1、选修 Unit 3 单元主题语篇训练.阅读理解ACoral reefs (珊瑚礁) are an integral part of sea life and sustain it by providing shelter and habitat to 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,
2、 the rise in average water temperatures due to climate change has resulted in more frequent and longtime “coral bleaching (珊瑚白化)” events that damage their health, causing fish and other sea species to abandon them.In order to restore this delicate ecosystem, scientists from the U. K. and Australia c
3、onducted a study that involved using loudspeakers underwater near damaged coral reefs to make them sound healthy and attract fish, potentially kickstarting the natural recovery process of coral reefs and their dependent life forms. The location for this experiment was the Great Barrier Reef in the C
4、oral 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 theyr
5、e looking for a place to settle，” said Steve Simpson, study coauthor and a professor at the University of Exeter, U. K.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
6、are crucial for coral reefs to function as healthy ecosystems. Boosting fish population in this way could help to kickstart natural recovery processes, preventing the damage were seeing on many coral reefs around the world，” said lead author, Tim Gordon.语篇解读：由于海水温度的上升，深海珊瑚的生态遭到破坏。科学家通过实验研究发现，在珊瑚礁旁边放
