解析
试题分析:考查情态动词的用法,因为说的是昨天的事,用情态动词+have done,它们指的都是过去的情况,should have done本应该做而没做,may have done本可以做,句意是:对不起,我本应该昨天把自行车还给你的,但我太忙了。选B。 点评:情态动词+have done可以表示推测和虚拟:“must+have+done”表示对过去事情的肯定推测,译成“一定做过某事”,该结构只用于肯定句。“can"t+have+done”表示对过去事情的否定推测,译成“不可能做过某事”。“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。“could+have+done”是虚拟语气,表示对过去事情的假设,意思是本来能够做某事而没有做。 “would+have+done”虚拟语气,表示对过去事情的假设,意思是“本来会做”。 |
