这里是虚拟语气表假设,虚拟语气有三种用法.
1.过去时
2.should+do
3. were to do

选B的话应该是if we left 而不是leave. 只有D 符合条件.

如果选B,后面不应该倒装,而应该we would be able to...

如果选B的话,前句并不是表虚拟,如果变成if we supposed to leave today还差不多。

考的是虚拟语气倒装

if引导虚拟条件句,与现在事实相反,条件句谓语用if...did/were,主句谓语用would/could/should do;与过去事实相反,条件句谓语用if...had done,主句谓语用would have done;与将来事实相反,条件句谓语用if...were to do/should do,主句谓语用would/should do。由后句would be可知,此处if引导虚拟语气,...

if引导虚拟条件句,与现在事实相反,条件句谓语用if...did/were,主句谓语用would/could/should do;与过去事实相反,条件句谓语用if...had done,主句谓语用would have done;与将来事实相反,条件句谓语用if...were to do/should do,主句谓语用would/should do。由后句would be可知,此处if引导虚拟语气,B项不是虚拟,首先排除。由句意:如果我们今天走,我们能在星期二到那吗?此处是对将来的假设,故选D。D项是省略了if的虚拟,将were提前构成倒装,were we to leave=If we were to leave。

收起

  答案选D

  该句使用的是虚拟语气,表示将来不太有可能或根本不可能发生的事,在虚拟条件状语从句中有三种表达:

  1. were to do

  2. did(过去式)

  3. should do
