Question

—Can I get my ears pierced, Mom?

—No. As a student, you ________ do that

1. A.
   are allowed to
2. B.
   should be allowed to
3. C.
   may not
4. D.
   shouldn’t be allowed to

Answer 1

D
试题分析：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。
考点：考查情态动词与被动语态。
