2020-2021学年陕西省西安中学高三英语三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AAmid the coronavirus outbreak, the U. S. Department of Homeland Security recommends having at least a two - week supply of water and food.PotatoesShelf life：2 to 5 weeks if stored in a cool, dry, dark placeYukon Gold, red, and fingerling potatoeswill last from two to three weeks. Larger white potatoes can last for three to five weeks. Sweet potatoes have about the same shelf life. Don't store them next to onions, however. The two might go together well in cooking, but raw, each gives off gases and moisture that might cause the other to spoil faster.Tea※Shelf life：6 to 12 months past "sell - by" dateDried tea leaves, whether loose (in a sealed container) or in teabags (in an unopened box) can easily last a year or more if they' re not subjected to damp or humidity. However, the tea does tend to lose flavor over time.Peanuts● Shelf life：1 to 2 monthsPeanuts in their shell, especially when kept cool and dry, are perfectly happy in the cupboard for as long as two months.Canned fruits and vegetables● Shelf life：1 to 2 years past "sell - by” dateCanning is an extremely efficient means of preserving food. Generally speaking, if canned foods aren't subjected to extreme heat, their contents should stay good for two years or more. Be aware, however, of dented cans or those with swollen tops, which may indicate the presence of bacteria inside.1. Which can go bad faster if stored with onions?A. Potatoes.B. Tea.C. Peanuts.D. Canned fruits and vegetables.2. What is special about tea?A. The flavor of tea can always remain the same.B. Tea leaves are better to be preserved in an open jar.C. Tea leaves should be kept away from the state of being wet.D. The maximum length of time that tea can be stored is 6 months.3. What may shorten the "sell - by” date of canned foods ?A. Shapes of cans.B. Categories of foods.C. Decline of the temperature.D. Exposure to high temperature.BPlanned missions to the moon need to hurry up to avoid hitting one of the busiest periods for extreme space weather, according to scientists conducting the most in-depth ever research on solar storm timing.Scientists at theUniversityofReadingstudied 150 years of space weather data to look into patterns in the timing of the most extreme events,which can be extremely dangerous to astronauts and satellites. This new research on space weather timing allows predictions to be made for extreme space weather. Therefore, it could be used to plan the timing of activities, which could be affected by extreme space weather, for example, major space missions.The researchers found for the first time that extreme space weather events are more likely to occur early in or late solar cycles-such as the one just starting. The findings may have influences on the NASA-led Artemis mission. It plans to make humans return to the moon in 2024, but can be put off to the late 2020s.Professor Mathew Owens, a space physicist at theUniversityofReading, said, “Until now, the most extreme space weather events were thought to berandomin their timing. Though there is no set pattern of the events, this research suggests they are more predictable.”In the new study, the scientists used a new method applying statistical modelling to storm timing for the first time. Previous research generally focused on how big extreme space weather events can be, based on observations of previous events. Predicting their timing is far more difficult because extreme events are rare, so there is ly little historic data to identify patterns. The findings suggest that any major planned space missions , which is beyond the next five years, will have to consider the higher probability of extreme space weather late in the present solar cycle between 2026 and 2030.4. What can we learn about the study from the first two paragraphs?A. It has lasted just 150 years.B. It doesn't refer to space weather data.C. It shows space weather has no effect on astronauts.D. It makes it possible to predict extreme space weather.5. Why might the NASA-led Artemis mission be put off?A. To research solar cycles.B. To avoid effects of space weather.C. To meet the needs of the astronauts.D. To make humans return to Earth in 2024.6. What does the underlined word “random“ in paragraph 4 probably mean?A. Irregular.B. Easy.C. Limited.D. Changeless.7. What can we infer from the last paragraph?A. The study is useful for future space missions.B. The planned space missions should be put off.C. Extreme space weather will happen before 2026.D. Previous observations make no difference to the study.CWhena person in the United States gets the COVID-19 vaccine (疫苗), the person receives a small piece of paper called a “COVID-19 Vaccination Record Card”.It is a piece of paper with the logo of the Centers for Disease Control and Prevention, or CDC, and the name and date of the vaccine. Because it is so simple, it could be easy to fake.Many people in theU.S.are still unsure about getting the vaccine. As universities, workplaces and other places are requiring proof of vaccination, some people are now buying fake vaccination cards without getting a shot.The Associated Press reports that students and teachers at universities around theU.S.are worried about fake cards. Sellers are using social media apps like Instagram to advertise fake vaccination cards. The prices range from $25 to $200. The AP notes that many college students seem interested in buying the cards. On the site Reddit, one person wrote, “I need one, too, for college. I refuse to be a guinea pig.”It is reported that more than 700 universities and colleges require proof of vaccination. Most schools simply ask their students to take a photo of their card and send it to a school website. Benjamin Mason Meier is a professor at theUniversityofNorth CarolinaatChapel Hill, UNC. He studies international health policy. He said, unlike some countries, theU.S.is not using a digital system to record vaccine status. He said theU.S.is depending on “aflimsypaper card”, and students have told him they knew of others who had used fake vaccination cards. Rebecca Williams also works at UNC. She is a researcher at the school’s Center for Health Promotion and DiseasePrevention. She said she was not surprised that people were worried about fake vaccination cards. “This is why I think the development of a reliable national digital vaccine passport app is very important,” she said.There is a law that should prevent people from making false vaccination cards. If someone uses the CDC logo without permission, they can be lined and punished by up to five years in prison. The U.S. Department of Justice recently charged a person inCaliforniawith making fake vaccination cards.College students who already have the vaccine are criticizing those who would rather spend money to buy a fake than get a free shot. Maliha Reza is an electrical engineering student atPennsylvaniaStateUniversity, She called those students “dumb”. “I’m angry about that,” she said. “Like, there is more anger than I could describe now.”8. Why do some college students buy fake vaccination cards?A. They are easy to get.B. Many Americans are still uncertain about getting the vaccine.C. Students have an interest in the fake vaccination cards.D. To get a vaccine shot is expensive.9. Which of the following measures can NOT be used to stop the fake cards?A. Having a law that should prevent people from making false vaccination cards.B. Developing a reliable national digital vaccine passport app.C. Using a digital system to record vaccine status.D. Having all the students take a photo of their vaccination card and send it to the school website.10. What does the underlined word “flimsy” probably mean?A. Weak.B. Effective.C. Detailed.D. Professional,11. What might be the writing purpose for the news report?A. To promote a digital system to record the vaccination shots.B. To explain why theU.S.should prevent making the fake vaccination cards.C. The stress the influence of the COVID-19 vaccination.D. To reduce theU.S.university leaders’ worry about fake vaccination cards.DUK physicist Isaac Newton once said, ''Nature is pleased with simplicity and nature is no dummy (傻子). '' Indeed, Mother Nature can provide almost everything human beings need if we follow her rules. But if we breakthe rules, she is likely to be cruel andlash out at us.The outbreak of the novel coronavirus pneumonia (新型冠状病毒肺炎, NCP) in China and some other countries at the beginning of this year is an example. According to Xinhua News Agency, the new coronavirus is similar to a virus found in a bat in 2017 and probably has an intermediate host (中间宿主). It's believed that the virus originated from the Huanan Seafood Market in Wuhan, Hubei province, where live wild animals were sold.The Wall Street Journal reported that Dr Peter Daszak, president of the US-based health organization EcoHealth Alliance, said, ''This outbreak is a lesson for us. On a global scale, human population density, wildlife diversity, and land use change are what drive new pandemics (流行病). ''In ancient times, people needed to rely on nature to survive so they held it in awe (敬畏). For example, the American Indians believed that humans are a part of nature and nature is a part of humans. Chinese ancients always pursued the harmony between nature and human beings.However, as human beings master more knowledge and make more advanced tools, people try to change and even conquer nature. They use more land to make buildings, genetically modify (改变) plants, capture some wild and rare animals to suit their own needs. In this process, humans gradually lose contact with nature and even throw it out of balance. For example, cutting a large number of forests means carbon dioxide must build up in the atmosphere and it contributes to global warming.Although we don't know for sure what first caused the NCP outbreak, Brian Lamacraft at Medium said it's time for people to ''reflect on our relationship with our planet'' and ''reconnect with this world and everything that we've been given''. After all, according to US poet Gary Snyder, ''Nature is not the place to visit. It's our home. ''12. What does the phrase ''lash out at'' in Paragraph 1 probably mean?A. punishB. controlC. testD. challenge13. What lesson did Daszak think human beings should learn from the NCP outbreak?A. Bats are one of the most dangerous wild animals.B. It's impossible to prevent new pandemics globally.C. We should stop the wildlife trade around the world.D. Humans should live peacefully with nature.14. What is the main idea of Paragraph 5?A. How human beings become their own masters.B. How human activities cause global warming.C. How human beings break the balance of nature.D. How humans use technology to improve their lives.15. What is the author's purpose in writing this article?A. To reflect on the NCP outbreak.B. To explain what led to the NCP outbreak.C. To describe experts' predictions on new pandemics.D. To compare ancient and modern attitudes toward nature.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。

What was Johnston's attitude towards the stock market?A. Uncaring.B. Cautious.C. Serious.D. Concerning.CRoller coasters are popular attractions at amusement parks all over the world, and patrons （顾客）flock to them for thrills, especially in the summer. Some deaths and serious injuries have been associated with them, however, raising concerns about their safety. especially for fragile and elderly riders.Statistically, a roller coaster is not very dangerous, especially if a rider is in good physical condition. Amusement park patrons are far more likely to die in accidents on the way to the park than they are to suffer injuries on a ride, assuming that the equipment is well maintained and run responsibly. Parks run many tests on their equipment to ensure that it is safe for use, including measurements designed to determine the g-forces that riders will be subject to.There are, however, a few instances in which riding a roller coaster may be unsafe. For all riders, riding equipment that is not well maintained is risky. Before riding, it is always a good idea for riders to inspect the equipment as much as possible. They should look for signs of rust, poor repair jobs, or dirt, suggesting that the roller coaster is not well cared for. Small children are especially at risk of falling out of cars with bars, due to their small size, so their guardians must make sure that they are completely and safely restrained.Roller coasters can also be dangerous for people with heart conditions. The sense of excitement that accompanies a ride is also accompanied by an elevated heart rate, which can cause a heart attack. People with known heart conditions should talk to a medical professional about riding any rough ride, because they may be unsafe.In addition, roller coasters have been linked with the appearance of blood clots（凝块）on the brain. This occurs very rarely, but it is linked with rides that subject patrons to high g-forces or instance where a passenger was whipped around as a result of poorly secured safety equipment. Individuals who take blood thinners should avoid such attractions for this reason, and anyone who experiences repeated headaches aftera ride should mention it to a healthcare provider.28. W hy does the author believe a roller coaster is not very dangerous?A. P atrons are usually in good health.B. P arks test it regularly to make it safe for use.C. O nly minor injuries happen on a ride.D. M ost deaths are resulted from road accidents.29. What should riders do before riding?A.Determine the g-forces they will bear.B. Receive a medical examination.C. Read the directions carefully.D. Check the equipment carefully.30. When your child wants to take a roller coaster, you should .A.make him or her safely restrainedB. talk to a medical professionalC. find a car that fits his or her sizeD. check the condition for bad signsA. have a headacheB. feel tiredC. are very nervousD. take blood thinnersDResearchers have developed a GPS-enabled aerial robot that flies out over large bodies of water to drop life preservers near people who are drowning.A working prototype of the robot, called Pars, was developed by RTS Lab, and Iran-based company, which also tested the machine's capabilities in open water. Over the course of four days in August of this year, the Pars development team visited the Caspian Sea to conduct a battery of tests on its brand new prototype. The location was chosen partly because it's been the site of several tragic drownings in the past few years* like the unpleasant incident of 6 students drowning together in July, 2019.The team tested the Pars' stability during flight, the accuracy of the life preserver release mechanism, and the bot's performance in both day and night time conditions, 'Gizmag' reported. According to the researchers at RTS Labs, the prototype bot met their expectations perfectly. The Pars was able to fly for 10 minutes at a top speed of 10 m/s before needing to recharge. This gives it a maximum range of 4. 5 km, making it ideal for emergencies occurring along coastlines and near ships at sea.treacherous（危险的）waters with ease. When conducting a trial rescue mission, the drone（无人驾驶飞机）was able to reach a target 75 m away and drop its payload in about 22 seconds, while a human lifeguard took 91 seconds to swim to the same location.During testing at night, the Pars was also able to illuminate（照亮）targets on the ground and make itself more visible to its controller on land using several bright LEDs. While the aerial bot cannot pull anyone to safety just yet, it could be sent out ahead of rescue crews to provide some initial aid.32. For what purpose do the researchers develop Pars?A. To make the work of lifeguards easier.B. To provide quick aid to drowningpeople.C. To pull drowning people to safety.D. To find drowning people for lifeguards.A. drowning accidents happened here a lotB.it is a good site for swimmingC. it has large open waterD.it is near the research center34. What can we infer from the Paragraph 3?A. Pars needed recharging too often.B. Pars couldn't fly over a long distance.C. Pars can only be used near coastlines.D. The researchers were happy with Pars' performance.35.What does the underlined part "flesh and blood counterparts" in Paragraph 4 refer to?A. Normal robots.B. Swimmers.C. Human lifeguards.D. Drowning people.第二节（共5小题；每小题2分，满分10分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。

2020年陕西省西安中学高三英语三模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ALast summer, Katie Steller pulled off the freeway on her way to work inMinneapolis. She stopped at a traffic light, where a man was sitting with a sign asking for help. She rolled down her window and shouted. “Hey. I’m driving around giving free haircuts. Do you want one right now?” The man laughed, then paused. “Actually,” he said, “I was really hoping to get a haircut.” Steller pulled out a red chair from her car and helped the man cut his hair immediately. After the work was done, the man looked in a mirror. “I look good!” he said.Up to now, Steller has given 30 or so such haircuts around the city to people with little influence, and she is strongly aware of the power of her cleanup job.As a teen, she suffered from a severe disease, causing her hair to get thinned, so her mother arranged for Steller’s first professional haircut. “To sit down and have somebody look at me and talk to me like a person and not just an illness, it helped me feel cared about and less alone,” she says. After that, Steller knew she wanted to have her own barbershop so she could help people feel the way she’d felt that day. Not long after finishing cosmetology (美容术) school in 2009, she began what she now calls her Red Chair Project, reaching out to people on the streets. Her aim was that by doing some kind acts, others would be inspired to spread their own.“Part of what broke my heart was just how lonely peoplelooked,” she said. “I thought maybe I’d go around and ask if people want free haircuts. I can’t fix their problems, but maybe I can help them feel less alone for a moment.”It all began with a belief in simple acts of kindness, such as a free haircut. “The way you show up in the world matters,” said Steller. “You have no idea what people are going to do with the kindness that you give them.”1. How does the writer begin the passage?A. By making a comparison.B. By giving a reason.C. By raising a question.D. By describing a scene.2. What made Stellar start the Red Chair Project?A. Her mother’s love for her.B. Her interest in cosmetology.C. Her care for those in need.D. Her wish to fight severe diseases.3. What did Stellar expect from the project?A. To spread kindness.B. To solve social problems.C. To deal with relationships.D. To make people look smarter.BThe idea came to him when he least expected it. Alvin Irby was at a barbershop when he saw one of his former students sitting in the shop with a bored look on his face. That’s when Irby realized that by pairing barbershops and books, he might be able to inspire young boys to read.Alvin Irby, a former kindergarten and first-grade teacher, knows how important it is for young children to read. He also knows that young boys in particular often don’t have adult male role models who inspire them to read. “Many young boys may literally never see a man reading in school during the years when they’re learning to read because there are so few male elementary school teachers,” Irby toldMashable.That’s where the barbershops come in. Four years ago, Irby launched Barbershop Books as a way to not just get books into the hands of young boys, but also to create community reading spaces in a place where kids go frequently. Since itsinceptionin 2013, the program has created kid-friendly reading spaces in 50 barbershops in 12 states throughout the United States.Irby isn’t the first person to see the connection between barbershops and books and boys. Hair stylist Courtney Holmes, launched a program a few years ago offering free haircuts to kids as long as they read to him while he cuts their hair.That’s the kind of environment that Irby wants to promote with his program. The reading spaces created by Barbershop Books help to spark an interest in books by showing kids that reading is about more than just spelling and vocabulary skills, it’s about making reading a low-stress activity that can help them relax, laugh and have fun.“Our belief is that if we can create positive reading experiences early and often for young boys, then they will choose to read for fun,” Irby noted, adding, “This is really what Barbershop Books is about, getting young boys to say three words: I’m a reader.”4. What happened to Alvin when he was at a barbershop?A. He found it easy for young people to get bored.B. He offered a barbershop to his former student.C. He thought of a way to encourage young readers.D. He realized the importance of reading for young boys.5. What is the function of Barbershop Books?A. To attract more customers who love films.B. To provide free haircuts to book lovers.C. To show the influence of reading on children.D. To create a reading environment fbr children.6. It can be inferred from the passage that ________.A. reading is a low-stress activity that is relaxingB. Barbershop Books is only suitable for young boysC. Irby attaches great importance to school educationD. Barbershop Books can arouse (引起) young people’s interest in reading7. What does the underlined word “inception” in the 3rdparagraph mean?A. discovery.B. success.C. popularity.D. beginning.CIn 2002, young Elon Musk tried unsuccessfully to buy Russian rockets to help him send mice to Mars and back. Afterwards, the youngmillionaire decided to build his own rockets.Musk went to Southern California and started hiring people to help bring his dream to life. In a very short time, and despite some failures, his company SpaceX launched Falcon 1, the first successful privately-built liquid fuel rocket, into Earth's orbit in 2008.As the first Falcon rocket began testing, development was already underway for the Falcon 9. This much larger rocket, which uses nine engines to lift heavy payloads（有效载荷）into orbit, is engineered to return to Earth, ready to be reused for another flight.For Musk, space is the final destination. To help people get there, his company Neuralink is developing devices that will link people's brains with computers. A similar device has been developed at the University of Utah. It consists of a chip（芯片）with 256 threads（线程）that is placed between a person's skin and brain. The threads attach directly to brain tissue（脑组织）.Patients who have the device are able to use only their minds to communicate with one another through computers.Neuralink's chips will have about 1,000 threads. A robot developed by the company will place up to ten chips under a person's skin. The chips will communicate without wires but with a tiny device that will be worn behind the person's ear. That device, in turn, will communicate with computers. The primary market for the technology will be for people that, because of injuries or birth defects, cannot control their hands and arms. With Neuralink^ product, they'll be able to mentally command a computer to type messages for them or carry out other tasks.8. According to this article, what was the first Falcon 1 able to do?A. Launch big satellites.B. Reach distant moons.C. Move around our planet.D. Study the universe.9. What does the article explain about Neuralink's chips?A. How they'll be set up.B. What safety features they'll have.C. How much money they'll earn.D. Where they'll be produced.10. According to this article, who is Neuralink going to market its product to first?A. Those who own great wealth.B. Those who are physically disabled.C. Those who travel internationally.D. Those who do research on plants.11. In which publication is this article most likely to appear?A. The Journal of Environmental Studies.B. Advances in Business and Technology.C. Digest of Fashion and Entertainment News,D. Consumer's Guide to Outdoor Recreation.DScientists have discovered a new behaviour among bumblebees that tricks plants into flowering early.When lack of pollen, bumblebees will bite little by little on the leaves of flower-less plants. The damage seems to fool the plant into flowering, sometimes up to 30 days earlier than normal.With their hairy appearance and special sounds, bumblebees are hard to miss in gardens all over the world. Their hairy bodies make them excellent pollinators for crops like tomatoes and blueberries. They are among the first bees to appear each year and work a long season.But despite their key role, bumblebees, like many other pollinators have seen their numbers decline suddenly in recent decades. One recent study pointed to climate change, reporting that an increasing number of hot days in Europe andNorth Americawas raising local bumblebees extinction rates.But researchers have now made a discovery about bumblebees that could have something to do with their long term survival. Scientists inSwitzerlandfound that when the bumblebees were out of pollen, they started to bite on the leaves of plants that hadn't yet flowered. They used their mouths to cut clearly-shaped holes in the leaves. But the creatures didn't eat the material or use it in their nests.The damaged plants responded by flowering earlier than normal--in some cases up to 30 days ahead of schedule. Researchers also found that the bee damaged plants flowered 30 days earlier than undamaged plants and 25 days earlier than ones damaged by the scientists.“I think everything that we've found is consistent with the idea that the bumblebees are damaging the plants and that that's an adaptation that brings flowers earlier and that benefits the bees,” said Dr Mark Mescher, one of the authors from ETHZurich.12. How do bumblebees fool plants into flowering earlier?A. By making use of the hot weather.B. By putting the false flowers on the leaves.C. By attacking the leaves of flowerless plants.D. By taking away the pollen from the other flowers.13. What's bumblebees’ key role?A.Making plants flower early.B. Spreading pollen to flowers and plants.C. Sending information about weather change.D. Finding out whether the plant has flowers.14. What has happened to bumblebees in the past the years?A. They are becoming homesick.B. They are not as friendly as before.C. There is a sharp decrease in number.D. They have been busy year by year.15. What's Dr Mark Mescher's attitude towards the behaviour of bumblebees?A. Uncaring.B. Skeptical.C. Tolerant.D.
