However frequently, the works of Shakespeare always attract many people.

A. performed

B. performing

C. being performed

D. to be performed

答案：

(答案→)A. performed

B. performing

C. being performed

D. to be performed

解析：考查非谓语动词。perform和the works之间是动宾关系，应该用过去分词，排除B；句意：无论被演过多少次，莎士比亚的作品总是能吸引很多人。根据句意可知，C表进行；D表将来，都不合适。故选A。
