Question

On AIDS Day, President Hu Jintao demanded that the problems _________ paid special attention to.

1. A.
   referred to being
2. B.
   referred to be
3. C.
   refer to being
4. D.
   refer to be

Answer 1

B
考查虚拟语气和分词作定语。referred to为后置定语修饰the problems, 又因为demand引导的宾语从句引用虚拟语气，故谓语动词应该是should be，而should可以省略，所以答案为B。
