【题目】Jane can’t have the meeting at 3 o’clock this afternoon because she _________ a class at that time.
A. will teach
B. would teach
C. has taught
D. will be teaching
在线课程【答案】D
【解析】试题分析：句意：简不能参加今天下午3点钟的会议，因为她那个时候在一个班上课。根据句中的时间状语at that time，指代at 3 o’clock this afternoon，表示在将来的某一时刻正在做某事，故用将来完成时。故选D。
