海口市灵山中学2019—2020学年度高三年级第一次月考测试卷

2019-2020学年广西灵山县灵山中学高三英语月考试卷及答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30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ABritain's brilliant bridges have supported trade, brought communities together andare always the mostexciting part of the journey. These must-see bridges are now tourist attractions in their own right.Clifton Suspension Bridge, BristolDescribed byits legendary engineer Isambard Kingdom Brunel as “my first love, my darling", it was originally designed for horse-drawn traffic. Now, more than four million vehicles a year cross the 1,352ft-long toll（通行费）bridge over the Avon Gorge. The £ 1 toll for every journey pays for its maintenance. The history of the bridge, dating back to 1864, is kept alive through a programme of tours, events and exhibitions.Infinity Bridge, Stockton-On-TeesA pedestrian（行人）and cycle footbridge across the River Tees, its working title was the North Shore Footbridge, before it was given its grander name when opened in 2009. It is particularly incredible at night. The arches（拱形）of the bridge are also lit white and, on calm nights, their reflection in the water appears as an infinity（无穷大）symbol, thus inspiring the name which was chosen by the public.Tower Bridge, LondonAn engineering wonder built from thousands of tons of Portland stone and steel, it took construction workers eight years to complete. More than 120 years old, it's a popular tourist attraction, as well as a functional bridge. Visitors can take in the views over the capital, experience seeing London life through the Glass Floor, and visit the Victorian Engine Rooms.Iron Bridge, ShropshireOpened in 1781 , this is the first arch bridge in the world made out of cast iron. Recognised as one of the great symbols of the industrial revolution, it transformed the craft of bridge building and was a crucial factor in the development of the iron trade in Shropshire.1. Which bridge has the longest history?A. Clifton Suspension Bridge.B. Infinity Bridge.C. Tower Bridge.D. Iron Bridge.2. What can we know about Infinity Bridge?A. It was originally meant for pedestrains.B. The public give it two names.C. Ifs well worth visiting at night.D. Its arch is bigger than any other bridge's.3. What makes Clifton Suspension Bridge different from the other bridges introduced?A. It charges drivers for each passing.B. It offers walkers a good view at night.C. It was made from thousands of stones.D. It's a symbol of the industrial revolution.B“Heavy hearts, like heavy clouds in the sky, are best relieved by the letting of a little water, the French writer Antoine de Rivarol wrote. This love letter to the cleansing beauty of a good cry is a comforting thought at atime when the continuing stress of the COVID-19 has added heaviness to each of our lives.Scientifically, de Rivarol's poetic image doesn't, if you'll forgive the words used in the poem, hold water. There's limited research on crying, partly because of the difficulty of copying the behavior of real crying in a lab. But even within the previous studies, there's little evidence to suggest that crying provides a physiological cleansing of poisons in people's body.Psychologists believe the relief of a good cry connects with a different emotional process. “It seems that crying occurs just after the peak of the emotional experience, and crying is associated with this return to homeostasis: the process of maintaining a stable psychological state,” said Lauren Bylsma. He also said holding back tears can have negative physical consequences, including headaches and muscle tension. Such restriction can also limit our experiences of joy, gratitude and other positive emotions if we avoid acknowledging our feelings.For me crying has been easier said than done during the COVID-19. Psychologists say it's normal to feel stopped up by the stresses of the past year. We should find opportunities to release and process our emotions.Watching a tear-jerking movie, having an emotional conversation with a close friend, and writing in a journal are healthy ways toelicita cry. Physical activity like light-footed walking or even dancing can also signal our bodies to release some emotional tightness. We can then open up to the flow of feelings that leave us feeling lighter and refreshed—like a clear sky after a soaking rain.4. What is the weakness of the studies ever clone on crying?A. They were clone in a laboratory setting.B. They cared little about different forms of crying.C. They were always concentrated on people's daily life.D. They showed little about the positive physical effect of crying.5. What is the function of crying according to Lauren Bylsma?A. Curing people of their diseases.B. Keeping emotionally balanced.C. Producing negative mental results.D. Expanding people's experience of joy.6. What does the underlined word “elicit” in the last paragraph mean?A. Produce.B. Postpone.C. Control.D. Repeat.7. What are people advised to do according to the text?A. Learn to hold back their tears wisely.B. Share their emotion with their colleagues.C. Have a good cry when necessary.D. Try to avoid admitting our feelings.CA new study finds almost one third of the world’s population is overweight. Since 1980, obesity rates(肥胖率)in children and adults have doubled in 73 countries, making people more worried. And rates are increasing in many other countries. Obesity is increasing faster in children than adults in many nations, including Algeria, Turkey and Jordan, the report said. But the world's weight problem is growing in both rich and poor countries alike. Researchers say an increasing number of people are dying of related health problems in what they called a "disturbing global public health problem."Researchers studied health information from 1980 through 2015. They examined obesity rates, average weight gain in 195 countries. They found that obesity rates are three times greater among youth and young adults in countries like China, Brazil and India. Almost 108 million children and more than 600 million adults were found to be overweight. Egypt had the highest number of overweight adults in 2015. Vietnam had the least. In the same year, the United States had the highest number of overweight children, and Bangladesh had the least.Yet hunger remains a problem in many areas. The United Nations said that almost 800 million people, including 300 million children, go to bed hungry each night. Experts said poor diets and lack of physical activity are mainly to blame for the rising numbers of overweight people.Growing populations have led to rising obesity rates in poor countries. Often, poor people will eat processed(加工的) foods instead of choosing a diet rich in vegetables.The London-based Overseas Development Institute studied the price of food in five countries: Britain, Brazil, China, Mexico and South Korea. It found that the cost of processed foods like ice creamand hamburgers has fallen since 1990. But the cost of fresh fruits and vegetables has gone up.8. What do we know about obesity in the world?A. It is worryingB. It is given no attentionC. It has been successfully solvedD. It is more serious among old people9. Which country has the most overweight children in 2015?A. AmericaB. VietnamC. EgyptD. Bangladesh10. What is one of the reasons why people get overweight?A. HungerB. Poor dietC. Diets with vegetablesD. Eating too much fruit11. Which ofthe following can be the best title for the text?A. It’s Important to Have a Balanced DietB. How Can We Lose Weight and Keep Fit?C. Is It Necessary for Us to Eat Fresh Vegetables?D. Nearly One Third of People in the World Are Overweight.DLast summer, I spent four months working in France, where the company I was working for put me up in a house that didn’t have Wi-Fi. I wasn’t looking forward to it.I soon discovered, however, that living in a house without Wi-Fi was easier than I expected.Contact between my friends and family was significantly reduced to the odd text message here and there. I couldn’t enjoy my usual web browsing on BBC iPlayer, social media sites, keeping up to date with the news, or even wanting to know the opening hours of shops in the new area I was in.I didn’t, however, spend a full four months without connecting to a Wi-Fi network. It was only a five minute walk to the reception where I could connect for free and spend as much time online as I wanted to at my own leisure. It made me think , though , how unnecessary it can be , how unnecessarily we rely on it—how we perhaps rely on it too much. As a person, I was more sociable. I spent more time with my housemates instead of hiding behind a computer screen. I did other things that I wouldn’t necessarily have done if I could have browsed the web at my leisure. I read more, I cooked meals for my friends, and I even tidied up more often. Dare I say it; I learned how to live without Wi-Fi. Dare I say it; I found it was easier than I had imagined.12. What was the writer’s first feeling when finding her house had no Wi-Fi?A. Unexpected.B. Angry.C. Shocked.D. Depressed.13. How did the writer keep in touch with her friends and family without Wi-Fi?A. By writing regularly.B. By text message.C. By video calls.D. By telegram.14. What was the writer’s life like without Wi-Fi?A. Dull.B. Lonely.C. Active.D. Relaxing.15. What can be a suitable title for the text?A. A life without Wi-FiB. Different views on the InternetC. The disadvantages of Wi-FiD. How to use the Internet第二节（共5小题；每小题2分，满分10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。

互联网技术塑造了一种全新的时空结构一一虚拟时空，虚拟时空的首要变化表现为空间上的“去中介化”，互联网逻辑的空间拓展彻底摆脱了对空间近邻的依赖性，进而建构了一种没有中介的市场，市场结构变得极为简单。

正因为如此，按照互联网逻辑呈现的空间才具有一种流动性，互联网的技术特征能够围绕产品与服务的市场关系，对供给与需求进行空间上的“黏合”，从而实现了市场交易的“去中介化”，虚拟时空的另一个变化表现为时间上的“弹性化”，在信息技术范式和互联网逻辑的作用下，高度程序化的时间脉络变得富有弹性和机动，高度体系化的时间结构变成了时间碎片并且能够及时组合。

毫无疑问，虚拟时空的“去中介化”和“弹性时间”从根本上改变了工业化逻辑中时空事项的组织方式，但同时也重构了一种全新的时空事项结构，并成为“互联网+”的技术红利的结构性源头。

具体而言，“互联网+”的技术红利主要来自于虚拟时空作用于市场的技术效应（简称“虚拟时空”的市场效应）。

第一个效应是“去中介化”显著促进了市场规模的技术性扩展．“去中介化”意味着市场交易彻底摆脱了空间的障碍和对空间近邻的依赖性。

在虚拟的时空结构中，市场关系可以无限延伸，只要存在互补性的供给和需求，不管供求双方身居何处，互联网都能够通过技术性撮合，将受空间限制的潜在交易对象变为现实的交易伙伴。

因此，“去中介化”不仅重构了市场关系的空间特征，而且实现了市场规模的技术性扩张。

第二个效应是“去中介化”和“弹性时间”有效改善了市场交易的成本结构。

2019-2020学年广西灵山县灵山中学高三英语月考试题及答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30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AIt looks like 2017 is shaping up to be a record-breaking year in movie History. Here is a list of some of the year’s biggest blockbusters so far.Kong: Skull IslandA reboot (重启) of King Kong would normally get laughed at in this day and age, but it looks like this modem version of the story will be worth watching. With US actress Brie Larson and UK actor Tom Hiddleston in the mix, this film is set to be this year’s biggest monster tale.Release Date:3/10/17Beauty and the BeastDirector Bill Condon is bringing back a part of our childhood in live action, complete with the songs we all remember and love. With British stars Emma Watson and Dan Stevens leading thecast, the classic Walt Disney story already sounds like it’ll be a delight for both children and adults.Release Date:3/17/17The Fate of the FuriousThere was doubt that we’d even get a Fast 8, especially after the fitting ending US actor Paul Walker’s character was given at the end of Furious 7. Fans thought they’d never see Dom and the rest of the crew back in action, but thankfully, US star Vin Diesel himself confirmed that The Fate of the Furious is fueling up for another go.Release Date:4/14/17Spider-Man: HomecomingSpider Man is heading home to Marvel Studios for the first time. The movie will show us Peter Parker’s high school days, and will continue the threads we saw formed during his initial appearance in Captain America: Civil War. We know that Michael Keaton is playing The Vulture in this story, and that both Happy Hogan and Tony Stark, played by US actors Jon Favreau and Robert Downey Jr., are along for the ride.Release Date:7/7/171.Which of the following movies can’t you see on May Day?A.Kong: Skull Island.B.Beauty and the Beast.C.The Fate of the Furious.D.Spider-Man: Homecoming.2.What can we know about Beauty and the Beast?A.It is fueling up for another go.B.It is produced by Marvel StudiosC.It’ll show us Peter Parker’s school days.D.It’ll be enjoyable for both children and adults.3.What does the underlined word “cast” probably mean?A.Characters.B.Actors.C.Directors.D.Teachers.BPaper is an important part of modern life. People use it in school, at work, to make artwork and books, to wrap presents and much more. Trees are the most common material for paper these days.So how do people make paper out of trees today? People first cut trees, load them onto trucks and bring them to a factory. Machines cut open the outer coverings of the trees, and cut the trees into pieces. Those pieces are boiled into a soup. After that, it is hit flat, dried and cut up into sheets of paper.The entire process, from planting a small tree to buying your school notebook, takes a very long time. Just growing the trees takes 10 to 20 years.Making tons of paper from trees can harm the planet. Humans cut down 80, 000 to 160,000 trees around the world every day, and use many of them to make paper. Some of those trees come from tree farms. But people also cut down forests for paper, which means that animals and birds lose their homes.Cutting forests down also contributes to climate change, and paper factories pollute the air. After you throw paper, it often takes the paper six to nine years to break down. That's why recycling is important. It saves a lot of trees, slows climate change and helps protect endangered animals, birds and all creatures that rely on forests for their homes and food.So if paper isn't good for the environment, why don't people write on something else?The answer: They do. With computers, tablets and cellphones, people use much less paper than in the past. Maybe a day will come when we won't use paper at all — or will save it for very special books and artworks.4. What can we know about making paper out of trees?A. It costs much money.B. It takes a lot of time.C. It is very easy and fast.D. It is dangerous and difficult.5. What is the impact of paper production?A. It promotes the recycling.B. It does harm to the environment.C. It slows down the climate change.D. It protects the animals from losing homes.6. How will we use paper someday in the future according to the text?A. Use it for books only.B. Use the recycled paper.C. Treasure it occasionally.D. Use it for artworks.7. What idea does the author want to express from the text?A. The influence of making paper on environment.B. The wonderful experience of making paper.C. The necessary process of making paper.D. The good reasons for making paper.CA world in which extinct creatures could be brought back to life came a step closer yesterday. Australian scientists have managed to extract a gene from a preserved sample of a Tasmanian tiger and make it active. Thebreakthroughhas left them dreaming that one day they will be able to recreate the animal, which died out more than 70 years ago. And if it can be done with the Tasmanian tiger, it may also be possible to resurrect (复活) creatures that have been extinct for far longer.“There used to be a time when extinction meant forever, but no more, ” said Professor Mike Archer. “We are now able to seriously challenge whether those animals that have gone for ever. What has been achieved is a very important step in bringing back those animals that are extinct. And while I think that technically it is still pretty difficult at the moment, we can now see the possibilities. I’m personally convinced that the Tasmanian tiger will be brought back to life in my lifetime.”The breakthrough came after nine years of experiments by scientists at the University of Melbourne, who extracted a gene from one of several tigers preserved in alcohol in a Melbourne museum. They removed the equivalent gene from a mouse embryo implanted the tiger gene and then watched as the mouse continued to grow normally, suggesting the tiger gene had been activated.Team leader Dr. Andrew Pask said it was the first time DNA from an extinct species had been used to “induce(引起) a functional response in another living organism”.However, the animal’s entire gene structure would have to be revived in the same way to even begin the possibility of bringing the Tasmanian tiger back from the dead.Mick Mooney, a wildlife officer ofthe Tasmanian Government, was worried that such developments could encourage people’s indifference to the protection of endangered species.“If people think that we can bring animals back to life after they’ve gone, they will start saying that there is nothing to worry about because we can fix it up later.”8. What does the underlined word “breakthrough” in the l paragraph refer to?A. Scientists have recreated new animals.B. Scientists have resurrected endangered animal.C. It has turned out that some creatures would not go extinct.D. A tiger gene has been extracted successfully and activated.9. Scientists are carrying out the experiments in order to ________.A. bring extinct animals back to lifeB. transplant the genes of tigers into other animalsC. find out what factors lead to the animals’ extinctionD. find a new way to extract animals’ DNA10. Mike Archer thinks that ________.A. scientists now have no technological difficulty reconnecting extinct animalsB. it’ll be a century or so before a Tasmanian tiger walks on the earth againC. humans have come closer in reconnecting extinct animalsD. reconnecting extinct animals is impossible11. We can learn from Mick Mooncy’s words that_________.A. he thought it unnecessary to worry about endangered animalsB. his opinion is in contrast with that of the Tasmanian GovernmentC. he thought people should be encouraged to protect endangered animalsD. he is concerned that bringing extinct animals back to life may have a negative effectDOne day when I was 5, my mother criticized me for not finishing my rice and I got angry. I wanted to play outside and not to be made to finish eating my old rice. In my angry motion to open the screen door (纱门) withmy foot, I kicked back about a 12-inch part of the lower left hand corner of the new screen door. But I had no regret, for I was happy to be playing in the backyard with my toys.Today, I know if my child had done what I did, I would have criticized my child, and told him about how expensive this new screen door was, and I would have delivered a spanking (打屁股) for it. But my parents never said a word. They left the corner of the screen door pushed out, creating an opening, a crack in the defense against unwanted insects.For years, every time I saw that corner of the screen, it would remind me of my mistake from time to time. For years, I knew that everyone in my family would see that hole and remember who did it. For years, every time I saw a fly buzzing in the kitchen, I would wonder if it came in through the hole that I had created with my angry foot. I would wonder if my family members were thinking the same thing, silently blaming me every time a flying insectentered our home, making life more terrible for us all. My parents taught me a valuable lesson, one that a spanking or stern (严厉的) words perhaps could not deliver. Their silent punishment for what I had done delivered a hundred stern messages to me. Aboveall, it has helped me become a more patient person and not burst out so easily.12. When the author damaged the door, his parents _______.A. scolded him for what he had doneB. left the door unrepairedC. told him how expensive it wasD. gave him a spanking13. How did the author feel every time he saw the damaged door?A. He felt ashamed of his uncontrolled anger at that time.B. He found that his family members no longer liked him.C. He found it destroyed the happy atmosphere at his home.D. He felt he had to work hard to make up for (弥补) the damage.14. The experience may cause the author _______.A. to hide his anger away from othersB. not to go against his parents’ willC. to have a better control of himselfD. not to make mistakes in the future15. What of the following is the main idea of this passage?A. Adults should ignore their children’s bad behavior.B. Parents shouldn’t educate their children.C. What is the best way to become a more patient person?D. Silent punishment may have a better effect on educating people.第二节（共5小题；每小题2分，满分10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。

Knightscope says the goal is to reduce crime by half in areas the robots guard.William Santana Li is the chief executive officer of Knightscope. He says，"These robot security guards will change the world. Our planet has more than seven billion people on it. It's going to quickly get to nine billion people. The security equipmentthat we have globally is just not going to develop that fast. The company's Autonomous Data Machines can become the eyes and ears of law enforcement（执法）.""You want them to be machines plus humans. Let. the machines do the heavy and sometimes dangerous work and let the humans do the strategic decision-making work，so it's always working all together."The machines do not carry weapons but they have day and night video cameras which are able to turn 360 degrees and can also sense chemical and biological weapons.Some people may become concerned about their privacy, especially in connection with the video recordings. Some people may worry that such recordings will appear on the Internet. Eugene Volokh, a law professor at the UCLA School of Law, says the machines have to be used in the right way and it will be interesting to see how state laws deal with this kind of video.William Santana Li says there is a long waiting list for the robots in theUS. Workers in the company are working overtime to meet the demands of the market. At least 25 other countries are also interested in these robot security guards.1. What can this new tool do for humans?A. Make strategic decisions.B. Keep watching day and night.C. Carry heavy weapons.D. Stop crime autonomously.2. Why are some people worried about the new robots?A. Their privacy may be let out.B. The robots are very expensive.C. Robots will replace humans.D. They will be out of work soon.3.

Security Robots Could Help Cut CrimeBA nurse has fulfilled (实现) a promise she made to her patient four years ago to one day attend her daughter's graduation from nursing school.Edina Habibovic, 22, graduated from Chamberlain University's College of Nursing in 2020. Her mother, Sevala Habibovic, 46, died in2017 after a two year fight with breast cancer.“I thought the medical field wasn't for me. Then, my mom got sick and I had all the experience going in and out of the hospital, ” Edina toldGood MorningAmerica. “When my mom passed away, I thought, ‘I want to dothis.’”she said.Sanja Josipovic, who at the time worked as a home health nurse with Northwestern Medicine in Winfield, Illinois, cared for Sevala inside her home. They often chatted and shared the latest news with each other over six months of care.“She was most worried about Edina because she was young and hadn't finished school yet, ” Sanja said. “We are like sisters; we care about and trust each other. She was a powerful and strong minded woman. She wasn't scared to die; she was just worried about her kids and husband.”Edina said her mother lived for being with her family and taking care of people. “When Sanja was working, my mom would still try to make her something to eat, no matter how sick she was, ” Edina added.

Maria really liked some things about the city, but she missed her house and yard in the countryside.One day, Maria was in her flat building when she noticed her neighbor, Mrs. Garcia, carrying a gardening tool and a bag of soil. Maria wondered how Mrs. Garcia was able to garden in the city.“My mom used to grow the most delicious vegetables, and I know she misses her garden now that we don’t have a yard,” said Maria.Mrs. Garcia laughed. “I’ll show you,” she said.Maria thought that Mrs. Garcia would take her to the park, but she took her to the roof. When the door opened, Maria was surprised to see rows of flowers and vegetables on the roof.“What a wonderful garden!” said Maria.Mrs. Garcia told Maria that for a long time the roof was just an empty space. Then some of the people in the building asked the owners to turn it into a community garden. The building owners liked the idea because theplants not only helped to keep the air clean, but they also helped to keep the building cooler during warmer weather.“I plant flowers in my own place,” Mrs. Garcia said, “but you would be surprised by how different the plants are up here. Some people grow vegetables just like your mom. You can do some of the same things in the city as in the countryside. You just have to be creative!”8. Where did Mrs. Garcia take Maria to one day?A. The park.B. The roof.C. The garden in front of her house.D. The countryside.9. Which of the following is NOT the good side of the community garden?A. It made the building stronger.B.

What is the best title for this passage?A. A Creative LadyB. An Empty RoofC. A Rooftop GardenD. A Special BuildingDFrom Mozart to Metallica, tons of people enjoy listening to various types of music while they paint, write, or draw. Most believe that music helps increase creativity, but an international study conducted by English and Swedish researchers is challenging that view. The study results wereechoedby scientists fromLancasterUniversity, and theUniversityofGavle, saying their findings show music actually weakens creativity.To reach their conclusions, researchers had volunteers complete verbal problems designed to inspire creativity while sitting in a quiet room, and then again while music played in the background. They found that background music significantly weakened the volunteers’ ability to complete tasks connected with verbal creativity. The team also tested background noises like those commonly heard in a library, but found that such noises had no influence on subjects’ creativity.The tasks were simple word games. For example, volunteers were given three words, such as dress, rise, and flower. Then, they were asked to find a single word connected with all three that could be combined to form a common phrase or word. The single word, in this case, would be “sun” (sundress, sunrise, sunflower). Volunteerscompleted the tasks in either a quiet room, or while listening to two different types of music: rock music or light music“We found strong evidence of weakened performance when playing background music in comparison to quiet background conditions,” says co-author D. Neil McLatchie ofLancasterUniversity. He and his colleagues find that music negatively influences the verbal working memory processes of the brain, preventing creativity. Also, as far as the library background noises having seemingly no effect, the study’s authors believe that was the case because library noises create a “regular state” environment that doesn’t affect concentration.“To conclude, the findings here challenge the popular view that music increases creativity, and instead show that music, whatever type it is, is always a disadvantage for creative performance in problem solving,” the study reads.12. The underlined word in Paragraph 1 can be replaced by ________.A. challengedB. acceptedC. doubtedD. heard13. What were the volunteers asked to do in the study?A. To play music.B. To combine given words.C. To create new words.D. To connect words with music.14. What can we infer from the study?A. Quiet background inspires creativity best.B. Library noise does no harm to creativity.C. Music has a bad effect on language ability.D. Music types matter in creative performance.15. Which is the main idea of the passage?A. Quiet Environments Prevent Concentration.B. Background NoiseAffects Concentration.C. Composing Music Weakens Creativity.D. Listening to Music Reduces Creativity.第二节（共5小题；每小题2分，满分10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。

But when that single tree is part of a small forest, it creates a considerable cooling effect. According to a study published today in the Proceedings of the National Academy of Sciences, trees play a big role in keeping our cities cool.According to the study, the right amount of tree cover can lower summer daytime temperatures by as much as 10 degrees Fahrenheit. And the effect is quite noticeable from neighborhood to neighborhood, even down to the scale of a single city block. “We knew that cities are warmer than the surrounding countryside, but we found that temperatures vary just as much within cities,” says Monica Turner, a professor in the department of Integrative Biology, Wisconsin-Madison University and a co-author of the study.With climate change making extreme heat events more common each summer, city planners are working on how to prepare. Heat waves drive up energy demands and costs and can have big human health impacts. One potentially powerful tool, the study's authors say, are organisms that have been around long before human civilizations could appreciate their leafy benefits. And those trees may be the secret to keeping the places we live livable.Essentially, says Turner, roads, sidewalks and buildings absorb heat from the sun during the day and slowly release that heat at night. Trees, on the other hand, not only shade those surfaces from the sun's rays, they also release water into the air through their leaves, a process that cools things down.To get the maximum benefit of this cooling service, the study found that tree cover must be more than 40percent. In other words, an aerial picture of a single city block would need to be nearly half-way covered by a leafy green network of branches and leaves.4. What can we infer from Paragraph 2?A. Temperatures in cities mainly depend on their green coverage.B. People living and working in cities must plant trees in summer.C. Cities are warmer than the countryside because they don't have trees.D. An area with more trees can be cooler than the other parts within a city.5. Which of the following problems is caused by extreme heat events?A. Severe damage of city facilities.B. Serious human health problems.C. Residents' growing demands for plants.D. Unnecessary waste of energy resources.6. Why are trees crucial to cities?A. They help shade and cool the cities.B. They make urban scenery beautiful.C. They build up city cooling systems.D. They essentially block and release heat.7. What can city planners conclude from the study?A. They should publish the study in a newspaper.B. They should educate citizens to protect forests.C. They should plant trees on roads and sidewalks.D. They should cover nearly half the city with trees.CAvi Loeb, a scientist, believes that we are not alone in the universe. The belief fits withLoeb's alien spaceship theory that at least one alien spaceship might be flying over the orbit of Jupiter, which won the international attention last year.Astronomers inHawaiifound the first known interstellar object in late 2017. It was a bit of light moving so fast past the sun that it could only have come from another star. Almost every astronomer on the planet was trying to figure out how the object, called “Oumuamua” got to our far-away part of the Milky way galaxy. “One possibility is that ‘Oumuamua’ is debris from an advanced technological equipment,” Loeb said. “Technology comes from another solar system just showed up at our door. ”“‘Oumuamua’ is not an alien spaceship,” Paul Sutter, another scientist wrote. He suggested Loeb was seeking publicity. Most scientists think “Oumuamua” is some sort of rock. They think it could be an icy wandering comet.Loeb says that “Oumuamua's” behavior means it can't be a block of rock shaped like a long photo. He thinksit's more likely an object that's very long and thin, perhaps like a long pancake or a ship's sail. Loeb says that if someone shows him evidence thatcontradictshis beliefs, he will immediately give in.Loeb believes himself a truth-teller and risk-taker in an age of very safe, too-quiet scientists. “The worst thing that can happen to me is that I would be relieved of my management duties, and that would give me even more time to focus on science,” Loeb says. He said he wouldn't mind giving up all the titles he had and returning to the Israeli farming village where he grew up.8. What does Loeb say about “Oumuamua”?A. It is an icy comet.B. It looks like a long photo.C. It is actually some sort of rock.D. It may come from another alien civilization.9. What does the underlined word “contradicts” in paragraph 4 probably mean?A.Goes against.B. Relies on.C. Turns to.D. Searches for.10. What do you think of Loeb?A. He is foolish.B. He is unsatisfied with his titles.C. He is a firm believer in scientific truth.D. He is uncertain about his career future.11. What's the best title for the text?A. Have Aliens Paid a Visit in Spaceships?B. Do We Really Know about Space Theory?C. Scientists Are Working on High TechnologyD. Astronomers Are Encouraging Space TravelDIn someareas ofCalifornia, it’s so dry that farmers aren’t willing to plant crops this season. Growers, north ofSan Francisco, have begun pulling out of local farmers markets.CountyLineHarvest, which farms more than 30 acres inPetaluma, hasn’t had enough water to grow all the peppers, lettuces and other produce for a long time, according to a video on its Instagram page. Nearby farms arc saying the same, emphasizing (强调) the effect of theextendeddry periods.Californiagrows a third of theUnited States' vegetables and two-thirds of the nation's fruits and nuts. If dry weather prevents farmers from growing plants, that could lead to pushing up the price of food that's already starting to affect theU.S.economy.“Due to severe drought, for the first time in 21 years, we will not be able to grow this summer inPetaluma,"CountyLinesaid in its post.Drew Lerner, president of World Weather Inc. inKansas, saidCalifornia“missed the rainy season" and won't see much moisture (水分) over the next several months.A La Nina weather pattern in the Pacific pushed winter storms north and away from the state, leaving it with less moisture than usual. AsCaliforniagets most of its water from winter storms, little relief is expected before October.That has left growers such as Shao Shan Fann in a bind. The business can’t offer the selection of Asian vegetables and Bay Area staples it usually grows at its Bolinas location, according to its website.Nearby, Green Valley Community Farm has access to only about 5% of the water it usually relies on, owner David Plescia said. He’s looking for new land with enough water to use, and also has a permit in the works to grow cannabis to make up for the lost income. If it doesn’t make it, he’ll leave the fields empty.“It’s part of our generation’s cross to bear, figuring out how to run small — or medium-scale farm businesses in this kind of atmosphere of highly variable rainfall,” Andrew said.12. What does the underlined word “extended” in the second paragraph mean?A. Hot.B. Short.C. Long.D. Wonderful.13. Which is the result if the dry weather stops famers from planting crops?A. Theincreaseinthe priceof food.B. The growth of economy inU.S.C.Lessmoisture than usual.D. The low price of Asian vegetables.14. From what Andrew said, we can infer (推断) all of the following statements EXCEPT that________.A. The climate is not very goodB. It is part of the burden for people of his generationC. It is hard for him to run his farm businesses insuch bad climateD. He is sure that the serious drought will come to an end soon15. What does the passage mainly talk about?A. How do the famers run businesses inCalifornia.B. How does the owner look for new land with enough waterC. California farmers facing drought choose not to plant crops.D. The farm economy of theUnited Stateshas changed a lot.第二节（共5小题；每小题2分，满分10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。
