Question

—Late again ! Where_____? —Sorry,I____in the heavy traffic, or would have been here earlier.

Answer 1

D
翻译：——你又迟到了！哪儿去了你？
——对不起，路上大塞车，否则的话我会早点儿到的。
解析：第一个空用现在完成时（表示过去的行为动作对现在的状态造成的影响，也就是造成迟到的原因），第二个空用过去式，表示过去发生的事情，表示在我到达之前发生的事，所以用过去时态。or would have been here earlier是虚拟语气，完整的说应该是If I hadn't got stuck in the heavy traffic, I would have been here earlier.

Answer 2

—Late again !
Where are you?
—Sorry,I am in the heavy traffic, or would have been here earlier.
这是因为交通拥挤而又一次迟到的对话。
