广东省六校2020届高三英语第二次联考试题[附答案]

一、现代文阅读（35分）（一）现代文阅读I（本题共5小题，19分）阅读下面的文字，完成1-5题。

①在公共生活中的“说理”是一种理性交流、表达看法、解释主张，并对别人可能有说服作用的话语形式。

说服就是运用语言来对具体的他人作劝说、解释、说明，以期对他们有所影响。

伊索寓言中有一则《太阳与风》的故事：太阳与风进行比赛，看谁能使穿着外套的行人脱掉外套。

风刮了又刮，但刮得越凶，那个行人就把外套裹得越紧。

然后太阳出来了，照在行人的身上，行人感到身体出汗了，就把外套脱了下来。

这个故事可以用作“说服强于强制”的寓言。

希腊哲学家芝诺对说服有相似的说法，他称说服是一只摊开的手掌，而不是一个攥紧的拳头。

说服是欢迎他人加入对话，不是企图限制他们有自己的看法，更不是威胁他们不准有自己的看法。

②说理通过说明和协商，而不是暴力或战争来解决人间可能出现的矛盾和冲突，并形成一种可以称之为“讲理”的文明秩序。

所有的战争和混乱都是在没有协商，无理可讲的情况下发生的；说理使得人类能够用摊开的手掌，而不是攥紧的拳头来相互交往，人类才得以进入文明社会。

然而，当下互联网中的说理常常被当作是攥紧拳头，而非摊开手掌的话语行为。

这样的“说理”便成为“占领话语阵地”“口诛笔伐”“论战”和向对方报以“投枪”和“匕首”。

这种“说理”观念令无数人深受其害而浑然不知。

③说理是发表意见，但“发表意见”并不就是说理。

任何表达看法的陈述，包括骂和谩骂，都可以说是“发表意见”，但并不是说理。

说理的“发表意见”必须包括两个部分：一个是“结论”（也称主张或看法），另一个是“理由”，结论是由理由来支持的。

当然，有理由支持的结论未必都确实或可靠，因此需要评估理由是否真的能充分支持主张。

④说理需要平等、理性地对待不同意见，并不只是出于说理者主观意愿的“宽宏”“宽厚”或“宽容”，而是由“说理”本身的话语特性决定的。

说理离不开价值判断，包括伦理和政治的判断，尽管它并不专门讨论伦理和政治。

In this blog, we will introduce five most attractive places that you can’t miss if you are planning to go for a travel in China!BeijingBeijing, the capital of China for over 850 years, is the first choice for many travellers. A perfect combination of classic elegance and modernity, it is the best Chinese destination to give you a better understanding of the country. You can wander around the Forbidden City to feel the dignity of the city; or you can walk along the criss-crossing hutongs and enjoy yourself in everyday local life.Xi’anIf you want to feel the history of China over the past 1,000 years, you can go to Beijing; however, if you want to experience the 5,000 years’ history of this ancient, oriental land, Xi’an is the best travel destination in China. As one of the four major capitals of ancient civilisation (together with Athens, Cairo, and Rome), Xi’an is the home of Chinese civilisation. The Silk Road starts from here, stretching through West China to the Mediterranean.GuilinGuilin, a peaceful city lying in the hilly south-western area of the country, is among the top Chinese destinations for its extraordinary natural scenery. The unique karst landscape with its four features, namely green hills, clear water, fantastic caves, and oddly-shaped rocks, makes it a famous tourist attraction.ChengduVisiting the lovely giant pandas must be on everyone’s to-do list when planning a tour of the best Chinese destinations. Many cities have zoos with space for pandas, but the best place to get close to them is Chengdu for sure! Visiting Chengdu is also a treat for food lovers. Jin li Street is a great place to have a taste of well-known Sichuan food. Besides, you can also enjoy the comfortable atmosphere.1．What can you do in Beijing?A．Enjoy the oddly-shaped rocks.B．Have a taste of Sichuan food.C．Walk around the Forbidden City.D．Learn the history of the Silk Road.2．If you are interested in natural landscapes, which destination is suitable for you?A．Beijing.B．Xi’an.C．Guilin.D．Chengdu. 3．What will be written in the following paragraph?A．Another attractive place in China.B．The introduction to karst landscape.C．Tips for travelling around the world.D．The contact information of a museum.It is a bright cold day in April and Paul Blachut is busy as usual. From behind the bar of a restaurant, he has a good view of the river. He can see that, along the shore, many visitors are cooling their feet in the river.Among those are a mother and her two teenage daughters. They’re standing on the edge of the riverbank, playing with an inflatable (充气的)tube when, suddenly, the girls lose their footing and are caught in the river’s current. It all happens so fast. The girls desperately grab on to the tube, which their mother is sitting in, dragging her into the river, too. Now all three are being carried away by the fast current.A bystander races to the restaurant and shouted for help. Despite having no lifesaving training, Blachut rushes to the riverbank, quickly pulling off his T-shirt. Then he jumps into the river. He doesn’t care about the cold; all he can think about is saving the women.As Blachut gets closer to them, he can tell that the mother seems to be in the most trouble; her head is now submerged. He recalls how a lifeguard saves people in a movie so he tries this, but in vain. Without hesitation, Blachut dives under the drowning woman, pushing her upward and using that momentum (冲力) to push her toward the shore. Then he dives into the current again, swims quickly downstream and manages to get hold of one of the teenagers, and get her out in the same way he did her mother. He is out of strength and luckily, the girl’s sister is helped out by someone else.Several onlookers express their admiration for Blachut following the incident, but he is modest about his role. “The whole rescue only took two or three minutes” he says today, adding that he is happy to have received high praise from his boss for his courage. Indeed, it was a job very well done.4．What might Blachut be?A．A visitor.B．A waiter.C．The boss.D．A lifeguard. 5．What happens to the mother of two teenagers?A．She loses her footing while playing.B．She is dragged into the river by accident.C．She jumps into the river to save her daughters.D．She loses control of the tube and flows with it.6．What is the key factor in this successful rescue?A．Blachut’s rich lifesaving experience.B．The method Blachut recalls in a movie.C．The slow speed of the river current.D．Blachut’s ability to make quickdecisions.7．In which section of a newspaper may the text appear?A．Health.B．Travel.C．Inspiration.D．Entertainment.“With the passing of Chinese scientist Yuan Longping, China and the world have lost one greatest agricultural scientists,” Kenneth Quinn, president of the World Food Prize Foundation, said. Quinn, also vice chairman of the Yuan Longping International Rice Development Forum, shared his memory of the “father of hybrid rice” in an interview with Xinhua on Sunday.Quinn first met Yuan in October 2004, when Y uan traveled to Des Moines in the U.S. state of Iowa to receive the World Food Prize. As they walked out of the airport , Quinn received a call and stepped aside to speak. When he turned back a minute or two later, he lost Yuan. “I had never before ‘lost’ a laureate(贵人),” he said. After a desperate search, he found Professor Yuan surrounded by a group of smiling graduate students from Iowa State University who so admired him that they wanted to take him off for a meal and conversation.Quinn admired Yuan as a teacher. “He always had time to answer questions and speak with young scientists and students. The American high school students we sent to his research center each year always returned filled with knowledge and a deep desire to learn more.”In Quinn’s eyes, Yuan was incredibly humble, never seeking fame, and focused only on hard work and results that could help lift people out of poverty. With a ‘down to earth’ attitude, Yuan greatly reduced hunger and provided farmers with surplus income through his discovery of hybrid rice.Learning of Yuan’s passing away on Saturday, Quinn issued a statement to send his deepest sympathy to Yuan’s family and colleagues in China, as well as his admirers across theworld. “Professor Y uan Longping, who was truly beloved in his country and by all of us who knew him, will be greatly missed. His legacy will provide inspiration to generations far into the future, in China and across the world,” Quinn said in the statement.8．How did Kenneth Quinn feel when he found Yuan in a group of students?A．Confused.B．Amazed.C．Annoyed.D．Frightened. 9．How did Yuan Longping deal with young people ?A．He cared about the development of the youth.B．He sent young students abroad for further study.C．He was too busy to answer the students’ question.D．He was generous to help young people out of trouble.10．What does the words “down to earth” mean in paragraph 4?A．Realistic .B．Stubborn C．Flexible D．Critical 11．What is the purpose of the text?A．To introduce the “father of hybrid rice”.B．To share the stories of Y uan Longping.C．To remember Professor Yuan LongpingD．To inspire the young to become a pioneer.Jason M. Allen was almost too nervous to enter his first art competition. Now, his award-winning image is stirring debates about whether art can be generated by a computer, and what, exactly, it means to be an artist.In August 2022, Allen, a 39-year-old game designer who lives in Pueblo West, Colorado, won first place in the “digital arts/digitally-operated photography” category at the Colorado State Fair Fine Arts Competition. His winning image, titled Théatre D’opéra Spatial, was made with Midjourney—an artificial intelligence system that can produce detailed images when fed written prompts (提示).Allen’s winning image looks like a bright cross between a classic and modern painting. It’s one of three such images he entered in the competition. Allen posted excitedly about his win on Midjourney’s Discord server on August 25, along with pictures of his three entries; it spread quickly on Twitter days later, with many artists feeling angry about Allen’s win because of his use of AI to create the image. “He just ‘pressed a few buttons to make a digital art piece’,” one Twitter user wrote. “We’re watching the death of art unfold before our eyes.”However, to get the final three images he entered in the competition, Allen said, he took over 80 hours. First, he played around with phrasing that led Midjourney to generate images of women in nice dresses and space helmets. Over time, with slight adjustments to his written prompts, he created 900 repeating processes of what led to his final three images. He gave the final touch to those three images in Photoshop. Then he ran the images through another software program called Gigapixel AI that can improve resolution (分辨率) and had the images printed at a local print shop.Allen is glad that the debate over whether AI can be used to make art is getting so much attention. “Rather than hating the technology or the people behind it, we need to recognize it’s a powerful tool and use it for good so we can all move forward,” Allen said.12．What do we know about Theatre D’opera Spatial?A．Its beauty is widely accepted.B．Its creation is an easy process.C．It shows the death of traditional art.D．It has caused a lot of arguments. 13．What did Allen do to create his entries?A．He searched for smart written prompts.B．He edited his final images in Photoshop.C．He fed Midjourney with famous paintings.D．He developed the software named Gigapixel.14．What is Allen’s attitude to the debate over Al-created art?A．Worried.B．Uncaring.C．Positive.D．Annoyed. 15．What might be the best title for the text?A．AI Beats Out Human Artists in the Art FieldB．AI Won an Art Contest and Artists Are AngryC．An Artist Wins State Fair Art Contest and LaughsD．The Artist From Pueblo West Is Defending His Work.Over the past years, countless studies conducted have shown the positive effects that laughing has on one’s physical and mental health. Are you ready to laugh more? Below you’ll find five ways to bring more laughter into your life.Smile more. Smiling is not laughing. 16 When you smile, happy changes begin to take place naturally, both internally and externally. In addition, you can think of smiling as a warm-up for laughing.Learn to laugh at yourself. Most of us take ourselves too seriously. 17Learning to laugh at yourself takes some of the pressure off. You can look for the funny side of things. When you’re upset about something, ask yourself “How is this situation funny?” Humor can even turn a negative into a positive.Share stories from the past. Do you remember one time in high school that you and your best friend wore false hair and matching clothes around your neighborhood? Or, how about when your best friend sat on a painted bench by accident? 18Take up something new. When you try something new — whether it’s to draw or learn to roller skate — your original attempts will likely be clumsy (笨拙的) and even ridiculous (荒谬的). 19 So taking up something new is likely to result in laughs.20 We are heavily influenced by the people we are with, so by hanging out with funny people, we can add more laughter into our days. That positive and silly energy will immediately rub off on (感染) us and it can cause us to want to feel happier and sillier throughout our days.A．That is funny.B．It has a lot of benefits.C．Follow funny people on Twitter.D．Surround yourself with funny people.E．These reminders can make us feel silly and childlike.F．For better results, think of a funny moment from the past.G．So our ability to find the humor in difficult situations can be limited.二、完形填空I can remember the first time it happened.

Which of the following books will you choose if you are interested in sports?A. We Came Here to ShineB. Nobody Will Tell You This but MeC. A Star Is BoredD. Fast GirlsBI enjoy throwing stuff away. I’d love to go full minimalism (极简主义), but my wife and two teenage kids do not share my dream of a house with almost nothing in it. I have tried. When the kids were little, I taught them my two favorite games –“Do We Need It?” and “Put It in Its Place”– and made them play every few months. Their enthusiasm never matched mine.If I’m going to be honest, my own tidying skills are not as great as I’d like. My “discarded” pileis never quite the trash mountain I want because I make up excuses for why things are useful. I consider this unhealthy. I want to be better at moving on.So, this time I found help –the classics for people like me: The Life-Changing Magic of Tidying Up, by Marie Kondo. Kondo’s commitment to her craft is astonishing. Her philosophy is only to keep things you love. Can I go full Kondo? I will try. One central idea is to clean by category. You start by collecting all clothes and gathering them together for consideration. It makes you rethink how you organize. Next, hold each item and ask if it brings you joy. This way you’re choosing what to keep. And that’s how I find myse lf with all my clothes on my bedroom floor. My wife walks by and gives me a look that says I’m nuts. She’s probably not wrong.Somewhere near the bottom of this chaos is my special jacket. I move through the pile: pants, shirts, suits and shoes. Then my la st category: jackets. I haven’t worn the thing in about 30 years. Somehow, it has survived. Now that I’m striving to follow Kondo – surely, its time has come?I hold it in my hand. There is a tear just below the collar that widens as I hold it. It’s litera lly falling apart. Will I ever wear it again? Not a chance. Does it feel good to wear? Does it bring me joy? Actually, yes. At this moment, my daughter walks in. She asks about the jacket. I tell her the story. She thinks I should keep it. It’s cool and unique and full of memories. She is arguing that nostalgia (怀念) is the very reason.I’m not entirely convinced by my daughter’s arguments. I believe in looking ahead, not backward. Nevertheless, sometimes it’s hard to let go. So I gently place the jacket on the “keep” pile.24. What does the underlined word “discarded” probably mean in Paragraph 2?A. adjustedB. reservedC. abandonedD. tidied25. What drives the author to read The Life-Changing Magic of Tidying Up?A. To learn how to categorize.B. To improve his tidying skills.C. To persuade his family members.D. To develop passion for minimalism.26. What is the attitude of the author’s family members toward minimalism?A. They don’t understand itB. They completely support it.C. They are strongly opposed to it.D. They are less passionate about it.27. What’s the best title for the text?A. Knowing when to let goB. Classifying what you loveC. Throwing worn-out clothesD. Keeping valuable possessionsCThe world’s biggest elect ric vehicle — a 45-ton mining dump trucknamed theeDumper —may have to give up its throne. The newcomer, powered with bothelectricity and a reserve of hydrogen fuel, is going tosteal that title as the largestelectric mining truck.London-based Anglo American is developing the beast of a machine— it weighs290 tons — as part of its sustainable mining vision. Theconceptual work is done,but U.K-based Williams Advanced Engineeringwill bring the truck to life. The ideais to replace the vehicle’s diesel engi ne (柴油机) with a high- power modular lithium-ion battery (锂电池). “We are delighted to be involved in this innovative andexciting project which shows the potential of battery technology that can adapt to increased demands, from automotive and motorsport to ‘heavy duty’ industrial applications,” Craig Wilson, managingdirector of Williams Advanced Engineering, said.While the eDumper — a mining truck used to move stones from the sides of mountains inSwitzerland —relies entirely on pure electricity and pure physics for power, the Anglo American truck will use both a lithium-ion battery and a hydrogen fuel cell (电池) module. Altogether, the new truck will have over 1,000 Kilowatt hours of energy storage.Hydrogen fuel is a clear fuel that produces only water as a by-product when consumed in a fuelcell. It’s typically produced from natural gas, nuclear power, or renewable wind and solar power. Adding hydrogen fuel cells to the vehicle’s battery will allow the truck to run for longer periods of time without rechargin g.There’s also a third type of power that comes into play with the Anglo American truck: kinetic (动力的) energy created through the process of regenerative braking (再生制动系统). When an electric vehicle — be it the Anglo American truck, or the eDumper —rolls down a hill, that movement creates electrical energy for the battery as you brake. The electric motors power the car through the battery’s stored energy, but can also become mini generators that return some energy back to the battery.After Anglo American finishes test trials with the truck, the firm will conduct studies to understand how the truck’s power units can be used to provide energy storage in other applications.28. What can be known about “the eDumper”?A. It weighs more than 290 tons.B. It is powered by hydrogen fuel.C. It will no longer be the largest electric truck.D. It will discourage buyers for being expensive.29. What can be inferred from Craig Wilson’s words?A. Battery technology is the key to updating vehicles.B. Battery technology is the basis of manufacturing trucks.C. The development of the lithium-ion battery is limited.D. The future of the lithium-ion battery is promising.30. What is the benefit of adopting hydrogen fuel cells?A. It can save a lot of money.B. Vehicles become more eco-friendly.C. It has no environmental impact at all.D. Vehicles no longer need to be recharged.31. According to paragraph 5, which of the following can be a feature of regenerative braking?A. Autonomous braking.B. Energy transformation.C. Simple operation.D. zero-carbon emission.DDreams, according to Carl Jung, reveal a certain amount of reality hidden during waking consciousness. In Jungian philosophy, the conflict and chaos experienced in dreams finally bring order to our lives. While Jung’s mystical theories are debatable, he was not mistaken about the importance of dreaming. A growing number of reports show that a continuous lack of dreaming is damaging our waking hours in many ways.This trend is causing damage to our immune and metabolic (新陈代谢的) systems, let alone theelectronic products that keep us up late at night are ruining our sleep patterns, which has long-term consequences on our memory system. One study showed that not allowing mice to have adequate amounts of REM (Rapid Eye Movement) sleep, the stage in which we dream, the mice couldn’t strengthen memories.You might think this is just a sleep problem, but dreaming is inseparable from our nighttime rest. We sleep in cycles (周期), each lasting about 90 minutes; in a sleep cycle, we go through non-REM sleep before hitting REM. As the night progresses, REM sleep periods increase in length while deep sleep (one of the stages of non-REM sleep) decreases. The longer we sleep, the more time we spend in REM, which is why we are often dreaming when waking up in the morning. If we sleep less than seven hours, however, it becomes harder to achieve this level of REM.The combination of sleeping and dreaming acts as an emotional stabilizer. We recover from emotional hurt faster when w e sleep and dream properly. However, we’re not getting enough sleep tocycle through the stages to take advantage of this natural circadian anti-depressant (抗抑郁剂)— dreams. Instead, we get depressed and turn to alcohol or medicines to get to sleep, which only makesthings worse because even one drink leads to late REM while anti-depressants promote deep sleep atthe expense of REM.We’re paying for this lack of dreaming in many ways. For example, a 2021 study stated that compared with quiet rest and non-REM sleep, REM promoted the formation of associative networksand the integration (整合) of unassociated information. V olunteers that experienced more REM sleepwere better equipped for solving problems requiring creative solutions.Rowan Hooper, the managing editor at New Scientist, writes that dreams that include an “emotional core” appear to be a main function of REM sleep and that we should look at sleep patterns as seriously as we do diet and exercise habits.32. What’s Car Jung’s view about dreams?A. They cause chaos.B. They damage immunity.C. They reveal secrets.D. They mirror reality.33. Why is the sleep process explained in paragraph 3?A. To show a dream mainly occurs during REM sleep.B. To prove the minimum sleep time should be seven hours.C. To prove dream problems and sleep problems are attached.D. To show people often dream when waking up in the morning.34. What conclusion can be inferred from paragraph 5?A. Dreaming promotes creativity.B. Dreaming helps fight depression.C. The brain still receives new information during REM sleep.D. The brain is paying the price for having more non-REM sleep.35. What’s the main idea of the passage?A. The importance of sleep lies in dreams.B. The absence of dreams is terrible for us.C. Dreaming patterns are more important than we realize.D. Dreaming has mystical power of strengthening memories.第二节（共 5 小题；每小题 2.5 分, 满分12.5 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。

广东省六校（东莞中学、广州二中、惠州一中、深圳实验、珠海一中、中山纪念）2024届高三上学期第二次联考英语读后续写题目:阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。

Police Outpost Lake is as far south as you can go in Canada. In fact, next to the lake are the protected wetlands, where songbirds, ducks, and Canada geese glided by on the breeze, touching down briefly on the water’s surface before flapping(振翅) their way back up into the sky.Standing at the lake’s edge, my cousin, Allan, and I cast our fishing lines separately onto the smoothasglass water. Down the shoreline was Allan’s father, my uncle Rick. He liked to fish alone, away from distractions, noise, and other people.Allan shouted, “Dad, where should I stand?”Uncle Rick pressed his finger to his lips, pointed to a shady spot by a large rock where he had cast his line and shook his head gently.“He wants us to be quiet or else we won’t catch any fish.”I whispered.“Why do I have to be so quiet?”asked Allan. “All those birds are making more noise than I ever could!”I ignored him, pulling back on my rod gently and squinting into the glare of the sun. Out of the corner of my eye, I caught a glimpse of a few great northern loons(潜鸟) gathering together not far from the shoreline. What were they doing there? Loons usually travel alone, but here were five of them in a cluster. Maybe it was a family? Just then one loon, making a loud painful cry, swam away from the group, toward me.“Allan! e here. Now!”Allan laid his fishing rod down on the dirty sand, darting toward me.“e here. Take a look at that loon. It’s swimming toward us, not far away from us. It’s trying to get our attention.”The loon finally stopped in the shallow water near shore, not ten feet away from us. It was so close that we could see its round red eyes. Strangely, the bird’s wings were held tight against its body.Wading into the water and getting closer to the loon, we both saw a fishing line wrapped tightly around its neck and a shiny red hook(鱼钩) in its body. Left like this, the loon couldn’t fly or fish or survive. It was asking us to help! 注意：1.续写词数应为150 词左右；2.请按如下格式在答题卡的相应位置作答。
