英语that从句

That可以引导定语从句  、名词性从句  、状语从句  。

that是表语从句。

技巧：判断是什么从句，就是看从句在整个句子中做什么成分，显然是在整个句子“It was exactly

某某”中做was的表语。当然，是what引导从句，在从句中充当宾语成分，为need的宾语。

that引导的从句如下：

1、主语从句that从句作主语时，常用it作形式主语，常见的句型有：It+be+形容词（obvious, true, natural, surprising,good,wonderful,funny,possible,likely,certain,probable,etc.)+that从句。

2、宾语从句常见的可以接that从句作宾语的动词有see, say, know, imagine, discover, believe, tell, show, think, consider, be sure, be afraid等。在可以接复合宾语的动词之后，如think, make, consider等，可以用it作形式宾语。

3、同位语从句。连词that引导同位语从句时，应在某些抽象名词之后，如：fact, hope, desire, thought, suggestion, idea, news, problem, possibility等，对前面的名词起补充说明的作用，that在从句中不担当任何成分，不能省略。

4、名词性从句。名词性从句包括：主语从句，宾语从句，表语从句和同位语从句。在以上名词性从句中，只有在宾语从句中才可以省略；其他情况下，都不可省略。

That可以引导名词性从句，状语从句和强调句。

It was exactly what I needed是表语从句，是"主句+表语从句"构成的主从复合句,其中表语是由"what"引导的是表语从句来充当.这里"it" 作代词,当然"it"也可替代后面的名词从句放在句首作形式主语,但这里却不成。

that名词性从句。

①引导宾语从句。及物动词后的引导词that可省略。

I didn't expect (that) he could win the championship.

The teacher pointed out that Tom was not working hard enough.

② 引导主语从句。通常采用it作形式主语的句型。

That the earth goes around the sun is known to everyone.

（It is known to everyone that the earth goes around the sun.）

③引导表语从句。

The trouble is that we are short of money.

④引导同位语从句。

引导同位语从句的that和引导定语从句的that是不同的。前者只起语法作用，在从句中不作任何成分；而后者在定语从句中作主语、宾语或表语。举例说明：

The news that he resigned from office surprised us.

The idea that he holds is very common nowadays on campus.
