should have prefered to 怎么理解？

We should have preferred to leave on the 8th , but outing to some reason we didn't.

请问：

1。should have prefered to 怎么理解？ “应该+已经愿意”为什么要用完成时态？它究竟是什么意思，猜测吗？

2。后半句实际没有离开，为什么反而不用完成时，只能过去时就可以了呢？

We should have preferred to leave on the 8th , but outing to some reason we didn't. （划线部分错误）

We should have preferred to leave on the 8th , but owing to some reason we didn't.（改为 owing to，也是错误）

We should have preferred to leave on the 8th , but for some reason we didn't.

should have preferred to do：（过去）本应该优先做某事（实际未做）。

we didn't：正好符合前文的意思，指过去没有。为什么要用现在完成时呢？

只解释语法啊（觉得这个句子怪怪的，看不清楚）

should have done是个固定的语法现象，大部分语法书把它归到虚拟里面，意思是“本来应该”，是对过去虚拟的，所以后面那句话是过去时。加个例句：

He should have handed in the schedule yesterday, but he didn't.他昨天就应该交上规划书，但没有。
