名词性从句考点突破

在复合句中起名词作用的从句叫作名词性从句。它包括主语从句、宾语从句、同位语从句和表语从句。

名词性从句是英语中的一个重要语法项目，在历年的高考中几乎都涉及到。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 辨别从句类型 (将从句视为一个整体，看从句在复合句中作什么成分就叫什么从句)

从句的结构：从属连词 + （主语）+ 谓语

What you did is right. ___________从句

It is what you want. ___________从句

You can do whatever you like. _____________从句

The news that he won the first prize is amazing. ____________从句

② 填写引导词

从句不缺成分，只陈述 that

从句表示质疑，不确定 whether

if（宾语从句）

从句缺成分与特殊疑问句的提问词一样

如从句缺 sb.，填 who; （whom 作宾语）

从句缺 sth.，填 what

(注意：whoever, whatever, whichever 等有让步之意，“不管…”)

1. I know ______ the earth moves around the sun.

2. I know _________ did it.

3. It is still unknown______ Jane is willing to join in this activity.

4.Tell me _____ you go to school. By bus or on foot?

5. It is certain ____ he will win the match.= _____ he will win the match is certain.

6. ______ book was lost is unknown.

7.The fact _____Chinese culture enjoys a long history can’t be denied.

③ 用名词性从句完成下列句子。

1. ______________________________(她是否要来) doesn’t matter.

2. Nobody knew ________________________(他为什么突然如此生气).

3. He put forward the suggestion ___________________________(重要问题应该先讨论).

4. Lily doesn’t know _____________________(昨晚发生了什么事).

5. ____________________________________(凡犯了错误的人) must correct them.

考点 It is...和There is...

It is...句型中 it 为形式主语，真正的主语为动名词、不定式或从句，而 There is 意为“有……”，有时

be 也可以用 exist，remain 等替代。

用it，there 填空：

________ is a pity that he was absent.①

________ is a fact that he has lied to you.②

________ is no wonder that he is so excited.③

________ is no need to worry about it.④

________ is no sense/point (in) arguing with him.⑤

________ is no doubt that he has gone.⑥

【答案】① It　② It　③ It　④ There　⑤ There　⑥ There

考点从句作主语时的谓语动词形式

主语从句作主语相当于第三人称单数作主语，谓语动词用单数；如果由 and 连接两个或两个以上的主

语从句作主语时，谓语动词用复数；由两个或多个连接词引导一个主语从句，谓语动词用单数。

用所给词的适当形式填空：

That the president is coming ________(excite) all of us.①

How close parents are to their children ________(have) a strong influence on their character.②

When and where the meeting will be held ____________(not decide) yet.③

【答案】① excites　② has　③ isn't decided/hasn't been decided

考点　　宾语从句的时态和语序

宾语从句中的时态要注意呼应。当主句中的谓语是现在时，从句根据自身的句子情况，而使用不同的

时态。当主句中的谓语是过去时态，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、科学真理、自然现象，则从句仍用现在时态。宾语从句语序

要用陈述语序(what is/was the matter 除外)。

The photographs will show you ________① ．

A. what does our village look like

B. what our village looks like

C. how does our village look like

D. how our village looks like

Someone is ringing the doorbell. Go and see ________② ．

A. who is he B. who he is C. who is it D. who it is

Hello③ ，I didn't know you ________(be) in London. How long have you been here?

I thought he ________(be) coming tomorrow.④

The teacher told us that light ________(travel) at a very high speed.⑤

【答案】① B　② D　③ were　④ was　⑤ travels

考点　　表语从句中的常见句型

常用的句型有：The reason is that...；It is because...；That's why...；That's where...。

完成下列句子：

The reason ________ he is absent from school is ________ he is ill.①

＝He is ill. That's ________ he is absent from school.

＝He is absent from school. That's ________ he is ill.

The reason ________ he gave was ________ he was caught in the traffic jam.②

That's ________ I disagree/the problem lies/I have doubt/you are mistaken.③

That's ________ I disagree about/the problem lies in/I have doubt about/you are mistaken about.

【答案】① why；that；why；because　② which；that/不填 ③ where；what

考点　　同位语从句和定语从句的辨别

同位语从句就是在复合句中作名词的同位语的名词性从句。连接词 that 引导同位语从句时，应在某些

抽象名词之后，如：

fact，hope，story，thought，suggestion，idea，news，possibility，feeling，doubt，truth，wish，word

(消息)，request，information，order，message 等，对前面的名词起补充说明的作用。同位语从句有时

可以不紧跟在它所说明的名词后面，而是被别的词隔开。定语从句中的 that 是关系代词，既起引导从

句的作用，同时又在从句中充当主语或宾语，而同位语从句中的 that 是连词，只起连接主句与从句的

作用，不充当句中任何成分。

完成下列句子：

The news ________ he told us excited us.①

The news ________ our team won the game excited us.

The fact ________ he collected was surprising.②

The fact ________ he said nothing was surprising.
