It’s required that the students mobile phones in their school, so seldom _ them using one.

A. not use; will you see

B. should not use; you will see

C. don’t use; will you see

D. would not use; you will see

答案：

(答案→)A. not use; will you see

B. should not use; you will see

C. don’t use; will you see

D. would not use; you will see

解析：考查虚拟语气和倒装句。动词require后面的宾语从句要使用should+动词原形，should可以省略；第二空的“so+形容词/副词”放在句首，后面的句子要使用部分倒装的形式。句意：在这所学校里，要求学生不带手机，所以你很少能看见学生使用。故A正确。
