2020届宜宾三中高三英语一模试题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ANew events and changes of junior golf competition calendarNew eventsNotah BegayⅢJunior Golf National ChampionshipWhat does a junior golfer aim to pursue? One thing is to be noticed, ideally by a college coach. A remarkable opportunity will be offered by the Notah BegayⅢJunior Golf National Championship to its participants: an event broadcast by Golf Channel. Players aged between eight and 18 can compete in the new event; information about where and when it will be held will be released later.Barbasol Junior ChampionshipBeginning the career in the PGA Tour is something that a junior golfer tends to dream of. The Barbasol Junior Championship, which is scheduled to take place between June 29 and July 2 at Keene Trace Golf Club inNicholasville,Kentucky, will provide such an opportunity. Boys under 19 years old will qualify for this new 54-hole event, and the winner will be awarded a spot at the PGA Tour's Barbasol Championship in July.Changed eventsThunderbird International JuniorThe dates of the AJGA's Thunderbird International Junior have to be changed since the NCAA Championships move to Grayhawk Golf Club inScottsdale,Arizona, for the next three years. Generally, the Thunderbird is played at the end of May. However, this year it is scheduled on different dates for the first time, from April 9 to 12, which means, of course, that the finish date is on Masters Sunday.Gator InvitationalJunior golf intends to prepare for the following college golf. If this is the case, then it is crucial to simulate the higher-level experience as much as possible. Because of that, the Gator Invitational, as a junior boys' event, has made a significant decision on becoming a 54-hole event by adding a round this year. The new version will be played from March 13 to 15 at The Country Club of Jackson inJackson,Mississippi.1. Which event can be watched on TV?A. Notah BegayⅢJunior Golf National Championship.B.

The required age of the players.D. The number of rounds it has.BWe asked four people who watched an online talk on technology and communication by Sherry Turkle for their opinions.Fred:The talk certainly gave me plenty of food for thought about how technology is changing our behaviour. People are constantly multitasking, whether it be emailing during meetings or texting in the checkout queue. It’s as if we can’t bear to miss out on what our online friends are up to, so we juggle the real and online world. My greatest concern is that we don’t give our brains a chance to switch off. It’sthese precious momentswhen we actually process information that helps us make important decisions.Jeremy:It was a fascinating talk and the speaker really hit the nail on the head with a couple of things. Take parental influence, for instance. How can we expect teenagers not to text while doing their homework when they witness their parents posting on social media while cooking the evening meal or waiting at a red light?Kath:So much of what the speaker said rang true. I honestly believe there’s a danger that the more connected we are, the more isolated we feel. I don’t think this is such an issue for my generation who’ve lived without technology for so long. We know how to be alone. But the under 20s are another kettle of fish. They’re so busy communicating that they never experience the feeling of solitude and run the risk of not learning how to enjoy their own company.Carl:I’m not sure to what extent I agree that people are more alone, but the way we communicate has certainly evolved. The speaker makes a good point about how we’re getting used to talking with machines like Siri or robots, which are totally lack of experience of human life. But despite such limitations, we seem to be expecting morefrom technology and less from each other.4. What does the underlined phrase “these precious moments” in paragraph 2 refer to?A. When our brains are free.B. When we emailing during meeting.C. When we texting in the checkout queue.D. When we juggle the real and online world.5. What suggestion may Jeremy give to the parents?A. Accompany their children when they are doing homework.B. Prevent their children using phone while doing homework.C. Set a good example for their children on using phone properly.D. Stop posting on social media in face of their children.6. What does Kath worry about the under 20s generation?A. They communicate more with others.B. They use more technology.C. It’s difficult for them to find companies.D. They don’t know how to be alone.7. What is Carl’s attitude towards the use of technology in communication?A. Favorable.B. Intolerant.C. Doubtful.D. Indifferent.CA company called Neuralink has shared a video which appears to show a monkey playing a video game, but what makes the video even stranger is that themonkey is playing the video game with just its mind.Neuralink is a company owned by Elon Musk, which is working to develop devices that could allow people to control things using just their brains. The monkey in the video is called Pager, having special "Link" devices inside his brain. These devices are connected to 2,048 wires which lead to the parts of Pager's brain that control movements of the arms and hands.Scientists taught Pager to play a video game using a banana juice as a reward when he playedthe game correctly. Soon Pager was eager to play well in order to get more smoothie. At first, Pager controlled the video game using a joystick (操纵杆). But as Pager played, his Link devices wirelessly sent out information about the signals his brain was using to control his arms and hands. Neuralink's scientists recorded all of these signals.Then they used computers to match up the signals from Pager's brain to the movements that his hands were actually doing. This was challenging work and the scientists counted on artificial intelligence (AI) to help them decode (解码) Pager's brain signals.The next step was to have a computer make moves in the video game as if Pager had actually moved the joystick. If Pager thought about moving the joystick up, the computer would send an "up"signal to the video game.Thus Pager was able to play the video game using just his brain.When people are paralyzed (瘫痪的), it's often because the brain has lost the ability to send signals to nerves and muscles in certain parts of the body. Neuralink hopes that one day, its system will be ableto send this information in a different way, allowing paralyzed people to use their arms or legs again.8. What does Neuralink aim to do?A. To make monkeys much smarter.B. To solve complex problems with monkeys.C. To create a device linking monkeys and people.D. To make people control things with their brains.9. How does the author introduce the process of the research?A. In order of time.B. By making a comparison.C. By giving examples.D. In order of space.10. What played an important role in the success of the research?A. The joystick.B. Artificial intelligence.C. The video game.D. The banana smoothie.11. Which is the most suitable title of the test?A. Neuralink Posts an Unusual VideoB. Disabled People Have a Bright FutureC. Monkey Plays Video Games with His MindD. Neuralink, a Creative and Competitive CompanyDSelf-esteem is an abstract concept, which refers to people’s beliefs about their own worth and value. American psychologist Abraham Maslow thought self-esteem was a basic human need and included self-esteem in his hierarchy of human needs. He described two different forms of “esteem”: the need for respect from others in the form of recognition, success, and admiration, and the need for self-respect in the form of self-love, self-confidence, and skill. Respect from others was believed to be more fragile and easily lost than inner self-esteem. According to Maslow, without the fulfillment of the self-esteem need, individuals will be driven to seek it and unable to grow and obtain self-realization.Basically, high self-esteem is achieved through a series of real accomplishments, which is good for people. However, the excessive high self-esteem, based more on a sense of entitlement than on any accomplishment, isconsidered to be less psychologically healthy. And just as self-esteem can be too high, it can also be “under-inflated”. Those having poor self-esteem do have a basis for feeling good about themselves but they may not recognize their accomplishments and actions as meaningful.To appreciate what it would be like to have high self-esteem, one can consider how they may feel about things in their lives that they value. For instance, some people really like cars. They take good care of their cars. They may even decorate the car and then show it off to other people with pride. Similarly, people with high self-esteem love, care for and feel proud of themselves. Take children for example. When they have high self-esteem, they believe they are valuable and important. They enjoy different activities and can handle criticism easily without taking it personally.People need to develop positive self-esteem. This can convince them they deserve happiness. Besides, the development of positive self-esteem increases the capacity to treat other people with respect, thus favoring a variety of interpersonal relationships and avoiding destructive ones.12. What can we infer from Abraham Maslow’s theory about self-esteem?A. Self-esteem ensures us a successful life.B. Self-esteem is essential to self-realization.C. Self-esteem means little to psychological health.D. Others’ respect is more important than self-respect.13. What does the underlined word “under-inflated” in paragraph 2 mean?A. Adequate.B. Insufficient.C. Moderate.D. Lifelong.14. How does the author explain the feelings of having high self-esteem?A. By giving examples.B. By analyzing causes.C. By providing figures.D. By making contrasts.15. Which of the following does the author support?A. Self-esteem ultimately leads to happiness.B. Self-esteem earns you respect from others.C. Positive self-esteem benefits people’s social lives.D. Positive self-esteem helps people out of difficulties.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 arts invite everyone to think in new ways.We often experience works of art as something that's pleasing to our senses without a full understanding of the creative effort. Great art often shows us contradictions and crises, and we can learn a great deal from their resolutions(解决). Through our understanding of art, we can gain a deeper understanding of how we might overcome our own challenges. In understanding extremes of contrast, we can see the beauty in art with themes that are not simply pleasing for their magnificent features or qualities.Beethoven offers a wonderful example of moving artfully through crises and chaos. He composed his Symphony No. 9 as his hearing loss became more and more pronounced. The opening of the symphony seems to come out of nowhere, from near silence in the opening to a full expression of what many consider to be the joy of freedom and universal brotherhood with Schiller’s Ode to joy(欢乐颂). Beethoven appears to have created a work of art that not only freed him from his personal struggles, but one that also speaks to the joy of living together in peace and harmony.Have a dialogue between the two opposing parts and you will find that they always start out fighting each other until we come to an appreciation of difference—a oneness of the two opposingforces.The arts offer many lessons that can help us gain the knowledge we need to move more confidently in today’ s competitive and uncertain environment. An openness to arts-based solutions will give you more control over your future.4. What value does art have beyond pleasing people's senses?A. It brings people inner peace.B. It contributes to problem-solving.C. It reduces the possibility of crises.D. It deepens understanding of music.5. What can we learn about Beethoven's Symphony No. 9?A. It celebrates freedom and unity.B. It aims to show crises and chaos.C. It opens with Schiller's Ode to Joy.D. It is unfinished due to his hearing loss.6. What is the author's suggestion on dealing with conflicting forces?A. Leaving things as they are.B. Making a choice between them.C. Separating them from each other.D. Engaging them in a conversation.7. Which of the following can be the best title for the text?A. How COVID-19 changes artB. Essentials of Symphony No. 9C. Moving artfully through crisesD. Joy in the eyes of BeethovenCScientists have recently discovered thatAndean condors (秀鹫)— some of the world’s largest birds——barely flap their wings at all while flying. Instead, they use rising air currents to remain in the air for hours.The Andean condor is the world’s largest soaring bird. They can weigh up to 15 kilograms. Their wings, when spread out, measure up to three meters. Their main food source is the meat of large animals which have died. Soaring high in the sky allows condors to easily spot possible meals on the ground.Scientists worked together to study the flight patterns of these huge birds and how much effort the birds use when flying. To study the birds while they were in the sky, the researchers attached special devices which could record every beat of their wings.The scientists learned that most of the condors’ flapping— over 75%— came when the birds were taking off.Once in the sky, the birds flew for very long periods of time without flapping at all. In fact, they only flapped their wings for 1% of the time they were in the air. One bird flew for over five hours without flapping, covering nearly 117miles.Soaring without flapping is important because birds bum energy every time they flap their wings.The birds’ soaring isn’t magic. They use the fact that hot air rises to keep themselves up. As hot air rises, it often creates “thermals”— currents of warm air moving upward. The condors soar by making use of these thermals. The tricky part is finding thermals and moving between them.When birds are forced to land and take off again often, it costs them a lot of energy. The researchers learned that to avoid having to land, the condors did most of their non-take-off flapping when they were closer to the ground and looking for a new thermal.The scientists reported that even though all of the condors they studied were young, they knew well how to take advantage of the air currents.8. What can we learn about the Andean condor from the text?A. They live mairly on small animals.B. Their wingspan is at least three meters.C. They rely on hot air to remain high in the sky.D. They are the birds with the strongest flying ability.9. Why was the equipment tied to the birds?A. To measure how far they could fly without flapping.B. To keep track of how often they flapped while flying.C. To calculate the energy required for their flight.D. To confirm their flight patterns.10. Which of the following acts consumes the most energy for a condor?A. Hunting for food.B. Flying in the sky.C. Getting off the ground.D. Landing on the ground.11. What can we infer from the text?A. Condors flap the most when looking for a new thermal.B. No condor can fly for more than five hours without flapping.C. Condors don’t need to look for thermals when soaring in the sky.D. Soaring by using thermals is probably a natural ability of condors.DNowadays organic food hasbecome a fashion. Organic food sales reached a record of $ 45.2 billion in 2017, making it one of the fastest-growing parts of American agriculture. Some people may buy organic food for these reasons like resource cycling and biodiversity, but most people may choose organic food because they think it's healthier. While a small number of studies have shown relationships between eating organic food and reducing risks of being ill, no studies, up to now, have answered the question whether eating organic food can improve health.According to the United States Department of Agriculture(USDA), organic food does not suggest anything about health. In 20155 Miles McEvoy, then chief of the National Organic Program for the USDA, refused to admit any health benefits of organic food, saying the question has nothing to do with the National Organic Program. Instead, the USDA thinks that organic refers to a production method that increases cycling of resources keeps ecological balance, and protects biodiversity.I'm an environmental health scientist who has spent over 20 years studying pesticides that do harm to human beings. Several years ago, I was part of the study on whether an organic diet can reduce pesticide exposure. This study focused on a group of pesticides which have always been harmful to children's brain development. We found that children who ate traditional diets had nine times higher exposure to these pesticides than children who ate organic diets.Last month, I published a small study that suggested a path forward to answering the question whether eating organic food actually improves health. My study got a lot of attention. While the results were novel, they didn't answer the big question. As I toldThe New York Timesin 2003, “What does this really mean for the safety of my kids? But we don't know. Nobody does. It was true then, and it's still true now.”12. Why do most people prefer to buy organic food?A. For its health benefits.B. For biodiversity.C. For its delicious taste.D. For resource cycling.13. What does the USDA suggest about organic food?A. It can improve people's health.B. It is produced in an environment-friendly way.C. It can reduce risks of being ill.D. It has nothing to do with the National Organic Program.14. What can be concluded from the author's study?A. Pesticides don't harm children's brain.B. Traditional diets benefit people's health.C. Organic diets can reduce pesticide exposure.D. The results are meaningful to children's safety.15. What is the best title for the text?A.What Is Organic Food?B. Is Organic Food Healthier?C. How Should We Avoid Pesticides?D. What Are the Benefits of Organic Food?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年宜宾三中高三英语期中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ABob and Sue Harvey spent nine years as resident fellows in a dormitory at Sanford and in their bookVirtual Reality and The College Freshman, they write “The Freshman oftenfaces an identity problem during the first semester.” College is a more pressured environment than it used to be, in part because the academic gap between high school and college has increased. Many college freshmen have never had to make independent decisions about sex, drugs and alcohol. Most don’t know how to manage their time or money. They often feel lonely and overwhelmed, resulting in anxiety and depression.Nancy Corbin, director of clinical service for student-counseling (咨询) services at Iowa State University, says her office is seeing a significant increase in requests for counseling from freshmen who are having trouble making the adjustment to college life. She says older teenagers increasingly lack the skills to deal with personal problems that aren’t easily defined or fixed. And they get homesick but have a hard time admitting it.Parents and high schools can make things easier on freshmen by preparing them differently. For example, by teaching them to budget their hours and dollars. The Harveys think high schools should offer a college-life course. “Parents need to focus more on relationship and personal issues and less on how many sheets and towels to take,” they say. Many homesick freshmen think they’ll be regarded as failures if they come home before Thanksgiving. So parents can help by letting them know they’re welcome to return if they feel the need. In the meantime, parents have to find new ways to keep in touch with their college kids. One of the best ways is e-mail. It’s less unpleasant and less expensive than constant phone calls and is more likely to be answered than a handwritten letter.1. Why is the first semester difficult for freshmen in college?A. Because they often fail in exams.B. Because they lack time and money.C. Because they are too homesick to make new friends.D. Because they have to settle personal issues on their own.2. In the last paragraph, it is suggested that ________.A. parents should stop buying anything for their kidsB. parents should develop a good relationship with their kidsC. parents should be taught how to send e-mails to their kidsD. parents should work with high schools in college-life courses3. Which of the following might be the best title for the passage?A. Hard Life of College FreshmenB. Approaches to Trouble in CollegeC. Freshmen’s Adaptation ProblemsD. A Strange Phenomenon in CollegeBThe founder of Earth Day was Gaylord Nelson, a U.S. Senator fromWisconsin. During the late 1960s, Americans witnessed the uninvited side effects of high productivity. Factories and power plants were sending out smoke and industrial waste while Americans were using petrol for their massive(大量的) cars, making air pollution almostsynonymous withthe nation’s development.What moved Senator Nelson to action was the 1969 massive oil spill inCalifornia, the largest in theUnited Statesat that time. The spill proved to be an environmental nightmare as it had a significant effect on marine life, killing about 3,500 sea birds, as well as marine animals such as dolphins, elephant seals and sea lions, fueling public anger. Inspired by the student antiwar movement at that period of time, Nelson found it an appropriate time to direct the energy of the students towards a fight for environmental protection. He decided that it was time to educate the Americans on the need to protect the environment. Thus Earth Day was born in 1970, and public environmentalawareness took centre stage.On 22ndApril 1970, millions of Americans took to the street and thousands of students marched to appeal for a healthy, sustainable environment. There was now a new synergy(协同作用) among different groups which had previously been fighting their causes related to the environment. Their fight for environmental conservation became so overwhelming that affected businesses were forced to follow environmental standards if they wanted to continue their operations.As it became more apparent that environmental issues were not just localized ones but a global concern, the year 1990 saw Earth Day reach out to many more around the world. Earth Day 1990 helped pave the way for the 1992 United Nations Earth Summit inRio de Janeiro, bringing together many nations for a united effort towards protecting the environment.4. Which of the following can replace the underlined phrase “synonymous with” in paragraph 1?A. familiar withB. opposite toC. different fromD. equal to5. Why did Nelson found Earth Day?A. To support students’ antiwar movement.B. To draw people’s attention to the seriousness of the oil spill.C. To arouse American’s awareness of environmental conservation.D. To educate Americans to protect marine life threatened by oil spill events.6. What can be inferred from the passage?A. Businesses would like to follow environmental standards.B. Earth Day united people to fight for environmental protection.C. It was the side effects of high productivity that led Nelson to take action.D. The 1992 United Nations Earth Summit made Earth Day known to more countries.7. The passage mainly talks about_______.A. how Earth Day came into beingB. why Earth Day was so significantC. who the founder of Earth Day wasD. what Earth Day meantto the worldCWho is a genius? This question has greatly interested humankind for centuries.Let's state clearly: Einstein was a genius. His face is almost the international symbol for genius. But we want to go beyond one man and explore the nature of genius itself. Why is it that some people are so much more intelligent or creative than the rest of us? And who are they?In the sciences and arts, those praised as geniuses were most often white men, of European origin. Perhaps this is not a surprise. It's said that history is written by the victors, and those victors set the standards for admission to the genius club. When contributions were made by geniuses outside the club—women, or people of a different color1 or belief—they were unacknowledged and rejected by others.A study recently published bySciencefound that as young as age six, girls are less likely than boys to say that members of their gender(性别)are “really, really smart.” Even worse, the study found that girls act on that belief: Around age six they start to avoid activities said to be for children who are “really, really smart.” Can our planet afford to have any great thinkers become discouraged and give up? It doesn't take a genius to know the answer: ly not.Here's the good news. In a wired world with constant global communication, we're all positioned to seeflashes of genius wherever they appear. And the more we look, the more we will see that social factors(因素)like gender, race, and class do not determine the appearance of genius. As a writer says, future geniuses come from those with “intelligence, creativity, perseverance(毅力), and simple good fortune, who are able to change the world.”8. Whatdoes the author think of victors' standards for joining the genius club?A. They're unfair.B. They're conservative.C. They're objective.D. They're strict.9. What can we infer about girls from the study inScience?A. They think themselves smart.B. They look up to great thinkers.C. They see gender differences earlier than boys.D. They are likely to be influenced by social beliefs10. Why are more geniuses known to the public?A. Improved global communication.B. Less discrimination against women.C.Acceptance of victors' concepts.D. Changes in people's social positions.11. What is the best title for the text?A. Geniuses Think AlikeB. Genius Takes Many FormsC. Genius and IntelligenceD. Genius and LuckDJapan's prime minister encouraged the decision to ban viewers, even family members, by issuing a state of emergency order in Tokyo earlier this month in response to rising COVID-19 case numbers.From the perspective of sports psychologists, an Olympics without fans is a real-life science experiment that is helping researchers and clinicians to comb through the true impact of a crowd of fans on its players—and on viewers at home. The strange circumstances under which the games are held may place unexpected pressure on some athletes. On Tuesday, superstar gymnast Simone Biles dropped out of the women's team event, telling teammates and reporters she wasn't in the right “headspace” to compete. “It's been really stressful this Olympic Games. There are a lot of different variables going into it,” Biles told the Washington Post.The 2020 Summer Olympics bears similarities and differences to other major sporting events without viewers.The English Premier League supplemented (增加) game broadcasts with crowd noise from the soccer video game FIFA 20, mixed with game audio in real time. A Taiwanese baseball team and German soccer team began populating stands with cardboard cutouts of fans, and the trend caught on internationally.Jamey Houle, the lead sports psychologist for Ohio State University Athletics and a former Al-American gymnast, says competitive athletes are trained in visualization— imagining performing a certain action or motion, such as doing a roundoff back handspring in gymnastics. Without moving a muscle, players using visualization can solidify neural (神经的) connections and activate their motor cortex (皮层). To visualize most effectively, Houle says, athletes working with sports psychologists will try to simulate as closely as possible the conditions of actual gameplay. Empty stadiums may thus have a measurable impact on players' performance. This phenomenon is grounded in a psychological concept called “social facilitation”, referring to a change in a person's performance that occurs when others are around compared to when a person is alone.12. What caused Biles to drop out of the women's team event?A. The poor physical condition.B. The absence of the audience.C. The fiercely competitive event.D. The influence of crowds of fans.13. What can be inferred from Paragraph 3?A. The Taiwanese baseball team is a success.B. The tendency mentioned is popular among some sporting events.C. The 2020 Summer Olympics is stricter in preventing the pandemic.D. The crowd noise plays a leading role in the English Premier League.14. How does Houle explain the impact of empty stadiums on players' performance?A. By doing a roundoff back handspring.B. By simulating the conditions of actual gameplay.C. By using the concept called social facilitation.D. By changing the viewers of a player.15. What message does the author mainly convey in the text?A. Athletes should be trained in visualization.B. Audience should be admitted to the Olympics.C. Social facilitation is helpful to sporting events.D. Viewers present may influence players' performance.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。

2020-2021学年宜宾三中高三英语下学期期中试题及答案解析第一部分阅读(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AIn the age of social distancing, using robots for some health care interactions is a promising way to reduce in-person contact between health care workers and sick patients. However, a key question is how patients will react to a robot entering the room. Researchers from MIT and Brigham and Women’s Hospital recently set out to answer that question.In a study, the team found that a large majority of patients reported that interacting with a health care provider through a video screen fixed on a robot was similar to an in-person interaction with a health care worker.“We’re working on robots that can help provide care to ensure the safety of the patient and the health care workforce. The results of this study give us some confidence that people are ready and willing to join us. In a larger online survey carried out nationwide, we also found that a majority of respondents were open to having robots perform small tasks such as taking a nose swab (拭子).” says Giovanni Traverso, an MIT assistant professor and the senior author of the study.After the COVID-19 pandemic began early last year, Traverso and his colleagues turned their attention toward new strategies to reduce interactions between potentially sick patients and health care workers. To that end, they created a mobile robot that could interact with patients as they waited in the emergency department. The robots were equipped with sensors that allow them to measure vital signs, including skin temperature, breathing rate, and pulse(脉搏) rate. The robots also carried an iPad for remote video communication with a health care provider.The study suggests that it could be worthwhile to develop robots that can perform tasks that currently require a lot of human effort, such as turning a patient over in bed. These days, turning COVID-19 patients onto their stomachs requires several people. Doing Covid-19 tests is another task that takes a lot of time and effort from health care workers, who could be arranged for other tasks if robots could help.1. Why did the researchers from MIT and BWH carry out the studies?A. To shorten the social distance between doctors and patients.B. To figure out the response of patients to robotic doctors.C. To reduce the risk of being infected with coronavirus.D. To ensure the safety of patients during the pandemic.2. What could be learned from the study?A. Robots are not welcomed by patients.B. Robots will soon replace doctors.C. Robots may help to deal with Covid-19 patients.D. Robots can operate on different patients.3. Which of the following is the best title for the text?A. StrengthsAnd Weaknesses In Robot CareB. The Robotic Doctor Will See You NowC. The Robots Speed Up COVID-19 TestingD. The Development Of Robots In HospitalsBThursday, two Russian submarines(潜艇) dived down 2.5 miles into the Arctic Ocean and planted a national flag onto a piece of continental shelf known as the Lomonosov Ridge. Rising from the center of the Arctic Basin, the flag sent a clear message to the surrounding nations: Russia had just laid claim(权利) to the vast oil and gas reserves contained in this underwater area.AfterRussia, theUnited States,Norway,SwedenandFinlandare all trying to gain profit. Projections show that the area of land and sea that falls within theArctic Circleis home to an estimated 90 billion barrels of oil, an incredible 13% of Earth’s reserves. It’s also estimated to contain almost a quarter of untapped global gas resources. But long before this oil race began, how did theArcticbecome so rich in energy?“The first thing you realize is that theArctic—unlike the Antarctic—is an ocean surrounded by continents”, Alastair Fraser, a geoscientist from Imperial College London, said. Firstly, this means there’s a huge quantity of organic material available, in the form of dead sea creatures such as plankton and algae, which form the basis of what will ultimately become oil and gas. Secondly, the surrounding ring of continents means that the Arctic Basin contains a high proportion of continental crust(大陆地壳), which makes up about 50% of its oceanic area. That’s significant because continental crust typically contains deep depressions called basins, into which organic matter sinks.Here, it gets inserted in rock and preserved in anoxic(缺氧) waters, meaning they contain little oxygen. “Normally, in a shallow sea with lots of oxygen, it would not be preserved. But if the sea is deep enough, the oxygenated waters at the top will be separated from the anoxic conditions at the base,” Fraser explained. Conserved within these oxygen-free basins, the matter maintains compounds that finally make it useful as anenergy source for millions of years in the future.4. Why didRussiaplant a national flag onto the Lomonosov Ridge?A. To tell surrounding countries its armed forces.B. To show its advanced technology of submarines.C. To show abundant natural resources in theArcticBasin.D. To claim its privilege to explore for oil and gas in the area.5. What’s the function of the last sentence in paragraph 2?A. Making a comparison.B. Serving as a connecting link.C. Analyzing the cause and effect.D. Drawing the conclusion of the text.6. What can we know from the last paragraph?A. Oxygen only exists in the top part of the ocean.B. Organic materials mostly exist in the basins with oxygen.C. Water containing oxygen turns organic materials into oil and gas.D. Oxygen-free environment counts in the formation of the arctic’s rich energy.7. What can be a suitable title for the text?A. What makes theArcticattractive?B. Why do many nations focus on theArctic?C. Why is there so much oil in theArctic?D. How does theArcticBasincome into being?CJohn Montefiore's path to graduation from theUniversityofTorontowas a little unusual. 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.”8. Why was Montefiore's graduation unusual?A. He had achieved personal success before.B. He understood the importance of a degree.C. He finished his degree at a much older age.D. He began his university study at a young age.9. What does the underlined word "stalled" in paragraph 2 probably mean?A. Stopped.B. Started.C. Survived.D. Succeeded.10. What can we learn about Montefiore from the third paragraph?A. He got good grades very easily.B. He took his study seriously this timeC. He was thankful for his classmates' helpD. He had difficulty using support services.11. What did Montefiore learn from his experience?A. Confidence is important in one's life.B. Others' opinions on education matter a lot.C. Higher education is a must for personal success.D. Education makes one feel better about himself.DWhen Chip heard the mail truck arriving on his sixth birthday, herushed out—not knowing that he’d come back with a treasure.Outside the house, which was decorated with birthday balloons, postwoman Shelley held a pile of boxes. One was marked with Chip’s name and a greeting for his Special day, November 5.“So,” when he came running out the door, she said, “You must be Chip!” And he said,“Yes.” She said, “Today’s your birthday?” And he started smiling. Shelley said, “So, let me see if I can find you something for your birthday.”She checked her pocket and surprised him with a gift: a dollar bill and four quarters.On this day, the 42-year-old postwoman made one little boy very happy. “He was very excited,” said his mom, Bonnie. “He came running back in the house just waving his money.” Chip is saving up to buy a Spider-man action figure.“Our family has had money problems since I lost my job. Gestures like that are valuable memories.” Her hope is that Chip and his eight-year-old sister, Bennett, will remember this when they grow up. “Not the ugly that is out there right now, but the good and the kind and the giving.”A photo of a smiling Chip and Shelley next to the mail truck has been shared widely on social media. Shelley said she was just trying to give back, because people are often nice to her eight-year-old son, Joshua.On a recent day, Chip heard the mail truck and rushed out again, this time to deliver an envelope with a thank-you card for his favorite mail carrier. Since that day, the families have kept in contact. Shelley has struggled to find someone who can take care of her son, and Bonnie has agreed to watch him at her home while his mom is on her mail route.12.

These must-see bridges are now tourist attractions in their own right.Clifton Suspension Bridge, BristolDescribed byits legendary engineer Isambard Kingdom Brunel as “my first love, my darling", it was originally designed for horse-drawn traffic. Now, more than four million vehicles a year cross the 1,352ft-long toll(通行费)bridge over the Avon Gorge. The £ 1 toll for every journey pays for its maintenance. The history of the bridge, dating back to 1864, is kept alive through a programme of tours, events and exhibitions.Infinity Bridge, Stockton-On-TeesA pedestrian(行人)and cycle footbridge across the River Tees, its working title was the North Shore Footbridge, before it was given its grander name when opened in 2009. It is particularly incredible at night. The arches(拱形)of the bridge are also lit white and, on calm nights, their reflection in the water appears as an infinity(无穷大)symbol, thus inspiring the name which was chosen by the public.Tower Bridge, LondonAn engineering wonder built from thousands of tons of Portland stone and steel, it took construction workers eight years to complete. More than 120 years old, it's a popular tourist attraction, as well as a functional bridge. Visitors can take in the views over the capital, experience seeing London life through the Glass Floor, and visit the Victorian Engine Rooms.Iron Bridge, ShropshireOpened in 1781 , this is the first arch bridge in the world made out of cast iron. Recognised as one of the great symbols of the industrial revolution, it transformed the craft of bridge building and was a crucial factor in the development of the iron trade in Shropshire.1. Which bridge has the longest history?A. Clifton Suspension Bridge.B. Infinity Bridge.C. Tower Bridge.D. Iron Bridge.2. What can we know about Infinity Bridge?A. It was originally meant for pedestrains.B. The public give it two names.C. Ifs well worth visiting at night.D. Its arch is bigger than any other bridge's.3. What makes Clifton Suspension Bridge different from the other bridges introduced?A. It charges drivers for each passing.B. It offers walkers a good view at night.C. It was made from thousands of stones.D. It's a symbol of the industrial revolution.BMy wife and I recently completed a day-long tour of the Great Wall with Jessie. In addition to being very knowledgeable about the history of theareas that we toured, she spoke excellent English and was able to answer all of our questions. Her driver was very experienced and polite, and we really enjoyed being able to have a customized tour that avoided the tourist traps and forced shopping that seem to be a part of the larger group tours.The attractions themselves were fantastic. I was a little worried that the snowy weather might impact our trip to the Great Wall, but everything went fine, and there weren’t many people out at all that day. I suggest wearing strong shoes—the Great Wall is really a hike. And in snowy or rainy days, the surfaces are pretty slippery (滑的)! Seeing this area in winter was really unique, and the snow made for great pictures. Jessie kept us entertained with stories and facts about the construction of the Wall, and always pointed out great spots for taking pictures. Even though she’s in fantastic shape, she cared about our level of fitness and often stopped to let us catch our breath.When we got back to our hotel, Jessie gave us a great recommendation for dinner and some tips for our planned stops the next day. If I find myself in Beijing in the future, I will certainly be contacting Jessie for more tour opportunities, and I’ve already recommended her to some friends who are visiting the area later in the year. I can’t say enough about how kind and knowledgeable she was, and she really gave us a great tour experience.4. What can we infer about Jessie?A. She is a tour advisor.B. She is a tour guide.C. She is a foreign traveler.D. She is a skilled driver.5. When did the writer visit the Great Wall?A. In spring.B. In summer.C. In autumn.D. In winter.6. What did the writer think of his tour?A. Adventurous.B. Disappointing.C. Satisfactory.D. Improvable.7. What is the probable title for the text?A. A Wonderful Tour Day with JessieB. An Extraordinary Tour CompanyC. The Great Wall, an Excellent AttractionD. Jessie, a Kind and Knowledgeable GuideCBrain 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.8. 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.9. 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.10. 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.11. 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.DThe Gata used to look annoyed when they received power bills that routinely topped $200. Last September the couple moved into a 1,500-square-foot home in Premier Gardens, an area of 95 “zero-energy homes” (ZEH) just outside town. Now they're actually eager to see their electricity bills. The grand total over the 10 months they've lived in the three-bedroom house: $75. For the past two months, they haven’t paid a cent.ZEH communities are the leading edge of technologies that might someday create houses that produce as much energy as they consume. Premier Gardens is one of a half-dozen subdivisions (住宅开发项目) in California where every home cuts power consumption by 50%, mostly by using low power appliances and solar panels.Aside from the panels on the roof, Premier Gardens looks like a community of traditional homes. But inside, special windows cut power bills by blocking solar heat in summer and keeping indoor warmth winter.The rest of the energy savings comes from the solar units. They don't just feed the home they serve. If they generate more power than the home is using, the excess flows into the utility's power grid(电网). The residents are billed by “net metering”: they pay for the amount of power that they get from the grid, minus the kilowatts(千瓦) they feed into it. If a home generates more power than it uses, the bill is zero.That sounds like a bad deal for the power company, but it's not. Solar homes produce the most power on the hot sunny afternoons when everyone rushes home to turn up the air conditioner. "It helps us lower usage at peak power times," says solar expert Mike Keesee. “That lets us avoid building costly plants or buying expensive power at peak usage time.”What’s not to like? Mostly the costs. The special features can add $25,000 or more to the purchase price of a house. Tax breaks bring the cost down, especially in California, but in many states ZEHs can be extremely expensive. For the consumer, it's a matter of paying now for the hardware to save later on the power bill.12. Why is the Gata eager to see their electricity bills now?A. They want to cut down their utility' expenses.B. They want to know if they are able to pay.C. They want to see how much they have saved.D. They want to avoid being overcharged.13. What is special about the ZEH communities?A. They are built in harmony with the environment.B. They have created cutting edge technologies.C. They are subdivided into half a dozen sections.D. They aim to be independent in power supply.14. What does the "net metering" practice mean to the power company?A. More pressure at peak timeB. Reduced operational costs.C.

Such research has indicated that to form long-term memories—ones that last a day or more—the insects need to repeat a training experience at least three times. By contrast, short-and mid-term memories that last seconds to minutes and minutes to hours, respectively, need only a single learning experience.Exceptions to this rule have been observed, however. For example, in some studies, bees formed long-lasting memories after a single learning event. Such results are often regarded as circumstantial anomalies, says Martin Giurfa of the University of Toulouse. But the anomalous findings, together with research showing that fruit flies and ants can form long-term memories after single experiences, aroused Giurfa’s curiosity. Was it possible that honeybees could reliably do the same? Giurfa reasoned that the ability to form long-term memories might depend on the particular type of bee and the experience. Within a honeybee colony, there are nurses, who clean the hive and feed the young; guards, who patrol and protect the hive; and foragers, who search for nectar.While previous studies have tested bees as a whole, Ciurfa and his colleagues focused on foragers, tasking them with remembering an experience relevant to their role: an odor associated with a sugary reward.The researchers observed that a single exposure to a reward-paired odor was enough for most forager bees to remember that specific odor the following day. Many foragers could even remember the odor three day later.The results do not mean that all prior research was wrong, says André Fiala of the University of Göttingen. “People have done the experiments in a different way.” Still, the new results do show that “the commonly held belief that one needs multiple training trials to achieve long-term memory is not always true,” he says, and this “really advances the field.”4. What does the author want to tell us through Paragraph 1?A. A model for memory research.B. The classification of memories.C. New research on learning and memory.D. Previous findings on memory formation.5. Which factor might influence a bee’s memory of an experience, according to Giurfa’s research?A. Whether the bee's role is related.B. Whether the bee is introduced or native.C. How often the bee repeats the experience.D. How long the bee is exposed to the reward.6. What is Andre Fiala’s attitude towards the new results?A. Doubtful.B. Favorable.C. Intolerant.D. Unclear.7. Which of the following is a suitable title for the text?A. Learning and Memory: How Honeybees RememberB. Honeybee Memory: Honeybee Knows What to DoC. Honeybees Remember after Just One LessonD. Honeybees Use Memory for CommunicationCIt is that time of year when people need to lock their cars. It’ s not because there are a lot of criminals running around stealing cars. Rather, it’ s because of the good-hearted neighbors who want to share their harvest. Especially with this year’s large crop, leaving a car unlocked in my neighborhood is an invitation for someone to stuff it full of zucchini(西葫芦).My sister-in-law, Sharon, recently had a good year for tomatoes. She and her family had eaten and canned so many that they began to feel their skin turn slightly red. That ’ s when she decided it was time to share herblessings.She started calling everyone she knew. When that failed, she began to ask everyone in the neighborhood like a politician, eventually finding a neighbor delighted to have the tomatoes. “ Feel free to take whatever you want,”Sharontold her. She felt happy that she could help someone and that the food didn’t go to waste.A few days later,Sharonanswered the door. There was the neighbor, holding some bread. The neighbor smiled pleasantly, “I want to thank you for all of the tomatoes, and I have to admit that I took a few other things and hope you wouldn’t mind.”Sharoncouldn’t think of anything else in her garden that had been worth harvesting and said so. “Oh, but you did,” the neighbor said. “You had some of the prettiest zucchini I’ve ever seen.”Sharonwas confused. Zucchini in her garden? They hadn’ t even planted any zucchini. But her neighbor insisted that there really were bright-green zucchini in her garden. The two of them walked together into the backyard. When the neighbor pointed at the long green vegetables,Sharonsmiled, “ Well, actually, those arecucumbers that we never harvested, because they got too big, soft and bitter for eating or canning.”The neighbor looked atSharon, shock written all over her face. Then she smiled, and held out the bread that she had shared all over the neighborhood, “I brought you a loaf of cucumber bread. I hope you like it.”8. Why does the author suggest that people in the neighborhood should lock their cars?A. They might be stolen by thieves.B. They might be moved away by the police.C. Their neighbors might fill them with their harvest.D. Their neighbors might throw rubbish in them.9. What does the underlined word “blessings” in the second paragraph mean?A. Tomatoes.B. God’s protection.C.Helpful things.D. Best wishes.10. What did the neighbor do inSharon’s garden?A. She harvested tomatoes only.B. She harvested zucchini by accident.C. She took some cucumbers mistakenly.D. She stole something withoutSharon’s permission.11. We can infer from the article that the neighbor’s bread would taste________.A. bitter but tastyB. strange and bitterC. hard and sourD. soft and sweetDTofight for the conservation of forest ecosystem, several ecologists including Daniel Janzen convinced Del Oro, an orange juice producer, to donate part of their forestland to a national park. In return, Del Oro was allowed to throw large amounts of waste in the form of orangepeels(皮) on a 3-hectare piece of land within the national park at no cost. Dealing with tons of leftover peels usually involved burning them or paying to have them poured into a landfill, so the proposal was very attractive.But a year later, another juice company challenged the deal in court, arguing that their competitor was "polluting a national park". They ended up winning, and the deal between Del Oro and the national park fell through.Then in 2013, while discussing possible research avenues(途径,手段)with Timothy Treuer, Daniel Janzen mentioned the orange story. Feeling interested, Treuer decided to stop by that piece of land that had beencovered with fruit waste 15 years earlier. What he found shocked him."While I would walk over exposed rock and dead grass in the nearby fields, I'd have to climb through undergrowth and cut paths through walls ofvines(藤) in the orange peel site itself," said Timothy Treuer.Treuer and his team spent months picking upsamples(样品), analyzing and comparing them. They found great differences between the areas covered with orange peels and those that were not. The area withorange waste had richer soil.The effect that the orange peels had on the land is probably not that surprising to people familiar withcomposting(施肥), but what is really shocking is that a judge actually thought the waste of orange "mined" a national parkand stopped it from going forward. Now that Timothy Treuer's study has received worldwide attention, this type of "ruining" is being seriously considered as a way of bringing forests back to life.12. What did Del Oro usually do with orange peels?A. Add them to fuel.B. Feed them to animals.C. Burn or bury them.D. Make them into cakes.13. What can we know about the deal between Del Oro and the national park?A. It lasted 15 years.B. It was signed by Treuer.C. It was made in about 1998.D. It was broken by Del Oro.14. What was Treuer's finding?A. Orange peels contain much fibre.B. Orange peels can make soil richer.C. Orange peels rot away in a short time.D. Orange waste ruined the national park.15. What is the author's attitude toward the judge mentioned in the last paragraph?A. Disapproving.B. Positive.C. Worried.D. Admirable.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。

From Dangal to Secret Superstar to the latest comedy-drama film BajrangiBhaijaan, Indian films have developed a solid fan base in China. Jumanji: Welcome to the Jungle Genre: adventure comedy The film follows four teenagers transported into the video game world of Jumanji, playing as the characters they choose.

Like many famous people of his age, Zhou experienced a lot. Yet he adopted a positive attitude to whatever happened in his life and set a perfect example telling us the pursuit of knowledge goes beyond age. He put forward the plan for the phonetic(语音的) pinyin for Chinese characters in the 1950s and continued his language studies until he was 85 years old in 1990; then he started to show concern for national and international affairs. Even after reaching the age of 100, he published at least five books and authored dozens of long articles, each of which had great influence. What makes his books and articles special is his courage to speak his mind whenever he was not satisfied with the reality. He blamed the so-called
