They are both famous for natural scenery.B. The best visiting time are both at nights.C. They are both located inCanadaentirely.D. The tickets there are both free at weekends.BThe prevalence of melanoma (黑素瘤) has been rapidly rising around the world for nearly a century. While some of the increase may be due to better detection, researchers also believe it’s because we’re spending more time outdoors in the sun, vacationing to warmer climates during the winter and using tanning beds. That rise is concerning, since melanoma is the most dangerous kind of skin cancer.Most of us know to cover up and apply sunscreen on hot, sunny days, but when fall arrives, we tend to drop those habits. Experts warn that’s a mistake. Though there’s less need for sun protection after summer ends, exposure to UV rays still adds up.What precautions you should take to defend against melanoma during the cooler months depends on where you are in the world. That’s because the further away you are from the equator, the more UV rays weaken in the winter. “In southern England or Canada, the daily dose of UVA on a clear summer day is 6.5 times higher than on a clear winter day,” says Professor Brian Diffey of the British Association of Dermatologists. “People in those countries typically receive only about 5% of their annual UV exposure in the winter months.”But no matter where you are, even during colder, lower risk months, it’s a mistake to put your sun-protection habits on ice. “It’s important to wear sun-screen when there is a lot of glare from the snow,” says Victoria Mar, director of the Victorian Melanoma Service at Alfred Hospital in Melbourne, Australia.Finally, you should monitor your moles(痣). “Early detection of melanoma is vital for successful treatment,” says Diffey. If it’s caught before it spreads to other parts of the body, the patient will have 99 % of chance to survive for five years. If it’s caught late, that can drop to 25%. Warning signs are a mole that’s changing size, shape or colour, or one that’s asymmetrical — sometimes referred to as “ugly duckling” moles. If you have concerns, talk to your doctor.4. What’s the main cause of the rise ofmelanoma?A. The climate change.B. Better detection.C. More exposure to the sun.D. The increase ofskin cancer.5.What’s a mistake according to experts?A. Applying sunscreen in summer.B. Wearing sun-screen when there is snow.C. Using sunscreen during lower risk months.D. Dropping sun-protection habits in winter.6. What can we learn from the last paragraph?A. Prevention is better than cure.B. Health is better than wealth.C. A disease known is half cured.D. When the sun comes in, the doctor comes out.7. What is the best title of the text?A. Detect Melanoma.B. Beware Winter Rays.C. Monitor Your Moles.D. Spend Less Time Outdoors.CWater keeps us alive. When it runs out, we have a problem.About one out of four people on the planet are facing a shortage of water. Seventeen countries around the world are dealing with high-water stress. This means they are using almost all the water they have access to. Many are dry countries. Some waste much of their water. Some may currently use too much of their groundwater that they should be saving. Several big cities face acute shortages. These include Sao Paulo, Brazil; Chennai, India; and Cape Town, South Africa. A year ago, Cape Town faced nay Zero-the day when all its dams would he dry.Climate change adds to the risk of water shortages. Rainfall is less steady. The water supply becomes less reliable. The days grow hotter. More water evaporates(蒸发)from lakes and rivers even as demand for water increases. By 2030, the number of cities in the high-stress category may have risen to 45 and include almost 470 million people.All over the world, farmers compete with city residents for water. Rich urban places, such as Los Angeles, use too much water for pools and golf courses. But the worst problem is the growth of cities. Bangalore, India, for example, had a few years with little rain. It built over its many lakes or filled them with city waste. The lakes are no longer the rain water storage tanks they once were. Bangalore now imports water. A lot of the imported water, however, gets lost on the way to Bangalore.To address this issue, what can be done? First, cities can plug leaks in their water distribution system.Wastewater can be recycled. Rain can be harvested and saved for hard times. Lakes and wetlands can be cleaned up and old wells can be restored. And farmers can switch from water-intensive crops like rice to less-thirsty crops like millet(小米).Experts are looking at ways to reduce the number of people on the planet. They are looking at ways to reduce the size of cities. They are looking for ways to encourage people, factories and farmers to use less water.8. What can we know from Paragraph 2?A. A quarter of the world's population is living with water shortages.B. Nearly all countries are facing acute water shortages now.C. Underground water should he used to meet the water demand.D. Measures have been taken to deal with the water shortage in India.9. What is the main idea of the third paragraph?A. Rainfall is not as steady as before.B. Climate change may lead to water shortages.C. The water supply relies more on rainfall.D. Hotter weather changes the water demand.10. What can farmers do to deal with water shortage?A. Plug leaks in the water distribution system.B. Clean up lakes and wetlands and restore wells.C. Reduce the number of people in the cities.D. Grow less-water consumption crops instead.11. What will be discussed if the passage continues?A. How to prevent from climate change.B. How to inspire people to save water.C. How to recycle wastewater in citiesD. How to make people get access to clean water.DIdentifying the chemical makeup of pigment (色素) used in ancient documents, paintings, and watercolor1 s is criticalto restoring and conserving the precious artworks. However, despite numerous efforts, scientists had been unable to determine the source of folium, a popular blue dye used to color1 manuscripts (手稿) in Europe during the middle ages — from the 5th to the 15th century. Now, a team of researchers fromPortugalhas finally uncovered the mysterious ingredient responsible for the gorgeous blueish-purple color1 that helped bring ancient illustrations and texts to life.The research team began byporing overinstructions penned by European dye makers from the 12th, 14th, and 15th centuries. They found what they were seeking in a 15th-century text entitledThe Book on How to Make All the Color Paints for Illuminating Books. However, translating the instructions was no easy task. It was written in the now extinct Judaeo-Portuguese language, and though the source of the dye was traced back to a plant, noname was mentioned.However, by piecing together suggestions from the text, the scientists were able to determine that the dye was made from the bluish-green berries of the chrozophora tinctoria plant. After an extensive search, the team found a few varieties of the plant growing along the roadside near the town ofMonsarazin southPortugal.The detailed instructions gave the researchers critical clues — including the best time to pick the berries. “You need to squeeze the fruits, being careful not to break the seeds, and then to put them on linen (亚麻).” The scientist says the detail was important since broken seeds polluted the pigment, producing an inferior quality ink. The dyed linen, which was left to dry, was an efficient way to store and transport the pigment during ancient times. When needed, the artist would simply cut off a piece of the cloth and dip it with water to squeeze out the blue color1 .Once the key ingredient had been identified, the researchers began to determine the dye’s molecular structure. To their surprise, they found that folium was not like any other known permanent blue dyes — it was an entirely new class of color1 , one they named chrozophoridin. “Chrozophoridin was used in ancient times to make a beautiful blue dye for painting.” the team wrote in the study. “Thus, we believe that this will not be our final word on this amazing plant and its story and that further discoveries will follow soon.”12. The primary purpose of the study is to ________.A. restore and conserve ancient precious artworksB. determine the substance making up the foliumC. prove the ancient dye-making technique was organicD. identify which class of color1 folium belongs to13. The underlined phrase “poring over”in the second paragraph means ________.A. discussing publiclyB. testing repeatedlyC. passing directlyD. reading carefully14. What can be learned about the blue dye folium?A. It was essentially an inferior type of ink.B. It was the only kind made from wild berries.C. It could be carried and used easily.D. It was carefully squeezed from broken seeds.15. The article is mainly about _________.A. how the mystery ofa thousand-year-old blue dye was solvedB. why the researchers took the trouble to recreate the dyeC. what needs to be done to make an organic dye from a plantD. when and where the discovery of the dye was made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 for Chase Burton, a deaf filmmaker fromTexas, music has always been a totally different experience.“When I was a kid, I’d lie on the floor so I could feel the vibrations (震动，颤动) from my brother’s band rocking out below my body, ” the 33-year-old man said. “That was one of the first times I began building a relationship with music.”In 2016, his ability to experience music changed dramatically, thanks to California-based technology company Not Impossible Labs. It designed a vibrating suit that enables deaf people to “feel” music through their skin. Consisting of a body harness (背带), ankle and wrist belts, the suit translates audio into a range of vibrating pulses that are felt at 24 contact points.Burtonhas been trialing the suit for four years.“The sound hits different parts of your body, ” saidBurton. “Maybe it will strikeme down in my ankles first. And then I’ll start to feel the vibrations in my back. And then I’ll feel some pulsations in my wrist.”The creators want to extends the tactile (触觉) musical experience beyond the deaf community. In 2018, they gave out 150 of the suits at a rock concert inLas Vegaswhere half the audience members were deaf and half were able to hear.Since then, Not Impossible Labs has been working to improve the technology and says it’s ready to go to market soon. Eventually, the creators want the suit to become a consumer product, accessible to all. Thecompany’s talent and business development director, Jordan Richardson, said that the technology could be used in live sports broadcasts, video games and theme parks.As a writer and director who’s been working to make the movie world more accessible,Burtonhopes that the vibrating suit will be available to his film audiences in the future. He believes the suit canenhanceemotions while watching a movie – for hearing as well as deaf people. “I see the tech as a real opportunity to help people understand that music for movies doesn’t always need to be enjoyed through the ears”.4. Why would Chase Burton lie on the floor when he was a kid?A. To feel some pulsations in his wrist.B. To feel the vibrations from his brother’s band.C. To expand the tactile musical experience.D. To begin building a bond with films.5. What do we know about Not Impossible Labs from the passage?A. It was started by Chase Burton in 2016.B. Its products have been used in live sports broadcasts.C. It is a technology company based inCalifornia.D. Its administrative director is Jordan Richardson.6. Which can replace the underlined word “enhance” in the last paragraph?A. createB. expressC. coverD. strengthen7. What is the best title for the passage?A. Vibrating Suit Allows Deaf People to “Feel” MusicB. Tech Company Provides Free Suits for Deaf PeopleC. Deaf People Enjoy Rock Music with Free SuitD. Movies Need to Be Enjoyed Through the EarsCIt is a question people have been asking for ages. Is there a way to turn back the aging process?For centuries, people have been looking for a “fountain of youth”. The idea is that if you find a magical fountain, and drink from its waters, you will not age.Researchers in New York did not find an actual fountain of youth, but they may have found a way to turn back the aging process. It appears the answer may be hidden right between your eyes, in an area called the hypothalamus (下丘脑). The hypothalamus is part of your brain. It controls important activities within the body.Researchers at New York’s Albert Einstein College of Medicine found that hypothalamus neural (神经的) stem cells also influence how fast aging takes place in the body.What are stem cells(干细胞)? They are simple cells that can develop into specialized cells, like blood or skin cells. Stem cells can also repair damaged tissues and organs.Dongsheng Cai is a professor at the Albert Einstein College of Medicine. He was the lead researcher in a study on aging in mice. He and his team reported their findings in the journal Nature, Cai explained when hypothalamus function is in decline, particularly the loss of hypothalamus stem cells, and this protection against the aging development is lost. it eventually leads to aging.Using this information, the researchers began trying to activate, or energize, the hypothalamus laboratory mice. They did this by injecting the animals with stem cells, Later, the researchers examined tissues and tested for changes in behavior. They looked for changes in the strength and coordination (协调) of the animals muscles. They also studied the social behavior and cognitive ability of the mice. The researchers say the results show that the treatment slowed aging in the animals, Cai says injecting middle-aged mice with stem cells from younger mice helped the older animals live longer.But these results were just from studying mice in a laboratory. If the mice can live longer, does that mean people could have longer lives? The next step is to see if the anti-aging effects also work in.8. In Paragraph 2 a “fountain of youth” is mentioned to ________.A. introduce the main topicB. show a hidden secret.C. describe scientists researchD. recommend a way to stay young9. Aging takes place in the body when _______.A. stem cells develop into specialized cellsB. there are important activities within the bodyC. hypothalamus neural stem cells fail to protect against agingD. the hypothalamus fails to repair damaged tissues and organs10. What do we know about the researchers at Albert Einstein College of Medicine from the text?A. They did experiments to see how stem cells work.B. They studied mice to find their connection with humans.C. They have found a possible way to slow the aging progress.D. They have found no changes in mice s behavior during the experiment11. What will the researchers probably do next?A. They will help some animals live longer.B. They will announce the fountain of youth doesn’t existC. They will develop products to help people live a longer life immediatelyD. They will do research to see if what they have found in mice will apply to humans.DA 25-year-old American with a university degree can expect to livea decade longer than a peer who dropped out of high school. Although researchers have long known that the rich live longer than the poor, this education gap is less well documented. And although the average American’s expected span(预期寿命) has been smooth in recent year—and, shockingly, even fell between 2015 and 2017—that of the one-third with a bachelor’s degree has continued to lengthen.This gap in life expectancy is growing, according to new research published in the report of the National Academy of Sciences. Anne Case and Angus Deation ofPrincetonUniversityfound that the lifespans of those with and without a bachelor’s degree started to become different in the 1990s and 2000s. This gap grew even wider in the 2010s.What is the link between schooling and longevity(长寿)? Some argue that better-educated people develop healthier lifestyles: each additional year of study reduces the chances of being a smoker and of being overweight. The better-educated earn more, which in turn is associated with greaterhealth.Ms Case and Mr Deaton argue that changes in labor markets, including the rise of automation and increased demand for highly-educated workers, coupled with the rising costs of employer-provided health care, have decreased the supply of well-paid jobs for those without a degree. This may be contributing to higher rates of alcohol and drug use, suicide and other “deaths of despair”.The authors argued that the educational gap in mortality(致死率) will widenin the wake ofthe covid-19 pandemic. ForAmerica’s overall life expectancy to start climbing again, improvements will be needed across all social groups, not just among the privileged few.12. When did the lifespans of people with and without a degree vary greatly?A. In the 1990s.B. In the 2020sC. In the 2000sD. In the 2010s13. According to the article, changes in labor markets reduce jobs for those without a degree. Which change isNOT included?A. The rising spending of employer-provided health care.B. The gap in life expectancy.C. Raised request for better-educated workers.D. The development of automation.14. What does the underlined phrase “in the wake of” probably mean ?A. afterB. untilC. beforeD. while15. What is the best title for the text?A. Changes in labor market.B. Quit bad habits by Further studyC. Educated Americans live longer.D. Highly-educated people develop healthier lifestyles.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。

And thishas great consequences on our health, our job performance, our relationships and our happiness. What is needed, she ly declares, is nothing short of a sleep revolution. Only by renewing our relationship with sleep can we take back control of our lives.In her bestseller Thrive, Arianna wrote about our need to redefine success through wellbeing, wisdom, wonder, and giving. Her discussion of the importance of sleep as a gateway to this more fulfilling way of living struck such a powerful chord (弦) that she realized the mystery and transformative power of sleep called for a fuller investigation (调查).The result is a scientifically sweeping and personal exploration of sleep from all angles, from the history of sleep, to the role of dreams in our lives, to the consequences of sleep deprivation (剥夺), and the new golden age of sleep science that is showing the vital role sleep plays in our every waking moment and every aspect of our health — from weight gain, diabetes, and heart disease to cancer and Alzheimer’s.In The Sleep Revolution, Arianna shows how our cultural removal of sleep as time wasted damages our health and our decision-making and our work lives and shortens our personal lives. She explores all the latest science on what exactly is going on while we sleep and dream. She decides the dangerous sleeping pill industry, and all the ways of our addiction to technology disturb our sleep. She also offers a range of recommendations and tips from leading scientists on how we can get better and more restorative sleep.In today’s fast-paced, always-connected and sleep-deprived world, our need for a good night’s sleep is more important than ever. The Sleep Revolution both sounds the alarm on our worldwide sleep crisis and provides adetailed road map to the great sleep awakening that can help transform our lives, our communities, and our world.4. What is the first paragraph mainly about?A. The importance of sleep.B. The necessity of improving sleep.C. The way to improve our sleep.D. The effect of sleep on health.5. What can be inferred about Arianna’s attitude to success?A. She thinks good sleep is more important.B. She doesn’t think much of becoming successful.C. She thinks it wrong to sacrifice health to success.D. She is concerned about the nature of success.6. What can be said about Arianna’s investigation?A. It is really of great value.B. It is scientific and historical.C. It costs Arianna’s sleep in practice.D. It covers all necessary aspects scientifically,7. What influence does TheSleep Revolution have on society?A. It helps to slow down the pace of modern life.B. It warns people against taking sleeping pills.C. It warns the harm of inadequate sleep of people.D. It helps to stress the value of sleep to success.COnce small farmers in Masii, a remote village in Kenya, have picked their crops, all they can do is wait until a buyer trucks through. The system works fairly well for beans and corn, but mangoes-the area’s other main crop-spoil (腐烂) more quickly. If the trader is late, they rot.However, a simple coating could change that. A company, SmartTech, has created a product that doubles the shelf life of fresh produce, enabling farmers to access far-off, larger markets. More time forfresh produce on grocers’ shelves also means less food waste-a $2.6 trillion problem, according to the United Nations’ Food and Agriculture Organization (FAO).James Rogers, CEO of SmartTech, wanted to solve the problem for food much in the same way that oxide barriers preventing rust (锈) have achieved for steel. Fortunately, researchers have found when plants made thejump from water to land, they developed cutin(蜡质), a barrier which is made of fatty acids that link together to form a seal around the plant, helping keep water in.The cutin was such a grand strategy that today you’ll still find it across the plant kingdom. SmartTech discovered through researches that an orange can last longer than a strawberry not so much because of the thickness of its skin, but because of the difference in the arrangement of those cutin molecules (分子)on the surface. After extensive trials, Rogers and his team developed a natural and tasteless protective coating from plant material-stems, leaves and skins. The product extends the sweet spot between ripening and rot. And best of all, the treated produce doesn’t require refrigeration.“SmartTech has huge potential to turn poor farmers in Africa into commercial farmers,” says Rogers. “That means more money in pockets, and more food in stomachs.” But whether the company can cost-effectively reach small farmers in far-off areas still remains a challenge.8. The author mentions the small farmers in Kenya to ________.A. stress their need for preserving produceB. show their challenge in harvesting cropsC. express their wish to reach larger marketsD. evaluate their loss caused by slow transport9. What can we learn about SmartTech’s product?A. It is financially supported by FAO.B. It is intended to replace refrigeration.C. It is designed to thicken produce’s skin.D. It is based on plants’own defence system.10. What will James Rogers probably focus on next?A. How to expand farms.B. How to earn more money.C. How to produce more tasty food.D. How to profit farmers in remote area.11. The main purpose of the passage is to ________.A. promote a productB. present a technologyC. advertise SmartTechD. introduce James RogersDBrain cells work to actively forget memories during a specific period of sleep. When we sleep our brains clear out the memories we’ve made while we’re awake, deciding what to keep and what to get rid of. Forgetting is an active process, explained the authors of the study published in the journal Science. But less is known about this process during the different periods of sleep.They found that during the rapid eye movement (REM ) sleep period — or active sleep when we are thought to dream — special nerve cells appear to actively contribute to forgetting. What are known as melanin-concentrating hormone-producing (MCH) neurons (神经元) sit in the hypothalamus (下丘脑): a part of the brain which helps with a range of functions such as sleep, appetite and emotions. Past research has suggested these cells help to control REM sleep patterns: activating the MCH neurons increasing time spentin this period, while preventingthemreducing changes into this period.The scientists looked at MCH cells in mice, and found 52.8 percent were active during REM sleep, compared with 35 percent when the mice were awake. Study co-author Thomas Kilduff, director of the Center for Neuroscience at SRI International, told Newsweek the team was surprised to find that mice performed better on learning and memory tasks when the MCH cells were prevented. “This result suggests that activation of the MCH neurons may affect memory — that is, MCH neurons may facilitate forgetting,” Kilduff explained.When asked what motivated the study, Kilduff said, “We hope the work could deepen our understanding of Alzheimer’s disease. Understanding the neural basis of learning and memory is a huge area of neuroscience research because of its effects on our everyday lives, as well as diseases such as Alzheimer’s disease. Prior to this work, no one suspected that MCH neurons had anything to do with forgetting,” said Kilduff.12. What can we infer from paragraph 1?A. Forgetting is a passive process.B. The forgetting process is known to us.C. Some memories are forgotten while we are awake.D. Certain memories are removed while we are asleep.13. What does the underlined word “them” in paragraph 2 refer to?A. REM sleep patterns.B. Past researches.C. MCH neurons.D. A range of functions.14. Why did Kilduff’s team conduct the research?A. To publish the study in the journal Science.B. To know more about Alzheimer’s disease.C. To contribute to human’s forgetting.D. To explore our everyday lives.15. What can we know about MCH?A. MCH cells takes control of REM sleep patterns .B. MCH neurons may disturb memory consolidation.C. MCH neurons have nothing to do with forgetting.D. MCH cells help mice performing better on learning.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。

ASHORTLIST OF LONDON'S BESTIf you have limited visiting time we recommend you follow this list.1)Houses of Parliament. The guided tours of the Houses of Parliament are excellent, in any language you want, and get you to places that even normal Brits can't. However, when Parliament is sitting, they are not running, but you can still get in.2)Hampton Court. We rate this as one of the best attractions in Europe. A whole succession of kings and queens have added to Henry VIII’s original palace. There lie a fantastic park (by Capability Brown) and gardens (including the famous maze), and Tudor kitchens and one of the last remaining Real Tennis courts. Lots of free (once you've paid the admission) guided tours, some in costume, by people who know and love the place. It's also surrounded by a series of parks and makes a great destination for a bike trip — train out (30 minutes from Waterloo), bike back (12 miles) along the river. We prefer it to the Tower of London — you'll probably want to visit both, it knocks the spots off Buckingham Palace.3)The River. Walk along the South Bank from Tower Bridge to Lambeth. The best of London is spread out for you: The Tower of London & Tower Bridge, The Houses of Parliament, Lambeth Palace (residence of the Archbishop of Canterbury), Shakespeare's Globe theatre, Both Tate Galleries, St Paul's Cathedral, The South Bank Centre, The Temple, The London Eye, Westminster Abbey, Somerset House. (A 2 hour walk if you don't stop forlong). Or you can take a boat out to Greenwich, the Thames Barrier or the Dome.4)Westminster Abbey. Where they crown Kings. An unreasonable admission charge (should really be free or voluntary donation), but a masterpiece anyway. If you get bored of waiting in the queue, or packed down by the crowds, hurry yourself off to the City where there's more square space of historic church, and empty.5)The Theatre. It'd be a crime to visit London and not take in a show. Londoners have been passionate about theatre for centuries. Not only is the quality high, but the price is low —one third the price of Broadway.21．Which tour will a foreign student studying the history of British Royal Family most probably prefer？A．the tour to Westminster Abbey B．the tour to Tower BridgeC．the tour to Somerset House D．the tour to Hampton Court 22．What time does the underlined statement “when Parliament is sitting” in paragraph 2 refer to?A．when the Parliament is not officially in session.B．when the members of Parliament are debating over a hot issue.C．when the Parliament is staying idle for repairs.D．when the members of Parliament are taking a break after some exercise23．Why are Londoners fond of theatre?A．They enjoy the criminal drama plots.B．They enjoy the inexpensive admission.C．They enjoy the Classical Music and Opera.D．They enjoy the scene of Shakespeare’s Globe theatre.BMy violin is like a soul mate that whispers words of wisdom to me. Together, we’ve gone through both tears and happiness.About 12 years ago, I made acquaintance with it following an order from my mom. Many hours of boredom were spent practicing it. And to make things worse, the disappointment in my teacher’s eyes as I played the wrong notes was like an invisible hammer, striking on my heart. One day, I finally decided: I hate it!By chance, things changed when I was seven. I was at home lying on the sofa, wondering how those famous violinists dealt with this terrible dilemma. I searched online for the E-minor Concerto, a well-known violin work by German composer Felix Mendelssohn, and listened to it.A beautiful and mysterious sound came from the violin as the bow moved across it. It was like the music slid over the flowers, rose up, and started to fill the air. The violin’s voice woke up the sun, made the trees green, and freshened the air. As the music changed, the sky turned back to gray. A gloomy shade covered the grass as all the sunshine disappeared. I could hear children crying and men shouting. It was like an invisible claw had grabbed my heart tightly, making it unable to beat.That glorious day set off my passion and interest in violin — I grabbed mine and never let it go. Before the memories faded, I stared at my instrument. Without hesitating, I picked it up, rosined(用松香擦) the bow, and began to play. Peace filled my heart.My violin has been by my side for 12 years. When I feel happy, an energetic tune makes it even better; when I’m deep in sorrow, a peaceful tune washes it away, when I’m walking on air, feeling especially pleased with my achievements, solemn( 庄严的) tunes calm me down. Gradually, it has become a part of my life.My violin, shall I compare you to a summer’s day?24.What further contributed to the author’s dislike of violin-playing?A.Orders from mum.B. Boredom of practice.C. Loss of passion for violin.D. Disappointment in the teacher’s e yes.25.What can be inferred from Paragraph 4?A.The author’s feeling was continuously influenced by the music.B.The weather actually changed because of the tune.C.The sudden change made the author’s heart unable to beat.D.The scenery outside the room was quite attractive.26.Why did the author pick up the violin again?A.The invisible hammer and claw are gone.B.The beautiful imagination changed his attitude.C.A famous tune aroused his interest and passion.D.He was crazy about Felix Mendelssohn’s works.27.Which of the following can be the best title for the text?A.Deep love for musicB. My dislike and like of violinC. An inspiring violinD. Musical soul mate—violinCBy now you’ve probably heard about the “you’re not special” speech, when English teacher David McCullough told graduating seniors at Wellesley High School: "Do not get the idea you're anything special, because you're not." Mothers and fathers present at the ceremony —and a whole lot of other parents across the internet — took issue with his ego-puncturing words. But lost in the anger and protest was something we really should be taking to heart: our young people actually have no idea whether they're particularly talented or accomplished or not. In our eagerness to elevate their self-esteem, we forgot to teach them how to realistically assess their own abilities, a crucial requirement for getting better at anything from math to music to sports. In fact, it's not just privileged high-school students: we all tend to view ourselves as above average.Such inflated (膨胀的) self-judgments have been found in study after study, and it's often exactly when we're least competent at a given task that we rate our performance most generously. In a 2006 study published in the journal Medical Education, for example, medical students who scored the lowest on an essay test were the most charitable in their self-evaluations, while high-scoring students judged themselves much more strictly. Poor students, the authors note, "lack insight" into their own inadequacy. Why should this be? Another study, led by Cornell University psychologist David Dunning, offers an enlightening explanation. People who are incompetent, he writes with co-author Justin Kruger, suffer from a "dual burden": they're not good at what they do, and their ineptness (笨拙) prevents them from recognizing how bad they are.In Dunning and Kruger's study, subjects scoring at the bottom of the heap on tests of logic, grammar and humor "extremely overestimated" their talents. Although their test scores put them in the 12th percentile, they guessed they were in the 62nd. What these individuals lacked (in addition to clear logic, proper grammar and a sense of humor) was "metacognitive skill" (元认知技巧): the capacity to monitor how well they're performing. In the absence of that capacity,the subjects arrived at an overly hopeful view of their own abilities. There's a paradox ( 悖论) here, the authors note: “The skills that develop competence in a particular domain are often the very same skills necessary to evaluate competence in that domain. " In other words, to get better at judging how well we’re doing at an activity, we have to get better at the activity itself.There are a couple of ways out of this double bind ( 两难). First, we can learn to make honest comparisons with others. Train yourself to recognize excellence, even when you yourself don't possess it, and compare what you can do against what truly excellent individualsare able to accomplish. Second, seek out feedback that is frequent, accurate and specific. Find a critic who will tell you not only how poorly you're doing, but just what it is that you're doing wrong. As Dunning and Kruger note, success indicates to us that everything went right, but failure is more ambiguous: any number of things could have gone wrong. Use this external feedback to figure out exactly where and when you screwed up.If we adopt these strategies — and most importantly, teach them to our children — they won't need parents, or a commencement(毕业典礼) speaker, to tell them that they're special. They'll already know that they are, or have a plan to get that way.28．What does the underlined phrase "took issue with" in paragraph 1 most probably mean? A．totally approved of B．disagreed withC．fully understood D．held discussion about29．What is the problem that shouldn't be overlooked in the author’s opinion?A．we don’t know whether our y oung people are talented or notB．young people can't reasonably define themselvesC．no requirement is set up for young people to get betterD．we always tend to consider ourselves to be privileged30．Which is NOT mentioned about poor students according to the passage?A．They lack the capacity to monitor how well they are performing.B．They usually give themselves high scores in self-evaluations.C．They tend to be unable to know exactly how bad they are.D．They are intelligently inadequate in tests and exams.31．What does the strategies of becoming special suggest?A．the best way to recognize excellence is to study past success and failureB．through comparison with others, one will know where and when he failsC．we need internal honesty with ourselves and external honesty from othersD．neither parents nor a commencement speaker can tell whether one is specialDWhile many of us may have been away somewhere nice last summer, few would say that we’ve “summered.” “Summer” is clearly a noun, more precisely, a verbed noun.Way back in our childhood, we all learned the difference between a noun and a verb. With such a tidy definition, it was easy to spot the difference. Not so in adulthood, where we areexpected to “foot” bills, “chair” committees, and “dialogue” with political opponents. Chances are you didn’t feel uncomfortable about the sight of those verbed nouns.“The verbing of nouns is as old as the English language,” says Patricia O’Conner, a former editor at The New York Times Book Review. Experts estimate that 20 percent of all English verbs were originally nouns. And the phenomenon seems to be snowballing. Since 1900, about 40 percent of all new verbs have come from nouns.Even though conversion ( 转化) is quite universal, plenty of grammarians object to the practice. William Strunk Jr. and E.B．White, in The Elements of Style — the Bible for the useof American English —have this to say: “Many nouns lately have been pressed into service as verbs. Not all are bad, but all are suspect.”The Chicago Manual of Style takes a similar standpoint, advising writers to use verbs with great care.“Sometimes people object to a new verb because they resist what is unfamiliar to them,” says O’Conner. That’s why we’re comfortable “hosting” a party, but we might feel upset by the thought of “medaling” in sports. So are there any rules for verbing? Benjamin Dreyer, copy chief at Random House, doesn’t offer a rule, but suggests that people think twice about “verbifying” a noun if it’s easily replaceable by an already existing popular verb. Make sure it’s descriptive but not silly-sounding, he says.In the end, however, style is subjective. Easy conversion of nouns to verbs has been part of English grammar for centuries; it is one of the processes that mak e English “English.” Not every coinage (新创的词语) passes into general use, but as for trying to end verbing altogether, forget it.32．What can we learn about the verbing of nouns?A．It hasn’t recently been opposed by many grammarians.B．It is more commonly accepted by children than adults.C．It hasn’t been a rare phenomenon in the past century.D．It is easily replaced by existing verbs in practice33．What is most leading experts’ attitude towards the practice of the verbing of n ouns? A．Cautious. B．Satisfied.C．Disappointed. D．Unconcerned.34．What does the author think of ending the verbing of nouns?A．Predictable. B．Practicable.C．Approaching. D．Impossible.35．What is the best title for the text?A．Are 40 Percent of all new verbs from nouns？B．Are Summering and Medaling Annoying?C．Are You Comfortable about a New Verb?D．Are There Any Rules for Verbing?第二节（共5 小题；每小题 2 分，满分10 分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。

2020届大连市第二十四中学高三英语二模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AThe question of whether our government should promote science and technology or the liberal arts in higher education isn’t an either / or one, although the current emphasis on preparing young Americans for STEM (science, technology, engineering, maths)-related fields can make it seem that way.The latest congressional report acknowledges the critical importance of technical training, but also insists that the study of the humanities and social sciences must remain central elements of America’s educational system at all levels. Both areas are the key to producing citizens who can participate effectively in our democratic society, become innovative leaders, and benefit from the spiritual enrichment that the reflection on the great ideas of mankind over time provides.Parents and students who have invested heavily in higher education worry about graduates’ job prospects as technological advances and changes in domestic and global markets transform professions in ways that reduce wages and cut jobs. Under these circumstances, it’s natural to look for what may appear to be the most “practical” way out of the problem; “major in a subject designed to get you a job” seems the obvious answer to some, though this ignores the fact that many disciplines in the humanities characterized as “soft” often, in fact, lead to employment and success in the long run. Indeed, according to surveys, employers have expressed a preference for students who have received a broadly-based education that has taught them to write well, think critically, research creatively, and communicate easily.Moreover, students should be prepared not just for their first job, but for their 4th and 5th jobs, as there’s little reason to doubt that people entering the workforce today will be called upon to play many different roles over the course of their careers. The ones who will do the best in this new environment will be those whose educations have prepared them to be flexible. The ability to take advantage of every available tool and insight—picked up from science, arts, and technology—to solve the problems of the future, and seize the opportunities, will be helpful to them and the nation.1. What does the latest congressional report suggest?A. STEM-related subjects help students find jobs in the information society.B. The humanities and STEM subjects should be given equal importance.C. The liberal arts in higher education help enrich students’ spiritual life.D. Higher education should be adjusted to the practical needs of society.2. What is the main concern of students when they choose a major?A. Their interest in relevant subjects.B. The academic value of the courses.C. The quality of education to receive.D. Their chances of getting a good job.3. What does the author say about the so called “soft” subjects?A. They benefit students in their future life.B. They broaden students’ range of interests.C. They just improve students’ communication skills.D. They are essential to students’ healthy growth.BIn Colombia a group, named WebConserva, is carrying out a project in the San Lucas Mountains with the help of coffee growers.The San Lucas area is one of the most unexplored places in Colombia, which is home to many thousands of species of animals and plants. Yet gold mining and coca farming have dealt a blow to its ecosystem. To limit additional development in the San Lucas area, the group helps coffee growers by linking them with processors from around the country.Colombia has more different kinds of living things than any other country except neighboring Brazil. In 2016, the Colombian government signed a peace deal with the Revolutionary Armed Forces of Colombia ending years of civil war. As a result, more land became accessible for use, with deforestation(毁林) coming along. Government information shows that in 2017, almost 220,000 hectares of forest were destroyed compared to around 124,000 hectares in 2015.To date, the project includes 10 families who farm 400 hectares of coffee plants, which costs about $77,000 dollars a year. WebConserva hopes that, in time, 200 families will be included. At that level, 20,000 hectares of untouched forest could be protected. In San Lucas, the families promise not to cut down trees to expand their crops or to hunt wild animals from the forests. In return, they receive $ 250 to $ 300 per 125 kilograms of coffee, an enviable amount there. Arcadio Barajas is among those taking part. His new coffee plantation(种植园) makes a barrier between cattle farms and forests where wild animals like the jaguar live and hunt. In this way, he doesn't have to kill wild animals to protect his cattle.Barajas said that pulling down the forest to plant coca and killing wildlife were against his will. Now he feels that growing coffee lets him be astewardof the land. "I'm taking care of the environment, the forest and theanimals," he said.4. Why does WebConserva set up the project?A. To help local farmers make money.B. To expand areas of coffee growing.C. To link processors with coffee growers.D. To conserve biodiversity in the Mountains.5. What happened after Colombia’s civil war was over?A. Colombia helped many needy families.B. Colombia lost lots of areas of forests.C. Colombia started to save damaged forests.D. Colombia became more peaceful than Brazil.6. Which is probably a function of Barajas's coffee plantation?A. A method of protecting cattle and wildlife.B. A substitute for hunting of wild animals.C. A barrier between man and wild animals.D. A shelter for cattle against human hunters.7. What does the underlined word "steward" mean in the last paragraph?A. Farmer.B. Master.C. Guardian.D. Explorer.CThe cumulative rainfall in Henan province during the four days was the highest since the province has records, the provincial meteorological service said. The rain was heaviest in the provincial capital, Zhengzhou, for a short period on Monday and Tuesday. Northern, western and central parts of Henan also experienced downpours, the service said. Zhengzhou's biggest one-hour precipitation (降水量) —201.9 mmbetween 4 and 5 pm on Tuesday—was also the highest on the Chinese mainland. The previous record was 198.5 mmin the village of Linzhuang in Zhumadian in August 1975, the National Meteorological Center said. The city's precipitation duringthe four days exceeded that of its average annual precipitation, the center said.Chen Tao, chief forecaster at the National Meteorological Center, said abundant water vapor (水蒸气) brought by Typhoon In-Fa and the province's special geographical features led to Henan's rain. “Partly affected by the typhoon, large amounts of water vapor have been transported to China's inland areas, including Henan,” hesaid.From Thursday to Monday, rain was forecast to continue in Henan. However, rainfall will gradually subside in Zhengzhou and the province's northern and central regions, though the storms will increase the risk of mountain torrents and other geological disasters. By Monday, lighter rain is forecast for parts of Henan, the provincial weather service said. However, local authorities are still urged to bevigilantand prepare to prevent or cope with flooding and other possible disasters.Predicting such weather events remains a challenge worldwide because it involves many meteorological phenomena, the center said. “The formation of this kind of extreme weather, including rainstorms and high temperatures, is complex,” Chen said. “We still lack effective solutions and methods for such forecasting”, he said. “We are now putting a lot of effort into tackling the difficulty. We believe that as the technology improves, we can better forecast the events.”8. What message does the author mainly want to convey in the first paragraph?A. heavy rain fell in Zhengzhou.B. The rain in Henan lasted four days.C. Zhumadian also suffered the similar heavy rain.D. Henan experienced the biggest rainfall of all time.9. What can be indicated from Chen Tao's words?A. It is not easy to forecast the extreme weather.B The rain of Henan is mainly caused by Typhoon In-Fa.C. The center hasn't put a lot of effort into solving the problem.D. Rainstorms and high temperatures can account for the heavy rain.10. What does the underlined word “vigilant” probably mean?A. Relaxed.B. Alert.C. Reluctant.D. Communicative.11. Where might the text be most probably taken from?A. history book.B. A novel.C. A news report.D. A science magazine.DTwo young brothers fromMalden.Massachusettswere in the spotlight Thursday after being named “heroes" by a national organization that recognizes young people doing great things. For the Bennett brothers, the goal of their work is nothing less than helping researchers find a cure for cancer. And their inspiration came from a friend.Thirteen-year-old Hany Bennett and his nine-year-old brother Heath run their business out of their familykitchen. "We're making lip balm（润唇膏），"Harry says. They got the idea two years ago when their friend, Timmy, was diagnosed（诊断）with cancer. brothers wanted to do something. We learned that cancer patients（lips and skin can get really dry because of chemotherapy（化疗），Hany says.A light bulb went off in both of their young heads,and " Bennett Brothers Balm was born. "We make lip balm, which is kind of like our main product/ says Heath. They also make and sell different body balms, all natural, all handmade, while the profits benefit cancer research. "We've raised S 15,000/ Heath says.And with the great optimism of children, they don't just want to help；they wont to win. We want to find a cure. We want to help doctors find a cure, Harry explains, The brothers are also Gelding a team for the Light the Night Walk, to fight cancer."I think it's great to raise money and help people who have cancer," says Heath. Their parents play a big role as well, but it's the boys who provide the most enthusiasm with a message we can all learn from. "If you want to do something... do it," Harry says. "I just feel very glad that we're helping. It feels very good”，adds Heath.Harn and Heath just received the S 10,000 Gloria Barron Prize for Young Heroes. Hwy intend to save some of il for college, invest some of it in their business and give the rest to charity. And their friend Timmy? "He's doing great. He's all better, Harry says.12.

2020届大连市第二十四中学高三英语三模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AGetting your kid to bed at night is seriously one of the most challenging things you'll ever have to do. Most kids are just so full of energy that they'll tire you out before they're halfway through their store of energy. An easy thing to calm down your child to get into bed is giving in and allowing some iPad screen time. However, it's really not a great idea, just like you thought.Researchers at theArizonaStateUniversityconducted a study with 547 kids between the ages of 7 to 9. Their parents tracked how much screen time the kids were allowed along with their sleep patterns. The study found that kids who did not engage in screen time before bed slept for 23 more minutes every week and also went to sleep about 34 minutes earlier than those playing with iPad. Although that might not seem like so much more time, quality of sleep is vastly important in Children's development.The CDC's (美国疾病控制中心)2018 National Youth Risk Survey outlines that good quality sleep can impact a child's life in many ways, including affecting grades and also weight gain. Students with an "A" average slept for 30 or more minutes per night than those with a "D" or"F" average.A 2018PennsylvaniaStateUniversitystudy showed that children with irregular bedtimes had a higher risk of having increased body weight. Those with consistent and age-appropriate bedtimes when they were 9 years old had a healthier BMI (体质指数)at age 15 than those with irregular bedtimes.Hard as it is, it's really important not to give in and hand over an iPad to your child who is about to go to bed. Just like it's important for adults to go to sleep without any distractions, it's even more important for kids.1. What do the findings of the researchers at theArizonaStateUniversitysuggest?A. More sleep is necessary for children's development.B. Enough sleep helps improve academic performances.C. Screen time before bed leads to later and less sleep.D. Children sleeping irregularly are easy to gain weight.2. What is the text mainly about?A. How is screen time affecting teenagers?B. What are negative effects of irregular bedtimes?C. When should you get your kid to bed at night?D. Why is screen time before bed a bad idea for kids?3. Who is the text intended for?A. Parents.B. Children.C. Teachers.D. Researchers.BIn a study published in Nature Machine Intelligence, researchers at Ohio State University show how artificial intelligence（AI）can follow clinical trials to identify drugs for repurposing, a solution that can help advance innovative treatments.Repurposing drugs is legal and not unusual. When doctors prescribe(开处方)drugs that have been approved by the Food and Drug Administration(FDA)for purposes different from what is printed on the labels, the drugs are being used “off-label” Just because a drug is FDA-approved for a specific type of disease does not prevent it from having possible benefits for other purposes.For example, Metformin, a drug that is FDA-approved for treating type 2 diabetes, is also used to treat PCOS(a disease of women), and other diseases. Trazodone, an anti-depressant with FDA-approval to treat depression, is also prescribed by doctors to help treat patients with sleep issues.The Ohio State University research team created an AI deep learning model for predicting treatment probability with patient data including the treatment, outcomes, and potential confounders(干扰因素).Confounders are related to the exposure and outcome. For example, a connection is identified between music festivals and increases in skin rashes(红疹). Music festivals do not directly cause skin rashes. In this case, one possible confounding factor between the two may be outdoor heat, as music festivals tend to run outdoors when the temperature is high, and heat is a known cause for rashes. When working with real-world data, confounders could number in the thousands. AI deep learning is well-suited to find patterns in the complexity of potentially thousands of confounders.The researcher team used confounders including population data and co-prescribed drugs. With this proof-of-concept, now clinicians have a powerful AI tool to rapidly discover new treatments by repurposing existing medications.4. What do we know about a drug used off-label?A. It is sold without a label.B. It is available at a low price.C. Its uses extend beyond the original ones.D. Its clinical trials are rejected by doctors.5. Metformin and Trazodone are similar as both of them________.A. are used off-labelB. treat rare diseasesC. result in sleep issuesD. are medical breakthroughs6. What can be inferred about “confounders”?A. They are possible treatments.B. They are environmental factors.C. They can be easily recognized in real-world data.D. They should be taken into serious consideration.7. What is the main idea of the text?A. AI examines benefits of existing drugs.B. AI identifies off-label uses for drugs.C. AI finds new drugs for common diseases.D. AI proves the power of drug research.COver the years, NASA has successfully sent several rovers (飞行器) to Mars. While the science laboratories continue to provide important information on the Red Planet, they keep the space exploration rovers staying closeto the original landing place.To get a more comprehensive (详尽的) view of Mars, the US Space Agency plans to make a small test helicopter with the Mars 2020 Rover, which will be sent off in July 2020.The football-sized “marscopter” weighs about four pounds.It can fly at about ten times the speed of helicopters on Earth. The light weight and fast speed are important for the helicopter to be able to fly in the thin Mars atmosphere, which is about just one percent of that of Earth. “To make it fly in that thin Mars atmosphere, we had to make everything ready, and make it as light as possible while being as strong and powerful as it can possibly be. “Mimi Aung, Mars helicopter project manager, said in a meeting.Upon landing on the Red Planet, the Mars 2020 Rover will find a proper location to send of the helicopter. The helicopter will start with a short climb, no higher than 10 feet, and hover (盘旋) for just 30 seconds before landing back on the Mars surface. If all goes well, five more flights of longer distances, for 90 seconds each, will beconducted over the next 30 days. The short journeys will be recorded by a small camera and sent back to the scientists on Earth.If the plan goes on well, the first helicopter to fly in another world, will open up a whole new way to explore Mars. The Mars helicopter's first flight will be a great invention. For those of us whose research is about flight, that would be a wonderful, historic moment.8. To fly in thin Mars atmosphere，we should make the helicopter_______.A. strong and heavyB. heavy and fastC. light and fastD. strong and slow9. How many times will the helicopter fly?A. Three timesB. Four timesC. Five timesD. Six times10. What can we learn from the last paragraph?A. It’s interesting to fly in another world.B. I' s important to fly in another world.C. The plan to fly the helicopter goes on well.D. The helicopters first flight is successful.11. What may be the best title for the passage?A. To send a helicopter to Mars in 2020B. To send a rover to Mars in 2020C. To live in the thin Mars atmosphereD. To send back records to scientistsDNASA has flown an aircraft on another planet for the first time. On Monday, April 19, Ingenuity, a 1. 8-kilogram drone (无人机) helicopter, took off from the surface of Mars, flew up about threemeters, then hovered for 40 seconds and took photos above with one of its two cameras. The historic moment was livestreamed on YouTube. “We can now say that human beings have flown a drone helicopter on another planet,” said MiMi Aung, the Ingenuity Mars Helicopter project manager at NASA's Jet Propulsion Laboratory, at a press conference. “We, together, flew at Mars, and we, together, now have our Wright brothers moment,” she added, referring to the first powered airplane flight on Earth in 1903.The details: The flight was a significant technical challenge, thanks to Mars' s bone-chilling temperatures (nights can drop down to -130 °F / -90 °C) and its incredibly thin atmosphere — just 1% the density of Earth' s. That meant Ingenuity had to be light, with rotor blades (螺旋桨) that were bigger and faster than would be needed to achieve liftoff on Earth (although the gravity on Mars, which is only about one-third of Earth's, workedin its favor). The flight had originally been scheduled to take place on April 11 but was delayed by software issues.Why it's significant: Beyond being a significantmilestonefor Mars exploration, the flight will also pave the way for engineers to think about new ways to explore other planets. Future drone helicopters could help astronauts by scoping out locations, exploring inaccessible areas, and capturing images. Ingenuity will also help inform the design of Dragonfly, a car-size drone that NASA is planning to send to Saturn's moon Titan in 2027.What's next: In the next few weeks, Ingenuity will conduct four more flights, each lasting up to 90 seconds. Each one is designed to further push the limits of Ingenuity's capabilities. Ingenuity is only designed to last for 30 Martian days, and is expected to stop functioning aroundMay 4. Its final resting place will be in the Jezero Crater as NASA moves on to the main focus of its mission: Getting the Perseverance rover (毅力号火星探测器) to study Mars for evidence of life.12. Why does MiMi Aung mention Wright brothers?A. To honor the historic contribution of Wright brothers.B. To make a comparison between Wright brothers and herself.C. To highlight the importance of Ingenuity's Martian exploration.D. To remind the public of the first powered airplane flight on Earth.13. What caused challenges for Ingenuity designers?A. The delay of software tests.B. The force of gravity on Mars.C. Mars's temperatures and atmosphere.D. Technical difficulty in liftoff on Earth.14. What does the underlined word “milestone” in Paragraph 3 probably mean?A. A great victory.B. A difficult task.C. A roadside stone.D. A historic event.15. Which of the following can be a suitable title for the text?A. Mars Drone Helicopter Makes Historic First FlightB. Modern Wright Brothers Moment: Mars ExplorationC. First Drone Helicopter Spots Evidence of Life on MarsD. Ingenuity: Mars Drone Flies to Take Incredible Pictures第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

They are concentrating on working together to solve real-world problems. They are self-driven and are coming up withamazing ideas on the spot. They are concerned with each other’s well-being as part of a team. Their concerns reach far beyond the classroom to others all over the globe.The school of the future will be an amazing melting pot of different peoples coming together to solve real-world problems.Will they even be called “schools” in the future?The teacher-student relationship is changing. Teachers are acting more as helpers rather than keepers of all knowledge. Students are driving their own education to the path that they feel best fits them. In the future,employers may not be as concerned with a diploma. They’ll look more at cases and examples of how students contribute to solving real-world problems. They’ll want to know how well they work in a team.What will problem-solving look like in the future?Information from the Internet is accessible everywhere and at unimaginable speeds. Kids are connected to news around the world in real time. Imagine someone could put out a request to the global community to help solve an issue in their own community!

2020-2021学年大连市第二十四中学高三英语模拟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APeople in the Middle Ages did eat with their hands. Personal utensils (餐具) were mostly unheard of, especially forks. There were spoons to help serve, but only special guests would receive a knife from the host. Everyone else would be expected to bring their own. Of course, eating with one's hands can be quite a sticky situation, so towels were provided to help diners stay at least somewhat clean as they ate.Still, dining was often a messy affair. At special occasions in the wealthiest households, women tended to dine alone, separate from the men. Women were expected to uphold a quality of grace. Eating greasy meat by hand would certainly not help! Once the men and women had finished their meals, they would come together to socialize.Dietary scholars of the Middle Ages believed that the foods in a meal needed to be served and eaten in order of heaviness. The lightest and most easily digested foods, such as fruits and cheeses, were eaten first to help the digestive (消化) system get started. Once digestion was underway, greens and light meats, such as lettuce, cabbage and chicken, could be eaten. Last came the heavier vegetables and meats, such as carrots, beans, beef, pork, and mutton. This method was considered the most healthful way to eat.The main and largest meal of the day was supper, and it was eaten at midday. Dinner was a light meal, and many of those in nobility (贵族) -the highest levels of the Middle Ages society-skipped breakfast altogether. Breakfast was considered unnecessary for those who did not perform physical work. Snacks and any other eating during the day were viewed the same way. Commoners, or the working class, were allowed to eat breakfast and small meals throughout the day.1. What did people in the Middle Ages usually do at the dinner table?A. They cleaned hands before meals.B. They used personal utensils.C. They had to use knives at dinner.D. They ate mostly with hands.2. What is the third paragraph mainly about?A. The order of eating foods.B. The weight of various foods.C. The principles of digesting foods.D. The list of healthy foods.3. Why did the nobility avoid eating breakfast?A. Breakfast was wasted for the nobility.B. Breakfast was viewed as unnecessary.C. Breakfast was considered as a light meal.D. Breakfast was saved for commoners.BMost teenagers are still trying to find their passion and purposes in life. However, not Gitanjali Rao. The 15-year-old girl has been coming up with innovative solutions to worldwide problems since she was ten. It is, therefore, not surprising that the teenager has won the honor of “America's Top Young Scientist”.In the third grade, Rao was inspired to build a device after witnessing the shocking story unfold in Flint, Michigan, where cost-cutting measures led to the use of a polluted river as the city's primary water supply and incredibly high levels of lead made their way into people's drinking water.After two months' research, Rao designed a small and portable device that used sensors to instantly detect lead in water. Called Tethys, after the Greek Goddess(女神) of freshwater, it attaches to a cellphone and informs the residents via an app if their drinking water contains lead. The design earned her the 3M Young Scientist Challenge in 2017. She is currently working with scientists and medical professionals to test Tethys' potential and hopes the device will be ready for commercial use by 2022.Later, Rao took on another social issue-drug addiction. Her app, called Epione, which won the Health Pillar Prize at the TCS Ignite Innovation Student Challenge in May 2019, is designed to catch drug addiction in young adults before it's too late.More recently, the teenager has developed an app named Kindly, which usesartificial intelligence technology to detect possible signs of cyberbullying(网上欺凌). When users type in a word or phrase, Kindly is able to pick it up if it's bullying, and then it gives the option to edit it or send it the way it is. It gives them the chance to rethink what they are saying so that they know what to do next time.All kinds of awesome, Gitanjali Rao has been selected from 5,000 equally impressive nominees(被提名人) for TIME Magazine's first-ever “Kid of the Year”.4. What gave Rao the idea of inventing the device Tethys?A. The incident of lead pollution.B. The issue with drug addiction.C. The shortage of water supplies.D. The high cost of purifying water.5. What is Rao expecting of Tethys?A. It'll remove metal from water.B. It'll make it to market soon.C. It'll win her a higher prize.D. It'll be fitted to cellphones.6. What will Kindly allow users to do?A. Receive pre-warning signals of threat.B. Input words into a computer automatically.C. Choose from secure social networking sites.D. Weigh their words before posting them online.7. Which of the following can best describe Gitanjali Rao as a young scientist?A. Ambitious and humble.B. Optimistic and adventurous.C. Talkative and outstanding.D. Creative and productive.CThink ofJapanin the spring and the image that comes to mind is likely the country’s famous cherry blossoms, also known as “Sakura” — white and pink flowers, blooming across cities and mountains.The flowers, which experience a “peak bloom” that only lasts a few days, have been loved inJapanfor more than a thousand years. Crowds celebrate with viewing parties,flockingto the most popular locations to take photos and have picnics underneath the branches.But this year, cherry blossom season has come and gone in the blink of an eye, in one of the earliest blooms on record. Scientists warn it’s a symptom of the larger climate crisis threatening ecosystems everywhere.Yasuyuki Aono, a researcher atOsakaPrefectureUniversity, has gathered records fromKyotoback to 812 AD from historical documents and diaries. In the central city ofKyoto, cherry blossoms peaked on March 26, the earliest in more than 1,200 years, Aono said. And in the capitalTokyo, cherry blossoms reached full bloom on March 22, the second-earliest date on record.The peak bloom dates shift every year, depending on numerous factors including weather and rainfall, buthave shown a general trend of moving earlier and earlier. InKyoto, the peak date stayed around mid-April for centuries, but began moving into early April during the 1800s. The date has only dipped into late March a handful of times in recorded history.“Sakura blooms are very temperature sensitive,” said Aono. “Flowering and full bloom could be earlier or later depending on the temperature alone,” he said. “The temperature was low in the 1820s, but it has risen by about 3.5 degrees Celsius to this day.”This year’s seasons in particular influenced the blossom dates, he added. The winter was very cold, but the spring came fast and unusually warm.8. What is the best title of the passage?A. Cherry blossom celebrations.B. Warning of a climate crisis.C. A strong love for cherry blossom.D. Cherry blossom season coming earlier.9. What does the underlined word “flocking” mean?A. Blocking.B. Flooding.C. Running.D. Following.10. What can we infer from paragraph 5?A. The peak blossom dates fall on a fixed date.B. The cherry blossom rarely peaks in March.C. The peak bloom dates mainly depend on weather and rainfall.D. Cherry blossom peaks around mid-April inTokyo.11. What is the author’s purpose in writing the passage?A. To inform people the date of cherry blossom.B. To show a study on cherry blossom dates.C. To present a Japanese tradition of cherry blossom celebration.D. To make people aware of the influence of climate change on cherry blossom.DAt Aizo Chuo Hospital in Japan, employees greet newcomers, guide patients to and from the surgery area, and print out maps of the hospital for confused visitors. They don’t take lunch breaks or even get paid. Why? They’re robots!Robots have long worked in factories, helping to build cars and electronic appliances. But today’s robots don’tjust do the jobs of people－they actually look and act a lot like people.Kansei, arobot from Japan, has a plastic face covering 19 movable parts. The robot can make 36 facial expressions in response to different words. Kansei shakes in fear at the word “war” and smiles when it hears the word “dinner”.Researchers in Europe are going even further with iCub, a “baby” robot. They are teaching it to speak and hold conversations.The ability to interact is crucial for robots that will one day work closely with humans says robotics professor ChrisAtkeson. “ This will require robots to understand what you say and how you are feeling and respond with appropriate emotions, ” he told WR News.Japanese scientist Minoru Asada agrees. He is building a robot called CB2 that acts like a real baby. “ Right now, it only goes, ̒Ah, ah. ̓But as we develop its learning function, it will start saying more complex sentences and moving on its own, ” Asada says. “ Next-generation robots need to be able to learn and develop by themselves.”Intelligent robot will become more important in the future, as populations age and the number of human workers declines in many countries. “ We’re going to have many more old people and not enough young people to care for them,” says robot researcher Matthew Mason. “ Technology can help the old people live at home longer, instead of going to nursing homes.”12. According to the passage, what jobs have robots already performed?A. Giving advice, answering customer questions and planning events.B. Producing factory goods, building cars and greeting customers.C. Greeting customers, producing factory goods and performing surgery.D. Building cars, driving passengers and providing directions.13. The second paragraph in this passage is mainly about?A. To explain how a robot works.B. To define what a robot is.C. To describe the functions of modern robots.D. To predict the future uses of robots.14. How does the Kansei robot react on the word “fire”?A. Use languages to warn nearby humans.B Back up its memory files.C. Activate an automatic fire alarm.D. Produce a worried look on his face.15. In Asada’s opinion, the next step for robots will be to develop_______.A. the ability to learn independentlyB. the ability to understand human commandsC. the capacity to interact with humansD. the willingness to work together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。
