Her mother, Sevala Habibovic, 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. She was a powerful and strong minded woman. She wasn't scared to die; she was just worried about her kids and husband.”Edina said her mother lived for being with her family and taking care of people. “When Sanja was working, my mom would still try to make her something to eat, no matter how sick she was, ” Edina added. When Sevala's life was coming to an end, she asked Sanja to take her place at her youngest daughter's nursing school graduation. “That was the only thing she was going to miss. Edina's graduation, ” said Sanja, who is a mother of three herself. She agreed.Due to COVID -19, there was no graduation or pinning ceremony.

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everywhere.Yasuyuki Aono, a researcher atOsakaPrefectureUniversity, has gathered records fromKyotoback to 812 AD from historical documents and diaries.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, theearliest 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.DAfter almost an entire year of not going shopping and vacationing, you find the numbers reflected by yourbank account meet your heart’ s desire.Now the most important question comes, what to do with the earnings? Should you fulfill dreams of the present, invest in preserving the future or perhaps keep saving it for a rainy day?Our elders always try to teach us the value of money and its moral weakness. One may be on a winning streak (连续成功) now, but it will not always be so. One will have days when there will be no sunshine but only rain, and their luck will hide behind those thick grey clouds. Save for those rainy days, they say. Do not spend too much, live within a budget,refrain fromcredit no matter how small and save for the future.Since the very first time we earn our own money from a summer job or earning our first salary, the lessons start. In fact, the pocket money that we receive when we are children begins the process of learning how to best manage one’ s money.People often think like this — one day when I have enough money, I will travel the world. Then, once we do earn enough money, tomorrow’ s plans start shadowing our present ones. However, is it wise to keep living for that future? Will we still enjoy or even be able to backpack in our 50s? How will we ever enjoy our present if we are constantly living for the future?Good questions, aren’ t they? I say travel but don’ t let yourself run dry, treat yourself to some luxuries but also keep enough for your necessities, and enjoy your present but with a plan for the foreseeable future. Life is for the living, so live it sensibly.12. Why do elders teach us to save money?A. Because there are more rainy days in life.B. Because no one can win streak.C. Because good days may end.D. Because money can’t buy everything.13. What does the underlined phrase “refrain from” mean in Paragraph 3?A. select fromB. hold backC. rely onD. prefer to14. Which of the following opinions would the author agree?A. To enjoy yourself in the right time.B. To wait to travel until we have enough money.C. To go backpacking in our 50s.D. To live for the future.15. What should we do with the earnings according to the author?A. We should save all for rainy days.B. We should fulfill our dreams.C. We should entertain ourselves.D. We should live the present wisely.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。

2019-2020学年山东大学附属中学高三英语第四次联考试题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AThere have been many great painters in the rich history of Chinese art. Here are four of the greatest painters from China.Li Cheng (919—967, Five Dynasties and early Song Dynasty)Li Cheng contributed greatly to one of the golden ages of landscape paintings in world history. During his time, he was considered the best landscape painter ever. He is remembered especially for the winter landscapes he created and for simple compositions of tall, old evergreens set against a dry landscape. Several of his paintings are in thin ink which gives them a foggy appearance.Fan Kuan (990—1020 , Song Dynasty)Fan Kuan began his career by modeling Li Cheng's work but later created his own style, claiming that the only true teacher was nature. His finest workTravelers among Mountains and Streamsis a masterpiece of landscape painting and many future artists turned to it for inspiration.Qi Baishi (1864-1957)One of the greatest contemporary Chinese painters, Qi Baishi is known for not being influenced by Western styles like most painters of his time. He can be considered as the last great traditional painter of China. He painted almost everything from insects to landscapes. He is regarded highly in Chinese art for the freshness that he brought to the familiar types of birds and flowers, insects and grass.Wu Guanzhong (1919—2010)Widely considered as the founder of modern Chinese painting , Wu Guanzhong has painted various aspects of China, like its architecture, plants, animals, people and landscapes. Wu went on to combine Western and Chinese styles to create a unique form of modem art. In 1992, he became the first living Chinese artist whose work was exhibited at the British Museum.1.What do we know about Li Cheng?A.He loved landscape paintings.B.He copied many artists' work.C.His work gained worldwide recognition.D.He was considered as Fan Kuan's teacher.2.What is the main feature of Qi Baishi's paintings?A.They have foggy appearances.B.They lack diversity in the theme.C.They come under Western influence.D.They show advanced traditional painting skills.3.What did the four Chinese painters have in common?A.They were all modern painters.B.They all created landscape paintings.C.They were all impacted by Western art.D.They were all pioneers intraditional art history.BWhy can friendships be hard? Because often people aren't as honest and open as they should be. Sometimes, people end up getting hurt.Most problems with friendships come up because people are just too selfish to care about the things that their friends need. They care about their own needs much more, which makes it hard for friendships to work. However, being selfish is part of human nature. A person is put together in order to take care of himself and his own needs, not necessarily those needs of other people. Even though being selfish is something that all humans are born with, it is something that everyone should guard against.The best thing to remember when you are a friend to anyone is that you need to treat your friend the same way as you'd like to be treated. This is wonderful advice for a friendship, because it is really the only way to make sure that you are giving your friend everything you would want to be given in a friendship. Whenever you have a question about how you should treat a friend, it is easy to find an answer simply by asking yourself what you would like your friend to do for you, if he or she is in your shoes.Even if you're always thinking about how you'd like to be treated, and your friends are too, there are issues that come up from time to time in each friendship, and it is important to understand how to deal with these issues so that you can build stronger and healthier friendships. Issues like friends getting boyfriends or girlfriends and not spending enough time with their friends, or even friends finding new friends and leaving old friends behind are issues that will probably come up with one or more of your friendships. It is important to know how to deal with these issues so that you can keep your friends and make new ones. No one wants to have a broken friendship.4. Why may problems with friendships appear?A. One is selfish.B. One is alone.C. One is too anxious.D. One is too busy.5. What's the first and most important thing to be other people's friend?A. Not to hurt your friends' feelings.B. To give your friends whatever you have.C. To treat your friends as fairly as possible.D. Not to think of your own needs any more.6. What is the text mainly about?A. The Meaning of FriendshipsB. The Importance of FriendshipsC. The Advantages of FriendshipsD. The Problems with Friendships7. What may follow the last paragraph of the text?A. How to make many friends.B. How to keep friends happy.C. How to treat friends correctly.D. How to solve friendship issues.CSix Neanderthals who lived in what is now France were eaten by their fellow Neanderthals some 100,000 years ago, according to fearful evidence of the cannibalistic (食人的) event discovered by scientists in a cave in the 1990s. Now, researchersmay have figured out why the Neanderthals, including two children, became victims of cannibalism: Global warming.While previous studies have examined Neanderthal remains to find proof of cannibalistic behavior, this is the first study to offer clues as to what may have led Neanderthals to become cannibals. Scientists found that rapid changes in local ecosystems as the planet warmed may have wiped out the animal species that Neanderthals ate, forcing them to look elsewhere to fill their stomachs.The researchers examined a layer of sediment (沉积物) in a cave known as Baume Moula-Guercy, in southeastern France. In that layer, charcoal (碳) and animal bones were so well-preserved that scientists could reconstruct an environmental picture representing 120,000 to 130,000 years ago. They discovered that the climatein the area was likely even warmer than it is today, and that the change from a cold, dry climate to a warmer one happened quickly. “Maybe within a few generations”, study co-author Emmanuel said. As the animals that once populated the landscape disappeared, some Neanderthals ate what they could find — their neighbors.Cannibalism is by no means unique to Neanderthals, and has been practiced by humans and their s “from the early Palaeolithic to theBronze Age and beyond,” the study authors reported. The behavior adopted by the starving Neanderthals in the Baume Moula-Guercy should therefore not be viewed as “a mark of bestiality (兽性) or sub-humanity”, but as an emergency adaptation to a period of severe environmental stress, according to the study.8. What does the study mainly focus on?A. The social behavior of Neanderthals.B. The reason for cannibalism among Neanderthals.C. The climate change in southeasternFrance.D. The influence of global warming on ancient animals.9. What can possibly be used to describe the climate in southeasternFrance120,000 to 130,000 years ago?A. It was no warmer than it is today.B. It was first warm while later cold and dry.C. Its change was mild and went through quite a long process.D. Its change is a chief factor contributing to cannibalism.10. Which of the following might the study authors agree with?A. Neanderthals’ cannibalism showed their bestiality.B. Cannibalism was actually a measure the Neanderthals had to adopt to survive.C. Neanderthals’ cannibalism guaranteed their rule over other tribes.D. Only Neanderthals were found to have cannibalism in human history.11. Where can you most possibly find this passage?A. In a science journal.B. In a travel brochure.C. In a history book.D. In a geography book.DAt any moment, about half the world’s population is wearing denim（牛仔布）clothes. But few realize tiny bits of denim have been adding up to a surprising amount of pollution in water, as a new study shows.Sam Athey, one of the study’s authors, says, “Even though denim is made of a natural material—cotton, itcontains chemicals.” Cotton fibers were treated with many types of chemicals, she notes. Some improve its durability and feel. Others give denim its distinctive blue color1 .Athey and her team washed jeans and found that about 50,000 microfibers came off from each pair per wash. Not all of those fibers make their way into the environment. Wastewater treatment plants catch about 83 to 99 percent ofthem. Catching 99 percent may sound pretty good. But one percent of 50,000 is still 500 fibers per wash. And since every pair of jeans is washed again and again, it still adds up to lots of microfibers entering the water environment.Denim microfibers showed up in sediment（沉淀物）from the Great Lakes. More of these fibers polluted a series of shallow lakesin southern Ontario. They even turned up in sediment from the Arctic Ocean in northern Canada. The team found denim accounted for 12 to 23 percent of microfibers in the sediment. There were other microfibers too. But the team focused on denim because so many people wear jeans.“Everyone wears jeans so they could be our largest input of microfibers into our streams and soils,” Athey says. “An easy way to limit that is by washing our jeans less often.” Athey grew up thinking she should wash her jeans after wearing them every couple of times, but most jean companies recommend washing them no more than once a month. “The solution is not that you shouldn’t wear jeans,” she says. “We need to buy fewer denim clothes and only wash them when they truly need it.”12. Which of the following is TRUE according to the passage?A. Chemicals are contained in natural cotton.B. Chemicals can make denim color1 ful.C. Chemicals prevent fibers from falling.D. Chemicals can make the life of denim longer.13. What does the underlined word “them” in Paragraph 3 refer to?A. Denim.B. Sediment.C. Microfibers.D. Chemicals.14. What does the author mainly want to tell us through Athey’s words ?A. To avoid wearing jeans.B. To reduce denim consumption.C. To wash jeans more often.D. To limit input in denim production.15. In which section of a magazine might the text be found?A. Science.B. Entertainment.C. Tourism.D. Geography.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。

2019-2020学年山东师范大学附属中学高三英语第四次联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ANo one knows when the first printing press was invented or who invented it. but the oldest known printed text originated in China during the first millennium (千年) AD.The Diamond Sutra (《金刚经》), a Buddhist book from Dunhuang, China during the Tang Dynasty, is said to be the oldest known printed book.The Diamond Sutrawas created with a method known as block printing (雕版印刷), which used boards of hand-carved wood blocks in reverse.It was said that the moveable type was developed by Bi Sheng. He was fromYingshan,Hubei,China, living from 970 to 1051 AD. His method replaced panels of printing blocks with moveable individual Chinese characters that could be reused. The first moveable Chinese Characters were carved into clay and baked into hard blocks that were then arranged onto an iron frame that was pressed against an iron plate.The earliest mention of Bi Sheng’s printing press is in the bookDream Pool Essays, written in 1086 by Shen Kuo, who noted that his nephews came into possession of Bi Sheng’s typefaces (字体) after his death. Shen Kuo explained that Bi Sheng did not use wood because the texture is inconsistent (不一致的) and absorbs wetness too easily.By the time of the Southern Song Dynasty, which ruled from 1127 to 1279 AD, books had become popular in society and helped create a scholarly class of citizens who had the capabilities to become civil servants. Large printed book collections also became a status symbol for the wealthy class.1. When was Bi Sheng’s printing press first introduced in history?A. After Bi Sheng died and his nephews owned his typefaces.B. When books became popular in the Southern Song Dynasty.C. After the block printing was replaced by the moveable type printing.D. WhenThe Diamond Sutrawas printed into a book.2. What can we infer from the passage?A. Shen Kuo made great contributions to printing.B. The moveable type printing was invented earlier than block printing.C. Printed books were hard to get in the Song Dynasty.D. By the Southern Song Dynasty, books had helped people get to higher social positions.3. Why does the author write this passage?A. To show that Buddhism was popular in the Tang Dynasty.B. To introduce the early history of printing.C. To memorize Bi Sheng, developing the moveable type printing.D. To indicate the advantages of moveable type printing.BThe first patient who died on my watch was an older man with a faulty heart. We tried to slow it down with treatment, but it suddenly stopped beating completely. Later, whenever I would have a case like that one, I found myself second-guessing my clinical management. However, it turns out that thinking twice may actually cause more harm than good.In a working paper, Emory University researchers found that when doctors delivering a baby have a bad result, they are more likely to switch to a different delivery method with the next patient, often unnecessarily and sometimes with worse results.Because doctors make so many decisions that have serious consequences, thefalloutfrom second-guessing appears especially large for us. A 2006 study found that if a patient had a bleed after being prescribed (开药) warfarin, the physician was about 20% less likely to prescribe later patients the blood thinner that prevents strokes (中风). However, if a patient was not on warfarin and had a stroke physicians were still no more likely to prescribe warfarin to their other patients.These findings highlight interesting behavioral patterns in doctors. In the blood-thinner study, doctors were more affected by the act of doing harm (prescribing a blood thinner that ended up hurting doctors were more affected by the act of doing harm(prescribing a blood thinner that ended up hurting a patient) and less affected by letting harm happen (not prescribing a blood thinner and the patient having a stroke). Yet a stroke is often more permanent and damaging than a bleed.But this phenomenon is not unique to medicine. ''Overreaction to Fearsome Risks'' holds true for broader society.For instance, sensational headlines about shark attacks on humans in Florida in 2001 caused a panic and led the state to prohibit shark-feeding expeditions. Yet shark attacks had actually fallen that year and, according to the study, such a change was probably unnecessary given the extremely small risk of such an attack happening.Humans are likely to be influenced by emotional and often irrational (不理性的) thinking when processing information, bad events and mistakes. As much as we don't want to cause an unfortunate event to happen again, we need to be aware that a worst situation that can be imagined doesn't necessarily mean we did anything wrong. When we overthink, we fail to rely on thinking based on what we know or have experienced. Instead, we may involuntarily overanalyze and come to the wrong conclusion.I have treated dozens of patients who presented with the same illnesses as my first patient, who died more than a year ago. Instead of second-guessing myself, I trusted my clinical instinct (本能) and stayed the course. Every one of those patients survived. You should trust your instinct in your life, too.4. The first two paragraphs suggest that________.A. bad medical outcomes affect doctorsB delivering babies can be difficult workC. some doctors are not very experiencedD. doctors sometimes make silly mistakes5. In the blood-thinner study, doctors________.A. tend to prescribe less effective medicineB. are more concerned about the patients' safetyC. become less confident in writing a prescriptionD. believe a stroke is more treatable than a bleeding6. What does the underlined word ''fallout'' in Paragraph 3 probably mean?A. ResultB. BenefitC. DifferenceD. Absence7. The author will probably agree that________.A. we should not doubt our own decisionsB. our experience will pave way for our futureC. humans are emotional and irrational on the wholeD. instincts don't necessarily lead to wrong directionsCWhen 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 information about 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. Because of the work of WIN, more and more people, like Alex and his team, are getting the message about safe disposal of e-waste. As Alex says, “Today’s technology should not become tomorrow’s harmful garbage.”8. What was Alex’s worry after he read the article?A. The littering of e-waste.B. The recycling of plastic.C. The change of environment.D. At 11 p.m. on Monday.9. What did Alex do to start the project?A. Set up WIN.B. Collect information.C. Ask friends for help.D. The overuse of old computer.10. Which can best describe the way Alex and his team did their work?A. Traditional.B. Competitive.C. Scientific.D. Convenient.11. What message does the story convey?A. There is no end to perfection.B. success comes through failure.C. Every positive attitude has a reward.D. young people can make a big difference.DHaley Curfman, 25, of Blackwell, Oklahoma, is a teacher at Blackwell Public School and last yearshe bought a plain(朴素的) white dress, which she set up a station in her classroom for her students to decorate, encouraging them to go and draw on the dress whenever they had free time. Haley set up a station at a table with the dress and some color1 ed markers so that her students could draw on it, having first seen the idea on Pinterest.After the kids had finished the design, she then surprised them all by wearing the dress to class, sharing pictures of herself in it on Facebook in a post that has since been shared over 200, 000 times.For teachers looking to do something similar for their own students, Haley said that she bought the dress off Amazon for less than $ 20 about six months ago and pre-washed the dress before she started the project. She used markers from Walmart. But she said these things can be bought in other places. She said, “To do the project, I set up a station at a table with the dress and markers. It takes anywhere from two weeks to a month to complete as we just work on it here and there when time allows. You'd better give the students enough time so they don't have to hurry.”“Teachers have been sharing their dresses, T-shirts, etc. with me that they've been creating since the 1950s with the same idea. It is amazing, and I love the fact that you are sharing them with me! Thank you all so much for your kindness and support,” she wrote on Facebook.Asked why she came up with the idea, Haley told Scary Mommy. “We don't have art in our school, so, I always try to do little creative projects when possible.”12. What did Haley use the plain white dress to do?A. To teach her students painting.B. To prepare for her presentation.C. To ask her students to draw on it.D. To help her students with their homework.13. What do we know about the finished dress?A. It took Haley by surprise.B. It is kept by Haley at home.C. It is the product of a new idea.D. It has enjoyed popularity online.14. What should a teacher do if he or she wants to follow Haley's example?A. Buy the same dress online.B. Give the kids enough time.C. Buy the same markers in Walmart.D. Leave the finished work untouched.15. Why did Haley carry out the project?A. To teach art to her students.B. To show her idea on Pinterest.C. To share it with other teachers.D. To exciteher students' creativity.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。

They found that the most environmentally friendly and cost-effective approach would be for more food producers to adopt the nitrogen-efficient “intensive” farming method, which involves the heavy use of labor and the production of more crops per acre.This approach was shown to be more effective than the “extensive” farming currently practiced by many poor nations, a method that includes clearing more new land to produce more food.Different farming methods produce significantly different yields, the researchers found — in 2005, the crop yields for the wealthiest nations were more than 300 percent higher than what the poorest nations produced.According to their analysis of the effects of extensive farming, if poorer nations continue using this method, by 2050theywill have cleared an area larger than theUnited States, about 2.5 billion acres. However, if wealthy nations help poorer nations to improve food yields by incorporating(吸收) intensive farming practices, that number could be reduced to half a billion acres.The researchers stress that the environmental effects of meeting future food demand depend on how global agriculture expands and develops.“Our analyses show that we cansave most of the Earth’s remaining ecosystems by helping the poorer nations of the world feed themselves,” Tilman said.4. What is the best title of this passage?A. The World Will Need Double Food by 2050B. Man Will Face the Risk of Lacking Food in the FutureC. Future Farmers Hold Environment’s Fate in Their HandsD. Different Farming Methods Produce Significantly Different Yields5. The character of the extensive farming is ________.A. very cost-effectiveB. to produce more crops per acreC. at cost of more new land to produce more foodD. very environmentally friendly6. It can be inferred from the passage that ________.A. poorer nations mainly use the intensive farmingB. wealthy nations mainly use the extensive farmingC. the intensive farming needs less food producersD. the extensive farming has a worse effect on ecosystems7. According to the passage, the underlined word “they” in the 7th paragraph refers to “________”.A. poorer nationsB. the effects of extensive farmingC. wealthy nationsD.future food demandCThe United Nations Educational, Scientific and Cultural Organization (UNESCO) included on December 17, 2020 China's Tai Chi on the Representative List of the Intangible（无形的）Cultural Heritage of Humanity. The decision was announced during the online meeting of the UNESCO Intergovernmental Committee for the Safeguarding of the Intangible Cultural Heritage held from December 14 to19 inKingston, capital ofJamaica.“Born in the mid-17th century in a small village named Chenjiagou located in Central China's Henan province, Tai Chi is not only a kind of traditional Wushu integrated with slow movements and deep breathing, but is also deeply rooted in many areas of Chinese culture, such as medicine and philosophy,”Zhu Xianghua says, who is the son of the famous Tai Chi master Zhu Tiancai.Although it has spread to more than 150 countries and regions, attracting more than 100 million people to practice, the idea that Tai Chi is for the elderly has stopped many young people practicing the ancient Wushu.They think of it as a slow exercise, which is specially made and better suited for their grandparents. Instead, many young people are turning to the Indian practice of yoga（瑜伽）to relieve stress, which was placed on the UNESCO's List in 2019.In order to promote Tai Chi, joint efforts have been made from individuals and the Chinese government in the last decades. Xi'an Jiaotong University requires students to learn Tai Chi. Wang Yunbing, a professor in the university's sports center, stressed that Tai Chi is not only good physical exercise-researchers from the American College of Rheumatology find that it can help manage several diseases but is also conned ted to ancient Chinese eivilization. Since 2014, the World Tai Chi Championships have been held every two years by the International Wushu Federation. It provides a platform for communication and learning between the Tai Chi masters and Tai Chi lovers around the globe. In January 2020, Tai Chi became an official event in the 2026 Dakar Youth Olympic Games.8. What does Zhu Xianghua say about Tai Chi in paragraph 2?A. It originated from fast Kung Fu action.B. It was born around the 1750s in a village.C. It is related to other cultural fields ofChina.D. It integrates Chinese medicine and western philosophy.9. Why do some young people choose to practice yoga instead of Tai Chi?A. They think it easier to practice yoga to keep fit.B. The elderly stop young people practicing Tai Chi.C. They consider Tai Chi is custom-built for old people.D. Yoga was included in the world culture earlier than Tai Chi.10. What is the main purpose of the last paragraph?A. To promote contemporary Chinese civilization.B. To show many efforts made to popularize Tai Chi.C. To stress the importance of Chinese Tai Chi masters.D. To advise people to practise Tai Chi to cure diseases.11. Which of the following is the best title for the passage?A. Tai Chi Steps on the UNESCO's List.B. Tai Chi isCompeting against Yoga.C. Tai Chi Has Regained populate Globally.D. Opinions Greatly Differ on Tai Chi and Yoga.DWe use what is known as inner speech, where we talk to ourselves, to evaluate situations and make decisions. Now, a robot has been trained to speak aloud its inner decision-making process, giving us a view of how it responds to contradictory demands.Arianna Pipitone and Antonio Chella at the University of Palermo, Italy, programmed a humanoid robot named Pepper, with software that models human cognitive(认知的)processes, which allowed Pepper to retrieve (检索)relevant information from its memory and find the correct way to act based on human commands, as well as a text — to — speech processor. It allowed Pepper to voice its decision-making process while completing a task, "With inner speech, we can better understand what the robot wants to do and what its plan is," says Chella.The researchers asked Pepper to set a dinner table according to etiquette (礼仪)rules they had programmed into the robot. Inner speech was either enabled or disabled to see how it affected Pepper's ability to do what was instructed.When instructed to place a napkin on a fork with its inner speech enabled, Pepper asked itself what the etiquette required and concluded that this request went against the rules it had been given. It then asked the researchers if putting the napkin on the fork was the correct action. When told it was, Pepper said, "OK, I prefer to follow your desire," and explained how it was going to place the napkin on the fork.When asked to do the same task with inner speech disabled, Pepper knew this contradicted etiquette rules, so it didn't perform the task or explain why.With the potential for robots to become more common in the future, this type of programming could help the public understand their abilities and limitations, says Sarah Sebo at theUniversityofChicago. "It maintains people's trust and enables cooperation and interactions between humans and robots," she says. However, this experiment only used a single human participant, says Sebo. "It's unclear how their approach would compare across a wide range of human participants," she says.12. Why does the author mention how people make decisions in the first paragraph?A. To introduce the topic.B. To make comparisons.C. To provide an example.D. To support his argument.13. How did Pepper react to the contradictory instruction with its inner speech enabled?A. It failed to complete the task.B. It followed the etiquette rules.C. It made a random decision.D. It communicated with the researchers.14. What did Sarah Sebo think of the research?A. It was creative but worthless.B. It was a good try but the result was a failure.C. It was inspiring but needed further evidence.D. It was carefully designed but poorly performed.15. Which of the following is the best title for the text?A. Robot Taught To Be PoliteB. Robot Can Explain Its DecisionC. Robot Making Decisions: No Longer A DreamD. Robot-Human Communication: No Longer A Problem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。
