Recovering from the crash nearly destroyed her, but she refused to let her injuries hold her back.To prove to herself just how unlimited her possibilities are, Ennis set a goal: become the first veteran (老兵)amputee to complete the Seven Summits-the highest mountain on each of the seven continents.But Ennis' climbing journey isn't just about the mountains. On each climb, she raises money in support of a different nonprofit."I realized that it was a pretty unique platform…whether it's the younger generation, men, women or wounded veterans, they can look to me in a different way,” Ennis told Connecting V ets. “It's just the highlight of everything I always wanted to do.”Ennis has climbed up five of the seven mountains. She's been on Everest for more than a month, adapting to the altitude and planning routes, and her team plans to summit(登顶)on May 15, 2019. It's a climb she has been preparing for three years, including a trip in 2017."Everest is the most important part of everything I have trained for," Ennis told Pensacola News Journal. "Every mountain teaches me something different. Now I have to use all of those skill sets to be able to deal with Everest. Should I summit, history will be made as the first woman above knee amputee to do so. Each individual, especially those with disabilities, should b e able to determine what they're able to do.”Ennis shares detailed updates on her blog, and will post again after the summit attempt.24. Why did Ennis decide to conquer the Seven Summits?A. To inspire others.B. To challenge herself.C. To show her strong will.D. To make her life colorful.25. What does Ennis do on her climb?A. She promotes environmental protection.B. She collects money for a nonprofit.C. She recovers from her injury.D. She communicates with fellows.26. When did Ennis start to prepare for Everest?A. In 2016.B. In 2017.C. In 2018.D. In 2019.27. What can we infer from paragraph 6?A. Ennis values the experience on every mountain.B. Ennis is confident that she will summit Everest.C. Ennis has been well trained due to some experts.D. Ennis is proud of her upcoming achievement.CWith self-driving vehicle technology rapidly advancing, many companies are turning to autonomous robots for the final leg of the delivery process, from the store or local distribution center to the customer. The latest to join the trend is e-commerce giant. Amazon. Following a successful eight-month test run in Snohomish County, Washington, the company's Scout robots have been making the rounds of Irvine, California, since August 6, 2019.The six-wheeled Scout is about the size of a large cooler with the capacity to carry small or medium-sized packages. The battery-powered vehicle, which moves at a regular walking pace, has been programmed to avoid pedestrians, animals, and unexpected obstacles, such as garbage cans. Its powerful sensors can also detect themovement of a car backing out of a driveway.To accelerate Scout's development and bring it nationwide sooner, the company has created several detailed virtual maps of American suburbs and conducted trial deliveries to homes there.Though Amazon has not shown how Scout ensures the delivery is picked up by the right person, it most likely requires the customer to apply a unique code, texted to them prior to the delivery, to unlock the store box. Also unclear is the number of deliveries Scout can complete before its battery needs to be recharged. Though the initial tests are being conducted with a human for company, the robot will be autonomous in the future. Its location，however, will be tracked at all times-if someone attempts to steal Scout, Amazon employees will be instantly sensed.However, the eco-friendly robots are unable to climb stairs or open gates, which means that they can only reach consumers who live on the ground level. Additionally, the robots are unable to leave packages at the front door if the customers are not home. Whether these problems get resolved remains to be seen. For now, it appears that humans will still be needed to achieve the ever-growing demand for home and office deliveries.28. What are many companies developing autonomous robots for?A. Final tests.B. The so-called last mile.C. Robots' safety.D. Delivery speed.29. What can we infer about Scout from paragraph 2?A. It looks like a cooler.B. It adjusts its speed accordingly.C. Its sensors play a key role.D. It will be widely used soon.30. What does the underlined phrase "prior to" in paragraph 4 mean?A. Before.B. After.C. In front of.D. Due to.31. From which is the text probably taken?A. A biology textbook.B. A health magazine.C. A newspaper.D. A travel brochure.DScientists say they have found high levels of small plastic particles(颗粒)in Arctic snow. Their findings provide more evidence that plastic is entering Earth's atmosphere and traveling great distances around the planet.A German-Swiss research team collected snow samples from the Arctic and other areas. They included northern Germany, the Bavarian and Swiss Alps, and the North Sea island of Heligoland. When the researchers examined the samples in a lab, they were surprised to find very high levels of microplastics.Microplastics are very small pieces of plastic. These plastic particles are generally smaller than 5 millimeters in length. Other studies have found microplastics in the environment. They come from the disposal and breakdown of man-made plastic products and industrial waste.The study found the highest levels of microplastics came from the Bavarian Alps. One snow sample(标本)from the area had 154,000 microplastic particles per liter. Samples collected from the Arctic had much lower levels. However, even samples from the Arctic contained up to 14,000 particles per liter.Earlier studies found signs of plastic in Arctic areas. Those microplastics were found in coastal areas, sea ice, the seafloor and the seawater's surface. The new study attempted to explore how some of the material could have been carried in the atmosphere. A limited number of earlier studies did find microplastics in the air of some cities. including Paris, Tehran and Dongguan, China.The research team discovered many kinds of microplastics. Some were from paints commonly used to coat the surface of automobiles and ships. A rubber-like substance was also found that could have come from vehicle or boat parts or packaging materials.While there is growing concern about the effect of microplastics on the environment, scientists are still studying their possible harmful effects on humans and animals.32. How did scientists feel when knowing the levels of microplastics in Arctic?A. Doubtful.B. Concerned.C. Excited.D. Astonished.33. Which is right concerning microplastics?A. Scientists are examining the exact level of microplastics.B. Scientists are reducing the concerns of microplastics.C. Microplastics have been discovered in Arctic for the first time.D. Scientists have researched about the spread of microplastics.34. What are scientists eager to uncover?A. The degree of influence on Dongguan.B. The influence of microplastic on humans.C. The content of microplastic in the seafloor.D. The measures to rid microplastic effectively.35. What is the best title for the passage?A. Microplastics around the WorldB. Microplastics, a New PollutionC. High Levels of Microplastics in ArcticD. Great Concern about Microplastics in Arctic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。

一、现代文阅读（36分）（一）论述类文本阅读（本题共3小题，9分）阅读下面的文字，完成1~3题。
“民生”，这几年已经成了社会生活中分外响亮的“主题词”。
政府出台“民生政策”之密集，媒体推出“民生话题”之深入，百姓关注“民生热点”之强烈，可谓前所未有。
如何使每一级政府的惠民之举，托起每一个百姓的幸福生活？显然，我们还有许多的结待解。
走进基层，常常遇到一些令人忧虑的现象。
民生是个“筐”。
看一看各地在抵抗金融危机中接连推出的刺激需的大手笔，看一看基层在跟进产业转移中争相展示的招商引资的新路数，其中究竞有多少是真正关乎民众切身利益的惠民工程，有多少是紧密呼应民众迫切需求的民生项目！一些地方向上汇报、对外宣传时，为了标榜自己的“高度重视”，竟然把高速公路、城市广场等基础设施投资都算作了民生工程。
民生是个“秀”。
“有粉搭在脸上”，这是许多官员的共通心态。
就谈新农村建设，不少地方忙于撤并村庄、洗脚上楼，简单地将城市样式照搬进来，靠近路边的建筑，还要涂脂抹粉，配上白墙红顶。
老百姓的谋生之道、生产方式还没有改变，就急着要在一个早上颠覆农民既有的居住文明和生活方式，于此，官员们有了迎接上级领导检查视察的“盆景”，有了自己表功炫耀的“面子”，甚至还有了其中房地产开发的“实惠”，老百姓却尝到了难言的苦果。
民生是个“痛”。
一些地方政府或盲目追求跨越发展，或急于拉动投资需求，或企图摆脱财政困境，提出加速城市化，让更多的百姓以承包土地换一纸户籍，尽快过上城市生活，享受公共服务，沐浴现代文明。
但是，他们并没有换位思考：农民到城里买不起房怎么办？找不到工作怎么办？子女就学遇到困难怎么办？民生是什么？不是口号，不是标榜，它是百姓的切身利益，是人民的幸福生活。

一、现代文阅读（36分）（一）论述类文本阅读（本题共3小题，9分）近年来，我国的城镇化进入快速发展阶段，城镇化率已从改革开放初期的不到20%，提高到目前的近60%。
但城市的快速发展与繁荣跟许多农村地区的凋敝与衰落形成了鲜明反差。
概括来说，我国城乡发展不平衡问题主要体现为以下几个方面：由于特定的历史和政治因素，我国形成了以城乡二元结构为基础的工业化和城镇化发展政策，强调优先发展城市工业，各种资源主要向城市集中，中国的城乡发展出现了一些突出问题；城乡之间基本公共服务设施与水平存在明显差距，农村基本公共服务建设落后，农村社会建设存在明显短板，城乡居民身份和地位出现分化。
如何打破城乡二元结构，改变不平衡的城乡发展格局，促进“三农”问题的解决已成为当前我们所面对的重大课题。
调整城乡不平衡发展的格局，克服城市发展优先的偏向，真正落实农业农村优先发展的原则和策略。
党的十九大报告明确指出“要坚持农业农村优先发展”，这是实施乡村振兴战略的重要方面，突显了我国对农业和农村发展前所未有的重视。
但要真正落实这一重大举措，首要的一点是，改革城乡发展不平衡的政策机制，加大对农村地区发展的投资和支持力度，使更多的城市资源和基本公共服务向农村延伸或倾斜，为农业和农村发展创造更有利的条件，提供更多的发展机会。
进一步变革城乡二元结构体制，进行机制和体制创新，打破城乡壁垒，激发乡村发展的活力。
可以说，我国城乡分割的二元结构是城乡不平等和城乡关系失衡的主要体制根源。
近年来，尽管在户籍制度、就业、社会保障与公共服务等方面进行了一系列重要改革，但由于城乡二元结构根深蒂固的影响，城乡居民在工作和生活的各个方面仍然受制于此。
