授课题目 Unit 4 Amazing Plants and Animals Section A(Grammar) 课时 课型 第3课时 语法课
主题情境 人与自然 — 动植物特征描述 授课教师
语篇研读 【what】 本课时语篇为教材中 “Grammar Focus” 板块的 3a、3b、3c 内容,聚焦形容词和副词最高级的语法知识。其中:3a 通过包含最高级的句子(如 “The blue whale is the largest...”“I think the most useful plant in the world is bamboo”),引导学生观察并总结最高级的构成方式;3b 要求用括号内单词的最高级形式完成句子,涉及动物(熊猫)、植物(玫瑰、牡丹)等主题;3c 需用方框内单词的最高级(ancient, beautiful 等)补全关于银杏树的短文,体现最高级在语篇中的应用。整体内容围绕 “动植物特征描述” 展开,将语法规则融入具体语境,形成 “感知 - 练习 - 应用” 的逻辑链,其中竹子相关表述为核心案例。 【why】 从课程标准角度,旨在让学生掌握形容词和副词最高级的构成规则(规则变化与不规则变化),能在语境中正确运用最高级描述事物特征;通过竹子等植物主题的语篇,培养学生对自然的关注,同时提升语法知识的实际运用能力,为描述身边事物或跨文化交流中的比较表达奠定基础。 【how】 内容特征:以 “人与自然” 为主题,将抽象语法规则与竹子等具体动植物情境结合,贴近学生生活经验,降低理解难度; 教材结构:从单句观察、单句填空再到语篇补全,层层递进,符合 “感知规则 - 机械练习 - 灵活应用” 的语法学习规律; 语言特点:句子简洁明了,语境指向性强,如 “the most useful plant”“the fastest-growing plant”,便于学生聚焦最高级的形式和用法,如 “the + 最高级 + 范围” 结构。
学情分析 【已有基础】 八年级学生在前两课时已学习描述动植物特征的形容词及最高级用法,掌握简单的问答句型,具备一定的最高级特征辨识能力。对 “人与自然” 主题有初步认知,且在日常生活中对竹子有一定了解,为学习本课时内容奠定了基础。 【发展需求】 学生希望能系统掌握最高级的构成规则,避免拼写错误,并能在描述竹子等植物或生活场景时灵活运用,提升语言表达的准确性。 【存在问题及拟解决措施】 存在问题:对多音节词最高级加 “most”与单音节词最高级加 “-est”的区分不清晰;不规则变化,如 “good-best”“bad-worst”易混淆;忽略 “the” 的使用,如漏说 “the tallest”。 拟解决措施:通过对比表格梳理规则与不规则变化;设计 “找错误” 游戏强化 “the” 的使用;结合竹子图片情境,引导学生在表达中巩固规则。
课标要求 能掌握形容词和副词最高级的构成形式——规则变化与不规则变化; 能在语境中正确运用最高级描述人或事物的特征,理解 “the + 最高级 + 范围” 的结构; 能读懂包含最高级的简单语篇如短文、句子,完成填空、补全信息等任务; 能运用最高级进行简单的口头或书面表达,描述身边的事物。
教学目标 通过本节课学习,学生能够: 能识别并总结形容词和副词最高级的构成规则(单音节词加 “-est”,多音节词加 “most”;不规则变化如 good-best 等);能准确说出 “the + 最高级 + 范围” 的基本结构及 “A is one of the + 最高级 + 名词复数 + 范围” 句型。(学习理解) 能完成单句填空和语篇补全任务,正确率不低于 80%;能通过趣味活动运用最高级描述竹子的特征,如生长速度、用途等。(应用实践) 能结合生活实际,用最高级描述身边的事物(如植物、动物、学习用品等),并与同伴交流,提升语法知识的实际运用能力。(迁移创新)
教学 重难点 重点:掌握形容词和副词最高级的构成规则(规则与不规则变化);正确运用 “the + 最高级 + 范围”“A is one of the + 最高级 + 名词复数 + 范围” 结构描述事物。 难点:区分多音节词与单音节词的最高级构成;在语篇和活动中灵活运用不规则变化的最高级(如 “the most ancient”“the best”)。
核心语言 【核心词汇】 形容词 / 副词(原级及最高级): cute→cutest;beautiful→most beautiful;colourful→most colourful;high→highest;large→largest;heavy→heaviest;ancient→most ancient;good→best;popular→most popular;fast→fastest;useful→most useful 范围状语: in the world;among all animals;across China;among plants 【核心句式】 主语 + be + the + 最高级 + 范围状语 例:Bamboo is the fastest-growing plant in the world. 主语 + 动词 + the + 最高级 + 范围状语 例:The cheetah runs the fastest among all land animals. 主语 + be + one of the + 最高级 + 名词复数 + 范围状语 例:Bamboo is one of the most useful plants in China.

教学过程
教学环节 教学活动 学生活动 设计意图
Part1: Lead in (3min) Show pictures: pictures of bamboo, giant pandas, African elephants, and cheetahs. Ask: "Which plant do you think is the most useful " "Which animal runs the fastest " Guide students to answer with "the most..." and introduce the concept of "superlatives": "Today we’ll learn how to learn about superlatives, especially about bamboo." 观察图片,用中文或简单英语回答问题,初步感知 “最高级” 的含义,聚焦竹子主题。 通过直观图片激活学生对 “最……” 的认知,结合竹子主题自然引出本节课,降低语法学习的抽象感。
效果评价:师评。观察学生能否结合图片说出 “最有用”“最快” 等概念,判断其对最高级的前期认知。
Part 2: Presentation(10min) T present the sentences from 3a. Read the sentences and notice the words in bold, What are the ways to form a superlative adjective or adverb Ask:"How do we form these words What’s the rule " T organize group discussions for 5 minutes, with the teacher circulating to provide guidance. Ss share their findings. The teacher summarizes and writes the rules on the blackboard. 小组讨论 3a 句子,尝试总结最高级构成规则; 记录教师板书的规则,标注易错点。 通过 “自主观察 - 合作总结 - 教师梳理” 的流程,让学生主动感知规则,结合竹子例子加深理解。
效果评价:组评 + 师评。检查小组总结的规则是否完整,关注学生对 “多音节词加 most” 及竹子相关句型的理解。
Part 3: Practice(15min) T ask Ss to finish 3b: Complete the sentences with the superlative forms of the words in brackets. T lead Ss to summarize the common mistakes when completing the sentences. Activity 1: Error Detectives shows sentences with mistakes.Students act as "detectives", circle the mistakes with red pens, correct them, and check each other's work in groups. 独立完成 3b,小组核对答案,总结常见易错点 参与 “纠错小侦探” 活动,找出错误并改正,小组内分享。 通过机械练习和趣味纠错活动,巩固规则,强化对易错点的记忆,结合例子有针对性提升。
效果评价:自评 + 师评。教师观察学生在 3b 练习中独立完成时对 "the" 的使用、拼写及最高级形式转换的准确性,关注不同水平学生的完成情况;在活动1中,观察学生能否快速识别典型错误,关注小组内是否通过讨论达成纠错共识。对表现好的学生给予鼓励,对共性问题集中讲解,综合评估学生对基础规则的掌握程度和对细节规则的理解深度。
Part 4: Application(15min) T lead Ss to finish the task in 3c: Complete the passage with the superlative forms of the words in the box. Activity 2: Bamboo Characteristics PK Contest T shows 3 characteristic cards of bamboo: growth speed, usefulness, distribution range. Ss draw cards and describe the characteristic with the superlative form, stating the scope. Other groups judge if it's correct Activity 3: Superlative Chain Teacher starts: "Bamboo is one of the most amazing plants." Ss take turns in order of seats, each needing to make sentences with different structures. 完成 3c 短文补全 参与 “竹子特性 PK 赛”,用最高级描述竹子特性并进行判断。 参与 “最高级接龙” 活动,快速反应造句。 通过语篇补全和竞争性活动,将语法知识从 “单句” 提升到 “语篇” 和 “交流” 层面,结合竹子主题强化应用。 通过接龙游戏趣味回顾全课内容,系统梳理知识,强化记忆,帮助学生形成清晰的知识框架。
效果评价:组评 + 师评。教师观察学生是否能主动进行小组合作并梳理总结出主要内容和句型,及时提供帮助。教师观察学生在班内运用所学语言交流的情况,给予鼓励或帮助,评价教与学的成效。
Part 5: Summary(2min) Summarize the key content in this lesson. 跟随教师回顾知识点,在笔记本上补充思维导图 总结本课所学内容,巩固加深印象。

Part 8: Exercises(3min) T assigns the test. 完成课堂练习。 让学生在课上练习消化知识点,及时操练重点知识点和目标语言,让教师把握学情。
Part 9: Homework 基础作业: 抄写并背诵不规则最高级表,并用竹子相关词汇造句 提升作业: 用最高级写 5 句关于 “竹子” 的句子 拓展作业: 和家人讨论 “家里最特别的植物”,用英语记录对话(至少 3 句)。 将家庭作业做好记录。 作业布置落实双减政策,减量不减质,重视实际场景的交际应用,减轻机械操练。
板书设计
教学反思 本节课通过 “情境引入 - 规则感知 - 练习巩固 - 语篇应用” 的流程,将最高级语法知识与 “动植物描述” 主题及竹子特性紧密结合,融入趣味活动,学生参与度较高。但仍存在以下问题:部分学生对 “多音节词” 的判断不清晰(如 “happy” 误认为多音节词,错用 “most happy”);3c 短文中 “one of the + 最高级 + 复数” 结构的运用错误较多(漏 “the” 或名词未用复数);“竹子特性 PK 赛” 中部分小组描述范围不够明确,需加强对 “范围状语” 的强调。 后续教学中,需增加 “单 / 多音节词区分” 的专项练习(如给出单词让学生分类),设计更多包含 “one of...” 结构的语篇填空,强化语境应用;同时在活动中明确要求 “必须包含范围状语”,提升表达准确性。
