【题目】The lecture, ________ at 8:00 yesterday evening, was followed by an observation of the moon with telescopes.
A. being started B. starting
C. started D. to be started
在线课程【答案】B
【解析】考查非谓语动词。句意：昨天晚上八点开始讲座，在这之后是用望远镜观赏月亮。题干中was followed by是谓语动词，可以判定出空格出要使用非谓语结构；start与逻辑主语the lecture之间为主动关系，故此处用现在分词作后置定语，故选B。
