2025-2026学年上学期八年级英语知识点梳理与巩固(译林版2024) Unit 7 The natural world书面表达 必备知识清单 单元写作指导 一、主题阐述 在我们生活的地球上,存在着各种各样的生态系统,如森林生态系统、海洋生态系统、湿地生态系统等。它们对于维持地球的生态平衡、提供人类生存所需的资源以及保障生物多样性都起着至关重要的作用。然而,如今许多生态系统正面临着严重的威胁,如环境污染、过度开发、气候变化等。本单元写作要求我们选择一个生态系统,并撰写一份提案,呼吁人们保护它。通过这样的写作,不仅能锻炼我们的英语表达能力,更能增强我们对生态环境保护的意识,并激发他人的环保行动。 二、写作分析 (一)主题内涵 本次写作主题旨在让我们深入了解某一生态系统的重要性,认识到其面临的问题,并通过合理的提案,向人们传达保护该生态系统的紧迫性和必要性,鼓励大家采取实际行动来保护生态环境。 (二)审题要点 明确生态系统选择:从众多生态系统中挑选一个,确保自己对其有一定了解,能够阐述清楚其特点、作用及面临的问题。 理解提案要求:写作内容要围绕如何保护所选生态系统展开,提出切实可行的建议,而不是单纯描述生态系统本身。 注意语言表达:运用恰当的词汇和语法结构,清晰、准确地表达自己的观点,同时注意语言的连贯性和逻辑性。 (三)写作核心 突出生态系统的重要性:详细说明所选生态系统对地球、生物以及人类生活的重要意义,让读者深刻认识到保护它的价值。 清晰阐述问题:指出该生态系统目前面临的主要问题,如森林生态系统的乱砍滥伐、海洋生态系统的塑料污染等,并分析问题产生的原因和可能带来的后果。 提出有效保护建议:根据存在的问题,提出具体、可操作的保护措施,如制定相关法律法规、加强环保宣传教育、推广可持续发展的生活方式等。 三、写作框架 (一)结构框架 1.开头(Introduction):引出所选生态系统,简要介绍其基本情况,并说明写作目的是呼吁人们保护它。 例如: The rainforest, known as the “lungs of the earth”, is a vital ecosystem. However, it is now facing serious threats. Therefore, I am writing this proposal to call on people to protect it. 2.主体(Body): 生态系统重要性(Importance of the ecosystem):分点阐述该生态系统的重要作用,如提供氧气、维持生物多样性、调节气候等。 例如:Firstly, the rainforest plays a crucial role in producing oxygen. It is estimated that over 20% of the world’s oxygen is generated by the Amazon rainforest alone. Secondly, it is home to countless species of plants and animals. Many of them are found nowhere else on earth. 面临的问题(Problems it faces):详细描述生态系统面临的各种问题,以及这些问题对生态系统和人类的影响。 例如:Unfortunately, the rainforest is being destroyed at an alarming rate. Deforestation for agriculture, logging, and urban expansion is reducing its area day by day. As a result, many species are losing their habitats and facing extinction. 保护建议(Protection suggestions):针对上述问题,提出一系列具体的保护建议。 例如:To protect the rainforest, we should first enforce strict laws against illegal logging and deforestation. Secondly, we need to promote sustainable agriculture and forestry practices. Thirdly, raising public awareness about the importance of the rainforest through education and media campaigns is also essential. 3.结尾(Conclusion):总结保护该生态系统的重要性和紧迫性,再次呼吁人们行动起来,共同为保护生态环境贡献力量。 例如: In conclusion, the rainforest is of great significance to our planet and all living beings. It is our responsibility to take immediate action to protect it. Let us work together to ensure a sustainable future for ourselves and for generations to come. 四、词汇句式 (一)相关词汇 1.生态系统相关 ecosystem(生态系统) rainforest(雨林) ocean(海洋) wetland(湿地) desert(沙漠) grassland(草原) forest(森林) jungle(丛林) coral reef(珊瑚礁) mangrove(红树林) 2.生态系统组成部分 plant(植物) tree(树) flower(花) grass(草) animal(动物) bird(鸟) fish(鱼) insect(昆虫) mammal(哺乳动物) reptile(爬行动物) amphibian(两栖动物) 3.环境问题 pollution(污染) deforestation(砍伐森林) overfishing(过度捕捞) climate change(气候变化) global warming(全球变暖) habitat destruction(栖息地破坏) soil erosion(水土流失) air pollution(空气污染) water pollution(水污染) plastic waste(塑料垃圾) 4.保护措施 protect(保护) conserve(保护;保存) preserve(保护;维护) save(拯救) recycle(回收利用) reduce(减少) reuse(重复使用) plant trees(植树) ban(禁止) enforce laws(执行法律) 5.其他相关 important(重要的) vital(至关重要的) significant(有重大意义的) necessary(必要的) responsibility(责任) action(行动) awareness(意识) sustainable(可持续的) future(未来) (二)相关句式 引出生态系统及重要性: The [ecosystem name] is one of the most important ecosystems on earth.([生态系统名称] 是地球上最重要的生态系统之一。) [Ecosystem name], known as the “[nickname]”, plays a vital role in maintaining the balance of nature.([生态系统名称],被称为 “[昵称]”,在维持自然平衡方面起着至关重要的作用。) It is well - known that the [ecosystem name] provides many benefits to humans and other living beings.(众所周知,[生态系统名称] 为人类和其他生物提供了许多益处。) 例句:The ocean is one of the most important ecosystems on earth.

It provides us with abundant food, regulates the climate, and is home to countless marine creatures. However, the ocean is now in great danger. Plastic pollution is a huge problem. Every year, millions of tons of plastic waste end up in the ocean, harming marine life. Overfishing is also a serious issue. Many fish species are on the verge of extinction. To protect the ocean, we should take immediate action. Firstly, we should reduce the use of single - use plastics and recycle plastic products. Secondly, the government should enforce strict laws against overfishing. Thirdly, we can organize volunteer activities to clean up the beaches. Let us work together to protect the ocean and ensure a better future for ourselves and for the generations to come. 【范文分析】 开头: 通过介绍海洋覆盖地球表面的比例,引出海洋是一个重要的生态系统,并阐述其重要作用,如提供食物、调节气候和为众多海洋生物提供栖息地,清晰地引出主题。 主体: 问题阐述:指出海洋面临的两大主要问题,即塑料污染和过度捕捞,并简单描述了问题的严重性,如大量塑料垃圾进入海洋危害海洋生物,过度捕捞导致许多鱼类濒临灭绝。 保护建议:针对问题提出了三条具体建议,包括减少一次性塑料制品使用和回收塑料、政府加强对过度捕捞的法律管控以及组织志愿者清理海滩,建议具有可操作性。 结尾: 呼吁大家共同努力保护海洋,以确保为自己和后代创造一个更美好的未来,再次强调主题并升华了文章主旨。 六、优化策略 (一)内容方面 深入研究生态系统:在写作前,通过查阅书籍、资料、观看纪录片等方式,更全面、深入地了解所选生态系统的特点、功能、面临的问题及相关数据,使文章内容更丰富、准确、有说服力。例如,在描述海洋生态系统时,可以提及具体的受威胁鱼类物种数量以及塑料垃圾在海洋中的分布数据等。 增加具体事例:为了使提出的保护建议更具可信度,可以结合一些实际的成功案例。比如在提到保护森林生态系统时,可以举例说明某个地区通过实施可持续林业政策,森林覆盖率得以提高,生态环境得到改善。 (二)语言方面 运用高级词汇和短语:在保证用词准确的基础上,适当使用一些高级词汇和短语来提升文章的档次。例如,用 “preserve” 替换 “protect”,用 “be on the verge of” 替换 “be close to” 等。 多样化句式结构:避免文章中句式过于单一,可适当运用复合句、并列句、倒装句等。如在描述生态系统重要性时,可以使用强调句 “It is the rainforest that provides us with fresh air and rich biodiversity.”;在阐述问题原因时,可以用 “Not only does overfishing lead to the decline of fish populations, but it also disrupts the entire marine ecosystem.” 这样的倒装句。 (三)逻辑方面 合理使用连接词和过渡句:在文章中恰当使用连接词(如 however, therefore, firstly, secondly 等)和过渡句,使文章段落之间、句子之间的逻辑关系更清晰,行文更流畅。例如,在从阐述生态系统重要性过渡到面临的问题时,可以使用 “However, despite its great significance, the [ecosystem name] is now facing a series of challenges.” 这样的过渡句。 检查文章逻辑性:完成写作后,仔细检查文章的逻辑结构,确保各部分内容之间紧密关联,保护建议是针对所提出的问题而制定的,整个文章条理清晰、层次分明。 综合实战演练 1.你校英语社团计划开展“守护长江,绿色未来”主题活动。请根据以下提示,以社团负责人李华的身份写一篇英文倡议书,呼吁全校师生参与环保行动。 现状与挑战:江面塑料污染、过度捕捞破坏生态 (ecosystem) 等问题。 具体倡议:1. 个人行动:减少塑料制品使用,……; 2. 校园行动:两岸植树,……; 3. 科技助力:AI智能监测,……。 要求:1. 词数:不少于90词,开头和结尾已写好,不计入总词数; 2. 倡议书内容必须包括以上要点,可适当发挥; 3. 段落分明,语意通顺,书写规范; 4. 不得出现真实姓名、校名及地名等信息。 Dear teachers and classmates, The Yangtze River, our mother river, is facing ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ Remember: every little thing we do brings us closer to a green future.

Dear teachers and classmates, The Yangtze River, our mother river, is facing serious challenges. Plastic pollution is everywhere on the river surface, and overfishing has broken the balance of its ecosystem. It’s time for us to take action to protect it. First, let’s start with personal actions. We should reduce the use of plastic products, such as bringing reusable bags when shopping and refusing disposable tableware. Every small step can cut down plastic waste entering the river. Second, we can organize campus activities. Planting trees along both sides of the Yangtze River can prevent soil erosion and provide a better living environment for aquatic organisms. We can also hold river-cleaning activities on weekends to collect rubbish by the river. Third, we can use technology to help. With AI intelligent monitoring systems, we can track the situation of plastic pollution and illegal fishing in real time. This can help relevant departments take timely measures to stop harmful behaviors. Remember: every little thing we do brings us closer to a green future. Come and join us today!

One Earth, One Home The earth is home to both humans and animals. But today wild animals are facing serious problems because of humans. Many animals are losing their homes as forests are cut down. What’s worse, people kill wild animals for their fur or bones. So many wild animals are in danger. We need to protect wild animals because they are important to nature. They help keep the environment healthy. Without animals, our world would be out of balance. As students, we can do a lot to help. First, we can learn and tell others about animal protection. Second, we should avoid buying products made from animals. Finally, we can save energy and reduce waste to keep the environment clean. Let’s act together to make a more beautiful home for us humans and animals as well.

Some plants can be made into medicine and clothing. Second, plants are also important for animals. Many animals live in the forest and they eat the fruit from plants and trees. Third, trees and other plants help clean the air, so we can breathe the fresh air every day.

Dear teachers and fellow students, As we all know, the number of wild animals is becoming smaller and smaller in our country. Some of them are even in danger. So many people kill wild animals for their fur and meat. What’s worse, villages and farms are taking away the land and forests of wild animals. Animals are our friends. When people and animals live in harmony, nature stays balanced and our world becomes more colorful.

Animals and trees are in great danger. Now many people kill animals for food and a large number of animals are hunted for money, such as lions, tigers, snakes and so on. I think people should not be allowed to hunt and kill animals. And it is a good idea to protect the homes of animals. What’s more, many trees are cut down every year and there are often forest fires, which leads to the decrease of the number of trees. So I think it’s time to take measures. We should plant as many trees as possible. Besides, we should not use throwaway chopsticks and save paper. Let’s work together to keep the balance between nature and humans.

A low-carbon life helps reduce the emission of carbon dioxide and protects our planet. It is good for our environment. Here are some ways to live a low-carbon life. First, choose green transportation. We can take buses or subways instead of driving cars when going far. Second, reduce the use of plastic products. Third, save energy.

As middle school students, we can make a difference with small actions. First of all, it’s useful to reuse things in daily life. We can reuse waste by using both sides of the paper and reusing things like water bottles, bags and so on. Secondly, we are supposed to save energy.

Here are several reasons for this. Firstly, forests provide a home for countless plants and animals, maintaining biodiversity. For example, birds, insects, and various tree species depend on forests to survive. Secondly, forests help keep the air clean by absorbing harmful gases like carbon dioxide and releasing oxygen through photosynthesis. This process not only freshens the air but also reduces pollution. Additionally, forests protect soil from erosion. Tree roots hold the soil firmly, preventing rainwater from washing it away, which is essential for agriculture and avoiding natural disasters like landslides. Lastly, forests produce a large amount of oxygen, which is vital for all living beings to breathe. In conclusion, forests play a key role in balancing the ecosystem. We should take action to protect them by planting more trees and reducing deforestation. Let’s work together to ensure forests continue to benefit our planet!

It provides us with abundant food, regulates the climate, and is home to countless marine creatures. However, the ocean is now in great danger. Plastic pollution is a huge problem. Every year, millions of tons of plastic waste end up in the ocean, harming marine life. Overfishing is also a serious issue. Many fish species are on the verge of extinction. To protect the ocean, we should take immediate action. Firstly, we should reduce the use of single - use plastics and recycle plastic products. Secondly, the government should enforce strict laws against overfishing. Thirdly, we can organize volunteer activities to clean up the beaches. Let us work together to protect the ocean and ensure a better future for ourselves and for the generations to come. 【范文分析】 开头: 通过介绍海洋覆盖地球表面的比例,引出海洋是一个重要的生态系统,并阐述其重要作用,如提供食物、调节气候和为众多海洋生物提供栖息地,清晰地引出主题。 主体: 问题阐述:指出海洋面临的两大主要问题,即塑料污染和过度捕捞,并简单描述了问题的严重性,如大量塑料垃圾进入海洋危害海洋生物,过度捕捞导致许多鱼类濒临灭绝。 保护建议:针对问题提出了三条具体建议,包括减少一次性塑料制品使用和回收塑料、政府加强对过度捕捞的法律管控以及组织志愿者清理海滩,建议具有可操作性。 结尾: 呼吁大家共同努力保护海洋,以确保为自己和后代创造一个更美好的未来,再次强调主题并升华了文章主旨。 六、优化策略 (一)内容方面 深入研究生态系统:在写作前,通过查阅书籍、资料、观看纪录片等方式,更全面、深入地了解所选生态系统的特点、功能、面临的问题及相关数据,使文章内容更丰富、准确、有说服力。例如,在描述海洋生态系统时,可以提及具体的受威胁鱼类物种数量以及塑料垃圾在海洋中的分布数据等。 增加具体事例:为了使提出的保护建议更具可信度,可以结合一些实际的成功案例。比如在提到保护森林生态系统时,可以举例说明某个地区通过实施可持续林业政策,森林覆盖率得以提高,生态环境得到改善。 (二)语言方面 运用高级词汇和短语:在保证用词准确的基础上,适当使用一些高级词汇和短语来提升文章的档次。例如,用 “preserve” 替换 “protect”,用 “be on the verge of” 替换 “be close to” 等。 多样化句式结构:避免文章中句式过于单一,可适当运用复合句、并列句、倒装句等。如在描述生态系统重要性时,可以使用强调句 “It is the rainforest that provides us with fresh air and rich biodiversity.”;在阐述问题原因时,可以用 “Not only does overfishing lead to the decline of fish populations, but it also disrupts the entire marine ecosystem.” 这样的倒装句。 (三)逻辑方面 合理使用连接词和过渡句:在文章中恰当使用连接词(如 however, therefore, firstly, secondly 等)和过渡句,使文章段落之间、句子之间的逻辑关系更清晰,行文更流畅。例如,在从阐述生态系统重要性过渡到面临的问题时,可以使用 “However, despite its great significance, the [ecosystem name] is now facing a series of challenges.” 这样的过渡句。 检查文章逻辑性:完成写作后,仔细检查文章的逻辑结构,确保各部分内容之间紧密关联,保护建议是针对所提出的问题而制定的,整个文章条理清晰、层次分明。 综合实战演练 1.你校英语社团计划开展“守护长江,绿色未来”主题活动。请根据以下提示,以社团负责人李华的身份写一篇英文倡议书,呼吁全校师生参与环保行动。 现状与挑战:江面塑料污染、过度捕捞破坏生态 (ecosystem) 等问题。 具体倡议:1. 个人行动:减少塑料制品使用,……; 2. 校园行动:两岸植树,……; 3. 科技助力:AI智能监测,……。 要求:1. 词数:不少于90词,开头和结尾已写好,不计入总词数; 2. 倡议书内容必须包括以上要点,可适当发挥; 3. 段落分明,语意通顺,书写规范; 4. 不得出现真实姓名、校名及地名等信息。 Dear teachers and classmates, The Yangtze River, our mother river, is facing ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ Remember: every little thing we do brings us closer to a green future.
