He founded and was head of Microsoft for years.Gates was born into a rich family in the state of Washington. His father was a lawyer; his mother was a banker. He is famous for being taken as the father of the modern computer. He studied at Harvard University but did not graduate because of his desire to develop new software.As a 13yearold student, Gates was introduced to computer programming. In 1975, Gates spoke to a company called Micro Instrumentation and Telemetry Systems (MITS). He convinced the owner of the company that he had written a program that would work well and make big money. The owner bought into Gates inventions, and the two men reached an agreement to develop software for the company. Then the Microsoft Company was born. Gates went on to develop the Windows operating system with then partner IBM. The two companies had differences though, and their partnership ended quickly. Gates worked as CEO until 2000. He remained active with the company for several years before leaving the company in 2008. In 2014, Bill Gates became the technical advisor of the firm.第二部分：阅读理解(共两节，满分35分)第一节(共10小题；每小题2.5分，满分25分)阅读下列短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。AWhen I took Amy home from the animal shelter, she was scared. I believed she had been abused (虐待) because she was afraid of anything my husband, Bill, or I held in our hands. With a lot of care and attention, she became a great dog that surprised us every day.About three years ago, Amy and I joined a volunteer project called Canines with Class. At our first school visit, Officer Lisa called Amy and asked her to show how to shake hands and give a high five. The students clapped (拍手) in joy and Amy received a reward. Then the students got to touch the dog. One by one they came up to meet Amy. Some of them started talking to me about their own pets. I didnt feel worried any more. I thought the children liked staying with us.On our next school visit, I put a big chain (链条) on Amys neck and walked away from her. You could see that Amy was not happy. When I took the chain off her neck, Amy shook her tail happily and wouldnt stop licking (舔) my face. That was when we talked about “breaking the chain”On our third school trip, Amy started acting poorly when it was time to show off a few tricks. The students watched to see how I would correct her mistakes. It was a good chance to explain that if your dog doesnt do exactly what you ask, you dont have to shout at her or hit her to make it right. I think the children have learned a lot about respect and patience.Amy loves the program and has come so far since I found her a few years ago. Amy has broken the chain, and the love she gives to those children will help them become good pet owners.语篇解读：本文是一篇记叙文。作者与自己领养的狗参加了一个志愿者项目，旨在告诉人们要善待动物。21During the first school visit, the author was most probably _.AnervousBencouragedCcalm Dupset解析：选B推理判断题。根据第二段的“Some of them started . staying with us.”可推断，刚开始作者也很担心，但是和孩子们交流之后发现，孩子们也喜欢他们来学校，因此作者深受鼓舞。22What was the purpose of the second school visit?ATo show how dogs get happy.BTo encourage children to be free.CTo encourage children to save dogs.DTo show why we should stop using dog chains.解析：选D细节理解题。根据第三段的“That was when we talked about breaking the chain.”可知，第二次去学校交流的目的是为了告诉孩子们狗不喜欢被链子拴住，我们应该停止使用狗链。23What did the children learn from the third school trip?ADogs are stupid at times.BEveryone makes mistakes.CDog owners should be patient.DPeople should respect each other.解析：选C推理判断题。根据第四段的“It was a good chance . respect and patience.”可推断，孩子们学会了对宠物要有耐心。BIn an effort to stop poaching (偷猎) and protect endangered species, people are using technology previously created to discover stars.Claire Burke, who led the project, says the application of the starhunting tech has so far paid off big for conservation.“Since animals and humans in thermal imagery (热成像) glow in the same way as stars in space, we have been able to combine the technical expertise of astronomers with the conservation knowledge of ecologists to develop a system to find the animals or poachers automatically，” she said in a statement.In addition to species identification, the software can also provide an overview of health.Burke said that diseased or injured animals give off a different thermal imagery than the healthy ones.“The real advantage this gives you is that if you know how many animals you have and where they are and what kind of health they are in, then you can work out a good conservation strategy for looking after them，” she said.The following is a post written by Burke on Twitter: More animals for the thermal imagery library.Thanks to Chester Zoo Science ScienceatCZ for letting us observe their fantastic creatures.Images are giraffes, Indian elephants, and fruit bats. Claire Burke (CBurkeSci) October 27.To train the software on a wide variety of heat signatures from different species, the team of researchers spent time collecting thermal imagery of animals.Their first field trial to detect Riverine rabbits, one of the most endangered mammals in the world (with only 500 living adults left in the wild), was a complete success.“The rabbits are very small, so we flew the drone (无人机) quite low to the ground at a height of 20 meters (65 feet)Although this limited the area we could cover with the drone, we managed to see the rabbit five times，” said Burke.“Given that there have only been about 1,000 times people have seen Riverine rabbits, it was a real success.”语篇解读：本文是一篇说明文。为保护濒危动物、防止偷猎，研究人员利用天文学中用来寻星的技术来定位动物和偷猎者。24What can people decide by observing the thermal imagery of the animals?AWhat the animals are doing.BWhen the animals need help.CWhether the animals are healthy.DWhy the animals are in danger.解析：选C细节理解题。根据第二段第一句“In addition to species identification, the software can also provide an overview of health.”可知，使用这种热成像技术，不仅可以辨别物种，而且还能观测到动物的健康状况。25What did the researchers find out after detecting the Riverine rabbits?AThe number of them is decreasing.BIt is difficult for people to identify them.CThere are more of them than people thought.DIt is easier to find them using the hightech tool.解析：选D推理判断题。根据文章最后两句可知，南非山兔非常稀有，研究者们使用这种新技术观察到南非山兔5次，相比起过去人们共观察到南非山兔大约1 000次，这个比率已经非常高了。26What is the text mainly about?ATechnology has helped a lot in helping the endangered animals.BResearchers use stargazing tools to protect endangered species.CWhat we should do to protect the endangered animals.DScientists are working hard to protect the environment.解析：选B主旨大意题。本文介绍了研究人员利用天文学中用来寻找星星的工具来对濒危动物实施保护。CThe sun rises above the Arctic Ocean (北冰洋). Across the frozen sea, a white bear moves slowly.The bear stops and sways (摇晃) his head from side to side. There is nothing to see but endless ice and red sky. Then his powerful nose senses what his eyes cannot: a beluga whale is nearby.The bear follows the smell and spots a large hole in the ice where a small white whale is swimming. He silently walks toward the hole, then stops, standing still. The whale does not see the bear, whose white fur makes him appear invisible (看不见的) against the ice.Finally, the whale swims close to where the bear is waiting. With terrifying speed, the bear comes to life and moves toward the whale. In a moment it is over, and the bear eats his first meal in nearly a week.Polar bears rule the frozen sea, but their ancestors werent always built for ice and snow. The first Arctic bears were brown bears, a species that includes grizzly bears. They came to the icy north over a hundred thousand years ago.No one knows for sure why these bears traveled to such a cold place. Scientists think they might have wandered north looking for food. Maybe they became trapped by glaciers and couldnt leave. Whatever the reason, the bears never should have survived.But they did. They got used to their new environment. Their bodies changed. Their behavior changed, too. Eventually, the bears developed into an entirely new species: the polar bear. You can see some of the characteristics that polar bears developed to survive.Sadly, these characteristics may now threaten the polar bears survival. As sea ice melts due to global warming, polar bears are frequently forced to come ashore (在岸上). They are poor hunters on land, which means they often go a long time between meals. The polar bear, king of the Arctic, is now classified as a threatened species.Although the future of the polar bear is unknown, the tale of two bears continues. As temperatures rise, grizzly bears have been spotted moving north into polar bear territory (领地). These longlost cousins, once forced apart by nature, are coming back together again.语篇解读：本文是一篇说明文。北极熊的祖先为适应环境而不断改变自身特征，而现在这些特征却让北极熊陷入困境。27What can be inferred about the white bear mentioned in the first four paragraphs?AIt is noisy.BIt is smelly.CIt is starving. DIt has good eyesight.解析：选C细节理解题。由第四段最后一句“In a moment it is over, and the bear eats his first meal in nearly a week.”可知，这头白熊很饿。28What do we know about polar bears ancestors?AThey were a darkercolored species.BThey were born to live in ice and snow.CThey had no trouble getting used to the icy north.DThey came to the Arctic Ocean about 1,000 years ago.解析：选A细节理解题。由第五段前两句“Polar bears rule the frozen sea, but their ancestors werent always built for ice and snow. The first Arctic bears were brown bears, a species that includes grizzly bears.”可知，北极熊的祖先毛皮颜色更深一些。29Why are polar bears struggling to survive?AThey are losing their hunting ground.BThey are threatened by other animals.CThey are spending little time on land.DThey have difficulty reaching the shore.解析：选A推理判断题。由倒数第二段中的“As sea ice melts due to global warming, polar bears are frequently forced to come ashore (在岸上)”可知，随着气温上升，北极熊狩猎的海水冰面消失，使得它们的生存面临威胁。30Which of the following can be the best title for the text?AThe climate changeBThe polar bears favorite mealCThe dark past of the polar bearDThe mysteries of the Arctic Ocean解析：选C标题归纳题。文章讲到北极熊的祖先毛皮颜色更深，C项中的The dark past既表明了北极熊祖先的外表特征，也暗含它们过去误入北极的历史。第二节(共5小题；每小题2分，满分10分)根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。You need to dress warmly when you play in the snow. And to get around in deep snow, you might need snowshoes.Animals need winter coats and snowshoes too.A musk ox (麝牛) wears two coats in winter. _31_ It keeps the inner coat of soft fur warm and dry. The furry undercoat falls off each spring and the ox grows a new one every winter.A snowshoe rabbit changes its coat to match the season. _32_ In winter it grows white fur to match the snow. It even has fur on the bottoms of its feet._33_ A seal (海豹) has an extra layer under its fur coat too. This thick layer of fat lies under the seals skin and is great at holding in heat, especially in the water.The Arctic fox has fur on the bottoms of its feet and one of the warmest double coats of any animal. But on very cold and windy days, it adds something. _34_A polar bears big feet act like snowshoes. _35_ The bottom of each foot is protected by fur and the fur helps the bear walk on the snowy ground.AIt can run very quickly.BDo you wear a sweater under your coat?CThey can move quickly across the snow.DThe outer coat reaches almost to the ground.EIt uses its thick tail like a scarf to cover its nose and face.FIn summer its brown fur helps it hide among dirt and rocks.GThey spread out the bears weight so it can walk easily on the snow.语篇解读：本文是一篇说明文。文章介绍了动物如何抵御寒冷以及在冰天雪地里行走。31选D根据空后一句“It keeps the inner coat of soft fur warm and dry.”可知，D项“外面的皮毛垂到地面”符合语境。D项中的outer coat与空后一句中的inner coat相呼应。32选F根据该空前的“changes its coat to match the season”和该空后的“In winter it grows white fur to match the snow.”可知，雪兔的皮毛为了和不同的季节保持协调而发生变化，因此F项介绍雪兔的皮毛在夏天时的情况符合语境。F项中的In summer和空后一句中的In winter形成对比。33选B根据该空后的“an extra layer under its fur coat too”可知，B项“你在外套里面穿毛衣吗？”符合语境。B项中的“a sweater under your coat”与空后一句中的“an extra layer under its fur coat”相呼应。34选E根据该空前的“it adds something”可知，北极狐的尾巴还可当作围巾使用，包裹鼻子和脸。故选E项。35选G根据该空前的“A polar bears big feet act like snowshoes.”可知，G项“北极熊宽大的脚可以分摊自身的重量并且保证它们在雪上轻松行走。”符合语境。故选G项。第三部分：语言运用(共两节，满分45分)第一节(共20小题；每小题1.5分，满分30分)阅读下面短文，从短文后各题所给的A、B、C和D四个选项中，选出可以填入空白处的最佳选项。My wife and I were hiking deep in the woods with our dog Lucca.
