名词性从句是英语语法中的重要组成部分，它在句子中充当名词的作用，可以作主语、宾语、表语和同位语。掌握名词性从句的用法，对于理解和运用英语至关重要。以下将通过大量的例句，详细讲解主语从句、宾语从句、表语从句和同位语从句的用法，并分析其特点。

一、主语从句

主语从句在句中作主语，通常位于句首。引导主语从句的词有：that, what, whether, who, whom, which, whose, whatever, whoever, whomever, whichever等。为了避免句子头重脚轻，常用it作形式主语，而将真正的主语从句后置。

例句：
That he is honest is known to all. (他很诚实，这是众所周知的。)
What he said is very important. (他所说的话很重要。)
Whether he will come is still uncertain. (他是否会来还不确定。)
Who will win the game is unknown. (谁会赢得比赛还不知道。)
It is a pity that he missed the meeting. (他错过了会议，真可惜。)
It is uncertain when he will arrive. (他什么时候到还不确定。)
It matters little what they think of me. (他们怎么看我，这无关紧要。)

二、宾语从句

宾语从句在句中作宾语，可以是动词的宾语，也可以是介词的宾语。引导宾语从句的词与主语从句相同。

例句：
I know that he is a good student. (我知道他是一个好学生。)
He asked what I was doing. (他问我正在做什么。)
She wondered whether he would come. (她想知道他是否会来。)
We believe who he is. (我们相信他是谁。)
He is interested in what you said. (他对你说的话感兴趣。)
I'm not sure what time it is. (我不确定现在几点了。)
Please tell me whether you will attend the meeting. (请告诉我你是否会参加会议。)

三、表语从句

表语从句在句中作表语，位于系动词之后，说明主语的性质、状态或内容。引导表语从句的词与主语从句相同，但that通常不能省略。

例句：
The problem is that we don't have enough money. (问题是我们没有足够的钱。)
The question is whether we should go or not. (问题是我们是否应该去。)
That's what I want to know. (那就是我想知道的。)
The reason is that he was ill. (原因是他病了。)
My suggestion is that we should start early. (我的建议是我们应该早点出发。)
This is where I live. (这就是我住的地方。)

四、同位语从句

同位语从句在句中作同位语，对前面的名词进行解释说明，通常位于名词之后。引导同位语从句的词主要是that，有时也可用whether, who, what等。that在同位语从句中通常不能省略。

例句：
The news that he had won the prize made us happy. (他赢得了奖的消息使我们很高兴。)
The fact that the earth is round is known to all. (地球是圆的这个事实是众所周知的。)
I have no idea whether he will come. (我不知道他是否会来。)
