Question

We spent hours driving and another few hours waiting, only _________ that the plane would be delayed until midnight.

A．to be told

B．having told

C．to have been told

D．told

Answer 1

A

试题分析：考查不定式用法。only to do sth. 的意思是“不料，竟然”；C选项是不定式的完成式，表示动作发生在谓语动词之前。句意：我们开车好几个小时，又等了好几个小时，结果却被告知飞机被延误到半夜。故A正确。
点评：本题考查的非谓语动词做结果状语的用法。不定式与only连用表示意料之外的结果，现在分词则表示的是意料之中的结果。
