To reduce waste, I started turning off the water while brushing teeth and using cloth bags for shopping. For reuse, I collected used paper to draw on both sides and refilled my shampoo bottle. I also sorted plastic bottles and newspapers into recycling bins with my family. A neighbor saw us and joined in, which made me very proud. I found that reusing things is much easier than I thought, and recycling makes our community far cleaner. This experience teaches me that protecting the earth doesn’t need great deeds. By following the 3R principle, we can save resources and make life better. I will keep practicing 3R in daily life. 【译文】 我的3R环保行动 上个月，我们班发起了“3R环保行动”——我明白了，就像课本中所说，微小的行动能带来巨大的改变。 为了减量，我开始刷牙时关水，购物时使用布袋；为了再利用，我收集废纸正反面画画，给洗发水瓶 refill；我还和家人一起将塑料瓶和报纸分类放入回收箱。一位邻居看到后也加入了我们，这让我非常自豪。我发现，再利用比我想象的容易得多，而回收让我们的社区干净了不少。 这次经历让我明白，保护地球不需要惊天动地的壮举。遵循3R原则，我们就能节约资源，让生活更美好。我会在日常生活中一直践行3R。 亮点词块 1.3R Environmental Campaign 3R环保行动 2.turn off the water 关水 3.cloth bags 布袋 4.refill the shampoo bottle 给洗发水瓶 refill 5.sort into recycling bins 分类放入回收箱 6.save resources 节约资源 7.follow the 3R principle 遵循3R原则 高分句子 1.I found that reusing things is much easier than I thought, and recycling makes our community far cleaner.（运用much/far修饰比较级，贴合单元语法重点） 2.To reduce waste, I started turning off the water while brushing teeth and using cloth bags for shopping.（细节具体，呼应3R原则，贴合单元主题） 3.By following the 3R principle, we can save resources and make life better.（升华主题，体现3R原则的核心价值，贴合单元内涵） 【拓展1】 你的外国笔友Peter想了解中国学生如何践行环保，请你写一封邮件，分享你的3R行动及身边的环保现象，词数不少于60。 Dear Peter, I’m glad you’re interested in environmental protection in China! Recently, I’ve been practicing the 3R principle and want to share my experience with you. ________________________________________________________________________________________________________________________________________________________________________________________________________________________________ Yours, Li Hua 【拓展1范文】 Dear Peter, I’m glad you’re interested in environmental protection in China! Recently, I’ve been practicing the 3R principle and want to share my experience with you. I reduce waste by using both sides of paper and refusing plastic bags. I reuse old boxes to store books and recycle cans with my classmates. Many Chinese students are doing the same — our school has separate recycling bins, and more families use refillable products. I find that living an eco-friendly life is even simpler than expected, and it makes the environment a lot better. If you come to China, I’ll show you how we practice 3R. Let’s work together to protect the earth! Yours, Li Hua 【拓展1译文】 亲爱的彼得： 很高兴你对中国的环保感兴趣！最近，我一直在践行3R原则，想和你分享我的经历。 我通过双面用纸、拒绝塑料袋来减少浪费；用旧盒子装书，和同学一起回收易拉罐。很多中国学生也在这么做——我们学校有分类回收箱，越来越多家庭使用可重复填充的用品。我发现，环保生活比想象中简单得多，而且能让环境变好很多。 如果你来中国，我带你看看我们是如何践行3R的。让我们一起保护地球！ 你的， 李华 【拓展2】 请根据以下提示，写一篇短文，论述“3R原则让地球更可持续”，词数70左右，开头已给出。 提示 信息 核心观点 3R原则（减量、再利用、回收）是节约资源、减少污染的关键，让地球更具可持续性 理由 减量减少资源消耗；再利用延长物品寿命；回收转化废物为资源 呼吁 人人践行3R，让环保成为生活习惯 The 3R principle — Reduce, Reuse, Recycle — is crucial for a sustainable earth. It helps us save resources and cut down pollution effectively. ________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 【拓展2范文】 The 3R principle — Reduce, Reuse, Recycle — is crucial for a sustainable earth. It helps us save resources and cut down pollution effectively. Reducing waste means using less energy; reusing things makes them last longer, which is far better than throwing them away. Recycling turns waste into new materials, making resources much more valuable. Without 3R, our planet will face worse shortages. We should practice 3R in daily life: refuse unnecessary products, reuse old items, and sort trash. Small efforts will make the earth a greener home for everyone. 【拓展2译文】 3R原则——减量、再利用、回收——对地球的可持续发展至关重要，它能有效帮助我们节约资源、减少污染。 减量意味着消耗更少能源；再利用让物品使用寿命更长，这比扔掉它们好得多；回收将废物转化为新材料，让资源更具价值。没有3R，我们的星球将面临更严重的资源短缺。 我们应该在日常生活中践行3R：拒绝不必要的产品、重复使用旧物品、给垃圾分类。微小的努力，终将为每个人打造一个更绿色的地球家园。 本话题作文的一些实用短语与句型积累 一、核心主题词汇 1.3R与环保相关（单元重点） · 3R行动：reduce waste 减少浪费；reuse old items 重复使用旧物品；recycle trash 回收垃圾；sort into recycling bins 分类放入回收箱；cloth bags 布袋；refillable products 可重复填充的产品；used paper 废纸；plastic bottles 塑料瓶 · 比较级修饰词：even 甚至；far 得多；much 非常；a lot 很，非常 · 环保表达：save resources 节约资源；cut down pollution 减少污染；eco-friendly life 环保生活；sustainable earth 可持续发展的地球；waste materials 废料；new materials 新材料 · 感受与动作：be proud 自豪；join in 加入；launch a campaign 发起行动；refuse 拒绝；store 储存；practice 践行 1. 语法相关（单元重点） · 修饰比较级的副词（even/far/much/a lot）： · Reusing is much easier than I thought.（再利用比我想象的容易得多。） · Recycling makes the community far cleaner.（回收让社区干净了不少。） · Eco-friendly life is even simpler than expected.（环保生活比预期的更简单。） · It makes the environment a lot better.（它让环境变好很多。） · 比较级句型： · A is + 修饰词 + 比较级 + than B.（A比B……得多） · The + 比较级 + 主语 + 谓语，the + 比较级 + 主语 + 谓语.（越……越……） 1. 表达类（单元基础） · 逻辑连接：just like 就像；by 通过；and 并且；which 指代前文；without 没有；if 如果；so 因此 · 感悟表达：make a big difference 带来巨大改变；crucial for 对……至关重要；cut down pollution 减少污染；sustainable earth 可持续发展的地球；small efforts 微小的努力 二、实用句型积累 1.讲述3R践行经历（贴合单元核心） · Last... we launched a... — I learned that... 去年……我们发起了……——我明白了……，例：Last week we launched a recycling activity — I learned that trash can be turned into treasures. · To reduce..., I...
