1. 环保的重要性（The Importance of Environmental Protection）
Environmental protection is becoming more and more important in today's world. With the rapid development of industry and population growth, natural resources are being used up quickly. Air and water pollution are serious problems in many cities. If we do not take action now, our planet may become unsuitable for living. Everyone should play a part in protecting the environment. Simple actions like saving water, turning off lights when not in use, and using public transportation can make a big difference. We must remember that protecting the environment is not only the government's duty, but also the responsibility of every citizen.
在当今世界，环境保护变得越来越重要。随着工业的快速发展和人口的增长，自然资源正在被迅速消耗。空气和水污染在许多城市已成为严重问题。如果我们现在不采取行动，地球可能将不再适合居住。每个人都应参与环境保护。节约用水、随手关灯、使用公共交通等简单行为都能产生重大影响。我们必须记住，保护环境不仅是政府的责任，也是每个公民的义务。
✍️点评与重点：本文使用了“natural resources”（自然资源）、“air and water pollution”（空气和水污染）等高中常见环保词汇。句型结构清晰，如“If we do not...”和“not only... but also...”是写作中常用的复合句，适合模仿。重点句型：Everyone should play a part in... 可用于多种主题作文。
2. 我能为环保做什么？（What Can I Do for the Environment?）
Although I am just a high school student, I believe I can still do something to help protect the environment. First, I try to reduce waste by using both sides of paper and avoiding single-use plastic bags. Second, I always separate my trash into recyclable and non-recyclable parts. Third, I ride my bike to school instead of asking my parents to drive me. These small actions may seem unimportant, but if everyone does them, they can lead to big changes. I also encourage my friends and family to live a greener life. Protecting the environment starts with small steps, and I am proud to be part of the solution.
虽然我只是一名高中生，但我相信我仍可以做一些事情来帮助保护环境。首先，我通过纸张双面使用、避免使用一次性塑料袋来减少浪费。其次，我总是把垃圾分类为可回收和不可回收两类。第三，我骑自行车上学，而不是让父母开车送我。这些小行为看似微不足道，但如果人人都这样做，就能带来巨大改变。我还鼓励朋友和家人过更环保的生活。保护环境始于微小行动，我为自己成为解决方案的一部分而感到自豪。
✍️点评与重点：本文以第一人称写作，情感真挚，适合考试中“个人做法”类题目。使用了“reduce waste”（减少浪费）、“separate trash”（垃圾分类）等实用表达。亮点句型：Although I am just... I believe... 展现积极态度，可用于开头段。动词短语如“lead to big changes”和“be part of the solution”值得积累。
3. 塑料污染的危害（The Harm of Plastic Pollution）
Plastic pollution has become a serious global problem. Every year, millions of tons of plastic waste end up in the oceans, harming sea animals and ecosystems. Sea turtles often mistake plastic bags for jellyfish and eat them, which can cause death. Moreover, plastic takes hundreds of years to break down, and tiny plastic pieces can enter the food chain, even reaching humans. To solve this problem, we should use fewer plastic products and choose reusable alternatives like cloth bags and glass bottles. Governments should also make stricter rules to control plastic production and encourage recycling. Only by working together can we reduce plastic pollution and protect our planet.
塑料污染已成为一个严重的全球性问题。每年，数百万吨塑料垃圾最终流入海洋，危害海洋生物和生态系统。海龟常常把塑料袋误认为水母并吃掉，这可能导致死亡。此外，塑料需要数百年才能分解，微小的塑料颗粒可能进入食物链，甚至到达人体。为解决这一问题，我们应减少使用塑料制品，选择布袋、玻璃瓶等可重复使用的替代品。政府也应制定更严格的法规，控制塑料生产并鼓励回收利用。只有共同努力，我们才能减少塑料污染，保护地球。
✍️点评与重点：本文聚焦具体环境问题——塑料污染，逻辑清晰，数据支撑有力。关键词汇如“end up in the oceans”（最终流入海洋）、“enter the food chain”（进入食物链）为高分表达。使用“mistake... for...”（把……误认为……）和“not only... but also...”结构增强语言多样性。结尾句Only by working together... 是议论文常用升华句型。
4. 绿色生活方式（Green Lifestyle）
Living a green lifestyle means making choices that are good for the environment. This includes saving energy, reducing waste, and protecting natural resources. For example, I turn off the tap while brushing my teeth to save water, and I use a fan instead of air conditioning when possible. I also buy second-hand books and clothes to reduce the need for new production. A green lifestyle may require some effort, but it brings long-term benefits to both people and the planet. If more people choose to live green, we can create a cleaner, healthier, and more sustainable world for future generations.
过一种绿色的生活方式意味着做出对环境有益的选择。这包括节约能源、减少浪费和保护自然资源。例如，我刷牙时会关掉水龙头以节约用水，可能的情况下使用风扇而不是空调。我还购买二手书和衣物，以减少对新产品生产的需求。绿色生活方式可能需要一些努力，但它能为人类和地球带来长期益处。如果越来越多的人选择绿色生活，我们就能为子孙后代创造一个更清洁、更健康、更可持续的世界。
✍️点评与重点：本文主题贴近生活，易于引起共鸣。使用了“living a green lifestyle”、“sustainable world”等高级短语。动词搭配如“make choices”、“bring benefits”、“create a world”结构规范，适合模仿。亮点句型：If more people choose to..., we can... 可用于呼吁类结尾段。文中“second-hand books”等表达体现语言真实性和实用性。
