It was a large celebration.All of their friends and family came to see the lovely ceremony and to partake of the festivities and celebrations. All had a wonderful time.The bride was gorgeous in her white wedding gown and the groom was very dashing in his black tuxedo. Everyone could tell that the love they had for each other was true.A few months later, the wife came to the husband with a proposal, “I read in a magazine, a while ago, about how we can strengthen our marriage,”she offered.“Each of us will write a list of the things that we find a bit annoying with the other person. Then, we can talk about how we can fix them together and make our lives happier together.”Her husband agreed. So each of them went to a separate room in the house and thought of the things that annoyed them about the other. They thought about this question for the rest of the day and wrote down what they came up with.The next morning, at the breakfast table, they decided that they would go over their lists.“I’ll start,”offered the wife. She took out her list. It had many items on it. Enough to fill 3 pages in fact. As she started, reading the list of the little annoyances, she noticed that tears were starting to appear in her husband’s eyes.“What’s wrong?”she asked.“Nothing,”the husband replied, “keep reading your list.”The wife continued to read until she had read all three pages to her husband. She neatly placed her list on the table and folded her hands over the top of it.“Now，you read your list and then we’ll talk about the things on both of our lists,”she said happily.Quietly the husband stated, “I don’t have anything on my list. I think that you are perfect the way that you are. I don’t want you to change anything for me. You are lovely and wonderful and I wouldn’t want to try and change anything about you.”The wife, touched by his honesty, the depth of his love for her, and his acceptance of her, turned her head and wept.[共5题](1) Which is NOT true according to the passage?(A) The man and his girlfriend had a great wedding.(B) The woman wanted reasons for a divorce.(C) The man respected his wife very much.(D) The woman was moved by her husband’s kindness.正确答案：B(2) The woman suggested writing down another’s weak points, in order to ________.(A) make her marriage better(B) show her annoyance with her husband(C) let other people know(D) help her husband think independently正确答案：A(3) What is the writer’s attitude to the husband’s behavior?(A) Positive(B) Ironical(讽刺的)(C) Opposite(D) None of the above.正确答案：A(4) According to your understanding, why did tears appear in the husband’s eyes?(A) Because his wife was too perfect.(B) Because he accepted her as a whole, but she didn’t.(C) Because he loved her more than she loved him. -(D) Because his wife was too rude (粗鲁的).正确答案：B(5) It can be inferred from the passage that the wife(A) would shorten her list.(B) would not let other people know her husband’s bad aspects.(C) would learn to respect and accept her husband fully.(D) would be confused.正确答案：C43.Maybe it is true that we don’t know what we have got until we lose it, but it is also true that we don’t know what we have been missing until it arrives. Giving someone all your love is never an assurance that they will love you back. Don’t expect love in return; but be content that love has grown in your own heart.It takes an hour to like someone, a day to love someone, but it takes a lifetime to forget someone. Don’t rely on one’s appearance; it can deceive. Don’t rely on wealth; even that fades away. Rely on someone who makes you smile, because it takes only a smile to make a dark day seem bright. There are moments in life when you miss someone so much that you just want to pick them from your dreams and hug them. Dream what you want to dream; go where you want to go; be what you want to be, because you have only one life and one chance to do all the things you want to do. May you have enough happiness to make you sweet, enough trials to make you strong, enough sorrow to keep you human, enough hope to make you happy.Always put yourself in others’shoes. If you feel that it hurts you, it probably hurts others, too. The happiest of people don’t necessarily have the best of everything; they just make the most of everything that comes along their way. Happiness waits for those who cry, those who have been hurt, those who have searched, and those who have tried, for only they can appreciate the importance of people who have touched their lives.The brightest future will always be based on a forgotten past. You can’t go on well in life until you let your past failures and heartaches go off. When you were born, you were crying and everyone around you was smiling. Live your life so that when you die, you are the one who is smiling and everyone around you is crying.[共5题](1) You should rely on someone who makes you smile_______________.(A) because a smile can make your dark time easier.(B) because a smile is bright .(C) because you have nothing.(D) because you can believe someone正确答案：A(2) What does the word “assurance”mean in the first paragraph?(A) return(B) promise(C) maintain(D) storage正确答案：B(3) In the third paragraph, “Always put yourself in other’s shoes”means_______________.(A) you should try other’s shoes before you buy it.(B) you should make yourself small enough.(C) you should consider from another person’s aspect.(D) None of the above.正确答案：C(4) If you are the one who is smiling and everyone around you is crying when you die, you are(A) Satisfied(B) Upset(C) Sad(D) Indifferent(冷漠的)正确答案：A(5) What has been mentioned in the passage?(A) to tell us not to demand too much(B) to warn us not to believe in appearance(C) to consider other people and learn to forgive(D) all of the above正确答案：D44.There are two types of twins: identical and non-identical twins. Identical twins are formed from a single egg in mother’s body which divides to form two separate babies. Identical twins look the same and are often dressed by their parents in clothes of the same colors. It is often difficult to tell identical twins from each other, even when they are standing side by side. Non-identical twins come into being when the mother produces two separated eggs at the same time, both of which grow to form babies. In this case the twins look like normal brothers and sisters and are easy to tell one from the other.In the 1970s and 1980s a scientist did some research into twins. He invited many pairs of identical twins to university and asked them to take part in a week of tests. He was particularly interested in adopted (收养) twins who had been separated at birth. He would give the twins different kinds of tests to study their speed of thinking, their speech, their memory, the ways they saw and heard different things, and so on. Time and time again he found separated twins who preferred clothes of the same color, used the same kind of shaving soap, wore the same shaped square glasses and the same colored socks.There is a third type of twins, but it is a very unusual one. Twins who are joined together at birth are known in western countries as Siamese twins.[共5题](1) It is difficult to tell identical twins because ____________.(A) they are dressed in the same clothes(B) they are dressed in the same color(C) they are very alike(D) they are standing side by side正确答案：C(2) If the twins are easy to tell from each other, they are ____________.(A) very probably non-identical twins(B) surely non-identical twins(C) surely identical twins(D) always a brother and a sister正确答案：A(3) Which of the following is NOT true according to this passage?(A) In the 1970s and 1980s a scientist did some research into the two main types of twins.(B) In the week of tests, he tested their speed of thinking, their speech, their memory and some other things.(C) There were twins who had been separated from each other as soon as they were born.(D) Very often, separated twins were found to choose things of the same kind, the same shape and the same color.正确答案：A(4) According to the passage, how many types of twins are there actually ?(A) one(B) two(C) three(D) four正确答案：C(5) This passage mainly tells us ____________.(A) the main types of twins(B) what has been found out about twins(C) how twins are formed(D) how a scientist studied twins正确答案：B45.The private automobile (私家车) has long played an important role in the United States. In fact, it has become a necessary and important part of the American way of life. In 1986, sixty-nine percent of American families owned at least one car, and thirty-eight percent had more than one. By giving workers rapid transportation, the automobile has freed them from having to live near their place of work. This has encouraged the growth of the cities, but it has also led to traffic problems.For farm families the automobile is very helpful. It has made it possible for them to travel to town very often for business and for pleasure, and also to transport their children to distant schools.Family life has been affected (影响) in various way. The car helps to keep families together when it is used for picnics, outings, and other shared experiences. However, when teenage children have the use of the car, their parents can’t keep an eye on them. There is a great danger if the driver has been drinking alcohol or taking drugs, or showing off by speeding or breakingdown traffic laws. Mothers of victims (受害者) of such accidents have formed an organization called MADD(Mothers Against Drunk Driving). These women want to prevent further tragedies (悲剧). They have worked to encourage the government to limit the youngest drinking age. Students have formed a similar organization, SADD (Students Against Drunk Driving) and are spreading the same message among their friends.For many Americans the automobile is a necessity. But for some, it is also a mark of social position and for young people, a sigh of becoming an adult. Altogether, cars mean very much to Americans.[共5题](1) Which of the following is NOT mentioned in the text?(A) Cars have encouraged the growth of the cities.(B) Cars can bring families together when they go for picnics.(C) Cars have enabled people to live far from their place of work.(D) Cars help city families to transport their children to faraway schools.正确答案：D(2) What has been done to deal with the problem of drunk driving?(A) Parents have paid more attention to their children.(B) Some organizations have been set up against drunk drinking.(C) Mothers have tried to persuade their children not to drink alcohol.(D) University students have asked the government to solve the problem.正确答案：B(3) We can infer from the text that ___________ in America.(A) it will be more difficult for people to get new cars(B) parents will not allow their children to have their own cars(C) the government will encourage people to use public transportation(D) cars will still be popular though they have cause many problems正确答案：D(4) “By giving workers rapid transportation, the automobile has freed them from having to live near their place of work.”means ___________.(A) With the help of the automobile, workers needn’t live close to their work places.(B) Automobiles make workers transport rapidly.(C) Automobiles make workers feel free to live in their place.(D) With the rapid transportation, workers have to live near their work places.正确答案：A(5) In the text, the author is focusing on___________.(A) the advantages of the automobile(B) the disadvantages of the automobile(C) the advantages and disadvantages of the automobile(D) the future of the automobile正确答案：C46. __(1)__ months later, the wife came to the husband with a proposal, “I read in a magazine, a while ago, __(2)__ how we can strengthen our marriage,”she offered.“Each of us will write a list of the things that we find a bit annoying with __(3)__ person.

大学英语IV 西南交大离线作业

1)介绍你的春节计划；
2)说明其中一项活动。
My Plan for the Spring Festival
Spring Festival is a traditional day for the Chinese people to get together besides The Mid-Autumn Day.For this reason many people rush home wherever they are.However far they are and however busy they are, they try to go home.I am one of those who hate it because after one festival, I become one year older.Another reason is that there are many more ceremonies before or after the festival.
On the other hand, some people don’t agree with those people mentioned above. They quote the old saying “Health is above wealth” to prove their idea. A strong person can do almost anything as long as he tries hard.
My Ideal Job
Every person has his own ideal job. Some people wish to be doctors, while others want to be teachers and so on.

This is the first time the two species have been sorted separately. In the past, elephants were mostly considered as either Asian elephants or African elephants. Forest and savanna elephants were typically classified as subspecies of African elephants.The African forest elephant is now listed as critically endangered and the African savanna elephant as endangered. The number of African forest elephants fell by more than 86% over a 31 -year assessment period. The population of African savanna elephants dropped by at least 60% over the last 50 years, according to the IUCN, which tracks the assessment risk of the world's animals. Africa currently has an estimated 415,000 elephants, counting the two species together.Both elephant species experienced significant population decreases because of poaching. Although it peaked in 2011, illegal hunting still happens and continues to threaten elephant populations. African elephants also face continued habitat loss as their land isconvertedfor agriculture or other uses.There is some good conservation news, the IUCN points out. Anti-poaching measures, combined with better land use planning to support better human-wildlife relationships, have helped conservation efforts. Some forest elephant population figures have stabilized in well-managed areas in Gabon and the Republic of Congo and savanna population figures have remained stable or have been growing, particularly in the Kavango-Zambezi Transfrontier Conservation Area in southern Africa.But with constant demand for ivory and increasing human pressures on Africa's wild lands, concern for Africa's elephants is high, and the need to creatively conserve and wisely manage these animals and their habitats is more severe than ever.4. What can be inferred from the new report about African elephants?A. They are divided into three kinds.B. They are dying out.C. Their threat is mainly from poaching.D. Their population has grown in Africa.5. What does the author mainly tell us in Paragraph 3?A. The detailed number of African elephants.B. The similarities of African elephants.C. The different types of African elephants.D. The present situation of African elephants.6. What does the underlined word "converted" in Paragraph 4 probably mean?A. Expanded.B. Protected.C. Transformed.D. Forbidden.7. What's the authors attitude to the present situation of African elephants?A. Hopeless.B. Optimistic.C. Uncertain.D. Worried.CSome years ago a young man applied to a large United States optical firm for a job as a lens designer. He apologized for lack of training, but on announcing that he owned two copies of the classic Conrady's Applied Optics and Optical Design, one for his office and a second for his bedside table, he was hired on the spot. Perhaps the story will be repeated some day with Buchdahl's Introduction to Hamiltonian Optics as a similar certificate of qualification.Hamiltonian theory describes with powerful generality the overall properties of optical systems considered as ‘black boxes’, although it does not describe the detailed structure needed to construct the systems and achieve these properties. Buchdahl's book is therefore on the subject of geometrical optics, but it is not about how to design lenses. It is, however a compact comprehensive account of the fundamentals of the theory written with the lens designer's needs very much in mind. Every lens designer worth his salt has at some time in his career attempted to apply the broad concepts of Hamiltonian optics to the solutions of practical problems. Success has been sufficiently rare that the theory, as such, has made little direct contribution to techniques for optical instrument design. The failures have been frustrating because of the obvious fundamental power of the theory and because of its conceptual elegance. The indirect effects have been large, however, both in contributing to an understanding of fundamental principles that govern the overall behavior of optical systems and in pointing the way to other, more practical, theoretical approaches.Buchdahl approaches the subject not only as a capable mathematical physicist, but as one who with a knowledge of practical optics has made a significant contribution to geometrical optical theory. Buchdahl's approach has, over the last decade, had a major impact on modern lens design with computers. Thus, he brings to this exposition of Hamiltonian optics a familiarity with practical optics not usually found in authors on this subject.The author claims his book to be non-mathematical, and indeed it might be so viewed by a professional mathematician. From the point of view of many physicists and engineers, it will appear to be quite mathematical. Moreover, this is a tightly written book. The subject matter is developed with precision, and the author expects the reader, at very point, to be master of the preceding exposition.8. Hamiltonian theory met with failures as a result of ______.A. newer finding related to the wave particle nature of lightB. very complicated concepts too difficult to understand by most lens designersC. too much mathematical detail in the theoryD. not enough practical information offered by the theory to allow for use by lens crafters9. The author of this passage implies that Introduction to Hamiltonian Optics is necessary to ______.A. the students who are major in mathematical geometryB. those who want to grasp the basic principles of optical systemsC. the lens designers who look for instructions on practical designsD. those who are interested in physics10. The article points out that the great benefits of Hamiltonian optics have been found is ______.A. indirect ways of learning mathematicsB. a fundamental power within the theoryC. the conceptual elegance of the theoryD. the practical applications of the theory in finding new approaches to old problems11. This passage is probably excerpted from ______.A. a review of a bookB. a chemistry textbookC. an optician's essayD. a general science textD“Heavy hearts, like heavy clouds in the sky, are best relieved by the letting of a little water, the French writer Antoine de Rivarol wrote. This love letter to the cleansing beauty of a good cry is a comforting thought at atime when the continuing stress of the COVID-19 has added heaviness to each of our lives.Scientifically, de Rivarol's poetic image doesn't, if you'll forgive the words used in the poem, hold water. There's limited research on crying, partly because of the difficulty of copying the behavior of real crying in a lab. But even within the previous studies, there's little evidence to suggest that crying provides a physiological cleansing of poisons in people's body.Psychologists believe the relief of a good cry connects with a different emotional process. “It seems that crying occurs just after the peak of the emotional experience, and crying is associated with this return to homeostasis: the process of maintaining a stable psychological state,” said Lauren Bylsma. He also said holding back tears can have negative physical consequences, including headaches and muscle tension. Such restriction can also limit our experiences of joy, gratitude and other positive emotions if we avoid acknowledging our feelings.For me crying has been easier said than done during the COVID-19. Psychologists say it's normal to feel stopped up by the stresses of the past year. We should find opportunities to release and process our emotions.Watching a tear-jerking movie, having an emotional conversation with a close friend, and writing in a journal are healthy ways toelicita cry. Physical activity like light-footed walking or even dancing can also signal our bodies to release some emotional tightness. We can then open up to the flow of feelings that leave us feeling lighter and refreshed—like a clear sky after a soaking rain.12. What is the weakness of the studies ever clone on crying?A. They were clone in a laboratory setting.B. They cared little about different forms of crying.C. They were always concentrated on people's daily life.D. They showed little about the positive physical effect of crying.13. What is the function of crying according to Lauren Bylsma?A. Curing people of their diseases.B. Keeping emotionally balanced.C. Producing negative mental results.D. Expanding people's experience of joy.14. What does the underlined word “elicit” in the last paragraph mean?A. Produce.B. Postpone.C. Control.D. Repeat.15. What are people advised to do according to the text?A. Learn to hold back their tears wisely.B. Share their emotion with their colleagues.C. Have a good cry when necessary.D. Try to avoid admitting our feelings.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。

My wallet was gone. And I could only have left it one place: the G9 bus, from which I had gotten off minutes earlier and which was now speeding to some stops. The moment of realizing it was gone was followed by mental math. How much time and money would it cost to replace the credit cards, the driver's license, the expensive lipstick ($ 55!).Two hours after I was back at my house, I heard a knock on the door. My husband answered while I sat in the dining room on the phone with a credit card company. "Does Jennifer live here?" I heard someone say. In her hand was my wallet, without a penny missing. She left before I could offer my gratitude to her.After I posted the story, I heard from her boyfriend, who identified the good citizen as Erin Ball, a 26-year-old girl working for a trade organization.Once I figured out her, I called to thank her. She said she spotted my wallet and thought that it's more dangerous to go to a stranger's house than leaving the wallet with the driver, but she still decided to take the chance. "If I were in that situation, I would want someone to try to find me," she said. Ball doesn't find her actions particularly excellent. She added, "It's not hard to do small things for people."After Ball found my wallet, she decided to post a picture of my driver's license online before going to my house, trying to see if anyone knew me. No sooner had she left my doorstep than I got emails from two neighborswho recognized my face, both offering to help me find my missing property.Ball found my house on a bitterly cold night,for which I was extremely grateful. Looking back, I'm not surprised someone had wanted to help a stranger. A warm current of honesty and harmony is running through this town.4. What do we know about the author according to paragraph 1?A. She missed the G9 bus.B. She paid for her bananas.C. She replaced the credit cards.D. She found she had left her wallet on the bus.5.

Which of the following best describes Erin Ball?A. Humorous and kind.B. Generous and demanding.C. Honest and warm-hearted.D. Caring and outgoing.CTrees are “social creature” that communicate with each other in cooperative ways that hold lessons for humans, too, ecologist Suzanne Simard says. Simard grew up in Canadian forests as a child of loggers before becoming an ecologist. She's now a professor of forest ecology at theUniversityofBritish Columbia.Trees are linked to neighboring trees by a network of fungi below the surface of the earth that resembles the nervous networks in the brain, she explains. In one study, Simard watched as a Douglas fir tree that had beeninjured by insects appeared to send chemical warning signals to a pine nearby. The pine tree then produced defense enzymes to protect against the insect.“This was a breakthrough,” Simard says. The trees were sharing “information that actually is important to the health of the whole forest.”In addition to warning each other of danger, Simard says that trees have been known to share nutrients at critical times to keep each other healthy. She says the trees in a forest are often linked to each other via an older tree she calls a “mother” or “hub” tree.“In connecting with all the trees of different ages, the mother trees can actually ease the growth of these young trees,” she says. “The young trees will link into the network of the old trees and benefit from that huge resource capacity. And the old trees would also pass a little bit of carbon and nutrients and water to the young trees, at crucial times in their lives, that actually help them survive.”The study of trees took on a new resonance for Simard when she suffered from breast cancer. During her treatment, she learned that one of the medicines she relied on was actually obtained from what some trees produce for their own mutual defense. She explains her research on cooperation in the forest, and shares her personal story in the new bookFinding the Mother Tree: Discovering the Wisdom of theForest.8. How could a Douglas fir tree send chemical warning signals to a pine nearby?A. By an underground network of fungi.B. By the nervous networks in the brain.C. By making cooperation with each other.D. By holding lessons to it as human beings.9. According to Simard, what was a breakthrough?A. Simard was-brought up in Canadian forests.B. She became a professor of forest ecology.C. The pine tree produced defense enzymes.D. Vital information was shared among trees.10. What helped Simard understand trees further?A. Her rich knowledge of trees.B. Her childhood in the forest.C. Her medicine gained from trees.D. Her research on cooperation.11. In Simard's book we may discover the wisdom of the forest except .A. communicating cooperativelyB. warning each other of dangerC. sharing nutrientsat critical timesD. sacrificing mother trees for survivalDIf you ever get the impression that your dog can "tell" whether you look delighted or annoyed, you may be onto something. Dogs may indeed be able to distinguish between happy and angry human faces, according to a new studyResearchers trained a group of 11 dogs to distinguish between images(图像)of the same person making either a happy or an angry face. During the training stage, each dog was shown only the upper half or the lower half of the person's face. The researchers then tested the dogs' ability to distinguish between human facial expressions by showing them the other half of the person's face on images totally different from the ones used in training. The researchers found that the dogs were able to pick the angry or happy face by touching a picture of it with their noses more often than one would expect by random chance.The study showed the animals had figured out how to apply what they learned about human faces during training to new faces in the testing stage. "We can rule out that the dogs simply distinguish between the pictures based on a simple cue, such as the sight of teeth," said study author Corsin Muller. "Instead, our results suggest that the successful dogs realized that a smiling mouth means the same thing as smiling eyes, and the same rule applies to an angry mouth having the same meaning as angry eyes.""With our study, we think we can now confidently conclude that at least some dogs can distinguish human facial expressions," Muller toldLive Science.At this point, it is not clear why dogs seem to be equipped with the ability to recognize different facial expressions in humans. "To us, the most likely explanation appears to be that the basis lies in their living with humans, which gives them a lot of exposure to human facial expressions and this exposure has provided them with many chances to learn to distinguish between them." Muller said.12. The new study focused on whether dogs can_________.A. distinguish shapesB. make sense of human facesC. feel happy or angryD. communicate with each other13. What can we learn about the study from paragraph 2?A. Researchers tested the dogs in random order.B. Diverse methods were adopted during training.C. Pictures used in the two stages were differentD. The dogs were photographed before the lest.14. What is the last paragraph mainly about?A. A suggestion for future studies.B. A possible reason for the study findings.C. A major limitation of the studyD. An explanation of the research method.15. In which section is the text most likely to be found in a newspaper ?A. EntertainmentB. EconomyC. ScienceD.

TheThree-Gorge Tribe scenic spot.BLarry was on another of his underwater expeditions(探险)but this time, it was different. He decided to take his daughter along with him. She was only ten years old. This would be her first trip with her father on what he had always been famous for.Larry first began diving when he was his daughter’s age. Similarly, his father had taken him along on one of his expeditions. Since then, he had never looked back. Larry started out by renting diving suits from the small diving shop just along the shore. He had hated them. They were either too big or too small. Then, there was the instructor. He gave him a short lesson before allowing him into the water with his father. He had made an exception. Larry would never have been able to go down without at least five hours of theory and another similar number of hours on practical lessons with a guide. Children of his age were not even allowed to dive.After the first expedition, Larry’s later diving adventures only got better and better. There was never a dull moment. In his black and blue suit and with an oxygen tank fastened on his back, Larry dived from boats into the middle of the ocean. Dangerous areas did not prevent him from continuing his search. Sometimes, he was limited to a cage underwater but that did not bother him. At least, he was still able to take photographs of the underwater creatures.Larry’s first expedition without his father was in the Cayman Islands. There were numerous diving spots in the area and Larry was determined to visit all of them .Fortunately for him, a man offered to take him around the different spots for rry didn’t even know what the time was, how many spots he dived into or how many photographs he had taken.The diving spots afforded such a wide range of fish and sea creatures that Larry sawmore than thirty varieties of creatures.Larry looked at his daughter. She looked as excited as he had been when he was her age. He hoped she would be able to continue the family tradition. Already, she looked like she was much braver than had been then. This was the key to a successful underwater expedition.4. In what way was this expedition different for Larry?A. His daughter had grown up.B. He had become a famous diver.C. His father would dive with him.D. His daughter would dive with him.5. What can be inferred from Paragraph 2?A. Larry had some special right.B. Larry liked the rented diving suits.C. Divers had to buy diving equipment.D. Ten-year-old children were permitted to dive.6. What can be learned from the underlined sentence?A. Larry didn’t wear a watch.B. Larry was not good at math.C. Larry had a poor memory.D. Larry enjoyed the adventure.7. What did Larry expect his daughter to do?A. Become a successful diver.B. Make a good diving guide.C. Take a lot of photo underwater.D. Have longer hours of training.CThe United Nations Educational, Scientific and Cultural Organization (UNESCO) included on December 17, 2020 China's Tai Chi on the RepresentativeList 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, manyyoung 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 is Competing against Yoga.C. Tai Chi Has Regained populate Globally.D. Opinions Greatly Differ on Tai Chi and Yoga.DWe all use different ways to remember ideas, facts and things we need to store. Remembering is an extremely important part of our learning experience. Information process, storage and recall encourage purposeful learning.But the brain doesn’t store everything we want or need for future use. It makes choices and tends to remember information that forms a memorable pattern. Things you learned recently can be particularly difficult to remember because they haven’t taken root in your mind.“Forgetting allows us to remember what is really important to our survival. We forget much of what we read, watch, and think directly every day.” writes John Medina in his book, Brain Rules.How do you avoid losing 90%of what you’ve learned? An inspiring writer and speaker Zig Ziglar once said: “Repetition is the mother of learning, the father of action, which makes it the architect of accomplishment.”Repetition has been a remembering skill for ages. When you hear or read something once，you don’t really learn it-at least not well enough to store the new information for long. The right kind of repetition can do wonders for your memory. People learn or remember better by repeating things or getting exposed to information many times. Othersrepeat particular steps or processes deliberately a number of times or even years to become better at certain skills.Daniel Coyle explains in his book, The Little Book of Talent:“...closing the book and writing a summary, even short ones, forces you to figure out the key points, process and organize those ideas so they make sense, and write them on the page. When you pick it back up weeks later, reread all of your notes or highlights to strengthen the ideas even further.”People learn by repeating things. Better learning is a repetition process. Every time we repetitively access something we already know, we increase the memory’s stored value.12. Which of the following can be inferred from the passage?A. The brain tends to store 90% of the things we learn.B. The fresher the information isthe easier to remember.C. Thinking is more important than remembering in study.D. The brain tends to choose and keep what it thinks important.13. How does the writer prove his opinion?A.By giving examples.B. By listing numbers.C. By borrowing words of experts.D. By providing scientific finding.14. What does Daniel Coyle want to say in his book?A. You can’t pay too much attention to repetition.B. Summarizing is a very effective learning tool.C. Forgetting forces human brain to make choices.D. Regular repetition helps to form good habits.15. Which do you think is the best title of the passage?A. How the Brain WorksB. Reading for MoreC. Fighting Against ForgettingD. Repeat to Remember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。
