TEST (检，练) A healthy coral reef is far from quiet. It buzzes with a symphony of marine life. But as reefs degrade due to bleaching（珊瑚白化）, pollution, and overfishing, they turn silent, driving away fish and other key species that keep the ecosystem functional. To overturn this, a team of UK and Australian scientists led by Tim Gordon tested a sound-based approach at Australia’s Great Barrier Reef. The team placed underwater speakers in severely damaged coral areas. These speakers broadcast recordings of sounds from thriving reefs. Control sites without speakers were set up nearby for comparison. The results, published in Nature, were striking: sound-playing sites attracted twice as many fish as control areas. The number of fish species present also rose by 50%. Returning fish play a vital role in reef recovery,which eat algae that damages coral polyps, clearing space for new growth, while predators keep the food web balanced.Studies by other teams found that healthy reef sounds can also boost coral larval settlement—a key step in reef regrowth. Larvae use sound cues to find suitable habitats, and enriched sounds increase their chance of settling in degraded areas. This dual benefit makes sounds enrichment a promising tool for reef restoration projects worldwide. The scientists stressed that sound alone cannot fully restore a dead reef. It must be paired with other measures, such as reducing local pollution, limiting overfishing, and establishing marine protected areas (MPAs). Climate change, the root cause of widespread bleaching, also needs global action to control rising ocean temperatures. While the method is low-cost and easy to apply, challenges remain. Speakers need regular maintenance and power supply in tough marine environments. Still, the approach offers a glimmer of hope for one of Earth’s most threatened ecosystems. 1. What is the main purpose of the scientists' testing the sound-based approach? A. To collect sounds of different marine species in the Great Barrier Reef B. To address the problem of degraded reefs by attracting key species back C. To prove that healthy reefs are noisier than damaged ones D. To design more advanced underwater speakers for marine research 命题点_______:__________________________________→locate para___________→reason key sentence _________________________________________________________→ choose answer__________ 2. What do we know about the underwater speakers used in the experiment? A.They were placed in both thriving and damaged reef areas B.They played recordings of sounds from healthy coral reefs C.They were powered by solar energy to reduce environmental harm D.They were first invented by Tim Gordon’s research team 命题点_______:__________________________________→locate para___________→reason key sentence _________________________________________________________→ choose answer__________ 3. Why are returning fish important for reef recovery? A. They can directly reduce the rate of coral bleaching caused by climate change B. They help create soundscapes that attract coral larvae to the reef C. They perform roles like eating harmful algae and balancing the food web D. They build new habitats for coral polyps by digging in the seabed 命题点_______:__________________________________→locate para___________→reason key sentence _________________________________________________________→ choose answer__________ 4. What is the author’s attitude towards the sound-based reef restoration project? A. Fully pessimistic about its long-term effects B. Cautiously optimistic despite existing challenges C. Completely doubtful about its practical value D. Unconcerned about its application in real situation 命题点_______:__________________________________→locate para___________→reason key sentence _________________________________________________________→ choose answer__________ Homework  （2022 年全国甲）你校将以六月八日世界海洋日为主题，举办英语征文比赛，请你写一篇短文投稿。内容包括： 海洋的重要性； 保护海洋的倡议。 注意： 词数 80 左右； 短文的题目和首句已为你写好 题目：Our Oceans, Our Responsibility 首句：June 8th was officially named by the UN in 2009 as World Oceans Day. _________________________________________________________________________________________ 学科网（北京）股份有限公司 $
