1. I am writing to explain why I was _________your lecture last time.
A. absorbed at B. absent from C. absurd in D. accurate at
【答案】B
【解析】
【详解】考查固定短语词义辨析。句意：我写信是想解释一下我上次缺席你讲座的原因。A. absorbed at全神贯注于……；B. absent from缺席……；C. absurd in在……方面感到荒谬；D. accurate at在某方面精确。根据空后“your lecture ”和空前动词explain可知，空处需用absent from，表示缺席讲座。故选B。
