问题 The students ______busily when Miss Brown went to get a book she ______in the office.

选项 A、had written; left
B、were writing; has left
C、had written; had left
D、were writing; had left

答案D

解析 句意:当布朗小姐去取她忘在办公室的书时,同学们正奋笔疾书。本题考查谓语动词的时态。“把书忘在办公室”发生在“去取书”这一过去的动作之前,因此“忘了书”这一动作发生在过去的过去,应用过去完成时。句中when表示的是时间的一点,表示在“同学们正忙于……”这一背景下,when所引导的动作发生,因此主句应用过去进行时。
