题目内容
19. We were delayed at the airport. Otherwise, we here by lunch.
A. must have been B. could be
C. should be D. would have been
19. D考查虚拟语气。句意:我们在机场被耽搁了。否则,我们就能在午餐前到这里了。此处we were delayed at the airport是过去的事情,otherwise相当于一个虚拟条件句:If we hadn't been delayed at the airport.所以主句用would have done的形式。故选D。
