Unit 4　Amazing Plants and Animals Section B(1a—1f) 教学设计 课　　题 How are plants and animals connected with us?（Section B 1a—1f） 课　　型 阅读课（Reading & Writing） 课　　时 第4课时（45分钟） 核心素养目标 语言能力 能读懂课文并划出描述蜜蜂的形容词；能用课文信息补全思维导图；能回答 1d 问题并续写一段关于蜜蜂的话；能用英语举例说明人与动植物的联系。 学习能力 能借助思维导图梳理说明文的结构；能复用课文句式（Bees are…, and… / For example…）完成续写。 思维品质 能梳理"传粉—植物生长—人类生活"的因果链；能针对蜜蜂数量下降提出可行的保护建议。 文化意识 认识生态系统中万物互联的道理，形成保护蜜蜂、爱护自然的责任感。 教学重难点 教学难点：pollination、honeycomb、ecosystem 等术语的理解；续写段落中课文句式的迁移；因果链的条理表达。 教学重点：课文的理解与结构梳理（importance / interesting facts / problem）；描述蜜蜂的形容词；人与动植物联系的举例表达。 语篇研读 【What】本课围绕说明文 We Can’t Live Without Bees 展开。1a 看标题与插图预测内容；1b 阅读并划出作者描述蜜蜂的形容词（hard-working, one of the most important animals, one of the most interesting animals, amazing）；1c 用课文信息补全蜜蜂思维导图（importance—greatest work: pollination，visit 50 to 100 flowers on one trip，help plants grow，约 80% 的植物离不开它们；interesting facts—work hard together to make their homes，create honeycombs to store honey，用舞蹈告诉同伴食物的方位与距离；problem—the number of bees is dropping，scientists are worried）；1d 讨论三个问题（另拟标题、蜜蜂的其他趣事、蚂蚁蝴蝶等昆虫与人的联系）；1e 以作者身份为课文再写一段；1f 借助示例对话谈论动植物与人之间的联系。 【Why】文章以"超市里几乎没有水果蔬菜蜂蜜"的假设开场，直观呈现人与动植物的相互依存；蜜蜂作为 best example 把"传粉—生态—保护"的逻辑链条讲清，落实单元"探究动植物为何重要"的目标与生态保护育人价值。 【How】按"预测→默读划词→图梳→问题讨论→续写一段→结对分享"推进；阅读训练找读与依据文本作答；1e 用课文句式做支架的微写作；1f 引用课文语言联系生活举例。 学情分析 学生能读懂记叙文，说明文的段落主旨与逻辑链（现象—原因—意义—问题）需要引导；pollination、honeycomb、ecosystem 等术语是理解障碍；续写段落时易脱离课文句式自由发挥，需要支架。 教学过程 教学环节 教师活动 学生活动 Step 1 情境导入 (5’) ①组织闭眼想象：Imagine you’re walking through a lush forest. What kinds of plants and animals can you picture?，请学生说出想到的动植物及形容词； ②创设问题情境：Imagine you go to the supermarket, but there are almost no fruits, vegetables, honey, milk, eggs, or chocolate. How would you feel?； ③引出课题：蜜蜂是人与动植物相互依存的 best example。 ①闭眼想象，说出动植物与描述词； ②表达自己的感受（Disappointed. Angry. Sad.）； ③初识课题，产生阅读期待。 Step 2 Work on 1a—1b 预测与初读 (9’) ①组织看标题与插图预测：What is the text about?； ②布置默读任务：Read the text and underline the adjectives the writer uses to describe bees.； ③出示课文全文供核对理解：We Can’t Live Without Bees——Imagine you go to the supermarket in your area, but there are almost no fruits, vegetables, honey, milk, eggs, or chocolate. How would you feel? Disappointed? Angry? Sad? At this moment you realize people, plants, and animals are all connected. We need each other to live, and bees are one of the best examples of this connection.　Bees are very hard-working animals, and their greatest work is pollination. On one trip, they often visit 50 to 100 flowers. As they fly from one flower to another, they take pollen with them. This action helps plants grow. In fact, without their work, about 80 per cent of the plants in the world cannot grow. For this reason, many scientists believe that bees are the most important animals on this planet.　Bees are also one of the most interesting animals in the world. For example, they work hard together to make their homes. In order to store honey, they create honeycombs. Another interesting thing about bees is how they communicate. When a bee finds new food, it uses a dance to tell the others where and how far away the food is.　Bees play an important part in the ecosystem of our planet. However, the number of bees is dropping, and scientists are worried. Bees need our help, and there is a lot we can do. Think about what you can do to protect one of the most amazing animals on earth.； ④核对所划形容词（hard-working, the most important, one of the most interesting, amazing）。 ①看图预测文章内容； ②默读课文，划出描述蜜蜂的形容词； ③核对全文与答案，理解 pollination 等术语。 Step 3 Work on 1c 图梳结构 (8’) ①出示思维导图框架（Bees：importance / interesting facts / problem），组织再读补全（参考答案：importance—their greatest work is pollination；visit 50 to 100 flowers on one trip；help plants grow（about 80 per cent of plants cannot grow without them）；scientists believe bees are the most important animals；interesting facts—work hard together to make their homes；create honeycombs to store honey；use a dance to tell others where and how far away the food is；problem—the number of bees is dropping and scientists are worried）； ②请学生依据导图用自己的话概括蜜蜂的重要性。 ①再读课文补全思维导图； ②核对订正； ③用连贯的话概括蜜蜂的重要性。 Step 4 Work on 1d 问题讨论 (8’) ①出示三个问题组织结对讨论：1. Can you give another title for the text?　2. What other interesting facts do you know about bees?　3. What do you know about the connection between humans and other insects, such as ants and butterflies?； ②组织全班分享，鼓励相互补充； ③教师点评：拟题要抓住主旨，举例要有依据。 ①结对讨论三个问题； ②全班分享并互相补充； ③记录拟题与举例的方法。 Step 5 Work on 1e 续写段落 (9’) ①出示写作任务：Imagine you are the writer. Write one more paragraph about bees and add it to the text.； ②提示从蜜蜂的习性或生态作用再选一个角度（如 bee products：honey, beeswax；bees and flowers 的相互适应），出示句式支架：Bees are… / For example… / Another interesting thing about bees is… / That’s why…； ③组织写作与同伴互评，选 1—2 篇朗读展示。 ①确定续写角度； ②借句式支架写一段话； ③互评修改并展示。 Step 6 Work on 1f 结对分享 (4’) ①出示示例对话：A: We all know people and nature are connected. But can you give me an example of how they are connected?　B: Sure. I visited a small town in Guangdong once. There are many large trees in the town. They are home to many birds. A lot of tourists come to see the trees and the birds…； ②组织结对模仿举例分享人与动植物的联系。 ①读示例对话，明确表达结构； ②结对举例分享，互相追问。 Step 7 归纳总结 布置作业 (2’) ①依托板书梳理课文三块结构与因果链； ②发放自评卡，组织勾选达成项； ③布置分层作业并说明要求。 ①跟随板书口头归纳； ②在自评卡上勾选达成项； ③记录分层作业要求。 板书设计 Unit 4　Amazing Plants and Animals — Section B (1a—1f) 标题：We Can’t Live Without Bees importance：pollination→help plants grow（80%）→most important facts：honeycombs　communicate by dance problem：number dropping→need our help 作业设计 本课作业围绕蜜蜂话题的巩固与拓展阅读设计。 【基础·必做】①朗读课文并背诵 1c 思维导图要点；②把 1e 续写段修改誊写一遍。 【提升·选做】查阅资料再写两条关于蜜蜂的趣事，用上 one of the most… 结构。 【拓展·挑战】比较蜜蜂与蚂蚁的群居生活，写 5 句短文说明两者的相同与不同。 巩固检测（当堂完成） 一、根据课文内容判断正（T）误（F）。 1. Bees often visit 50 to 100 flowers on one trip. 2. About 80 per cent of the plants in the world cannot grow without bees’ work. 3. Bees use a song to tell the others where the food is. 4.
