1. Save Water, Save Life
Water is one of the most important natural resources on Earth. However, many people waste water in their daily lives. For example, they leave the tap running while brushing their teeth or take long showers. These small actions may seem harmless, but they add up and cause serious water shortages in some areas.
To protect our planet, we should start with simple steps. We can turn off the tap while brushing, fix leaking pipes quickly, and collect rainwater for watering plants. If everyone does their part, we can save a lot of water and help future generations.
Protecting water resources is not only about saving water—it’s about saving life itself.
🍀中文翻译：
水是地球上最重要的自然资源之一。然而，许多人在日常生活中浪费水资源。例如，刷牙时让水龙头一直开着，或者长时间洗澡。这些小行为看似无害，但积少成多，会导致一些地区严重的水资源短缺。
为了保护地球，我们应该从简单的行动做起。刷牙时关掉水龙头、及时修理漏水的管道、收集雨水浇花等都是有效的方法。如果每个人都能尽一份力，我们就能节约大量水资源，造福后代。
保护水资源，不仅是节约用水，更是拯救生命本身。
✍️点评与重点：
- 重点词汇： natural resources（自然资源），water shortages（水资源短缺），leaking pipes（漏水的管道），rainwater（雨水）
- 句型亮点： “These small actions may seem harmless, but they add up...”（这些小行为看似无害，但积少成多）——适合用于说明微小行为的累积影响。
- 写作技巧： 采用“问题—解决方案—呼吁行动”结构，逻辑清晰，适合议论文写作。
2. Say No to Plastic Bags
Plastic bags are convenient, but they cause serious environmental problems. They are made from non-renewable resources and can take hundreds of years to break down. When thrown away, they often end up in oceans, harming sea animals.
Instead of using plastic bags, we should bring reusable cloth bags when shopping. Many countries have already banned or taxed plastic bags to reduce their use. As students, we can also spread awareness by telling our families and friends about the dangers of plastic pollution.
Every time we refuse a plastic bag, we make a small but meaningful difference to the environment.
🍀中文翻译：
塑料袋虽然方便，但会造成严重的环境问题。它们由不可再生资源制成，可能需要数百年才能分解。被丢弃后，它们常常进入海洋，危害海洋生物。
我们购物时应自带可重复使用的布袋，而不是使用塑料袋。许多国家已经禁止或对塑料袋征税，以减少其使用。作为学生，我们也可以通过向家人和朋友宣传塑料污染的危害来提高环保意识。
每一次拒绝塑料袋，都是对环境做出的一次微小却有意义的改变。
✍️点评与重点：
- 重点词汇： non-renewable resources（不可再生资源），break down（分解），reusable（可重复使用的），plastic pollution（塑料污染）
- 句型亮点： “Every time we refuse..., we make a small but meaningful difference...”（每次我们拒绝……就做出了微小却有意义的改变）——情感真挚，适合结尾升华。
- 写作技巧： 使用具体例子（如国家政策）增强说服力，体现思辨能力。
3. Go Green with Public Transportation
With the increase in private cars, air pollution has become a serious problem in many cities. Cars release harmful gases like carbon dioxide, which contribute to global warming.
One effective way to reduce pollution is to use public transportation, such as buses and subways. Not only does it reduce traffic and emissions, but it also saves money. Riding bikes or walking for short trips is even better for both health and the environment.
If more people choose green travel, our cities will become cleaner and more livable. Let’s leave a healthier planet for the next generation.
🍀中文翻译：
随着私家车数量的增加，许多城市的空气污染问题日益严重。汽车排放的二氧化碳等有害气体加剧了全球变暖。
减少污染的一个有效方法是使用公共交通，如公交车和地铁。这不仅能减少交通拥堵和尾气排放，还能节省开支。短途出行时骑自行车或步行，对健康和环境更有益。
如果更多人选择绿色出行，我们的城市将变得更清洁、更宜居。让我们为下一代留下一个更健康的地球。
✍️点评与重点：
- 重点词汇： air pollution（空气污染），carbon dioxide（二氧化碳），global warming（全球变暖），public transportation（公共交通）
- 句型亮点： “Not only does it reduce..., but it also saves...”（不仅减少……而且节省……）——经典并列句式，增强表达力度。
- 写作技巧： 从问题出发，提出多种解决方案，体现全面思考。
4. Plant More Trees, Breathe Better
Trees are nature’s air purifiers. They absorb carbon dioxide and release oxygen, helping to fight climate change. Unfortunately, deforestation is happening at an alarming rate around the world.
We can help by planting trees in our communities. Schools can organize tree-planting activities, and families can grow small gardens at home. Even a single tree can make a difference by providing shade, reducing pollution, and offering a home to birds and insects.
Let’s take action now. The more trees we plant today, the better air we will breathe tomorrow.
🍀中文翻译：
树木是大自然的空气净化器。它们吸收二氧化碳并释放氧气，有助于应对气候变化。然而，全球范围内的森林砍伐速度令人担忧。
我们可以通过在社区植树来帮助改善环境。学校可以组织植树活动，家庭也可以在家种植小花园。即使一棵树也能带来改变：提供阴凉、减少污染，并为鸟类和昆虫提供栖息地。
让我们立即行动起来。今天种下的树越多，明天我们呼吸的空气就越清新。
✍️点评与重点：
- 重点词汇： air purifiers（空气净化器），deforestation（森林砍伐），climate change（气候变化），shade（阴凉）
- 句型亮点： “The more..., the better...”（越……越……）——经典比较结构，适合用于强调因果关系。
- 写作技巧： 使用拟人化表达（如“nature’s air purifiers”）增强语言生动性。
5. Start Recycling at Home
Every day, households produce a large amount of waste. Much of this waste, such as paper, plastic, and glass, can be recycled. However, many people still throw everything into one trash can.
Recycling helps save energy and reduces the need for landfills. We can start by separating recyclable materials at home. For example, keep a box for old newspapers and bottles. Schools and neighborhoods can also set up recycling stations to make it easier for everyone.
Recycling is not difficult—just requires a little effort and habit. Let’s turn waste into treasure and protect our Earth together.
🍀中文翻译：
每天，家庭都会产生大量垃圾。其中许多垃圾，如纸张、塑料和玻璃，是可以回收的。然而，许多人仍然把所有垃圾都扔进同一个垃圾桶。
回收利用有助于节约能源，减少对垃圾填埋场的需求。我们可以从在家分类可回收物开始。例如，准备一个箱子专门存放旧报纸和瓶子。学校和社区也可以设立回收站，方便大家参与。
回收并不难，只需要一点努力和养成习惯。让我们变废为宝，共同保护我们的地球。
✍️点评与重点：
- 重点词汇： households（家庭），recyclable materials（可回收物），landfills（垃圾填埋场），recycling stations（回收站）
- 句型亮点： “Recycling is not difficult—just requires a little effort and habit.”（回收并不难，只需要一点努力和习惯）——简洁有力，适合总结观点。
- 写作技巧： 强调“从小事做起”的理念，贴近生活，易于共鸣。
