答案

C

解析

试题分析：考查定语从句和表语从句：第一空是定语从句，先行词是the reason，定语从句中gave缺少宾语，用that或which引导定语从句，第二空是表语从句：表示…的原因是…要用句型：(one)reason(for...)is that...句意：她迟到的原因是她忘记设定闹钟了。选C。
点评：定语从句的考查主要就是考查关系词的辨析，关系代词that, which, whose, whom, as， who在句中做主语，宾语，表语或者定语；where, why, when在句中做状语。要分析句子成分，看缺少什么成分，就选用相应的关系词。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。
