(时间：100分钟　满分：120分) 第一部分　阅读(共两节，满分50分) 第一节(共15小题；每小题2.5分，满分37.5分) 阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项。 A The world's oceans are some of the most interesting and breathtaking places on the entire planet.A lot of these oceans have witnessed a variety of disappearances and other mysteries, most of which cannot and have not been explained by modern science.Here are some interesting unsolved sea mysteries of the world. USS Scorpion In February 1969, the USS Scorpion, an American submarine, departed from Norfolk, Virginia, on its way towards the Mediterranean.The crew had almost a decade of experience, and yet the sub disappeared and broke into pieces on the sea floor.There were 99 men aboard the sub, all of whom lost their lives. Baltic Sea Sub In the later half of 2014, a mysterious vessel was spotted by Swedish citizens, many of whom described it as a Russian submarine, in the Baltic Sea.The military spent much time in investigating, but found no sign of the mysterious sub.The search was named “the hunt for Reds in October”． Bermeja Island During the 1970s, Bermeja Island served as a bit of a marker for Mexico and their economic zone.Around 20 years later, the island disappeared without any sign.Along with the island, numerous important documents about major oil reserves also went missing. Gulf of Mexico Shipwreck In 2001, ExxonMobil was laying pipeline in the Gulf of Mexico when they ran into a shipwreck around 2，600 feet under the surface.Upon exploring the shipwreck, archaeologists believed it to be a terrible spell, as something would constantly go wrong when they went down to explore. SS Edmund Fitzgerald Lake Superior is so large that it behaves like an inland ocean, including terrific storms.In November 1975, one such storm struck the vessel SS Edmund Fitzgerald, which was headed to Detroit.The Fitzgerald disappeared after communications were lost.A week later, a sonar(声呐) ship found the vessel 500 feet under the water.Not one body was found, though. [语篇解读]　海洋是整个地球上最有趣和最令人惊叹的地方之一。文章主要介绍了世界上一些与海洋有关的有趣的未解之谜。 1．Why does the author think of USS Scorpion as a mystery? A．99 men died aboard the sub. B．It lost its way towards the Mediterranean. C．The sub still sank even with experienced crew. D．There is no information of the unknown sub. 解析　细节理解题。根据第二段中“The crew had almost a decade of experience, and yet the sub disappeared and broke into pieces on the sea floor.”可知船员们几乎有10年的经验，但这艘潜艇还是消失了，在海底摔成了碎片。由此可知，作者认为蝎子号是一个谜是因为即使有经验丰富的船员，潜水艇还是沉没了。故选C。 答案　C 2．What do Baltic Sea Sub and Gulf of Mexico Shipwreck have in common? A．Both are highly put on a bad spell. B．Both the names of the vessels are unknown. C．Both are found on the beaches. D．Both are said to be Russian vessels. 解析　细节理解题。根据第三段第一句可知2014年下半年，一艘神秘的船只在波罗的海被瑞典公民发现，其中许多人将其描述为一艘俄罗斯潜艇。以及第五段，可知2001年，埃克森美孚公司在墨西哥湾铺设输油管道时，在海底约2 600英尺处遭遇了一艘沉船。在探索沉船时，考古学家认为这是一个可怕的咒语，因为当他们下去探索时，总会有东西出错。由此可知，波罗的海潜艇和墨西哥湾沉船共同之处是都不知道两艘船的名字。故选B。 答案　B 3．Which mystery is different from the others? A．SS Edmund Fitzgerald. B．Bermeja Island. C．Gulf of Mexico Shipwreck. D．USS Scorpion. 解析　细节理解题。根据第四段中第二、三句可知大约20年后，这个岛消失得无影无踪。除了这座岛屿，大量关于主要石油储备的重要文件也消失了。结合其他的谜团都是关于船只的，由此可知，Bermeja岛的谜团与其他的不同。故选B。 答案　B B Accompanied by her father, using a combination of aid and free climbing and taking advantage of some special equipment and ropes for protection，10­year­old Selah made it to the top of El Capitan on June 12 after five days of big wall climbing. Climbing the challenging and adventurous Nose Route of El Capitan was a labor of love for Selah in more than one way.Her parents Mike and Joy Schneiter, fell in love on this 3，000­plus­foot huge rock and she always wanted to feel the way that her parents felt when they were up there together.Selah showed great interest in rock climbing at an early age.She wore her first set of rock­climbing equipment shortly after she learned to walk.She first dreamed of climbing El Capitan when she was 6 or 7. El Capitan is a famous mountain­sized rock in Yosemite National Park.Getting to its top is no easy task.El Capitan with its difficult Nose Route, which runs more than 3，000 feet high up the center of the rock's face, is considered one of the world's hardest big wall climbs and has attracted the best climbers over time.But never before had a youngster accomplished it. Selah's achievement caught national attention.Outside magazine called her the youngest documented person to climb the Nose.Ken Yager, president of the Yosemite Climbing Association, said he also couldn't think of anyone younger who has done it. Selah is humble about her El Capitan accomplishment.“I'm not necessarily a special kid or anything like that，” she said.“There were a few times when I would be so worn that it would kind of discourage me from holding on.But overall, it was just great to stick at it.” Selah shared this advice with other young climbers dreaming of big walls，“ It doesn't take necessarily a super special person to do something like that.You just have to put your mind to it.” [语篇解读] 本文是一篇记叙文。讲述了 10 岁的 Selah 在父亲的陪同下，借助一些特殊装备和绳索，在经历了5天的大岩壁攀登后，于6月12日登上了埃尔卡皮坦山顶的故事。 4．What do we learn about Selah climbing El Capitan? A．She began her climbing on June 5. B．She got inspired by her family history. C．She managed without any external help. D．She was the first female to reach the top. 解析　细节理解题。根据第二段中的“Her parents，Mike and Joy Schneiter, fell in love...feel the way that her parents felt when they were up there together”可知，Selah从她的家族史中受到启发。 答案　B 5．What is the purpose of paragraph 3? A．To state El Capitan's history. B．To prove El Capitan's popularity. C．To introduce El Capitan's location. D．To stress the challenge of climbing El Capitan. 解析　推理判断题。根据第三段中的“El Capitan with its difficult Nose Route...But never before had a youngster accomplished it”可知，攀登埃尔卡皮坦山是十分艰难的。 答案　D 6．Which of the following best describes Selah? A．Determined. B．Generous. C．Warm­hearted. D．Fortunate. 解析　推理判断题。根据第五段中的“There were a few times when I would be so worn...it was just great to stick at it”可知，Selah 是有决心的。 答案　A 7．What may be Selah's advice for other young climbers? A．Dream big and aim high. B．Be committed to your ambition. C．Chance favors the prepared mind. D．Nothing is impossible for a genius. 解析　推理判断题。根据文章最后一段中的“It doesn't take necessarily a super special person to do something like that.You just have to put your mind to it”可知，Selah 给其他年轻攀登者的建议是坚定自己追求的目标。 答案　B C “Protecting our underwater heritage is extremely important and increasingly urgent as no site or shipwreck is now out of bounds for treasure hunters.New technologies have made deep­water wrecks easily accessible and these technologies are getting cheaper，” warns Lyndel Prott. According to estimates by commercial salvors (寻宝者), there are some three million undiscovered shipwrecks scattered across the world's oceans.Even the figures for the known wrecks are impressive.The Northern Shipwrecks Database for example contains 65，000 ship loss records for North America alone from 1500 AD to the present.The Dictionary of Disasters at Sea by Charles Hocking (1969) lists 12，542 sailing ships and war vessels lost between 1824 and 1962. Then there are sunken cities such as the trading town and pirate stronghold (海盗堡垒) of Port Royal in Jamaica, which disappeared beneath the waves after an earthquake in 1692.Or the remnants of ancient civilisations, such as the Lighthouse of Alexandria in Egypt, and the Neolithic villages being discovered under the Black Sea, which some believe could help explain Noah's great flood. These treasures of cultural heritage are under serious threat.Technology now allows extraordinary access to the ocean depths for determined and well­financed treasure hunters.And the potential rewards are huge.In 1985, American salvor Mel Fisher discovered the wreck of the Señora de Atocha, a Spanish ship that sank off the Florida Keys in 1622 with her cargo of gold, silver and jewellery worth an estimated US$400 million. An archaeologist can spend ten years or more studying a ship, conserving its objects and publishing its findings.We gain an enormous amount of information and knowledge from this work.With treasure hunters, all of this is lost.This is tragic, for humanity as a whole. [语篇解读]　本文是一篇说明文。海底探宝猖獗，极大地破坏了这些海底沉船或沉没的遗迹，现在世界联合国教科文组织准备立法，禁止对海下遗迹的掠夺。 8．Why is it important and urgent to protect our underwater heritage? A．Underwater heritage is easily accessible to treasure hunters. B．Underwater heritage is out of reach of archaeologists. C．New technology makes protection of underwater heritage easier. D．There is no law to protect underwater heritage. 解析　细节理解题。由第二段内容可知，因为现代科技进步，探宝者很容易就能到达海下沉船，因此对沉船的保护迫在眉睫。 答案　A 9．What is the third paragraph mainly about? A．Shipwrecks discovered by commercial salvors. B．The main cause of shipwrecks. C．The history of sunken ships. D．The figures of shipwrecks around the world. 解析　段落大意题。综合分析第三段内容可知，本段介绍了已探明的和未探明的海底沉船数量。 答案　D 10．What happened to Port Royal in 1692? A．It was washed away by flood. B．It was beneath the waves after an earthquake. C．It was discovered under the Black Sea. D．It was rebuilt by Noah. 解析　细节理解题。从第四段第一句可知，Port Royal被地震后引起的洪水淹没。 答案　B 11．Why is Mel Fisher mentioned in the fifth paragraph? A．He risked his life in treasure hunting. B．He was one of the most successful commercial salvors. C．He made a great discovery of shipwrecks. D．He had no trouble in finding a shipwreck. 解析　推理判断题。分析第五段内容可知，Mel Fisher曾经发现了一所满载珠宝的西班牙沉船，由此可知，他是最成功的探宝者之一。 答案　B D For years, a question that human beings often ask about the universe is: “Are we alone here？” In January, 2019, the discovery of new Fast Radio Bursts (FRB，快速射电暴) from deep space got many to ask it again. According to Mirror, a Canadian­led team of scientists found 13 FRBs with the help of a radio telescope.First discovered in 2007, FRBs are short bursts of radio waves coming from far outside the Milky Way(银河).Scientists have found over 60 FRBs so far.They last only a few milliseconds but release the same energy as the sun gives off in a day. Among the 13 FRBs, a very unusual repeating signal was found, which came six times from the same location about 1.5 billion light years away.Such an event has only been reported once before, back in 2012.　It may help scientists understand where FRBs are from and what causes them.More importantly, the new FRBs were recorded at unusually low radio frequencies.Most of those previously found have had frequencies of around 1，400 megahertz (MHz), but new bursts are found at even 400MHz—the lowest frequency the telescope can discover.According to the BBC, the low frequency means that the sources of the bursts have changed.It also suggests humans can learn more about the environment where the bursts come from. Avid Loeb, a professor from Harvard University, believes the radio waves may be evidence of alien technology.They may be “leakage from a huge, light­powered ship deep in space，” Loeb told The Independent.And even some Chinese Internet users joked we shouldn't respond to them.However, most researchers believe that FRBs are formed due to the death of a star or the merging (合并) of two black holes. “Science isn't a matter of belief, it's a matter of evidence，” claimed Loeb.So only more advanced technology and more collected data will reveal the truth about FRBs.Time will be the judge. [语篇解读]　这是一篇说明文。多年来，人类经常问的一个关于宇宙的问题是：“我们是孤独的吗？”而据《镜报》报道，一个加拿大科学家领导的团队在射电望远镜的帮助下发现了13个FRB。在13个FRB中，有一个非常不寻常的重复信号，它来自大约15亿光年外的同一位置，并且重复了6次。哈佛大学教授Avid Loeb对此提出了自己的看法。 12．What can we learn about the 13 FRBs from the text? A．They release less energy than the sun does. B．They are from somewhere in the Milky Way. C．They cover 1.5 billion light years in a second. D．The 400MHz FRBs may help man know more. 解析　细节理解题。根据第三段中倒数第三句和最后一句可知，400兆赫的FRB可以帮助人类了解更多。故选D。 答案　D 13．What does the underlined word “It” in paragraph 3 refer to? A．The year of 2012. B．The same location. C．The radio telescope. D．The repeating signal. 解析　词义猜测题。根据上文“Among the 13 FRBs, a very unusual repeating signal was found, which came six times from the same location about 1.5 billion light years away.Such an event has only been reported once before, back in 2012.”可知“It”指代上文中的“重复的信号”。故选D。 答案　D 14．Which statement might Loeb agree with? A．More is needed to explore FRBs. B．We shouldn't respond to the FRBs. C．FRBs are from sun­powered ships in space. D．FRBs are formed due to the death of a star. 解析 推理判断题。根据最后一段可知，Loeb认为探索FRBs需要更多的东西。故选A。 答案　A 15．What might be the best title for the text? A．What Causes FRBs? B．Where Are FRBs From? C．Are Aliens Signaling to Us? D．Is Science a Matter of Belief? 解析　标题归纳题。文章主要说明了多年来，人类经常问的一个关于宇宙的问题是：“我们是孤独的吗？”而据《镜报》报道，一个加拿大科学家领导的团队在射电望远镜的帮助下发现了13个FRBs。在13个FRBs中，发现了一个非常不寻常的重复信号，它来自大约15亿光年外的同一位置，并且重复了6次。哈佛大学教授Avid Loeb对此提出了自己的看法。故选C。 答案　C 第二节(共5小题；每小题2.5分，满分12.5分) 阅读下面的短文，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。 When you look up at the bright stars in the night­time sky, do you wonder what's out there? Of course, your science teachers have taught you that there are stars, planets, and entire galaxies out there. 16 Man has walked on the Moon, but the Moon is fairly close to Earth when you're talking about outer space.How do scientists study the far reaches of the universe? Over the course of history, man has developed amazing technology to help us see beyond our own planet into the vastness of our galaxy and even way beyond. 17 18 Using lenses and mirrors to see beyond Earth's borders, telescopes gave scientists their first glimpse of what exists beyond Earth's atmosphere. What scientists were able to learn with telescopes paved the way for manned space exploration.From trips to the Moon to dozens of manned space shuttle flights, teams of humans were able to travel in space and conduct research on a variety of scientific subjects. 19 The more we learn about outer space, the more we realize how much more there is to explore.This has led scientists to develop even more powerful tools to help them explore the way beyond the places we can go as humans. For example, the telescope is no longer an Earth­bound instrument.In 1990, the Hubble Space Telescope was launched into outer space. 20 With many different cameras and types of scientific instruments, it has provided scientists with invaluable data. A.Who tells us about it? B．But how do we know this? C．Scientists have always been curious. D．It's a piece of technology that's powered by sunlight. E．It's a tool for scientists to explore the universe without difficulty. F．One of the earliest tools for space exploration was the telescope. G．This technology takes the form of some impressive machines and tools.

It is estimated that it was made of about 2.3 million huge stones, each of which measures an average of about 2.5 ton.Therefore, the question arises as to how ancient people lifted the huge stones without modern machinery.Some experts think it was a large number of slaves that managed to make it; some people even think aliens did that. Anyway, I think with the development of science and technology, the mystery can be solved one day. 第二节(满分25分) 阅读下面的材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。 Deep in the forest, my husband and I had fun climbing over and crawling under the downed trees that blocked the dirt path before us.It was May, yet we walked up a snow­covered hill.When we noticed our jeans were wet up to our knees, it did not dampen our spirits.Not once did we say, “Let's turn around.” This was our vacation, and we were on an adventure.Little did we know this was the beginning of many more surprises. The trail was marked as an easy one­kilometer hike yet we were already walking a long distance.Our light­heartedness stopped when we came out into a clearing and saw a parking lot without our rental car in it.As my eyes scanned the surroundings, nothing looked familiar.My heart raced.I realized we were lost in a national park that did not officially open for another week. Usually, I am the calm one in the relationship, but my husband surprised me with his calmness.This did not comfort me; in fact, it heightened my fear.As we walked, I asked my husband to call for help, but there was no cell­phone signal in this isolated(偏僻的)area. It was awfully quiet except for our footsteps hitting the road, and my heavy breathing.My husband suggested we conserve energy and walk slower.With each step on the road, my feet and thighs hurt while my mind raced with thoughts about people who were lost in the Canadian woods for days. My vision sharpened.I noticed everything around me: the trees, rocks and snow.I thought we could eat the snow on the ground in case we needed water.For the first time in my life, I was ready and willing to get a ride, but we did not meet a single car on the road.Silently, I prayed multiple times.We focused on each other, made joint decisions and connected each other through gratitude.We managed to stay on the main road and walked straight on. 注意：续写词数应为150左右。 My husband suddenly spotted a small building on a hill in the distance. Just then, a friendly woman appeared, saying, “Hello.” One possible version： My husband suddenly spotted a small building on a hill in the distance. In no time we found ourselves heading for it.We were filled with hope and excitement to find such a building in the middle of nowhere.We climbed up the hill at a swinging pace as if all the pains had been gone.As we approached, a sign came into sight, which read: Administration Office.However, it was not open for business.The empty hall made us nervous all at once.We stood there hopelessly, wondering what to do next. Just then, a friendly woman appeared, saying, “Hello.” I could barely hold back my enthusiasm and blurted out, “We're lost！” She comforted us and opened a room for us to take a break.Seeing we were cold and hungry, she treated us with hot chocolate.After studying the map, we figured out that our car was parked over three kilometers away.She offered to give us a ride back to our car and we accepted gladly.I felt relieved to see our rental car again.What a blessing to have such an unforgettable experience! 学科网（北京）股份有限公司 $$
