选择题
It is required that the students ______ mobile phones in our school, so seldom ______ them using one.
A.can’t use; will you see
B.not use; will you see
C.mustn’t use; will you see
D.shouldn’t use; you will see
答案
答案:B
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。
