01 Unit 12 第1课时 Section A(1a-2d)（同步学练测）-【全效学习】2025-2026学年九年级英语全一册同步学练测课件PPT（人教版）

该初中英语九年级全册第1课时课件，核心涵盖词汇构词（如unexpected的un-否定前缀、oversleep的合成词构成）、语法（by the time的三种时态用法）及短语（go off, keep doing sth.等）。课堂导学时先解析词汇构词规律，再以典型例句为支架分情况讲解语法，构建词汇到语法的连贯知识脉络。 其亮点在于融合语言能力与思维品质培养，如微语篇练词汇结合语境巩固单词运用，语法部分通过时态对比（过去完成时与一般过去时等）引导学生分析逻辑关系。练习设计分层（单词填空、汉译英、语篇应用），助力学生提升语言理解与表达能力，教师可直接用于课堂检测，有效提高教学效率。

第1课时 英语九年级全册 01 课堂导学 02 基础达标 CONTENTS 目 录 01 课堂导学 1．unexpected adj.出乎意料的；始料不及的。是由形容词expected(预料的)加否定前缀un­构成的。 2．backpack n．背包；旅行包 3．oversleep v．睡过头；睡得太久。合成词，由over(超过)＋sleep(睡觉)构成，其过去式和过去分词均为overslept。 4．by the time… 在……以前。by the time的时态选择分以下三种情况。 第1课时 返回目录 (1)如果从句中的谓语动词是一般过去时，那么主句中的谓语动词通常用过去完成时，表示“截止到从句动作发生时，主句动作已经完成，即过去的过去”。 【典型例句】By the time he got home, I had finished cooking dinner. 当他回到家的时候，我已经做好晚餐了。 第1课时 返回目录 (2)如果从句中的谓语动词为一般现在时或现在完成时(表示将来)，那么主句中的谓语动词常为将来完成时，表示“截止到将来某一时间为止，主句动作将已经完成”。 【典型例句】By the time you arrive, the concert will have ended. 到你到达的时候，音乐会将已经结束了。 第1课时 返回目录 (3)如果主句动作不强调已经完成，只是说明某个时候的状况(主句是be的系表形式或者是像know, find, believe等表示认知的持续性动词，则往往用一般时态，不用完成时态)，此时主句不用完成时，而应根据实际需要选用适当的时态，此时by the time相当于when。 【典型例句】 By the time we got home, we were tired and hungry. 回到家的时候，我们已经又累又饿了。 第1课时 返回目录 5．go off 响起；发出声音；叫响。相当于动词ring。 6．keep doing sth. 一直做某事；继续做某事 【拓展】keep doing sth. 表示不断地做某事(不间断)，其后可接延续性动词。 【典型例句】They kept watching the beautiful view out of the window. 他们一直观看着窗外的美景。 7．give sb. a lift 捎某人一程。书面用语。与give sb. a ride意思相同，但后者常用于口语中。 第1课时 返回目录 02 基础达标 一、用括号内所给单词的适当形式填空 1．Spring is coming.
