We/You/They/ were working. 否定式：I/He/She/It was not working. We/You/They/ were not working. 疑问式和简略回答：Was I working? Yes, you were. No, you were not.Were you working? Yes, I was. No, I was not.Was he/she/it working? Yes, he/she/it was. No, he/she/it was not.Were we/you/they working? Yes, you/we/they were. No, you/we/they were not.注： was not常缩略为wasnt; were not常缩略为werent。探究二：过去进行时和一般过去时的区别：一般过去时：表示过去某个时间发生过的_或存在的_。如：I wrote a letter last night. (信写完了)过去进行时：过去_或_正在进行的_。如：I was writing a letter last night. (信不一定写完)探究三：过去进行时的用法：用法：1. 只有延续性动词才能用于过去进行时，短暂性动词不可以，它通常与when引导的时间状语从句连用，当一个动作发生时，另一个动作正在进行。如：I was cleaning the room when Tom called me.2. 过去进行时还可以表示两个过去的动作同时进行，这时可用while来连接两个从句。如：I was watching TV while my mother was cooking yesterday evening.when和while的区别：when和while都可表示“当的时候”，引导时间状语从句。你知道两者在过去进行时中的用法有什么不同吗？ 请仔细观察下面的例句，然后补全空格中的内容。 I was walking to school when I saw a cat in a tree. When Sally arrived home, her mother was cleaning the house. 主句的动作是持续性的，而从句动作是短暂性的，此时用_引导时间状语从句，主句用_时态，从句用一般过去时态。 While I was sleeping in the bedroom, someone knocked at the door. David fell while he was riding his bike. 主句的动作是短暂性的，从句的动作是持续性的，此时用_引导从句，主句用_时态，从句用过去进行时态。 While Andy was waiting for the bus, he was reading a newspaper. He was cleaning his car while I was cooking. 主句和从句的动作在过去的某时刻或某段时间同时发生，而且动作都是持续性的，此时用_引导从句，而且主句和从句都用_时态。(1) 表示“当的时候”时，如果后面连接的动词为延续性动词，则多用while，而when通常与短暂性动词连用（也可与延续性动词连用）；当后面的句子表示一种状态时，两者可以互换。 如：While I was buying a newspaper, my dog ran away. =I was buying a newspaper when my dog ran away. I was very short when/while I was in primary school.(2) 如果while前后的句子都是进行时态（现在进行时或过去进行时），while可译为“与此同时”。如：I was sleeping while my mother was cooking breakfast.(3) 当while前后的句子描述的情况相对或相反时，while可译为“而”，while更强调并列的对比而非转折。如: I like Chinese food while she likes French food.(4) 当when引导的带有短暂性动词的从句与进行时态的主句连用时，when 有时候可以根据情况译为“突然，就在这时”。如：I was sleeping when the door opened.【课堂检测】I. 用when 或while填空1. _Tom was eating supper, it began to rain outside.2. Dont use your cell phone _ you are driving a car.3. What were you doing _Mr. Zhang came in?4. Jim is good at math _Mary is good at English.5.
