可不可以说得简单一点？我只是个初中二年级的学生。
简单点，那现在完成时学过吗？这个短语就是动词hear的现在完成体的ing形式，做时间状语，强调这个动作已经发生或完成。
现在分词的完成式
现在分词的完成式主要用在状语中，表示这个动作在谓语所表示的动作之前完成。
【例如】
Having succeeded in the last examination, she was more confident of another success in the coming one.
Having found the cause, they were able to propose a remedy.
Having finished his homework, the boy went to play computer game.Notshavingsmade adequate preparations, they thought it better to postpone the excursion till next week.
独立结构中也可以用现在分词的完成形式。
【例如】
His parentsshavingsdied, the orphan is now taken care of by the government.
The guestsshavingsleft, they resumed their discussion.
having heard,这里是做非谓语！
