主题理解:保护濒危动物不仅是生态平衡的需要,更是人类文明的责任。这篇托福写作范文将从生态、伦理、科学价值三个维度展开论述,展示如何构建严谨的议论文逻辑。
在托福独立写作中,“保护濒危动物”是经典题目之一。它要求考生在30分钟内完成一篇300词以上的议论文,并展示出清晰的逻辑、丰富的词汇和复杂的句式。下面我们将通过两篇范文来解析如何高效应对此类话题。
英文原文:
The preservation of endangered species is not merely an emotional appeal but a critical necessity for maintaining ecological balance. Firstly, each species plays a unique role in the ecosystem. For instance, bees pollinate plants, which supports agriculture and food production. If bees become extinct, the consequences would be catastrophic. Secondly, from an ethical perspective, humans have a moral obligation to protect other living beings. We should not allow species to vanish due to our irresponsible activities such as deforestation and pollution. Lastly, endangered animals often possess genetic information that could be vital for scientific research. For example, some species have unique immune systems that might help us develop new medicines. Although some argue that conservation efforts are costly, the long-term benefits far outweigh the expenses. In conclusion, protecting endangered species is essential for ecological health, moral responsibility, and scientific progress.
中文翻译:
保护濒危物种不仅仅是一种情感上的呼吁,更是维持生态平衡的关键必需。首先,每个物种在生态系统中都扮演着独特的角色。例如,蜜蜂为植物授粉,这支持了农业和粮食生产。如果蜜蜂灭绝,后果将是灾难性的。其次,从伦理角度来看,人类有道德义务保护其他生物。我们不应该因为自己的不负责任活动(如森林砍伐和污染)而让物种消失。最后,濒危动物通常拥有对科学研究至关重要的遗传信息。例如,一些物种具有独特的免疫系统,可能帮助我们开发新药物。尽管有人认为保护工作成本高昂,但长期收益远远超过支出。总之,保护濒危物种对于生态健康、道德责任和科学进步都至关重要。
| 序号 | 知识点 | 解析 |

| 1 | pollinate plants | 动词短语,意为“为植物授粉”,是生态类话题高频词汇 |
| 2 | moral obligation | 名词短语,意为“道德义务”,常用于伦理论证段落 |
| 3 | far outweigh | 动词短语,“远远超过”,用于对比论证 |
| 4 | not merely... but... | 经典句式结构,“不仅仅是...而是...” |
| 5 | have a ... obligation to | 固定搭配,“有...义务去做” |
| 6 | due to | 介词短语,“由于”,表原因 |
英文原文:
In today's world, the rapid extinction of animal species has become a pressing global issue. There are several compelling reasons why we should dedicate resources to protecting these creatures. Ecologically, every species is part of a complex web of life. The disappearance of one species can trigger a chain reaction, ultimately affecting human survival. For example, the decline in shark populations has led to an increase in smaller fish, which then overgraze on plankton and disrupt the marine ecosystem. Ethically, it is unjustifiable for humans to cause the extinction of other species simply for short-term economic gains. Many endangered animals, such as elephants and tigers, have intrinsic value beyond their economic utility. Scientifically, these species hold keys to understanding evolution and biological adaptation. The genetic diversity found in wild species may provide solutions to future human diseases. Therefore, despite the challenges, we must prioritize conservation efforts to ensure a sustainable future for all species on Earth.
中文翻译:
在当今世界,动物物种的迅速灭绝已成为紧迫的全球问题。我们有几个令人信服的理由应该投入资源保护这些生物。从生态学角度看,每个物种都是复杂生命网络的一部分。一个物种的消失可能引发连锁反应,最终影响人类生存。例如,鲨鱼数量的减少导致小鱼数量增加,后者过度捕食浮游生物并破坏海洋生态系统。从道德角度看,人类仅仅为了短期经济利益而导致其他物种灭绝是不合理的。许多濒危动物,如大象和老虎,具有超越其经济效用的内在价值。从科学角度看,这些物种掌握了理解进化和生物适应的关键。野生物种中发现的遗传多样性可能为未来人类疾病提供解决方案。因此,尽管存在挑战,我们必须优先考虑保护工作,以确保地球上所有物种的可持续未来。
| 序号 | 知识点 | 解析 |
|---|---|---|
| 1 | pressing global issue | 形容词+名词短语,“紧迫的全球问题”,开头段常用 |
