如何通过气候话题提升托福作文写作能力
托福写作部分对考生的逻辑思维、语言表达和知识储备都有较高要求,而气候话题作为高频考点之一,不仅能帮助考生积累素材,还能锻炼论证能力,掌握气候相关的英语表达和写作技巧,可以让托福作文更具深度和说服力,从而在考试中脱颖而出。
气候话题在托福写作中的重要性
托福独立写作和综合写作常涉及环境、能源、可持续发展等议题,而气候变化是其中的核心内容,ETS(美国教育考试服务中心)倾向于选择具有全球性、争议性的话题,以考察考生的批判性思维和论证能力。
- 独立写作:"Do you agree or disagree that governments should invest more in renewable energy than fossil fuels?"
- 综合写作:阅读材料讨论全球变暖的影响,听力部分可能反驳或补充观点。
熟悉气候话题不仅能帮助考生快速理解题目,还能提供丰富的论据支持,避免写作时无话可说。
积累气候相关的高分词汇和句型
托福作文评分标准(Scoring Rubric)强调词汇多样性(Lexical Resource)和语法准确性(Grammatical Range and Accuracy),以下是气候话题中常用的高分表达:
(1)核心术语
- 气候变化:climate change / global warming
- 温室气体:greenhouse gases (CO₂, methane)
- 可再生能源:renewable energy (solar, wind, hydropower)
- 碳排放:carbon emissions / carbon footprint
- 极端天气:extreme weather events (droughts, hurricanes)
(2)高分句型
- 强调影响:
"The rising sea levels caused by melting glaciers pose a severe threat to coastal cities." - 对比论证:
"While fossil fuels provide immediate energy, renewable sources offer long-term sustainability." - 建议措施:
"Governments should implement stricter regulations to curb industrial pollution."
构建逻辑清晰的论证框架
托福写作要求观点明确、论证充分,以气候话题为例,可以采用以下结构:
(1)开头段(Introduction)
- 背景引入:简要说明气候问题的普遍性。
- 明确立场:直接回答题目问题(同意/不同意)。
- 预告论点:概括主要支持理由。
示例:
"Climate change has become a pressing global issue, sparking debates on energy policies. I firmly believe that governments should prioritize renewable energy over fossil fuels due to environmental benefits, economic advantages, and long-term sustainability."
(2)主体段(Body Paragraphs)
每段围绕一个分论点展开,结合具体例子和数据:
段落1:环境效益
- 论点:可再生能源减少污染。
- 论据:"Solar and wind power produce minimal carbon emissions compared to coal, which accounts for 40% of global CO₂ output (IEA, 2023)."
段落2:经济效益
- 论点:绿色产业创造就业机会。
- 论据:"The renewable energy sector employed 12 million people worldwide in 2022, a figure expected to double by 2030 (IRENA report)."
段落3:可持续性
- 论点:化石燃料储量有限。
- 论据:"Oil reserves may be depleted within 50 years, whereas sunlight and wind are inexhaustible."
(3)结尾段(Conclusion)
- 重申立场:用不同句式强调观点。
- 升华主题:呼吁行动或展望未来。
示例:
"In conclusion, shifting to renewable energy is not merely an environmental necessity but also a strategic economic decision. By investing in clean energy today, we can ensure a healthier planet for future generations."
避免常见错误
(1)空洞的泛泛而谈
- 错误:"Pollution is bad for the environment."
- 改进:"Air pollution from vehicle emissions contributes to 7 million premature deaths annually (WHO data)."
(2)中式英语表达
- 错误:"People should protect environment."
- 正确:"Individuals must take action to preserve the environment."
(3)逻辑跳跃
- 错误:"Renewable energy is good, so we should use it."
- 改进:"Renewable energy reduces reliance on finite resources, making it a viable long-term solution."
