外研版英语名词性从句单元测试题(含答案)经典含答案解析
一、初中英语名词性从句
1.It is a rule in his family that _______ comes home first should cook the dinner.
A. anybody
B. who
C. whoever
D. who that
【答案】 C
【解析】【分析】句意:在他的家里有个规定,就是先到家的人要先做饭。

whoever 有两个词义:1no matter who,在这种用法时引导一个让步状语从句;2anybody that,在这种用法时,它连接一个名词性从句,在本题中它连接的是主语从句。

这里就是第二个用法。

所以选C。

2.________ is known to us all that the old scientist, for ________ life was hard in the past, still works hard in his eighties.
A. As; whose
B. It; whose
C. As; whom
D. It; whom
【答案】 D
【解析】【分析】句意:我们都知道,那位老科学家,过去生活很艰苦,到了八十多岁还在努力工作。

第一空it is known to us all that…是个固定句型,意为“众所周知…”;第二空为介词+关系代词引导的定语从句,先行词the old scientist指人,作介词for的宾语,只能用whom,故选D。

【点评】考查名词性从句和定语从句,本题涉及固定句式it is known to us all that…和whom引导的限制性定语从句。

3._______ caused the accident has not been found out yet.
A. What
B. Which
C. The thing
D. That
【答案】 A
【解析】【分析】句意:造成事故的原因还没有查明。

此处为主语从句,从句中缺少主语,应该用what引导,故答案为A。

【点评】考查主语从句。

以及what的含义。

4._______is known to us all is that Johnson broke his promise ______ he would come to help me as soon as possible.
A. It; that
B. What; that
C. As; which
D. What; which
【答案】 B
【解析】【分析】句意:我们都知道,Johnson违背了他会尽快来帮助我的诺言。

分析句子结构可知,第一空为主语从句,从句中缺少主语,所以用what,第二空为同位语从句,从句结构完整,所以用that解释promise的内容,故选B。

【点评】考查名词性从句,本题涉及主语从句和同位语从句。

5.________ 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。

6.It matters little ______ a man dies, but _____ matters much is ______ he lives.
A. how; what; how
B. how; it; how
C. why; it; why
D. that; what; that 【答案】 A
【解析】【分析】句意:一个人如何死去并不重要,重要的是他如何生活。

it为形式主语,how从句为真正的主语。

What matters much (=the thing that matters much)。

第一个how引导的是一个主语从句;it作形式主语;what引导的是主语从句;第二个how引导的是表语从句。

故选A。

【点评】考查名词性从句,本题涉及主语从句和表语从句的应用。

7.They lost their way in the forest, and ________ made matters worse was that night began to fall.
A. it
B. which

故选D。

【点评】考查名词性从句,本题涉及what引导的主语从句的应用。

8.________ has been proved is that animals and insects have their own languages.
A. What
B. As
C. It
D. That
【答案】 A

9.He took a trip to Beijing last week and ________ he saw at the Forbidden City impressed him
deeply.
A. that
B. how
C. what
D. which
【答案】 C
【解析】【分析】句意:上周他到北京旅行了,他在故宫所看到的给他留下了深刻的印象。

分析句子结构可知,连词and后为一个名词性从句,因此应该使用what引导,且what在从句中作主语,故选C。

【点评】考查名词性从句,本题涉及what引导的主语从句。

10._______ 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。

11.—What impresses you most when you visit the Acropolis ?
— ________ it is that has brought the grand palace into today's terrible scene.
A. Where
B. What
C. How
D. When
【答案】 B
【解析】【分析】句意:——当你参观雅典卫城时,你印象最深的是什么?——使我印象最深的是什么将从前宏伟的宫殿变成了今天惨不忍睹的样子。

强调句型的特殊疑问句式:疑问词(如what) is it that+其它,本句强调的是什么使得从前宏伟的宫殿蜕变的,所以用表示内容的what,选B
【点评】考查主语从句和强调句,本题强调主语从句的引导词。

12.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。

13.—Tell me something about your adventure in the rainforest, please.

A. what; that
B. it; that
C. it; because

B. That ; that
C. What; whether
D. It; that
【答案】 A
【解析】【分析】句意:让我更不高兴的是那个男孩要求我的朋友做他的女友,她同意了。

第一空填what,它一方面在句子中引导主语从句,另一方面又在主语从句中作主语;第二空用that引导表语从句且从句中不缺成分,表示对前面情况的说明。

故选A。

【点评】考查了名词性从句,本题涉及what引导的主语从句以及that引导的表语从句。

15.Located between the 16th and the 18th fl oor, ______ I call my “home” is more like a “bird's nest”.
A. which
B. that
C. what

故选C。

16.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。

17._______ are playing an important part is well known to us all.
A. That who
B. Those who
C. Who that
D. Who
【答案】 D
【解析】【分析】考查主语从句。

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。

19.Some people believe _______ has happened before or is happening now will repeat itself in the future.
A. whatever
B. whenever
C. wherever
D. no matter what
【答案】 A
【解析】【分析】句意:一些人认为之前发生的或现在正在发生的任何事情在将来都会重复发生。

Whatever has happened before or is happening now是一个主语从句,whatever既引导起这个主语从句,也在句中做主语。

BC项都属于副词的性质,都不能做主语,通常只能做状语;no matter what只能用来引导状语从句,故选A。

【点评】考查名词性从句,本题涉及"特殊疑问词+ever"引导的主语从句。

A. That, what
B. What, that
C. That, that
D. What, what
【答案】 B
【解析】【分析】句意:使NBA世界惊讶的是Kobe Bryant在一场比赛中得了81分。

根据句意可知,句子主语是一个主语从句,引导词即起引导作用又要做从句的一个成分,所以第一空填What;第二空是that引导的表语从句,只起引导作用,故选B。

【点评】考查名词性从句,本题涉及关系代词what引导的主语从句和表语从句的应用。

21.It that everyone to laugh.
A. seems,loves

A. when the school sports meeting ended
B. when did the school sports meeting end
C. when the school sports meeting ends
D. when does the school sports meeting end
【答案】 A
【解析】【分析】句意:你能告诉我昨天下午学校学校运动会什么时候结束的吗?could you tell me后接宾语从句,用陈述语序,疑问词+主语+谓语,因此排除B、D;根据yesterday afternoon,昨天下午可知,此句是过去时态,故选A。
