5．--- made her ashamed of herlf?
--- the lowest mark in her class.
A. What; Becau she got B. Was it what; Getting
C. What was it that; That she got D. What was it that; Getsmart意思
【答案】 C datetime
【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becau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。

【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。
