1. 保护环境，从我做起
Protecting the environment starts with each of us. Every day, we produce waste, use plastic bags, and consume a lot of energy. However, small changes in our daily lives can make a big difference. For example, we can bring reusable shopping bags, turn off the lights when leaving a room, and recycle paper and bottles. If everyone does their part, we can reduce pollution and save natural resources. It is our responsibility to care for the Earth, not only for ourselves but also for future generations.
保护环境要从每个人做起。每天我们都会制造垃圾，使用塑料袋，消耗大量能源。然而，日常生活中的一些小改变可以带来巨大影响。例如，我们可以自带可重复使用的购物袋，离开房间时关灯，对纸张和瓶子进行回收。如果人人都尽一份力，我们就能减少污染，节约自然资源。保护地球是我们的责任，不仅为了我们自己，也为了子孙后代。
✍️【点评与重点】 本文结构清晰，使用了“starts with each of us”“make a big difference”等常见但有力的表达。重点词汇如“reusable”（可重复使用的）、“recycle”（回收）、“natural resources”（自然资源）是环保类作文的高频词，建议背诵掌握。
2. 塑料污染的危害与应对
Plastic pollution has become a serious problem around the world. Millions of tons of plastic waste end up in the oceans every year, harming sea life and entering the food chain. Many animals mistake plastic for food and die as a result. To solve this problem, governments should ban single-use plastics, and people should use eco-friendly alternatives like cloth bags and glass containers. Education is also important—schools can teach students about the dangers of plastic and how to reduce their use.
塑料污染已成为全球严重的环境问题。每年有数百万吨塑料垃圾流入海洋，危害海洋生物并进入食物链。许多动物误食塑料，最终导致死亡。为解决这一问题，政府应禁止一次性塑料制品，人们应使用环保替代品，如布袋和玻璃容器。教育也很重要——学校可以向学生传授塑料的危害以及如何减少使用。
✍️【点评与重点】 文章使用了“end up in”“harming sea life”“enter the food chain”等生动表达，增强了说服力。关键词“single-use plastics”（一次性塑料）和“eco-friendly alternatives”（环保替代品）是写作加分项，适合在议论文中引用。
3. 气候变化：我们面临的挑战
Climate change is one of the biggest challenges facing our planet today. Rising temperatures, extreme weather, and melting ice caps are clear signs of global warming. Human activities, especially burning fossil fuels, are the main cause. To fight climate change, we need to use clean energy like solar and wind power. We should also plant more trees, as they absorb carbon dioxide. If we act now, we can slow down the process and protect our environment for the future.
气候变化是当今地球面临的最大挑战之一。气温上升、极端天气和冰盖融化都是全球变暖的明显迹象。人类活动，尤其是燃烧化石燃料，是主要原因。为应对气候变化，我们需要使用太阳能和风能等清洁能源。我们还应多种树，因为树木可以吸收二氧化碳。如果我们现在行动，就能减缓这一过程，为未来保护环境。
✍️【点评与重点】 本文逻辑严密，使用了“one of the biggest challenges”“clear signs of”“main cause”等典型议论文句型。重点短语“fossil fuels”（化石燃料）、“carbon dioxide”（二氧化碳）、“clean energy”是环保类话题的核心词汇，建议熟练掌握。
4. 绿色生活：一种可持续的选择
Living a green life means making choices that are good for the environment. This includes walking or riding a bike instead of driving, saving water, and eating less meat. A green lifestyle not only helps the planet but also improves our health. For example, walking reduces air pollution and keeps us fit. Schools and communities can encourage green living by organizing clean-up events and promoting environmental awareness. When more people choose to live sustainably, the world becomes a better place.
绿色生活意味着做出对环境有益的选择。这包括步行或骑自行车代替开车，节约用水，减少肉类摄入。绿色生活方式不仅有助于地球，也能改善我们的健康。例如，步行减少了空气污染，同时让我们保持健康。学校和社区可以通过组织清洁活动和宣传环保意识来鼓励绿色生活。当越来越多人选择可持续的生活方式时，世界将变得更美好。
✍️【点评与重点】 本文语言自然流畅，使用了“making choices”“not only... but also...”“encourage”等连接词，使文章更具连贯性。关键词“sustainable”（可持续的）、“environmental awareness”（环保意识）是高级表达，适合在高分作文中使用。
