本单元语法讲解
过去进行时（Past Progressive Tense）
句型 S + was/were +V-ing…
例A:She was doing her homework at 8:30 yesterday evening.
（昨天傍晚八点半她正在做家庭作业。）
例B:We were having supper at that time.
（那个时候我们正在吃晚饭。）
解说 如例1所示，在单句中使用过去进行时来表达时必须把该动作正在进行中的时间表明清楚，否则就不合逻辑了。例如：I was taking a bath yesterday. （错）
（昨天我正在洗澡--昨天24小时都正在洗澡吗？）
所以本句应该如例1来表达，或者用一般过去时表达如下：
I took a bath yesterday.（昨天我洗了澡。）
如果由上下文的文意，或者对谈中的话意可以了解“动作正在进行中的时间”，单句里就使用过去进行时来表达是很普通的，例如：
A:I called you up yesterday evening.
B:Did you? At what time?
A:At around ten o‘clock. （大约在十点钟。）
B:Oh， I was taking a bath then.（哦，当时我正在洗澡。）
过去进行时在表达上常用的句式是如例2所示和另一个一般过去时的动作相搭配。请观察下面的图解说明：
过去有二动作A和B（如图示），在B动作发生时稍早发生的A动作正好在进行中，所以这种表达法通常都是复句（主句+副词从句）。例如：
When I got up this morning， Mother was preparing breakfast in the kitchen.
（今天早上我起床时妈妈正在厨房里准备早餐。-“Mother…”是主句，“when…，”是副词从句。）
常用于修饰过去进行时的时间副词：过去的某一定点时刻（at + 过去的时刻），then （= at that time）（那时，当时），all + 时间，“When…/While…/As…”等副词从句，etc.
