名词性从句考点解析(Word版附答案)1
一、名词性从句
1.It was never clear ________ the man hadn't reported the accident sooner.
A. that
B. how
C. when
D. why
【答案】 D
【解析】【分析】句意:这名男子没有早点报告这次事故的原因根本没有搞清楚。

It在句中是形式主语,真正的主语是why引导的主语从句。

故选D。

【点评】考查名词性从句,本题涉及why引导的主语从句。

2.It has been pointed out ________ plays a vital role in driving away one's anxiety is one's sweet childhood memories.
A. what that
B. which
C. that
D. that what
【答案】 D
【解析】【分析】句意:有人指出,驱除焦虑所起着至关重要的作用是童年美好的回忆。

本句时一个主语从句,it作形式主语,真正的主语为that what plays a vital role in driving away one's anxiety is one's sweet childhood memories.,主语从句中又有一个主语从句,且此主语从句中缺少主语,所以用what引导。

故选D。

【点评】考查名词性从句,本题涉及what引导的主语从句。

3. is even more important is the earth cooled down, water began to appear on its surface.
A. When; that; when
B. What; whether; as
C. What; that; as
D. lt; whether; as 【答案】 C
【解析】【分析】这题考查从句的用法,第一空填what引导主语从句,在主语从句中what做主语,第二空填that引导表语从句,在表语从句中,as是引导时间状语从句,句意是:甚至更重要的是:随着地球的冷却,水开始出现在表面。

选C。

4.It________that the road will be closed tomorrow for repairs.
A. was announced
B. has been announced
C. had been announced
D. would be announced
【答案】 B
【解析】【分析】本题考查动词的时态和语态。

题干句子中that到句子结束是宾语从句,且从句动词用“will+动词原形”表示将来,由此推断出空白处谓语动词应用现在的某种时态,在所给四个选项中,只有B项正确。

【点评】考查现在完成时的被动语态,其结构是have/has +been +done。

需要注意宾语从句的时态。

主句用现在时,从句所需的任何时态。

5.—Tell me something about your adventure in the rainforest, please.
— We lost our way in the forest and ___ made matters worse was ___ night began to fall.
A. what; that
B. it; that
C. it; because
D. what; because
【答案】 A
【解析】【分析】考查名词性从句的连接词。

第一空what作主语从句的主语;第二空为表语从句的that。

6.They lost their way in the forest, and ___ made matters worse was that night began to fall.
A. it
B. which
C. that
D. what
【答案】 D
【解析】【分析】本题中含有一个主语从句what made matters worse,其中的what引导起这个主语从句,同时在主语从句中做主语。

AC两项不能引导主语从句,which在引导名词性从句的时候总是含有疑问的语义,而本句中并没有疑问的语义。

句意:他们在森林里迷路了,情况更糟糕的是天又黑了。

故D正确。

7._______ you don't like him is none of my business.
A. What
B. Who
C. That
D. Whether
【答案】 C
【解析】【分析】句意:你不喜欢他,跟我没有什么关系。

you don't like him为主语从句,其内容已经是完整的,所以用that,且引导主语从句的that不能省略。

8.________ the weather will not clear up until next week is bad news for us.
A. As
B. If
C. Whether
D. That
【答案】 D
【解析】【分析】考查主语从句。

句意:直到下周天气才放晴,这对我们来说是坏消息。

此处是that引导的主语从句,that无实义,只其引导作用,故答案为D。

【点评】主语从句属于名词性从句,在名词性从句中,that无实义,只起连接作用,不做句子成分;if/whether起连接作用,不做句子成分,有实义“是否”。

做题时注意看从句是否少成分。

9.____________ matters most in learning English is enough practice.
A. Why
B. That
C. Which
D. What
【解析】【分析】句意:学习英语中最重要的是有足够的练习。

A. why为什么;B. that引导名词性从句只起引导词作用,不充当成分;C. which哪一个;D. What什么。

根据语境用what引导主语从句,并在句中做主语。

故答案选D。

【点评】考查主语从句的引导词。

主语从句属于名词性从句的一种,填哪个连接词要分析从句缺少什么成分,然后确定所选的词。

10.________ manners are very important in every country is known to all,but the trouble is that different countries have different ideas about ________ good manners are.
A. That; what
B. That; that
C. What; that
D. What; what
【答案】 A
【解析】【分析】句意:众说周知,礼貌在每一个国家中都是非常重要的,但是麻烦是,不同的国家对于什么是良好的礼貌有着不同的认识。

逗号前有两个谓语动词,一个是are,一个是is known,故是两句话,需填连词连接这两句话,根据句意可知,前面是主语从句,故填that,此处的that,只起连接作用不作任何成分。

about是介词,其后是个句子故应填连词把这两句话连接起来,所缺词作are的表语,故填what。

因此选A。

【点评】考查名词性从句,本题涉及that引导的主语从句和what引导的宾语从句。

A. What
B. Which

A. It's the sun and not the earth
B. The sun and not the earth
C. Being the sun and not the earth
D. That the sun and not the earth
【答案】 D
【解析】【分析】句意:太阳而不是地球是我们行星系统的中心,这在中世纪是一个很难理解的概念。

分析句子可知,整个句子为主系表结构,was为系动词,它之前的都为主语,且主语由句子来充当,句子结构以及句意完整,所以连词代词为that。

故选D。

【点评】考查名词性从句,本题涉及that引导的主语从句。

A. that
B. how
C. what

故选B。
