— I haven’t finished my task yet. — You shouldn’t have watched the film last night or you

问题补充：

— I haven’t finished my task yet.

— You shouldn’t have watched the film last night, or you it by now.

A, need have finished B. may have finished

C. should have finished D. will have finished

答案：

解析：考查虚拟语气。“may+have+done”表示对发生过的事情的推测，意思是“可能已经”或“也许已经”，用于肯定句中。“need+have+done”表示本来需要做某事而没有做。“should+have+done”意思是“本来应该做某事，而实际没做。句意：我还没有完成我的任务。——昨晚你不应该看电影，否则到如今你可能已经完成了。故选B。
