that不可以省略）他很明确地说他宁愿学习英语。

(2). 由连词and连接的两个由that引导的宾语从句中, 则第二个宾语从句前的that不省略。

Eg: 5) He told me that he would come and that he would come on time.（第一个That可以省略，但第二个that不可以省略。

)他告诉我他将来而且他将准时来。

2．不作成分（no component）that 在名词性从句中不作任何句子成分。

Eg. 6)Sydney kept his promise that he would always do anything he could for Lucie to make sure of her happiness.（that在句中引导同位语从句，但在句中不作任何成分）7))That you don’t like him is none of my business. (that在句中引导主语从句，但在句中不作任何成分，也不省略）3．没词义（no meaning）that 在名词性从句中没有汉语意思。

名词性从句用法详解一、概说名词性从句，即指性质相当于名词的从句，它包括主语从句、宾语从句、表语从句和同位语从句。

从高考的考查的实际情况来看，名词性从句考得最多的是宾语从句，其次是主语从句，再次是表语从句，而同位语从句则很少考查。

二、名词性从句的一般引导词1.连接词that 引导名词性从句时，只起连接作用，没有任何意思，也不充当句子成分，在宾语从句中可省略，但引导其他名词性从句时通常不省略。

如：I hope (that) you enjoy your holiday. 希望你假期过得好。

That he likes you is very obvious. 很显然他喜欢你。

2.连接词whether 引导名词性从句也不充当句子成分，但有自己的意思，表示“是否”；引导宾语从句时，可换成if，但引导其他名词性从句时不能换成if。

如(from www.yygram )：He asked whether [if] I would show him the way. 他问我是否可以给他带路。

Whether it will do us harm remains to be seen. 是否对我们有害还要看一看。

(引导主语从句，不能用if 代替whether)3.连接代词who(m), whose, which, what 等引导名词性从句时，均有各自的意义，在从句中作主语、宾语、定语等。

如：That’s why she wanted to leave. 这就是她想离开的原因。

When we arrive doesn't matter. 什么时候到没有关系。

Tell me which one you like best. 告诉我你最喜欢哪一个。

4.连接副词when, where, why, how 等引导名词性从句，也各自有自己的意义，在从句中作状语。

如：The question is how we should carry out the plan. 问题是怎样执行这个计划。

that 用法"that" 是一个多功能的词，在不同的语境中可以有不同的用法。

以下是一些常见的用法及详细说明：1. 作为代词使用：- 用于指代前文提到的特定事物或人，相当于"那个"。
