名词性从句讲解
在复合句中起名词作用的从句叫做名词性从句。它包括主语从句、宾语从句、表语从句和同位语从句。
一、名词性从句
主语从句、表语从句、宾语从句、同位语从句，在整个句子中所起的作用，相 当于一个名词。因此，这
四种从句通称为名词性从句。
引导名词性从句的连接词可分为三类：
连接词：that, whether, if （不充当从句的任何成分）
连接代词：what, whatever, who, whoever, whom, whose, which.
连接副词：when, where, how, why
1. 主语从句 （两种结构，三类连接词）
两种结构
1.主语从句位于句首：
What he wants is a book.
Who kept the door open all night was unknown.
2.主语从句位于句尾，it 作形式主语。
（1）It + be + 名词 + that从句
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。
（2）It + be + 形容词 + that从句.
It seems obvious that we can not go on like this. 很明显我们不能这样下去了
（3）It + be + 动词的过去分词 + that从句
It is known to all that light travels in straight lines.众所周知光沿直线传播。
It is reported that China has sent another man-made earth satellite into orbit.
（ 4）It + 不及物动词 + that 从句
注意在主语从句中用来表示惊奇、不相信、惋惜、理应如此等语气时，谓语动词要用虚拟语气“(should)
+do”，常用的句型有：
It is necessary (important, natural, strange, etc.) that …
It is a pity (a shame, no wonder, etc.) that…
It is suggested (requested, proposed, desired, etc.) that…
三类连接词:
1.连词that whether
that引导的主语从句:引导词that无含义,在句中不做成分,不可以省。
whether 引导的主语从句:whether有含义(是否),在句中不做成分,不可以省。
That you will win the medal seems unlikely. 你想获得奖牌看起来是不可能的。
That she survived the accident is a miracle. 她在事故中幸免于难简直是奇迹。
Whether she is coming or not doesn’t matter too much. 她来不来都无关紧要。
2.连接代词who, whose, whom, which, what, whoever, whomever, whichever, whatever引导的名词性从句
中，其连接代词在句中起名词性作用，担当一定成分.
What you need is more practice.你所需要的是更多的训练。
What I want to know is this. 我想知道的就是这事。
Whatever we do is to serve the people.我们无论做什么都是为人民服务。
3.连接副词when, where, why, how引导的名词性从句(其连接副词有含义,在句中作状语。)

2. 宾语从句
名词句用作宾语的从句叫宾 语从句。引导宾语从句的关联词与引导主语从句表语从句的关联词大致
一样，在句中可以作谓语动词或介 词及非谓语动词的宾语。
1. 由连接词that引导的宾语从句
由连接词that引导宾 语从句时，that在句中不担任任何成分，在口语或非正式的文体中常被省去，
但如从句是并列句时, 第二个分句前的that不可省。例如：
He has told me that he will go to Shanghai tomorrow. 他已经告诉我他明天要去上海。
We must never think (that) we are good in everything while others are good in nothing.
我们决不能认为自己什么都好，别人什么都不好。
注意：在demand、order、suggest、decide、insist, desire, demand, request, command等表示要求、命令、
建议、决定等意义的动词后，宾语从句常用“（should）+ 动词原形”。例如：
I insist that she (should) do her work alone. 我坚持要她自己工作。
The commander ordered that troops (should) set off at once. 司令员命令部队马上出发。
2. 用who，whom, which, whose, what, when, where, why, how, whoever, whatever, whichever等关联词
引导的宾语从句相当于特殊疑问句，应注意句子语序要用陈述语序。
例如： I want to know what he has told you. 我想知道他告诉了你什么。
She always thinks of how she can work well. 她总是在想怎样能把工作做好。
She will give whoever needs help a warm support. 凡需要帮助的人，她都会给予热情的支持。
3. 用whether或if引导的宾语从句，其主语和 谓语的顺序也不能颠倒，仍保持陈述句语序。此外，whether
与if 在作“是否”的意思讲时在下列情况下一般只能用whether，不用if：
a. 引导主语从句并在句首时；b. 引导表语从句时；c . 引导从句作介词宾语时；d. 从句后有“or not”时；
e. 后接动词不定式时。
Whether there is life on the moon is an interesting question. 月球上有没有生命是个有趣的问题。
Everything depends on whether we have enough money. 一切要看我们是否有足够的钱。

4. 注意宾语从句中的时态呼应，当主句动词是现在时，从句根据自身的句子情况，而使用
不同时态。
例如： he studies English every day. （从句用一般现在时）
he studied English last term. （从句用一般过去时）
I know (that) he will study English next year. （从句用一般将来时）
he has studied English since 1998. （从句用现在完成时）
当主句动词是过去时态（could, would除外），从句则要用相应的 过去时态，如一般过去时，过去进
行时，过去将来时等；当从句表示的是客观真理，科学原理，自然现象 ，则从句仍用现在时态。
例如：The teacher told us that Tom had left us for America．
5. think, believe, imagine, suppose等等动词引起的否定性宾语从句中，要把上述主句中的动词变为否定
式。即将从句中的否定形式移到主句中。
The news that we won the game is exciting.（that引导同位语从句，不能省略）
The news that he told me is exciting.（that引导定语从句，作宾语，可以省略）

3. 表语从句
引导的表语从句
that仅起连接作用，无意义，在句 中不作任何成分，通常不能省略。这种从句往往对主句主语的内
容起进一步解释的作用。其基本结构为： 主语+系动词+that从句。如：

名词性从句讲解及专项练习习题及解答
The fact is that we have lost the game.

当主语是reason时，表语从句要用that引导而不是because。如：
The reason why he was late was that he missed the train by one minute this morning.
-疑问词引导的表语从句
①连接代词what，which，who，whom，whose除在句子中起连接作用外，还可在从 句中充当主语、
宾语、表语、定语，且各有各的词义。如：
o在从句中作主语
在从句中作系动词be的表语
②连接副词when,where,how,why除在句中起 连接作用外，在从句子中还充当时间，地点，方式，原
因状语，本身具有词义。如：

③whether引导的表语从句
连接词whether起连接作用，意为“是否，究竟 ，到底”(注意：if不能引导表语从句)，在句中也不作
任何成分。
The q
3.其他连词as if,because,as,as though引导的表语从句
because引导表语从句通常只用于“ThisThatIt iswas because...”结构中。as ifas though引导的表语从
句常置于系动词look ，seem，sound，be，become等后面，常用虚拟语气，表示不存在的动作或状态。
如：
The elephant feels as iftho大象摸起来像一堵墙。
It looks as if it is going to rain.
4.主语是表示建议、命 令、要求等的名词，那么表语从句应该用虚拟语气，即should后接动词原
形,(should可以 省略)。如：

练习
problem is ________will go to the meeting.
A. why B. when C. what D. who
looks _______ it were going to rain.
A. even if B. as if C. even though D. like
is _______ he likes the place so much.

6. The energy is ________ makes the cells able to do their work.

4. 同位语从句
同位语从句说明其前面 的名词的具体内容。同位语从句通常由that引导，可用于同位语从句的名词
有advice、dem and、doubt、fact、hope、idea、information、message、news、 order、problem、promise、
question、request、suggest ion、truth、wish、word等。例如：
The news that we won the game is exciting. 我们赢得这场比赛的消息令人激动。

The thought came to him that Mary had probably fallen ill. 他想到可能玛丽生病了。
同位语从句和定语从句的区别：
that作为关系代词，可以引导定语从句，充当句子成分，在从句中作宾语时可以省略； that引导同
位语从句时，起连词的作用，没有实际意义，不充当句子成分，一般不能省略。
试比较下面两个例句:
I had no idea that you were here．（that引导同位语从句，不能省略）
Have you got the idea（that）this book gives you of life in ancient Greece？（that引导定语从句，作宾语，
可以省略）
