英语名词性从句试题类型及其解题技巧

一、初中英语名词性从句

1．________ 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。

2．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。

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．In the past decade, our education system too much on grades. However, grades have a direct connection with future success is still a question.

A. focused; whether

B. focused; if

C. has focused; whether

D. has focused; if

【答案】 C

【解析】【分析】考查时态和主语从句。根据In the past decade,在最近的几十年里，可知

句子用现在完成时态，our education system是句子的主语，单数形式，所以第一空填has focused；第二空是主语从句做主语，if是否，不能引导主语从句，所以第二空填whether。故选C。

【点评】主语从句主要有三类：

1）（1）由连词that引导的主语从句:引导词that无含义,在句中不做成分,不可以省。例如：That you will win the medal seems unlikely.你想获得奖牌看起来是不可能的。（2）用连词whether 引导的主语从句:whether有含义（是否）,在句中不做成分,不可以省。例如：Whether she is coming or not doesn't matter too much.她来不来都无关紧要。注意：if不能引导主语从句。

2）用连接代词引导的主语从句（在由连接代词who, whose, whom, which, what, whoever, whomever, whichever, whatever引导的名词性从句中，其连接代词在句中起名词性作用，担当一定成分）.例如：What you need is more practice.你所需要的是更多的训练。

3）用连接副词when, where, why, how引导的名词性从句（其连接副词有含义,在句中作状语。）例如：Where we should leave it is a problem.

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

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。

6．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。

7．______ 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。

A. that

B. it

C. what

【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。
