问题 All flights ______because of the snowstorm, we decided to take the train instead.

选项 A、were canceled
B、had been canceled
C、having canceled
D、having been canceled

答案 D

解析 英语中两个或两个以上句子间一般都有连词来连接,以构成并列关系或从属关系,据此我们可以将A和 B排除。C和D都是现在分词短语,和all flights构成独立主格结构,作原因状语,又因为cancel 和all flights 具有逻辑上的动宾关系,所以应用被动式,因此C错误,而D正确。
