二、设计背景与意图
(一)课标依据
《义务教育英语课程标准(2022年版)》以核心素养为统领,倡导在主题意义引领下,通过“学习理解—应用实践—迁移创新”的英语学习活动观组织教学,落实“学思结合、用创为本”。本作业选取“人与自我”主题范畴下“生活与学习”主题群中的“健康生活方式”子主题,以“认识健康食物—讲述健康生活—调查身边的生活方式—提出健康建议”的真实语言实践为路径,引导学生在用英语谈论健康话题的过程中实现语言能力、文化意识、思维品质和学习能力的协同发展。课标要求学生能读懂介绍健康生活方式的说明性语篇,能借助连接词when与because表达时间与因果,能在语境中正确使用健康类词汇,并初步形成主动关注自身健康、合理饮食、坚持运动的意识与习惯。
(二)教材分析
本作业对应沪外教版(2024新教材)七年级上册 Unit 3 Be healthy, be happy。单元属“人与自我”主题范畴,聚焦“健康饮食、运动、睡眠与快乐生活”,单元核心问题是 What makes a healthy lifestyle?,按 A Getting ready — B Reading and critical thinking — C Grammaring — D Listening and speaking — E Writing — F Project 的板块递进结构编排,主要语言知识如下:
(1)板块一:A Getting ready。以 Keeping a healthy diet 为主题,对比 Ava 与 Henry 的三餐。Ava 早餐吃面包、牛奶和鸡蛋——They give her energy and keep her active;午餐吃肉或鱼——It makes her strong;晚餐吃色拉、黄瓜和胡萝卜,并强调每天至少吃五种果蔬。Henry 早上只吃一个鸡蛋,午餐爱吃汉堡、薯条和可乐(unhealthy but taste good),还常在饭前吃油炸食品和蛋糕,很少吃正餐。由此引出健康与不健康食物分类表,并讲解前缀 un-:unhappy、unkind、unhealthy。
(2)语篇一:B Reading and critical thinking 的主阅读 Wendy's healthy life。第一段介绍 Wendy 是家附近的一名中学生,她 takes good care of herself;第二段写她步行上学、在食堂吃健康食物,junk food like chips or candies is rarely her choice;第三段写她喜欢运动,每周游泳一次,周末和朋友骑车去 country park,她感叹 I feel free like a bird when I'm cycling;第四段写她学习努力却从不熬夜,每晚睡八小时,because she believes enough sleep keeps her active;第五段总结 Eating healthy food, doing sports, and having a good sleep not only give Wendy a healthy life but also make her a happy girl。语篇重点训练 skimming and scanning,并借助结构图 Introduction→Body→Conclusion 找出三段主题句。
(3)板块三:C Grammaring(本单元核心语法:when 与 because 引导的状语从句)。教材借主阅读中的句子——She feels free when she cycles. / She rarely eats junk food because it is unhealthy.——引导学生观察并归纳。语法要点分两层:when 引导时间状语从句,意为“当……时”,从句可放主句之前或之后,放句首时用逗号与主句隔开;because 引导原因状语从句,意为“因为”,用来回答 why 的提问,从句常在主句之后。需特别辨析 because 与 so 不能同时使用,以及 because 后接句子、because of 后接名词或动名词。
(4)板块四:D Listening and speaking。以 Visiting a doctor 为主题,Xiao Peng 因咳嗽、发烧、头痛去看医生,学习疾病词汇 cough, fever, headache, runny nose, sneeze, sore throat,并角色扮演医生与病人,练习看病时的常用语句;同时操练 /s/ /z/ /ts/ /dz/ 的发音。
(5)板块五:E Writing。写作任务为 Billy's healthy life,要求以图片为依托对比比利的过去与现在——过去他吃 chips、喝 cola、no exercise、睡得晚,现在吃 salad、fruit、坚持 cycle 与 swim、每天睡八小时;写作中练习使用连接词 and, but, when, because 使句子衔接自然。
(6)板块六:F Project。Design a lifestyle survey(设计生活方式调查表)。学生分组设计一份调查表,涵盖饮食、作息、锻炼、快乐事四个方面,在班级内开展调查、汇总数据并展示结果,在真实的交流中练习本单元的目标语言。
(7)核心词汇与短语:healthy, unhealthy, diet, energy, active, strong, salad, cucumber, carrot, fruit, junk food, sugar, habit, rarely, exercise, swim, cycle, sleep, countryside, patient 等;keep a healthy diet, give sb. energy, keep sb. active, make sb. strong, at least, junk food, be good for / be bad for, take care of, take exercise, once a week, at weekends, country park 等。
(8)单元输出:能用英语说出健康与不健康的食物;能用 when 与 because 说明时间与原因;能读懂介绍健康生活方式的语篇并梳理其结构;能写一篇约80词的短文介绍自己的健康生活并设计一份健康生活方式调查表。
(三)学情分析
七年级学生的健康话题与其日常生活密切相关——他们也爱吃汉堡、薯条和可乐,也会熬夜、缺少运动,“怎样才算健康生活”这一话题贴近他们的真实体验,参与热情较高;但语言运用上仍存在明显薄弱环节。
(1)已有基础:小学阶段已积累 egg, milk, bread, apple 等食物类词汇和 I like ... 等简单表达,对一般现在时和情态动词 should 的用法有初步感知,能说简单的健康建议句。
(2)存在困难:when 与 because 是从属连词,学生第一次系统接触从句,容易混淆二者的含义(把 because 写成 so)、弄错从句的位置与标点,或在 because 与 because of 之间混用;健康类词汇中 salad, cucumber, carrot, junk food, rarely 等较为陌生,拼写也不熟练;energy, sugar 等不可数名词的用法也容易出错。
(3)心理特点:具象思维仍占优势,乐于参与游戏、角色扮演、小组合作等活动,但注意力集中时间有限;部分学生因基础薄弱存在怕开口、怕说错的畏难情绪,需要设计低门槛、有支架的表达任务。
(四)设计意图
(1)真实情境驱动,任务统领全篇。以“认识健康食物—了解健康生活方式—调查身边的饮食习惯—提出健康建议”为情境,把词汇、语法、阅读与写作练习统整到“认识—归纳—表达—分享”这一任务链条中,让学生在“做中学、用中学”。
(2)分层进阶,减负增效。A层为基础巩固,人人必做;B层为能力提升,按需选做;C层为拓展创新,鼓励挑战。三层任务难度递进、彼此关联,允许学生依据自身水平选择,体现差异化与选择性。
(3)健康导向,价值引领。借助 Ava 与 Henry 的三餐对比、Wendy 的健康生活与比利的变化,引导学生在语言运用中反思自己的饮食、运动与作息习惯,体会“健康生活,快乐成长”,实现语言学习与健康教育的融合。
(4)以评促学,学评一体。以量规引导学生明确“什么是好文章”“什么是好建议”,在自评、互评中反思改进,形成“学习—表达—评价—改进”的完整学习闭环。
(5)数形结合,跨学科融通。C 层调查表任务引导学生用数据(频率、时长、比例)描述调查结果,把英语表达与统计意识结合起来,培养整理信息、分析结果与用数据说话的能力。
三、作业目标

(三)思维品质
①在观察主阅读语篇例句、归纳 when 与 because 引导的状语从句用法过程中,发展观察、比较与归纳能力。
②借助 Ava 与 Henry、比利过去与现在的对比,以及调查数据的整理与分析,提升对比分析、因果推理与用证据支持观点的能力。
(四)学习能力
①能借助结构图、句型框架与词库完成短文写作和口头展示,掌握“看连接词判断句间关系”的学习策略。

B2 阅读下面的短文,根据短文内容回答问题。(每题2分,共10分)
How to Stay Healthy and Happy
Do you want to be healthy and happy? Here is some advice from Dr Li, a doctor in a big hospital.
First, eat well. You should have three meals a day and never skip breakfast. Try to eat at least five kinds of vegetables and fruit every day, because they give you energy and vitamins. Stay away from junk food like hamburgers and cola. They taste good, but they are bad for your health.
Second, move more. Exercise is important for everyone. You do not need to do difficult sports. Walking to school, cycling in the country park or swimming once a week can all keep you active. When you exercise, your body becomes stronger and your mind becomes clearer.
Third, sleep enough. Many students stay up late to play games or do their homework, but this is not a good habit. You should sleep for about eight hours every night. Enough sleep keeps you energetic the next day.
Finally, keep a happy heart. Talk with your parents or friends when you feel unhappy. Remember: a healthy life is not only about your body, but also about your mind. Eat well, move more, sleep enough and smile often—then you will be a healthy and happy person.
1. How many meals a day does Dr Li advise us to have?
2. Why should we eat vegetables and fruit every day?
3. What can keep us active? Please give two examples from the passage.
4. How long should students sleep every night?
5. What does the writer want to tell us in the last paragraph?

七、答案与解析
(一)A层 答案与解析
A1 答案与解析
1. healthy 解析:形容词,“健康的”;keep + 宾语 + 形容词,表示“使……保持某种状态”,故用 healthy。
2. unhealthy 解析:形容词,“不健康的”;由句意“吃太多垃圾食品对身体健康不利”可知用含否定前缀 un- 的 unhealthy。
3. fruit 解析:名词,“水果”,作表语;fruit 常作不可数名词,表示水果的总称。
4. salad 解析:名词,“色拉”;a vegetable salad 意为“一份蔬菜色拉”。
5. sugar 解析:名词,“糖”,为不可数名词,故不加 s。
6. rarely 解析:频度副词,“很少”,修饰动词 eats;与后文“想要健康”形成对照。
7. exercise 解析:名词,“锻炼”;take / do (more) exercise 表示“进行(更多的)锻炼”,exercise 作“锻炼”讲时为不可数名词。
8. habit 解析:名词,“习惯”;keep a good eating habit 表示“保持一个良好的饮食习惯”。
9. patient 解析:名词,“病人”;ask sb. to do sth. 表示“要求某人做某事”。
10. energy 解析:名词,“精力、活力”;energy 为不可数名词,be full of energy 表示“精力充沛”。
A2 答案与解析
1. when 解析:when 引导时间状语从句,表示“当天气好的时候”,从句在后,主句在前。
2. When 解析:when 从句放句首时首字母大写,并用逗号与主句隔开,表示“当有空闲时间时”。
3. because 解析:后半句说明“很少吃垃圾食品”的原因,故用 because 引导原因状语从句。
4. because 解析:由“水对健康很重要”可知此处说明原因,用 because。
5. When 解析:表示“当我在乡村公园骑车的时候”,用 When 引导时间状语从句。
6. because 解析:由“没有早起”可知这是迟到的原因,用 because。
7. When 解析:表示“当天气好的时候”,从句放句首,用 When。
8. because 解析:由“她需要足够的休息”可知这是她睡八小时的原因,用 because。
A3 答案与解析
1. A 解析:energy 为不可数名词,不加 s;keep sb. active 表示“使某人保持精力充沛”,active 作宾语补足语,用形容词。
2. B 解析:由常识可知“吃太多垃圾食品对健康有害”,用 be bad for;be good for 意为“对……有益”,与句意相反。
3. C 解析:由“她想保持健康”可知 Wendy 很少吃垃圾食品,用频度副词 rarely。
4. B 解析:由 Why 提问原因,答语用 Because 引导原因状语从句;一句话中 because 与 so 不能同时使用。
5. C 解析:at least 意为“至少”,与本单元“每天至少五种果蔬”的表达一致;at first 意为“起初”,at once 意为“立刻”。
6. C 解析:表示“当我骑车的时候”,用 when 引导时间状语从句;so 表结果,because 表原因,but 表转折,均不合句意。
(二)B层 答案与解析
B1 答案与解析
1. herself 解析:take care of oneself 表示“照顾自己”,主语 She 为女性,故用反身代词 herself。
2. when 解析:表示“当天气好的时候”,用 when 引导时间状语从句。
3. rarely 解析:用副词 rarely 修饰 is 后的表语性判断,表示“很少是她的选择”。
4. cycles 解析:often 提示描写现在的习惯,用一般现在时;主语 she 为第三人称单数,动词用 cycles。
5. cycle 解析:when 引导的时间状语从句描述习惯性动作,用一般现在时;主语 I 后接动词原形 cycle。
6. but 解析:前半句说“学习努力”,后半句说“从不熬夜”,二者为转折关系,用连词 but。
7. because 解析:后句“她相信充足的睡眠让她保持精力充沛”是前句“每晚睡八小时”的原因,用 because。
8. make 解析:主语 Eating healthy food, doing sports and having a good sleep 为三个动名词并列,谓语用复数形式 make。
9. to keep 解析:It is + 形容词 + to do sth. 为固定句型,it 为形式主语,真正的主语是动词不定式 to keep。
10. at 解析:at least 意为“至少”,为固定短语。
B2 答案与解析

My healthy life
I have a healthy life. I eat three meals a day and never skip breakfast, because a good breakfast gives me energy for the whole morning.
I try to eat at least five kinds of vegetables and fruit every day. I rarely eat junk food like hamburgers or chips. When I want a snack, I often have an apple or some yogurt.
I also love sports. I walk to school when the weather is fine, and I swim once a week. At weekends, I often cycle to the country park with my father. It keeps me active and happy.
I sleep for about eight hours every night, so I always feel full of energy the next day. Eat well, move more and sleep enough—that is the secret of my healthy life!
C3 评价要点
①海报要素齐全,插图清晰,建议具体可行、语言正确;②分享内容与海报一致,能正确使用 when 与 because 说明时间与原因,1分钟内完成;③分工明确,能倾听他人并给出建议。
C4 单元高频易错点提示
①when 与 because 的含义不同:when 表时间,意为“当……时”;because 表原因,意为“因为”。判断时看从句与主句之间是“时间”关系还是“因果”关系。
②从句的位置与标点:when 与 because 从句既可放主句之后,也可放主句之前;放句首时必须用逗号与主句隔开(When the weather is fine, she walks to school.)。
③because 与 so 不能同时使用。一个句子中二者只能选其一:Because he was tired, he went to bed early. 或 He was tired, so he went to bed early. 不能说 Because he was tired, so he went to bed early.
④because 后接句子,because of 后接名词、代词或动名词:He didn't come because he was ill. / He didn't come because of his illness.
⑤描述习惯性动作时,when 从句与主句一般都用一般现在时,且要注意第三人称单数:When she has free time, she swims in the pool.(不能写成 swims ... swim)
⑥易错词形与用法:energy、fruit、sugar、exercise(作“锻炼”讲)、junk food 等多为不可数名词,不加 s;rarely 意为“很少”,本身含否定意味,不能与 not 连用;healthy(形容词)与 health(名词)不要混用。
