为什么不能选C

解题思路： 现在分词用作状语解题过程： ___the cry for help, people immediately rushed out of the rooms。 A。 To hear B。 Hearing C。 Having heard D。 They hearing 句意为：一听到求救的喊声，人们立刻冲出了房间。分析句子语意可知，people与hear之间存在主动关系，所以确定参选答案为B项或C项，Hearing表示与谓语动词rushed的动作几乎同时发生，一听到就冲出去了，符合常理；而having heard强调其动作发生在谓语动词之前，有时间间隔，用在此句中不符合语境。 这样的句子就可以用现在分词的完成式： Having worked in France for two years, he returned to his motherland。 Having waited for a long time, he remembered leaving his wallet at home。 明白了吗？若有疑问请继续添加讨论啊，祝你周末快乐！！最终答案：略
