题目内容

Unfortunately, when I dropped in, Dr. Green ______, so we only had time for a few words.

A．just left

B．has just left

C．had just left

D．was just leaving

解析试题分析：考查时态：句意：不幸的是，当我拜访的时候，格林先生刚要走，所以我们只有时间说几句话。所以在我去的时候，格林先生还没走，ABC都不对，而是将要走，用过去进行时，表示过去将来时，选D。
考点：考查时态
点评：动词的时态要注意句中的时间状语。没有时间状语就要结合上下文把动作发生的时间找出来。这道题要弄清so we only had time for a few words. 说明格林先生还没走，是快要走了。
