D. was ing
网友回答
A. e
B. came
C. am ing
(答案→)D. was ing
解析：句意为：那天过些时候我本会来拜访你的，但我打电话取消了。由but I had to phone and cancel.可以判断整句谈的是过去的事。A,C选项排除。透过句意可知I 站在过去的时间点来说将来，该用过去将来时。而英语中一些表示位置移动的动词（如e/go/fly/travel/arrive/等），常用进行时来表将来。所以选D.
【考点定位】动词时态的考查 e， go， leave， arrive， start等动词可用过去进行时代替过去将来时。例如：He said the train was leaving at six the next morning.他说过火车将于第二天早晨六点离开。She told me she was ing to see me.她告诉过我她要来看我。
