Question

【题目】

We were delayed at the airport. Otherwise, we_____ here by lunch time.

A. must be B. must have been

C. would be D. would have been

Answer 1

【答案】D

【解析】句意：我们在机场被延误了。要不然，我们就会在午饭时间已经到达这里。考查含蓄虚拟语气。Otherwise“否则，要不然”表示条件。Otherwise=If we had not been delayed at the airport。根据前面的were得知是与过去事实相反，所以主句中使用“情态动词+have done”。故D正确。
