问题补充：

What a pity! When we got to the cinema，the movie The Assembly，so we saw only the end of it．

A. had just finished

B. was finishing

C. would finish

D. just finished

答案：

A. had just finished

(答案→)B. was finishing

C. would finish

D. just finished

解析：考查时态。句意：太可惜了！当我们感到影院使，电影《集结号》快要结束了（结束的动作正在进行），因此我们只看到部分结尾。结合语境可知下文描述的是某个时间正在进行的动作，故用过去进行时态，选B，原答案有误。
