（英语）英语名词性从句练习题含答案

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． 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。

3．--- made her ashamed of herself?

--- the lowest mark in her class.

A. What; Because she got

B. Was it what; Getting

C. What was it that; That she got

D. What was it that; Get

【答案】 C

【解析】【分析】句意：——是什么让她对她自己感到羞愧？——是她获得了她班上的最低分让她惭愧。A中的what是句子的主语，但是because引导的从句不作主语，是原因状语从句，故排除；B的第一空是错误形式，故排除；C、D两项的第一个选项是一样的，说明第一个题干是一个强调句型，特殊疑问句下的强调句型，有what引导；第二个空是对what的回答，因为what是上一句的主语，That she got the lowest mark in her class是从句，可以作主语；而D项的get是动词原形，不能作主语，故答案为C。

【点评】考查强调句型的使用和对特殊疑问句的回答，注意问什么回答什么，也就是说疑问词what是句子的主语，回答的内容也需要在句子中能作主语。

4．Located between the 16th and the 18th floor, ______ I call my “home” is more like a “bird's nest”.

A. which

B. that

C. what

D. where

【答案】 C

【解析】【分析】考查主语从句。What引导主语从句______ I call my “home”且 What在从

句中充当call的宾语。故选C。

5．____ made me more unhappy was ___ the boy asked my friend to be his girlfriend and she agreed.

A. What; that

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。6．—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。

7．________ 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。

8．______ amazed the NBA world is ______ Kobe Bryant scored 81 points just in one game.

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。9．________ has been proved is that animals and insects have their own languages.
