1. 环保的重要性（The Importance of Environmental Protection）
Environmental protection is one of the most important issues in today’s world. With the rapid development of industry and population growth, our planet is facing serious environmental problems such as air pollution, water pollution, and global warming. If we do not take action now, these problems will become worse and may even threaten human survival. Everyone should play a role in protecting the environment. Simple actions like turning off lights when not in use, recycling waste, and using public transportation can make a big difference. Protecting the environment is not only about saving nature, but also about ensuring a better future for ourselves and the next generation.
环境保护是当今世界最重要的问题之一。随着工业的快速发展和人口的增长，我们的地球正面临着空气污染、水污染和全球变暖等严重环境问题。如果我们现在不采取行动，这些问题将变得更加严重，甚至可能威胁到人类的生存。每个人都应该在保护环境中发挥作用。像不用电时关灯、回收废物、使用公共交通等简单行为都能产生巨大影响。保护环境不仅是为了拯救自然，也是为了确保我们自己和下一代拥有更美好的未来。
✍️点评与重点：本文开头点明主题，使用“one of the most important issues”增强说服力。词汇如“rapid development”“global warming”“threaten human survival”属于高中高频环保类表达，适合写作积累。句式结构多样，如条件句“If we do not...”和并列句“not only... but also...”值得模仿。
2. 我能为环保做什么？（What Can I Do for the Environment?）
As a high school student, I may not have the power to change the world, but I believe small actions can lead to big changes. I start by reducing my use of plastic bags and bottles. Instead, I carry a reusable water bottle and shopping bag. I also try to save energy by turning off the lights and unplugging devices when they are not in use. At school, I join the environmental club and help organize clean-up activities in our neighborhood. I even encourage my family and friends to live a greener lifestyle. Though these actions seem small, together they can create a positive impact on the environment.
作为一名高中生，我可能没有改变世界的力量，但我相信小行动可以带来大改变。我从减少使用塑料袋和塑料瓶开始。我随身携带可重复使用的水瓶和购物袋。我还通过在不使用时关灯和拔掉电器插头来节约能源。在学校，我加入了环保社团，帮助组织社区清洁活动。我甚至鼓励家人和朋友过更环保的生活方式。尽管这些行动看似微小，但它们共同能对环境产生积极影响。
✍️点评与重点：使用第一人称增强真实感，“small actions can lead to big changes”是经典句型。动词短语如“reduce the use of”“carry a reusable...”“unplugging devices”实用性强，适合高中生模仿。结尾总结升华，体现逻辑完整性。
3. 塑料污染的危害（The Harm of Plastic Pollution）
Plastic pollution has become a serious problem around the world. Every year, millions of tons of plastic waste are thrown into the oceans, harming marine life and ecosystems. Sea turtles, for example, often mistake plastic bags for jellyfish and eat them, which can lead to death. Plastic does not break down easily and can remain in the environment for hundreds of years. To reduce plastic pollution, governments should ban single-use plastics, and people should choose eco-friendly alternatives. We must act now to protect our oceans and all living creatures that depend on them.
塑料污染已成为全球严重的环境问题。每年，数百万吨塑料垃圾被倒入海洋，危害海洋生物和生态系统。例如，海龟常常把塑料袋误认为水母并吃下，这可能导致死亡。塑料难以分解，可在环境中存在数百年。为了减少塑料污染，政府应禁止一次性塑料制品，人们应选择环保替代品。我们必须立即行动，保护我们的海洋以及依赖海洋生存的所有生物。
✍️点评与重点：举例说明（如海龟）增强文章感染力。“mistake... for...”“harming marine life”“eco-friendly alternatives”是环保类写作关键词汇。使用“should”提出建议，语气恰当。数据“millions of tons”增加说服力，适合议论文引用。
4. 绿色出行的好处（The Benefits of Green Transportation）
Green transportation refers to ways of traveling that are environmentally friendly, such as walking, cycling, and using public transport. These methods produce less air pollution and help reduce traffic congestion. For example, riding a bike to school not only saves energy but also keeps me healthy. Taking the bus or subway instead of driving a car can greatly lower carbon emissions. Schools and cities should encourage green transportation by building more bike lanes and improving public transit systems. If more people choose green travel, our cities will become cleaner and more livable.
绿色出行是指环保的交通方式，如步行、骑自行车和乘坐公共交通工具。这些方式产生的空气污染较少，并有助于缓解交通拥堵。例如，骑自行车上学不仅节约能源，还能让我保持健康。乘坐公交车或地铁而不是开车，可以大幅降低碳排放。学校和城市应通过建设更多自行车道和改善公共交通系统来鼓励绿色出行。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。
✍️点评与重点：定义开头清晰明了。“refers to”“produce less pollution”“reduce traffic congestion”是实用表达。“not only... but also...”结构展示语言能力。结尾提出建议，体现思辨性，适合高考写作结构。
5. 拯救地球，刻不容缓（Saving the Earth: It’s Time to Act）
The Earth is our only home, but human activities are destroying it at an alarming rate. Forests are being cut down, animals are losing their habitats, and the climate is changing faster than ever. If we continue like this, future generations may not have a healthy planet to live on. The good news is that it’s not too late to make a change. We can plant more trees, protect endangered species, and support renewable energy. Every person has a responsibility to care for the Earth. Let’s work together to save our planet before it’s too late.
地球是我们唯一的家园，但人类活动正以惊人的速度破坏它。森林被砍伐，动物失去栖息地，气候以前所未有的速度变化。如果我们继续这样下去，后代可能将没有一个健康的星球可以居住。好消息是，现在改变还为时不晚。我们可以多植树，保护濒危物种，支持可再生能源。每个人都有责任关爱地球。让我们共同努力，在为时已晚之前拯救我们的星球。
✍️点评与重点：情感强烈，使用“only home”“alarming rate”“not too late”等词增强感染力。排比句“Forests are... animals are... climate is...”增强节奏感。结尾呼吁行动（call to action）是优秀作文的常见结尾方式，值得学习。
