环保主题英语作文1：保护地球，从我做起
Nowadays, the environment is becoming worse and worse. Air pollution, water pollution, and too much rubbish are big problems. We must protect our Earth. I try to do small things every day. I turn off the lights when I leave the room. I use a cloth bag instead of plastic bags. I also ride my bike to school. These small actions can help the Earth a lot. If everyone does something, our world will become cleaner and greener.
如今，环境变得越来越差。空气污染、水污染和大量垃圾都是大问题。我们必须保护地球。我每天努力做些小事：离开房间时关灯，用布袋代替塑料袋，还骑自行车上学。这些小行为能大大帮助地球。如果每个人都行动起来，我们的世界将变得更干净、更绿。
✍️点评与重点：本文使用简单句和常见词汇，适合初中生模仿。重点句型如“I try to do...”、“If everyone does...”可用于表达个人行动与集体影响。关键词：turn off, instead of, ride a bike — 实用环保动词短语。
环保主题英语作文2：节约用水的重要性
Water is very important for life. But many people waste water every day. They leave the tap running when brushing teeth or washing hands. We must save water. I always turn off the tap when I’m not using it. My family also collects rainwater to water plants. Saving water is not hard. It just needs a little care. If we don’t save water now, there may be no clean water in the future.
水对生命非常重要。但许多人每天都在浪费水，比如刷牙或洗手时让水龙头一直开着。我们必须节约用水。我不用水时总会关掉水龙头，我家还收集雨水来浇花。节约用水并不难，只需要一点细心。如果我们现在不节水，将来可能就没有干净的水了。
✍️点评与重点：文章结构清晰：问题—行动—呼吁。使用“not...but...”、“if...”等连接词增强逻辑性。重点词汇：tap（水龙头），collect rainwater（收集雨水），future（未来）— 均为中考高频词。
环保主题英语作文3：垃圾分类，人人有责
In many cities, people are learning to sort their rubbish. There are different bins for paper, plastic, glass, and food waste. Sorting rubbish helps recycling and reduces pollution. In my school, we have a ‘Green Week’ to teach students how to recycle. I now put used bottles in the plastic bin and old newspapers in the paper bin. Everyone should learn to sort rubbish. It’s a small step, but a big help for the Earth.
在许多城市，人们正在学习垃圾分类。纸张、塑料、玻璃和厨余垃圾都有不同的垃圾桶。垃圾分类有助于回收利用，减少污染。我们学校开展了“绿色周”活动，教学生如何回收。我现在会把用过的瓶子放进塑料桶，旧报纸放进纸类桶。每个人都应学会分类垃圾。这是一小步，却对地球是大帮助。
✍️点评与重点：使用现在进行时（are learning）和具体例子增强真实感。关键词组：sort rubbish（垃圾分类），recycling（回收），reduce pollution（减少污染）— 实用且易记。句型“It’s a small step, but a big help”可用于多种主题作文结尾。
