Unit 1 Feeling good Period 2 Grammar activity教学设计 教学基本信息 单元名称 选择性必修第一册Unit 1 Feeling good 学科 英语 学段 高中 年级 高二 主要教材 书名：上海教育出版社·沪教版 2020 选择性必修第一册 出版社：上海教育出版社 出版日期：2020年 课时安排 1课时(45min) 课型 语法课 教学设计理念 本课时以 “过去完成时” 为核心语法点，秉持 “语法为表意服务” 的理念，将语法学习与单元主题 “Feeling good”（健康、运动、积极状态）深度融合。通过 “感知 - 归纳 - 应用 - 迁移” 的教学逻辑，引导学生在真实语境中理解过去完成时表示 “过去的过去” 的时间关系：从对比一般过去时与过去完成时的差异切入，结合健康、运动等主题的例句分析规则，再通过分层练习和小组任务巩固应用，最终实现语法知识向语言能力的转化。注重培养学生的逻辑思维（时间顺序分析）和自主学习能力，通过合作任务和真实语境运用，让语法学习更具实用性和趣味性。 教材分析 【What】本课时聚焦过去完成时的语法教学，涵盖其形式（had + 过去分词）、核心用法（表示 “过去的过去”，即一个动作在另一个过去动作之前发生）、与一般过去时的区别（时间顺序是否明确）及语境应用（如健康、运动场景中的动作描述）。配套活动包括例句对比、填空练习、句子补全、小组合作分析文本及主题写作。 【Why】通过过去完成时的学习，帮助学生精准描述过去动作的先后关系，提升叙事的逻辑性；结合 “健康、运动” 主题，使语法学习与生活实践关联，增强语言表达的真实性和实用性。 【How】教材以 “问题驱动 - 规则归纳 - 练习巩固 - 主题应用” 为逻辑链：先通过简单例句对比引出过去完成时（如 “到达派对时，客人已离开”），再通过文本例句分析时间关系，最后设计分层练习和小组任务，逐步深化对语法点的理解和运用。 学情分析 1. What I know 词汇方面：已掌握与健康、运动相关的基础词汇（如 exercise, health, train 等）。 语法方面：已熟练掌握一般过去时，能描述过去发生的动作，但对 “过去的过去” 的时间关系认知模糊，未系统接触过去完成时。 背景知识方面：对 “健康习惯、运动经历” 有生活体验，能简单叙述过去的事件，但难以精准表达动作的先后顺序。 2. What I want to know 如何区分一般过去时与过去完成时；过去完成时在具体语境（如叙述运动经历）中的正确用法；何时必须使用过去完成时，何时可省略。 3. What I learned 主题内容方面：能用过去完成时描述健康、运动相关的过去事件，清晰表达动作先后 语言知识方面：掌握过去完成时的形式和用法，能在语境中准确区分与一般过去时的差异。 教学目标 1. 语言能力 ①掌握过去完成时的构成（had + 过去分词）及基本用法（表示 “过去的过去”）； ②能在具体语境中正确使用过去完成时，区分其与一般过去时的时间关系（如 “By the time I arrived, they had left”） 2. 学习能力 ①学会通过例句对比、时间轴分析等方法归纳语法规则； ②能在小组合作中梳理动作顺序，提升自主探究和合作学习能力。 3. 文化意识 了解不同语境中 “健康生活” 的表达差异，增强跨文化交流中时间关系描述的准确性。 4. 思维品质 ①培养逻辑思维，能分析多个过去动作的时间先后顺序； ②提升语境推理能力，判断何时需用过去完成时以明确语义。 教学重难点 教学重点 ①过去完成时的构成（had + 过去分词） ②“过去的过去” 的时间关系（即动作 A 在动作 B 之前发生，且均为过去）。 教学难点 ①在无连词提示的语境中，正确判断并使用过去完成时 ②区分何时必须使用过去完成时，何时可因顺序明确而省略（如含 “after”“before” 等连词时） 教学资源 课件PPT，黑板、白板。 教学活动设计 教学过程 活动形式及步骤 活动意图 时间 学习理解 Activity 1 Lead in 1.What’s the function of past tense? I played football yesterday. 【答案】Time：yesterday Played：It’s used to talk about past actions. 2.If there are two past actions, how to show which one happened earlier? She the party before I . 【答案】had left；arrived​​ the past perfect ●通过简单例句（如 “I played football yesterday” 与 “She had left before I arrived”）对比，引发学生对 “动作先后顺序” 的关注，自然引出 “过去完成时” 的概念，为后续学习铺垫。 3min Activity 2 Knowledge explanation: What is The past perfect tense ? I suddenly realized that I had left my mobile phone at home. 【答案】realized：一般过去时（过去的动作） had left ：在 realized 之前就已经发生的动作 The past perfect tense: When we talk about the past, we can use the past perfect to refer to an even earlier point in time “过去的过去” —— 即一个动作在另一个过去动作 / 时间之前已经发生。 1. Observation + Comparison 1) Look at the sentences from the text and answer the questions. Sentence ¹: For years, people had linked the two, but it was only in the 1960s that solid scientific evidence started appearing. Sentence ³:The students who had exercised did 10% better... than those who hadn’t stepped on the treadmill ①What is the form of the past perfect tense? 【答案】had + past participle ②What is the time relationship of the past perfect tense?【答案】The past perfect tense describes an action that occurred earlier in the past than another past event or time (often expressed by the simple past tense). a In the decades that followed, study after study confirmed what the ancient poet had already known b She went to bed after she finished her homework. ③What is the difference between the two sentences? 【答案】Sentence a uses the past perfect because there’s no conjunction to clarify the earlier past action.Sentence b uses simple past because the conjunction after already makes the time order clear. 2. Discovery and Summary The past perfect is often used together with the simple past. a The past perfect verb shows what happened __________ (before / after) the event or action in the simple past. b We don’t need to use the past perfect form of the verb if the order is clear. In that case, we can use for both events. 【答案】before；the simple past ●结合文本例句（如 “People had linked the two, but it was only in the 1960s...”），明确过去完成时的形式、“过去的过去” 的时间关系及与一般过去时的区别，帮助学生建立语法规则的系统性认知。 14min Activity 3 Practice 1.用所给此的适当形式填空 1.By the time we arrived at the theater, the actor (acknowledge) the audience’s applause. 3.

Record them in a table to analyze which action happened first. 过去完成时句子 一般过去时句子 谁先发生？ Task 2: Work together to summarize the past perfect + simple past pattern. 提供公式填空： 过去完成时（动作 A，______发生） + 一般过去时（动作 B，______发生） → 明确 “过去的过去” 逻辑。 对比分析文章例句，讨论 “为何动作 A 要用过去完成时，动作 B 用一般过去时？” Task 3: Use it to write sentences about health, exercise, or learning (like the text’s theme). 提供公式： By the time our school __________ (hold) the sports day, we __________ (train) for months. When the doctor __________ (advise) a diet change, she realized she __________ (ignore) health warnings. Task 4:Present your sentences/scenes. Peers evaluate grammar, time logic, and creativity. Category Criteria Example (Correct/Incorrect) Grammar Correct past perfect structure √ They had exercised before the exam. × They have exercised before the exam. Time Logic Clear “past of the past”order √ After he had practiced, he won the race. Creativity About the health/exercise (text theme) √ By the time we changed habits, our energy had improved. ●小组合作从文本中提取过去完成时与一般过去时的句子，通过表格分析动作顺序，深化对语法规则的理解； 结合 “健康、运动” 主题造句（如 “By the time the sports day held, we had trained for months”），实现语法知识向主题表达的迁移。 7min 应用实践 Activity 5 Summary 以思维导图的形式，整理要点。 ●使用思维导图帮助学生系统化地掌握语法结构。 2min Activity 6 Assessment 展示评价表，供学生对自己本节课中的表现及所学情况进行自我评价. ●通过自我评价，帮助学生了解自己的学习情况，提高学习的积极性和主动性。 2min 迁移创新 作业内容 作业设计意图 2min 本节课作业二选一，为分层作业，难度有所区别。基础一般的同学可以选择作业一，基础较好的同学可以选择作业二。 Compulsory work： Use these passage-related verbs (link, confirm, exercise, improve, abandon) to write 5 sentences with the past perfect, focusing on health/exercise. 【答案】 1. By the time the new research confirmed the benefits of exercise, scientists had already linked physical activity to mental health. 2. Before the experiment confirmed that exercise boosts memory, researchers had analyzed thousands of data points. 3. By the time the athlete competed in the marathon, she had exercised rigorously for six months. 4. By the time Tom noticed his energy levels rise, he had already improved his diet and exercise routine for weeks. 5. Before the doctor advised him to quit smoking, he had already abandoned the harmful habit on his own. Optional work ： Interview friends about their health habits. Ask questions like: “Before you started [a habit, e.g., jogging], had you tried other ways to stay healthy?” Record 3 sentences with the past perfect from their answers. Share your sentences with them to check accuracy. ●必做任务（用指定动词写句子）强化过去完成时与主题的结合； 选做任务（采访朋友健康习惯）将语法应用于真实交流，提升语言运用的灵活性和真实性。 板书设计 选择性必修一 Unit 1 Feeling good Grammar activity 教学反思 优点：教学活动紧扣 “过去的过去” 核心逻辑，从对比导入到主题应用层层递进，符合学生认知规律，分层练习和小组任务兼顾不同水平学生，有助于个性化学习。 缺点：小组活动中，少数学生依赖同伴，自主分析时间关系的能力不足。 改进：小组任务前提供 “时间轴工具”，帮助学生可视化动作顺序，降低分析难度。 1/11 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $$
