In 2012, he and his family were inspired to build and donate a bunk bed, one bed on top of the other,after learning there were local children who slept on the floor. Shocked to discover how widespread this need was in his community, Mickelson founded Sleep in Heavenly Peace, a nonprofit that builds and delivers beds to children in need.Bom and raised in Idaho, Mickelson, now 41, had a thriving career. He coached his kids’sports teams and fished in the nearby river. But when he met children who were sleeping on thefloor, his peaceful life changed course.Using safety guidelines and his daughter’s bunk bed as a model, Mickelson started buying wood and supplies to build beds with his own money. He recruited friends and family members to help around the holidays. As word spread, interest and involvement from his and other communities flooded—along with Mickelson's bunk bed output. "That first project, we built 11 bunk beds in my garage,” he said. "The next year, we did 15. Then it doubled every year. In 2017, we built 612 bunk beds.”With the motto "No kid sleeps on the floor in our town", the nonprofit and its more than 65 branches have built and delivered more than 1, 500 free beds to children across America. Butalong with the rapid growth, Mickelson was faced with a tough choice: advancing his career or his nonprofit. He chose the latter and went from making "great money to zero money" .

They volunteered to buy beds with their own money27. What is Mickelson's attitude to the nonprofit?A. Ambiguous.B. Defensive.C. CautiousD. PositiveCTrees, some of the tallest in the world, towered above Hannah Ginffiths and her colleagues each morning as they walked deep into the rainforest in the Maliau Basin in Bomeo, where they had set up a set of experiments to look at the ecological effects of small creatures : termites(白蚁)。

Positive.CTrees, some of the tallest in the world, towered above Hannah Griffiths and her colleagues each morning asthey tramped deep into the rainforest in the Maliau Basin in Borneo, where they had set up a set of experiments tolook at the ecological effects of smaller creatures: termites.Termites get a bum rap. They make headlines for chomping through billions of dollars of property each year inthe U.S.—and sometimes for literally eating money. And they are responsible for something like two percent ofglobal carbon emissions, simply as a result of their huge populations and preference for chewing throughcarbon-rich materials. A whole industry is aimed at killing them.But they play a key role in many natural ecosystems. Scientists have known for years that in tropical forests,termites chew up fallen leaves and dead wood, keeping the fallen material under control and letting nutrients fromthe dead material back into the system to be used by other plants, insects, and animals. But they didn’t knowexactly how important the insects were in keeping the forest healthy and functional, so they removed termites froma particular spot in the forest and saw how it responded.As luck would have it, Hanaha Griffiths and her colleagues started their experiment when the forest was hit byan exterme drought(干旱). During the non-drought years, they saw there wasn’t much difference between the normal plots and the ones where they’d removed the termites. But during the drought, the effects were marked. Where there were more termites munching through the drifts of leaf litter, the soil stayed moist and seedlingssprouted(抽芽), and the system was full of activity despite the long, hard dry spell.For Griffiths, it was only because they happened to study the drought that they could pick out the real importance of termites to the system, she points out. “A nd that rings alarm bells in my head,” she says, “be makes me think, well, what else don’t we know? If we start damaging biological communities, we donthat will do.”28.Which of the following best explains “a bum rap” underlined in Paragraph2?A.Unfair blame.B. Wide popularity.C. Public attention.D. Special preference.29.What have scientists learned about termites?A.They do serious harm to tropical rainforests.B. They contribute a lot to the ecosystem they live in.C.They act as food for other plants, insects and animals.D. They speed up the loss of nutrition in the rainforest.30. What can we infer from the finding of Griffiths’ experiment?A. Termites help rainforests survive climate change.B. Termites prefer drought years to non-drought ones.C. Termites benefit more than the forest during the drought.D. Termites enjoy eating tree seedlings during the drought.31. What does Griffiths tell us in the last paragraph?A. Termites are now in danger of extinction.B. Termites damage biological communities.C. We should think twice before damaging a species.D. We should study the drought to improve the system.DClassifying things is critical for our daily lives. For example, we have to detect spam mail, false political news. When using AI, such tasks are based on "classification technology" in machine learning -- having the computer learn using the boundary separating positive and negative data. For example, "positive" data would be photos including a happy face, and "negative" data photos that include a sad face. Once a classification boundary is learned, the computer can determine whether a certain data is positive or negative.However, the difficulty with this technology is that it requires both positive and negative data for the learning process, and negative data are not available in many cases. For instance, when a retailer (零售商)is trying to predict who will make a purchase, they can easily find data on customers who purchased from them (positive data), but itis basically impossible to obtain data on customers who did not purchase from them (negative data), since they donot have access to their competitors' data.According to lead author Takashi Ishida from RIKEN AIP, "Previous classification methods could not copewith the situation where negative data were not available, but we have made it possible for computers to learn with only positive data, as long as we have a confidence score for our positive data, constructed from information suchas buying intention or the active rate of app users. Using our new method, we can let computers learn a classifieronly from positive data equipped with confidence."According to Ishida, "This discovery could expand the range of applications where classification technologycan be used. Even in fields where machine learning has been actively used, our classification technology could be used in new situations where only positive data can be gathered due to data regulation or business constraints. Inthe near future, we hope to put our technology to use in various research fields, such as natural language processing, computer vision, robotics, and bioinformatics."32.How can the computer distinguish the positive data from the negative data?A.By learning the classfication boundary.B. By updating the data collected regularly.B.By separating happy faces and sad ones. D. By introducing classification technology.33.Why is the example mentioned in Paragraph 2?A.To prove how important the positive data are.B. To confirm that data on customers are complete.C.To argue that retailers get their competitors’ data.D. To explain why negative data are hard to acquire.34. What do the underlined words “new method” in Paragraph 3 refer to?A. Analyze buying intention.B. Building a confidence score.C. Assessing the active rate of app users.D. Equipping the computer with confidence.35. What can be the best title for the text?A. The history of Classification TechnologyB. Smarter AI: Machine Learning without Negative DataC. Bigger Data: Computers Assissting Language ProcessingD. The Comparison between Positive Data and Negative Data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。

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). Volunteers completed 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 casebecause 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.4. The underlined word in Paragraph 1 can be replaced by ________.A. challengedB. acceptedC. doubtedD. heard5. 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.6. 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.7. 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.CAfter almost an entire year of not going shopping and vacationing, you find the numbers reflected by your bank account meet your heart's desire.Now the most important question comes, what to do with the earnings? Should you fulfill dreams of the present, invest in preserving the future or perhaps keep saving it for a rainy day?Our elders always try to teach us the value of money and its moral weakness. One may be on a winning streak(连续成功)now,but it will not always be so. One will have days when there will be no sunshine but only rain. and their luck will hide behind those thick grey clouds. Save for those rainy days,they say.Do not spend too much,live within a budget,refrain fromcredit no matter how small and save for the future.Since the very first time we earn our own money from a summer job or earning our first salary, the lessons start. In fact, the pocket money that we receive when we are children begins the process of learning how to best manage one's money.People often think like this-one day when I have enough money, I will travel the world. Then, once we do earn enough money, tomorrow's plans start shadowing our present ones. However, is it wise to keep living for that future? Will we still enjoy or even be able to backpack in -our 50s? How will we ever enjoy our present if we areconstantly living for the future?Good questions, aren't they? 1 say travel but don' t let yourself run dry, treat yourself to some luxuries but also keep enough for your necessities, and enjoy your present but with a plan for the foreseeable future.Life is for the living. so live it sensibly.8.

And if you believe in eating French fries with your hamburger, you should worry more about carbonemission.It won't happen overnight, but as the planet’s climate changes, the growth cycles of main crops will all be heavily affected. Here are three of the crops that might not beat the heat.The potato actually needs a great deal of beauty rest to develop properly. “They need a cool nighttime temperature in order to start growing the tuber, the part that we eat,” Nelson says.Temperature and altitude are two primary concerns in coffee growth, and farmers are stuck between a rock and a hard place. “We know that coffee grows in a certain temperature range,” Nelson says. “They've been movingup the mountains, but at some point you run out of mountains to move up.” Higher-grade strains of Arabica coffee in Central American regions are at particular risk due to the need for lower growing temperature, especially since diseases and pests are also becoming more of a factor as temperatures rise.Even if you're looking at the direct effects of temperature alone, rice is in trouble. “As nighttime temperatures go up, the rice is going to have a problem flowering and won't make as many seeds,” Nelson says. In addition to this direct heat consequence, rising sea levels will flood many rice paddies and destroy water salinity levels, while droughts will lower production, raise prices, and further shame westerners who are clumsy with chopsticks to be able to clear their plates once a new grain is adopted.12. What is the closest meaning to the underlined word “emission” in Paragraph 1?A. Mixture.B. Pollution.C. Giving off.D. Going down.13. What does the potatoes' development need according to Nelson?A. Cool temperature at night.B. Sudden rise of the temperature.C. Enough water and salt.D. Much sunshine and fresh air.14. The rice is difficult to flower,probably because ________.A. sea levels go up suddenlyB. many seeds can't be producedC. the temperature rises at nightD. both temperature and altitude rise15. What is the best title for the text?A. How Does Global Warming Affect WesternersB. How Does the Cool Temperature Affect RiceC. What Is the Real Reason For Crops’ GrowthD.

That’s whyIndiabegan the Mid-Day Meal Scheme, the largest school-lunch program in the world. A free lunch encourages children to come to school and gives them the energy they need for learning. The program began in the 1960s.The kitchen in Vrindaban is run by the Akshaya Patra Foundation.

What will our cities be like? How much will artificialintelligence (AI) advance? Will global warming cause disastrous changes, or will we be able to engineer our way out of the climate change issues? Recently, the magazineBig Thinkasked top minds from a variety of fields to weigh in on what the future holds 40 years from now. The result is as follows.It's likely that by 2050 the majority of the people in the world will live in urban areas and will have a much higher average age than people today. Cities theorist Richard thinks urbanization will transform the education system of, making our economy less houses driven and removing the divisions between home and work.And rapidly advancing technology will continue ever more rapidly. Cities of the future won't look like “some sort of science-fiction fantasy”, but it's likely that technological advances and information overlays (VR and AR) will greatly change how we live. Self-driving cars will make the roads safer and provide faster transports. A larger version of driverless cars-driverless trucks — may make long-distance drivers out of date.Some long view predictions are completelydire. Environmentalist Bill says that if we don't make great progress in fighting global warming, it's likely we could see out-of- control rises in sea levels, huge crop shortfalls and wars over limited freshwater resources.In terms of how we will eat, green markets founder and “real food" supporter Nina believes that there will be more small milk processing plants and more regional food operations and we'll be healthier as a result.New York Timeswriter Mark thinks that people will eat fewer processed foods and eat foods grown closer to where they live.

We settled in our Airbnb accommodation, a cozy apartment, not long after we arrived inHobart, the capital city.After briefing us on the kitchen's facilities and the whereabouts of the bedroom and bathroom, our hostess Geraldine resumed her ironing work, which seemed to have been interrupted by our arrival.She was ironing what looked like security guard uniforms, and we soon found out that she worked in a local prison. And when she detected the curiosity in our tones, she offered a tour at the prison in her SUV. My friend and I exchanged a “this is incredible” look and said “yes” immediately.As we drove, she told us about the buildings that we were passing, the local market and how to get to MONA,Tasmania's well-known contemporary art gallery.And of course we got to hear some background information about the prison. According to our hostess, it currently holds Martin Bryant, a notorious criminal who cheated 35 people out of their property. We could see the high level of security from the layers upon layers of wires surrounding the gray structure inside.Getting to know a city in such a local way is something I would never be able to do by talking to a hotel receptionist, and this is what I like best about the apartment-sharing experience, not to mention the fact that it's usually cheaper than hotel rooms.But I'm fully aware of the risks of Airbnb, which is why I did my homework before booking online—I checked the reviews of the accommodation to avoid possible safety problems.That said, it is the mutual trust between a host and a guest that fascinates me—the interesting feeling of building a bond with a total stranger.4. Why did the hostess drive us to the prison?A. She planned to send the uniform to the prison.B. She found our curiosity about the prison.C. She wanted to show off her SUV.D. She needed to offer a tour for us.5. Which of the following can best explain the word “notorious” in Paragraph 5?A. Unfamiliar to everyone.B. Particularly disappointing.C. Well known for being bad.D. Extremely generous to others.6. Compared with hotels, what is the writer's favorite of the Airbnb accommodation?A. It is cheaper in most cases.B. It supplies a better living condition.C. It offers a much safer accommodation.D. It provides a chance to know local culture.7. What does the author think of finding accommodation on Airbnb?A. Disapproving.B. Supportive.C. Neutral.D. Doubtful.CHow much do consumers care about the carbon footprint of the products they buy? Would they care more if the goods were labeled with emissions(排放物)data?Does it matter at which stage in the lifecycle of a product the carbon is emitted? Research published in the International Journal of Environmental Policy and Decision Making offers a way to find out.Study participants view a carbon footprint label as similar to labels that have appeared on some existing products.The label shows the carbon dioxide emissions connected with their production, transportation, usage and disposal(清理), thus showing the buyer the likely effect on climate change of buying a particular product.In the first group of studies, the research team proved that carbon emissions and a carbon emissions label would indeed play a role in consumer product decisions, although not as great a role as price.In a second set of studies, the team found that emissions connected with usage were most important to consumers followed by the transportation and disposal stages.The carbon footprint of the producing process was considered less important to consumers than the other stages in the product's lifecycle because it is outside the consumer's control.That is, the participants felt they were less responsible for carbon emitted during producing process.Consumers value recycling a product, but the researchers found that, overall, the consumers would preferproducers to offset(补偿)carbon emissions rather than having toaddressthe problem directly themselves.Consumers are increasingly concerned with climate change problems, and already carbon labeling is appearing on some products."We find that participantsnot only take the carbon label into account when making product decisions, but they want detailed information on the label," the researchers explain.They suggest that companies should prepare for how carbon emissions labels might affect future consumer choice.8. Which of the following most affects consumer's choice?A. Labels.B. Price.C Packaging. D. Carbon footprint.9. About the carbon dioxide emissions in the product's lifecycle, which stage do consumers care most?A. Usage stage.B. Transportation stage.C. Disposal stage.D. Producing stage.10. Which of the following can best replace the underlined word "address"?A. Look into.B. Point out.C. Deal with.D. Run into.11. What can be inferred from the last paragraph?A. Companies should take carbonemissions more seriously.B. All products have been labeled with carbon emissions data.C. Producers will attach less importance to carbon emissions labels.D. Products labeled with carbon emissions data will have poor sales.DDo you ever listen to the songs that your parents like? Chances are that you don’t. You probably think the music that they like is old and boring and that the songs on your playlist are muchcooler. But scientists found that people’s music taste changes as time goes by. So it is likely that your own musical preferences will follow a similar path to your parents’, whether you like it or not.We used to think that culture and personality (个性) are the only reasons for different music choices. But researchers at the University of Cambridge noticed that as people enter into different age groups, their social environment changes, and so does their music taste. There are some musical periods that people go through in their life.The first period comes in the teenage years, during which people like strong music such as punk and rock, because teenagers tend to be aggressive or want to be independent.But as people move into early adulthood, their lifestyles change they want to build close relationships with others. As a result, they become fonder of contemporary music, such as pop and R&.B, which is usually uplifting and danceable.When middle age comes, most people have settled down. During this period, people prefer music, such as jazz and classical, as well as music like country, folk and blues.As for old people, they prefer old songs in their childhoods. They generally listen to relaxing music, such as country music and jazz music. But you must be questioning. “Aren’t there old people who are still interested in or even crazy about rock music?” Of course there are. But their reasons for listening to rock music may have changed. At that age people may listen to remind themselves of their youth.12. What do young people usually think of the songs their parents enjoy?A. They are actually less cool.B. They are worth listening to.C. They are especially serious.D. They are hard to understand.13. How many musical periods are there that people go through in their life?A. Two.B. Three.C. Four.D. Five.14. People who want to make friends mostly prefer ________.A. jazz musicB. country musicC. rock musicD. pop music15. What is the best title for the text?A. People Have Different Opinions on MusicB. People Listen to Music for the Same ReasonC. People’s Taste in Music Changes with TimeD. People’s Lifestyle Can Be Changed by Music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。

2019-2020学年合肥市实验学校高三英语二模试卷及答案解析第一部分阅读(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AA brother and a sister have been reunited (重逢) after more than 60 years, thanks to a letter in the Welwynand Hatfield Times. For years John Hannant kept a photo of his long-lost sister, hoping they would meet again.Margery, the eldest of three children, had signed up with the Royal Air Force as part of the war effort, when John was still a baby.The family lost touch and as many years passed only a single letter gave a clue to her whereabouts (下落). The clue was enough for a WHT reader to recognize Margery and put the family back in touch.John, 67, said he had been searching for a long time and a friend suggested writing to the paper.“That’s the one that made it, the letter to the paper,” he said. “It’s like a dream that comes true. The last time we ever heard from Margery was in 1953 after the terrible floods. She wrote home to know if we were all right.My sister Dorothy wrote back, but Margery had moved again and never got the letter.”Having retired from his job as a gardener at Park House, Mr Hannant decided to take action.He and his wife Doreen traveled to Margery’s home in Chelwood Avenue, Hatfield, which she shares with her husband Jack Cooke.Now 88, Margery was recovering from her heart operation, but immediately recognized her brother. John said, “It’s something I never thought that was going to happen but I always hoped it would.” AS well as finding his sister, John has also discovered he now has a nephew, a niece and six grandnieces and grandnephews.1.The headline of the news would be “________”.A.An unforgettable and moving experienceB.The Hannant family lost touch because of warC.A brother and a sister reunited after 60 yearsD.The importance of a letter to WHT2.Margery left her family because ________.A.she attended the air schoolB.she joined the Royal Air ForceC.she had to feed her familyD.a big flood hit her hometown3.Who helped the family reunite after many years?A.Margery’s husband Jack CookeB.The photographer of the photo of Margery.C.A neighbour of Mr Hannant.D.A reader of WHT.BA 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.”4. 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.5. 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’ DNA6. 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 impossible7. 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 effectCIt was once considered an important status symbol ---but having a home phone is increasingly seen asa white elephant. New figures show that one in five households no longer bother with a landline(固定电话),and almost a third of those that do never actually use it.The vast majority of people who still have a home phone ——72 percent ——say they only have it because it is part of their broadband package.But that's not the only reason to desert the home phone - 20 percent of those surveyed said that they were fed up with the number of cold calls and would-be scammers(诈骗者).Digital media expert Dr. Elinor Carmi said there was a generational and social divide in phone use. She explained:"If you,re young and have the mobility to go outside, you would rely on a mobile phone. But if you are older, disabled and perhaps poorer, our research shows you're more likely to use a landline. If you are richer, you will have access to more smart devices --- a smart TV, smartphone or laptop. But the poorer you are --- or if you are older, your use of these devices is more limited.”Last year, research from regulator Ofcom found that the amount of time spent on landline calls annually in theUKhad halved over just six years, to 54 billion minutes.

Different choices of phonesDI cried the first time I saw the Notre Dame(巴黎圣母院)years ago. I'd waited my entire life to see this great French architecture, and experienced it in its full glory on a bright sunny day. Last night, I again cried for the centuries-old church while watching it burn.I hadn't expected to spend my evening that way. My friend and I were having dinner at a cafe a block or so away from the Notre Dame, choosing to skip going inside with the intention to go back the next day.However, we heard that it caught fire, so we left the cafe and ran towards the church, following heavy smoke from it, and soon we joined a nearly silent crowd. Some were praying, some were crying, but most were staring indisbelief at the disaster happening before us. The fire continued to get worse. About 400 firefighters were working to control the fire. We could see their flashlights shining as they inspected the front from a balcony.The Notre Dame is part of the heartbeat ofParis, I reflected on the experiences I've had there, from attending a bread market out front to admiring the beautiful windows and architecture inside. It is a spot that helps makeParismagical. And here we were, watching it burn down. It was too much to handle, but it was impossible to look away.About 9:30 pm, the gathered crowd spontaneously(自发地)began to sing Hymns(圣歌)to the church. We sang along with the group, feeling at once less like tourists and more like members of them. I hadn't imagined all that before.For hundreds of years, the Notre Dame hasseen the most joyous and the most terrible moments in the lives of both France and her people. And when everyone was able to become one emotional force, it showed that even in her darkest hour, the Notre Dame was still there to bring us all together.12. Why did the author cry for the Notre Dame for the first time?A. She was touched by its greatness.B. She was sorrowful to watch it burn.C. She was regretful for missing its glory.D. She was excited about French cultures.13. What was the author doing when the Notre Dame caught fire?A. Heading for a faraway cafe.B. Visiting a church with a friend.C. Eating nearby with a friend.D. Wandering along the street alone.14. What can we know about the fire scene?A. People expressed their sadness in different ways.B. People were nervously rushing in different directions.C. Hundreds of volunteers joined in putting out the fire.D. Firefighters kept people away with shining flashlights.15. What impressed the author most?A. The church allowed visitors to gaingreat experiences.B. Many foreign tourists became members of the church.C. The church survived disasters for hundreds of years.D. People were brought together to sing to the church.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。

2019-2020学年合肥市第三中学高三英语二模试卷及参考答案第一部分阅读(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ASheffieldLincoln College of EnglishClasses for foreign students at all levels.3 months, 6 months, 9 months and one year course.Open all year.Small class (at most 12 students).Library, language laboratory and listening center.Accommodation (住宿)with selected families.25 minutes from London.Course fees for English for one year are£1,380 with reduction for shorter periods of study.1.This passage is probably taken from _______.A.an advertisementB.a noticeC.a posterD.a piece of news2.Who will be accepted by this college?A.Both foreign and native students.B.Only foreign beginners and the advanced.C.Foreign students from beginners to the advanced.D.Only foreign students advanced.3.While you stay there, who will take care of you?A.Your parents.B.Your classmates.C.The school where you study.D.The family you have chosen.BMy wife and I recently completed a day-long tour of the Great Wall with Jessie. In addition to being very knowledgeable about the history of theareas that we toured, she spoke excellent English and was able to answer all of our questions. Her driver was very experienced and polite, and we really enjoyed being able to have acustomized tour that avoided the tourist traps and forced shopping that seem to be a part of the larger group tours.The attractions themselves were fantastic. I was a little worried that the snowy weather might impact our trip to the Great Wall, but everything went fine, and there weren’t many people out at all that day. I suggest wearing strong shoes—the Great Wall is really a hike. And in snowy or rainy days, the surfaces are pretty slippery (滑的)! Seeing this area in winter was really unique, and the snow made for great pictures. Jessie kept us entertained with stories and facts about the construction of the Wall, and always pointed out great spots for taking pictures. Even though she’s in fantastic shape, she cared about our level of fitness and often stopped to let us catch our breath.When we got back to our hotel, Jessie gave us a great recommendation for dinner and some tips for our planned stops the next day. If I find myself in Beijing in the future, I will certainly be contacting Jessie for more tour opportunities, and I’ve already recommended her to some friends who are visiting the area later in the year. I can’t say enough about how kind and knowledgeable she was, and she really gave us a great tour experience.4. What can we infer about Jessie?A. She is a tour advisor.B. She is a tour guide.C. She is a foreign traveler.D. She is a skilled driver.5. When did the writer visit the Great Wall?A. In spring.B. In summer.C. In autumn.D. In winter.6. What did the writer think of his tour?A. Adventurous.B. Disappointing.C. Satisfactory.D. Improvable.7. What is the probable title for the text?A. A Wonderful Tour Day with JessieB. An Extraordinary Tour CompanyC. The Great Wall, an Excellent AttractionD. Jessie, a Kind and Knowledgeable GuideCIn the old days, when you had to drive to a movie theater to get some entertainment, it was easy to see howyour actions could have an impact(影响)on the environment. After all, you were jumping into your car, driving across town, coughing out emissions(产生排放)and using gas all the way. But now that we're used to staying at home and streaming movies, we might get a littleproud. After all, we're just picking up our phones and maybe turning on the TV. You're welcome. Mother Nature.Not so fast, says a recent report from the French-based Shift Project. According to "Climate Crisis: The Unsustainable Use of Online Video", digital technologies are responsible for 4% of greenhouse gas emissions, and that energy use is increasing by 9% a year. Watching a half-hour show would cause 1. 6 kilograms of carbon dioxide emissions. That's like driving 6. 28 kilometers. And in the European Union, the Eureca project found that data centers(where videos are stored)there used 25% more energy in 2017 compared to just three years earlier, reports the BBC.Streaming is only expected to increase as webecome more enamored ofour digital devices(设备)and the possibility of enjoying entertainment where and when we want it increases. Online video use is expected to increase by four times from 2017 to 2022 and account for 80% of all Internet traffic by 2022. By then, about 60% of the world's population will be online.You're probably not going to give up your streaming services, but there're things you can do to help lessen the impact of your online use, experts say. For example, according to Lutz Stobbe, a researcher from the Fraunhofer Institute in Berlin, we have no need to upload 25 pictures of the same thing to the cloud because it consumes energy every time. If instead you delete a few things here and there, you can save energy. Moreover, it's also a good idea to stream over Wi-Fi, watch on the smallest screen you can, and turn off your Wi-Fi in your home if you're not using your devices.8. What topic is the first paragraph intended to lead in?A. The environmental effects of driving private cars.B. The improvements on environmental awareness.C. The change in the way people seek entertainment.D The environmental impacts of screaming services.9. What does the underlined phrase become more enamored of" in paragraph 3 probably mean?A. Get more skeptical of.B. Become more aware of.C. Feel much crazier about.D. Get more worried about.10. What can we infer about the use of streaming services?A. It is being reduced to protect the planet.B. Its environmental effects are worsening.C. It is easily available to almost everyone.D. Its side effects have drawn global attention.11. Which of the following is the most environmentally-friendly?A. Watching downloaded movies on a mobile phone.B. Downloading music on a personal computer.C. Uploading a lot of images of the same thing.D. Playing online games over mobile networks.DA Singaporean company will feed airport food waste to mealworms before turning them into fish feed, aiming to cut the country's use of imported feed and offer a continuous alternative.Blue Aqua Internationalwill partner with Dnata, an air and travel services provider, to change organic waste at Singapore's Changi Airport into insect protein for aquacultural use, according to a statement Tuesday.The project looks to replace traditional fish and soybean meal as the main sources of protein for aquafeed. The insects will eat the food waste and change it into part of the body containing about 60 per cent protein. The dried baby worms will then be made into feed.These mealworms can be a continuous solution to several problems. Using a small land and giving out less carbon, they turn food waste into feed and offer an alternative source of protein. Ynsect SAS, a small French business that keeps mealworms to feed fish and pets, attracted money from investors includingIron Manmovie actor Robert Downey Jr. in a round of fund-raising last year.The deal will give Singapore's farmers access to domestically produced animal feed, which is traditionally bought from abroad. The Southeast Asian nation imports more than 90 percent of its food and has set a goal to produce a third of its food locally by 2030. It also aims to achieve a general recycling rate of 70 per cent by then. Presently, less than 20 per cent of Singapore's food waste is recycled.As part of the partnership, Dubai-based Dnata will add Blue Aqua to its list of suppliers to buy locally farmed seafood for its catering service.12. What is the function of mealworms?A. To cut the use of imported fish feed.B. To eat food waste and make fish feed.C. To domestically produce animal feed.D. To replace traditional fish and soybean meal.13. What does Paragraph 4 mainly talk about?A. The producers of the feed.B. The purpose of the projectC. The advantages of the project.D. The composition of the feed.14. What can we infer about Singapore from Paragraph 5?A. It is a rich country.B. It is short of self-produced food.C. Its recycling rate is very high now.D. Its farmers don't support the deal.15. What is the text mainly about?A. A new way to produce fish feed.B.An introduction to a company.C. A plan to reduce food waste.D. A deal to protect farmers.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。

AYou might have heard a lot about ancient towns and ancient cities in China. Here, we list several of the most beautiful ancient villages in China.Baoshan Stone City, Yunnan ProvinceBaoshan Stone City was built on a huge mushroom-shaped rock, and only has about one hundred houses. The houses are laid out in an orderly way, built on the rock, and linked by stone steps. The Naxi people there still lead an original life and grow crops in terraces (梯田); you can experience the colorful culture of the Naxi ethnic (民族的) group there.Tuvas Village in Kanas, XinjiangKanas Tuvas Village is near the mysterious Lake Kanas. The small village is located in a valley, and only has about 80 houses. These Swiss-style wooden houses are all surrounded by wooden fences. Tuvas is an ancient minority group.

They were originally built to defend their homeland.C. They are still cut off and difficult to access nowadays.D. They are the ethnic villages with unique architecture.BA simple project to help a family in need stopped Luke Mickelson in his tracks. In 2012, he and his family were inspired to build and donate a bunk bed, one bed on top of the other, after learning there were local children who slept on the floor. Shocked to discover how widespread this need was in his community, Mickelson founded Sleep in Heavenly Peace, a nonprofit that builds and delivers beds to children in need.Born and raised in Idaho, Mickelson, now 41, had a thriving career. He coached his kids’ sports teams and fished in the nearby river. But when he met children who were sleeping on the floor, his peaceful life changed course.Using safety guidelines and his daughter’s bunk bed as a model, Mickelson started buying wood and supplies to build beds with his own money. He recruited friends and family members to help around the holiday. As word spread, interest and involvement from his and other communities flooded—along with Mickelson’s bunk bed output. “That first project, we built 11 bunk beds in my garage,” he said. “The next year, we did 15. Then it doubled every year. In 2017, we built 612 bunk beds.”With the motto “No kid sleeps on the floor in our town”, the nonprofit and its mor e than 65 branches have built and delivered more than 1,500 free beds to children across America. But along with the rapid growth, Mickelson was faced with a tough choice: advancing his career or his nonprofit. He chose the latter and went from making “gre atmoney to zero money”. He’s never looked back. “I found that the need I have isn’t financial,” he said. “The need I have is seeing the joy on kids’ faces, knowing that I can make a difference.”24. Why did Mickelson set up Sleep in Heavenly Peace?A. To help the poor children.B. To make a big fortune.C. To inspire his community.D. To get more donations.25. What do we know about Luke Mickelson?A. He had his own fish farm.B. He changed his career from time to time.C. He used to sleep on the floor when he was a kid.D. He originally had a relaxing and pleasant life.26. How did other people react to Mickelson’s project?A. They showed little interest in it.B. They were supportive and involved in it.C. They were doubtful about the safety of the bunk bed.D. They volunteered to buy beds with their own money.27. What is Mickelson’s attitude to the nonprofit?A. AmbiguousB. Defensive.C. Cautious.D. Positive.CTrees, some of the tallest in the world, towered above Hannah Griffiths and her colleagues each morning as they walked deep into the rainforest in the Maliau Basin in Borneo, where they had set up a set of experiments to look at the ecological effects of small creatures: termites (白蚁).Termites get a bum rap. They make headlines for chewing up billions of dollars of property each year in the U. S. And they are responsible for something like two percent of global carbon emissions, simply as a result of their huge populations and preference for chewing through carbonrich materials. A whole industry is aiming at killing them.But they play a key role in many natural ecosystems. Scientists have known for years that in tropical (热带的) forests, termites chew up fallen leaves and dead wood, keeping the fallen material under control and letting nutrients from the dead material back into the system to be used by other plants, insects, and animals. But they didn’t know exactly how important the insects were in keeping the forest healthy and functional, so they removed termites from a particular spot in the forest and saw how it responded.As luck would have it, Hannah Griffiths and her colleagues started their experiment when the forest was hit by an extreme drought (干旱). During the non-drought years, they saw there wasn’t much difference between the normal plots and the ones where they’d removed the termites. But during the drought, the effects were marked. What they found was unexpected: in the termite-rich areas, the soil stayed slightly wet, more tree seedlings sprouted (抽芽), and the system was full of activity despite the long, hard dry spell.For Griffiths, it was only because they happened to study the drought that they could pick out the real importance of termi tes to the system, she points out. “And that rings alarm bells in my head,” she says, “because it makes me think, well what else don’t we know? If we start damaging biological communities, we don’t know what that will do.”28. Which of the following best e xplains “a bum rap” underlined in Paragraph 2?A. Unfair blame.B. Wide popularity.C. Public attention.D. Special preference.9. What have scientists learned about termites?A. They do serious harm to tropical rainforests.B. They contribute a lot to the ecosystem they live in.C. They act as food for other plants, insects and animals.D. They speed up the loss of nutrition in the rainforest.30. What can we infer from the finding of Griffiths experiment?A. Termites help rainforests survive climate change.B. Termites prefer drought years to non-drought ones.C. Termites benefit more from the forest during the drought.D. Termites enjoy eating tree seedlings during the drought.31. What does Griffiths tell us in the last paragraph?A. Termites are now in danger of extinction.B. Termites damage biological communities.C. We should think twice before damaging a species.D. We should study the drought to improve the system.DClassifying things is critical for our daily lives. For example, we have to detect spam mail (垃圾邮件), false political news. When we use AI, such tasks are based on “classification technology” in machine learning—having the computer learn, using the boundary separating positive and negative data. For example, “positive” data would be photos including a happy face, and “negative” data photos that include a sad face. Once a classification boundary is learned, the computer can determine whether a certain data is positive or negative.However, the difficulty with this technology is that it requires both positive and negative data for the learning process, and negative data are not available in many cases. For instance, when a retailer (零售商) is trying to predict who will make a purchase, they can easily find data on customers who have purchased from them (positive data), but it is basically impossible to obtain data on customers who have never purchased from them (negative data), since they do not have access to their competitors’ data.According to lead author Takashi Ishida from RIKEN AIP, “Previous classification methods could not cope with the. situation where negative data were not available, but we have made it possible for computers to learn with only positive data, as long as we have a confidence score for our positive data, constructed from information such as buying intention or the active rate of app users. Using our new method, we can let computers learn a classifier only from p ositive data equipped with confidence.”According to Ishida, “This discovery could expand the range of applications where classification technology can be used. Even in fields where machine learning has been actively used, our classification technology could be used in new situations where only positive data can be gathered due to data regulation or business constraints (限制). In the near future, we hope to put our technology to use in various research fields, such as natural language processing, computer vision, robotics, and bioinformatics.”32. How can the computer distinguish the positive data from the negative data?A. By learning the classification boundary.B. By updating the data collected regularly.C. By separating happy faces and sad ones.D. By introducing classification technology.33. Why is the example mentioned in Paragraph 2?A. To prove how important the positive data are.B. To confirm that data on customers are complete.C. To argue that retailers get their competitors’ data.D. To explain why negative data are hard to acquire.34. What do the underlined words “new method” in Paragraph 3 refer to?A. Analyzing buying intention.B. Building a confidence score.C. Assessing the active rate of app users.D. Equipping the computer with confidence.35. What can be a suitable title for the text?A. The History of Classification TechnologyB. Smarter AI: Machine Leaning without Negative DataC. Bigger Data: Computers Assisting Language ProcessingD. The Comparison between Positive Data and Negative Data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。
