Question

_A_if I had arrived yesterday without letting you know beforehand?

A. Would you be surprised B. Were you surprised
C. Had you been surprised D. Would you have been surprised
为什么选A？跪求解释啊！

Answer 1

这个句子是虚拟语气，if条件句中是对过去的虚拟，用过去完成时，主句是对将来的假设，用would加动词原形，所以选A。其中B选项是陈述过去的事实，C陈述过去的过去的事实，D是对过去的虚拟

Answer 2

虚拟语气的一种：如果表示与现在事实完全相反的假设，条件从句与结果主句的动词形式分别为：条件从句（过去式） 结果主句（should、would、could、might+动词原形）即选A

Answer 3

谁给你的答案？这题选d才对。主句用过去完成，所以从句用would have done，由于是被动语态所以再加个been 。 然后疑问句时be动词提前。所以选d
