Question

【题目】(2017·天津卷) —Do you have Betty’s phone number?

—Yes. Otherwise, I ___________ able to reach her yesterday.

A. hadn’t been B. wouldn’t have been

C. weren’t D. wouldn’t be

Answer 1

【答案】B

【解析】句意：——你有贝蒂的电话号码吗？——有。否则我昨天就联系不到她了。此处otherwise(否则)相当于一个条件状语从句，由yesterday可知本句对过去进行虚拟，由此可以判断出主句用wouldn’t have done，故选B。
