Bui now researchers are finding that video games can actually change us for the better and improve both our body and mind.Games can help to develop physical skills. Pre-school children who played interactive games have been shown to have improved motor skills, for example they can kick, catch and throw a ball better than children who don’t play video games. A study found that those who played video games were 27 percent faster and made 37 percent fewer errors than those who didn't.Games also benefit a variety of brain functions, including decision-making. People who play action-based games make decisions 25 percent faster than others, according to one study. It was also found that the best gamers can make choices and act on them up to six times a second, four times faster than most people. In another study by researchers from the University of Rochester in New York, experienced gamers were shown to be able to pay attention to more than six things at once without getting confused, compared with the four that most people can normally keep in mind.There is also evidence that gaming can help with psychological problems. At the University of Auckland in New Zealand, researchers asked 94 young people diagnosed with depression to play a 3D fantasy game called SPARX and in many cases, the game reduced symptoms of depression more than conventional treatment.4. In what way playing video games benefits very young children?A. Muscle control.B. Social interaction.C. Decision-making.D. The ability to focus.5. Which type of video game improves the decision-making speed?A. Interactive games.B. Action-based games.C. 3D fantasy games.D. Violent games.6. What is the authors attitude to video games?A. Indifferent.B. Objective.C. Worried.D. Critical.7. What is the text mainly about?A. The effects of different types of video games.B. The negative effects of playing video games.C. The beneficial effects of playing video games.D. The effects of games on people's behavior.CThe far side of the moonis a strange and wild region, quite different from the familiar and mostly smooth facewe see nightly from our planet. Soon this rough space will have even stranger features: it will be crowded with radio telescopes.Astronomers are planning to make the moon's distant side our newest and best window on the cosmic(宇宙的) dark ages, a mysterious era hiding early marks of stars and galaxies. Our universe was not always filled with stars. About 380,000 years after the big bang, the universe cooled, and the first atoms of hydrogen formed. Gigantic hydrogen clouds soon filled the universe. But for a few hundred million years, everything remained dark, without stars. Then came the cosmic dawn: the first stars flickered, galaxies came into existence and slowly the universe's large­scale structure took shape.The seeds of this structure must have been present in the dark­age hydrogen clouds, but the era has been impossible toprobeusing optical(光学的) telescopes—there was no light. And although this hydrogen produced long­wavelength(or low­frequency) radio emissions,radio telescopes on Earth have found it nearly impossible to detect them. Our atmosphere either blocks or disturbs these faint signals; those that get through are drowned out by humanity's radio noise.Scientists have dreamed for decades of studying the cosmic dark ages from the moon's far side. Now multiple space agencies plan lunar missions carrying radio­wave­detecting instruments—some within the next three years—and astronomers' dreams are set to become reality.“If I were to design an ideal place to do low­frequency radio astronomy, I would have to build the moon,”says astrophysicist Jack Burns of the University of Colorado Boulder. “We are just now finally getting to the place where we're actually going to be putting these telescopes down on the moon in the next few years.”8. What's the purpose of building radio telescopes on the moon?A To research the big bang. B. To discover unknown stars.C. To study the cosmic dark ages.D. To observe the far side of the moon.9. What does the underlined word “probe” in Paragraph 3 possibly mean?A. Explore.B. Evaluate.C. Produce.D. Predict.10. Hydrogen radio emissions can't be detected on Earth because ________．A. there was no light in the dark agesB. they cannot possibly get through our atmosphereC. gigantic hydrogen clouds no longer fill the universeD. radio signals on Earth cause too much interference11. What can we infer from theunderlined sentence in the last paragraph?A. Scientists have to rebuild the moon.B. We will finally get to the moon's distant side.C. The moon is a perfect place to set up radio telescopes.D. A favorable research environment will be found on the moon.DIn a recent survey of 2000 Americans, housecleaning was shown to have some mood-boosting effects — but that doesn't mean everybody is willing to do it.The majority of respondents (受访者) said cleaning gave them a sense of accomplishment (65%) and helped them clear their mind (63%). Half of these adults said they are most often motivated to clean when they're happy. In fact, 63% of those surveyed find the experience of cleaning to be relaxing - even more so than getting fresh air (61%).But that's not the only reason people clean. A big 70% admitted that tidying their home was a way of putting off having to do other things, with the average procrastinator (拖延者) using that trick four times a week. The survey showed that 86% of respondents do feel on top of their housework, but the last deep clean of their kitchen happened over a week and a half ago. That's no surprise because the kitchen is most terrible of all.Conducted by OnePoll on behalf of DishFish, the survey investigated people's attitudes toward dirty dishes and how they get through tricky task. More than two-thirds of people (69%) let their dishes pile up between washings with 20% saying “always” letting them be placed in the sink, which left them feeling stressed. More than any other room, the kitchen was rated as “very difficult” to cope with. And most people enjoy cleaning their toilet or taking out the garbage more than washing dishes by hand.How do they get through it? 66% listen to music while they clean. 72% have a best-loved song that they sounded while tidying up their home, with “Uptown Funk,”“Read All About It” and “Work” being the three favorite tunes on America's cleaning playlist.12. What is the result of the survey?A. Housecleaning may contribute to a good mood to some extent.B. Housecleaning may strengthen people's willingness to volunteer.C. Housecleaning may cause anxiety and concern for some people.D. Housecleaning may improve people's motivation to other housework.13. What is the top reason why people undertake housecleaning?A. They can entertain themselves.B. They can take in fresh air.C. They get a sense of achievement.D. They can delay other things.14. What are respondents' attitudes to dirty dishes?A. Many would rather wash dishes than throw out the rubbish.B. Half are under pressure with dirty dishes lying in the sink.C. A quarter will let dirty dishes pile up after their meals.D. Most prefer cleaning their toiletto washing dishes by hand.15. What column does the text belong to?A. Feature Story.B. Family Life.C. Scientific Hotspot.D. Finance Focus.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

And thishas great consequences on our health, our job performance, our relationships and our happiness. What is needed, she ly declares, is nothing short of a sleep revolution. Only by renewing our relationship with sleep can we take back control of our lives.In her bestseller Thrive, Arianna wrote about our need to redefine success through wellbeing, wisdom, wonder, and giving. Her discussion of the importance of sleep as a gateway to this more fulfilling way of living struck such a powerful chord (弦) that she realized the mystery and transformative power of sleep called for a fuller investigation (调查).The result is a scientifically sweeping and personal exploration of sleep from all angles, from the history of sleep, to the role of dreams in our lives, to the consequences of sleep deprivation (剥夺), and the new golden age of sleep science that is showing the vital role sleep plays in our every waking moment and every aspect of our health — from weight gain, diabetes, and heart disease to cancer and Alzheimer’s.In The Sleep Revolution, Arianna shows how our cultural removal of sleep as time wasted damages our health and our decision-making and our work lives and shortens our personal lives. She explores all the latest science on what exactly is going on while we sleep and dream. She decides the dangerous sleeping pill industry, and all the ways of our addiction to technology disturb our sleep. She also offers a range of recommendations and tips from leading scientists on how we can get better and more restorative sleep.In today’s fast-paced, always-connected and sleep-deprived world, our need for a good night’s sleep is more important than ever. The Sleep Revolution both sounds the alarm on our worldwide sleep crisis and provides a detailed road map to the great sleep awakening that can help transform our lives, our communities, and our world.4. What is the first paragraph mainly about?A. The importance of sleep.B. The necessity of improving sleep.C. The way to improve our sleep.D. The effect of sleep on health.5. What can be inferred about Arianna’s attitude to success?A. She thinks good sleep is more important.B. She doesn’t think much of becoming successful.C. She thinks it wrong to sacrifice health to success.D. She is concerned about the nature of success.6. What can be said about Arianna’s investigation?A. It is really of great value.B. It is scientific and historical.C. It costs Arianna’s sleep in practice.D. It covers all necessary aspects scientifically,7. What influence does TheSleep Revolution have on society?A. It helps to slow down the pace of modern life.B. It warns people against taking sleeping pills.C. It warns the harm of inadequate sleep of people.D. It helps to stress the value of sleep to success.CPaper is one of our oldest, simplest and most important inventions. But it also presents a danger to the world in two important ways. First, the making of paper requires the loss of many millions of trees each year. And worldwide use of paper is expected to double in the next 40 years. Clearly, the planet cannot stand such a high rate of forest loss. The second great problem with paper is what happens once it is no longer useful. A large amount of wastepaper ends up in landfills, where it can produce harmful gases and finally contribute to global climate change.One simple solution can greatly reduce both of these problems: paper recycling. Instead of cutting down trees, recycle existing paper to feed the paper-making process.Paper is mainly made from cellulose (纤维素)，which can be used repeatedly in papermaking. Unfortunately, it also means that paper waste takes a surprisingly long time to break down in landfills. So far, trees are the only source(来源) of cellulose that can fill the great demand for paper products. Therefore, recycling paper is simply one of the best ways to save trees. Thanks to advances in processing, recycled paper need not be the dark-color1 edstuff many of us are familiar with. It now can offer the same print performance as non-recycled paper.Effective recycling requires a continuous effort from everyone at all levels of society. The way to begin is with education and understanding. Once enough people realize the need for recycling, more effective recycling systems can be developed.The need is real. The massive loss of trees affects everybody on earth. Everyone should do their part torecycle paper and encourage government and industry to do the same. The world will be a better place for it!8. What can we infer from the text?A. The use of recycled paper will double in 40 years.B. Recycling paper helps relieve global climate change.C. Wastepaper can easily break down in landfills.D. There are not enough landfills for wastepaper.9. What makes recycled paper more acceptable?A. The great demand of trees.B. The low processing cost.C. Its dark-color1 ed feature.D. Its improved print performance.10. What does the author propose?A. Punishing the act of cutting trees.B. Recycling paper.C. Improving recycling system.D. Promoting paper industry.11. How is the text mainly developed?A. By analyzing causes and effects.B. By offering research plans and data.C. By discussing problems and solutions.D. By comparing strengths and weaknesses.DAmerican football was the fastest-growing sport for US young players last year, according to a survey sponsored by the sport's governing body.But it was the game's no tackle variety that showed the biggest increase－a finding that may reflect concerns about injury. In American football, a tackle (抢断球) refers to an attempt to stop an opponent by forcing them to the ground.The number of participants in football grew in 2015 while most other sport, except baseball, posted a decline, USA Football said on Monday, citing(引用) the findings of a survey of 30,000 children and teenagers.Participation in flag football (a no-tackle type of football) increased by 8.7 percent among children aged 6 to 14, while tackle football rose by 1.9 percent. For that age group, the only other sport that grew was baseball, with a 3. 3 percent increase.In the 15-to-18 age group, flag football rose by 10. 5 percent, while tackle grew by 2.5 percent.Basketball was the third, with a 1. 1 percent increase. Participation in all other sports declined.Tom Farrey, executive director of the Aspen Institute's Sports & Society Program, said he was surprised that flag football participation rose so much.“The trend suggests that parents aremarching to the beat of a different drummer, in pursuing flagas an alternative for their kids," he said.The findings come at a time of increasing concern about the risk associated with youth sports, particularly hockey (曲棍球) and football, where medical researchers have warned about the risk of concussions (damagesto the brain caused by violent blows to the head) and death linked to brain injury.USA Football, anIndianapolis,Indianabased nonprofit funded in part by the National Football League, believed that the increases resulted from better safety and health education."Football participation increases, even modest increases, may signal that programs such as our Heads Up Football program and practice guidelines are making a positive difference," said Scot Hallenbeck, USA Football chief executive, in a statement.Robert Cantu, aBostonUniversityneurosurgery professor and investigator at the school's chronic Traumatic Encephalopathy (CTE) Center said the increase in fag football participation signaled that more parents were directing children to a safe alternative12. What can we learn about the two age groups?A. Flag football grew the fastest in the 6-to-18 group.B. Tackle football grew he fastest in the 6-to-14 group.C. Participation in baseball declined the most in both groupsD. Participation in tackle football increased the most in both groups.13. The underlined part probably means ________.A working at a different paceB. behaving in a different wayC. ignoring the major differencesD. trying to accept different opinions14. The popularity of flag football is inked with the fact thatA. its rules have been adapted for young playersB. it receives more funds than other varietiesC. tackle football is an old-fashioned gameD. experts worry about children's safety15. What is the cause of football growth according to USA Football?A. Their safety programs are successful.B. More children show interest in the game.C. Football is less likely to cause concussions.D. There are different types of football to choose from.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

2021届重庆育才学校高三英语一模试题及答案解析第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项ASome of the world’s most talented musicians have played concerts atLincolnCenter. On September 10, the center hosted a unique class of star musicians: kids and teens. The young players are part of the World Peace Orchestra, or WPO. The group held its first Music for Peace concert inNew York City, with 134 students from more than 60 countries taking part. Musicians were chosen from all over the world.The World Peace Orchestra began in 2013. The nonprofit group brings kids together using the common language of music. To be considered for the orchestra, students first had to be recommended by their teachers and then audition online for a group of judges. Once chosen, professional musicians and teachers then worked with the players to improve their skills.Some of the young musicians played classical instruments, such as violins and flutes. Others played instruments unique to their home country. For example, Amold Mugo, 16, fromKenya, played an instrument called the djembe. The drum is originally fromWest Africa. Mugo said he was shocked when he learned he was chosen for the orchestra. “I can’t express how I felt. I was rolling on the floor. It’s a once in a lifetime opportunity,” he said.Adomas Hendrixson, 13, fromLithuania, played piano for the WPO. Before theNew York Cityperformance, Hendrixson talked about what he hoped to take away from the event. “Fun and joy-- people smiling and clapping,” he said.“This is one of the only times in your life this could happen and I'm very excited.”Mugo says his favorite part of the WPO is making new friends from around the world. “I hope when I go home, I just take a little bit of every friend that I made here-- Brazil, Portugal, Queens,” Mugo said, “I hope that I take part of their culture home with me so I understand them more.”1. Who is most likely to have played for the WPO according to this passage?A. Li Ming, 16, a student fromChina.B. Daniel, 44, a judge fromAmerica.C. Edward, 21, a clerk fromAustralia.D. Catherine, 32, a teacher fromEngland.2. We can learn from the last paragraph that Mugo ________.A.performed best for the WPO.B. has learned some foreign culture.C. was eager to be chosen for a second time.D. received a great award for his performance.3. What would be the best title for this passage?A. Kids were good at playing music.B. Mugo liked making foreign friends.C. Concerts were played atLincolncentre.D. Young musicians played for peace.BI don’t think I can recall a time whenI wasn’t aware of the beauty of the ocean. Growing up inAustralia, I had the good fortune of having the sea at my side. The first time I went toHalfmoonBay,I suddenly had the feeling of not being able to feel the ground with my feet anymore.For my 10th birthday, my sister and I were taken out to theGreat Barrier Reef. There were fish in different color1 s, caves and layers of coral. They made such an impression on me. When I learned that only one percent ofAustralia’sCoral Seawas protected, I was shocked. Australian marine (海洋的) life is particularly important because the reefs have more marine species than any other country on earth. But sadly, only 45% of the world’s reefs are considered healthy.This statistic is depressing, so it’s important for usto do everything to protect them. The hope that theCoral Searemains a complete ecosystem has led me to take action. I’ve become involved with the Protect Our Coral Sea activity, which aims to create the largest marine park in the world. It would serve as a place where the ocean’s species will all have a safe place forever.Together, Angus and I created a little video and we hope it will inspire people to be part of the movement. Angus also shares many beautiful childhood memories of the ocean as a young boy, who grew up sailing, admiring the beauty of the ocean, and trying to find the secrets of ocean species.4. What can we learn about the author from the underlined sentence inPara. 1?A. He seldom went surfing at the sea.B. He forgot his experiences about the ocean.C. He never went back to his hometown.D. He had a wonderful impression ofHalfmoonBay.5. What is Australian marine life like according to the second paragraph?A. It is escaping from theCoral Seagradually.B. It depends on reefs for living greatly.C. It may be faced with danger.D. It is protected better than that in other oceans.6. What’s the purpose of The Protect Our Coral Sea activity?A. It is intended to contribute to a complete ecosystem.B. It is intended to prevent more marine species being endangered.C. It is intended to set up a large nature reserve for reefs.D. It is intended to raise more teenagers’ environmental awareness.7. Why do Angus and the author create a little video?A. To urge more people to take action toprotect the marine species.B. To inspire more people to explore the secret of the ocean.C. To share their childhood experiences about the ocean.D. To bring back to people their memory of ocean species.C“They’re harming your brain.” “They’re ruining your eyes.” “They’re turning you into a violent person.” The words said publicly against video games are so common, but are these worries founded on actual science? Countless studies have offered different opinions on whether video games are bad for you. We’ve rounded up the most notable reports and studies below, so you can weigh up the evidence for yourself.In 2013,psychologist(心理学家) Simone Kuhn studied the influences of spending long hours on video games on the brains of young adults and found that several areas became bigger than before. These areas are connected with highercognitive functions(认知功能), memory formation andfinemotor(精细运动) function.Last year, psychologists said that video game players who favour violent games are more likely to be violent when offline. Dr. Mark Appelbaum of the American Psychological Association said that there was a relation between violent video game use and increases in violent behaviour.Dr. Daphne Bavelier is an expert in the field of Brain & Cognitive Sciences. Bavelier presented the audience with a colour-word test, where non-gamers are easily puzzled by the test, and those who spend long periods playing on their computers are more likely to pass the test with flying colours.“Actually, those video game players have many other advantages in terms of attention,” said Bavelier, “and one part of attention which is also improved for the better is our ability to follow the movements of objects.”“So, in a sense, when we think about the influence of video games on the brain, it’s very similar to the influence of wine on the health. There are some very poor uses of wine. There are some very poor uses of video games. But when drunk in reasonable amounts, and at the right age, wine can be very good for health,” said Bavelier.8. What can be learned from Simone Kuhn’s study？A. Video games make you happier.B. Video games make your brain grow.C. Video games play a key role in memory.D. Video games teach you how to learn fast.9. What was Dr. Mark Appelbaum’s attitude towards video games？A. He was against them.B. He was hopeful of them.C.He was in favour of them.D. He was uncertain about them.10. Which of the following may Dr. Daphne Bavelier agree with？A. Video games fix attention problems.B. Video games make kids do well in exams.C. Video games encourage violent behaviour.D. Video games help increase colour knowledge.11. Why are the uses of wine mentioned in the last paragraph？A. To remind people to avoid video games.B. To show the disadvantages of video games.C. To help people learn more about video games.D.To ask people to make good use of video games.DPhotographer Rebecca Douglas has always been fascinated by the night sky. Her love for stars has taken theU.K.resident on “star walking” trips toIcelandand into theArctic, where she steps out onto darkened trails to capture twinkling stars and glowing planets in her images.Hiking at night isn’t uncommon. Plenty of people hike after dark to get to campsites or watch the sunrise from a mountaintop. Star walking goes a step further by blending hiking with stargazing. Rather than heading to an observatory or setting up a telescope in your backyard,star walking takes you on a brief journey to look at the stars from different viewpoints.Whether you’re in the mountainside or by the lake with stars reflecting on the water, star walking is often much more dynamic than traditional stargazing.What’s more, star walking is good for you. There are plenty of studies that show the health benefits of being in nature. Spending at least two hours a week outdoors, particularly while engaging in what involves “effortless attention”, can decrease blood pressure, heart rate, and stress levels.So how does an aspiring star walker get started? It doesn’t take much more than a sturdy pair of boots.While telescopes and binoculars obviously have their uses, people are encouraged to start with naked-eye stargazing. Using only the eyes allows one to get lost in the infinite expanse of space and lets the mind go.It is advised that one read up on the night sky before heading out. Free mobile apps, such as Star Walk 2, can help identify celestial bodies（天体）and are easy to use—simply point your phone at the sky to reveal a map. Websites like Sky & Telescope and NASA’s Space Place cover the basics, have in-depth explanations on stars, and offer advice on equipment. Space Place posts monthly skywatching updates, so you can plan outings around events such as meteor showers.In the United States, national parks are great options for inexperienced night hikers. Many offer guided outings that explain the importance of protecting night skies. Those with a good number of walks under their belt may want to try GlacierNational Park in Montana.If national parks and other dark-sky designated areas are out of range, check local astronomy clubs and observatories for guided sessions. Sites like the International Astronomical Union are useful for finding resources by area.At the end of the day, the best advice is to take it slow and enjoy the journey.“With all of the chaos（混乱）that’s happening around us, the one constant has been the night sky,” explains Douglas, who hasbeen exploring popular places nearby, long after the crowds have gone home for the day. “Walking is quite a mindful way of looking up and being reminded that, although everything feels so different, some things are still the same.”12. According to the passage, star walking refers to ________.A. going to an observatoryB. looking at stars in mountainsC. combining hiking and stargazingD. setting up a telescope in the backyard13. One of the reasons why people go on a star walking is that _______.A. it’s easier to identify celestial bodiesB. it is good for physical and mental healthC. they can enjoy the journey without crowdsD. they can raise awareness of protecting night skies14. According to the passage, a star walking beginner is advised to _______.A. prepare a pair of strong bootsB. start by observing with telescopesC. join an astronomy club or an observatoryD. find guided outings with the help of mobile apps15. The main purpose of the passage is to ________.A. excite people’s interest in star walkingB. recommend some places for star walkingC. explain the health benefits of star walkingD. introduce the preparations for star walking第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。
