Mary couldn't have received my letter,otherwise she would have replied last week
这句话的后半句用的是虚拟语气,这句话不是从句吧?是不是从句的那种才符合虚拟语气的基本结构呢,我不明白为什么前面用could have done而后面用would have done呢,是不是用should have done 也行呢

这句话是一个含蓄虚拟的句子我给你阔展开你或许就明白了
mary couldn't have received my letter.if she had received my letter,she would have replied.
也就是说otherwise表达的意思应该是我上面的句子的意思与过去事实相反主句用would\should／could／might have done
