一道虚拟语气的题目

We lost our way in that small village, otherwise we ____ more places of interest yesterday.
A. visited B. had visited C. would visit D. would have visited

我知道跟过去事实相反是用过去完成时，但是我不明白的是，什么时候是用情态动词的过去完成时，比如此题的D。什么时候用一般的过去完成时，比如C。
最后一句话错了，是
“比如B“

Answer 1

①与现在或将来事实相反，直接用情态动词+动词原形
②与过去事实相反，情态动词+一般完成时
有前半句We lost our way in that small village, 迷路发生在过去，
otherwise否则，就跟过去事实相反，满足情况②，所以就选D

追问

与过去事实相反为什么不用had visited？为什么一定要情态动词？

追答

had visited也是用于从句，作为对比的对象
虚拟语气的句子就需情态动词一块儿来够成这种语气
而这句话用了虚拟语气是otherwise。。。这句

Answer 2

D

因为你要表达一种过去已经完成的可能性 而不是过去发生的可能性

追问

请问两者的区别？可以详细点吗？

Answer 3

C是对现在和将来的虚拟，D是对过去的虚拟，此题应选D，C是过去将来时吧--
