Meanwhile/In the meanwhile Being exposed to loud music too much Ⅴ.阅读理解 A Underwater explorers have discovered an ancient shipwreck(沉船) in the ruins of a long­lost sunken Egyptian city, Heracleion, off the coast of Alexandria in Egypt. Researchers have proved the ship to be over 2，000 years old among the ruins. 1 2 3 4 5 6 [话题语篇提升] Although Heracleion was once an important economic centre, it was destroyed by the forces of nature, sinking rapidly in the water. The remains of the city’s houses, temples, and markets have lain ten metres deep in the Abu Qir Bay, east of present­day Alexandria. As a result，underwater explorers regularly make exciting discoveries there. Among them, statues and stone tablets with words made it possible to figure out the city’s name: Heracleion. Researchers explained that the ship was 25 metres long. The discovery of the shipwreck was fascinating because ships from that period in history were very seldom. The underwater research showed that the ship was struck by several big stones from the nearby temple, making the ship at the bottom of the sea. Dr Mustafa Waziri, Secretary­General of the Higher Archaeology Council, said the ship was in the canal which flowed along the side of the Temple of Amun. An earthquake struck the city, destroying the temple and making the ship sink. While the shipwreck discovery was exciting, underwater explorers discovered the remains of a Greek cemetery dating back to the 4th century BC during the underwater exploration. Researchers explained that the discovery shows the Greek traders lived in the city. They built their own temples near the Temple of Amun, and the remains of both have been found together and in good condition in the sunken city some 7 miles off the coast of Egypt. It is worth noting that the city of Heracleion had been the largest port in Egypt across the Nile Delta, before the city of Alexandria was founded in 331 BC.Several earthquakes destroyed it. (　　)1．Why did the city Heracleion disappear? A．It was destroyed by the Greek traders. B．It was hit and covered by a big flood. C．It was unimportant and was deserted. D．It was ruined and sank into the sea. D (　　)2．What caused the ship to sink into the sea? A．Its own length. B．A terrible earthquake. C．Carrying too many stones. D．The building of a temple. B (　　)3．What can be inferred from the discovery of a Greek cemetery? A．The Greek cemetery was destroyed. B．Greek traders built the Temple of Amun. C．Heracleion was probably a trade centre. D．Greek has a longer history than Egypt. C (　　)4．In which section of a newspaper can we find the text? A．Environment. B．History C．Sport. D．Education. 【语篇解读】 文章通过讲述Heracleion废墟中发现了一艘古代沉船和可追溯到公元前4世纪的希腊墓地遗迹的事迹来探索一些不为人知的历史真相。 B 1．D　细节理解题。根据第二段第一句“Although Heracleion was once an important economic centre, it was destroyed by the forces of nature, sinking rapidly in the water.(尽管Heracleion曾经是一个重要的经济中心，但是它被大自然的力量摧毁了，在水中迅速下沉。)”可知，Heracleion被摧毁了，并沉入海底。故选D。 2．B　细节理解题。根据第三段最后两句“Dr Mustafa Waziri, Secretary­General of the Higher Archaeology Council, said the ship was in the canal which flowed along the side of the Temple of Amun. An earthquake struck the city, destroying the temple and making the ship sink.(高级考古委员会秘书长Mustafa Waziri博士说，这艘船在阿蒙神庙旁边的运河里。一场地震袭击了这座城市，神庙被毁，船沉没。)”可知，船是因为地震沉没的。故选B。 3．C　推理判断题。根据最后一段中的“Researchers explained that the discovery shows the Greek traders lived in the city.(研究人员解释说，这一发现表明希腊商人住在这座城市。)”可知，这里有商人居住；根据本段中的“It is worth noting that the city of Heracleion had been the largest port in Egypt across the Nile Delta, before the city of Alexandria was founded in 331 BC.(值得注意的是，在公元前 331 年亚历山大城建立之前，Heracleion是埃及最大的港口城市，横跨尼罗河三角洲。)”可知，Heracleion有商人居住，它在亚历山大城建立之前还是埃及最大的港口城市，港口城市一般交通便利，故推知Heracleion可能是一个贸易中心。故选C。 4．B　推理判断题。通读本文可知，文章讲述的是水下探险家在埃及亚历山大海岸外消失已久的埃及城市Heracleion废墟中发现了一艘古代沉船和可追溯到公元前4世纪的希腊墓地遗迹，这些发现背后都是承载着一定历史真相的，因此我们可能会在报纸的“History(历史)”版块中读到这篇文章。故选B。 B Marine biologists have documented perhaps a tenth of the 2 million species of marine animals the oceans might host. Experts point out that scientists have mapped nearly all of the surface of the Mars, but less than a quarter of the seabed. A new project hopes to change this. Launched in London on April 27th, Ocean Census aims to discover 100，000 new species of marine animals in 10 years. The project is happening now for two reasons. One is that, the longer scientists wait, the fewer there will be to document. Climate change is heating the oceans. One of Ocean Census’s priorities will be documenting species thought to be in danger from climate change. The second reason is technological. Marine biologists find about 2，000 new species a year, a rate hardly changed since Darwin’s day. Ocean Census thinks it can go faster. Fancy cameras on remote-­operated vehicles allow scientists to scan deep­sea creatures without removing them from their habitat. Taking such creatures to the surface for examination is as fatal as the pressures of the deep sea are for humans. Ocean Census isn’t the first attempt to conduct a systematic survey of life in the oceans. The Census of Marine Life was a ten­-year effort, begun in 2000, to seek out new species. The Global Ocean Sampling Expedition from 2004 to 2006 aimed to document life in the sea by sampling waters from across the world. What the new effort might turn up is impossible to predict. But history suggests it will be fruitful. Many drugs, for example, are originally made biologically, but one type of marine snail, Conus magus, was recently discovered to produce a painkilling material 1，000 times more effective than medicine. To help make use of its data, Ocean Census plans to make it freely available to scientists and the public. The point of exploration, after all, is that you never know what you might find. (　　)5．What does the new project hope to do? A．To document more ocean animals. B．To map out the ocean conditions. C．To improve the ocean climate. D．To sort out endangered species. A (　　)6．Why is it possible for Ocean Census to speed up its work? A．People are aware of the importance of ocean protection. B．Scientists have waited long to document ocean species. C．Deep­sea creatures can be moved to the surface for study. D．Technology has enabled people to study species undersea. D (　　)7．What will the study of Conus magus lead us to do? A．To sample ocean waters of the whole world. B．To begin a systematic survey of ocean life. C．To produce an effective painkilling material. D．To document and save endangered species. C (　　)8．Which can be a suitable title for the text? A．A Document of What Sea Life Is like B．An Exploration of Life Under the Sea C．A History of How We Explore the Sea D．A Journey into the World of the Unknown B 【语篇解读】 文章介绍了英国启动的为期十年的“海洋普查计划”，并介绍了世界各国开展的了解海洋物种的几个项目，以及了解海洋生物的意义。 5．A　细节理解题。根据第一段中的“Experts point out that scientists have mapped nearly all of the surface of the Mars, but less than a quarter of the seabed.(专家指出， 科学家们几乎能把整个火星表面绘制成图，但是只能绘制海底不到四分之一的区域。)”以及第二段中的“Ocean Census aims to discover 100，000 new species of marine animals in 10 years.(海洋普查旨在寻找十万种新的海洋生物。)”可知，这项新的项目旨在记录更多的海洋动物。故选A。 6．D　细节理解题。第二段中的“The second reason is technological. Marine biologists find about 2，000 new species a year, a rate hardly changed since Darwin’s day. Ocean Census thinks it can go faster. Fancy cameras on remote­operated vehicles allow scientists to scan deep­sea creatures without removing them from their habitat.(第二个原因是技术上的。海洋生物学家每年发现大约2 000个新物种，这一速度自达尔文时代以来几乎没有变化。海洋普查计划认为它可以走得更快。远程操作设备上的高级摄像机使科学家无需将深海生物带离栖息地就能对其进行扫描。)”提到现代科技的飞速发展让科学家能够探测深海物种。由此可知，科技使人们能够研究海底的物种，让海洋普查计划有可能加快其工作。故选D。 7．C　推理判断题。根据第三段最后一句“Many drugs, for example, are originally made biologically, but one type of marine snail, Conus magus, was recently discovered to produce a painkilling material 1，000 times more effective than medicine.(例如，许多药物最初都是用生物方法制成的，但最近发现一种名为僧袍芋螺的海洋生物能产生比药物有效1 000倍的止痛物质。)”可推断，这种海洋动物可以被用于研究开发止痛药。故选C。 8．B　主旨大意题。根据文章内容，尤其第二段中的“Launched in London on April 27th, Ocean Census aims to discover 100，000 new species of marine animals in 10 years.”可知，本文介绍英国启动的一项“海洋普查计划”， 并探讨人类在海底探索海洋生命的意义。因此本文的最佳标题是“An Exploration of Life Under the Sea(海底生物的探索)”。故选B。 Ⅵ.七选五 阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。选项中有两项为多余选项。 Oceans are an appealing target for renewable energy production. Waves produce 32，000 terawatt­hours of natural energy per year—for reference, the entire world uses around 23，000 terawatt­hours every year. 1 2 3 4 5 6 The advantages of wave power are clear. 1．____ Turbines(涡轮机) produce electricity through the power of waves, making them a completely pollution­free, renewable energy source. And the amount of kinetic(运动的) energy in a wave is huge and that energy is used to produce electricity. There is also a lot of potential because many countries have access to an ocean that can help power their electric systems. Also, waves are hardly interrupted and almost always in movement. 2．____ D G But the disadvantages of wave energy are serious too. Building factories or electrical wires directly on the beach might prove challenging. 3．____ Local fishing zones could be affected or the factories could lead to more coastal erosion. The high cost is a problem, too. Wave power is a rising energy technology in the early stages of development, so calculating the costs is difficult. 4．____ Because constant movement can lead to more breaking, wave energy factories will most likely need regular and costly maintenance. E F 5．____ For many ocean­bordering countries, wave energy will be a great addition to the renewable energy mix. The bottom line is that wave power has enormous global potential. However, the industry needs more funding and research to finalise the technology involved so that countries can begin adding wave energy to their renewable energy source. C A．Wave energy still needs to be explored. B．They are not affordable to many countries. C．Despite the challenges, there is a future of wave energy. D．Wave energy does not give off greenhouse gases when produced. E．They can cause damage to sea life and the surrounding ecosystems. F．Maintenance for the factories in moving saltwater is very expensive. G．This makes electricity from wave energy a more reliable energy source. 【语篇解读】 文章主要说明了波动能的优势、缺点以及发展前景。 1．D　根据空前一句“The advantages of wave power are clear.(波动能的优势显而易见。)”可知，本段主要介绍了波动能的优势，D项承接上文，具体说明波动能的环保优势：不会释放温室气体，因此D项符合语境。故选D。 2．G　空前两句“There is also a lot of potential because many countries have access to an ocean that can help power their electric systems. Also, waves are hardly interrupted and almost always in movement.”提到还有很大的潜力，因为许多国家都有海洋，可以为它们的电力系统提供动力。而且，波浪几乎没有中断，几乎总是在运动。G项“这使得波浪能发电成为更可靠的能源。”承接上文，符合语境。故选G。 3．E　根据本段第一句“But the disadvantages of wave energy are serious too.”可知，本段主要介绍了海浪发电的弊端。根据空前一句“Building factories or electrical wires directly on the beach might prove challenging.”可知，直接在海滩上建造工厂或架设电线可能会具有挑战性。E项“它们会对海洋生物和周围的生态系统造成损害。”承接上文，说明在海滩上建造工厂或架设电线是如何具有挑战性的，符合语境。故选E。 4．F　根据空前的“The high cost is a problem, too. Wave power is a rising energy technology in the early stages of development, so calculating the costs is difficult.(高昂的成本也是一个问题。波动能是一项处于发展早期阶段的新兴能源技术，因此计算成本是困难的。)”以及下文“Because constant movement can lead to more breaking, wave energy factories will most likely need regular and costly maintenance.(由于不断的移动会导致更多的损坏，波浪能工厂很可能需要定期和昂贵的维护。)”可知，本句主要在说明工厂的维护成本高的问题。因此F项“流动海水工厂的维护费用非常昂贵。”符合语境，其中Maintenance和expensive为关键信息。故选F。 5．C　空处位于句首，应为本段主题句；根据本段中的“For many ocean­bordering countries, wave energy will be a great addition to the renewable energy mix. The bottom line is that wave power has enormous global potential. However, the industry needs more funding and research to finalise the technology involved so that countries can begin adding wave energy to their renewable energy source.”可知，对于许多海洋沿岸国家来说，波浪能将是可再生能源结构的重要补充。总之，波浪能在全球范围内具有巨大的潜力。然而，该行业需要更多的资金和研究来确定所涉及的技术，以便各国开始将波浪能添加到可再生能源中，因此C项“尽管存在挑战，波浪能还是有未来的。”符合语境，承接上文提到的挑战，也引出下文提到的波浪能还是存在未来发展的可能性。故选C。 感谢聆听，再见！ $$
