---Why didn’t you reared him of the possible danger?
---But what       otherwise? He never listens to me.
A.could I doB.could I have doneC.should I doD.must I have done

答案
B
解析

试题分析:考查虚拟语气:句意:——你为什么不告诉他可能的危险?——但是告诉他又能怎样?他从来不听我的。otherwise相当于if I had reminded him of the the possible danger可知是和过去事实相反的虚拟语气,要排除A和C。must have done是对过去的事情的推测,could have done可以是对过去的虚拟。选B。
点评:在虚拟语气中,有时假设的情况并不是以条件状语从句的形式表示,而是通过相应的介词或连词来表示,如 without, but for, or, but, otherwise 等。
