完成以上四个题目，并分别指出它们是什么从句，从而导出名词性从句的学习。
一．名词性从句的概念： 一个句子在连接词的引导下，在句子中起名词作用的句子叫名词性从句。
二．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。
His job is important. (主语)
What he does is important. (主语从句) &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;
This is his job. (表语)
This is what he does every day. (表语从句)
I don’t like his job. (宾语) &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;
I don’t like what he does every day. (宾语从句) &nbsp; &nbsp;
I don’t know about the man, Mr. White. (同位语)
I don’t know about the fact that he is a teacher. (同位语从句)
得出结论：因此根据它在句中不同的语法功能，名词从句又可分为四类，即：主语从句、宾语从句、表语从句和同位语从句。
三．引导名词性从句的连接词：
1、连接代词：who, whoever, whose, whom, whomever, what, which。有词义，在从句中担任成分，如主语、表语、宾语、或定语等。
l I don’t believe __________ he has achieved so far.
l __________ breaks the law should be punished.
2、连接副词：when, where, why, how。有词义，在从句中担任成分，作状语。
l __________ we will hand in the project will be discussed later.
l Parents are thought to understand __________ important education is to their children’s future.
l The reason __________ he was absent was that he was ill.
3、连接词：that, whether, if, as if, as though。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。
l I don’t care about __________ you have money or not.
l The problem is __________ Tom is able to arrive on time.
l __________ the meeting will be held here is not decided yet.
l It looks __________ it is going to rain.
l The truth is __________he didn’t come for the concert.
l __________ the earth is round is true.
四．名词性从句的类型：
1. 主语从句：在复合句中作主句的主语。连接词有that, whether; who, what ,which; &nbsp;when ,where, how, why 等。 如:
l __________ he is a famous singer is known to us.
l __________ he will go to America is not yet fixed.
l __________ she’s coming or not doesn’t matter too much. &nbsp;
l __________ broke the glass yesterday is not clear.
注意：
1. 为避免主语冗长,句子头重脚轻, 经常用it作形式主语, 主语从句放在后面作真正的主语。
记住以下it作形式主语的句型：
It’s likely / possible / important / necessary / clear that…很可能 / 重要的是… / 必要的是… / 很清楚…
It’s said / reported that…据说/据报道…
It seems / appears / happens that…显然、明显、碰巧…
It’s been announced / declared that…已经通知/宣布…

It’s a pity/a fact /a common knowledge (众所周知）/ a common saying（俗话说）that…

l It remains a question ______ we can get so much money in such a short time.

2. 单个的主语从句作主语时， 谓语动词用句单数形式；如果是两个或两个以上的主语作
主语，谓语动词则视情况而定。
When and where he was born hasn’t been found.
When he was born and where he was born haven’t been found.
When and why the person was murdered is still unknown.
When the person was murdered and why he was murdered are still unknown.

(3) adj + 宾语从句，即“形宾”： that 引导的名词性从句还可以用在一些形容词后面。这种句型一般都用人作主语，所用的形容词都是表示思想状况或感情色彩的形容词，如certain, sure, positive, afraid, convinced, anxious, disappointed, worried, glad, happy, sorry, amazed, surprised, aware, doubtful, confident等等。

他相信他的梦想总有一天会实现的. &nbsp; &nbsp; He believes _________________________ .
b .请告诉我你昨天这个时候在干什么. &nbsp; Please tell me _________________________.

4. 同位语从句：在复合句中起同位语的作用。 一般放在名词 idea ；belief ； fact ； truth ；problem ；news, information; hope; thought; promise等之后, 用以说明或解释前面的名词。常用 that, whether, who, whom, when, where, why, how, which等引导(whose和which 不引导同位语从句)

1. 名词suggestion, advice, order等词后的同位语从句的谓语动词要用should+动词原形, should可省略。

3. 如何判断同位语从句和定语从句?
a. 定语从句是先行词的修饰语，它不涉及先行词的具体内容。定语从句中that不但起连接作用，而且在定语从句中充当一个成分，充当宾语成分时可省略。
b. 同位语从句对中心词的内容作进一步的解释和说明，表明中心词的具体内容。引导同位语从句的that 在同位语从句中不做任何成分，只起连接作用, 无具体含义,且不可省略.
