不错哦 While the boy was taking photos, the UFO took off. 当男孩在照相时, UFO起飞了。 The weather was fine while we were in Beijing. 当我们在北京时天气很好。 注：如果主句的动作在从句的动作过程中发生，从句常用进行时。 While we were swimming someone stole our clothes. 当我们在洗澡时有人偷了我们的衣服。 Don't talk so loud while others are working. 当其他人在工作时不要大声喊叫。 ■表示两个同时持续的动作。 I was doing my homework while he was listening to music. 我在做作业而他在听音乐。 注：通常不能用于过去进行时的动词主要有：agree, is, am, are, believe, belong, care, forget, hate, have (拥有), hear, know, like, love, mean, mind, notice, own, remember, seem, suppose, understand, want, wish等。 【用法点拨】 对于初二学生来说，熟练掌握过去进行时的构成、意义、标志词和过去进行时的各种句式是很容易在英语考试中取得高分的，但是要掌握好一般过去时与过去进行时的区别，when 与while的不同之处，也是需要下一番功夫的，这需要在大量的习题中掌握其技巧，但只要牢记when 与while的这两种从句，即：主句（过去进行时）＋ when + 从句（一般过去时），主句（一般过去时）+ while +从句（过去进行时）对于做题也是很有用的。 关于过去进行时的考查，总结常见题型如下： Ⅰ. 句型转换 (1) We were listening to the teacher when she came in. (对划线部分提问) _____ _____ you _____ when she came in? (2) He does his homework every day. (用at this time yesterday改写句子) He ____ _____ his homework at this time yesterday. 以上（1）小题是对过去进行时句式改变的练习，只需照以上讲解完成即可。(2)小题考察一般过去时与过去进行时的熟练转换。 Ⅱ. 用“when”与“while”完成句子。 (1) _____ Tom was eating supper, it began to rain outside. (2) Don't use your cell phone _____ you are driving a car. (3) What were you doing _____ Mr. Zhou came in? (4) Jim is good at math _____ Mary is good at English. (5) We were watching TV_____ the electricity was off. 对于以上题目，同学们只要掌握“when”与“while”引导的时间状语从句主从句所用的时态就可以了。对于其他的用法我们将到九年级去学。 Ⅲ. 单项选择 (1) I first met Lisa three years ago. She ___ at a radio shop at the time. A. has worked B. was working C. had been working D. had worked (2) My mother was reading while I ___ the music. A. listened to B. listened C. was listening to D. is listening to (3) I ___ my breakfast when the morning post came. A. had B. had been having C. have been having D. was having (4) When I arrived at his office, he ___ on the phone. A. was speaking B. spoke C. had been speaking D. had spoken 在以上题目中，（1）题考察在过去某一时刻发生的动作，即用过去进行时。（2）题考察while引导的时间状语从句两个动作同时发生，都用过去进行时。（3）（4）题考察when引导的时间状语从句，主句用过去进行时，从句用一般过去式。其他无须多考虑，从句，主句用过去进行时。 Ⅳ. 汉译英 (1) Lucy 和Lily昨天下午从3点到4点在游泳。 Lucy and Lily ______ ________ from 3:00 to 4:00 yesterday afternoon. (2) 当Mr Cook到家时，他正在听收音机。 When Mr Cook got home, his son ______ ______ to the radio (3) 当李雷在吃早饭时，吉姆进来了。 While Li Lei ______ ______________, Jim came in. 【错例探究】
