湖南省湖南师范大学附属中学2023-2024学年高三上学期第三次月考英语试题

湖南省湖南师范大学附属中学2023-2024学年高三上学期第三次月考英语试题学校:___________姓名:___________班级:___________考号:___________一、阅读理解Cannes(戛纳)is a place that offers lots of different ways to spoil yourself. During the Cannes Film Festival in May, nothing changes, except that there are more people doing this, and that they talk about film. Here’s a guide to what you should do during the festival, both film-related and not.Hotel Intercontinental CarltonThe film festival is a busy time for Cannes. The best way to appreciate the crowds might be having a dinner on a terrace(露天平台). Head to the Hotel Intercontinental Carlton and wander the lobby to take it all in. If you’re lucky you might be able to secure a table in the restaurant. Dress to impress or you won’t stand a chance of getting in.Cinema de la PlageThroughout the Cannes Film Festival, one of the best places to soak up some of the wonderful atmosphere is the open-air Cinema de la Plage at Mace beach. If you haven’t secured a ticket in advance for a seat, there’s no need to worry. You can spread a blanket out on the ground, open up your pre-prepared picnic, and enjoy the movie.Marché ForvilleThe Marché Forville is a must-see for any visitor to Cannes and a foodie’.s delight. On most days, vendors sell home-made fruits and vegetables as well as local specialties to eat for lunch. But don’t go on Mondays, unless you want to browse for bargains, as that’s when the flea market is on instead.La CroisetteLa Croisette is the most famous walk in Cannes and is listed under the cultural inventory of France itself. Stroll the whole length, stop for a coffee, and end your walk by sitting on one of the free blue chairs along the way while taking in the view. It is also a great place to admire Cannes’ sculptures.1.What is probably the intention of the text?A.To introduce French culture.B.To present dining locations.C.To publicize a film festival.D.To suggest tourism activities.2.Which place best suits people who enjoy shopping?A.Hotel Intercontinental Carlton.B.Cinema de la Plage.C.Marché Forville.D.La Croisette.3.What can be expected in Cannes during the festival?A.Attending fashion shows.B.Watching movies outdoors.C.Tasting imported farm produce.D.Experiencing sculpture production.Coming into the freshman year at Paul College, Sansa was concerned about her ability as an individual to make an impact on such a large community, for it was never hard for her to stand out from peers in high school. Luckily, each first-year student in Paul College takes part in what is called the First-year Innovation and Research Experience, commonly referred to as the FIRE Program, an extracurricular project assigned by the institution. She was able to forge invaluable connections with her fellow students and their peer advisor who had so much first-hand experience with what they all were going through.The biggest highlight of her freshman year was working alongside her FIRE team on a Grand Challenge Project, in which every FIRE team competed against one another in the Undergraduate Research Conference. Each team had to create a unique product that tackled one of the five following real-world problems: “Water is Life”, “Food”, “Threats from Cyberspace”, “Medical Breakthroughs”, and “Addictive Society”. Her team addressed the growing issue of “Addictive Society”. Doing research, collecting facts and organizing discussions or even debates were a huge amount of work before they went to vie with other teams.After weeks of tireless preparation, their collective efforts bore fruit at the Undergraduate Research Conference. They earned a spot in the final round of the conference, where they competed against the top team from each of the other Grand Challenge groups. They were so overcome with pride when they were finally announced as the overall first-place team at the college!If it hadn’t been for her group’s determination, excellent teamwork and their awesome peer advisor Hayley, they would not have been able to accomplish everything they did. This experience would be instrumental in her future.4.What do we know about Sansa from paragraph 1?A.She performed quite well in high school.B.She was much more experienced than her college schoolmates.C.She applied for the FIRE Program.D.She had trouble with her freshman year.5.How did each team compete against one another?A.By providing facts.B.By creating products.C.By organizing debates.D.By challenging each other.6.What does the underlined phrase “vie with” in paragraph 2 probably mean?A.Contest against.B.Give way to.C.Break up with.D.Make up with.7.What is probably Sansa’s biggest gain from the FIRE Program?A.Financial benefits.B.Academic reputation.C.Good relationships.D.Competitive opponents.When Jason Allen submitted his “Th éâtre D’.opéra Spatial” into the Colorado StateFair’s fine arts competition, the print was an immediate hit, defeating 20 other artists in the “digitally manipulated photography” category to win the first-place blue ribbon and a $ 300 prize.Allen’s piece offers a clear example of how rapidly AI-generated art has advanced. Trained on billions of internet images, the systems have decisively pushed the boundaries of what computers can create.But it has also sparked a massive debate over the meaning of art, with Allen facing accusations that he had been deceiving with something he asked a machine to create.Text-to-image tools like DALL-E 2 and Midjourney have quickly increased in sophistication and have become one of the hottest topics in AI. They can generate not just fake people, objects and locations but mimic entire visual styles.But AI-generated art has been criticized as automated plagiarism (剽窃), because it relies on millions of ingested art pieces that are then parroted (机械地重复) together. It has also fueled deeper fears: blurring the boundaries of reality or interfering with human art.Allen said his art piece shows people need to “get past their denial and fear” of a technology that could give rise to new inventions and reshape our world. “The AI,” he said,“is a tool, just like the paintbrush is a tool. Without the person, there is no creative force.”Jessica Hair, a 25-year-old receptionist at a doctor’s office who won third place in the competition, said she did not feel as if Allen had acted unfairly and had no hard feelings about his win.Hair said her “Judge, Jury, Executioner”, which depicts a tuxedoed skeleton on a golden throne surrounded by skulls, took 15 hours to create with a stylus (触屏笔) on an iPad Pro. But Allen’s piece took time, effort and subjective judgment, too, and “how do we qualify what is and isn’t art?” she said.8.Which of the following statements can be inferred from the text?A.It is the first time in history that an AI-generated work has won an arts competition.B.Advances made in computer art are not as rapid as the public believes them to be.C.Computer-produced works have more success in some art forms than in others.D.People’s acceptance of computer-produced art pieces can vary considerably. 9.According to the text, why is AI-generated art facing severe criticism?A.Because it will ultimately overtake human art in the future.B.Because it will lead to a sharp decrease in human creativity.C.Because it purely uses existing art pieces as its subject matter.D.Because the technical standard of its output is extremely low.10.What was Allen’s reaction to people’s criticism?A.He fought back like a soldier.B.He kept silent like a victim.C.He persuaded like a promoter.D.He lost heart like a failure.11.What is Jessica Hair’s attitude towards Allen’s award-winning piece?A.Supportive.B.Critical.C.Cautious.D.Skeptical.The streets, sidewalks and roofs of cities all absorb heat during the day, making some urban areas across the United States up to 6 degrees Fahrenheit hotter than rural ones during the day—and 22 degrees F hotter at night. These “urban heat islands”can also develop underground as the city heat spreads downward, beneath the surface. And basements, subway tunnels and other underground infrastructure also constantly bleed heat into the surrounding earth, creating hotspots. Now the underground heat is building up as the planet warms.According to a new study of downtown Chicago, underground hotspots may threaten the very same structures that emit the heat in the first place. Such temperature changes make the ground around them expand and contract (收缩) enough to cause potential damage. “Without anyone realizing it, the city of Chicago’s downtown was deforming,” says the study’s author Alessandro F. Rotta Loria, a civil and environmental engineer at Northwestern University.The findings, published in Communications Engineering, expose a “silent hazard (危险)” to civil infrastructure in cities with soft er ground — especially those near water — Rotta Loria says. “There might have been structural issues caused by this underground climate change that happened, and we didn’t even realize,” he adds. While not an immediate or direct danger to human lives, this previously unknown effect highlights the impacts of a lesser-known component of climate change.Similar to climate change above the surface, these underground changes occur over long periods of time. “These effects took decades, a century, to develop,” Rotta Loria says, adding that elevated underground temperatures would likewise take a long time to dissipate (逐渐消失) on their own.But other researchers interviewed for this story all say this wasted energy could also be recycled, presenting an opportunity to both cool the subsurface and save on energy costs. Subway tunnels and basements could be updated with technologies to recapture the heat. For example, water pipes could be installed to run through underground hotspots and pick up some of the heat energy.12.What can we learn about the “urban heat islands”?A.They can develop underground structures.B.They are impacted by global warming.C.They can destroy the ground around.D.They only exist in the United States.13.Why does Alessandro F. Rotta Loria mention “silent hazard” in paragraph 3?A.To discuss structural issues.B.To categorize climate change.C.To explain underground heat.D.To emphasize the neglected reality.14.What will the author probably write about in the paragraph that follows?A.The future of tunnels and basements.B.The reusing approaches of heat energy.C.The cost of maintaining structures.D.The evolution of underground environment.15.Which of the following can be the best title for the text?A.Warming Underground, Weakening SurfaceB.A Silver Lining of Global WarmingC.Urban Silent Islands in the MakingD.A Silent Crisis in Downtown Chicago二、七选五Including children in the farming lifestyle has many benefits. Sure, it is nice to have the additional help with chores, but it also fosters so much growth, sending our kids down a good path towards who they will someday become. It is possible that our children will grow up to lead lives that do not include farming. 16Through caring for farm animals, kids learn that in life others often come before self.17 It doesn’t matter if we don’t feel like it or if we are sick and tired. What matters is that we take care of the animals that take care of us and do so in a timely manner.18 If the work on a farm does not get done, the operation fails. It takes discipline and commitment to get down to business every day, and seeing this in action will give kids a good work attitude. They will know and understand that nothing good comes easy and that they have to work to survive. 19 Functioning as part of a productive team will surely be playing a crucial role sooner or later in all walks of life.Additionally, farming teaches patience. 20 It’s especially true for the animals. Cattle will be difficult to control. Horses will run away when you try to catch them. Goats will kick over that bucket of hard-earned milk. A rooster will decide you got too close to his hens and give you a run for your money. In spite of all that, kids will learn to be patient and take things easy.There may not be any instant reward, but in the long-term kids will see the benefit of all their efforts during those hard days.A.Fairly often, things do not go your way.B.Kids also learn to be grateful to animals.C.In the meantime, they learn to work with others.D.Teamwork is no longer a significant skill to develop and use.E.Animals need to be fed and cared for before we get to sit down and relax.F.Kids are also able to comprehend the value of hard work through farm life.G.What they learn on a farm, however, can be instrumental in their future lives.三、完形填空27.A.could B.should C.would D.might 28.A.also B.again C.only D.instead 29.A.responded B.claimed C.updated D.expressed 30.A.odd B.general C.novel D.complicated 31.A.closed B.black C.plain D.blank 32.A.lesson B.blame C.curse D.ban 33.A.open B.click C.use D.function 34.A.refreshing B.crashing C.connecting D.running 35.A.advocate B.tolerate C.appreciate D.understand四、用单词的适当形式完成短文阅读下面短文,在空白处填入1个适当的单词或括号内单词的正确形式。
