My School Life

In my school life, I have learned many new words that help me understand the world better. For example, when I read about environmental protection, I came across the word *sustainability* (可持续性), which means using resources wisely so they won't run out. Another important term is *carbon footprint* (碳足迹), referring to the total amount of greenhouse gases produced by human activities.

One day, our teacher asked us to write an essay on how to reduce waste. I wrote about recycling paper and plastic bottles. The key idea was to reuse materials instead of throwing them away. This concept is called *upcycling* (升级改造), where old items are transformed into something useful again.

I also studied the word *ecosystem* (生态系统), which describes how living things and their environment interact. Protecting ecosystems is crucial for keeping nature balanced.

Through these lessons, I realized that learning English vocabulary not only improves my writing skills but also helps me think critically about global issues like climate change.

我的校园生活

在我的校园生活中，我学会了许多新单词，它们帮助我更好地理解世界。例如，当我阅读有关环境保护的文章时，遇到了*sustainability*（可持续性）这个词，意思是明智地使用资源使其不会枯竭。另一个重要概念是*carbon footprint*（碳足迹），指的是人类活动产生的温室气体总量。

有一天，我们的老师让我们写一篇关于减少浪费的作文。我写了关于回收纸张和塑料瓶的例子。关键思想是重复利用材料而非丢弃。这一概念被称为*upcycling*（升级改造），即把旧物品改造成更有价值的产品。

我还学习了*ecosystem*（生态系统）这个词，它描述了生物与其环境之间的相互作用。保护生态系统对维持自然平衡至关重要。

通过这些课程，我意识到学习英语词汇不仅能提升写作能力，还能帮助我批判性地思考全球议题，如气候变化。
