单选题Itisrequiredthatthestudents______

单选题 It is required that the students ______ mobile phones in our school, so seldom ______ them using one.A.can’t use; will you seeB.not use; will you seeC.mustn’t use; will you seeD.shouldn’t use; you will see

B解析考查虚拟语气和倒装。It是形式主语，that the students ______ mobile phones in our school是主语从句，require后面的主语从句要用(should)+do的虚拟语气，所以排除A,C；seldom表否定意义，用于句首时，后面句子部分倒装，所以选B。

这个解释是对的
