Question

【题目】By the time I got to school, the first play ________ for nearly half an hour.

A. has begun B. has been on C. had begun D. had been on

Answer 1

【答案】D

【解析】

考查时态。句意：当我到达学校的时候，第一场比赛已经持续了将近半个小时。根据By the time引导的从句，可知句子用过去完成时态，再根据for nearly half an hour，说明此处应该用持续性动词，begin是终止性动词，后面不能跟一段时间，故选D。
