【题目】I've heard that preparations _____ for the coming festival. Let's give them a hand.
A. are being made B. have been made
C. are making D. have made
在线课程【答案】A
【解析】句意：我听说为即将到来的节日正在进行准备活动，让我们去帮忙吧。根据题干“让我们去帮忙吧”，可知准备是正在被进行，所以选择A are being made 现在进行时的被动语态；B have been made 现在完成时的被动语态，表示“已经被准备完了”；C/D 都是主动。
