二、用适当的连词填空：
1. That 2. Whether, whether 3. Whether 4. whether 5. whether 6. It 7. Whoever
r 9. that 10. why 11. how er

1. 【误】 He has come back so early surprises all of us.
【正】 That he has come back so early surprises all of us.
【析】 that引导名词性从句时, 尽管无意义也不充当成分,但除了在动词后引导单个宾语从句时可省略外，其它
情况下不能省略。
2. 【误】 That he really means is what he doesn’t agree with us.
【正】 What he really means is that he doesn’t agree with us.
【析】 that和what均可引导名词性从句，区别在于：what在名词性从句中作主语、宾语或表语，而that 在名
词性从句中不作任何成分，只起连接作用。误句的主语从句应该用what作means的宾语，表 语从句中应该用that，
因为that在从句中不作任何成分。
3. 【误】 The news which our team had won pleased everyone.
【正】 The news that our team had won pleased everyone.
【析】 which在此句中不充当成分，说明从句不是定语从句而是同位语 从句。同位语从句不能用which引导，
故改为that。
4. 【误】 The reason why he failed in the exam was because he was too careless.
【正】 The reason why he failed in the exam was that he was too careless.
【析】主语为reason时，引导表语从句的关联词一般用that，不用because，构成The reason why for which that
for ... is that ... 句型。because引导名词性从句只用于It This That is because ... 结构。
5. 【误】 It is unknown that where we will have the meeting.
【正】 It is unknown where we will have the meeting.

【正】 The problem is when he will come back.
【析】 名词性从句应该用陈述句语序，即“引导词 + 主语 + 谓语”。
7. 【误】 Could you tell me which was the way to the Science Museum?
【正】 Could you tell me which is the way to the Science Museum?
【析】当主句为过去时态的时候，宾语 从句中要用过去的某种时态。但该句中的could不是表示过去，而是表
示一种委婉的语气，故宾语从 句中的谓语动词应用一般时态。
8. 【误】 If he is an engineer is unknown.
【正】 Whether he is an engineer is unknown.
【析】 if不能用来引导主语从句，在表示“是否”这一意义时要用whether。
9. 【误】 I have been worrying about if I have hurt her feelings.
【正】 I have been worrying about whether I have hurt her feelings.
【析】 if和whe ther引导动词后的宾语从句时可互换。但介词后的宾语从句及主语从句、表语从句、同位语从
句只能 用whether引导。

2

10. 【误】 What he needs are enough time and what I need is enough books.
【正】 What he needs is enough time and what I need are enough books.
【析】名词 性从句作主语时，若表语为单数名词或不可数名词，则谓语动词用单数；若表语为可数名词复数，
则谓语 动词常用复数。若谓语为动词则用单数。
11. 【误】 No matter who comes to visit the exhibition is welcome.
【正】 Whoever comes to visit the exhibition is welcome.
【析】 “No matter + 疑问词”结构只能引导让步状语从句，“wh- + ever”既可引导让步状语从句，也可引导名词
性从句。
12. 【误】 I’ll make known to all that you were not honest.
【正】 I’ll make it known to all that you were not honest.
【析】当复合宾语的第一个成分是宾语从句时，须用it作形式宾语，而将真正的 宾语从句后置。其句式为：主
语 + 动词 + 形式宾语it + 宾补（形容词或名词）+ 宾语从句。又如：I found it quite pleasant that I worked with him.
13. 【误】 He is said that he has gone to America.
【正】 It is said that he has gone to America.
【析】 It is said that是一固定句型，it为形式主语，不可用其他词代替。
14. 【误】 My suggestion is that we will learn more words by heart.
【正】 My suggestion is that we should learn more words by heart.
【析】 主语为suggestion, advice, order, proposal等名词时，表语从句要用虚拟语气，即用“（should） + 动词
原形”的结构。这些名词的同位语从句也要用虚拟语气。
15. 【误】 Why we decided to put off the meeting is because we had some difficulty in preparing it.
【正】 Why we decided to put off the meeting is that we had some difficulty in preparing it.
【析】 why引导主语从句时，表语从句要用that引导。

概念
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等
1. 主语从句
作句子主语的从句叫主语从句。主语从句通常由从属连词that，whether，if和 连接代词what，who，which，
whatever，whoever以及连接副词how，w hen，where，why等词引导。that在句中无词义，只起连接作用；连
接代词和连接副词在 句中既保留自己的疑问含义、又起连接作用，在从句中充当从句的成分。例如：
What he wants to tell us is not clear. 他要跟我们说什么，还不清楚。
It is known to us how he became a writer. 我们都知道他是如何成为一名作家的。
Where the English evening will be held has not yet been announced.
英语晚会将在哪里举行，还没有宣布。
有时为避免句子头重脚轻，常用形式主语it代替主语 从句作形式主语放于句首，而把主语从句置于句末。
主语从句后的谓语动词一般用单数形式。常用句型如 下：
（1）It + be + 名词 + that从句 （2）It + be + 形容词 + that从句
（3）It + be + 动词的过去分词 + that从句 （4）It + 不及物动词 + that 从句
另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 …

3

It is a pity (a shame, no wonder, etc.) that…
It is suggested (requested, proposed, desired, etc.) that…
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。
例如： 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。
☆可用if的情况
1. Vt.动词后面跟的宾语从句 I don’t know whetherif he will come.
2. 不作句首的主语从句（it作形式主语的从句）It’s doubtful whetherif he is coming.
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：I know he studies English every day. （从句用一般现在时）
I know 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）
I know 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, supp ose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。
例如： We don’t think you are here. 我们认为你不在这。
I don’t believe he will do so. 我相信他不会这样做。
3. 表语从句
在句中作表语的从句叫表语从句。引导表语从句的关 联词与引导主语从句的关联词大致一样，表语从句位
于连系动词后，有时用as if引导。其基本结构为：主语 + 系动词 + that从句。例如：
The fact is that we have lost the game. 事实是我们已经输了这场比赛。
That is why he didn’t come to the meeting. 那就是他为什么不到会的原因。

4

It looks as if it is going to rain. 看上去天要下雨了。
需要注意的，当主语是reason时，表语从句要用that引导而不是because。例如：
The reason why he was late was that he missed the train by one minute this morning
4. 同位语从句
在句中作同位语的从句叫同位语从句。它一般跟在某些名词（如fact，idea，news， promise,thought等）的
后面，用以说明或解释前面的名词，引导同位语从句的词有连词 that，连接副词how，when，where等。例如：
I have no idea when Chaplin’s film will be on again.
We were very excited at the news that our team had won.
The fact that women can work as well as men is clear.
Henry made a promise that he would not open the letter until 2 o’clock.
