2021年诸城市第一中学高中部高三语文模拟试题及答案
2021年诸城市第一中学高中部高三语文模拟试题及答案一、现代文阅读(36分)(一)现代文阅读I(9分)阅读下面的文字,完成后面小题。
马的历史,非常悠久。
甲骨文中就有马的形象。
据史书记载,商周时贵族出行多乘马车或骑马。
贵族死后,作为陪葬的马匹也占据着一席之地。
霍去病墓的石雕群,唐太宗的昭陵六骏,无不显示出统治者对马的重视。
也正是马在古时的特殊地位和作用,以及帝王对良马的喜爱,在客观上促进了“马艺术”发展。
汉武帝不惜重金和发动战争来换取汗血宝马。
马成为汉代绘画和雕塑中经常出现的题材和内容。
唐太宗属马,也特别爱马。
在我国石雕艺术史上,汉代霍去病墓石雕群、唐太宗的昭陵六骏树起了意象造型与写实造型的艺术风格几乎不可逾越的高峰。
同一表现对象的马在各朝艺术家的艺术创作中呈现出各式面貌,虽然霍去病墓石雕群与昭陵六骏这两组马的石雕艺术品是在不同时代的特殊风格下成就了它们各自独特的艺术面貌,但它们之间又有着千丝万缕的联系和相通之处。
一是意象造型与写实造型的统一。
虽然历史上大多把霍去病墓石雕群归为写意的类别,而唐昭陵六骏则被看作写实的代表,但在具体的形象塑造方面,这两种艺术手法相互渗透。
昭陵六骏继承了霍去病墓的创作手法,采用象征手法,表现重大的历史事件。
这两组石雕虽然都刻画的是战马,实质是反映人的勇敢和战争的惨烈。
因此不管是霍去病墓石雕还是昭陵六骏,不仅是对帝王将相的颂歌,也是无数英勇将士的历史丰碑。
霍去病墓纪念性石雕的重要特点,是将独特的艺术构思和石料的选取相结合,因石而得形,因形而造意,因意而施工。
《马踏匈奴》是霍去病墓石雕群中最具代表性的一件作品。
作品中战马威武雄健,傲然挺立,敌人蜷缩于马下,垂死挣扎,与整个马的轮廓浑然一体。
而在整个雕塑的关键部分,如马下胡人的特征运用线刻和浮雕的手法刻出相对写实的形象。
这样,将大写意与细微写实的造型手法相结合来表现精妙传神的形象。
就马的造型而论,汉马偏于写意,蹄细体肥,外形流畅简洁;唐马偏于写实,注重马体解剖结构的表现。

2021届诸城市第一中学高中部高三英语一模试题及答案解析
2021届诸城市第一中学高中部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AWhen it comes to the greatest inventions of the world, China’s name is sure to be mentioned several times. There are hundreds of things which were invented by the Chinese.AlcoholShocked? I was because when they said alcohol I thought about either the US or the UK. China had never crossed my mind. In China, alcohol was made by two legendary persons named Yi Di and Du Kang who belonged to the Xia Dynasty. This period was about 2000 BC - 1600 BC. Research says that in ancient China, beer with 4% alcoholic content was widely consumed by people.TeaChina is the proud inventor of tea which was first drunk by Shen Nong, a Chinese emperor around 2737 BC. Tea production was rapidly developed, making tea a popular drink during the Tang and Song Dynasties.The Mechanical ClockHave you ever wondered what on earth we would be doing without any idea of time? A clock really is an invention without which things were incomplete. The credit of making the first mechanical clock goes to ancient China. The first mechanical clock was invented by Yi Xing in the Tang Dynasty. This was during 618 and 907.Silk FabricSilk, the favorite fabric of many girls out there, is also a Chinese invention. Although we all know that silk is made by silkworms, it was Chinese people who first invented a way to harvest the silk and then use it to make clothes. The oldest silk which has been found so far is in Henan Province and dates back to 3630 BC.1.We can learn from Paragraph 2 that ________.A.people in the US like alcoholB.beer was popular in the Xia DynastyC.Yi Di and Du Kang invented alcohol by accidentD.the author didn’t know alcohol is a Chinese invention2.The author asks the question in Paragraph 4 to show ________.A.ancient Chinese inventors were wiserB.many things in our lives are incompleteC.ancient Chinese people never wasted timeD.the invention of the mechanical clock is important3.Which of the following invention has a longer history?A.Tea.B.Alcohol.C.Silk fabric.D.The mechanical clock.BThose who are concerned that robots are taking over the world can rest easy—for now. Though the androids have proved useful at performing ordinary tasks, they are not ready for the greatest time. At least that appears to be the case atJapan’s Henn-na Hotel chain where over half of the robot staff are being replaced by humans.The first location of the unique hotel opened in July 2015 was atNagasaki’s Huis Ten Bosch Theme Park. The hotel’s owner, Hideo Sawada, promised the hotel to be managed primarily by robots. Guests were greeted and checked-in by a dinosaur robot, while a cute android called Churi, placed inside each room, provided information about attractions. Not surprisingly, the lodging, recognized in 2016 as the world’s first robot-staffed hotel by Guinness World Records, drew in curious visitors from all around the world.But as the years have passed, the hotel’s main draw is becoming less novel and more unsatisfactory. Also as the robots are “aging”, they are costing more to repair. Among the 283 androids being replaced are the chain’s two dinosaur receptionists. In addition to scaring young guests, they are also unable to photocopy guests’ passports, forcing human employees to step in each time. Also out are the cute Churi robots, which annoyed guests by interrupting their conversations. For example, one guest told The Wall Street Journal that Churi mistook his snoring for a command and kept asking him to repeat his request all night.Sawada told The Wall Street Journal, “When you actually use robots you realize there are places where they aren’t needed—or just annoy people.” While Sawada may be cutting back on his use of androids, the recently-opened Smart LYZ Hotel and the Fly Zoo Hotel inChina, are run entirely by robots, with not a human in sight. Whether the employees have more competence than those “hired” by the Henn-na Hotel chain remains to be seen.4. What makesJapan’s Henn-na Hotel unique?A. Its robot employees.B. Its advanced equipment.C. Its convenient location.D. Its successful management.5. What is the author’s purpose with the example in paragraph 3?A. To entertain readers.B. To prove Churi’s drawback.C. To introduce Churi’s functions.D. To persuade people not to book the hotel.6. What does the owner ofJapan’s Henn-na Hotel think of his robot staff now?A. Attractive.B. Costly.C. Pioneering.D. Disappointing.7. What is the best title for the text?A. Robots Are Taking Over the World.B. The Boom of Robots-staffed Hotel.C. Robot Staff Are Fired For No Competence.D. The First Robots-staffed Hotel Won Guinness World Record.CYour best friend that follows you around when the sun comes out - your shadow - doesn’t serve an important function like your heart or brain, but what if you could use shadows to create electricity? When using solar panels (电池板) that are powered by light, shadows can be boring because it means electricity can’t be created. However, researchers from the National University of Singapore have engineered a way to create power from the shadows present everywhere.A team of the university created a machine that can collect energy from shadows. It is created by placing a thin coating of gold onto silicon (硅). Like in a normal solar panel, when put in light, the silicon electrons (电子) become energized and the energized electrons then jump from the silicon to the gold. The voltage (电压) of the part of the machine that is placed in the light increases to the dark part and the electrons in the machine flow from high to low voltage. They are sent through an external circuit (外电路) creating a current that can be used to power another machine. The greater the contrast between light and dark, more energy is provided by the machine.The team isworking on improving the performance of the machine, borrowing approaches from solar panels to gather light. Increasing the amount of light the machines can receive allows them to better make use of shadows, as well as developing shadow energy collecting panels that can successfully gather from indoor lighting. The team is also researching the use of other materials other than gold to drop the price of the machine, meaning they would be more cost effective and easier to apply in society.Shadows are present everywhere and perhaps one day in the future we will be able to collect energy from them by placing the shadow-effect energy machine around the world in places that have been considered unfit for solar panels to work, or indoors. “A lot of people think that shadows are useless,” Tan says, but “anything can beuseful, even shadows.”8. What is Paragraph 1 mainly about?A. Your best friend always stays with you after the sunrise.B. The shadow has the same function as the heart and brain.C. Shadows can stop solar panels from creating electricity.D. Researchers have found a way to create power from shadows.9. What is the key working principle of the machine mentioned in the text?A. The silicon produces electricity when it is in the light.B. The gold produces power with the help of the silicon.C. The energized electrons flow from high to low voltage.D. An external circuit creates current using another machine.10. How does the team improve the performance of the machine?A. Using solar panels in the machine.B. Increasing the amount of light received.C. Developing light energy collecting panels.D. Bringing down the price of gold.11. Which of the following is the best place to apply the machine?A. A gym.B. A park.C. A farm.D. A playground.DIn the old days, when you had to drive to a movie theater to get some entertainment, it was easy to see how your actions could have an impact(影响)on the environment. After all, you were jumping into your car, driving across town, coughing out emissions(产生排放)and using gas all the way. But now that we're used to staying at home and streaming movies, we might get a littleproud. After all, we're just picking up our phones and maybe turning on the TV. You're welcome. Mother Nature.Not so fast, says a recent report from the French-based Shift Project. According to "Climate Crisis: The Unsustainable Use of Online Video", digital technologies are responsible for 4% of greenhouse gas emissions, and that energy use is increasing by 9% a year. Watching a half-hour show would cause 1. 6 kilograms of carbon dioxide emissions. That's like driving 6. 28 kilometers. And in the European Union, the Eureca project found that data centers(where videos are stored)there used 25% more energy in 2017 compared to just three years earlier, reports the BBC.Streaming is only expected to increase as webecome more enamored ofour digital devices(设备)and the possibility of enjoying entertainment where and when we want it increases. Online video use is expected to increase by four times from 2017 to 2022 and account for 80% of all Internet traffic by 2022. By then, about 60% of the world's population will be online.You're probably not going to give up your streaming services, but there're things you can do to help lessen the impact of your online use, experts say. For example, according to Lutz Stobbe, a researcher from the Fraunhofer Institute in Berlin, we have no need to upload 25 pictures of the same thing to the cloud because it consumes energy every time. If instead you delete a few things here and there, you can save energy. Moreover, it's also a good idea to stream over Wi-Fi, watch on the smallest screen you can, and turn off your Wi-Fi in your home if you're not using your devices.12. What topic is the first paragraph intended to lead in?A. The environmental effects of driving private cars.B. The improvements on environmental awareness.C. The change in the way people seek entertainment.D The environmental impacts of screaming services.13. What does the underlined phrase become more enamored of" in paragraph 3 probably mean?A. Get more skeptical of.B. Become more aware of.C. Feel much crazier about.D. Get more worried about.14. What can we infer about the use of streaming services?A. It is being reduced to protect the planet.B. Its environmental effects are worsening.C. It is easily available to almost everyone.D. Its side effects have drawn global attention.15. Which of the following is the most environmentally-friendly?A. Watching downloaded movies on a mobile phone.B. Downloading music on a personal computer.C. Uploading a lot of images of the same thing.D. Playing online games over mobile networks.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年诸城市第一中学初中部高三英语模拟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AReturns & Refund Guarantee(保证;保证书)The “Returns & Refund Guarantee” is a promise provided by sellers for every item they sell on DHgate. com. When you receive an item that was bought and paid for on our site, and you find it is not as described or isof low quality, you can contact the seller to resolve these problems. DHgate will offer additional assistance if the seller is not cooperative.Scope(范围)The following points should not be included in the “Returns & Refund Guarantee”:▲The seller didn't make any promise.▲The seller can provide evidence to prove the items are as described.▲You didn't contact the seller within the promised time.▲You have released the payment to the seller before asking DHgate for help.Sellers are able to set up the following promises:Returning items for any reasonBuyers can return items for a refund within a specific date which has been set up by sellers, such as 3 days, and 7 days from the day when the items are received. The items' receiving date is the date that is indicated on the shipping carrier's official website.

A total of 34,503 men were diagnosed(诊断)with a mental disorder.The study found thata mental disorder in young adulthond was linked to a higher risk of having heart attack by middle age. Compared to men without a mental illness in young adulthood,the risk of heart attack was 20%higher among men with a diagnosis.“We already knew that menwho were physically fit in adolescence seem less likely to keep fitness in later years if they have low stress resilience” said study author Dr. Bergh, “Our research has also shown that low stress resilience is also connected with a greater tendency towards bad behavior, such as higher risks of smoking, drinking and other drug use.”“Better fitness in adolescence is likely to help protect against later heart disease, particularly if people stay fit as they age. Physical activities may also reduce some of the bad effects of stress. Those in poor health could benefit from additional support to encourage exercise and develop plans to deal with stress,” said Bergh.4. How does the author develop paragraph 3?A. By giving examples.B. By listing figures.C. By making a comparison.D. By drawing a conclusion.5. What are men with low stress resilience likely to do?A. Smoke more.B. Eat more.C. Sleep less.D. Do less exercise.6. What will Bergh agree with according to the last paragraph?A. Physical activitiesadd to stress.B. Stress may cause heart disease.C. Taking exercise is unnecessary.D. Staying fit is of great importance.7. In which section of a newspaper may this text appear?A. Entertainment.B. Health.C. Education.D. Fashion.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.DWe asked four people who watched an online talk on technology and communication by Sherry Turkle for their opinions.Fred:The talk certainly gave me plenty of food for thought about how technology is changing our behaviour. People are constantly multitasking, whether it be emailing during meetings or texting in the checkout queue. It’s as if we can’t bear to miss out on what our online friends are up to, so we juggle the real and online world. My greatest concern is that we don’t give our brains a chance to switch off. It’sthese precious momentswhen we actually process information that helps us make important decisions.Jeremy:It was a fascinating talk and the speaker really hit the nail on the head with a couple of things. Take parental influence, for instance. How can we expect teenagers not to text while doing their homework when they witness their parents posting on social media while cooking the evening meal or waiting at a red light?Kath:So much of what the speaker said rang true. I honestly believe there’s a danger that the more connected we are, the more isolated we feel. I don’t think this is such an issue for my generation who’ve lived without technology for so long. We know how to be alone. But the under 20s are another kettle of fish. They’re so busy communicating that they never experience the feeling of solitude and run the risk of not learning how to enjoy their own company.Carl:I’m not sure to what extent I agree that people are more alone, but the way we communicate has certainly evolved. The speaker makes a good point about how we’re getting used to talking with machines like Siri or robots, which are totally lack of experience of human life. But despite such limitations, we seem to be expecting more from technology and less from each other.12. What does the underlined phrase “these precious moments” in paragraph 2 refer to?A. When our brains are free.B. When we emailing during meeting.C. When we texting in the checkout queue.D. When we juggle the real and online world.13. What suggestion may Jeremy give to the parents?A. Accompany their children when they are doing homework.B. Prevent their children using phone while doing homework.C. Set a good example for their children on using phone properly.D. Stop posting on social media in face of their children.14. What does Kath worry about the under 20s generation?A. They communicate more with others.B. They use more technology.C. It’s difficult for them to find companies.D. They don’t know how to be alone.15. What is Carl’s attitude towards the use of technology in communication?A. Favorable.B. Intolerant.C. Doubtful.D. Indifferent.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。

However, a new study provides evidence that the area had a rainforest in the past.The researchers collected a piece of Earth sediment from under the seafloor off the coast ofAntarctica. In the sediment, they discovered forest material that was estimated to be about 90 million years old. At that period, dinosaurs were the ruler animals of the land.Johann Klages, a German geologist, was the lead writer of a study on the findings, published in the journalNature. He said the sediment was collected from a depth of about 30 meters below the ocean floor. Klages said an examination showed that the material didn’t form in the ocean.The researchers estimate that the area — about 900 kilometers from the South Pole — had average yearly temperatures of about12°Cto13°C. The soil included fine dirt particles and hard clay, as well as substances linked to at least 65 different kinds of plants, the study found. Although no animal remains were found, Klages said there were likely dinosaurs, flying reptiles and many insects in the environment.The research represents new evidence of the major climate changes Earth experienced in the past — and is currently undergoing today. The soil in the sediment dates back to the planet’s warmest period of the past 140 million years, with sea level about 170 meters higher than today. The researchers said that the rainforest environment inAntarcticawas especially surprising because each year, the area experiences a four-month polarnight when there is no sunlight to fuel plant life. Klages said no ice sheets were present during the time, but seasonal snowfall was likely.4. What can we learn about the sediment collected?A. It formed in the age of dinosaurs.B. It was found on theAntarcticaland.C. Ancient forest material was found in it.D. Some dinosaur remains were found in it.5. How did the researchers reach their findings?A. By analyzing the Earth sediment.B. By exploring ice inAntarctica.C. By collecting data on climate.D. By researching special plants.6. What can be indicated in the last paragraph?A. Seasonal snowfall made the forest disappear.B. Antarctica was much colder 140 million years ago.C. Antarctica’s natural environment has changed greatly.D. Polar nights inAntarcticaare getting shorter than before.7. What is the main idea of the text?A. Rainforest disappeared fromAntarctica.B. Antarctica had a different history of climate.C. Researchers studied a piece of Earth sediment ofAntarctica.D.Antarcticahad an extreme environment containing ice and snow.CThink ofJapanin the spring and the image that comes to mind is likely the country’s famous cherry blossoms, also known as “Sakura” — white and pink flowers, blooming across cities and mountains.The flowers, which experience a “peak bloom” that only lasts a few days, have been loved inJapanfor more than a thousand years. Crowds celebrate with viewing parties,flockingto the most popular locations to take photos and have picnics underneath the branches.But this year, cherry blossom season has come and gone in the blink of an eye, in one of the earliest blooms on record. Scientists warn it’s a symptom of the larger climate crisis threatening ecosystems everywhere.Yasuyuki Aono, a researcher atOsakaPrefectureUniversity, has gathered records fromKyotoback to 812 AD from historical documents and diaries. In the central city ofKyoto, cherry blossoms peaked on March 26, the earliest in more than 1,200 years, Aono said. And in the capitalTokyo, cherry blossoms reached full bloom on March 22, the second-earliest date on record.The peak bloom dates shift every year, depending on numerous factors including weather and rainfall, but have shown a general trend of moving earlier and earlier. InKyoto, the peak date stayed around mid-April for centuries, but began moving into early April during the 1800s. The date has only dipped into late March a handful of times in recorded history.“Sakura blooms are very temperature sensitive,” said Aono. “Flowering and full bloom could be earlier or later depending on the temperature alone,” he said. “The temperature was low in the 1820s, but it has risen by about 3.5 degrees Celsius to this day.”This year’s seasons in particular influenced the blossom dates, he added. The winter was very cold, but the spring came fast and unusually warm.8. What is the best title of the passage?A. Cherry blossom celebrations.B. Warning of a climate crisis.C. A strong love for cherry blossom.D. Cherry blossom season coming earlier.9. What does the underlined word “flocking” mean?A. Blocking.B. Flooding.C. Running.D. Following.10. What can we infer from paragraph 5?A. The peak blossom dates fall on a fixed date.B. The cherry blossom rarely peaks in March.C. The peak bloom dates mainly depend on weather and rainfall.D. Cherry blossom peaks around mid-April inTokyo.11. What is the author’s purpose in writing the passage?A. To inform people the date of cherry blossom.B. To show a study on cherry blossom dates.C. To present a Japanese tradition of cherry blossom celebration.D. To make people aware of the influence of climate change on cherry blossom.DA nurse has fulfilled (实现) a promise she made to her patient four years ago to one day attend her daughter's graduation from nursing school.Edina Habibovic, 22, graduated from Chamberlain University's College of Nursing in 2020. Her mother, SevalaHabibovic, 46, died in2017 after a two year fight with breast cancer.“I thought the medical field wasn't for me. Then, my mom got sick and I had all the experience going in and out of the hospital, ” Edina toldGood MorningAmerica. “When my mom passed away, I thought, ‘I want to dothis.’”she said.Sanja Josipovic, who at the time worked as a home health nurse with Northwestern Medicine in Winfield, Illinois, cared for Sevala inside her home. They often chatted and shared the latest news with each other over six months of care.“She was most worried about Edina because she was young and hadn't finished school yet, ” Sanja said. “We are like sisters; we care about and trust each other.

2021届诸城市第一中学高中部高三英语月考试题及答案解析
2021届诸城市第一中学高中部高三英语月考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AThe Origins of Famous BrandsOur lives are full of brand names and trademarked products that we use every day. Although many brand names are simple acronyms(首字母缩略词) or versions of their founders names, some of the companies we trust every day actually have fascinating and surprising back stories.StarbucksIt seems fitting that the most famous coffee brand in the world would take its name from one of the world’s greatest works of literature. The inspiration for the name of the coffeehouse came from Herman Melville’sMoby Dick. The founders’ original idea was to name the company after the Captain Ahab’s ship, but they eventually decided that Pequot wasn’t a great name for coffee, so they chose Ahab’s first mate, Starbucks, as the name instead.GoogleGoogle was originally called Backrub, for it searched for links in every corner of the Web. In 1997, when the founders of the company were searching for a new name showing a huge amount of data for their rapidly improving search technology, a friend suggested the word “googol”. When a friend tried to register the new domain (域) name, he misspelled “googol” as “google”.NikeOriginally founded as a distributor for Japanese running shoes, the company was originally named BRS, or Blue Ribbon Sports. In 1971, BRS introduced its own soccer shoe, a model called Nike, which is alsothe name for the Greek goddess of victory. In 1978, the company officially renamed itself as Nike, Inc.The right name is essential to a company’s success, and a great origin story is just as important as a great product. An attractive origin story is one more thing that keeps customers guessing, wondering, and buying its products.1. What is the name of the Captain Ahab’s ship?A. Moby Dick.B. Starbucks.C. Pequot.D. Herman Melville.2. Why did the founders of the Google want to change its name?A. They mistook their name.B. They wanted new customers.C. The company’s original name was too long.D. The company’s search technology was improving rapidly.3. Where does the importance of the origin story of one company lie in?A. It can change the company’s image.B. It can add myth to the company.C. It explains the development of the company to customers.D. It makes customers imagine and purchase its goods.BImagine that youare a superhero. Your superpowers are activated by a special suit. The suit communicates with your brain. It allows you to do amazing things with only a thought. By concentrating on strength, for example, you can kick a soccer ball across a field. By focusing on swift actions, you can jump to the top of a tree.Such a connection between mind and machine may sound like a fantasy. To scientists, though, it is a very real goal. They are creating machines that let disabled monkeys walk. These machines may soon help disabled humans do the same. Unlike other bionic devices, these robotic “super suits” do not communicate with muscles and nerves. Instead, they have a direct line to the brain.In 2005, doctors drilled a hole in the skull of Hutchinson, who had lost her right arm in an accident. Then they inserted a sensor onto her motor cortex (大脑皮层运动区). Wires connected the sensor to a receiver on her head. After she recovered, researchers pluggedHutchinson’s receiver into a cable that relayed signals from her brain to computers. Then they connected a robotic arm to the computers. The computerscould interpretHutchinson’s brain signals to move the arm.Soon,Hutchinson, the computer, and the robotic arm became a team.Hutchinsonwas even able to lift her hand and drink from a cup. “She smiled when she put down that drink—that’s everything.” says Donoghue, a brain scientist.Today other scientists are building on that success. One of those scientists is Dr. Miguel Nicolelis, who designed a whole-body bionic equipment. In 2014, a disabled former athlete kicked the first ball of the World Cup Games wearing one of Miguel’s full-body exoskeletons.The exoskeleton was connected to brain signal sensors in the man’s cap. By thinking about kicking, he sent signals to a computer on his back. The computer then translated the signal into an exoskeleton-aided kick. Suchdesigns may become common as scientists keep merging mind and machine.4.Which can best describe the tone of paragraph 1?A. Narrative and serious.B. Persuasive and critical.C. Informative and objective.D. Descriptive and imaginative.5. What is paragraph 3 mainly about?A. Reason of the experiment.B. Results of the experiment.C. Process of the experiment.D. Significance of the experiment.6. Why is Dr. Miguel’s exoskeleton special?A. It can be used on animals.B. It can move the whole body.C. It was supported by computers.D. It was connected directly to the brain.7. What can be inferred from the last paragraph?A. Robotic suits may be widely used to help disabled people.B. Exoskeleton is more common thanHutchinson’s bionic arm.C.Scientific experiments are commonly carried out in football fields.D. Disabled athletes can now play football again with the help of computer.CPigeons inLondonhave a bad reputation. Some people call them flying rats. And many blame them for causing pollution with their droppings. But now the birds are being used to fight another kind of pollution in this city of 8.5 million.“The problem for air pollution is that it’s been largely ignored as an issue for a long time,” says Andrea Lee, who works for the London-based environmental organization Client Earth. “People don’t realize how bad it is, and how it actually affects their health.”London’s poor air quality is linked to nearly 10,000 early deaths a year. Lee says, citing(引用)a report released by the city manager last year. If people were better informed about the pollution they’ re breathing, she says, they could pressure the government to do something about it.Nearby, on a windy hill inLondon’s Regent’s Park, an experiment is underway that could help—the first week of flights by the Pigeon Air Patrol. It all began when Pierre Duquesnoy, the director for DigitasLBi, a marketing firm,won a London Design Festival contest last year to show how a world problem could be solved using Twitter. Duquesnoy, fromFrance, chose the problem of air pollution.“Basically, I realized how important the problem was,” he says. “But also I realized that most of the people around me didn’t know anything about it.” Duquesnoy says he wants to better measure pollution, while at the same time making the results accessible to the public through Twitter.“So”, he wondered, “how could we go across the city quickly collecting as much data as possible?” Drones were his first thought. But it’s illegal to fly them overLondon. “But pigeons can fly aboveLondon, right?” he says. “They live—actually, they are Londoners as well. So, yeah, I thought about using pigeons equipped with mobile apps. And we can use not just street pigeons, but racing pigeons, because they fly pretty quickly and pretty low.”So it might be time for Londoners to have more respect for their pigeons. The birds may just be helping to improve the quality of the city’s air.8. What can we infer aboutLondon’s air quality from Paragraph 2?A. Londoners are very satisfied with it.B. The government is trying to improve it.C Londoners should pay more attention to it.D. The government has done a lot to improve it.9. Duquesnoy attended the London Design Festival to _________.A. entertain Londoners.B. solve a world problem.C. design a product for sale.D. protect animals like pigeons.10. Why did Duquesnoy give up using drones to fly acrossLondon?A. Because they are too expensive.B. Because they fly too quickly.C. Because they are forbidden.D. Because they fly too high.11. Which can be the best title for the text?A. Clean air inLondon.B. London’s dirty secret.C. London’s new pollution fighter.D. Causes of air pollution inLondon.DThere are many useful things we can do each day to feel better. It may take some efforts and time to make a habit of drinking 8 glasses of water daily or thinking more positively, but it is well worth it. What things do you do every day to feel better?Probably the healthiest thing you can do to feel better each day is to exercise early in the morning. You don'thave to run the whole morning or spend a few hours in the gym. Even doing some easy exercise like walking, sit-ups or jumping the rope will help you feel better in no time!Again, due to our busy schedules, we don't get enough sleep each night. If you have trouble falling asleep, avoid watching TV or surfing the Internet right before bed. Also, try to make healthy bedtime snack choices and don't drink tea or coffee too late in the day.If you drink 3 glasses of water, 4 glasses of coffee or tea and a glass of soda each day and think that you drink enough water, think again. Your body needs water (not coffee or soda!) to function properly. Aiming to drink 7-8 glasses of water each day can make you feel better.Being positive is the key to a longer life. Positive thoughts can help improve your overall heath. Life is full of stressful situations and it's hard to stay cheerful when everything goes wrong, but your positive attitude can help you solve any problem and fight any stress faster and easier. Your positive attitude is especially good for your heart health. Smile, stay positive and live a longer life!12. In the author's opinion which can benefit us most in order that we feel better?A. Sleeping enough.B. Drinking enough water.C. Thinking more positively.D. Taking morning exercise.13. Which of the following agrees with what is said in Paragraph 3?A. Drinking tea or coffee makes us sleep less.B. Drinking tea before bed makes it harder to fall asleep.C. Watching TV or surfing the Internet leads to less sleep.D. Our busy schedules cause more difficulty in falling asleep.14. Why is water necessary to our body?A. Because it can make us feel better.B. Because it can have our body work smoothly.C. Because in can do more good to our body thancoffee.D. Because it can hep avoid feeling thirsty.15. What do we need most when everything goes wrong?A. Thinking positively.B. Thinking out wise ways.C. Having a right attitude.D. Staying cheerful.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。

At the click of a keyboard) you could enter an overall view but private visual salon, without having to brave the airless Hong Kong Convention and Exhibition Centre.There, on one webpage, was Jeff Koons riffing(翻唱)on Botticelli's "Primavera" in a tribute to the history of painting at David Zwirner Gallery. Ota Fine Arts offered one collector the chance to acquire an "infinity(无限)room“, one of the most Instagrammed artworks of recent years- the creation of the fantasies,nonagenarian (九十多岁) Japanese artist, Yayoi Kusama. White Cube presented a large collection of international works by Andreas Gursky (German), Theaster Gates (American) and Beatriz Milhazes (Brazilian). But not every artist, gallery and form showed to equal advantage in this alternative fair. Not surprisingly, simple two-dimensional works in bright colours came across best No sculpture or conceptual art was includedBesides depth and texture, there are aspects of gallery hopping that a website is unlikely to copy. One isserendipity—the sense of wandering between artworks and encountering the unexpected. Another is sociability. Art is a communion between artist and viewer, but galleries and fairs are also places to swap opinions and share enthusiasms.Thereare ways to compensate (or these inevitable(不可避免的)disadvantages. As they shut their physical doors, some of the world's nest galleries and museums are offering advanced interactive visits, 360 degree videos and walk around tours of their collections, allwithout queues and high ticket prices.

Virtual and augmented(增强的)realities are together known as mixed reality (MR). “American footballers are already using VR to better train their minds andread the field,” Ludden said. “This can allow players to perfect their skills without risking injury.”Canadian company D-BOX Technologies designs and produces moving seats found in cinema and theme parks. It is now moving into sports, and shows its Formula One (F1) racing simulator(模拟器). The seats stimulate the force of gravity, speed and every shaking as Fl champion Lewis Hamilton zips around city streets.A simulation seat uses pre-programed data now. Someday, though, it could use real-time information sent bythe car. “They couldbroadcast live content through a network in pop-up theaters around the world,” Ludden said. Say you want to experience the true stress of a batter being up against major-league baseball pitcher. “You can have a heartbeat added to the sensation on the seat and then you can feel it, boom, boom,” Maheu explained. “When he swings and hits the ball, you can have an impact.”One day, fans around the world could physically experience every game from their favorite player in real time. Ludden said that current and near-future technology could create “augmented stadiums” for live audiences. Panasonic launched its “Smart Venue” plans which included the overlaying of graphics, advertisements, player statistics and replays on the field of play at a pro football game. “If you are seated in the cheap seats, you can see this really useful.” “Fans may someday join in stadium wide games, using the field as a virtual gaming platform,” Ludden added.12.
