名词性从句部分
【说明解读】
主语从句、表语从句、宾语从句、同位语从句在复合句中起名词的作用，这四种从句合称名词性从句。它们在主句中充当主语、表语、宾语或同位语，都不能用逗号与主句分开。
（一）引导名词性从句的连接词
1、连接代词：who, who, whom, what, which。有词义，在从句中担任成分，如主语、表语、宾语、或定语等。
2、连接副词：when, where, why, how。有词义，在从句中担任成分，作状语。
3、连接词：that, whether, if, as if。that 无词义，在从句中不担任成分，有时可省略；if (whether), as if虽有词义，但在从句中不担任成分。
注意：连接代词与连接副词在句中不再是疑问句，因而从句中谓语不用疑问式。连接代词与连接副词在从句充当句子成分，连接词whether 和if（是否），as if（好像）在从句中不充当句子成分，只起连接作用。根据句义，如果连接代词与连接副词，whether、if 和as if都用不上时，才用that作连接词（that本身无任何含义）。
■主语从句
1、定义：先找到句子的谓语，主句的谓语前面的从句，叫做主语从句。
Why he left wasn't important.
That she became an artist may have been due to her father's influence.
2、借助形式主语it，主语从句放在后面
①由that引导的主语从句可以放在主语的位置，这时that不可以省略。例如：That prices will go up is certain.
that主语从句放在句首的情况不是很常见，绝大部分主语从句都借助形式主语it，主语从句
放在后面。
It is strange that he knows nothing about it.
It is a pity that he can't swim.
②wh-疑问词引导的主语从句，可以放在句首(第一组)，也可以借助形式主语it(第二组)。
第一组：When he'll be back depends much on the weather.
How it was done was a mystery.
Whether we'll succeed remains to be en.
第二组：It is uncertain whether the game will be held.空气消毒
It's a puzzle how life began.
Is it known where he went？
■宾语从句
1、定义：及物动词(第一组)和介词(第二组)的后面可以接从句做宾语，叫做宾语从句。个人概述
第一组 He asked when we would be in London.
She informed me (that) she was to nd for it the next day.
I'll tell you what I read in today's paper.
第二组 I'll find out whether she's interested in going.
Can you give us a description of what has happened.
2、借助形式宾语it，that引导的宾语从句放在后面。
I've heard it said that you have won a scholarship.
分析：it在句中做形式宾语，said做宾语补足语，that you have won a scholarship是真正的宾语。
She has en to it that all the children are well taken care of.
分析：it在句中做形式宾语，that all the children are well taken care of是真正的宾语。
■表语从句
1、定义：系动词的后面可以接句子做表语，叫做表语从句。
The fact is that she never liked him.蒙蔽的拼音
That is not what I meant.
The question is who is responsible for what has happened.
2、注意：
①The reason Hollywood was a good place for making movies was that the sun shines there every day.
分析：the reason做主语时，表语从句用that引导。
②引导表语从句的that一般不省略。
■同位语从句
1、定义：有些名词的后面可以跟that引导的从句，说明这个名词的内容，这样的从句叫做同位语从句。所以，只有可以有内容的名词才可以接同位语从句，例如：fact，message，idea，possibility，conclusion，thought，news，order，report，rumor等等。
that在从句中不做成分，但是不能省略。
He had the feeling that he would not e her again.
表达技巧有哪些I’ve come to the conclusion that it won't be wi to do so.
2、有时为了保持句子的平衡，同位语从句有时和前面的名词分开。
The rumor spread that a new school would be built here.
分析：that引导的同位语从句修饰the rumor，但是主句The rumor spread太短，如果把后面的同位语从句放在the rumor后面，主语太长，给人头重脚轻的感觉。
3、在少数情况下，名词性从句的其他关联词也可以引导同位语从句。但if不可以引导同位语从句。
You have no idea how worried I was.
I have no idea why she left.
There is some doubt whether John will come on time.
