2021届烟台市中英文学校高三英语下学期期末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ASan Francisco Bay Area is a great place if you're a sports fan as you'll find several events all year round and plenty of team pride. If you are anywhere close to the area during a game,these fantastic sports events are here for you.San Francisco Giants BaseballThe San Francisco Giants baseball team plays in SF at Oracle Park. This is a fun ballpark because it's always packed with great energy and offers views of the bay. It's one of the most popular San Francisco sports events. The Giants are part of the National League West Division. Since their arrival here in 1958,they have been World Series Champions three times.Golden State Warriors BasketballThe fan base of the Golden State Warriors distributes the whole San Francisco Bay Area as this region's only NBA team.Their regular season runs from late October through mid-April, and all home games are played at the Chase Center in San Francisco.In total, the Warriors has won six NBA championships.San Francisco 49ers FootballThe 49ers are San Francisco's NFL team, though they have recently moved to Levi's Stadium in Santa Clara, about an hour south of SF. The football team was named for the prospectors (探矿者) who arrived in the area in 1849 for the Gold Rush. They’ve won 5 Super Bowl championships, all between 1981 and 1994.San Jose Sharks HockeyThe San Jose Sharks represent the Bay Area in hockey (冰球).They were founded in 1991 as the only Bay Area team to compete in the NHL. Sharks fans love going to these San Francisco sports events at the SAP Center,which they call the Shark Tank,located about an hour southeast of SF.1.Where can a sports fan have a good view of the area?A.The Oracle Park.B.The Chase Center.C.Levi's Stadium.D.The SAP Center2.Which team has claimed the most titles according to the text?A.The Giants.B.The Golden State Warriors.C.The 49ers.D.The San Jose Sharks.3.Where is the passage probably taken from?A.A book review.B.A news report.C.A science fiction.D.A tourist magazine.BThis year researchers expect the world to snap 1.35 trillion photographs, or about 3.7 billion per day. All those pixels (像素) take up a lot of room if they are stored on personal computers or s phones, which is one reason why many people store their images in the cloud. But unlike a hard on drive which can be encrypted to protect its data, cloud storage users have to trust that a tech platform will keep their private pictures safe. Now a team of Columbia University computer scientists has developed a tool to encrypt (加密) images stored on many popular cloud services while allowing authorized users to browse and display their photographs as usual.Malicious (恶意的) attempts to access or leak cloud-based photographs can expose personal information. In November 2019, for example, a bug in the popular photograph storage app Google Photos mistakenly shared some users' private videos with strangers. Security experts also worry about employees at cloud storage companies on purpose accessing users' images.So the Columbia researchers came up with a system called Easy Secure Photos (ESP), which they presented at a recent conference. “We wanted to see if we could make it possible to encrypt data while using existing services,” says computer scientist Jason Nieh, one of the developers of ESP. “Everyone wants to stay with Google Photos and not have to register on a new encrypted-image cloud storage service.”To overcome this problem, they created a tool that preserves blocks of pixels but moves them around to effectively hide the photograph. First, ESP's algorithm (算法) divides a photograph into three separate files, each one containing the image's red, green or blue color1 data. Then the system hides the pixel blocks around among these three files (allowing a block from the red file, for instance, to hide out in the green or blue ones). But the program does nothing within the pixel blocks, where all the image processing happens. As a result, the files remain unchanged images but end up looking like grainy black-and-white ones to anyone who accesses them without the decryption (解密) key.4. What's probably the main purpose for people to store images in the cloud?A. To save storage room.B. To make photos beautiful.C. To try a new storage way.D. To keep their privacy safe.5. Why might employees in cloud storage companies be distrusted by experts?A. They sell users' passwords.B. They have invented new tools.C. They often let out personal information.D. They may steal a glance at users' images.6. What's the advantage of ESP?A. It can provide clear images.B. It can decrease the upload time.C. It can classify images automatically.D. It can encrypt data on the original platform.7. What does paragraph 4 mainly talk about?A. Method of decryption.B. Image-processing technique.C. Separate files of images.D. Data analysisof color1 s.CConcrete is the world's most consumed material after water. Because it already surrounds us in the built environment, researchers have been exploring the idea of using concrete to store electricity—turning buildings into giant batteries. The idea has been gaining ground as we have come to increasingly rely on renewable energy from the wind and sun: rechargeable batteries are necessary when the breeze dies down or darkness falls.Experimental concrete batteries have only managed to hold a small part of what a traditional battery does. But one team now reports in Buildings that it has developed a rechargeable original model that could represent a more than 900 percent increase in stored charge, compared with earlier attempts.A live-in concrete battery might sound unlikely. Still, "you can make a battery out of a potato," notes Aimee Byrne. In a future where sustainability is key, she likes the idea of buildings that avoid waste by providing shelter and powering electronics.Although the new design stores more than 10 times as much power as earlier attempts, it still has a long way to go: 200 square meters of it "can provide about 8 percent of the daily electricity consumption" of a typical U.S. home, Zhang says.This is not enough to compete with today's rechargeable devices. "We're getting milliamps (毫安) out of concrete batteries—we're not getting amps (安培), "Byrne says." We're getting hours as opposed to days of charge." But she adds that" concrete batteries are completely in their childhood, compared to other battery designs." The earliest batteries were simple andbulky. Researchers experimented with new materials and designsfor more than a century to develop today's small devices. Byrne suggests concrete-based energy storage could undergo a similar evolution. "The whole idea is that we're looking far into the future," she says. "We're playing the long game with it."8. What can we learn about the concrete batteries?A. They become increasingly renewable.B. They are the most consumed batteries.C. They are being developed by researchers.D. They will replace energy from the wind and sun.9. Why does Byrne mention a battery out of a potato?A. To show it is easy to build concrete batteries.B. To argue it is possible to develop concrete batteries.C. To make her statement more interesting.D. To call on people to protect the environment.10. What does the underlined word "bulky" in Paragraph 5 mean?A. HeavyB. CheapC. EfficientD. Small.11. What doesByrne think of concrete batteries?A. They beat today's rechargeable devices.B. They are simple and bulky.C. They have a doubtful future.D. They have a long way to go.DIn many countries of the world, people can confidently tell youthe meaning of their town or city, but most people who live inManchester,OxfordorBirminghamwould not be able to explain what the name of their city means. The name of every British town and city, however, has a long history.Two thousand years ago, most people living inBritainwere Celts. Even the word “Britain" is Celtic (凯尔特语).Then the Romans arrived and built camps which became cities called “castra". This is why there are so many place names inEnglandwhich end in "-chester" or “-caster"Manchester, for example.The Romans never reachedWalesorScotland, and many placenames there are Celtic. For example,Welsh place names that begin with “Llan" come from the Celtic word for "church".After the Romans leftBritain, it was attacked by the Anglo-Saxons who were from the area of Europe that is nowGermanyandHolland. The names of their villages often ended in “-ham" or “-ton". Some got their names from the leader of the village.SoBirminghamfor example, means "Beormund's village”The Anglo-Saxons were farmers and the landscape was very important to them, so we have villages called Upton (village on a hill)——a good place to build a village and Moreton (“village by a lake”)where floods could make life hard. Place names that end in “-ford" (a place where you could cross a river) also describe the location ofAnglo-Saxon villages.Finally, in 1066EnglandbecameNorman—theNormansgave us the place name "grange", which means farm.And how aboutLondon? Experts cannot agree. The Romans called the city Londinium, but they were not the first inhabitants (居民). People once believed that theUnited Kingdom’s capital city got its name from the castle of a King called Lud but this is very unlikely. Our best guess today is that the name comes from a Celtic word meaning a fast-flowing river. Like a number of British place names, its history is lost in time.12. The origin of British place names is unfamiliar to many local people because ofA. the death of local languagesB. the long lost history of the namesC. their lack of interest in itD. the frequent changes to the names13. According to the article,Stratfordis most likely a town .A. on a hillB. near a castleC. beside a riverD. with a church14. Which of the following shows the correct order of the arrival of inhabitants inBritain?A. The Celts—The Romans—TheNormans—The Anglo SaxonsB. The Celts—The Romans—The Anglo Saxons—TheNormansC. The Romans—The Celts—The Anglo Saxons—TheNormansD. The Romans―The Anglo Saxons—The Celts—TheNormans15. What doesLondonmean in Celtic?A. RiverB. LondiniumC. LudD. Castle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。

2021届烟台市中英文学校高三英语下学期期末考试试题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ASevenhugs HugOneDo you want to improve the quality of your sleep? Sevenhugs has created HugOne that tracks different sleep patterns to help families consistently rest better. There are dozens of devices and tools devoted to monitoring the sleep. But, HugOne is the world’s first family smart home sleep system, which integrates a calculation rule for sleep patterns of children and adults.HugOne is a well-designed product, full of a sense of science and technology. It connects to a number of smaller sensors called “minihugs”, which are placed on the edge of each bed. They monitor the sleep patterns and other data coming from the person sleeping in that bed. The data arethen sent to an app on the smartphone.● The benefits of HugOne include:* Having a smart alarm clock on the app as HugOne learns your sleep cycle and automatically sets and sounds to when the best moment in your sleep cycle is identified.* Monitoring temperature and humidity in your bedroom as well as indoor air quality for the main living space.* Linking with smart lamps and thermostats, allowing users to fall asleep with sunset light and preferred nighttime temperatures, and wake up to sunrise light and preferred daytime temperatures.* Ensuring safety from electronic transmissions when you sleep-when the minihug senses a presence in bed, it shuts off its electronic transmissions and starts recording sleep data and sending them to the app.● The following are selected from customers’ comments:I prefer HugOne, since it’s convenient to use. I simply place the minihug in the corner of my bed under the sheet and it goes to work monitoring my sleep cycle. It’s really good.—Robert Compton● HugOne available for purchase includes:I think HugOne is a humanized product. It’s shareable, and I’ve connected eight minihugs to the HugOne base in my house. All my family members think highly of it.—Chris HanawaltHugOne will provide maximum protection for your sleep. If you want to get more detailed information, please call the sellers at 1-800-576-1899 or .Style: Sleep Tracking System＋2 Sleep SensorsColour: Blue＋Rose1. How does HugOne effectively work?A. It controls sleep patterns automatically.B. It creates smart systems for a better sleep.C. It collects sleep data through the minihugs.D. It makes a calculation of the data sensors need.2. According to the passage, HugOne can ______.A. adjust temperature, humidity and air quality in bedroomsB. update the sleep cycles by aid of an alarm clock on the appC. record sleep data when there are electronic transmissions in bedD. help users fall asleep and wake up naturally with preferred temperatures3. The passage is made more believable by ______.A. providing statisticsB. drawing a comparisonC. giving a demonstrationD. using recommendationsBThere are three of us in the laboratory: Jules, me and Dr. Leonards. Leonards asks me to sit in front of Jules. As I do, he looks me in the eye and starts to move his face through a series of emotions-happy, confused, surprised, glaring. I'm attracted by his display, feeling delight when hegrinsand feeling serious when his eyes narrow angrily. None of this would be a surprise, of course, if Jules were a human. But he's a robot head on a table.The most special thing is that, consciously(有意识地), there's no mistaking Jules for a real person. Although he has surprisingly realistic skin, his eyes don't fit firmly against his lids, and he has a terrible hairpiece. Yet, as I walk into the room, I experience a complex worry of feeling in his direction. It's not at all like entering an empty space. It's a bit awkward for Jules’ shining false hair. Some unconscious part of me is responding to him as if he's real. This matters, because if we're to one day live comfortably along with robots , an understanding of how we instinctively(本能地) react to them is significant. The study of these issues is the frontier of a new scientific research; human-robot interaction.Jules was built as part of an attempt to understand the emotions that can be communicated by a human. “Allthe robots we'vebuilt so far don't have that rich emotions. We wanted to build a robotic face, with small motors that mimic(模仿) all the muscles you have, so we could discover what it could express. "Such research is becoming increasingly important, says Dr. Leonards, partly because our rapidly ageing population will soon need the help of robots with which they can effortlessly interact.4. What does the author think of Jules?A. He ignored him in his place.B. He didn't treat him as only a robot.C. He was afraid of his being there.D. He mistook him for a real person.5. What is the purpose to build such a robot?A. To help humans of old ages.B. To carry out a scientific research.C. To take the place of human labour.D. To make an interaction with human.6. What doesthe underlined word “grins” mean in Paragraph1?A. Smiles.B. Shakes.C. Worries.D. Cries.7. What may be the best title for the text?A. Human And RobotB. Success Of Making A RobotC. Robot Will Replace ManD. Difference Between Man And RobotCHow 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 valuerecycling 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．DA young female athlete in thePhilippinesrecently won many gold medals during a sports meet despite not having proper running shoes. Rhea Ballos, an 11-year-old student ofSalvationElementary Schoolin Balason,Iloilo, wasonly wearing bandages around her feet when she competed at the Iloilo Schools Sports Meet.Facebook user Valenzuela posted pictures of the girl with her feet wrapped in bandages bearing the famous Nike logo. Ballos even wrote the word “NIKE” on the sides of her “shoe” to complete the “Nike running shoes” look. The bandages were tightly wrapped around her feet, creating a thin protective layer against the track. While she was actually barefoot during the races, she was still able to defeat her competitors who all more proper footwear intended for running,According to the post, Ballos bagged the top awards in the 400-meter dash, the 800-meter run, and the1500-meter run in the girls' categories in the inter school sporting event held in Iloilo, central Philippines.When pictures of her “Nike” footwear become popular, Flipinos on social media praised her. Many noted that instead of falling into self-pity, she was even able to make light of the situation by drawing the Nike logo on her “running shoes”. Some of the commenters of Valenzuela's post expressed how the girl deserved to be recognized by Nike and that the brand should actually give her a new pair of real Nike shoes. Others started getting in touch with the American sports brand, as well as local basketball specialty store Titan 22.It did not take long for Titan co-founder and Alaska Aces head coach Jeffrey Cariaso to take notice of Ballos' outstanding achievement. Cariaso immediately made an effort to get in touch with the young track runner. The seven-time PBA champion has since talked to the student as well as her coaches in an apparent bid to help her out.12. Why did Ballos wear bandages around her feet to compete?A. She couldn't afford to buy shoes.B. She wished to be noticed by Nike.C. She wanted to draw public's attention.D. She thought it fashionable and unique.13. What's people's attitude to Ballos' story?A. Surprised.B. Confused.C. Favorable.D. Doubtful.14. What can we infer from the last paragraph?A. Ballos will be recognized by Nike.B. Ballos will be probably helped by Cariaso.C. Ballos is bound to win more champions.D. Ballos will become a great basketball player.15. Which of the following can best describe Ballos?A. Shy and lucky.B. Kind and brave.C. Clever and outstanding.D. Gifted and optimistic.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。

2021届烟台市中英文学校高三英语上学期期末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AWhen the sun shines brightly, it provides a great chance to get outdoor things done. Like making hay! At least, that is what farmers from the past would say. ―Make hay while the sun shines.This idiom is very old, dating back to Medieval times. Rain would often ruin the process of making hay. So, farmers had no choice but to make hay when the sun was shining.Today, we all use this expression, not just farmers. When conditions are perfect to get something done, we can say, ―It’s a good idea to make hay while the sun shines.In other words, you are taking advantage of a good situation or of good conditions. You are making the most of your opportunities. These all mean ―making hay while the sun shines.And sometimes we use this expression to mean we beat someone to the punch, or we got ahead of someone else. And other times you make hay while the sun shines to make good use of the chance to do something while it lasts. You are being opportunistic – taking advantage of a good opportunity. For example, my friend Ozzy was sick for a week and could not go to work. So, his co-worker Sarah -- who doesn’t like him -- took advantage of his illness and stole his project! Talk about making hay while the sun shines.Sometimes when you make hay while the sun shines you are staying ahead of a problem – like in this example:Hey, do you want to go hiking with me and my friends this weekend? The weather is going to be beautiful! I wish I could. But I have to finish my taxes. It’s the last weekend before they’re due.Oh, that’s too bad.Wait. What about your taxes?My taxes are done. I was off from work a couple of weeks ago and made hay while the sun shined. I got all of it done!I wish I would have taken advantage of my time off last week___1___All I did was lay around thehouse.And that’s all the time we have for these Words and Their Stories. But join us again next week. You can listen while you’re making dinner or riding to work. Yeah, make hay while the sun shines.1.Which of the following best matches ―make hay whilethe sun shines in paragraph 2?A.Sow nothing, reap nothing.B.Sharp tools make good work.C.Strike while the iron is hot.D.One swallow doesn’t make a summer.2.According to the underlined sentence, what feeling does the speaker express?A.AdmirableB.RegretfulC.AnnoyedD.Indifferent3.Where is the passage probably taken from?A.A radio programB.A magazineC.A brochureD.A novelBTofight for the conservation of forest ecosystem, several ecologists including Daniel Janzen convinced Del Oro, an orange juice producer, to donate part of their forestland to a national park. In return, Del Oro was allowed to throw large amounts of waste in the form of orangepeels(皮) on a 3-hectare piece of land within the national park at no cost. Dealing with tons of leftover peels usually involved burning them or paying to have them poured into a landfill, so the proposal was very attractive.But a year later, another juice company challenged the deal in court, arguing that their competitor was "polluting a national park". They ended up winning, and the deal between Del Oro and the national park fell through.Then in 2013, while discussing possible research avenues（途径，手段）with Timothy Treuer, Daniel Janzen mentioned the orange story. Feeling interested, Treuer decided to stop by that piece of land that had been covered with fruit waste 15 years earlier. What he found shocked him."While I would walk over exposed rock and dead grass in the nearby fields, I'd have to climb through undergrowth and cut paths through walls ofvines(藤) in the orange peel site itself," said Timothy Treuer.Treuer and his team spent months picking upsamples(样品), analyzing and comparing them. They found great differences between the areas covered with orange peels and those that were not. The area withorange waste had richer soil.The effect that the orange peels had on the land is probably not that surprising to people familiar withcomposting(施肥), but what is really shocking is that a judge actually thought the waste of orange "mined" a national parkand stopped it from going forward. Now that Timothy Treuer's study has received worldwide attention, this type of "ruining" is being seriously considered as a way of bringing forests back to life.4. What did Del Oro usually do with orange peels?A. Add them to fuel.B. Feed them to animals.C. Burn or bury them.D. Make them into cakes.5. What can we know about the deal between Del Oro and the national park?A. It lasted 15 years.B. It was signed by Treuer.C. It was made in about 1998.D. It was broken by Del Oro.6. What was Treuer's finding?A. Orange peels contain much fibre.B. Orange peels can make soil richer.C. Orange peels rot away in a short time.D. Orange waste ruined the national park.7. What is the author's attitude toward the judge mentioned in the last paragraph?A. Disapproving.B. Positive.C. Worried.D. Admirable.CWhen I was trying to find a place where to spend my December holidays, I met by chance some cheap flights to Iceland. After checking just a few winter pictures of Iceland, I realized that the country, known as the land of fire and ice, during the cold months of the year could offer me experiences I had never had before.For sure you can’t miss the chance to go to Iceland in winter if your traveling wish list includes at least one of the crazy experiences Iceland can offer. Iceland in the North Atlantic Ocean is a paradise (乐园) for all those who want to see the northern lights, experience cold weather conditions and put themselves in geothermal (地热的) baths while the snow is falling on their head.The best way to move around Iceland is with a rental car. Distances are huge and public transport in winter is not really common out of the major towns. As we wanted to be even more convenient we decided to rent a small camper (野营车). Sleeping and cooking in a camper saved us a lot of driving, money and gave us the chance tobe always in the right place at the right time.There were also no locals and in many cases no tourist facilities (设备). For us, as we slept in a camper, it was easier. But for tourists traveling by normal cars it is necessary to check the opening times ofhotels and restaurants as many of them run just from June to September.It is amazing to experience how the weather is changing in Iceland. However, Icelanders prefer to stay inside their houses. They have even no time to complain about the weather in December. All they care about is Christmas. They love to decorate their houses, sing Christmas songs and eat typical Christmas food.8. Why is Iceland famous as the land of fire and ice?A. Because tourists would like to play with fire on the ice.B. Because it is too dry to easily cause fire to happen.C. Because it is hot inside a house and cold outside.D. Because there exist hot springs and freezing ice.9. What did the author think of the rented camper?A. It was not only practical but also economical.B. It was convenient but cost them more money.C. It provided the best chance to see the new country.D. It was much faster than other public transport.10. What does the last paragraph imply?A. The Icelanders prefer to live with their family.B. The joy of Christmas drives the freezing weather away.C. December is the coldest month of the year.D. The Icelanders are always positive and stay outside.11. What does this passage most probably come from?A. A textbookB. A scientific reportC. A travel magazineD. A news reportDJapan is known to have higher than average rates of stomach cancer. Recently, the town of Kaneyama in Yamagata Prefecture decided to get its 6, 000 residents (居民) tested.However, the frozen urine samples (尿样) are not tested in conventional ways. Instead, Professor Masao Miyashita and his team are using them in a trial to determine if specially trained cancer-sniffing dogs can accurately detect the disease. Though the study is still in its early stages, Miyashita is thrilled with the results. He said, “In our research so far, cancer detection dogs have been able to find signs of cancer with an accuracy of nearly 100 percent.”Researchers have known about the animals’ superior sensory skills for decades. However, their ability to detect cancer in humans came to light in 1989, after a dog sniffed out early-stage malignant melanoma (恶性黑色素瘤) on a patient’s leg in London. Since then, scientists from many countries have conducted studies to test dogs’ great skill at identifying cancer chemicals.While most dogs can be trained for the task researchers say the best candidates are dogs that are precise, quiet, and perhaps even a little shy. The training process is similar to how dogs are taught to learn any trick — byrewarding them with treats! However, it takes much longer because the dogs have to learn to separate the “cancer scent (气味)”from the thousands of organic compounds (有机化合物) in the human body. Researchers begin by exposing the dogs to urine samples from people with cancer, people with other diseases, and patients with no health issues, Once the dogs are able to accurately identify cancer, they are further trained to detect particular kinds of cancer.Successful as they may be, experts think dogs are unlikely to replace conventional tests. For one, it takes about seven years and costs as much as $45,000 to train a single dog. Klaus Hackner, a researcher and physician who studies dogs detecting cancer in breath samples at Krems University Hospital in Austria, is also not convinced dogs can be relied upon alone. Patients, therefore, have to receive further tests to confirm if they have the disease.12. What do we know about the cancer-sniffing dogs mentioned in Paragraph 2?A. They have done a great job.B. They are trained in a special way.C. They can easily learn to distinguish cancer.D. They can be seen in many Japanese hospitals.13. What does the author intend to do in Paragraph 3?A. Offer readers some advice.B. Add some background information.C. Summarize the previous paragraphs.D. Introduce a new topic for discussion.14. What kind of dog is suitable for the cancer-sniffing job?A. Smart and brave.B. Active and faithful.C. Strong and patient.D. Careful and peaceful.15. What is Klaus Hackner’s opinion on cancer-sniffing dogs?A. They should work as a team.B. They need to receive more training.C. They can replace doctors in detecting cancer.D. They should be used together with traditional tests.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。

2021届烟台市双语实验学校高三英语期末考试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.BAt the World Economic Forum last month, President Trump drew claps when he announced the United States would respond to the forum's proposal to plant one trillion(万亿) trees to fight climate change. The trillion-tree idea won wide attention last summer after a study published in the journal Science concluded thatplanting so many trees was “the most effective climate change solution to date”.If only it were true. But it isn't. Planting trees would slow down the planet's warming, but the only thing that will save us and future generations from paying a huge price in dollars, lives and damage to nature is rapid and considerable reductions in carbon release from fossil fuels, to net zero by 2050.Focusing on trees as the big solution to climate change is a dangerous diversion(偏离). Worse still, it takes attention away from those responsible for the carbon release that are pushing us toward disaster. For example, in the Netherlands, you can pay Shell an additional 1 euro cent for each liter of regular gasoline you put in your tank, to plant trees to balance the carbon release from your driving. That's clearly no more than disaster slightly delayed. The only way to stop this planet from overheating is through political, economic, technological and social solutions that end the use of fossil fuels.There is no way that planting trees, even across a global area the size of theUnited States, can absorb the huge amounts of fossil carbon released from industrial societies. Trees do take up carbon from the atmosphere as they grow. But this uptake merely replaces carbon lost when forests were cleared in the first place, usually long ago. Regrowing forests where they once grew can undo some damage done in the past, but even a trillion trees can't store enough carbon to head off dramatic climate changes this century.In a sharp counter argument to last summer's Paper in Science, Justin Gillis wrote in the same journal in October that the study's findings were inconsistent with the dynamics of the global carbon cycle. He warned that “the claimthat global tree restoration(复原) is our most effective climate solution is simply scientifically incorrect and dangerously misleading”.4. What do we know about the trillion-tree idea?A. It was published in a journal.B. It was proposed last summer.C. It was put forward by Trump.D. It drew lots of public attention.5. What is paragraph 3 mainly about?A. A drawback of the tree planting strategy.B. An example of balancing carbon release.C. An anecdote of making a purchase at Shell.D. A responsibility for politicians and economists.6. What was Justin Gillis's attitude towards global tree restoration?A. Indifferent.B. Opposed.C. Hesitant.D. Supportive.7. What is the best title for the text?A. Contradictory Ideas on Tree Planting.B. A Trillion Trees Come to the Rescue.C. Planting Trees Won't Save the World.D. The Best Solution to Climate Change.CA North Atlantic right whale calf(幼崽) was discovered dead on the beach of an island off North Carolina. The male newborn was found on North Core Banks, part of the Cape Lookout National Seashore. The reports indicate that the animal died during birth or shortly after, according to the National Oceanic and Atmospheric Administration(NOAA). Scientists took DNA to determine the calf’s mother.This is the beginning of the right whale’s reproduction(繁殖) season, which begins mid-November and runs through mid-April. NOAA called this death a disastrous start to the season. Each new right whale calf brings so much hope for this badly endangered animals, and losses like this have a great impact on their recovery, NOAAsaid.The right whale is one of the rarest marine mammals(哺乳动物) in the world, according to NOAA. They will soon be extinct unless something is done to save it, researchers warn. This kind of whale has been experiencing an Unusual Death Event over the past three years, according to NOAA. Since 2017, at least 32 dead and 13 seriously wounded whales have been documented by the organization. “This means more than 10 percent of the remaining population,” according to NOAA.NOAA posted a piece of news on Monday, the same day they announced the calf’s death, warning boaters to be watchful as the whales are migrating(迁徙) nearly 1,000 miles along the Atlantic Coast. The organization calls for boaters to be watchful, slow down and to give these endangered whales plenty of room. They also ask all fishermen to remove their unused nets from the ocean to help avoid possibledamage.8. Why did scientists take DNA of the calf?A. To save its mother.B. To confirm its identity.C. To determine the time of its death.D. To uncover the cause of its death.9. How many right whales are left according to the passage?A. About 40.B. About 50.C. About 400.D. About 500.10. What do we know aboutNorth Atlanticright whales?A. Their reproduction season usually last about half a year.B. They are the rarest marine mammals in the world.C. They are experiencing a high death rate of newborns.D. Their habitat runs nearly 1,000 miles along the coast.11. What’s the main purpose of the news posted on Monday?A. To announce the calf’s unusual death.B. To remind boaters to watch the whales.C. To protect the boats against the whales.D. To assist the whales’ seasonal migration.DWhen rescuers were called to rescue a “little owl”, they did not expect to find one that was too fat to fly. A concerned citizen first spotted the poor bird lying helplessly. Even Rufus Samkin, whose team then took the team in on Jan.3, believed the bird to be injured. There were no wounds to be found, however, causing experts tobelieve the female owl was simply too wet to fly.But it was only after a thorough drying-off and complete checkup that they noted the real issue. The rescuers weighed the owl and concluded that she was “simply extremely obese” and couldn’t take off. This additional weight left her unable to fly, though experts began to wonder how she got so fat in the first place. Because it’s rather unusual for wild birds to reach such a state, they decided to keep her a few weeks and monitor her.In the end, the rescuers assessed that it was simply a case of “natural obesity”. December 2019 was quite warm, which meant that there were many insects for the bird to feast upon. Indeed, the owl was discovered in a field that was “filled with field mice” due to the usual climate. “It’s been very mild here, and the owl is able to find foods easily,” Samkin explained. With the sudden food, “she ly ate much and got very fat. She had a lovely time, but went too far.”The researchers consequently put the owl on a “strict diet” so she could shrink to a more “natural weight”. She was even put on a bit of exercise and encouraged to fly around. In the end, the bird was sent flying gracefully off into the British countryside at a much healthier and happier weight. Hopefully, this owl won’t come upon another feast of field mice—unless she wants another few weeks at the fat camp.12. What did people think happened to the owl at first?A. She was hurt.B. She was trapped.C. She was hungry.D. She was wet.13. Why was the bird unable to fly?A. She needed a thorough checkup.B. She should be given a drying-off.C. She was completed overweight.D. She was simply extremely strong.14. What made the owl have enough foods?A. The especially warm weather.B. The reducing number of insects.C. The rich fields growing crops.D. The lovely time the bird enjoyed.15. How did the owl loseits weight?A. Going on a diet and exercising.B. Flying in the British countryside.C. Visiting that fat camp again.D. Enjoying her wonderful feast freely.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。

2021年烟台市中英文学校高三英语下学期期末考试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ALocated inLos Angeles,UniversityofSouthern Californiais in the heart of a leading city. Although LA ranks highly in The Economist’s Safe Cities Index, navigating and city calls for certain safety precautions (预防措施) along with practicing common sense.♦Mobile Safety App Powered by LiveSafeThe Mobile Safety App powered by LiveSafe, manage by the USC Department of Public Safety and the USC Department of Emergency Planning, is a free downloadable app that mobile users can use to initiate contact with emergency responders around the campus. Features include: immediate “push button” calls to DPS, easy reporting for suspicious activity or crimes in progress, and location services to notify friends of your route through campus.♦Blue Light Phone LocationsTheUniversity Parkhas multiple blue light phones that are strategically placed throughout campus. Take note of where the closest ones are on your route. They come in handy in case you lose your phone or in an emergency. These phones are directly connected to USC’s Department of Public Safety’s 24-hour communications center. Besides emergency needs, it can also be used to report suspicious activity, request for an escort (护送) if you feel unsafe and to report a crime.♦Trojans AlertTrojans Alert is an emergency notification system that allows university officials to contact you during an emergency by sending messages via text message or email. When an emergency occurs, authorized USC senders will instantly notify you with real-time updates, instructions on where to go, what to do (or what not to do), whom to contact and other important information.

Children’s toys that rely on robotics for both entertainment and education are becoming more popular and more easily accessible. Robot vacuums, too, are so popular that the Roomba has even earned itself a name in popular television.A selection of other household wares can be purchased and owned for a reasonable cost, but they all look and perform like vacuums. Our domestic helpers are currently designed to vacuuming, mopping, sweeping and mowing.Of course the best known of these is the Roomba, but there is actually some competition amongst the autonomous vacuum manufacturers. Roomba, made by iRobot, now comes in several designs and has been through many versions of improvements. The basic model is just about $400, but there’s a more attractive version, complete with a wireless command center to control the robot from anywhere in the home. Samsung also has a vacuum, called the Smart Tango, which makes increased improvements on the Roomba by including brushes for cleaning corners. It’s possible that some of the less well-known vacuums might be even more exciting, like the Neato Robotics XV that takes on a square shape to better clean corners. Incremental (增值的) improvements are what drive the home robot industry.Now that domestic robots are becoming more popular, the near future should be exciting. If we are going to welcome robots into our lives and our homes, we should expect them to work for it, and work hard. It’s the dawn of the robot revolution, whether we like it or not, and it would be great to see that technology put to use in moreinnovative(创新的) ways.4. What does Roomba in the passage mean?A. A man’s name who has bought a domestic robot.B. A name of a big company who makes robots.C. A type of vacuum whose name is Roomba.D. A place where people can buy proper robots.5. The Smart Tango is different from other types in that ________.A. it has a wireless command centerB. it has brushes for cleaning cornersC. it is more famous and excitingD. it is driven without electricity6. What can we infer according to the last paragraph?A. Domestic robots will free us from housework.B. Domestic robots will become cheaper and cheaper.C. Domestic robots have brought environmental revolution.D. Domestic robots takes the lead in science and technology.7. What does the author intend to tell in the passage?A. Domestic robots are closely related to our daily life.B. It is interesting to see domestic robots at home.C. Domestic robots are too expensive for most people.D. It is convenient to buy a domestic robot.CFor years video games have been criticised for making people more antisocial, overweight or depressed. Bui now researchers are finding that video games can actually change us for the better and improve both our body and mind.Games can help to develop physical skills. Pre-school children who played interactive games have been shown to have improved motor skills, for example they can kick, catch and throw a ball better than children who don’t play video games. A study found that those who played video games were 27 percent faster and made 37 percent fewer errors than those who didn't.Games also benefit a variety of brain functions, including decision-making. People who play action-based games make decisions 25 percent faster than others, according to one study. It was also found that the best gamers can make choices and act on them up to six times a second, four times faster than most people. In another study by researchers from the University of Rochester in New York, experienced gamers were shown to be able topay attention to more than six things at once without getting confused, compared with the four that most people can normally keep in mind.There is also evidence that gaming can help with psychological problems. At the University of Auckland in New Zealand, researchers asked 94 young people diagnosed with depression to play a 3D fantasy game called SPARX and in many cases, the game reduced symptoms of depression more than conventional treatment.8. In what way playing video games benefits very young children?A. Muscle control.B. Social interaction.C. Decision-making.D. The ability to focus.9. Which type of video game improves the decision-making speed?A. Interactive games.B. Action-based games.C. 3D fantasy games.D. Violent games.10. What is the authors attitude to video games?A. Indifferent.B. Objective.C. Worried.D. Critical.11. What is the text mainly about?A. The effects of different types of video games.B. The negative effects of playing video games.C. The beneficial effects of playing video games.D. The effects of games on people's behavior.D“One person’s trash is another person’s treasure.” That’s a common expression, but the next time you throw something away, think about a twist on the old saying. What if your trash could become your own treasure? Many creative, thrifty, and environmentally minded people have come up with a way to makethathappen. It’s called upcycling. Our world would be a better place if everyone would begin upcycling.Upcycling is the practice of taking an unwanted item and turning it into something useful. For example, how about that pair of jeans with a hole in one knee? It could become a new pillow for your bedroom.Upcycling is not the same as recycling. Upcycling is actually much better for the environment. Recycling takes an item made of glass, paper, metal, or plastic, breaks it down to its base material, and then uses that material to make another product. This requires a great deal of energy. On the other hand, when you choose to upcycle, the only energy you use is your own. And upcycling not only reduces the amount of trash that goes into our landfills, but it also protects natural resources, such as oil and gas. Recycling is good for the environment, but upcycling is even better.Upcycling also makes a family’s budget stretch further. Of course, the idea of reusing items to save money isnot new. During the Great Depression in the 1930s, many families lived on a tight budget. People had to use what they already had in order to meet their needs.As responsible citizens, we should all be concerned with protecting our environment and budgeting our resources. Upcycling is a fun and creative way to help. The next time you go to toss something into the trash can, stop and think about what it could become. Chances are, there’s a brand-new item in your hand just waiting to be upcycled.12. Why does the author mention an old saying in the first paragraph?A. To arise reader’s awareness of upcycling.B. To stress the importance of upcycling.C. To lead in the topic of upcycling.D. To show the idea of upcycling.13. Which one below belongs to upcycling?A. An old ladder is transformed into a bookshelf.B. Old tin cans are transported to landfill.C. A broken wooden door is chopped up.D. Old cloth is made into a paper bed.14. What is the difference between recycling and upcycling?A. Upcycling is much more creative.B. Recycling is much easier to achieve.C. Recycling is much more cost-saving.D. Upcycling is much more energy-efficient.15. What can be inferred from the text?A. Upcycling is popular at present.B. Upcycling is replacing recycling.C. Upcycling is worth recommending.D. Upcycling is a tradition in daily life.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。

After all, she’s already got her master’s degree.The North Chicago-area teen started homeschooling at the age of 4. She began having an influence on others soon after. When she was 6 years old, she was an inspirational speaker at an organization called Tabitha House Community Service, which is for people who were forced to leave their homes because of earthquake, flood and other natural disasters.At the age of 11, she graduated from high school and then earned her bachelor’s degree in psychology in 2013. She completed those classes online as she was traveling for church events and leadership meetings.She doesn’t stop there, though. The teen plans to focus on aviation psychology (航空心理学) for her further study, a decision inspired by her father who is a pilot. She grew up around airplanes and took fights all the time. Her goal is to use it to help pilots deal with problems that could have deadly results once the plane takes off — a topic that has been in the news lately. For her, it’s a mix of two of her interests.In her free time, Thessalonika enjoys playing tennis, swimming and being active in her youth group at church.

Scott Kelly said he tried to express that view everywhere he went. And he spoke from experience, having spent a career that included the time as a NASA astronaut, US Navy captain, fighter pilot, and engineer.Scott spoke at the University of North Alabama, sharing stories about his experience of spending a year on the International Space Station (ISS). He said the physical pressure of living in weightlessness for a year was hard to describe and that the fluids(积水) in his head sometimes made him feel like he was standing on his head. It also needed some time to recover when he returned home. “My legs were weak and it would be uncomfortable to sit for a while because my body hadn’t had that pressure so long,” Scott said.He discussed life aboard including spending time with Russian astronauts. They came from different cultures. He had managed to get along well with everyone aboard as they lived together, worked together, and had to rely on each other. He thought it was one of the most rewarding things in his life.Though life there was not easy, Scott never regretted being an astronaut and going to space. He also discussed experiences growing up, admitting that he wasn’t always the greatest student but was able to overcome that through hard work and determination.“Never give up or lower your dreams. If you work for it, all things are possible. There is a zero percent chance of succeeding if you don’t even try. And when you succeed after trying hard, you’ll find it really rewarding,” Scott said in the end.8. Scott mentioned his experience in the ISS mainly to show ________.A. he enjoyed making speechesB. he was a responsible astronautC. his life in space was challengingD. the daily life of an astronaut can be boring9. What may benefit Scott most when he lived with Russian astronauts?A. He won some awards through teamwork.B. He found the fun of living in the Space Station.C. He learned to develop close relationships with others.D. He picked up some knowledge of Russian culture.10. Which of the following can best describe Scott?A. Kind and thoughtful.B. Curious and humorous.C. Easygoing and sociable.D. Hardworking and determined.11. What does the author intend to tell us from Scott’s story?A. It’s importantto have a dreamB. Easy things are also worth doingC. A suitable career leads one to success.D. Difficult things are demanding but rewardingDHappiness is not a warm phone, according to a new study exploring the link between young life satisfaction and screen time. The study was led by professor of psychology Jean M. Twenge at San Diego State University (SDSU).To research this link, Twenge, along with colleagues Gabrielle Martin at SDSU and W. Keith Campbell at the University of Georgia, dealt with data from the Monitoring the Future (MtF) study, a nationally representative survey of more than a million U. S. 8th-, 10th-, and 12th-graders. The survey asked students questions about how often they spent time on their Phones, tablets and computers, as well as questions about their face-to-face social interactions and their overall happiness.On average found that teens who spent more time in front of screen devices — playing computer games,using social media, texting and video chatting — were less happy than those who invested more time in non-screen activities like sports, reading newspapers and magazines, and face-to-face social interactions."The key to digital media use and happiness is limited use," Twenge said. "Aim to spend no more than two hours a day on digital media, and try to increase the amount of time you spend seeing friends face-to-face and exercising — two activities reliably linked to greater happiness."Looking at historical trends from the same age groups since the 1990s, it's easy to find that the increase of screen devices over time happened at the same time as a general drop-off in reported happiness inU. S.teens. Specifically, young peopled life satisfaction and happiness declined sharply after 2012. That's the year when the percentage of Americans who owned a smartphone rose above 50 percent. By far the largest change in teens' lives between 2012 and 2016 was the increase in the amount of time they spent on digital media, and the following decline in in-person social activities and sleep.12. Which method did Twenge's team use for the study?A. Calculating students' happiness.B. Asking students certain questions.C. Analyzing data from a survey.D. Doing experiments on screen time.13. How does the author develop the finding of the study in paragraph 3?A. By making a comparison.B. By giving an example.C. By making an argument.D. By introducing a concept.14. What is the purpose of the last paragraph?A To draw a conclusion from the study.B. To offer some advice to the readers.C. To prove social activities' importance.D. To support the researchers' finding.15. Which of the following can be the best title for the text?A. Quitting Phones Equals HappinessB. Screen Time Should Be BannedC. Teens' Lives Have Changed SharplyD. Screen-addicted Teens Are Unhappier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。

With the frequency of space launches dramatically increasing in recent years, the potential for a disastrous collision above Earth is continually growing. Now, Japanese orbital clean-up company Astroscale is testing a potential solution.The firm's End-of-Life Services by Astroscale demonstration mission is scheduled to lift off on 20 March aboard a Russian Soyuz rocket. It consists of two spacecraft: a smal “client” satellite and a larger “servicer” satellite, or “chaser”. The smaller satellite is equipped with a magnetic (磁力的) plate which allows the chaser todock withit.The two stacked spacecraft will perform three tests once in orbit, each of which will involve the servicer satellite releasing and then recapturing the client satellite. The first test will be the simplest, with the client satellite drifting a short distance away and then being recaptured. In the second test, the servicer satellite will set the client satellite tumbling before catching up with it and matching its motion to grab it.Finally, if those two tests go well, the chaser will live up to its name by letting the client satellite float a few hundred metres away before finding it and attaching to it. All of these tests will be performed autonomously, with little to no human input once they are set in motion.“These kinds of demonstrations have never been done before in space - they are very different to, say, anastronaut controlling a robotic arm on the International Space Station,” says Jason Forshaw at AstroscaleUK.“This is more of an autonomous mission.” At the end of the tests, both spacecraft will burn up in Earth's atmosphere.If companies wanted to use this capability, they would have to attach a magnetic plate to their satellites so they could be captured later. Because of the growing space garbage problem, many countries now require firms to have a way to bring back their satellites once they run out of fuel or fail, so this could be a fairly simple likely plan, Forshaw says. Right now, each chaser can only nab one satellite, but Astroscale is working on a version that could drag three or four out of orbit at once.4. Which of the following can replace the underlined word "dock with" in Paragraph 2?A. Deal with.B. Keep up with.C. Join together.D. Crash.5. Why many countries now require firms to have a way to bring back their satellites?A. Because of the growing space waste problem.B. Because the frequency of space launches are dramatically increasing.C. Because they can earn large profits from it.D. Because Astroscale has found a new method of capturing the space garbage.6. What will Astroscale do to solve the space junk problem?A. An astronaut controls a robotic arm on the International Space to capture the “client” satellite.B. Through a magnetic plate remotely controlled by humans on the ground to catch the “client” satellite.C. Finding the "client "satellite and attaching to it with a magnetic plate automatically.D. Tumbling to match the motion of “client satellite the drag three or four satellites out of its orbit into atmosphere.7. What can we infer from the passage?A. People will bum the space junk up in Earth's atmosphere in the future.B. Japan andRussiawill conduct space debris cleanup experiment together.C. These kinds of demonstrations have never been done before.D. The demonstration mission will be divided into three phases.CIn the summer of 2016, I gave a talk at a small conference in northernVirginia. I began by admitting that I’d never had a social-media account; I then outlined arguments for why other peopleshould consider removing social media from their lives. The event organizers uploaded the video of my talk to YouTube. Then it was sharedrepeatedly on Facebook and Instagram and, eventually, viewed more than five million times. I was both pleased and annoyed by the fact that my anti-social-media talk had found such a large audience on social media.I think of this event as typical of the love-hate relationships many of us have with Facebook, Instagram, and other social-media platforms. On the one hand, we’ve grown cautious about the so-called attention economy, which, in the name of corporate(公司的) profits, destroys social life gradually and offends privacy. But we also benefit from social media and hesitate to break away from it completely. Not long ago, Imet a partner at a large law firm in Washington, D.C., who told me that she keeps Instagram on her phone because she misses her kids when she travels; looking through pictures of them makes her feel better.In recent months, some of the biggest social-media companies, Facebook and Twitter, in particular, have promised various reforms. In March, Mark Zuckerberg announced a plan to move his platform toward private communication protected by end-to-end encryption(端对端加密); later that month, he put forward the establishment of a third-party group to set standards for acceptable content.All of these approaches assume that the reformation of social media will be a complex, lengthy, and gradual process. But not everyone sees it that way. Alongside these official responses, a loose collective of developers that calls itself the IndieWeb has been creating another alternative. They are developing their own social-media platforms, which they say will preserve what’s good about social media while getting rid of what’s bad. They hope to rebuild social media according to principles that are less corporate and more humane(人道的).8. Why did the author feel annoyed when his video was spread online?A. His video caused many arguments.B. His video was shared without his permission.C. His talk was opposed by a large amount of people.D. His video’s popularity on social media is against his talk.9. Why does the author mention the story of his partner in paragraph 2?A. To prove that social media has some benefits.B. To advise people to break away from social media.C. To tell the negative effects social media may produce.D. To describe people’s complicated relationships with social media.10. What is the purpose of the reform made by some social-media companies?A. To attract more users.B. To improve network environment.C. To make more profits.D. To provide more convenientservice.11. What does the IndieWeb intend to do?A. Develop new social-media platforms.B. Remove social media from people’s lives.C. Improve the existing social-media principles.D. Help social-media companies to make reformation.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.

2021届烟台市中英文学校高三英语上学期期末考试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AKate Humble: Books that changed my lifeKate Humble is a writer and broadcaster specializing in science, wildlife and rural affairs. Together with her husband site runs Humble by Nature, a rural skills education centre on working farm near Monmouth intheWyeValley.Winnie the Poohby A A MilneMy father used to read this to me when I was very young — he used different voices for all the animals. The characterization (角色设定) was so clever; we all know someone just like each inhabitant of the HundredAcre Wood: gloomy Eeyore; thick but loyal Pooh; enthusiastic Tigger.A A Milne was masterful in exploring the way they got along together, opening my eyes to how society really works.Last Chance to Seeby Douglas Adams and Mark CarwardineThis book tells of the authors, adventures as they set out to find the rarest of animals, those on the edge of extinction.Their travels are rather exciting and they share a wonderful humour, which really appealed to me. Yet underpinning (支撑) everything is the realization that we can't just sit back and allow species to disappear. PicturePalaceby Paul TherouxI've always loved Theroux's travel writing, but this novel took my breath away. The words aren't long or complicated but, fromthat first paragraph, his writing grabs you by the nose hairs and drags you along. I had an art teacher who told me, “You're only an artist when you've found your own style, not when you're copying someone else, and Theroux represents this.”1. Why did the author mention the characterization ofWinnie the Pooh?A. To indicate the book has realistic values.B. To show how adorable the characters are.C. To persuade people to learn from the characters.D. To prove the writer is good at creating characters.2. What didLast Chance to Seestrike into Kate's heart?A. Curiosity.B. Responsibility.C. Exploration.D. Devotion.3. Which writer does Kate Humble like for his original writing?A. A A Milne.B. Douglas Adams.C. Mark Carwardine.D. Paul Theroux.BIf you could travel back in time, which period of history would you visit? It’s a great question to ask your friends, and time travel is the subject of many science fiction films. Of course, sci-fi is familiar to most of us, butwhat is cli-fi? The simple answer is climate fiction which focuses on the subject of climate change.Many of the cli-fi examples we watch tend to be disaster films. It could be solar flares (太阳耀斑), ice ages devastating (摧毁) the planet, extreme flooding swamping the earth with water, or super-storms that threaten life as we know it. While films and novels of this style are often subject to the typical images of a hero or heroine battling to save the day, what sets it apart from most sci-fi films is that the plots will often draw on apparently reasonable outcomes in the near future.Climate change and the potential threats have long been established. Some believe that the issue of climate change has even led to more fans watching films to learn more about what's happening to the world – seeing it as a form of edutainment. A study conducted by the Yale programme on Climate Change Communication tested the effects that two climate fiction novels can have on its readers and found “significant positive effects” in terms of their attitudes and beliefs towards the climate crisis – for example, understanding global warming will harm them and future generations.Most climate films are not only extremely popular action films, but also cause our fear of what some see as the approaching end of the world. This sounds bad, but according to a study conducted on 310 adults in the US, watching such scary films can help us feel more prepared and less alone in situations such as the pandemic (疫情). So, it looks like cli-fi is hereto stay – and there seem to be some benefits. Whether it’s there to educate, entertain or prepare you for a climate crisis, it might have a role to play.4. Which of the following may be the subject of cli-fi?A. Time travel.B. Global warming.C. Weather forecast.D. Economic climate.5. What can we learn about cli-fi films from paragraph 2?A. They are often about extreme natural disasters.B. They want to show that man can conquer nature.C. They usually have similar plots with sci-fi films.D. They can show the true near future of the world.6. Why is the study conducted by the Yale programme mentioned in paragraph 3?A. To prove that climate change has potential threats.B. To show that people like climate fiction novels.C. To tell that cli-fi novels have positive effects on readers.D. To explain how the climate crisis affect the human being.7. What does the writer mainly want to tell us in the last paragraph?A. Cli-fi films are very popular as action films.B. A study was conducted on 310 adults in theUS.C. The pandemic make people scared and alone.D. Cli-fi films are useful and will be here to stay.CThe annual 3-to-4-millimeter rise in sea levels is expected to impact many coastal communities in the coming decades. However, few are as defenceless as the Republic of theMaldives, a collection of more than a thousand picturesque islands in theIndian Ocean. NASA researchers believe that parts of what is “arguably the lowest-lying country in the world” will become uninhabitable by 2050, due to wave-driven flooding and limited freshwater. To fight the unavoidable, the government recently revealed plans for the world's first 'true' floating island city.The aptly-named Maldives Floating City (MFC) is the brainchild of Dutch Docklands, a global leader in floating infrastructure (基建). According to the March 13, 2021, announcement, the new city will be constructed on a 200-hectare lagoon (环礁湖) located just 10 minutes by boat from the Maldivian capital, Male. It will initially consist of a thousand waterfront residences, arranged in a series of honeycomb-like maze rows. The developers plan to add hotels, restaurants, shops, and even a school and a hospital in the near future. The floating structures. will be attached to the surrounding islands, which will form a base and provide protection from high tides.Maldive officials aim to make MFC as self-sufficient as possible. Freshwater storage will provide drinkingwater for residents, while floating solar blankets and agriculture fields will take care of their energy and food needs.“ThisMaldivesFloatingCitydoes not require any land rehabilitation, therefore has a minimal impact on the coral reefs,” explains Mohamed Nasheed, Speaker of Parliament. “What's more, giant, new reefs will be grown to act as water breakers. In theMaldives,we cannot stop the waves, but we can rise with them.”Construction of the revolutionary city is expected to begin in 2022 and be completed in phases over the next five years. If successful, it will provide a blueprint for other countries facing a similar situation.8. Why doesMaldivesdecide to build MFC?A. It is the lowest-lying country.B. It will be flooded soon.C. It is running out of fresh water.D. It will be unsuitable for living.9. What is Paragraph 2 mainly about?A. The prospect of MFC.B. The developers of the plan.C. The location of the residences.D. The barriers to the construction.10. What can we infer from the underlined words?A. MFC will keep waves away.B. MFC will make use of waves.C. MFC will adjust to the waves.D. MFC will work as water breakers.11. What's the writing purpose of this passage?A. To introduce a construction program.B. To appeal to people to protect nature.C. To seek international help forMaldives.D. To report the achievement of a city plan,DScientists have recently discovered thatAndean condors (秀鹫)— some of the world’s largest birds——barely flap their wings at all while flying. Instead, they use rising air currents to remain in the air for hours.The Andean condor is the world’s largest soaring bird. They can weigh up to 15 kilograms. Their wings, when spread out, measure up to three meters. Their main food source is the meat of large animals which have died.Soaring high in the sky allows condors to easily spot possible meals on the ground.Scientists worked together to study the flight patterns of these huge birds and how much effort the birds use when flying. To study the birds while they were in the sky, the researchers attached special devices which could record every beat of their wings.The scientists learned that most of the condors’ flapping— over 75%— came when the birds were taking off. Once in the sky, the birds flew for very long periods of time without flapping at all. In fact, they only flapped their wings for 1% of the time they were in the air. One bird flew for over five hours without flapping, covering nearly 117miles.Soaring without flapping is important because birds bum energy every time they flap their wings.The birds’ soaring isn’t magic. They use the fact that hot air rises to keep themselves up. As hot air rises, it often creates “thermals”— currents of warm air moving upward. The condors soar by making use of these thermals. The tricky part is finding thermals and moving between them.When birds are forced to land and take off again often, it costs them a lot of energy. The researchers learned that to avoid having to land, the condors did most of their non-take-off flapping when they were closer to the ground and looking for a new thermal.The scientists reported that even though all of the condors they studied were young, they knew well how to take advantage of the air currents.12. What can we learn about the Andean condor from the text?A. They live mairly on small animals.B. Their wingspan is at least three meters.C. They rely on hot air to remain high in the sky.D. They are the birds with the strongest flying ability.13. Why was the equipment tied to the birds?A. To measure how far they could fly without flapping.B. To keep track of how often they flapped while flying.C. To calculate the energy required for their flight.D. To confirm their flight patterns.14. Which of the following acts consumes the most energy for a condor?A. Hunting for food.B. Flying in the sky.C. Getting off the ground.D. Landing on the ground.15. What can we infer from the text?A. Condors flap the most when looking for a new thermal.B. No condor can fly for more than five hours without flapping.C. Condors don’t need to look for thermals when soaring in the sky.D. Soaring by using thermals is probably a natural ability of condors.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。
