A. referred to being

B. referred to be

C. refer to being

D. refer to be

答案：

A. referred to being

(答案→)B. referred to be

C. refer to being

D. refer to be

解析：考查过去分词作定语和虚拟语气。句意：在艾滋病日那天，卫生部部长要求被提到的那几个问题应该特别注意。分析句子结构可以得知referred to作后置定语，修饰problems；谓语动词demand后面的宾语从句的谓语动词要用“should+动词原形”，should可以省略。选B。
