题目内容
1．Andrew ______ the task within two months．But he didn't，so he was fired．（ ）| A． | finished | B． | must finish | ||
| C． | should have finished | D． | would have finished |
分析 句意：安德鲁本应该在两个月之内完成任务的，但是他没有，因此他被开除了．
解答 答案C．由"he was fired"可知，事情发生在过去，故用情态动词+have done表示对过去的推测．"should have done"本应该做某事而没做；"would have done"本来会做某事而没做．根据句意，安德鲁本应该在两个月之内完成任务的，但是他没有，因此他被开除了．故选C．
点评 本题考查情态动词+have done的用法，要掌握其用法并结合具体的语境选择出正确的选项．
