选C。
5．_______ are playing an important part is well known to us all.A. That whoB. Those whoC. Who thatD. Who【答案】 D【解析】【分析】考查主语从句。
句意：谁起着重要作用，这是众所周知的。
主语从句缺少引导词，从句缺少主语，故选D。
6．--- made her ashamed of herself?--- the lowest mark in her class.A. What; Because she gotB. Was it what; GettingC. What was it that; That she gotD. 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。
7．____ he will offer us enough help doesn't matter a lot to our success.A. IfB. WhetherC. BeforeD. How【答案】 B【解析】【分析】句意：他是否提供帮助对于我们的成功没有什么关系。
If不可以引导主语从句，故选B。
【点评】考查名词性从句，本题涉及whether引导的主语从句的应用。
8．—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; thatB. it; thatC. it; becauseD. what; because【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。
9．They lost their way in the forest, and ___ made matters worse was that night began to fall.A. itB. whichC. thatD. what【答案】 D【解析】【分析】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。
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。
10．It is a rule in his family that _______ comes home first should cook the dinner.A. anybodyB. whoC. whoeverD. 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。
11．_______ you don't like him is none of my business.A. WhatB. WhoC. ThatD. 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。
12．________ the weather will not clear up until next week is bad news for us.A. AsB. IfC. WhetherD. 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。
13．________ has been proved is that animals and insects have their own languages.A. WhatB. AsC. ItD. That【答案】 A【解析】【分析】句意：已被证明的是动物和昆虫有自己的语言。
根据is判断，此处为主语从句，分析该从句，缺少主语，用what。
选A。
【点评】考查名词性从句，本题涉及what引导的主语从句的应用。
14．It was he said disappointed me.A. that; whatB. what; thatC. that; whichD. 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。
15．_______ caused the accident has not been found out yet.A. WhatB. WhichC. The thingD. That【答案】 A【解析】【分析】句意：造成事故的原因还没有查明。
此处为主语从句，从句中缺少主语，应该用what引导，故答案为A。
【点评】考查主语从句。
以及what的含义。
16．_______ has not been decided next.A. How to doB. What to do nextC. To do whatD. To do how【答案】 B【解析】【分析】句意：接下来做什么还没有决定。
根据助动词has可知前面是主语，what to do为名词性从句，可做主语，故选B。
