题型:不详难度:来源:
Sorry I’m late. I ____ have turned off the alarm clock and gone back to sleep again.
A.mightB.shouldC.needD.will

答案
A
解析

试题分析:考查情态动词+have done的用法:might have done sth. 是常用句型,表示在过去可能做了什么。should have done 本应该做某事,句意:也许我可能把闹钟关了 然后又重新睡觉了 所以迟到了
点评:情态动词用于推测和虚拟语气连用一直以来都是高考的重点,对过去情况的推测虚拟语气要用情态动词+have done,具体的意思根据情态动词来判断。指过去情况对推测和虚拟,should have done本该做…而没做,shouldn’t have done本不该做…而做,Must have done过去一定做了might have done过去可能做了。
