问题补充:
Having finished her project, she was invited by the schoolto the new students.
A. speaking
B. having spoken
C. to speak
D. to have spoken
答案:
A. speaking
B. having spoken
(答案→)C. to speak
D. to have spoken
解析:句意为:完成既定项目后,她被学校邀请去给新生发言。Invite sb to do sth 邀请某人做某事且speak的动作显然发生在finish和be invited之后。所以用不定式的一般式。
【考点定位】考查非谓语形式作宾语的用法。doing 主动且进行 having dong 主动且完成(发生在主干动作之前)to do 未发生 to have done 将来且完成(发生在主干动作之后)。
