问题 All flights______because of the strike, they had to find some other means of transportation.

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

答案A

解析 本题考查的是独立主格结构。本题中,独立主格结构做状语,由于是独立主格结构,因此选非谓语动词形式,先排除B、D两项。all flights是动作cancel的逻辑主语,两者之间的关系是动宾关系,即被动关系,因此要用被动语态,C项为主动语态。本句意为:因为罢工,所有的航班都被取消了,他们不得不寻找其它的交通出行方式。
