2、对所说的话进行强调。在小说的对话中，有时引述动词不用一般过去时，而用过去进行时，意在强调所说的话，语气较重，且更为生动。例句： A：“Did they catch her?”Mary was asking. “他们抓住她了吗？”只听得玛丽问道。 B:”No,she escaped.”Tom told her. “没有，她逃走了。”汤姆告诉她。

3、过去进行时还可和when结构遥相呼应，含有意外之意。例句： I was walking in the street when someone called me. 我正在街上走时突然有人喊我。

4、表示与现在事实相反或将来的猜想情况，有时表示不耐烦等情绪。例句： I was going to phone you,but I just didn’t have time. 我本想给你打电话的，但就是没有时间。 The basketball match was taking place the next day,but it had to be canceled because of the heavy rain. 篮球赛原定第二天举行的，但因大雨不得不取消。 I thought you were never coming. 我以为你总不会来了。

6、与always,constantly等词连用，表示感情色彩。例句: The girl was always changing her mind. 这女孩老是改变主意。

7、表示动作的未完成性。过去进行时可以表示动作的未完成性，即对某事了解的不全面，希望得到更详细的情况。例句： I was hearing Susan had entered the college. 我听说苏珊上了大学。

8、表示继续刚刚中断的谈话，用于日常生活中。例句： As I were telling you,the boy took his stubbornness from his father. 正想我刚刚告诉你的，这孩子的犟脾气是他爸爸遗传给他的。 As she was telling me,we must depend upon ourselves to make our own way as best we can. 正如她所告诉我的，我们必须依靠自己竭尽全力走自己的路。

1．过去进行时往往表示动作的未完成性，而一般过去时往往表示动作已完成。试比较：Davidwrotealettertohisfatherlastnight．大卫昨晚给他父亲写了一封信。(信写完了。)Davidwaswritingalettertohisfatherlastnight．大卫昨晚正在给他父亲写信。(指信在写的过程中，不一定写完。)2．过去进行时和always连用，表示赞扬、感叹、厌恶等感情色彩；而一般过去时和always连用,表示经常或反复发生的动作。试比较：Hewasalwayschanginghismind．他总是三心二意。(表示厌恶)Healwayswenttoworkbybuslastyear．去年他总是乘坐公共汽车上班。(表示经常性动作)3．一般说来，过去进行时侧重动作持续时间的长度；而一般过去时只说明过去某时发生某事，侧重说明事实。试比较：Itwasrainingheavilylastnight．昨晚下着大雨。(侧重说明下雨持续的时间长。)Itrainedheavilylastnight．昨天下了大雨。(侧重说明下雨这一事实。)4．在带有allnight,thewholemorning等强调时间长度的状语时，句中谓语动词用过去进行时更好些。如：HewasworkingallnightlastMonday．上周一他整整工作了一个晚上。5．在when引导的时间状语从句中，当when相当于while时，用一般过去时与过去进行时差异不大。如：IsawJohnwhenIwalked／waswalkingtothestation．我步行去火车站时看见了约翰。但当when分句中的谓语动词为一般过去，其主句用一般过去时或过去进行时，有时会引起时间关系的变化。试比较：Whenwearrived，shewasmakingsomefreshcoffee．我们到达时，她在调制咖啡。(分句动作发生时，主句动作已在发生．)Whenwearrived，shemadesomefreshcoffee．我们到达时，她调制了咖啡。(分句动作发生在主句动作之前。)6．有些表示状态、感觉、心理或情感的动词，如:be,have(有)，see,hear,know,think,believe,understand等，一般不用过去进行时，而用一般过去时。如：Ihadalotofworktodoyesterday．昨天我有许多工作要做。
