人教版中考英语专项训练名词性从句专项讲解及练习含答案解析

一、初中英语名词性从句

1．_______ 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。

2．While some behaviors may seem strange to you, remember you consider normal probably seems just as unusual to others.

A. it; that

B. what; that

C. that; what

D. which; that

【答案】 C

【解析】【分析】句意：虽然有些行为对你来说可能很奇怪，但请记住，你认为正常的行为对别人来说可能也不寻常。第一空为宾语从句，从句结构完整用that起连接作用，第二空为主语从句，从句中consider缺少宾语，应该用what，故选C。

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

3．_______ makes me feel worried is _______ singing stars are centered on by masses of teenagers today.

A. What; what

B. That; that

C. What; that

D. That; what

【答案】 C

【解析】【分析】句意：让我感到担忧的是，今天的歌星是以青少年为中心的。分析句子可知，主语从句中的谓语动词makes 缺少主语，主语从句中缺少宾语一般用what，因此选择 what 来引导主语从句；系动词 is 后面的表语从句句意完整，不缺少成分，因此选择 that 引导表语从句。分析选项可知C项符合题意，故选C。

【点评】考查名词性从句，本题涉及what引导的主语从句和that引导的表语从句的应用。

4．Exactly _________ the potato was introduced into Europe is uncertain, but it was probably around 1565.

A. whether

B. when

C. why

D. how

【答案】 B

【解析】【分析】句意：土豆被引进欧洲具体的事件不被确定，但是可能是在1565年左右。根据时间状语round 1565得知这里是指时间不确定。故选B。

【点评】考查名词性从句，本题涉及when引导的主语从句。

5．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】句意：他们在森林里迷路了，情况更糟糕的是天又黑了。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。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。

6．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。

7．______ is our belief that improvements in health care will lead to a stronger, more prosperous economy.

A. Which

B. What

C. It

D. As

【答案】 C

【解析】【分析】句意：医疗保健的进步将促进一个更强大、更繁荣的经济，这是我们的信念。that引导的是主语从句，故空格处应该用it作形式主语，代替真正的that引导的主语从句。故答案选C。

【点评】考查it的用法，以及主语从句的应用。

8．________ 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。
