【题目】The lecture ________, a lively question-and answer session followed.
A. being given B. had been given C. to be given D. having been given
在线课程【答案】D
【解析】
考查非谓语动词用法。句中逻辑主语lecture与动词give是被动关系，故需要用被动语态。being given指正在进行的演讲；to be given将要发表的演讲。having been given则强调时间先后，指的是此动作发生在谓语动词follow的动作之前。句意：发表演讲之后，接下来是现场提问时间。故C正确。
