Havingtakenourseats,______.A.theprofessorbeganthelectureB.thelecturebegan

Having taken our seats, ______.A.the professor began the lectureB.the lecture began in no timeC.we were attracted by the lecture immediatelyD.the bell announced the beginning of the lecture

C解析试题分析：句意：入座之后，我们立刻被演讲所吸引。根据Having taken our seats，这里用的主动可知，因为主句的主语与take之间是主动关系，所以主句的主语必须人，故排除BD，又根据句意故选C。考点：考查非谓语动词的用法。点评：本题难度适中。考查立意较低，主要考查的是非谓语的一些最基本的用法。但是，题目的设置注重了情景化和结构复杂化，加大了考生对题干句的理解难度。即学即练：When I got off the bus, I found my pocket _________ and the money gone.A. picked B. stolen C. missing D. lost解析：A。考查过去分词作宾语补足语的用法，pick one’s pocket表示“偷了某人的钱包”。宾语和宾语补足语之间形成被动关系。故选A项。
