—I drove to Zhuhai for the air show last week.
—Is that__________you had a few days off?

A．why

B．what

C．when

D．where

答案

A

解析

试题分析：考查表语从句：句意：--我开车去郑州看空军展览了。--这就是你请假几天的原因吗？根据句意是why应该表语从句。What引导表语从句时，在从句中做主宾表，这句话已经有时间地点，不能用when和where，选A。
点评：连接表语从句的连接词有：that, what, who, when, where, which, why, whether, how, whoever，whomever，whichever ，whatever等。还有如because, as if, as though等。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。
