31. The lecture, _____at 7:00 pm laze night, was followed by an observation of the moon with telescopes.
A. starting B. being started C. to start D. to be started
【答案】A 【解析】句意：报告于昨晚七点开始，报告之后便是用望远镜观察月球。start在此用作不及物动词（就像Classes start at 8 “8点开始上课”一样），瞬间动词的现在分词作定语表完成意义或将来意义：We shall arrive too late to catch the train leaving (=which will leave) at eight.我们会到达太晚了而赶不上8点（离开）的火车。A tile falling(=which fell)from a roof shattered into fragments at his feet.一片从屋顶上掉下来的瓦在他的脚边摔得粉碎。The accident happening to her turned out to be a good thing.她发生的意外证明\结果是件好事。
