一、基本用法
过去进行时由“was / were 现在分词”构成,主要用于表示在过去某一时刻或某一阶段正在发生的动作。如:
I was having a bath when the phone rang. 我正在洗澡,突然电话铃响了。
While I was working in the garden, my wife was cooking dinner. 我在园子里干活时,我妻子正在做饭。
二、表示过去将来
正如现在进行时可以表示将来安排好的活动或事件一样,过去进行时也可以表示为过去的将来安排好的活动或事件。如:
He was busy packing, for he was leaving that night. 他那时正忙着打点行李,因为那天晚上他就要走了。
三、表示重复的动作
正如现在进行时与 always, constantly, continually 等副词连用可以表示重复的动作一样,过去进行时与这些副词连用也可表示过去重复的动作,并且也常常带有感情色彩。如:
When he worked here, Roger was always making mistakes. 罗杰在这儿工作时老出差错。
四、表示原因
过去进行时可用来申述原因或用作借口,这种用法在口语中比较常见。如:
She went to her doctor yesterday. She was having a lot of trouble with her skin. 她昨天去看病了。她的皮肤病还很重。
五、表示动作背景
过去进行时可用来为一个或一系列动作的发生提供背景。如:
He fell asleep while he was reading a newspaper. 他在看报时睡着了。
It was snowing as the medical team made its way to the front. 医疗队奔赴前线时,天正下着雪。
注:下面一句中的过去进行时也表示背景,但这种过去进行时常用在主句中,后接的 when 从句中的谓语动词常用一般过去时,表意外之事。如:
I was leaving the office when the telephone rang. 我正要离开办公室,电话铃响了。
