The loss of natural habitats is one of the greatest threats to wildlife around the world. To address this problem, governments have established nature reserves where scientists can observe animals in their natural environment. Thanks to these efforts, some endangered populations have begun to recover. However, human activities continue to reduce available living space for animals. People must become aware of the urgency of wildlife protection. As the saying goes, we do not own the earth — we only borrow it from future generations. The good news is that animals have a remarkable ability to adapt to changing environments. By taking effective measures, we can help more species survive and prevent them from joining the list of extinct creatures that once walked this planet. 【中文译文】（括号内为英文原词） 每天，越来越多的物种（species）面临灭绝（extinct）的危险。自然栖息地（habitats）的丧失是全球野生动物面临的最大威胁（threats）之一。 为了应对这个问题，政府建立了自然保护区（reserves），科学家可以在那里观察（observe）自然环境中的动物。得益于这些努力，一些濒危种群已经开始恢复（recover）。 然而，人类活动继续减少（reduce）动物可利用的生存空间。人们必须意识到（aware）保护野生动物的紧迫性。俗话说得好：地球不是我们从祖先那里继承的，而是我们从子孙那里借来的。 好消息是，动物有非凡的能力去适应（adapt）不断变化的环境。通过采取有效的措施，我们可以帮助更多物种（species）存活下来，阻止它们加入曾经生活在这个星球上的已灭绝（extinct）生物的行列。 💡 语境串联记忆线索：物种面临灭绝 → 栖息地丧失是威胁 → 建立自然保护区观察 → 种群开始恢复 → 人类活动减少空间 → 必须意识到紧迫性 → 动物适应环境 → 帮助物种生存 记忆链：species → extinct → habitat → threat → reserve → observe → recover → reduce → aware → adapt Part 2 知识点列表 序号

One effective way to protect wildlife is setting up nature reserves. 37. ____________________ In these protected areas, scientists can observe animals closely, study their behaviour, and take measures to help populations recover from past threats. Public awareness also plays a key role in wildlife protection. 38. ____________________ Once people understand the serious consequences of species extinction, they are more likely to support conservation efforts and reduce activities that threaten animal habitats. Some animals have shown a remarkable ability to adapt to changing conditions. 39. ____________________ For instance, certain bird species have adjusted their migration patterns in response to climate change, giving scientists hope that not all is lost. Still, the situation remains serious. 40. ____________________ Without immediate and effective action, many of the species we know today may disappear forever, leaving future generations with nothing but pictures and stories of what once walked the earth. A. When people become aware of the problem, they often change their behaviour for the better. B. These reserves provide safe spaces where animals can live and breed without human interference. C. This is not a distant problem — it is happening right now, before our very eyes. D. Scientists estimate that the current extinction rate is 1,000 times higher than the natural background rate. E. However, not all species are able to adjust quickly enough to survive the rapid changes. F. Many governments have invested heavily in wildlife protection programs over the past decade. G. The key is to act now rather than wait until it is too late to reverse the damage. 【答案】 36. C 37. B 38. A 39. E 40. G 【逐题解析】 36. C — 第一段说"每天数十种物种灭绝，速度惊人"，C项"这不是遥远的问题——它正在我们眼前发生"紧承上文，以"this"指代物种灭绝现象，引出后文对原因的具体说明。 37. B — 第二段首句提出"建立自然保护区是保护野生动物的有效方法"，B项"这些保护区提供安全空间"以"these reserves"直接呼应上文nature reserves，后文描述科学家在保护区中的观察工作。 38. A — 第三段主题为"公众意识的关键作用"，A项"当人们意识到问题，通常会改变行为"直接承接上文，后文进一步解释"一旦人们理解了物种灭绝的严重后果……"。 39. E — 第四段首句"一些动物展示了非凡的适应能力"，E项"然而，并非所有物种都能快速适应"以However转折，与上文形成对比，后文以"某些鸟类调整了迁徙模式"例证适应成功的一面。 40. G — 第五段首句"情况依然严峻"，G项"关键是现在就行动，而不是等到为时已晚"是对全文的总结呼吁，与后文"没有立即有效的行动，许多物种将永远消失"紧密呼应。 【干扰项分析】 D项"科学家估计当前灭绝速率是自然背景速率的1000倍"虽然数据与主题相关，但作为独立陈述，与任何段落的上下文都无法形成紧密的逻辑衔接。 F项"许多政府在过去十年大力投资野生动物保护项目"是泛泛之谈，文章各段并未专门讨论政府投资的具体案例，无法与任何段落形成语篇衔接。 Part 8 复现知识点 — 英译汉 请根据英文写出对应汉语释义： 乐思英语 ·高考高频知识点 10 学科网（北京）股份有限公司 1. species — __________ 2. extinct — __________ 3. habitat — __________ 4. reserve — __________ 5. observe — __________ 6. recover — __________ 7. reduce — __________ 8. threat — __________ 9. aware — __________ 10. adapt — __________ 11. extinction — __________ 12. reservation — __________ 13. observation — __________ 14. recovery — __________ 15. reduction — __________ 16. threaten — __________ 17. awareness — __________ 18. adaptation — __________ 19. endangered (adj.) — __________ 20. reserve (v.) — __________ 【参考答案】 1. 物种（单复数同形） 2. 已灭绝的（形容词） 3.（动植物的）栖息地；生活环境 4. 保护区；储藏(量) / 预订；保留 5. 观察；遵守；庆祝（一词多义） 6. 恢复；康复；找回 7. 减少；使沦为；迫使（熟词生义） 8. 威胁（名词） 9. 知道的；意识到的（be aware of） 10. 适应；改编 11. 灭绝（名词） 12. 预订；保留（名词） 13. 观察；遵守（名词） 14. 恢复；康复（名词） 15. 减少；缩减（名词） 16. 威胁；危及（动词） 17. 意识；认识（名词） 18. 适应；改编本（名词） 19. 濒危的（形容词） 20. 预订；保留（动词/熟词生义） Part 9 写作运用 — 词汇升级 同义转换：用本专题词汇替换下面句中的普通词，提升写作表达： 1.
