2019-2020学年威海市第十五中学高三英语一模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AWhen it comes to the greatest inventions of the world, China’s name is sure to be mentioned several times. There are hundreds of things which were invented by the Chinese.AlcoholShocked? I was because when they said alcohol I thought about either the US or the UK. China had never crossed my mind. In China, alcohol was made by two legendary persons named Yi Di and Du Kang who belonged to the Xia Dynasty. This period was about 2000 BC - 1600 BC. Research says that in ancient China, beer with 4% alcoholic content was widely consumed by people.TeaChina is the proud inventor of tea which was first drunk by Shen Nong, a Chinese emperor around 2737 BC. Tea production was rapidly developed, making tea a popular drink during the Tang and Song Dynasties.The Mechanical ClockHave you ever wondered what on earth we would be doing without any idea of time? A clock really is an invention without which things were incomplete. The credit of making the first mechanical clock goes to ancient China. The first mechanical clock was invented by Yi Xing in the Tang Dynasty. This was during 618 and 907.Silk FabricSilk, the favorite fabric of many girls out there, is also a Chinese invention. Although we all know that silk is made by silkworms, it was Chinese people who first invented a way to harvest the silk and then use it to make clothes. The oldest silk which has been found so far is in Henan Province and dates back to 3630 BC.1.We can learn from Paragraph 2 that ________.A.people in the US like alcoholB.beer was popular in the Xia DynastyC.Yi Di and Du Kang invented alcohol by accidentD.the author didn’t know alcohol is a Chinese invention2.The author asks the question in Paragraph 4 to show ________.A.ancient Chinese inventors were wiserB.many things in our lives are incompleteC.ancient Chinese people never wasted timeD.the invention of the mechanical clock is important3.Which of the following invention has a longer history?A.Tea.B.Alcohol.C.Silk fabric.D.The mechanical clock.BEach year, the women of Olney and Liberal compete in an unusual footrace. Dressed in aprons (围裙) and headscarves, they wait at both towns’starting lines. Each woman holds a frying pan with one pancake inside. At the signal, the women flip (轻抛) pancakes and they’re off!This “pancake racing” tradition is said to have started on Shrove Tuesday, 1445, in Olney. Shrove Tuesday is the day beforethe Christian season of Lent (大斋戒) begins. During Lent, many people decide to give up sugary or fatty foods.Legend says that in 1445, an Olney woman was making pancakes to use up some of her sugar and cooking fats before Lent. She lost track of time and suddenly heard the church bells ring, signaling the beginning of the Shrove Tuesday service. Realizing that she was going to be late for church, she raced out the door still wearing her apron and headscarf and holding her frying pan with a pancake in it. In the following years, the woman’s neighbors imitated her dash to church, and pancake racing was born.The rules are simple. Racers must wear the traditional headscarf and apron. They must flip their pancakes twice - once before starting and once after crossing the finish line. After the race, there are Shrove Tuesday church services. Then Liberal and Olney connect through a video call to compare race times and declare a winner.In both towns, the races have grown into larger festivals. Olney’s festival is an all-day event starting with a big pancake breakfast. Liberal’s festival lasts four days and includes a parade, a talent show, and contests that feature eating and flipping pancakes. Although the women’s race is still the main event, both towns now hold additional races for boys and girls of all ages.4. How did pancake racing start?A. A woman in Olney created it.B. Women made pancakes before Lent.C. A woman dashed to church with a pancake.D. People followed the suit of an interesting incident.5. What should racers obey during the race?A. They can wear fashionable headscarves and aprons.B. They must flip their pancakes once in the race.C. They must flip their pancakes at the beginning of the race.D. They can flip their pancakes in the middle of the race.6. What can we learn about the race from the last paragraph?A. People can show their talent in Olney festival.B. People can enjoy a one-day holiday in Liberal.C. The race is not only intended for women now.D. People can have a big pancake breakfast in both towns.7. What is the text mainly about?A. The origin of pancake racing.B. The history of pancake racing.C. The development of pancake racing.D. The introduction to pancake racing.CThe idea of growing food in a desert would make most people laugh but this is quickly becoming a reality. There are currently two desert farms in the world where quality vegetables are being planted cheaply and easily.Sundrop Farms, based in South Australia, uses experimental greenhouses to grow tomatoes, peppers and cucumbers. The biggest challenge of growing food in a desert, obviously, is the lack of available water. The researchers at Sundrop Farms have gotten aroundthis problemby using the sun to desalinate (淡化) sea water. It can also be used to control the temperature of the greenhouses.Without depending on limited resources such as land and fresh water Sundrop Farms has made farming a practice. This can increase the world’s food supplies. Another benefit ofthis kind of farming is that it can be done anywhere, thus reducing the costs of transporting food to distant locations. Yet another benefit is that it reduces the need for pesticides (杀虫剂).Another experimental desert farm is the Sahara Forest Project, which began in Qatar in December 2012. Greenhouses in the farm are cooled by saltwater. Solar power and other technologies are used together to help make vegetation (植被) grow in the desert environment. As deserts have expanded over recent years around the world due to global warming, this project could solve the problem.The result form the Qatar project were better than expected and in June of 2014, Jordan agreed to host another one. This will be much bigger than the Qatar project and the project members will have even more opportunities to test their experiments on a much larger scale. It is not clear yet that desert farming resents the future of farming but these projects have shown some success in the field.8. What does “this problem” in paragraph 2 refer to?A. Sea water is bard to purify.B. The desert is short of water.C. The temperature is high in the desert.D. Desert farms aren’t fit to plant vegetables.9. What is one of the characters of desert farming?A. It needs more pesticides.B. It saves delivery costs.C. It has a location limit.D. It solves food waste problems10. What can we know about the Sabara Forest Project?A. It lives up to expectationsB. It can help produce more foodC. It is started to prevent global warmingD. It uses technology to produce saltwater11. What can be inferred about desert farming from the last paragraph?A. It still has problems to solve.B. It represents the future of farming.C. Its early success has aroused interest in it.D. Its aim is to create more job opportunities.DPeople from Britain and Ireland first came to live in Australia in 1788. They brought different dialects (方言) of English with them. These different kinds of English began to mix and change. The newcomers soon began to speak with their own typical accent (口音) and vocabulary. More and more people came to Australia during the Gold Rush in the 19th and 20th centuries. Some came from Britain and Ireland; others came from non-English speaking countries. Australian English continued to grow and change.Australian English has also been influenced by American English. During the Second World War, there were many American soldiers staying in Australia. More importantly, American television shows and music have beenpopular in Australia since the 1950s.Australians use many words that other English speakers do not use. The famous Australian greeting, for example, is G’day! A native forest is called the bush and central Australia is called the outback. Many words were brought to Australia from Britain and Ireland. For example, mate means “friend”, and it is still used in Britain. Some of these words have changed in meaning. Some words have come from Australian original languages, many of which are names for animals, plants and places, like dingo and kangaroo.Australian spelling comes from British spelling. In words like organise and realise, -ise is the expected and taught spelling method. In words like colour, favourite, -ouris the normal, but nouns such as the Labor Party and Victor Harbor are spelled with -or. Program, on the other hand, is more common than programme.There are also differences in the definition (定义) of words Australians use in different parts of the country. For example, football means “rugby” in New South Wales and Queensland, but “Australian rules football" in everywhere else in Australia. In New South Wales, a swimming costume is called a cossie or swimmers, while in Queensland it is called togs and bathers in Victoria.12. What does paragraph 1 mainly talk about?A. Reasons why English is important.B. Different dialects of Australian English.C. Various aspects that Australian English has been influenced.D. Changes of the accent and vocabulary in English.13. According to the text, which of the following is spoken only by Australians?A. Mate.B. Outback.C. Program.D. Rugby.14. Which is the following can best describe Australian English?A. Confusing and interesting.B. Multicultural and creative.C. Crazy and boring.D. Unchangeable and mixed.15. What might be the best title for the text?A. The History of AustraliaB. The Birth of Australian EnglishC. The Development of Australian EnglishD Different Kinds of English Across the World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学年乳山市实验高级中学高三英语模拟试题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AIf you had the opportunity to live forever, would you take it? Keeping your body alive indefinitely still seems like an impossibility, but some scientists think that digital technology may have the answer: creating a digital copy of your “self” and keeping it “alive” online long after your physical body has ceased to function.In effect, the proposal is to clone a person electronically. Unlike the familiar physical clones — children that have identical features as their parents, but that are completely separate organisms with a separate life — your electronic clone would believe itself to be you. How might this be possible? The first step would be to mapthe brain.How? One plan relies on the development of nanotechnology (纳米技术). Ray Kurzweil — one of the kings of artificial intelligence — predicts that within two or three decades we will have nano transmitters that can be put into the bloodstream. Inthe capillaries (毛细血管) of the brain, they would line up alongside the neurons and detect the details of the cerebral (大脑的) electronic activity. They would be able to send that information to a receiver inside a special helmet, so there would be no need for any wires sticking out of the head.As a further step, Ray Kurzweil also imagines the nano transmitters being able to connect you to a world of virtual reality on the Internet, similar to what was shown in the film “Matrix”. With the nano transmitters in place, by thought alone, you could log on to the Internet and instead of the pictures coming up on your screen, they would play inside your mind. Rather than send your friends e-mails you would agree to meet up on some virtual tropical beach.Some peoplebelieve that they can enjoy life after death. But why wait for that when you could have a shot of nanobots (纳米机器人) and upload your brain onto the Internet and live forever as a virtual surfer?One snag: to exist on the net you will have to have your neural network parked on the computer of a web-hosting company. These companies want real money in real bank accounts every year or they will wipe your bit of the hard disc and sell the space to someone else. With your body six feet underground how will you pay?1. Which of the following statements is TRUE according to the passage?A. Nano transmitters can help map the human brain.B. Electronic clones recreate the original human body.C. Electronic clones may put their physical selves into movies.D. Nano transmitters use a helmet to detect the cerebral activities.2. What is the author’s attitude towards electronic clones?A. Optimistic and careful.B. Interested and unconvinced.C. Excited and confused.D. Assured and critical.3. The author asks “how will you pay?” at the end of the article, because ________.A. you can’t pay to exist on the Internet if you are physically deadB. you can’t pay for hard disc space if you don’t have a bank accountC. you can’t pay for a special service if too many people want to use itD.you can’t pay the web-hosting company if you don’t have a neural networkBThe Great Barrier Reef's outlook remains “very poor” despite coral (珊瑚) recovery over the past year, Australian government scientistssaid Monday, just days before a UNESCO ruling on the site's world heritage (遗产) status.The United Nations cultural agency recommended last month that the world's largest reef (珊瑚礁) system be placed on its endangered list because of damage to the corals largely caused by climate change.The Australian Institute of Marine Science (AIMS) said the corals were now in a “recovery window” after a decade of harmful heat stress and cyclones (旋风). But such opportunities were becoming rarer due to the influence ofclimate change, the government agency, which has monitored the reef for 35 years, said in its annual report released today. “The increasing emergence of climate-related extreme weather events and starfish outbreaks is causing more severe and frequent pressures, giving the reef fewer opportunities like this to recover,”CEO Paul Hardisty said. The scientists surveyed 127 reef sites in 2021 and found hard coral cover had increased at 69 of the 81 locations surveyed in the past two years.Separate scientific research released last October found the 2, 300-kilometre (1, 400 miles) system had lost half its corals since 1995, with a series of ocean heatwaves causing mass coral death.Britta Schaffelke, research program director at AIMS, said the latest findings provided a slight hope that the reef still has the power of recovering. But she added that its future is still very poor because of the dangers of climate change and other factors that are affecting the reef.UNESCO has urged Australia to take urgent climate action but the government has long resisted calls to commit to net zero emissions (排放) by 2050. The government has said it hopes to meet the target “as soon aspossible” without harming its economy, insisting dealing with climate change requires a global effort. The reef was worth about US $4. 8 billion a year in tourism for the Australian economy and there are fears that an “in danger” listing could weaken its tourist appeal.4. What is the major cause of the damage to the corals?A. The climate change.B. Lack of money.C. Over development.D. Too many tourists.5. What is mainly talked about in Paragraph 3?A. The result of the survey.B. The efforts AIMS has made.C. The slight chance of the recovery.D. The terrible situation of the climate.6. What is Britta Schaffelke's attitude towards the future of the reef?A. Unclear.B. Positive.C Intolerant. D. Anxious.7. What can we infer from the last paragraph?A. Australia wants to put the reef on the endangered list.B. The Australian government has ignored UNESCO's demand.C. Australia hopes to keep a balance between emission target and its economy.D. The Australian government refuses to take its share of responsibility of climate change.CWhen John was growing up, other kids felt sorry for him. His parents always had him weeding the garden, carrying out the garbage and delivering newspapers. But when John reached adulthood，he wasbetter off than his childhood playmates. He had more job satisfaction, a better marriage and was healthier. Most of all, he was happier. Far happier.These are the findings of a 40-year study that followed the lives of 456 teenage boys fromBoston. The study showed that those who had worked as boys enjoyed happier and more productive lives than those who had not. “Boys who worked in the home or community gained competence（能力）and came to feel they were worthwhile members of society, ” said George Vaillant, the psychologist（心理学家）who made the discovery. “And because they felt good about themselves, others felt good about them.”Vaillant’s study followed these males in great detail. Interviews were repeated at ages 25, 31and 47. UnderVaillant, the researchers compared the men’s mental-health scores with their boyhood-activity scores. Points were awarded for part-time jobs, housework, effort in school, and ability to deal with problems.The link between what the men had done as boys and how they turned out as adults was surprisingly sharp. Those who had done the most boyhood activities were twice as likely to have warm relations with a wide variety of people, five times as likely to be well paid and 16 times less likely to have been unemployed. The researchers also found that IQ and family social and economic class made no real difference in how the boys turned out.Working—at any age—is important. Childhood activities help a child develop responsibility, independence, confidence and competence—the underpinnings（基础）of emotional health. They also help him understand that people must cooperate and work toward common goals. The most competent adults are those who know how to do this. Yet work isn't everything. As Tolstoy once said, “One can live magnificently in this world if one knows how to work and how to love, to work for the person one loves and to love one's work.”8. What do we know about John？A. He received little love from his family.B. He had few childhood playmates.C. He enjoyed his career and marriage.D. He was envied by others in his childhood.9. Vaillant’s words in Paragraph 2 serve as _______.A. a description of personal values and social valuesB. an analysis of how work was related to competenceC. an example for parents' expectations of their childrenD. an explanation why some boys grew into happy men10. Vaillant's team got their findings by _______.A. recording the boys' effort in schoolB. comparing different sets of scoresC. evaluating the men's mental healthD. measuring the men's problem solving ability11. What can be inferred from the last paragraph?A. Competent adults know more about love than work.B. Emotional health is essential to a wonderful adult life.C. Love brings more joy to people than work does.D.Independenceis the key to one's success.DScientists often compare coral reefs(珊瑚礁) to underwater rainforests, yet unlike the leafy plant base of a forest, corals are animals. The soft creatures are naturally half-transparent and get their brilliant color1 from algae(藻类) living inside them. When corals experience stress from hot temperatures or pollution, theyhaltthe interdependent relationship with algae, typically pushing them out and turning white. Corals are still alive when they are white, but they're at risk and many eventually die, turning dark brown.Scientists around the world are looking for means to protect and maybe increase corals. One common option is to create more protected areas — essentially national parks in the ocean. Beyond nature preserves, some conservationists are looking to more hands-on methods. One research center in the Florida Keys is exploring a form of natural selection to keep corals remaining. The reef system in the Keys has been hit hard by climate change and pollution, which is especially tough, because corals there help support fisheries worth $ 100 million every year.To keep the wild ecosystem alive, Erinn Muller, the center's director, and her team are harvesting samples of the corals that survived the environmental stress naturally, keeping them to make them reproduce, and then reattaching them to the reef. They have 46,000 corals on plastic frames under the sea. So far, the center has regrown over 70,000 corals from five different species on damaged reefs.In The Bahamas, Ross Cunning, a research biologist at Chicago's Shedd Aquarium, focuses on corals with genes that could make them natural candidates for restoration projects. He published a study of two Bahamian reefs, one that survived an extreme 2015 heat wave, and one that didn't. "We think their ability to deal with these higher temperatures is built into their genes," says Cunning. There's evidence of corals evolving more quickly to resist rapidly warming climate. The big question scientists need investigate, adds Gunning, is how much more heat corals can adapt to.12. What does the underlined word "halt" in the first paragraph mean?A. End.B. Develop.C. Strengthen.D. Weaken.13. What do Muller and her team do to save corals?A. Restore the damaged reefs.B. Grow corals by hand underwater.C. Create more protected areas.D. Move corals to unpolluted areas.14. What do Gunning's words suggest?A. Many corals have been genetically improved.B. Cooling down the waters is key to rescuingcorals.C. Reasons for corals surviving heat waves are shocking.D. The highest temperature corals can survive is unclear.15. Which can be a suitable title for the text?A. Relationship between corals and algaeB. Efforts made to save coralsC. Impact of climate warming on coralsD. Survival crisis faced by coral reefs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 here are four cities around the world that make for a great cold-weather destination:Prague,Czech RepublicWith its snow-capped spires and winding streets,Pragueis a fairytale city that remains ly tourist-free in winter.The amazing architecture looks even prettier under a sheet of snow, with one of the most beautiful areas being the old town, with its Romanesque vaults. Gas street lamps have been placed throughout the city center, adding a romantic color1 to evenings. Cafes here are ideal for escaping the bitter cold.Salzburg,AustriaWith its Christmas songs and traditional markets, this is a perfect city for a winter break. “Silent Night” was performed for the first time in thechurchofOberndorfon the border ofSalzburgon Christmas Eve in 1818.The city's main market is held in the shadow ofSalzburg'sHohensalzburgCastle, but the one held inMirabell Squareis especially popular with food lovers who come to taste local food such as halusky—pieces of dumpling mixed with fried bacon.Tromso,NorwayTromso is widely regarded asNorway's most beautiful city and is a base for spoiling the northern lights. There are several attractive museums, including thePolarMuseum, which offers an insight into the history of Arctic expeditions, and theTromsoMuseum, which is famous for its Sami exhibitions.Amsterdam,NetherlandsIn winter,Amsterdam' s museums are much less crowded, making it the time to visit attractions such as Rijksmuseum or the Anne Frank House. Built originally to house a circus, the Royal Carre Theater is more than 130 years old. Children will love the spectacular performances.1. What can you do inPrague?A. Enjoy the fascinating architecture.B. Taste local food halusky.C. Appreciate Sami exhibitions.D. Watch a circus performance.2. Where was “Silent Night” first performed?A. In thechurchofOberndorf.B. InHohensalzburgCastle.C. InMirabell Square.D. In the Polar Museum.3. Which city will you choose if you want to see the northern lights?A. Prague.B. Salzburg.C. Tromso.D.Amsterdam.BWhat will future schools look like in 100 years? Imagine future schools in which students are totally engaged in a class. They are concentrating on working together to solve real-world problems. They are self-driven and are coming up withamazing ideas on the spot. They are concerned with each other’s well-being as part of a team. Their concerns reach far beyond the classroom to others all over the globe.The school of the future will be an amazing melting pot of different peoples coming together to solve real-world problems.Will they even be called “schools” in the future?The teacher-student relationship is changing. Teachers are acting more as helpers rather than keepers of all knowledge. Students are driving their own education to the path that they feel best fits them. In the future, employers may not be as concerned with a diploma. They’ll look more at cases and examples of how students contribute to solving real-world problems. They’ll want to know how well they work in a team.What will problem-solving look like in the future?Information from the Internet is accessible everywhere and at unimaginable speeds. Kids are connected to news around the world in real time. Imagine someone could put out a request to the global community to help solve an issue in their own community! Classes can adopt an issue and work with other classes around the world in real time to create solutions.What will information look like in the future?It’s already everywhere. Users can get flooded by the constant flow of information. The need to understand what is true and what is not is important. The flipped classroom (翻转课堂) has already completely changed lecture-based lessons. It presents interesting content to students before they even come to class. They can access the Internet as many times as they want to review the lessons.4. What is the key message of the first paragraph?A. The things students will do in the future school.B.

To provide the lessons for students to study before or after class.C. To help students to keep in contact with the outside world.D. To help students to understand the most difficult content.CHave you ever been on social media and seen your favorite celebrity talking about a product? These promotions might not be totally random, and are actually seen as a vital part of the marketing process. The question is: How do social media influencers ‘influence’ what you buy?Human desire for status and making friends, combined with our need to belong to a group, makes us receptive to being ‘socially influenced’. Companies often use that desire to have a similar lifestyle to a celebrity we admire to sell or launch a product. So, what do these promotions actually do?Firstly, they can be used to build brand awareness. A social media influencer should have a strong understanding of the platform they operate on, and therefore can create appealing content that not only sticks to the brand image, but sparks their followers’ interests in a product they might never have seen before.Secondly, influencers can improve a company or product’s relationship with their customer base. According to InMoment’s 2018 US Retail CX Trends Report on customer loyalty, 77% of buyers have been brand loyal for more than ten years. This is also true of 60% of millennials. A popular celebrity can target key customers and talk or blog about a product, which can create an instant and lasting bond with them.Lastly, influencers can improve customer buying habits with seemingly ‘unbiased opinions’. We are more likely to respond to ‘peer recommendation’ than traditional ads, meaning the fact we see an influencer as a ‘friend’can make us less likely to be doubtful about what we are seeing.So, the next time you see a celebrity talking about a product, you might want to consider that this could be a carefully worked-out marketing strategy designed to target your core needs. If you find yourself examining a product you’ve seen on social media, you may well have been influenced.8. Why do companies invite celebrities to launch products?A. Because celebrities can improve the companies’ public images.B. Because consumers like to share similarity with celebrities.C. Because celebrities want to make more money.D. Because consumers can make friends with celebrities.9. According to the passage, which strategy is often used by influencers?A. Setting up operation platforms.B. Sending gifts to customers.C. Improving relationship with the company.D. Taking advantage of their popularity.10. To customers, the recommendations of influencers seem to be ________.A. offensiveB. subjectiveC. objectiveD. misleading11. The passage is mainly about ________.A. how social media make adsB. how social media influence our lifestyleC. how social influencers affect our buyingD. how celebrities earn fameDHardware in general,and smartphones in particular,have become a huge environmental and health problem in the Global South's landfill sites(垃圾填埋场).Electronic waste(e-waste) currently takes up 5 percent of all global waste,and it is set to increase rapidly as more of us own more than one smartphone,laptop and power bank They end up in places like Agbogbloshie on theoutskirts of Ghana's capital,Accra. It is the biggest e-waste dump in the world,where 10,000 informal workers walk through tons of abandoned goods as part of an informal recycling process.They risk their health searching for the precious metals that are found in abandoned smartphones.But Agbogbloshie should not exist.The Basel Convention,a 1989 treaty,aims to prevent developed nations from unauthorized dumping of e-waste in less developed countries.The e-waste industry,however,circumventsregulations by exporting e-waste labelled as "secondhand goods' to poor countries like Ghana,knowing full well hat it is heading for a landfill site.A recent report found Agbogbloshie contained some of the most dangerous chemicals.This is not surprising:smartphones contain chemicals like mercury（水银）,lead and even arsenic(砷).Reportedly, one egg from a free-range chicken in Agbogbloshie contained a certainchemical which can cause cancer and damage the immune system at a level that's about 220 times greater than a limit set by the European Food Safety Authority(EFSA).Most worryingly,these poisonous chemicals are free to pollute the broader soil and water system.This should concern us all, since some ofGhana's top exports are cocoa and nuts.Some governments have started to take responsibility for their consumers' waste.For example,Germanyhas started a project that includes a sustainable recycling system at Agbogbloshie,along with a health clinic for workers.However,governments cannot solve the problem alone, as there is an almost limitless consumer demand for hardware,especially when governments' green policies are focused on issues like climate change.Only the manufacturers can fix this.A more economically sustainable and politically possible solution is through encouraging hardware manufacturers to make the repair, reuse and recycling of hardware profitable,or at least cost-neutral12. What can we infer from Paragraph 2?A. Electronic waste requires more landfill sites acrossGhana.B. Electronic waste is too complex to get fully recycleC. Electronic products need to be improved urgentlyD. Electronic pollution is a burning question in Agbogbloshie13. What does the underlined word "circumvents"in Paragraph 3 mean?A. AbolishesB. TightensC. Brings inD. Gets around14. What should be the best concern according to the text?A. The thread of polluted food around the worldB. The damage of chicken’s immune systemC. The lack of diversity inGhana's exportsD. The violation of EFSA's standards15. What does the author think is the best solution to the e-waste problem?A. Manufacturers' developing a sustainable hardware economyB. Governments’ adjusting their green policies about e-waste.C. Reducing customers' demands for electronic productsD. Manufacturers’ urging the government to make effective policies to ensure more profit.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学年威海市第十五中学高三英语一模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AThere have been many great painters in the rich history of Chinese art. Here are four of the greatest painters from China.Li Cheng (919—967, Five Dynasties and early Song Dynasty)Li Cheng contributed greatly to one of the golden ages of landscape paintings in world history. During his time, he was considered the best landscape painter ever. He is remembered especially for the winter landscapes he created and for simple compositions of tall, old evergreens set against a dry landscape. Several of his paintings are in thin ink which gives them a foggy appearance.Fan Kuan (990—1020 , Song Dynasty)Fan Kuan began his career by modeling Li Cheng's work but later created his own style, claiming that the only true teacher was nature. His finest workTravelers among Mountains and Streamsis a masterpiece of landscape painting and many future artists turned to it for inspiration.Qi Baishi (1864-1957)One of the greatest contemporary Chinese painters, Qi Baishi is known for not being influenced by Western styles like most painters of his time. He can be considered as the last great traditional painter of China. He painted almost everything from insects to landscapes. He is regarded highly in Chinese art for the freshness that he brought to the familiar types of birds and flowers, insects and grass.Wu Guanzhong (1919—2010)Widely considered as the founder of modern Chinese painting , Wu Guanzhong has painted various aspects of China, like its architecture, plants, animals, people and landscapes. Wu went on to combine Western and Chinese styles to create a unique form of modem art. In 1992, he became the first living Chinese artist whose work was exhibited at the British Museum.1.What do we know about Li Cheng?A.He loved landscape paintings.B.He copied many artists' work.C.His work gained worldwide recognition.D.He was considered as Fan Kuan's teacher.2.What is the main feature of Qi Baishi's paintings?A.They have foggy appearances.B.They lack diversity in the theme.C.They come under Western influence.D.They show advanced traditional painting skills.3.What did the four Chinese painters have in common?A.They were all modern painters.B.They all created landscape paintings.C.They were all impacted by Western art.D.They were all pioneers intraditional art history.BOn World Oceans Day, which falls on June 8, the US National Geographic Society announced it would recognize the Southern Ocean in Antarctica, bringing the global total to five.Unlike the Arctic, Atlantic, Indian and PacificOceans—which are defined by the continents that bound them—the Southern Ocean is instead characterized by the Antarctic Circumpolar Current（南极洋流）. According to the National Geographic, the Southern Ocean includes most of the waters surrounding Antarcticaout to 60 degrees south latitude（纬度）."Encircled by the powerfully swift ACC, it is the only ocean to touch three others and to completely embrace a continent rather than being embraced by them," Sylvia Earle, a marine biologist and oceanographer, told the Daily Mail.Those familiar with the Southern Ocean know it's unlike any other. "Anyone who has been there will struggle to explain what's so charming about it, but they'll all agree that the glaciers are bluer, the air colder, the mountains more awful and the landscapes morecaptivatingthan anywhere else you can go," Seth Sykora-Bodie, a marine scientist at the National Oceanic and Atmospheric Administration, told National Geographic.National Geographic hopes their revised maps will bring public awareness to the region, thereby encouraging Southern Ocean conservation—but its significance is beyond that."We think it's really important from an educational standpoint, as well as from a map-labeling standpoint, to bring attention to the Southern Ocean as a fifth ocean," Alex Tait, National Geographic Society geographer, told The Post. "So when students learn about parts of the ocean world, they learn it's an interconnected ocean, andthey learn there are these regions called oceans that are really important, and there's a distinct one in the icy waters around Antarctica."4. Why is the Southern Ocean different from other oceans?A. It has never been explored before.B. It surrounds the Antarctic all around.C. It is enclosed by the fast-flowing ACC.D. It has ecologically distinct environment.5. What does the underlined word "captivating" in paragraph 4 probably mean?A. Strange.B. Unusual.C. Attractive.D. Informal.6. What does the National Geographic think of the Southern Ocean?A. It will be instructive for students.B. It will promote tourism development.C. It will encourage public to treasure water.D. It will draw scientists to study in the Antarctic.7. What is the best title for the text?A. World Oceans DayB. Revised Antarctic MapsC. Adding a New OceanD. New Discovery under the SeaCAddiction to smartphones will result in poor sleep, according to a new study.The study, published Tuesday in Frontiers in Psychiatry, looked at smartphone use among 1,043 students between the ages of 18 and 30at King's College London. Researchers asked the students to complete two questionnaires on their sleep quality and smartphone use, in person and online.Using a 10-question scale that was developed to judge smartphone addiction in children, nearly 40% of the university students qualified as "addicted" to smartphones, the study found. “Our findings are in agreement with other reported studies in young adult populations globally, which are in the range of 30-45%,” lead author Sei Yon Sohn and her co-authors wrote in the study. "Later time of use was also significantly connected with smartphone addiction, with use after 1 a.m. increasing a 3- times risk," the authors wrote.Students who reported high use of smartphones also reported poor sleep quality, the study found. That foils in line with previous studies that have found overuse of smartphones at night to be associated with trouble fallingasleep, reduced sleep duration (睡眠持续时间)and daytime tiredness. That's likely because use of smartphones close to bedtime has been shown to delay the body's normal sleep - and - wake clock.In fact, the No. 1 rule is "no computers, cell phones, and ipads in bed and at least one hour beforebed Dr. Vsevolod Polotsky, who directs sleep basic research, said in a recent interview. That's because "any LED light source from electronics (电子设备)may further hold back melatonin (褪黑激素)levels," Polotsky said. Melatonin is often referred to as a "sleep hormone," because we sleep better during the night when levels reach the top.“This is a cross-sectional study, and it cannot lead to any firm conclusions about smartphone use as the cause of reduced sleep quality, said Bob Patton, a lecturer in clinical psychology at the University of Surrey, via email.8. How did Sei Yon Sohn's team begin their study?A. By publishing researching papers.B. By responding to others’ concern.C. By collecting firsthand data.D. By turning to related experts.9. What did the study find about sleep quality and smartphone use?A. 30-45% of the university students are addicted to smartphones.B. High use of smartphones is related to poor sleep quality.C. Overuse of smartphones leads to shorter sleep duration.D. Use after 1 a.m. will result in smartphone addiction.10. What is Polotsky's opinion on electronics ?A. We should stop using them an hour before going to sleep.B. LED light source from them will delay normal sleep- and- wake clock.C. Reduced sleep quality has nothingto do with them.D. No electronics should be used in bed at any time.11. What can be a suitable title for the text?A. Say No to SmartphonesB. Sleep Quality Can Be ImprovedC. LED Light Source Causes Great HarmD. Smartphone Addiction Ruins SleepDHowdo you turn “dumb” headphones into smart ones? Rutgers engineers have invented a cheap and easy way by transforming headphones into sensors that can be plugged into (插入) smartphones, identify their users monitor their heart rates and perform other services.Their invention, called HeadFi, is based on a small plug-in headphone adapter that turns a regular headphone into a sensing device (装置). Unlike smart headphones, regular headphones lack sensors. HeadFi would allow users to avoid having to buy a new pairof smart headphones with sensors to enjoy sensing features.“HeadFi could turn hundreds of millions of existing, regular headphones worldwide into intelligent ones with a simple upgrade (升级),” said Xiaoran Fan, a HeadFi primary inventor.A Rutgers-led paper on the invention, which results in "earable intelligence", will be formally published in October at MobiCom 2021, the top international conference on mobile computing and mobile and wireless networking. Headphones are among the most popular wearable devices worldwide and they continue to become; more intelligent as new functions appear, such as touch-based gesture control, the paper notes. Such functions usually rely on aiding sensors, such as accelerometers, gyroscopes and microphones that are availableon many smart headphones.HeadFi turns the two drivers already inside all headphones into a versatile (多功能的) sensor, and it works by connecting headphones to a pairing device, such as a smartphone. It doesn't require adding aiding sensors and avoids changes to headphone hardware or the need to customize headphones, both of which may increase their weight and size. By plugging into HeadFi, a converted headphone can perform sensing tasks and play music at the same time.The engineers conducted experiments with 53 volunteers using 54 pairs of headphones with prices ranging from $2. 99 to $15 ,000. HeadFi can achieve 97. 2 percent to 99. 5 percent accuracy on user identification, 96.8 percent to 99. 2 percent on heart rate monitoring and 97. 7 percent to 99. 3 percent on gesture recognition.12. What does Xiaoran Fan think of HeadFi?A. Secure to operate.B. Simple to use.C. Easy to substitute.D. Convenient to store.13. What can we know about HeadFi according to the text?A. It can't work with headphones alone.B. It actually functions as a versatile sensor.C. It makes headphones larger and heavier than usual.D. It doesn't work when headphones are playing music.14.

2019-2020学年乳山市实验高级中学高三语文一模试题及答案一、现代文阅读（36分）(一)现代文阅读I(9分)阅读下面的文字，完成下面小题。

煮雪烹茶聂鑫森天一亮，雪光和曙光如瀑布般从窗外奔泻而入，洁白如羊脂。

昨夜的雪下得真大，飘飘洒洒，如鹅毛如柳絮。

北风微微，雪花落地的声音，如柔弦轻抚，入耳入心。

石上泉和夫人何洁早醒了，披着棉袄靠在床头。

空调喷吐着热气，暖融融的。

何洁说：“你昨夜总是翻身，睡不实。

”石上泉笑了，说：“这样的大雪，隔了十年才下一次，稀罕哩。

天气预报，分毫不差。

我们的北斗卫星，真是个好玩意儿。

”“怪不得你昨日黄昏，在园子里把那块青石板用清水洗了又洗，为的是干干净净地承接雪花。

”“对。

往年下雪，稀稀落落，敷衍了事。

我总想煮雪烹茶，过过瘾，这回可以如愿了。

”“也学《红楼梦》里的妙玉？”“那学不了。

园子里有梅树，也开了花，但要搭梯子去采撷梅蕊里的雪，一点点地收集。

可儿子家都在外地，我敢登梯取雪吗？古稀之人，不敢为风雅而冒险，伤了腿脚，不是苦了夫人吗？”何洁忍不住哈哈大笑。

“我该去舀雪了，你再休息会儿。

”“我得去为你准备早餐了，这叫同起同落。

”石上泉曾供职于市里的环境保护监测所，当了好多年的所长，职称是正研究员，得到同行赞誉的学术著作是《工业城市的环境治理》《大气污染的排放控制与净化》。

退休十年，石上泉不再管所里的事，侍花种草，读些闲书。

他虽是学工的，但兴趣却很宽泛，也练字也写诗。

曾有一家《老年报》的年轻记者打电话来预约采访，一听石上泉问是“哪位”，以为是他的儿子，忙礼貌地说：“请你爸爸接电话。

”石上泉一听，将错就错，说：“爸爸来不了啦！”记者又问：“他怎么啦？”石上泉说：“他早归山了，我是他的儿子石上泉！”记者一听，笑得差点儿掉了下巴。

石上泉提了一只细篾编织的小竹篮，拿了一把用南竹片削制的长竹刀，走到园子里去。

黑色的羽绒长大衣，黄色的羊毛围巾，枣红色的绒线老人帽，从上到下，饱满而明丽。

何洁说：“老来俏啊！”“谢夫人谬奖。

It's our pleasure to confirm this year’s Category Winners.First Novel Award WinnerBook: Eleanor Oliphant is Completely FineAuthor: Gail HoneymanEleanor is 31 years old; work finishes on a Friday and begins again on a Monday. Between, her only company will be two bottles of vodka and her own solitary, unique wit (机智). It is contentment, of a kind, but an unexpected shared experience suddenly opens the door to possibility. Challenging reader expectations with a living, breathing character, Gail Honeyman’s debut (初次登台、开张)is a funny and moving diamond.Biography Award WinnerBook: In the Days of RainAuthor: Rebecca StottThe Exclusive Brethren were aclosed community who believed the world is ruled by Satan.

He wanted to tell the story of their family who for generations had all been members of a fundamentalist Christian sect.Poetry Award WinnerBook: Inside the WaveAuthor: Helen DunmoreTo be alive is to be inside the wave, always travelling until it breaks and is gone. These poems are concerned with the borderline between the living and the dead — the underworld and the human living world – and the acutely intense being of both.Children's Award WinnerBook:The ExplorerAuthor: Katherine Rundell, Hannah HornFour children survive their aircraft plunging into the Amazon jungle, but for Fred and his friends it’s only the beginning of a cruel battle for survival.

Before me was a worn journal of thin and discolor1 ed pages. It was my grandfather’s journal and now belonged to my father. My grandfather had passed away in the months leading up to my birth. I never got to visit the places he had frequented and the people who had been a part of his life’s journey.I was now about to enter his world, through the words he had left behind. Within minutes, I wascaptivatedby the power of the written words. In the magical script (笔迹) before me, I was transported to another age when food was an everyday art, planned, prepared and enjoyed in the company of others, and a time when people had the heart to pause their own lives to embrace (拥抱) each other’s struggles. All this was conveyed to me in the beauty of the words that flowed together to connect with the writer’s mind and understand the world they lived in.That kind of writing seems to be lost on us today. We have gotten used to writing in bite-sized pieces for a public looking for entertainment, and hungry for information. No wonder, there are nearly 200 million bloggers on the Internet and a new blog is created somewhere in the world every half a second. Instead of adding to our collective wisdom, most of these writings reflectthe superficiality (肤浅) and impatience of our day and age.This not only robs us of the skill of writing impressive essays, it also prevents us from exploring what is indeedimportant. Writing humbles (使谦卑) us in a way that is vital for our character growth, by reminding us about the limits of the self and our appropriate place in the vast flow of life. Writing frees us by helping us explore the unknown so that we really open up to magic of the world around us. I saw all of this in the writing of my grandfather. And I’ve seen it again and again in the writings of the greatest thinkers of humanity. Their writing reflect deep thought on issues of human importance.4. The underlined word “captivated” in the second paragraph can be replaced by “________”.A. puzzledB. frightenedC. attractedD. defeated5. In the author’s grandfather’s age, people ________.A. lived a hard lifeB. cared about each otherC. were fond of writingD. treated food as an art6. The author begins the text with her grandfather’s journal in order to ________.A. show her respect to her grandfatherB. present the importance of good writingC. express her interest in reading as well as writingD. raise the problems with today’s writing7. In the last paragraph, the author is trying to _________.A. discuss what good writing is likeB. express her strong desire to learn writing skillsC. stress the effects of her grandfather’s journal on herD. show her admiration for her grandfather’s writingCPoaching and habitat loss have threatened Africa's two species of elephants, taking them closer toward the edge of disappearance, according to a new report released by the International Union for Conservation of Nature(IUCN).Before this update, Africa's elephants were grouped together and were evaluated as vulnerable by the IUCN. This is the first time the two species have been sorted separately. In the past, elephants were mostly considered as either Asian elephants or African elephants. Forest and savanna elephants were typically classified as subspecies of African elephants.The African forest elephant is now listed as critically endangered and the African savanna elephant asendangered. The number of African forest elephants fell by more than 86% over a 31 -year assessment period. The population of African savanna elephants dropped by at least 60% over the last 50 years, according to the IUCN, which tracks the assessment risk of the world's animals. Africa currently has an estimated 415,000 elephants, counting the two species together.Both elephant species experienced significant population decreases because of poaching. Although it peaked in 2011, illegal hunting still happens and continues to threaten elephant populations. African elephants also face continued habitat loss as their land isconvertedfor agriculture or other uses.There is some good conservation news, the IUCN points out. Anti-poaching measures, combined with better land use planning to support better human-wildlife relationships, have helped conservation efforts. Some forest elephant population figures have stabilized in well-managed areas in Gabon and the Republic of Congo and savanna population figures have remained stable or have been growing, particularly in the Kavango-Zambezi Transfrontier Conservation Area in southern Africa.But with constant demand for ivory and increasing human pressures on Africa's wild lands, concern for Africa's elephants is high, and the need to creatively conserve and wisely manage these animals and their habitats is more severe than ever.8. What can be inferred from the new report about African elephants?A. They are divided into three kinds.B. They are dying out.C. Their threat is mainly from poaching.D. Their population has grown in Africa.9. What does the author mainly tell us in Paragraph 3?A. The detailed number of African elephants.B. The similarities of African elephants.C. The different types of African elephants.D. The present situation of African elephants.10. What does the underlined word "converted" in Paragraph 4 probably mean?A. Expanded.B. Protected.C. Transformed.D. Forbidden.11. What's the authors attitude to the present situation of African elephants?A. Hopeless.B. Optimistic.C. Uncertain.D. Worried.DWhen a United Kingdomsupermarket chain promised to move its farms to Net Zero by 2030, it made it clear that the effort would require working on many different fronts. From energy consumption and land - use change to methane emissions (甲烷排放), cattle farming comes with environmental challenges. So even if recent studies suggesting it's possible to cut methane emissions 80% do turn out to be accurate, there's still a very long way togo for most cattle farming to get anywhere close to truly net zero.Organic Valley, when producing milk, might be closer to that goal. It made headlines in 2019 by going 100% renewable (可再生的). Now the company is expanding on that tradition by starting a major loan initiative (贷款计划) to help its farm suppliers adopt renewable energy too.Created with Clean Energy Credit Union, the $ 1 million loan fund will deliver loans at below - marketrates. Specifically, the money will be made available to Organic Valley's 1, 700 farmer members, and can be used for a variety of projects.“We are focused on a whole systems approach to renewable energy, and I'm excited to launch this energy loan fund. From the farm to the shelf, I see renewable energy playing a bigger role in organic food,” said Bob Kirchoff, Organic Valley CEO.“Organic Valley is already helping to protect the environment through organic farming practices, and now they re going one step further by supporting the introduction of renewable energy projects for their farmer members,” said Blake Jones, volunteer board chair of Clean Energy Credit Union. “In addition to the environmental benefits, we re eager to help family farmers throughout the world to lower their energy costs.”The world is not short of examples of farmers innovating in the field of renewable energy. What's encouraging about Organic Valley's announcement is the idea of a national brand putting its marketing and financing weight behind such efforts and, hopefully, creating consumer demand that pushes the rest of the industry in this direction too.12. What does paragraph 1 indicate about going net zero for cattle farming?A It is not easy to achieve B. It is common in the UKC. It is an impractical goalD. It meets no challenges13. What is Organic Valley's tradition according to the text?A. Helping farm suppliersB. Using renewable energyC. Having a loan initiativeD. Making headlines annually14. What is Organic Valley's initiative mainly intended to do?A. Reform organic farming practicesB. Make use of environmental benefitsC. Help farmers decrease energy costsD. Shrink the group of farmer members15. What is the author's attitude towards Organic Valley's initiative?A. WorriedB. DoubtfulC. AmbiguousD.
