A. What; that; what

B. What; what; what

从句中的动词understand缺宾语，要填what。故选A。

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。

--- 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。

14．_______ are playing an important part is well known to us all.

A. That who

B. Those who

C. Who that

D. Who

15．It________that the road will be closed tomorrow for repairs.

A. was announced

B. has been announced

C. had been announced

D. would be announced

【答案】 B

【解析】【分析】本题考查动词的时态和语态。题干句子中that到句子结束是宾语从句，且从句动词用“will＋动词原形”表示将来，由此推断出空白处谓语动词应用现在的某种时态，在所给四个选项中，只有B项正确。

【点评】考查现在完成时的被动语态，其结构是have/has +been +done。需要注意宾语从句的时态。主句用现在时，从句所需的任何时态。
