Customers are about to make sure that they ___ the right change before leaving the shop.A will give B have been given C have given D will be given 这题我认为B.D都可选,但答案是唯一的,为什么?

选B,这句话表示的是顾客们被询问,确保他们在离开商店的时候已经找好了零钱.叙述的是顾客在离开商店的时候,顾客已经完成了购买活动,而再付钱的时候,肯定已经是找好了零钱（作为一种按照规定应该做的事情）,所以这里填have been given.个人的见解,不知能不能帮助楼主,如果觉得好就选我为满意答案吧,多谢了.这里改为are asked to 和about to相差不大,表达意思类似.如果回答正确,希望楼主选我为满意答案吧,多谢了.
