AI will make boring subjects more interesting—students will develop a stronger love for study.
Medical services will become more convenient. People won’t need to travel far for simple problems.
AI will develop smart traffic systems. Traffic jams will become less common, and we will save a lot of time on the way to school or work.
Daily life will be easier. AI robots will help with housework (like cleaning, cooking), so people will have more time to develop hobbies or stay with family.
...
AI will replace a lot of basic jobs. Many people will lose their jobs and find it hard to get new ones—this will create social problems.
Students will spend more time with AI than with teachers or classmates, so their communication skills will develop slowly.
People will become lazy and lonely. AI will do everything for us (like ordering food, chatting), so we will rarely go out or talk to others—face-to-face communication will become less common.
AI could be used for bad things. Some people may develop harmful AI (like fake news generators), which will influence people’s minds and cause social chaos.

授课题目 Unit 7 When Tomorrow Comes Section B (2a-2c) 课时 课型 第5课时 词汇课
主题情境 人与社会 — 科技发展与未来生活 授课教师
语篇研读 【What】 本节课语篇围绕 “人工智能主题下的词汇运用” 展开,涵盖三类核心词汇活动:基础匹配类:如 2a 的反义词匹配活动(more→less、possible→impossible 等),聚焦反义词的掌握与词汇关联建立;句子应用类:如 2b 的句子层面词汇填空,要求选用 accept、develop 等词汇的正确形式完成句子,强化词汇语法属性认知;语篇综合类:如 2c 的语篇填空练习,将词汇学习融入人工智能未来发展的小语篇中,既是对阅读板块访谈问题的答案补充,也是本单元主题意义的提炼。 【Why】 语篇的核心功能是 “词汇运用与主题深化”:通过分层递进的词汇活动,帮助学生巩固词汇知识、提升语境运用能力,同时依托 AI 主题语篇启发对科技伦理的思考,呼应 “为未来做好准备” 的单元核心,实现语言学习与思维发展的结合。 【How】 结构逻辑:遵循 “基础认知→句子应用→语篇综合” 层次,从反义词匹配到句子填空,再到语篇填空,难度逐步提升;语言特征:语篇多用将来时态(描述 AI 未来影响)、核心词汇(influence、challenge 等)和选择疑问句式(Will AI make our life better or worse ),衔接自然,适合八年级学生在语境中理解和运用词汇。
学情分析 八年级学生已具备以下基础与特点,需针对性设计教学: 语言基础:掌握基础词汇及简单反义词,能进行简单句子表达,但对反义词的构成规则(如否定前缀、合成词)理解不系统,在语境中灵活运用词汇正确形式(如名词复数、动词时态)的能力不足,语篇层面词汇整合运用较弱。 认知特点:对 “人工智能” 主题充满好奇,有一定的生活认知和兴趣,乐于参与辩论、小组合作等互动活动,但对科技伦理相关话题的深度思考和语言表达能力有限。 学习需求:需要系统梳理反义词构成规则,通过分层练习强化词汇语境运用能力,同时渴望在真实主题情境中拓展词汇运用场景,实现从 “记忆词汇” 到 “运用词汇表达观点” 的过渡。
课标要求 词汇学习要求 词义理解:能掌握反义词的不同构成方式(添加否定前缀、词形变化、合成词),准确理解核心词汇(accept、develop、influence 等)的词义及语义关联。 词汇运用:能在句子和语篇语境中正确使用词汇的适当形式,能结合 AI 主题拓展词汇网络,养成通过对比、分类积累词汇的习惯。 学习策略:能主动查阅词典积累反义词,能通过语境推测词汇正确形式,学会在主题语篇中整合运用词汇。 语篇学习要求 语篇理解:能识别语篇的 “观点 + 支撑” 结构,理解 AI 主题语篇中信息的逻辑关系,把握语篇对单元主题的提炼意义。 语篇创作:能依托主题和词汇储备,完成简单的观点表达语篇,能运用核心词汇和反义词组织语义连贯的内容。 3. 主题关联:能结合语篇思考 AI 对未来生活的影响,围绕科技伦理话题表达个人观点,实现语言学习与主题探究的融合。
教学目标 通过本节课学习,学生能够: 1.能够回顾已学词汇,观察并归纳反义词的不同构成方式,如添加前缀、词形变化或使用完全不同的词形。能够主动查阅词典,探索并积累更多反义词,拓展词汇量。能够养成通过对比、分类和自主查阅等高效学习词汇的习惯,增强独立积累和掌握词汇的能力。(学习理解) 2.能够结合语境灵活运用本单元所学新词汇(如accept、develop、influence、challenge等)进行表达。能够在句子(活动 2b)和语篇(活动 2c)层面准确选择和使用词汇的正确形式,强化词汇的语法属性认知,提升在真实语境中运用词汇的能力。(应用实践) 3.能够将词汇学习融入人工智能主题语境,理解词汇在主题中的运用,启发对科技伦理(如 AI 对生活的影响)的思考,为创造更美好的未来做好认知准备。能够运用所学词汇学习方法,在新的话题(如未来科技、生活变化)中独立拓展词汇积累,并用词汇进行表达和批判性思考。(迁移创新)
教学 重难点 重点: 掌握反义词的构成规则(添加否定前缀、词形变化、合成词),积累核心词汇(accept、develop、influence、challenge 等)的词义及用法。 能在句子和 AI 主题语篇中准确运用词汇的正确形式完成填空练习,强化词汇的语境适配能力。 难点: 灵活运用反义词构成规则自主拓展词汇,实现从规则记忆到实际运用的转化; 2. 在辩论或观点表达中,结合核心词汇和反义词,清晰、连贯地阐述对 AI 影响的观点,体现词汇的个性化运用和主题深度思考。
核心语言 【核心词汇】 基础词汇:more、less、possible、impossible、better、worse 等反义词对 核心动词:accept(接受)、develop(发展;培养)、influence(影响) 核心名词:challenge(挑战)、service(服务)、quality(质量) 其他词汇:traffic(交通)、creative(有创造性的)、nowhere(无处) 【核心短语】 词汇搭配:develop a plan(制定计划)、influence sci-fi writers(影响科幻作家)、public health system(公共卫生系统)、meet challenges(迎接挑战) 反义词组:more→less、possible→impossible、better→worse、everywhere→nowhere 【核心句型】 词汇运用句型:It is important for sb. to do sth.(对某人来说做某事很重要) 观点表达句型:AI will make our life better/worse.(人工智能会让我们的生活更好 / 更糟) 主题探究句型:Will AI change our world How (人工智能会改变我们的世界吗?如何改变?) 语篇呼应句型:It depends on how we choose to improve and use AI.(这取决于我们如何选择改进和使用人工智能)

板书设计
教学反思 本次词汇课聚焦 AI 主题,通过 “基础 - 句子 - 语篇 - 运用” 四层活动实现词汇学习与主题探究的融合,基本达成教学目标,但仍有优化空间。词汇教学中,部分学生对否定前缀的辨析(dis-、im-、un-)不够清晰,后续需设计针对性对比练习强化记忆;反义词拓展活动中,部分学生依赖词典,自主关联能力不足,可增加 “词汇联想接龙” 降低难度。语篇练习环节,学生对词汇形式变化(如 creative 的词性转换)易出错,需在讲解时增加词性标注和转换规则总结。课堂辩论中,部分学生词汇储备不足导致表达不流畅,可提前提供词汇支持卡片。作业反馈中,拓展作业的简笔画辅助环节落实不均,可在下次课设置展示环节激励学生。后续将通过分层练习、支架搭建、主题延伸等方式,进一步提升学生词汇运用的灵活性和主题表达的深度,落实课标要求。
