the water company were instructed to keep the people from****to the polluted water
A exposing B being exposed C exposing D being exposing
本题选择D.
但是我不明白为什么用被动的,难道A不可以吗?

the water company were instructed to keep the people from****to the polluted waterA exposing B being exposed C exposing D being exposing本题选择D.但是我不明白为什么用被动的,难道A不可以吗?
根据句意
阻止人们被暴露在污染水下
人们不可能是主动暴露在污染水下的

keep sb from doing sth 使某人避免做某事 所以用being
而又因为题意是避免使人们被暴露在污染的水中 用被动

防止人被污水接触,句子的意思是被动

这道题应该选B吧,being exposing语法是错的吧
