Here are some of the museum’s most moving moments.The Olympic ParkThe journey through the Olympic Museum begins in the Olympic Park, an 8,000-square-meter outdoor area in front of the museum overlooking Lake Geneva and theAlps. The park contains artwork and sculptures that show respect to the world of sport.The first Olympic SymbolThe “Olympic Rings” flag was designed by Coubertin in 1913. The rings represent the five continents that participate in the Olympics: Africa, Asia,America,AustraliaandEurope. The six color1 s include at least one color1 that is represented on the flag of every country.The StadiumsThe stadiums that host the Olympic Games are as much of a celebration of design as the games are a celebration of sportsmanship. Guests can explore plans and models of Olympic stadiums’ past and present, including one of the games’ most attractive stadiums, the Bird’s Nest from Beijing 2008 Olympics.The Olympic MedalsHave you ever wondered what an Olympic medal looks like? The Olympic Museum has a room that houses every bronze, silver, and gold medal from every Olympic Games dating back to the first modern Olympics of 1896. Each medal design is a unique representation of the year and location in which the games were held.1.Which moment do you see first when exploring the Olympic Museum?A.The Olympic Park.B.The first Olympic Symbol.C.The Stadiums.D.The Olympic Medals.2.What can you do in the section of The Stadiums?A.Celebrate the glory of a sportsman.B.Meet the designers of the stadiums.C.Explore the future stadiums.D.Enjoy the model of the Bird’s Nest.3.In which column of a newspaper may this text appear?A.Entertainment.B.Science.C.Travel.D.Business.BAfter finishing his dinner, Lin Xu opened a WeChat mini-program called "Clear Plate" on his phone and took picture of the empty plates. He was then awarded 157 credit points after the image was uploaded and recognized by artificial intelligence.“Users of the app can use their credit to buy gifts, such as books and cellphones to purchase charity meals donated to children in poor rural areas,” Lin said.A nationwide "Clear Your Plate" campaign is gaining steam online. Efforts to stop food waste and promote thrift are also being made by restaurants that have been urged to create an environment in which consumers are reminded not to waste food. They are also encouraged to offer different portion sizes so that customers can have more choices.The “Clear Plate” mini-program has become popular among young Chinese and currently has nearly 1 million users.Liu Jichen, founder of the startup that developed the app, said that the idea popped up at a dinner in 2017, when Liu found that a restaurant would give diners who polished off their food a card and offer small gifts after a certain number of cards had been collected.“Such an idea can be realized online,” Liu said. He formed a team to work on the project.Yet it was quite challenge for the AI system to identify whether the uploaded photos showed empty plates.To make the AI system smarter, Liu and his team, assisted by more than 1,000 others, spent half a year collecting over 100, 000 samples in canteens and restaurants across the country and used the data to train neural network. Dozens of enterprises, institutions and restaurants have contacted the startup to cooperate on the project.Through the visualized mini-program, people can clearly see the good results of saving food, which will effectively reduce waste, he noted. "We hope our efforts can start a new trend among the younger generation, encouraging them to carry out the virtue of cherishing food and developing the habit of thrift, " Liu said4.

To raise fund for poor children.CTrees are “social creature” that communicate with each other in cooperative ways that hold lessons for humans, too, ecologist Suzanne Simard says. Simard grew up in Canadian forests as a child of loggers before becoming an ecologist. She's now a professor of forest ecology at theUniversityofBritish Columbia.Trees are linked to neighboring trees by a network of fungi below the surface of the earth that resembles the nervous networks in the brain, she explains. In one study, Simard watched as a Douglas fir tree that had been injured by insects appeared to send chemical warning signals to a pine nearby. The pine tree then produced defense enzymes to protect against the insect.“This was a breakthrough,” Simard says. The trees were sharing “information that actually is important to the health of the whole forest.”In addition to warning each other of danger, Simard says that trees have been known to share nutrients at critical times to keep each other healthy. She says the trees in a forest are often linked to each other via an older tree she calls a “mother” or “hub” tree.“In connecting with all the trees of different ages, the mother trees can actually ease the growth of these young trees,” she says. “The young trees will link into the network of the old trees and benefit from that huge resource capacity. And the old trees would also pass a little bit of carbon and nutrients and water to the young trees, at crucial times in their lives, that actually help them survive.”The study of trees took on a new resonance for Simard when she suffered from breast cancer. During her treatment, she learned that one of the medicines she relied on was actually obtained from what some treesproduce for their own mutual defense. She explains her research on cooperation in the forest, and shares her personal story in the new bookFinding the Mother Tree: Discovering the Wisdom of theForest.8. How could a Douglas fir tree send chemical warning signals to a pine nearby?A. By an underground network of fungi.B. By the nervous networks in the brain.C. By making cooperation with each other.D. By holding lessons to it as human beings.9. According to Simard, what was a breakthrough?A. Simard was-brought up in Canadian forests.B. She became a professor of forest ecology.C. The pine tree produced defense enzymes.D. Vital information was shared among trees.10. What helped Simard understand trees further?A. Her rich knowledge of trees.B. Her childhood in the forest.C. Her medicine gained from trees.D. Her research on cooperation.11. In Simard's book we may discover the wisdom of the forest except .A. communicating cooperativelyB. warning each other of dangerC. sharing nutrientsat critical timesD. sacrificing mother trees for survivalDRain is vital to life on Earth. However, rain isn’t just made of water anymore—it’s partly made of plastic.Millions of tiny pieces of plastic, called microplastics, are wandering around Earth’s atmosphere and traveling across entire continents according to a study published in one journal on April 12.Microplastics are plastic particles less than 5 millimeters in diameter and come from a number of sources. Plastic bags and bottles released into the environment break down into smaller and smaller bits. Some microplastics are produced deliberately to provide abrasion(研磨)in products, such as toothpaste and cleansers. Another major source is your washing machine. When you wash clothing, tiny microfibers get washed away with the wastewater. Even though the water is treated by a wastewater plant, the microplastics remain,and they are released into the sea.Plastic rain may remind people of acid rain, but the former is far more widespread and harder to deal with. The tiny particles, too small to be seen with the naked eye, are collected by the wind from the ground. They are solight that they stay in the air to be blown around the globe. As they climb into the atmosphere, they are thought to act as nuclei (核心) around which water vapor (水蒸气) combines to form clouds. Some of the dust falls back to land in dry conditions, while the rest comes down as rain.Microplastics have been found everywhere you can imagine. From fish and frogs to mice and mosquitoes, their bodies have been found on average to contain 40 pieces of microplastic. As the top of the food chain, humans are exposed to microplastics, too. “We live on a ball inside a bubble,” microplastic researcher Steve Allen said. “There are no borders, there are no edges. It rains on the land and then gets blown back up into the air again to move somewhere else. There’s no stopping it once it’s out.”12. What do we know about microplastics?A. They have a diameter of over 5 millimeters.B. They have become a threat to humans.C. They are light and can be easily dealt with.D. They cause acid rain and plastic rain.13. What does Paragraph 3 mainly talk about?A. Waysto deal with microplastics.B. The wide use of microplastics.C. Where microplastics come from.D. How microplastics pollute water.14. What does Steve Allen want to tell us in the last paragraph?A. No place can be safe from microplastic pollution.B. The atmosphere possesses the ability to self-cleanse.C. Countries should work together to fight pollution.D. Wind causes microplastics to move somewhere else.15. The main purpose of the article is to________.A. call on people to use fewer plastic productsB. warn people of the danger of microplasticsC. introduce the sources and effects of microplasticsD. make a comparison between acid rain and plastic rain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。

These act as antigens totriggerthe development of a protective immune response in the developing young. But that observation raises the question of how the queen receives her antigen supply in the first place? Dr. Harwood wondered if the nurse bees were taking in parts of pathogens and passing them to royal jelly they were producing while eating the food brought to the hive.To test this idea, he teamed up with a group at theUniversityofHelsinki, inFinland, led by Dr Heli Salmela. Together, they collected about 150 nurse bees and divided them among six queenless mini hives equipped with baby bees to look after. Instead of honey, they fed the nurses on sugar water, and for three of the hives they added P. larvae, a bacterium causing a hive-killing disease, to the sugar water.In this case, to stop such an infection happening, Dr Harwood and Dr Salmela heat-treated the pathogens and so killed them in advance. They also labelled the dead bacteria with a fluorescent dye, to track them easily. And, sure enough, it was confirmed that parts of P. larvae were getting into royal jelly released by those bees which had been fed with the sugar water containing that.All told, these findings suggest that nurse bees are indeed, through their royal jelly, passing antigens onto the queen for vaccinating her eggs. They also mean the nurses are vaccinating baby bees as well, because baby bees, too, receive royal jelly for the first few days after they come out.4. What does the underlined word “trigger" in Paragraph 2 probably mean?A. Cut out.B. Set off.C. Slow down.D. Put off.5. Which is the main experimental subject in Paragraph 3?A. Queen bees.B. Nurse bees.C. Bee eggs.D. Baby bees.6. Why was P. larvae added to the sugar water?A. To test if it would cause a hive-killing disease.B. To check how the bacterium would affect the hive.C. To see whether the target bees would favor the taste.D. To confirm the bees would pass pathogens to royal jelly.7. What is the text mainly about?A. How bees multiply.B. How antigens function.C. How bees get vaccinated.D. How immune system works.COlder adults with a better sense of smell may live longer than thosewho have a poor sense of smell, a new study suggests. The study was a project of researchers in theUnited Statesthat was ongoing for over 13 years. They asked nearly 2,300 men and women to identify 12 common smells. All the subjects were from 71 to 82 years of age. The researchers gave the adults scores, from 0 to as high as 12, based on how many smells they identified correctly.During the years of follow-up investigation, over 1,200 of the subjects died. When the study was launched, none of the adults were weak. They could walk a little under half a kilometer, climb 10 steps and independently complete daily activities. In the latest findings, the researchers noted that those with a weak nose were 30 percent more likely to die than people with a good sense of smell. The findings were reported last month in the scientific publication Annals of Internal Medicine.Honglei Chen, a doctor withMichiganStateUniversityinEast Lansing,Michigan, was the lead writer of a report on the study. He said the connection between a poor sense of smell and an increased risk of dying was limited to adults who first reported good-to-excellent health. This suggests that a poor sense of smell is an early and sensitive sign for worsening health before it is recognizable in medical tests. With a poor sense of smell, people are more likely to die of brain and heart diseases, but not of cancer or breathing disorders.The results also suggest that a poor sense of smell may be an early warning for poor health in older age that goesbeyond dementia or other neurodegenerative(神经变性的) diseases. These often signal the beginning of a weakening of the mind or body.8. What do you know about the study mentioned?A. The study involved researchers from the world.B. All the participants were of different ages.C. The study began to be performed about 13 years ago.D. 2 ,300 men and women were young and healthy.9. What was the situation like at the beginning of the study?A. More than 1,200 of the participants passed away.B. Many of the subjects were found with health problems.C. All the subjects were independent of others when walking.D. One third of the participants had a poor smell sense.10. What can be inferred from the last two paragraphs?A. People with a poor sense of smell have heart disease.B. You should be careful with your health if you smell poorly.C. People with a poor sense of smell won't suffer from cancer.D. Most of the elder people may have the dementia disease.11. Which is the best title for the passage?A. Strong Sense of Smell May Be Linked to Longer LifeB. Old People Tend to Have a Poor Sense of SmellC. A Number of Factors Result in Longer LifeD. Being Ill Means Losing the Sense of SmellDMikah Frye, a 9-year-old boy, was walking down the streets with his grandmother discussing Christmas gifts when he saw some homeless people struggling to stay warm in the cold night. Then he was thinking about a way to help the homeless to spend a warm Christmas.That thought stayed in Mikah Frye’s mind and when he reached home, Mikah informed his parents not to buy the Microsoft XBox gaming device he had asked for earlier. Mikah realized that by not buying the $300 device, he could instead donate over 30 blankets to the homeless. He knew how much it meant to be warm in the cold holiday season.Three years ago, Mikah and his parents were the ones living in a homeless shelter. Having suffered a financial crisis, they too had lost their house, not knowing where their next meal would come from and sharing a blanket every night. Mikah was six years old then but he remembered what it was like to have to give back that precious blanket every morning.Reaching out to the emergency shelter programme that looked after them 3 years ago, the family donated 60 blankets in the end, each with a personalized message of hope in Mikah’s handwriting stating: “They gave me a blanket, but I had to leave it. That’s why I want you to have your own blanket. Today, I live in my own house, and someday you will too. Your friend, Mikah.”The homeless people at the shelter may not have been able to give Mikah a Christmas gift in return but his gesture was noted by the billion dollar company Microsoft who made sure that Mikah was fooled into visitingtheir store so that Santa Claus could personally deliver an XBox from the company to him as a reward for making the top of “Santa’s list of nice boys” that year.12. Why did Mikah give up his Christmas gift?A. The device was out of date.B. His parents had a tight budget.C. He wanted to spend a warm Christmas.D. He decided to do something charitable.13. What made Mikah have a better understanding of the situation of the homeless?A. His own experience.B. His parents’ education.C. His visiting to the emergency shelter.D. The cold weather during the holiday season.14. What can be inferred from the last two paragraphs?A. The homeless gave Mikah a gift in return.B. He finally got the gift he wanted on Christmas.C. The company Microsoft fooled Mikah into buying an Xbox.D Mikah wrote a thank-you note to the emergency shelter he lived in.15. What might be the best title for the text?A. Mikah’s Precious Christmas GiftB. Mikah’s Giving Warmth on ChristmasC. Microsoft Rewarded Nice Boys on Santa’s ListD. The Homeless Needed Blankets on a Cold Christmas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。

They don’t listen because they already know it all, I was lucky: I became a pilot in 1970, almost ten years before I graduated from medical school. I didn’t realize then, but becoming a pilot makes me a better surgeon. I loved flying. As 1 flew bigger, faster planes, and in worse weather, I learned about crew resource management (机组资源管理), or CRM, a new idea to make flying safer. It means that crew members should listen and speak up for a good result, regardless of positions.I first read about CRM in 1980. Not long after that, an attending doctor and I were flying in bad weather. The controller had us turn too late to get our landing ready. The attending doctor was flying; I was safety pilot. He was so busy because of the bad turn, he had forgotten to put the landing gear (起落架) down. He was a better pilot—and my boss—so it felt unusual to speak up. But I had to: Our lives were in danger. I put aside my uneasiness sand said, we need to put the landing gear down now! That was my first real lesson in the power of CRM, and I’ve used it in the operating room ever since.CRM requires that the pilot/surgeon encourage others to speak up. It further requires that when opinions are from the opposite, the doctor doesn’t overreact, which might prevent fellow doctors from voicing opinions again.So when I’m in the operating room, I ask for ideas and help from others. Sometimes they’re not willing to speak up. But I hope that if I continue to encourage them, someday someone will keep me from landing gear up.4. What does the author say about doctors in general?A. They like flying by themselves.B. They are quick learners of CRM.C. They pretend to be good pilots.D. They are unwilling to take advice.5. The author deepened his understanding of the power of CRM when .A. his boss landed the plane too lateB. he was in charge of a flying taskC. he saved the plane by speaking upD. his boss operated on a patient6. In the last paragraph landing gear up probably means .A. following flying requirementsB. making a mistake that may cost livesC. listening to what fellow doctors sayD. overreacting to different opinions7. Which of the following can be the best title for the text?A. CRM: A New Way to Make Flying SafeB. A Pilot-Turned DoctorC. The Making of a Good PilotD. Flying Makes Me a Better DoctorCLast summer, Maria and her mother moved from their house in the countryside to a flat building in Chicago. Maria really liked some things about the city, but she missed her house and yard in the countryside.One day, Maria was in her flat building when she noticed her neighbor, Mrs. Garcia, carrying a gardening tool and a bag of soil. Maria wondered how Mrs. Garcia was able to garden in the city.“My mom used to grow the most delicious vegetables, and I know she misses her garden now that we don’t have a yard,” said Maria.Mrs. Garcia laughed. “I’ll show you,” she said.Maria thought that Mrs. Garcia would take her to the park, but she took her to the roof. When the door opened, Maria was surprised to see rows of flowers and vegetables on the roof.“What a wonderful garden!” said Maria.Mrs. Garcia told Maria that for a long time the roof was just an empty space. Then some of the people in the building asked the owners to turn it into a community garden. The building owners liked the idea because the plants not only helped to keep the air clean, but they also helped to keep the building cooler during warmer weather.“I plant flowers in my own place,” Mrs. Garcia said, “but you would be surprised by how different the plants are up here. Some people grow vegetables just like your mom. You can do some of the same things in the city as in the countryside. You just have to be creative!”8. Where did Mrs. Garcia take Maria to one day?A. The park.B. The roof.C. The garden in front of her house.D. The countryside.9. Which of the following is NOT the good side of the community garden?A. It made the building stronger.B. It helped keep the air clean.C. It helped keep the building cooler.D. It used the empty space well.10. After Maria visited the garden, she would most probably ask her mom to ________.A. go back to the countrysideB. pick flowers from the gardenC show her around the park D. grow vegetables on the roof11. What is the best title for this passage?A. A Creative LadyB. An Empty RoofC. A Rooftop GardenD. A Special BuildingDWhen the COVID-19 hit and supermarket shelves were empty, Chris Hall and Stefanny Lowey decided they no longer wanted to rely on others for food. The couple, who live on Pender Island in BritishColumbia, Canada, decided to start a year-long challenge where they wouldn't buy a single thing to eat. Instead they would grow, raise or catch everything—right down to sugar, salt and flour. Now, five months in, they say the challenge has changed their lives.Chris, 38, said, “It has always been something that we have wanted to do. We have had a garden and grown vegetables for a long time already. When the COVID-19 hit, it gave us that extra push that we needed to do it. Wewere both out of work when we started, and with the reality check of grocery stores running out of items, it gave us even more motivation to see if we could look after ourselves.”The pair spent the months before building a house for chickens, ducks and turkey as well as studying as much as possible to figure out where they would get all the things they needed. Chris adds, “We had to learn so many new things like how to grow mushrooms, process our Stevia plants, and harvest salt from the ocean. We spent a lot of time reading and studying online to figure out all the things we were going to need to do.”Now after five months, they both feel its been going well but Chris admits the first few weeks were difficult. “The first three weeks were very challenging as our bodies adjusted to cutting out coffee, wine and sugar all on the same day,” he says. “After three weeks our energy levels balanced out and our wishes reduced and now we feel great.” Now February has ended. As they come through winter, they feel positive about continuing with this way of living, with their challenge officially ending in August.12. Why did the pair decide to produce foods on their own?A. They were isolated by Pender Island.B. They couldn't afford to buy them because they were out of work.C. They believed it's good for their health.D. They could hardly buy them in shops.13. Which words can be used to describe the couple?A. Rich and generous.B. Helpful and positive.C. Optimistic and self-dependent.D. Motivated and brave.14. What can we learn from the last paragraph?A. Their challenge may last about eleven months in total.B. They were discouraged by the difficulty at first.C. They had difficulty because they wanted more.D. They couldn't adjust their bodies to the hard work after three weeks.15. In which column may you read such a passage?A. Sports.B. Agriculture.C. Lifestyle.D. Business.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。

But he was not the only great master of play writing to die in 1616, and he is certainly not the only writer to have left a lasting influence on theater.While less known worldwide, Tang Xianzu is considered one of Chinas greatest playwrights and is highly spoken of in that country of ancient literary and dramatic traditions.Tang was born in 1550 inLinchuan,Jiangxiprovince. Unlike Shakespeare's large body of plays,poems and sonnets (十四行诗), Tang wrote only four major plays: The Purple Hairpin, Peony Pavilion (《牡丹亭》), A Dream under the Southern bough, and Dream of Handan. The latter three were constructed around a dream narrative, a way through which Tang unlocked the emotional dimension of human desires and ambitions and explored human nature beyond the social and political limits of that time.Similar to Shakespeare, Tang's success rode the wave of a renaissance (复兴) in theater as an artistic practice. As in Shakespeare'sEngland, Tang's works became hugely popular inChinatoo. During Tang'sChina, his plays were enjoyed performed, and changed. Kunqu Opera, a form of musical drama, spread from southernChinato the whole nation and became a symbol of Chinese culture. Combining northern tune and southern music, kunqu Opera was known for its poetic language, music, dance movements and gestures. Tang's works benefited greatly from the popularity of kunqu Opera, and his plays are considered classics of kunqu Opera.While Tang and Shakespeare lived in a world away from each other, there are many things they share in common, such e humanity of their drama, their heroic figures, their love for poetic language, a lasting popularity and the anniversary during which we still celebrate them.1. Why is Shakespeare mentioned in the first paragraph?A. To describe Shakespeare's anniversary.B. To introduce the existence of Tang Xianzu.C. To explain the importance of Shakespeare.D. To suggest the less popularity of Tang Xianzu.2. What's possibly one of the main theme of Tang's works?A. Social reality.B. Female dreams.C. Human emotions.D. Political environment.3. What does the author mainly tell us in Paragraph 4?A. The influence of Kunqu Opera on Tang's works.B. Tang's success in copying Shakespeare's styles.C. The way Kunqu Opera became a symbol of Chinese culture.D. Tang's popularity for his poetic language and music.BElizabeth Bishop is considered one of the best American poets of the 20th century. She was born in Worcester, Massachusetts in 1911. Her dad died when she was just a baby and her mom never recovered from the loss. She went to live with her grandparents in Nova Scotia, Canada when she was five. Eventually Bishop attended Vassar College, where she began to write poetry.At Vassar she discovered Marianne Moore's poetry and met Ms Moore and began their life-long friendship. She later met poet Robert Lowell. She wrote tons and tons of letters to both of them, which is good for us because we would otherwise know very little of her personal life.Bishop published her first book of poetry in 1946 and wrote until her death in 1979. She would spend years working on a single poem. Her poems are not the result of hasty scribbling (匆忙乱写) on paper while eating breakfast. She would look through drafts of poems again and again and improve them until they were as close to perfect as she could get them.Reading Elizabeth Bishop is like being transported to the very place, the very moment she's writing about. She leads us to a microscope so we can see every smallest part of the scene. It seems that she's always asking us to notice more, and more until the poem is so clear in our minds that it's almost painful—like a light that's too bright.4. What do we know about Bishop's early life?A. She was mainly brought up by her grandparents.B. She spent her childhood mainly in Worcester.C. She was always encouraged by her parents.D. She started to write poems at five.5. Why are Bishop's letters to Moore and Lowell important?A. They have a deep influence on other poets.B. They offer much information about her life.C. They help us study Moore and Lowell's poetry.D. They prove she had friendships with famouspoets.6. What can we say about Bishop's poetic creation?A. She liked to write in the morning.B. She could write poems at high speed.C. She tried her best to achieve perfection.D. She published hundreds of books of poetry.7. Which word can be used to best describe the style of Bishop’s poems?A. Enthusiastic.B. Romantic.C. Humorous.D. Exact.CAfter almost an entire year of not going shopping and vacationing, you find the numbers reflected by your bank account meet your heart’ s desire.Now the most important question comes, what to do with the earnings? Should you fulfill dreams of the present, invest in preserving the future or perhaps keep saving it for a rainy day?Our elders always try to teach us the value of money and its moral weakness. One may be on a winning streak (连续成功) now, but it will not always be so. One will have days when there will be no sunshine but only rain, and their luck will hide behind those thick grey clouds. Save for those rainy days, they say. Do not spend too much, live within a budget,refrain fromcredit no matter how small and save for the future.Since the very first time we earn our own money from a summer job or earning our first salary, the lessons start. In fact, the pocket money that we receive when we are children begins the process of learning how to best manage one’ s money.People often think like this — one day when I have enough money, I will travel the world. Then, once we do earn enough money, tomorrow’ s plans start shadowing our present ones. However, is it wise to keep living for that future? Will we still enjoy or even be able to backpack in our 50s? How will we ever enjoy our present if we are constantly living for the future?Good questions, aren’ t they? I say travel but don’ t let yourself run dry, treat yourself to some luxuries but also keep enough for your necessities, and enjoy your present but with a plan for the foreseeable future. Life is for the living, so live it sensibly.8. Why do elders teach us to save money?A. Because there are more rainy days in life.B. Because no one can win streak.C. Because good days may end.D. Because money can’t buy everything.9. What does the underlined phrase “refrain from” mean in Paragraph 3?A. select fromB. hold backC. rely onD. prefer to10. Which of the following opinions would the author agree?A. To enjoy yourself in the right time.B. To wait to travel until we have enough money.C. To go backpacking in our 50s.D. To live for the future.11. What should we do with the earnings according to the author?A. We should save all for rainy days.B. We should fulfill our dreams.C. We should entertain ourselves.D. We should live the present wisely.DScientists have discovered a new behaviour among bumblebees that tricks plants into flowering early.When lack of pollen, bumblebees will bite little by little on the leaves of flower-less plants. The damage seems to fool the plant into flowering, sometimes up to 30 days earlier than normal.With their hairy appearance and special sounds, bumblebees are hard to miss in gardens all over the world. Their hairy bodies make them excellent pollinators for crops like tomatoes and blueberries. They are among the first bees to appear each year and work a long season.But despite their key role, bumblebees, like many other pollinators have seen their numbers decline suddenly in recent decades. One recent study pointed to climate change, reporting that an increasing number of hot days in Europe andNorth Americawas raising local bumblebees extinction rates.But researchers have now made a discovery about bumblebees that could have something to do with their long term survival. Scientists inSwitzerlandfound that when the bumblebees were out of pollen, they started to bite on the leaves of plants that hadn't yet flowered. They used their mouths to cut clearly-shaped holes in the leaves. But the creatures didn't eat the material or use it in their nests.The damaged plants responded by flowering earlier than normal--in some cases up to 30 days ahead of schedule. Researchers also found that the bee damaged plants flowered 30 days earlier than undamaged plants and 25 days earlier than ones damaged by the scientists.“I think everything that we've found is consistent with the idea that the bumblebees are damaging the plants and that that's an adaptation that brings flowers earlier and that benefits the bees,” said Dr Mark Mescher, one of the authors from ETHZurich.12. How do bumblebees fool plants into flowering earlier?A. By making use of the hot weather.B. By putting the false flowers on the leaves.C. By attacking the leaves of flowerless plants.D. By taking away the pollen from the other flowers.13. What's bumblebees’ key role?A.Making plants flower early.B. Spreading pollen to flowers and plants.C. Sending information about weather change.D. Finding out whether the plant has flowers.14. What has happened to bumblebees in the past the years?A. They are becoming homesick.B. They are not as friendly as before.C. There is a sharp decrease in number.D. They have been busy year by year.15. What's Dr Mark Mescher's attitude towards the behaviour of bumblebees?A. Uncaring.B. Skeptical.C. Tolerant.D.

2021年广州市第一一七中学高三英语下学期期末试题及答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AJuanito Estrella has been a housekeeping manager on the US-based large passenger ship Carnival Spirit for 18 months and feels he has found the suitable position in his career(职业). He has always wanted to travel. “I guess I am a really restless spirit.I like traveling, so when the chance came, I jumped at it,” he says.The chance came in the form of a newspaper advertisement for work on cruise ships（游船）. At the time Estrella was the housekeeping manager at a Melbourne hotel. He applied and, after two interviews, a medical check and police clearance, the job was his.Estrella is responsible(负责的)for the cleanliness of the ship, making sure that 160 crew work properly. “I enjoy it because there is no other work-you wake up each day in a different place anda different culture. It’s exciting when you go to the next country and you don’t understand the language,” he says.Estrella likes being busy and getting to know people from all over the world. The 1,000 crew come from 94 countries, and Estrella has learnt Spanish and a little Croatian.But there is adownside. “You cannot get really drunk...because you have safety responsibilities to yourself and others,” he says. “You don’t really think about home.You start to think about home only when you get closer to your vacation and wonder what you’ll be doing.”Life on the ship is anything but cruising. Estrella and his fellows work at least 10 hours a day, seven days a week. He warns the job is not for everybody. “You have to love being busy and be prepared to work every day-and to give up drinking too much alcohol.” In his spare time, if the ship sails into a port, Estrella explores it, otherwise he works out in the crew’s gym, goes on the internet or calls home.1.Which of the following is true?A.He has been a housekeeping manager for 18 months.B.He doesn’t drink wine now.C.He cannot speak a foreign language.D.He used to be a housekeeping manager.2.The underlined word“downside”in paragraph 5 probably means ________ .A.disappointmentB.disadvantageC.failureD.loss3.In the last paragraph, the writer thinks that life on the ship is ________.A.not a tiring journey at allB.just an interesting voyageC.far from a voyage for pleasureD.more than a pleasant travel by seaBIdentifying the chemical makeup of pigment (色素) used in ancient documents, paintings, and watercolor1 s is criticalto restoring and conserving the precious artworks. However, despite numerous efforts, scientists had been unable to determine the source of folium, a popular blue dye used to color1 manuscripts (手稿) in Europe during the middle ages — from the 5th to the 15th century. Now, a team of researchers fromPortugalhas finally uncovered the mysterious ingredient responsible for the gorgeous blueish-purple color1 that helped bring ancient illustrations and texts to life.The research team began byporing overinstructions penned by European dye makers from the 12th, 14th, and 15th centuries. They found what they were seeking in a 15th-century text entitledThe Book on How to Make All the Color Paints for Illuminating Books. However, translating the instructions was no easy task. It was written in the now extinct Judaeo-Portuguese language, and though the source of the dye was traced back to a plant, no name was mentioned.However, by piecing together suggestions from the text, the scientists were able to determine that the dye was made from the bluish-green berries of the chrozophora tinctoria plant. After an extensive search, the team found a few varieties of the plant growing along the roadside near the town ofMonsarazin southPortugal.The detailed instructions gave the researchers critical clues — including the best time to pick the berries. “You need to squeeze the fruits, being careful not to break the seeds, and then to put them on linen (亚麻).” The scientist says the detail was important since broken seeds polluted the pigment, producing an inferior quality ink. The dyed linen, which was left to dry, was an efficient way to store and transport the pigment during ancient times. When needed, the artist would simply cut off a piece of the cloth and dip it with water to squeeze out the blue color1 .Once the key ingredient had been identified, the researchers began to determine the dye’s molecular structure. To their surprise, they found that folium was not like any other known permanent blue dyes — it was an entirely new class of color1 , one they named chrozophoridin. “Chrozophoridin was used in ancient times to make a beautiful blue dye for painting.” the team wrote in the study. “Thus, we believe that this will not be our final word on this amazing plant and its story and that further discoveries will follow soon.”4. The primary purpose of the study is to ________.A. restore and conserve ancient precious artworksB. determine the substance making up the foliumC. prove the ancient dye-making technique was organicD. identify which class of color1 folium belongs to5. The underlined phrase “poring over”in the second paragraph means ________.A. discussing publiclyB. testing repeatedlyC. passing directlyD. reading carefully6. What can be learned about the blue dye folium?A. It was essentially an inferior type of ink.B. It was the only kind made from wild berries.C. It could be carried and used easily.D. It was carefully squeezed from broken seeds.7. The article is mainly about _________.A. how the mystery ofa thousand-year-old blue dye was solvedB. why the researchers took the trouble to recreate the dyeC. what needs to be done to make an organic dye from a plantD. when and where the discovery of the dye was madeCThis is Scientific America's 60-Second Science. I am Christopher Intagliata.The Apollo missions brought back 842 pounds of rock and soil from the moon, that's nearly 2200 different samples. But the most interesting one, according to a scientist Meenakshi Wadhwa, is a sample named "Apollo 1-0-0-8-5collected by Neil Armstrong on Apollo 11.“He was about to step back into the lunar module(登月舱) when he turned around and saw there were little spaces in the rock box. He knew that geologists on earth would be just so excited to study these materials, so he just scooped up nine scoops(勺) of soil and put it into the box." Wadhwa explained.It was one of the most well studied samples of the Apollo missions. And a geologist named John Wood noticed white flecks(微粒) of rock in the soil, which inspired him to dig deeper into the moon's ancient past.“This was quite a leap of imagination — he proposed that the whole of the moon had been almost covered with a magma(岩浆) ocean nearly 4.5 billion years ago. This was a revolutionary idea at the time, because peoplehad thought the moon had formed cold, so it completely changed our idea how the moon formed.”But Wadhwa has a more personal reason to appreciate this sample. She met her husband Scott Parazynski also because of this rock sample. Scott, a mountaineer at that time, wanted to climbMount Everestwith a moon rock while Wadhwa was the chairman of the NASA committee that gives access to the samples for scientific purposes.Neil Armstrong's last-minute scoop of moon dust brought two people together here on Earth and upturned our understanding of how the moon — and the Earth itself-got here.Thank you for listening for Scientific American's 60-Second Science.8. It can be learned from Paragraph 3 that ________ .A. Neil Armstrong was excited to find the soilB. the spaceship was about to land on the moonC. Sample "Apollo1-008-5" was collected at the last minuteD. scientists were not satisfied with the samples brought back by Neil9. Which of the following statements is TRUE according to the text?A. Scott made a new proposal about the moon's origin.B. The Apollo missions brought back 842 rock samples.C. "Apollo 1-0-0-8-5" brought new evidence to the moon's formation.D. Wadhwa and her husband climbedMount Everestwith a moon rock.10. What is this text?A. A short interview.B. An introduction to a scientist.C. An inspiring speech.D. A broadcast story of a program.11. What is the text mainly about?A. A romantic story of a moon rock.B. A big leap made by Neil Armstrong.C. An unusual task for Apollo missions.D. An unexpected discovery in moon exploration.DWe are in lack of enough sleep, according to Arianna Huffington, the co-founder and editor-in-chief of The Huffington Post. And thishas great consequences on our health, our job performance, our relationships and our happiness. What is needed, she ly declares, is nothing short of a sleep revolution. Only by renewing ourrelationship with sleep can we take back control of our lives.In her bestseller Thrive, Arianna wrote about our need to redefine success through wellbeing, wisdom, wonder, and giving. Her discussion of the importance of sleep as a gateway to this more fulfilling way of living struck such a powerful chord (弦) that she realized the mystery and transformative power of sleep called for a fuller investigation (调查).The result is a scientifically sweeping and personal exploration of sleep from all angles, from the history of sleep, to the role of dreams in our lives, to the consequences of sleep deprivation (剥夺), and the new golden age of sleep science that is showing the vital role sleep plays in our every waking moment and every aspect of our health — from weight gain, diabetes, and heart disease to cancer and Alzheimer’s.In The Sleep Revolution, Arianna shows how our cultural removal of sleep as time wasted damages our health and our decision-making and our work lives and shortens our personal lives. She explores all the latest science on what exactly is going on while we sleep and dream. She decides the dangerous sleeping pill industry, and all the ways of our addiction to technology disturb our sleep. She also offers a range of recommendations and tips from leading scientists on how we can get better and more restorative sleep.In today’s fast-paced, always-connected and sleep-deprived world, our need for a good night’s sleep is more important than ever. The Sleep Revolution both sounds the alarm on our worldwide sleep crisis and provides a detailed road map to the great sleep awakening that can help transform our lives, our communities, and our world.12. What is the first paragraph mainly about?A. The importance of sleep.B. The necessity of improving sleep.C. The way to improve our sleep.D. The effect of sleep on health.13.

He had saved upmoney to pay for his tuition, but when he received the college's President's Scholarship, he decided to take his savings and donate it to other students in need.“It comes from my family education and faith," Nelson said. "I've always lived by strong principles as far as being a cheerful giver andhaving an open handwhen it comes to giving back so I feel like that really motivated me.”SEMO's President's Scholarship is the school’s most celebrated, and is only awarded to five top students annually. Nelsonsaid he sat down and outlined how a scholarship could work to help future students who need financial assistance for college. Originally the plan was to give away $ 1,000 the one time, but then he met up with his counselor (顾问), Yolanda Curry, to work outa game plan.“I wasn't expecting it at all!” Curry said. "He told me he had a great idea and wanted to share it with me. I could tell he was really excited.Nelson, in association with his high school, set up the Joshua Nelson Leaders In Action Scholarship fund. Each year, $1,000 will be awarded to a senior.

It never supports high school students.B. It was set up more than ten years ago.C. It was founded by Nelson and Curry.D. It is going very smoothly.C“My P.E. teacher taught me maths.”It has been a common joke for years but when a P.E. teacher applied for the head-teacher job, many parents worried that “the joke could come true”. Some parents asked, “Does the P.E. teacher know maths and English?If not, how is he supposed to tutor the students?” But there were still parents who believed P.E. teachers had more time to discipline the students since they didn’t have many classes.This concern is actually a “subject bias”, that is, choosing a P.E. teacher as the head-teacher is not good for the students’ grades since he doesn’t know Chinese, maths, or English. It is acceptable for Chinese teachers, maths teachers and English teachers to be head-teachers because these subjects are important to entrance exams and scores. Such a concern reflects parents’ anxiety in the current educational environment, which tends to link the head-teacher’s responsible subject with the facts whether the school cares about the class and the children’s performances in the subject.Many people care about their kids’ academic performances only. They don’t care about their kids’ P.E. performance at all. Even if kids have P.E. classes, parents care little. P.E. teachers are in humble position and their classes are often occupied by other teachers. Of course, if students, P.E. performance is related to grades and entrance exams, parents won’t mind “a P.E. teacher being the head-teacher”.At the moment, P.E. is gradually included in entrance exams.In terms of high school entrance examination,Guangzhouwill launch a new high school entrance exam which includes P.E. performance and Health examination in 2021, raising the score to 70 points.In terms of the college entrance examination, universities having the right of independent enrollments added P.E. tests to their entrance exams in 2019. This practice is seen as an important signal that the assessment of physical fitness and athletic ability, which are important aspects of a student’s overall quality, may be included in the college entrance examination in the future.We hope that it’s a trend for P.E. teachers, music teachers and art teachers to become head-teachers.8. By saying “My P.E. teacher taught me maths”, what does the author intend to show us?A. It is just a joke that seldom happened in reality.B. P.E. teachers hardly assist students in maths.C. P.E. teachers are good at teaching maths..D. Parents doubt the ability of P.E. teacher.9. We can infer from paragraph 2 that a P.E. teacher .A. is of little benefit for students’ academic performanceB. is humbler than Chinese, math or English teachersC. reflects whether the school cares about the classD. gets unfairly judged due to the current educational system10. Why doesGuangzhouraise proportion of P.E. performance in high school entrance examination?A. To raise students’ awareness of physical health.B. To call on parents to pay attention to P.E. teachers.C. To test the overall ability of high school students.D. To make P.E. teachers equal with other teachers.11. What opinion does the author hold towards P.E. teachers working as head-teachers?A. Neutral.B. Unexpected.C. Supportive.D. Critical.DHappiness is not a warm phone, according to a new study exploring the link between young life satisfaction and screen time. 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 and exercising — 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.12. 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.13. 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.14. 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.15. 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 Unhappier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。

Medicine .BThe AI research arm of Alibaba created a machine learning model that received a higher score on the Stanford Question Answering Dataset than humans. The database consists of more than 100,000 questions to test reading comprehension.In early January this year the Alibaba AI software machine scored 82.44 on the test while humans scored 82.304. Besides, computers and AI have already defeated humans, for example in games such as chess. However, it seemed that language skills were superior in humans as machines find languages hard to master.A large number of call center employees, often in developing countries, may be out of work soon if the AI robots are cheaper and as effective as human labor. Soon when you phone a company for information the conversation will go like this: “ We are sorry but all our robots are busy right now. We value your call. Please stay on the line until a robot is free to serve you. There are just 12 callers ahead of you.” A robot will serve you some popular tunes while you wait.Si Luo, who is a chief scientist of natural language processing at Alibaba’s AI research group noted that questions such as “What causes rain?” can now be answered with a high degree of accuracy by robots. Si Luo said, “ We believe the foundational technology can be gradually applied to a lot of applications such as customer service, museum tutorials, and online responses to inquiries from patients, freeing human efforts in a new way.”Si Luo’s team is working closely with Ali Xiaomi, a mobile customer service chatbot. Ali Xiaomi can be customized to be used on Alibaba’s platforms such as Taobao and Tmall. The new AI robots could answer consumers’ questions as they did the Stanford questions. The robots would look for the answers from prepared information. However, there are limits to what the system will be able to do. If questions do not have clear-cut answers, or the questions asked are too unclear or ungrammatical, the robot may not be able to deal with them. 4. What can we learn about the Alibaba AI software machine?A. It has been tested in some areas.B. It has become popular since January.C. It has offered a special learning style.D. It has made people interested in reading.5. What does the example in paragraph 3 show about the AI robots?A. They should have better language skills.B. They may replace humans in some fields.C. They need to be customized to serve customers.D. They will be widely used in developing countries.6. How does Si Luo feel about the foundational technology?A. Doubtful.B. Worried.C. Curious.D. Confident.7. What can we infer from the lastparagraph about Ali Xiaomi?A. It needs to improve in some ways.B. It is connected with another system.C. It is a platform to show good service.D. It can answer any questions accordingly.COlder adults with a better sense of smell may live longer than thosewho have a poor sense of smell, a new study suggests. The study was a project of researchers in theUnited Statesthat was ongoing for over 13 years. They asked nearly 2,300 men and women to identify 12 common smells. All the subjects were from 71 to 82 years of age. The researchers gave the adults scores, from 0 to as high as 12, based on how many smells they identified correctly.During the years of follow-up investigation, over 1,200 of the subjects died. When the study was launched, none of the adults were weak. They could walk a little under half a kilometer, climb 10 steps and independently complete daily activities. In the latest findings, the researchers noted that those with a weak nose were 30 percent more likely to die than people with a good sense of smell. The findings were reported last month in the scientific publication Annals of Internal Medicine.Honglei Chen, a doctor withMichiganStateUniversityinEast Lansing,Michigan, was the lead writer of a report on the study. He said the connection between a poor sense of smell and an increased risk of dying was limited to adults who first reported good-to-excellent health. This suggests that a poor sense of smell is an early and sensitive sign for worsening health before it is recognizable in medical tests. With a poor sense of smell, people are more likely to die of brain and heart diseases, but not of cancer or breathing disorders.The results also suggest that a poor sense of smell may be an early warning for poor health in older age that goesbeyond dementia or other neurodegenerative(神经变性的) diseases. These often signal the beginning of aweakening of the mind or body.8. What do you know about the study mentioned?A. The study involved researchers from the world.B. All the participants were of different ages.C. The study began to be performed about 13 years ago.D. 2 ,300 men and women were young and healthy.9. What was the situation like at the beginning of the study?A. More than 1,200 of the participants passed away.B. Many of the subjects were found with health problems.C. All the subjects were independent of others when walking.D. One third of the participants had a poor smell sense.10. What can be inferred from the last two paragraphs?A. People with a poor sense of smell have heart disease.B. You should be careful with your health if you smell poorly.C. People with a poor sense of smell won't suffer from cancer.D. Most of the elder people may have the dementia disease.11. Which is the best title for the passage?A. Strong Sense of Smell May Be Linked to Longer LifeB. Old People Tend to Have a Poor Sense of SmellC. A Number of Factors Result in Longer LifeD. Being Ill Means Losing the Sense of SmellDI don’t think I can recall a time whenI wasn’t aware of the beauty of the ocean. Growing up inAustralia, I had the good fortune of having the sea at my side. The first time I went toHalfmoonBay,I suddenly had the feeling of not being able to feel the ground with my feet anymore.For my 10th birthday, my sister and I were taken out to theGreat Barrier Reef. There were fish in different color1 s, caves and layers of coral. They made such an impression on me. When I learned that only one percent ofAustralia’sCoral Seawas protected, I was shocked. Australian marine (海洋的) life is particularly important because the reefs have more marine species than any other country on earth. But sadly, only 45% of the world’s reefs are considered healthy.This statistic is depressing, so it’s important for usto do everything to protect them. The hope that theCoral Searemains a complete ecosystem has led me to take action. I’ve become involved with the Protect Our Coral Sea activity, which aims to create the largest marine park in the world. It would serve as a place where the ocean’s species will all have a safe place forever.Together, Angus and I created a little video and we hope it will inspire people to be part of the movement. Angus also shares many beautiful childhood memories of the ocean as a young boy, who grew up sailing, admiring the beauty of the ocean, and trying to find the secrets of ocean species.12. What can we learn about the author from the underlined sentence inPara. 1?A. He seldom went surfing at the sea.B. He forgot his experiences about the ocean.C. He never went back to his hometown.D. He had a wonderful impression ofHalfmoonBay.13. What is Australian marine life like according to the second paragraph?A. It is escaping from theCoral Seagradually.B. It depends on reefs for living greatly.C. It may be faced with danger.D. It is protected better than that in other oceans.14. What’s the purpose of The Protect Our Coral Sea activity?A. It is intended to contribute to a complete ecosystem.B. It is intended to prevent more marine species being endangered.C. It is intended to set up a large nature reserve for reefs.D. It is intended to raise more teenagers’ environmental awareness.15. Why do Angus and the author create a little video?A. To urge more people to take action toprotect the marine species.B. To inspire more people to explore the secret of the ocean.C. To share their childhood experiences about the ocean.D. To bring back to people their memory of ocean species.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。

Green CircleBA Bridge Linking Art and the AudienceAccording to a 2018 report, people aged between 16 and 24 make up about 15 percent of the population but only 10 percent of museum-goers. Similarly, people aged over35 go half as much as you would expect from their population size. We have reached the point of recognising the disconnection between art and the audience but haven’t yet determined how to bridge the gap. Two answers to tackling this challenge lie in telling a greater diversity of art histories and communicating these stories in more accessible ways.In 2018, a radio program called Art Matters was started with the aim of discussing art from a pop-culture viewpoint with topics that would engage younger and more diverse audience. It offers an accessible pathway to art history with conversations on different topics. Art history is about storytelling; art content shines when there is an effort to bring audience along for the discussion.More traditional institutions are paying attention. Recently theGettyMuseumissued a social-media challenge for people to recreate paintings using items they had at home. Users displayed incredible creativity, and the museum was flooded with submissions. This reaction proves that there is a potential desire for the audience to engage with art topics if the format is appealing. Since many people feelintimidatedand think that there’s a base level of understanding required to join the conversation, the Getty initiative serves as a reminder that there are many pathways to engaging with it.Another result of the Getty challenge was the exposure given to a diversity of artworks. The famous opera singer Peter Brathwaite, for example, made scores of attractive recreations highlighting centuries of blackpaintings. His efforts opposed the idea that there were not many historical paintings of black figures. It is extremely important that we do a better job of showing the complex and diverse stories that are represented in art.Social media have offered a platform for people who have not traditionally had a seat at the table. Anyone can recognise a gap in the field and address it. Accounts have gathered tens of thousands of followers. They are the proof that there is hunger to hear these art histories, and these themes work brilliantly for museum programming.But there is only so much that can be done without the museums and galleries changing meaningfully from within. We need to see a better balance of these stories represented in permanent collections. We also need a much wider diversity of people and interests represented on board. Ensuring that art-and writing and talking about art-is able to continue on the rising generation of storytellers, inside and outside of institutions, getting the funding and support they need to paint a brighter picture for the part.4. What challenge is the author trying to tackle?A. People doubt a great diversity of artworks.B. Fewer and fewer young people go to museums.C. Art appears too distant from common audience.D. Adult audience has a different understanding of art.5. What does the underlined word “intimidated” in Paragraph 3 probably mean?A. Tired.B. Worried.C. Annoyed.D. Surprised.6. In the author’s opinion, the museums and galleries should ________.A. make the art history stories accessible in a traditional way.B. change meaningfully for activities like the Getty challenge.C. limit the number of storytellers both in and out of institutions.D. improve the permanent collections by adding famous artworks.7. We can conclude from the passage that common audience ________.A. lacks the channels to understand and talk about art history.B. prefers to view artworks and hear art stories on social media.C. feels satisfied with people and interests represented on board.D. refuses to engage with diverse art topics and art history stories.CElonMusk is a symbol of passion, hard work and success. A person may work hard in his life, but when hard work goes along with passion and a new idea, then something is created that astonishes the world. As the founder of big companies like PayPal, SpaceX, and Tesla Motors, Elon Musk is a guide and inspiration for the youth around the world.Elon Musk was born on June 28,1971 inPretoria,South Africa. He was the eldest of three children. His father Errol Musk, a British-born South African, was an engineer. Musk spent his childhood inSouth Africaand at the age of 9, he got his first personal computer. This got Elon interested in programming and he started to learn on his own. At the age of 12, he made his first computer game, Blaster, which earned him $500 when he sold the source code to a magazine.When he was 17, he decided to leave home and had wanted to move to theUnited Statesafter graduating from a secondary school inPretoria. However, he was unable to move to theUnited States. In 1989, Elon Musk moved toCanada, where his mother’s s lived. After obtaining Canadian citizenship, Musk went toMontreal. Due to a lack of money, he found a low-paying job. At the age of 19, he enteredQueensUniversityinKingston,Ontario, studying there for two years. Finally, in 1992, his dream came true—he moved to theUnited States.As a teenager, Musk struggled with depression. But then he realized that the most important thing was presenting himself with the right questions. The day he started doing this, everything started to get easier.Musk thought that a human being had to expand the limits of his consciousness—to ask the right questions and get answers to them; thus he asked the best question of all: what will have the greatest impact on the future of humans? Musk found that these things were the Internet and space exploration.The life of Elon Musk is inspiring. He found success on the Internet, without much formal learning. By reading books and using his willpower and dedication, he reached a level of knowledge that is difficult to imagine. He did not give up until he achieved his dreams. Elon Musk truly stands out among other billionaires because of his leadership abilities, positive attitude, ability to know when to take risks, and belief in futuristic technologies.8. According to the passage, Elon Musk gained knowledge of computer by ________.A. teaching himselfB. learning from his fatherC. taking online coursesD. studying inQueensUniversity9. What made things easier for Elon Musk when he suffered from depression?A. Expanding knowledge by reading books.B. Asking himself the right questions.C. Achieving success on the Internet.D. Designing computer games.10. What can we learn from the passage?A. It’s never too late to learn.B. Youth means limitless possibilities.C. Where there’s a will, there’s a way.D. He who doesn’t advance falls backward.11. Which words can best describe Elon Musk according to the passage?A. Optimistic and generous.B. Ambitious and determined.C. Independent and helpful.D. Adventurous and realistic.DHardware in general,and smartphones in particular,have become a huge environmental and health problem in the Global South's landfill sites(垃圾填埋场).Electronic waste(e-waste) currently takes up 5 percent of all global waste,and it is set to increase rapidly as more of us own more than one smartphone,laptop and power bank They end up in places like Agbogbloshie on theoutskirts of Ghana's capital,Accra. It is the biggest e-waste dump in the world,where 10,000 informal workers walk through tons of abandoned goods as part of an informal recycling process.They risk their health searching for the precious metals that are found in abandoned smartphones.But Agbogbloshie should not exist.The Basel Convention,a 1989 treaty,aims to prevent developed nations from unauthorized dumping of e-waste in less developed countries.The e-waste industry,however,circumventsregulations by exporting e-waste labelled as "secondhand goods' to poor countries like Ghana,knowing full well hat it is heading for a landfill site.A recent report found Agbogbloshie contained some of the most dangerous chemicals.This is not surprising: smartphones contain chemicals like mercury（水银）,lead and even arsenic(砷).Reportedly, one egg from a free-range chicken in Agbogbloshie contained a certainchemical which can cause cancer and damage the immune system at a level that's about 220 times greater than a limit set by the European Food Safety Authority(EFSA).Most worryingly,these poisonous chemicals are free to pollute the broader soil and water system.This should concern us all, since some ofGhana's top exports are cocoa and nuts.Some governments have started to take responsibility for their consumers' waste.For example,Germanyhas started a project that includes a sustainable recycling system at Agbogbloshie,along with a health clinic for workers.However,governments cannot solve the problem alone, as there is an almost limitless consumer demand for hardware,especially when governments' green policies are focused on issues like climate change.Only the manufacturers can fix this.A more economically sustainable and politically possible solution is through encouraging hardware manufacturers to make the repair, reuse and recycling of hardware profitable,or atleast cost-neutral12. What can we infer from Paragraph 2?A. Electronic waste requires more landfill sites acrossGhana.B. Electronic waste is too complex to get fully recycleC. Electronic products need to be improved urgentlyD. Electronic pollution is a burning question in Agbogbloshie13. What does the underlined word "circumvents"in Paragraph 3 mean?A. AbolishesB. TightensC. Brings inD. Gets around14. What should be the best concern according to the text?A. The thread of polluted food around the worldB. The damage of chicken’s immune systemC. The lack of diversity inGhana's exportsD. The violation of EFSA's standards15. What does the author think is the best solution to the e-waste problem?A. Manufacturers' developing a sustainable hardware economyB. Governments’ adjusting their green policies about e-waste.C. Reducing customers' demands for electronic productsD. Manufacturers’ urging the government to make effective policies to ensure more profit.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。
