问题补充：

I ran across David while walking along the street yesterday. I him for three years.

A. hadn’t seen

B. didn’t see

C. haven’t seen

D. don’t see

答案：

(答案→)A. hadn’t seen

B. didn’t see

C. haven’t seen

D. don’t see

解析：句意：昨天我在街上走的时候碰到大卫。我三年没有见过他了。根据动词ran across和时间短语 yesterday，可知事情发生在过去，在遇见大卫之前有三年没见过他了，see 发生在ran across之前，故此处用过去的过去，即过去完成时。故选A。
