It is required that students mobile phones at school, so seldom them using one.

A. don’t use; will you see

B. should not use; you will see

C. not use; will you see

D. can’t use; will you see

答案：

A. don’t use; will you see

B. should not use; you will see

(答案→)C. not use; will you see

D. can’t use; will you see

解析：句意：学生们被要求在学校不能用手机，所以你很少看见他们用手机。

第一空require 所引导从句要用虚拟语气，should+do. Should 可省略。

第二空seldom 很少，否定副词置句首部分倒装。故选C。
