2021年成都七中高三英语期末考试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AI once taught in a small private school. Each morning at nine o’clock all the students, ranging in age from three to seven years old, gathered in the Great Room for a warm-up in preparation for the day.One morning the headmistress made an announcement to all the children gathered,“Today we begin a great experiment of the mind.” She held up two ivy(常春藤) plants, each potted in an identical container. She continued, “Do they look the same?”All the children nodded. So did I, for, in this way, I was alsoa child.“We will give the plants the same amount of light, the same amount of water, but not the same amount of attention,” She said. “Together we are going to see what will happen when we put one plant in the kitchen away from our attention and the other plant right here in this room. Each day for the next month, we shall sing to our plant in the Great Room and tell it how much we love it, and how beautiful it is. We will use our good minds to think good thoughts about it.”Four weeks later my eyes were as wide and disbelieving as the children’s. The kitchen plant was leggy and sick-looking, and it hadn’t grown at all. But the Great Room plant, which had been sung to and surrounded by positive thoughts and words, had increased threefold in size with dark leaves that were filled with energy.In order to prove the experiment, the kitchen ivy was brought to the Great Room to join the other ivy. Within three weeks, the second plant had caught up with the first ivy. Within four weeks, they could not be distinguished, one from the other.I took this lesson to heart and made it my own.1. Why did the headmistress do the experiment?A. She wanted to teach me a lesson.B. She expected the students to learn to grow plants.C. She meant to prove the impact of good minds on growth.D. She intended to show students how to save a sick-looking plant.2. What happened to the ivy in the kitchen at last?A. It stopped growing and died.B. It was leggy and sick with dark leaves.C. It looked almost the same as the other one.D. It grew better than the one in the Great Room.3. What can be a suitable title for the passage?A. Life Means GrowthB. Things Grow with LoveC. Equality Makes a DifferenceD. Positive Thoughts Really CountBThe first patient who died on my watch was an older man with a faulty heart. We tried to slow it down with treatment, but it suddenly stopped beating completely. Later, whenever I would have a case like that one, I found myself second-guessing my clinical management. However, it turns out that thinking twice may actually cause more harm than good.In a working paper, Emory University researchers found that when doctors delivering a baby have a bad result, they are more likely to switch to a different delivery method with the next patient, often unnecessarily and sometimes with worse results.Because doctors make so many decisions that have serious consequences, thefalloutfrom second-guessing appears especially large for us. A 2006 study found that if a patient had a bleed after being prescribed (开药) warfarin, the physician was about 20% less likely to prescribe later patients the blood thinner that prevents strokes (中风). However, if a patient was not on warfarin and had a stroke physicians were still no more likely to prescribe warfarin to their other patients.These findings highlight interesting behavioral patterns in doctors. In the blood-thinner study, doctors were more affected by the act of doing harm (prescribing a blood thinner that ended up hurting doctors were more affected by the act of doing harm(prescribing a blood thinner that ended up hurting a patient) and less affected by letting harm happen (not prescribing a blood thinner and the patient having a stroke). Yet a stroke is often more permanent and damaging than a bleed.But this phenomenon is not unique to medicine. ''Overreaction to Fearsome Risks'' holds true for broader society.For instance, sensational headlines about shark attacks on humans in Florida in 2001 caused a panic and led the state to prohibit shark-feeding expeditions. Yet shark attacks had actually fallen that year and, according to thestudy, such a change was probably unnecessary given the extremely small risk of such an attack happening.Humans are likely to be influenced by emotional and often irrational (不理性的) thinking when processing information, bad events and mistakes. As much as we don't want to cause an unfortunate event to happen again, we need to be aware that a worst situation that can be imagined doesn't necessarily mean we did anything wrong. When we overthink, we fail to rely on thinking based on what we know or have experienced. Instead, we may involuntarily overanalyze and come to the wrong conclusion.I have treated dozens of patients who presented with the same illnesses as my first patient, who died more than a year ago. Instead of second-guessing myself, I trusted my clinical instinct (本能) and stayed the course. Every one of those patients survived. You should trust your instinct in your life, too.4. The first two paragraphs suggest that________.A. bad medical outcomes affect doctorsB delivering babies can be difficult workC. some doctors are not very experiencedD. doctors sometimes make silly mistakes5. In the blood-thinner study, doctors________.A. tend to prescribe less effective medicineB. are more concerned about the patients' safetyC. become less confident in writing a prescriptionD. believe a stroke is more treatable than a bleeding6. What does the underlined word ''fallout'' in Paragraph 3 probably mean?A. ResultB. BenefitC. DifferenceD. Absence7. The author will probably agree that________.A. we should not doubt our own decisionsB. our experience will pave way for our futureC. humans are emotional and irrational on the wholeD. instincts don't necessarily lead to wrong directionsCKenyan mother Beth Mwende heard her sleeping child cry out, but did not worry after the three-year-old quickly quietened down. The next morning, however, she found her daughter, Mercy, nearly unconscious with two bite marks in the neck. “I didn’t know that it was a snake,” Mwende said.Although snakebites are common in her hometown, antivenom medication is difficult to get. Mwende lives about 160 kilometers east of Nairobi, Kenya’s capital. So she took her daughter to a traditional healer. He placed stones over the bites. Mercy died within hours. She was one of about 700 Kenyans killed by snakebites each year, notes a report in the scientific publicationToxicon.The Kenya Snakebite Research and Intervention Center (KSRIC) is working to change that. The KSRIC hopes to have East Africa’s first antivenom medication on the market within five years. It estimates the cost will be about 30 percent of an imported product, which often sells for about US $ 30.More than 70, 000 people are bitten in East Africa each year. Climate change and deforestation are worsening the problem as snakes get pushed out of natural surroundings into populated areas.Nearly 100 snakes live at the research center in a forest near Nairobi. Researchers take venom from snakes and study it before injecting small amounts into other animals, such as sheep. The animals then create antibodies that can be made into antivenom.“Up to now, no one has made any kind of antivenom in Kenya,’’ said Geoffrey Maranga Kepha, a senior snake handler.Two effective antivenoms are available in Kenya, from India and Mexico, the center says.The center is teaching communities that using antivenom immediately after receiving a snakebite can save lives, said head researcher George Adinoh.“After seeing how people died in Kenya from snakebites I decided to devote my life to coming up with a rescue measure that will help or prevent people from dying from snakebites,” snake handler Kepha added.8. How does the author introduce the topic of the text?A. By telling a story.B. By listing figures.C. By referririg to documents.D. By making a comparison.9. Why did Mwende take her daughter to a traditional healer?A. She couldn’t afford any modern treatment.B. She lived where antivenom medication is not available.C. The traditional way is very effective to treat snakebites.D. She believed a traditional healer could cure her daughter.10. What is causing more snakebites to happen in East Africa?A. Lack of antivenom medication.B. Environmental damage and climate change.C. People’s low awareness of the danger of snakes.D. People’s pursuit of traditional cures for snakebites.11. What do we know about antivenom in Kenya from the text?A. Itis taken from antibodies of sheep.B. There is only one effective antivenom available.C. KSRIC is trying to develop a local antivenom now.D. People refuse to use antivenom after being bitten by snakes.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年成都七中高三英语上学期期末试卷及参考答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AI started working with my hands at a young age. The youngest of five brothers, I took on the role as a “maintenance (维修) man” at an early age for our family’s small grocery store. Often my dad wouldn’t give me a clear idea of how something shouldbe done, so I just had to figure it out by researching or through trial and error.Fast forward to 2016 and those problem-solving skills would become the focus of Tippecanoe High School’s Homebuilding class. I knew I wanted to teach the students skills that went beyond just being able to hammer nails or cut pieces of two-by-fours. The problem was that we didn’t have the resources at the time to do much else. The idea of attracting some type of funding seemed very important. Designing, building and selling a tiny house on wheels seemed like the perfect project to accomplishthe task. I reached out to a number of local businesses and most of them responded with the greatest support for what x k w we were doing.This year we added a new element to the program. Through one of our partners, we were able to connect with the nonprofit Veteran’s Ananda Incorporated. Students in the Homebuilding class are leading the design and production of micro houses to be donated to this organization. The new partnership gives the students another focus to consider when designing and building the houses.There has been no shortage of students since our first year. Three years ago we had 41 students, the next 191, and this year it was limited to just over 160 students so we could have a safe and manageable classroom environment. The number of girls taking the class has risen steadily over the last few years as well. This class offers something for everyone and the skills are universal.1. How can we describe the young author?A. He opened a small grocery store.B. He did a lot of research in the lab.C. He enjoyed doing hands-on activities.D. He learnt about maintenance from his father.2. What do the underlined words “the task” in paragraph 2 refer to?A. Getting some financial support.B. Selling a tiny house on wheels.C. Reaching out to many local businesses.D. Offering the students some problem-solving skills.3. What can be inferred about the Homebuilding class from the last paragraph?A. Its size needs increasing.B. Itis popular with the students.C. It has caused some safety concerns.D. Its classroom environment is hard to manage.BThe mass death of flying foxes in extreme heat in North Queensland last month underlines the importance ofUniversityofQueenslandwildliferesearch released today.The UQ research sheds light on how various species have responded to major climate events.A study led by UQ School of Earth and Environmental Science researcher Dr Sean Maxwell has spent more than 70 years quantifying the responses of various species.“The growing frequency and intensity of extreme weather events such as cyclones, droughts and floods is causing unpredictable and immediate changes to ecosystems and blocking existing management efforts,” Dr Maxwell said.“Some of the negative responses we found were quite concerning, including more than 100 cases of dramatic population declines and 31 cases of local population extinction following an extreme event.”"Populations of critically endangered bird species inHawaii, such as the palia, have been annihilated due to drought, leaving none of its kind, and populations of lizard species have been wiped out due to cyclones in theBahamas."Cyclones were the most common extreme event for birds, fish, plants and reptiles, while mammals and amphibians were most responsive to drought events, with drought leading to 12 cases of major population decline in mammals.Drought also led to 13 cases of breeding declines in bird populations and 12 cases of changes in the composition of invertebrate communities.UQ Centre for Biodiversity and Conservation Science director Professor James Watson said the detailed information would help inform ecosystem management.“The research clearly shows species will respond, often negatively, to extreme events,” Professor Watson said.“As climate change continues to ensure extreme climate and weather events are more and more common,we now need to act to ensure species have the best chance to survive.Wherever possible, high quality and intact habitat areas should be retained, as these are the places where species are most resilient(易恢复的) to increasingexposure to extreme events.”4. How was the UQ researchconducted?A. By observing extreme weather events.B. By protecting the endangered species.C. By recording reactions of animals to extreme climate.D. By analyzing the reason whymass animal death happened.5. What does the underlined word “annihilated” in paragraph 4 probably mean?A. destroyedB. defeatedC. decreasedD. disappeared6. Which of the following sentences is true about extreme weather events?A. Drought caused 13 cases of distinctionin bird populations.B. Drought caused 12 cases of population decline in mammals.C. Birds and mammals are most responsive to cyclones.D. Cyclones wiped out populations of lizard.7. What can we infer from Professor Watson’s words?A. Animals often show negative responses to extreme events.B. The existing management ways for wildlife protection are limited.C. Different methods should be adopted to ensure the survival of different species.D. Complete and undamaged habitats are of great importance to species’ survival.CMost children who have suffered from ADHD still have it as teens. During teen years, especially as the hormonal changes of teenagers are going on and the demands of school and extra-curricular activities are increasing, ADHD may get worse.Because of problems with getting unfocused and poor concentration, many teens with ADHD have problems in school. Grades may fall, especially if the teen is not getting ADHD treatment. It’s not uncommon for teens with ADHD to forget their homework, lose textbooks, and become bored with their daily class work. Teens may become inattentive or extremely attentive, not waiting for their turn before blurting out answers. They may cut in on their teacher and classmates. Teens with ADHD may also befidgetyand find it hard to sit still in class.Often, teens with ADHD are so busy focusing on other things that they forget about the task at hand. This can be seen especially with homework and athletic skills and in relationships with their schoolmates. This lack ofattention to what they’re doing often leads to bad grades on tests and being passed over for sports teams, after-school activities, and learning teams. Kids with ADHD can be targets for bullying, too. But, not all children with ADHD have trouble getting along with others. If your child does, you can take measures to help improve their social skills and relationships.ADHD affects all parts of a teenager’s life. As a parent you should discover your teen’s troubles as early as possible. The earlier your child’s troubles are discovered, the more successful the following steps can be.8. What does the author plan to do in paragraph 1?A. To list the types of ADHD.B. To introduce the main topic.C. To show the author’s opinion.D. To explain the causes of ADHD.9. What does the underlined word “fidgety” probably mean in paragraph 2?A. Clever.B. Noisy.C. Restless.D. Lazy.10. What is the text mainly about?A. Ways to deal with ADHD.B. Effects of ADHD on teens.C. Teens’ school performances.D. Demands of school work.11. What may the following paragraph talk about?A. How parents can help a teen with ADHD.B. The importance of healthy peer relationships.C. How many children are suffering from ADHD. D. Different opinions about treating ADHD in teens.DI have a memory of being about five years old, picking up a beautiful grilled(烧烤的）cheese sandwich made for me by my hard —working mother and turning it over to see that theother side was burned. Suddenly what I thought was the perfect sandwich was not so perfect. Mom had tried to hide that fact from me. There was no question; I ate it anyway without complaining. However, that moment has stuck in my mind for many years. Now, at the age of 43 as a mother of two children and as a biology professor where I am routinely the "academic mother" of hundreds of students every year,I find that I believe inThe Grilled Cheese Principle.Here is what I mean Making a grilled cheese sandwich is easy right? But when I think of how many burned grilled cheese sandwiches I have eaten, or I have made myself, I realize that most of the grilled cheese sandwiches I have known have had at least one burned side. The thing is that although it is a ly easy thing to make, I can also easily lose focus, and before long the sandwich is burned. For my mother, the first side was usually perfect and the second side got burned due to her being distracted. For me,I have tended to burn the first side,but then I more carefullymonitor the second side.Either way,the grilled cheese sandwich suffers because it has not been given the attention it deservesSo, I have learned that even the simplest task deserves my full attention. When I am multi-tasking, I am doing none of the tasks well. And when I allow myself to be distracted, I am not in the present moment — not paying attention to the small details of living or enjoying the processSo now, I believe the best way to make a perfect grilled cheese sandwich is to make only one at a time and give it my full attention.12. How did the writer react to the sandwich with burned side?A. She ate it with some complaintsB. She showed no interest.C. She thought it was still perfectD. She was deeply impressed with it13. What doesThe Grilled Cheese Principlemean?A. Even simple things deserve full attentionB. Losing focus makes the sandwich burnedC. Self-made sandwiches are always burnedD. we should make only one sandwich at a time14. Which of the following can we infer from the passage?A. Everything cannot be done well without full attentionB. Moms always like to lie to kids when they have done something wrongC. We can lose focus more easily when we do easy things.D. Multi-tasking can be an obstacle to the achievement of tasks.15. What does the writer mainly want to tell us?A. Nothing is perfectB. Learn to appreciate the burned sandwichesC. Devote yourself to one thing at a time.D. Never do multi-tasks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届成都七中高三英语上学期期末考试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AIf you are sending a text message watching TV or listening to the radio, you may stop and give this your full attention. Multitasking shrinks (使.....萎缩)the brain? research suggests.A study found that men and womenwho frequently used several types of technology at the same time had less grey matter in a key part of the brain. University of Sussex researchers said, " Using mobile phones, laptops and other media devicessimultaneouslycould be changing the structure of our brains."Worryingly, the part of the brain that shrinks is involved in processing emotion. The finding follows research which has linked multitasking with a shortened attention span, depression , anxiety and lower grades at school.The researchers began by asking 75 healthy men and women how often they divided their attention between different types of technology. This could mean sending a text message while listening to music and checking e-mail, or speaking on the phone while watching TV and surfing the Internet. The volunteers were then given brain scans which showed they had less grey matter in a region called the anterior cingu-late cortex (ACC)(前扣带皮层).Scientists have proved that brain structure can be changed on exposure to fresh environments and experience.Other studies have shown that training—such as learning to play magic tricks or taxi drivers' learning the map of London―can increase grey matter densities (密度)in certain parts.Experts have also warned of the harmful impact technology can have on our memory and attention span. The University of California team conducted a survey of more than 18,000 people aged between 18 and 99，and found 20%had problems with memory. Researchers were shocked greatly by the 14 % of 18 to 39-year-old people who also worried about their memories.Multitasking may shorten attention span, making it harder to focus and form memories, the researchers said, adding that youngsters may be particularly affected by stress.1. The underlined word " simultaneously" in Paragraph 2 means "________，"A. on one's ownB. at no timeC. at the same timeD. by accident2. All of the following are possible effects of multitasking EXCEPT________ .A. saving timeB. a shortened attention spanC. lower grades at schoolD. depression and anxiety3. Which ofthe following can be the best title of this passage?A. Media multitasking is becoming more popularB. Multitasking shrinks the brainC. Multitasking may shorten attention spanD. People are worried about their memories.BOn March 18, 34-year-old Lance Karlson was walking on the beach and looking for somewhere toswim in Geographe Bay when he saw what he thought was a stingray (黄貂鱼) leap from the water.Realizing the creature was, in fact, an octopus (章鱼), he started filming it — just in time for the angry octopus to launch itself at him. He immediately felt a sharp pain across his left arm, followed by a second strike across his neck and upper back. His goggles (护目镜) fogged and the water around him turned dark with what he thought might have been octopus ink as he struggled back toward the shore."I was confused — it was more of a shock than a fright," said Karlson, "I might have hit on its home." Within a minute, a perfect imprint of an octopus tentacle (触手) appeared on Karlson's neck and back.A former volunteer lifeguard, Karlson rushed back to his hotelroom to find something acidic to put on the wound. All his family could grab was Coca-Cola, which his wife poured over his back and the pain disappeared."The pain went away and more than anything since then, it's been more the physical hit that was painful.... The imprint on my neck is more from the physical hit, and I guess it makes complete sense when you look at the video I took," he said.Karlson said he'd never seen an octopus that close before and watched Netflix documentary "My Octopus Teacher" after the incident to learn more about the species."They are beautiful creatures and I really hope this promotes more interest in octopuses as opposed to fear of them. I think this is a fascinating creature with clearly some very strong emotions just like we do as humans," he added.4. When did the octopus attack Karlson?A. When he was swimming in the bay.B. When he was shooting the octopus.C. When he was looking for some fish.D. When he was fighting against the octopus.5. What plays an essential role in reducing Karlson's pain?A. The lifeguard's timely help.B. Karson's wife's quick action.C. The family members' efforts.D. Karlson’s knowledge of first aid.6. What does Karlson learn from his experience?A. The octopus is dangerous.B. People should get away from the octopus.C. People need know more about the octopus.D. The physical hit from the octopus is painful.7. Which of the following might be the best title?A. Pain from Strong AttackB. First Aid for Octopus' StrikeC. Face to Face with Angry OctopusD. Under Sea with Dangerous CreatureCIf you ever find yourself trapped in the wilderness without food, you'llhave to figure out how to feed yourself. Many plants in the wild areedible, but many are also poisonous. So it is necessary to learn how to determine whether the plants you find can be eaten safely.Avoid using this method without careful planning. Some plants can be deadly, and even if you follow these guidelines perfectly, there is always a chance that a plant will make you seriously ill. Prepare yourself for wilderness outings by learning about the local plants, and carry a guidebook to help you identify plants. Even if you are unprepared and cannot find food you know to be safe, remember that, depending on your activity level, the human body can go for days without food, and you’re better off being hungry than being poisoned.Testing the plant in your mouth is dangerous, so go forward very slowly and carefully. First, hold a small portion of the prepared plant part against your lip for 3 minutes. Do not put the plant in your mouth. If you notice any burning, tingling (刺痛), or other reactions, discontinue testing. Second, place another small portion of the plant part on your tongue. Hold the plant on your tongue without chewing for 15 minutes. Discontinue testing ifyou notice any reaction. Third, chew the plant and holdit in your mouth for 15 minutes. Chew the plant well, and do not swallow. Discontinue testing if you notice any reaction. Fourth, swallow the small portion of the plant. Wait 8 hours. Do not eat or drink anything during this period except purified water. If you feel sick, immediately throw up what you eat and drink plenty of water. If activated charcoal (活性炭) is available, take that with the water.8. What’s the meaning of the underlined world “edible” in paragraph 1?A. Suitable for using as food.B. Widely spread.C. Existing in large quantities.D. Not widely known.9. What can we know from paragraph 2?A. Planning is unnecessary when using the method.B. Not all plants in the wild can serve as food generally.C. Suffering hunger can be more dangerous than testing plants.D. Following the method perfectly can ensure safety.10. Which is the correct order of testing plants in the mouth?① wait and see ② chew it in the mouth③ put it on the tongue④ put it against lips ⑤ swallow itA. ③④②①⑤B. ④③②①⑤C. ③④②⑤①D.④③②⑤①11. Where might the passage come from?A. A student’s diary.B. A science report.C. A guide book for camping.D. A doctor’ s notebook.DThe United Nations Educational, Scientific and Cultural Organization (UNESCO) included on December 17, 2020 China's Tai Chi on the RepresentativeList of the Intangible（无形的）Cultural Heritage of Humanity. The decision was announced during the online meeting of the UNESCO Intergovernmental Committee for the Safeguarding of the Intangible Cultural Heritage held from December 14 to19 inKingston, capital ofJamaica.“Born in the mid-17th century in a small village named Chenjiagou located in Central China's Henan province, Tai Chi is not only a kind of traditional Wushu integrated with slow movements and deep breathing, but is also deeply rooted in many areas of Chinese culture, such as medicine and philosophy,”Zhu Xianghua says, who is the son of the famous Tai Chi master Zhu Tiancai.Although it has spread to more than 150 countries and regions, attracting more than 100 million people to practice, the idea that Tai Chi is for the elderly has stopped many young people practicing the ancient Wushu. They think of it as a slow exercise, which is specially made and better suited for their grandparents. Instead, many young people are turning to the Indian practice of yoga（瑜伽）to relieve stress, which was placed on the UNESCO's List in 2019.In order to promote Tai Chi, joint efforts have been made from individuals and the Chinese government in the last decades. Xi'an Jiaotong University requires students to learn Tai Chi. Wang Yunbing, a professor in the university's sports center, stressed that Tai Chi is not only good physical exercise-researchers from the American College of Rheumatology find that it can help manage several diseases but is also conned ted to ancient Chinese eivilization. Since 2014, the World Tai Chi Championships have been held every two years by the International Wushu Federation. It provides a platform for communication and learning between the Tai Chi masters and Tai Chi lovers around the globe. In January 2020, Tai Chi became an official event in the 2026 Dakar Youth Olympic Games.12. What does Zhu Xianghua say about Tai Chi in paragraph 2?A. It originated from fast Kung Fu action.B. It was born around the 1750s in a village.C. It is related to other cultural fields ofChina.D. It integrates Chinese medicine and western philosophy.13. Why do some young people choose to practice yoga instead of Tai Chi?A. They think it easier to practice yoga to keep fit.B. The elderly stop young people practicing Tai Chi.C. They consider Tai Chi is custom-built for old people.D. Yoga was included in the world culture earlier than Tai Chi.14. What is the main purpose of the last paragraph?A. To promote contemporary Chinese civilization.B. To show many efforts made to popularize Tai Chi.C. To stress the importance of Chinese Tai Chi masters.D.

Knightscope says the goal is to reduce crime by half in areas the robots guard.William Santana Li is the chief executive officer of Knightscope. He says，"These robot security guards will change the world. Our planet has more than seven billion people on it. It's going to quickly get to nine billion people. The security equipmentthat we have globally is just not going to develop that fast. The company's Autonomous Data Machines can become the eyes and ears of law enforcement（执法）.""You want them to be machines plus humans. Let. the machines do the heavy and sometimes dangerous work and let the humans do the strategic decision-making work，so it's always working all together."The machines do not carry weapons but they have day and night video cameras which are able to turn 360 degrees and can also sense chemical and biological weapons.Some people may become concerned about their privacy, especially in connection with the video recordings. Some people may worry that such recordings will appear on the Internet. Eugene Volokh, a law professor at the UCLA School of Law, says the machines have to be used in the right way and it will be interesting to see how state laws deal with this kind of video.William Santana Li says there is a long waiting list for the robots in theUS. Workers in the company are working overtime to meet the demands of the market. At least 25 other countries are also interested in these robot security guards.1.

Security Robots Could Help Cut CrimeBBabies who frequently communicate with their caregivers using eye contact and vocalisations(发声)at the age of one are more likely to develop greater languages skills by the time they reachtwo,according to new research.In the study, researchers looked at 11-and 12-month-od babies' vocalisations. gestures and gaze behaviours ,and at how their caregivers responded to them.To measure he interactions ,the researchers videoed infants(婴儿)and caregiver at home,and asked them to play as usual.They took those recordings back to the universityThe scientists then used statistical models to find that the best predictor of vocabulary at 24 months was when infants were seen to use vocalsatioms while looking at their caregiver's face when they were about a year old.The benefits were even greater when these interactions were followed by responses from the caregiver.The statistics showed that at 19 months,children had an average of about 100 words.Those who exhibited the beneficial interactive behaviour earlier in life were seen to have an average of about 30 extra words."The message of this paper is thatitis the result of a joint effort; noticing what your child is attending to and talking to them about it will support their language development." said McGillion, a co-author of the work."The joy of this message is that that can happen in any context... across any part of your day.It's not something that requires special equipment or even lots of time.I can happen when you're doing the laundry,for example—when you're taking out the socks, you can talk about socks...in the park, in the car, at mealtimes,at bathtimes.This finding can be used in any context,"added McGillion."This is a developmental snapshot in the first year of life, but children are constantly growing and changing and so are their behaviours. It would be interesting to look at these sorts of behaviours again as children progress through the second year of life to see what's happening there,"said Donnellan,the lead author on the study.4. How did the researchers get the findings?A. By interacting with babies.B. By asking babies to vocalize.C. By analyzing relevant recordings.D. By referring to the previous statistics.5.

What might further studies be on?A. Children's academic progress.B. Children's growing environment.C. Children's potential physical development.D. Children's behaviours across more age ranges.CScientists at the Massachusetts Institute of Technology (麻省理工学院) have turned spider webs into music——creating an strange soundtrack that could help them better understand how the spiders output their complex creations and even how they communicate.The MIT team worked with Berlin-based artist Tomas Saraceno to take 2D (two-dimensional) laser (激光) scans of a spider web, which were linked together and made into a mathematical model that could recreate the web in 3Din VR (virtual reality). They also worked with MIT’s music department to create the virtual instrument.“Even though the web looks really random (随机)，there actually are a lot of inside structures and you can visualize (可视化) them and you can look at them, but it’s really hard to grasp for the human imagination or human brain to understand all these structural details,” said MIT engineering professor Markus Buehler, whopresented the work on Monday at a virtual meeting of the American Chemical Society.Listening to the music while moving through the VR spider web lets you see and hear these structural changes and gives a better idea of how spiders see the world, he told CNN. “Spiders use vibrations (振动) as a way to locate themselves, to communicate with other spiders and so the idea of thinking really like a spider would experience the world was something that was very important to us as spider material scientists,” Buehler said.Spiders are able to build their webs without shelves or supports, so having a better idea of how they work could lead to the development of advanced new 3D printing techniques. “The reason why I did that is I wanted to be able to get information really from the spider world, which is very weird and mysterious,” Buehler explained. In addition to the scientific value, Buehler said the webs are musically interesting and that you can hear the sounds the spider creates during construction. “It’s unusual and eerie and scary, but finally beautiful.” he described.8. What have MIT scientists done according to the passage?A. They have translated spider webs into sounds.B. They have made a mathematical model to produce webs.C. They have created a soundtrack to catch spiders.D. They have known how spiders communicate.9. What can we know about spider webs from paragraph 3?A. Their structures are beautiful and clear.B. Professor Markus Buehler knows them well.C. The American Chemical Society presents the result.D. They are complex for people to figure it out.10. In which field will the study be helpful?A. virtual realityB. printingC. paintingD. film-making11. What is the main idea of the passage?A. It tells us that the music created by spiders is scary.B. It shows how the researchers carry out the experiment.C. It presents a new and creative way to study spiders.D. It explains why scientists did the experiment.DThe annual 3-to-4-millimeter rise in sea levels is expected to impact many coastal communities in the comingdecades. However, few are as defenceless as the Republic of theMaldives, a collection of more than a thousand picturesque islands in theIndian Ocean. NASA researchers believe that parts of what is “arguably the lowest-lying country in the world” will become uninhabitable by 2050, due to wave-driven flooding and limited freshwater. To fight the unavoidable, the government recently revealed plans for the world's first 'true' floating island city.The aptly-named Maldives Floating City (MFC) is the brainchild of Dutch Docklands, a global leader in floating infrastructure (基建). According to the March 13, 2021, announcement, the new city will be constructed on a 200-hectare lagoon (环礁湖) located just 10 minutes by boat from the Maldivian capital, Male. It will initially consist of a thousand waterfront residences, arranged in a series of honeycomb-like maze rows. The developers plan to add hotels, restaurants, shops, and even a school and a hospital in the near future. The floating structures. will be attached to the surrounding islands, which will form a base and provide protection from high tides.Maldive officials aim to make MFC as self-sufficient as possible. Freshwater storage will provide drinking water for residents, while floating solar blankets and agriculture fields will take care of their energy and food needs.“ThisMaldivesFloatingCitydoes not require any land rehabilitation, therefore has a minimal impact on the coral reefs,” explains Mohamed Nasheed, Speaker of Parliament. “What's more, giant, new reefs will be grown to act as water breakers. In theMaldives,we cannot stop the waves, but we can rise with them.”Construction of the revolutionary city is expected to begin in 2022 and be completed in phases over the next five years. If successful, it will provide a blueprint for other countries facing a similar situation.12. Why doesMaldivesdecide to build MFC?A. It is the lowest-lying country.B. It will be flooded soon.C. It is running out of fresh water.D. It will be unsuitable for living.13. What is Paragraph 2 mainly about?A. The prospect of MFC.B. The developers of the plan.C. The location of the residences.D. The barriers to the construction.14. What can we infer from the underlined words?A. MFC will keep waves away.B. MFC will make use of waves.C. MFC will adjust to the waves.D. MFC will work as water breakers.15. What's the writing purpose of this passage?A. To introduce a construction program.B. To appeal to people to protect nature.C. To seek international help forMaldives.D. To report the achievement of a city plan,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。

Crowds celebrate with viewing parties,flockingto the most popular locations to take photos and have picnics underneath the branches.But this year, cherry blossom season has come and gone in the blink of an eye, in one of the earliest blooms on record. Scientists warn it’s a symptom of the larger climate crisis threatening ecosystems everywhere.Yasuyuki Aono, a researcher atOsakaPrefectureUniversity, has gathered records fromKyotoback to 812 AD from historical documents and diaries. In the central city ofKyoto, cherry blossoms peaked on March 26, the earliest in more than 1,200 years, Aono said. And in the capitalTokyo, cherry blossoms reached full bloom on March 22, the second-earliest date on record.The peak bloom dates shift every year, depending on numerous factors including weather and rainfall, but have shown a general trend of moving earlier and earlier. InKyoto, the peak date stayed around mid-April for centuries, but began moving into early April during the 1800s. The date has only dipped into late March a handfulof times in recorded history.“Sakura blooms are very temperature sensitive,” said Aono. “Flowering and full bloom could be earlier or later depending on the temperature alone,” he said. “The temperature was low in the 1820s, but it has risen by about 3.5 degrees Celsius to this day.”This year’s seasons in particular influenced the blossom dates, he added.

2021年成都七中高三英语上学期期末考试试题及参考答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项A“Why do I feel cold when I have a fever?” “Why does the sun rise in the east?” I knew the day would come when my little girl Sophie would learn to talk and inevitably (不可避免地) start askingthose questions. The questions themselves weren’t worrying me. I was actually looking forward to seeing where her curiosity would lie.What was bothering (烦恼) me was whether or not I would know the answers. In the age of the smartphone, this may seem like a silly worry. The answers to almost everything would be just one Google away.Still, I struggled with how I was going to prepare to become an all-knowing mother. Then one day, it struck me: I didn’t need to have all the answers. What a great example I could set if I let my daughter know that I, too, was still learning. And I realized how much more I could learn if I took another look at things I thought I already knew the answer to with the curiosity of a child. My little girl’s mind is a beginner’s mind--- curious, open to new ideas, eager to learn, and not based on knowledge that already exists. I decided that I would deal with her questions with a beginner’s mind, too.Once I decided to become more curious, I started noticing that curiosity was becoming more important in the workplace, too. It seems that leaders don't need to have all the answers, but they do need to be curious.Curious about curiosity, I searched for answers and found Albert Einstein’s famous words, “I have no special talent. I am only passionately (热情地) curious.” We mightquibble overthe view that Einstein had no special talent, but there is one thing for certain---he wouldn't have solved the puzzles of the universe without his passionate curiosity. Then I came across another Einstein quote, “The important thing is not to stop questioning. Curiosity has its own reason or existence.”1. The advantage of having a beginner’s mind is that ________.A. people can learn much faster.B. people won't be afraid to make mistakes.C. people are willing to receive new things.D. people won't be expected to answer all questions.2. What does the example of Einstein’s words show?A. Einstein was passionate about curiosity.B. Einstein’s quotes are very famous.C. Curiosity is of great significance.D. Curiosity is more necessary than talent.3. What does the underlined phrase “quibble over” in the last paragraph probably mean?A. Fight against.B. Argue about.C. Work out.D. Agree withBMy friend and I went traveling inTasmania,Australialast December. We settled in our Airbnb accommodation, a cozy apartment, not long after we arrived inHobart, the capital city.After briefing us on the kitchen's facilities and the whereabouts of the bedroom and bathroom, our hostess Geraldine resumed her ironing work, which seemed to have been interrupted by our arrival.She was ironing what looked like security guard uniforms, and we soon found out that she worked in a local prison. And when she detected the curiosity in our tones, she offered a tour at the prison in her SUV. My friend and I exchanged a “this is incredible” look and said “yes” immediately.As we drove, she told us about the buildings that we were passing, the local market and how to get to MONA,Tasmania's well-known contemporary art gallery.And of course we got to hear some background information about the prison. According to our hostess, it currently holds Martin Bryant, a notorious criminal who cheated 35 people out of their property. We could see the high level of security from the layers upon layers of wires surrounding the gray structure inside.Getting to know a city in such a local way is something I would never be able to do by talking to a hotel receptionist, and this is what I like best about the apartment-sharing experience, not to mention the fact that it's usually cheaper than hotel rooms.But I'm fully aware of the risks of Airbnb, which is why I did my homework before booking online—I checked the reviews of the accommodation to avoid possible safety problems.That said, it is the mutual trust between a host and a guest that fascinates me—the interesting feeling of building a bond with a total stranger.4. Why did the hostess drive us to the prison?A. She planned to send the uniform to the prison.B. She found our curiosity about the prison.C. She wanted to show off her SUV.D. She needed to offer a tour for us.5. Which of the following can best explain the word “notorious” in Paragraph 5?A. Unfamiliar to everyone.B. Particularly disappointing.C. Well known for being bad.D. Extremely generous to others.6. Compared with hotels, what is the writer's favorite of the Airbnb accommodation?A. It is cheaper in most cases.B. It supplies a better living condition.C. It offers a much safer accommodation.D. It provides a chance to know local culture.7. What does the author think of finding accommodation on Airbnb?A. Disapproving.B. Supportive.C. Neutral.D. Doubtful.CMove 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.”8. 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.9. What is mainly discussed about snowplow parenting in Paragraph 4?A. Its cost.B. Its benefits.C. Its popularity.D. Its ending.10. 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.11. 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.DHow much do consumers care about the carbon footprint of the products they buy? Would they care more if the goods were labeled with emissions（排放物）data?Does it matter at which stage in the lifecycle of a product the carbon is emitted? Research published in the International Journal of Environmental Policy and Decision Making offers a way to find out．Study participants view a carbon footprint label as similar to labels that have appeared on some existing products．The label shows the carbon dioxide emissions connected with their production, transportation, usage and disposal（清理）, thus showing the buyer the likely effect on climate change of buying a particular product．In the first group of studies, the research team proved that carbon emissions and a carbon emissions label would indeed play a role in consumer product decisions, although not as great a role as price．In a second set of studies, the team found that emissions connected with usage were most important to consumers followed by thetransportation and disposal stages．The carbon footprint of the producing process was considered less important to consumers than the other stages in the product's lifecycle because it is outside the consumer's control．That is, the participants felt they were less responsible for carbon emitted during producing process．Consumers value recycling a product, but the researchers found that, overall, the consumers would preferproducers to offset（补偿）carbon emissions rather than having toaddressthe problem directly themselves．Consumers are increasingly concerned with climate change problems, and already carbon labeling is appearing on some products．"We find that participantsnot only take the carbon label into account when making product decisions, but they want detailed information on the label," the researchers explain．They suggest that companies should prepare for how carbon emissions labels might affect future consumer choice．12. Which of the following most affects consumer's choice?A. Labels．B. Price．C Packaging． D. Carbon footprint．13. About the carbon dioxide emissions in the product's lifecycle, which stage do consumers care most?A. Usage stage．B. Transportation stage．C. Disposal stage．D. Producing stage．14. Which of the following can best replace the underlined word "address"?A. Look into．B. Point out．C. Deal with．D. Run into．15. What can be inferred from the last paragraph?A. Companies should take carbonemissions more seriously．B. All products have been labeled with carbon emissions data．C. Producers will attach less importance to carbon emissions labels．D. Products labeled with carbon emissions data will have poor sales．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。

Not quite, if we consider the state of second language learning in schools across the country. According to a 2018 study, Europe often tops the U.S. in foreign language education in school. 92% of European students are learning a foreign language in school. In America it’s only 20%. In more than 20 European countries, studying a foreign language for at least one year is compulsory. In comparison, only 10 states and D.C. require learning a foreign language for graduation.I went to a public school in Pennsylvania that ranked onNewsweek’s list of America’s top high schools in 2015. Foreign language learning was not a graduation requirement. A common response to such stories and statistics is: So what? Why should Americans care about learning another language when English has recently seemed to dominate as the official language of the world?The world is globalizing faster than we can imagine. More than half of the world’s population speaks more than one language. It is also increasingly becoming the need for success in this globalizing world. Having the ability to speak a second language opens up the possibility of travelling and immersing yourself in another part of the world. This means people can feel other cultures, and traditions in places you were previously kept away because you could not communicate in the language.The teaching of foreign languages can be instrumental in bringing about peace and unity in the country we live in. Learning a second language can be an efficient vehicle to help to bridge communities. To speak another language means having access to a universe of different experiences and world views of another community of people.4. Why does the writer mention Europe?A. America makes studying a foreign language compulsory.B. America is the glorious symbol of multiculturalism.C. America isn’t really qualified as the developed world.D. America doesn’t focus on foreign language education5. What is American’s attitude towards education of foreign languages?A. Less concerned.B. More worried.C. Quite doubtful.D. Very supportive.6. What can visiting people do if they can speak the language where they visit?A. Make the world globalizing.B. Achieve success in business.C. Experience people’s real life there.D. Keep away their own culture.7. What is the main idea of the last paragraph?A. Using a second language can bring harmony.B. Communities of people enjoy the great views.C. Speaking another language is reallynecessary.D. Learning a second language can be difficult.CTeens who have good, supportive relationships with their teachers enjoy better healthas adults, according to research published by an American research center.“This research suggests that improving students' relationships with teachers could have positive and long-lasting effects beyond just academic success," said Jinho Kim, a professor atKoreaUniversityand author of the study."Itcould also bring about healthimplicationsin the long run.”Previous research has suggested that teens' social relationships might be linked to health outcomes in adulthood. However, it is not clear whether the link between teen relationships and lifetime health is causal（因果的）-it could be that other factors, such as different family backgrounds, might contribute to both relationship problems in adolescence and to poor health in adulthood. Also, most research has focused on teens' relationshipswith their peers（同龄人）, rather than on their relationships with teachers.To explore those questions further, Kim analyzed data on nearly 20,000 participants from the Add Health study, a national study in theU.S.that followed participants from seventh grade into early adulthood. The participant pool included more than 3,400 pairs of siblings（兄弟姐妹）. As teens, participants answered questions, like “How often have you had trouble getting along with other students and your teachers?" As adults, participants were asked about their physical and mental health.Kim found that participants who had reported better relationships with both their peers and teachers in middle and high school also reported better physical and mental health in their mid-20s. However, when he controlled for family background by looking at pairs of siblings together, only the link between good teacher relationships and adult health remained significant.The results suggest teacher relationships are more important than previously realized and that schools should invest in training teachers on how to build warm and supportive relationships with their students. "This is not something that most teachers receive much training in," Kim said, “but it should be.”8. What does the underlined word “implications" in Paragraph 2 refer to?A. Recipes.B. Habits.C. Benefits.D. Risks.9. What is Paragraph 3 mainly about?A. Poor health in adolescence.B. Limitations of the previous research.C. Teens' relationships with their peers.D. Factors affecting health in adulthood.10. What does Kim's research show?A. Good adult health depends on teens' good teachers.B. Good family background promises long-term adult health.C. Healthy peer relationships leads to students' academic success.D. Positive student-teacher relationship helps students' adult health.11. Where does this text probably come from?A. A health magazine.B. A medical report.C. A term paper.D. A family survey.DIn a study published in Nature Machine Intelligence, researchers at Ohio State University show how artificialintelligence（AI）can follow clinical trials to identify drugs for repurposing, a solution that can help advance innovative treatments.Repurposing drugs is legal and not unusual. When doctors prescribe(开处方)drugs that have been approved by the Food and Drug Administration(FDA)for purposes different from what is printed on the labels, the drugs are being used “off-label” Just because a drug is FDA-approved for a specific type of disease does not prevent it from having possible benefits for other purposes.For example, Metformin, a drug that is FDA-approved for treating type 2 diabetes, is also used to treat PCOS(a disease of women), and other diseases. Trazodone, an anti-depressant with FDA-approval to treat depression, is also prescribed by doctors to help treat patients with sleep issues.The Ohio State University research team created an AI deep learning model for predicting treatment probability with patient data including the treatment, outcomes, and potential confounders(干扰因素).Confounders are related to the exposure and outcome. For example, a connection is identified between music festivals and increases in skin rashes(红疹). Music festivals do not directly cause skin rashes. In this case, one possible confounding factor between the two may be outdoor heat, as music festivals tend to run outdoors when the temperature is high, and heat is a known cause for rashes. When working with real-world data, confounders could number in the thousands. AI deep learning is well-suited to find patterns in the complexity of potentially thousands of confounders.The researcher team used confounders including population data and co-prescribed drugs. With this proof-of-concept, now clinicians have a powerful AI tool to rapidly discover new treatments by repurposing existing medications.12. What do we know about a drug used off-label?A. It is sold without a label.B. It is available at a low price.C. Its uses extend beyond the original ones.D. Its clinical trials are rejected by doctors.13. Metformin and Trazodone are similar as both of them________.A. are used off-labelB. treat rare diseasesC. result in sleep issuesD. are medical breakthroughs14. What can be inferred about “confounders”?A. They are possible treatments.B. They are environmental factors.C. They can be easily recognized in real-world data.D. They should be taken into serious consideration.15. What is the main idea of the text?A. AI examines benefits of existing drugs.B. AI identifies off-label uses for drugs.C. AI finds new drugs for common diseases.D. AI proves the power of drug research.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届成都七中高三英语期末考试试题及答案解析第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AEast Yorkshire has typical unpredictable British weather. So here are some ideas to keep everybody happy when the weather is not the most ideal.William's Den, North CaveThe outdoor and indoor areas are suitable for children of all ages to have fun.There are nests to explore, rope bridges to cross, a tree-house and a slide. The attached Kitchen provides fresh food made from locally sourced ingredients serving a selection of treats.East Riding Leisure CentresKnown for a fun learner pool alongside an incredible fun zone with two slides as well, it is perfect for kids to find their feet in the water, have fun and explore. Its 6 climbing walls offer a different challenge on each. This place is suitable for anyone over the age of 4 and you can refuel at cafe with fresh food, snacks and cakes.Sewerby Hall and GardensWhen the weather’s not sure, take cover in the Hall and learn how life was in the early 1900’s for the residents and workers of the house. Then explore the zoo and meet the pigs, parrots and penguins! Kids of all ages are welcome.Withernsea LighthouseThere’s no limitation to the age of kids to climb Withernsea Lighthouse, which is 144 steps to the top, with full views of the East Yorkshire Coast at the top of it. Enjoy the museum on the ground floor and learn what life is like working and living in a lighthouse. The souvenir shop provides attractive gifts for visitors at a fair price.1.Which one is unsuitable for kids of all ages?A.William’s Den, North Cave.B.East Riding Leisure Centres.C.Sewerby Hall and Gardens.D.Withernsea Lighthouse.2.Where can kids enjoy food?A.In William’s Den, North Cave and Sewerby Hall and Gardens.B.In East Riding Leisure Centres and Withernsea LighthouseC.In William’s Den, North Cave and East RidingLeisure Centres.D.In Sewerby Hall and Gardens and Withernsea Lighthouse.3.Where does this passage probably come from?A.A geography textbook.B.A science report.C.A finance magazine.D.A travel brochure.BHumans are the only creature that gets around by standing up and putting one foot in front of the other. Our ability to walk upright has allowed humankind to travel great distances and survive changing climates, environments and landscapes.Countless scientific studies have found that walking is really good for us and this simple act can provide a number of healthimplications, which help people live longer. In fact, a walking routine, if done properly, might be the only exercise people need.How much walking should one aim for? You’ve likely heard we need 10,000 steps a day. That’s about 5 miles. But contrary to popular belief, this recommendation doesn’t come from science. Instead, itis from a 1960s advertising campaign to promote a pedometer (计步器) in Japan. Perhaps because it’s a round number and easy to remember, it stuck.Since the 1960s, researchers have studied the 10,000-steps-a-day standard and have turned up mixed results. Although 10,000 steps is certainly a healthy and worthwhile goal, it’s not fit for all.For instance, a recent Harvard University study involving more than 16,000 senior women found that those who got at least 4,400 steps a day greatly reduced their risk of dying early when compared with less active women. The study also noted that these benefits continued up to 7,500 steps. This 7,500 mark isn’t surprising: It’s similar to common public health recommendations, such as the Centers for Disease Control and Prevention’s recommendation of 150 minutes of moderate (适度的) physical activity a week for adults.4. What does the underlined word “implications” in Paragraph 2 refer to?A. BenefitsB. Problems.C. Habits.D. Manners.5. Where does the 10,000-steps-a-day standard come from?A. A Harvard University study.B. Science research on health.C. A pedometer advertisement.D. Public health recommendation.6. What can we know from the last paragraph?A. 7,500-steps-a-day standard is the best choice for all.B. More than 16,000 old people were involved in the study.C. Those who walk at least 4,400 steps a day won’t die early.D. 150-minute moderate exercise a week for adults is advised.7. What does the author mainly want to tell readers?A. The more you walk a day, the healthier you will be.B. We can benefit from continuous and proper walking.C. Walking upright helps humankind to explore the world.D. Advertisements can always tell us some scientific suggestions .CAt first glance, there is nothing unusual about BingoBox’s convenience store–shelves packed with snacks line the walls, attracting passers-by through the glass windows. But upon closer look, BingoBox is no ordinary store. The door unlocks only after customers scan (扫描) aQR code to enter, and there is no cashier — just a lone checkout counter (柜台) in a corner. The Shanghai-based company is one of many unmanned store operators (运营者) opening outlets all over China, hoping to improve slim profit by reducing staff costs.“Ifstaff costs rise quickly, that puts greater pressure on low-profit businesses like convenience stores and supermarkets,” said Andrew Song, an analyst at Guotai Junan Securities. “InChina, manpower costs have been rising ly quickly.”However, the future vision of shopping without a check-out person is still a work in progress. A Post reporter who visited a BingoBox store inShanghaiwas briefly locked in when trying to exit without buying anything. Although a sign near the exit stated that empty-handed customers can leave by scanning a QR code, no QR code was to be found. Repeated calls to the customer service hotline went unanswered.The idea of unmanned stores first caught the world’s attention in December last year. Equipped with technology such as RFID tags, mobile payment systems and facial and movement recognition, such stores collect large amounts of data that give operators a better idea of consumer preferences and buying habits, which can then be used to optimize (使最优化) operations and make more efficient inventory decisions. For companies like BingoBox, lower operating costs also mean it can afford to expand its reach to areas with less foot traffic or fewer people, according to its founder and chief executive ChenZilin.8. What makes BingoBox store look like an ordinary convenience store?A. No cashier to check out.B. A lone checkout counter.C. Shelves packed with goods.D. Entering by scanning a QR code.9. Why are unmanned stores popular with operators?A. The customers prefer mobile payment systems.B. The unmanned stores help improve profit with lower labor costs.C. The employees focus on consumer preferences and buying habits.D. The operators care more about operations and inventory decisions.10. Why is the reporter’s case mentioned in the passage?A. To show his anger and dissatisfaction.B. To warn people not to go to a BingoBox store.C. To explain unmanned stores still have a long way to go.D. To complain that QR code service is not convenient at all..11. What can we infer from the chief executive Chen Zilin?A. Nowadays all stores should be equipped with advanced technology.B. The operators collect data about consumer preferences and buying habits.C. BingoBox made wiser decisions based on the data collected in those unmanned stores.D. The operators can open unmanned supermarkets in more distant places with low cost.DTo stay healthy and fit, Chinesestudents do group exercises every day at school. Most of you probably do the same set of exercises. But some school exercises have grown popular online due to their local and innovative designs.Singing in Sichuan dialects with energetic movements and unique mask-changing is not just a Sichuan Opera performance. It’s the routine exercise for students of Mianyang Foreign Languages Experimental School in Sichuan province.“Sichuan Opera is a local opera, and it is now facing a gap in inheritance (传承). Therefore, we cooperated with Mianyang Intangible Cultural Heritage Center to create a simple and easy-to-learn Sichuan Opera exercise,” said Shen Junhua, who is in charge of organizing the school’s exercise between classes.According to Shen, this new type of exercise has been practiced since 2017 and has been popular amongstudents. When students enroll (入学), they will spend several weeks practicing it. At present, almost all of the students and teachers have mastered it.“In fact, we had hardly heard of Sichuan Opera before teachers taught us how to do the Sichuan Opera exercise,” said Li Yangwenwen, 14, an eighth grade student who also joined the school’s Sichuan Opera club out of interest. “It’s very different from normal exercises. After practicing it, we found it very beautiful and became interested in it. Now, almost all of the students look forward to our daily exercise time and feel excited to do it.”“By combining opera with daily exercise, the daily class activity allows students to perceive and understand Sichuan Opera’s culture”, Shen said. “After years of continuous effort to spread the seeds of traditional culture, the younger generation is finally catching on.”12. What do students in Shen’s school do during the group exercise?A. They do normal exercise .B. They sing pop songs in Sichuan dialects.C. They do mask-changing in a Sichuan Opera performance.D. They combine group exercise with Sichuan Opera.13. Why do they adopt the new type of exercise?A. To attract new students to the school.B. To inherit local culture.C. To create an easy-to-learn exercise.D. To make the school’s group exercise popular.14. How do teachers and students react to the group exercise?A. Calm.B. Indifferent.C. Enthusiastic.D. Uninterested.15. What can we learn from the last paragraph?A. Shen’s continuous effort is highly praised.B. The younger generation will have a stronger body.C. The students can better understand their local culture.D. Students help to spread the seeds of traditional culture toyounger generation.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。

China Satellite Navigation OfficeBAge has never been a problem for 16-year-old Thessalonika Arzu-Embry. After all, she’s already got her master’s degree.The North Chicago-area teen started homeschooling at the age of 4. She began having an influence on others soon after. When she was 6 years old, she was an inspirational speaker at an organization called Tabitha House Community Service, which is for people who were forced to leave their homes because of earthquake, flood and other natural disasters.At the age of 11, she graduated from high school and then earned her bachelor’s degree in psychology in 2013. She completed those classes online as she was traveling for church events and leadership meetings.She doesn’t stop there, though. The teen plans to focus on aviation psychology (航空心理学) for her further study, a decision inspired by her father who is a pilot. She grew up around airplanes and took fights all the time. Her goal is to use it to help pilots deal with problems that could have deadly results once the plane takes off — a topic that has been in the news lately. For her, it’s a mix of two of her interests.In her free time, Thessalonika enjoys playing tennis, swimming and being active in her youth group at church. She also has three self-published books, which are on her site. Jump the Education Barrier is written to help students finish college, and in the future aims to help business owners with trends.

The Story of ThessalonikaB. To be a talentC. Three Published BooksD. HomeschoolingCIf 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 atree 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.”8. 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.9. 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.10. 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.11. 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.DThe cumulative rainfall in Henan province during the four days was the highest since the province has records, the provincial meteorological service said. The rain was heaviest in the provincial capital, Zhengzhou, for a short period on Monday and Tuesday. Northern, western and central parts of Henan also experienced downpours, the service said. Zhengzhou's biggest one-hour precipitation (降水量) —201.9 mmbetween 4 and 5 pm on Tuesday—was also the highest on the Chinese mainland. The previous record was 198.5 mmin the village ofLinzhuang in Zhumadian in August 1975, the National Meteorological Center said. The city's precipitation duringthe four days exceeded that of its average annual precipitation, the center said.Chen Tao, chief forecaster at the National Meteorological Center, said abundant water vapor (水蒸气) brought by Typhoon In-Fa and the province's special geographical features led to Henan's rain. “Partly affected by the typhoon, large amounts of water vapor have been transported to China's inland areas, including Henan,” he said.From Thursday to Monday, rain was forecast to continue in Henan. However, rainfall will gradually subside in Zhengzhou and the province's northern and central regions, though the storms will increase the risk of mountain torrents and other geological disasters. By Monday, lighter rain is forecast for parts of Henan, the provincial weather service said. However, local authorities are still urged to bevigilantand prepare to prevent or cope with flooding and other possible disasters.Predicting such weather events remains a challenge worldwide because it involves many meteorological phenomena, the center said. “The formation of this kind of extreme weather, including rainstorms and high temperatures, is complex,” Chen said. “We still lack effective solutions and methods for such forecasting”, he said. “We are now putting a lot of effort into tackling the difficulty. We believe that as the technology improves, we can better forecast the events.”12. What message does the author mainly want to convey in the first paragraph?A. heavy rain fell in Zhengzhou.B. The rain in Henan lasted four days.C. Zhumadian also suffered the similar heavy rain.D. Henan experienced the biggest rainfall of all time.13. What can be indicated from Chen Tao's words?A. It is not easy to forecast the extreme weather.B The rain of Henan is mainly caused by Typhoon In-Fa.C. The center hasn't put a lot of effort into solving the problem.D. Rainstorms and high temperatures can account for the heavy rain.14. What does the underlined word “vigilant” probably mean?A. Relaxed.B. Alert.C. Reluctant.D. Communicative.15. Where might the text be most probably taken from?A. history book.B. A novel.C. A news report.D. A science magazine.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年成都七中高三英语期末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AOn Friday morning when 53-year-old Thong Pham broke into the house through the unlocked back door, he took a steak knife from the kitchen.It was dark, and the family didn't know what Marley was barking (吠) at. Taylor, Amber and their girls Finley, 6,and Sadie, 4, soon woke up and came downstairs, too. “Well, it was dark so we couldn't see anything, only could hear Marley,” Amber recalled, saying her husband then went for the lights. “And once he turned the hall light on, we realized that the guy was holed up in the corner trying to hide.”“So I think he got to the front door and realized he couldn't get out, and by that point in time, Marley's got him cornered,”Taylorsaid. Pham slashed (砍) both Marley and Taylor, and blood went everywhere. Taylor shared a video summary to his Facebook page, where he said Marley was stabbed (刺) up to six times, mostly around the head and neck area. “And as I pulled back, blood shot out of my arm,”Taylorcontinued. “She got him pretty good and I got him pretty good in the face.”“But it was really hard because I was trying to make sure that my husband wasn't going to die,” Amber explained, adding that she was trying to protect their two girls. “When he realized that the two girls were in the house, that's when he kind of backed up and started running. "Taylorexpressed gratitude to everyone for their thoughts and prayers. And the family is thankful for their dog Marley.“She's our hero,” Amber said. “If it hadn't been for her, that guy could have gone in the...he could have gone to their rooms or something.”Tayloradded, “Yeah, I mean, the story plays out very differently if Marley's not there.”1.

Forgiveness.B. Concern.C. Anger.D. Appreciation.BWe all use different ways to remember ideas, facts and things we need to store. Remembering is an extremely important part of our learning experience. Information process, storage and recall encourage purposeful learning.But the brain doesn’t store everything we want or need for future use. It makes choices and tends to remember information that forms a memorable pattern. Things you learned recently can be particularly difficult to remember because they haven’t taken root in your mind.“Forgetting allows us to remember what is really important to our survival. We forget much of what we read, watch, and think directly every day.” writes John Medina in his book, Brain Rules.How do you avoid losing 90%of what you’ve learned? An inspiring writer and speaker Zig Ziglar once said: “Repetition is the mother of learning, the father of action, which makes it the architect of accomplishment.”Repetition has been a remembering skill for ages. When you hear or read something once，you don’t really learn it-at least not well enough to store the new information for long. The right kind of repetition can do wonders for your memory. People learn or remember better by repeating things or getting exposed to information many times. Othersrepeat particular steps or processes deliberately a number of times or even years to become better at certain skills.Daniel Coyle explains in his book, The Little Book of Talent:“...closing the book and writing a summary, even short ones, forces you to figure out the key points, process and organize those ideas so they make sense, and write them on the page. When you pick it back up weeks later, reread all of your notes or highlights to strengthen the ideas even further.”People learn by repeating things. Better learning is a repetition process. Every time we repetitively access something we already know, we increase the memory’s stored value.4. Which of the following can be inferred from the passage?A. The brain tends to store 90% of the things we learn.B. The fresher the information isthe easier to remember.C. Thinking is more important than remembering in study.D. The brain tends to choose and keep what it thinks important.5. How does the writer prove his opinion?A.By giving examples.B. By listing numbers.C. By borrowing words of experts.D. By providing scientific finding.6. What does Daniel Coyle want to say in his book?A. You can’t pay too much attention to repetition.B. Summarizing is a very effective learning tool.C. Forgetting forces human brain to make choices.D. Regular repetition helps to form good habits.7. Which do you think is the best title of the passage?A. How the Brain WorksB. Reading for MoreC. Fighting Against ForgettingD. Repeat to RememberCA study has found that a lifetime of regular exercise and activity can slow down the aging process (衰老过程). Researchers say that getting older should not necessarily mean becoming more weak or sick. Their research shows that a devotion to a life of movement and exercise may help us live not only longer, but also healthier.For their study, the researchers looked at two groups. The first group was made up of 125 non-professional cyclists between the ages of 55 to 79. This group included 84 healthy men and 41 healthy women. We will call this group the “cyclists”.Researchers then found 130 people to make up a second group. Within this group, 75 people were aged from 57 to 80. The other 55 were between the ages of 20 and 36. The people in this group were also healthy, but they did not exercise regularly. We will call this group the “non-exercisers”. Smokers, heavy drinkers of alcohol and people with other health issues were not included in the study.Then, researchers gave both groups a series of tests. They tested their muscle mass (肌肉质量), muscular strength, percentage of body fat and the strength of their immune (免疫的) systems. Then the researchers compared the results of the two groups.Results showed that the cyclists did not experience body changes usually regarded as a normal aging process. For example, they did not lose muscle mass or muscular strength. Also, their body fat did not increase with age.The researchers also found something they had not expected. The study showed that the immune systems of the cyclists did not age either.The researchers advise us all to find an exercise that we like in our lives.8. How did the researchers carry out the study?A. By comparing.B. By discussing.C. By imagining.D. By reasoning.9. Which of the following is a result of the research?A. The cyclists kept a thin body shape.B. The non-exercisers gained weight easily.C. The cyclists’ muscles remained strong with age.D. The non-exercisers usually had health problems.10. Which is an unexpected result for the researchers?A. The cyclists had normal aging process.B. The cyclists’ immune systems didn’t age.C. The cyclists lost nearly all their fat.D. Everyone needed an exercise in their lives.11. Which of the following can be the best title for the text?A. Healthy People Need More ExerciseB. Take an Exercise, the Harder, the BetterC. Cycling Is the Best Way to Prevent AgingD. A Lifetime of Exercise Slows Aging ProcessDLas Vegascity inNevadais built in a desert. The city may be known to the outside world for its partying. But officials have found that there are 21 square kilometers of useless grass. The grass is never laid on, played on or even stepped on. The grass is only there to look nice.Now, the city is asking theNevadastate legislature to ban useless grass. It is trying to become the first place inAmericato ban that kind of grass often seen between streets, in housing developments and in office parks.It is estimated that useless grass makes up 40% of all the grass inLas Vegasand it needs a lot of water to survive. Grass needs four times more water than dry climate plants like cactus. By tearing out the grass, the city could reduce yearly water usage by 15%.In 2003, the Southern Nevada Water Authority banned developers from planting grass in front of new homes. It also offered homeowners $ 30 for each square meter of grass they tear out. But fewer people are now using theprogram. Water usage has increased in southernNevadaby 9% since 2019. And last year,Las Vegaswent a record 240 days without major rainfall. The Colorado River provides much ofNevada's drinking water. The river could lose more water as climate change affects it.Water officials in other dry cities said water usage needs to be reduced. But they fear the reaction to reforms like the ones inLas Vegasif their communities do not accept them. Cynthia Campbell is the water resources adviser for the city ofPhoenixinArizona. “There might come a point when city restrictions get too severe for some residents. They'll say that is the point of no return for them,”Campbellsaid. “For some people, it's a pool. For some people, it's grass.”12. Why doesLas Vegascity try to ban useless grass?A. To protect the local people.B. To beautify the city.C. To reduce water usage.D. To reduce waste.13. What program was carried out inLas Vegasin 2003?A. Allowing planting grass before new houses.B. Encouraging the residents to tear out grass.C. Praising those who signed on the program.D. Awarding those who reduced water usage.14. What is implied inCampbell's words in the last paragraph?A. Many residents won't follow the ban.B. Reaction to the reform will vary personally.C. Other measures should be taken to protect wetter.D. Water officials should take many factors into account.15.

As of 6 p.m. Tuesday, 14 peoplehad been rescued from the capsized vessel, with five others confirmed dead. The rest are still missing, although rescuers said there could be more survivors. Strong winds and heavy rain are hampering rescue efforts.The Eastern Star sank in only 15 meters of water “within one or two minutes” of being caught in freak weather in Jianli, according to the ship’s captain and chief engineer who survived the incident. The ship left the eastern Chinese city ofNanjingon May 28 bound forChongqingMunicipality.The ship was carrying 403 passengers, five tour guides, and 46 crew, rather than the previously reported 47. Most passengers were tourists fromShanghaiand its neighboringprovinceofJiangsu, aged between 3 and 83, with most in their 60s and 70s.The 76.5-meter-long and 11-meter-wide vessel has been in service for nearly 20 years and can carry up to 534 people. It is owned by Chongqing Dongfang Shipping. Waterway officials said they have no record of the company being involved in any previous sinking incidents.According to weather forecast, most of the Yangtze basin will be subject to downpours over the next 10 days, with heavy rain expected in the area where the search is underway.Police, waterway authorities and fire departments have sent more than 150 boats and over 4,000 personnel to the scene. The Chinese Navy has sent diving forces to search for the missing. The team is composed of soldiers from the navy’s fleets in the North Sea, East China Sea, andSouth China Sea, as well as students of the Naval University of Engineering.

The author’s purpose of writing the text is most likely to ________.A. informB. explainC. describeD. entertainCThe term "bird brain" is frequently used to describe a person's lack of intelligence and good decision-making ability. However, some scientists believe it should be considered a praise, given that many birds can perform human tasks like producing and using tools, solving problems, and planning for future needs. Now,Griffin, an African Grey parrot, has proved that birds may even possess better visual memories than human adults and children.The study, led by Hrag Pailian, a researcher at Harvard University, had the parrot compete in the game against twenty-one undergraduate students and twenty-one 6 to 8-year-old children. The popular challenge involves hiding a small object under one of three or more upside-down cups, which are moved around. Participants are required to accurately identify the cup under which the object lies. To make the task more challenging, the researchers required participants to track two, three, and four objects at the same time.An analysis of the results showed thatGriffinoutperformed the 6 to 8-year-olds across all levels on average. Even more impressive, the "bird brain" performed as well as, or slightly better than, the 21 Harvard students on 12 of the 14 trials! It was only in the final two tests, which had the most objects and most movement, that the parrot fell behind the adults. However,Griffin's performance was never below that of the children.Griffinwas the candidate of choice because the scientists needed an animal that had a brain functionality similar to that of humans. "The fact that the smart parrot loves to show off his brain power in exchange for a few cashews (腰果) did not hurt either", said Irene Pepperberg, a Harvard lecturer, who has trained Griffin and several other African Grey parrots, has been studying the species for over four decades and is considered a pioneer in the study of bird intelligence.8. Whatwere the participants required to do in the study?A. Identify different kinds of objects.B. Tell where the hidden object lies.C. Track other participants' performance.D. Move around upside-down cups.9. What did the results of the study indicate?A. 6 to 8-year-olds did better thanGriffin.B. Parrots have a better memory than other birds.C. Harvard students have a better visual memory.D.Griffinoutsmarted Harvard students in some trials.10. Why wasGriffinchosen for the experiment?A. It was good at making decisions.B. It was specially trained for experiments.C. It had similar brain functions to human beings.D. It loved to show off his language power for some treats.11. What is the best title for the text?A. "Bird brain" becomes a term for a stupid person.B. Harvard lecturer pioneers in bird intelligence study.C. Parrot outsmarted Harvard students in visual memory test.D. Researchers made new discoveries about human intelligence.DA smiling panda and a walking Chinese lantern will be the mascots of the 2022 Winter Olympics and Paralympics (残奥会）in Beijing .The mascots were known to the public on Sept.17, 2019 at a ceremony inBeijing.

2021届成都七中实验学校中学部高三英语上学期期末考试试题及答案解析第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项ATheatre reflects the values of the civilization out of which it grows. The following are the types of theatre performances an ancient Roman might have witnessed then.Fescennine VerseFescennine Verse was a pioneer of Roman comedy. Ironic and improvisational（即兴的）, it was used mainly at festivals or weddings, and as invective. With early native Italian funny dialogues in Latin verse, it was thought to have combined with a tradition of performances by masked dancers and musicians from Etruria.Fabula AtellanaFabula Atellana relied on common characters, masks, direct humor, and simple plots. They were performed by actors improvising. Fabula Atellana came from the Oscan city of Atella. There were 4 main types of characters: the braggart, the greedy blockhead, the clever hunchback and the stupid old man, like modern Punch and Judy shows.Fabula TogataNamed for the clothing symbolic of the Roman people Fabula Togata had various subtypes. One was the Fabula Tabernaria, named for the tavern（酒馆）where the comedy’s preferred characters, lowlifes, might be found. One describing more middle-class types, and continuing the Roman clothing theme, was the Fabula Trabeata.Fabula PraetextaFabula Praetexta is the name for Roman tragedies on Roman themes, Roman history or current politics. Fabula Praetexta was less popular than tragedies on Greek themes. During the Golden Age of drama in the Middle Republic, there were four great Roman writers of tragedy, Naevius, Ennius, Pacuvius, and Accius. Of their surviving tragedies, 90 titles remain.All the performances above began as a translation of Greek forms, even to the extent of their being performed in Greek costume.1.Where might an ancient Roman witness Fescennine Verse?A.At a party.B.At a funeral.C.At a wedding.D.At a concert.2.Which type of performance describes the middle-class life?A.Fabula Atellana.B.Fabula Tabernaria.C.Fabula Trabeata.D.Fabula Praetexta.3.What do the listed types of performances have in common?A.They copy Latin dramas.B.They take on Greek forms.C.They reflect Roman themes.D.They refer to Italian stories.BMusic is said to be a universal language. But for Chase Burton, a deaf filmmaker fromTexas, music has always been a totally different experience.“When I was a kid, I’d lie on the floor so I could feel the vibrations (震动，颤动) from my brother’s band rocking out below my body, ” the 33-year-old man said. “That was one of the first times I began building a relationship with music.”In 2016, his ability to experience music changed dramatically, thanks to California-based technology company Not Impossible Labs. It designed a vibrating suit that enables deaf people to “feel” music through their skin. Consisting of a body harness (背带), ankle and wrist belts, the suit translates audio into a range of vibrating pulses that are felt at 24 contact points.Burtonhas been trialing the suit for four years.“The sound hits different parts of your body, ” saidBurton. “Maybe it will strikeme down in my ankles first. And then I’ll start to feel the vibrations in my back. And then I’ll feel some pulsations in my wrist.”The creators want to extends the tactile (触觉) musical experience beyond the deaf community. In 2018, they gave out 150 of the suits at a rock concert inLas Vegaswhere half the audience members were deaf and half were able to hear.Since then, Not Impossible Labs has been working to improve the technology and says it’s ready to go to market soon. Eventually, the creators want the suit to become a consumer product, accessible to all. The company’s talent and business development director, Jordan Richardson, said that the technology could be used in live sports broadcasts, video games and theme parks.As a writer and director who’s been working to make the movie world more accessible,Burtonhopes that the vibrating suit will be available to his film audiences in the future. He believes the suit canenhanceemotions while watching a movie – for hearing as well as deaf people. “I see the tech as a real opportunity to help people understand that music for movies doesn’t always need to be enjoyed through the ears”.4. Why would Chase Burton lie on the floor when he was a kid?A. To feel some pulsations in his wrist.B. To feel the vibrations from his brother’s band.C. To expand the tactile musical experience.D. To begin building a bond with films.5. What do we know about Not Impossible Labs from the passage?A. It was started by Chase Burton in 2016.B. Its products have been used in live sports broadcasts.C. It is a technology company based inCalifornia.D. Its administrative director is Jordan Richardson.6. Which can replace the underlined word “enhance” in the last paragraph?A. createB. expressC. coverD. strengthen7. What is the best title for the passage?A. Vibrating Suit Allows Deaf People to “Feel” MusicB. Tech Company Provides Free Suits for Deaf PeopleC. Deaf People Enjoy Rock Music with Free SuitD. Movies Need to Be Enjoyed Through the EarsCPeople from Britain and Ireland first came to live in Australia in 1788. They brought different dialects (方言) of English with them. These different kinds of English began to mix and change. The newcomers soon began to speak with their own typical accent (口音) and vocabulary. More and more people came to Australia during the Gold Rush in the 19th and 20th centuries. Some came from Britain and Ireland; others came from non-English speaking countries. Australian English continued to grow and change.Australian English has also been influenced by American English. During the Second World War, there were many American soldiers staying in Australia. More importantly, American television shows and music have been popular in Australia since the 1950s.Australians use many words that other English speakers do not use. The famous Australian greeting, for example, is G’day! A native forest is called the bush and central Australia is called the outback. Many words were brought to Australia from Britain and Ireland. For example, mate means “friend”, and it is still used in Britain. Some of these words have changed in meaning. Some words have come from Australian original languages, manyof which are names for animals, plants and places, like dingo and kangaroo.Australian spelling comes from British spelling. In words like organise and realise, -ise is the expected and taught spelling method. In words like colour, favourite, -ouris the normal, but nouns such as the Labor Party and Victor Harbor are spelled with -or. Program, on the other hand, is more common than programme.There are also differences in the definition (定义) of words Australians use in different parts of the country. For example, football means “rugby” in New South Wales and Queensland, but “Australian rules football" in everywhere else in Australia. In New South Wales, a swimming costume is called a cossie or swimmers, while in Queensland it is called togs and bathers in Victoria.8. What does paragraph 1 mainly talk about?A. Reasons why English is important.B. Different dialects of Australian English.C. Various aspects that Australian English has been influenced.D. Changes of the accent and vocabulary in English.9. According to the text, which of the following is spoken only by Australians?A. Mate.B. Outback.C. Program.D. Rugby.10. Which is the following can best describe Australian English?A. Confusing and interesting.B. Multicultural and creative.C. Crazy and boring.D. Unchangeable and mixed.11. What might be the best title for the text?A. The History of AustraliaB. The Birth of Australian EnglishC. The Development of Australian EnglishD Different Kinds of English Across the WorldDVietnammade preparations for theLunar New Year with a fish release on Thursday. The tradition involves releasing fish called carps into rivers and lakes in the country a week before the holiday known as Tet officially begins.The tradition comes from an ancient story of three “Kitchen Gods”. The three, two males and a female, take aride on the brightly color1 ed carp at the end of the year. They go to Heaven to meet with the Jade Emperor, the God who rules there. The “Kitchen Gods” report news about the families they represent to seek the emperor's care and protection. Their efforts help to keep the kitchen fires burning, and families happy and healthy.As the Gods go to Heaven, families clean their houses in preparation to celebrate Tet. A clean house, Vietnamese believe, will bring luck in the new year. On Lunar New Year's Eve, the Gods will return to Earth and their duties in the kitchen of the house.Thursday's event inVietnamthis year was more controlled than ever before because of COVID-19. It is spreading in several northern areas of the country. However,Vietnamhas increased contact examination, mass testing, and quarantine measures to slow the spread. The aggressive action has limited infections and deaths in the country.“Vietnamese will still follow the tradition of releasing the fish, but COVID-19 has made people keep a safe distance,” said Tran Van Toi as he released a carp from a plastic bag atHanoi'sWestLake.This year, due to COVID-19, there were fewer people releasing fish there, but there was a major change in attitude towards plastic bags.

2021届成都市第七中学高三英语上学期期末考试试题及答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AThe Origins of Famous BrandsOur lives are full of brand names and trademarked products that we use every day. Although many brand names are simple acronyms(首字母缩略词) or versions of their founders names, some of the companies we trust every day actually have fascinating and surprising back stories.StarbucksIt seems fitting that the most famous coffee brand in the world would take its name from one of the world’s greatest works of literature. The inspiration for the name of the coffeehouse came from Herman Melville’sMoby Dick. The founders’ original idea was to name the company after the Captain Ahab’s ship, but they eventually decided that Pequot wasn’t a great name for coffee, so they chose Ahab’s first mate, Starbucks, as the name instead.GoogleGoogle was originally called Backrub, for it searched for links in every corner of the Web. In 1997, when the founders of the company were searching for a new name showing a huge amount of data for their rapidly improving search technology, a friend suggested the word “googol”. When a friend tried to register the new domain (域) name, he misspelled “googol” as “google”.NikeOriginally founded as a distributor for Japanese running shoes, the company was originally named BRS, or Blue Ribbon Sports. In 1971, BRS introduced its own soccer shoe, a model called Nike, which is alsothe name for the Greek goddess of victory. In 1978, the company officially renamed itself as Nike, Inc.The right name is essential to a company’s success, and a great origin story is just as important as a great product. An attractive origin story is one more thing that keeps customers guessing, wondering, and buying its products.1. What is the name of the Captain Ahab’s ship?A. Moby Dick.B. Starbucks.C. Pequot.D. Herman Melville.2. Why did the founders of the Google want to change its name?A. They mistook their name.B. They wanted new customers.C. The company’s original name was too long.D. The company’s search technology was improving rapidly.3. Where does the importance of the origin story of one company lie in?A. It can change the company’s image.B. It can add myth to the company.C. It explains the development of the company to customers.D. It makes customers imagine and purchase its goods.BCanadaIs Our NeighbourCanada and the United States are neighbours.They are on the same land.They share the same long boundary(国界).These two nations are similar in many ways.Canada buys many goods from the United States.Cars and clothes are two examples.The United States also buys goods from Canada.Much of the paper used in the United States comes from Canada.Some of the oilweuse comes from Canada,too.Americans travel toCanadaon holiday.And Canadians often visit the United States.It is easy for the people of one country to go to the other country.Canadians read about the United States in newspapers and magazines.Many Americans watch Canadian baseball and hockey (曲棍球)matches on Sundays.However,there are important differences between theUnited Statesand Canada.The United States has more people.Because the population is smaller,there are more open places in Canada.There is much unused land.This is another important difference.4.Canadabuys from theUnited States.A.oil and paperB.nothingC.many thingsD.everything5.In the first paragraph “we” means ________.A.CanadiansB.AmericansC.ChineseD.students6.The people in theUnited Stateslike Canadian ________.A.baseballB.basketballC.newspapersD.oil7.Which of the following statements is WRONG?A.Canada has less people than theUSA.B.Canada has not used all the land.C.Canada is connected withAmerica.D.Canadians don’t like hockey.CScientists have recently discovered thatAndean condors (秀鹫)— some of the world’s largest birds——barely flap their wings at all while flying. Instead, they use rising air currents to remain in the air for hours.The Andean condor is the world’s largest soaring bird. They can weigh up to 15 kilograms. Their wings, when spread out, measure up to three meters. Their main food source is the meat of large animals which have died. Soaring high in the sky allows condors to easily spot possible meals on the ground.Scientists worked together to study the flight patterns of these huge birds and how much effort the birds use when flying. To study the birds while they were in the sky, the researchers attached special devices which could record every beat of their wings.The scientists learned that most of the condors’ flapping— over 75%— came when the birds were taking off. Once in the sky, the birds flew for very long periods of time without flapping at all. In fact, they only flapped their wings for 1% of the time they were in the air. One bird flew for over five hours without flapping, covering nearly 117miles.Soaring without flapping is important because birds bum energy every time they flap their wings.The birds’ soaring isn’t magic. They use the fact that hot air rises to keep themselves up. As hot air rises, it often creates “thermals”— currents of warm air moving upward. The condors soar by making use of these thermals. The tricky part is finding thermals and moving between them.When birds are forced to land and take off again often, it costs them a lot of energy. The researchers learned that to avoid having to land, the condors did most of their non-take-off flapping when they were closer to the ground and looking for a new thermal.The scientists reported that even though all of the condors they studied were young, they knew well how to take advantage of the air currents.8. What can we learn about the Andean condor from the text?A. They live mairly on small animals.B. Their wingspan is at least three meters.C. They rely on hot air to remain high in the sky.D. They are the birds with the strongest flying ability.9. Why was the equipment tied to the birds?A. To measure how far they could fly without flapping.B. To keep track of how often they flapped while flying.C. To calculate the energy required for their flight.D. To confirm their flight patterns.10. Which of the following acts consumes the most energy for a condor?A. Hunting for food.B. Flying in the sky.C. Getting off the ground.D. Landing on the ground.11. What can we infer from the text?A. Condors flap the most when looking for a new thermal.B. No condor can fly for more than five hours without flapping.C. Condors don’t need to look for thermals when soaring in the sky.D. Soaring by using thermals is probably a natural ability of condors.DThis year researchers expect the world to snap 1.35 trillion photographs, or about 3.7 billion per day. All those pixels (像素) take up a lot of room if they are stored on personal computers or s phones, which is one reason why many people store their images in the cloud. But unlike a hard on drive which can be encrypted to protect its data, cloud storage users have to trust that a tech platform will keep their private pictures safe. Now a team of Columbia University computer scientists has developed a tool to encrypt (加密) images stored on many popular cloud services while allowing authorized users to browse and display their photographs as usual.Malicious (恶意的) attempts to access or leak cloud-based photographs can expose personal information. In November 2019, for example, a bug in the popular photograph storage app Google Photos mistakenly shared some users' private videos with strangers. Security experts also worry about employees at cloud storage companies on purpose accessing users' images.So the Columbia researchers came up with a system called Easy Secure Photos (ESP), which they presented at a recent conference. “We wanted to see if we could make it possible to encrypt data while using existing services,” says computer scientist Jason Nieh, one of the developers of ESP. “Everyone wants to stay with Google Photos and not have to register on a new encrypted-image cloud storage service.”To overcome this problem, they created a tool that preserves blocks of pixels but moves them around to effectively hide the photograph. First, ESP's algorithm (算法) divides a photograph into three separate files, each one containing the image's red, green or blue color1 data. Then the system hides the pixel blocks around among these three files (allowing a block from the red file, for instance, to hide out in the green or blue ones). But the program does nothing within the pixel blocks, where all the image processing happens. As a result, the files remain unchanged images but end up looking like grainy black-and-white ones to anyone who accesses them without the decryption (解密) key.12. What's probably the main purpose for people to store images in the cloud?A. To save storage room.B. To make photos beautiful.C. To try a new storage way.D. To keep their privacy safe.13. Why might employees in cloud storage companies be distrusted by experts?A. They sell users' passwords.B. They have invented new tools.C. They often let out personal information.D. They may steal a glance at users' images.14. What's the advantage of ESP?A. It can provide clear images.B. It can decrease the upload time.C. It can classify images automatically.D. It can encrypt data on the original platform.15. What does paragraph 4 mainly talk about?A. Method of decryption.B. Image-processing technique.C. Separate files of images.D. Data analysisof color1 s.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届成都市第七中学高三英语上学期期末考试试卷及参考答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AThe COVID -19 pandemic has affected all aspects of life, including the way we travel. But for those who are looking to expand their horizons while still staying safe, the following three travel trends in 2021 may provide inspirations. Let’s take a look.StaycationWith many travel restrictions during the pandemic, people preferred traveling to nearby places in 2020. This trend continues in 2021. According to search data, 62 percent of people are interested in taking a vacation within driving distance of home. People who live in large cities want to get back in touch with nature. Travelers are looking for places different from their everyday accommodations, for example, farm stays, villas and cottages.Pod travelWhile 2020 saw a rise in solo travel and isolated adventures, 2021 shows that people want to be more connected. “Pod travel”, or gathering in isolated spaces with loved ones, is growing in popularity. 85 percent of survey respondents favor traveling with family or friends, and over half of the trips searched include three or more people. Pod travel is here to stay for those who want to safely be together while reducing risks associated with socializing with others.Remote working and travelingMany people worked and learned from home in 2020 because of the pandemic. Remote working blurs the line between working and traveling. There was a 128 percent increase in the mention of phrases such as “relocation”, “relocate”, “remote work” and “trying a new neighborhood”. People are actively booking longer stays (e. g. two plus week trips) in small to mid—size cities with access to immersive natural surroundings and wide—open spaces.1.What can we learn about Staycation?A.Travelling to the countryside.B.Taking an isolated adventure.CHaving holidays in nearby places. D.Staying indoors all by oneself.2.What’s special about Pod travel?A.Traveling alone.B.Traveling far away.C.Traveling while working.D.Traveling with loved ones.3.Where might we find the text in a magazine?A.Medicine.cation.C.TourismD.Career.BScientists have long sought to prevent sharp memories from dulling with age, but the problem remains unsettled. Now research published in Scientific Reports suggests virtual reality might help older people recall facts and events based on specific details.The study involved 42 healthy older adults from the San Francisco Bay Area. Half spent a dozen hours over four weeks playing a virtual-reality game called Labyrinth; they wore headsets and walked in place, walking virtual neighborhoods while completing small tasks. The other half, in the control group, used electronic tablets to play games that did not require recalling details. After 15 sessions (期), the latter performed roughly the same as before on a long-term memory test. But the Labyrinth players gain an improvement in memory through the VR game. A scientist Peter Wais of the University of California said the improvements brought them up to the level of another group of younger adults taking the same memory tests.Meredith Thompson, an education researcher, studies learning through VR games but was not involved in the new study. It would be great to actually follow people over time and see what this type of game does for long-term memory. She says, adding VR can provide greater involvement than other games. Wais's team is now investigating how long the observed effects last and which elements of the training have the most impact.A cognitive (认知)psychologist, Daniel Simons, who was also not involved in the study, notes experiments with other games that claim to train the brain have often failed to evaluate this. And it remains unclear how test performance in a laboratorysetting might translate to real-world situations. The outcome, Simons notes, “needs to be repeated, ideally with a much larger group, before it’s treated as a strong finding.”For now, Wais says, the team hopes its studies with similar-sized groups will help draw funding to test the game in a larger pool of participants.4. What is the passage mainly about?A. People's memory gradually fails as they age.B. People of different ages should play VR games.C. Virtual reality changes people's memory.D. Virtual reality improves older adults' memory.5. What is Meredith Thompson's attitude toward the research?A. satisfied.B. enthusiastic.C. cautious.D. concerned.6. According to the scientists, the research needs to be improved due to ________.A. the lack of financial support.B. the limited pool of participants.C. the unsatisfying test performance.D. the impractical application in real world.7. Where may the passage come from?A. A novel.B. A review.C. A magazine.D. A guidebook.C“One person’s trash is another person’s treasure.” That’s a common expression, but the next time you throw something away, think about a twist on the old saying. What if your trash could become your own treasure? Many creative, thrifty, and environmentally minded people have come up with a way to makethathappen. It’s called upcycling. Our world would be a better place if everyone would begin upcycling.Upcycling is the practice of taking an unwanted item and turning it into something useful. For example, how about that pair of jeans with a hole in one knee? It could become a new pillow for your bedroom.Upcycling is not the same as recycling. Upcycling is actually much better for the environment. Recycling takes an item made of glass, paper, metal, or plastic, breaks it down to its base material, and then uses that material to make another product. This requires a great deal of energy. On the other hand, when you choose to upcycle, the only energy you use is your own. And upcycling not only reduces the amount of trash that goes into our landfills, but it also protects natural resources, such as oil and gas. Recycling is good for the environment, but upcycling is even better.Upcycling also makes a family’s budget stretch further. Of course, the idea of reusing items to save money is not new. During the Great Depression in the 1930s, many families lived on a tight budget. People had to use what they already had in order to meet their needs.As responsible citizens, we should all be concerned with protecting our environment and budgeting our resources. Upcycling is a fun and creative way to help. The next time you go to toss something into the trash can, stop and think about what it could become. Chances are, there’s a brand-new item in your hand just waiting to be upcycled.8. Why does the author mention an old saying in the first paragraph?A. To arise reader’s awareness of upcycling.B. To stress the importance of upcycling.C. To lead in the topic of upcycling.D. To show the idea of upcycling.9. Which one below belongs to upcycling?A. An old ladder is transformed into a bookshelf.B. Old tin cans are transported to landfill.C. A broken wooden door is chopped up.D. Old cloth is made into a paper bed.10. What is the difference between recycling and upcycling?A. Upcycling is much more creative.B. Recycling is much easier to achieve.C. Recycling is much more cost-saving.D. Upcycling is much more energy-efficient.11. What can be inferred from the text?A. Upcycling is popular at present.B. Upcycling is replacing recycling.C. Upcycling is worth recommending.D. Upcycling is a tradition in daily life.DSophie became friends with the gray squirrels during her first week atPennState, after spotting them running around and wondering what they would look like with tiny hats on their heads. Today, everyone at the university knows her as the “Squirrel Girl”.Sophie tried bringing them food, and gradually they began to trust her. She managed to put a hat on a squirrel and take a picture. Thinking that her colleagues could do with something to lift their spirits, she started posting similar photos on Facebook. The response was greatly positive, and before long Sophie and her squirrels became an Internetsensation.Growing up in a neighborhood outside ofState College, Sophie was always fond of birds and animals around her home, but she didn't interact with people very much. She was later diagnosed (诊断) with Asperger's syndrome, but the squirrels changed that. “The squirrels help me break the ice, because I'll be sitting here pattinga squirrel and other people will come over and well just start like feeding the squirrels together and chatting about them,” she said, “I am a lot more outgoing.”And in case you're wondering how Sophie is able to get the squirrels to do what she wants for her photos, it has a lot to do with food. For example, whenever she wants them to hold or play with something, she puts peanut butter on the prop (道具), and they'll grab it. In the beginning, she would throw peanuts up the trees on campus and invite the squirrels to come down and get them, but they hesitated to approach her. She had the patience to earn their trust, though.This year, Sophie is graduating with a degree in English and wildlife sciences. She wants to be a science writer and educate people on how to preserve the environment. As for her furry friends, Sophie plans to stay in the area and visit them as often as she can.12. What does the underlined word “sensation” in paragraph 2 mean?A. Event.B. Hit.C. Service.D. Addiction.13. What can we learn about Sophie according to paragraph 3?A. She got lots of friends due to squirrels.B. She used to be a popular girl in her childhood.C. She lived in the far countryside when young.D. She was more outgoing than before.14. How did Mary manage to take photos of squirrels wearing hats?A. By attracting them with food.B. By putting them in cages.C. By playing music to them.D. By dressing like squirrels.15. What do you think of Sophie?A. Tolerant and capable.B. Sociable and aggressive.C. Patient and caring.D. Indifferent and appreciative.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届成都七中高三英语上学期期末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ALocated besideLake Geneva, the Olympic Museum houses more than 10,000 artificial objects and hours of interactive contents highlighting some of the best moments during the Olympics. Here are some of the museum’s most moving moments.The Olympic ParkThe journey through the Olympic Museum begins in the Olympic Park, an 8,000-square-meter outdoor area in front of the museum overlooking Lake Geneva and theAlps. The park contains artwork and sculptures that show respect to the world of sport.The first Olympic symbolThe “Olympic Rings” flag was designed by Coubertin in 1913. The rings represent the five continents that participate in the Olympics: Africa, Asia,America,AustraliaandEurope. The six color1 s include at least one color1 that is represented on the flag of every country.The stadiumsThe stadiums that host the Olympic Games are as much of a celebration of design as the games are a celebration of sportsmanship. Guests can explore plans and models of Olympic stadiums’ past and present, including one of the games’ most attractive stadiums, the Bird’s Nest from Beijing 2008 Olympics.The Olympic medalsHave you ever wondered what an Olympic medal looks like? The Olympic Museum has a room that houses every bronze, silver, and gold medal from every Olympic Games dating back to the first modern Olympics of 1896. Each medal design is a unique representation of the year and location in which the games were held.1.Which moment do you see first when exploring the Olympic Museum?A.The Olympic Park.B.The first Olympic symbol.C.The stadiums.D.The Olympic medals.2.What do you know from The first Olympic symbol?A.The first modern Olympics took place inGreece.B.There are six color1 s on the flag of every country.C.Australia used to be the largest continent on earth.D.The “Olympic Rings” flag was created in 1913.3.What can you do in the section of The stadiums?A.Admire the view ofLake Geneva.B.Meet some famous designers.C.Enjoy the model of the Bird’s Nest.D.Talk with guests of honour.BWith their tiny brains and excellent ability to memorize nectar locations, honeybees are a favorite model organism for studying learning and memory. Such research has indicated that to form long-term memories—ones that last a day or more—the insects need to repeat a training experience at least three times. By contrast, short-and mid-term memories that last seconds to minutes and minutes to hours, respectively, need only a single learning experience.Exceptions to this rule have been observed, however. For example, in some studies, bees formed long-lasting memories after a single learning event. Such results are often regarded as circumstantial anomalies, says Martin Giurfa of the University of Toulouse. But the anomalous findings, together with research showing that fruit flies and ants can form long-term memories after single experiences, aroused Giurfa’s curiosity. Was it possible that honeybees could reliably do the same? Giurfa reasoned that the ability to form long-term memories might depend on the particular type of bee and the experience. Within a honeybee colony, there are nurses, who clean the hive and feed the young; guards, who patrol and protect the hive; and foragers, who search for nectar.While previous studies have tested bees as a whole, Ciurfa and his colleagues focused on foragers, tasking them with remembering an experience relevant to their role: an odor associated with a sugary reward.The researchers observed that a single exposure to a reward-paired odor was enough for most forager bees to remember that specific odor the following day. Many foragers could even remember the odor three day later.The results do not mean that all prior research was wrong, says André Fiala of the University of Göttingen. “People have done the experiments in a different way.” Still, the new results do show that “the commonly held belief that one needs multiple training trials to achieve long-term memory is not always true,” he says, and this “really advances the field.”4. What does the author want to tell us through Paragraph 1?A. A model for memory research.B. The classification of memories.C. New research on learning and memory.D. Previous findings on memory formation.5. Which factor might influence a bee’s memory of an experience, according to Giurfa’s research?A. Whether the bee's role is related.B. Whether the bee is introduced or native.C. How often the bee repeats the experience.D. How long the bee is exposed to the reward.6. What is Andre Fiala’s attitude towards the new results?A. Doubtful.B. Favorable.C. Intolerant.D. Unclear.7. Which of the following is a suitable title for the text?A. Learning and Memory: How Honeybees RememberB. Honeybee Memory: Honeybee Knows What to DoC. Honeybees Remember after Just One LessonD. Honeybees Use Memory for CommunicationCThe annual 3-to-4-millimeter rise in sea levels is expected to impact many coastal communities in the coming decades. However, few are as defenceless as the Republic of theMaldives, a collection of more than a thousand picturesque islands in theIndian Ocean. NASA researchers believe that parts of what is “arguably the lowest-lying country in the world” will become uninhabitable by 2050, due to wave-driven flooding and limited freshwater. To fight the unavoidable, the government recently revealed plans for the world's first 'true' floating island city.The aptly-named Maldives Floating City (MFC) is the brainchild of Dutch Docklands, a global leader in floating infrastructure (基建). According to the March 13, 2021, announcement, the new city will be constructed on a 200-hectare lagoon (环礁湖) located just 10 minutes by boat from the Maldivian capital, Male. It will initially consist of a thousand waterfront residences, arranged in a series of honeycomb-like maze rows. The developers plan to add hotels, restaurants, shops, and even a school and a hospital in the near future. The floating structures. will be attached to the surrounding islands, which will form a base and provide protection from high tides.Maldive officials aim to make MFC as self-sufficient as possible. Freshwater storage will provide drinking water for residents, while floating solar blankets and agriculture fields will take care of their energy and food needs.“ThisMaldivesFloatingCitydoes not require any land rehabilitation, therefore has a minimal impact on the coral reefs,” explains Mohamed Nasheed, Speaker of Parliament. “What's more, giant, new reefs will be grown to act as water breakers. In theMaldives,we cannot stop the waves, but we can rise with them.”Construction of the revolutionary city is expected to begin in 2022 and be completed in phases over the next five years. If successful, it will provide a blueprint for other countries facing a similar situation.8. Why doesMaldivesdecide to build MFC?A. It is the lowest-lying country.B. It will be flooded soon.C. It is running out of fresh water.D. It will be unsuitable for living.9. What is Paragraph 2 mainly about?A. The prospect of MFC.B. The developers of the plan.C. The location of the residences.D. The barriers to the construction.10. What can we infer from the underlined words?A. MFC will keep waves away.B. MFC will make use of waves.C. MFC will adjust to the waves.D. MFC will work as water breakers.11. What's the writing purpose of this passage?A. To introduce a construction program.B. To appeal to people to protect nature.C. To seek international help forMaldives.D. To report the achievement of a city plan,DIn someareas ofCalifornia, it’s so dry that farmers aren’t willing to plant crops this season. Growers, north ofSan Francisco, have begun pulling out of local farmers markets.CountyLineHarvest, which farms more than 30 acres inPetaluma, hasn’t had enough water to grow all the peppers, lettuces and other produce for a long time, according to a video on its Instagram page. Nearby farms arc saying the same, emphasizing (强调) the effect of theextendeddry periods.Californiagrows a third of theUnited States' vegetables and two-thirds of the nation's fruits and nuts. If dry weather prevents farmers from growing plants, that could lead to pushing up the price of food that's already starting to affect theU.S.economy.“Due to severe drought, for the first time in 21 years, we will not be able to grow this summer inPetaluma,"CountyLinesaid in its post.Drew Lerner, president of World Weather Inc. inKansas, saidCalifornia“missed the rainy season" and won't see much moisture (水分) over the next several months.A La Nina weather pattern in the Pacific pushed winter storms north and away from the state, leaving it with less moisture than usual. AsCaliforniagets most of its water from winter storms, little relief is expected before October.That has left growers such as Shao Shan Fann in a bind. The business can’t offer the selection of Asian vegetables and Bay Area staples it usually grows at its Bolinas location, according to its website.Nearby, Green Valley Community Farm has access to only about 5% of the water it usually relies on, owner David Plescia said. He’s looking for new land with enough water to use, and also has a permit in the works to grow cannabis to make up for the lost income. If it doesn’t make it, he’ll leave the fields empty.“It’s part of our generation’s cross to bear, figuring out how to run small — or medium-scale farm businesses in this kind of atmosphere of highly variable rainfall,” Andrew said.12. What does the underlined word “extended” in the second paragraph mean?A. Hot.B. Short.C. Long.D. Wonderful.13. Which is the result if the dry weather stops famers from planting crops?A. Theincreaseinthe priceof food.B. The growth of economy inU.S.C.Lessmoisture than usual.D. The low price of Asian vegetables.14. From what Andrew said, we can infer (推断) all of the following statements EXCEPT that________.A. The climate is not very goodB. It is part of the burden for people of his generationC. It is hard for him to run his farm businesses insuch bad climateD. He is sure that the serious drought will come to an end soon15. What does the passage mainly talk about?A. How do the famers run businesses inCalifornia.B. How does the owner look for new land with enough waterC. California farmers facing drought choose not to plant crops.D.

He is optimistic about the WFH trend.BTyphoons can be deadly — in 2013, Typhoon Haiyan, the strongest ever recorded, was responsible for 6,340 deaths—and cost billions in damages. Current forecast modelscan only predict these storms 10 days in advance, at most, and they cannot precisely predict how intense the storms will become.An international team of researchers has developed a model that analyzes nearly a quarter of Earth’s surface and atmosphere in order to better predict the conditions that birth typoons.“The target problem of this study is how to foretell the birth of typhoons,” said paper author Mingkui Li, associate professor in the Key Laboratory of Physical Oceanography in the Ocean University of China and the Pilot National Laboratory for Marine Science and Technology (QNLM). “We specifically address three aspects: the beginning time, inner pressure and maximum wind speed.”The researchers also accounted for the influence of one variable(变量) on another, such as wind speed on sea surface temperature. This influence is well understood and accounted for in climate predictions and in weather forecasts, butithas not been fully applied in understanding how long-term climate affects day-to-day weather, according to Li. “We aimed to provide insights on the time scale that can be used to forecast typhoons in advance.”From their study, the researchers determined that a model with the ability to better understand the relationship between warm sea surface temperatures and weak wind movement— conditions that favor typhoon formation—could improve typhoon predictability.“Our goal is to develop a 10 to 30-day prediction system that will lead to seamless(无缝的) weather-climate predictions.” Shaoqing Zhang, paper author and professor in the Key Laboratory of Physical Oceanography, said.4. What is the problem with the present forecast system?A. It cannot foretell storms in advance.B. It is ineffective in accuracy and timeliness.C. It costs too much and causes great damages.D. It can hardly predict the intensity of typhoons.5. What does the underlined word “it” in paragraph 4 refer to?A. The variable.B. The climateC. The temperature.D. The influence.6.

In fact, there are 36 million blind people worldwide and a quarter of them are in India; however, many cases of blindness in India are curable. The poor in India have limited access to primary eye healthcare and often do not eat foods rich in micronutrients, like vitamins and minerals, which play an important role in maintaining good eye health.Many people worldwide are not even aware that they may have a vision (视力) problem simply because they do not get their eyes tested every year with a doctor, who tests for the functioning of the eye muscles (肌肉), as well as common diseases like night blindness. This exam is strongly recommended by experts because some changes in vision, which the patient may take longer to notice, can be found easily in this way.Certain simple changes in diet and lifestyle can ensure better eye health for you. These include drinking plenty-of water, not smoking, and eating brightly color1 ed and leafy fruit and vegetables. Wearing sunglasses protects your eyes from the sun, which damages otherwise healthy eyes. Learn about your family's eye disease history, and be on the lookout for any problem about your vision. Make sure that you see a doctor immediately for early intervention(干预) if you see any of these signs of worsening eye health.If you or a loved one needs to cure blindness or other eye diseases, turn to a crowdfunding (众筹) platform. A group of eye health caregivers have fundraised with crowdfunding platform ImpactGuru to raise money toperform operations on the eyes of blind women in south Asia. Running an online fundraiser enables both doctors and patients to find a way out of the dark. If you want eye care to develop, start a fundraiser today.8. Why are there so many blind people in India?A. There is a lack of eye hospitals in India.B. People pay no attention to their eyes at all.C. Poor Indians lack food good for eye health.D. The environment damages their eyes.9. What does the author suggest in Paragraph 2?A. Examining your eyes annually.B. Strengthening muscles every day.C. Raising the awareness of physical health.D. Attaching importance to self-examination.10. Which of the following may do harm to your eyes?A. Smoking a lot.B. Wearing sunglasses.C. Drinking much water.D. Watching brightly-color1 ed pictures.11. What does the author want to show in the last paragraph?A. How to start a fundraiser online.B. The importance of raising money.C. The role of crowdfunding in eye care.D. What should bedone to raise money.DThe China International Search and Rescue Team(CISAR) was formed in 2001 and is now made up of several hundred rescue workers and about 20 police dogs. The team brings help and hope to those whose lives are changed by astorm, flood, earthquake, or any other natural disasters.After long and careful training, the team went on its first international rescue tasks in 2003. That year, the Chinese team helped save lives after earthquakes inAlgeriaandIran. It was the first time that a Chinese team had worked outsideChinawhose members won high praise for bravery and skill.Since then, the CISAR has completed many tasks. The list of people to whom help has been given is long. The team treated more than 3,000 people who were wounded in the 2006 earthquake inIndonesia, helped 2,500 wounded people after the earthquake that hitHaitiin 2010, and spent several months giving aid to over 25,000people suffering from the 2010 floods inPakistan. On April 26, 2015, a group of 62 people from CISAR went toNepalafter the 8.1 magnitude earthquake that happened there.Rescue workers are trained to find people, treat wounds, and hand out food, water, and other supplies. They have to be able to do work that is difficult under conditions which can be very dangerous. After a disaster, there is usually no electricity or water, and there may be diseases and other dangers. Rescue workers get to save lives, but they must also bury the dead. That means they have to be strong in both body and mind.Rescue workers must have big hearts, too. It takes a lot of love and courage to risk one’s own life to save someone else’s. The members of the CISAR have plenty of both and are always ready to go wherever help is needed.12. What is the function of the numbers in Paragraph 3?A. To advertise for the CISAR.B. To add some basic information.C. To praise Recue Workers’ contributions.D. To stress the dangers Rescue Workers face.13. What is the author’s attitude towards Rescue Workers?A. Hopeful.B. Respectful.C. Curious.D. Supportive.14. What are the last two paragraphs mainly about?A. The duty rescue workers must perform.B. The qualities rescue workers must own.C. The difficulties rescue workers must go through.D. The willingness rescue workers should require.15. What may be the best title of the passage?A. China to the RescueB. How to train CISARC.

2021届成都市第七中学高三英语期末考试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AIt was a weeknight and one of my twin daughters marched into the room, waving a book she'd finished. “Dad, why are books with science in them always about boys?” she asked.I told her that simply wasn't true; there were loads of great science fictions with girls in them. She agreed, but argued that in those stories it was the boys who were doing science, and the girls were justalong for the ride. My other daughter took her sister's side and challenged me to give an example.This left me in a difficult position. I could either go through our library to point out some wonderful examples of female-led science fictions, or just admit they were right and remain in my comfortable chair.I've been asked several times how I came up with the idea forA Problematic Paradoxand my answer is always the same: it came to me in a moment of inspiration. I like that answer because it's simple and makes me seem very creative. The fact that this explanation is not true bothers me from time to time. Here's the truth: the story wasn't my idea. It was my daughters who suggested I write something for them that had a girl doing science.My daughters were at an age when many young women turn away from STEM (science, technology, engineering, and math), believing those areas of study unfriendly or out-of-the-norm for girls. I also read about how important role models can be to young people. It's one thing to tell a person they can do something, but seeing someone like them doing that thing can be more powerful.So, I kept two guidelines for the book in mind: First, the story had to be fun for anyone, because it's as important for boys to understand that science is for everyone. Second, I wanted the main character, Nikola, to be imperfect. She should be someone with shortcomings as we all have. I think this not only makes a story more interesting to read, but also helps make it clear that the most extraordinary things can be done by ordinary people.1. What does the underlined phrase “along for the ride” in paragraph 2 probably mean?A. Entering a bike race.B. Offering vital help.C. Doing unimportant things.D. Playing the leading role.2. What do we know about the bookA Problematic Paradox1?A. Its main character is perfect.B. It is a female-led science fiction.C. It is intended to appeal to girls only.D. Its idea comes from the author's inspiration.3. Which of the following best describes the author's book?A. Serious and abstract.B. Simple and practical.C. Creative and well-organized.D. Inspiring and interesting.BCoke was introduced by the Coca Cola company in 1886, making it a rather true andtested favorite of generations of people in over 200 countries. This list should give you some ideas on how to get more from your coke than usual.. Coca Cola is an excellent rust buster (除锈剂). If you have a bunch of small rusty objects, put them in coke overnight and give them a goodscrubin the morning. Coke helps to break down the rust, making cleaning much easier. Be sure to throw out the used coke when you are done with it or you might be taking a trip to the doctor.. Like the previous item, the citric acid (柠檬酸) in coke makes for an excellent window cleaner. This is especially useful for car windows. Pour a can of coke over the window and rub the window, then wipe it off with a wet cloth to remove any sugary matter from the sugar in the drink. As coke is fullof sugar, you should clean the sticky matter off the window glasses, or it will be not a cleaner but a dirt.. For those of you who live in areas where skunk (臭鼬) smells can be an issue from time to time, one can of coke added to water with detergent (清洁剂) really helps to break the smell down. If you have been sprayed, stand in the shower and cover yourself from head to toe with coke — wait for a few minutes, then wash yourself with a shower. Coke is an excellent hair treatment so you get two tips for the price of one with this item!. Pots can sometimes get black on the bottom. The black is almost impossible to remove; this is caused by over-cooking. To remove the black and renew your pot, pour in a can of coke (or as much as you need to cover the blackened area by an inch) and put it on the stove on a low heat. After an hour or so, wash the pot as normal.4. What does the underlined word “scrub”in Paragraph 2 probably mean?A. Start.B. Cleaning.C. Shake.D. Example.5. What is important while using coke to clean car windows?A. Use a dry cloth.B. Rub the window lightly.C. Don’t pour too much coke.D. Clean the sugary matter thoroughly.6. For which purpose does coke have to be mixed with other material?A. To get rid of the black on the pot.B. To breakdown the rust,C. To remove smells.D. To clean windows.7. What type of writing is this text?A. An advertisement.B. A review.C. A news report.D. A practical guide.CGlobal food demand will double by 2050, according to a new projection, and the farming techniques used to meet that unprecedented(空前的) demand will significantly determine how severe the impact is on the environment, researchers said.The study researchers warned that meeting the demand for food would clear more land, increase nitrogen(氮) use and significantly add to carbon dioxide and other greenhouse gas emissions.“Agriculture’s greenhouse gas emissions could double by2050 if current trends in global food production continue,” study researcher David Tilman, of theUniversityofMinnesota, said in a statement. “This would be a major problem, since global agriculture already accounts for a third of all greenhouse gas emissions.”The researchers studied various ways in which the increasing food demand could be mentioned. They found that the most environmentally friendly and cost-effective approach would be for more food producers to adopt the nitrogen-efficient “intensive” farming method, which involves the heavy use of labor and the production of more crops per acre.This approach was shown to be more effective than the “extensive” farming currently practiced by many poor nations, a method that includes clearing more new land to produce more food.Different farming methods produce significantly different yields, the researchers found — in 2005, the crop yields for the wealthiest nations were more than 300 percent higher than what the poorest nations produced.According to their analysis of the effects of extensive farming, if poorer nations continue using this method, by 2050theywill have cleared an area larger than theUnited States, about 2.5 billion acres. However, if wealthy nations help poorer nations to improve food yields by incorporating(吸收) intensive farming practices, that number could be reduced to half a billion acres.The researchers stress that the environmental effects of meeting future food demand depend on how global agriculture expands and develops.“Our analyses show that we cansave most of the Earth’s remaining ecosystems by helping the poorer nations of the world feed themselves,” Tilman said.8. What is the best title of this passage?A. The World Will Need Double Food by 2050B. Man Will Face the Risk of Lacking Food in the FutureC. Future Farmers Hold Environment’s Fate in Their HandsD. Different Farming Methods Produce Significantly Different Yields9. The character of the extensive farming is ________.A. very cost-effectiveB. to produce more crops per acreC. at cost of more new land to produce more foodD. very environmentally friendly10. It can be inferred from the passage that ________.A. poorer nations mainly use the intensive farmingB. wealthy nations mainly use the extensive farmingC. the intensive farming needs less food producersD. the extensive farming has a worse effect on ecosystems11. According to the passage, the underlined word “they” in the 7th paragraph refers to “________”.A. poorer nationsB. the effects of extensive farmingC. wealthy nationsD.future food demandDIf you go into the forest with friends, stay with them. If you don’t, you may get lost. If you get lost, this is what you should do. Sit down and stay where you are. Don’t try to find your friends—let them findyou. You can help them find you by staying in one place. There is another way to help your friends or other people to find you. You can shout or whistle three times. Stop. Then shout or whistle three times again. Any signal given three times is a call for help.Keep up shouting or whistling. Always three times together. When people hear you, they will know that you are not just making a noise for fun. They will let you know that they have heard your signal. They will give you twoshouts or two whistles. When a signal is given twice, it is an answer to a call for help.If you don’t think that you will get help before night comes, try to make a little house with branches(树枝). Make yourself a bed with leaves and grass.When you need some water, you have to leave your little branch house to look for it. Don’t just walk away. Pick off small branches and drop them as you walk in order to go back again easily. When you are lost, the most important thing to do is to stay in one place.12. If you get lost in the forest, you should _________.A. try to find your friends in no timeB. stay in one place and give signalsC. walk around the forestD. shout as loudly as possible13. Which signal is a call for help?A. Crying twice.B. Shouting here and there.C. Whistling everywhere in the forest.D. Shouting or whistling three times together.14. When you hear two shouts or two whistles, you know that _________.A. someone needs your helpB. something terrible will happenC. people will come to help youD. someone is afraid of an animal15. What’s the meaning of the last paragraph?A. Use branches to make a bed.B. Drop branches to look for water.C. Pick off branches to build another house.D. Leave branches to help you find your way back.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年成都七中高三英语上学期期末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AOlder adults who sleep six hours or fewer a night may have elevated risk for dementia(痴呆症) and other cognitive (认知的) issues, a new study finds.Researchers at Stanford University measured seniors' (ages 65 to 85) dementia risk and cognitive abilities, finding higher risk in those patients who regularly slept six or fewer hours compared to those who slept seven or eight hours. Those seniors who slept nine or more hours also had lower cognitive functions and other health issues, but the researchers didn't find the same high dementia risk in this group.The findings demonstrate how important it is for adults to maintain a healthy sleep cycle, especially as they get older.As adults age, it's common for their sleep patterns to change or becomedisrupted— leading to longer, shorter, or more irregular sleep. This disruption may be linked to Alzheimer's and other forms of dementia, impacting seniors' ability to remember information, problem-solve, and go through everyday behaviors. Sleep disruption can also be caused by or heighten depression, cardiovascular disease（冠心病）, and other conditions.A recommended sleep time for seniors is seven to eight hours, the researchers said. Six or fewer hours corresponded to short sleep, while nine or more hours corresponded to long sleep.The Stanford researchers measured levels of beta amyloid, a protein in the brain that is typically found in high levels when a patient develops Alzheimer's. In addition, the researchers used several tests for memory, attention, spatial skills, and executive function to identify patients' cognitive abilities. Those patients sleeping for six hours or fewer a night were more likely to develop dementia, the researchers found. The low-sleep patients had higher levels of beta amyloid.The Stanford researchers found that patients with lower sleep also performed worse on memory tests, while those with higher sleep (more hours) performed worse on executive function tests，which measure the brain's ability to switch between different tasks.―The main takeaway is that it is important to maintain healthy sleep late in life, Winer told CNN.1. What does the underlined word “disrupted” in paragraph 4 mean?A. difficultB. disorderedC. dissolvedD. different2. According to the findings, which of the following is NOT related to the disrupted sleep?A. It is more likely to cause old people to have bad memories over issues.B. It may contribute to dementia, cardiovascular disease and other illnesses.C. Some daily behaviors perhaps differ from those whose sleeping is normal.D It tends to bring all the old people to undergo brain scans and cognitive tests.3. What can we infer from the study?A. A proper sleep time for seniors is seven to eight hours.B. Low and high sleep patients were both poor at memory tests.C. Executive function test is applied to measure the capacity of brain.D. Keeping a healthy sleep for older adults late in life is crucial.BOne day, when I was working as a psychologist（心理学家）in England, an adolescent boy showed up in my office. It was David. He kept walking up and down restlessly, his face pale, and his hands shaking slightly. His head teacher had referred him to me.“This boy has lost his family,” he wrote. “He is understandably very sad and refuses to talk to others, and I’m very worried about him. Can you help?”I looked at David and showed him to a chair. How could I help him? There are problems psychology doesn’t have the answer to, and which no words can describe. Sometimes the best thing one can do is to listen openly and sympathetically（同情）The first two times we met, David didn’t say a word. He sat there, only looking up to look at the children’s drawings on the wall behind me. I suggested we play a game of chess. He nodded. After that he played chess with me every Wednesday afternoon---in complete silence and without looking at me. It’s not easy to cheat in chess, but I admit I made sure David won once or twice.Usually, he arrived earlier than agreed, took the chess board and pieces from the shelf and began setting them up before I even got a chance to sit down. It seemed as if he enjoyed my company（陪伴）. But why did he never look at me?“Perhaps he simply needs someone to share his pain with,” I thought. “Perhaps he senses that I respect his suffering.” Some months later, when we were playing chess, he looked up at me suddenly.“It’s your tum,” he said.After that day, David started talking. He got friends in school and joined a bicycle club. He wrote to me a fewtimes, about his biking with some friends, and about his plan to get into university. Now he had really started to live his own life.Maybe I gave David something. But I also learned that one…without any words---can reach out to another person. All it takes is a hug, a shoulder to cry on, a friendly touch, and an ear that listens.4. When he first met the author, David .A. felt a little excitedB. looked a little nervousC. walked energeticallyD. showed up with his teacher5. David enjoyed being with the author because he .A. wanted to ask the author for adviceB. liked the children’s drawings in the officeC. beat the author many times in the chess gameD. needed to share sorrow with the author6. What can be inferred about David?A. He liked biking before he lost his family.B. He recovered after months of treatment.C. He went into university soon after starting to talk.D. He got friends in school before he met the author.7. What made David change?A. The author’s silent communication with him.B. His teacher’s help.C. The author’s friendship.D. His exchange of letters with the author.CIn 2015, a man named Nigel Richards memorized 386, 000 words in the entireFrench Scrabble Dictionaryin just nine weeks. However, he does not speak French. Richards’ impressive feat is a useful example to show how artificial intelligence works — real AI. Both of Richard and AI take in massive amounts of data to achieve goals with unlimited memory and superman accuracy in a certain field.The potential applications for AI are extremely exciting. Because AI canoutperformhumans at routine tasks —provided the task is in one field with a lot of data — it is technically capable of replacing hundreds of millions of white and blue collar jobs in the next 15 years or so.But not every job will be replaced by AI. In fact, four types of jobs are not at risk at all. First, there are creative jobs. AI needs to be given a goal to optimize. It cannot invent, like scientists, novelists and artists can. Second, the complex, strategic jobs — executives, diplomats, economists — go well beyond the AI limitation of single-field and Big Data. Then there are the as-yet-unknown jobs that will be created by AI.Are you worried that these three types of jobs won’t employ as many people as AI will replace? Not to worry, as the fourth type is much larger: jobs where emotions are needed, such as teachers, nannies and doctors. These jobs require compassion, trust and sympathy — which AI does not have. And even if AI tried to fake it, nobody would want a robot telling them they have cancer, or a robot to babysit their children.So there will still be jobs in the age of AI. The key then must be retraining the workforce so people can do them. This must be the responsibility not just of the government, which can provide funds, but also of corporations and those who benefit most.8. What is the main purpose of paragraph 1?A. To introduce the topic.B. To mention Nigel’s feat.C. To stress the importance of good memory.D. To suggest humans go beyond AI in memory.9. Which of the following best explains “outperform” underlined in paragraph 2?A. Be superior toB. Be equal toC. Be similar toD. Be related to10. Which of the following jobs is the most likely to be replaced?A. The writer.B. The shop assistant.C. The babysitter.D. The psychologist.11. What does the text suggest people do about job replacement of AI?A. Limit the application of AI to a certain degree.B. Get more support from the government.C. Apply for the donation from companies.D. Upgrade themselves all the time.DI waschecking out at the supermarket counter on Wednesday night, ready to pay for my bananas, when all ofa sudden, fear came upon me. My wallet was gone. And I could only have left it one place: the G9 bus, from which I had gotten off minutes earlier and which was now speeding to some stops. The moment of realizing it was gone was followed by mental math. How much time and money would it cost to replace the credit cards, the driver's license, the expensive lipstick ($ 55!).Two hours after I was back at my house, I heard a knock on the door. My husband answered while I sat in the dining room on the phone with a credit card company. "Does Jennifer live here?" I heard someone say. In her hand was my wallet, without a penny missing. She left before I could offer my gratitude to her.After I posted the story, I heard from her boyfriend, who identified the good citizen as Erin Ball, a 26-year-old girl working for a trade organization.Once I figured out her, I called to thank her. She said she spotted my wallet and thought that it's more dangerous to go to a stranger's house than leaving the wallet with the driver, but she still decided to take the chance. "If I were in that situation, I would want someone to try to find me," she said. Ball doesn't find her actions particularly excellent. She added, "It's not hard to do small things for people."After Ball found my wallet, she decided to post a picture of my driver's license online before going to my house, trying to see if anyone knew me. No sooner had she left my doorstep than I got emails from two neighbors who recognized my face, both offering to help me find my missing property.Ball found my house on a bitterly cold night,for which I was extremely grateful. Looking back, I'm not surprised someone had wanted to help a stranger. A warm current of honesty and harmony is running through this town.12. What do we know about the author according to paragraph 1?A. She missed the G9 bus.B. She paid for her bananas.C. She replaced the credit cards.D. She found she had left her wallet on the bus.13. Who helped the author find Ball?A. The G9 driver.B. The girl's boyfriend.C. The author's neighbors.D. The author's husband.14. What did Ball do first after finding the wallet?A. Ball called the author.B. Ball went to the author's house.C. Ball gave the wallet to the bus driver.D. Ball posted a photo of the author's driving license.15. Which of the following best describes Erin Ball?A. Humorous and kind.B. Generous and demanding.C. Honest and warm-hearted.D. Caring and outgoing.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。
