名词性从句解及专项练习习题及其解答

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。名词性从句是中学阶段的一个重要语法项目，在历年的高考中几乎都涉及到，并且每年的命题各有变化。分析历届高考试题名词性从句考查的焦点主要有以下六个方面

1. 考查名词性从句的语序问题

2. 考查引导词that与what的区别

3. 考查it在名词性从句中作形式主语或形式宾语的用法

4. 考查whether与if的区别

5. 考查名词性从句中的疑问词+ever引导的名词性从句与no matter+疑问词引导的状语从句的区别

6. 考查名词性从句的虚拟语气问题

语法要点剖析

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

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，when，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 …

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。

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。

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。

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

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、demand、doubt、fact、hope、idea、information、message、news、order、problem、promise、question、request、suggestion、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。

I have no idea when he will come back home. 我不知道他什么时候回来。

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）

高中英语名词性从句专项练习

高中英语名词性从句专项练习 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 主语从句 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 … It is a pity (a shame, no wonder, etc.) that… It is suggested (requested, proposed, desired, etc.) that… 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： 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。 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、demand、doubt、fact、hope、idea、information、message、news、order、problem、promise、question、request、suggestion、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。 I have no idea when he will come back home. 我不知道他什么时候回来。 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） 名词性从句专项练习100题 1. His success was because of ________ he had been working hard. A. that B. the fact which C. the fact that D. the fact 2. “Is Mary from New York City” “I don't know _______.” A. from what city does she come from B. from what city she come C. what city does she come from D. what city she comes from 3. ________ makes mistakes must correct them. A. What B. That C. Whoever D. Whatever

复习专题名词性从句专项练习题及答案 一、初中英语名词性从句 1． is known to all is that the earth is smaller than the sun. A. As B. What C. It D. Which 【答案】 B 【解析】【分析】句意：众所周知地球比太阳小。 is known to all 是主语从句，从句中缺少主语，因此用what，选B。 【点评】考查名词性从句，本题涉及what引导的主语从句。 2．Has it been announced ______? A. when are the planes to take off B. that are the planes to take off C. where are the planes to take off D. when the planes are to take off 【答案】 D 【解析】【分析】句意: 飞机什么时候起飞已经宣布了吗？此处是when引导的主语从句，且要用陈述句语序，故选D。 【点评】考查名词性从句，it作形式主语，关系副词when引导的从句作真正的主语。 3．In the past decade, our education system too much on grades. However, grades have a direct connection with future success is still a question. A. focused; whether B. focused; if C. has focused; whether D. has focused; if 【答案】 C 【解析】【分析】考查时态和主语从句。根据In the past decade,在最近的几十年里，可知句子用现在完成时态，our education system是句子的主语，单数形式，所以第一空填has focused；第二空是主语从句做主语，if是否，不能引导主语从句，所以第二空填whether。故选C。 【点评】主语从句主要有三类： 1）（1）由连词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。例如：That you will win the medal seems unlikely.你想获得奖牌看起来是不可能的。（2）用连词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。例如：Whether she is coming or not doesn't matter too much.她来不来都无关紧要。注意：if不能引导主语从句。 2）用连接代词引导的主语从句（在由连接代词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）.例如：What you need is more practice.你所需要的是更多的训练。 3）用连接副词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。）例如：Where we should leave it is a problem.
