名词性从句讲义
名词性从句学案
一、定义：在复合句中相当于一个名词，做主语、宾语、表语、同位语的从句。
二、引导词：
1. 连词: that , if, whether, as if
2. 连接代词: who , what, which, whose, whom以及wh+ever
3. 连接副词: when, where, why, because, how
三、引导词的作用：
1. 连词只有连接的功能，而不在从句中充当句子成分。
2. 连接代词和连接副词不但有连接的功能，同时还要在从句中充当特定的句子成分，主
语、宾语、表语、定语、状语。
主 语 从 句
基本概念
1． 定义：在复合句中作句子主语的从句叫做主语从句。
2． 构成：关联词+简单句
3． 引导主语从句的关联词有三类：
连词that、whether;
疑问代词who, what, which;
疑问副词when, where, how, why
⑴ 连词that（无词意）, whether(是否), 在从句中不充当句子成分，只起连接作用; whether
能引导主语从句，而if不能。
That you don’t like him has nothing to do with me.
Whether John will do this experiment remains a question.
⑵ 连接代词who, what, which, 在从句中既作连接词又充当主语、宾语、表语、定语等。
Who will be sent abroad to further his studies is not announced.
What surprised me most was that such a little girl could play the violin so well.
Which school will win the prize is not known.
Whose dictionary has not been found is still unknown.
Whichever you take will be yours.
Whoever wants this book may take it.
Whatever was said here must be kept secret.
⑶ 疑问副词when, where, how, why在从句中充当时间状语、地点状语、方式状语、原
因状语
When they will start hasn’t been decided yet.
Where the heroine went is not mentioned at the end of the story.
How he managed to finish the composition in such a short time is still a mystery.
Why he often comes here is known to us all.
难点
1． 主语从句能用it作形式上的主语，而把真正的主语放在后面。常以it作形式主语的
句型有：
A. It+be+形容词(well-known, obvious, true, natural, surprising, good, wonderful, funny, possible, likely, certain, probable,
etc.)+that从句。如：
It is certain that she will do well in her exam. 毫无疑问她考试成绩会很好。
It is probable that he told her everything. 很可能他把一切都告诉她了。 B. It+be+名词词组(no wonder, an honour, a good thing, a pity, no surprise, common
Knowledge, a surprise, a fact, etc.)+that从句。如：
It’s a pity that we can’t go. 很遗憾我们不能去。
It’s no surprise that our team should have won the game. 我们没赢这场比赛真意外。
C. It+be+过去分词(said, reported, thought, expected, decided, announced, arranged,
etc.)+that从句。如：
It is said that Mr. Green has arrived in Beijing. 据说格林先生已经到了北京。
It is reported that China has sent another man-made earth satellite into orbit.
据报道中国又成功地发射了一颗人造地球卫星。
It has been suggested that much should be done to prevent the river from being
polluted. 有人建议应做更多的工作阻止河流受到污染。
D. It appears / seems that„„ （似乎„„）
It happens that„„ （碰巧„„）
It occurred to me that„„ （我突然想起„„）
It seems that Alice is not coming to the party at all. Alice似乎不来参加晚会。
It happened that I was out that day. 碰巧我那天外出了。
E. It+doesn’t matter (makes no difference, etc.)+连接代词或连接副词引起的主语从
句。如：
It doesn’t matter whether she will come or not. 她是否来这无关紧要。
It makes no difference where we shall have the meeting. 我们在哪里开会毫无区别。
F. 当that引导的主语从句出现在疑问句中时，要以it作形式主语，而把主语从句
后置。如：
Is it true that the scientist will give us a lecture next week?
下周那位科学家将给我们作报告是真的吗？
Does it matter much that they will not come tomorrow? 他们明天不来很要紧吗？
G. 当主语从句出现在感叹句中时，要以it作形式主语，而把主语从句后置。如：
How strange it is that the children are so quiet! 孩子们这么安静真奇怪！
2． 注意连接代词whoever, whatever, whichever等引导主语从句的含义
Whoever comes will be welcome. (whoever=the person who) 来的人将受到欢迎。
Whatever he did was right. (whatever=the thing that) 他所做的事情是正确的。
Whichever of you comes in will receive a prize. (whichever=anyone of you who)
你们当中不论哪个进来将会得到奖励。
表 语 从 句
基本概念
1． 定义：用作表语的从句叫做表语从句。
2． 构成：关联词+简单句
3． 引导表语从句的关联词的种类：
(1) 从属连词that。如：
The trouble is that I have lost his address. 麻烦是我把他的地址丢了。
(2) 从属连词whether, as, as if。如：
He looked just as he had looked ten years before. 他看起来还与十年前一样。
The question is whether they will be able to help us. 问题是他们是否能帮我们。
注：从属连词if一般不用来引导表语从句，但as if却可引导表语从句，如： All this was over twenty years ago, but it’s as if it was only yesterday.
这都是20多年前的事了，但宛如昨天一样。
能跟表语从句的谓语动词一般为系动词be, seem, look等。如：
It looked as if it was going to rain. 看起来天要下雨了。
(3) 连接代词who, whom, whose, what, which, whoever, whatever, whichever
连接副词 where, when, how, why。
如：The problem is who we can get to replace her. 问题是我们能找到谁去替换她呢。
The question is how he did it. 问题是他是如何做此事的。
That was what she did this morning on reaching the attic. 那就是她今晨上了阁楼干的。
难点
1． 连词because可引导表语从句。如：
I think it is because you are doing too much. 我想这是因为你做得太多。
2． 引导表语从句的that不省略，that仅起连接作用，在从句中不充当任何成分，无任何
意义
The impression he makes on me is that he is a reliable person.
他给我的印象是他是一个可靠的人。
3． the reason后面的表语从句只能用that引导，我们学生易犯“the reason is because„”
的错误
The reason why the little actress has been such a success is that she is both clever and
hard-working.
4． 在表示命令order等，建议suggestion, advice等的名词后的表语从句中，谓语动词要
用虚拟语气：should+动词原形，should可省略
His suggestion is that we (should) hold another meeting to discuss the problem.

1 高中英语语法讲义---- 名词性从句（主从、表从、宾从，同从）
1， 陈述句做名从用连词that + SV, that 表主句肯定从句完整，不做成分。主从可用it 做形式主语，宾从第一个that 可省略。 You study hard.
主从：That you study hard is known to us.= It is known to us that you study hard.
表从：My opinion is that you study hard .
宾从：I think (that) you study hard. …and that (不能省略)….
同从：My opinion that you study hard is known to us. *比较同从和主从！
一般抽象名词后对其进行解释和说明的完整句子就是其同位语从句，不完整就是定语从句。
I appreciate your idea that we have an exam every week. （that后完整—同从）
I appreciate your idea that you came up with last time.（that后不完整---定从）
2， 一般问句做名从用连词whether(是否) + SV，whether表主句不肯定从句完整，宾从中可用if（介词后或宾从后有or not时只用whether）。 Does your friend like English ?
主从：Whether your friend likes English isn’t clear .=It isn’t clear whether your friend likes English.
表从：My question is whether your friend likes English.

. 名词性从句讲义
一. 名词性从句
在句子中起名词性作用的从句叫做名词性从句(Noun Clauses). 名词性从句在句中的作用相当于名词或名词短语, 在复合句中担当主语, 宾语, 表语和同位语等. 因此根据它在句中不同的语法功能可分为: 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可分为三种:
连接词: that, whether, if (不在从句中做任何成分)
连接代词: what, who, whom, which, whose和wh+ever (通常在从句中做主语,宾语,表语等)
连接副词: when, where, why, how以及wh/h+ever(通常在从句中做状语)
二.主语从句
1.概念: 主语从句是在复合句中充当主语的从句.
2.连接词:
that只起连接主句和从句的作用,在从句中不担任任何成分,本身没有词义,不可省略
whether 连接主句和从句, 在从句中不担任任何成分, 但本身有选择或是否的含义
whether与if 区别
（一）引导宾语从句，一般既可用whether也可用if。但
1 or not放在whether之后时，只能用whether不用if。
I don’t know whether or not he will come.
我不知道他是不是回来。
注1：如果or not放在whether所引导的从句句尾，则可以用if来替换。
I don’t know whether/if he will come or
not.我不知道他是不是回来。
2 在强调任意选择时,用whether…or,此时不用if替换whether。 He asked me whether I wanted to go there by
train or by bus.他问我是想乘火车还是坐公共汽车去那里。
注：whether和or一起还有“不管”之意,引导让步状语从句。

名词性从句讲义 2
名词性从句
一， 名词性从句的概念：
1, 相当于名词，分为主语从句、表语从句、宾语从句和同位语从句
2，名词性从句的引导词：
that, whether, if (一般是宾语从句)，as if(表语从句)，who, whom, whose, what, which, when,
where, why, how,以及由how组成的词组， 如：how many, how long, how far
两组需要注意的连接词
that/what
1）that和what都可以引导名词性从句，但that是连接词，本身无词义，仅起连接作用，不在从句中担任任何成份；what是连接代词，不仅引导名词性从句，而且在从句中充当一定的成份，如主语、宾语或表语。
e.g: That he stole a bike was true.
The important thing is what you do, but not what you say.
高考真题：
_______ we can't get seems better than _______ we have.
A. What; what B. What; that C. That; that D. That; what
2）whether和if均可引导动词后的宾语从句，常可互换。
a.在介词后面只能用whether，不能用if。
例如： ①This depends upon whether we are determined to do it.
b. 在动词不定式之前，只能用whether，不能用if。
例如： ①He doesn't know whether to stay or not.
c.引导主语从句，表语从句，同位语从句时只能用whether。
例如： ①It is unknown whether he will come. 他是否来还不知道。
高中名词性从句讲义
名词性从句
名词性从句相当于名词，可分别作主句的主语、表语、宾语和同位语。因此，名词性从句可分为主语从句、表语从句、宾语从句和同位从句。
（一）引导名词性从句的连接词
1、连接代词：who, whose, 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（好象）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）。
(二)主语从句、宾语从句、表语从句
1）构成：关联词+简单句
2）例如：
Who is on duty hasn’t been decided.
We haven’t decided who is on duty.
The question is who is on duty.
What he is doing is a question.
I don’t know what he is doing.
The question is what he is doing.
How he gets so much money is still a question.
I don’t know how he gets so much money.
The question is how he gets so much money.
