【点评】考查名词性从句和定语从句，本题涉及固定句式it is known to us all that…和whom引导的限制性定语从句。

【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。

A. What; that B. That ; that C. What; whether D. It; that 【答案】 A

【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。

【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。

A. what do kids like B. what kids like C. what are kids like D. what kids are like 【答案】 D
【解析】【分析】句意:我知道他对一切充满好奇，但那是小孩的样子。耐心点儿。That's后跟的是一个表语从句，从句要用陈述句语序，所以A,C错了B. what kids like那是孩子喜欢的东西，D. what kids are like那是小孩的样子.对一切充满好奇是小孩的行为，故选D like，动词，表示喜欢，有时态变化形式;be like表示像，like是介词，like没有词形变化。这是中考的常考点。
