问题
选择题
I was caught in a traffic jam for over an hour, otherwise I ________ you waiting for such a long time.
A．will not keep
B．have not kept
C．had not kept
D．would not have kept
答案
答案：D
题目分析：句意：我被交通堵塞耽误了一个多小时，否则我就不会让你等这么久了。Otherwise相当于if I hadn’t been caught for over an hour，是和过去情况相反的虚拟条件句，主句用would have done，选D。
