网友回答
A. is reported
(答案→)B. reported
C. reporting
D. which reports
解析：考查非谓语动词的过去分词作定语。分析句子结构，句子的主句是：Victimshave e up to 28.victims后带两个定语，一个是定语从句：who are infected with H7N9，一个是非谓语动词作定语，victims与report是被动关系，要用过去分词，故选B。当然也可用定语从句：which are reported in the news, A项没引导词，且主谓不一致，D项要用被动语态。句意：新闻报道，感染了H7N9的受害者人数达到28人。
