【题目】A total number of 172 people are now in hospital for treatment, of them 24 seriously ________.
A.being injuredB.injuredC.having injuredD.to be injured
在线课程【答案】B
【解析】
考查非谓语动词。句意：目前共有172人在医院接受治疗，of them 24 seriously ________为独立主格结构做伴随状语，其中24人严重受伤。24后省略名词people，与injure之间为被动关系，所以用过去分词，相当于 and of them 24 seriously are injured 。故选B。
