[本卷满分120分，考试用时100分钟] 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 Animal Conservation Many animal and plant species have become extinct and many more are in danger. Finding ways to protect the earth's wildlife and conserve the natural world they inhabit is now more important than ever. The dodo The dodo is a classic example of how human caused damage to the earth's biology. The flightless dodo was native to the Island of Mauritius in the Indian Ocean. The easily controlled bird became a source of food for sailors and was attacked by animals introduced to the island by humans such as pigs，monkeys and rats. The population of dodos rapidly decreased and the last one was killed in 1681. Rhinos The rhino horn is a highly­prized item for Asian medicine. This has led to the animal being hunted in its natural habitat. Once widespread in Africa and Eurasia，most rhinos now live in protected natural parks and reserves. Their numbers have rapidly decreased in the last 50 years，and the animals remain under constant threat from poachers. The giant pandas The future of the WWF's symbol is far from certain. As few as 1,000 remain in the wild，the Chinese government has set up 33 panda reserves to protect these beautiful animals. However，the panda's distinct black and white patched coat fetches a high price on the black market and determined poachers still pose one of the most serious threats to the animals. Whales Despite the fact that one­third of the world's oceans have been declared whale sanctuaries,7 out of 13 whale species remain endangered. Hunted for their rich supply of oil，their numbers have decreased to just 300. Collisions with ships，poisonous pollution and being caught in fishing nets are other major causes of whale deaths. Tigers The last 100 years has seen a 95% reduction in the number of remaining tigers to between 5,000 and 7,000 and the Bali，Javan，and Caspian tigers are already extinct. The South China tiger is close to disappearing，with only 20 to 30 still alive. Like the rhino horn，the tigers' bones and organs are sought after for traditional Chinese medicines. These items are traded illegally along with tiger skins. [语篇解读]　本文是一篇应用文。文章主要介绍了五种已灭绝或处于濒危的动物。 1．Which group of the following animals has no longer existed according to the text? A．The dodo，rhino and panda. B．The rhino，whale and South China tiger. C．The dodo and the Bali，Javan，and Caspian tigers. D．The rhino，panda，whale and tiger. 解析　C　细节理解题。根据第二段中的“The population of dodos rapidly decreased and the last one was killed in 1681.”以及最后一段中的“...the Bali，Javan，and Caspian tigers are already extinct.”可知，渡渡鸟、巴厘岛虎、爪哇虎和里海虎已经不存在了。故选C。 2．What can serve as a cure for certain diseases? A．The whale's rich oil. B．The rhino horn and tigers' bones and organs. C．The panda's black and white patched coat. D．The dodo's delicious meat. 解析　B　细节理解题。根据最后一段中的“Like the rhino horn，the tigers' bones and organs are sought after for traditional Chinese medicines.”可知，犀牛角和老虎的骨头和器官可以治疗某些疾病。故选B。 3．Which of the following is mentioned in all the descriptions of those wild animals? A．The reason for their extinction or being in danger. B．The way of their life. C．Why they are hunted. D．Punishment for hunting wild animals. 解析　A　细节理解题。根据第二段中的“The easily controlled bird became a source of food for sailors and was attacked by animals...”；第三段中的“The rhino horn...This has led to the animal being hunted in its natural habitat.”；第四段中的“However，the panda's distinct black and white patched coat fetches a high price...pose one of the most serious threats to the animals.”；倒数第二段中的“Hunted for their rich supply of oil...”以及最后一段中的“Like the rhino horn...These items are traded illegally along with tiger skins.”可知，A选项“它们灭绝或濒危的原因”在所有对这些野生动物的描述中都提到了。故选A。 B Zhu Dejun's first job after graduating from college was as a road design engineer at an institute in his hometown，Alashan League，North China's Inner Mongolia autonomous region. In 2011，when Zhu was conducting a road survey along with his colleagues，he saw a plant that he didn't recognize. Later，Zhu learned that the plant was a saxaul tree which is an excellent tree species for sand fixation and afforestation(造林) in desert areas. It's commonly seen，though easily ignored. Known as a desert guardian，a fully grown saxaul tree can hold together a 10­square­meter patch of desert land，according to Zhu. Zhu quit his job at the design institute in 2014 and joined a nonprofit organization，the Society of Entrepreneurs and Ecology Conservation，or SEE，in the same year，concentrating on tackling desertification. The organization，devoted to ecological protection and social responsibility，was located in the Alashan League of Inner Mongolia. During the past eight years，Zhu has been leading a team from SEE to plant saxaul trees in sandy areas in Alashan League and other places of Inner Mongolia. In 2014，the SEE launched a project titled “one hundred million saxaul trees”，aiming to reach that number from 2014 to 2023，turning the desert of more than 133,330 hectares back into a satisfying ecosystem. By the end of 2018，half of the organization's goal had been achieved. In 2016，Ant Finance cooperated with SEE to introduce the Ant Forest platform，not only encouraging people to choose “a low­carbon way” of shopping，traveling and living，but also to help control desertification. Through the participation of a greater number of online users，who grow virtual trees，the SEE Foundation，set up in 2008，has been providing subsidies(补助金) for local herdsmen and farmers while also offering technological support to plant saxaul trees in desert areas. Now，Zhu is the head of the foundation's project to fight desertification. He also gives lectures about saxaul trees and the fight against desertification at schools，hoping to raise awareness among young people.

It is the largest wilderness in the entire country and makes up 25% of the wetlands in the state. The Everglades is home to several rare and endangered species. It is also the third largest national park in the US，after Death Valley National Park and Yellowstone National Park. Each year，about 1 million tourists visit the park. On a global level，it has been announced as a World Heritage Site. Unlike most other national parks，Everglades National Park was created to protect an ecosystem(生态系统) from being damaged. In 1947，President Harry Truman spoke at the official opening of Everglades National Park，saying the goal of creating the park was to protect forever a wild area that could never be replaced. 10,000 different islands make up Everglades National Park. There exists natural wildlife on each of these islands. The Everglades is home to about 30 species that are endangered. In addition，more than 350 bird species and 300 species of fresh and saltwater fish live within the park. The Everglades is also home to 40 species of mammals(哺乳动物). There are many ways to explore the Everglades. Visitors can see alligators(短吻鳄) while hiking the Anhinga Trail. The Everglades is one of the few places on Earth where freshwater alligators and saltwater crocodiles live in the same area. Visitors using airboats are likely to see large groups of birds. Some visitors might enjoy riding bicycles through Shark Valley. Others may want to move slowly through the water where they can see insects and wildlife closely. According to experts，changes to the Everglades are becoming a danger to several different kinds of wildlife. They say it is a result of actions the US government began more than 50 years ago，and settlers began even earlier.

In a new review of previously published studies，researchers from Germany and Denmark took a look at the ways in which noises，such as an airplane passing by or jackhammer digging in the ground，can affect our hearts.Perhaps the most obvious impact of a loud sound while you are sleeping is that it can wake you up.But，even if you don't remember hearing the noise or you don't physically get out of bed，it can disrupt you in ways you may not realize. “Noise is not just causing annoyance，but it actually makes us sick，”said Dr Thomas Münzel，a professor at Johannes Gutenberg University Mainz.“Regardless of where the sound is coming from，if it gets louder than 60 decibels(分贝)，it can increase the risk of heart disease.” When our body hears these noises，it reacts with a stress reaction.In this case，these sudden and unexpected noises cause hormones (荷尔蒙) to speed up and eventually damage the heart.Although the chance that a single noise will affect you is unlikely，it's the constant exposure to the sound that can eventually affect you. “But our heart health isn't the only cause for concern.Long­term noise may also raise the risk of type 2 diabetes，depression，and anxiety disorders，”he warns.In the future，Münzel plans to examine how noises from cars，planes，and other vehicles affect the brain.But despite the amount or the depth of research he conducts，it'll take the help of politicians to improve the impact of noise on our health. “Politicians have to take into account，in particular，the new findings，”Münzel said.“With respect to aircraft noise and airports，it is important to make new laws and set new lower noise limits that protect people living close by the airport instead of the owners of the airport.” [语篇解读]　本文是一篇说明文。文章讲述了德国和丹麦的研究人员研究噪声对人们健康产生的影响，呼吁政治家们关注噪声污染并采取措施解决噪声污染。 12．What do researchers from Germany and Denmark find? A．Noise does little harm to people who are asleep. B．Noise can cause people's memory to get worse sharply. C．Noise has been a widespread concern for a long time. D．Noise louder than 60 decibels may cause heart disease. 解析　D　细节理解题。根据第三段最后一句中的“if it gets louder than 60 decibels (分贝)，it can increase the risk of heart disease”可知，答案为D。 13．Which word can replace the underlined word“disrupt” in Paragraph 2? A．Defeat.　　　　　　 B．Harm. C．Affect. D．Discourage. 解析　B　词义猜测题。根据第二段中最后一句可知，即使你忘记曾听到这样的噪声或者你并没有起床，噪声仍然以你察觉不到的方式对你造成伤害。故选B。 14．What can we infer from the last two paragraphs? A．Politicians should take action to handle noise pollution. B．Münzel will continue other studies on brain diseases. C．Benefits of airport owners are more important than health. D．Attention should be paid to heart health and other diseases. 解析　A　推理判断题。根据最后一段内容可知，政治家们必须考虑到这些调查结果。至于飞机噪声和机场，重要的是制定新的法规和更低噪声的限度来保护机场附近的居民而不是保护机场所有者的利益。故选A。 15．Which can be the best title for the text? A．Who Is to Blame for Noise Pollution B．What Should Be Done to Stop Noise C．How Münzel Carried Out His Research D．How Noise Pollution Harms Our Body 解析　D　标题判断题。本文着重讲述了德国和丹麦的研究人员对于噪声如何影响人们的心脏进行了研究。听见噪声的时候，我们的身体会产生应激反应。在这种情况下，出乎意料的噪声会导致荷尔蒙分泌加快，最终损害心脏。故选D。A、B、C项都是属于文中的细节内容，不能概括全文的中心思想。 第二节(共5小题；每小题2.5分，满分12.5分) 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。 Venice is suffering the worst flooding the city has experienced in 50 years. The city is “on its knees” and Venetian Mayor Luigi Brugnaro tweeted as water submerged(淹没) much of the famous historical city. While floods are a normal part of life in Venice，they have never happened with such frequency before. Experts say that climate change is likely to blame. 16 The Venetian council voted against a measure to fight climate change just a few moments before their chamber(会议厅) flooded. Flooding is just one of the many impacts from climate change that is being experienced with more frequency and globally threatening many vulnerable (脆弱的) areas and regions. There is a threat that is not often considered. 17 Natural and man­made heritage sites throughout the world are in danger of being damaged or destroyed by climate change. 18 Some will be hit by flooding，like Venice，others by extreme weather events or rising temperatures. For instance，George Town，the capital of the Malaysian state Penang faces rising sea levels，landslides and more severe typhoons，while Yellowstone ecosystem in the western United States faces melting snows，more frequent wildfires and a changing ecosystem. Changes in the ocean will have a profound impact on many of these sites. 19 And rising sea levels threaten to wash away many of the world's great archaeological sites. Experts say that the solutions to saving these sites will be varied, but many will be very expensive. 20 A．Different ways can be used to save these sites. B．Climate change will impact these sites in different ways. C．It is the damage from climate change to the world's heritage. D．But putting in place protective measures has proven difficult. E．Warming water threatens to kill much of the coral in the Great Barrier Reef. F．Many heritage sites on land are facing the great threat posed by global warming. G．Therefore，they suggest that countries should work together to protect heritage sites. [语篇解读]　本文是一篇说明文。气候剧变威胁着全球各地的自然与文化遗址，拯救刻不容缓。 16．解析　D　根据后文“The Venetian council voted against a measure to fight climate change...”可知，此处在讨论采取应对措施，D项中的“measure”呼应后文的“a measure”。故选D。 17．解析　C　根据前文“There is a threat that is not often considered.”可知，有一种不常被考虑到的威胁，再结合后文“Natural and man­made heritage sites...by climate change.”可知，这种威胁就是气候变化对世界遗产的破坏，所以选项C切合文意。故选C。 18．解析　B　根据后文“Some will be hit by flooding，like Venice，others by extreme weather events or rising temperatures.”及之后的例子可知，此处是讲气候变化影响世界遗产的不同方式，选项B切合文意。故选B。 19．解析　E　前文提到海洋变化会对世界遗产产生影响，根据后文“And rising sea levels threaten to wash away many of the world's great archaeological sites.”可知，此处是举例说明，选项E与后文句式相同，内容统一(海水变暖会杀死大堡礁的大量珊瑚)。故选E。 20．解析　G　根据前文“Experts say that the solutions to saving these sites will be varied，but many will be very expensive.”可知，此处是指专家们认为拯救这些遗产地的方法多种多样，但大都费用昂贵，所以各个国家应该团结起来保护世界遗产，选项G切合文意。故选G。 第二部分　语言运用(共两节，满分30分) 第一节(共15小题；每小题1分，满分15分) 阅读下面短文，从短文后各题所给的A、B、C、D四个选项中选出可以填入空白处的最佳选项。 After lunch, without permission from parents, the two boys set off to explore the part of the beach which lay beyond the headland.They had persuaded their young sister not to 21 them, saying that the long walk would be too 22 for her.Once they had got in the headland, the beach reached away endlessly before them.It was like 23 a new world.There were damp, dark caves to 24 ; there were many 25 among the rocks, full of sea creatures (生物); and，here and there along the beach were those 26 objects, washed up and 27 by the tide.

Learning about the alarming situation those animals are facing，I am deeply worried that they will soon die out if measures aren't taken to protect them.It is surprising that these animals' death mainly results from humans' activities.So what we should do is stop polluting and destroying their habitats. To do this, I hope WWF can try to raise people's awareness of protecting animals and call on people to live in harmony with nature.Only by taking necessary measures can we save and protect them. Yours， Li Hua 第二节(满分25分) 阅读下面材料，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。续写词数应为150左右。 I was invited to a cookout on an old friend's farm in western Washington.I parked my car outside the farm and walked past a milking house which had apparently not been used in many years.A noise at a window caught my attention, so I entered it.It was a hummingbird(蜂鸟), desperately trying to escape.She was covered in spider­webs(蛛网)and was barely able to move her wings.She ceased her struggle the instant I picked her up. With the bird in my cupped hand, I looked around to see how she had gotten in.The broken window glass was the likely answer.I stuffed a piece of cloth into the hole and took her outside, closing the door securely behind me. When I opened my hand, the bird did not fly away; she sat looking at me with her bright eyes.I removed the sticky spider­webs that covered her head and wings.Still, she made no attempt to fly.Perhaps she had been struggling against the window too long and was too tired? Or too thirsty? As I carried her up the blackberry­lined path toward my car where I kept a water bottle, she began to move.I stopped, and she soon took wing but did not immediately fly away.Hovering(悬停), she approached within six inches of my face.For a very long moment, this tiny creature looked into my eyes, turning her head from side to side.Then she flew quickly out of sight. During the cookout, I told my hosts about the hummingbird incident.They promised to fix the window.As I was departing, my friends walked me to my car.I was standing by the car when a hummingbird flew to the center of our group and began hovering.She turned from person to person until she came to me.She again looked directly into my eyes, then let out a squeaking call and was gone.For a moment, all were speechless.Then someone said, “She must have come to say good­bye.” A few weeks later, I went to the farm again. I was just about to leave when the hummingbird appeared. 【文章大意】　作者被邀请去一个农场享用露天烧烤，发现有只蜂鸟被蛛网困住了，于是作者把这只蜂鸟救了。但是，这只蜂鸟却迟迟不肯飞走，徘徊了许久后才离开。后来，在作者准备离开时，这只蜂鸟又飞回到作者面前，好像是在和作者告别。 【写作指导】 根据续写第一段的首句“几周后，我又回到了这个农场。”可知，续写第一段应该描述“我”回到农场后的场景。根据上文可知，东道主答应我们会把窗户修补好，所以“我”这次来的目的很可能是看他们是否履行了自己的诺言；目的也可以是“我”又来拜访老朋友，顺便看一下窗户是否修补好了。通常情况，这个窗户应该是被修补好了。此外，续写第一段也可以穿插一些“我”与朋友之间的互动。续写第一段可以设置一个小矛盾，即一开始“我”没有见到蜂鸟的失落，然后续写第二段“我”正准备离开时蜂鸟出现。另外该段也可以描述我们吃露天烧烤时的场面。 根据续写第二段的首句“我正要离开，这时这只蜂鸟突然出现。”可知，续写第二段应该主要写“我”与蜂鸟之间的互动。可以通过对蜂鸟进行细节描写(外貌、动作等)，再结合“我”的情绪与动作展开构思。结尾可以围绕好几个点展开：可以写蜂鸟再次与“我”告别，也可以讲述“我”与蜂鸟相知相惜。还可以从“我”与蜂鸟这段珍贵的相遇与回忆入手，也可以从人与自然的角度切入。 【参考范文】 A few weeks later, I went to the farm again. I still remembered my friends' promise so I went past the abandoned milking house to see if they had fixed the broken window. To my satisfaction, no other tiny creatures would meet this trouble any more. As I approached the farm , I was greeted by a spicy smell of the barbecue, urging me to walk faster. We were totally immersed in the peaceful atmosphere, enjoying the delicate cuisines, talking about our interesting experiences and singing songs till the sun set.The evening glow spreading across the farm, it was time for us to say goodbye so we went to the parking lot together. I was just about to leave when the hummingbird appeared.With a squeaking call, she dived towards me and hovered before my face，looking at me with her bright eyes.Then she stopped on my left shoulder. I patted her on the back which was covered by colorful feathers. And I took out my water bottle, trying to give her some water.Content and joyful, she flew about 2 meters above the ground, turning her head from side to side as if expressing her gratitude for saving her life to me again. At that moment, happiness and the feeling of being moved mingled，welling up into my heart, tears rolling down my cheeks. 学科网（北京）股份有限公司 $$
