And thishas great consequences on our health, our job performance, our relationships and our happiness. What is needed, she ly declares, is nothing short of a sleep revolution. Only by renewing our relationship with sleep can we take back control of our lives.In her bestseller Thrive, Arianna wrote about our need to redefine success through wellbeing, wisdom, wonder, and giving. Her discussion of the importance of sleep as a gateway to this more fulfilling way of living struck such a powerful chord (弦) that she realized the mystery and transformative power of sleep called for a fuller investigation (调查).The result is a scientifically sweeping and personal exploration of sleep from all angles, from the history of sleep, to the role of dreams in our lives, to the consequences of sleep deprivation (剥夺), and the new golden age of sleep science that is showing the vital role sleep plays in our every waking moment and every aspect of our health — from weight gain, diabetes, and heart disease to cancer and Alzheimer’s.In The Sleep Revolution, Arianna shows how our cultural removal of sleep as time wasted damages our health and our decision-making and our work lives and shortens our personal lives. She explores all the latest science on what exactly is going on while we sleep and dream. She decides the dangerous sleeping pill industry, and all the ways of our addiction to technology disturb our sleep. She also offers a range of recommendations and tips from leading scientists on how we can get better and more restorative sleep.In today’s fast-paced, always-connected and sleep-deprived world, our need for a good night’s sleep is more important than ever.

It helps to stress the value of sleep to success.CDoctors are known to be terrible pilots. They don’t listen because they already know it all, I was lucky: I became a pilot in 1970, almost ten years before I graduated from medical school. I didn’t realize then, but becoming a pilot makes me a better surgeon. I loved flying. As 1 flew bigger, faster planes, and in worse weather, I learned about crew resource management (机组资源管理), or CRM, a new idea to make flying safer. It means that crew members should listen and speak up for a good result, regardless of positions.I first read about CRM in 1980. Not long after that, an attending doctor and I were flying in bad weather. The controller had us turn too late to get our landing ready. The attending doctor was flying; I was safety pilot. He was so busy because of the bad turn, he had forgotten to put the landing gear (起落架) down. He was a better pilot—and my boss—so it felt unusual to speak up. But I had to: Our lives were in danger. I put aside my uneasiness sand said, we need to put the landing gear down now! That was my first real lesson in the power of CRM, and I’ve used it in the operating room ever since.CRM requires that the pilot/surgeon encourage others to speak up. It further requires that when opinions are from the opposite, the doctor doesn’t overreact, which might prevent fellow doctors from voicing opinions again. So when I’m in the operating room, I ask for ideas and help from others. Sometimes they’re not willing to speak up. But I hope that if I continue to encourage them, someday someone will keep me from landing gear up.8. What does the author say about doctors in general?A. They like flying by themselves.B. They are quick learners of CRM.C. They pretend to be good pilots.D. They are unwilling to take advice.9. The author deepened his understanding of the power of CRM when .A. his boss landed the plane too lateB. he was in charge of a flying taskC. he saved the plane by speaking upD. his boss operated on a patient10. In the last paragraph landing gear up probably means .A. following flying requirementsB. making a mistake that may cost livesC. listening to what fellow doctors sayD. overreacting to different opinions11. Which of the following can be the best title for the text?A. CRM: A New Way to Make Flying SafeB. A Pilot-Turned DoctorC. The Making of a Good PilotD. Flying Makes Me a Better DoctorDWe touch our faces all the time, and it had never seemed to be a big problem—until COVID-19 arrived. Touching our faces—the "T-zone" of our eyes, nose and mouth in particular—can mean giving ourselves the deadly virus.This is why organizations like the Centers for Disease Control and Prevention (CDC) have suggested that we avoid touching our faces. "Just stop this simple behavior," William Sawyer, founder of Henry the Hand, a nonprofitorganization that promotes hand hygiene (卫生), told The Washington Post. "It's the one behavior that would be better than any vaccine (疫苗) ever created."Yet, stopping this "simple" behavior might be harder than you think because it's already hardwired (固定存在于) into our system.Some face touchingis an automatic reflex (反射) —like when there is an itch (痒) on your nose, you'll scratch (挠) it without thinking. According to CNBC, a 2014 study found that touching your face also helps to reduce stress and regulate emotions. For example, you're more likely to do it when you feel awkward or embarrassed. According to Dacher Keltner, a psychologist at the University of California Berkeley, US, this action may also come with a social function: When you are talking to someone and want to change the subject, for example, touching your face is like "the curtains on a stage, closing up one act of the social drama, ushering (引导) in the next," Keltner told the BBC.Moreover, face-touching in almost all of these occasions is subconscious, which means it's very hard to change "because you don't even know you're doing it", said Sawyer. But you're not alone. In a 2015 study, wherea group of medical students were filmed in class, it was found that they touched their faces an average of 23 times an hour—with 44 percent of the touches being in the "T-zones". That was particularly surprising since medical students were supposed to know better.Since it's so hard to shake the habit, maybe the easiest way is to wash our hands more often. This way, we can be sure that our hands are free from the novel coronavirus.12. What do the first two paragraphs talk about?A. The best way to fight COVID-19B. How organizations are fighting COVID-19.C. Typical hand hygiene problems in the fight against COVID-19.D. The necessity to avoid touching our faces to fight COVID-19.13. Why is it hard for people to stop touching their faces?A. It makes people feel more confident.B. Many are unaware of this behavior's risks.C. They usually do it automatically and subconsciouslyD. Many think the action helps them express their emotions.14. Which of the following is a social function of touching faces, according to the text?A. Using it as a sign to change the topicB. Bringing a conversation to an end.C. Showing an interest in the ongoing subject.D. Making others feel relaxed while talking.15. What is the author's purpose in mentioning a 2015 study on a group of medical students?A. To give tips on how to stop touching faces.B. To prove that it is common for people to touch their faces.C. To show it is impossible to shake the habit of touching your face.D. To show how hygiene awareness helps people avoid touching their faces.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 RutgersUniversity study found that this mind and body combination, done twice a week for only two months,reduced the symptoms for a group of students by 40 percent.“We are excited by the findings because we saw such a meaningful improvement in both clinically depressed and non-depressed students,” said lead author Dr. Brandon Alderman. “It is the first time that both of these two behavioral ways have been looked at together for dealing with depression.”Researchers believe the two activities have an interactive effect on combatingdepression. Alderman and Dr. Tracey Shors discovered that a combination of mental and physical training (MAP) enabled students with major depressive disorder not to let problems or negative thoughts defeat them.Rutgers researchers say those who participated in the study began with 30 minutes of focused attention meditation followed by 30 minutes of oxygen sport. They were told that if their thoughts drifted to the past or the future they should refocus on their breathing, enabling those with depression to accept moment-to-moment changes in attention.Shors, who studies the productionof new brain cells in the hippocampus—part of the brain involved in memory and learning—says scientists have shown in animal models that oxygen sport exercise keeps a large number of certain cells alive.The idea for the human intervention (干预) came fromher laboratory studies, she says, with the main goal of helping individuals acquire new skills so that they can learn to recover from stressful life events.By learning to focus their attention and exercise, people who are fighting depression can acquire new learning skills that can help them process information and reduce the overwhelming recollection of memories from the past, Shors says.“We know these treatments can be practiced over a lifetime and that they will be effective in improving mental health.” said Alderman. “The good news is that this intervention can be practiced by anyone at any time and at no cost.”4. What made the research so different?A. Adopting a way of meaningful talk.B. Combining the two behavioral ways to treat depression.C. Treating depression with special medicine.D. Comparing the depressed with the non-depressed.5. The underlined word “combating” in Paragraph 3 can be replaced by ______.A. fightingB. identifyingC. distinguishingD. examining6. What did the participants do in the research?A. They did oxygen sport half an hour before thinking.B. They thought quietly and then took exercise.C. They took exercise longer than they thought.D. They took exercise while thinking quietly.7. What is Shors’ main purpose of her studies?A. To find out certain brain cells of humans.B. To study the production of new brain cells.C. To offer people a new method to treat stress.D. To decide the links between stress and exercise.CFrom Mozart to Metallica, tons of people enjoy listening to various types of music while they paint, write, or draw. Most believe that music helps increase creativity, but an international study conducted by English and Swedish researchers is challenging that view. The study results wereechoedby scientists fromLancasterUniversity, and theUniversityofGavle, saying their findings show music actually weakens creativity.To reach their conclusions, researchers had volunteers complete verbal problems designed to inspire creativity while sitting in a quiet room, and then again while music played in the background. They found that background music significantly weakened the volunteers’ ability to complete tasks connected with verbal creativity. The team also tested background noises like those commonly heard in a library, but found that such noises had no influence on subjects’ creativity.The tasks were simple word games. For example, volunteers were given three words, such as dress, rise, and flower. Then, they were asked to find a single word connected with all three that could be combined to form a common phrase or word. The single word, in this case, would be “sun” (sundress, sunrise, sunflower). Volunteers completed the tasks in either a quiet room, or while listening to two different types of music: rock music or light music“We found strong evidence of weakened performance when playing background music in comparison to quiet background conditions,” says co-author D. Neil McLatchie ofLancasterUniversity. He and his colleagues find that music negatively influences the verbal working memory processes of the brain, preventing creativity. Also, as far as the library background noises having seemingly no effect, the study’s authors believe that was the casebecause library noises create a “regular state” environment that doesn’t affect concentration.“To conclude, the findings here challenge the popular view that music increases creativity, and instead show that music, whatever type it is, is always a disadvantage for creative performance in problem solving,” the study reads.8. The underlined word in Paragraph 1 can be replaced by ________.A. challengedB. acceptedC. doubtedD. heard9. What were the volunteers asked to do in the study?A. To play music.B. To combine given words.C. To create new words.D. To connect words with music.10. What can we infer from the study?A. Quiet background inspires creativity best.B. Library noise does no harm to creativity.C. Music has a bad effect on language ability.D. Music types matter in creative performance.11. Which is the main idea of the passage?A. Quiet Environments Prevent Concentration.B. Background NoiseAffects Concentration.C. Composing Music Weakens Creativity.D. Listening to Music Reduces Creativity.DShe is one of mankind’s oldest ancestors and is more than three million years old. New analysis of the arm bones of Lucy, an early hominid, suggests she was a tree climber. Lucy’s remains were uncovered in Ethiopia in the 1970s, with the 3.18 million-year-old skeleton(骨骼)being the most complete of any upright, walking human ancestor. Since she was discovered, researchers have debated whether she spent her life in the trees or spent time walking on the plains as well.The new evidence from scans of her arm bones proves she spent time climbing and used her arms to pull herself up. The scans were compared with cross sections of humans and chimpanzees, which spend a mixture of time in trees and walking on all fours on the ground. They found that the arm bones were more heavily built, similar to those of chimps, while her lower limbs(下肢)would have meant she walked less efficiently than modern humans. Professor John Kappelman, atUniversityofTexas, believes the advantage of his study was that it focused on characteristics that reflect actual behavior during life, suggesting that evenwhen Lucy walked upright, she may have done so less efficiently than modern humans, limiting her ability to walk long distances on the ground.Previous studies suggested that Lucy was just 4 feet tall and weighed just 65 pounds. Combining the new data paints a picture of an ancestor who may have spent a great amount of her time in trees. It also expands onevidence from earlier this year which claimed that Lucy may have died from a fall, most likely from a tree. The evidence suggests Lucy may have spent time on the ground, returning to the safety of the trees for food and to sleep, to avoid her enemies.12. What did the researchers argue about after Lucy was discovered?A. Where she lived.B. How long she lived.C. What she ate.D. How she worked.13. How could people tell Lucy spent time climbing?A. By her walking style.B. By her heavily built arm bones.C. By her strong lower limbs.D. By her large cross sections.14. When Lucy walked, she may________.A. have walked with bigger stepsB. have walked at a faster speedC. have walked more efficiently than usD. have walked a shorter distance than us15. What is the main idea of the last paragraph?A. Guesses about Lucy’s characteristics.B. Some evidence of Lucy’s health.C. The safety of Lucy.D. The ancestor of Lucy.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学年成都大学附属中学高三英语下学期期末试卷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AThailand is a country with a long and rich history. It is also one of those countries which have many traditions which modern times fortunately have not affected. Thailand is famous for its unique culture. It is well worth noting that Thai culture hasbeen handed down from one generation to the next.Thai Classical DanceThe inspiring culture includes local music and wonderful Thai dances. The dances of course have something to do with its deep-rooted Buddhist religion, fighting arts and beautiful clothing. Thai classical dance performances are generally performed by gracious (高雅的) Thai ladies wearing beautiful Thai local costumes. Most resort (旅游胜地) areas and many hotels frequently offer these Thai culture dance shows for foreign visitors.Thai GreetingThe unique Thai gesture of greeting another person, the wai, is especiallyone of the great aspects of Thai culture. The wai is when a person joins both hands to either head or chest level while bending their head slightly towards his hands. This way of greeting is especially done when a younger person greets an older person and it indicates a sign of respect to their elders. Employees would also wai their managers even if the manager would be younger than themselves.BangkokBangkok is the culture center of Thailand and has been the Thai capital since the end of the eighteenth century. Observing Thai culture in Bangkok can be great experience as the combination of modern times and traditions have created a kind of unique atmosphere. Bangkok offers a package of Thai culture which is shown by numerous beautiful Buddhist temples and many examples of modern Thai architecture.Bangkok National MuseumAnother location in Bangkok where one can enjoy and see Thai culture is at the famed Bangkok national museum, which offers tourists an opportunity to view national treasures and unique Thai art pieces with its culture feature dating back as early as the late sixteenth century.1.Thai classical dance is related to ________.A.its living level and educationB.its history and architectural styleC.its customsD.its religious belief2.In Thailand a worker uses the gesture, the wai , to greet________.A.his close friend.B.a young stranger.C.his younger colleagues.D.his young boss.3.What make Thai culture in Bangkok so unique?A.The long history and fine weather of Bangkok.B.The mixture of the modern culture and traditions.C.A number of beautiful Thai Buddhist templesD.Many examples of modern Thai architecture.BHow much do consumers care about the carbon footprint of the products they buy? Would they care more if the goods were labeled with emissions(排放物)data?Does it matter at which stage in the lifecycle of a product the carbon is emitted? Research published in the International Journal of Environmental Policy and Decision Making offers a way to find out.Study participants view a carbon footprint label as similar to labels that have appeared on some existing products.The label shows the carbon dioxide emissions connected with their production, transportation, usage and disposal(清理), thus showing the buyer the likely effect on climate change of buying a particular product.In the first group of studies, the research team proved that carbon emissions and a carbon emissions label would indeed play a role in consumer product decisions, although not as great a role as price.In a second set of studies, the team found that emissions connected with usage were most important to consumers followed by the transportation and disposal stages.The carbon footprint of the producing process was considered less important to consumers than the other stages in the product's lifecycle because it is outside the consumer's control.That is, the participants felt they were less responsible for carbon emitted during producing process.Consumers value recycling a product, but the researchers found that, overall, the consumers would preferproducers to offset(补偿)carbon emissions rather than having toaddressthe problem directly themselves.Consumers are increasingly concerned with climate change problems, and already carbon labeling is appearing on some products."We find that participantsnot only take the carbon label into account when making product decisions, but they want detailed information on the label," the researchers explain.They suggest that companies should prepare for how carbon emissions labels might affect future consumer choice.4. Which of the following most affects consumer's choice?A. Labels.B. Price.C Packaging. D. Carbon footprint.5. About the carbon dioxide emissions in the product's lifecycle, which stage do consumers care most?A. Usage stage.B. Transportation stage.C. Disposal stage.D. Producing stage.6. Which of the following can best replace the underlined word "address"?A. Look into.B. Point out.C. Deal with.D. Run into.7. What can be inferred from the last paragraph?A. Companies should take carbonemissions more seriously.B. All products have been labeled with carbon emissions data.C. Producers will attach less importance to carbon emissions labels.D. Products labeled with carbon emissions data will have poor sales.CPablo Picasso was born on October25 inMalaga. Spain in 1881. Taking after his father, Picasso shared apassion(热爱)for painting and art. Even though he wasn't the best student in school, Picasso excelled at drawing. Noticing his amazing talent, Picasso's father, an artist, taught him everything he knew. Before long, Picasso could paint and draw much better than his father. With this rich talent, Picasso paid less and less attention to his schoolwork and spent the majority of his day sketching and drawing in notepads and sketchbooks.When he was a little bit older, Picasso moved twice and was accepted into two fine art programs. However, he didn't care very much for the special techniques they taught and often wandered the streets by himself drawing the scenes around him. After moving to these two places, Picasso moved back home toBarcelonaand decided that he would develop new techniques of art and painting based on what he saw.Later, Picasso decided to move toParis,France, where he began perfecting his own techniques of painting, drawing and other forms of art. His drawings. paintings, and an included pieces about sadness, poverty, classics and self-portraits. One of his major types of work is calledcubism(立体派),which includes art with all sizes of geometric shapes together on the piece of an. This type of art is very important because no other artists had come up with the idea before. Picasso decided to try something new, and as a result, cubismis widely accepted today as a classic style of art.Picasso inspires us to always be thinking.

Picasso is a highly creative artist.DWhen Alex Linwas 11 years old, he read an alarming article in the newspaper, which said that people were burying old computers in backyards, throwing TVs into streams, and dumping (丢弃) cell phones in the garbage. This was dangerous because e-waste contains harmful chemicals that can leak into the environment, getting into crops, animals, water supplies and people.Alex was really worried and decided to make it next project for WIN-the Westerly Innovations Network. Alex and six of his friends had formed this organization to help solve community problems two years before.But what could they do about this project with e-waste? The team spent several weeks gathering informationabout the harmful chemicals in e-waste and their effects on humans. They learned how to dispose(处置) of e-waste properly and how it could be recycled. Then, they sent out a Survey and found only one in eight know what e-waste was, let alone how to properly dispose of it.Alex and his friends went into action. They advertised in the local newspaper and distributed notices to students, asking residents to bring their unwanted electronics to the school parking lot. The drive lasted two days, and they collected over 9, 500 kilograms of e-waste. The next step was to set up a long-term e-waste drop-off center for the town. After some research, they’d learned that reusing is the best way to deal with electronic devices and it is seven times more efficient than recycling. So, they began learning to retrofit (翻新) computers themselves and distributed them to students who didn’t have their own. In this way, they could help students in the area and protect the environment at the same time.For a lasting solution to e-waste, the drop-off center wasn’t enough. Lawswould have to be passed. In 2016, WIN helped push for an e-waste bill in their town, which required companies that manufactured or sold electronics to take back e-waste. The bill clearly forbids the dumping of e-waste.

National GeographicBFollowing the Famous Silk RoadsThe Silk Roads were a networkof ancient trade routes that extended from East Asia all the way to theMediterranean. A key section of the Silk Roads is the Chang’an-Tianshan corridor(走廊), whichstretchesover a distance of around 5,000 kilometres through China, Kazakhstan and Kyrgyzstan, covering a total of 8,700 kilometres of trade routes. The three countries jointly pursued an application for UNESCO World Heritage (遗产) status which contained detailed research on the 33 sites along the corridor. This made history as the first successful multinational World Heritage application.The starting point of the corridor and the entire Silk Roads network isXi’an, inShanxiProvince. Further west on the Silk Roads, the geography gradually changes from wild deserts to high, snow-capped mountains to vast grasslands as the routes pass through theTianshanMountainsand emerge in the valleys ofCentral Asia. Although the Chang’an-Tianshan corridor of the Silk Roads ends here, the network continues westwards until it reaches theMediterranean.The corridor began to develop in the 2nd century. Assigned by the emperor, the ambassador Zhang Qian journeyed from Chang’an toCentral Asia, seeking to build bridges between the Han Dynasty and the Western Regions. Following Zhang’s efforts, trade routes took shape and relationships were strengthened between the major powers of the time, with the routes network reaching as far as theRoman Empire.Economic activities along the routes network were not limited to trade in silk. They contributed many other items to the marketplace of goods. The routes were busy with camels carrying loads of goods and businessmen selling everything imaginable.China’s exports included silk, porcelain, ironware and tea, while horses, jewellery, spices and grapes were all imported over vast distances from the West.In addition to trade exchange, the network served as a bridge for cultural exchange which shaped the evolution of science, art, technology and many other areas in societies along the network. Astronomy and mathematics were introduced toChinafromIndiaandArabia; important Chinese inventions such as papermaking and printing were brought to the West.All of these activities contributed to a great age of expansion as trade and cultural exchanges gave peopleaccess to new goods,knowledge and ideas. These routes connected Eastern and Western civilizations, which achieved a shared development. The addition of the Chang’an-Tianshan corridor to the UNESCO World Heritage List is a milestone in recognition of the Silk Roads as a crucial part of humanity’s common heritage.4.

Li Xiumei used to be in charge of a division at a company in Hangzhou, and her husband was a sales director. It was an ordinary situation where Li’s husband was on business trips a lot and Li worked overtime on weekends. City life sometimes is not easy.In 2018, they quit jobs and went back to Dongtianmu village, which lies in a forest of bamboo. The first time they drove into the village was one late afternoon. The cooking smoke was rising from the foot of the mountain, which gave them a very different feeling form thecity.The homestay was built beside her husband’s old countryside house. The old house is preserved (保留), while a brand-new building was built on its side and the whole site is made up of for courtyards. It has been updated tohave a hall, a tea room, a kitchen, a dining room. Japanese cherry trees are planted in the east courtyard. A swimming pool is placed in the west courtyard, with a bar located on one side.Li and her husband love gardening and music, and their new home gives them enough space to continue their interests and relax in the heart of nature. Li wants to share the quiet country life, so she makes her new home a homestay. In 2019, the homestay became an online hit after guests shared their experiences on social media. “The longer I stay here, the more I feel it was the right choice to come back, and this is more meaningful than making money,” Li says.8.

Living in the countryside.D. Developing the economy of cities.DFor centuries , tea has been used for far more than quenching thirst. Around the world people drink it to relax, reinvigorate and relieve, and it's something we need now more than ever.Even in the United States, a long coffee-dominated country, tea drinking is growing in popularity, with the country consuming 0.4 kilograms (14 ounces) of tea leaves per person a year compared with 0. 36 kilograms(12. 7 ounces) in 2007 according to the United Nations, as people switch away from soda,milk and fruit drinks.Scientists are beginning to look into just how tea might affect mood and cognition. Specifically, they're investigating whether its relaxing and refreshing effects are a direct biological outcome of the compounds in tea or whetherthey come from the context in which the drink is consumed—preparing your tea, choosing your favorite cup and sitting down for a brief break from the world. Or both.Drinking green tea has been found to improve brain function in healthy people, said Stefan Borgward, chair and director of the department of psychiatry and psychotherapy at the University of Lubeck, Germany.In a 2014 study, he gave one or two cups of green tea to 12 healthy volunteers and imaged their brains to analyze changes in connectivity inside certain brain regions.“We noticed an increased connectivity in regions of the brain associated with working memory,” he said via email.And a 2017 review of more than 100 studies he coauthored found that green tea can impact the brain in three ways: It can influence psychopathological state such as reducing anxiety; cognition by benefiting memory and attention; and brain function, specifically memory.That review concluded that "it would be desirable" for more Westerners to consume at least 100 milliliters(3.3 fluid ounces) of green tea each day “to protect neurocognitive function.”However, Borgward, cautioned that the effects aren't large, and the evidence is mainly provided by small-scale studies.12. How does the author introduce the tendency of drinking in the U.S.?A. By showing examples.B. By explaining reasons.C. By making a comparison.D. By checking existing facts.13. What is paragraph 3 mainly about?A. Scientists are looking into why tea makes people relaxed and refreshed.B. The context in which the drink is consumed is very important.C. People's relaxation is the direct biological outcome of the ingredients in tea.D. Preparing tea, choosing a cup and sitting down for a brief rest is amazing.14. What can we conclude from Stefan's research?A. Tea is a cure for a neurocognitive disease.B. Green tea is particularly beneficial to our memory.C. Drinking tea every day can prevent us from getting ill.D. Westerners drink less than 100 milliliters of green tea.15. What is the researcher'sattitude towards the finding?A. SupportiveB. Doubtful.C. Unclear.D. Objective.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。

All those pixels (像素) take up a lot of room if they are stored on personal computers or s phones, which is one reason why many people store their images in the cloud. But unlike a hard on drive which can be encrypted to protect its data, cloud storage users have to trust that a tech platform will keep their private pictures safe. Now a team of Columbia University computer scientists has developed a tool to encrypt (加密) images stored on many popular cloud services while allowing authorized users to browse and display their photographs as usual.Malicious (恶意的) attempts to access or leak cloud-based photographs can expose personal information. In November 2019, for example, a bug in the popular photograph storage app Google Photos mistakenly shared some users' private videos with strangers. Security experts also worry about employees at cloud storage companies on purpose accessing users' images.So the Columbia researchers came up with a system called Easy Secure Photos (ESP), which they presented at a recent conference. “We wanted to see if we could make it possible to encrypt data while using existing services,”says computer scientist Jason Nieh, one of the developers of ESP. “Everyone wants to stay with Google Photos and not have to register on a new encrypted-image cloud storage service.”To overcome this problem, they created a tool that preserves blocks of pixels but moves them around to effectively hide the photograph. First, ESP's algorithm (算法) divides a photograph into three separate files, each one containing the image's red, green or blue color1 data. Then the system hides the pixel blocks around among these three files (allowing a block from the red file, for instance, to hide out in the green or blue ones). But the program does nothing within the pixel blocks, where all the image processing happens. As a result, the files remain unchanged images but end up looking like grainy black-and-white ones to anyone who accesses them without the decryption (解密) key.4. What's probably the main purpose for people to store images in the cloud?A. To save storage room.B. To make photos beautiful.C. To try a new storage way.D. To keep their privacy safe.5. Why might employees in cloud storage companies be distrusted by experts?A. They sell users' passwords.B. They have invented new tools.C. They often let out personal information.D. They may steal a glance at users' images.6. What's the advantage of ESP?A. It can provide clear images.B. It can decrease the upload time.C. It can classify images automatically.D. It can encrypt data on the original platform.7. What does paragraph 4 mainly talk about?A. Method of decryption.B. Image-processing technique.C. Separate files of images.D. Data analysisof color1 s.CWith graduation days being celebrated all over the country, a student who has to use a wheelchair honored his mother on his graduation day in a special way. Easley High School graduate, Alex Mays surprised people present when he got up and walked across the stage at Clemson's Littlejohn Coliseum.“I was really happy—it made me feel good,” Alex said.Alex was not given a chance to live right from his birth. He was born at 25 weeks and weighed just 1 pound, 10 ounces at birth. When he was very young, he had a disease and lost the ability to walk. After his mother's death in 2013, Alex had several other difficult life changes until he came to live with his grandparents, Dousay and her husband, Dewayne. Dousay said that when Alex came to live with them, they decided to bring him up in the best possible way they could.Last fall, Alex said that he would walk across the stage to get his diploma to honor his late mother. He practiced hard and worked with a physical therapist for 9 months to complete his plan.The only help Alex got was from his mom's best friend, Tonya Johnson, who pushed his wheelchair to the stage wearing one of his mother's favorite shirts. “I had support from my family. I couldn't have done it without them,” Alex said.“Alex made everyone in the building feel encouraged that day” Pickens County School District public information specialist John Eby said. “The school teachers knew he was going to get up to get his diploma, but the distance he walked was a surprise, even to them,” Eby said.“Some of life's most important tests aren’t given in a classroom; Alex tested himself and passed with flying color1 s,” Eby added.8. In what way did Alex honor his late mother on his graduation day?A. By dressing like her.B. By saying sorry to her.C. By inviting her best friend.D. By walking to get his diploma.9.

Onewas 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.

2021年成都大学附属中学高三英语下学期期末考试试卷及答案
2021年成都大学附属中学高三英语下学期期末考试试卷及答案第一部分阅读(共两节,满分40分)第一节(共15小题;每小题2分,满分30分)阅读下列短文,从每题所给的A、B、C、D四个选项中选出最佳选项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 HospitalsBYou've probably heard it suggested that you need to move more throughout the day, and as a general rule of thumb, that "more" is often defined as around 10,000 steps. With many Americans tracking their stepsvia new fitness-tracking wearables, or even just by carrying their phone, more and more people use the 10,000-step rule as their marker for healthy living. Dr. Dreg Hager, professor of computer science at Johns Hopkins, decided to take a closer look at that 10,000-step rule, and he found that usingitas a standard may be doing more harm than good for many.“It turns out that in 1960 in Japan they figured out that the average Japanese man, when he walked 10,000 steps a day burned something like 3,000 calories and that is what they thought the average person should consume so they picked 10,000 steps as a number” Hager said.According to Hager, asking everyone to shoot for 10,000 steps each day could be harmful to the elderly or those with medical conditions, making it unwise for them to jump into that level of exercise, even if it's walking. The bottom line is that 10,000 steps may be too many for some and too few for others. He also noted that those with shorter legs have an easier time hitting the 10,000-step goal because they have to take more steps than people with longer legs to cover the distance. It seems that 10,000 steps may be suitable for the latter.A more recent study focused on older women and how many steps can help maintain good health and promote longevity (长寿).The study included nearly 17,000 women with an average age of 72. Researchers found that women who took 4,400 steps per day were about 40% less likely to die during a follow-up period of just over four years: Interestingly, women in the study who walked more than 7,500 steps each day got no extra boost in longevity.4. What does the underlined word "it' in Paragraph 1 refer to?A. The phone recording.B. The 10,000-step rule.C. The healthy living.D. The fitness-tracking method.5. What does Paragraph 2 mainly talk about?A. How many steps a Japanese walks.B. How we calculate the number of steps.C. If burning 3,000 calories daily is scientific.D. Where 10,000 steps a day came from.6. Who will probably benefit from 10,000 steps each day according toHager?A. Senior citizens.B. Young short-legged people.C. Healthy long-legged peopleD. Weak individuals.7. How many steps may the researchers suggest senior citizens take each day?A. 4,400 steps.B. 10,000 steps.C. 2,700 steps.D. 7,500 steps.CWhen I was a boy, there was but one permanent ambition among my comrades in our village on the west bank of Mississippi River. That was, to be a steamboat man. We had temporary ambitions of other sorts, but they were only temporary.My father was a justice of the peace, and I supposed he possessed the power of life and death over all men and could hang anybody that offended him. This was distinction enough for me as a general thing;butthe desire to be a steamboat man kept intruding, nevertheless. One of our boys in town, who went away and was not heard of for-a long time, turned up as apprentice engineer on a steamboat. This thing shook the bottom out of all my Sunday—school teachings. That boy was notoriously worldly, and I was just the opposite. There was nothing generous about this fellow in his greatness. He would always manage to have a rusty nail to scrub while his boat stopped at our town, and he would sit on the inside guard and scrub it, where we could all see him. And wherever his boat was laid up he would come home and show off in the town in his blackest and greasiest clothes, so that nobody could help remembering that he was a steamboat man; and he used all sorts of steamboat technical terms in his talk, as if he were so used to them that he forgot common people could not understand them.This creature's career could produce but one result, and it was speedily followed. Boy after boy managed to get on the river. Despite many choices, pilot was the grandest position of all. The pilot, even in those days of trivialwages, had a princely salary—from 150—250 dollars a month, and no board payment.But our parents would not let us and our worry was the next year would find us hunting for jobs with low pay again. So by and by I ran away. I said I never would come home again till I was a pilot and could come in glory.8. Why does the writer mention his father's job in Paragraph 2?A. To show that his father was in power.B. To show that his father is cruel.C. To emphasize the job he prefers.D. To emphasize his love for his father.9. Which of the following can best conclude the writer's attitude toward the boy?A. He thought the boy was material but pitiful.B. He thought the boy was annoying but still envied him.C. He thought the boy was shallow but knowledgeable.D. He thought the boy was disrespectful but still liked him.10. Which of the following statements is Not True?A. The boy talked in a way to make others feel jealous.B. The boy's experience made other boys follow suit.C. The pilot's salary was ly high but without meals covered.D. The writer was ambitious to make his childhood dream come true.11. What rhetorical method does the underlined sentence have?A. Simile.B. Personification.C. Parallelism.D. Irony.DBrain 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, comparedwith 35 percent when the mice were awake. Study co-author Thomas Kilduff, director of the Center for Neuroscience at SRI International, told Newsweek the team was surprised to find that mice performed better on learning and memory tasks when the MCH cells were prevented. “This result suggests that activation of the MCH neurons may affect memory — that is, MCH neurons may facilitate forgetting,” Kilduff explained.When asked what motivated the study, Kilduff said, “We hope the work could deepen our understanding of Alzheimer’s disease. Understanding the neural basis of learning and memory is a huge area of neuroscience research because of its effects on our everyday lives, as well as diseases such as Alzheimer’s disease. Prior to this work, no one suspected that MCH neurons had anything to do with forgetting,” said Kilduff.12. What can we infer from paragraph 1?A. Forgetting is a passive process.B. The forgetting process is known to us.C. Some memories are forgotten while we are awake.D. Certain memories are removed while we are asleep.13. What does the underlined word “them” in paragraph 2 refer to?A. REM sleep patterns.B. Past researches.C. MCH neurons.D. A range of functions.14. Why did Kilduff’s team conduct the research?A. To publish the study in the journal Science.B. To know more about Alzheimer’s disease.C. To contribute to human’s forgetting.D. To explore our everyday lives.15. What can we know about MCH?A. MCH cells takes control of REM sleep patterns .B. MCH neurons may disturb memory consolidation.C. MCH neurons have nothing to do with forgetting.D. MCH cells help mice performing better on learning.第二节(共5小题;每小题2分,满分10分)阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。

It is based on an ancient Chinese girl who dresses up herself as a man so that she can join the army.Director Niki Caro and the actors show us wonderful battle scenes and Chinese Kung Fu.OnwardDragons, unicorns (独角兽) and other creatures are usually considered to only exist in ancient Greece, but in Onward, they are all still alive and kicking in the UStoday. Onward is about two brothers who go on a road trip in order to bring their father back from the dead. It is such a perfect film that it’s worth spending a few hours in the cinema.RadioactiveRadioactive tells us about a famous Polish-French scientist, Marie Curie who won the Nobel Prize twice but was finally killed by the radiation she studied. In the film. Curie is played by Rosamund Pike alongside Sam Riley as her husband Pierre Curie and Anya Taylor-Joy as their daughter Irene.MisbehaviorThe Miss World Beauty Contest may be out of fashion, but it used to be one of television’s biggest events.Misbehaviortells what happened when the event was staged at the Royal Albert hall in London in 1970. There could hardly be a more interesting topic for a film, even if it was set 50 years ago.1. What do we know about Onward?A. It praises a woman fighter.B. It is a Chinese story.C. It focuses on animal protection.D. It is a film about magic.2. Who does Rosamund Pike play?A. A soldier.B. A killer.C. A scientist.D. A designer.3. Which of the following films is set in the UK?A. Misbehavior.B. Onward.C. Radioactive.D. Mulan.BScientists often compare coral reefs(珊瑚礁) to underwater rainforests, yet unlike the leafy plant base of a forest, corals are animals. The soft creatures are naturally half-transparent and get their brilliant color1 from algae(藻类) living inside them. When corals experience stress from hot temperatures or pollution, theyhaltthe interdependent relationship with algae, typically pushing them out and turning white. Corals are still alive when they are white, but they're at risk and many eventually die, turning dark brown.Scientists around the world are looking for means to protect and maybe increase corals. One common option is to create more protected areas — essentially national parks in the ocean. Beyond nature preserves, some conservationists are looking to more hands-on methods. One research center in the Florida Keys is exploring a form of natural selection to keep corals remaining. The reef system in the Keys has been hit hard by climate change and pollution, which is especially tough, because corals there help support fisheries worth $ 100 million every year.To keep the wild ecosystem alive, Erinn Muller, the center's director, and her team are harvesting samples of the corals that survived the environmental stress naturally, keeping them to make them reproduce, and then reattaching them to the reef. They have 46,000 corals on plastic frames under the sea. So far, the center has regrown over 70,000 corals from five different species on damaged reefs.In The Bahamas, Ross Cunning, a research biologist at Chicago's Shedd Aquarium, focuses on corals with genes that could make them natural candidates for restoration projects. He published a study of two Bahamian reefs, one that survived an extreme 2015 heat wave, and one that didn't. "We think their ability to deal with these higher temperatures is built into their genes," says Cunning. There's evidence of corals evolving more quickly to resist rapidly warming climate. The big question scientists need investigate, adds Gunning, is how much more heat corals can adapt to.4. What does the underlined word "halt" in the first paragraph mean?A. End.B. Develop.C. Strengthen.D. Weaken.5. What do Muller and her team do to save corals?A. Restore the damaged reefs.B. Grow corals by hand underwater.C. Create more protected areas.D. Move corals to unpolluted areas.6. What do Gunning's words suggest?A. Many corals have been genetically improved.B. Cooling down the waters is key to rescuing corals.C. Reasons for corals surviving heat waves are shocking.D. The highest temperature corals can survive is unclear.7. Which can be a suitable title for the text?A. Relationship between corals and algaeB. Efforts made to save coralsC. Impact of climate warming on coralsD. Survival crisis faced by coral reefsCThe outbreak of the novel corona virus pneumonia (NCP) has disrupted the lives and work of nearly every Chinese person. However, a new trend has been on the rise: many have turned themselves into livestreaming users orfollowers.According to Questmobile, a professional big data intelligence services provider in China, the audience for Douyin, Kuaishou and other livestreaming platforms surged to 574 million during the Spring Festival holiday, up 35 percent from 2019.Confined at home, away from their friends and loved ones, people turn to livestreaming to reach out to the world. For them livestreaming can help them share their lives and interest with a global audience, which will give them the sense of being “in the moment”. Even as viewers, they can also engage immediately with livestreamers by commenting and making suggestions.“When I comment on the livestreaming videos, I’m not simply an audience member, but also an active part of the program. That gives me a sense of engagement,” an Internet user named Wang Hao told People’s Daily.Livestreaming is not only for fun, but also a new tool for many businesses. Affected by the pandemic, many businesses had to stop their sales in physical stores. To meet their business goals and survive during these trying times, many chose to livestream to revive their businesses.Joyoung, a leading maker of small kitchen appliances, is a good example. The company not only added a number of broadcasts each day to advertise their products, but also shared the menus that were beneficial to health. “The responses to our livestreaming shows have been well beyond expectations,” Kang Li, who oversees the company’s livestreaming unit, told China daily. “It’s a natural opportunity to truly bond with our followers.”Like it or not, livestreaming is likely to go mainstream in China for both entertainment and business.8. What is the purpose of writing the second paragraph?A. To introduce some popular livestreaming platforms in China.B. To report data on the development of livestreaming in 2019.C. To show that Chinese people spend too much time on livestreaming apps.D. To prove that livestreaming are becoming increasingly popular in China.9. What does Wang Hao think of commenting on livestreaming?A. It is boring to make comments.B. It is the only way to share viewers’ lives.C. It makes people feel involved in the stream.D. It helps livestreamers improve themselves.10. What do paragraphs 5&6 mainly talk about?A. Livestreaming replaced physical stores in many areas.B. Many businesses turned to livestreaming platform for marketing.C. Livestreaming platforms faced challenges during the pandemic.D. Livestreaming platforms made changes to their services.11. How does the author feel about thefuture of livestreaming?A. Positive.B. Uncertain.C. Disappointed.D. Confused.DA satellite is about to demonstrate a new way of capturing space junk with magnets for the first time. With the frequency of space launches dramatically increasing in recent years, the potential for a disastrous collision above Earth is continually growing. Now, Japanese orbital clean-up company Astroscale is testing a potential solution.The firm's End-of-Life Services by Astroscale demonstration mission is scheduled to lift off on 20 March aboard a Russian Soyuz rocket. It consists of two spacecraft: a smal “client” satellite and a larger “servicer” satellite, or “chaser”. The smaller satellite is equipped with a magnetic (磁力的) plate which allows the chaser todock withit.The two stacked spacecraft will perform three tests once in orbit, each of which will involve the servicer satellite releasing and then recapturing the client satellite. The first test will be the simplest, with the client satellite drifting a short distance away and then being recaptured. In the second test, the servicer satellite will set the client satellite tumbling before catching up with it and matching its motion to grab it.Finally, if those two tests go well, the chaser will live up to its name by letting the client satellite float a fewhundred metres away before finding it and attaching to it. All of these tests will be performed autonomously, with little to no human input once they are set in motion.“These kinds of demonstrations have never been done before in space - they are very different to, say, an astronaut controlling a robotic arm on the International Space Station,” says Jason Forshaw at AstroscaleUK.“This is more of an autonomous mission.” At the end of the tests, both spacecraft will burn up in Earth's atmosphere.If companies wanted to use this capability, they would have to attach a magnetic plate to their satellites so they could be captured later. Because of the growing space garbage problem, many countries now require firms to have a way to bring back their satellites once they run out of fuel or fail, so this could be a fairly simple likely plan, Forshaw says. Right now, each chaser can only nab one satellite, but Astroscale is working on a version that could drag three or four out of orbit at once.12. Which of the following can replace the underlined word "dock with" in Paragraph 2?A. Deal with.B. Keep up with.C. Join together.D. Crash.13. Why many countries now require firms to have a way to bring back their satellites?A. Because of the growing space waste problem.B. Because the frequency of space launches are dramatically increasing.C. Because they can earn large profits from it.D. Because Astroscale has found a new method of capturing the space garbage.14. What will Astroscale do to solve the space junk problem?A. An astronaut controls a robotic arm on the International Space to capture the “client” satellite.B. Through a magnetic plate remotely controlled by humans on the ground to catch the “client” satellite.C. Finding the "client "satellite and attaching to it with a magnetic plate automatically.D. Tumbling to match the motion of “client satellite the drag three or four satellites out of its orbit into atmosphere.15. What can we infer from the passage?A. People will bum the space junk up in Earth's atmosphere in the future.B. Japan andRussiawill conduct space debris cleanup experiment together.C. These kinds of demonstrations have never been done before.D. The demonstration mission will be divided into three phases.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。

Given that Neil Armstrong wanted to take a football to the Moon, we could even say that it is also the most popular sport out of this world! The history of the game goes back over two thousand years to Ancient China. It was then known as cuju (kick ball), a game using a ball of animal skins with hair inside. Goals were hung in the air. Football as we know it today started inGreat Britain, where the game was given new rules.That football is such a simple game to play is perhaps the basis of its popularity. It is also a game that is very cheap to play. You don’t need expensive equipment; even the ball doesn’t have to cost much money. All over the world you can see kids playing to their hearts’ content with a ball made of plastic bags.Another factor behind football’s global popularity is the creativity and excitement on the field. It is fun enough to attract millions of people. You do not have to be a fan to recognize the skill of professional players or to feel the excitement of a game ending with a surprising twist.What’s more, football has become one of the best ways for people to communicate: it does not require words, but everyone understands it. It breaks down walls and brings people together on and off the field.“Some people believe football is a matter of life and death, ...” said Bill Shankly, the famous footballer and manager. “I can tell you with certainty it is much, much more important than that.” This might sound funny, but one only has to think about the Earth to realize that our planet is shaped like a football.4. What can we know from paragraph one?A. Some people like to play football on the Moon.B. The game called cuju was given new rules today.C. Cuju is different from football as we know it today.D. Many people like playing a ball made of plastic bags.5. According to the author, there are ________ reasons why football became so popular in the world.A. 3B. 4C. 5D. 66. What can be inferred from the last paragraph?A. Football is round.B. Football is more than just a sport.C. Our planet is shaped like a football.D. What Bill Shankly said sounds funny.7. What’s the author’s purpose in writing the passage?A. To talk about the history of football.B. To express his/her love of football.C. To explain why football is such a popular game.D. To prove that he/she is a professional football fan.CWhen you walk with a backpack, do you know how the things inside move from side to side? Now scientists havefigured out how to tap into that movement to produce electricity.Picture a pendulum (摆锤) fixed to a backpack frame and stabilized with springs on either side. The pack’s weight is attached to the pendulum, so the pendulum swings side to side as you walk.Then a machine is driven by that swinging movement, and spits out electrical current to charge a battery.Volunteers carried the pack while walking on a running machine and wore masks to measure the flow of O2and CO2. Walking with the slightly swinging 20-pound load, the device (设备) did not significantly affect the volunteers’ metabolic (新陈代谢的) rate compared to when they carried the same weight fixed in place. In fact, the energy-harvesting pack reduced the forces of acceleration they’d feel in a regular pack, which might mean greater comfort for a long hike. And the device did produce a steady trickle (涓流) of electricity. If you up the load to 45 pounds, the swing of the pack could fully charge a smart phone only after 12 hours. The details are in the journal Royal Society Open Science.The device produces electricity from human movement and has been identified as a workable solution to providing a renewable energy source for portable electronic devices. It is particularly useful for those who work in remote areas, as these people often carry a lot of weight in a backpack for their exploration.But here’s a realconundrum: the energy-harvesting device currently weighs five pounds. The researchers saythat’s about four pounds too many to be a smart alternative to batteries. So they hope that more research lets them lighten the load, to ensure the pack charges you up without weighing you down.8. What does Paragraph 2 mainly talk about?A. How the device works.B. What the device looks like.C. Who the device is designed for.D. Why scientists designed the device.9. Which of the following describes the device?A. It greatly affected the volunteers metabolic rate.B. It harvested energy as the volunteers walk.C. It failed to produce steady electricity.D. It was useless for a long walk.10. What does the underlined word “conundrum” in the last paragraph mean?A. Problem.B. Method.C. Bond.D. Decision.11. What will the researchers try to do next?A. Increase the charging speed of their device.B. Find smarter alternatives to batteries.C. Reduce the weight of their device.D. Put their device on the market.DThe beach may seem like an inviting place to run on a cool summer morning, but is running on the sand good for your body? It can be, but it’s important to be aware of the challenges that some beach runners experience before you get ready.Running on the beach can be a good thing. It’s certainly different from running on a track or a pavement. For starters, sand can be a challenge because it has an uneven (不平坦的) surface. As you push off, you’re going to lose some of your push as the sand moves. So, you’re not going to be able to push yourself forward as you would on a track or a pavement. But this unevenness has anupside: It gives your body an extra workout, forcing you to exercise muscles that don’t get as much use during runs on firm surfaces. For example, your feet, ankles and lower back might feel sorer and more tired than usual after a beach run just because the surface is constantly moving and changing step to step.You also might feel sore afterward because beaches tend to slope (倾斜) down to the water. If you’re going for a long run on the beach, you might notice that one side of your body might feel sorer because you’re putting more pressure on it due to the slope.Some beach runners prefer to run barefoot — not wearing anything on feet. However, if you’re not used to barefoot running, start slowly and don’t run long distances at first. That’s because running barefoot uses more different muscles than running with shoes does, and it’s important to strengthen these muscles and adapt your feet. If you want to run barefoot and as long as you run carefully enough into it, go for it!Running on the sand can be a smart choice for you, because running on softer ground surfaces can reduce muscle damage.12. Why is it difficult to run on the beach for starters?A. The soft surface makes people fall over easily.B. People need to run carefully on its smooth surface.C. Running on its uneven surface takes much effort.D. It’s hard to keep one’s balance on its hard surface.13. Which of the following best explains “upside” underlined in Paragraph 2?A. Advantage.B. Reason.C. Character.D. Challenge.14. What’s the author’s attitude to barefoot running?A. Critical.B. Supportive.C. Doubtful.D. Uncaring.15. The passage can probably be found in ______.A. A primary school textbookB. A tourist guideC. A sports magazineD. A scientific report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。

In this instance, it was Samantha Bee, stating her opposition to childhood vaccinations humorously. “Who are you going to believe?” she asked. “Leading authorities on medical science, or 800 comments on your cousin’s Facebook page?”Joking about science can have serious effects, according to studies by communication scholars. Accordingly, since 2013, Paul, a psychological professor, has conducted studies of how satire (讥讽) can influence people’s beliefs about science, which have shown that if you want to interest people in science and shape their views on hot-button science issues, satirical humor can work better.Many Americans pay little attention to science. Even people who regularly watch TV news receive only scraps of science information in their media diet, because mainstream media outlets devote so little airtime to the subject. On top of that, some Americans may regard science as inaccessible.Yet satirical humor can reach viewers who would never watch NOVA or read — well, National Geographic. Millions of people watch late-night television programs live, and videos of these shows get millions of views on streaming services. In 2016, a vote conducted by the University of Delaware Center indicated that nearly one in 10 said they learned about science from late-night television shows.Late-night hosts may occasionally poke fun at scientists. More often, however, the hosts promote a positive image of science. By making science entertaining to audience with little knowledge of the topic, late-night television could spark science engagement. Furthermore, the researchers concluded that satirical shows had the biggest impact among the least educated viewers, thus helping to narrow a gap in attention to science. Though late-night satirical humor can boost science interest and awareness, it has its limits. Science is complex, and conveying that complexity in a few minutes while telling jokes can be a challenge.4. What does Paul’s studies of joking about science indicate?A. It may do serious damage to science.B. It can effectively popularize science.C. It totally changes people’s attitude to science.D. It will shift people’s attention from entertainment to science.5. Why do TV watchers receive a little science information?A. Because they enjoy watching entertainments.B. Because science is not easy to come up with.C. Because they find no interest in science issues.D. Because science is scarcely seen on mainstream media.6. What do we know about the late-night shows involving science?A. The hosts get used to playing tricks on scientists.B. The hosts’ aim is to build a positive image of science.C. Education gap can be bridged through late-night shows.D. Science participation can be promoted among their viewers.7. What’s the author’s attitude towards combining science with satire?A. Critical.B. Objective.C. Positive.D. Negative.CEarthquakes are a natural disaster—except when they're man-made. The oil and gas industry has forcefully used the technique known as hydraulic fracturing (水力压裂法) to destroy sub-surface rock and liberate the oil and gas hiding there. But the process results in large amounts of chemical-filled waste water. Horizontal drilling (水平钻孔) for oil can also produce large amount of natural, unwanted salt water. The industry deals with this waste water by pumping it into deep wells.On Monday, the US Geological Survey published for the first time an earthquake disaster map covering both natural and “induced” quakes. The map and a report show that parts of the central United States now face a ground-shaking disaster equal to the famously unstable terrain (不稳定地形) of California.Some 7 million people live in places easily attacked by these man-made quakes, the USGS said The list of places at highest risk of man-made earthquakes includes Oklahoma, Kansas, Texas, Arkansas, Colorado, New Mexico, Ohio and Alabama. Most of these earthquakes are ly small, in the range of magnitude (震级) 3, but some have been more powerful, including a magnitude 5.6 earthquake in 2011 in Oklahoma that was connected to waste water filling.Scientists said they do not know ifthere is an upper limit on the magnitude of man-made earthquakes; this is an area of active research Oklahoma has had prehistoric earthquakes as powerful as magnitude 7.It's not immediately clear whether this new research will change industry practices, or even whether it will surprise anyone in the areas of newly supposed danger. In Oklahoma, for example, the natural rate of earthquakes is only one or two a year, but there have been hundreds since hydraulic fracturing and horizontal drilling, with the waste water filling, became common in the last ten years.8. What kind of human activities can cause earthquakes?A. The man-made produced waste water in the factories.B. The process of digging deep wells in those poor areas.C. The advanced techniques used to deal with waste water.D. The oil or gas industry's work connected with the earth.9. What does the underlined word “induced” in paragraph 2 mean?A. Man-made.B. Reduced.C. Newly-built.D. Controlled.10. How much magnitude can man-made earthquakes reach?A. It's been said as small as magnitude 3.B. It has been said as high as magnitude 7.C. It's being studied without a final conclusion.D. It has risen by an average of magnitude 5. 6.11. What is the best title for the text?A. Natural Earthquakes in America Are Disappearing NowB. 7 Million Americans at Risk of Man-Made EarthquakesC. Time for Oil and Gas Industry Change Their Working PracticeD. More Often Earthquakes as Powerful as Magnitude 7 in AmericaDIn a world simultaneously on fire and underwater thanks to climate change, scientists have announced some good news: Several important tuna (金枪鱼) species have stepped back from the edge of extinction.The unexpectedly fast recovery speaks to the success of efforts over the past decade to end overfishing. But tuna are not the only species scientists are discussing at the 2021 World Conservation Congress in Marseille, France, which is organized by the International Union for Conservation of Nature (IUCN). Researchers caution that manyother marine species remainimperiled. For instance, more than a third of the world's sharks remain threatened with extinction due to overfishing, habitat loss, and climate change.“I think the good news is that sustainable fisheries are possible,” says Beth Polidoro, a marine biologist at Arizona State University. “We can eat fish in a proper way and without driving the population to the point where it is on the road to collapse or extinction."At the same time, she warned that the changes in status should not be an reason to catch as many fish as we want.The IUCN, which ranks the world's most endangered species on its Red List of Threatened Species and is backed by 16,000 experts across the globe, also announced at the meeting that some animals are moving in the other direction, onto the Red List. One notable example is the Komodo dragon, an island-living lizard at particular risk from climate change.For the better part of two decades, Polidoro has been part of a specialist group tasked with assessing the statuses of more than 60 species of tuna and billfishes for the IUCN.Her team announced its first comprehensive findings in 2011, mentioning that a number of commercially fished tuna species were dangerously close to disappearing.According to the new data, the Atlantic bluefin tuna (Thunnus thynnus), once listed as endangered, now qualifies for a status of least concern. As does the yellowfin tuna (Thunnus albacares) and albacore tuna (Thunnus alalunga), which were both considered near-threatened the last time they were assessed.12. What does the underlined word “imperiled” in paragraph 2 mean?A. EndangeredB. ConservedC. ExtinctD. Safe13. What can we infer from Polidoro's words?A. Too many fish are being eaten by human beings.B. Eating fish does not necessarily lead to its extinction.C. Fish species are on the edge of dying out if no action is taken.D. The situation of underwater species are changing for the better.14. Which of following statement is true according to the passage?A. Some Tuna species are wiped out by overfishing.B. Tuna are ranked as the world's most endangered species.C. Climate change poses a threat to most species in water and on land.D. Three tuna species have been saved from extinction according to the data.15. What's the main idea of the passage?A. Some tuna species are reported endangered recently.B. IUCN has helped saved a great many marine species.C. Improvement has been made in saving marine species.D.

B.A traveler's journal.C.A news report.D.A trip guide.BIf you have ever tried to catch a resting butterfly, you know it is surprisingly difficult. A new study helps explain why.Previous research had suggested that a butterfly's overhead wing clap forces the insect forward. Researchers thought the wing clap likely formed a pocket of air that shoots out like a jet, but no one had tested that until now.To understand their flight, they placed six butterflies one at a time inside a wind tunnel which was filled with smoke and then used a laser to light up the smoke just behind the butterfly. Four high-speed cameras were placed in the tunnel to take photos of the movement of the butterfly and the-smoke as the butterfly was taking off. This let the researchers create a 3D picture of that air movement as the insect flapped its wings.They observed a total of 25 takeoffs by six butterflies. Each included up to three wing beats after takeoff.The butterflies proved more likely to clap their wings together during the first few wing beats than later in flight.The photos show that forces created by the wings give rise to a flight path. The butterflies rise as their wings move down and shoot forward as their wings move up. A wing clap on takeoff, paired with a quick tum, allowed the butterflies to fly away quickly. They also noticed the wings formed an air pocket just before clapping and that the wings' flexibility and this pocket improved the jet force created by the clap.“The study is exciting,” says Ayodeji Bode-Oke, a mechanical engineer in Charlottesville. That means “we have solved the longtime puzzle about how butterflies fly, and it proves nothing is impossible on the road of scientific research. I can't wait to learn about how the study might inform designs for small aerial vehicles.”4. Why was laser used in the experiment?A. To frighten the butterflies into lying.B. To help researchers observe the butterflies.C. To help take clear photos of air movement.D. To guide the butterflies through the smoke.5. What is the finding of the research-according to paragraph 5?A. Butterflies fly forward as wings move down.B. An air pocket forms after butterflies clap wings.C. Butterflies beat wings three times before taking off.D. Upward wing movements help butterflies fly forward.6. According to the writer, the finding of the research can be used for .A. helping catch a resting butterfly more easilyB. helping do research on other butterfly-like insectsC. helping provide inspiration for making small flying vehiclesD. helping widen the applications of small flying vehicle7. What can be the best title for the text?A. Why Can Butterflies Fly Like a Jet?B. How Can Butterflies Make Wing Claps?C. How Can Butterflies Make Quick Tums?D. Why Can Butterflies Run Away Quickly?CWith their tiny brains and excellent ability to memorize nectar locations, honeybees are a favorite model organism for studying learning and memory. 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, taskingthem 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.”8. 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.9. 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.10. What is Andre Fiala’s attitude towards the new results?A. Doubtful.B. Favorable.C. Intolerant.D. Unclear.11. 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 CommunicationDWhen you walk on a sandy beach, it takes more energy than striding down a sidewalk — because the weight of your body pushes into the sand. Turns out, the same thing is true for vehicles driving on roads. The weight of the vehicles creates a very shallow indentation (凹陷) in the pavement (路面) — and it makes it such that it’s continuously driving up a very shallow hill.Jeremy Gregory, a sustainability scientist at M.I.T. and histeam modeled how much energy could be saved — and green-house gases avoided — by simply stiffening (硬化) the nation’s roads and highways. And they found that stiffening 10 percent of the nation’s roads every year could prevent 440 megatons of carbon dioxide equivalent emissions over the next five decades — enough to offset half a percent of projected transportation sector emissions over that time period. To put those emissions savings into context — that amount is equivalent tohow much CO2 you’d spare the planet by keeping a billion barrels of oil in the ground — or by growing seven billion trees — for a decade.The results are in the Transportation Research Record.As for how to stiffen roads? Gregory says you could mix small amounts of synthetic fibers orcarbon nanotubes into paving materials. Or you could pave with cement-based concrete, which is stiffer than asphalt (沥青).This system could also be a way to shave carbon emissions without some of the usual hurdles. Usually, when it comes to reducing emissions in the transportation sector, you’re talking about changing policies related to vehicles and also driver behavior, which involves millions and millions of people — as opposed to changing the way we design and maintain our pavements. That’s just on the order of thousands of people who are working in transportation agencies. And when it comes to retrofitting (翻新) our streets and highways —those agencies are where the rubber meets the road.12. Why does the author mention “walk on a sandy beach” in paragraph 1?A. To present a fact.B. To make a contrast.C. To explain a rule.D. To share an experience.13. What suggestion does the author give to reduce CO2 emissions?A. Hardening the road.B. Keeping oil in the ground.C. Growing trees for decades.D. Improving the transportation.14. What is the advantage of this suggestion?A. Gaining more support.B. Consuming less money.C. Involving more people.D. Facing fewer usual obstacles.15. What does the underlined part mean in the last paragraph?A.Those agencies are likely to make more rules.B. Those agencies will change some related policies.C. Those agenciesmight put more rubber tires on the roads.D. Those agencies will play a key role in making this happen.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。
