— I didn’t go to class last night because my car broke down.
— You            mine. I wasn’t using it.
A.should borrowB.might have borrowed
C.could have borrowedD.must have borrowed
C

试题分析:考查虚拟语气。句意:因为我的车抛锚了,昨晚我没去上课。——你本可以借我的啊!我没有用它。可知选C,“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。might have done 是过去可能做了,must have done是过去一定做了。选C。
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/might+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。
