Unit 6 语法过去进行时 2025-2026学年外研版八年级上册

本讲义聚焦初中英语过去进行时核心知识点，以“结构-用法-辨析-应用”为学习支架，系统梳理基本结构（肯定句“主语+was/were+doing”、否定句及疑问句式），具体用法（过去某时刻/段时间动作、与频率副词连用表情感等特殊用法），并通过when/while引导从句的对比辨析深化理解，最终依托多样化习题实现知识巩固。 资料以情境化例句（如“You were always changing your mind”）和典型例题（如when/while辨析题）为载体，助力学生在理解与表达中提升语言能力，在对比分析when/while用法时培养思维品质，在分层习题（选择、句型转换等）中发展学习能力。课中辅助教师构建清晰知识脉络，课后学生可通过习题回顾与强化，有效弥补知识盲点，提升语法应用效率。

过去进行时 1. Alice was sitting by the river. 2. They were not cleaning the classroom at this time yesterday. 1、 过去进行时的基本结构 肯定句：主语+was/were+doing(现在分词) 否定句：__________________________________________ 一般疑问句及回答：________________________________ ______________ ____________ 特殊疑问句：______________________________________ 二、过去进行时的具体用法 1. 表示过去某个时刻正在进行的动作，常与then、at that time、at that moment、at this time yesterday、at nine last night等表示过去的时间状语连用。 I was watching TV then. What was she doing at nine o' clock yesterday evening? 2. 表示过去某一段时间内一直在进行的动作，常与those days、the whole morning、all day yesterday、"from+时间点+ to+时间点+ last night"等时间状语连用。有时要根据上下文语境判断。 He was learning swimming those days. We were jogging in the park from seven to eight last night. 例1 —I called you yesterday afternoon, but nobody answered. What were you doing? —I _______football the whole afternoon. A. play B. will play C. was playing D. am playing 3. 过去进行时的特殊用法： 过去进行时有时不单纯表示过去正在发生的事情，它还有其他用法: 1. 与频率副词 always, often, usually, all the time, constantly等连用，表示生气、厌恶、赞扬等感情色彩的情绪； e.g. You were always changing your mind. 你总是改变自己的想法。 2. 表示在过去即将发生的动作； e.g. She asked him whether he was coming back for dinner. 她问他是否回来吃饭。 3. 表示现在的想法，语气显得委婉； e.g. I was wondering if you could help me with this question.不知道你能否帮我回答一下这个问题。 例2 I called Hannah many times yesterday evening, but I couldn’t get through. Her brother__________(talk) on the phone all the time。 注意:一些动词不能用于过去进行时，比如agree,believe,love,mean,remember,understand 等。 三、when和while引导的从句与过去进行时连用辨析 1、when引导时间状语从句时，从句中的延续性动词用过去进行时，终止性动词用一般过去时。 2、“主句（过去进行时）+when引导的从句（一般过去时）”还可表示主句动作正在进行时，从句动作突然发生了，强调从句动作发生的突然性。 3、在while引导的时间状语从句中，动词必须是延续性动词。 4、当主句和从句的动作都是延续的或同时发生的，多用while引导。 It was raining when he reached school.当他到达学校时正在下雨。（reach为终止性动词） When we were having a party in the classroom, our head teacher came in.当我们正在教室举行聚会时，校长进来了。（have为延续性动词） We were talking when our teacher came in. 我们正在说话的时候，老师（突然）进来了。 I saw an accident while I was walking on the road.在路上行走时，我看见了一起事故。 We were dancing while they were singing.他们在唱歌，我们在跳舞。（dance和sing两个动作同时进行） 例3 When I saw Xiao Wang yesterday, he ______an old man cross the road.
