一、教学过程
Step 1 Warm-up(Speaking导入)(5~7 min)
【教师活动】T: Good morning, class! Today we'll learn Section B (1a~1f). The topic is about bees. Let's start with a speaking activity. What do you know about bees? Do you know how bees help plants?
【教师活动】T: Look at the pictures and learn these new words. First, pollination — 授粉. When bees fly from one flower to another, they take pollen with them. This action is called pollination. It helps plants grow. New words: pollination (授粉), pollen (花粉), action (行动).
【学生活动】Ss: (学生观看蜜蜂采蜜的图片,学习pollination、pollen、action的读音和含义)
【教师活动】T: Now let's continue. Bees play an important part in the ecosystem. They help plants grow by pollination. We must protect bees and our planet. New phrases: play an important part (在......起重要作用), ecosystem (生态系统), protect (保护), planet (行星/星球).
【学生活动】Ss: (学生学习play an important part、ecosystem、protect、planet的读音和用法)
【教师活动】T: Bees also make honey. In order to store honey, they create honeycombs. And when a bee finds new food, it uses a dance to communicate with other bees. New words: in order to (为了), store (贮存), honeycomb (蜂巢), communicate (交流).
【学生活动】Ss: (学生学习in order to、store、honeycomb、communicate的读音和用法)
【教师活动】T: There's one more important word: lack — 没有;缺乏. For example, if bees lack food, they will die. Now let's check our learning objectives.
【知识点】导入词汇共12个:pollination (授粉)、pollen (花粉)、action (行动)、play an important part (在......起重要作用)、ecosystem (生态系统)、protect (保护)、planet (行星)、in order to (为了)、store (贮存)、honeycomb (蜂巢)、communicate (交流)、lack (没有;缺乏)。注意lack作动词用法——lack sth. (缺乏某物);也作名词——a lack of sth. (缺乏某物)。
【过渡语】好,导入环节的词汇学习完毕。接下来我们将通过标题预测阅读文本内容。
Step 2 Pre-reading(1a 标题预测)(3~4 min)
【教师活动】T: Activity 1a — Read fast and check your guess. Before we read, look at the title: "We Can't Live Without Bees". What do you think the text is about? Discuss with your partner.
【学生活动】Ss: (学生根据标题猜测文本内容:蜜蜂的重要性、蜜蜂与人类的关系、为什么人类离不开蜜蜂等)
【教师活动】T: Now read the text quickly and check your guess. Was your prediction correct? What is the text mainly about?
【学生活动】Ss: (学生快速阅读文本,确认标题预测——文本主要讲述蜜蜂对人类和植物的重要性、蜜蜂的有趣事实以及蜜蜂数量下降的问题)
【知识点】阅读策略——标题预测:通过标题"We Can't Live Without Bees"中的关键词can't live without (离不开)可以预测文本将论述蜜蜂对人类生存的重要作用。预测后通过快速阅读(scanning)验证猜测,培养主动阅读的意识。
【过渡语】标题预测完成。接下来进行精读,划出描述蜜蜂的形容词。
Step 3 While-reading(1b 阅读划形容词)(6~8 min)
【教师活动】T: Activity 1b — Read the text and underline the adjectives. Let's read the text paragraph by paragraph.
【教师活动】T: Read Paragraphs 1 and 2. The title is "We Can't Live Without Bees". Paragraph 1 tells us: Imagine you go to the supermarket, but there are almost no fruits, vegetables, honey, milk, eggs, or chocolate. People, plants, and animals are all connected. We need each other to live, and bees are one of the best examples of this connection.
【教师活动】T: Paragraph 2: Bees are very hard-working animals, and their greatest work is pollination. On one trip, they often visit 50 to 100 flowers. This action helps plants grow. Without their work, about 80 per cent of the plants in the world cannot grow. Many scientists believe that bees are the most important animals on this planet.
【学生活动】Ss: (学生阅读第1-2段,划出形容词:hard-working, greatest, important等)
【教师活动】T: Now Paragraphs 3 and 4. Paragraph 3: Bees are also one of the most interesting animals. They work hard together to make their homes. In order to store honey, they create honeycombs. When a bee finds new food, it uses a dance to communicate. Paragraph 4: Bees play an important part in the ecosystem. However, the number of bees is dropping, and scientists are worried. They need our help.
【学生活动】Ss: (学生阅读第3-4段,划出形容词:interesting, new, important, worried等,其中interesting和amazing前有the most,构成最高级)
【知识点】1b阅读重点形容词归纳:hard-working (勤奋的)、greatest (最大的)、important (重要的)、interesting (有趣的)、new (新的)、worried (担心的)。最高级结构:the most interesting (最有趣的)、the most amazing (最令人惊叹的)、the most important (最重要的)。注意disappointed (失望的)、angry (生气的)、sad (伤心的)是Para 1中描述情绪的形容词。
【提示】阅读策略:划形容词时注意①compound adjective: hard-working (勤劳的)中间有连字符;②superlative adjectives: the most interesting, the most amazing, the most important都用了the most+多音节形容词结构;③emotion adjectives: disappointed/angry/sad出现在Para 1设问句中,描述人类情绪而非蜜蜂特征,不要混淆。
【过渡语】精读和形容词定位完成。接下来用思维导图梳理文章结构。
Step 4 Post-reading(1c 思维导图填空)(6~8 min)
【教师活动】T: Activity 1c — Read again and complete the mind map. The mind map has three main branches: Importance, Interesting Facts, and Problem. Let's fill in each branch.
【教师活动】T: First, the Importance branch. What is bees' greatest work? That's pollination. On one trip, they visit 50 to 100 flowers. This action helps plants grow. Without bees, about 80 per cent of plants cannot grow.
【学生活动】Ss: (学生填写Importance分支:pollination, 50 to 100 flowers, plants grow)
【教师活动】T: Second, the Interesting Facts branch. Bees work hard together to make their homes — honeycombs. They also use a dance to communicate with each other. A bee dances to tell others where and how far away the food is.
【学生活动】Ss: (学生填写Interesting Facts分支:work hard together...honeycombs, use a dance...)
【教师活动】T: Third, the Problem branch. What problem do bees face? The number of bees is dropping. Scientists are worried. Bees need our help.
【学生活动】Ss: (学生填写Problem分支:dropping)
【知识点】思维导图三大分支:①Importance(重要性)—pollination(授粉)、50 to 100 flowers(每次出行访问50-100朵花)、plants grow(帮助植物生长)、80 per cent plants cannot grow(没有蜜蜂约80%植物无法生长);②Interesting Facts(有趣事实)—work hard together to make honeycombs(合作建造蜂巢)、use a dance to communicate(用舞蹈交流食物位置和距离);③Problem(问题)—the number of bees is dropping(蜜蜂数量下降)、scientists are worried(科学家担忧)。
Step 5 Retelling(1d 根据思维导图复述)(4~6 min)
【教师活动】T: Activity 1d — Retell the text according to the mind map. Use the three branches to help you. Start with importance, then interesting facts, and finally the problem. You can use these sentence patterns: Bees are very important because... / Bees are interesting because... / However, the number of bees is...
【学生活动】Ss: (学生根据完整思维导图分三部分复述课文:第一部分讲述蜜蜂通过授粉帮助植物生长,每次出行访问50-100朵花,没有蜜蜂约80%植物无法生长;第二部分讲述蜜蜂合作建造蜂巢储存蜂蜜,用舞蹈交流食物信息;第三部分讲述蜜蜂数量下降,科学家担忧,需要我们帮助)
【提示】复述要点:①用first/second/third或首先/其次/最后等连接词组织语言;②覆盖思维导图三个分支的核心内容;③使用课文原文中的关键表达——pollination, 50 to 100 flowers, honeycombs, communicate, dropping等;④注意时态一致,主要使用一般现在时。
【过渡语】复述完成。接下来进行Think and Share讨论拓展。
Step 6 Think and Share(讨论拓展)(4~6 min)
【教师活动】T: Think and Share — Three questions for you: 1. Can you give another title for this text? 2. What other interesting facts do you know about bees? 3. What's the connection between humans and other insects? Discuss in groups and share.
【学生活动】Ss: (学生小组讨论:①另拟标题如Save Our Bees / The Busy Bees / Bees: Our Tiny Helpers等;②其他蜜蜂趣事如一只蜜蜂一生只能产约1/12茶匙蜂蜜、蜜蜂翅膀每秒扇动约200次等;③人与其他昆虫的联系如蚂蚁翻土、蝴蝶传播花粉)
【教师活动】T: Let's learn more interesting facts about bees. Bees have a strict social structure. The queen bee, worker bees, and drones each have different roles. They can also recognize human faces! And a bee's wings beat about 200 times per second.
【学生活动】Ss: (学生了解蜜蜂的更多趣事:严格的社会分工结构——蜂王/工蜂/雄蜂各司其职、能识别人脸、翅膀每秒扇动约200次)
【教师活动】T: Besides bees, other insects are also important to our planet. Ants help turn over soil, which is good for plant roots. Butterflies spread pollen, just like bees. So people, plants, and insects are all connected.
【学生活动】Ss: (学生了解蚂蚁和蝴蝶的生态作用:蚂蚁帮助翻土促进植物根系生长、蝴蝶像蜜蜂一样传播花粉)
【知识点】拓展知识:①蜜蜂社会结构—queen bee(蜂王)、worker bees(工蜂)、drones(雄蜂)分工明确;②蜜蜂趣事—recognize human faces(识别人脸)、wings beat 200 times/second(翅膀每秒扇动200次)、lifetime honey about 1/12 teaspoon(一只蜜蜂一生产蜜约1/12茶匙);③其他益虫—ants turn over soil(蚂蚁翻土)、butterflies spread pollen(蝴蝶传播花粉);④人与昆虫的共生关系——people, plants, and insects are all connected。
【过渡语】讨论拓展完成。接下来进入1e写作环节,学习保护蜜蜂的四步写作法。
Step 7 Writing(1e 写作四步骤)(10~12 min)
【教师活动】T: Activity 1e — Write a short passage about what we can do to help bees. We will follow four steps.
【教师活动】T: Step 1 — Connect the text and decide the writing direction. Think about the question from the text: "Think about what you can do to protect one of the most amazing animals on earth." Our topic is: What can we do to help bees?
【学生活动】Ss: (学生明确写作方向——根据阅读文本末尾的提问,确定写作主题为What can we do to help bees?)
【教师活动】T: Step 2 — Make an outline and brainstorm. Think of ways to help bees: Be friendly to bees, Plant flowers, Avoid pesticides, Support beekeepers. These are the four main ideas for our writing.
【学生活动】Ss: (学生列提纲,头脑风暴保护蜜蜂的方法:Be friendly to bees不伤害蜜蜂, Plant flowers种植花朵, Avoid pesticides避免使用农药, Support beekeepers支持养蜂人)
【教师活动】T: Step 3 — Expand ideas and add details. Now let's add specific details to each idea. For Plant flowers: plant nectar-rich flowers like lavender, sunflowers, and clover. For Avoid pesticides: pesticides make bees' wings weak and stop them from finding their way home. For Support beekeepers: buying honey directly from beekeepers encourages people to keep working as beekeepers.
【学生活动】Ss: (学生为每个论点添加细节:nectar-rich flowers如lavender、sunflowers、clover;农药使蜜蜂翅膀变弱、迷失方向;直接从养蜂人处购买蜂蜜鼓励养蜂业)
【教师活动】T: Step 4 — Polish your language. Let's look at a possible version. Read carefully and pay attention to the linking words, sentence structures, and vocabulary used.
【学生活动】Ss: (学生阅读范文,学习范文中的写作技巧:first/also/another thing/finally等连接词的运用、具体细节的展开方式、总结性结尾的写法)
【知识点】过程写作法四步骤:①关联文本,确定方向—从阅读文本末尾提问引出写作主题What can we do to help bees?;②列提纲,头脑风暴—四大论点:Be friendly to bees / Plant flowers / Avoid pesticides / Support beekeepers;③拓内容,添细节—为每个论点添加具体细节,如nectar-rich flowers (lavender, sunflowers, clover)、pesticides weaken wings、buying honey encourages beekeepers;④磨表达,范文参考—范文使用了first/also/another thing等连接词,细节丰富具体,结尾Every small thing we do adds up呼应主题。范文全文:There are lots of easy but helpful ways to protect bees. First, we can make our yards or balconies good places for bees. Planting flowers that have lots of sweet nectar—like lavender, sunflowers, and clover—is a great start. These flowers give bees nice food to eat. Also, don't use harmful pesticides in your garden. Pesticides are like poison to bees. They make bees' wings weak and stop them from finding their way back home. Another thing we can do is help local beekeepers. If we buy honey directly from them, we get pure, yummy honey. And it also encourages people to keep working as beekeepers. Every small thing we do adds up. It helps bees live and grow better.
【过渡语】写作四步骤学习完毕。接下来分享写作并进行同伴评价。
Step 8 Sharing & Evaluation(1f 分享与评价)(5~7 min)
【教师活动】T: Activity 1f — Let's share! Now share your writing in groups. Read your partner's writing carefully and give feedback using the evaluation chart.
【学生活动】Ss: (学生小组内互相分享各自的写作,朗读自己的作品,同伴认真倾听)
【教师活动】T: Here is the evaluation chart. It has four parts: Structure (3 points), Content (4 points), Language (2 points), and Emotion (1 point). Total: 10 points. Please evaluate your partner's writing honestly.
【学生活动】Ss: (学生根据评价表对同伴的写作进行评价:结构3分(有开头/主体/结尾,使用连接词)、内容4分(论点明确、细节具体、建议合理)、语言2分(语法正确、词汇恰当、拼写无误)、情感1分(表达对蜜蜂保护的关注和责任感))
【提示】评价要点:①Structure(结构)3分—有清晰的开头、主体、结尾,使用连接词(first/also/another/finally);②Content(内容)4分—论点明确(保护蜜蜂的方法)、细节具体(如花朵种类、农药危害)、建议合理可行;③Language(语言)2分—语法正确、词汇恰当(使用本课核心词汇如pollination/protect/pesticides)、拼写无误;④Emotion(情感)1分—表达对蜜蜂保护的真诚关注和责任感。
Step 9 Think Deeply(深度思考)(4~5 min)
【教师活动】T: Think deeply — How do you understand the connection between people, plants, and animals? This is a big question. Let's think about it from the text and from our own lives.
【学生活动】Ss: (学生思考人与动植物的关联:蜜蜂通过授粉帮助植物生长,植物为人类提供食物和氧气,动物维持生态平衡——三者互相依存、缺一不可)
【教师活动】T: Let's look at a sample dialogue. A says: People and nature are connected. When we protect nature, we protect ourselves. B says: Last summer, I visited a small town. It had large trees, beautiful birds, and many tourists. People there lived happily because the environment was good. This shows that people, plants, and animals depend on each other.
【学生活动】Ss: (学生学习示例对话,理解人与自然和谐共处的理念:保护自然就是保护人类自己,良好的生态环境是人类幸福生活的基础)
【知识点】深度思考核心观点:①人与自然相互依存—people, plants, and animals are all connected,三者构成完整的生态链;②蜜蜂是人与自然连接的桥梁—通过授粉连接植物与人类的食物供应;③保护动物就是保护人类自己—When we protect nature, we protect ourselves;④生态平衡影响人类生活—good environment = happy life,破坏生态最终损害人类自身利益。参考表达:depend on each other / live in harmony / protect nature / break the balance。
【知识拓展】蜜蜂的生态重要性数据:全球约80%的开花植物依赖蜜蜂授粉;蜜蜂每秒翅膀扇动约200次;一只蜜蜂一生只能产约1/12茶匙蜂蜜;全球约有2万种蜜蜂。这些数据可用于写作和口语表达中增强说服力。
Step 10 Summary & Homework(2~3 min)
【教师活动】T: Let's summarize what we learned today. First, we learned new words about bees and the ecosystem. Second, we read the text "We Can't Live Without Bees" and used a mind map to understand the importance, interesting facts and problems of bees. Third, we learned how to write about protecting bees using four steps: connect, outline, expand, and polish. Finally, we shared our writing and evaluated each other's work.
【学生活动】Ss: (学生回顾本课所学:核心词汇、阅读文本理解、思维导图梳理、过程写作法、同伴评价)
【教师活动】T: Homework: 1. Revise and improve your writing from Activity 1e. Check your spelling, grammar, and linking words. 2. Observe the plants and animals around you. Write down how they are connected in English. 3. Preview the next section.
【知识点】本课总结:①核心词汇12个—pollination/pollen/action/play an important part/ecosystem/protect/planet/in order to/store/honeycomb/communicate/lack;②阅读文本三层次—重要性(pollination/50-100 flowers/80% plants)、有趣事实(honeycombs/dance communication)、问题(dropping/worried);③思维导图三分支—Importance/Interesting Facts/Problem;④过程写作四步骤—关联文本→列提纲→拓内容→磨表达;⑤评价表四维度—Structure(3分)/Content(4分)/Language(2分)/Emotion(1分);⑥深度思考核心观点—人与自然相互依存。
【过渡语】本节课我们通过阅读了解了蜜蜂对人类和植物的重要性,学习了用思维导图梳理文章结构,掌握了过程写作法的四个步骤。请大家认真完成作业,下节课再见!
