9.Unfortunately,when i dropped in ,proffesor smith( ),so we only had time for a few words.
A.has just left B.has just left
C.just left D.was just leaving
Q:have 时间发生在什么动作之前,是leave之前吗?用过去完成事态had+done,其参照点(过去的那个动作)不一定就用一般过去时态,还可以用哪些时态喃?最好有例句说明,thank you
D 写掉了我主要想问为什么题中是so we only had time for a few words,里要用过去完成时态.

正确答案是D
这里牵涉到三个问题：
1. 句意理解
so we only had time for a few words表示了Professor Smith当时还在,只不过即将离开；
2. 进行时表示“将要”
I'm leaving = 我要走了
I'm having dinner with Catherine = 我将要与Catherine共进晚餐
He's dying = 他快升天了
所以,Professor Smith was leaving = Smith教授要走了.而just补充修饰“正要”、“刚好要”的意思
3. 整句话的时态——不言而喻是过去时
这句话的意思是：可惜的是,当我到的时候,Smith教授刚好要离开,所以我们只能说了没几句话.
