2021届汕头市东厦中学高三英语一模试题及答案
2021届汕头市东厦中学高三英语一模试题及答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AMy mother and her best friend Martha were in their mid-80s when they saw each other for the last time.They had been friends since they were 18, both of them students atWesleyanCollegeinMacon,Georgia. My mother was the dreamy one, who loved to read and dream herself as an actress. Martha, however, was more practical. I’m not sure what they had in common except that they trusted each other, helped each other, and stayed in touch even when life separated them.Martha spent most of her adulthood inAtlanta, where she raised three kids. My mother, meanwhile, raised eight children, and moved many times during her financially and emotionally troubled marriage, which included several months living with her family inseedymotels.I sensed my mother hid her troubles from most people, but not from Martha, and I knew from my mother that Martha carried her own sorrows. Their willingness to share sorrow without judgment was part of what bond them.The best friendships can also withstand (抵挡) periods without communication. They didn’t communicate a lot — this was before the ease of emails and texts and yet I knew they were always in each other’s minds.One day in 2008, 1 drove my mother to Martha’s house for their final visit. The moment my mother hobbled (蹒跚) into Martha’s house, they threw their arms around each other and went to sit out in the garden, laughing until they were dizzy. I snapped a photo, and spotted something joyous, young and free on my mom, which existed only in the presence of her best friend.Two years later, my mother died. Of all the people I had to tell, Martha was the hardest because I felt it erased her past. After that, we lost touch. But I still think of her and how that friendship strengthened my mother.1. What does the underlined word “seedy” in Paragraph 3 probably mean?A. largeB. dirtyC. urbanD. bright2. The author’s mother and Martha had a lasting friendship partly because they________.A. were willing to shareB. were constantly in touchC. had much in commonD. had a likeness in personality3. What is the author’s purpose in writing the text?A. To tell the importance of friendship.B. To express his gratitude to his mother.C. To share his standard of choosing a friend.D. To praise the friendship between Martha and his mother.BWhen a United Kingdomsupermarket chain promised to move its farms to Net Zero by 2030, it made it clear that the effort would require working on many different fronts. From energy consumption and land - use change to methane emissions (甲烷排放), cattle farming comes with environmental challenges. So even if recent studies suggesting it's possible to cut methane emissions 80% do turn out to be accurate, there's still a very long way to go for most cattle farming to get anywhere close to truly net zero.Organic Valley, when producing milk, might be closer to that goal. It made headlines in 2019 by going 100% renewable (可再生的). Now the company is expanding on that tradition by starting a major loan initiative (贷款计划) to help its farm suppliers adopt renewable energy too.Created with Clean Energy Credit Union, the $ 1 million loan fund will deliver loans at below - marketrates. Specifically, the money will be made available to Organic Valley's 1, 700 farmer members, and can be used for a variety of projects.“We are focused on a whole systems approach to renewable energy, and I'm excited to launch this energy loan fund. From the farm to the shelf, I see renewable energy playing a bigger role in organic food,” said Bob Kirchoff, Organic Valley CEO.“Organic Valley is already helping to protect the environment through organic farming practices, and now they re going one step further by supporting the introduction of renewable energy projects for their farmer members,” said Blake Jones, volunteer board chair of Clean Energy Credit Union. “In addition to the environmental benefits, we re eager to help family farmers throughout the world to lower their energy costs.”The world is not short of examples of farmers innovating in the field of renewable energy. What's encouraging about Organic Valley's announcement is the idea of a national brand putting its marketing and financing weight behind such efforts and, hopefully, creating consumer demand that pushes the rest of the industry in this direction too.4. What does paragraph 1 indicate about going net zero for cattle farming?A It is not easy to achieve B. It is common in the UKC. It is an impractical goalD. It meets no challenges5. What is Organic Valley's tradition according to the text?A. Helping farm suppliersB. Using renewable energyC. Having a loan initiativeD. Making headlines annually6. What is Organic Valley's initiative mainly intended to do?A. Reform organic farming practicesB. Make use of environmental benefitsC. Help farmers decrease energy costsD. Shrink the group of farmer members7. What is the author's attitude towards Organic Valley's initiative?A. WorriedB. DoubtfulC. AmbiguousD. PositiveCYou must have read "The Tortoise and the Hare(《龟兔赛跑》)" when you were younger. So which animal are you? The tortoise or the hare? Do you rush around trying to do things as quickly as possible? Or do you deal your work at a slow , but steady(稳定的)pace? Whether you approach life like the tortoise or the hare can make a difference in the results you'll see.Some will say that you should avoid being like the hare. After all. he was overconfident and finally lost the race. You mayalso have heard teachers say from time to time that "haste makes waste”. But what does that mean? Most people think it meant that the faster you do something,the more likely it is that you'll make mistakes. Many teaches wantyouto approach your schoolwork thoughtfully and carefully.But does haste always make waste? Not necessarily ! Some people are able to work quickly while also maintaining(保持)a high level of quality in all that they do. Recent research, however, is making the idea of haste making waste seem more believableResearchers found that the brain changes into a special mode(模式)when forced to make rapid decisions. Overall, there appears to be a trade-off between speed and correctness. As the brain makes decisions more quickly, those decisions are usually built on less information, which often leads to a greater likelihood of mistakes.When you approach things like the tortoise. you methodically and steadily work towards your goal. You might not arrive there first, but then again you might! In any case, you're likely to make fewer mistakes and you might just enjoy the journey more than the bare.Goals are great to work towards, but often the achievements aren't what we remember. In the end, the most meaningful and important parts of our lives are the journeys we went on , not the destination we reached. So be the hare when you have to, but always remember that the slow and steady journey is what you’ll remember and treasure the most.8. Why does the author mention the story in the first paragraph?A. To introduce the topic.B. To show its popularity.C. To suggest its importance.D. To advise readers to read it.9. For what purpose do teachers often say “haste makes waste to students?A. To ask them not to waste their time.B. To tell them it is OK to make mistakes.C. To ask them to avoid making silly mistakes.D. To tell them they should check their schoolwork.10. What is Paragraph 4 mainly about?A. How the brain collects the information it needs.B. When the decision made by the brain is correct.C. Why the quickly-made decision is often unwise.D. What the relationship between lime and results is.11. Which of the following may the author agree with?A. Finishing the race is often a victory for everyone.B. Joy is found not in finishing an activity but in doing it.C. The journey to every destination starts with a small step.D. A destination is important because it guides us on the journey.DIn the old days, when you had to drive to a movie theater to get some entertainment, it was easy to see how your actions could have an impact（影响）on the environment. After all, you were jumping into your car, driving across town, coughing out emissions（产生排放）and using gas all the way. But now that we're used to staying at home and streaming movies, we might get a littleproud. After all, we're just picking up our phones and maybe turning on the TV. You're welcome. Mother Nature.Not so fast, says a recent report from the French-based Shift Project. According to "Climate Crisis: The Unsustainable Use of Online Video", digital technologies are responsible for 4% of greenhouse gas emissions, and that energy use is increasing by 9% a year. Watching a half-hour show would cause 1. 6 kilograms of carbon dioxide emissions. That's like driving 6. 28 kilometers. And in the European Union, the Eureca project found that data centers（where videos are stored）there used 25% more energy in 2017 compared to just three years earlier, reports the BBC.Streaming is only expected to increase as webecome more enamored ofour digital devices（设备）and the possibility of enjoying entertainment where and when we want it increases. Online video use is expected to increase by four times from 2017 to 2022 and account for 80% of all Internet traffic by 2022. By then, about 60% of the world's population will be online.You're probably not going to give up your streaming services, but there're things you can do to help lessen the impact of your online use, experts say. For example, according to Lutz Stobbe, a researcher from the Fraunhofer Institute in Berlin, we have no need to upload 25 pictures of the same thing to the cloud because it consumes energy every time. If instead you delete a few things here and there, you can save energy. Moreover, it's also a good idea to stream over Wi-Fi, watch on the smallest screen you can, and turn off your Wi-Fi in your home if you're not using your devices.12. What topic is the first paragraph intended to lead in?A. The environmental effects of driving private cars.B. The improvements on environmental awareness.C. The change in the way people seek entertainment.D The environmental impacts of screaming services.13. What does the underlined phrase become more enamored of" in paragraph 3 probably mean?A. Get more skeptical of.B. Become more aware of.C. Feel much crazier about.D. Get more worried about.14. What can we infer about the use of streaming services?A. It is being reduced to protect the planet.B. Its environmental effects are worsening.C. It is easily available to almost everyone.D. Its side effects have drawn global attention.15. Which of the following is the most environmentally-friendly?A. Watching downloaded movies on a mobile phone.B. Downloading music on a personal computer.C. Uploading a lot of images of the same thing.D. Playing online games over mobile networks.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

The study was led by professor of psychology Jean M. Twenge at San Diego State University (SDSU).To research this link, Twenge, along with colleagues Gabrielle Martin at SDSU and W. Keith Campbell at the University of Georgia, dealt with data from the Monitoring the Future (MtF) study, a nationally representative survey of more than a million U. S. 8th-, 10th-, and 12th-graders. The survey asked students questions about how often they spent time on their Phones, tablets and computers, as well as questions about their face-to-face social interactions and their overall happiness.On average found that teens who spent more time in front of screen devices — playing computer games, using social media, texting and video chatting — were less happy than those who invested more time in non-screen activities like sports, reading newspapers and magazines, and face-to-face social interactions."The key to digital media use and happiness is limited use," Twenge said. "Aim to spend no more than two hours a day on digital media, and try to increase the amount of time you spend seeing friends face-to-face andexercising — two activities reliably linked to greater happiness."Looking at historical trends from the same age groups since the 1990s, it's easy to find that the increase of screen devices over time happened at the same time as a general drop-off in reported happiness inU. S.teens. Specifically, young peopled life satisfaction and happiness declined sharply after 2012. That's the year when the percentage of Americans who owned a smartphone rose above 50 percent. By far the largest change in teens' lives between 2012 and 2016 was the increase in the amount of time they spent on digital media, and the following decline in in-person social activities and sleep.4. Which method did Twenge's team use for the study?A. Calculating students' happiness.B. Asking students certain questions.C. Analyzing data from a survey.D. Doing experiments on screen time.5. How does the author develop the finding of the study in paragraph 3?A. By making a comparison.B. By giving an example.C. By making an argument.D. By introducing a concept.6. What is the purpose of the last paragraph?A To draw a conclusion from the study.B. To offer some advice to the readers.C. To prove social activities' importance.D. To support the researchers' finding.7. Which of the following can be the best title for the text?A. Quitting Phones Equals HappinessB. Screen Time Should Be BannedC. Teens' Lives Have Changed SharplyD. Screen-addicted Teens Are UnhappierCThe air is thin and we have to rest several times on the shore hike from camp. To our left, snow-covered mountains disappear into clouds that seem almost close enough to touch. On the plain in front of us, we can justmake out a herd of graceful animals. This is why we stay here.Tibetan antelopes live mainly on the plains of Tibet. Watching them move slowly across the green grass, I'm struck by their beauty. I'm also reminded of the danger they are in. They are being hunted illegally for their valuable fur.My guide is Zhaxi, a villager from Changtang. He works at the Changtang National Nature Reserve. The reserve is a safe place for the animals and plants of northwestern Tibet. To Zhaxi, protecting the wildlife is a way of life. “We're not trying to save the animals,” he says. “Actually, we're trying to save ourselves.”In the 1980s and 1990s the population of Tibetan antelopes dropped by more than 50 percent. Hunters were shooting antelopes to make money. Their living places were becoming smaller as new roads and railways were built.In order to save Tibetan antelopes, the Chinese government placed them under national protection. Zhaxi and volunteers watched over the antelopes day and night to keep them safe from attacks. Bridges and gates were added to let the antelopes move easily and keep them safe from cars and trains.The measures were effective. The antelope population has recovered and in June 2015, the Tibetan antelope wasremovedfrom the endangered species list. The government, however, does not intend to stop the protection program since the threat to the Tibetan antelope has not yet disappeared. Only when we learn to exist in harmony with nature can we stop being a threat to wildlife and to our planet.8. What can we learn from Zhaxi's words in paragraph 3?A. Protecting the animals can make money.B. Protecting the animals is protecting ourselves.C. He is not fond of protecting the animals.D. The reserve is only safe for wild animals.9. What is mainly talked about in paragraph 4?A. Why hunters hunt Tibetan antelopes.B. Why antelopes' living places changed.C. Why antelopes' number dropped greatly.D. Why the 1980s and the 1990s are unusual.10. What does the underlined word “removed” in the last paragraph probably mean?A. Deleted.B. Changed.C. Migrated.D. Recognized.11. What might be the future condition of Tibetan antelopes according to the last paragraph?A. They will be over-populated.B. They will be a threat to man and other wildlife.C. They will be on the endangered species list again.D. They will be in harmony with nature and humans.DDogs are often referred to as “man's best friend”. But MacKenzie, a four-pound Chihuahua (奇瓦瓦狗), who was named winner of the 2020 American Hero Dog competition, is making the world a better place for humans and animals alike. Often called the “Oscars for dogs”, the award recognizes dogs who make great contributions to society.This year's competition attracted over 400 competitors from across the country. While all were impressive, it was tiny MacKenzie who won the judges' hearts. Born at a rescue shelter in Hilton, New York, in 2013, she had a cleft palate (腭裂) that required her to be tube fed for the first year of her life. A life-saving operation, performed in 2014, gave her the ability to eat and drink independently, enabling the tiny dog to focus on doing what she loved most: taking care of others.The seven-year-old Chihuahua is now gainfully “employed” by the Mid Foundation, a Rochester, New York-based non-profit organization that shelters and cares for animals born with disabilities. MacKenzie's official job is “to provide love and care for baby rescue animals born with birth defects”. The Chihuahua is good at her job and hasnurturedmany different species-from puppies to kittens to turkeys, squirrels, birds and even a goat. She acts as their mother and teaches them how to socialize, play, and have good manners.In addition to her role as an animal caretaker, MacKenzie also has the important job of greeting the foundation's volunteers and friends. The incredible dog, who has lost her ability to bark, also visits area schools to help children understand physical disabilities in both animals and people. Her heart-warming and inspiring story makes MacKenzie worthy of America's top dog honor!12. What made MacKenzie American Hero Dog?A. Being man's best friend.B. Her struggle with disabilities.C. Rescuing animals with disabilities.D. Her contributions to a better world.13. What can we infer about MacKenzie from Paragraph 2?A. Her growth path was not easy.B. She was deserted by her owner.C. She was operated on at two years old.D. She still needs taking care of by others.14. What does the underlined word “nurtured” in Paragraph 3 mean?A. Trained.B. Comforted.C. Tended.D. Abused.15. Which can be a suitable title for the text?A. MacKenzie—The Most Hard-working DogB. MacKenzie—America's “Most Heroic Dog”C. Chihuahua—Inspiration of Positive EnergyD.

2021届汕头市东厦中学高三语文一模试题及答案解析
2021届汕头市东厦中学高三语文一模试题及答案解析一、现代文阅读（36分）(一)现代文阅读I(9分)阅读下面的文字，完成下面小题。
考察路遥一夜春雨过后，城市的空气中少了不少怪味道。
省委大院里鹅黄嫩绿，姹紫嫣红，小鸟在树丛中发出欢愉的啁啾。
这个天地里已经是一片春天的繁荣景象，天完全放晴了，东边的太阳正从一大片楼房后面吃力地爬起来。
乔伯年比往常提前一刻钟吃完早点，换了一双圆口黑斜纹布鞋，准备过一会就出门。
这时候，省委常务副秘书长张生民来了，说新闻记者马上就到。
乔伯年对他说：“为什么要让记者来？你赶快去打电话，让新闻单位不要派记者来！”秘书长在一刹那间愣住了，但他很快反应过来，他不敢违抗书记的指示，赶紧转身出去打电话。
张生民一路走，一路想：看来用老办法已经不能适应这位新书记的要求了，但怎样才能适应老乔的要求呢？作为省委常务副秘书长，多年来他已经习惯于一种传统的思路和传统的工作方法，而且前任书记对他的工作一直是很满意的。
唉，他现在不会工作了！接二连三地弄巧成拙！张生民打完电话，刚出了院子，就看见一溜小轿车鱼贯进入省委大院——这是市上的领导们来了。
他赶忙迎上去，把这些人领进了小会议室。
乔伯年进入小会议室时，所有的人都从沙发上站起来。
他和大家一一握了手，也没坐，立在茶几前说：“今天把同志们找来，不说别的事，咱们一块去坐一次公共汽车怎么样？”大家在一刹那间明白了：省委书记要深入基层了解情况，解决群众坐车难的问题哩。
张生民说：“为不惊动四方，请大家出去不要公开身份。
”张秘书长见省委书记赞同地点了点头。
他们先到一个就近的公共汽车站，准备坐四路公共汽车在解放大道六路口下车后，再换坐一趟电车。
此时正值早晨上班的高峰期，公共汽车站挤满了黑压压的人群。
街道两边，自行车像两股洪流，向相反的方向滚滚而去，并且在每一个十字路口形成了巨大的漩涡。
过了近十分钟，四路车还不见踪影。
市上的领导们也焦躁不安地向南面张望。
他们多么希望这该死的汽车早点来啊！此刻，他们专心致志地等车，已顾不得和省委书记说两句闲话，以掩饰这令人难堪和不安的局面。
