A. discussed
B. were discussing
C. have discussed
D. was discussing
答案:
A. discussed
B. were discussing
C. have discussed
(答案→)D. was discussing
解析:句意:当我们进入房间时, 这位老师兼作家及一些学生正在讨论某事。 “A +aswellas+B”结构作主语时,句子谓语与A 保持一致。此 处主语“Theteacherandwriter(老师兼作家)”指 一个人,故谓语用单数。因为时间状语从句是when we entered the room.故用过 去进行时。选D。
