He does small but meaningful things to protect the environment, and his actions show that everyone can make a difference. Every morning, Gary starts his day by taking a shower instead of a bath to save water. He rides a bike to school instead of taking a car, which helps reduce carbon dioxide emissions. At school, he always turns off the tap after washing his hands and switches off the lights when leaving the classroom. When doing homework, he uses both sides of the paper, never wasting a single sheet. Gary’s lifestyle is different from many people who ignore environmental problems. He often says that protecting the environment is not the same as doing a big project—it’s about sticking to small habits. His efforts inspire his classmates to join in environmental protection. Gary proves that being a green consumer and living a low-carbon life is easy and meaningful. 【译文】 加里·格林：我们身边的环保英雄 加里·格林是一位真正的环保卫士，他的日常生活为我们树立了完美的榜样。他做着看似微小却意义重大的事来保护环境，他的行动表明每个人都能产生影响。 每天早上，加里用淋浴代替泡澡来节约用水。他骑自行车上学而不是坐车，这有助于减少二氧化碳排放。在学校，他洗完手总会关掉水龙头，离开教室时会随手关灯。做作业时，他会双面使用纸张，从不浪费一页纸。 加里的生活方式与许多忽视环境问题的人不同。他常说，保护环境和做大型项目不一样——关键在于坚持微小的习惯。他的努力激励同学们加入环保行列。加里证明，成为环保消费者、过低碳生活既简单又有意义。 亮点词块 1.environmental protector 环保卫士 2.set a perfect example 树立完美榜样 3.carbon dioxide emissions 二氧化碳排放 4.switch off the lights 关灯 5.use both sides of the paper 双面用纸 6.green consumer 环保消费者 7.low-carbon life 低碳生活 8.make a difference 产生影响 高分句子 1.Gary Green is a true environmental protector whose daily life sets a perfect example for us.（运用定语从句介绍人物身份，开篇点题，贴合单元话题核心） 2.Gary’s lifestyle is different from many people who ignore environmental problems.（运用different from结构对比生活方式，贴合单元语法重点） 3.He often says that protecting the environment is not the same as doing a big project—it’s about sticking to small habits.（用not the same as明确环保的本质，逻辑清晰，提升作文深度） 【拓展1】 你的班级举办“环保行动分享会”，请你写一篇短文，描述你所在城市的一个环境问题，并提出具体的解决办法，词数不少于80。 An Environmental Problem in My City and Solutions ________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 【拓展1范文】 An Environmental Problem in My City and Solutions My city is facing a serious rubbish problem—streets, parks and even rivers are sometimes covered with litter. This not only makes the city look ugly but also pollutes the soil and water, harming plants and animals. The problem is caused by some people’s bad habits: they throw away plastic bags and food waste carelessly. To solve it, we need to take action together. First, the government should set up more dustbins and put up signs saying “Don’t litter”. Second, schools should educate students about environmental protection. Finally, each citizen should learn to recycle waste, such as paper and plastic bottles. Protecting the environment is the same as protecting our home. If everyone changes their bad habits and joins in environmental protection, our city will become cleaner and more beautiful. 【拓展1译文】 我所在城市的环境问题及解决办法 我的城市正面临一个严重的垃圾问题——街道、公园甚至河流有时都被垃圾覆盖。这不仅让城市看起来丑陋，还污染土壤和水源，危害动植物。 这个问题是由一些人的坏习惯造成的：他们随意丢弃塑料袋和食物垃圾。要解决这个问题，我们需要共同行动。首先，政府应该设置更多垃圾桶，并张贴“禁止乱扔垃圾”的标识。其次，学校应该教育学生保护环境。最后，每个市民都应该学会回收垃圾，比如纸张和塑料瓶。 保护环境就如同保护我们的家。如果每个人都改掉坏习惯，加入环保行列，我们的城市将会变得更干净、更美丽。 【拓展2】 请根据以下提示，仿写一篇“环保主题倡议信”，运用本单元核心语法，词数100左右，开头已给出。 提示 信息 核心内容 倡议对象（全体同学）、倡议背景（环境问题日益严重）、倡议内容（低碳出行、节约资源、垃圾分类）、呼吁行动 语言要求 运用like/the same as/different from等结构，贴合单元语法重点 Dear fellow students, Our planet is in danger due to serious environmental problems like air pollution and plastic waste. It’s time for us to take action to protect it, just like many environmental protectors do. ________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 【拓展2范文】 Dear fellow students, Our planet is in danger due to serious environmental problems like air pollution and plastic waste. It’s time for us to take action to protect it, just like many environmental protectors do. First, we should choose low-carbon ways to go to school, such as walking or cycling—this is different from taking cars that produce a lot of waste gas. Second, we need to save resources: turn off the lights when leaving rooms and reuse water if possible. Third, we should sort our rubbish, as different kinds of waste have different ways of disposal. Protecting the environment is not as difficult as we think. If we all stick to these small habits, our actions will be the same as a powerful force to save the planet. Let’s start from today and be green consumers who care about our environment! 【拓展2译文】 亲爱的同学们： 我们的星球正面临危险，空气污染、塑料垃圾等环境问题日益严重。现在是我们采取行动保护它的时候了，就像许多环保卫士所做的那样。 首先，我们应该选择低碳出行方式，比如步行或骑自行车——这和乘坐会产生大量废气的汽车不同。其次，我们要节约资源：离开房间时关灯，可能的话重复用水。第三，我们应该给垃圾分类，因为不同的垃圾有不同的处理方式。 保护环境并不像我们想象的那么难。如果我们都坚持这些小习惯，我们的行动将成为拯救星球的强大力量。让我们从今天开始，做关心环境的环保消费者吧！ 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.环境与环保相关（单元重点） · 环境问题：air pollution 空气污染；plastic waste 塑料垃圾；rubbish problem 垃圾问题；carbon dioxide emissions 二氧化碳排放；soil pollution 土壤污染；water pollution 水污染；greenhouse effect 温室效应 · 环保行动：save water 节约用水；reduce waste 减少浪费；recycle waste 回收垃圾；sort rubbish 垃圾分类；low-carbon life 低碳生活；turn off the lights 关灯；reuse paper 重复用纸；protect the environment 保护环境 · 语法相关：the same as 与……一样；different from 与……不同；like 像……一样；the same…as 与……相同的…… · 理念与人物：environmental protector 环保卫士；green consumer 环保消费者；set an example 树立榜样；make a difference 产生影响；environmental protection 环境保护 1. 语法相关（单元重点） · the same 与 different： · 基本用法：be the same（相同的）；be different（不同的），例：These two environmental plans are different.（这两个环保计划不同。） · like/the same as/different from： · like 表示“像……一样”，后接名词/代词，例：He lives like a green hero.（他像环保英雄一样生活。） · the same as 表示“与……一样”，例：His way of saving water is the same as mine.（他节水的方式和我一样。） · different from 表示“与……不同”，例：Her environmental habits are different from her brother’s.（她的环保习惯和她哥哥不同。） · the same + 名词 + as： · 后接名词/代词，例：We should use the same amount of electricity as we really need.（我们应该使用真正需要的电量。） 1. 表达类（单元基础） · 逻辑连接：first 首先；second 其次；finally 最后；such as 例如；for example 例如；if 如果；because 因为；but 但是 · 感悟表达：set a perfect example 树立完美榜样；stick to habits 坚持习惯；join in 加入；save the planet 拯救星球；cleaner and more beautiful 更干净更美丽 二、实用句型积累 1.介绍环保人物（贴合单元核心） · [Name] is a true environmental protector whose… [某人]是一位真正的环保卫士，他的……，例：Gary Green is a true environmental protector whose daily life is full of green habits. · He/She does… to… 他/她做……来……，例：He rides a bike to school to reduce carbon emissions. · His/Her lifestyle is different from… 他/她的生活方式与……不同，例：His lifestyle is different from people who waste resources. · He/She proves that… 他/她证明……，例：He proves that small actions can make a big difference. 1. 描述环境问题与解决办法（贴合单元主题） · [City/Place] is facing a serious environmental problem—… [城市/地方]正面临一个严重的环境问题——……，例：Our town is facing a serious environmental problem—plastic pollution. · The problem is caused by… 这个问题是由……造成的，例：The problem is caused by people’s careless littering. · To solve it, we can… 要解决它，我们可以……，例：To solve it, we can set up more recycling bins. · Protecting the environment is the same as protecting… 保护环境就如同保护……，例：Protecting the environment is the same as protecting our own homes. 1. 发出环保倡议（贴合单元内涵） · It’s time for us to take action to… 是我们采取行动……的时候了，例：It’s time for us to take action to save the earth. · We should… instead of… 我们应该……而不是……，例：We should reuse bags instead of using new plastic bags. · Just like…, we can… 就像……一样，我们可以……，例：Just like Gary Green, we can develop green habits in daily life. · Let’s start from… and be… 让我们从……开始，成为……，例：Let’s start from small things and be responsible environmental protectors. 三、课堂实用句型 · 提问句型：What environmental problems are there in our city?；How can we protect the environment in daily life?；What does Gary Green do to protect the environment?；Why is it important to recycle waste?；What’s the difference between green and non-green lifestyles? · 回答句型：There is too much rubbish in our city.；We can save water and electricity in daily life.；He rides a bike to school and uses both sides of paper.；Because recycling waste can reduce pollution.；Green lifestyles are different from non-green ones in saving resources. 学科网（北京）股份有限公司 $
