问题 All flights __________(由于暴雪而被取消), many passengers could do nothing but take the train.
选项
答案having been canceled because of the snowstorm
解析 考查独立主格结构作原因状语以及语态。由于逗号之后是个完整的主谓句，之前如果没有关联词的话就需要用“逻辑主语+分词”形式，构成独立主格；frights和“取消”是动宾关系，所以用分词的被动态，并且“取消”发生在主句谓语动作之前，要用完成时，故答案为having been canceled because of the snowstorm。
