We gathered at the river near our neighborhood. Our task was to pick up the garbage that was left by tourists. At first, I felt tired, but when I saw an old man who also joined the cleanup, I got more energy. We sorted the trash into different bins and planted small trees along the riverbank. A little girl asked me why we did this, and I told her that protecting the earth is everyone’s duty. This experience taught me that small actions can make a big difference. Earth Day is not just one day; we should think of every day as Earth Day and do our part to protect our common home. 【译文】 我的地球日行动 去年4月22日，我和同学们参加了社区的地球日活动——我们想为我们的星球做些事情，就像课本里的故事一样。 我们聚集在小区附近的河边，任务是捡起游客留下的垃圾。一开始我觉得很累，但当我看到一位也来参与清理的老爷爷时，我充满了干劲。我们把垃圾分类放进不同的垃圾桶，还在河岸种了小树苗。一个小女孩问我为什么要这么做，我告诉她保护地球是每个人的责任。 这次经历让我明白，微小的行动能带来巨大的改变。地球日不只是某一天，我们应该把每一天都当作地球日，尽自己所能守护我们共同的家园。 亮点词块 1.Earth Day 地球日 2.community activity 社区活动 3.pick up garbage 捡起垃圾 4.sort the trash 分类垃圾 5.riverbank 河岸 6.make a big difference 带来巨大改变 7.common home 共同的家园 高分句子 1.Our task was to pick up the garbage that was left by tourists.（用that引导定语从句修饰事物，贴合单元语法重点） 2.But when I saw an old man who also joined the cleanup, I got more energy.（用who引导定语从句修饰人，细节生动，贴合单元主题） 3.Earth Day is not just one day; we should think of every day as Earth Day and do our part to protect our common home.（升华主题，体现地球日核心理念，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庆祝地球日，请你写一封邮件，分享你的地球日经历及中国学生的环保行动，词数不少于60。 Dear Peter, I’m glad you’re interested in how Chinese students celebrate Earth Day!

Last year, I had a meaningful experience and want to share it with you. On Earth Day, my classmates and I cleaned up the city park. We picked up the trash that was scattered everywhere and posted posters about saving water. Many other students also joined in—some planted trees, some taught kids about pollution. We believe that small acts can protect the earth. Now, more Chinese students use reusable bags and turn off lights when leaving rooms. Earth Day is a chance to act, but we should keep protecting the earth every day. If you come to China, you can join our environmental activities! Yours, Li Hua 【拓展1译文】 亲爱的彼得： 很高兴你对中国学生如何庆祝地球日感兴趣！去年，我有一段很有意义的经历，想和你分享。 地球日那天，我和同学们清理了城市公园。我们捡起四处散落的垃圾，还张贴了节约用水的海报。很多其他学生也参与进来——有的种树，有的给小朋友讲解污染的危害。我们相信，微小的行动能保护地球。现在，越来越多的中国学生使用环保袋，离开房间时会随手关灯。 地球日是行动的契机，但我们应该每天都坚持保护地球。如果你来中国，可以加入我们的环保活动！ 你的， 李华 【拓展2】 请根据以下提示，写一篇短文，论述“日常小事助力地球保护”，词数70左右，开头已给出。 提示 信息 核心观点 地球保护不在于惊天动地的壮举，而在于日常点滴小事，每个人都能成为环保守护者 理由 日常小事易坚持；众人合力效果大；小事积累成习惯 呼吁 从身边小事做起，践行环保，让地球更美好 Protecting the earth doesn’t require great deeds. It lies in small daily actions that everyone can do easily. ________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 【拓展2范文】 Protecting the earth doesn’t require great deeds. It lies in small daily actions that everyone can do easily. We can save water while brushing teeth, use both sides of paper, and pick up trash that we see on the street. These small things, which seem ordinary, can reduce pollution and save resources. When more people join in, small actions will turn into great power. Let’s start with small daily things—turn off lights when leaving, refuse plastic bags, and plant more trees. In this way, we can make our earth greener and healthier. 【拓展2译文】 保护地球不需要惊天动地的壮举，而在于每个人都能轻松做到的日常小事。 我们可以刷牙时节约用水、使用纸的两面、捡起路上看到的垃圾。这些看似平凡的小事，能减少污染、节约资源。当更多人参与进来，微小的行动就会汇聚成巨大的力量。 让我们从日常小事做起——离开时关灯、拒绝塑料袋、多种树。这样一来，我们就能让地球变得更绿色、更健康。 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.环保与地球日相关（单元重点） · 地球日活动：Earth Day 地球日；community activity 社区活动；clean up 清理；pick up garbage 捡起垃圾；sort the trash 分类垃圾；plant trees 种树；post posters 张贴海报；riverbank 河岸 · 定语从句相关：that（指代事物）；who（指代人）；which（指代事物，可省略） · 环保行动：save water 节约用水；save electricity 节约用电；reusable bags 环保袋；reduce pollution 减少污染；save resources 节约资源；common home 共同的家园；make a big difference 带来巨大改变 · 感受与表达：meaningful 有意义的；tired 疲惫的；energetic 充满干劲的；ordinary 平凡的；greener 更绿色的；healthier 更健康的 1. 语法相关（单元重点） · 定语从句（指代事物，that/which）： · The garbage that/which was left by tourists needs to be cleaned.（游客留下的垃圾需要清理。） · The posters that/which we made are about environmental protection.（我们制作的海报是关于环保的。） · 定语从句（指代人，who/that）： · The old man who/that joined the cleanup is very admirable.（参与清理的老爷爷很令人敬佩。） · The students who/that plant trees are protecting the earth.（种树的学生们正在保护地球。） · 定语从句（作宾语，可省略关系代词）： · The trash（that/which）we picked up was sorted into bins.（我们捡起的垃圾被分类放进了垃圾桶。） · The story（that/which）our teacher told us inspired us.（老师给我们讲的故事激励了我们。） 1. 表达类（单元基础） · 逻辑连接：just like 就像；but 但是；when 当……时；and 并且；which 指代前文事物；while 当……时；in this way 这样 · 感悟表达：make a big difference 带来巨大改变；everyone’s duty 每个人的责任；small daily actions 日常小事；great power 巨大力量；common home 共同的家园 二、实用句型积累 1.讲述地球日活动经历（贴合单元核心） · Last...
