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
excel学习【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。

2．It has been pointed out ________ plays a vital role in driving away one's anxiety is one's
sweet childhood memories.
A. what that B. which C. that D. that what
【答案】 D
【解析】【分析】句意：有人指出，驱除焦虑所起着至关重要的作用是童年美好的回忆。本句时一个主语从句，it作形式主语，真正的主语为that what plays a vital role in driving away one's anxiety is one's sweet childhood memories.，主语从句中又有一个主语从句，且此主语从句中缺少主语，所以用what引导。故选D。
【点评】考查名词性从句，本题涉及what引导的主语从句。
3．Some people believe _______ has happened before or is happening now will repeat itlf in the future.
正常指甲图片A. whatever B. whenever C. wherever D. no matter what装饰工
【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. What; that B. That ; that C. What; whether D. It; that

5．They lost their way in the forest, and ___ made matters wor was that night began to fall.
A. it 敲咚咚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 wor，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。
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．______ 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．____________ 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．_______ makes me feel worried is _______ singing stars are centered on by mass 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。
