话题九： 自然生态与环境保护 · 高频词微语境（中英对照版） 37个核心词汇 · 5篇短文 · 英文+中文对照 · 词频标注 适用于60-80分学生 · 高频词加粗下划线 · 每篇附词频与用法提示 微语境 1 生态系统 · 生物多样性 Every ecosystem on Earth is connected. The natural environment provides us with everything we need to survive. Wildlife and plant species depend on each other for survival. Ecology is the study of how living things interact with their surroundings. Protecting biodiversity is essential for a healthy planet. Conservationists work hard to protect endangered animals and plants from disappearing forever. 地球上的每一个生态系统都是相互联系的。自然环境为我们提供了生存所需的一切。野生动物和植物物种相互依赖才能生存。生态学是研究生物如何与环境相互作用的学科。保护生物多样性对地球的健康至关重要。环保主义者努力保护濒危的动植物，防止它们永远消失。 ★★★★★ 高频必背：ecosystem, environment, wildlife, species, ecology, biodiversity ★★★★☆ 课标新增：biodiversity, species, wildlife, ecology, conservationist, endangered 💡 用法点拨： ecosystem 指"生态系统"；biodiversity 是"生物多样性"；species 单复数同形；conservationist 是"环保主义者"；endangered 常与 species 搭配。 微语境 2 污染 · 气候变化 Pollution is one of the biggest threats to our planet. Air pollution and water pollution harm both humans and animals. Carbon emissions from factories and cars contribute to climate change. Greenhouse gases trap heat in the atmosphere, causing global temperatures to rise. We all need to reduce our carbon footprint. Fossil fuels like coal and oil are major sources of pollution. Solar energy is a clean and renewable alternative that can help us build a sustainable future. 污染是地球面临的最大威胁之一。空气污染和水污染对人和动物都有害。工厂和汽车排放的碳排放物导致了气候变化。温室气体将热量困在大气中，导致全球气温上升。我们都需要减少我们的碳足迹。化石燃料如煤和石油是污染的主要来源。太阳能是一种清洁、可再生的替代能源，可以帮助我们建设可持续的未来。 ★★★★★ 高频必背：pollution, emission, climate, greenhouse, carbon, sustainable, renewable ★★★★☆ 课标新增：fossil, solar 💡 用法点拨： pollution 不可数名词；emission 常用复数 emissions；carbon footprint 是"碳足迹"；sustainable 常与 development 搭配；renewable 常与 energy 搭配。 微语境 3 资源保护 · 回收利用 Conservation of natural resources is everyone's responsibility. We should recycle paper, plastic, and glass to reduce waste. It is also important to reduce our daily consumption. We must preserve forests, oceans, and clean water for future generations. Reuse plastic bags and bottles whenever possible. Degradable materials are better for the environment because they break down naturally. By practicing the three R's—reduce, reuse, and recycle—we can make a real difference. 保护自然资源是每个人的责任。我们应该回收利用纸张、塑料和玻璃来减少浪费。减少日常消耗也很重要。我们必须为后代保护森林、海洋和清洁的水资源。尽可能再利用塑料袋和瓶子。可降解的材料对环境更友好，因为它们可以自然分解。通过践行三个R——减少、再利用和回收利用——我们可以真正做出改变。 ★★★★★ 高频必背：conservation, recycle, reduce, preserve ★★★★☆ 课标新增：reuse, degradable 💡 用法点拨： conservation 是"保护"；reduce 与 reuse、recycle 常并列出现；degradable 指"可降解的"，与 biodegradable 同义；preserve 指"保护/保存"。 微语境 4 栖息地 · 生态威胁 Deforestation destroys the homes of countless animals. Natural disasters like floods and wildfires can also cause great damage to ecosystems. Ecological balance is essential for the survival of all living things. Wetlands and tropical rainforests are among the most important habitats on Earth. Fertile soil is necessary for growing food. Marine life in the oceans is threatened by pollution and overfishing. Migration patterns of birds and fish are changing due to climate change. Understanding ecology helps us protect these vital habitats. 森林砍伐摧毁了无数动物的家园。洪水、野火等自然灾难也会对生态系统造成巨大破坏。生态平衡对所有生物的生存至关重要。湿地和热带雨林是地球上最重要的栖息地之一。肥沃的土壤是种植粮食所必需的。海洋生物受到污染和过度捕捞的威胁。由于气候变化，鸟类和鱼类的迁徙模式正在改变。了解生态学有助于我们保护这些重要的栖息地。 ★★★★★ 高频必背：disaster, ecological ★★★★☆ 课标新增：deforestation, wetland, tropical, fertile, marine, migration 💡 用法点拨： deforestation 是"森林砍伐"；wetland 是"湿地"；tropical 指"热带的"；marine 指"海洋的/海生的"；migration 指"迁徙/迁移"。 微语境 5 课标新增 · 农业与自然现象 Agriculture depends on healthy natural systems. Irrigation is necessary for farming in dry areas. Farmers also raise livestock for food and other products. Dams are built to store water for irrigation and electricity. Sometimes thick fog covers the fields in the early morning. At night, the flame of a campfire can be seen from far away. All these elements remind us of our close connection to the natural world. By protecting the environment, we ensure a better future for both humans and animals. 农业依赖健康的自然系统。灌溉是干旱地区农业所必需的。农民还饲养家畜以获取食物和其他产品。人们修建水坝来储存灌溉用水和发电。有时清晨浓雾覆盖田野。夜晚，篝火的火焰在远处就能看到。所有这些都提醒我们与自然世界的紧密联系。通过保护环境，我们确保人类和动物都能拥有更美好的未来。 ★★★★★ 2025课标新增：irrigation, livestock, dam, fog, flame ★★★★☆ 阅读高频：irrigation, livestock 💡 用法点拨： irrigation 指"灌溉"；livestock 是"家畜/牲畜"（集合名词）；dam 是"水坝/堤坝"；fog 是"雾"；flame 是"火焰"。 本话题37个高频词一览 English 中文 English 中文 ecosystem 生态系统 environment 环境 sustainable 可持续的 renewable 可再生的 pollution 污染 emission 排放 conservation 保护（资源） recycle 回收利用 extinction 灭绝 climate 气候 greenhouse 温室 carbon 碳 deforestation 新 森林砍伐 disaster 灾难 ecological 生态的 degradable 新 可降解的 preserve 保护；保存 reduce 减少 endangered 新 濒危的 wetland 新 湿地 fertile 新 肥沃的；富饶的 marine 新 海洋的；海生的 tropical 新 热带的 migration 新 迁徙；迁移 irrigation 新 灌溉 livestock 新 家畜；牲畜 fossil 新 化石 solar 新 太阳的；太阳能的 biodiversity 新 生物多样性 wildlife 新 野生动物 ecology 新 生态学 species 新 物种 reuse 新 再利用 conservationist 新 环保主义者 dam 新 水坝；堤坝 fog 新 雾 flame 新 火焰 ⬇ 下载 Word 文档 (.doc) 1 学科网（北京）股份有限公司 $ 话题九：自然生态与环境保护 · 高频词微语境（默写版） 37个核心词汇 · 英文填空 · 中文对照 · 词频标注 适用于60-80分学生 · 根据中文提示默写英文 · 每篇附词频与用法提示 微语境 1 生态系统 · 生物多样性 Every __________ on Earth is connected.
