Ⅰ.阅读理解 语篇解读　本文是一篇说明文，介绍了猛犸洞穴国家公园的石灰岩洞穴系统的形成过程和历史、文化意义，以及政府为开发和保护这个自然奇观做出的努力。 37 Mammoth Cave National Park preserves this unique and historical natural wonder.As large as the limestone cave system is，park officials，estimate there may be another 600 miles of cave passageways that have yet to be explored.The incredible rock formations have resulted in the park being recognized as a World Heritage Site，thanks to its extraordinary size and scientific importance—making it one of only 13 natural US sites with that title. 38 The caves were created naturally by the process of limestone wearing away.Rain and rivers slowly break down and shape soft limestone，which creates the vast underground network.Not only are they an amazing destination to visit，but the system also provides drinking water for roughly 40% of the US population，and they’re of historical significance too. 39 The caves act as a time capsule that preserves over 5,000 years of human history—and the caves’ first explorers were Native Americans，who mined the upper levels of Mammoth Cave.Thanks to the cave system’s atmosphere and natural protection from any kind of human disturbance，the archaeological(考古的) sites have been left in great shape. 40 Mammoth Cave was established as a national park thanks to strong local support.Back in the 1920s，Secretary of the Interior Hubert Work created the Southern Appalachian National Park Commission in 1925 to survey proposed park sites，including the caves.After years of work acquiring the land for the park，as well as building roads，trails(小径)，and public facilities，Mammoth Cave National Park was established on July 1,1941.The park now receives around 2 million visitors a year，with roughly a quarter taking a tour of the caves—everything from a cultural tour to the more adventurous climbing tours on offer.The cave supports more than 130 wildlife species，such as the eyeless cavefish，which has adapted to the lightless environment by no longer growing eyes，and the cave crayfish. 41 1.What has made Mammoth Cave National Park a World Heritage Site? A.The wildlife species. B.The rock formations. C.The cave passageways. D.The scientific discovery. √ 细节理解题。根据第二段第三句“The incredible rock formations have resulted in the park being recognized as a World Heritage Site...”可知，让猛犸洞穴国家公园成为公认的世界遗产的是它的岩层，故选B。 解析 42 2.Why are the caves of historical value? A.They are an amazing destination to visit. B.They were first explored by Native Americans. C.They provide drinking water for the Americans. D.They preserve human history of over 5000 years. √ 推理判断题。根据第三段末句中“and they’re of historical significance too”和第四段第一句“The caves act as a time capsule that preserves over 5,000 years of human history...”可推知，这些洞穴具有历史价值的原因是它保存着人类五千多年的历史，故选D。 解析 43 3.What can be inferred from the last paragraph? A.It took a lot of work to establish the park. B.Local people donated the land for the park. C.Around 2 million people visit the caves annually. D.The site of the park was decided by the secretary. √ 推理判断题。根据最后一段的“Back in the 1920s，Secretary of Interior Hubert Work created...in 1925 to survey proposed park sites，including the caves.After years of work...Mammoth Cave National Park was established on July 1,1941.”可推知，建立这个公园做了大量的工作。故选A。 解析 44 4.What can be the best title of the passage? A.Taking Cultural and Adventurous Tours B.Preserving a Unique and Historical Wonder C.Exploring the World’s Longest Cave System D.Establishing Mammoth Cave National Park √ 标题归纳题。纵观全文，前四段介绍猛犸洞穴国家公园的石灰岩洞穴系统的形成过程和历史、文化意义，最后一段介绍了政府为开发这个国家公园做出的努力以及该公园现在的发展状况，因此可知全文围绕“探索世界上最长的洞穴系统”展开进行了多方面多角度的描述，故选C。 解析 45 B As the threat against coral reefs has increased，researchers are introducing innovative methods to farm healthy corals more efficiently. 语篇解读　本文是一篇说明文。文章主要介绍了修复珊瑚礁的新方法。 46 Unlike the traditional way of growing corals in the ocean，land-based nurseries nurture(培育) corals in tanks before planting them onto reefs.While the operations tend to come with a high price tag and are more labor intensive，they provide an opportunity to raise corals in a controlled environment where experimental methods could be used and allow for repairing reefs on a massive scale. 47 These methods include growing corals in tanks on land，or using advanced techniques to promote growth rates and adaptability to the changing environment.Coral Vita，a for-profit company in Grand Bahama，can now grow corals up to 50 times faster than in nature by cutting corals into small pieces，a process known as “microfragmentation”. 48 The farm is also equipped with a high-tech aquaculture system，referred to by Coral Vita employees as the “life support system”，which can regulate water quality through temperature，pH and other adjustable settings.The system can be set up elsewhere with some adjustments for a region’s specific coral.“It can be very plug and play，which is really important for large-scale restoration，” says Teicher，founder of Coral Vita. 49 The potential for large scale is critical to Coral Vita’s business plan，which is connected to the idea or “selling restoration as a service”.In 2021，Coral Vita signed its first restoration contracts with the Grand Bahama Port Authority.“There are about 100 countries and regions with coral reefs，” Teicher says.“There need to be large-scale coral farms in every single one of them.The amount of funding in the non-profit space is a drop in the bucket，and our model could help make the field less dependent on donations.” 50 Marine biologist David Vaughan points out that Coral Vita may have a couple million dollars in start-up costs and plants fewer than 5,000 to 10,000 corals a year.“That isn’t the economic scale that we need to get this to，” Vaughan says，adding hundreds of thousands of operations “costing couple of dollars a coral” will be required. 51 5.In which aspect are new methods of coral restoration different from traditional ways? A.Growing corals can be more economical. B.Fewer workers are needed to grow corals. C.Corals are grown in artificial environments. D.New methods are more environment-friendly. √ 推理判断题。根据第二段可知，新方法是在陆地上的水箱里种植珊瑚，不像传统方法在自然环境中种植，故选C。 解析 52 6.What does Teicher mean by saying “plug and play”？ A.The farm’s technology is advanced. B.The system is easy to operate. C.Many places have brought in the system. D.He is confident of his farm’s future. √ 词义猜测题。根据第四段中的“The system can be set up elsewhere with some adjustments for a region’s specific coral.”推断，Teicher的话的意思是系统操作方便。plug and play为“即插即用的”之意。故选B。 解析 53 7.Why does Teicher choose the for-profit model? A.Because the model can help him become rich. B.Because the model is required by the authority. C.Because there are fewer non-profit companies. D.Because donations are not enough for restoration. √ 54 推理判断题。根据第五段中的“There need to be large-scale coral farms in every single one of them.The amount of funding in the non-profit space is a drop in the bucket，and our model could help make the field less dependent on donations.”可推知，慈善捐款对于大规模修复珊瑚礁是不够的。因此Teicher选择营利性模式。故选D。 解析 8.What is Vaughan’s attitude towards Coral Vita’s plan? A.Approving. B.Skeptical. C.Unclear. D.Tolerant. √ 观点态度题。最后一段中Vaughan先指出Coral Vita的启动资金可能有数百万，然而一年只种植了少于5 000到10 000株珊瑚。接着他说这不是我们想要达到的规模。因此Vaughan对Coral Vita的计划持有怀疑态度。故选B。 解析 56 Advantages of Solar Power As the name suggests，solar power makes the most of the sunlight and is put to good use for its users. Ⅱ.七选五 语篇解读　本文是一篇说明文。主要讲的是太阳能的优点。 57 Despite some disadvantages，the advantages of it are so great that they cannot be ignored.In short，solar electricity system is an excellent addition to other conventional sources of energy. 1 A.So it is time to take action. B.You cannot ignore the advantages mentioned above. C.When referred to，solar energy is perhaps the best power in the world. D.Also，the flexible system allows you to use it on a wide range of applications. E.But you need to know how and where to make it，where to get the parts affordably etc. F.This power does not cause any pollution，which is why it is such an attraction to many. G.Here are some of the advantages of equipping a solar power system in your home or office. √ 58 根据文章标题以及第二段的“A solar panel system...can sufficiently reduce or even cancel your electric bill”“It’s simple to operate as well and this is another advantage.”和第三段第一句可知，空格处引起下文对太阳能的优点的详细介绍，G选项“以下是在家中或办公室安装太阳能系统的一些优点。”符合语境，故选G。 解析 59 A solar panel system，when coupled to your electric function，can sufficiently reduce or even cancel your electric bill，yet providing you with the option of using traditional power whenever needed. 2 It’s simple to operate as well and this is another advantage.Just ensure that you have the right technology in terms of space use and performance. A.So it is time to take action. B.You cannot ignore the advantages mentioned above. C.When referred to，solar energy is perhaps the best power in the world. D.Also，the flexible system allows you to use it on a wide range of applications. E.But you need to know how and where to make it，where to get the parts affordably etc. F.This power does not cause any pollution，which is why it is such an attraction to many. G.Here are some of the advantages of equipping a solar power system in your home or office. √ 60 根据空格前后句可知，空格处同样介绍的是这种太阳能电池板系统的优点，根据后文中的“Just ensure that you have the right technology in terms of space use and performance.”可知，D选项符合语境，说明只要你掌握了空间利用和性能方面的技术，这种灵活的系统应用范围甚广，故选D。 解析 61 But perhaps the most widely well-known advantage of solar power is that this is green energy. 3 This is a great advantage in today’s world where we need to be concerned about the high levels of pollution and global warming. A.So it is time to take action. B.You cannot ignore the advantages mentioned above. C.When referred to，solar energy is perhaps the best power in the world. D.Also，the flexible system allows you to use it on a wide range of applications. E.But you need to know how and where to make it，where to get the parts affordably etc. F.This power does not cause any pollution，which is why it is such an attraction to many. G.Here are some of the advantages of equipping a solar power system in your home or office. √ 62 空格前一句指出太阳能是一种绿色能源，F选项说明了太阳能环保这一个优点，和空前说它是绿色能源相呼应，故选F。 解析 63 Let us all take some responsibility and do something that can clean up our atmosphere to some extent at least.So while on the one hand solar power is clean，on the other hand，it can also greatly reduce the electricity bill of the users. 64 4 So if you are thinking in terms of installing a solar electric system in your home or commercial property，you should go ahead and do it by all means. A.So it is time to take action. B.You cannot ignore the advantages mentioned above. C.When referred to，solar energy is perhaps the best power in the world. D.Also，the flexible system allows you to use it on a wide range of applications. E.But you need to know how and where to make it，where to get the parts affordably etc. F.This power does not cause any pollution，which is why it is such an attraction to many. G.Here are some of the advantages of equipping a solar power system in your home or office. √ 65 空格后给读者提出了安装太阳能电力系统的建议，因此空格处应该说明要安装这种太阳能电力系统的原因，结合前面讲的太阳能电力系统的优点可知，B选项很好地解释了为什么一定要安装这种系统，故选B。 解析 66 And the best news is that the solar power system can be built in your house itself. 5 That is why you need a brochure that can tell you all about these issues. A.So it is time to take action. B.You cannot ignore the advantages mentioned above. C.When referred to，solar energy is perhaps the best power in the world. D.Also，the flexible system allows you to use it on a wide range of applications. E.But you need to know how and where to make it，where to get the parts affordably etc. F.This power does not cause any pollution，which is why it is such an attraction to many. G.Here are some of the advantages of equipping a solar power system in your home or office. √ 67 根据空格后一句“That is why you need a brochure that can tell you all about these issues.”可知，空格处应提到某些问题。E选项提到了一些问题，和后文需要一个能告诉这些问题的答案的小册子相呼应，故选E。 解析 68 China has detailed measures to boost its climate change monitoring and risk prevention capabilities，marking a significant step forward in the country’s efforts 1. (enhance) its climate resilience(气候适应性). Ⅲ.语法填空 语篇解读　本文是一篇说明文。文章主要介绍了中国已经采取了详细的措施来提高气候变化监测和风险预防能力，这标志着中国在提高气候适应能力方面迈出了重要的一步。 to enhance 考查非谓语动词。非谓语动词担当名词efforts的后置定语，要用不定式。故填to enhance。 解析 69 The country will seek to build a climate-resilient society 2._________ climate change monitoring and early warning capability will reach an advanced level globally and the climate risk management and prevention system will 3. (basic) mature，according to the National Climate Change Adaptation Strategy 2035， where basically 2.考查定语从句。句中先行词为society，关系词在定语从句中担当地点状语，要用关系副词where引导定语从句。故填where。 3.考查副词。修饰动词mature，要用副词形式作状语。故填basically。 解析 70 jointly 4. (publish) by 17 departments including the Ministry of Ecology and Environment. published 考查非谓语动词。逻辑主语the National Climate Change Adaptation Strategy 2035与publish之间存在被动关系，需用过去分词作后置定语。故填published。 解析 71 The first time China 5. (issue) a national climate change adaptation strategy，China took measures to prevent and control major climate-related disaster risks 6.______ an effective manner，and greatly improved the technical and standard system for adapting to climate change. issued 5.考查时态。此处是时间状语从句的谓语动词，根据主句谓语动词took的时态可知，从句用一般过去时。故填issued。 6.考查介词。in a(n)...manner意为“以……方式”，为固定短语。故填in。 解析 in 72 Since then，positive results 7. (achieve) in improving adaptation to climate change in key regions and industries. have been achieved 考查时态、语态和主谓一致。根据时间状语Since then可判断，时态为现在完成时；主语为positive results，复数，和动词achieve之间存在被动关系，所以用被动语态。故填have been achieved。 解析 73 As the global climate 8. (far) warms，the long-term unfavorable effects and extreme weather events brought about by climate change will pose 9. increasingly serious threat to China’s economic development. further an 74 8.考查副词的比较级。修饰动词warms，用副词形式。根据句意可知，此处表示随着全球气候进一步变暖，应用比较级。注意further和farther之间的区别：farther一般只用于表示有形距离，是指距离(空间)或时间上更远；而further既可表示有形距离，又可表示程度上进一步。本空为程度上进一步地。故填further。 9.考查冠词。修饰可数名词单数threat，此处是泛指，用不定冠词。由于increasingly的发音以元音音素开头，应用不定冠词an。故填an。 解析 The document underlined measures to improve climate change monitoring and forecasting services，enhance assessment of climate change impacts and risks，and 10. (strength) disaster prevention. strengthen 考查非谓语动词。空处与前面的to improve...，(to) enhance...并列，作measures的后置定语，空前省略了不定式符号to。故填strengthen。 解析 返 回 76 本课结束 $
