had you listened to the doctor you ---- all right now 为什么选would be而不是 would have been

问题描述:

had you listened to the doctor you ---- all right now 为什么选would be而不是 would have been
额 我想知道 为什么有那个now ,就能知道用would be 你而不是别的?would be和现在也不挨边啊,

虚拟语气,had you listened to the doctor 是对过去的假设,主句是对现在的虚拟,现在的虚拟Should、Would、Could+动词原形.
