请问这道题选什么呢?为什么?
The goods _____ when we arrived at the airport.
A. were just unloading B. were just been unloading
C. had just unloaded D. were just being unloaded
选D
首先卸货应该用被动式,因为是货被卸.所以排除A、C,A选项是过去进行时的主动态;C选项若用被动则应为:had just been unloaded
其次:语意为“在我们到达机场时,货物正在被卸下来”,所以应用过去进行时:were/was being done
D
选C 、 后面的时间状语用的过去时态,前面所说的事就是发生在我们到达之前,是过去的过去,所以用过去完成时态
D
货物是主语,应用被动语态,所以A、B和C被排除
D、过去进行时
D 那时候,货物正被卸载
