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, the rise in average water temperatures due to climate change has resulted in more frequent and longtime “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 placesthe crackle of snapping shrimp and the whoops and grunts of fish. Young fish concentrate on these sounds when theyre 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 were seeing on many coral reefs around the world，” said lead author, Tim Gordon.文章大意：本文是一篇说明文。由于气候变暖，海水温度上升，引起了珊瑚礁的白化现象。为了恢复生态，英国和澳大利亚的科学家采用了新方法通过播放某些音乐吸引鱼来病了的珊瑚礁，希望借助它们来恢复生态系统。这一方法已经初见成效。1What causes the phenomenon of coral bleaching？ D ADiverse species.BNoise pollution.AFishing industry.DClimbing temperatures.解析：细节理解题。由第一段最后一句话可知，是全球变暖引起的海水温度的持续上升引起了珊瑚礁的白化现象。2What approach is introduced to recover the coral reefs？ D ARemoving damaged coral reefs.BUsing loudspeakers to keep fish away.ABuilding new homes for sea species.DPlaying certain sounds to appeal to fish.解析：推理判断题。由第二段第一句话可知，通过播放某些音乐来吸引鱼来病了的珊瑚礁，希望借助它们来恢复病了的珊瑚礁的生态系统。3Why are Steve Simpsons words quoted？ C ATo provide some findings of the study.BTo show the progress of the experiment.CTo explain reasons for the new approach.DTo give another solution to the problem.解析：推理判断题。由本段内容可推知，本段解释了这一新办法的理由。4What can we infer from the last paragraph？ C AThe attempts are in vain.BNatural recovery is impossible.CInitial success has been achieved.DThe coral reefs have returned to normal.解析：推理判断题。由最后一段可知，该方法已经初见成效。B(2021济南市模考)Theyre orange, theyre robots and theyre capable of sailing the high seas without human intervention.On Tuesday the National Oceanic and Atmospheric Administration (NOAA) launched a pair of Saildrones (海洋无人机) in Pacific Northwest waters for the first time. Their summer long sailing journey will stretch from Vancouver Island to California. The Saildrone operators will collect data to help set future fishing seasons. The government wants to see whether seagoing robots can extend fishery surveys now performed by expensive manned ships.Nora Cohen from NOAA said，“The 23-foot long seagoing robots can follow a remotely programmed course for up to a year at a time. And they dont require any fuel. We use wind and solar power to drive the sensors. ”He added，“It means that were able to go to places where we dont really want to send people, and go into weather that we really dont want anyone ever to be in, and be able to send measurements back.”The primary mission is to investigate the species and the number of fish in existence and the places where they are. Larry Hufnagle, scientist of NOAA Fisheries in Seattle, said a traditional big NOAA research ship-based survey costs around $25,000 per day. By comparison, one Saildrone costs $2,500 per day.“It could be a significant saving，” Hufnagle said. “But like, anything else, there is a trade-off in what you get and what you dont get. On the manned ship, we have limited time. It takes a lot of people. We spend a fair amount of money. But there is one thing the Saildrone cant do that humans can: cast a net to catch and positively identify the fish detected below. The Saildrones are going to give us additional data, not replacement data.” Nora Cohen said Saildrone, a venture capital-backed company based in Alameda, California, expects to launch a total of 11 of its seagoing robots to survey different waterbodies for NOAA this year. The Bering and Arctic seas, Coastal California and the Gulf of Mexico will be the locations of additional missions.文章大意：本文介绍了海洋无人机的相关情况。5What is the purpose of collecting fish data？ B ATo explore the ocean.BTo assist fishing industry.CTo learn the habits of fish.DTo improve fishing skills.解析：考查细节理解。根据第二段的第三句“The Saildrone operators will collect data to help set future fishing seasons”可知，海洋无人机操作员收集数据的目的是协助渔业。故选B。6What is mainly discussed about the Saildrone in Paragraph 3？ A AIts advantages.BIts appearance.CIts power systems.DIts primary mission.解析：考查细节理解。根据第三段的内容可知，本段主要介绍了海洋无人机遵循远程编程航线的时间长，不需要任何燃料，能进入不想让人进入的地方，能处于不想让人处于的天气中，且能发回测量的结果，以上这些都是它的优势，故选A。7What does the underlined word “trade-off” in Paragraph 5 probably mean？ D ADebate.BReason.CReality.DBalance.解析：考查词义猜测。根据画线词前后的内容可知，海洋无人机可以省一大笔开销，但是也有我们人类可以做到而海洋无人机无法做到的事情，即它有利有弊，我们要权衡得失，故D项的意义与画线词意义最接近。8What can be inferred from the text？ A AThe Saildrone has a promising future.BHufnagle thinks little of the Saildrone.CManned ships will be completely replaced.DProduction of seagoing robots is restricted.解析：考查推理判断。综合全文可知，海洋无人机具有使用成本低、遵循远程编程航线的时间长、不需要任何燃料、能进入不想让人进入的地方且能发回测量的结果等优点，能够帮助确定未来的捕鱼季节及进行渔业调查；且在最后一段谈到Saildrone公司今年将预计总共推出11款远洋航行机器人，为NOAA调查不同的水体。由此可推知，海洋无人机有好的前景。故选A。.短文改错(2021广东省深圳市高级中学高三年级模考)As we all know, over seventy percent of our planet are covered by sea, where is rich in salt as well as fish. Whats more, there is a great deal of oil or gas under the sea. In other words, the sea is the place with so many important things we live in. However, with the world population increased rapidly, overfishing has become a serious problem. Every day a lot of rubbishes and waste water are poured into the sea, so the sea is bad polluted. As a result, the number of fish has obviously decreased. Besides, some are dying out or have been died out. Therefore, it is time for everybody protect the sea.答案：As we all know, over seventy percent of our planet covered by sea, is rich in salt as well as fish. Whats more, there is a great deal of oil gas under the sea. In other words, the sea is place with so many important things we lives . However, with the world population rapidly, overfishing has become a serious problem. Every day a lot of and waste water are poured into the sea, so the sea is polluted. As a result, the number of fish has obviously decreased. Besides, some are dying out or have been died out. Therefore, it is time for everybody protect the sea.解析：1考查主谓一致。句意：众所周知，我们地球百分之七十被海水覆盖。本句主语是不可数名词over seventy percent of our planet，谓语动词应该使用单数形式。所以要把are改为is。2考查定语从句。句意：众所周知，我们地球百分之七十被海水覆盖，它富含盐和鱼。本句的先行词是sea，关系代词which指代先行词，引导定语从句并在句中做主语。而where在句中作状语。所以要把where改为which。3考查连词。句意：而且，在大海下面有很多的石油和天然气。连词and表示并列关系，通常用在肯定句里。而or表示并列通常用于疑问句否定句里。所以要把or改为and。4考查冠词。句意：大海是一个有很多我们赖以生存的东西的地方。根据句意可知应该表示泛指，应该使用不定冠词a表示泛指，而定冠词the表示特指。所以要把the改为a。5考查介词。句意：大海是一个有很多我们赖以生存的东西的地方。动词短语live on“以为生”。所以要把in改为on。6考查非谓语动词。句意：随着世界人口的迅速增加，过度捕鱼成为一个严重的问题。介词with的宾语the world population与动词increase构成主动关系，要用现在分词increasing充当补足语。所以要把increased改为increasing。7考查名词的数。句意：每天都有很多垃圾和污水被倾倒进大海。名词rubbish意为“垃圾”，是不可数名词，没有复数形式。所以要把rubbishes改为rubbish。8考查副词。句意：每天都有很多垃圾和污水被倾倒进大海，大海被污染得很严重。副词通常作状语修饰形容词、副词、动词或整个句子，形容词通常作定语修饰名词代词。句中应该使用副词做状语修饰谓语is polluted。所以要把bad改为badly。9考查动词的语态。句意：而且，一些鱼将要“灭绝”或已经灭绝了。动词短语die out“灭绝”，没有被动语态。所以要删除been。10考查非谓语动词。句意：因此，现在是每个人保护大海的时候了。句中使用了不定式复合结构for sb to do sth.，所以要在everybody后加to。
