2021届陕西省西安中学高三英语一模试卷及答案解析第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AOne day when I was 5, my mother blamed me for not finishing my rice and I got angry. I wanted to play outside and not to be made to finish eating my old rice. When angrily opening the screen door (纱门) with my foot, I kicked back about a 12-inch part of the lower left hand corner of the new screen door. But I had no regret, for I was happy to be playing in the backyard with my toys.Today, I know if my child had done what I did, I would have blamed my child, and told him about how expensive this new screen door was, and I would have delivered a spanking (打屁股) for it. However, my parents never said a word. They left the corner of the screen door pushed out, creating an opening, in the defense against unwanted insects.For years, every time I saw that corner of the screen, it would constantly make me think about my mistake. For years, I knew that everyone in my family would see that hole and remember who did it. For years, every time I saw a fly buzzing (嗡嗡) in the kitchen, I would wonder if it came in through the hole that I had created with my angry foot. Iwould wonder if my family members were thinking the same thing, silently blaming me every time a flying insect entered our home, making life more terrible for us all. My parents taught me a valuable lesson, one that a spanking or stern (严厉的) words perhapscould not deliver. Their silent punishment for what I had done delivered a hundred stern messages to me. Above all, it has helped me become a more patient person and not burst out so easily.1. When the author damaged the door, his parents _______.A. gave him a spankingB. left the door unrepairedC. told him how expensive it wasD. blamed him for what he had done2. The experience may cause the author _______.A. not to go against his parents’ willB. to have a better control of himselfC. not to make mistakes in the futureD. to hide his anger away from others3. What is the main idea of this text?A. Parents is the best way to solve problems.B. Parents are the best teachers of their children.C. Adults should ignore their children’s bad behavior.D. Silent punishment may have a better effect on educating people.BThe idea of growing food in a desert would make most people laugh but this is quickly becoming a reality. There are currently two desert farms in the world where quality vegetables are being planted cheaply and easily.Sundrop Farms, based in South Australia, uses experimental greenhouses to grow tomatoes, peppers and cucumbers. The biggest challenge of growing food in a desert, obviously, is the lack of available water. The researchers at Sundrop Farms have gotten aroundthis problemby using the sun to desalinate (淡化) sea water. It can also be used to control the temperature of the greenhouses.Without depending on limited resources such as land and fresh water Sundrop Farms has made farming a practice. This can increase the world’s food supplies. Another benefit ofthis kind of farming is that it can be done anywhere, thus reducing the costs of transporting food to distant locations. Yet another benefit is that it reduces the need for pesticides (杀虫剂).Another experimental desert farm is the Sahara Forest Project, which began in Qatar in December 2012. Greenhouses in the farm are cooled by saltwater. Solar power and other technologies are used together to help make vegetation (植被) grow in the desert environment. As deserts have expanded over recent years around the world due to global warming, this project could solve the problem.The result form the Qatar project were better than expected and in June of 2014, Jordan agreed to host another one. This will be much bigger than the Qatar project and the project members will have even more opportunities to test their experiments on a much larger scale. It is not clear yet that desert farming resents the future of farming but these projects have shown some success in the field.4. What does “this problem” in paragraph 2 refer to?A. Sea water is bard to purify.B. The desert is short of water.C. The temperature is high in the desert.D. Desert farms aren’t fit to plant vegetables.5. What is one of the characters of desert farming?A. It needs more pesticides.B. It saves delivery costs.C. It has a location limit.D. It solves food waste problems6. What can we know about the Sabara Forest Project?A. It lives up to expectationsB. It can help produce more foodC. It is started to prevent global warmingD. It uses technology to produce saltwater7. What can be inferred about desert farming from the last paragraph?A. It still has problems to solve.B. It represents the future of farming.C. Its early success has aroused interest in it.D. Its aim is to create more job opportunities.CAlthough computer technology is often necessary today, using a pen or pencil activates more areas of your brain than a keyboard does. You can potentially remember more by handwriting, according to a new study.The potential benefits of handwriting for memory have been debated for some time. The new study set out to answer one question: How does handwriting compare to using a keyboard when it comes to remembering new information?In all,24 participants took part. Researchers asked each of them to write with a pen and then each was also asked to type on a keyboard. While performing these tasks, each volunteer wore a cap that held electrodes next to their head. It looked somewhat like a hair net fitted with 256 sensors. Those sensors recorded the participants' brainwaves. The electrodes noted which parts of the brain turned on during each task. And they showed that writing turned on memory areas in the brain while typing didn't.Audrey van der Meer, the new study's leader, says this suggests that when we write by hand, we remember better. “This is because writing involves complex movements that activate more areas of the brain. The increased brain activity gives the brain more ‘hooks’ to hang your memories on,” she explains. Van der Meer also points out that writing by hand is related to visual notetaking. “Rather than typing blindly, the visual notetaker has to think about what is important to write down. Then, key words can be interlinked by boxes, arrows and small drawings,” she adds.This study does not recommend banning digital devices. In fact, its authors point out, computers and other devices with keyboards have become necessary in modern society. Keyboarding can especially benefit those with certain special needs (such as if they have trouble using their hands) and typing beats writing when it comes to speed, they add.8. Why were participants asked to wear caps in the study?A. To record their brainwavesB. To inform them of their tasksC. To allow them to focus on writingD. To protect their heads like hair nets9. What does Audrey van der Meer try to explain?A. Why handwriting is more complex than typingB. Why the brain works when it comes to learningC. Why handwriting helps remember informationD. Why key words are helpful to visual notetaking10. What is the study's authors' view on typing?A. It relieves people's handsB. It remains vital and helpfulC. It is not worth recommendingD. It is more challenging than writing11. Which of the following can be a suitable title for the text?A. How Can You Remember New Information?B. Handwriting Benefits Health in the LongRunC. Should Typing Take the Place of Handwriting?D. Handwriting Is Better for Memory Than TypingDWhen 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 to believe 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 gracefullyoff 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。

Elion spent her early youth in Manhattan. She attended senior high school and had, in her words, an unbelievable thirst for knowledge.Influenced by the death of her grandfather, who died of cancer, Elion entered Hunter College at the age of 15 and graduated in chemistry at the age of 19. She had difficulty finding employment after graduation because many laboratories refused to hire women chemists. She found a part-time job as a lab assistant and went back to school at New York University. Elion worked as a high school teacher for a few years after finishing work on her master’s degree.The start of World War II created more opportunities for women. At the age of 26, Elion was able to get a job at Burroughs Welcome, where she began a 40-year partnership with Dr. George H. Hitchings. Her thirst for knowledge impressed Dr. Hitchings, and he permitted her to take on more responsibility.Elion and Hitchings set out on a course of creating medicines by studying the chemical composition of diseased cells. Rather than relying on old trial-and-error methods, they used the differences in biochemistry between normal human cells and pathogens(病原体)to design medicines. In all, Elion obtained 45 patents on medicine and was awarded 23 honorary degrees.In 1988, Elion received the Nobel Prize for Medicine, together with George H. Hlitchings and Sir James Black. She received other awards for her work, including the National Medal of Science in 1991, and that same year, she became the first woman to beabsorbed into the National Inventors Hall of Fame.

A report published this week suggests that climate change has a negative effect on our mental health, too.The study, published in the journal Proceedings of the National Academy of Sciences of the United States(PNAS), links an increase in monthly temperatures to a rise in mental health issues. The experimental evidence stems from meteorological (气象的) data paired with information collected from nearly 2 million randomly sampled residents in the United States. The data was collected over the span (跨度) of a decade.“We find that experiences with hotter temperatures and added rainfall each worsen mental health, that long-lasting warming associates with an increased popularity of mental health issues, and that exposure to tropical cyclones(热带气旋), likely to increase in frequency in the future, is linked to worsened mental health,” authors of the study stated. “These results provide added large-scale evidence to the growing link between climate change and mental health.”The report specifically focused on mental health outcomes due to the effects of environmental stress - such as temperature, rainfall, and tropical cyclones - but other climate change-related issues are likely to affect mental health as well - specifically, the stress and anxiety of knowing natural disasters could be more frequent as temperatures rise.8．From the newly-published report, we learn that the climate change may _________.A．save a lot of people’s livesB．cause unbelievable disastersC．influence people’s mental healthD．greatly change people’s life styles9．Why did the author mention “the span of a decade” in Paragraph 2?A．To stress the importance of the study.B．To show that the study cost too much money.C．To explain the difficulties and hardships of the study.D．to indicate that the study is objective and believable.10．Where can we find some specific results of the study?A．In Paragraph 1B．In Paragraph 2C．In Paragraph 3D．In Paragraph 411．What can we infer from the last paragraph?A．The study has its limits.B．The results of the study aren’t satisfactory.C．The environmental problems can’t be solved.D．Mental health is determined by climate change.Your child is unique, but what all children have in common is natural curiosity(好奇心)and an ability to learn they are born with. Our brains are active all the time, and a baby’s brain is the busiest of all. Research has shown that babies begin to understand language about twice as fast as they actually speak it. By showing children other languages at an early age, you are giving them the opportunity to make use of their natural ability to hear and recognize (辨认)between the sounds of other languages, and their ability to make sense of what they are hearing.Communication is something that children do to help them achieve something else, and they are unaware of the large amount of learning taking place. They take everything inthrough their senses, making connection between what they hear, see, smell, taste and touch. As long as we provide the right conditions, their learning and development will take place in a natural way.In your child’s early years, the emotional environment is just as important as the physical environment. Children learn when they feel safe, happy, valued and listened to. This is central to any learning experience in child’s early years, including learning an additional language. Your child has a trial (试验)-and-error approach to its development, and making mistakes is a valuable part of the learning process. When children learn an additional language at an early age, they get the benefits of experimenting with that language as a natural part of their development. Their progress isn’t prevented by a fear of getting it wrong, a nd very young children are simply working their way towards getting it right.The long-term benefits of learning another language go beyond being able to communicate with others. Studies suggest that children learning an additional language tend to score better on standardized tests because learning languages develops listening, observation, problem-solving and critical (批判性的)thinking skills. These are skills that are of life-long benefit, both personally and professionally. Encouraging in children a love of language at an early age prepares them well for school and for life.12．what do we know about Children according to Paragraph 1?A．Children are busy playing.B．Children are born to speak.C．Children are good at speaking native language.D．Children live a better ability to learn other languages.13．While learning a language, children ________ .A．spook to themselves B．need to have language classesC．make use of their different senses D．notice how much they have learned 14．Children learn when they________.A．are in bad emotion B．need to have language classesC．learn from their mistakes D．are taught by their teachers15．In fact learning another language helps children to________.A．take more tests B．have a good timeC．encourage themselves D．develop life-long skills二、七选五Small Talk Might Get You Big RewardsIn many culture, small talk is a big deal. Although it may seem like a pointless conversation to pass the time or avoid awkward silence, it is actually very important for communicating and bonding with others.According to US inspirational speaker Melissa Wadsworth, “Small talk is about tapping into possibility.” Having good small talk skills is the best way to meet new people, which can lead to friendships, jobs, or other goals. 16If small talk is so important, how do you do it? What’s the best way to break the ice and start talking to people? Well, some of the most common topics include the weather, hobbies, work, family and travel. 17 It’s easy for people to talk about them.18 For example, you can talk to your schoolmates about your classes or that teacher who drives everyone crazy. 19 If you’re lucky, you might have a friend introducing you to others firstly to help you start a conversation.Sometimes, it may seem a bit difficult to start a conversation with someone you don’t know. That’s OK! 20 Wadsworth has the best advice for this: “approach the conversation excited about the friendship, the good laugh, the fascinating story, the job opportunity, the date, the joy or the sense-of-belonging potential inherent (内在的) in this shared experience.”Small talk might just be the first step to something much bigger.A．Everyone has this problem sometimes.B．Another way to start small talk is to comment on your surroundings.C．These topics are great for small talk because they are valuable.D．Small talk can also be used for striking up a conversation.E．Not only that, small talk is shown to boost brainpower by encouraging empathy, making you consider what another person feels or thinks.F．Nobody would doubt the values of small talk.G．If you’re at a party, you might comment on the snacks, music, or the number of people there of video games.三、完形填空阅读下面短文，掌握其大意，然后从16－35各题所给的A．B．C．D四个选项中，选出最佳选项。

At our new, monthly membership program, you'll join MoMA staff and fellow members for lively discussions about our collection and exhibitions. Ask questions, share your thoughts, and broaden the mind. A live Q&A, with Michelle Kuo and Anny Aviram, about shape and its role in MoMA's collection is also arranged.Draw, Write, and Connect with OthersExperiment with drawing and writing exercises as ways to connect with others, even when physically distant, in this 45-minute online workshop. This workshop is part of the Creativity Lab at Home plan. This session is led by Francis Estrada, Assistant Educator, and Hannah Fagin, Coordinator.

Parent participation is encouraged in this online event. Don' miss the opportunity to spend meaningful time with them.The Human ShelterIn 2016, MoMA opened Insecurities: Tracing Displacement and Shelter, an exhibition that examined how contemporary architecture arid design addressed ideas of shelter in light of global refugee(难民) emergencies. Danish Boris Benjamin Bertram documented the exhibition, and the result is a movie by him asking what makes a home, and, perhaps more importantly, when shelter becomes home. This online event is part of Member events.1.What is special about How to Look at Shape?A.It provides an interactive part.B.It is accessible to everyone.C.It is organized by Michelle Kuo.D.It focuses on MoMA's new collection.2.Which event is family-friendly?A.The Human Shelter.B.How to Look at Shape.C.Storytelling Through Art.D.Draw, Write, and Connect with Others.3.In which aspect might Bertram do well?A.Shelter design.B.Storytelling.C.Art education.D.Film-making.BMove over, helicopter parents. “Snowplow (扫雪机) parents” are the newest reflection of an intensive (强化的) parenting style that can include parents booking their adult children haircuts, texting their college kids to wake them up so they don’t sleep through a test, and even calling their kids’ employers.Helicopter parenting the practice of wandering anxiously near one’s children, monitoring their every activity, is so 20th century. Some rich mothers and fathers now are more like snowplows: machines moving ahead, clearing any difficulties in their children’s path to success, so they don’t have to suffer failure, frustration (挫折) or lose opportunities.It starts early, when parents get on wait lists for excellent preschools before their babies are born and try to make sure their kids never do anything that may frustrate them. It gets more intense when school starts: running forgotten homework to school or calling a coach to request that their children make the team.Rich parents may have more time and money to devote to making sure their children don’t ever meet with failure, but it’s not only rich parents practicing snowplow parenting. This intensive parenting has become the most welcome way to raise children, regardless of income, education, or race.Yes, it’s a parent’s job to support the children, and to use their adult wisdom to prepare for the future when their children aren’t mature enough to do so. That’s why parents hide certain toys from babies to avoid getting angry or take away a teenager’s car keys until he finishes his college applications.But snowplow parents can take it too far, some experts say. If children have never faced a difficulty, what happens when they get into the real world?“Solving problems, taking risks and overcoming frustration are key life skills,” many child development experts say, “and if parents don’t let their children experience failure, the children don’t acquire them.”4. What do we know about snowplow parenting?A. It appeared before helicopter parenting.B. It costs parents less than helicopter parenting.C. It was a typical phenomenon of the 20th century.D. It provides more than enough services for children.5. What is mainly discussed about snowplow parenting in Paragraph 4?A. Its cost.B. Its benefits.C. Its popularity.D. Its ending.6. Why does the author mention parents’ taking away car keys?A. To show teenagers are no better than babies.B. To advise teenagers not to treat their cars as toys.C. To advise parents not to buy cars for their teenagers.D. To show it’s appropriate to help children when necessary.7. What’s the possible result of snowplow parenting according to the experts?A. Children lacking problem-solving ability in reality.B. Children mastering more key life skills than parents.C. Children gaining great success in every aspect of life.D. Children meeting no problems or frustration after growing up.CI got my first bike when I was nine years old. Jimmy, the bike, was my first love. I rode it everywhere. The suburb, the back lanes, the fields and forests, the river paths and swampland were far more exciting than any adventure novel or television series.There’s nothing quite like the relationship between a child and his bicycle and the endless happiness two wheels and a pair of strong legs offer. No video or computer game can replace the liberation of being alone on a bicycle.As parents, to deny children the simple pleasure of riding a bike is a failure of our responsibilities to raise independent and stable young citizens. We should offer our children a healthy alternative to hours in front of an addictive screen. Studies have shown that cycling promotes not only muscle growth but brain growth. Guess which country has children with the best mental health outcomes and is regularly the top of listings of the happiest young people. No surprise it’s theNetherlands, the unquestioned leader among industrial countries in encouraging bicycle use.Our dependence on cars has degraded the public transport system, polluted our sky, led to the untimely death of thousands every year, and denied children safe access to their suburbs. A recent study found that 69% of children were accompanied to school. The same study found that a similar number of parents drove to work.In some regions ofJapan, when children start their first year of school, parents are expected to walk with them for the first few weeks, introducing them to residents and shopkeepers along the chosen route, letting thecommunity take care of these children. However, driving children to school isproscribed. Children can choose to ride a bike or walk to school after they are familiar with the community, and it’s the community’s role to keep them safe.Therefore, I strongly advise the government to provide better infrastructure (基础设施). Build separated cycle lanes, decrease speed limits, and design street scapes that favour people over cars. The results will be less pollution, quieter suburbs, a healthier population and, best of all, happy and independent children.8. What can we infer about the author from the text?A. He was addicted to computer games.B. He liked taking adventurous trips in nature.C. He had great fun exploring the outside by cycling.D.He got his first birthday present at the age of nine.9. Why does the author mention theNetherlandsin Paragraph 3?A. To introduce his good way of raising independent children.B. To illustrate the great influence riding has on mental health.C. To stress the importance of being physically and mentally healthy.D. To explain cycling does best in city development in theNetherlands.10. What does the underlined word “proscribed” in Paragraph 5 probably mean?A. Recommended.B. Protected.C. Delayed.D. Forbidden.11. How does the author mainly support his idea?A. By analyzing causes.B. By listing examples.C.By giving definitions.D. By analyzing scientific data.D"Sorry, but I don't agree with you..."This is usually followed by unbearable silence and angry tears. I've always found it difficult to disagree with someone, because I don't want to lose a friend. I've found it even harder to accept it when someone disagrees with me, because my ego（自尊心）ishurt.Before the other person gets a chance to explain why she disagrees with me, my usual response would be," If you aren't able to see my point of view, then what you think isn't worth my time or consideration, either." But now I've come to realize that when a friend disagrees with me, sometimes she is simply saying, "I don't agree with the way things are done." She still respects me as a person, and is only pointing out a better way to look at a matter. However, there may be times when my friend disagrees with me because I'm against the truth. That's when needto listen to what she says.I've learned that one way to help my friend is for me to be open and honest with the other to voice my thoughts and listen to the other carefully. While we can't control how a person will respond to our views, we must learn to disagree with our friends in love. We will never feel that we are better than the other person.And that will help us to be less emotional, and more objective in the way we express our opinions.In the same way, we can also stay open to feedback（反馈）from others,knowing that our friends may be correcting us in love.Good friendships build each other up, sometimes through disagreements and honest opinions. Though I don't like being disagreed with, I'm starting to see the value of such disagreements.12. The author has found it difficult to disagree with someone because .A. he is a friendly personB. he usually hides his ideasC. he has no mind of his ownD. he wants to keep the friendship13. When a friend disagreed with him,the author used to .A. be unhappyB. argue with the friendC. break up with the friendD. explain things calmly14. The author will listen to a friend when .A. he is against the truthB. he doesn't tell the truthC. he is respected by a friendD. he does things in the wrong way15. What does the author mainly talk about in the text?A. How to keep friendship.B. How to avoid hurting a friend.C. How to express disagreements.D. How to deal with disagreements.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。

This seems amundanetask, but it brought me such joy at that time. I would excitedly turn the tap on, then brush the comb with a used toothbrush as hard as I could. Satisfied that I’d done a good job, I would proudly return the comb to Dad. He would smile at me, and place the comb on top of his wallet.About two years later, Dad started his own business. I started primary school. That was when things started to change. Dad’s business wasn’t doing so well, and he didn’t come home as much as he used to. Over the years, I stopped waiting for him to come home.Today, I’ve graduated from college and Dad’s business are better now. Yet the uncomfortable silence between Dad and me continued. Two days before my birthday last year, Dad came home early and said to me, “Hey, would you like to help me clean my comb?” I looked at him a while, then took the comb and headed to the sink. It’s a new comb. I hadn’t noticed that he’d changed it. I brushed the comb, and it hit me then: why, as a child, helping my dad clean his comb was such a joy.I passed the clean comb back to Dad. This time, I noticed my day has aged. But his smile is still as heartwarming as before. Dad carefully places his comb on top of his wallet. After so many years, I guess some things never change. And for that, I’m glad.4.

My Memory with My Dad.D. I Love My Family Members.CA new study finds almost one third of the world’s population is overweight. Since 1980, obesity rates(肥胖率)in children and adults have doubled in 73 countries, making people more worried. And rates are increasing in many other countries. Obesity is increasing faster in children than adults in many nations, including Algeria, Turkey and Jordan, the report said. But the world's weight problem is growing in both rich and poor countries alike. Researchers say an increasing number of people are dying of related health problems in what they called a "disturbing global public health problem."Researchers studied health information from 1980 through 2015. They examined obesity rates, average weight gain in 195 countries. They found that obesity rates are three times greater among youth and young adults in countries like China, Brazil and India. Almost 108 million children and more than 600 million adults were found to be overweight. Egypt had the highest number of overweight adults in 2015. Vietnam had the least. In the same year, the United States had the highest number of overweight children, and Bangladesh had the least.Yet hunger remains a problem in many areas. The United Nations said that almost 800 million people, including 300 million children, go to bed hungry each night. Experts said poor diets and lack of physical activity are mainly to blame for the rising numbers of overweight people.Growing populations have led to rising obesity rates in poor countries. Often, poor people will eat processed(加工的) foods instead of choosing a diet rich in vegetables.The London-based Overseas Development Institute studied the price of food in five countries: Britain, Brazil, China, Mexico and South Korea. It found that the cost of processed foods like ice creamand hamburgers has fallen since 1990. But the cost of fresh fruits and vegetables has gone up.8. What do we know about obesity in the world?A. It is worryingB. It is given no attentionC. It has been successfully solvedD. It is more serious among old people9. Which country has the most overweight children in 2015?A. AmericaB. VietnamC. EgyptD. Bangladesh10. What is one of the reasons why people get overweight?A. HungerB. Poor dietC. Diets with vegetablesD. Eating too much fruit11. Which ofthe following can be the best title for the text?A. It’s Important to Have a Balanced DietB. How Can We Lose Weight and Keep Fit?C. Is It Necessary for Us to Eat Fresh Vegetables?D. Nearly One Third of People in the World Are Overweight.DThe health benefits of staying active are already well-known. It can help you manage weight, keep blood sugar levels down and reduce risk factors for heart disease.Now, a new study suggests that regularly playing sports, especially badminton or tennis, is not only healthy but also reduces your risk of death, at any age, by approximately 50%. This is a big scale population study to explore the health benefits of sports in terms of death rate. The study evaluated responses from 80, 306 adults aged 30 and above inEnglandandScotland, who were surveyed about their health, lifestyle and exercise patterns.After adjusting factors such as age, sex, weight, smoking habits, alcohol use, education and other forms of exercise besidesthe named sports, the researchers compared the risk of death among people who took part in a sport to those who didn’t. The percentage of reduced risk of death was found to be: 47% for racket（球拍）sports, 28% for swimming and 15% for cycling.In addition to this, the study didn’t find any significant reduction in the risk for sports like running and football. The findings also exposed that over 44% of the participants met the guidelines for the recommended exercise levels to stay fit and healthy, which amounts to 150 minutes of moderate(适度的) physical activity in a week.Does this mean you stop running or playing football and switch to tennis instead? Every kind of sport and physical activity has different physical, social and mental benefits attached to it. The apparent lack of benefits of running and football could result from several variables that were not taken into account.Being active helps you feel happier and live longer. So, the most important step is to take part in any kind of sport that you are likely to enjoy and follow in the long term.12. How is the study conducted?A. By doing comparative experiments.B. By analyzing previous data.C. By evaluating survey information.D. By tracking participants for a long time.13. What does the underlined part “the named sports” refer to?A. Ball sports.B. Racket sports.C. Individual sports.D. Traditional sports.14. What can we infer from paragraph 5?A. Few people will play football.B. Tennis will become more popular.C. The result of this study is wrong.D. The study needs to be further improved.15. What does the author advise people to do?A. Stick to any sport that you like.B. Play badminton and tennis only.C. Stop running and playing football.D. Do any sport according to guidelines.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届西安市第一中学高三英语第一次联考试卷及答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项APeople in the Middle Ages did eat with their hands. Personal utensils (餐具) were mostly unheard of, especially forks. There were spoons to help serve, but only special guests would receive a knife from the host. Everyone else would be expected to bring their own. Of course, eating with one's hands can be quite a sticky situation, so towels were provided to help diners stay at least somewhat clean as they ate.Still, dining was often a messy affair. At special occasions in the wealthiest households, women tended to dine alone, separate from the men. Women were expected to uphold a quality of grace. Eating greasy meat by hand would certainly not help! Once the men and women had finished their meals, they would come together to socialize.Dietary scholars of the Middle Ages believed that the foods in a meal needed to be served and eaten in order of heaviness. The lightest and most easily digested foods, such as fruits and cheeses, were eaten first to help the digestive (消化) system get started. Once digestion was underway, greens and light meats, such as lettuce, cabbage and chicken, could be eaten. Last came the heavier vegetables and meats, such as carrots, beans, beef, pork, and mutton. This method was considered the most healthful way to eat.The main and largest meal of the day was supper, and it was eaten at midday. Dinner was a light meal, and many of those in nobility (贵族) -the highest levels of the Middle Ages society-skipped breakfast altogether. Breakfast was considered unnecessary for those who did not perform physical work. Snacks and any other eating during the day were viewed the same way. Commoners, or the working class, were allowed to eat breakfast and small meals throughout the day.1. What did people in the Middle Ages usually do at the dinner table?A. They cleaned hands before meals.B. They used personal utensils.C. They had to use knives at dinner.D. They ate mostly with hands.2. What is the third paragraph mainly about?A. The order of eating foods.B. The weight of various foods.C. The principles of digesting foods.D. The list of healthy foods.3. Why did the nobility avoid eating breakfast?A. Breakfast was wasted for the nobility.B. Breakfast was viewed as unnecessary.C. Breakfast was considered as a light meal.D. Breakfast was saved for commoners.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.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 insidetheir 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 reportDWith graduation days being celebrated all over the country, a student who has to use a wheelchair honored his mother on his graduation day in a special way. Easley High School graduate, Alex Mays surprised people present when he got up and walked across the stage at Clemson's Littlejohn Coliseum.“I was really happy—it made me feel good,” Alex said.Alex was not given a chance to live right from his birth. He was born at 25 weeks and weighed just 1 pound, 10 ounces at birth. When he was very young, he had a disease and lost the ability to walk. After his mother's death in 2013, Alex had several other difficult life changes until he came to live with his grandparents, Dousay and her husband, Dewayne. Dousay said that when Alex came to live with them, they decided to bring him up in the best possible way they could.Last fall, Alex said that he would walk across the stage to get his diploma to honor his late mother. He practiced hard and worked with a physical therapist for 9 months to complete his plan.The only help Alex got was from his mom's best friend, Tonya Johnson, who pushed his wheelchair to the stage wearing one of his mother's favorite shirts. “I had support from my family. I couldn't have done it without them,” Alex said.“Alex made everyone in the building feel encouraged that day” Pickens County School District public information specialist John Eby said. “The school teachers knew he was going to get up to get his diploma, but the distance he walked was a surprise, even to them,” Eby said.“Some of life's most important tests aren’t given in a classroom; Alex tested himself and passed with flying color1 s,” Eby added.12. In what way did Alex honor his late mother on his graduation day?A. By dressing like her.B. By saying sorry to her.C. By inviting her best friend.D. By walking to get his diploma.13. What can we learn from Paragraph 3?A. Alex was born healthy.B. Alex went through a lot.C. Alex had a purpose in life as a child.D. Alex has lived with his grandparents all the time.14. What did Alex also express on his graduation day?A. His big regret in life.B. His feelings for hisschool.C. His thanks for his family.D. His will to complete his study.15. Which of the following words can best describe Alex?A. Strong-minded.B. Warm-hearted.C. Cool-headed.D. Easy-going.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。

The Below Zero icecream machine uses a unique technique to freeze alcohol, which allows you to turn beers, cocktails and even spirits (烈酒) into delicious soft —serve ice cream.Rogers was trying to create a highly — caffeinated espresso ice cream flavor when he realized hecould use the same technique with alcoholic beverages. He started experimenting with various gums and stabilizers commonly used in the ice cream industry and eventually patented something called the NEA gel. It’s this magical concoction (调制品) that allows the alcohol to freeze to a near solid inside the Below Zero ice cream machine.Even though Below Zero changes the texture (质地) of beer, cocktails and even spirits, essentially turning them into soft —serve ice cream, it does not affect the alcohol contentat all. The ABV (酒精度) remains exactly the same, which means you can get drunk on ice — cream just as you would on the same concoctions in liquid form.Will Rogers claims that it takes around 30 minutes for beer to go from liquid to ice cream form, but higher alcohol content drinks take longer. Essentially, the higher the alcohol level, the longer the wait.The American inventor plans to sell Below Zero ice cream machines to bars and breweries wanting to surprise their patrons. Metro reports that machines will sell for about 6,000.4. What’s the name of the machine which can change beer and spirits into ice cream?A. Will RogersB. WDS Dessert StationsC. HinkleyD. Below Zero5. What makes alcohol to freeze to a near solid inside the machine?A. gums.B. stabilizers.C. NEA gel.D. ABV.6. What can we know from the passage?A. The machine can change all liquids into ice cream.B. It takes 20 minutes for beer to change into ice cream.C. The higher the alcohol level, the shorter the wait will be.D. The machine changes the texture of beer, cocktails and even spirits.7. What can we infer from the passage?A. The machine affects the alcohol content.B. You can get drunk if you have ice—creams made from spirits.C. The American inventor doesn’t want to sell themagical machine.D. Bars and breweries will not become potential buyers of the machine.C“Your mind is a garden; your thoughts are the seeds. The harvest can either be flowers or weeds,” William Wordsworth wrote. In the above quote, William suggests that the process of gardening mirrors human life. Depending on what we “plant” in our lives, we bloom (生长茂盛) or don’t. Before you start to work in your garden, it’s necessary to have a vision for it. Thinking of what youwant to grow in your garden and how to lay it out is a good first step in making your vision a fruitful reality. In life, you should consider what you want to create and what you want to achieve, because your mind-garden is like the white paper and the possibilities are endless. Regardless of what you choose to plant, poor soil isn’t suitable for growth. This is why gardeners take the time and energy to upgrade the soil before planting. So, creating the right soil is important to the realization of your goals and dreams. Fortunately, there are countless ways to make your personal bedrock better. Getting an education is one of the most effective ways, which can help you enrich your life’s soil.You don’t have to be an enthusiastic gardener to understand the meaning of “You reap(收获) what you sow.” When a gardener wants tomatoes, they just need to plant tomato seeds. It’s a very clear act that produces an expected result. Each of us has the power to decide which “life seeds” to plant. For example, if you plant ill seeds, it's likely that you’ll experience pain in return. Contrarily, if you plant seeds of kindness and understanding, your life will bloom with happiness and love.A gardener’s trulyarduouswork begins after the seeds are in the ground because a garden requires a lot of care and attention. Regular watering and weeding are required for a healthy garden. So, to ensure your dreams takeroot, you should be devoted, aware, and present. After countless hours and energy spent, the crops have grown well and are finally ready to be harvested.8. What is important before gardeners break ground in their gardens?A. Receiving some training in planting.B. Drawing up a good plan for their gardens.C. Having the courage to accept the worst outcome.D. Doing research on the common local garden plants.9. What is compared to getting education by the author?A. Improving the condition of the soil.B. Growing your most favorable plants.C. Taking care of the plants in your garden.D. Selecting proper goals in gardening work.10. What does the author want to express in Paragraph 3?A. Your quality of life depends on your positive action.B. Your experience can help you understand plants better.C. Your choice of soil is an important part in your gardening.D. Your knowledge of planting will make you a successful gardener.11. What does the underlined word “arduous” in Paragraph 4 probably mean?A. BeneficialB. CreativeC. Boring.D. ToughDWhy isn’t science better? Look at career incentive(激励).There are oftensubstantial gaps between the idealized and actual versions of those people whose work involves providing a social good. Government officials are supposed to work for their constituents. Journalists are supposed to provide unbiased reporting and penetrating analysis. And scientists are supposed to relentlessly probe the fabric of reality with the most rigorous and skeptical of methods.All too often, however, what should be just isn’t so. In a number of scientific fields, published findings turn out not toreplicate(复制), or to have smaller effects than, what was initially claimed. Plenty of science does replicate — meaning the experiments turn out the same way when you repeat them -but the amount that doesn’t is too much for comfort.But there are also waysin which scientists increase their chances of getting it wrong. Running studies with small samples, mining data for correlations and forming hypotheses to fit an experiment’s results after the fact are just some of the ways to increase the number of false discoveries.It’s not like we don't know how to do better. Scientists who study scientific methods have known about feasible remedies for decades. Unfortunately, their advice often falls ondeaf ears.Why? Why aren't scientific methods better than they are? In a word: incentives. But perhaps not in the way you think.In the 1970s, psychologists and economists began to point out the danger in relying on quantitative measures for social decision-making. For example, when public schools are evaluated by students’ performance on standardized tests, teachers respond by teaching “to the test”. In turn, the test serves largely as of how well the school can prepare students for the test.We can see this principle—often summarized as “when a measure becomes a target, it ceases to be a good measure”—playing out in the realm of research. Science is a competitive enterprise. There are far more credentialed (授以证书的) scholars and researchers than there are university professorships or comparably prestigious research positions. Once someone acquires a research position, there is additional competition for tenure grant funding, and support and placement for graduate students. Due to this competition for resources, scientists must be evaluated and compared. How do you tell if someone is a good scientist?An oft-used metric is the number of publications one has in peer-reviewed journals, as well as the status of those journals. Metrics like these make it straightforward to compare researchers whose work may otherwise be quite different. Unfortunately, this also makes these numbers susceptible to exploitation.If scientists are motivated to publish often and in high-impact journals, we might expect them to actively try to game the system. And certainly, some do—as seen in recent high-profile cases of scientific fraud(欺诈). If malicious fraud is the prime concern, then perhaps the solution is simply heightened alertness.However, most scientists are, I believe, genuinely interested in learning about the world, and honest. The problem with incentives is that they can shape cultural norms without any intention on the part of individuals.12. Which of the following is TRUE about the general trend in scientific field?A. Scientists are persistently devoted to exploration of reality.B. The research findings fail to achieve the expected effect.C. Hypotheses are modified to highlight the experiments' results.D. The amount of science that does replicate is comforting.13. What doesdeaf earsin the fourth paragraph probably refer to?A. The public.B. The incentive initiators.C. The peer researchers.D. The high-impact journal editors.14. Which of the following does the author probably agree with?A. Good scientists excel in seeking resources and securing research positions.B. Competition for resources inspires researchers to work in a more skeptical way.C. All the credentialed scholars and researchers will not take up university professorships.D. The number of publication reveals how scientists are bitterly exploited.15. According to the author, what might be a remedy for the fundamental problem in scientific research?A. High-impact journals are encouraged to reform the incentives for publication.B. The peer-review process is supposed to scale up inspection of scientific fraud.C. Researchers are motivated to get actively involved in gaming the current system.D. Career incentives for scientists are expected to consider their personal intention.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。

Comedian Caitlin Reilly used the app during quarantine (隔离) to make fun of those annoying coworkers for one of the top liked videos. And singer Curtis Roach made an song for the endless days at home with his song Bored in the House.The second most popular video was an Idaho man named Nathan Apodaca who shot to fame after coolly singing Dreams by Fleetwood Mac, while skateboarding on a highway.But the most liked TikTok video was awarded to Bella Poarch with 45 million followers, who created a simple but interesting video with a few seconds of well-timed head nods and eye rolls.While the app might be designed for youth, Chikumbu said that the growth of TikTok this year has pushed it more into mainstream culture. “You're seeing everyone from the teenager to the college students with their parents and then their grandparents all making videos,” said Chikumbu. “And now TikTok trulytranscendsgenerations, particularly in this year when people had a lot of time to dig in and not only watch, but try.”4.

Makes use of.B. Goes beyond.C. Calls on.D. Takes charge of.CYour house may have an effect on your figure.Experts say the way you design your home could play a role in whether you pack on the pounds or keep them off. You can make your environment work for you instead of against you. Here are some ways to turn your home into part of your diet plan.Open the curtains and turn up the lights. Dark environments are more likely to encourage overeating, for people are often less self­conscious (难为情) when they’re in poorly lit places—and so more likely to eat lots of food. If your home doesn’t have enough window light, get more lamps and flood the place with brightness.Mind the color1 s. Research suggests warm color1 s fuel our appetites. In one study, people who ate meals in a blue room consumed 33 percent less than those in a yellow or red room. Warm color1 s like yellow make food appear more appetizing, while cold color1 s make us feel less hungry. So when it’s time to repaint, go blue.Don’t forget the clock—or the radio. People who eat slowly tend to consume about 70 fewer calories (卡路里) per meal than those who rush through their meals. Begin keeping track of the time, and try to make dinner last at least 30 minutes. And while you’re at it, actually sit down to eat. If you need some help slowing down, turn on relaxing music. It makesyou less likely to rush through a meal.Downsize the dishes. Big serving bowls and plates can easily make us fat. We eat about 22 percent more when using a 12­inch plate instead of a 10­inch plate. When we choose a large spoon over a smaller one, total intake (摄入) jumps by 14 percent. And we’ll pour about 30 percent more liquid into a short, wide glass than a tall, skinny glass.8. The text is especially helpful for those who care about ____________.A. their home comfortsB. their body shapeC. house buyingD.healthy diets9. A home environment in blue can help people ______________.A. digest food betterB. reduce food intakeC. burn more caloriesD. regain their appetites10. What are people advised to do at mealtimes?A. Eat quickly.B. Play fast music.C. Use smaller spoons.D. Turn down the lights.11. What can be a suitable title for the text?A. Is Your House Making You Fat?B. Waysof Serving DinnerC. Effects of Self­ConsciousnessD. Is Your Home Environment Relaxing?DHardware in general,and smartphones in particular,have become a huge environmental and health problem in the Global South's landfill sites(垃圾填埋场).Electronic waste(e-waste) currently takes up 5 percent of all global waste,and it is set to increase rapidly as more of us own more than one smartphone,laptop and power bank They end up in places like Agbogbloshie on theoutskirts of Ghana's capital,Accra. It is the biggest e-waste dump in the world,where 10,000 informal workers walk through tons of abandoned goods as part of an informal recycling process.They risk their health searching for the precious metals that are found in abandoned smartphones.But Agbogbloshie should not exist.The Basel Convention,a 1989 treaty,aims to prevent developed nations from unauthorized dumping of e-waste in less developed countries.The e-waste industry,however,circumventsregulations by exporting e-waste labelled as "secondhand goods' to poor countries like Ghana,knowing full well hat it is heading for a landfill site.A recent report found Agbogbloshie contained some of the most dangerous chemicals.This is not surprising: smartphones contain chemicals like mercury（水银）,lead and even arsenic(砷).Reportedly, one egg from a free-range chicken in Agbogbloshie contained a certainchemical which can cause cancer and damage the immune system at a level that's about 220 times greater than a limit set by the European Food Safety Authority(EFSA).Most worryingly,these poisonous chemicals are free to pollute the broader soil and water system.This should concern us all, since some ofGhana's top exports are cocoa and nuts.Some governments have started to take responsibility for their consumers' waste.For example,Germanyhas started a project that includes a sustainable recycling system at Agbogbloshie,along with a health clinic for workers.However,governments cannot solve the problem alone, as there is an almost limitless consumer demand for hardware,especially when governments' green policies are focused on issues like climate change.Only the manufacturers can fix this.A more economically sustainable and politically possible solution is through encouraging hardware manufacturers to make the repair, reuse and recycling of hardware profitable,or at least cost-neutral12. What can we infer from Paragraph 2?A. Electronic waste requires more landfill sites acrossGhana.B. Electronic waste is too complex to get fully recycleC. Electronic products need to be improved urgentlyD. Electronic pollution is a burning question in Agbogbloshie13. What does the underlined word "circumvents"in Paragraph 3 mean?A. AbolishesB. TightensC. Brings inD. Gets around14. What should be the best concern according to the text?A. The thread of polluted food around the worldB. The damage of chicken’s immune systemC. The lack of diversity inGhana's exportsD. The violation of EFSA's standards15. What does the author think is the best solution to the e-waste problem?A. Manufacturers' developing a sustainable hardware economyB. Governments’ adjusting their green policies about e-waste.C. Reducing customers' demands for electronic productsD. Manufacturers’ urging the government to make effective policies to ensure more profit.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

2021年西安市长安区第一中学高三英语第一次联考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AThe Internet has revolutionized our lives to such an extent (程度) that for most people, the global network has become more than just a tool but rather an important aid in everyday life. More and more people go online as wireless networks have brought the Internet closer and closer: it’s on our mobile phones, in our cars and TV sets, in hospital surgery rooms and in fishing boats that battle the waves of the Atlantic.And this revolution has brought along with it a new way of shopping. Both big and small, e-business websites have flooded the Internet by the hundreds of thousands. Anything you can buy from a brick and mortar store (实体店) you can also buy online: from food and clothes to toys, no matter what you’re looking for, you’re bound to find the right online store with just a few clicks of the mouse. You can use the Internet to find new suppliers, post buying requests or search for products and services.This revolution has affected brick and mortar business owners greatly. And what was their reaction? They’ve opened online stores to go hand in hand with their conventional business.But do the big players have reasons to be afraid? Are we going to start seeing ghostly, deserted Walmarts (沃尔玛) across the country? Probably not in the near future but the day will come when most people will just stop shopping offline anymore. A trip to Walmart wastes time, burns gas.The recent advancements in mobile technology and the introduction of mobile phones with enhanced (提高的) web capabilities have even made some people order their groceries when they get out from work and have them delivered at their doorstep by the time they get home. And as “Time is money”, this practice is lifesaving for people whowork two jobs.Technology will continue to advance and e-business will follow closely in its footsteps. Everything will become easier and less time consuming, leaving us more time to enjoy the things that really matter in life: the ones we love, our friends and hobbies.1. What is Paragraph 1 mainly about?A. The popularity of mobile phones.B. The great influence of the Internet.C. The importance of the Internet.D. The function of the global network.2. In response to the threat of online business, the brick-and-mortar store owners________.A. have stopped their traditional businessB. have started their dislike of the InternetC. have established their own websiteD. have opened their online stores3. What would be the best title for the passage?A. A New Way of Shopping.B. The Internet Revolution.C. What is the Reaction to Online Shopping?D. Is Online Shopping the Future of E-business?BGlobally, people use roofs to dry out food, do their laundry and sleep. In Belfast, where we're based, there's a culture of enjoying looking down on the city from up high, because it's in a valley. But because we were a conflict area for a long time,many people didn't want to live, work or hang out in the city, and our roofs cape has been neglected.Rooftop projects can be as big or as small as you want. They can be used as social or cultural spaces, for green or blue public facilities. But it's not just about commercial opportunities; it can be as simple as an individual turning his/her city balcony into a mini garden or vegetable patch. It's not just about doing it on a rooftop because it's “cool”.It's about giving up the deep-rooted thought that roofs are off limits and embracing their challenges as opportunities. That can make a huge difference. For instance, we're helping turn the rooftop car park of a city central shopping centre into an outdoor space for employees, due to restrictions they now face indoors because of COVID-19.Using rooftops creatively allows us to cope with many of the challenges faced by cities today--be those environmental, social, technological, or cultural. At the moment,we're being forced to rethink how we use public spaces due to COVID-19. With lots of restrictions on enclosed areas, we should be acknowledging rooftops alternatives.For example,Rotterdam recently hosted a play that took place across its rooftops. Each roof lit up and hosted a different part of the drama, while residents sat and watched, listening to the action through headphones. Are there any challenges? Rain is one. Also is health and safety. But there are creative and practical solutions to all the barriers we face. In fact,the challenges are what make rooftops so exciting----because they give you even moreopportunities to be creative and solve problems. It is always a matter of trial and error.4. What can we learn about rooftops in the first two paragraphs?A. People enjoy getting together on rooftops.B. People can use rooftops to their own advantage.C. Rooftops are made good use of by locals in Belfast.D. Rooftops projects were launched for commercial reasons.5. How can rooftops benefit people in their life?A. Rooftops can be adapted to car parks.B. Rooftops help solve environmental problems.C. Rooftops can provide space for work and play.D. People can exchange their thoughts on rooftops.6. What will be possibly mentioned after the last paragraph?A. The new challenges of the future.B. Reasons for building rooftop projects.C. Exciting development of rooftop projects.D. Solutions to the challenges we are facing now.7. What is the author's purpose in writing the text?A. To introduce rooftop projects in Belfast.B. To encourage people to start rooftop projects.C. To analyze the current situation of rooftop projects.D. To offer suggestions on long-term city development.CAccording to the study posted onScienceDirect, gardening just two to three times a week increase the benefits of better well-being as much as possible and lower stress levels.The research explored why residents engaged with gardening and the extent to which they recognized any health benefits from the activity.A questionnaire was handed out electronically within theUK, with 5,766 gardeners and 249 non-gardeners responding. Data was collected on factors including garden typology（类型学）, frequency of gardening and individual awareness of health and well-being."This is the first time the dose response（剂量效应）to gardening has been tested and the evidence from thesurvey strongly suggests that the more frequently you garden, the greaterthe health benefits," said Royal Horticultural Society (RHS) lead author Dr Lauriane Chalmin-Pui. In fact, gardening every day has the same positive impact on well-being than undertaking regular and powerful exercise like cycling or running.When gardening, our brains are pleasantly entertained by nature around us. Gardening takes our attention away from ourselves and our stresses, therefore, it helps restore our minds and reduce unfavorable feelings.Improving health, however, was not the main motive power to garden, but rather the direct pleasure gardening brought to the participants."Gardening is like effortless exercise because it doesn't feel as exhausting and hard as going to the gym, for example, but we canexpendsimilar amounts of energy," Chalmin-Pui added.Most people say they garden for pleasure and enjoyment, so people who like gardening may be easy to be addicted to it. However, this sometimes may become a piece of good news, from the aspect of mental health. "We hope all the millions of new gardeners will be getting their daily gardening and feeling all the better for it. " Chalmin-Pui said in the interview.8. What can be inferred about gardening from the survey?A. Improving health is the aim of the participants.BGardening makes no difference to health.C. Health benefits from frequent gardening.D. Too much gardening always does harm to health.9. What does the underlined word "expend" mean in paragraph 7?A. Consume.B. Make use of.C. Increase.D. Save.10. Why do so many participantslike gardening?A. It isn't exhausting.B. It is good for health.C. It brings pleasure.D. It is like going to the gym.11. What is Chalmin-Pui's attitude to the new gardeners' gardening?A. Carefree.B. SupportiveC. Tolerant.D. Indifferent.DIt’s easy to do easy things, but they don’t carry the challenges and rewards of doing something difficult. 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 theInternational 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.12. 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 boring13. 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.14. Which of the following can best describe Scott?A. Kind and thoughtful.B. Curious and humorous.C. Easygoing and sociable.D. Hardworking and determined.15. 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 rewarding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。

He teaches in the area where having electricity is something of a luxury and students have no access to mobile apps or computers, which became a problem when Guatemalan government had to choosedistance education for students at home because of COVID-19 inmid-March.Gerardo Ixcoy felt that he had to teach those children living far from the digital world. After all, education is a universal right. But what was the solution?Gerardo bought himself a secondhand tricycle with his savings. Once he had the tricycle, the next step was to change it into a classroom on wheels. He put a roof with a solar panel（太阳能电池板）on it, along with a screen to avoid the spread of COVID-19. He fixed a whiteboard on it so he could explain to the students the basics of primary education：math, the local language and the national language Spanish.The purpose of the solar panelis to provide constant power for a small loudspeaker so he can teach from a distance. It's a matter of respecting the healthy distance required to be safe from the virus.

The children he serves say that, although he visits them for only a few hours a week, they look forward to it. They appreciate his visit because they know he has limited time he can devote to them. They must take advantage of it to learn.4. What happened to Gerardo Ixcoy's students because of COVID-19?A. They chose to have classes in groups.B. They had to stop all the classes.C.

Education is the key to success.CWe asked four people who watched an online talk on technology and communication by Sherry Turkle for their opinions.Fred:The talk certainly gave me plenty of food for thought about how technology is changing our behaviour. People are constantly multitasking, whether it be emailing during meetings or texting in the checkout queue. It’s as if we can’t bear to miss out on what our online friends are up to, so we juggle the real and online world. My greatest concern is that we don’t give our brains a chance to switch off. It’sthese precious momentswhen we actually process information that helps us make important decisions.Jeremy:It was a fascinating talk and the speaker really hit the nail on the head with a couple of things. Take parental influence, for instance. How can we expect teenagers not to text while doing their homework when they witness their parents posting on social media while cooking the evening meal or waiting at a red light?Kath:So much of what the speaker said rang true. I honestly believe there’s a danger that the more connected we are, the more isolated we feel. I don’t think this is such an issue for my generation who’ve lived without technology for so long. We know how to be alone. But the under 20s are another kettle of fish. They’re so busy communicating that they never experience the feeling of solitude and run the risk of not learning how to enjoy their own company.Carl:I’m not sure to what extent I agree that people are more alone, but the way we communicate has certainly evolved. The speaker makes a good point about how we’re getting used to talking with machines like Siri or robots, which are totally lack of experience of human life. But despite such limitations, we seem to be expecting more from technology and less from each other.8. What does the underlined phrase “these precious moments” in paragraph 2 refer to?A. When our brains are free.B. When we emailing during meeting.C. When we texting in the checkout queue.D. When we juggle the real and online world.9. What suggestion may Jeremy give to the parents?A. Accompany their children when they are doing homework.B. Prevent their children using phone while doing homework.C. Set a good example for their children on using phone properly.D. Stop posting on social media in face of their children.10. What does Kath worry about the under 20s generation?A. They communicate more with others.B. They use more technology.C. It’s difficult for them to find companies.D. They don’t know how to be alone.11. What is Carl’s attitude towards the use of technology in communication?A. Favorable.B. Intolerant.C. Doubtful.D. Indifferent.DIf you’re looking for a reason to care about tree loss, this summer’s record-breaking heat waves might be it. Trees can lower summer daytime temperatures by as much as 10 degrees Fahrenheit, according to arecent study.But tree cover in US cities is shrinking (缩减). A study published last year by the US Forest Service found that we lost 36 million trees annually from urban and rural communities over a five-year period. “If we continue on this path, cities will become warmer, more polluted and generally unhealthier for inhabitants,” said David Nowak, a senior US Forest Service scientist and co-author of the study. Nowak says there are many reasons why our tree cover is declining, including hurricanes, tornadoes, fires, insects and disease. But the one reason for tree loss that humans can control is sensible development.Nowak says there is a downside to trees too, such as pollen allergy (花粉过敏) or large tailing branches in storms, and people don’t like sweeping leaves. But, he says, there are ways cities and counties can manage trees to help communities thrive (繁荣). Urban forests especially need our help to replace fallen trees. Unlike rural areas, it is very difficult for trees to repopulate themselves in a city environment with so much pavement and asphalt (沥青). “A lot of our native trees can’t actually find a place to drop a seed so they can regenerate,” explains Greg Levine, co-executivedirector of Trees Atlanta. “That’s why the community has to go in and actually plant a tree because the areas just aren’t natural anymore.”Nowak says the first step is caring for the trees on your own property (财产). “We think we pay for our house, and sowe must maintain it. But because we don’t pay for nature, we don’t need to. And that’s not necessarily true.”12. Why does the author mention “trees can lower summer daytime temperatures”?A. To tell the temperatures in summer are high.B. To explain the reason of tree loss.C. To tell trees are helpful.D. To introduce the topic.13. How can humans control tree loss according to Nowak?A. Develop cities in reasonable ways.B. Prevent fires form damaging trees.C. Improve climate to let trees grow.D. Decrease insects in cities.14. Why do forests in cities need our help?A. Because trees don’t grow in a city environment.B. Because native trees don’t drop seeds any more.C. Because trees in urban areas can’t regenerate naturally.D. Because humans want to plant more trees.15. What is the purpose of this passage?A. Describe the importance of trees in cities.B. Appeal people to protect trees in their surroundings.C. Ask people to plant trees with the author.D. Show the number of trees in theUSis declining.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。
