学习过程：
在句子中起名词作用的句子叫名词性从句(Noun Clauses）。

名词性从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中不同的语法功能，名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。

引导名词性从句的连接词
连接代词：who; whoever； whom; whomever; which； whose ; whosever； what; whatever; which; whichever
连接副词：when; where; how; why; whenever; wherever, however；how构成的短语，（how many/much/Long/soon/often…)
从属连词：that whether; if “是否” as if; as though（“好像”，“似乎”）； because （不充当从句的任何成分）
注意：which表示有明确范围的选择
连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用，在从句中充当从句的成分。

1。

that只起连接主句和从句的作用，在从句中不担任任何成分，本身也没有词义，宾语从句中可省略
2。

引导主语从句、表语从句和同位语从句,that不可省略。

一．主语从句
主语从句是在复合句中充当_______的从句
What he wants to tell us is not clear. 他要跟我们说什么，还不清楚。

It is known to us how he became a writer.
我们都知道他是如何成为一名作家的。

Where the English evening will be held has not yet been announced.
主语从句做题思路：
* 断句方法
1. 含有连接词的：
始——连接词末——第二个谓语动词之前
2. 不含连接词的：
始——空格末——第二个谓语动词之前
二．宾语从句
1. 定义：在句子中起宾语作用的从句叫做宾语从句。

2. 宾语从句分为三类：_____的宾语从句，______的宾语从句和_______的宾语从句。

She did not know what had happened.
动词＋间接宾语＋宾语从句。

例如：She told me that she would accept my invitation.
Our success depends upon how well we can cooperate with one another. 我们的成功取决于我们之间的合作。

I am afraid (that) I’ve made a mistake. 我恐怕我已经犯了一个错误。

三、表语从句
表语从句在复合句中作表语的名词性从句，放在系动词之后，一般结构是“主语＋连系动词＋表语从句”。

可以接表语从句的连系动词有be, look, remain, seem等。

另外，常用的还有the reason is that…和It is because 等结构。

例如：
The fact is that we have lost the game. 事实是我们已经输了这场比赛。

That is why he didn’t come to the meeting. 那就是他为什么不到会的原因。

It looks as if it is going to rain. 看上去天要下雨了。

But the fact remains that we are behind the other classes.
四、同位语从句
同位语从句说明其前面的名词的具体内容。

同位语从句一般跟在某些表示抽象概念的名词后,如 news, idea, information, fact, hope,thought, belief 等，用来说明名词所表示的具体内容，
引导同位语从句的连接词通常有that, whether
连接副词when, where, why, how；
连接代词who，what，whose，which通常不引导同位语从句。

I have no idea when she will be back.
The news that we won the game is exciting.
I have no idea why he was late.
I have no idea whether he'll come or not. 我不知道他是否来。

It is a question how he did it. 那是一个他如何做了此事的问题。
