Unit 8 Grammar 学案2025-2026学年沪教版七年级英语下册

该初中英语导学案围绕时间状语从句（when/as/after/before）和used to结构展开，以“时光记录官”项目导入，通过Peter Goldman和Liu Wei的案例引导观察，设置自我发现问题梳理语法规则，搭配专项训练支架（选词填空、句型重组等），连接探究与应用。 特色在于项目式驱动与语法探究结合，任务链从解密（观察归纳）到对比（结构分析）再到产出（写作胶囊说明书），写作脚手架提供句型支持提升语言能力，通过自主探究培养思维品质，习题贴合中考题型助力学习能力提升。

Unit 8 Follow your interests 项目式语法探究学案（同课异构） 班级：_________________ 姓名：_________________ 学号：_________________ 📋 项目背景与驱动问题 (Project Background & Driving Question) 每个人的成长都伴随着兴趣爱好的改变。你过去喜欢什么？现在又在坚持什么？本期项目我们将化身为“时光记录官”，设计一个【个人兴趣时光胶囊 (My Interest Time Capsule)】。通过回顾过去、记录现在、规划未来，展现我们真实的成长轨迹。 💡 核心驱动问题：我们如何用英语准确地向朋友介绍自己爱好的“时间进化史”以及我们在爱好中投入的时间规划？ 📂 任务一：时光解密 —— 探究时间状语从句的“先后密码” 作为时光记录官，在整理 Peter Goldman 的人生经历（课本 P121）时，我们发现了以下几个关键的“时间节点”。请仔细观察这些句子中加粗的连词，完成下方的探究。 ① I started school when I was six. ② As I got older, I started thinking about how to turn this into a career. ③ After I graduated, I got my dream job with a Formula 1 racing team! ④ Before each race started, my job was to check all the cars and fix any problems. 🕵️‍♂️ 探究有道 1：自我发现 1. 翻译连词：尝试结合上下文，写出下列连词在句子中的中文含义： - when / as：__________________ - after：__________________ - before：__________________ 2. 位置观察：观察例句②③④，当连词引导的句子放在句首时，主从句之间有什么标点符号？___________；再观察例句①，当连词引导的句子放在句尾时，还需要这个标点符号吗？___________。 3. 脚手架归纳：像这样由连词引导、用来表达动作发生时间的句子，叫做时间状语从句。通过观察我们可以得出： - 表达两件事“同时发生”或“随着发生”常用连词：_____________ 或 _____________ - 表达事情的“先后顺序”，即“在……之后”用 _____________，“在……之前”用 _____________。 🏋️‍♂️ 脚手架训练营 1：基础夯实操练（连词专项突破） 👉 训练A：选词填空（根据句意，从 when, before, after, as 中选择最合适的词填空，每词可重复使用）。 1. Brush your teeth ____________ you go to bed. It's good for your health. 2. ____________ the teacher came into the classroom, all the students stopped talking. 3. I always finish my homework ____________ I play video games. 4. ____________ the music played, the children started to dance happily. 5. Please turn off the lights ____________ you leave the room. 6. My father arrived home ____________ I was eating dinner. We smiled at each other. 7. We can go out to play football ____________ the heavy rain stops. 8. Think carefully ____________ you answer the teacher's questions. 9. ____________ I grew up, I became more interested in playing the piano. 10. My mother usually reads a book ____________ she goes to sleep. 👉 训练B：句型重组（用括号内的连词将两个独立的句子合并为一个含有时间状语从句的句子，注意标点）。 1. I finished my primary school. I came to this junior high school. (after) _________________________________________________________________________ 2. You cross the busy street. You must look both ways first. (before) _________________________________________________________________________ 3. I was very young. I liked playing with toy cars. (when) _________________________________________________________________________ 📂 任务二：时光对比 —— 探究 used to 的“变身特技” 在“时光胶囊”中，我们需要对比自己的过去与现在。请观察教材 P122 给出关于 Liu Wei 的生活对比，并体会语法规则。 • 肯定对比： 过去：Liu Wei used to go to school on foot. (刘伟过去常常步行上学。) 现在：Now he goes to school by bike. • 否定对比（根据图1提示）： 过去：He didn't use to enjoy swimming. (他过去不喜欢游泳。) 现在：Now he goes swimming every week. 🕵️‍♂️ 探究有道 2：结构归纳 1. 语义发现：`used to + 动词原形` 表示过去_________________ 做某事，而现在_________________（做/不做）。 2. 否定微探究：观察否定句中，`didn't` 后面使用的是 `used to` 还是 `use to`？_________________。这是因为助动词 didn't 后面必须要恢复成_________________。 🏋️‍♂️ 脚手架训练营 2：核心能力操练（used to专项突破） 👉 训练C：单项选择突破（针对中考基础题型精选） 1. My sister ______ like vegetables, but now she loves carrots and tomatoes very much. A. use to B. used to C. didn't use to D. didn't used to 2. There ______ be a big tree in front of our house, but it was cut down last month. A. used to B. use to C. used to are D. is used to 3. — Did your brother use to play the guitar? — No, he didn't.

A. didn't use to B. used to C. use to D. uses to 5. Peter ______ get up early, so he was often late for school last term. A. used to B. didn't use to C. didn't used to D. use to 👉 训练D：句型转换（每空一词，确保形式准确）。 1. I used to fly kites when I was a child. (改为否定句) I ________ ________ ________ fly kites when I was a child. 2. My uncle used to be a football player. (改为一般疑问句) ________ your uncle ________ ________ be a football player? 3. Linda often went to bed late in the past. (用 used to 改写同义句) Linda ________ ________ ________ to bed late in the past. 📂 任务三：时光产出 —— 制作你的“兴趣时光胶囊”说明书 请结合本节课学到的时间状语从句和 `used to` 结构，为你的“兴趣时光胶囊”写一份英文介绍，对比自己某项兴趣爱好的变化。 🛠️ 写作脚手架 (Writing Scaffold) 你可以选用以下句型结构来丰富你的写作： 1. I used to like... when I was in primary school. 2. I didn't use to play/do..., but now it is my favorite hobby. 3. Before I start practicing every day, I always... 4.
