qubie

① 过去进行时强调动作在过去某时刻正在进行或持续，而一般过去时表示动作的完成。如：

He was writing his composition last night.

他昨晚在写作文。(不一定写完)

He wrote his composition last night. 他昨晚写了一篇作文。(已经写完)

②表示过去的状态、感觉及心理活动的静态动词(如be， like， love， hate， fear， own， hear， see， know， want， notice)可用于一般过去时，但通常不用于进行时。如：

I hated it when a man spoke with his mouth full of food.

我讨厌人们说话时口里含着食物。

③ 一般过去时与always， constantly， forever， continually等连用，表示“过去经常性、习惯性的动作”;而过去进行时与always， constantly， forever， continually等连用，表示动作的重复，常带有感****彩。如：

He always got up at six.

他过去总是六点起床。

He was always thinking of his work.

他总是一心想到工作。

He was always thinking of others.

他总是想到别人。

④有时过去进行时可以用来替换一般过去时，但一般过去时表示主语的行为是经过认真考虑的;而过去进行时表示一种较随便或没有进行仔细考虑的行为。如：

I thought that he would agree with us.

我原以为它会同意我们的。

I was thinking of persuading him to follow my advice.

我想到了要说服他接受我们的建议。

⑤过去进行时可表示按计划、安排过去某时刻将要发生的动作。如：

He said they were leaving for Beijing this afternoon.

他说他今天下午要去北京。

⑥动词hope, wonder等的过去进行时常用来表示提出要求，虽然表示现在的内容，但语气比一般现在时或一般过去时要委婉。如：

I was wondering whether you could come to join us.

我想你能否过来跟我们一起活动?

注意：
