范文一：The Urgency of Climate Action
Climate change is no longer a distant threat; it is a present crisis. Rising global temperatures, melting ice caps, and extreme weather events are clear indicators that our planet is under stress. As university students, we must recognize our responsibility in mitigating this crisis. Simple actions—such as reducing energy consumption, using public transportation, and supporting sustainable policies—can collectively make a significant difference. Education and awareness are key: by spreading knowledge about climate change, we empower others to act.
气候变化已不再是遥远的威胁，而是一场现实的危机。全球气温上升、冰川融化以及极端天气频发，都是地球不堪重负的明显信号。作为大学生，我们必须意识到自己在缓解这场危机中的责任。减少能源消耗、使用公共交通、支持可持续政策等简单行为，都能产生显著的集体影响。教育与意识至关重要：通过传播气候变化的知识，我们能激励他人采取行动。
✍️点评与重点：本文使用“mitigating”（缓解）、“collectively”（集体地）、“empower”（赋能）等大学水平词汇，句式结构清晰，逻辑递进。适合用于议论文开头段或独立短文写作。重点句型：“...are clear indicators that...”可用于描述现象与因果关系。
范文二：Plastic Pollution and Its Impact on Marine Life
Plastic pollution has become one of the most pressing environmental issues of our time. Every year, millions of tons of plastic waste enter the oceans, endangering marine species and disrupting ecosystems. Sea turtles mistake plastic bags for jellyfish, and seabirds ingest microplastics, often leading to fatal consequences. Beyond the immediate harm to animals, plastic contamination also enters the human food chain through seafood. To combat this, we must reduce single-use plastics, promote biodegradable alternatives, and advocate for stricter waste management policies.
塑料污染已成为当今最紧迫的环境问题之一。每年有数百万吨塑料垃圾进入海洋，威胁海洋生物并破坏生态系统。海龟将塑料袋误认为水母，海鸟则摄入微塑料，常常导致致命后果。除了对动物的直接伤害，塑料污染还通过海产品进入人类食物链。为应对这一问题，我们必须减少一次性塑料使用，推广可降解替代品，并倡导更严格的垃圾管理政策。
✍️点评与重点：“pressing environmental issues”、“disrupting ecosystems”、“ingest microplastics”等表达精准且具学术性。“mistake...for...”是描述误解行为的常用句型。建议学习“advocate for”（倡导）这一动词短语，常用于政策类写作。
范文三：The Role of Renewable Energy in Sustainable Development
Sustainable development hinges on our ability to transition from fossil fuels to renewable energy sources such as solar, wind, and hydropower. These clean energy alternatives not only reduce greenhouse gas emissions but also promote energy independence and long-term economic stability. Governments and institutions must invest in green technology and incentivize innovation. As future leaders, university students should support research in renewable energy and raise public awareness about its benefits.
可持续发展取决于我们能否从化石燃料成功过渡到太阳能、风能和水能等可再生能源。这些清洁能源不仅能减少温室气体排放，还能促进能源独立和长期经济稳定。政府和机构必须投资绿色技术，并激励创新。作为未来的领导者，大学生应支持可再生能源的研究，并提高公众对其益处的认识。
✍️点评与重点：“hinges on”（取决于）是高级表达，替代常见的“depends on”。“incentivize innovation”（激励创新）是政策类写作高频短语。全文逻辑清晰，适合作为议论文主体段落使用。注意“energy independence”这一术语，常用于能源安全讨论。
范文四：Green Campus Initiatives: A Student’s Perspective
Creating a green campus is not solely the responsibility of university administrators—it requires active participation from students. Initiatives such as campus recycling programs, tree-planting events, and energy-saving campaigns can foster environmental consciousness. Universities can also integrate sustainability into the curriculum, encouraging interdisciplinary research on environmental issues. As students, we can form eco-clubs, organize awareness workshops, and lead by example in our daily habits, from using reusable bottles to minimizing paper waste.
建设绿色校园不仅是大学管理者的事，更需要学生的积极参与。校园回收项目、植树活动和节能宣传等举措有助于培养环保意识。高校还可将可持续发展理念融入课程，鼓励对环境问题的跨学科研究。作为学生，我们可以组建环保社团、组织宣传讲座，并在日常生活中以身作则，如使用可重复使用的水瓶、减少纸张浪费等。
✍️点评与重点：“foster environmental consciousness”（培养环保意识）是亮点表达。“integrate...into the curriculum”（将……融入课程）适用于教育类话题。“lead by example”（以身作则）是常见但有力的短语。建议积累“interdisciplinary research”（跨学科研究）这一学术术语。
范文五：Individual Responsibility in Environmental Protection
While governments and corporations play a major role in environmental protection, individual actions should not be underestimated. Every choice we make—from the products we buy to the way we commute—has an environmental footprint. By adopting a minimalist lifestyle, reducing meat consumption, and choosing eco-friendly transportation, we contribute to a healthier planet. Moreover, personal responsibility inspires collective change: when one person acts sustainably, others are more likely to follow. Environmental stewardship begins with the choices we make every day.
尽管政府和企业在环境保护中发挥重要作用，但个人行为也不容忽视。我们所做的每一个选择——从购买的商品到出行方式——都会留下环境足迹。通过践行极简生活方式、减少肉类消费、选择环保交通工具，我们都能为地球健康贡献力量。此外，个人责任感能激发集体改变：当一个人践行可持续生活时，他人更可能效仿。环境保护的责任始于我们每天的选择。
✍️点评与重点：“environmental footprint”（环境足迹）是核心术语，类比“carbon footprint”。“minimalist lifestyle”（极简生活）反映现代环保理念。“inspires collective change”体现行为的涟漪效应。结尾句升华主题，适合作为文章收尾句型学习。
