摘要:

该初中英语课件聚焦构词法(后缀-en)与被动语态(一般现在时、一般过去时),通过“历史发明档案馆”情境导入,结合三张图片英文线索引导学生观察加粗词汇发现构词规律,再过渡到对话探究被动语态结构,搭建从构词到语法的学习支架。 其亮点在于融合语言能力、思维品质与文化意识培养。通过“反诈预警”辨析被动语态易错点,2026年真题演练强化时态判断,微写作任务结合发明史提升表达能力。采用情境任务驱动教学,以“核心法宝”总结规律,帮助学生提升语法运用与逻辑思维,为教师提供结构化、生活化的教学资源。

内容正文:

Unit 3 Great Ideas Grammar in Use: 构词法与被动语态 主讲人:XXX 课型:语法课 能够从对话和语篇中提取被动语态的核心结构,并分析 动作的执行者与承受者。(应用实践) 02 能够用被动语态描述生活中的常见发明,并完成相关语篇填空。(迁移创新) 03 掌握后缀 -en 的构词规律,能正确区分并运用一般现在时和一般过去时的被动语态;了解古代建筑、经典电器及便利贴的发明史,感悟人类在科技探索中的智慧。(学习理解) 01 学习目标 Contents Lead in 01 Presentation 02 Practice Discovery 03 Application 04 & Summary 05 Language points 06 Exercises 07 Homework 08 01 Lead in 跨越时间的故事 In the old days, stone was difficult to transport, so many wooden houses were built. Television can enrich people's lives and broaden their minds. Around 2000 BCE, woolen clothing appeared in China. 案情提示: Lead in 时空调查员们,欢迎来到“历史发明档案馆”!今天的第一个任务是破译“时空密码”。这三张来自不同世纪的现场照片,隐藏着三条关键的英文线索。请大声朗读它们,并特别关注句子中加粗的词汇: 这些加粗的单词,就像会变形的特工。它们是从哪里“进化”而来的?让我们一起解构这个构词魔法! 02 Presentation 后缀 -en 的“变形魔法” 请查阅档案,用构词公式破解教材 Activity 2 的4道填空题。 规律总结 名词/形容词 + -en → 形容词 表示“由……制成的” 例:wood → wooden 木制的 原词(暖橙加粗) 音标(黑色) 词性 对应新词/填空 wood /wʊd/ n. wooden (adj. 木制的) short /ʃɔ:t/ adj. shorten (v. 缩短) wide /waɪd/ adj. widen (v. 拓宽) dark /dɑ:k/ adj. darken (v. 变暗) 教材 Activity 2 验证: Chinese people used wooden (wood) boards to print books. Movable type printing could greatly shorten (short) the printing time. You need to widen (wide) your knowledge. When sky began to darken (dark), sailors had to depend on stars. 形容词 + -en → 动词 表示“使……变得” 例:short → shorten 缩短 Presentation 密码破译行动开始!我们刚才发现的加粗词汇,都是由“名词/形容词 + 后缀 -en”进化而来的。有的是变成形容词(表示“由什么材料制成”),有的进化为动词(表示“使某物变成什么样”) 03 Practice & Discovery 03 Practice & Discovery 探究被动语态的秘密 构词法过关了!现在请打开教材第2页 Activity 1,同桌互相朗读 Kangkang 和老师的对话,圈出所有的动词,并完成下面的探究任务。 老师: Hi, Kangkang, why do you look so tired? Kangkang: I was woken up by my mom too early this morning. 老师: You stayed up late last night, right? Kangkang: Yes, I did. I made a model rocket last night. It was made for the model rocket show this Sunday. 找一找: 对话里含有“be动词 + 过去分词”的结构是哪两句? (答案: was woken up, was made) 想一想: Kangkang 是“主动”叫醒妈妈,还是“被”妈妈叫醒的? 火箭是“自己”做的,还是“被”做的? 知识铺垫: 当主语是动作的承受者时,我们就要用到被动语态。 04 Application 04 Application 恭喜你破案!现在,我们要为一份被遗忘的“伟大发明档案”补充关键信息。 请将刚才发现的被动语态法则(公式)填进去,完成教材 Activity 2 和 Activity 3 取证法则:主语 + be (am/is/are/was/were) + 动词过去分词 教材 Activity 2 表格归纳: 时态 主动语态 被动语态结构 一般现在时 do / does am / is / are + done 一般过去时 did was / were + done Activity 2 填空核对: The passport was discovered (discover) in the Lost and Found. Many art works are created (create) by young people today. The airplane was invented (invent) by the Wright brothers in 1903. Potato chips were invented (invent) by George Crum in 1853. Activity 3 语篇实战(便利贴的诞生): Post-it notes ( were invented ) in 1968 by Dr. Spencer Silver. In 1974, Art Fry found a good use of them. While people were singing, the notes ( were used ) to keep pages from falling out. Now, notes ( are used ) all over the world. 05 Language points Language points 05 掌握了 -en 的规律后,我们回到教材第1页的 Activity 3, 用构词法替换划线部分,把句子写得更地道。 题目1 原文: I like this invention. Pencils can be made sharp by using a small tool. 替换: Pencils can be sharpened by using a small tool. (sharp + en 变成动词,意为“使变锋利”) 题目2 原文: I like the invention of light bulb. It makes the world around us bright at night. 替换: The light bulb is an important invention. It brightens the world around us at night. (bright + en 变成动词,意为“使变明亮”) [1] [2] [3] [1] focntis expnli, 100 (007m) "##o.04" 05 Language points 调查员请注意!被动语态中有几个“高发骗局(易错点)”,请大家擦亮眼睛, 反诈预警① 千万不能漏掉 be 动词 (am/is/are/was/were)。 反诈预警② 不动词必须变形为 过去分词(done) 不能用原型 易反诈预警③ 区别“谁做”用 by “用什么”用 with 反诈实战演练 (2026年最新背景) The new campus library (build) by the workers last year. Many beautiful kites (make) by the students in our art club every spring. This ancient wooden bridge (repair) by the local people in 2025. The science books (keep) in the school library right now. 核对答案 was built; 2. are made; 3. was repaired; 4. are kept. 牢记反诈要点!。 06 Summary 06 Summary 构词法: 被动语态公式: 经过今天的学习, adj./n. + -en 主语 + be →动词/adj. 我们掌握了两项 (am/is/are/was/were) (wood→wooden; + 过去分词 “核心法宝”: short→shorten; sharp→sharpen) 3 时态区分: 一般现在时 (am/is/are done) VS. 一般过去时 (was/were done) 语篇理解与迁移写作 阅读判断(根据教材Activity 3便利贴短文判断正误 T/F): Dr. Spencer Silver invented post-it notes in 1974. Art Fry found a good use of the notes while he was singing. ( T ) Post-it notes became popular only in Boise, Idaho. ( F ) 微写作任务: 请结合课文“便利贴是被发明出来的”这个故事, 用被动语态写一段约50词的短文,介绍一个你身边的发明 (比如:自行车、钢笔、校服等)。 It was invented in + 年份 / 地点… 写作 框架 It is used for + 目的… It is made of + 材料… It is used by + 人群… 07 Exercises ( F ) 1 2 3 4 07 Exercises Exercises 07 真题演练(2026年名校最新题) 最终大闯关来了,这四道2026年最新中考被动语态真题,专门检验你们的“时间预判”能力, 请根据句子里的时间状语,快速锁定时态! 1. The 2026 Summer Science Camp by the school last week. will hold holds was held is held 2 2. Many new energy cars in our country every year. produce produced were produced are produced 3. The old town walls (repair) by the government in 2025. ( repaired were repaired are repaired repair It in most bookstores now. sells was sold is sold sold 核对答案:1.C(last week); 2. D(every year); 3.B(in 2025); 4.C(now) 4. -Where can I buy this book? 同学们,最后的思维拓展:英语中,我们习惯用被动语态 (be done) 来描述发明和客观事实,体现了西方文化对 “动作结果”和“客观事实”的强调。 而在汉语中,我们更习惯用“以人为主语”的主动句 (如:中国人发明了造纸术,而不是“造纸术被中国人发明” ))。掌握这种思维的差异,能让我们在以后的英语写作中 自然地想到用被动语态,使表达更地道、更客观。 Exercises 综合拓展(文化差异) 08 Homework 08 Homework 基础关(必做) 熟读教材第2页的对话(Kangkang and teacher), 并能和同桌流利地分角色表演出来; 完成本课配套基础题。 提升关(选做) 完成上一页(第19页)的微写作小短文, 要求使用至少3个被动语态句子。 08 Homework 拓展关(挑战,2026年科技背景) 查找一项2026年新发明的科技产品(例如最新能源汽车、 AI教学辅助等),用英语写3句话介绍它,其中必须包含 被动语态(如:It was invented by… / It is used for…)。 下节课预告 我们将继续探索科技的奇妙世界,下一站, 我们将聊聊更多现代发明。 Reflection & Action 知识回顾:今天我们从词语的变形(-en)学到了 语言的“创造力”,从被动语态(be done)学会了 如何客观描述发明的“被创造”过程。 全球视野链接:不管是便利贴、电视机还是木屋, 每一件伟大的事物都不是凭空出现的,而是被创造 出来的。我们每一个人,都可以成为未来的创造者! 梦想从学习开始,创造因你而改变世界! 感谢观看 Thank you for your participation! $
