And, with the support of his family and teachers, he took that love and helped change the world for billions of people, when he invented the modem video game cartridge.Both of Jerry's parents supported his love of science and invention. His father, a longshoreman, was a science fan and encouraged Jerry to always experiment with things. Jerry's first-grade teacher helped encourage him on his path to be someone influential similar to George Washington Carver, a great AfricanAmerican inventor. His first love in school was chemistry but he ended up liking electronics（电子学）even more.He earned an amateur ham radio license at age 13 and built his own radio station in his room, with an antenna hanging out of his window! Jerry earned money from fixing television sets, visiting people's homes for inhouse repair, and also working at local electronics stores. Jerry also made walkie-talkies and sold them to other kids. He spent many Saturdays at an electronics store that had all of the parts he needed for his inventions. He would use his small allowance and money he earned to buy parts to help fuel his inventions.When he was a young adult, Jerry joined Fairchild Semiconductor as an engineer. During this time, he created his own video arcade game（街机游戏），Demolition Derby, in his garage.A few years later, Jerry was asked to work on a secret project. Not even his boss was allowed to know what he was doing! What it turned out to be was that he was designing the Fairchild Channel F video gameconsole（游戏控制器）and leading the team that invented the video game cartridge. This was the first of its kind and enabled kids around the world to affordably play video games at home.Just like with automobiles，many advances have occurred since the inventionof video games.

Before Jerry's secret project, playing video games at home was_____.A. expensiveB. harmfulC. commonD. tiring6. What does the author mainly tell us in the last paragraph?A. Jerry Lawson and his team can be more skillful.B. Jerry Lawson is important to the game industry.C.Many advances have taken place in the automobile industry.D. Video games are now the most popular form of entertainment.7. What can be the best title for the text?A. Video Gaming-An Important IndustryB. Game Console-Key to Home Video GamesC. Jerry Lawson-Father of Modern GamingD. Support and Encouragement-Necessary for SuccessCThe 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.8. 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 mistakes9. 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 bleeding10. What does the underlined word ''fallout'' in Paragraph 3 probably mean?A. ResultB. BenefitC. DifferenceD. Absence11. 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 directionsDOne of the most popular street food found inChinais no doubt the barbecue. A new program, called ChineseBarbecue, tells the story of this popular food cooked over hot coals on just about every street corner in cities and towns across the country. Barbecued meat is an important part of people’s nightlife.Shown on June 20, the program has had more than 25 million clicks on the video site . To find the most popular barbecue stalls (摊位), the production team travelled to more than 500 locations in 30 cities across the country. Some viewers compare Chinese Barbecue to Midnight Diner, a Japanese TV program telling stories from late night informal Japanese bars.“I’m happy to hear this comparison because Midnight Diner is a good program, and we share the same topic― night food,” Chinese Barbecue’s director Chen Yingjie said. “However, they are quite different.” He said that Midnight Diner focused more on food itself, though there was someconversation while people were eating. However, the night food scene of Chinese people means joy and a more lively atmosphere. People eating these barbecue snacks develop a feeling of connection, which can be a cure for loneliness.The barbecue, regarded as the most ordinary and common night street snack, is different from home-made food by mothers as that is a symbol of family and kinship. The barbecue is where you go to become connected to people in society. And unlike official business lunches, during which people are rather polite, the barbecue lets people relax with old friends and new friends, leaving a lasting impression of friendship.The world, as a whole, holds deep-rooted good feelings toward the barbecue, either for the taste or the warmth produced by fire. “What we should do is to present the Chinese barbecue just the way it is because with its special ingredients(食材)，ways of cooking and more importantly, the special environment and people, the world will recognize it and might fall in love with it just as we do.” said Chen.12. What do we know about Chinese Barbecue?A. It has been becoming very popular on the Internet.B. It is thought highly of by most of the foreign tourists.C. It mainly talks about the most famous Chinese food.D. It shows the color1 ful nightlife in large cities ofChina.13. In which way was Chinese Barbecue different from Midnight Diner?A. It showed more kinds of food.B. It focused more on the diners.C. It showed the eating habits.D. It was less popular than Midnight Diner.14. What is Paragraph 4 mainly about?A. The importance of the barbecue to family.B. The influence of the barbecue on people’s manners.C. The influence of the barbecue on people’s lifestyle.D. The role of the barbecue in people’s relationship.15. Why did Chen Yingjie choose the barbecue as the topic of the series?A. To show the feature of Chinese food.B. To research a special way of cooking.C. To help the world understandChina.D. To introduce the history of the barbecue.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。

No wonder co-working spaces are becoming so popular: they permit self-employed individuals to feel like they are part of all office environment, while making them get some work done too. But renting a co-working space does cost money.Now a Swedish project is aiming to change that by turning people’s under-used homes into temporary co-working spaces, available to freelancers for free. Hoffice was started by freelancers Christofer Gradin Franzen and Johline Zandra about a year ago in Stockholm when they invited a few people into their home office to work together. It was a great success, and the project has since spread to a number of cities in Europe, North and South America, Australia, India and Japan. Anyone can sign up and offer their home space as a free co-working space, or go find a Hoffice near them.On a Hoffice day, everyone arrives and starts work at a certain hour. After 45 minutes, everyone gets up to take a break, stretch, do qigong or yoga for 10 to 15 minutes. Afterwards, people can gather around again, and re-state their intentions and goals for the rest of the work day, as a way to motivate each other. Meals can be eaten together at a certain hour, potluck-style(家常饭)or by bringing your own lunch.This process creates an encouraging and supportive work environment. As some freelancers describe, “By working at Hoffice, we give ourselves and each other the gift to spend our days in a social working environment, wherewe are extremely productive without ignoring our other human needs. We also make sure to give us and each other what we need to feel calm, happy, inspired and creative during the worki ng day. ”So Hoffice is not just about sharing space；it's also about a free exchange of ideas. And perhaps the best thing is that Hoffices are free to use.4. Hoffice was started to________.A. change people’s attitude to workB. encourage people to be more socialC. improve people’s working conditionsD. provide a co-working space for free5. What’s the main idea of Paragraph 3？A. How people respond to Hoffice.B. How a Hoffice day works.C. What people share at Hoffice.D. What Hoffice means to people.6. Some freelancers’descriptions of Hoffice suggest that they________.A. benefit a lot from the working styleB. work longer than beforeC. expect more people to join themD. can’t be separated from each other7. What do we know about Hoffice according to the text?A. It is becoming increasingly popular.B. It has been around for quite a few years.C. It has created many new job opportunities.D. It is suitable for people from all walks of life.3.Billboard Music Awards of the Year 2015 goes to Taylor Swift, a singer-songwriter, who has shaped and inspired the American music industry with her success.When T aylor Swift first came to public notice, she was a 17-year-old newcomer who loved singing to her own guitar. She was far more enthusiastic than skilled, but apparently threw spark of superb talent.Four years later, Swift has become a multi-awards winner, with the biggest selling albums. For her consummate performance, Taylor Swift wasnamed Billboard magazine’s woman in 2011. She is the youngest artist to receive honors and several Billboard Music Awards, among them Top Country Album for the five-time platinum (白金) selling Speak Now, her third album that was released that year.“Taylor has shown the power of good songwriting with music of styles.”said Bill Werde, Billboard’s editorial director, “And at such a young age, Taylor has already made a major impact on music and has been an unbelievable role model for promising artists and young woman everywhere.”Swift is used to breaking chart records and winning honors since her career started. She followed that up in 2008 with Fearless, which established her as a skilled songwriter with several hits, including Love Story, You Belong With Me and White Horse.Not surprisingly, the 6-time platinum Fearless is the most awarded album in country music history in the US and her overall worldwide sales now reach 20 million albums and 40 million songs downloads. Swift has spent the past year on the Speak NOW World Tour in support of her third album, and now she’s getting ready to go further.According to a recent interview with The New Yorker magazine, Swift has so far written about 10 songs for a 2016 album. She said the new album is about feelings of growing up and becoming an adult.“They’re sad if I'm being honest.” Swift told The New Yorker. “They’re about my heartbreaks and my moving on. But more importantly, they are about achieving contentment. You’re not always going to be ridiculously happy as you grow up. ”8. As a newcomer in the show business, Taylor Swift was considered to be_______.A. a skilled songwriterB. an outstanding artistC. an energetic directorD. a promising talent9. The underlined word “consummate” in Paragraph 3 can best be replaced by______.A. confidentB. professionalC. excellentD. different10.What can we learn from the passage？A.

Swift has gained Billboard magazine’s woman twice.11. Which of the following can be the best title of the passage？A. A Rising Music GeniusB. Taylor’s Heartbreaks in GrowthC. An Interview with Taylor SwiftD. Billboard Music Awards in America4.If asked if space exploration should continue, most Americans would give an immediate response either in favor of continuing or in favor of ending space exploration. A common response would be that space exploration is a waste of money. An average American, uneducated on the subject, might believe that the government is wasting billions of dollars on the research that has no value. Someone strange to the subject might say that a space shuttle goes up once in a while and that is about all that happens. Research is ongoing and continues when there are no shuttles being launched. This also costs the government money. Does the extreme cost of space exploration make sense?One argument is that the government is wasting money on the research not being used on Earth. Actually, the money goes to workers and scientists that support National Aeronautics and Space Administration(NASN) missions, and goes to major companies that play important roles in major sectors of the US economy. Boeing is a partner of NASA for aircraft, the same company that makes commercial aircraft for the airline industry.Another benefit to continuing space exploration is the many technologies it provides., The artificial (人造的) heart resulted from experiments on the space shuttle. The handheld Jaws of Life used to save victims from car accidents resulted from the system used to separate the space shuttle from its booster rockets. Insulation (隔热板) in homes that keeps them warm and energy efficient is based on the technology used to insulate the space shuttle.There are direct benefits to the economy provided by NASA missions as well as those technologies. These advances are found in food, building materials, medical procedures and the vehicles we drive. While it can be proven that billions of dollars that could be used elsewhere is being spent on space exploration, the benefits it provides outweigh the terrible aspects. As a matter of fact, the money spent helps to improve the quality of our lives.12. How is Paragraph 2 mainly developed?A. By offering analyses.B. By making comparisons.C. By giving some examples.D. By presenting research findings.13. The function of Jaws of Life is to_____.A. save people from traffic accidents.B. do experiments on the space shuttleC. keep houses warm and energy efficientD. separate the space shuttle from its booster rockets.14. In the author’s opinion, space exploration______.A. has changed our life completelyB. costs too much of our timeC. benefits us in many waysD. has nothing to do with us15. What would be the best title for the text?A. Benefits of space explorationB. Is space exploration worth the cost?C. How to make space exploration affordableD. Missions of the NASA space shuttle program二、未分类(共2题)munication has always been one of the basic keys to success. They say great public speakers are born and not made, but there are always some tricks of the trade which will help you in becoming a great orator. 16 Read, Study and LearnReading and studying helps you to learn different words and ways to convey your idea.

It’s because he had that enthusiasm which would spread to other people in a heartbeat. So you must show enthusiasm in what you are speaking about, or it will seem that even you are uninterested in what you have to say.Welcome Questions20 Allow your audience some time to ask you questions.

2020-2021学年陕西安康中学高三英语第三次联考试题及参考答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AIn his 402nd anniversary year, Shakespeare is still rightly celebrated as a great language master and writer. But he was not the only great master of play writing to die in 1616, and he is certainly not the only writer to have left a lasting influence on theater.While less known worldwide, Tang Xianzu is considered one of Chinas greatest playwrights and is highly spoken of in that country of ancient literary and dramatic traditions.Tang was born in 1550 inLinchuan,Jiangxiprovince. Unlike Shakespeare's large body of plays,poems and sonnets (十四行诗), Tang wrote only four major plays: The Purple Hairpin, Peony Pavilion (《牡丹亭》), A Dream under the Southern bough, and Dream of Handan. The latter three were constructed around a dream narrative, a way through which Tang unlocked the emotional dimension of human desires and ambitions and explored human nature beyond the social and political limits of that time.Similar to Shakespeare, Tang's success rode the wave of a renaissance (复兴) in theater as an artistic practice. As in Shakespeare'sEngland, Tang's works became hugely popular inChinatoo. During Tang'sChina, his plays were enjoyed performed, and changed. Kunqu Opera, a form of musical drama, spread from southernChinato the whole nation and became a symbol of Chinese culture. Combining northern tune and southern music, kunqu Opera was known for its poetic language, music, dance movements and gestures. Tang's works benefited greatly from the popularity of kunqu Opera, and his plays are considered classics of kunqu Opera.While Tang and Shakespeare lived in a world away from each other, there are many things they share in common, such e humanity of their drama, their heroic figures, their love for poetic language, a lasting popularity and the anniversary during which we still celebrate them.1. Why is Shakespeare mentioned in the first paragraph?A. To describe Shakespeare's anniversary.B. To introduce the existence of Tang Xianzu.C. To explain the importance of Shakespeare.D. To suggest the less popularity of Tang Xianzu.2. What's possibly one of the main theme of Tang's works?A. Social reality.B. Female dreams.C. Human emotions.D. Political environment.3. What does the author mainly tell us in Paragraph 4?A. The influence of Kunqu Opera on Tang's works.B. Tang's success in copying Shakespeare's styles.C. The way Kunqu Opera became a symbol of Chinese culture.D. Tang's popularity for his poetic language and music.BStarting at university or college can be a big challenge, especially if you’re living away from home for the first time. You arefaced with big questions such as, “Who’s going to do my washing?” “Who’s going to tidy my room?” And, most importantly, “How am I going to eat?” Yes, living on your own means cooking for yourself, and when you’re living a student lifestyle, this could be a recipe for disaster.Students, in the UK at least, often rely on generally available food such as baked beans or cheese on toast. And for the more adventurous, there’s “spag bol” — spaghetti bolognaise(肉酱意粉), that is, cooked spaghetti served with a ground beef and tomato sauce — a budget-friendly solution. If you make a huge pan of it, it can probably last you a whole week! Other low-cost options include jar sauces and oven pizzas.Recently, a British supermarket suggested that rose harissa paste, organic cider vinegar and Swiss bouillon powder were the important food materials needed for the “student cupboard”. But are these items considered essential and affordable for someone on a budget?As a matter of fact, living on a budget is certainly one barrier to eating a well-balanced diet. What’s more, some young people don’t know much about cooking, and for many young students, there are more fun things to go and do than just stay inside and cook. That’s where takeaways and microwave meals come in.What should a health-conscious student really have in his or her food cupboard? Jack Monroe, a food writer and campaigner, has words to say: baked beans, lemon juice, canned tomatoes and tomato ketchup, described as “salt, sugar, vinegar and tomato all in one handy squeezy bottle”. And should that not appeal, you can always wait till your next visit to your mum and dad for a square meal!4. What does the author indicate by “this could be a recipe for disaster”?A. Cooking is difficult for a student.B. Students must cook if they live alone.C. It is important to live independently.D. Learning to cook will cause disasters.5. What is the feature of “spag bol”?A. It is delicious.B. It is healthy.C. It saves money.D. It needs little skill.6. What is paragraph 4 mainly about?A. How well-balanced diets can be realized.B. How students can eat healthily with limited money.C. Why living on a budget is common among students.D Why students choose takeaways and microwave meals.7. Why does the author write the last paragraph?A. To advocate visiting parents.B. To offer some tips.C. To promote health consciousness.D. To introduce a writer.CThe 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.8. 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 mistakes9. 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 bleeding10. What does the underlined word ''fallout'' in Paragraph 3 probably mean?A. ResultB. BenefitC. DifferenceD. Absence11. 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 directionsDIf you travel inAthens, against popular belief, I would highly recommend saving the Acropolis for yoursecondday. As attractive as it is to head straight to the most famous building in the city, there are several reasons why you should hold off until later.Sunriseis the best time to see the ruins, and who wants to spend their first day in anew citywaking up at6 a.m.? On top of that, the Acropolis is going to make every other site inAthensless important in comparison, so I recommend not hitting it on your first day.We got to the southeast gate at 7：30, half an hour before it opened at 8. When the gate opened, we rushed to the hill. Our plan paid off because we had the whole complex to ourselves for five minutes. In this age of overtourism, getting to the greatness of the Acropolis with nobody else around felt special and excited.The Acropolis is the name given to the complex on top of the hill, and it’s made up of several buildings. There’s theTempleofAthena Nike, the Parthenon, the Old Temple of Athena, the Legendary Olive Tree of the Pandroseion, the Porch of the Caryatids at the Erechtheion... and on your way down, the Odeon of Herodes Atticus.Something that sounds boring but isn’t is theAcropolisMuseum, and I recommend spending a couple of hours there. As someone who is a museum-avoider, I listened to the recommendations of everyone who had been, and made myself go inside. And I loved it. The museum houses tons of sculptures unearthed from the Acropolis, and it was interesting to check them out.Head toSyntagma Squarenext to watch the changing of the guard. This takes place every hour on the hour, so try to time your visit perfectly. The guards wear fun clothes and make for interesting photos.12. The author suggests visiting the Acropolis on the second day so that ___________.A. it can save visitors a lot of timeB. it can save visitors from getting up earlyC. it can make for a better travel experienceD. it can give visitors a better understanding ofAthens13. How did the author feel when he ran to the top of the hill?A. Bored.B. Worried.C. Relaxed.D. Amazed.14. With what may the author agree about theAcropolisMuseum?A. It is so great that it should be visited last.B. It is enjoyable and worth visiting.C. It wastes a lot of time.D. It should be avoided.15. What is the purpose of the text?A. To provide some advice on visiting the Acropolis.B. To introduce the history of the Acropolis.C. To call on people to protect historic sites.D. To encourage people to travel around.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。
