问题补充：

—Can I get my ears pierced, Mom? —No. As a student, you do that.

A. are allowed to

B. should be allowed to

C. may not

D. shouldn’t be allowed to

答案：

A. are allowed to

B. should be allowed to

C. may not

(答案→)D. shouldn’t be allowed to

解析：句意：我能打耳洞吗，妈妈？不行，作为一个学生，你不允许那么做。主语是you,和动词allow是被动关系，用被动语态be+动词过去分词；should应该，情态动词，后面动词用原形，shouldn’t be allowed to不被允许做……,故选D。
