10.As he approached the door,Mike looked into the room again to see if he _______ anything behind.( )A. | left | B. | had left | C. | has left | D. | would leave |
分析 当他走到门口时,有朝房间里看了一下,想看看是否落下什么东西了.
解答 答案:B 句中leave behind的动作发生在look into之前;look into用的是一般过去时态;leave behind的动作是过去的过去,要用过去完成时态.故选B.
点评 表示过去某一时间或动作以前已经发生或完成了的动作对过去的某一点造成的某种影响或是结果,用来指在另一个过去行动之前就已经完成了的事件.它表示动作发生的时间是"过去的过去",侧重事情的结果.
