UNIT 1 课时检测(三) Grammar and usage Ⅰ.阅读理解 Coral reefs are an integral part of sea life and sustain it by providing shelter and habitat for various organisms.They also supply and recycle nutrients as well as enable a growing fish population, along with other species, for a healthy and diverse ecosystem.However, the rise in average water temperatures due to climate change has resulted in more frequent and long－time “coral bleaching (白化现象)” events that damage their health, causing fish and other sea species to abandon them. In order to restore this delicate ecosystem, scientists from the UK and Australia conducted a study that involved using loudspeakers underwater near damaged coral reefs to make them sound healthy and attract fish, potentially kick－starting the natural recovery process of coral reefs and their dependent life forms.The location for this experiment was the Great Barrier Reef in the Coral Sea, found alongside the east coast of Queensland, Australia.The site is noted to have the largest coral reef system in the world. “Healthy coral reefs are remarkably noisy places — the crackle of snapping shrimp and the whoops and grunts of fish.Young fish concentrate on these sounds when they're looking for a place to settle，” said Steve Simpson, study co－author and a professor at the University of Exeter, UK. By using loudspeakers to copy such sounds, parts of dead coral reefs were found to attract twice as many fish, compared to places where no sounds were played.“These returning fish are crucial for coral reefs to function as healthy ecosystems.Boosting fish populations in this way could help to kick－start natural recovery processes, preventing the damage we're seeing on many coral reefs around the world，” said lead author, Tim Gordon. 语篇解读：本文是一篇说明文。气候变暖、海水温度上升引起了珊瑚礁的白化现象。为了恢复生态，科学家采用了新方法——通过播放某些音乐以吸引鱼来恢复珊瑚礁，希望借助它们来恢复生态系统。这一方法已经初见成效。 1．What causes the phenomenon of coral bleaching?
