Part One

概念及功能




一．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．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 words were very important. (主语)
What he said was very important. (主语)
This is his job. (表语)
This is what he does every day. (表语)
I don’t like his job. (宾语)
I don’t like what he does every day. (宾语)
I don’t know about the fact that he is a teacher. (同位语)
I don’t know about the man, Mr. White. (同位语)
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。

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。
? I don’t believe __________ he has achieved so far.
? __________ 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。
? __________ we will hand in the project will be discussed later.
? Parents are thought to understand __________ important education is to their children’s future.
? 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。

Part Three


名词性从句的分类


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;
when ,where, how, why 等。 如:
? __________ he is a famous singer is known to us.
? __________ he will go to America is not yet fixed.
? __________ she’s coming or not doesn’t matter too much.
? __________ 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 no wonder that…并不奇怪无疑…
It’s a pitya fact a common knowledge (众所周知） a common saying（俗话说）that…
? It worried her a bit ______ her hair was turning grey.
? It remains a question ______ we can get so much money in such a short time.
? It is known to us ______ where there is pollution, there is harm.
2. 单个的主语从句作主语时， 谓语动词用单数形式；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 we will hold the party hasn’t been found.
When we will hold the party and where we will hold the party haven’t been found.

______I can pay back the help that people give me makes me very happy.

2. 表语从句：在复合句中作主句的表语。引导词有连词that , whether, who, what, which, whose;
when, where, how, why, because; as if, as though; 等。如:
? The problem is _________ we didn’t get in touch with him.
? This is _________ Henry solved the problem.
? His suggestion is _________ we (should) finish the work at once.
? It looked _________ it was going to rain.
? The reason _________ we didn't trust him is _________ he has often lied．
注意：
1. 如果句子的主语是suggestion, advice, order, demand, proposal等名词时,后面引导的表语从句
用should+动词原形,should可省略。
他的建议是我们应该马上完成工作. His suggestion is that we (should) finish the work at once.
2. The reason is that … …的理由是，… 的原因是…

3.宾语从句：在复合句中作主句的宾语。 引导词有连词that , whether, if; who, whom, whose,
what ,which; when ,where, how, why 等。如:
(1) V + 宾语从句，即“动宾”：
We believe that he is honest. I asked if they had a cheap suit. Can you tell me which dictionary is
hers? I really don’t know what he is doing.

? --- Don’t you believe me? --- ______, I will believe ______ you say.

A. why B. what C. who D. that
(3) adj + 宾语从句，即“形宾”：
I’m sure that my brother will love the jacket. I am glad that you can come and help me.
不能误将”It + be + adj + that” 的主语从句当成宾语从句.
如：It is necessary that we should learn English well.
注意：
(1) whether与if都可以引导宾语从句，常可互换。但下面情况不能互换。
①用if 会引起误解，就要用whether。
Please let me know whether you want to go.（如果把whether改成if，容易当成条件句理解）
②宾语从句中的whether 与or not直接连用，就不能换成if；不直接连用，可换成if。

I don’t know whether or not the report is true.
I don’t know whetherif the report is true or not.
③介词后的宾语从句要用whether引导。
④whether 可与不定式连用，构成whether to do结构。
wheth er也可引导主语从句、表语从句、同位语从句，以上均不能换成if。但引导条件从句时，
只能用if ，而不能用whether。
They don’t know whether to go there.
Please come to see me if you have time.

(2) 如果宾语从句是由that 引导，and或but连接的两个或两个以上的并列的宾语从句, 那么

He said ( that ) the text was very difficult and that we had to work hard at it.
My deskmate told me (that ) he watched a football match last night, but that it was very
discouraging.
如果宾语从句后 还有宾语补足语，就用it作形式宾语，将宾语从句后置，并且that不可以省
略.
He has made it clear that he will win the game.
I find it necessary that we should learn English well.
We find it necessary that we practice spoken English every day.

(3) 表示“建议，命令，要求”的宾语从句，如advise, suggest, order, request, require, demand 等，
从句用虚拟语气，即should+动词原形,should可省略。

(4) 在“主语+ believethinksupposeknowexpect”的结构中，其否定形式要用否定 转移，即主句
否定，从句肯定。
I don’t think he will come.
I don’t think I’ll trouble you again.

I don’t expect that they will get married soon.
(5) 宾语从句的时态呼应：
a. 如果主句时态是一般现在时或将来时,从句谓语可根据句意需要而选用任一种时态.
他相信他的梦想总有一天会实现的. He believes _________________________ .
b .请告诉我你昨天这个时候在干什么. 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)

? We heard the news ______ our team had won.
? The problem ______ it is right or wrong has not yet been decided.

? There’s a feeling in me ______we’ll never know what a UFO is-----not ever.
? It remains a question ______ we can get so much money in such a short time.
? Danby left word with my secretary ______ he would call again in the afternoon.

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.
