We've learned many amazing plants and animals in this unit. Can you name some of them? What makes them amazing? 教师用英语提问，引导学生回顾本单元学过的动植物词汇，激活学生已有知识储备。 【学生活动】Ss: We learned about the blue whale - it's the largest animal in the world. / The cheetah is the fastest land animal. / Bamboo is one of the most useful plants. 学生用英语回答，激活已有知识储备，复习最高级用法。 【教师活动】T: Excellent! You remembered so many amazing plants and animals. Today we are going to do a project - make a poster about a plant or an animal you like, and present it in class. 教师引出本节课项目任务，激发学生兴趣。 【学生活动】Ss: 学生明确本节课项目任务：小组合作制作一张自己喜欢的动植物海报，并在班级内进行展示介绍。学生对任务充满期待，准备参与到项目活动中。 【过渡语】There are so many amazing animals and plants in our world. Let's think about which one impresses you most, and start our project journey! 课堂导入：讨论世界上令人印象深刻的动植物 Step 2 Presentation（知识呈现：4a选定主题→4b收集信息）（10~15 min） 4a 选定主题与创作海报标题（5~7 min） 【教师活动】T: Look at Activity 4a. First, choose a plant or an animal that interests your group. Then think about its special features. For example, cheetah - the fastest, bamboo - the most useful. Finally, choose or create a title for your poster. What title can you create? 教师展示4a任务要求，用PPT中的例子说明如何选择主题和创作标题，鼓励学生发挥创意。 【学生活动】Ss: 学生以小组为单位讨论，选定感兴趣的动植物并创作海报标题。Group 1: We choose the panda. Title - 'The Cutest Symbol of China'. Group 2: We choose the cheetah. Title - 'The Fastest Runner on Earth'. Group 3: We choose the blue whale. Title - 'The Gentle Giant of the Ocean'. 各小组汇报选定主题和海报标题，全班进行简要点评。 【教师活动】T: Great titles, everyone! Let me give you some feedback. Group 1, your title 'The Cutest Symbol of China' is perfect because it shows both the feature and cultural meaning. Group 2, 'The Fastest Runner on Earth' clearly tells us the superlative feature. Group 3, 'The Gentle Giant of the Ocean' uses a nice contrast - gentle but giant. A good title should be short, clear, and attractive. 教师逐一点评各组标题，强调好标题的三大标准：简洁、清晰、有吸引力，帮助学生在后续创作中优化标题设计。 【知识点】choose v. 选择。interest v. 使感兴趣。feature n. 特征；特点。title n. 标题。海报标题要简洁醒目，能体现该动植物的突出特点。创意标题可以吸引更多观众的关注。 【知识拓展】动植物文化意义 许多动植物在不同文化中具有特殊意义。 熊猫(panda)是中国文化的象征，代表和平与友好。 蓝鲸(blue whale)是地球上最大的动物，象征着大自然的神奇力量。 竹子(bamboo)在中国文化中代表坚韧不拔的品格。 选择动植物时，可以考虑其文化意义，让海报更有深度。 【过渡语】Good choices! Now that you have your title, let's collect more information about your plant or animal. Let's move to Activity 4b. 项目任务介绍：制作动植物海报的步骤与要求 4b 收集图片与信息（5~8 min） 【教师活动】T: Activity 4b. Collect pictures and find out information about the plant or animal you chose. You need to answer four questions: What is its name? Where does it live or grow? Why did you choose it? What are some interesting facts about it? Let's look at the panda example together. 教师展示信息收集框架，以熊猫为例进行示范，引导学生分工合作。 【学生活动】Ss: 学生小组合作，根据四个问题收集信息。以panda为例：Its name is panda / giant panda. It lives in the bamboo forests of central China, mainly in Sichuan, Shaanxi, and Gansu provinces. We chose it because it is not only cute, but also a symbol of China. An interesting fact is that more than 90% of pandas' diet is bamboo, and they spend 10-16 hours daily eating. 学生用英语整理信息，填写到信息卡中。 【理解要点】信息收集四问框架 制作动植物海报时，围绕四个核心问题收集信息： ① What is its name? - 名称是什么？ ② Where does it live / grow? - 它生活/生长在哪里？ ③ Why did you choose it? - 为什么选择它？ ④ What are some interesting facts about it? - 有哪些趣味事实？ 回答这四个问题，就能完整描述一种动植物。 【知识点】collect v. 收集。information n. 信息（不可数名词）。live v. 生活；居住。grow v. 生长。interesting facts 趣味事实。注意：information为不可数名词，不能说'an information'，应说'some information'或'a piece of information'。 【易错提示】information不可数名词用法 information是不可数名词，没有复数形式。 ❌ 错误：an information / many informations ✅ 正确：some information / a piece of information / much information 类似不可数名词还有：advice, news, knowledge, furniture等。 信息收集任务：围绕四个核心问题收集动植物信息 信息收集示例：以熊猫为例的信息整理 【过渡语】Great! You've collected enough information. Now let's make your poster and prepare for the presentation. Remember, a good poster needs clear information and attractive design. Step 3 Practice（操练巩固：4c展示准备）（15~20 min） 3a 确定展示分工与梳理核心内容（6~8 min） 【教师活动】T: Activity 4c. Before you present, let's organize your team. In each group, you need three roles: a main speaker, assistants, and a time keeper. The main speaker explains the core content for about 70% of the time. The assistants point to details and add one or two interesting facts. The time keeper makes sure your presentation is 3-5 minutes. 教师展示展示分工要求，引导学生明确各自职责，确保每位学生都有参与机会。 【学生活动】Ss: 学生小组内明确分工。Main speaker: I'll introduce the panda's name, home, and why we chose it. Assistant: I'll point to the pictures and add interesting facts. Time keeper: I'll watch the time and remind the team when we have one minute left. 各小组汇报分工方案，教师给予反馈建议。 【教师活动】T: Now let's organize your content in a logical order. Start with an introduction to your topic. Then give the key information using 'First... / Then... / Finally...'. Finally, highlight one or two amazing facts. Remember the 'Three Don'ts': don't read from notes, don't block the poster, and don't speak too quietly. 教师讲解内容组织逻辑和展示注意事项，强调衔接词的使用。 【学生活动】Ss: 学生按照逻辑顺序梳理展示内容。开场引入：Hello everyone! Today we'll introduce our poster - The Cutest Symbol of China. 核心信息：First, the panda's name and home. Then, why we chose it. Finally, interesting facts. 亮点突出：The most interesting thing is that pandas spend 10-16 hours eating bamboo every day! 学生练习用衔接词组织语言，使表达更连贯。 【知识点】role n. 角色。core n. 核心。logical adj. 逻辑的。highlight v. 突出；强调。衔接词 First... / Then... / Finally... 用于按逻辑顺序组织展示内容，使表达更清晰连贯。展示时要注意与观众的眼神交流，避免低头念稿。 【教师活动】T: Now let's talk about poster design. A good poster needs both good content and good layout. Put your title at the top in large letters. Use pictures in the middle - they should be clear and colourful. Put key information in short sentences around the pictures. Use different colours for different parts, but don't use too many colours - three or four is enough. Remember: less text, more pictures, clear layout. 教师讲解海报视觉设计原则，展示优秀海报范例，引导学生将信息收集内容与视觉设计结合。 【学生活动】Ss: 学生听取海报设计指导，在小组内讨论海报布局方案。We will put the title 'The Cutest Symbol of China' at the top with a big panda picture in the centre. Around the picture, we'll write short sentences about where it lives and why we chose it. We'll use black, white and green colours. 各小组确定海报版面设计，分配绘图和文字任务。 展示准备：小组分工与内容组织指导 【过渡语】Well organized! Now let's learn some useful expressions for your presentation. Good language and confident body language will make your show excellent! 3b 展示范例语言与展示技巧（6~8 min） 【教师活动】T: Look at this example. You can present like this: 'Hello everyone! Today we'll introduce our poster - The X X X. Its name is ... It grows / lives in ... We chose it because ... The most interesting thing about it is ... This picture shows ... Thank you for listening! Remember - protect ... , and protect our nature.' 教师带领学生朗读范例，分析语言结构，强调每个句型的功能。 【学生活动】Ss: 学生跟读范例展示语，替换关键词进行仿说。Hello everyone! Today we'll introduce our poster - The Fastest Runner on Earth. Its name is cheetah. It lives in the grasslands of Africa. We chose it because it can run up to 110 kilometres per hour. The most interesting thing about it is that it can go from 0 to 100 km/h in just three seconds. Thank you for listening! Remember - protect wild animals, and protect our nature. 学生仿照范例组织自己的展示语言，进行小组内练习。 【重点强调】展示范例语言模板 展示时可按以下模板组织语言： Hello everyone! Today we'll introduce our poster - [标题]. Its name is [名称]. It grows / lives in [生存环境]. We chose it because [选择理由]. The most interesting thing about it is [趣味事实]. This picture shows [图片说明]. Thank you for listening! Remember - protect [保护对象], and protect our nature. 掌握这个模板，就能完成一次完整的英文展示。 【教师活动】T: Besides good language, you also need good presentation skills. First, catch the audience's attention with a question or interaction at the beginning. Second, use pictures and simple expressions. Third, show confidence and enthusiasm with your body language and tone. Finally, control your time - 3 to 5 minutes is the golden length. Let's practice together! 教师讲解展示技巧四要点，并进行示范演示。 【学生活动】Ss: 学生记录展示技巧要点：开场吸睛（用互动/疑问拉近距离）、内容讲解（图文结合+简洁表达）、仪态与语气（传递自信与热情）、时间把控（3-5分钟黄金时长）。学生模拟练习开场互动和手势配合，如指向海报、模拟动物动作等。 【知识点】audience n. 观众；听众。attention n. 注意力。interaction n. 互动。confidence n. 自信。enthusiasm n. 热情。body language 肢体语言。golden length 黄金时长。展示时眼神要面向观众，适当使用手势指向海报内容，声音要洪亮清晰，站姿要自然大方。 【判断技巧】展示时间把控方法 建议展示时间分配： 开场引入：30秒-1分钟 核心信息讲解：2-3分钟 趣味事实亮点：30秒-1分钟 结尾呼吁：15-30秒 总计：3-5分钟 提醒人应在剩余1分钟时给出信号，确保不超时。 展示技巧：语言表达与肢体语言指导 【过渡语】You've prepared well. Now it's time to present your posters! Let's welcome each group to the front and share your amazing plants or animals with the class. Step 4 Production（拓展输出：4c海报展示+4d小组互评）（5~8 min） 【教师活动】T: Before we start, let me remind you of some presentation manners. First, walk to the front confidently and place your poster where everyone can see it. Second, stand beside your poster, not in front of it. Third, speak loudly enough so that everyone in the last row can hear you. Fourth, look at your audience, not just at your poster. Finally, when you finish, say 'Thank you' and walk back to your seat quietly. 教师强调展示礼仪，帮助学生建立自信，确保展示过程有序进行。 【学生活动】Ss: 学生听取展示礼仪提醒，在小组内做最后准备。Main speaker practices walking to the front confidently. Assistant checks if the poster is easy to see from the back. Time keeper sets a timer for 4 minutes. 各小组做展示前的最后检查，确保语言、仪态、时间均准备就绪。 【教师活动】T: Now each group will present your poster in class. Remember to use the useful expressions and presentation skills we just learned. Speak clearly, make eye contact with your audience, and don't forget to point to your poster. After each presentation, other groups will give feedback from four dimensions: information accuracy, language fluency, cultural depth, and creative thinking. Let's start with Group 1! 教师组织各小组依次上台展示，计时并记录表现，营造积极的展示氛围。 【学生活动】Ss: Group 1 presents their poster about pandas. Hello everyone! Today we'll introduce our poster - The Cutest Symbol of China. Its name is panda. It lives in the bamboo forests of central China. We chose it because it is not only cute, but also a symbol of China. The most interesting thing about it is that more than 90% of pandas' diet is bamboo. Thank you for listening! Remember - protect pandas, and protect our nature. 其他小组认真聆听，从四个维度进行评价并记录评分。 【知识点】present v. 展示；介绍。feedback n. 反馈。accuracy n. 准确性。fluency n. 流畅度。creative thinking 创新思维。小组互评维度：信息准确性（information accuracy）、语言流畅度（language fluency）、文化挖掘度（cultural depth）、思维创新性（creative thinking）。 【教师活动】T: Great job, Group 1! Now let's do Activity 4d - group evaluation. Please vote for the best group in each category: 'Science Expert' for the most accurate information, 'Language Star' for the best English, 'Culture Ambassador' for the deepest cultural understanding, and 'Creative Maker' for the most innovative ideas. You can discuss in your groups first. 教师引导学生进行小组互评，选出各类奖项，鼓励学生用英语表达评价意见。 【学生活动】Ss: 学生根据评价标准投票并说明理由。We think Group 1 is the 'Culture Ambassador' because they explained the panda as a symbol of China very well. Group 2 is the 'Science Expert' because they gave many accurate facts about the cheetah. Group 3 is the 'Creative Maker' because their poster design was very attractive. 学生用英语表达评价意见，锻炼批判性思维和口语表达能力。 小组互评：多维度评价标准与评选奖项 【过渡语】All groups did an amazing job! Now let's reflect on what we've learned in this unit and think about how we are connected with plants and animals. Step 5 Summary & Homework（单元反思与作业布置）（2~3 min） 【教师活动】T: Let's do the Reflecting activity. Think about these questions: What amazing plants and animals did you learn about in the unit? When do you use the superlative forms of adjectives and adverbs? Can you describe some amazing plants or animals in the world? How are we connected with plants and animals? I'll give you two minutes to think, then share with your partner. 教师引导学生回顾单元核心内容，组织同伴交流活动。 【学生活动】Ss: 学生回顾并回答。We learned about the blue whale, bee, frog, cheetah, bamboo, redwood tree, ginkgo tree, and moss. We use superlative forms when we compare three or more people, things, or actions and show which one is the 'most' or 'least' in a certain way. We have a very close connection with plants and animals - they give us oxygen, food, and materials, and we need to protect them. 学生用英语总结单元要点，巩固所学知识。 【知识点】superlative forms 最高级形式。当比较三者或三者以上的人、事物或行为，表示某一方面'最……'或'最不……'时，使用形容词或副词的最高级形式。connection n. 联系；连接。ecosystem n. 生态系统。人类与动植物的关系：植物提供氧气和食物，动物帮助授粉和提供食物，我们需要保护它们以维持生态平衡。 单元回顾：What makes plants and animals amazing? 反思活动：回顾单元核心问题与学习收获 【教师活动】T: For homework, please complete two tasks. First, work in groups to make a 'Protect Plants and Animals' poster in English, adding cultural appeals and action calls, like 'Protect pandas - guard China's cultural treasure!' Second, review what you've learned in this unit based on the reflection results, and fill in any gaps. Next class, we'll share your protection posters. 教师布置课后作业，明确任务要求和下节课展示安排。 【学生活动】Ss: 学生记录作业内容：①小组合作制作'动植物保护倡议海报'，融入文化呼吁与行动号召；②根据单元反思结果复习本单元知识，查漏补缺。学生明确课后任务，为下节课做好准备。 课后作业：保护动植物倡议海报制作与单元复习 二、板书设计（三栏式） Key Vocabulary （重点词汇） Grammar Focus （语法聚焦） Useful Expressions （重点句式） 1. feature n. 特征 2. collect v. 收集 3. information n. 信息 4. connection n. 联系 5. audience n. 观众 Superlative Forms 最高级 结构：the + adj./adv. + -est the most + adj./adv. 例：the fastest, the most useful the largest, the cutest 1.
