If they _____(not bring)to the surface soon they may lose their lives.
这是我在一本资料里遇到的题目，答案是are not brought，我想不懂为啥，

don't bring 这是由If 引导的条件状语从句,应当用主将从现.主句中如含有情态动词,如 may,can,must等也可看作一般将来时态,那么从句用一般现在时态的don't bring 来表示
再问：我也这么觉得，可是书上的答案是are not brought，想不明白啊
再答：很抱歉。是我的错。没有认真看题。这是一个被动语态的题。意思是：如果他们不能很快带到水面，他们会死的。如果是被动语态这里当然要用be done 就是are not brought. 再次表示我的歉意，希望这次对你有帮助
