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!”4. 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.5. 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.6. 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 roof7. What is the best title for this passage?A. A Creative LadyB. An Empty RoofC. A Rooftop GardenD. A Special BuildingCBarred owls(大林鸮猫头鹰) are a large species native to eastern North America, but they began moving west at the start of the 20th century. By 1973,large numbers of barred owls had arrived in the western state ofWashington. Later they moved south intoOregonandCalifornia.In parts of thePacific Northwest, the owls are now believed to be causing a drop in the population of a smaller, less aggressive bird: the northern spotted owl. In many ways, the barred owl is the spotted owl's worst enemy. The barred owl has more babies per year and eats the same animals, like squirrels and wood rats. And their numbers are now larger in many parts of the spotted owl's traditional territory.David Wiens is a biologist with the U.S. Geological Survey, a federal agency that studies the Earth and its natural resources. He and other officials are doing something unusual to protect spotted owls: killing barred owls. It is a controversial, experimental program. More than 2,400 barred owls have already been shot.Wiens is the son of a well-known bird expert and grew up with the fascination for birds. He has mixed feelings about the program. "It's a little distasteful, I think, to go out killing barred owls to save another owl species," he says. But he adds, “We knew that barred owls were out competing spotted owls and their numbers were growing too fast."To catch barred owls, officials put digital bird callers on the ground. Then they step back and wait as several sounds from the devices fill the air. All of this happens in the dark of night. Barred owls dislike other birds in their territory, so they will fly down and chase other owls out. That is when Wiens and his team try to shoot them.8. What's the main problem with spotted owls?A. They are being starved to death.B. They have more babies each year.C. They are invaded by another bird.D. They are hunted by man.9. Why are barred owls being killed?A. They are eating the spotted owls.B. They are killing each other to survive.C. They are putting the spotted owls in danger.D. They are destroying large areas of forests.10. Why did the officials release the bird sounds?A. To kill barred owls.B. To puzzle barred owls.C. To protect barred owls.D. To frighten barred owls.11. What can be the best title for the text?A. Killing One Animal to Save Another.B. Keeping the Balance of Nature.C. Protecting Birds in Danger.D. Preventing Birds from Playing Fair.DAmerican football was the fastest-growing sport for US young players last year, according to a survey sponsored by the sport's governing body.But it was the game's no tackle variety that showed the biggest increase－a finding that may reflect concerns about injury. In American football, a tackle (抢断球) refers to an attempt to stop an opponent by forcing them to the ground.The number of participants in football grew in 2015 while most other sport, except baseball, posted a decline, USA Football said on Monday, citing(引用) the findings of a survey of 30,000 children and teenagers.Participation in flag football (a no-tackle type of football) increased by 8.7 percent among children aged 6 to 14, while tackle football rose by 1.9 percent. For that age group, the only other sport that grew was baseball, with a 3. 3 percent increase.In the 15-to-18 age group, flag football rose by 10. 5 percent, while tackle grew by 2.5 percent.Basketball was the third, with a 1. 1 percent increase. Participation in all other sports declined.Tom Farrey, executive director of the Aspen Institute's Sports & Society Program, said he was surprised that flag football participation rose so much.“The trend suggests that parents aremarching to the beat of a different drummer, in pursuing flagas an alternative for their kids," he said.The findings come at a time of increasing concern about the risk associated with youth sports, particularly hockey (曲棍球) and football, where medical researchers have warned about the risk of concussions (damagesto the brain caused by violent blows to the head) and death linked to brain injury.USA Football, anIndianapolis,Indianabased nonprofit funded in part by the National Football League, believed that the increases resulted from better safety and health education."Football participation increases, even modest increases, may signal that programs such as our Heads Up Football program and practice guidelines are making a positive difference," said Scot Hallenbeck, USA Football chief executive, in a statement.Robert Cantu, aBostonUniversityneurosurgery professor and investigator at the school's chronic Traumatic Encephalopathy (CTE) Center said the increase in fag football participation signaled that more parents were directing children to a safe alternative12. What can we learn about the two age groups?A. Flag football grew the fastest in the 6-to-18 group.B. Tackle football grew he fastest in the 6-to-14 group.C. Participation in baseball declined the most in both groupsD. Participation in tackle football increased the most in both groups.13. The underlined part probably means ________.A working at a different paceB. behaving in a different wayC. ignoring the major differencesD. trying to accept different opinions14. The popularity of flag football is inked with the fact thatA. its rules have been adapted for young playersB. it receives more funds than other varietiesC. tackle football is an old-fashioned gameD. experts worry about children's safety15. What is the cause of football growth according to USA Football?A. Their safety programs are successful.B. More children show interest in the game.C. Football is less likely to cause concussions.D. There are different types of football to choose from.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

The decision was announced during the online meeting of the UNESCO Intergovernmental Committee for the Safeguarding of the Intangible Cultural Heritage held from December 14 to19 inKingston, capital ofJamaica.“Born in the mid-17th century in a small village named Chenjiagou located in Central China's Henan province, Tai Chi is not only a kind of traditional Wushu integrated with slow movements and deep breathing, but is also deeply rooted in many areas of Chinese culture, such as medicine and philosophy,”Zhu Xianghua says, who is the son of the famous Tai Chi master Zhu Tiancai.Although it has spread to more than 150 countries and regions, attracting more than 100 million people to practice, the idea that Tai Chi is for the elderly has stopped many young people practicing the ancient Wushu. They think of it as a slow exercise, which is specially made and better suited for their grandparents. Instead, many young people are turning to the Indian practice of yoga（瑜伽）to relieve stress, which was placed on the UNESCO's List in 2019.In order to promote Tai Chi, joint efforts have been made from individuals and the Chinese government in the last decades. Xi'an Jiaotong University requires students to learn Tai Chi. Wang Yunbing, a professor in the university's sports center, stressed that Tai Chi is not only good physical exercise-researchers from the American College of Rheumatology find that it can help manage several diseases but is also conned ted to ancient Chinese eivilization. Since 2014, the World Tai Chi Championships have been held every two years by the International Wushu Federation.

Tai Chi Has Regained populate Globally.D. Opinions Greatly Differ on Tai Chi and Yoga.CScientists at the Massachusetts Institute of Technology (麻省理工学院) have turned spider webs into music——creating an strange soundtrack that could help them better understand how the spiders output their complex creations and even how they communicate.The MIT team worked with Berlin-based artist Tomas Saraceno to take 2D (two-dimensional) laser (激光) scans of a spider web, which were linked together and made into a mathematical model that could recreate the web in 3Din VR (virtual reality). They also worked with MIT’s music department to create the virtual instrument.“Even though the web looks really random (随机)，there actually are a lot of inside structures and you can visualize (可视化) them and you can look at them, but it’s really hard to grasp for the human imagination or human brain to understand all these structural details,” said MIT engineering professor Markus Buehler, whopresented the work on Monday at a virtual meeting of the American Chemical Society.Listening to the music while moving through the VR spider web lets you see and hear these structural changes and gives a better idea of how spiders see the world, he told CNN. “Spiders use vibrations (振动) as a way to locate themselves, to communicate with other spiders and so the idea of thinking really like a spider would experience the world was something that was very important to us as spider material scientists,” Buehler said.Spiders are able to build their webs without shelves or supports, so having a better idea of how they work could lead to the development of advanced new 3D printing techniques. “The reason why I did that is I wanted to be able to get information really from the spider world, which is very weird and mysterious,” Buehler explained. In addition to the scientific value, Buehler said the webs are musically interesting and that you can hear the sounds the spider creates during construction. “It’s unusual and eerie and scary, but finally beautiful.” he described.8. What have MIT scientists done according to the passage?A. They have translated spider webs into sounds.B. They have made a mathematical model to produce webs.C. They have created a soundtrack to catch spiders.D. They have known how spiders communicate.9. What can we know about spider webs from paragraph 3?A. Their structures are beautiful and clear.B. Professor Markus Buehler knows them well.C. The American Chemical Society presents the result.D. They are complex for people to figure it out.10. In which field will the study be helpful?A. virtual realityB. printingC. paintingD. film-making11. What is the main idea of the passage?A. It tells us that the music created by spiders is scary.B. It shows how the researchers carry out the experiment.C. It presents a new and creative way to study spiders.D. It explains why scientists did the experiment.DI was at my parent’s dinner table. Before me was a worn journal of thin and discolor1 ed pages. It was mygrandfather’s journal and now belonged to my father. My grandfather had passed away in the months leading up to my birth. I never got to visit the places he had frequented and the people who had been a part of his life’s journey.I was now about to enter his world, through the words he had left behind. Within minutes, I wascaptivatedby the power of the written words. In the magical script (笔迹) before me, I was transported to another age when food was an everyday art, planned, prepared and enjoyed in the company of others, and a time when people had the heart to pause their own lives to embrace (拥抱) each other’s struggles. All this was conveyed to me in the beauty of the words that flowed together to connect with the writer’s mind and understand the world they lived in.That kind of writing seems to be lost on us today. We have gotten used to writing in bite-sized pieces for a public looking for entertainment, and hungry for information. No wonder, there are nearly 200 million bloggers on the Internet and a new blog is created somewhere in the world every half a second. Instead of adding to our collective wisdom, most of these writings reflectthe superficiality (肤浅) and impatience of our day and age.This not only robs us of the skill of writing impressive essays, it also prevents us from exploring what is indeed important. Writing humbles (使谦卑) us in a way that is vital for our character growth, by reminding us about the limits of the self and our appropriate place in the vast flow of life. Writing frees us by helping us explore the unknown so that we really open up to magic of the world around us. I saw all of this in the writing of my grandfather. And I’ve seen it again and again in the writings of the greatest thinkers of humanity. Their writing reflect deep thought on issues of human importance.12. The underlined word “captivated” in the second paragraph can be replaced by “________”.A. puzzledB. frightenedC. attractedD. defeated13. In the author’s grandfather’s age, people ________.A. lived a hard lifeB. cared about each otherC. were fond of writingD. treated food as an art14. The author begins the text with her grandfather’s journal in order to ________.A. show her respect to her grandfatherB. present the importance of good writingC. express her interest in reading as well as writingD. raise the problems with today’s writing15. In the last paragraph, the author is trying to _________.A. discuss what good writing is likeB. express her strong desire to learn writing skillsC. stress the effects of her grandfather’s journal on herD. show her admiration for her grandfather’s writing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 such opportunities were becoming rarer due to the influence ofclimate change, the government agency, which has monitored the reef for 35 years, said in its annual report released today. “The increasing emergence of climate-related extreme weather events and starfish outbreaks is causing more severe and frequent pressures, giving the reef fewer opportunities like this to recover,”CEO Paul Hardisty said. The scientists surveyed 127 reef sites in 2021 and found hard coral cover had increased at 69 of the 81 locations surveyed in the past two years.Separate scientific research released last October found the 2, 300-kilometre (1, 400 miles) system had losthalf its corals since 1995, with a series of ocean heatwaves causing mass coral death.Britta Schaffelke, research program director at AIMS, said the latest findings provided a slight hope that the reef still has the power of recovering. But she added that its future is still very poor because of the dangers of climate change and other factors that are affecting the reef.UNESCO has urged Australia to take urgent climate action but the government has long resisted calls to commit to net zero emissions (排放) by 2050. The government has said it hopes to meet the target “as soon as possible” without harming its economy, insisting dealing with climate change requires a global effort. The reef was worth about US $4. 8 billion a year in tourism for the Australian economy and there are fears that an “in danger” listing could weaken its tourist appeal.4. What is the major cause of the damage to the corals?A. The climate change.B. Lack of money.C. Over development.D. Too many tourists.5. What is mainly talked about in Paragraph 3?A. The result of the survey.B. The efforts AIMS has made.C. The slight chance of the recovery.D. The terrible situation of the climate.6. What is Britta Schaffelke's attitude towards the future of the reef?A. Unclear.B. Positive.C Intolerant. D. Anxious.7. What can we infer from the last paragraph?A. Australia wants to put the reef on the endangered list.B. The Australian government has ignored UNESCO's demand.C. Australia hopes to keep a balance between emission target and its economy.D. The Australian government refuses to take its share of responsibility of climate change.CSome of my earliest memories involve sitting with my dad in his study every evening when he came home from the office. I’d watch as he put his personal items away: his watch, wallet, comb and car keys would always occupy the same spot on the table every time.Dad’s comb was bought when he married Mum. Every evening, he would smile, hand me the comb and say:“Be a good girl and help Daddy clean it, OK?” I was more than happy to do it. This seems amundanetask, but it brought me such joy at that time. I would excitedly turn the tap on, then brush the comb with a used toothbrush as hard as I could. Satisfied that I’d done a good job, I would proudly return the comb to Dad. He would smile at me, and place the comb on top of his wallet.About two years later, Dad started his own business. I started primary school. That was when things started to change. Dad’s business wasn’t doing so well, and he didn’t come home as much as he used to. Over the years, I stopped waiting for him to come home.Today, I’ve graduated from college and Dad’s business are better now. Yet the uncomfortable silence between Dad and me continued. Two days before my birthday last year, Dad came home early and said to me, “Hey, would you like to help me clean my comb?” I looked at him a while, then took the comb and headed to the sink. It’s a new comb. I hadn’t noticed that he’d changed it. I brushed the comb, and it hit me then: why, as a child, helping my dad clean his comb was such a joy.I passed the clean comb back to Dad. This time, I noticed my day has aged. But his smile is still as heartwarming as before. Dad carefully places his comb on top of his wallet. After so many years, I guess some things never change. And for that, I’m glad.8. As a child, the author helped her dad clean his comb happily because ________.A. she was good at cleaning the combB. she thought that she should do that as a good girlC. her dad was home early to spend the evening with herD. the comb was important for her father and her mother9. Which of the following words can best replace the underlined wordmundanein paragraph two?A. importantB. excitingC. unnecessaryD. uninteresting10. When the author said, “It’s a new comb. I hadn’t noticed that he’d changed it.”, she felt ________.A. disappointedB. impatientC. tiredD. sorry11. What’s the best title of the passage?A. Evenings With Dad.B. How to Clean the Comb.C. My Memory with My Dad.D. I Love My Family Members.DWhen Jennifer Doudna was in sixth grade, she came home one day to find that her dad had lefta book titled The Double Helix on her bed. She put it aside, thinking it was one of those detective tales she loved.On a rainy Saturday, she picked up the book. As she sped through the pages, she became fascinated by the drama, which encouraged her to explore nature's wonders. Even though her high school teacher told her that girls didn't become scientists, she decided she would.She worked with a biologist, Charpentier, to turn a curiosity of nature into an invention—an easy-to-use tool that can edit DNA. Known as Crispr, the tool will transform the human race. James Watson, the author of The Double Helix, later told her it was the most important biological advance: since he and Francis Crick discovered the structure of DNA.For this achievement, Doudna and Charpentier were awarded the Nobel Prize in Chemistry in 2020. Until now, only five women, beginning with Marie Curie in 1911, had won or shared the Nobel for Chemistry out of 184 award winners. When this year's prize was announced, Dr. Charpentier said it would provide a message specifically to young girls who would like to follow the path of science and to show them that women can also be awarded prizes.A few decades from now, if it becomes possible and sate to edit DNA, should we allow parents to improve the IQ and physical strength of their kids? Should we let them decide eye color1 ? Skin color1 ? Height? After helping to discover Crispr, Dr. Doudna has become a leader in considering these moral issues. That's the main message we should take from this Nobel: New technologies can be a huge benefit to the human race, but in order to make sure they are used wisely, it's important for people to understand them.12. Jennifer Doudna decided to become a scientist because,__________A. her father pushed herB. a book inspired herC. her teacher encouraged herD. James Watson motivated her13. Dr. Doudna was awarded the Nobel Prize because,__________.A. she wrote the book “The Double Helix"B. she discovered the structure of DNAC. she is a hardworking woman scientistD. she helped invent a tool for editing DNA14. According to passage, which of the following is NOT true?A. The two women's success will inspire more girls to be devoted to science.B. Since 1911, there have been 184 people who won the Nobel for chemistry.C. If girls follow the path of science, they will surely achieve their goals.D. Crispr will make a big difference to the human race.15. Which words can best describe Jennifer Doudna?A. Determined and responsible.B. Ambitious and humorous.C. Cruel and indifferent.D. Fearless and stubborn.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 few realize tiny bits of denim have been adding up to a surprising amount of pollution in water, as a new study shows.Sam Athey, one of the study’s authors, says, “Even though denim is made of a natural material—cotton, it contains chemicals.” Cotton fibers were treated with many types of chemicals, she notes. Some improve its durability and feel. Others give denim its distinctive blue color1 .Athey and her team washed jeans and found that about 50,000 microfibers came off from each pair per wash. Not all of those fibers make their way into the environment. Wastewater treatment plants catch about 83 to 99 percent ofthem. Catching 99 percent may sound pretty good. But one percent of 50,000 is still 500 fibers per wash. And since every pair of jeans is washed again and again, it still adds up to lots of microfibers entering the water environment.Denim microfibers showed up in sediment（沉淀物）from the Great Lakes. More of these fibers polluted a series of shallow lakesin southern Ontario. They even turned up in sediment from the Arctic Ocean in northern Canada. The team found denim accounted for 12 to 23 percent of microfibers in the sediment. There were other microfibers too. But the team focused on denim because so many people wear jeans.“Everyone wears jeans so they could be our largest input of microfibers into our streams and soils,” Athey says. “An easy way to limit that is by washing our jeans less often.” Athey grew up thinking she should wash her jeans after wearing them every couple of times, but most jean companies recommend washing them no more than once a month. “The solution is not that you shouldn’t wear jeans,” she says. “We need to buy fewer denim clothes and only wash them when they truly need it.”4. Which of the following is TRUE according to the passage?A. Chemicals are contained in natural cotton.B. Chemicals can make denim color1 ful.C. Chemicals prevent fibers from falling.D. Chemicals can make the life of denim longer.5. What does the underlined word “them” in Paragraph 3 refer to?A. Denim.B. Sediment.C. Microfibers.D. Chemicals.6. What does the author mainly want to tell us through Athey’s words ?A. To avoid wearing jeans.B. To reduce denim consumption.C. To wash jeans more often.D. To limit input in denim production.7. In which section of a magazine might the text be found?A. Science.B. Entertainment.C. Tourism.D. Geography.CHenry Cavill: Bring Superman to LifeHenry Cavill knew that he wanted to be a star at 16 years of age, after a chance meeting with movie star Russell Crowe who inspired hispassion for acting. But for the British-born actor, the bright lights and attraction ofHollywoodwere a long way away. Supported by his secretary mother and stockbroker father, he decided to study drama during high school. His journey to super star began.Before gaining the international recognition he has now, Cavill tried out for roles in the Harry Potter and Twilight series but failed to get either. He would have to keep waiting for his big chance.Determined as ever, Cavill took any acting jobs he could get his hands on and appeared in several low-budget horror movies and TV shows in hopes of getting noticed. It almost worked. In the early 2000s, at just 22 years old, he narrowly missed out on becoming the new James Bond. Finally, in 2007, his hard work paid off. He won a leading role as the first Duke of Suffolk in the period showThe Tudors. The TV show was very popular and helped to raise Cavill's popularity inAmerica.In 2011, Cavil landed his breakout role, playing Superman in the DC Extended Universe. He hasn't looked back and has since starred in many hit films, such asMission: Impossible- Fallout.More recently, he stepped back on to the small screen. Since 2019, he has starred in the popular seriesThe Witcher, adapted from the book series and video games of the same name. In the TV show, Cavill played a brave monster hunter named Geralt of Rivia, which was the perfect role for Cavill because he was a fan of the video games. Cavill also got a chance to play a classic English character — master detective Sherlock Holmes — in 2020'sEnola Holmes.However, Cavill isn't just a good guy on screen. His charity work also makes him a real-life hero. In 2014, he took part in the Ice Bucket Challenge while wearing his full Superman suit to support the ALS Association. Currently, he is an ambassador for the UK's Royal Marines Charity, which supports war veterans (退伍军人). Whydoes he do it? He love to make people feel good and bring smiles to people' faces. Indeed, Henry Cavill in living proof that you don't always need to wear a cape (斗篷) to act like a hero.8. Why did Cavil act in low-budget film and TV works early in his career?A. He was too polite to refuse.B. He was hoping to get noticed.C. He was encouraged to do so by his parents.D. He was friends with the directors of the projects.9. The role of the monster hunter was the perfect for Cavill because ________ .A. he had experienced hunting monstersB. he had played the same role in a movieC. he knew the writer of the books personallyD. he enjoyed the video games that the show was rooted in10. Which of the following words can best describe Cavill?A. Modest and friendly.B. Determined and kind.C. Talented and faithful.D. Honest and considerate.11. What made Cavill a real-life hero?A. Being a successful actor.B. Playing Superman on screen.C. Devoting to charities.D. Wearing a cape to take part in activities.DPlanned missions to the moon need to hurry up to avoid hitting one of the busiest periods for extreme space weather, according to scientists conducting the most in-depth ever research on solar storm timing.Scientists at theUniversityofReadingstudied 150 years of space weather data to look into patterns in the timing of the most extreme events,which can be extremely dangerous to astronauts and satellites. This new research on space weather timing allows predictions to be made for extreme space weather. Therefore, it could be used to plan the timing of activities, which could be affected by extreme space weather, for example, major space missions.The researchers found for the first time that extreme space weather events are more likely to occur early in or late solar cycles-such as the one just starting. The findings may have influences on the NASA-led Artemismission. It plans to make humans return to the moon in 2024, but can be put off to the late 2020s.Professor Mathew Owens, a space physicist at theUniversityofReading, said, “Until now, the most extreme space weather events were thought to berandomin their timing. Though there is no set pattern of the events, this research suggests they are more predictable.”In the new study, the scientists used a new method applying statistical modelling to storm timing for the first time. Previous research generally focused on how big extreme space weather events can be, based on observations of previous events. Predicting their timing is far more difficult because extreme events are rare, so there is ly little historic data to identify patterns. The findings suggest that any major planned space missions , which is beyond the next five years, will have to consider the higher probability of extreme space weather late in the present solar cycle between 2026 and 2030.12. What can we learn about the study from the first two paragraphs?A. It has lasted just 150 years.B. It doesn't refer to space weather data.C. It shows space weather has no effect on astronauts.D. It makes it possible to predict extreme space weather.13. Why might the NASA-led Artemis mission be put off?A. To research solar cycles.B. To avoid effects of space weather.C. To meet the needs of the astronauts.D. To make humans return to Earth in 2024.14. What does the underlined word “random“ in paragraph 4 probably mean?A. Irregular.B. Easy.C. Limited.D. Changeless.15. What can we infer from the last paragraph?A. The study is useful for future space missions.B. The planned space missions should be put off.C. Extreme space weather will happen before 2026.D. Previous observations make no difference to the study.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。

Had I not seen three bears and a few wolves over the last couple of days near the road, I might have just lain down and called it quits. What in the world was I thinking, dragging my bike up to Yellowstone and thinking I could ride from West Yellowstone to Old Faithful in the snow? No less!I had planned this trip for more than two months, and I wasn't about to give up so easily. The first few miles were beautiful. Ten miles in, I started sucking wind. Fifteen miles and my legs felt like they were made of lead. By twenty miles, my lungs were burning and felt like there was nothing left in the tank. That was when I turned around and saw my husband and three children cheering me on in the van behind me. I knew I couldn't quit because I tell my children all the time that just because something is hard doesn't mean that you stop doing it. I had to live what I'd been preaching(说教). That thought got me up that mountain and to the end of the ride.The importance of that ride was apparent after only a week. My eight-year-old daughter Emalee wanted to ride in a twelve-mile charity ride. That day was cold as well. She was the youngest rider. About four miles into the ride, she started feeling cold. The chill(寒冷)was making her muscles cramp a little and she began to struggle. By six miles, she had tears running down her face. It broke my heart to see her suffering like that.I told herthat she didn't have to finish. She said that she wouldn't quit. I told her how I had wanted to quit the week before, but perseverance had gotten me to the end and I knew she could do it, too.The look on her face as she pulled into the finish was priceless. She threw her arms around me and said, “You didn't quit, Mommy, so neither did I.”1. What motivated the author to finish her ride?A. Her family's encouragement.B. Her own instruction for children.C. The beautiful scenery and weather.D. The careful and thorough preparation.2. By describing the conditions Emalee met, the author wanted to________.A. show her guilt for her daughterB. prove that riding is a tough taskC. persuade her daughter to give upD. indicate she was proud of Emalee3. What does the author want to tell us according to the story?A. Never say die.B. Do nothing by halves.C. Children are what the mothers are.D. Every mother's child is handsome.BWhen I was a boy, there was but one permanent ambition among my comrades in our village on the west bank of Mississippi River. That was, to be a steamboat man. We had temporary ambitions of other sorts, but they were only temporary.My father was a justice of the peace, and I supposed he possessed the power of life and death over all men and could hang anybody that offended him. This was distinction enough for me as a general thing；butthe desire to be a steamboat man kept intruding, nevertheless. One of our boys in town, who went away and was not heard of for-a long time, turned up as apprentice engineer on a steamboat. This thing shook the bottom out of all my Sunday—school teachings. That boy was notoriously worldly, and I was just the opposite. There was nothing generous about this fellow in his greatness. He would always manage to have a rusty nail to scrub while his boat stopped at our town, and he would sit on the inside guard and scrub it, where we could all see him. And wherever his boat was laid up he would come home and show off in the town in his blackest and greasiest clothes, so that nobody could help remembering that he was a steamboat man; and he used all sorts of steamboat technical terms in his talk, as if he were so used to them that he forgot common people could not understand them.This creature's career could produce but one result, and it was speedily followed. Boy after boy managed to get on the river. Despite many choices, pilot was the grandest position of all. The pilot, even in those days of trivial wages, had a princely salary—from 150—250 dollars a month, and no board payment.But our parents would not let us and our worry was the next year would find us hunting for jobs with low pay again. So by and by I ran away. I said I never would come home again till I was a pilot and could come in glory.4. Why does the writer mention his father's job in Paragraph 2?A. To show that his father was in power.B. To show that his father is cruel.C. To emphasize the job he prefers.D. To emphasize his love for his father.5.

He thought the boy was shallow but knowledgeable.D. He thought the boy was disrespectful but still liked him.6. Which of the following statements is Not True?A. The boy talked in a way to make others feel jealous.B. The boy's experience made other boys follow suit.C. The pilot's salary was ly high but without meals covered.D. The writer was ambitious to make his childhood dream come true.7. What rhetorical method does the underlined sentence have?A. Simile.B. Personification.C. Parallelism.D. Irony.CI was so worried about handing my little boy over during his first week of school, but you made it easier. You smiled at him like a mother would at her own child.You showed warmth and your hugs were always on offer.After a day in class with you, Charlie would come home singing. Whenever I hear Do Your Ears Hang Low or see him stretching to the sky when singing about the days of the week, I will think of you.I didn't tell you at the time, but I loved your morning song so much that Iimplementedit in my own class (I'm a teacher, too).When you saw I was troubled, you hugged me with your smile and I knew everything would be OK. You made parents feel as cared for as our children.In the short time I knew you; you taught me about the type of teacher I desire to be. You never seemed disturbed by the mountain of paperwork or impossible work-life balance that comes with the role. Instead, you appeared to embrace every minute.I can't understand why you've been taken from us. Telling Charlie was one of the hardest things I've had to do.I'm not sure he fully understands, but he told me he loved you and has been asking whether your"robot powers"will work in heaven.A friend once told me white feathers are angels telling us that loved ones in heaven are well. On the first day collecting the children without you，a white feather floated through the sleet (雨夹雪). Watching the younger ones bounce and gigle as they tried to catch it was beautiful.I wish I had told you all of this when you were with us.I hope that you knew how you brought happiness to everyone you met and how loved you were. Goodbye, Dear Friend.8. What does the underlined word "implemented" in Paragraph l probably mean?A. Looked back on.B. Looked forward to.C. Thought highly of.D. Made use of.9.

But Chris Roh and other researchers at the California Institute of Technology found that when bees drop into bodies of water, they can use their wings toproduce little waves and slide toward land-like surfers who create and then ride their own waves.As with many scientific advances-IsaacNewton’s apple or Benjamin Franklin’s lightning bolt-Dr. Roh’s experiment began with a walk. Passing Caltech’s Millikan Pond in 2016, he observed a bee on the water’s surface producing waves. He wondered how an insect known for flight could push itself through water.Dr. Roh and his co-worker, Morteza Gharib, used butterfly nets to collect localPasadenahoneybees and observed their surf-like movements. The researchers used a wire to restrict each bee’s bodily movement, allowing close examination of their wings. They found that the bee bends its wings at a 30-degree angle, pulling up water and producing a forward force. Bees get trapped on the surface because water is roughly three times heavier than air. But that weight helps to push the bee forward when its wings move quickly up and down. It’s a tough exercise for the bees, which the researchers guess could handle about 10 minutes of the activity.The researchers said the surf-like movement hasn’t been documented in other insects and most semiaquatic insects use their legs forpropulsion, which is known as water-walking. It may have evolved in bees, they-predicted.Dr. Roh and Dr. Gharib have imagined many practical applications for bees’ surfing. One plan is to use their observations to design robots able to travel across sky and sea. “This could be useful for search and rescues, or for getting samples of the surface of the ocean, if you can’t send a boat or helicopter,” Dr. Gharib said.12. What does the author intend to show by mentioningNewtonandFranklin?A. Roh’s admiration for them.B. Roh’s chance discovery about bees.C. Their outstanding talent for science.D. Their similar achievements in discovery.13. What plays the most vital role in a bee’s moving forward on water?A. The air weight.B. Its leg extension.C. The water movement.D. Its continuous wingbeat.14. What does the underlined word “propulsion” in Paragraph 4 mean?A. Fast flightB. Driving force.C. Pulling speed.D. Explosive power.15. What does the text mainly tell us?A. Honeybees can surf to safety.B. Bees help scientists make inventions.C. Insects can adapt to the environment.D. Nature is a helpful guide for discovery.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。

I remember one night after a long, hard day at work, my mom placed a plate of eggs, sausage, and a plate of extremely burnt biscuits on the table. I waited to see if my dad would get annoyed.All my dad did was to reach for the biscuits, smile at my mom and ask me how my day at school had been. I don't remember what I told him that night but I do remember watching him add butter and jelly on that ugly burnt biscuit and ate every bite of that thing. He never made a face nor uttered a word about it!When I rose from the table that evening, I remember hearing my mom apologize to my dad for overcooking the biscuits and I will never forget what he said, “Honey, I love burnt biscuits every now and then."Later that night, I went to say good night to my daddy, and I wondered if he really liked his biscuits burnt. He wrapped me up in his arms and said gently, "Your mom put in a hard day at work today and she is really tired. Besides, a little burnt biscuit never hurt anyone!As I have grown older, I've thought about that many times. Life is full of imperfect things and imperfect people. Learning to accept each other's faults and choosing to celebrate each other's differences contribute to a healthy, growing, and lasting relationship. We could extend this philosophy to any relationship, such as a husband-wife, parent-child, or friendship. Don't put the key to your happiness in someone else's pocket. Keep it in your own.

The battle scenes and the exciting rescues of people who are dying interested him greatly.There was just one problem: Tristin was only 9 years old, and it was thought that movie was not for children. When his parents caught him watching it on TV, they made him turn it off, though he had finished his homework and it was not late. Then one day, Tristin and his family were visiting his grandmother inMesa,Arizona. Tristin’s 2-year-old sister got out of the house and fell in the backyard pool.

The family called the ambulance, but no one knew how to do first aid. No one, that is, except for Tristin. A scene in “Black Hawk Down” describes a doctor giving first aid. Tristin remembered it. Then the 9-year-old gave first aid to his sister at once and saved her life.His parents don’t stop him seeing the movies he likes any more.Tristin taught himself how to do first aid but he had never thought he could use it to save his little sister’s life.

Department of Homeland Security recommends having at least a two - week supply of water and food.PotatoesShelf life：2 to 5 weeks if stored in a cool, dry, dark placeYukon Gold, red, and fingerling potatoeswill last from two to three weeks. Larger white potatoes can last for three to five weeks. Sweet potatoes have about the same shelf life. Don't store them next to onions, however. The two might go together well in cooking, but raw, each gives off gases and moisture that might cause the other to spoil faster.Tea※Shelf life：6 to 12 months past "sell - by" dateDried tea leaves, whether loose (in a sealed container) or in teabags (in an unopened box) can easily last a year or more if they' re not subjected to damp or humidity. However, the tea does tend to lose flavor over time.Peanuts● Shelf life：1 to 2 monthsPeanuts in their shell, especially when kept cool and dry, are perfectly happy in the cupboard for as long as two months.Canned fruits and vegetables● Shelf life：1 to 2 years past "sell - by” dateCanning is an extremely efficient means of preserving food. Generally speaking, if canned foods aren't subjected to extreme heat, their contents should stay good for two years or more. Be aware, however, of dented cans or those with swollen tops, which may indicate the presence of bacteria inside.1. Which can go bad faster if stored with onions?A. Potatoes.B. Tea.C. Peanuts.D. Canned fruits and vegetables.2. What is special about tea?A. The flavor of tea can always remain the same.B. Tea leaves are better to be preserved in an open jar.C.

He recently completed his bachelor's degree(学士学位) which he started in1995.Montefiore left university in 1996 and tried to tell himself that a degree wasn't necessary for personal success. But it remained unfinished businessuntil he made the decision to return in 2018 at the age 42. At that time, his job development stalled, so he made up his mind to go back to school in order to improve himself and work well in future.The second time around, Montefiore never missed a class and always sat in the front row. He found many courses invaluable and he received the Award of Excellence twice. He found support services played an important role in his successful return. He said, “I hadn't written a paper for years, so I found the college writing centre to be of great use. Before I handed in a paper, they would give me feedback, which was really great. The university has so much built in to help students succeed and I'm so thankful for that.” But he also met difficulties this time. As a student much older than others, he found it harder to make friends with classmates.However, no matter what had happened before, he finally got his bachelor's degree. He said, “After all these years, I had thought it wouldn't mean anything, but it means a lot. I totally understand the value of education now. It's not necessarily the value that other people see in it, but the value it gives me as a person, for my confidence and my self-esteem. It also helps me prepare well before I re-enter the workplace.”4. Why was Montefiore's graduation unusual?A. He had achieved personal success before.B. He understood the importance of a degree.C.

What if your trash could become your own treasure? Many creative, thrifty, and environmentally minded people have come up with a way to makethathappen. It’s called upcycling. Our world would be a better place if everyone would begin upcycling.Upcycling is the practice of taking an unwanted item and turning it into something useful. For example, how about that pair of jeans with a hole in one knee? It could become a new pillow for your bedroom.Upcycling is not the same as recycling. Upcycling is actually much better for the environment. Recycling takes an item made of glass, paper, metal, or plastic, breaks it down to its base material, and then uses that material to make another product. This requires a great deal of energy. On the other hand, when you choose to upcycle, the only energy you use is your own. And upcycling not only reduces the amount of trash that goes into our landfills, but it also protects natural resources, such as oil and gas. Recycling is good for the environment, but upcycling is even better.Upcycling also makes a family’s budget stretch further. Of course, the idea of reusing items to save money is not new. During the Great Depression in the 1930s, many families lived on a tight budget. People had to use what they already had in order to meet their needs.As responsible citizens, we should all be concerned with protecting our environment and budgeting our resources. Upcycling is a fun and creative way to help. The next time you go to toss something into the trash can, stop and think about what it could become. Chances are, there’s a brand-new item in your hand just waiting to be upcycled.8. Why does the author mention an old saying in the first paragraph?A. To arise reader’s awareness of upcycling.B. To stress the importance of upcycling.C. To lead in the topic of upcycling.D. To show the idea of upcycling.9. Which one below belongs to upcycling?A. An old ladder is transformed into a bookshelf.B. Old tin cans are transported to landfill.C. A broken wooden door is chopped up.D. Old cloth is made into a paper bed.10. What is the difference between recycling and upcycling?A. Upcycling is much more creative.B. Recycling is much easier to achieve.C. Recycling is much more cost-saving.D. Upcycling is much more energy-efficient.11. What can be inferred from the text?A. Upcycling is popular at present.B. Upcycling is replacing recycling.C. Upcycling is worth recommending.D. Upcycling is a tradition in daily life.DDengue is a very painful illness spread by mosquitoes. In severe cases, dengue can even be deadly. Dengue is a serious disease affecting people in around 120 countries. It can cause high fevers, headaches, and severe pain. It’s caused by a virus spread by bites from mosquitoes. Therefore, dengue is more common in warm areas. Every year, roughly 390 million people get dengue, and as many as 25,000 die from it.Now scientists seem to have found a way to protect humans from dengue by first protecting mosquitoes. Dengue fever is caused by a virus. Though it may seem strange to think of it this way, the mosquitoes that spread the dengue virus are also infected with it. But the virus doesn’t seem to hurt the mosquitoes.Wolbachia is a kind of bacteria commonly found in many insects. In some insects, Wolbachia can keep some viruses fromduplicatingthemselves, which is how viruses grow inside a body. Wolbachia isn’t naturally found inmosquitoes. But by infecting these mosquitoes with Wolbachia, scientists can keep the mosquitoes from catching the dengue virus. Even better, the young mosquitoes coming from the eggs of the infected mosquitoes also carry Wolbachia.Researchers working with the World Mosquito Program (WMP) ran a 27-month study in Yogyakarta, Indonesia. They split a 10-square-mile area up into 24 smaller areas. In half of the areas, the scientists did nothing. In the other half, they set out containers of eggs from mosquitoes that had Wolbachia. They did this every two weeks for just 4 to 6 months.Ten months later, 80% of the mosquitoes in the treated areas carried Wolbachia. The researchers report the number of dengue cases in the treated areas was reduced by 77% and that the number of people needing hospital care for dengue dropped by 86%.Because the results of the experiment were so good, the WHO has placed Wolbachia-infected mosquito eggs in all parts of Yogyakarta and surrounding areas. The WHO says that within a year, their efforts will protect 2.5 million people against dengue and that their efforts will be turned into a program that can be repeated worldwide.12. What kind of disease is dengue?A. It is likely to cause death.B. It causes no pain but fevers.C. It happens less often in hot areas.D. It hurts both people and mosquitoes.13. The underlined word “duplicating” in paragraph 3 most probably means “________”.A. worsening the harm ofB. expanding the size ofC. increasing forces ofD. making copies of14. What can be inferred about the method from the figures listed in paragraph 5?A. Its wide use.B. Its effectiveness.C. Its complexity.D.Its easy operation.15. What’s the WHO’s attitude towards the method?A. Ambiguous.B. Positive.C. Tolerant.D. Skeptical.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。

How can this problem be solved. Some suggestions have been to desalinate ocean water or to build enormous water pipelines from areas where water is abundant. (Suggestions such as these prove extremely expensive when they are actually used.) One possibility that scientists are considering is pulling icebergs from either the North Pole or the South Pole to parts of the world with a water shortage. Although many questions must be answered before such a project could be tried, moving icebergs seems a reasonable possibility in the future.Engineers, mathematicians, and glaciologists from a dozen countries have been considering the iceberg as a future source of water. Saudi Arabia is particularly interested in this project because it has a great water shortage. Scientists estimate that it would take 128 days to transport a large iceberg (about 1/2 square mile) to Saudi Arabia. Yet the iceberg would be completely melted by the 104th day. Therefore, insulation would be essential, but how to insulate the iceberg remains an unsolved problem.The problems in transporting an iceberg are numerous. The first problem is choosing the iceberg to pull. The icebergs that form in the North Pole are quite difficult to handle because of their shape. Only a small portion extends above the water — most of the iceberg is below the surface, which would make it difficult to pull. South Pole icebergs, on the other hand, are flat and float like table tops. Thus they would be much easier to move.How can a 200-million-ton iceberg be moved. No ship is strong enough to pull such enormous weight through the water. Perhaps several ships could be used. Attaching ropes to an iceberg this size is also an enormous problem. Engineers think that large nails or long metal rods could be driven into the ice. What would happen if the iceberg splits into several pieces during the pulling. Even if an iceberg with very few cracks were chosen, how could it be pulled through stormy waters. Furthermore, once the iceberg reached its destination, very few ports would be deep enough to store it.All of these problems must be solved before icebergs can become a reasonable source of water. Yet scientists estimate that it will be possible to transport them in the near future. Each year, enough icebergs form to supply the whole world with fresh water for a full year. In addition, icebergs are free and nonpolluting. As a solution to the world’s water problems, icebergs may be a workable possibility.4. What is a problem in transporting iceberg?A.

Iceberg—scientists headache.CAs summer approaches, many kids and teenagers may find that they have more time in hand. One great way to make use of the extra time is to go on an adventure and travel. Clearly, I am not a naturally adventurous person, but I have found that takingthe risk and challenging myself to explore and travel to unfamiliar places can be a very rewarding experience.Because I am usually quite busy during the school year, most of my travels take place during the summer. Over the past few summers, I have hiked in the Grand Canyon, explored Niagara Falls, and camped out in upstate New York. Although these experiences are varied, they are similar in that they instill (灌输) a sense of appreciation for nature and a more balanced view on life. When I hiked in the Grand Canyon, for example, I was in awe(敬畏) of the geological influences that shaped the canyon.Adventures, of course, are not limited to hiking. There are many other choices, such as camping, volunteering in a foreign environment and travelling to different countries. In my opinion, adventures are more enjoyable with family or a few friends. There is a sense of bonding that one only gets through spending time together in outdoor adventures. For example, when I was in Boy Scouts, I often went on weekend camping trips with my friends. When I came back from a Boy Scouts camping trip, I often was eager to go outside more and explore the parks and nature around me.Next fall, I will attend college. In the meantime though, I hope to make the most of my summer to explore and travel. Now, I am planning on hiking and camping out in Maine.When I visited Maine last fall, I was amazed by how beautiful it was and the tall trees and coasts that exist, and I really hope to enjoy the beauty of nature there this summer.8. We can learn from the first paragraph about the author?A. He is an adventurous person by natureB. He likes challenging himself by travellingC. He enjoys travelling with other adventurersD He needs others’ help when going on an adventure9. Which of the following can make people’s adventure more enjoyable according to the author？A. Going to different countries.B. Going to unfamiliar places.C. Travelling withtheir family or friends.D. Travelling to distant places by themselves.10. What will the author do this summer？A. Explore Niagara Falls.B. Hike in the Grand Canyons.C. Camp out in upstate New York.D. Hike and camp out in Maine.11. Who is probably the author?A. A high school student.B. A college student.C. A friendly guide.D. A warm-hearted teacher.DGuangzhououtbreak linked to strains inIndiaThe gene sequencing of the COVID-19 outbreak inGuangzhou.Guangdongprovince, indicates it is very similar in structure to the mutatedstrains detected inIndia, a senior health official from the city said on Sunday.“And it has the characteristic of quick spread.” Chen Bin, deputy director of the city's health commission, said at a news conference inGuangzhouon Sunday.She urged relevant departments and medical staff to act quickly to block the chain of infection and control the spread of the coronavirus in the southern metropolis.Zhang Zhoubin, deputy director of theGuangzhoucenter for disease control and prevention, said the strain of coronavirus spreads easily.“The virus can be spread through a meal or through a short period of indirect contact,” he said.The city reported five confirmed eases and 21 asymptomatic carriers as of 2 pm Sunday after the first confinned case was detected in the city's Liwan district on May 21, Chen said.To prevent the virus from spreading, the city government tightened its disease control and prevention measures over the weekend.

2020届重庆市经开礼嘉中学校高三英语下学期期中考试试卷及参考答案

2020届重庆市经开礼嘉中学校高三英语下学期期中考试试卷及参考答案第一部分阅读（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AThe Fall 2020 Cookbooks Worth Your Time (and Money)Be My GuestFrom Priya Basil, this book is a self-reflection on how food and the act of serving it are used to express love and support. Basil reflects on some of her earliest memories of food and how it affected her upbringing and relationship with her parents. Now a parent herself, she centers food in her book's exploration of that change of identity.EastFrom Guardian columnist Meera Sodha comes a cookbook centered on vegetables. The book features recipes that cover a variety of Asian cuisines. Sodha showcases the diversity of vegetarian cooking with dishes like eggplant larb mushroom bao, Singapore noodles and so much more.I Cook in ColorA follow-up from her first cookbook My Two Souths, Asha Gomez focuses on the rainbow of vegetables to create desserts and cross-cultural dishes that associate cooking traditions of her mother's Keralite kitchen and Gomez's travel experiences.Time to EatIf you're a fan of The Great British Baking Show and Nadiya Hussain's Netflix series, you'll be just as excited for the American release of this book of time-saving tips for home cooks on a budget. It's a book to go to for inspiration that doesn't involve countless hours of sweating over a hot stove.1.What can we learn about the author ofBe My Guest?A.She had a bad relationship with her parents.B.She began to cook food in her early childhood.C.She considers food a means of expressing affection.D.She explores in the book how to be a grandparent.2.What do theEastandI Cook in Colorhave in common?A.They offer recipes about Asian cuisines.B.They center on cooking vegetables.C.They are the author's first cookbooks.D.They are based on the author's travel experiences.3.Which book can you refer toif you just have limited time for cooking?A.Be My Guest.B.East.C.I Cook in Color.D.Time to Eat.BTo hear people talk about Internet friendships, you would think it was one giant web of cat-fishing and e-crime. While we all undoubtedly have to take measures to remain safe online, assuming every friendship or connection made on Instagram, Twitter or Facebook is cheating or insincere would be a mistake.As a woman who works in the creative industry, I have found real joy in seeking out a community I couldn’t find elsewhere, and making some great friends along the way. My first online friendship was on Twitter with my(now) best friend, during the university exam period. We exchanged study notes in dozens of direct messages, set a study date, and haven’t looked back since.Drawn to each other by similar circumstances, friendships online are similar to offline in that they tend to begin because of shared interest or common ground-maybe they’ve read the post on Instagram. Maybe they have the same taste in food or politics. Or maybe they just love memes too. If online friendships start similar to friendships offline, they grow in the same way, too. Often through mutual support: apart from calling a friend to congratulate him on that new job, you also re-tweet his jokes and praise his Instagram story.Despite my positive experiences when I tell people, most are still suspicious. Eyebrows are raised higher when I explain not only have I found a community online but have made friendships with people I meet face-to-face too. Actually, these are just as valid as other friendships, according to behavioural psychologist Jo Hemmings, who says online friendships can be real.So how do you know if people are there for the real you or just because you’re popular on Instagram? Hemmings has simple rules. She tells me “You have to equally feel comfortable that you’re getting something of each other instead of being used to enable something that isn’t friendship.”Therefore, if all a “friend” online is asking you to do is to promote their work or personal brand and rarelytakes an interest in you, then there may be room to question the basis of the friendship. On that note it is worth remembering that just because someone has a lot of followers, it doesn’t necessarily mean they have lots of friends.4. What is most people’s attitude towards online friendship?A. Negative.B. Positive.C. Objective.D. Neutral.5. Why does the writer share her own experience in paragraph 2?A. To introduce the background information of the text.B. To convey the writer’s attitude and give the related example.C. To prove the likely risk for people to develop friendship online.D. To remind people of the various benefits of making friends online.6. How can online and offline friendships be deepened?A. They should be based on shared interest.B. They need to have common ground.C. They require support from each other.D. They can’t live without social media.7. According to the author, what’s the golden rule to make friends online?A. A friend to all is a friend to none.B. Without confidence there is no friendship.C. A friend without faults will never be found.D. Friendship cannot stand always on one side.CThis 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 hejust 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 people had 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.DBecause of COVID-19, in many places, large gatherings of people aren’t allowed. In some areas, the rules are more strict, and people aren't allowed to leave their homes unless going out is ly necessary.These steps are very important for slowing the disease down. By doing this, governments can make sure doctors and hospitals are better able to deal with all the sick people, and that fewer people suffer in all. Usually, it's called “flattening the curve”.But if no one can go out, that means businesses which depend on visitors struggle. Many singers, bands, and other musicians would normally be giving concerts now. Instead, they have to find new ways to share their music and connect with their audiences. The Metropolitan Opera in New York has canceled(取消) its season, but it is showing a special live stream of a different opera each day on its website. Other opera companies have made similar moves. Several theater companies are either offering recorded versions of their plays online or posting videos of their actors performing.Nick Green wrote a musical play that was canceled because of the virus. He set up a website with links that allow people to enjoy the work of artists around the world who have had their projects canceled. He called his project the Social Distancing Festival. He sad it was a time when he should be doing something new, rather than feeling disappointed.Even TV shows have to find new ways to film their shows. Some late night TV shows have continued, but without audiences. Others are showing reruns.While their shows are on pause, some TV stars like Conan O’Brien and Jimmy Fallon have been filming short videos at home. Mr. O’ Brien plans to bring his show back on the air soon by filming with his own phone and talking with guests over the Internet.12. What does the underlined phrase in Paragraph 2 refer to?A. Keeping patients staying at home anytime.B. Speed up the spread of disease.C. Stopping people from often gathering up.D. Slowing down the spread of the disease.13. What are opera companies’ new ways?A. Stopping sharing music with audience.B. Providing live stream services.C. Trying to attract live audiences.D. Sharing their operas with each other14. What did the cancellation of Nick Green's play bring him?A. Disappointment.B. Annoyance .C. Creativity.D. Anxiety.15. What is the text mainly about?A. People staying at home .B. The absence of audiences.C. The efforts of Nick Green .D. Entertainment going online .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。

Imaginate FestivalC. The RoyalEdinburghMilitary TattooD.EdinburghInternational Film FestivalBHoneybees can’t swim, and when their wings are wet, they can’t fly, either. But Chris Roh and other researchers at the California Institute of Technology found that when bees drop into bodies of water, they can use their wings toproduce little waves and slide toward land-like surfers who create and then ride their own waves.As with many scientific advances-IsaacNewton’s apple or Benjamin Franklin’s lightning bolt-Dr. Roh’s experiment began with a walk. Passing Caltech’s Millikan Pond in 2016, he observed a bee on the water’s surface producing waves. He wondered how an insect known for flight could push itself through water.Dr. Roh and his co-worker, Morteza Gharib, used butterfly nets to collect localPasadenahoneybees and observed their surf-like movements. The researchers used a wire to restrict each bee’s bodily movement, allowing close examination of their wings. They found that the bee bends its wings at a 30-degree angle, pulling up water and producing a forward force. Bees get trapped on the surface because water is roughly three times heavier than air. But that weight helps to push the bee forward when its wings move quickly up and down. It’s a tough exercise for the bees, which the researchers guess could handle about 10 minutes of the activity.The researchers said the surf-like movement hasn’t been documented in other insects and most semiaquatic insects use their legs forpropulsion, which is known as water-walking. It may have evolved in bees, they-predicted.Dr. Roh and Dr. Gharib have imagined many practical applications for bees’ surfing. One plan is to use their observations to design robots able to travel across sky and sea. “This could be useful for search and rescues, or for getting samples of the surface of the ocean, if you can’t send a boat or helicopter,” Dr. Gharib said.4. What does the author intend to show by mentioningNewtonandFranklin?A. Roh’s admiration for them.B. Roh’s chance discovery about bees.C. Their outstanding talent for science.D. Their similar achievements in discovery.5. What plays the most vital role in a bee’s moving forward on water?A. The air weight.B. Its leg extension.C. The water movement.D. Its continuous wingbeat.6. What does the underlined word “propulsion” in Paragraph 4 mean?A. Fast flightB. Driving force.C. Pulling speed.D. Explosive power.7. What does the text mainly tell us?A. Honeybees can surf to safety.B. Bees help scientists make inventions.C. Insects can adapt to the environment.D. Nature is a helpful guide for discovery.CKamikatsu, a small town in Japan, has shown the world that our garbage has far-reaching effects, and not just on our environment.Theexperiment in going zero waste started when the town built a new incinerator 20 years ago. But almost immediately, the incinerator was determined to be a health risk due to the poisonous gases when garbage was burned in it. It was too expensive to send waste to other towns, so locals had to come up with a new plan. Then the Zero Waste Academy was born, which helped perform this plan.Now Kamikatsu people separate their waste into 45 different categories. But in the beginning, it wasn't easy to convince local people to do all this work, and there was somepushback. Only after that initial education period did most residents come on board.This is all great news for waste reduction of course, but it has also had some unexpected social benefits as well. Like much of Japan, Kamikatsu's population is aging, and about 50 percent of the locals are elderly. The fact that the whole community takes their trash in to be recycled has created a local action and interaction between generations.That idea has been purposefully expanded to include a circular shop where household goods are dropped off and others can take them, and a tableware "library" where people can borrow extra cups, glasses, silverware and plates for celebrations."The elderly see this not as a waste-collection service, but an opportunity to socialize with the younger generation and to chat. When we visit them, they prepare lots of food and we stay with them for a while, we ask how they are," Sakano, the founder of the Zero Waste Academy, said.Sakano's ideas are truly revolutionary if you think about it. She's proving that community can be found through handling the stuff we no longer want and need.8. What is mainly talked about in paragraph 2?A. What harmful effects garbage burning has.B. Why garbage sorting is necessary in Japan.C. How the idea of zero waste was put forward.D. What the Zero Waste Academy functions as.9. What does the underlined word "pushback" probably mean?A. Inactive response.B. Generous reward.C. Bitter suffering.D. Beneficial guidance.10. What is a bonus of the zero waste project?A. Reducing waste.B. Creating community.C. Increasing people's income.D. Developing a new technology.11. Which part of a newspaper is this text most likely from?A. Technology.B. Health.C. Workplace.D. Lifestyle.DWe have most friends at the age of 26 afterhaving spent the first quarter of our lives building up our friendship circle, new research has claimed.The research into friendship shows that our social circle peaks at 26 years and 7 months, at which we typically have five close friends. Women are most popular at 25 years and 10 months, with men hitting the highest friendship point a little later at 27 years and 3 months.The research, by Forever Friends, shows that about a third of adults meet their closest friends while at school, with about a fifth saying they meet them at work.Social networks such as Facebook and Twitter now also play a major role in building new friendship. The research points out that 25 to 34-year-olds make 22 friends via Facebook, compared to 18 to 24-year-olds who make 12, and 35 to 44-year-olds who make just four.Forever Friends' relationship coach Sam Owen says, “It is no coincidence that over a third of us meet our best friends at school. It is a key time in our lives when friendship is growing through sharing notes, giving gifts, seeing each other regularly and laughing a lot. As adults we can often forget how powerful these small things are and how the little things can make a difference."Later in life we find ourselves losing friends. Over half of us lose friendship through moving, while 36% say that over time they grow apart from close pals. Having children also causes 19% todrift away fromchildhood friends.With growing pressure being put on friendship these days, it's important to make time for our friendship.12. How many friends can a 20-year-old college student make via Facebook?A. 22.B. 18.C. 12.D. 4.13. In Paragraph 5, the author is trying to tell the readers ________.A. how important making friends isB. school time is an important period to develop friendshipC. how much has been done to keep friendshipD. that friendship is not easy to keep14.

It started with the Curtiss Autoplane of 1917, an awkward-looking machine with removable wings. It never left the ground. Later machines made it into the skies but failed to take off commercially. Money is now pouring into flying taxis. On March 30th Lilium, a German company that develops them, announced a merger with SPAC, an acquisition company that values it at $3. 3 bn -- a sign that investors think the business will fly.Thanks to better batteries and lightweight materials, some of them are ready to carry passengers. Up to 300 firms are working on short-range battery-powered craft that take off and land vertically. Carmakers, tech companies and others are investing money into the field. The government isoffering a glide pathto certification.America's Federal Aviation Administration is engaged in the process with around 30 firms, says Natasha Santha of LEK, a consulting company.Midway between a cab and a helicopter, flying taxis have distinct advantages over both. Quiet electric motors allow them to operate frequent services. They require only a patch of concrete to land, unlike noisy helicopters, which face severe operating restrictions in most cities. They can fly four or five times faster than a cab can drive and do not get stuck in traffic. Prices can be kept low by ride-sharing. Joby, based inCalifornia, says its five-seatermachine will enter commercial service in 2024. The firm calculates the initial cost of around $4 per person per mile may soon fall by 25%. A trip fromManhattanto JFK airport would then cost $30-40 per passenger.The real revolution will come when full autonomy takes out the cost of a pilot. Archer hopes to run such aircraft by 2028. They face fewer obstacles in the air than earth-bound cars do on the road; airliners mostly fly on autopilot as it is. Still, as one industry insider puts it, it is probably best to accustom passengers and regulators to airborne taxis before getting rid of the driver.4. What can we learn from Paragraph 1?A. The flying car can date back to the 1920s.B. Investors see the potential of the business of the flying car.C. The flying car never left the ground successfully in history.D. A German company has launched a new flying car into the market.5. What does "offering a glide path" in Paragraph 2 probably refer to?A. Giving the green light.B. Providing timely assistance.C. Presenting legal guidance.D. Conducting strict management.6. Which of the following is the strength of flying taxis?A. Costing as little as cabs.B. Saving passengers from the traffic jam.C. Reducing air pollution.D. Having no operating restrictions.7. What can be inferred about the flying taxis from the last paragraph?A. They will develop faster than cars.B. Passengers will quickly get used to taking them.C. The regulators will take measures to promote them.D. Autopilot flying taxis will probably replace those with pilots.CHaley Curfman, 25, of Blackwell, Oklahoma, is a teacher at Blackwell Public School and last yearshe bought a plain(朴素的) white dress, which she set up a station in her classroom for her students to decorate, encouraging them to go and draw on the dress whenever they had free time. Haley set up a station at a table with the dress and some color1 ed markers so that her students could draw on it, having first seen the idea on Pinterest.After the kids had finished the design, she then surprised them all by wearing the dress to class, sharing pictures of herself in it on Facebook in a post that has since been shared over 200, 000 times.For teachers looking to do something similar for their own students, Haley said that she bought the dress offAmazon for less than $ 20 about six months ago and pre-washed the dress before she started the project. She used markers from Walmart. But she said these things can be bought in other places. She said, “To do the project, I set up a station at a table with the dress and markers. It takes anywhere from two weeks to a month to complete as we just work on it here and there when time allows. You'd better give the students enough time so they don't have to hurry.”“Teachers have been sharing their dresses, T-shirts, etc. with me that they've been creating since the 1950s with the same idea. It is amazing, and I love the fact that you are sharing them with me! Thank you all so much for your kindness and support,” she wrote on Facebook.Asked why she came up with the idea, Haley told Scary Mommy. “We don't have art in our school, so, I always try to do little creative projects when possible.”8. What did Haley use the plain white dress to do?A. To teach her students painting.B. To prepare for her presentation.C. To ask her students to draw on it.D. To help her students with their homework.9. What do we know about the finished dress?A. It took Haley by surprise.B. It is kept by Haley at home.C. It is the product of a new idea.D. It has enjoyed popularity online.10. What should a teacher do if he or she wants to follow Haley's example?A. Buy the same dress online.B. Give the kids enough time.C. Buy the same markers in Walmart.D. Leave the finished work untouched.11. Why did Haley carry out the project?A. To teach art to her students.B. To show her idea on Pinterest.C. To share it with other teachers.D. To exciteher students' creativity.DRecently, I experienced a wonderful lesson in how little things still meana lot. My brother, mother and I live in Hawaii. Our farm is at least a dozen miles from even the most basic of services. Therefore, I take weekly trips to the shop to gel supplies. About a month ago, I finished loading up the car and was about to leave when a piece of paper on the ground caught my eye. I picked it up and read it carefully.Immediately, I was grateful that I had done that___4___It was a receipt (收据) from the State Motor Vehicle Division, recording the owner's payment of her Vehicle's Registration fees. I put myself in his or her shoes and thought: no one would throw this away. I looked over the receipt for any personal data, perhaps a license plate (车牌) or telephone number, but failed. How could I find the owner in the busy, crowded parking lot? Had it been lying there for a few minutes or a week? So I checked the date, the fees paid and the name of the owner, who must live in our town. I decided that the best and easiest step to take was to put the receipt in an envelope and send it to the owner first the next morning.By the end of the week, I received a beautiful “thank you” letter from a woman including a handwritten message and a card. In the letter, the woman explained how the wind took her receipt from a pocket in her car's passenger door. She had searched everywhere for quite some time before giving up.It felt great to know I had helped someone avoid a loss by doing something that seemed little and unimportant.12. What does the underlined sentence in paragraph 1 mean?A. He was lucky to learn the lesson.B. It was a good idea to do shopping that day.C. He was right to pick up the paper.D. It turned out the paper belonged to the writer.13. What information did the writer get from the paper?A The woman's license plate number.B. The woman's phone number.C. The woman's name.D. The woman's address.14. How did the woman lose the receipt?A. She forgot where she had put it.B. A strong wind blew it away.C. It fell onto the floor.D. She left it in the parking lot.15. What can be the best title for the text?A. A Lesson I Will Never ForgetB. Never Lose Heart or Give upC. Little Things Still Mean a LotD.

But there have been no reports of deaths, serious injuries or damage. Officials say the quake has not affected transportation of food and her supplies. “The ships are coming in on schedule, the supply lines are at this point working well,” the government told reporters Sunday.The Glenn Highway was probably the road hit hardest by the earthquake. It connects the state's largest city to other parts in the north. Traffic has been heavy and slow—moving since the quake. Drivers are being guided. Groups of workers are trying to rebuild areas where the quake left large holes in the road.People who are still nervous after the major quake have been more upset by more than 1, 700 aftershocks. “Anything that moves, you feel terrified”said David, whose home suffered structural(结构)damage, including a sunken foundation(地基). Actually, Alaska came up with strict building rules after a 9. 2 earthquake in 1964. That was the second most powerful earthquake on record.Government officials said a public health center promises that moneyfor medical treatment will continue to come. Mental healthy service(心理健康服务)is also available for people hurt by the disaster.Earthquake experts say there is a 4 percent chance of another 7. 0 earthquake or greater in the following week. "The chance is very small, but its not impossible, ” said the expert, Paul Caruso.4. What was the result of the earthquake?A. Buildings were damaged.B. Food supply was cut off.C.

In a newspaper.CYour best friend that follows you around when the sun comes out - your shadow - doesn’t serve an important function like your heart or brain, but what if you could use shadows to create electricity? When using solar panels (电池板) that are powered by light, shadows can be boring because it means electricity can’t be created. However, researchers from the National University of Singapore have engineered a way to create power from the shadows present everywhere.A team of the university created a machine that can collect energy from shadows. It is created by placing a thin coating of gold onto silicon (硅). Like in a normal solar panel, when put in light, the silicon electrons (电子) become energized and the energized electrons then jump from the silicon to the gold. The voltage (电压) of the part of the machine that is placed in the light increases to the dark part and the electrons in the machine flow from high to low voltage. They are sent through an external circuit (外电路) creating a current that can be used to power another machine. The greater the contrast between light and dark, more energy is provided by the machine.The team isworking on improving the performance of the machine, borrowing approaches from solar panels to gather light. Increasing the amount of light the machines can receive allows them to better make use of shadows, as well as developing shadow energy collecting panels that can successfully gather from indoor lighting. The team is also researching the use of other materials other than gold to drop the price of the machine, meaning they would be more cost effective and easier to apply in society.Shadows are present everywhere and perhaps one day in the future we will be able to collect energy from them by placing the shadow-effect energy machine around the world in places that have been considered unfit for solar panels to work, or indoors. “A lot of people think that shadows are useless,” Tan says, but “anything can be useful, even shadows.”8. What is Paragraph 1 mainly about?A. Your best friend always stays with you after the sunrise.B. The shadow has the same function as the heart and brain.C. Shadows can stop solar panels from creating electricity.D. Researchers have found a way to create power from shadows.9. What is the key working principle of the machine mentioned in the text?A. The silicon produces electricity when it is in the light.B. The gold produces power with the help of the silicon.C. The energized electrons flow from high to low voltage.D. An external circuit creates current using another machine.10. How does the team improve the performance of the machine?A. Using solar panels in the machine.B. Increasing the amount of light received.C. Developing light energy collecting panels.D. Bringing down the price of gold.11. Which of the following is the best place to apply the machine?A. A gym.B. A park.C. A farm.D. A playground.DPhotographer Rebecca Douglas has always been fascinated by the night sky. Her love for stars has taken theU.K.resident on “star walking” trips toIcelandand into theArctic, where she steps out onto darkened trails to capture twinkling stars and glowing planets in her images.Hiking at night isn’t uncommon. Plenty of people hike after dark to get to campsites or watch the sunrise from a mountaintop. Star walking goes a step further by blending hiking with stargazing. Rather than heading to an observatory or setting up a telescope in your backyard,star walking takes you on a brief journey to look at the stars from different viewpoints.Whether you’re in the mountainside or by the lake with stars reflecting on the water, star walking is often much more dynamic than traditional stargazing.What’s more, star walking is good for you. There are plenty of studies that show the health benefits of being in nature. Spending at least two hours a week outdoors, particularly while engaging in what involves “effortless attention”, can decrease blood pressure, heart rate, and stress levels.So how does an aspiring star walker get started? It doesn’t take much more than a sturdy pair of boots.While telescopes and binoculars obviously have their uses, people are encouraged to start with naked-eye stargazing. Using only the eyes allows one to get lost in the infinite expanse of space and lets the mind go.It is advised that one read up on the night sky before heading out. Free mobile apps, such as Star Walk 2, can help identify celestial bodies（天体）and are easy to use—simply point your phone at the sky to reveal a map. Websites like Sky & Telescope and NASA’s Space Place cover the basics, have in-depth explanations on stars, andoffer advice on equipment. Space Place posts monthly skywatching updates, so you can plan outings around events such as meteor showers.In the United States, national parks are great options for inexperienced night hikers. Many offer guided outings that explain the importance of protecting night skies. Those with a good number of walks under their belt may want to try GlacierNational Park in Montana.If national parks and other dark-sky designated areas are out of range, check local astronomy clubs and observatories for guided sessions. Sites like the International Astronomical Union are useful for finding resources by area.At the end of the day, the best advice is to take it slow and enjoy the journey.“With all of the chaos（混乱）that’s happening around us, the one constant has been the night sky,” explains Douglas, who hasbeen exploring popular places nearby, long after the crowds have gone home for the day. “Walking is quite a mindful way of looking up and being reminded that, although everything feels so different, some things are still the same.”12. According to the passage, star walking refers to ________.A. going to an observatoryB. looking at stars in mountainsC. combining hiking and stargazingD. setting up a telescope in the backyard13. One of the reasons why people go on a star walking is that _______.A. it’s easier to identify celestial bodiesB. it is good for physical and mental healthC. they can enjoy the journey without crowdsD. they can raise awareness of protecting night skies14. According to the passage, a star walking beginner is advised to _______.A. prepare a pair of strong bootsB. start by observing with telescopesC. join an astronomy club or an observatoryD. find guided outings with the help of mobile apps15. The main purpose of the passage is to ________.A. excite people’s interest in star walkingB. recommend some places for star walkingC. explain the health benefits of star walkingD. introduce the preparations for star walking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。

2020届重庆经开育才中学高三英语期中考试试卷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AUNUSUAL ATTRACTIONS ON THE WATERBangkokFloating MarketsThere are many floating markets where goods are sold from boats. While modem markets are more popular, floating markets still are huge attractions for local tourism. In Bangkok Floating Markets,Thailand, one of the most popular ones, any visitors can buy local foods and traditional hand-made souvenirs.Bregenzer Festspiele（Opera festival）The Bregenz Festival is held every year from July to August inVorarlberg,Austria. It has the world's largest stage on the water. The performances are different every year but they are usually united by one theme. The decorations（装饰）are very impressive and are worth seeing.Viva, ArtificialIslandArtificial islands are not something new. What makes this island special is that . it is floating. Viva is the largest out of three man-made islands along with Vista and Tera, all situated inSeoul,South Korea. The island weighs 2,000-tons and is technically a buoy（浮标）.The island unfortunately is not carbon-neutral（碳中和）but it has solar panels which can generate electricity to power the hall, restaurants and shopping malls. MarinaBayFloating Platform StadiumThis stadium was built as a temporary solution while Singapore National Stadium was rebuilt. Now it is usedfor different sporting events, concerts, and festivals. In particular, it was once used for the opening and closing ceremonies during the 2010 Summer Youth Olympics.1. What can visitors do at Bangkok Floating Markets?A. Performing.B.Boating.C. Shopping.D. Swimming.2. What do you know about Viva?A. It is the biggest island inSouth Korea.B. It has the equipment to harness solar energy.C. It is the largest floating stage on the water.D. It is a man-made island only for low-carbon life.3. Which attraction should you choose to watch a basketball match?A. Bangkok Floating Markets.B. Bregenzer Festspiele.C. Viva, ArtificialIsland.D.MarinaBayFloating Platform Stadium.BWhat about your emotions? How do they help you to understand what you are reading?In Jane Yolan'sOwl Moon,a girl explores with her father on a snowy night. She longs for this special night.And she's amazed when she sees an owl.Have you felt longing before? Amazement? Well, if you have, it helps you have a sense of agreement. When we can put ourselves inside a story we can understand it better. Our brain tells us,"Oh, this girl's experience is a bit like mine."And boom! We can relate to her.But this skill is not born in us.So young kids have to learn it.Pictures and images help young readers to understand and recognize feelings.Readers feel joy when seeing the smiling faces of friends.They feel fear when turning the page to find a scary monster. They are just pictures,but the feelings are real. This skill, to understand the thinking and feeling of others, is what researchers call "theory of mind".For example, think about the faces of people and animals in stories. The Big Bad Wolf's scary teeth. The 'o' shape of a surprised character's mouth. Or big, wide eyes like the girl inOwl Moon.By noticing the faces,readers can start to figure out what it feels like to be that character.And that helps to figure out how people feel and think in real life.But most young readers don't go into deep,scary woods.And some may not go to the beach or play basketball.In the bookYo!Yes?two kids meet and play ball. The kids start the story on opposite pages.But as the story goes on,they get closer until they are together.Some young readers might not play basketball, but they can read the clues on the page to figure out how the kids are feeling.And some readers might not like the game,but they can feel excited for the characters because of how the characters look and move.4. What can we learn from the second paragraph?A.Owl Moontalks about the exploration of the Moon.B. The feeling of"amazement"is a sense of agreement.C. Readers are blessed with the ability to interpret others.D. Readers with similar experience understand the story better.5. Which of the following might help readers develop"theory of mind"?A. True feelings.B. Smiling faces.C. Picture books.D. Reading skills.6. Young readers can go deeper into a story by________.A. tracking the plotB. developing new skillsC. sharing similar hobbiesD. analyzing the background7. What is the text mainly about?A. How thinking influences reading.B. How readers improve reading skills.C. How emotions help enhance reading.D. How kids figure out the clues of stories.CIn Copenhagen, an 8-year dream was realized when the first paid skiers took their runs down a one-third-mile course (路线)．They skied on what is possibly the greenestpower factory in the world．The factory is so clean and safe that designers were able to turn its buildings into a new center for social life．The waste-to-power factory itself opened in 2017 under the name Amager Bakke．Bjarke Ingels is the architect whosecompany came up with the idea eight years ago of designing a power plant building that would join mountain sports into its very nature．“It is the cleanest waste-to-energy power plant in the world．It is not only better for the environment, it is also moreenjoyable for the lives of its citizens.” Ingels says 97% of city people get their heating as a by-product of energy production．It comes from a system where the electricity, heating, and waste disposal (处理) are mixed into a single process．He dreams that it is also becoming an example that others can look to and say, “IfCopenhagencan do it why can' t we?"There are no hills in this island city, but now people can ski locally, while enjoying the best views ever seen of the harbor．Another thing missing hereis snow cover throughout the winter, so designers set up a kind of special "plastic grass" that provides the perfect friction (摩擦力) for downhill winter sports．In a country where 600, 000 skiers always had to travel to practice sking, to be able to finally ski in their backyard-and, all year round - is, as one skier said, “AMAZING．”The company hopes to see 300, 000 visitors enjoying the experience of Copen hill each year, with the ski slope costing $ 22 an hour or just $ 366 for a full season pass．Meanwhile, the city is one step closer to its final goal of becoming the world's first carbon-neutral city by 2025．We thinkit might be all “down hill” from here．8. How does the power factory produce electricity?A. By using oil．B. By using coal．C. By usingwind．D. By using waste．9. What' s Ingels' dream according to the passage?A. To make more tall buildings in different big cities．B. To help more skiers to ski in high mountains．C. There will be more green power factories in the world．D. More and more people will ski in the power factory．10. Where do the skiers ski in the power factory?A. On man-made snow．B. On man-made ice．C. On plastic grass．D. On real sand．11. The underlined part “it might be all 'downhill' from here" means that________.A. they will soon reach their final goalB. they will soon draw many visitorsC. they will produce more electricityD. they have difficulties reaching the goalDSam, I say to myself as I start across the bridge, you must stop these thoughts and start thinking about what to do now that you have lost your falcon, Frightful.Life, my friend Ban do once said, is meeting problems and solving them whether you are an amoeba or a space traveller. I have a problem. I have to provide my younger sister Alice and myself with meat. Fish, nuts, and vegetables are good and necessary, but they don't provide enough fuel for the hard physical work we do. Although we have venison now, I can't always count on getting it. So far this year, our venison has been only road kill from in front of Mrs Strawberry's farm.I decide to take the longest way home, down the flood plain of the West Branch of Delaware to Spillkill, my own name for a fast stream that cascades down the south face of the mountain range I'm on. I need time to think. Perhaps Alice and I should be like the early Eskimos. We should walk, camp and hunt, and when the seasons change, walk on to new food sources. But I love my tree and my mountaintop.Another solution would be to become farmers, like the people of the Iroquois Confederacy who once lived here. They settled in villages and planted corm and squash, bush beans and berries. We already grow groundnuts in the damp soil and squash in the poor land. But the Iroquois also hunted game. I can't do that anymore.I'm back where I started from.Slowly I climb the Spillkill. As I hop from rock to rock beneath shady basswoods and hemlocks, I hear the cry of the red-tailed hawk who nests on the mountain crest. I am reminded of Frightful and my heart aches. I can almost hear her call my name, Cree, Cree, Cree, Car-ree.Maybe I can get her back if I beg the man who is in charge of the peregrines at the university. “But it's the law,” he would say. I could write to the president of the United States and ask him to make an exception of Alice and me. That won't work. The president swore to uphold the Constitution and laws of the United States when he took office.I climb on. I must stop thinking about the impossible and solve the problem of what to do now. I must find a new way to provide for us. Frightful is going to be in good hands at the university, and she will have young.I smile at the thought of little Frightfuls and lift my reluctant feet.When I am far above the river, I take off my clothes and moccasins and bathe in a deep, clear pool until I am refreshed and thinking more clearly. Climbing up the bank, I dress and sit down. I breathe deeply of the mountain air and try to solve my problem more realistically.12. What does this excerpt main describe?A. Delicate mental activities.B. Unique story environment.C. Everchanging story events.D. Complicated character relationship.13. What is Sam's first worry?A. How to get back quicklyB.

Whether you’re going on a short walk or a long trip, there are a handful of apps that can help.MapMyHikeThis app tracks where you're hiking so you have a mapof your route at the end of the hike. It can also track other fitness information like the distance traveled, speed, pace, and even calories burned. You can save the data for your hike, so you can always access the route you look as well as track improvements to your workout. GaiaGPSYou don't always have cellphone service when hiking, but you always want to know where you are. The GaiaGPS app provides that information. Download maps of different parts of the world, and access the GaiaGPS app in the middle of even the most remote trails. The GPS function makes using the maps simple, and the app will also point to areas of interest.Backpacking ChecklistOne of the worst things is being way out on a trail only to discover you left behind something important. That's why checklists are the best. This checklist app helps you build a customized(定制的) list of things to take with you. Organize different lists based on trail lengths or requirements. Track all your essential items by weight and where you can find them.WildObsUsing WildObs, you can record your observations of plants and animals and add them to the database. You can ask the community to help you identify something and keep track of everything you've met, and most importantly, you can become a citizen scientist.

Backpacking Checklist.BIn the natural habitat, a binge-watcher is a strange sub-species of modern human beings. They are alone and are often found lying on their bed or sofa, still as a rock, looking searchingly into their laptop or at the TV. They rarely get up, only taking occasional breaks for those urgent calls of nature. Unlike so many others of their species, they don’t sleep at the end of every day. They stay up late and are often found to have red eyes.This, of course, is a little bit exaggerated, but for many of us, binge-watching a show is how we consume our entertainment. With streaming services bringing seemingly endless content to the tips of our finger, creatorstailortheir shows to our needs and tastes, while their marketing team sells it to us as the next most bingeable show. I can’t help but wonder if this way of consuming television does us any good.We’re advised to get 7 to 8 hours of sleep per day, but staying up all night to finish shows like ‘Breaking Bad’ and ‘The Fall’, which Netflix says are binged the fastest, won’t result in 8 hours of uninterrupted sleep. Netflix’s CEO Richard Hastings told analysts at a conference, “Think about it… when you watch a show from Netflix and you get addicted to it, you stay up late at night. We’re competing with sleep.” And it isn’t only the amount of sleep we get; the quality matters too! A study published in the Journal for Clinical Sleep Medicine reported that those who binged television more often were found to have poorer sleep quality. The mental arousal we get from watching TV doesn’t lend itself to peaceful sleep.Besides, binging TV can cause weight gain. For every extra hour of TV watched, there was a 2% increase in the prevalence of obesity, according to a study conducted by Harvard that linked TV watching to obesity in children and adolescents.While it is true that there’s growing evidence that binging isn’t good for us, the results aren’t all hopeless. Binging, occasionally, might have some benefits. For many people, binging is a good way to socialize. It gives people something to talk about at parties and with their friends. Fans of popular shows often hold viewing parties where people can binge-watch shows together and then discuss what they just experienced! This interaction can create a sense of community for many.For others, binging might just be relaxing. After a long day, a few hours of Friends—still one of the mostpopular shows on any streaming platform—can ease the stress of a long day. A study followed 240 people through their binging and recorded their stress hormones. They noted for some people that their stress hormone levels decreased during their binging experience.With binging, there is not a “good” or “bad” answer. Like many things, the key is moderation. Watching TV can be relaxing, but only if it doesn’t stop you from exercising, taking care of your health, and fulfilling your social responsibilities.4. What does the underlined word “tailor” in Paragraph 2 probably mean?A. Study.B. Sell.C. Adjust.D. Promote.5. What can we learn from the passage?A. The amount of sleep matters more than the quality.B. There’s no real harm in binge-watching a TV series.C. Binging may help keep stress hormone levels stable.D. Binge-watching may help increase social connections.6. What is the author’s attitude towards binge-watching?A. Supportive.B. Unconcerned.C. ObjectiveD. Doubtful.7. Which of the following would be the best title for the passage?A. Who Is to Blame for Binge-Watching?B. Is Binge-Watching Good or Bad for You?C. Is Binge-Watching Getting out of Control?D. HowDoes Binge-Watching Affect Your Life?CYou run into the grocery store to quickly pick up your item. You grab what you need and head to the front of the store. After quickly sizing up the check-out lines, you choose the one that looks fastest. You chose wrong. People getting in other lines long after you have already checked out and headed to the parking lot. Why does this seem to always happen to you?Well, as it turns out, it's just math that is working against you. A grocery store tries to have enough employees at the checkout lines to get all their customers through with minimum delay. But sometimes, like on a Sunday afternoon, they get super busy. Because most grocery stores don't have the physical space to add morecheckout lines, their system becomes overburdened. Some small interruption — a price check, a particularly talkative customer — will have downstream effects, holding up the entire line behind them.If there are three lines at the store, these delays will happen randomly at different registers (收银台). Think about the probability. The chances of your line being that fastest one are only one in three, which means you have a two-thirds chance of not being in the fastest line. So it's not just in your mind: Another line is probably moving faster thanyours.Now, mathematicians have come up with a good solution, which they call queuing theory, to this problem: Just make all customers stand in one long snaking line, called a serpentine line, and serve each person at the front with the next available register. With three registers, this method is about three times faster on average than the more traditional approach. This is what they do at most banks, Trader Joe's, and some fast-food places. With a serpentine line, a long delay at one register won't unfairly punish the people who lined up behind it. Instead, it will slow everyone down a little bit.8. What phenomenon is described in the first paragraph?A. Queuing in a line.B. A shopping experience.C. A rush in the morning.D. Cutting in a line.9. According to the article, what may cause delays in checking out?A. The lack of employees in the grocery store.B. Some unexpected delays of certain customers.C. The increasing items bought by customers.D. A worsening shopping system of the store.10. What is the solution given by mathematicians?A. Employing more workers for checking out.B. Limiting the number of queuing people.C. Making only one line available.D. Always standing in the same line.11. What's the principle behind the queuing theory?A. To pursue the maximum benefit.B. To leave success or failure to luck.C. To avoid the minimum loss.D. To spread the risk equally among everyone.DSmart speakers have proven to be handy devices in hospitals, allowing patients to control independently . And now, researchers from theUniversityofWashingtonhave developed an artificial intelligence system that enables these devices to monitor heartbeats.Using technology to remotely monitor heart rates isn't new. These days most smartwatches and fitness trackers are capable of it. The good thing here is that researchers have figured out a way to use the microphones in smart speakers to do it without requiring physical contact.In a study published inCommunications Biology, the researchers had the smart speakers send out signals that couldn't be heard which were then reflected off a person's body. They then analyzed these signals to identify small chest wall motions related to heartbeats, as well as separate those signals from surrounding noise and breathing.For this particular proof — of — concept setup, the researchers tested this smart speaker on 26 healthy participants and 24 hospitalized patients with various heart conditions, including atrial fibrillation（心房颤动）and heart failure. In both cases, the smart speaker was within 28 -30 milliseconds of an ECG（心电图）,the gold standard used in hospitals to discover arrhythmia（心律不齐）.Like smartwatches with advanced heart features, using smart speakers in this way opens up the possibility for passive, remote heart monitoring. ECGs, while highly accurate, require a visit to the doctor and several electrodes （电极）to be placed on the body. They,re not capable of continuous monitoring so you're limited to what it picks up at that exact moment in time ——one reason why heart arrhythmia can be so hard to discover.Smartwatches are capable of passive, remote, continuous monitoring, but they require you to wear the device at all times to be effective. It's not something that's comfortable for everyone, especially when it comes to sleep and for those with highly sensitive skin. Another issue is that these advanced smartwatches are expensive, while smart speakers are much cheaper.“If you have a device like this, you can monitor a patient on an extended basis and then develop corresponding care plans that satisfy the patient' s needs,“ said Dr. Arun Sridhar, co — senior author on the study. "And the beauty of using this kind of devices is that they are already in people's homes.”12. What does the author focus on in Paragraph 3?A. How the smart speaker works.B. Why the smart speaker is useful.C. The advantages of smart speakers.D. The importance of the study.13. Why is heart arrhythmia difficult to find?A. ECGs are not highly accurate.B. ECGs can't monitor continuously.C. Doctors know little about heart arrhythmia.D. An ECG test is hard to operate and expensive.14. Which statement best explains the characteristics of smartwatches?A. They are comfortable to wear.B. They are friendly to sensitive skin.C. They are effective and cheap.D. They are able to monitor remotely.15. What can we infer from the last paragraph?A. We need to invent more smart devices.B. Care plans are vital to patients with heart failure.C. Smart speakers could be contactless heart monitors.D. Different devices are needed to meet patients,demands.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。

B.A traveler's journal.C.A news report.D.A trip guide.BI’ve been putting my passport to good use lately. I use it asa coaster and to level unsteady table legs. It makes an excellent cat toy.Welcome to the pandemic (疫情) of disappointments. Canceled trips or ones never planned in case they would be canceled. Family reunions, study-abroad years, lazy beach vacations. Poof. Gone. Ruined by a tiny virus, the list of countries where our passports are not welcome is long.It is not natural for us to be this sedentary (定居的). Travel is in our genes. For most of the time our species has existed, we've lived as nomadic (游牧的) hunter-gatherers. But what if we can't move? What's a traveler to do? There are ways to answer that question. "Despair," though, is not one of them.We are an adaptive species. We can tolerate brief periods of forced sedentariness. We pass the days glancing through old travel journals and Instagram posts. We gaze at souvenirs. All this helps. For a while. Then, what hope do we have?I think hope lies in the very nature of travel. Travel involves wishful thinking. It demands a leap of faith, and of imagination, to board a plane for some faraway, land. Travel is one of the few activities we engage in not knowing the outcome and are drunk in that uncertainty. Nothing is more forgettable than the trip that goes exactly as planned.That's one reason why I have faith in travel's future. In fact, I'd argue travel is an essential activity. It's not essential the way hospitals and grocery stores are essential. Travel is essential the way books and hugs are essential. Food for the soul. Right now, we're between courses, enjoying where we've been, expecting where we'll go. Maybe it'sZanzibarand maybe it's the campground down the road that you've always wanted to visit.4. From the first paragraph we learn that the author is _______ .A. desperateB. humorousC. boredD. worried5. From the author's perspective, what's the point of travel?A. To feel hopeful.B. To make a wish.C. To take adventures.D. To broaden horizons.6. How is the passage mainly developed?A. By showing evidences.B. By providing examples.C. By making comparisons.D. By interpreting opinions.7. What does the passage mainly talk about?A. Where to go for a trip.B. Why people need to travel.C. How to fight the pandemic.D. What people should do at home.CBill Gates on how to fight future pandemicsWHEN HISTORIANS write the book on the covid-19 pandemic, what we've lived through so far will probably take up only the first third or so.The bulk of the story will be what happens next.I believe that humanity will beat this pandemic, but only when most of the population is vaccinated(接种疫苗）.Until then, life will not return to normal.As the pandemic slows in developed nations,itwill accelerate in developing ones.Their experience,however,will be worse.In poorer countries,where fewer jobs can be done remotely,distancing measures won't work as well.The virus will spread quickly,and health systems won't be able to care for the infected.Wealthy nations can help.But people in rich and poor places alike will be safe only once we have an effective medical solution for this virus,which means a vaccine.My hope is that,by the second half of 2021,facilities around the world will be manufacturing a vaccine.If that's the case,it will be a history-making achievement: the fastest humankind has ever gone from recognizing a new disease to immunizing（免疫）against it.Apart from this progress in vaccines,two other big medical breakthroughs will emerge from the pandemic.One will be in the field of diagnostics.The next time a novel virus crops up,people will probably be able to test for it at home.Researchers could have such a test ready within a few months of identifying a new disease.The third breakthrough will be in antiviral drugs.We haven't been as effective at developing drugs to fight viruses as we have those to fight bacteria.But that will Researchers will develop large diverse libraries of antivirals,which they'll be able to scan trough and quickly find effective treatments for novel viruses.All three technologies will prepare us for the next pandemic by allowing us to intervene(干预）early when the number of cases is still very low.Our progress won't be in science alone.It will also be in our ability to make sure everyone benefits from that science.In the years after 2021,I think we'll learn from the years after 1945. With the end of the Second World War, leaders built international institutions like the UN to prevent more conflicts.After covid-19, leaders will prepare institutions to prevent the next pandemic.These will be a mix of national,regional and global organizations.I expect they will participate in regular"germ games”in the same way as armed forces take part in War games.These will keep us ready for the next time a novel virus jumps from bats or birds to humans.I hope wealthy nations include poorer ones in these preparations,especially by devoting more foreign aid to building up their primary health-care systems.This pandemic has shown us that viruses don't obey border laws and that we are all connected biologically by a network of microscopic germs,whether we like it or not.The best analogy(类比）for today might be November 10th 1942.Britainhad just won its first land victory of the war,and Winston Churchill declared in a speech: “This is not the end.It is not even the beginning of the end.But it is,perhaps,the end of the beginning.”8. What are the three technologies that will prepare us for the next pandemic?①manufacturing a vaccine fast②diagnosing a virus at home③developing antiviral drugs④allowing us to intervene earlyA. ①②③B. ①②④C. ①③④D. ②③④9. As far as poorer countries areconcerned,which of the following is TRUE according to this passage?A. pandemic disease is more likely to begin in poorer countriesB. Working from home can work well in poorer countries.C. Health systems are sufficient to care for the infected in poorer countries.D. Virus will cross borders if poorer countries fail to contain it.10. Why is the Second World War mentioned in Para.8?A. The fight against the COVID-19 is similar to the Second World War.B. People are suffering just as they were in the Second World War.C. We should cooperate globally just as we did after the Second World War.D. Countries are fighting each other like in the Second World War.11. What is the tone of this passage?A. pessimisticB. optimisticC. neutralD. indifferentDThe shade of a single tree can provide welcome relief from the hot summer sun. But when that single tree is part of a small forest, it creates a considerable cooling effect. According to a study published today in the Proceedings of the National Academy of Sciences, trees play a big role in keeping our cities cool.According to the study, the right amount of tree cover can lower summer daytime temperatures by as much as 10 degrees Fahrenheit. And the effect is quite noticeable from neighborhood to neighborhood, even down to the scale of a single city block. “We knew that cities are warmer than the surrounding countryside, but we found that temperatures vary just as much within cities,” says Monica Turner, a professor in the department of Integrative Biology, Wisconsin-Madison University and a co-author of the study.With climate change making extreme heat events more common each summer, city planners are working on how to prepare. Heat waves drive up energy demands and costs and can have big human health impacts. One potentially powerful tool, the study's authors say, are organisms that have been around long before human civilizations could appreciate their leafy benefits. And those trees may be the secret to keeping the places we live livable.Essentially, says Turner, roads, sidewalks and buildings absorb heat from the sun during the day and slowly release that heat at night. Trees, on the other hand, not only shade those surfaces from the sun's rays, they also release water into the air through their leaves, a process that cools things down.To get the maximum benefit of this cooling service, the study found that tree cover must be more than 40 percent. In other words, an aerial picture of a single city block would need to be nearly half-way covered by a leafygreen network of branches and leaves.12. What can we infer from Paragraph 2?A. Temperatures in cities mainly depend on their green coverage.B. People living and working in cities must plant trees in summer.C. Cities are warmer than the countryside because they don't have trees.D. An area with more trees can be cooler than the other parts within a city.13. Which of the following problems is caused by extreme heat events?A. Severe damage of city facilities.B. Serious human health problems.C. Residents' growing demands for plants.D. Unnecessary waste of energy resources.14. Why are trees crucial to cities?A. They help shade and cool the cities.B. They make urban scenery beautiful.C. They build up city cooling systems.D. They essentially block and release heat.15. What can city planners conclude from the study?A. They should publish the study in a newspaper.B. They should educate citizens to protect forests.C. They should plant trees on roads and sidewalks.D. They should cover nearly half the city with trees.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。

2020年重庆经开育才中学高三英语期中考试试卷及参考答案

2020年重庆经开育才中学高三英语期中考试试卷及参考答案第一部分阅读（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AIt’s a tempting habit for them to look at their smartphone rather than make eye contact with someone. There is so much to look at: photographs, social media feeds, messages and emails. No wonder they are glued to their screens. But is it good for them?There have been many claims about the damage looking at screens does to our eyesight. Some people feared staring at a small bright box could make us short-sighted. This is a particular concern for children and young people, who spend a higher percentage of time using electronic devices. BBC reporter, Rory Jones, says, “There is enough evidence that no matter how long teenagers are spending looking at screens, they come across information about issues such as anorexia and self-harm that could prove damaging to their mental health.”But a new study says time in front of computers and phones might not be as bad for young people as many think. Research by the Oxford Internet Institute examined data from more than 17,000 teenagers in theUK,Irelandand theUnited States. Their study concluded that most links between life satisfaction and social media use were tiny, accounting for less than 1% of a teenager’s wellbeing. Professor Przybylski, director of research, said, “99.75% of a person’s life satisfaction has nothing to do with their use of social media.” The research found that family, friends and school life all had a greater impact on wellbeing.So, does this mean young people can spend longer looking at social media? TheOxfordresearchers are confident about its findings and that any connection between screen time and mental health is very small. Dr. Max Davie, officer for health improvement at theRoyalCollege, calls the study a “small first step”, but he says there are other issues to explore, such as screen time’s interference(干预) with other important activities like sleep, exercise and time with family or friends. Perhaps for now, the “right” amount of screen time is only a matter of personal judgement.1. What is people’s common belief concerning screen time?A. Looking at screens does harm to young people.B. Screen time provides a chance for teenagers to learn.C. Most teenagers get near-sighted due to looking at screens.D. A small amount of time online does little harm to teenagers.2. What can we learn from the new study by the Oxford Internet Institute?A. Screen time has a great influence on people’s daily activities.B. The right amount of the screen time is related to its content.C. There is a close link between social media and self-satisfaction.D. Social bonds play a more significant role in people’s wellbeing than social media.3. Where is the passage most probably taken from?A. A science fiction.B. A science magazine.C. A research paper.D. An economics book.BThermoelectric generators turn waste heat into electricity without producing greenhouse gas emissions, like a free lunch. But the high cost of these devices has prevented their widespread use. Now, researchers have found a way to make cheap thermae-lectrices that work just as well. The work could pave the way for greener car engines, and other energy-generating devices.“This looks like a very smart way to realize high performance,” says Li-Dong Zhao, a materials scientist. He notes there are still a few more steps before these materials can become high-performing. However, he says, “This will be used in the not too far future.”Thermoelectrics are semiconductor devices placed on a hot surface. That gives them a hot side and a cool side. If a device allows the hot side to warm up the cool side, the electricity stops flowing. A device’s success at preventing this, as well as its ability to conduct electrons, feeds into a score known as the figure of merit, or ZT.Researchers have produced thermoelectric materials with increasing ZTs. The record came in 2014 when Mercouri Kanatzidis came up with a tin selenide with a ZT of 3.1. Yet the material was too fragile to work with. “For practical applications, it’s a non-star-ter,” Kanatzidis says.Getting through that door will still take some time. The tin selenide the team makes is mixed with Na, creating a “p-type” material that conducts positive charges. To make working devices, researchers also need an “n-type” version to conduct negative charges.Zhao’s team is now working on making an n-type version. Once successful, researchers should have a clear path to making a new generation of super-efficient thermoelectric genera-tors. Those could be installed everywhere from automobile exhaust pipes to water heaters and industrial smelters toscavengesome of the 65% of fossil fuel energy that winds up as waste heat.4. The first paragraph wants to tell us________.A. The wide use of thermoelectric generatorsB. The devices of current thermoelectric generatorsC. The reason why researchers make cheap thermoelectricsD. The greener car engines that contribute to environmental protection5. How does Li-Dong Zhao feel about cheap thermoelectric generators?A. Indifferent.B. Optimistic.C. Critical.D. Worried.6. What do you know about the research in 2014 from paragraph 4 and 5?A. It was far from a success for practical applications.B. A tin selenide with a ZT of 3.1 can be easy to work with.C. Researchers made an “n-type” version to make working devicesD. A “p-type” material made from the tin selenide conducts negative charges7. What does the underlined word “scavenge” in the last paragraph mean?A. Recycle.B. Produce.C. Clean.D. Increase.CJoshua Nelson, 18, fromMissouri, is graduating fromSt. CharlesWestHigh Schoolthis week and will be attendingSoutheastMissouriStatein the fall. 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. The money will come from donations, of which there have been $16,000 so far — for a total of $17,435 at last count, according to the school. With the money already in the fund, there's enough to give out a scholarship each year for over a decade. The first scholarship was awarded on June 1 toDarrell Montalvo-Luna. As the first recipient, his scholarship was $2,000.“Joshua has the heart of a servant leader. He leads by example and he's genuinely excited when good things happen for other people," Curry said. "He's an encouragement — he's good at building others up and does what he can to help encourage and motivate those around.8. What did Nelson's initial donation come from?A. His scholarship.B. His savings.C. His pocket money.D. His wages.9. What does the underlined phrase "having an open hand" in paragraph 2 mean?A. Ambitious.B. Courageous.C. Generous.D. Cautious.10. How did Curry feel when hearing Nelson's idea?A. Shocked.B. Confused.C. Excited.D. Delighted.11. What can be inferred about the Joshua Nelson Leaders In Action Scholarship fund?A.

It is going very smoothly.DAs artificial intelligence(AI) systems become more advanced, we can expect them to be used more often in the world of human medicine and healthcare. AI is designed to imitate(模仿）the human brain in decision making and learning, so with the computing power to learn tasks in days or even hours, it is possible to create medical AIs that rapidly outperform doctors in certain tasks.Data plays a hugely important role in helping AI systems learn about human medicine. AI systems are trained on large data sets gathered from real-life cases. Providing detailed patient information in quantities is a crucial factor for their success.One of the most important areas for influencing global health is in the field of epidemiology(流行病学）。

2020年重庆经开育才中学高三英语期中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AA brother and a sister have been reunited (重逢) after more than 60 years, thanks to a letter in the Welwynand Hatfield Times. For years John Hannant kept a photo of his long-lost sister, hoping they would meet again.Margery, the eldest of three children, had signed up with the Royal Air Force as part of the war effort, when John was still a baby.The family lost touch and as many years passed only a single letter gave a clue to her whereabouts (下落). The clue was enough for a WHT reader to recognize Margery and put the family back in touch.John, 67, said he had been searching for a long time and a friend suggested writing to the paper.“That’s the one that made it, the letter to the paper,” he said. “It’s like a dream that comes true. The last time we ever heard from Margery was in 1953 after the terrible floods. She wrote home to know if we were all right.My sister Dorothy wrote back, but Margery had moved again and never got the letter.”Having retired from his job as a gardener at Park House, Mr Hannant decided to take action.He and his wife Doreen traveled to Margery’s home in Chelwood Avenue, Hatfield, which she shares with her husband Jack Cooke.Now 88, Margery was recovering from her heart operation, but immediately recognized her brother. John said, “It’s something I never thought that was going to happen but I always hoped it would.” AS well as finding his sister, John has also discovered he now has a nephew, a niece and six grandnieces and grandnephews.1.The headline of the news would be “________”.A.An unforgettable and moving experienceB.The Hannant family lost touch because of warC.A brother and a sister reunited after 60 yearsD.The importance of a letter to WHT2.Margery left her family because ________.A.she attended the air schoolB.she joined the Royal Air ForceC.she had to feed her familyD.a big flood hit her hometown3.Who helped the family reunite after many years?A.Margery’s husband Jack CookeB.The photographer of the photo of Margery.C.A neighbour of Mr Hannant.D.A reader of WHT.BMost animals living in crowded conditions have particularly strong immune systems, so it long puzzled researchers that honeybees do not.Part of the answer, discovered in 2015, is that queen bees vaccinate their eggs by moving parts of proteins from disease-causing pathogens to them before they are laid. 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.CFollowing the Famous Silk RoadsThe Silk Roads were a networkof ancient trade routes that extended from East Asia all the way to theMediterranean. A key section of the Silk Roads is the Chang’an-Tianshan corridor（走廊）, whichstretchesover a distance of around 5,000 kilometres through China, Kazakhstan and Kyrgyzstan, covering a total of 8,700 kilometres of trade routes. The three countries jointly pursued an application for UNESCO World Heritage (遗产) status which contained detailed research on the 33 sites along the corridor. This made history as the first successful multinational World Heritage application.The starting point of the corridor and the entire Silk Roads network isXi’an, inShanxiProvince. Further west on the Silk Roads, the geography gradually changes from wild deserts to high, snow-capped mountains to vast grasslands as the routes pass through theTianshanMountainsand emerge in the valleys ofCentral Asia. Although the Chang’an-Tianshan corridor of the Silk Roads ends here, the network continues westwards until it reaches theMediterranean.The corridor began to develop in the 2nd century. Assigned by the emperor, the ambassador Zhang Qian journeyed from Chang’an toCentral Asia, seeking to build bridges between the Han Dynasty and the Western Regions. Following Zhang’s efforts, trade routes took shape and relationships were strengthened between the major powers of the time, with the routes network reaching as far as theRoman Empire.Economic activities along the routes network were not limited to trade in silk. They contributed many other items to the marketplace of goods. The routes were busy with camels carrying loads of goods and businessmen selling everything imaginable.China’s exports included silk, porcelain, ironware and tea, while horses, jewellery, spices and grapes were all imported over vast distances from the West.In addition to trade exchange, the network served as a bridge for cultural exchange which shaped the evolution of science, art, technology and many other areas in societies along the network. Astronomy andmathematics were introduced toChinafromIndiaandArabia; important Chinese inventions such as papermaking and printing were brought to the West.All of these activities contributed to a great age of expansion as trade and cultural exchanges gave people access to new goods,knowledge and ideas. These routes connected Eastern and Western civilizations, which achieved a shared development. The addition of the Chang’an-Tianshan corridor to the UNESCO World Heritage List is a milestone in recognition of the Silk Roads as a crucial part of humanity’s common heritage.8.

Just a few years ago, it would have been unusable. But now, those who follow the technology know that it has got considerably better.Writing with your voice raises several interesting questions. How difficult is it actually? Human speech involves a lot more starting and stopping with errors and the need for repairing broken sentences than you may think. Even gifted speakers make mistakes. To turn the spoken word into reasonable writing requires lots of planning. You’ll need some kinds of notes or other organisers to make it work.Another question turning speech into writing raises is the style. How would writing make the change that people speak their writing rather than type? Chances are that it would come up with many more short sentences and more concrete language, which is good. It would probably also rely on prepared phrases a lot more often, which is not available when you are speaking quickly.To confirm this, a column was not written, but dictated (听写). It was composed from brief notes written down for structure only, and it was edited for length, with all of the original errors kept in. Here were the results. The first was that the literal accuracy was extremely high. There weren’t many cases wherethe software had heard one word incorrectly and written down another. But the other result was that the readability of this column was rather bad. Obviously, the blame is not with the technology at all, which turns out to be rather good. Speaking into writing relies on a better human brain than the one we currently possess. Writing is hard. There’s a reason it can’tbe done at the speed of speech, in real time.To clarify the matter, this time paragraph breaks were added after the whole writing. Punctuations (标点) had to be spoken aloud, and after a full stop, the first word in the new sentence was capitalized automatically. Some minor punctuation marks were added to make it clearer. To improve accuracy, people “trained” the software beforehand, reading a prewritten passage aloud. Actually it turns out to be more effective. All of these ensure the satisfactory completion of turning speech into writing.Language is the most important tool for human interaction, and voice is one beautiful part of language. With the maturity of modern technology, it has given birth to a great change in the human-computer voice interaction.4. According to the passage, which helps to turn speech into writing in terms of style?A. There is careful planning in advance.B. Errors and broken sentences are avoided.C. People type words as fast as they say them.D. The writing contains more prepared phrases.5. To achieve better results, the author mentions some changes for ______.A. processing errors in a column.B. adding minor punctuation marks.C. increasing the number of brief notes.D. integrating short paragraphs in writing.6. The author suggests that ______.A. human brains are responsible for poor dictated writing.B. writing with voice promises to improve the quality of writing.C. writing is an unnatural act that can hardly be learned and improved.D. technology has a long way to go in the human-computer voice interaction.7. What is the passage mainly about?A. Why people fully intend to turn speech into writing.B. What role voice technology plays in improving readability.C. Where the human-computer voice interaction is at an advantage.D. How voice technology enables the change from speech into writing.CResearchers say spicy tomatoes could soon be on the menu thanks to the rise of gene-editing technology.It's not the first time that experts have claimed techniques could develop fruit with unusual features: scientists have already been looking at changing the color1 of kiwi fruit and bettering the taste of strawberries.But researchers inBrazilandIrelandsay such methods could also offer practical advantages, with hot tomatoes offering a new way of harvesting the pungent chemicals found in peppers known as capsaicinoids, which make food taste “hot”.“Capsaicinoids are valuable. They are used as painkillers and there are some researches showing that they promote weight loss,” said Agustin Zsogon from a Brazilian university, a co-author of a new article arguing for the benefits of engineering hot tomatoes.Writing in the journal Trends in Plant Science, the researchers say peppers are difficult crops to grow and low productive. Worse still, it is tricky to keep the pungency of the fruits table. By contrast, tomato production is high and the plant is well-studied. “You could produce the capsaicinoids in a more cost-effective manner,” said Zsogon.Tomatoes and peppers developed from a common ancestor, but separated about 19 million years ago. “All these genes to produce capsaicinoids exist in the tomato, they are just not active,” said Zsogon. “Using gene-editing technology, it is likely to switch these genes back on in tomatoes, making the fruit more special”, he said.8. Why are the tomatoes made hot by the researchers?A. To test the gene-editing technologyB. To improve the amount of the tomatoesC. To explore ways to harvest more capsaicinoids.D. To make the tomatoes more delicious.9. For what purpose can capsaicinoids be used according to the text?A. To put on weight.B. To ease the pain.C. To improve sleep.D. To better the look.10. What is Zsogon's attitude to the gene-editing technology?A. Confident.B. Critical.C. Anxious.D. Doubtful.11. What's the main idea of the text?A. An introduction to gene-editing plants.B. Creating hot tomatoes by gene-editing.C. Problems with capsaicinoid production.D. The procedure of producing capsaicinoids.DTo stay healthy and fit, Chinesestudents do group exercises every day at school. Most of you probably do thesame set of exercises. But some school exercises have grown popular online due to their local and innovative designs.Singing in Sichuan dialects with energetic movements and unique mask-changing is not just a Sichuan Opera performance. It’s the routine exercise for students of Mianyang Foreign Languages Experimental School in Sichuan province.“Sichuan Opera is a local opera, and it is now facing a gap in inheritance (传承). Therefore, we cooperated with Mianyang Intangible Cultural Heritage Center to create a simple and easy-to-learn Sichuan Opera exercise,” said Shen Junhua, who is in charge of organizing the school’s exercise between classes.According to Shen, this new type of exercise has been practiced since 2017 and has been popular among students. When students enroll (入学), they will spend several weeks practicing it. At present, almost all of the students and teachers have mastered it.“In fact, we had hardly heard of Sichuan Opera before teachers taught us how to do the Sichuan Opera exercise,” said Li Yangwenwen, 14, an eighth grade student who also joined the school’s Sichuan Opera club out of interest. “It’s very different from normal exercises. After practicing it, we found it very beautiful and became interested in it. Now, almost all of the students look forward to our daily exercise time and feel excited to do it.”“By combining opera with daily exercise, the daily class activity allows students to perceive and understand Sichuan Opera’s culture”, Shen said. “After years of continuous effort to spread the seeds of traditional culture, the younger generation is finally catching on.”12. What do students in Shen’s school do during the group exercise?A. They do normal exercise .B. They sing pop songs in Sichuan dialects.C. They do mask-changing in a Sichuan Opera performance.D. They combine group exercise with Sichuan Opera.13. Why do they adopt the new type of exercise?A. To attract new students to the school.B. To inherit local culture.C. To create an easy-to-learn exercise.D. To make the school’s group exercise popular.14. How do teachers and students react to the group exercise?A. Calm.B. Indifferent.C. Enthusiastic.D. Uninterested.15. What can we learn from the last paragraph?A. Shen’s continuous effort is highly praised.B. The younger generation will have a stronger body.C. The students can better understand their local culture.D. Students help to spread the seeds of traditional culture toyounger generation.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。
