内容正文:
Unit 4 I used to be afraid of the dark Section A(1a -2d)教学设计
一、教材分析
本课时选自人教版九年级 Unit 4 Section A,是单元开篇内容。以“谈论人物过去与现在的变化”为主题,通过 1a(外貌与性格词汇分类)、1b - 1c(朋友重逢的听力与对话)、2a - 2c(Paula 变化的听力与图表填空)、2d(对话角色扮演),层层渗透“used to do/be”结构。教材以“朋友互动”为真实情境,既贴近学生生活,又为后续阅读、写作奠定语言与话题基础。
二、学情分析
1. 知识基础:学生已掌握“tall, outgoing”等描述外貌、性格的词汇,熟悉一般过去时,但对“used to”(表达过去习惯性状态/动作)的结构较陌生,易与一般过去时混淆。
2. 能力水平:具备基本听说能力,但在复杂语境中连贯运用“used to”表达的能力不足,部分学生口语表达较胆怯。
3. 学习特点:对“朋友/自身变化”话题兴趣浓厚,偏好互动性听说活动,需直观示例与充分练习掌握新结构。
三、课时目标
(一)语言能力
1. 能准确用“used to + do/be”结构描述人物外貌、性格、兴趣的过去与现在变化(如 Mario used to be short. Now he’s tall.)。
2. 能听懂关于人物变化的对话,提取关键信息(如 1b、2b 听力任务)。
3. 能运用目标结构创编对话(1c、2c)并进行角色扮演(2d)。
(二)文化意识
理解“成长中变化是正常现象”,学会用发展的眼光看待自己与他人。
(三)思维品质
通过“过去-现在”对比,培养逻辑思维;通过对话创编,提升创造性思维。
(四)学习能力
能在小组合作中互助学习,借助听力材料与同伴交流解决语言疑问。
四、评价任务
1. 词汇与结构掌握:通过 1a 图表填写、1b 听力填空,评价“used to”及描述性词汇的掌握度。
2. 听力理解:通过 1b、2b 的听力任务完成情况,评价获取关键信息的能
力。
3. 口语表达:通过 1c、2c 的对话创编和 2d 的角色扮演,评价“used to”结构的运用流畅度与准确性。
4. 情感参与:观察小组合作的参与度与对话练习的积极性。
五、学习活动设计(45 分钟)
(一)导入:激活旧知,引入主题(5 分钟)
1. 展示对比照片,提问:“Who is this? What did he/she use to look like?
What’s he/she like now?” 学生自由回答。
2. 引出课题:“Today we’ll learn to talk about what people used to be like and how they’ve changed. Let’s start with Unit 4 I used to be afraid of the dark.”
(二)新知呈现:1a - 1c,学习“used to”描述外貌/性格变化(15 分钟)
1. 1a:分类词汇,夯实基础
呈现 1a 的 Appearance(外貌)”与“Personality(性格)”,引导学生补充更多词汇(如 Appearance:short, curly hair, thin...;Personality:quiet, serious, humorous...),教师板书。
互动游戏“词汇分类抢答”:教师说词汇,学生快速判断属于“Appearance” 还是“Personality”,巩固词汇分类。
2. 1b:听力输入,提取信息
听前:展示 1b 问题(“What did Bob’s friends use to look like?”),明确任务。
听中:播放录音,学生完成填空(如 Mario used to be short; wore glasses...)。
1. Mario used to be _____. He used to wear ______.
2. Amy used to be ____. She used to have ______hair.
3. Tina used to have ____ and ______ hair.
答案short glasses tall short red curly
听后:核对答案,邀请学生分享听力成果。
3. 1c:对话创编,初步运用
示范:教师与一名学生用 1c 示例对话(A: Did Mario use to be short? B: Yes, he did. He used to be really short. A: What’s he like now? B: He’s tall now.)。
小组活动:4 人一组,根据 1a 图片和 1b 内容,创编关于 Mario、Amy、Tina
的对话,教师巡视指导。
班级展示:邀请 2 组学生表演对话,教师点评(重点关注“used to”的正确使用)。
(三)能力提升:2a - 2d,拓展“used to”至兴趣/习惯变化(20 分钟)
1. 2a:听力预热,熟悉词汇
呈现 2a 的词汇(friendly, outgoing, serious...),学生快速认读并标记认识的词汇。
播放录音,学生勾选听到的词汇,随后核对答案。
2. 2b:细节听力,梳理变化
听前:展示 2b 的“In the past”与“Now”对比表格,明确任务(“How has Paula changed?”)。
