AIDS is said ___________  the biggest health challenge to both men and women in that area over the past few years.
A  that  it  is     B to be  C  that it has been   D  to have been

Answer 1

选D。be said.译为“据说”.over the past few years为完成时态的标志。所以排除A/B.
AIDS is said to have been the biggest health challenge to both men and women in that area over the past few years.
= It is said that AIDS has been the biggest health challenge to both men and women in that area over the past few years.
在过去的几年里，艾滋病已经成为了那一地区男性女性所面临的最大的健康挑战。

Answer 2

选择D
解析：首先be said后面有三种接法，1接that引导的从句；2接to do（此种情况一般表示将来的动作）；3接to have done（表示已经完成或还将持续的动作）
由题中over the past few years可知选择D。如果要用第一种用法，则正确的表达为：It's said that AIDS .....
