专项训练名词性从句专题复习含答案解析
一、初中英语名词性从句
1．--- 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。
2．It was he said disappointed me.
A. that; what
B. what; that
C. that; which
D. which; that
【答案】 B
【解析】【分析】句意：正是他说的话让我很失望。这是一个强调句型,"it is/was that..."是固定搭配,"what he said"是被强调部分, 你可以发现去掉"it was that"后, 句子仍然完整。"what he said"做主语,主语从句中"said"缺宾语用what补足，故选B。
【点评】考查主语从句的强调形式。
3．They lost their way in the forest, and ________ made matters worse was that night began to fall.
A. it
B. which
C. that

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。
5．______ 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。
6．________ the weather will not clear up until next week is bad news for us.
A. As
B. If

【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。
7．_______ 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。
8．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。

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。

B. What; that; what
C. That; because; that
D. What; because; which 【答案】 B
【解析】【分析】句意：珍妮最兴奋的是对他来说似乎是最困难的考试，她终于成功了。______excited Jenny most是主语从句，从句中缺少主语，因此用关系代词what ；_____ she finally succeeded in ...是表语从句，从句中不缺少成分，因此用引导词that；______seemed to be the most difficult exam to him.是宾语从句，从句中缺少主语，因此用关系代词what ，故选B。

【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。
