C. has been dead , dead
D. has been dead, death
答案：
A. died, dead
B. died , death
C. has been dead , dead
(答案→)D. has been dead, death
解析：句意：他已经死了有两年的时间了，对于他的死我们仍然很悲痛。die 动词，例如Im dying 我将要死亡dead 形容词，例如my sister is dead我姐去世了death名词 例如his death made me sad他的死让我伤心，for+一段时间用完成时，而且谓语动词必须表状态或持续性的所以用be dead,完成时用have/has been dead,his +名词。根据题意故选D
