Send it to the host organizer in Q&A phase.BCafeterias have been filled with challenges—right from planning, purchasing, and preparing, to reducing waste, staying on budget, managing goods, and training staff. Through the tedious process, restaurateurs lacked a unified platform for efficient management. To bring consistency to the unorganised catering（餐饮）industry, childhood friends Arjun Subramanian and Raj Jain, who shared a passion for innovation, decided to partner in 2019 to explore opportunities in the cafeteria industry.In May 2020, they co-founded Platos, a one-stop solution for restaurants with a custom technology kit to streamline all aspects of cafeteria management. The company offers end-to-end cafeteria management, staff selection and food trials to ensure smooth operations and consistent service. "We believe startups solve real problems and Platos is our shot at making daily workplace food enjoyable again. We aim to simplify the dining experience, providing a convenient and efficient solution that benefits both restaurateurs and customers and creating a connected ecosystem, "says Subramanian, CEO and co-founder.Platos guarantees that a technology-driven cafeteria allows customers to order, pay, pick up, and provide ratings and feedback. It also offers goods and menu management to effectively perform daily operations. Additionally, its applications connect all shareholders for a smart cafeteria experience. "We help businesses that are into catering on condition that they have access to an industrial kitchen setup where they' re making food according to certain standards," Jain states.Since the beginning, Platos claims to have transformed 45 cafeterias across eight cities in the country. Currently, it has over 45,000 monthly users placing more than 200,000 orders. Despite facing challenges in launching cafeterias across major cities in the initial stages, Platos has experienced a 15% increase in its month-over-month profits.As for future plans, the startup is looking to raise $1 million from investors as strategic partners, bringing in capital, expertise, and networks. "Finding the right lead investor is the compass that points your startup toward success," Subramanian says.4. What does the underlined word "tedious" in Paragraph 1 mean?A. Time-consuming.B. Breath-taking.C. Heart-breaking.D. Energy-saving.5. What is the purpose of founding Platos?A. To connect customers with a greener ecosystem.B. To ensure food security and variety in cafeterias.C.

Tech-driven cafeterias have covered most urban areas.7. What is Subramanian's future plan for Platos?A. To reduce costs.B. To increase profits.C. To seek investment.D. To innovate technology.CWith a brain the size of a pinhead, insects possess a great sense of direction. They manage to locate themselves and move through small openings. How do they do this with their limited brain power? Understanding the inner workings of an insect's brain can help us in our search towards energy-efficient computing, physicist Elisabetta Chicca of the University of Groningen shows with her most recent result: a robot that acts like an insect.It's not easy to make use of the images that come in through your eyes when deciding what your feet or wings should do. A key aspect here is the apparent motion of things as you move. "Like when you're on a train,” Chicca explains. "The trees nearby appear to move faster than the houses far away." Insects use this information to infer how far away things are. This works well when moving in a straight line, but reality is not that simple. To keep things manageable for their limited brain power, they adjust their behaviour: they fly in a straight line, make a turn, then make another straight line.In search of the neural mechanism（神经机制）that drives insect behaviour, PhD student Thorben Schoepe developed a model of its neuronal activity and a small robot that uses this model to find the position. His model is based on one main principle: always head towards the area with the least apparent motion. He had his robot drive through a long passage consisting of two walls and the robot centred in the middle of the passage, as insects tend to do. In other virtual environments, such as a space with small openings, his model also showed similar behaviour to insects.The fact that a robot can find its position in a realistic environment is not new. Rather, the model gives insight into how insects do the job, and how they manage to do things so efficiently. In a similar way, you could make computers more efficient.In the future, Chicca hopes to apply this specific insect behaviour to a chip as well. "Instead of using a general-purpose computer with all its possibilities, you can build specific hardware; a tiny chip that does the job, keeping things much smaller and energy-efficient." She comments.8. Why is "a train" mentioned in Paragraph 2?A. To illustrate the principle of train motion.B. To highlight why human vision is limited.C. To explain how insects perceive distances.D. To compare the movement of trees and houses.9. What does Paragraph 3 mainly talk about concerning Schoepe's model?A. Its novel design.B. Its theoretical basis.C. Its possible application.D. Its working mechanism.10. What do the researchers think of the finding?A. Amusing.B. Discouraging.C. Promising.D. Contradictory.11. What will Chicca's follow-up study focus on?A. Inventing insect-like chips.B. Studying general-purpose robots.C. Creating insect-inspired computers.D. Developing energy-efficient hardware.DWith the help from an artificial language（AL）model, MIT neuroscientists have discovered what kind of sentences are most likely to fire up the brain's key language processing centers. The new study reveals that sentences that are more complex, because of either unusual grammar or unexpected meaning, generate stronger responses in these language processing centers. Sentences that are very straightforward barely engage these regions, and meaningless orders of words don't do much for them either.In this study, the researchers focused on language-processing regions found in the left hemisphere（半球）of the brain. By collecting a set of 1,000 sentences from various sources, the researchers measured the brain activity of participants using functional magnetic resonance imaging（fMRI）while they read the sentences. The same sentences were also fed into a large language model, similar to ChatGPT, to measure the model's activation patterns. Once the researchers had all of those data, they trained the model to predict how the human language network would respond to any new sentence based on how the artificial language network responded to these 1,000 sentences.The researchers then used the model to determine 500 new sentences that would drive highest brain activity and sentences that would make the brain less active, and their findings were confirmed in subsequent human participants. To understand why certain sentences generate stronger brain responses, the model examined the sentences based on 11 different language characteristics. The analysis revealed that sentences that were more surprising resulted in greater brain activity. Another linguistic（语言的）aspect that correlated with the brain's language network responses was the complexity of the sentences, which was determined by how well they followed English grammar rules and bow logically they linked with each other.The researchers now plan to see if they can extend these findings in speakers of languages other than English. They also hope to explore what type of stimuli may activate language processing regions in the brain's right hemisphere.12. What sentences make our brain work harder?A. Lengthy.B. Logical.C. Straightforward.D. Complicated.13. What is the function of the AL model in the research?A. To examine language network.B. To reduce language complexity.C. To locate language processing area.D. To identify language characteristics.14. How did the researchers carry out their study?A. By conducting interviews.B. By collecting questionnaires.C. By analyzing experiment data.D. By reviewing previous studies.15. Which of the following is a suitable title for the text?A. AL Model Stimulates Brain ActivitiesB. AL Model Speeds Up Language LearningC. AL Model Reveals the Secrets of Brain ActivationD. AL Model Enhances Brain Processing Capacity第二节（共5小题; 每小题2.5分, 满分12.5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。

The study. (22)_________ has yet to be published in a scientific Journal, adds another dimension to scientists(23)________ (grow)understanding of how plants detect and interact with their surroundings.In recent years, it has become very clear that plants are more sensitive than researchers (24)_________ (think). They respond when touched by insects and turn toward sources of light. “Plants are not just robotic stimulus-response devices,” said Frantisek Baluska of the University of Bonn in Germany. “They’re living organisms which have their own problems.”Actually making their suffering hearable, however, is another matter entirely.(25)________(test) that possibility, a team led by Itzhak Khait, a plant scientist at Tel Aviv University in Israel, placed microphones capable of detecting ultrasonic frequencies(超声波频率) four inches from tomato and tobacco plants. The researcher then either stopped watering them or cut their stems.Measuring in the range of 20 to 150 kilohertz (千赫) the researchers found that even happy healthy plants madethe occasional noise. But when cut, tobacco plants emitted (26)_________average of 15 sounds within an hour of being cut, (27)_________tomato plants produced 25 sounds.(28)_______researchers aren’t yet sure how plants produce these sounds, Khait and his colleagues proposed one possibility in their paper (29)____________as water travels through the plants' tubes, air bubbles will form and explode, producing small vibrations.All this “screaming” caused by stress wasn’t in a range detectable by human ears. But organisms that can hear ultrasonic frequencies like mice, bats or perhaps other plants (30)________possibly hear the plants cries from as far away as 15 feet.Section BDirections: Fill in each blank with a proper word chosen from the box. Each word can be used only once. Note that there is one word more than you need.Italians find “Moments of Joy in this Moment of Anxiety”It started with the national anthem. Then came the piano chords, trumpet blasts, violin serenades(小夜曲) and even the clanging of pots and pans--all of it (31)_________from people’s homes, out of windows and from balconies, and resounding across rooftops.Finally, on Saturday afternoon, a nationwide (32)__________of applause broke out for the doctors on the medical front lines fighting the spread of Europe’s worst coronavirus outbreak.Italians remain (33)_________under house arrest as the nation, the European front in the global fight against the coronavirus, has ordered extraordinary restrictions on their movement to prevent infection.But the music and noise erupting over the streets, from people (34)_________in their homes, reflects the spirit, resilience and humor of a nation facing its worst national emergency since the Second World War.To the extent that this is a virus that tries people' s souls, it has also demonstrated the (35)__________of those national characters.In China, patriotic truck drivers risked infection to bring(36)_________needed food to the people of Wuhan, the epicenter of the outbreak. In Iran, videos show doctors in full combat dress and masks dancing to keep (37)_______up. And in Italy, the gestures of gratitude and music ring out above the country’s empty streets, while social media feeds fill with (38)___________, sentimental and humorous web videos.Images of nurses collapsed from exhaustion or their faces bruised(使受瘀伤) from tightly(39)________maskshave also spread across the web in recent days. Parents posted pictures of unicorns and rainbows drawn by young children with the title “It will all be OK.”“We’re Italians, and loving singing is part of our culture,” said Giorgio Albertini, 51, an archaeology professor who clapped from his apartment balcony in the university district of Milan, calling it a way “to feel a community, and to have the (40)_________grief.”Ⅲ Reading ComprehensionSection ADirections: For each blank in the following passage there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.Making choices is hard. That would be why researcher Moran Cerf has (41)_________it from his life. As a rule, he always chooses the second menu item at a restaurant.This is (42)___________by his research in neuroeconomics(神经经济学)( a somewhat new, divisive field) at Northwestern University. As Business Insider describes, Cerf has extended his ideas which draw on some controversial ideas in psychology, including ego depletion out into a piece of advice that, to (43)_________happiness, people should "build a life that requires (44)________decisions by surrounding themselves with people who possess traits they prefer.On an instinctive level, Cerf’s idea (45)_____________: Many choices people make are the product of social pressures and the inputs of (46)___________people around them. One example Cerf furnishes is that, (47)________consistently ordering the second menu item. he never picks where to eat. Rather, he (48)________his decision to his dining partner which friend he plans to eat with, probably one he trusts and always lets them pick.While it's (49)__________what, if any, scientific principles underlie those pieces of advice, there is no shortage of research showing that choices can sometimes feel more(50)_______than liberating. An example from Quanta poits (假设): If you have a clear love of Snickers(士力架), choosing that over an Almond Joy(杏仁巧克力) or a Milky Way(牛奶巧克力) should be a(51)________. And, as an experiment conducted by neuroscientist Paul Glimcher at NYU shows, most of the time it is, (52)_________you introduce more choices. When the participants were offered three candy bars (Snickers, Milky Way, and Almond Joy) they had no problem picking their favorite, but when they were given the option of one among 20, including Snickers, they would sometimes drift away from their (53)_____. When the choices were taken away in later trials. the participants would wonder what caused them to make such a bad decision.As Quanta details, according to a model called" 'divisive normalization(分裂归一化), which has gained some popularity, the way the brain encodes choices has a lot to do with how it values all its options. So, if you have twothings that are clearly (54)___________, brain areas involved in decision-making fire in a pattern that makes the decision clear. When the choices are comparable. the brain does its best to focus on the distinctions between the two, but more choices (55)_________ that ability out.41.

A. crowd B. figure C. sort D. putSection BDirections: Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A. B. C and D. Choose the one that fits best according to the information given in the passage you have just read.(A)One spring day, once the flowers have begun to open, a bee will hover (盘旋)and zip through your yard and dive-bomb your picnic table. While you're thinking about avoiding an attack, that bee is focused on something else entirely: me.A honeybee has about six weeks to live. Today, like most days, her task is to fly as many as three miles from home. stick her long. straw like tongue into a hundred or so flowers. When the bee has had her fill. she’ll fly home. There the bee will deposit what she has got into the mouth of one of her co-workers, who will relay it to another, and so on for about 20 minutes, until the mixture is ready to be placed into the comb. Then she and her 50.000 or so mates will hover in the dark all night every night, flapping their wings to create hot, breezy conditions to remove the waterfrom the mixture. Several sunrises later, they will seal me off in a golden cell of beeswax. In her lifetime, our bee may visit 4,000 flowers, and yet will produce only one-twelfth a tea spoon of me.The average American consumes nearly a pound and a half of me every year, in tea, on toast, and beyond. If I do say so myself, I am a timeless treasure. Literally I never go bad.Unfortunately, my good health is not guaranteed. The problem lies in the growth of industrial agriculture and the use of pest control chemicals, as well as changes in weather patterns, all of which reduce the number of flowers bees have to visit. I’d appreciate your letting your own garden grow just a little wild. My future depends on all of us fostering spring and summers wild flowers, thus helping the bees, who give so much to you, to me without ever asking for anything in return.56. What does “me” refer to in the passage?A. The flower.B. The bee.C. Water. D Honey.57. What is the 2nd paragraph mainly about?A. Bees’ special talent.B. Bees’ hard work.C. Bees’ living environment.D. Bees’ social behavior.58. Which one of the following is true according to the passage?A. A bee will always prioritize attacking picnic lovers.B. Before “me” is sealed off in beeswax, the drying process can take a few nights.C. The lifework of a bee satisfies the average demand of an American consumer annually.D. Bees are more likely to visit those deliberately pest-controlled gardens59. What is the purpose of the passage?A. To appeal for help for honeybees.B. To talk about the history of a treasure.C. To put forward techniques for gardeners.D. To argue against the control of chemicals.(B)Get Your Unlimited Card at Cineworld CinemasEnjoy Unlimited FilmsWatch all the films you want at any Cineworld for just one monthly price.Being an Unlimited card holder gives you access to all the 2D films you canhandle for one monthly price.

If it extends further south overpopulated areas, such as southern Greenland, people would be at increased risk of sunburn. However, on current trends the hole is expected to disappear altogether in a few weeks.Low temperatures in the northern polar regions led to an unusual stable polar vortex(极地漩涡) and the presence of ozone-destroying chemicals such as chlorine(氯)in the atmosphere-from human activities caused the hole to form.“The hole is principally a geophysical curiosity.” said Vincent-Henri Peuch, director of the Copernicus Atmosphere Monitoring Service. “We monitored unusual dynamic(动态的)conditions, which drive the process of chemical depletion of ozone. Those dynamics allowed for lower temperatures and a more stable vortex than usual over the Arctic, which then triggered the formation of polar stratospheric(平流层的)clouds and the catalytic(催化的) destruction of ozone.”The hole is not related to the Covid-19 shutdowns that have dramatically cut air pollution and reduced greenhouse gas emissions. It is also too early to say whether the unusually stable Arctic polar vortex conditions are linked with the climate crisis, or part of normal stratospheric weather variability.Peuch said there were no direct implications for the climate crisis. Temperatures in the region are already increasing, slowing the depletion of ozone, and the hole will start to recover as polar air mixes with ozone rich air from lower latitudes. The last time similar conditions were observed was in spring 2011.While a hole over the Arctic is a rare event, the much larger hole in the ozone layer over the Antarctic has been a major cause for concern for more than four decades. The production of ozone depleting chemicals has been dramatically reduced, under the1987 Montreal Protocol(蒙特利尔协议), but some sources appear still to be functioning in 2018unauthorized emissions were detected from some areas.New sources of ozone depleting chemicals were not a factor in the hole observed in the Arctic, said Peuch. “However, this is a reminder that one should not take the Montreal Protocol measures for granted and that observations from the ground and from satellites are central to avoid a situation where the ozone destroying chemical level in the stratosphere could increase again.”63. What is the possible meaning of the underlined word “depletion”?A. replacement.B. consumption.C. increase.D. production.64. According to the passage, scientists are concerned about the hole because____________.A. it is expected to be a threat to the mankind.B. the new hole is caused by air pollution and greenhouse gas emissions.C. it may encourage further scientific research and environmental awareness.D. it wars us of an oncoming climate crisis.65. What can be learned from the last two paragraphs?A. The hole over the Arctic shares the same causes as the one over the Antarctic.B. Human activities are highly responsible for producing ozone-destroying chemicals.C. The Montreal Protocol has successfully prevented new emissions.D. Some new illegal emissions are to blame for the hole over the Arctic.66. The best title for the passage is probably_________.A. Record-size Hole Opens in Ozone Layer above the Arctic.B Actions Urgently Needed for a New Hole in Ozone Layer.C Environmental Disaster and International Cooperation.D. How a Hole in Ozone Affects our Life on Earth.Section CDirections: Read the following passage. Fill in each blank with a proper sentence given in the box. Each sentence can be used only once. Note that there are two more sentences than you need.People like to post their selfies(自拍照)on social media. To know more about it, scientists at Syracuse University in New York recently did a research and came up with some surprising findings.People who post selfies and use editing software to make themselves look better show behaviors connected to narcissism, the researchers said. (67)_________Makana Chock, a professor from Syracuse University. said because social media is mostly used by people to share unimportant information about their lives, it is a good place for people to “work towards satisfying their own vanity.” Those “likes” under their Facebook selfies make them feel good.(68)_________Some people feel “peer pressure” to post selfies and some follow the popular belief that if there is no picture of an event or experience. it did not really happen. “Anyway, it shouldn’t be seen as negative. People get sense of satisfaction especially when they get likes. And it does no harm,” Chock said.Other findings from the study include: There are no major differences on how often men and women post selfies and how often they use editing software. (69)_______Chock said posting selfies on social media is not all that different from what people have done for many years. On trips and special events, our parents and grandparents used cameras instead of phones to take photos. They would bring back photos to show friends and family. You had no choice but to look at them. You probably commented about how nice everyone in the photos looked, especially children and the person showing the photos. They were happy to hear your comments. (70)__________On social media, however, people can decide not to look at photos even if they click “like”.TV. Summary WritingDirections: Read the following passage, Summarize the main idea and the main point(s)of the passage in no more than 60 words. Use your own words as far as possible.It's natural to feel the need to control something when everything around you feels out of control, and you feel helpless. When a friend of mine first heard about the coronavirus outbreak. she got down on her hand. and knees and cleaned her kitchen floor. She told me, “My floor wasn’t even dirty, but doing something constructive made me feel in control and that I was holding on to my power, despite the desperate circumstances.”Your most powerful weapon against uncertainty is your perspective because nobody and no situation can take that from you unless you give it away. Your perspective can victimize or empower you. When you look for the upside in a downside situation and figure out what you can control and what you can't, it's easier to accept whatever is beyond your control.高三英语调研测试（试卷参考答案）I Listening ComprehensionSection A1-5 BDBCB6-10 CBCCDSection B11-13 AAC14-16 BAD17-20 ACDCII.

ATo compete with online sellers, traditional bookstores have tried everything to win customers. And it’s true that a great bookstore can encourage people to read in many ways. Here are some good bookstores in China and other countries that are worth a visit.Eslite Bookstore, TaipeiThe Eslite Bookstore is a cultural landmark in Taipei. It has fashion boutiques（精品店）, cafes, galleries and other spaces. It also holds lots of reading-related activities including exhibitions and talks with famous writers.Sanlian Taofen Bookstore, BeijingIt is 11:30 pm and getting late.

The bookstore runs 24 hours a day, and it’s the first bookstore of its kind in Beijing.Shakespeare & Company, FranceFrance doesn’t have Shakespeare but it has Shakespeare & Company. Many great writers used to meet here, such as Ezra Pound（US） and Ernest Hemingway （US）. Today, it helps young writers by allowing them to live and work here. Strand Bookstore, USStrand Bookstore is a second-hand bookstore. It sells used books for $2-3 （about 14-21 yuan） each. Sometimes you can find very old and rare books at Strand, for example, a Shakespeare book that was published in 1632. The book is worth $125,000 （about 861,000 yuan）!21.

Which column is this passage most likely to be taken from in a newspaper?A. Sports SpaceB. Literature & NovelC. Routine BusinessD. Tourist & DiscoveryBNearly twenty years after the first book came out, it is clear that Rowlingstill possesses a magical hold on her readers. According to Rowling, it was a liberating experience to write a novel for adults without any expectations and to get feedback from readers.Rowling’s story is one of rags to riches that began on a train journey from Manchester to London in the. U. K., when the idea of a boy attending a school of wizardry, the characters and situations came flooding into her mind. Born as Joanne, Rowling was always fascinated with fantasy stories and started writing them at a young age. Her first story at six was about a rabbit, named Rabbit, which came down with measles（麻疹）and was visited by many friends including the giant Miss Bee. However, as she grew older, the task of making a living consumed her as she did different jobs.The passing away of her mother, a failed marriage and a young child had pushed Rowling to the edge of depression, when the magical wizard rescued her. Consumed by the desire to finish the story, she worked in cafes when her infant daughter slept.When her first manuscript was completed, Rowling sent it to twelve publishing houses which rejected it. The credit went to a small publisher, who decided to go ahead when his eight-year-old daughter asked for more after reading the first chapter!At the request of the publisher who felt that boys may not read a mystery book written by a woman, Joanne changed her name to J. K. Rowling —the “K” in the initial stands for her paternal grandmother Katherine. The first book was released in June 1997 and within a year, won the prestigious（有名望的）Book of the Year award in the U. K. From then on, Rowling had found her calling and her books flew off the shelf within a day of them being released. Harry Potter had become a franchise, and the movies, toys and books have made Rowling into a billionaire.24. We can learn from the passage that ________.A. Rowling began writing fantasy after the failure of her marriageB. Rowling’s first story was about a boy attending a school of wizardryC. Rowling was crazy about fantasy stories at a young ageD. Rowling thought it not a great experience to write for adults25. What is NOT the cause of Rowling’s depression ac cording to the passage?A. The magical wizard.B. The death of her mother.C.

What we can learn from this passage about J.K. Rowling?A. J.K. Rowling is his original name.B. Rowling is a determined-minded woman.C. She was diagnosed with measles when she was six.D. She was famous enough for writing to make a living at a young age.CAre you an optimist（乐观主义者）or a pessimist（悲观主义者）? It seems that young people in China are more optimistic than youth in other countries. Varkey Foundation, a UK non-profit organization, did a survey between last September and October. It asked 20,000 young people in 20 countries including China, the United States and the United Kingdom how they think and feel about the world. The survey found that 53 percent of those questioned in China thinkthe world is becoming a better place, the highest percentage among the countries surveyed.When asked why they felt hopeful for the future, 93 percent of Chinese youth think it’s because of advances in technology. Medicine, renewable energy and computing may make life in the future easier. Some 64 percent of Chinese youth also think China is a good place to live. The biggest reason（29 percent）is that China is “a country in which anyone is able to get on if they work hard”.The survey also found young people in emerging economies are more hopeful about the future than those in developed countries. Following China, Indian youth were the second most optimistic（49 percent）. Those in France, Italy and Turkey are the most pessimistic. The rise of global terrorism worries them most.However, Chinese young people seem to worry about something else. As much as 82 percent of them worry about climate change. China is the only country out of the 20 in which climate change was the biggest cause of fear for future. Vikas Pota of the Varkey Foundation took this as a good thing. Chinese youths are more aware than anyone of how serious the climate problem is and will be pressing for change, he told the South China Morning Post.28. In the survey, about ________ felt hopeful about the world.A. 20 countriesB. 10,600 Chinese youthC. 20,000 young peopleD. 53 percent of Chinese youth questioned29. Which is NOT the reason why Chinese young felt hopeful for the future?A. Technology advances quickly in China.B. They have more abilities.C. China is a good place to live.D. Working hard always helps in China.30. What else did the survey find?A. Young people in developed countries are more optimistic.B. The Indian youth is the most pessimistic in the survey.C. Global terrorism worries the young in countries like Italy.D. About 80 percent of Chinese youth care most about jobs.31. The main idea of this passage is to tell us that ________.A. Chinese young people are more optimistic.B. The life in the future in China is easier.C. Chinese young people worry climate change most.D. The young people in developed countries are worried about terrorism. DDo you always struggle to understand others’ feelings? Perhaps you should listen to your heart.According to a team of scientists at Anglia Ruskin University in the UK, people who are more aware of their own heartbeat are better at understanding others’ emotions.Researchers have long suspected that this ability is important for understanding others’ thoughts and feelings.To test this theory, the British team asked 72 volunteers to count their own heartbeats without feeling a pulse（脉搏）. This aimed to see how aware they were of the feelings inside their own bodies.Then, the volunteers were shown video clips of social interactions（互动）, which tested their ability to read the minds of the characters.During the clips, they were asked questions that required an understanding of the emotions of a certain character - for example, “What is Sandra feeling?” In addition, they were asked questions that did not involve any emotions, such as “What is Michael thinking?” Th ey were also askednon-social questions, like “What was the weather like that evening?”The results showed that those who had counted their heartbeats most accurately were better at answering questions relating to the characters’ emotions. However, there was no link between the ability to feel what’s going on inside your body and questions that did not involve any emotions. Punit Shah, lead author of the study, used an example to explain this: If your colleague Michael is rude toward Sandra in public, your body processes （处理）this by increasing your heart rate. This may make you feel anxious and allow you to understand that Sandra is embarrassed.“If you do not feel your heart rate increase, it may reduce your ability to understand that situation and respond a ppropriately,” Shah told The Telegraph.Researchers believed their findings mean it could be possible to make people more empathetic by training them to listen to their hearts.This also lends support to the argument that feelings are, at the very least, deeply rooted in physical sensations（感觉）).32. What does the new study find?A. People are better at understanding others’ emotions than thoughts.B. People with quicker heartbeats are more sensitive to others’ feelings.C. The ability to feel your heartbeat is important for understanding others’ thoughts.D. Your ability to feel others’ emotions is related to your ability to feel your own heartbeat.33. Which of the following statements is TRUE about the new study according to the article?A. The volunteers were asked to count their heartbeats while watching video clips.B. Researchers designed emotional, non-emotional and non-social questions.C. The volunteers were required to describe each other’s thoughts and feelings.D. Researchers trained the volunteers to listen to their hearts and observed them.34. The underlined word “empathetic” in the second-to-last paragraph probably means _________.A. willing to accept ideas that are different from your ownB. not influenced in any way by other people or thingsC. being able to understand others’ feelingsD. willing to help those in trouble35. What can be concluded from the last four paragraphs?A. We react to a situation more slowly when our heart rates increase.B. Physical sensations in our bodies are believed to cause emotional changes.C. Our ability to feel emotions is part of us and can’t be changed.D. How we feel has nothing to do with the state of our bodies.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，选项中有两项为多余选项。

She sprang up when she saw me as if to get out of my way. Apologetically she explained that she was a cashier at a nearby store and was on her lunch break, trying to get a few needed items before her time was up.I r eassured her, “I am in no hurry. Go ahead and do what you need to do.” While she searched for a particular brand, she said that sometimes customers were rude to her at the store and she really appreciated my kindness. I told her that I had noticed cashiers being treated rudely by some people.I also explained to her that I was a retired nurse and understood some of what she was saying first hand. Sometimes patients, families, or doctors could be very rude or mean. But I tried to understand why they were feeling that way and let it go. “The world would be a better place if we all acted kindly toward each other. Those who are rude may have bad karma coming after them eventually.” I added.She nodded and was surprised, “So you know about karma?” My reply was simple. “A little bit. Karma is the same thing as doing something bad and it comes back to bite you on the butt.” She paused, looked puzzled, then broke out in a big smile and covered her mouth with her hand, laughing as she walked away.It felt so good that in a brief exchange I showed her there were kind people in the world, which might have helped her regain her faith in humanity.1.How did the lady react when she saw the author in the store?A. She apologized for her rude manners.B. She invited her to have lunch together.C. She stood up trying to make way for her.D. She kept searching for the needed product.2.Which of the following best describes the author?A. Kind and understanding.B. Courageous and warm-hearted.C. Responsible and humorous.D. Sympathetic and open-minded.3. What is the main message the author wants to convey?A. Working as a cashier is no easy job.B. Those who are rude deserve bad karma.C. Doing acts of kindness will make people feel good.D. We should treat others the way we want to be treated.【答案解析】 21-23 CAD1.C。
