Question

—Mary looks down today. What is up?
—Well，________happened between Mary and me is none of your business.

A．wherever

B．whoever

C．whatever

D．no matter what

Answer 1

C

解析试题分析：考察名词性从句。本句中的whatever happened between Mary and me引导的是一个主语从句。Whatever在句中作主语。D项不能引导名词性从句，A项不能在句中作主语。B项指人。故C正确。
考点：考察名词性从句
点评：主语从句是在复合句中充当主语的从句，通常放在主句谓语动词之前或由形式主语it代替，而本身放在句子末尾。解答这类题目，关键在于分析清楚句子结构。通过判断引导词在从句中所作的成分及意义，来选择正确的引导词。连接主语从句的从属连词主要有that, if, whether，和疑问词（what how where when ...)。that引导表示陈述句的主语从句，if和whether，whether...or not引导表示“是否”，引导一般疑问句。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.
