Do you have any idea ___ is actually going on in the classroom? A．that B．what C．as D．which

Answer 1

B

试题分析：考查同位语从句。本题同位语从句what is is actually going on in the classroom用来解释名词idea的内容。What在句中做主语。That引导同位语从句，在句中不充当任何成分，只起连接作用。句意：你知道在教室里发生的事情吗？故B正确。 点评：解答这类题目，关键在于分析清楚句子结构，知道引导词的使用习惯。通过判断引导词在从句中所作的成分，来选择正确的引导词。连接同位语从句的从属连词主要有that, if, whether，和疑问词（what how where when ...)。that引导表示陈述句的同位语从句，if和whether，whether...or not引导表示“是否”的一般疑问句的同位语从句。连接代词主要有who,whom,whose,what,whoever,whomever,whosever,whatever,whichever等。连接代词一般指疑问，但what, whatever除了指疑问外，也可以指陈述。连接副词主要有when, where, why, how, whenever, wherever, however等。
