2026年高中英语外刊精练 拯救珊瑚礁：海洋生态的希望 Coral reefs take up only a small part of the ocean floor, but they support the richest variety of sea life on earth. Quite a quarter of ocean species depend on these reefs for survival. Besides, they bring great benefits for human societies: they shield coastlines from waves, create chances for tourism and support fishing industries. However, by the end of the 20th century, human activities such as overfishing, pollution and ocean damage, together with frequent illnesses among corals, had reduced coral coverage to half of its original level. Nowadays, global ocean heating makes this environmental trouble far worse. Some scientists warn that coral reefs have reached a critical turning point. Once crossed, most warmwater corals may disappear, and the damage can hardly be repaired. Much of this worrying judgment comes from a common research standard. It judges coral heat stress by measuring how strong ocean heat waves are and how long they last. Judgments based on this standard suggest that by the end of the 21st century, corals will face deadly heat influences every single year, leaving little room for them to recover. Still, recent studies offer a more hopeful view. The old research standard supposes corals cannot get used to higher ocean temperatures. Yet collected facts show corals can now survive heat conditions that would have destroyed them fifty years ago. Using ecological models that take coral’s slow change over time into account, scientists point out that if global temperature rise is limited within 2℃ — the goal of the Paris Agreement — coral reefs are likely to recover during the second half of this century. Therefore, chances for survival still exist if we can avoid the worstcase warming situations. Several practical actions can be taken to give reefs a better chance. At local levels, cutting humancaused pressure produces good results. For example, reasonable fishing rules protect certain kinds of fish that keep harmful water plants under control. Reducing pollution carried from land also helps damaged corals recover. New technical methods can also offer help, though it remains hard to put them into wide use. These local efforts and new techniques can win valuable time. All the same, scientific research points to one truth: the longlasting way to protect coral reefs is to cut greenhouse gas release and reach netzero emissions. The sooner we achieve this goal, the better chance we have to save these valuable ocean living systems. 一、阅读理解 1.What makes the coralreef crisis become worse at present? A．Physical damage. B．Pollution. C．Ocean warming. D．Overfishing. 2.What is the function of the common research standard mentioned in Paragraph 2? A．To judge heat stress that coral reefs suffer. B．To record how often ocean heatwaves happen. C．To work out the time for sea creatures to recover. D．To find out different causes of world climate change. 3.What is the longterm solution to save coral reefs? A．Signing the Paris Agreement. B．Building more ecological research models. C．Keeping global temperature exactly at 2℃. D．Achieving netzero greenhousegas emissions. 4.Which of the following is the best title for the text? A．Protecting Reefs: Power of Local Action B．Saving Coral Reefs: Path to Survival C．Research Standards: Signs of Ocean Heating D．Coral Reefs: Gifts from the Ocean to Humans 二、七选五 Coral reefs belong to the most valuable living systems in the ocean. 1 However, human activities and climate change have put them in great danger. Some scientists fear that reefs have reached an unrecoverable turning point. Scientists have set up a research standard to study ocean heat waves. 2 Studies based on it warn that corals may meet deadly heat every year before 2100 with little possibility to recover. 3 Facts show corals have developed some ability to deal with higher temperatures. Ecological models suggest reefs may get well again in the late 21st century if global warming is kept within 2℃. So hope is not totally gone if we prevent the most serious warming. We can carry out local and technical work to buy time for coral reefs. 4 Besides, new protective technology is available, though it cannot be widely used for the moment. Even so, these ways cannot solve the problem completely. 5 Only netzero emissions can offer longterm protection for coral reefs. A. Yet new studies bring more hopeful opinions. B. Local work includes proper fishing rules and pollution reduction. C. They support large numbers of sea creatures and benefit human beings. D. It is used to measure the heat pressure received by coral reefs. E. It has solved most of the environmental problems threatening corals. F. Governments should build more underwater labs for oceanrelated research. G. The real root of protection lies in cutting greenhousegas release. 三、阅读表达 1.What is the research standard used for? (No more than 13 words) 2.What is the longlasting way to protect coral reefs? (No more than14 words) 四、读后续写 Wang Hua took part in a summer fieldstudy program about ocean protection. During the trip, he got a close look at coral reefs. Shocked by the sight of pale, dying corals, he learned about the serious challenges coral reefs were facing. Scientists told him that local protective measures could buy time for corals, but the fundamental solution lay in cutting greenhousegas emissions to reach netzero. Back home, Wang Hua could not get the scene of dying corals out of his mind. He wanted to make small efforts to raise public awareness of coralreef protection among his classmates. Yet he wondered whether his small actions would make any real difference. Paragraph 1：The next week, Wang Hua organized a small sharing activity in his class. Paragraph 2：As more students joined in, the influence of their activity spread further. 2026年高中英语外刊精练 参考答案 一、阅读理解 1.C 解析：细节理解。第一段说明海洋变暖让珊瑚礁危机进一步恶化。A、B、D 是二十世纪后期造成珊瑚退化的旧因素，并非当下加剧危机的原因。 2.A 解析：细节理解。第二段的研究标准通过测量海洋热浪强度与持续时间，用来评估珊瑚礁承受的热压力。B、C、D 不属于该标准的作用。 3.D 解析：细节理解。文末点明：实现温室气体净零排放才是保护珊瑚礁长久可行的方案。A 签署协议只是确立目标；B 生态模型只是研究工具；C 概念错误，是升温控制在 2℃以内，不是固定气温为 2℃。 4.B 解析：主旨大意。全文介绍珊瑚礁面临危机，对比不同研究结论，从地方措施到根本减排方案，探讨拯救珊瑚礁的生存之路。A 只覆盖局部地方举措；C 只涉及文中研究指标；D 只讲珊瑚礁的价值，不能概括全文。 二、七选五 1.C 承接，介绍珊瑚礁的生态与经济价值。 2.D 解释该研究标准的用途，测量珊瑚礁承受的热压力。 3.A 过渡转折，引出新研究带来的乐观观点。 4.B 列举地方层面的保护措施。 5.G 点明根本解决途径：削减温室气体排放。。 三、阅读表达 1.To judge heat stress on coral reefs. 2.To achieve netzero greenhousegas emissions. 四、读后续写 Paragraph 1：The next week, Wang Hua organized a small sharing activity in his class. He showed photos of fading corals he had taken in the field trip. He told his classmates about the coralreef crisis. He explained that local protection helped win time, but cutting greenhousegas emissions was the key. Some classmates were greatly shocked by the serious situation and began to think about their own daily carbonsaving choices. Paragraph 2：As more students joined in, the influence of their activity spread further. They put up posters around the campus and called on schoolmates to live a lowcarbon life. Small actions such as saving electricity spread among students. Wang Hua realized individual efforts counted. Though teenagers could not solve the big problem alone, public awareness built by small moves would push people to work for netzero emissions and save coral reefs. 总 结 重点单词 1. variety n. 多样性 2. shield v. 保护，防护 3. original adj. 原来的，最初的 4. critical adj. 关键的 5. recover v. 恢复，复原 6. suppose v. 假定，认为 7. survive v. 存活，幸存 8. ecological adj. 生态的 9. practical adj. 实际的，实用的 10. control v.&n. 控制，抑制 11. emission n. 排放 12. valuable adj. 宝贵的 重点短语 1. take up 占据（空间） 2. depend on 依靠，依赖 3. reduce … to … 把…… 削减至 4. turning point 转折点 5. take … into account 把…… 考虑在内 6. put … into wide use 大规模推广使用 7. all the same 尽管如此 8. netzero emissions 净零排放 参考译文 珊瑚礁虽然只占据海床的一小部分，却孕育着地球上种类最为丰富的海洋生物。将近四分之一的海洋物种依靠珊瑚礁得以生存。此外，它们也给人类社会带来巨大益处：保护海岸免受海浪侵袭，创造旅游发展机遇，同时支撑渔业发展。然而到 20 世纪末，过度捕捞、污染、海洋破坏等人类活动，再加上珊瑚频繁爆发病害，使得珊瑚覆盖率下降到原有水平的一半。如今，全球海洋变暖让这一环境问题变得愈发严峻。一些科学家警示，珊瑚礁已经来到关键转折点。一旦越过这个临界点，大部分温水珊瑚就可能消失，造成的破坏几乎无法修复。 这种令人担忧的判断，很大程度上来自一项通用的研究标准。该标准通过测量海洋热浪的强度与持续时长，评估珊瑚承受的热压力。依据这一标准做出的预测表明，到 21 世纪末，珊瑚每年都将遭遇致命的高温影响，几乎没有恢复的余地。 不过，近期的研究带来了更为乐观的看法。这套旧的研究标准假定珊瑚无法适应不断升高的海水温度。但收集到的实际证据显示，如今的珊瑚已经能够承受五十年前足以将它们摧毁的高温环境。科学家运用把珊瑚长期缓慢演化纳入考量的生态模型指出：如果全球升温幅度控制在《巴黎协定》设定的 2℃目标以内，珊瑚礁就有望在本世纪下半叶逐步恢复。因此，只要我们能够避免最极端的变暖情景，珊瑚礁就仍有生存的希望。 我们可以采取多项切实举措，为珊瑚礁争取生存机会。在地方层面，减少人为造成的环境压力效果显著。例如，合理的渔业管理规定可以保护部分鱼类，这些鱼类能够抑制有害水生植物的泛滥；减少陆地输入的污染，同样有助于受损珊瑚实现自我修复。新技术手段也能够提供帮助，但想要大规模推广应用依旧困难重重。这些地方层面的努力与新技术可以争取宝贵的缓冲时间。尽管如此，科研揭示了一个事实：保护珊瑚礁长久可行的办法是削减温室气体排放，实现净零排放。我们越早达成这一目标，拯救这些珍贵海洋生态系统的胜算就越大。 学科网（北京）股份有限公司 $
