2022-2023学年重庆市第一中学校高三3月月考英语试题
2022-2023学年重庆市第一中学校高三3月月考英语试题1. Wedding Traditions and Superstitions (迷信)Good luck and bad luckHey, brides, hide a sugar cube into your glove according to Greek culture, the sugar will sweeten your union. In English tradition, Wednesday is considered the “best day” to marry. Ancient Romans studied pig insides to determine the luckiest time to marry. Rain on your wedding day is actually considered good luck, according to Hindu tradition. For good luck, Egyptian women pinch (掐) the bride on her wedding day. Ouch!It’s got a ring to itDiamonds set in gold or silver became popular as engagement rings among wealthy Venetians toward the end of the 15th century. A pearl engagement ring is said to be bad luck because its shape echoes that of a tear. Snake rings dotted with ruby eyes were popular wedding bands in Victorian England, which symbolized elernity. Aquamarine is said to ensure along, happy marriage.Show off at a partyThe Roman goddess Juno rules over marriage, the hearth and childbirth, hence the popularity of June weddings. Princess Victoria established the tradition of playing Wagner’s “Bridal Chorus” during her wedding in 1858. The bride stands to the groom’s left during a Chris tian ceremony, while the Catholic tradition of “posting the banns” to announce a marriage originated as a way to ensure the bride and groom were not related.Fashionable loreIn Asia, wearing robes with embroidered cranes symbolizes loyalty for the length of a marriage. In Korea, brides wear bright hues of red and yellow to take their vows (宣誓). In Denmark, brides and grooms traditionally cross-dressed to confuse evil spirits.Food and familyIn South Africa, the parents of both bride and groom traditionally carried fire from their hearths to light a new fire in the newlyweds’ hearth. Legend says single women will dream of their future husbands if they sleep with a slice of groom’s cake under their pillows.1. Which of the following may bring good luck to newlyweds?A.A sugar cube. B.A slice of groom’s cake.C.A pig’s insides.D.A pearl engagement ring.2. Which wedding tradition originated from religion?A.The popularity of June weddings.B.Women guests pinching the bride.C.The bride standing to the groom’s right.D.“Posting the banns” to announce a marriage.3. What may Asian newlyweds find socially acceptable at their weddings?A.Lighting a new fire.B.Brides dressed in red and yellow.C.Playing Wagner’s “Bridal Chorus”.D.Cross-dressing brides and grooms.2. I remember going to the British Museum one day to read up the treatment for some slight illness — hay fever, I thought it was. I got down the book, and read all I came to read: and then, I began to casually study diseases generally. Turning over the pages, I came to typhoid fever, read the symptoms and discovered that I had it. I was wondering what else I had got, and St. Vitus’s Dance turned up, which I thought I also had. So I determined to go through it thoroughly and so started alphabetically (照字母顺序排列的): ague I had, just in the acute stage. Cholera I had with severe complications; and diphtheria I seemed to have been born with.I sat and considered. What an interesting case I must be from a medical point of view! What a learning materia l I should be to a medical class! Students would have no need to “walk the hospitals”, if they had me. I was a hospital in myself. All they need do would be to walk around me, and, after that, take their diploma!I went to my doctor, who is an old friend of mine. I thought I would do him a good turn by going to him now. “What a doctor wants”, I said, “is practice. He will get more practice out of me than out of 1,700 of his ordinary, commonplace patients, with only one or two diseases each.” He said: “Well, what’s the matter with you?” I said, “I will not take up your time, with telling you what is the matter with me. But I will tell you what is not the matter with me. I have not got a housemaid’s knee (髌前囊炎). Everything else, however, I have got.” And I tol d him how I came to discover it all.He felt my pulse, looked at my tongue, and talked about the weather as usual, all for nothing. Then he wrote out a prescription, folded it up and gave it to me, and I put it in my pocket and went out. I did not open it. I took it to the nearest chemist’s and handed it in. The man read it and then handed it back. I read the prescription. It ran:“beefsteak, every 6 hours.ten-mile walk every morning.bed at 11 sharp every night.And don’t stuff up your head with things you don’t understand.”1. Why did the author go to the British Museum the other day?A.To see a doctor.B.To study medicine.C.To go to an exhibition.D.To seek for a treatment.2. How did the author find himself affected with various “illnesses”?A.Through a routine check-up.B.By reading the medical book.C.By consulting with experts.D.Through self-imagination.3. What can we infer from paragraph 2?A.The writer was put in charge of a hospital.B.The writer could treat his diseases on his own.C.The writer was refusing professional medical training.D.The writer considered himself valuable to medical study.4. Which of the following can be the main idea of the text?A.It’s never too late to learn.B.A disease known is half cured.C.An apple a day keeps the doctor away.D.Don’t trouble troubles until trouble troubles you.3. The highlights of every World Cup are the impossible goals, especially the arc (弧线) ball goals. It’s breathtaking to watch. Every spin (旋转) of the ball moves air across the surface, pushing it into a bend.When a soccer ball flies, the air forms a layer around the surface of the ball. As the balls pins, it changes the direction of the air to one side, says John Bush, an applied mathematician at MIT. This air pushes the ball in the opposite direction. The player starts with a strike on the outside of his right foot, which hits the left side of the ball, starting a clockwise spin. It throws the air off to the left, and the force created by the air leaving the ball pushes it to the right, explains Bush. Thus, a ball spinning to the right (that’s clockwise) will also are towards the right. This force is called the Magnus Effect.It helps the goalkeepers, because they see uniform curvature (曲度) when players are taking bending s hots at them. If they can pick up the spin right, it’s going to be the same amount of curvature, and they know where to put their hands. This is partly why players are much more likely to take bending shots during free kicks when goalkeepers can’t see thei r kicks quite as well because of the wall of defenders. If a ball isn’t spinning, it does something called knuckling, where the air turns the ball to one side in random directions, causing it to bounce in-the air unpredictably. “It’s usually achieved when a player manages a sharp, fast touch of the ball, typically right on the air valve where the ball is most firm.” say a Bush. Its lack of spin kept the goalkeeper from being able to predict where itwas going until it was too late. All the goalkeepers tremble before the kicker that can shoot this kind of soccer ball.1. What is the Magnus Effect according to the text?A.The force applied to a spinning ball. B.The theory proposed by John Bush.C.The direction opposite to a player’s strike.D.The goal scored with a bending ball.2. Why do soccer players prefer to take bending shots during free kicks?A.Because they can change the ball’s curvature.B.Because they can take bending shots more easily.C.Because they can get a cover from their team males.D.Because they can trick their way past the opposing defenders.3. Which shot might be the most predictable for goalkeepers?A.A free-kicks hot.B.A fast shot without spinning·C.A shot with a unique curvature.D.A bending shot without defensive blocking.4. What’s the writer’s purpose of writing this text?A.To explain how to score an arc ball goal.B.To uncover the secret of blocking a goal.C.To analyze the principle of a bending ball.D.To introduce a theory of applied mathematics.4. Aimed exclusi vely at Stanford’s information technology (IT) community, the Elimination of Harmful Language Initiative (EHLI) sought to address potentially “harmful language” on Stanford websites. The guide reportedly listed 10 categories of offensive languages: violent, person-first, institutionalized racism etc. Among the discouraged words and terms were “manpower” because it “strengthens male-dominated language;” “walk-in” because “walk” trivializes (轻视) people with disabilities; and “whitepaper” because white “assign s value connections based on color(white=good);” It also suggests not using the phrase “long time no see” because it “was originally used to mock (模仿,嘲弄) Indigenous pc op les and Chinese who spoke pidgin (混杂语) English” because it is seen as disrespectful as it radicalize s people of Asian origin as forever opposite‘others’.”Stanford recommended the alternatives “workforce” for “manpower,” “drop-in” for “walk-in,” “position paper” for “whitepaper,” “I haven’t seen you in so long!” for “long time no see”. It alsoincluded “American” because it implies “that the U.S. is the most important country in the Americas,” excluding dozens of other nations. The alternative offered was “U.S. citizen.”Dr. Jay Bhattacharya, a professor at Stanford School of Medicine, said in an interview with Fox News. “It doesn’t actually encourage respect for people. It just makes people think w has wrong with great universities like Stanford,”. The great anger has also been evident online. Amid the chorus of angry comments, Stanford chose to shut down the EHLI website. Chief Information Officer Steve Gallagher said the initiative actually sought to be more inclusive but admitted that they missed the mark. “The feedback was broadly viewed a so opposition to inclusivity. It is for this reason that we have taken down the EHLI site.” Gallagher said.1. Who was EHLI intended for?A.Teaching staff at Stanford.B.Students applying for Stanford.C.Hackers attacking Stanford’s websites.D.Netizens getting into Stanford’s IT community.2. Which of the expressions might be encouraged by EHLI?A.An African American. B.A person with COVID-19.C.A U.S. human resource manager. D.A victims hot dead on campus.3. What does the underlined phrase “missed the mark” mean?A.Start losing scores. B.Su cceed in one’s guess.C.Fail to achieve one’s goal.D.Have a bad, long-lasting effect.4. Why was the EHLI site taken down?A.Because it drew a lot of feedback. B.Because it damaged Stanford’s benefit.C.Because it was hard to put into practice. D.Because it went against its initialintention.5. What Are Great Books?There’s no end to the making of books. Nor does there seem to be any end to the making of lists of “great books”. 1 What I will mention may not be all there are, but they are the o nes I’ve found most useful in explaining my choices over the years.Great books are probably the most widely read.They’re not bestsellers for a year or two. They are lasting bestsellers. Gone With The Wind has had relatively few readers compared to the plays of Shakespeare. It would be reasonable to estimate that Homer’s Iliad has been read by at least 25,000,000 people in the last 3000 years. 2Great books arc popular, non-academic.They’re not written by specialists about speciaties. Whether they be phi losophy or science, or history or poetry, they treat of humans not academic problems. 3 But the great books can be considered elementary in the sense that they treat the elements of any subject matter. They’re not related to one another as a series of textbooks, graded in difficulty.4They have more ideas per page than most books have in their entirety. That is why you can read a great book over and over again and never exhaust its contents. They can be read at many different levels of understanding. Obvious examples are Gulliver’s Travels, Robinson Crusoe and Odyssey. Children can read them with enjoyment, but fail to find there in all the beauty and significance which delight an adult mind.Great books are the most instructive.Great books contain what cannot be found in other books. Whether you ultimately agree or disagree with what they say, these are the primary teachers of mankind. 5 It’s almost unnecessary to add that the great books are the most influential. In the tradition of learning, they have been most discussed by readers who have also been writers.6. For 6-year-old Junie, meeting a firefighter was a truly interactive experience. In a TikTok video posted by his mom, the little boy, who’s ______ , got to feel a firefighter’s entire uniform and equipment while asking the man questions.The clip opens with a shot of a firefighter going down on his ______ in front of a fire truck.

Recent development has made possiblemachines that print, cook, and serve foods o n a mass scale. And the industryisn’t stopping there.Food productionWith a 3D printer, a cook canprint complicated chocolate sculptures and beautiful pieces for decoration on awedding cake. Not everybody can do that — it takes years of experience, buta printer makes it easy. A restaurant in Spain uses a Foodini to”re-create forms and pieces” of food that are “exactly thesame,” freeing cooks to complete other tasks. In another restaurant, allof the dishes and desserts it serves are 3D-printed, rather than farm to table.SustainabilityThe global population is expectedto grow to 9.6 billion by 2050, and some analysts estimate that food productionwill need to be raised by 50 percent to maintain current levels. Sustainabilityis becoming a necessity. 3D food printing could probably contribute to thesolution. Some experts believe printers could use hydrocolloids from plentiful renewables like algae and grass to replace the familiar ingredients. 3D printing can reduce fuel use and emissions. Grocery stores of the future might stock “food” that lasts years on end, freeing upshelf space and reducing transportation and storage requirements.NutritionFuture 3D food printers couldmake processed food healthier. Hod Lipson, a professor at Columbia University,said, “Food printing could allow consumers to print food with customizednutritional content, like vitamins. So instead of eating a piece of yesterday’sbread from the supermarket, you’d eat something baked just for you ondemand.”ChallengesDespite recent advancements in3D food printing, the industry has many challenges to overcome. Currently, mostingredients must be changed to a paste before a printer can use them,and the printing process is quite time-consuming, because ingredients interactwith each other in very complex ways. On top of that, most of the 3D foodprinters now are restricted to dry ingredients, because meat and milk productsmay easily go bad. Some experts are skeptical about 3D food printers, believingthey are better suited for fast food restaurants than homes and high-endrestaurants.(1)What benefit does 3D printing bring to food production?A . It helps cooks to create new dishes.B . It saves time and effort in cooking.C . It improves the cooking conditions.D . It contributes to restaurant decorations.(2)What can we learn about 3D food printing from Paragraphs 3?A . It solves food shortages easily.B . It quickens the transportation of food.C . It needs no space for the storage of food.D . It uses renewable materials as sources of food.(3)According to Paragraph 4, 3D-printed food ________.A . is more available to consumersB . can meet individual nutritionalneedsC . is more tasty than food in supermarketsD . can keep all the nutrition in raw materials(4)What is the main factor that prevents 3D food printing from spreading widely?A . The printing process is complicated.B . 3D food printers are too expensive.C . Food materials have to be dry.D . Some experts doubt 3D food printing.(5)What could be the best title of the passage?A . 3D Food Printing: Delicious New TechnologyB . A New Way to Improve 3D Food PrintingC . The Challenges for 3D Food ProductionD . 3D Food Printing: From Farm to Table19. 阅读理解Failure is probably the most exhaustingexperience a person ever has. There is nothing more tiring than not succeeding.We experience this tiredness intwo ways: as start-up fatigue and performance fatigue. In the former case, we keepputting off a task because it has either too boring or too difficult. And thelonger we delay it, the more tired we feel.Such start-up fatigue is veryreal, even if not actually physical, not something in our muscles and bones.The solution is obvious though perhaps not easy to apply: always handle themost difficult job first.Years ago, I was asked to write102 essays on the great ideas of some famous authors. Applying my own rule, Idetermined to write them in alphabetical, never letting myself leaveout a tough idea. And I always startedthe day’s work with the difficult taskof essay-writing. Experience proved that the rule works.Performance fatigue is moredifficult to handle. Though willing to get started, we cannot seem to do thejob right. Its difficulties appear so great that, however hard we work, we failagain and again. In such a situation, I work as hard as I can-then let theunconscious take over.When planning EncyclopaediaBritannica , I had to create a table of contents based on the topics of itsarticles. Nothing like this had ever been done before, and day after dat I keptcoming up with solutions, but none of them worked. My fatigue became almostunbearable.One day, mentally exhausted, Iwrote down all the reasons why this problem could not be solved. I tried toconvince myself that the trouble was with the problem itself, not with me.Relived, I sat back in an easy chair and fell asleep.An hour later, I woke upsuddenly with the solution clearly in mind. In the weeks that followed, thesolution which had come up in my unconscious mind provided correct at everystep. Though I worked as hard as before, I felt no fatigue. Success was now asexciting as failure had been depressing.Human beings, I believe musttry to succeed. Success, then, means never feeling tired.(1)People with start-up fatigue are most likely to .A . delay tasksB . work hardC . seek helpD . accept failure(2)What does the author recommend doing to prevent start-up fatigue?A . Writing essays in strict order.B . Building up physical strength.C .Leaving out the toughest ideas.D . Dealing with the hardest task first.(3)On what occasion does a person probably suffer from performance fatigue?A . Before starting a difficult task.B . When all the solutions fail.C . If the job is rather boring.D . After finding a way out.(4)According to the author, the unconscious mind may help us .A . ignore mental problemsB . get some nice sleepC . gain complete reliefD . find the right solution(5)What could be the best title for the passage?A . Success Is Built upon FailureB . How to Handle Performance FatigueC . Getting over Fatigue: A Way to SuccessD . Fatigue: An Early Sign of Health Problems20. 阅读理解A scientist working at her lab bench and asix-old baby playing with his food might seem to have little in common. Afterall, the scientist is engaged in serious research to uncover the very nature ofthe physical world, and the baby is, well, just playing…right? Perhaps,but some developmental psychologists have argued that this “play” is morelike a scientific invest igation than one might think.Take a closer look at the babyplaying at the table. Each time the bowl of rice is pushed over the table edge,it falls in the ground---and, in the process, it belongs out important evidenceabout how physical objects interact; bowls of rice do not flood in mid-sit, butrequire support to remain stable. It is likely that babies are not born knowingthe basic fact of the universe; nor are they everclearly taught it. Instead,babies may form an understanding of object support through repeated experimentsand then build on this knowledge to learn even more about how objects interact.Though their ranges and tools differ, the baby’s investigation and thescientist’s experiment appear to share the same aim, overall approach , and logic.Some psychologists suggest thatyoung children learn about more than just the physical world in this way---thatthey investigate human psychology and the rules of language using similarmeans. For example, it may only be through repeated experiments, evidence gathering,and finally overturning a theory, that a baby will come to accept the idea thatother people can have different views and desires from what he or she has, forexample, unlike the child, Mommy actually doesn’t like Dove chocolate.Viewing childhood developmentas a scientific investigation throws on how children learn, but it also offersan inspiring look at science and scientists. Why do young children andscientists seem to be so much alike? Psychologists have suggested that scienceas an effort ---the desire to explore, explain, and understand our world---issimply something that comes from our babyhood.

重庆市第一中学2020-2021学年高一下学期第一次月考英语试题
重庆市第一中学2020-2021学年高一下学期第一次月考英语试题学校:___________姓名:___________班级:___________考号:___________一、阅读选择Jackie Chan is arguably the biggest non-Hollywood movie star in the world. Chan has been very helpful in creating the film type of kung-fu comedy, which transformed the Hong Kong film industry. Inspired by legendary film clowns such as Buster Keaton and Harold Lloyd, Chan has invented his own unique film style, combining humor and stunt (特技).Jackie Chan was born on April 7, 1954 in Hong Kong. He was the only child of Charles and Lee-Lee Chan. Though the family lived in a flat in the Victoria Peak district, they didn’t own it — Charles worked as a cook for the French ambassador, while Lee-Lee was the housekeeper.Chan attended Nah-Hwa Primary School on Hong Kong Island, often spending his money on food, fighting on the way to school with other children. He was not academically bright, failing to pass Primary 1 as his peers moved on to Primary 3. Charles decided to send the seven-year-old boy to the Peking Opera School. Walking in with his father, Chan saw children somersaulting and playing with swords and sticks. He recalls that he felt like entering Disneyland. He would never return to an academic education. Though he speaks seven languages, he still cannot read or write with great —proficiency and has someone else write his scripts for him.As an amazing artist, Chan experienced strict training at the Peking Opera School, where he studied acting, singing, dance and martial arts for 19 hours a day for a period of 10 years. Being something of a miracle, he was introduced to public performance early. At eight he was cast in Big and Little Wong Tin Bar, with the great Taiwanese star, Li Lihua, as his mother. Chan’s extraordinary athleticism and unique stunt-work quickly brought him a lead role in Master with Crocked Fingers.After several attempts to break into American cinema from the Hong Kong market, Chan finally met with success, widening his heroic characters and making them more international. 1.What led to Jackie Chan’s success?A.His unique kung-fu film style.B.Receiving training for legendary film clowns.C.His acting in Hollywood.D.Being born into a kung-fu family.2.Why did Jackie Chan’s father send him to the Peking Opera School?A.Because his father was very fond of Peking Opera.B.Because his father didn’t have enough money to support him.C.Because Jackie Chan wasn’t doing well at the primary school.D.Because Jackie Chan show great interest in public performance.3.What is the main idea of the last two paragraph?A.How Jackie Chan became an international star.B.The main films of Jackie Chan.C.The development of the Hong Kong film market.D.The different roles that Jackie Chan has played.Who doesn’t want to live life in style? Life is like a road on which you never get a chance to return, and is not a very long road either. So we should try to live life to the fullest and enjoy every bit of it.Every individual has unique likings and preferences, and all of us try to live the lives that suit us best. The world is like a painting cloth on which different people with different races, different languages, and different cultural backgrounds interact. But among these, the arts provide an easy and natural way for people to connect.People with a knack for the arts usually discover it in childhood. But art isn’t only for the talented; it can help everyone grow. Those with a strong artistic background are often more energetic, and more successful in all fields of life. Art widens the range of a person’s life.Painting is one of the most popular art forms. Those who are interested in taking it up as a career need to go through extensive training to get familiar with the various styles. Professional painters often host art exhibitions, with art lovers from all over the world coming to see and buy their creations. Sometimes the paintings are sold at high prices.Performing arts are equally popular and admired. Dance, instrumental music, drama and so on require unusual artistic talent as well as a long period of education and training before audiences start to applaud the performances. But anyone with some artistic sense can make art part of his/ her life, and benefit from it.4.People should make the most of life because .A.life is difficult but enjoyable timeB.life is valuable and ordinaryC.life is too short to be wastedD.life is like a road full of tomorrows5.What’s the main idea of Paragraph 2?A.Different people have different lifestyles.B.Different peoples have different cultures.C.Art can make people happier.D.Art can connect people together6.The underlined word “knack” in Paragraph 3 possibly means “”.A.character B.abilityC.power D.favour7.What is the passage mainly about?A.How great artists make a living by selling their works.B.How to live a unique and colorful life.C.How the arts contribute to people’s lives.D.How much performing arts have to do with talent and education.German artist HA Schult is an unusual artist who uses trash (废物) to make sculptures. “We are living in the time of garbage,” says Schult. “I created a thousand sculptures of garbage. They are a mirror of ourselves.” Here, Schult was talking about his 1,000 trash sculptures in the form of humans. He first exhibited them in 1996 in the western German state of North Rhine-Westphalia.“They are social sculptures,” he explains. “They are not only sculptures for the eyes. They are sculptures to spread the idea that we live in a time of garbage.” So far, Schult’s social sculptures have been on show in Par is, in Moscow’s Red Square, on the Great Wall of China, and in the desert next to the Pyramids of Giza near Cairo.HA Schulfs work is unforgettable. Although his work has had a big influence on the art world, Schult remains modest (谦虚的) about his creations: “Artists have to learn every time. We are not important. All that counts is the time in which we are living.”Trash art has been around for years. But it seems that only the popular artists are regarded as true artists when working with trash. W hy can’t common people be considered artists whenthey use the same things and change them into some form of personal art? Maybe it’s because we all have our own preset ideas of what art is and isn’t, or whom artists are or should be.You can be an artist like Schult if you try. Look at used metal cans. What might be done with them? Imagine them in any number of new uses, or imagine them simply as an art form. What about boxes or clothing? Boxes can usually serve as new storage containers and houses for pets. And clothing? Imagine taking old clothes and turning them into hats or hanging organizers.8.What do we know about Schult’s sculptures?A.They served as garbage containers.B.They reflected environmental problems.C.They were first shown in Paris, France.D.They were to raise economic awareness.9.HA Schult’s artistic works also get the message across that an artist must .A.be socially responsibleB.be as modest as possibleC.make garbage recyclableD.take different kinds of artistic forms10.Which of the following is the best title for the text?A.Could You Be a Trash Artist?B.What Are Social Sculptures?C.Do You Know about Trash Art?D.How Can We Deal with Used Cans?二、七选五Ways to Strengthen Your BrainpowerWant a healthier, sharper brain? It’s easier than you think to achieve improved cognition (认知) and memory. Try these simple tips to power up your brain!1. Play ping-pong.11.Researchers have found that in players older than 50, ping-pong improves brain health by activating specific neurons (神经元), and shows promise in preventing dementia (an illness that affects the brain and memory, and makes you gradually lose the ability to think and behave normally).2. Close your eyes.Research has found that closing your eyes while recalling an event could help you remember details 23 percent more accurately.12.It’s thought that once visual distractions are removed, your brain focuses more efficiently.3. Shake your body.Anew study has found that regular aerobic (有氧的) exercise can actually increase the size of your hippocampus — the part of your brain that helps you learn and remember.13.4. Find your sleep sweet spot.Getting a good nig ht’s sleep is the best thing you can do for your brain long term.14.The National Sleep Foundation recommends seven to nine hours of shut-eye per night for adults ages 18 to 64, and seven to eight hours for adults 65 and older.5.15.Make a point to regula rly ask yourself, “What if everything went right instead of wrong?” Positive thinking can actually activate your brain’s physical ability to adapt and change. Former President Jimmy Carter, 91, who responded to his recent cancer diagnosis with “optimism an d determination,” is a great example of this.A.How does it work?B.Look on the bright side.C.Hang out with friends and family.D.It improves your mood and clears out your mind.E.So whether it’s dancing, jumping or running, it’s good for your brain.F.If you want to sharpen your brain, you have to focus your attention on yourself.G.Table tennis has long been praised for its ability to improve attention and concentration.三、完形填空I love old people. Two of my best Mends are eighty-nine. I never understood it, 16 for some reason I’ve always been 17 to older people much more than children. I have such fond 18 of sitting with my grandfather before he died. We used to 19 him once a week, talk to each other for an hour or so, and then I leave.

重庆市第一中学校2022-2023学年高三下学期4月月考英语试题
重庆市第一中学校2022-2023学年高三下学期4月月考英语试题学校:___________姓名:___________班级:___________考号:___________一、阅读理解In 15 years, parkrun has grown from one event in London to 1,800 free, weekly, timed 5km runs around the world. Here are our favorites…BUSHY PARK, RICHMOND, LONDONBefore 2004, no one had heard of parkrun. But thanks to Paul Sinton-Hewitt CBE, on 2 October that year, the royal park held its first free run event. Starting with just 13 runners on its first day, the part-grassy, part-footpath route now holds the UK’s record number of entrants for a parkrun. It’s pretty fast and flat and the scenery doesn’t disappoint either. PORTRUSH, NORTHERN IRELANDWhen we say off the beaten track, we mean it. That’s because there’s not a footpath, track or even a park in sight-just sand. Bounding down a beach may be a bit of a killer workout for your calves, but it certainly offers a unique experience, completing 5km with the backdrop of waves crashing against the shore and a mind-blowing view of Dunluce Castle and the Giants Causeway.ASHTON COURT, BRISTOL, ENGLANDIf you’re a bit of a whizz when it comes to a 5km, this might be just the challenge you’re looking for. With a 2.5 km uphill start, this will really get those legs and lungs working hard. You’ll be rewarded at the turning point with fantastic views over Bristol and the promise of a downhill stretch back to the finish. The route runs along tarmac and stone paths, making the course suitable all year round.KANGAROO ISLAND, AUSTRALIAIt’s there in the title — wildlife is buult right in. Travelling down under this year? Head to Australia’s third-largest island for a 5km adventure trail. This jaw-dropping out-and-back course follows footpaths along the coastline, so you should be able to hop to the finish line in pretty good time, as long as you don’t get distracted by the wallabies, koalas, seals and kangaroos. Just allow time to get there, as it’s a 45-minute ferry ride from the mainland port of Cape Jervis.1.Which parkrun appeals to those who look for a fast and flat course?A.BUSHY PARK, RICHMOND, LONDON.B.PORTRUSH, NORTHERN IRELAND.C.ASHTON COURT, BRISTOL, ENGLAND.D.KANGAROO ISLAND, AUSTRALIA.2.Why should you plan to arrive early for the KANGAROO ISLAND parkrun? A.Warming up exercise is required.B.The parkrun is remotely located in the mainland.C.The distance is beyond the standard 5km.D.It takes time to reach the island via boat. 3.What do these parkruns have in common?A.They are all held monthly.B.They all feature scenic routes.C.They all take place along the coastline.D.They all offer an uphill start.I first heard of what is now known as Aten-Egypt’s own Pompeii back in December 2019. I was speaking with Zahi Hawass, the famous former head of Egyptian antiquities, on the sidelines of Egypt’s World Youth Forum. I was interested to hear about the latest work in Egyptian archaeology. But from my 16 years in the Middle East, I’m always a bit tired of archaeologists who sell their site as “the most important ever” or findings that “change our understanding” of a civilization. But it was not what Dr. Hawass had discovered that interested me. At that point, his team had not yet broken ground. What interested me was the team itself. For the first time, Dr. Hawass was leading an all-Egyptian team where every role was filled by an Egyptian national.For more than a century, western archaeologists have been the ones making “discoveries” in Egypt, the Levant and Mesopotamia. Even in modern joint Arab-international digs, I would watch as foreign archaeologists almost always got the credit, while their local partners would seem less important. One major reason for this gap is institutional and financial: western archaeologists have big-name universities and funds behind them, while Egyptian and other Arab archaeologists often have to pay for their own tools.The fact that Egyptians were now setting out to uncover more about their own archaeological heritage jumped out to me as an important story to tell. Unfortunately, the pandemic prevented me from joining Dr. Hawass and his team when they started excavations in 2020. When I finally arrived at their excavation sites in November 2022, I met passionate young Egyptian specialists, who expressed the hope of one day becoming university professors to pass on their knowledge and experience to the next generation of Egyptians.What I was witnessing was more than Egyptians gaining a renewed sense of dignity and reclaiming a past that was often told by others. It was a story of the many future Atens to be discovered by the all-Egyptian teams and archaeologists being inspired by this dig. 4.What do we know about Dr. Hawass from paragraph one?A.He likes boasting about his discovery.B.He made a ground-breaking discovery in 2019.C.He is the most famous archaeologist in Egypt.D.He led a team entirely composed of Egyptians.5.Why are western archaeologists mentioned in the second paragraph?A.To criticize their cooperation.B.To emphasize their cultural superiority. C.To highlight their advantages.D.To praise their contributions. 6.Which of the following can best describe the young Egyptian specialists?A.Inspired and motivated.B.Inexperienced and untrained. C.Humble and honest.D.Flexible and adaptable.7.Which of the following is the best title for the article?A.Western vs. Local Archaeologists.B.A Discovery Bigger than Archaeology. C.The Dignity of Egyptian Archaeologists.D.The Latest Discovery in Archaeology.The main reason not to ban ChatGPT in schools is that, to be frank, it’s not going to work. Sure, a school can block the ChatGPT website on school networks and school-owned devices. But students have phones, laptops and any number of other ways of accessing it outside of class. (Just for kicks, I asked ChatGPT how a student who was determined to use the app might break a schoolwide ban. It came up with five answers, all totally reasonable, including using a VPN to disguise the student’s web traffic.)Some teachers have high hopes for tools such as GPTZero, a program built by a Princeton student that claims to be able to detect A.I.-generated writing. But these tools aren’t reliably accurate, and it’s relatively easy to fool them by changing a few words, or using a different A.I. program to paraphrase certain passages.A.I. chatbots could be programmed to watermark their outputs in some way, so teachers would have an easier time spotting A.I.-generated text. But this, too, is a flimsy defense. Right now, ChatGPT is the only free, easy-to-use chatbot of its level. But there will be others, and students will soon be able to take their pick, probably including apps with no A.I.fingerprints.Even if it were technically possible to block CharGPT, do teachers want to spend their nights and weekends keeping up with the latest A.I. detection software? Several educators I spoke with said that while they found the idea of ChatGPT-assisted cheating annoying, policing it sounded even worse. “I don’t want to be in an adversarial relationship with my students,” said Gina Parnaby, the chair of the English department at the Marist School. “If our mindset approaching this is that we have to build a better mousetrap to catch kids cheating, I just think such a perspective is misguided, because the kids are going to figure something out.”Instead of starting an endless game of whack-a-mole against an ever-expanding army of A.I. chatbots, here’s a suggestion: For the rest of the academic year, schools should treat ChatGPT the way they treat calculators-allowing it for some assignments, but not others. Then, over the summer, teachers can modify their lesson plans-replacing take-home exams with in-class tests or group discussions, for example-to try to keep cheaters at bay. 8.Which of the following best describes ChatGPT?A.An app to detect A.I.-generated writing.B.An A.I. chatbot capable of generating text.C.A tool used to monitor students’ activity.D.A program made to assist with cheating.9.Which of the following can best replace the underlined word in paragraph 3? A.Spotless.B.Weak.C.Secure.D.Troublesome. 10.What can we infer from paragraph 4?A.Gina prefers prevention to detection.B.Some teachers favour using A.I. detection software.C.ChatGPT has caused concern among most educators.D.Some teachers hesitate to invest time in A.I. detection software.11.What is the purpose of the writing?A.To promote the wide use of ChatGPT in schools.B.To argue that ChatGPT should be banned in schools.C.To discuss the benefits and drawbacks of ChatGPT in schools.D.To convince schools to take a realistic attitude towards ChatGPT.Among the many ecological disasters that terrify us today, one that only a handful of people have considered as sufficiently terrifying is the loss of the bats in our church tower. According to “The Darkness Manifesto” (Scribner), by the Swedish ecologist Johan Eklf, most churches in southwest Sweden had bat colonies back in the nineteen-eighties, and now most of them don’t.Light pollution, his research suggests, has been a major reason: “District after district has installed modern floodlights to show the architecture it’s proud of, all the while the animals-who have for centuries found safety in the darkness of the church towers and who have for 70 million years made the night their home-are slowly but surely vanishing from these places.”The difference between light and dark is, in a way, arbitrary: what counts as light and what as darkness depends on what wavelengths we can make out. But the nocturnal (夜间活动的) world gives rise to creatures, equipped with large-pupilled and infrared-sensitive eyes, that see what we cannot and that, under cover of darkness, act as we can only imagine.We learn, for instance, of the ghost moths, a species in which the adult males appear in fields in twilight, floating weirdly as they signal to the females-only to mate once and then fall to the ground dead. Though Eklf tells us that these creatures are threatened by the confusing presence of artificial light and that moths play a crucial role as pollinators (“something of invaluable importance for keeping our ecosystem undamaged and thriving”), what one recalls is the sad fate of their couplings.Nor are bugs and birds alone affected by the light; so are plants, and so are humans. Our eyes adapt badly to darkness, and our night vision-which is activated by the pigment protein rhodopsin (视紫红质)-takes a long while to turn on. By now, cities such as Singapore and Hong Kong are so brightly lit that their inhabitants scarcely call on night vision at all, and, as their rhodopsin becomes unnecessary, they may well create people in later generations who, in even middling darkness, are as blind as bats.12.How has light pollution affected bats in southwest Sweden?A.Bats have had nowhere to stay.B.Bats have adapted to well-lit environment.C.Bats have moved away from the church towers.D.Bats have become endangered. 13.Which of the following can best describe nocturnal creatures?A.They are sensitive to different wavelengths of light.B.They are only active during the daytime.C.They are not affected by light pollution.D.They are unable to see in darkness.14.What does the writer want to tell us by the example in paragraph 4?A.The arbitrary nature of light and dark.B.The beauty and tragedy of the ghost moths.C.The threat that nocturnal creatures face.D.The importance of nocturnal creatures. 15.How does the writer sound in the last paragraph?A.Highly critical of the local government.B.Alarmed by the impact of artificial light. C.Curious about the effects of light pollution.D.Admiring of the adaptability of bats.二、七选五Chances are you already know a social butterfly at school.

A◆ Welwitschia mirabilisTitle: the world’s most resistant plantIt’s not pretty to look at, but welwitschia mirabilis is unique. It consists of only two leaves and a strong stem with roots. Two leaves continue to grow and the stem thickens and can grow to be almost 2 meters high and 8 meters wide. Its lifespan is 400 to 1,500 years. It can survive up to five years with no rain. The plant is said to be very tasty either raw or baked in hot ashes.◆ Dionaea muscipulaTitle: the Venus Fly TrapDionaea muscipula is the most famous carnivorous(肉食性的) plant due to the active and efficient nature of its unique trap. It may be famous, but it’s also threatened. It produces a short leaf that forms two sides of a trap. Each side contains some sensitive hairs. When it is touched two to three times, the trap will shut in less than a second, fast enough to catch flies and other insects. The leaf, once closed, produces some enzymes(酶) that slowly dissolve the insects and supply the plant with food.◆ Rafflesia arnoldiiTitle: the world’s largest flowerRafflesia arnoldii, the largest flower in the world, is an exotic and rare plant. The flower is 3 feet across and weighs 15-24 pounds. However, you wouldn’t want to grow it in your garden. In a rainforest-type environment, it gives off a most unpleasant smell, which is somewhat like rotten meat. This is why it is often called the Corpse Plant by some natives of Indonesia where it comes. Its flowers only last for three days to a week.◆ Euphorbia obeseTitle: the Baseball PlantEuphorbia obese is known as the Baseball Plant. Over-harvesting by plant collectors for its interesting and curious appearance has severely reduced the wild population. However, it has become very common now. By growing euphorbia obese in large numbers, many gardens have been working to ensure that the plants being traded and sold among plant collectors are not wild plants.21. From the passage, we know that __________.A. welwitschia mirabilis is very beautifulB. dionaea muscipula is famous for its trapC. rafflesia arnoldii feels like rotten meatD. euphorbia obese can be used as baseball22. According to the passage, rafflesia arnoldii __________.A. shuts its trap two or three times in one second.B. gives off a special smell to attract flies and insectsC. smells bad in a hot and wet environmentD. has a big flower, a strong stem and two leaves23. Plant collectors like euphorbia obese because __________.A. it looks strangeB. it tastes deliciousC. it can be planted in the gardenD. it is worth a big fortuneBThe tough challenge of a six-month, 3,200-kilometer walk across the South Pole, in the long darkness of the Antarctic winter when temperatures can fall to -90℃, proved irresistible to the experienced British explorer Sir Ranulph Fiennes.Fiennes’s hero, Captain Robert Falcon Scott, wrote “great God, this is an awful place” when he reached the South Pole a century ago, before freezing and starving to death with his team on the return journey.That journey was made in summer. Nobody before has attempted to cross the pole in winter. In a statement, Fiennes said, “This will be my greatest challenge to date. We will stretch the limits of human endurance. ”However, Fiennes could not explain why anyone should consider such a venture, still less a man aged 68 who has survived cancer, heart surgery and the loss of most of the frozen fingertips on one hand. “It’s what I do,”he said, looking slightly puzzled at the question.Fiennes, the world’s greatest living explorer, according to the Guinness Book of Records — was the first to cross the Antarctic continent unsupported; the first to cross both polar ice caps; and the first to travel across the globe from pole to pole.Fiennes admitted his wife, Louise, and their six-year-old daughter were not thrilled. “But I’ve never done anything else; it’s how I earn my living. And you’re much more likely, statistically, to die on the roads than on the polar ice,” he said.After training in the Swedish Arctic in a relatively balmy -40℃, Fiennes’team will set sail from London on Dec.6 on a South African research ship. The ice trek will begin on Mar.21, the spring equinox(春分) that marks the official start of the polar winter, from the Russian base of Novolazareskaya. Fiennes and his five team members must then climb more than 3,000 meters on to the inland plateau, walk for several hundred kilometers using an ice tractor to pull all the supplies and equipment they need, descend another 3,000 meters and finally reach the Ross Sea. If they reach Captain Scott’s old base at McMurdo Sound by the spring equinox six months later, they will still have to wait for months until the sea ice backs off enough for their ship to collect them.24. Fiennes is going on this expedition because__________.A. it is something he always does as a careerB. he wishes to inspire his familyC. he wants to travel with his wife and daughterD. he hopes to improve his health25. The underlined word in Paragraph 7 probably means “__________.”A. warm and pleasantB. cold and harshC. tough and unbearableD. agreeable and relaxing26. According to the article, Fiennes’ expedition will__________.A. begin at an Antarctic base of SwedenB. involve climbing and going down a high plateauC. start and finish exactly at the two spring equinoxesD. finish in a few weeks after the ship arrives27. Fiennes is attempting to cross the South Pole__________.A. on the same route as Captain Scott’sB. by himself during the winter monthsC. by ice tractor for most of the tripD. on foot during the worst tripCTwo musicians from Germany are using robotic equipment to add sounds to their performances. The two-man band performs with a robot that can play several musical instruments at the same time. The robot can sound like a guitar, keyboard, drum or other percussion instrument. When performing, members of the band provide many of the sounds, but others are controlled by a computer. Once connected to wires and set up, instruments can play on their own.One of the instruments was created from a long, self-turning wooden stick that sits on top of a microphone stand. The stick contains long strings. They are tied on each end. The strings are connected to a small wooden ball. As the stick turns, the ball hits a block on the floor, creating a sound.The two-man band, called Joasihno, recently performed at the South by Southwest Conference and Music Festival in Austin, Texas. They describe their electronic sound as “psychedelic(迷幻的) machine” music. “Actually, we call it a psychedelic robot orchestra,” said Cico Beck, one of the creators of the group.The group’s other member, Nico Siereg, says playing in an experimental band with robots is not the same as playing in a traditional one. “It’s a little bit different because you also have in mind that there are machines playing around you, so there’s no reaction from them,” he said. But Siereg said that in some ways, the robots actually help him improve his performance. Since the self-playing instruments are programmed, he sometimes feels freer to center on what he is playing, and at times to even play without preparation.The musician says he can imagine similar technology having a greater influence on many different kinds of music in the future. “Technology is like a very important tool that even, very often, it’s also a very important part of inspiration,” he said. But he also expressed hope that “real music won’t die.”In addition to performing recently in Texas, Joashihno has been busyputting on shows in Europe and in Canada. The band hopes its high-tech music “experiment” will keep reaching new people and pleasing the ears of its fans.28. According to the first paragraph, the robotic equipment __________.A. is operated by a wooden stickB. serves as a whole bandC. fuctions as musical instrumentsD. is battery-powered29. What does Nico Siereg think of playing music with robots?A. It is better than playing with human being.B. It is just a pity that the robots cannot respond to him.C. It has a negative effect on his performance because robots distract him.D. It is strange for him to have some machines playing around him.30. What can we learn from the passage?A. Robots will replace musical instruments.B. This new style of performance has become popular around the world.C. One member of the band doesn’t think playing with robots is real music.D. The machines are programmed to create many sounds.31. What is the best title for the passage?A. Real Music Won’t DieB. Adding New Blood to Traditional MusicC. High Technology Is Applied to MusicD. Robots Will Wipe Out Human BeingsDThe secret to eating less and being happy about it may have been found years ago — by McDonald’s. According to a new study from Cornell University’s Food and Brand Lab, small non-food rewards — like the toys in McDonald’s Happy Meals — stimulate the same reward centers in the brain as food does.The researchers, led by Martin Reimann, carried out a series of experiments to see if people would choose a smaller meal if it was paired with a non-food item.They found that the majority of both kids and adults chose a half-sized portion when combined with a prize. Both options were priced the same.Even more interesting is that the promise of a future reward was enough to make adults choose the smaller portion. One of the prizes used was a lottery ticket (彩票), with a $10, $ 50 or $100 payout, and this was as effective as a tangible gift in persuading people to eat less.“The fact that participants were willing to substitute part of a food item for the mere prospect of a relatively small monetary award is interesting,” says Reimann. “One explanation for this finding is that possible awards may be more emotionally inspiring than certainty awards. The uncertainty of winning provides added attraction and desirability through emotional ‘thrills’. The possibility of receiving an award also produces a state of hope — a state that is in itself psychologically rewarding.” In other words, there’s a reason why people like to gamble.How might this knowledge be used to help people eat more healthily?One possibility is a healthy option that offers the chance to win a spa weekend. Or maybe the reward of a half-sized portion could be a half-sized dessert to be claimed only on a future date. That would get you back in the restaurant — and make you eat a little less.32. What do we learn about McDonald’s inclusion of toys in its Happy Meals?A. It may throw light on people’s desire to find a secret.B. It has proved to be key to McDonald’s business success.C. It appeals to kid’s curiosity to find out what is hidden inside.D. It may be a pleasant way for kids to reduce their food intake.33. What is the finding of the researchers led by Martin Reimann?A. Reducing food intake is not that difficult if people go to McDonald’s more.B. Most kids and adults don’t actually feel hungry when they eat half of their meal.C. Eating a smaller portion of food does good to the health of kids and adults alike.D. Most kids and adults would choose a smaller meal that came with a non-food item.34. What is most interesting in Martin Reimann’s finding?A. Kids preferred an award in the form of money to one in the form of a toy.B. Adults chose the smaller portion on the mere promise of a future award.C. Both kids and adults felt satisfied with only half of their meal portions.D. Neither children nor adults could resist the temptation of a free toy.35. What can we infer from Martin Reimann’s finding?A. People should eat much less if they wish to stay healthy and happy.B. More fast food restaurants are likely to follow McDonald’s example.C. We can lead people to eat less while helping the restaurant business.D. More studies are needed to find out the influence of emotion on behavior. 第二节(共5小题;每小题2分,满分10分)Moving into a new home in a new neighborhood is an exciting experience. Of course, you want to make sure that you become an accepted and valuable part of your new neighborhood.
