句结构上的区别
• 1．一般过去时的否定句、疑问句多是借助助动词did来体现的(be的疑问句和否定句除 外)，需要注意的是：此时实义动词应用原形。如：
He worked in Beijing last year． 否定句：He didn＇t work in Beijing last year．
• 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：
It was raining heavily last night． 昨晚下着大雨。(侧重说明下雨持续的时间长。) It rained heavily last night．
昨天下了大雨。(侧重说明下雨这一事实。)
疑问句：Did he work in Beijing last year﹖
反意疑问句：He worked in Beijing last year, didn＇t he﹖
2．过去进行时的否定句、疑问句多是借助系动词was或were来体现的(和动词be一般 过去时的疑问句和否定句一样)。如： He was working in the park at eight yesterday morning． 否定句：He wasn＇t working in the park at eight yesterday morning． 疑问句：Was he working in the park at eight yesterday morning﹖ 反意疑问句：He was working in the park at eight yesterday morning, wasn＇ t he﹖
• 2. It’s high time we＿cutting down the rainforests. A. Stopped B. had to stop C. shall stop D. stop 答案：A
解析：It is (high) time (that)后面的从句谓语动 词要用过去式或“should＋动词原形”，且 should 不能省略
2．过去进行时的形式结构为：
主语＋was／were＋动词的现在分词＋其它。如： What were you doing this time yesterday﹖
昨天的这个时候你在做什么？
He was drawing an elephant on the blackboard when the teacher came in． 当老师进来时，他正在黑板上画一头大象。
一般过去时与过去进行时差异不大。如：
I saw John when I walked／was walking to the station． 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： When we arrived， she was making some fresh coffee． 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．) When we arrived， she made some fresh coffee． 我们到达时，她调制了咖啡。(分句动作发生在主句动作之 前。)
Exercise
• 1.James has just arrived, but I didn’t know he＿until yesterday. A. will come B. was coming C. has been coming D. came 答案：B
解析：本句是在过去时间里（昨天）看将来动作 （詹姆斯要来），应该用过去将来时。因为 come/go/leave一类的进行时可以表将来，was coming 表达的就是过去将来时。
6.故事的开头常常用过去进行时，来描述一种情 景或提供一个故事的背景。 如:It was a dark night. The wind was blowing hard and the rain was falling heavily. 7．表示方向或位移的动词，如：come, go, leave, start, return, arrive, stay 等，用过去 进行时，以表示按原计划或按原安排即将发生 的某一动作。如： • He said he was leaving home for a holiday. • I knew she was coming to our English evening.
• He would have finished his college education, but he＿to quit and find a job to support his family. A. had had B. has C. had D. would have 答案：C 解析：他辍学是真，而且已经发生，所以 用过去式。has to过去式是had to, 没有过 去完成时had had to 这种说法，所以选C
4．在带有all night, the whole morning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： He was working all night last Monday．
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
用法上的区别
• 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：
David wrote a letter to his father last night． 大卫昨晚给他父亲写了一封信。(信写完了。) David was writing a letter to his father last night． 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： He was always changing his mind． 他总是三心二意。(表示厌恶)
8. 英语中有四类动词一般不用进行时（不用现在进行 时和过去进行时） 1）表心理状态、情感动词： love ,hate ,like ,care ,respect ,please ,prefer , know 等 若用进行时则词意改变 I’m forgetting it . (=beginning to forget ) 2) 表存在、状态 appear ,exist ,lie ,remain ,stand ,seem 等 3) 表感觉的动词see ,hear ,feel ,smell ,sound ,taste . 4) 表一时性的动词 accept ,allow ,admit ,decide ,end ,refuse ,permit ,promise等。
