问题补充：
It is reported that the bridge last year has been damaged in a terrible flood.
A. having been completed
B. to be completed
C. completing
D. completed
答案：
A. having been completed
B. to be completed
C. completing
(答案→)D. completed
解析：
试题分析:考查非谓语动词。分析结构可知此处是非谓语做定语，A选项现在分词完成时的被动形式不做定语；B选项是不定式做定语表示将来；C选项是现在分词的主动形式，表示主动意义，而D选项过去分词可以表示被动和完成，句中bridge和 complete之间是被动关系，而且根据last year 可知动作已经完成，由此判断D选项正确。句意：据报道去年建成的桥在可怕的洪水中受到了损坏。
