作文结构：经典三段式
英语考试作文通常采用“引言—主体—的三段式结构，逻辑清晰，便于阅卷老师快速抓取重点。
引言（Introduction）
用1-2句话概括主题，点明气候变化的严重性，可引用数据或现象增强说服力。
例句：
- Climate change has become one of the most pressing issues in the 21st century, with rising global temperatures and extreme weather events threatening ecosystems and human societies.
- According to NASA, the Earth’s average temperature has increased by 1.2°C since the late 19th century, primarily due to human activities.
主体（Body Paragraphs）
分2-3段展开，每段讨论一个核心点，
- 原因分析（Causes）：工业排放、 deforestation（森林砍伐）、化石燃料使用等。
- 影响分析（Effects）：海平面上升、物种灭绝、农业减产等。
- 解决方案（Solutions）：推广可再生能源、减少碳足迹、政府政策等。
高级词汇与短语：
- Greenhouse gas emissions（温室气体排放）
- Carbon footprint（碳足迹）
- Renewable energy（可再生能源）
- Sustainable development（可持续发展）
例句：
- The primary cause of climate change is the excessive burning of fossil fuels, which releases large amounts of CO2 into the atmosphere.
- To mitigate this crisis, governments should invest in wind and solar energy, while individuals can adopt eco-friendly habits like using public transport.
Conclusion）
总结观点,呼吁行动，避免简单重复。
例句：
- In conclusion, addressing climate change requires global cooperation and immediate action. Only by working together can we ensure a sustainable future for the next generation.
高分技巧
- 使用学术化表达：避免口语化，如用“accelerate”代替“speed up”。
- 逻辑连接词：
- 表因果：As a result, Consequently
- 表对比：However, On the contrary
- 表递进：Furthermore, Moreover
- 多样化句式：穿插被动语态、定语从句等，如：
- The Arctic ice, which is melting at an alarming rate, could disappear by 2030.
模板套用（以议论文为例） *Should governments take stricter measures to combat climate change?*
范文片段：
There is no doubt that climate change poses a severe threat to humanity. Governments must implement stricter policies, such as taxing carbon emissions and subsidizing green energy projects. For instance, countries like Sweden have successfully reduced emissions by 25% through such measures. Individuals also play a role, but without systemic change, progress will remain limited.
常见错误避免
- 跑题：紧扣“气候变化”，勿泛泛讨论环保。
- 语法错误：主谓一致、时态（多用现在完成时/一般现在时）。
- 词汇重复：如多次用“bad”，可替换为“detrimental”或“harmful”。
拓展学习资源
- 纪录片推荐：An Inconvenient Truth（《难以忽视的真相》）
- 权威报告：IPCC（联合国政府间气候变化专门委员会）年度报告
- 词汇工具：剑桥词典“Climate Change”专题词表
引用说明
- 数据来源：NASA官网、IPCC第六次评估报告
- 学术参考：English for Environmental Science (Cambridge University Press)
