Question

    A team of scientists says that playing sounds underwater can get fish to return to areas with severely damaged coral reefs(珊瑚礁).In an experiment, they found fish returned after hearing recordings of the sounds like a healthy ocean reef. The research results were reported in Nature Communications.

The scientists placed underwater speakers in areas where coral had been dying in Australia’s northern Great Barrier Reef. They played the sounds over a period of about six weeks in 2017 and studied the results. The team reported that twice as many fish arrived in the areas where the sounds of healthy coral were played. The sounds also led to a 50 percent increase in the number of species present in the area, the researchers found. The researchers noted the importance of having many different kinds of fish return to the area. Different species of fish perform many activities that support the ocean environment and sea life.

Steve Simpson is a professor at the University of Exeter who helped lead the research. He explained, “Healthy coral reefs are remarkably noisy places. They contain the sounds of many kinds of shrimp, fish and other sea creatures. Young fish listen to these sounds when they are looking for a place to settle. Reefs become extremely quiet when they suffer destruction that is usually related to human-caused pollution. Coral damage can drive shrimp and fish away. But the experiment suggested that the use of underwater loudspeakers was an effective way to get young fish to come back.”

Mark Meekan is a fish biologist. He said that the return of the fish is the first step towards seeing major improvements in reef health. “Recovery is underpinned (巩固) by fish that clean the reef and create space for corals to regrow,” he said. University of Bristol professor, Andy Radford, said the underwater sounds are a promising way to fight coral reef damage at the local community level. But he noted that other threats need to be reduced as well. These include climate change, pollution and over fishing.

1.Why can underwater speakers make fish return?

A.Because the fish prefer music around their habitats.

B.Because they play sounds as a healthy reef does.

C.Because the fish know the places with them become better.

D.Because they can drive the natural enemies of fishes away.

2.What effect do different kinds of fish have on the ocean according to the text?

A.Keeping the ocean’s ecological balance. B.Removing the remarkable noises.

C.Preventing the pollution caused by human. D.Driving dangerous creatures away.

3.How does the author prove the significance of this new finding?

A.By quoting different authorities’ words.

B.By comparing the result with another study’s.

C.By offering many statistics.

D.By showing the detailed process of experiments.

4.In which section of a newspaper may this text appear?

A.Education. B.Entertainment.

C.Environment. D.Economy.

【解析】

本文是一篇说明文。讲述了鱼在听到一个健康的珊瑚礁的声音后从返珊瑚礁严重受损的地区。鱼的回归是看到珊瑚礁健康状况有重大改善的第一步，对保持海洋生态系统起着至关重要的作用。

1.细节理解题。根据原文的“they found fish returned after hearing recordings of the sounds like a healthy ocean reef.”（他们发现，在听到与健康珊瑚礁发出的声音录音后，鱼就会返回）。所以为什么水下扬声器能让鱼回来是因为它们发出的声音和健康的珊瑚礁的声音一样。故选B项。

2.推理判断题。根据原文“Different species of fish perform many activities that support the ocean environment and sea life”（不同种类的鱼从事许多支持海洋环境和海洋生物的活动）由此判断出不同鱼类保持着海洋生态的平衡。故选A项。

3.推理判断题。根据原文Mark Meekan is a fish biologist. He said that the return of the fish is the first step towards seeing major improvements in reef health. “Recovery is underpinned (巩固) by fish that clean the reef and create space for corals to regrow,” he said.马克·米肯是澳大利亚海洋科学研究所的鱼类生物学家。他在一份声明中说，这些鱼的回归是看到珊瑚礁健康状况有重大改善的第一步。”复苏的基础是鱼类清理珊瑚礁，为珊瑚礁再生创造空间。根据University of Bristol professor, Andy Radford, said the underwater sounds are a promising way to fight coral reef damage at the local community level. 布里斯托尔大学教授安迪·雷德福德说，水下声音是在当地社区一级对抗珊瑚礁破坏的一种有希望的方法。由此判断出，作者通过引用不同权威的话证明这一新发现的意义。故选A项。

4.推理判断题。讲述了鱼在听到一个健康的珊瑚礁的声音后从返珊瑚礁严重受损的地区。鱼的回归是看到珊瑚礁健康状况有重大改善的第一步，对保持海洋生态系统起着至关重要的作用。由此判断出短文会出现在报纸的环境板块。故选C项。
