Unit 4 Amazing Plants and Animals Section A (1a-1d + Pronunciation) 教学设计（第一课时·听说课） 2026—2027学年　人教版（2024）英语八年级上册 课　　题 Amazing Plants and Animals（Unit 4 Section A 1a-1d + Pronunciation） 课　　型 听说课（Listening & Speaking） 课　　时 第1课时（45分钟） 授课年级 八年级上册 核心素养目标 素养维度 目标描述 语言能力 认读并掌握 moss, redwood, cheetah 等动植物词汇（课本 p.32）及其最高级形式（the largest / heaviest / fastest / most beautiful / oldest / tallest）；能听懂 Emma 与 Yaming 的“动植物之最”测试对话并完成排序、配对与表格；能用“What's amazing about…? —It's the…-est / the most…”问答；掌握 /eɪ/, /aɪ/, /ɔɪ/ 与辅音连缀 /bl/, /kl/, /gl/, /br/, /kr/, /gr/ 的发音，并体会句子重音改变语义的现象。 学习能力 听前依据 1a 图片与选项预测听力顺序；借助“最高级+名词”的搭配规律自主完成 1c 配对（Some have two answers）；通过同一句话三次重音朗读，自主归纳“重音位置不同、语义侧重不同”的规律。 思维品质 在“动植物之最”测试情境中将特征（最大、最重、最快、最美、最老、最高）与对应物种建立精确匹配；拓展思考 Which animal has the longest lifespan? 等新测试题，发展信息检索与归类能力。 文化意识 通过 Nature's amazing, let's keep it amazing! 的呼吁，认识到地球上神奇生命的珍贵，萌发热爱自然、保护动植物的态度。 教学重难点 教学重点：①1a 四种神奇动植物的特征描述与 1b-1c 听力任务（课本 p.32）；②形容词最高级“the+adj.-est / the most+adj.”与“one of the+最高级+名词复数”句型的初步运用；③双元音 /eɪ/, /aɪ/, /ɔɪ/、辅音连缀及句子重音（课本 p.33）。 教学难点：①听中快速捕捉最高级信息并完成“一物多配”；②重音改变语义的听辨与模仿（redwood / California / several 三种重读）；③多音节形容词最高级的准确朗读（the most beautiful）。 教学过程 教学环节 师生活动 活动观层次 评价要点 Step 1 Free talk 导入 (3’) ①Do you like animals and plants?
