授课类型 听说课
授课文本
一、教材分析 Analysis of teaching material
What 本页是Unit5 Power of Ideas Section A的听说后续板块，围绕3D打印机这一发明展开，包含四项递进任务：1. 2a听力问答：听对话，回答两个问题，获取对话人物的活动、最喜欢的发明及其原因，抓取听力主旨信息。2. 2b语法填空：选用方框内read、design、produce、create、send动词，用正确形式补全句子，句子全部使用一般现在时被动语态，结合听力音频核对答案。3. 2c听力细节勾选：再听录音，勾选出3D打印机能够制作的物品，拓展了解3D打印的用途。4. 2d结对口语输出：列举日常使用物品，选出最实用的一项，和同伴对话交流它的外形与用途，实现语言迁移运用。课型属于听说课，核心语法：一般现在时被动语态；话题：发明及其用途；技能覆盖听、语法运用、口语表达。Why1. 主题层面：以3D打印现代发明为载体，让学生感受科技创新的力量，深化对“发明改变生活”单元主题的理解。2. 语言层面：2b依托听力语境练习被动语态，把语法学习融入听力材料，避免孤立讲语法；积累发明相关动词，夯实本单元重点语法。3. 技能层面：遵循“听主旨→语法内化→听细节→口语输出”的逻辑。从听力输入过渡到语法操练，再迁移到学生真实生活场景口语表达。4. 思维层面：引导学生思考身边发明的价值，学会评价发明的实用性，培养观察、归纳与交际表达能力，落实英语学科核心素养。
How实施路径 1. 2a主旨听力：学生浏览题干，听对话，捕捉人物经历与观点，完成两个问答题，把握对话大意。2. 2b语法操练：学生观察句子结构，判断被动语态，选用动词正确形式填空；播放录音核对答案，教师点拨 be + done 被动语态结构。3. 2c细节听力：再次播放音频，学生勾选3D打印机可制作的物品，同时鼓励学生补充更多现实生活中的打印产物。4. 2d口语输出：学生梳理自己日常用品，挑选最实用发明，借助对话模板结对问答，描述物品外观与用途，完成语言迁移输出。 语言特点 1. 语法：大量使用一般现在时被动语态（is + done），是本单元语法重点；方框动词均为和发明制作流程相关动词。2. 句式：听力对话为口语化短句；填空句为流程说明类陈述句；2d提供问答句式支架，降低口语输出难度。 文本结构特点 1. 任务链条层层递进：听力获取大意→语法聚焦操练→听力抓取细节→联系生活口语输出，由输入逐步走向输出。2. 语境化语法：语法不是单独讲解，嵌套在听力材料中，在发明流程语境中感知被动语态表意。3. 从陌生科技发明过渡到学生身边日常物品，由课本情境迁移至学生真实生活，降低表达门槛。
二、教学内容 Teaching content
1. 2a听力问答：听对话，获取人物活动、最喜欢的发明及其原因，完成问题作答，把握听力主旨信息。2. 2b语法填空：选用方框动词变形补全被动语态句子，结合听力音频核对答案，操练一般现在时被动语态。3. 2c细节听力：再次听录音，勾选3D打印机能够制作的物品，拓展了解这项发明的实际用途。4. 2d结对口语：列举日常用品，选出最实用的物品，依托对话支架和同伴交流其外形与用途，实现语言迁移输出。

In this class, I guided students to learn and talk about 3D printer and describe how it is used by listening, answering questions, watching videos and so on. In addition, we learned to get specific information about 3D printer through listening, including how it works.The most important thing we learned is that we should appreciate how 3D printing influences our daily life. However, the time is limited. It’s a pity that only two groups showed their conversations.In the next class, I will control the class time and give students more opportunities to show themselves.
