I realize that many rivers are full of plastic waste now. The pollution mainly comes from people’s daily rubbish and factory waste. Because factories pour dirty water into rivers, the water is so dirty that lots of fish die every year. While some students go to clean rivers on weekends, the pollution is still serious. We must take action before the problem gets worse. If everyone stops throwing plastic into water, rivers will become clean again. We can’t protect our rivers unless every citizen follows green rules. I believe that small changes from each person can make a big difference. Let’s reduce waste and protect clean water together! 中文翻译 我们十分担忧城市周边的水污染问题。我发现如今许多河道堆满塑料垃圾。 污染主要来自人们生活垃圾与工厂废水。因为工厂向河道排放污水，水质变得极差，大量鱼类每年因此死亡。虽然有部分学生周末清理河道，但污染依旧严峻。 我们必须趁早采取行动。如果所有人不再向水中丢弃塑料，河流会重归清澈。除非每位市民遵守绿色准则，否则我们无法守护河道。 我相信每个人微小的改变都能带来巨大改变。让我们减少垃圾，一同保护洁净水源！ 六、核心素材（好词、从句加分句型、谚语） （一）高频环保好词 1. plastic waste 塑料垃圾 2. cut down pollution 减少污染 3. three Rs: reduce, reuse, recycle 减量化、再利用、回收 4. pour waste water 排放废水 5. environmental protection 环境保护 6. make a difference 产生影响 7. follow green rules 遵守环保准则 8. citizen n. 市民 （二）单元语法加分从句（作文必用） 1. 原因状语从句（because） Many rivers are dirty because factories pour waste into them. 2. 让步状语从句（while） While we recycle bottles, we still produce too much plastic. 3. 结果状语从句（so…that） The air is so bad that we can’t go out without masks. 4. 条件状语从句（if /unless） If we reuse shopping bags, we will produce less waste.
