英语名词性从句练习全集

一、初中英语名词性从句

1．We believe ________ you have been devoted to ________ naturally of great necessity.

A. that; being

B. all that; be

C. that all; are

D. what; is

【答案】 D

【解析】【分析】句意：我们相信你所投入的当然是非常必要的。分析句子可知，believe 后接宾语从句，宾语从句中you have been devoted to缺少宾语，表示事物故用what；what you have been devoted to为主语，从句作主语，谓语动词用单数，故选D。

【点评】考查名词性从句和主谓一致，本题涉及what引导的主语从句和一般现在时。

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．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。

4．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。

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．________ we may find interesting is that it usually takes more to be polite.

A. That

B. What

C. Which

D. /

【答案】 B

【解析】【分析】句意：我们可能会发现有趣的是通常需要更多的礼貌。此处是主语从句做主语，从句没有引导词，缺少宾语，故答案为B。

【点评】考查名词性从句，本题涉及what引导的主语从句的应用。

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

A. that

B. it

C. what

D. which

【答案】 C

【解析】【分析】句意：他们在森林里迷路了，更糟糕的是天开始黑了。根据连词and可知，本句需要一个引导主语从句的连接词，该词同时还要能在从句里充当主语。that不能在句中作成分；it不能引导主语从句；which意为“哪一个”，不符合本句语境。排除A、B、D三项。故选C。

【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．____________ matters most in learning English is enough practice.

A. Why

B. That

C. Which

D. What

【答案】 D

【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。

9．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
