教科版六年级上册 Unit 4 Cat or Dog? 单元解读 一、新课标理念体现 本单元话题为“选择宠物与比较决策”（choosing a pet and making a decision），围绕了解猫和狗的异同、根据自身条件权衡选择、关爱照顾宠物展开，属于“人与自然”主题范畴“自然生态、环境保护、灾害防范、宇宙探索”主题群，涉及“种植与养殖，热爱并善待生命”子主题——教材以What do you need to think about before getting a pet? Is your home better for a cat or a dog? Why?为单元问题，在Get Started板块以猫狗习性图片分类活动引导学生认识猫狗行为差异（sleep during the day / play during the night vs go for a walk / don’t like to be alone），在Close Reading板块以选择宠物指南呈现比较框架（space / habits / cleaning / family），在Your Turn板块以Ms Wills想养猫或狗为情境要求学生根据其生活条件做出推荐并写信说明理由，在Portfolio板块要求学生根据自身家庭条件选择适合的宠物并阐述理由——培养学生关爱动物、理性选择、负责任饲养的意识；同时涉及“人与自我”主题范畴“生活与学习”主题群，“健康、文明的行为习惯与生活方式”子主题——单元贯穿“根据生活方式选择宠物”这一线索，Close Reading指南从space（居住空间）、habits（生活习惯如light sleeper）、time（时间安排如busy at work）三个维度引导学生思考自身生活方式与宠物需求的匹配关系，Your Turn的Ms Wills案例（lives alone / nearest park is a 10-minute walk / busy in the morning but gets home early / has a lot of free time in evenings and on weekends / not a light sleeper）正是生活方式与宠物选择匹配的实践，培养学生理性评估自身条件、做出负责任决策的能力。六年级属新课标二级（5~6年级），二级要求学生“能就熟悉的话题进行简单的交流”“能在语境中理解并运用常见表达”——本单元通过Get Started（猫狗习性分类与Yiming-Nikki对话跟读）、Close Reading（选择宠物指南阅读与维恩图比较填写）、Active Listening（Yiming家庭条件与猫狗习性匹配听力与图表填写）、Your Turn（Ms Wills案例分析与建议信写作）、Portfolio（自身家庭条件与宠物选择工作纸）、Spotlight（冠词与比较句式聚焦）和Wonderland（Long i语音学习与宠物关爱阅读）七个板块的递进设计，让学生在选择宠物的真实情境中综合运用比较句式和冠词，体现新课标“在真实情境中综合运用语言”的理念。 二、课时划分 第1课时：Get Started & Close Reading（教材第38—41页） 第2课时：Active Listening—Wonderland（教材第42—48页） 三、单元内容分析 本单元由Get Started、Close Reading、Active Listening、Your Turn、Portfolio、Spotlight和Wonderland七个板块构成，课时之间呈现从猫狗习性语块输入与对话跟读（Get Started的习性图片分类与Yiming-Nikki对话跟读）到比较阅读理解（Close Reading的选择宠物指南阅读与维恩图填写），再到听力训练与条件匹配（Active Listening的Yiming家庭条件与猫狗习性匹配听力与图表填写）、写作输出（Your Turn的Ms Wills案例分析与建议信写作）、自我评价（Portfolio自身家庭条件与宠物选择工作纸）、语言聚焦（Spotlight冠词与比较句式）和拓展阅读（Wonderland Long i语音与宠物关爱阅读）的递进逻辑。单元开篇页（教材第37页）呈现单元标题Cat or Dog?和单元问题What do you need to think about before getting a pet? Is your home better for a cat or a dog? Why?，设三条单元目标：Describe the differences between cats and dogs / Talk about the things you need to think about when choosing a pet / Use different ideas to make a decision。 第1课时涵盖Get Started和Close Reading两个板块。Get Started板块（教材第38—39页）承担猫狗习性语块输入功能，以了解猫和狗的行为特点为情境。Task A以图片分类活动呈现猫狗习性差异——猫（play during the night / sleep during the day / stay inside）与狗（go for a walk / don’t like to be alone / lose hair / love playing with toys），训练学生观察和分类动物行为特征的能力。Task B为听力任务，训练学生听Nikki描述她的宠物并猜测是猫还是狗。Task C提供Yiming和Nikki的对话跟读语篇——Yiming想养宠物，询问养猫的感受（What’s it like to have a cat?），Nikki分享她的猫的习惯（My cat follows me everywhere. / She does sleep a lot during the day. But she wakes up to play with me when I get home from school. / Not very much.），呈现养宠物的真实体验。Tell me more板块提供讨论猫狗习性的对话模板（What’s it like to have a cat/dog? / Well, most cats/dogs like to ... They don’t like to ...）。Chunk Store输入语块eat treats / dig holes in the ground / climb on things / go for a walk twice a day / stay inside。Close Reading板块（教材第40—41页）为主课文阅读板块，以选择宠物指南为情境。Task A呈现一篇说明文语篇——从space（Cats stay inside most of the time. However, dogs need to go for a walk at least twice a day.）、habits（Most cats like to sleep during the day and play during the night. If you are a light sleeper, think twice before getting a cat.）、cleaning（You need to clean dogs often. Unlike dogs, cats usually clean themselves.）、common traits（They both love playing with toys. They both lose hair, too.）和family（make sure your family is OK with the idea, too!）五个维度提供选择宠物的思考框架——呈现比较说明文的写作结构。Think板块（What do you need to think about before getting a pet?）培养归纳思维。Task B要求学生填写猫狗异同维恩图——Cats和Dogs两个圆的交集为共同点（both love playing with toys / both lose hair），各自独有部分为差异点——训练比较与分类的信息提取能力。Tell me more板块提供讨论猫狗异同的对话模板（What do you think is different between cats and dogs? / ... is ... However, ... is ... / What do they have in common? / Well, they are both ... and they ..., too.）。Sentence Bank提供比较句式（... and ... are both ... / ... and ... are alike/different because ... / ... are ..., while ... are ...）。 第2课时涵盖Active Listening至Wonderland五个板块。Active Listening板块（教材第42—43页）为听力训练课，以Yiming家庭条件与猫狗习性匹配为情境。Task A呈现Yiming家庭信息（very busy at work / an animal lover / a light sleeper / likes to go to the park / goes to school early），要求学生判断猫或狗更适合他的家庭。Task B为听力任务，要求学生听Yiming和Nikki讨论养猫的对话并填写猫的习性表（love playing with toys / clean themselves / play during the night）和Yiming家庭条件匹配表（good for keeping a cat / not good for keeping a cat）。Task C要求学生听Yiming对养狗的思考并填写狗的习性表和家庭条件匹配表。Tell me more板块提供讨论Yiming应该养什么宠物的对话模板（So, what pet do you think Yiming should get? / I think he should get ... because ... / The way I see it, it’s better for him to get ... because his ... often ... / Good point! And there is ... near their house, so ... / Yes, that makes sense. / No, I don’t think that would work. / I agree with you. / I don’t agree.），引入同意与不同意的表达。Your Turn板块（教材第44—45页）为写作输出课。Task A呈现Ms Wills（来自加拿大的新老师）的信息——lives alone in the city / nearest park is a 10-minute walk / many tall buildings / busy in the morning but gets home early / has a lot of free time in evenings and on weekends / not a light sleeper——要求学生根据信息帮助她做猫或狗的选择。Tell me more板块提供讨论Ms Wills应该养什么宠物的对话模板（So, what do you think? Any ideas? / The way I see it, ... is better for Ms Wills, because ... / I agree. On top of that ... / I don’t agree because ... / For these reasons, I think ... is better for Ms Wills.）。Task B要求学生给Ms Wills写建议信——I know you want to get a pet but are not sure which one to choose. I think I can help you with that. / What do you think she should get? Why do you think so? / Hope this helps!——训练运用比较框架完成建议信写作的能力。Chunk Store输入语块not a light sleeper / no space to play / too far away / get home early / have free time / take care of / for the same reason。Sentence Bank提供建议信句式（If you don’t have much time to ... / It’s better for you to get ... because ... / In short, I think ...）。Portfolio板块（教材第46页）为自我评价板块，要求学生根据自身家庭条件选择适合的宠物并填写工作纸——从Time / Space / Habits三个维度分析（A ___ is better for my family, because a ___ is ___. And I have the time to ___. It ___. I can ___ to take care of it.）。More ideas提供思考想要或不想要的宠物并写出至少三个理由、调查同学的宠物偏好的延伸任务。Spotlight板块（教材第47页）为语言聚焦板块，总结三组核心句式——冠词（My friend has a cat. It is an orange cat. / Oh, no! The cat pushed the cup off the table!——呈现a/an不定冠词首次提及与the定冠词再次提及的用法），比较句式（They both love ... / They are both ... / Unlike ..., ... like to ... / ... are ..., while ... are ...），同意与不同意的表达（I agree. / I don’t agree because ... / I think it’s better to ...），配以It’s not a toy! I think it’s better to drink it instead.的餐桌对话示例。Wonderland板块（教材第48页）为拓展阅读板块，设Hi! Phonics语音板块（Long i：ime族time/lime/prime、ike族bike/hike/like、ive族five/dive/live、ine族nine/line/fine）和宠物关爱阅读语篇——When we welcome pets into our home, they become part of our family. Give them a lot of love and care. That’s what family does. It is also our job to make sure they are happy and well. What’s more, we shouldn’t be mean to them just because they are not humans. Always be there for them. Show them your love, and they will love you back.——将单元主题从“比较选择”延伸到“关爱与责任”，引导学生认识到选择宠物不仅是比较决策，更是一份对生命的长期承诺。 四、单元教学目标 通过本单元的学习，学生能够：在语言知识方面，掌握猫狗习性语块——sleep during the day / play during the night / stay inside / go for a walk / don’t like to be alone / lose hair / love playing with toys / clean themselves / eat treats / dig holes in the ground / climb on things / go for a walk twice a day，掌握比较句式——... and ... are both ... / ... and ... are alike/different because ... / ... are ..., while ... are ... / They both love ... / They are both ... / Unlike ..., ... like to ...，掌握冠词a/an/the的基本用法——a cat（首次提及，不定）vs the cat（再次提及，定）vs an orange cat（元音前用an），掌握同意与不同意的表达——I agree. / I don’t agree because ... / I think it’s better to ... / Yes, that makes sense. / No, I don’t think that would work.，掌握建议信句式——If you don’t have much time to ... / It’s better for you to get ... because ... / In short, I think ...，掌握决策语块——not a light sleeper / no space to play / too far away / get home early / have free time / take care of / for the same reason / make a decision / think twice before，感知关键语块follow me everywhere / light sleeper / think twice / space / habits / clean / unlike / in common / welcome pets into our home / be mean to / be there for them；在语言技能方面，能用比较句式描述猫狗的异同，能用维恩图整理比较信息，能阅读选择宠物指南并提取比较信息，能听音判断家庭条件与猫狗习性的匹配度，能根据个人条件写建议信推荐适合的宠物，能用Time / Space / Habits三维度分析自身家庭适合的宠物；在文化意识方面，感受“亲亲而仁民，仁民而爱物”的博爱胸怀，理解“鱼与熊掌不可得兼”的权衡智慧；在思维品质方面，通过维恩图比较培养分类与交集思维，通过Close Reading指南的五维度框架培养多维分析思维，通过Active Listening条件匹配培养匹配推理思维，通过Your Turn建议信写作培养论据支撑决策的论证思维，通过Wonderland阅读语篇从“比较选择”到“关爱与责任”的延伸培养责任思维。 五、单元重难点 重点：​ 掌握猫狗习性语块与比较句式——sleep during the day / play during the night / stay inside / go for a walk / clean themselves / lose hair / ... and ... are both ... / Unlike ..., ... like to ... / ... are ..., while ... are ... 掌握冠词a/an/the的基本用法——a cat（首次提及，不定冠词）vs the cat（再次提及，定冠词）vs an orange cat（元音音素前用an）——能在语境中正确使用不定冠词与定冠词 掌握同意与不同意的表达——I agree. / I don’t agree because ... / I think it’s better to ... / Yes, that makes sense. / No, I don’t think that would work.——能在讨论中表达立场并说明理由 难点：​ 维恩图的比较信息提取——Close Reading Task B要求学生从选择宠物指南中提取猫狗的异同并填入维恩图，交集为共同点（both love playing with toys / both lose hair），各自独有部分为差异点——需理解文本中的比较结构（However / Unlike / both） 家庭条件与宠物习性的匹配推理——Active Listening要求学生听音后判断Yiming家庭条件（very busy at work / a light sleeper / likes to go to the park）与猫狗习性的匹配度，需综合多个条件进行推理判断 从比较分析到建议信写作的迁移——Your Turn Task B要求学生根据Ms Wills的生活条件分析后写出完整的建议信，需在比较框架基础上自主组织论据并完成书信格式写作 冠词a/an/the的语境选择——Spotlight Tip 1引入冠词系统，学生需区分首次提及用a/an、再次提及用the、元音音素前用an，这是六年级新增的语法点，需在语境中反复操练 六、学情分析 六年级学生对宠物话题有天然兴趣，猫和狗是学生最熟悉的两种动物，单元问题What do you need to think about before getting a pet?直接关联学生的生活经验和愿望，代入感强。学生在U1学习了情绪管理，在U2学习了同伴冲突解决，在U3学习了亲子沟通，本单元从人际交往转向人与动物的关系——从“与人沟通”延伸到“选择和关爱宠物”。人称代词在U1/U2已学宾格（I/me, we/us, they/them），在U3已学物主代词（my, his, her, our, their），本单元引入冠词a/an/the——这是六年级新增的语法点，学生需理解不定冠词（首次提及）与定冠词（再次提及）的功能差异，以及在元音音素前使用an的规则。Close Reading Task B的维恩图要求学生从说明文中提取猫狗异同信息——这对六年级学生的比较阅读和信息分类能力有较高要求。Active Listening的条件匹配任务要求学生综合Yiming家庭的多个条件（very busy at work / a light sleeper / likes to go to the park）与猫狗习性进行匹配推理——这对六年级学生的是多条件综合判断能力有较高要求。Your Turn Task B的建议信写作要求学生在比较框架基础上自主组织论据并完成书信格式写作——从比较分析到论据支撑决策的写作迁移对六年级学生的语言综合运用能力有较高要求。Wonderland的阅读语篇提出we shouldn’t be mean to them just because they are not humans——引导学生从“比较选择”延伸到“关爱与责任”——这一价值观跨越需要教师引导。 七、教学策略 情境教学法——创设“选择适合的宠物”的真实情境，让学生在模拟的宠物选择场景中操练语言——如看图分类猫狗习性（Cats sleep during the day. / Dogs go for a walk.）、跟读Yiming-Nikki对话（What’s it like to have a cat? / My cat follows me everywhere.）、角色扮演讨论宠物选择（The way I see it, it’s better for him to get ... because ...）——学生在情境中自然使用比较句式和冠词；教师可在课堂展示猫狗图片或短视频，营造动物认知和比较决策的氛围。 任务驱动法——本单元每个板块均以Task A / Task B / Task C的任务结构推进：Get Started的Task A要求看图分类猫狗习性，Close Reading的Task B要求填写维恩图比较异同，Active Listening的Task B/C要求听音填写条件匹配表，Your Turn的Task B要求写建议信——每个任务有明确的语言输出目标，任务产出可独立检查。 合作学习法——Get Started的Tell me more（讨论猫狗习性）、Close Reading的Tell me more（讨论猫狗异同）、Active Listening的Tell me more（讨论Yiming应该养什么宠物）、Your Turn的Tell me more（讨论Ms Wills应该养什么宠物）均设计为pair work或group work，学生在合作中互问互答、角色扮演、分享观点——Portfolio的More ideas中What about your classmates? What pets do they want or don’t want?明确要求学生与同学调查交流。 直观演示法——利用Get Started Task A的猫狗习性图片直观呈现动物行为差异，利用Close Reading Task B的维恩图直观呈现猫狗异同的交集与差集关系，利用Active Listening的猫狗习性表和家庭条件匹配表直观呈现条件与习性的对应关系，利用Spotlight的冠词例句（a cat → an orange cat → the cat）直观呈现冠词用法的递进——教师可在课堂展示猫和狗的实物图片或视频，帮助学生将习性语块与动物行为对应。 比较教学法——本单元从标题Cat or Dog?开始即以比较为核心驱动：Get Started Task A比较猫狗习性图片（sleep during the day vs go for a walk），Close Reading Task B用维恩图比较猫狗异同（both ... / unlike ... / while ...），Active Listening比较Yiming家庭条件与猫狗习性的匹配度，Your Turn比较Ms Wills的生活条件与猫狗需求的匹配度，Spotlight Tip 2聚焦比较句式（They both love ... / Unlike ..., ... like to ... / ... are ..., while ... are ...）——整个单元围绕“比较”这一核心思维展开，从直观比较（图片分类）到文本比较（维恩图）到条件比较（匹配推理）到论证比较（建议信写作）逐步提升——教师在教学中应始终凸显比较视角，引导学生用比较句式描述异同、用比较框架组织信息、用比较结果支撑决策。 八、教学准备 教师准备：教材配套音视频资源（2个课时的听力音频，含Get Started Task B、Active Listening Task B/C），猫狗习性图片卡（sleep during the day / play during the night / stay inside / go for a walk / don’t like to be alone / lose hair / love playing with toys / clean themselves），比较句式卡（... and ... are both ... / Unlike ..., ... like to ... / ... are ..., while ... are ... / They both love ... / They are both ...），冠词教学卡（a cat / an orange cat / the cat），维恩图模板（Cats / Dogs / 交集），家庭条件与宠物习性匹配表模板，同意与不同意表达卡（I agree. / I don’t agree because ... / I think it’s better to ...），建议信写作模板（Dear ... / I know you ... / What do you think ...? / Why ...? / Hope this helps! / Best wishes），决策语块卡（not a light sleeper / no space to play / get home early / have free time / take care of / for the same reason），Long i语音卡（ime/ike/ive/ine词族），Portfolio宠物选择工作纸模板。 学生准备：想想自己家里有没有养宠物（或想不想养），是什么宠物、平时谁负责照顾；想想自己更喜欢猫还是狗，能说出两三个理由。 九、跨学科整合建议 数学：维恩图与分类比较——本单元Close Reading Task B要求学生将猫狗的异同填入维恩图——猫和狗各自独有的习性填入两侧圆内，共同习性填入交集区域（both love playing with toys / both lose hair）——这正是数学课“集合与分类”内容的直接运用。数学课强调“能根据事物特征进行分类，理解集合的交集与并集”，而本单元的维恩图正是集合思维在英语学习中的体现——学生需判断哪些习性是猫独有的（sleep during the day / play during the night / clean themselves / stay inside）、哪些是狗独有的（go for a walk / don’t like to be alone / need to be cleaned often）、哪些是共有的（love playing with toys / lose hair），并用比较句式表达——教师可与数学老师合作，在数学课指导学生了解维恩图的基本原理和分类方法，在英语课用... are both ... / Unlike ..., ... like to ... / ... are ..., while ... are ...等句式在维恩图上描述猫狗异同——实现跨学科的分类与交集思维训练。 劳动：宠物饲养与日常照料——本单元以选择宠物为核心情境，涉及宠物日常照料的多项劳动技能——clean dogs often（清洁）、go for a walk twice a day（遛狗）、take care of（照顾）、feed（喂食）——这正是劳动课“劳动习惯与技能，热爱劳动”内容的直接运用。劳动课强调“培养基本的劳动习惯和生活自理能力”，而本单元Close Reading指南提到的You need to clean dogs often. / Dogs need to go for a walk at least twice a day.和Your Turn建议信中的take care of正是饲养劳动在英语学习中的体现——Wonderland阅读语篇进一步提出It is also our job to make sure they are happy and well——强调照料宠物是一份责任——教师可与劳动老师合作，在劳动课指导学生了解宠物饲养的基本劳动技能和日常照料流程，在英语课用clean / go for a walk / take care of / feed等语块描述饲养劳动——实现跨学科的劳动素养培养。 十、文化拓展延伸 “亲亲而仁民，仁民而爱物”——关爱生命的千年智慧：《孟子·尽心上》中孟子说“君子之于物也，爱之而弗仁；于民也，仁之而弗亲。亲亲而仁民，仁民而爱物”——君子对于万物，爱惜它；亲爱亲人而仁爱百姓，仁爱百姓而爱惜万物——这与本单元Wonderland阅读语篇高度契合。孟子提出爱的层次递进——从爱家人到爱众人到爱万物——宠物正是“爱物”的典型对象。Wonderland语篇说When we welcome pets into our home, they become part of our family. Give them a lot of love and care.——这正是“亲亲”（宠物成为家人）到“爱物”（give them a lot of love and care）的体现。孟子还强调“we shouldn’t be mean to them just because they are not humans”——这正是“仁民爱物”中“爱物”的应有之义。教学中可在Wonderland阅读语篇学习后介绍：中国两千多年前孟子就说“亲亲而仁民，仁民而爱物”——从爱家人到爱众人到爱万物——我们学到的pets become part of our family就是“亲亲”，give them a lot of love and care就是“爱物”，we shouldn’t be mean to them just because they are not humans就是“爱物”的底线——选择宠物不仅是比较决策，更是一份对生命的长期关爱。 “鱼，我所欲也；熊掌，亦我所欲也。二者不可得兼”——权衡取舍的千年智慧：《孟子·告子上》中孟子说“鱼，我所欲也；熊掌，亦我所欲也。二者不可得兼，舍鱼而取熊掌者也”——鱼是我喜欢吃的，熊掌也是我喜欢吃的；如果不能两样都吃，就舍弃鱼而取熊掌——这与本单元Cat or Dog?的决策主题高度契合。孟子用鱼与熊掌的比喻说明：当两样好东西不能同时拥有时，需要权衡利弊做出选择——这正是本单元选择宠物的核心思维。Close Reading指南从space / habits / cleaning / family四个维度帮助学生权衡猫和狗的利弊，Your Turn要求学生根据Ms Wills的生活条件做出cat or dog的推荐——都是“二者不可得兼”的实践。教学中可在Your Turn Task A完成Ms Wills案例分析后介绍：中国两千多年前孟子就说“鱼，我所欲也；熊掌，亦我所欲也。二者不可得兼”——当两样好东西不能同时拥有时，要权衡利弊做选择——我们学到的It’s better for you to get ... because ...就是在权衡猫和狗的利弊后做出选择，这就是“舍鱼而取熊掌”的智慧——根据自身条件，选择最适合的那一个。 第 1 页 共 9 页 学科网（北京）股份有限公司 $
