Grammar 过去进行时 一般来说，要表示过去某个时刻或某一时段正在进行的动作，我们常使用过去进行时。常和过去进行时连用的时间状语有：then, at this/that time, yesterday, at... last night等。 - What were you doing at 7 am yesterday? 昨天早上7点你在做什么？ - I was having breakfast. 我在吃早餐。 过去进行时 过去进行时除了表示"过去某时刻/时段在做某事"之外，还常常出现在讲故事的语境中，请看下面的句子： Alice was sitting with her sister by the river. 艾丽斯正和姐姐坐在河边。 They were having a tea party in the garden. 他们正在花园里举行茶会。 过去进行时 过去进行时句子中的谓语部分由"was/were+动词现在分词"构成，与现在进行时结构相似，只是现在进行时中的am/is/are变成了was/were。由此可以推断，过去进行时的句式变化也与现在进行时的一样。过去进行时的结构分为：肯定句、否定句、一般疑问句和特殊疑问句。 过去进行时 过去进行时的结构 肯定句：主语 + was/were + 现在分词（-ing）+ 其他. She was singing when I entered the room. 我进房间时，她正在唱歌。 They were arguing about the movie last night. 昨晚他们一直在争论那部电影。 过去进行时 过去进行时的结构 否定句：主语 + was/were + not + 现在分词（-ing）+ 其他. He wasn't paying attention during the meeting. 开会时他根本没在听。 We weren't joking—this is serious! 我们没开玩笑，这是认真的！ 过去进行时 过去进行时的结构 一般疑问句：Was/Were + 主语 + 现在分词（-ing）+ 其他? Were you still doing your homework when I called you last night? 昨晚我给你打电话时，你还在写作业吗？ Was the baby crying loudly when the earthquake started? 地震开始时，婴儿正在大哭吗？ 过去进行时 过去进行时的结构 特殊疑问句：疑问词（What/Where/Why等） + was/were + 主语 + 现在分词（-ing）? What were you doing at 10 AM yesterday? 昨天上午10点你在干什么？ Why was she crying in the hallway? 她为什么在走廊里哭？ 过去进行时 过去进行时和一般过去时虽然都表示过去发生的事情，但是过去进行时强调过去某一时刻或时段正在进行或持续的动作；一般过去时表示过去的时间里所发生的动作，所表示的动作往往已经完成。 Laura was reading a novel at eight o'clock last night. 昨晚8点Laura在看小说。 Laura read a novel last night. 昨晚Laura看了一本小说。 过去进行时 过去进行时常和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引导的表示过去的时间状语从句连用，形成复合句。 One day, when Henry was working in a restaurant, a snake suddenly appeared. 一天，当Henry正在餐馆里工作时，一条蛇突然钻了出来。 过去进行时 过去进行时还可以和when, while, as引导的表示过去的时间状语从句连用，形成复合句。 While people were waiting for the traffic lights, a car suddenly appeared round the corner. 就在人们等待红绿灯的时候，一辆汽车突然从拐角处驶出。 As the doctors were checking him, the pain got worse. 医生给他做检查时，疼痛加剧了。 过去进行时 when和while引导的从句与过去进行时连用的几种情况： when引导的时间状语既可以指时间点，也可以指时间段，动词可以是终止性动词，也可以是延续性动词；while引导的时间状语只指时间段，动词必须是延续性动词。 They arrived while we were having dinner. 我们吃饭时他们到了。 = They arrived when we were having dinner. 过去进行时 when和while引导的从句与过去进行时连用的几种情况： 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。 We were talking when the teacher came in. 我们正在讲话，老师(突然)进来了。 过去进行时 when和while引导的从句与过去进行时连用的几种情况： 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) 过去进行时 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。 They were singing while we were dancing. 他们在唱歌，我们在跳舞。 While I was cooking, my brother was setting the table. 我在做饭时，我弟弟在摆餐具。 Homework Review the key words, expressions and sentence patterns in today's lesson.
