When Henry was trying to find the snake, his hand began to hurt badly.
I was trying to pick it up when it bit me again. 基本概念：过去进行时表示在过去某一时刻或某一段时间内进行或发生的动作。
基本结构
主语+was/were + doing +其他内容

注:doing 就是现在分词，词形变化与现在进行时相同过去进行时常用的时间状语：this morning, the whole morning,
all day yesterday, from nine to ten last
evening, when, while , at that time,
just now常见的句式　肯定句：
主语+was/were +doing +其它
　否定句:
主语+was/were +not +doing +其它
一般 疑问句:
Was/Were+主语+doing+其它
　 特殊疑问句:
特殊疑问词+was/were+主语+doing+其它用法：　
1. 过去进行时的基本用法主要表示过去某一时间正在进行的动作。 如：
He fell asleep when he was reading.
他看书时睡着了。
2. 过去进行时表示现在，主要是为了使语气委婉、客气。 如：
I was wondering if you could give me a lift.
我不知你能否让我搭一下车
【注】一般过去时也有类似用法，但比较而言，用过去进行时显得更客气，更不肯定。
3. 过去进行时表示感彩与现在进行时相似，过去进行时也可表示满意、称赞、惊讶、厌恶等感彩，也通常与 always, forever, continually等副词连用。 如：
They were always quarrelling.
他们老是吵架。 4. 动词be的过去进行时也可表示过去一时的表现或暂时的状态。
比较：
He was friendly.
他很友好。 (指过去长期如此)
He was being friendly.
他当时显得很友好。(指当时一时的表现) 通过上一模块的学习，我们知道过去进行时可以表示过去某一时刻或时段正在进行或持续的动作，句子常和 at?... yesterday morning, at that time, at?... last night 等时间状语连用。其实，过去进行时还可以和 when, while, as 引导的过去时间状语从句连用，形成复合句。 过去进行时（2）(1)?While the lights were changing to red, a car suddenly appeared round the corner.?
正当交通信号灯要变成红灯的时候，一辆小轿车突然从拐角处驶出来。
(2)?One day, when Henry was working in a restaurant, a snake suddenly appeared.?
一天，当亨利正在餐馆里工作时，一条蛇突然钻了出来。(3)?I was trying to pick it up when it bit me again.?
我正试图捡起它（那条蛇），突然它 ( 蛇）又咬了我一口。
(4)?As the doctors were checking him, the pain got worse.?
医生给他做检查时，疼痛加剧了。 下面，让我们来分析 when 和 while 从句与过去进行时连用的几种情况。
1. when 所引导的时间状语既可以指时间点，也可指时间段；while 所引导的时间状语只指时间段。因此，在 when 引导的时间状语从句中，动词可以是终止性动词，也可以是延续性动词；而在 while 从句中，动词必须是延续性动词。例如： They arrived while we were having dinner.?
我们吃饭的时候他们到了。
这句话还可以写成：
They arrived when we were having dinner.2. 由 when 引导的时间状语从句，如果主句用过去进行时、从句用一般过去时，则表示一个动作正在进行的时候另一个动作（突然）发生了，强调后一动作发生的突然性。请看例句：
We were talking when the teacher came in.?
我们正在讲话，老师（突然）进来了。 该句也可以用 while 表达，但与用 when 表达有细微的区别，请注意体会：
While we were talking, the teacher came in.?
我们正在讲话的时候，老师进来了。（只表明老师进来的事实，不强调突然性）3. 当主句和从句的动作都是延续的或同时发生的，两句都用过去进行时的时候，多用 while 引导。例如：
They were singing while we were dancing.?
他们在唱歌，我们在跳舞。 一般过去时与过去进行时的区别 1、一般过时往往表示某一动作已经完成，而过去进行时却表示动作在持续或未完成。
　比较：
She wrote a letter to her friend last night.
她昨晚给朋友写了封信。 (信写完了)
She was writing a letter to her friend last night.
她昨晚一直在给朋友写信。 (信不一定写完) 2、一般过去时表示只做一次动作，而过去进行时却表示动作反复地进行。
如：
She waved to me.
她朝我挥了挥手。
She was waving to me.
她一直朝我挥手。 3、句中有a moment ago之类的短语一般用一般过去时。
4、句中有at this time last Sunday, from 8 to 9 yesterday 之类的状语一般用过去进行时。过去进行时可以用来代替一般过去时，表示更为偶然而非预定的动作：
I was talking to Tom the other day．
那天我跟汤姆聊天来着。 典型的例子 1) Mary ___ a dress when she cut her finger.
A. made B. is making
C. was making D. makes
答案 C. 割伤手指是已发生的事情，应用过去时。同 时，when表时间的同时性， “玛丽在做衣服时”提供事情发生的背景，因此用过去进行时。 2) As she ___ the newspaper, Granny ___ asleep. A. read; was falling
B. was reading; fell
C. was reading; was falling
D. read; fell
答案B.句中的as = when, while，意为“当……
之时”。描述一件事发生的背景时，用过去进行；
一个长动作发生的时候，另一个短动作发生。句
意为 “在她看报纸时，奶奶睡着了。 ”句中的
fell (fall的过去时)，是系动词，后跟形容词，
如：fall sick。1 Complete the sentences with when or while.1 He was listening to music he was riding his

My friend Jack was always having accidents. He did not pay attention to where he was going or what he was doing.
A few months ago, a car hit him while he was on his way home from school. The driver was a bit tired, so he did not see Jack. And Jack was talking on his mobile phone and was riding in the middle of the road. The car hit him. He broke his leg and was in hospital for over a month.
Last week, he fell down a hole in the park. As usual, he was not looking where he was going. Some kind-hearted people in the park helped him climb out of the hole and then took him to hospital because he was in a lot of pain. Luckily, he did not break an arm or a leg. At the hospital, the doctors gave him some medicine and then he went home.
I always told him to be careful, but he did not listen to me. After the two accidents, he promised to take my advice. Now he is very careful.
