选择题
(2013·安徽江南十校联考)—I regret ________ you that your application has not been successful.
—Not successful? I performed pretty well in my interview!
A．informing
B．to inform
C．having informed
D．to have informed
答案
答案：B
B 考查非谓语动词作宾语。句意：“我很遗憾地通知你你的申请没有成功。”“没成功？在面试中我表现得很出色呀！”当某一动作在regret之后发生时，regret后需加to do作宾语；当某一动作在regret之前发生时，regret后需加doing/having done/to have done作宾语。本句中inform后于regret发生，故选B。
