Guardians of the Green
Saturday morning, and the environmental club was gathering at the gate of the national park. Today was volunteer day: the students' mission was to collect rubbish along the trails and record observations of wildlife for the park's research centre. Each of them received a pair of gloves, a bag, and a clipboard. 'Remember,' the ranger said, 'every piece of plastic you pick up is a gift to the forest.'
周六早上，环保社团在国家公园门口集合。今天是志愿者日：学生们的任务是沿步道捡拾垃圾，并为公园研究中心记录野生动物观察数据。每人领到一副手套、一个袋子和一块记录板。“记住，”护林员说，“你们捡起的每片塑料，都是给森林的礼物。”
The trail wound through dense forest, and the morning light filtered through the leaves like golden rain. They found plastic bags hidden in the bushes, bottles beside the stream, and candy wrappers under the benches. Han Mei recorded every piece of data carefully, noting the location of each item. 'These numbers will help the park understand where the problem is,' she explained. The ranger had told them that every piece of data would help protect the park for the next generation.
小路蜿蜒穿过茂密的森林，晨光透过树叶洒落，像金色的雨。他们在灌木丛里发现塑料袋，在小溪边发现瓶子，在长椅下发现糖果包装纸。Han Mei 认真记录每一条数据，标注每个物品的位置。“这些数字会帮助公园了解问题在哪里，”她解释说。护林员告诉过他们，每一条数据都会帮助保护公园，留给下一代。
At noon, they rested under the shade of an ancient tree, sharing bread and watching birds migrate across the sky in graceful lines. 'This park feels like a living museum,' Jack said, munching his sandwich. 'Every species here has its own story.' Li Lei nodded, thinking about how the delicate ecosystem depended on the careful balance of every creature within it. Li Lei counted eleven kinds of birds before lunch, a new record for the club.
中午，他们在古树的树荫下休息，分享面包，看鸟儿排成优雅的队列飞过天空。“这个公园就像一座活的博物馆，”Jack 边吃三明治边说，“这里的每个物种都有自己的故事。”李雷点点头，想着这脆弱的生态系统如何依赖其中每个生物之间的微妙平衡。午饭前李雷数到十一种鸟，创下社团新纪录。
A park ranger joined them and told stories about the reserve. 'Our boundary line protects more than trees,' he said. 'It protects the habitat of rare species, from the birds of the dense forest to the marine life along the wetland coast. Every territory has a guardian, and today, that guardian is you.' The students felt a new sense of pride.
一位公园护林员加入他们，讲起保护区的故事。“我们的边界线保护的不仅是树木，”他说，“它保护着珍稀物种的栖息地，从密林中的鸟类到湿地沿岸的海洋生物。每片领地都有守护者，而今天，守护者就是你们。”学生们心中涌起一种新的自豪感。
In the late afternoon, Cozy teacher arrived with a thermos of hot tea. She looked at the filled rubbish bags and smiled. 'Protecting nature is not a distant dream,' she said, pouring tea into small cups. 'It begins with small actions, exactly like the ones you took today. Remember, the earth does not belong to us; we belong to the earth.' Her words warmed them more than the tea, and the tiredness seemed to lift a little.
傍晚，Cozy 老师带着一壶热茶来了。她看着装满的垃圾袋，微笑着说：“保护自然不是遥远的梦想，它始于小小的行动，就像你们今天所做的一样。记住，地球不属于我们；我们属于地球。”她的话比茶更暖，疲惫似乎也减轻了一些。
By sunset, they had filled twelve bags and recorded forty observations. Tired but happy, the guardians of the green walked back along the trail. Jack looked up at the darkening sky and said, 'I used to think volunteering was boring. Now I understand: it is the most beautiful kind of love.' They planned their next visit before the bus even started its engine. The bus ride home was full of happy talk about the next volunteer day.
日落时，他们捡满了十二袋垃圾，记录了四十条观察。疲惫而快乐的绿色守护者们沿小路返回。Jack 望着渐暗的天空说：“我以前觉得做志愿者很无聊，现在我明白了：这是最美好的一种爱。”公交车还没发动，他们就已经计划好了下一次来访。回家的车上，大家兴奋地讨论着下一次志愿者日。
