2020-2021学年广州市第四十七中学天润校区高三英语月考试卷及答案
2020-2021学年广州市第四十七中学天润校区高三英语月考试卷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AYou might not expect it, but cows are a large source of the greenhouse gases that are driving climate change. Cows produce lots of methane by breaking down the grass, Now scientists have shown that the pollution from cows canbe reduced by adding a little seaweed to their food.Scientists first discovered that seaweed could help control methane from cows several years ago. But this work was done in a laboratory, there were many questions about whether the idea could work in real life.In the lab studies, the cows were given quite a bit of seaweed, and they would cause losing weight. That wasn't helpful, since cows are often sold by weight. It also wasn't clear if the seaweed would stop working if it was used for a longer period of time.Now, scientists from the University of California, Davis have answered several of these questions.The researchers studied 21 cows on a farm for about five months. They taught the cows to get their food from inside a special hood, which allowed the scientists to measure the methane that the cows were giving off. This time, they used a much smaller amount of seaweed, which they mixed with the cows' food.The results were surprisingly good. In some cases, the cows produced 82% less methane. The improvement depended on the kind of food the cows were given, but even the worst-polluting cows produced 33% less methane.Over the five months, the scientists didn't see any signs that the cows' stomachs were getting used to the seaweed and starting to produce more methane again.Another surprise came when they looked at the weight of the cows. The cows that were fed seaweed gained just as much weight as the other cows, but they didn't need as much food.But there are still some big problems with the idea of feeding cows seaweed. For one thing, there's notadequateseaweed to feed all of the cows in the world. So farmers would have to figure out a way to grow lots of seaweed.A bigger problem is that for most of their lives, cows live in fields, where they eat the grass. That means there's no chance to feed them seaweed every day. These problems need to be taken seriously if the world isgoing to avoid the worst effects of the climate crisis.Still, it's true that something as simple as feeding cows seaweed can help reduce some of the pollution causing the climate crisis.1. Why did the scientists do the experiment on the farm?A. To control the amount of seaweed.B. To record the weight cows gained.C. To confirm the effect of seaweed in real life.D. To measure the amount of seaweed cows ale.2. The underlined word “adequate” means ________ .A. commonB. specialC. lackingD. enough3. The passage is written to ________ .A. appeal to people not to raise the cowsB. encourage people to plant the seaweedC. remind people of controlling cows' weightD. call on people to take actions to reduce the pollutionBNot long after the first fitness magazine was published, a list probably followed soon after, ranking the best fitness equipment. This tradition has continued, with the implied message: usethisand exercise willbe yours.And that's part of the problem, says Dr. Lieberman, a professor of Harvard University. There isn't one “best” anything to achieve fitness. Besides, people understand exercise is good for them. Knowledge about exercise still doesn't motivate.Before you can answer why, it helps to look at history. Before the Industrial Revolution, people fetched water and walked up stairs because they had to. But then technology made life and work easier. Exercise has become something that people have to carve out time for. “It's a fundamental instinct to avoid physical activity when it's neither necessary nor rewarding,” he says.It would seem like being healthy would qualify as necessary, but a doctor's prescription to exercise “can make it like taking cod liver oil,” Lieberman says. “Sometimes it works, but more often than not, it doesn't. And it's still coming across as an order, and “not having a heart attack in five years is not an immediate reward,” says Dr. Beth Frates, assistant professor at Harvard Medical School.People might not want to exercise because it's never been enjoyable. Most of us probably have memories of gym class, not being picked for a team, or being in a fitness center that's filled with in-shape people. The majority don't feel excited. They feel that exercise isn't for them, but it can be. Coaching people in an empowering and motivating way can work much better than ordering someone to exercise. It starts with an expanded definition ofwhat counts as exercise, and an injection of what's rarely used to describe exercise, but is certainly allowed: namely, fun.4. What does the underlined “this” in paragraph 1 refer to?A. The magazine.B. The tradition.C. The equipment.D. The message.5. What can we infer about technology?A. It improves life quality.B. It saves people's time.C. It drives social progress.D. It makes exercise less likely.6. Why does the author mention “cod liver oil” in paragraph 4?A. To attach importance to health.B. To present a doctor's prescription.C. To explain exercise is considered inessential.D. To introduce the latest medical application.7. What is the main idea of the last paragraph?A. Exercise should be made more joyful.B. It's more fun to work out with others.C. We may encounter bad workout experiences.D. Orders work well to motivate people to exercise.CIn sportthe sexes are separate. Women and men do not run or swim in the same races. Women are less strong than men.That at least is what people say.Women are called the weaker sex, or, if men want to please them, the fair sex. But boys and girls are taught together at schools and universities. There are women who are famous Prime Ministers, scientists and writers. And women live longer than men. A European woman can expect to live until the age of 74, a man only until he is 68. Are women’s bodies really weaker?The fastest men can run a mile in under 4 minutes. The best women need 4.5 minutes. Women’s time is always slower than men’s, but some facts are a surprise. Some of the fastest women swimmers today are teenage girls. One of them swam 400 meters in 4 minutes 21.2 seconds when she was only 16. The first ‘Tartan’ in film was an Olympic swimmer, Johnny Weissmuller. His fastest 400 meters was 4 minutes 49.1 seconds, which is 37.9 seconds slower than a girl 50 years later! This does not mean that women are catching men up. Conditions are very different now and sport is much more serious. It is so serious that some women athletes are given hormoneinjections. At the Olympics a doctor has to check whether the women athletes are really women or not. It seems sad that sport has such problems. Life can be very complicated when there are two separate sexes!8. Women are called the weaker sex because _________.A. women do as much as menB. people think women are weaker than menC. sport is easier for men than for womenD. in sport the two sexes are always together9. Which of the following is true?A. Boys and girls study separately everywhere.B Women do not run or swim in races with men.C. Famous Prime Ministers are women.D. Men can expect to live longer than women in Europe.10. The underlined part “That at least is what people say” means people _________.A. say other things, tooB. don’t say this muchC. say this but may not think soD. only think this11. In this passage the author implies that _________.A. womenare weaker than men, but fasterB. women are slower than men, but strongerC. men are not always stronger and faster than womenD. men are faster and stronger than womenDDid you know that the average child has heard the word "no" over 20,000 times before they turn the age of three? Ironically, it is also around this time that children begin to develop enough personal character to refuse to obey. The "terrible twos" are categorized by a lack of understanding. Somewhere between three and four, children begin to acquire the skills to reason. It is during this time they watch how other children and adults reason. If we're not careful, the children will watch us model a world of "NOs".By the time a person turns eighteen, how many times have they been told no? I haven't found any studies that even attempted to track this statistic, but I'm sure if the number is 20,000 by three, then at eighteen that number has multiplied. You can do the math.Anyway, I think I know why we say no. We say no to protect. We say no to direct. We say no to stop potential confusion. However, do we sometimes say no just for the sake of saying no? Do we say no because we have internalized(内在化)all of the "NOs" we've heard over the years and we feel it is finally our time to say no to someone else?The internalized no can damage the growth process of dreams in infancy as quickly as it can weaken a three-year-old. And we wonder why we run intopeople with big, un-accomplished dreams who have a bit of a chip on their shoulder. They have to take on the 20,000 NOs. However, the thing that keeps them going is the possibility of the power of ONE YES! Just as it only takes one book to make a writer a Pulitzer Prize Winner, it only takes one word to change the course of your day. That word is YES!12. What do we know about two- year- olds?A. They understand well.B. They often say no to others.C. They think logically.D. They don't do all they're told.13. What effect does saying no have on children?A. They lose all their dreams.B. They aren't easy to succeed.C. They don't make mistakes.D. They never say yes to others.14. Which word best describes the author's attitude to a world of "NOs"?A. Tolerant.B. Disapproving.C.

Criticism from coaches, parents and other teammates, as well as pressure to win can create too much anxiety or stress for young athletes. Stress canbe physical, emotional, or psychological and research has indicated that it can lead to burnout. Burnout has been described as dropping or quitting of an activity that was at one time enjoyable.The early years of development are critical years for learning about oneself. The sport setting is one where valuable experiences can take place. Young athletes can, for example, learn how to cooperate with others, make friends, and gain other social skills that will be used throughout their lives. Coaches and parents should be aware, at all times, that their feedback to youngsters can greatly affect their children. Youngsters may take their parents and coaches’ criticisms to heart and find faults in themselves.Coaches and parents should also pay attention that youth sport participation does not become work for children. The outcome of the game should not be more important than the process of learning the sport and other life lessons. In today’s youth sport setting young athletes may be worrying more about who will win instead of enjoying themselves and the sport. Following a game many parents and coaches focus on the outcome and find faults with youngsters’ performances. Positive support should be provided regardless of the outcome. Research indicates that positive support motivates and has a greater effect on learning than criticism. Again, criticism can create high levels of stress, which can lead to burnout.4. An effective way to prevent the burnout of young athletes is_____________.A. to make sport less competitiveB. to increase their sense of successC. to reduce their mental stressD. to make sport more challenging5. According to the passage, sport is positive for young people in that_____________.A. it can help them learn more about societyB. it enables them to find faults in themselvesC. it can provide them with valuable experiencesD. it teaches them how to set realistic goals for themselves6. Many coaches and parents are in the habit of criticizing young athletes_____________.A. believing that criticism does good to their early developmentB. without realizing criticism may destroy their selfconfidenceC. in order to make them remember life’s lessonsD. so as to put more pressure on them7. According to the passage parents and coaches should_____________.A. pay more attention to letting children enjoy sportB. help children to win every gameC. train children to cope with stressD. enable children to understand the positive aspect of sportCIn recent years, with the development of technology, it is common to see robots into our homes in the form of toys and vacuums (吸尘器) without question. Children’s toys that rely on robotics for both entertainment and education are becoming more popular and more easily accessible. Robot vacuums, too, are so popular that the Roomba has even earned itself a name in popular television.A selection of other household wares can be purchased and owned for a reasonable cost, but they all look and perform like vacuums. Our domestic helpers are currently designed to vacuuming, mopping, sweeping and mowing.Of course the best known of these is the Roomba, but there is actually some competition amongst the autonomous vacuum manufacturers. Roomba, made by iRobot, now comes in several designs and has been through many versions of improvements. The basic model is just about $400, but there’s a more attractive version, complete with a wireless command center to control the robot from anywhere in the home. Samsung also has a vacuum, called the Smart Tango, which makes increased improvements on the Roomba by including brushes for cleaning corners. It’s possible that some of the less well-known vacuums might be even more exciting, like the Neato Robotics XV that takes on a square shape to better clean corners. Incremental (增值的) improvements arewhat drive the home robot industry.Now that domestic robots are becoming more popular, the near future should be exciting. If we are going to welcome robots into our lives and our homes, we should expect them to work for it, and work hard. It’s the dawn of the robot revolution, whether we like it or not, and it would be great to see that technology put to use in more innovative(创新的) ways.8. What does Roomba in the passage mean?A. A man’s name who has bought a domestic robot.B. A name of a big company who makes robots.C. A type of vacuum whose name is Roomba.D. A place where people can buy proper robots.9. The Smart Tango is different from other types in that ________.A. it has a wireless command centerB. it has brushes for cleaning cornersC. it is more famous and excitingD. it is driven without electricity10. What can we infer according to the last paragraph?A. Domestic robots will free us from housework.B. Domestic robots will become cheaper and cheaper.C. Domestic robots have brought environmental revolution.D. Domestic robots takes the lead in science and technology.11. What does the author intend to tell in the passage?A. Domestic robots are closely related to our daily life.B. It is interesting to see domestic robots at home.C. Domestic robots are too expensive for most people.D. It is convenient to buy a domestic robot.DIn order to help discover spoilage and reduce food waste for supermarkets and consumers, researchers have developed new low-cost, smart phone-linked, eco-friendly spoilage sensors for meat and fish packaging.One in threeUKconsumers throw away food just because it reaches the use-by date, but 60% of the £12.5 billion-worth of food we throw away each year is safe to eat.The researchers, whose findings were published in ACS Sensors, say the sensors could also eventually replace the use-by date—a widely used indicator of being fresh and eatable.The sensors cost two US cents each to make. Known as “paper-based electrical gas sensors (PEGS)”, theydetect spoilage gases like ammonia (a poisonous gas with a strong unpleasant smell) in meat and fish products. The information provided by the electronic nose is received by a smart phone, and then you can know whether the food is fresh and safe to eat.The Imperial College London researchers who developed PEGS made the sensors by printing carbon electrodes onto a special type of paper. The materials are eco-friendly and harmless, so they don’t damage the environment and are safe to use in food packaging. The sensors, combined with a tiny electronic system, then inform nearby mobile devices, which identify and understand the data about spoilage gases.Lead author Dr Firat Guder of Imperial’s Department of Bioengineering, said, “Although they’re designed to keep us safe, use-by dates can lead to eatable food being thrown away. They don’t always reflect its actual freshness. In fact, people often get sick from food-borne diseases due to poor storage, even when an item is within its use-by date.”“These sensors are cheap enough so we hope to see supermarkets using them within three years. Our goal is to use PEGS in food packaging to reduce unnecessary food waste.”The authors hope that PEGS could have applications beyond food processing, like sensing chemicals in agriculture, air quality, and detecting disease markers in breath like those involved in kidney disease.12. What is the function of PEGS according to the text?A. To improve the taste of foods.B. To improve the service of stores.C. To help supermarkets store foods.D. To help people test food freshness.13. What role does the smartphone play while PEGS are functioning?A. It acts as an electronic nose.B. It reads the data collected by PEGS.C. It helps print the gas sensors onto paper.D. It discovers the spoilage gases from foods.14. What does Dr. Firat Guder say about use-by dates?A. They are not completely reliable.B. They can help reduce food waste.C. They are based on scientific research.D. They are not accepted by the consumers.15. What does the author mainly talk about in the text?A. The process of researching spoilage sensors.B. A new technology in packaging to reduce food waste.C. The application of spoilage sensors beyond food processing.D. The influence of use-by dates on supermarkets and consumers.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。

2020年广州市第四十七中高三英语月考试题及答案解析第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AA brother and a sister have been reunited (重逢) after more than 60 years, thanks to a letter in the Welwynand Hatfield Times. For years John Hannant kept a photo of his long-lost sister, hoping they would meet again.Margery, the eldest of three children, had signed up with the Royal Air Force as part of the war effort, when John was still a baby.The family lost touch and as many years passed only a single letter gave a clue to her whereabouts (下落). The clue was enough for a WHT reader to recognize Margery and put the family back in touch.John, 67, said he had been searching for a long time and a friend suggested writing to the paper.“That’s the one that made it, the letter to the paper,” he said. “It’s like a dream that comes true. The last time we ever heard from Margery was in 1953 after the terrible floods. She wrote home to know if we were all right.My sister Dorothy wrote back, but Margery had moved again and never got the letter.”Having retired from his job as a gardener at Park House, Mr Hannant decided to take action.He and his wife Doreen traveled to Margery’s home in Chelwood Avenue, Hatfield, which she shares with her husband Jack Cooke.Now 88, Margery was recovering from her heart operation, but immediately recognized her brother. John said, “It’s something I never thought that was going to happen but I always hoped it would.” AS well as finding his sister, John has also discovered he now has a nephew, a niece and six grandnieces and grandnephews.1.The headline of the news would be “________”.A.An unforgettable and moving experienceB.The Hannant family lost touch because of warC.A brother and a sister reunited after 60 yearsD.The importance of a letter to WHT2.Margery left her family because ________.A.she attended the air schoolB.she joined the Royal Air ForceC.she had to feed her familyD.a big flood hit her hometown3.Who helped the family reunite after many years?A.Margery’s husband Jack CookeB.The photographer of the photo of Margery.C.A neighbour of Mr Hannant.D.A reader of WHT.BBeing an Olympian (奥运会选手) demands focus, determination, and a competitive spirit. Plus, representing your country is a lot of pressure. However, two athletes recently showed the world another quality that is definitely worth championing.Qatar's Mutaz Essa Barshim and Italy's Gianmarco Tamberi were competing in the high jump on Sunday when they reached a stalemate (僵局). Both men had managed to jump over a surprising 2.37 meters with no faults along the way. However, after three attempts neither managed the next level of 2.39 meters.An Olympic official suggested ajump-offbetween the two friends and rivals (竞争对手) to determine who would get the gold medal. But Barshim had another plan to reward their efforts.“Can we have two golds?” he asked the official.The official agreed and the two men jumped for joy. This was the first time a gold medal had been shared since 1912. “He is one of my best friends, not only on the track, but outside the track. We work together. This is a dream come true.” shared Barshim.The decision to share the medal was particularly meaningful to Tamberi. The Italian had suffered an ankle injury that prevented him from competing in the Rio Olympics in 2016, and it nearly put an end to his career altogether. So this year he brought along his cast to this year's Olympics with “Road to Tokyo 2021” to inspire him along the way.For Barshim, the gold has topped off his already impressive medal collection, having received a bronze and a silver medal in 2012 and 2016 respectively.Despite all the glory of receiving a gold medal for their countries, their achievement means so much more. These two individuals, trying to do their very best for their countries, have provided a wonderful example to all those competing in sports. They've summed up exactly what it means to take part in a global event with a generous and compassionate (有同情心的) spirit.4. What happened to Barshim and Tamberi in the competition?A. They ended in a tie.B. They quit the competition.C. They set a new record.D. They ran out of strength.5. What does the underlined word “jump-off” in Paragraph 3 refer to?A. Debate.B. Vote.C. Celebration.D. Extra round.6. Why was the gold medal particularly meaningful to Tamberi?A. It could bring him a lot of money.B. It may make up for his regret in 2016.C. It was a glory for his country.D. It could complete his medal collection.7. What does the author mainly want to convey in the text?A. The importance of sharing.B. The glory of winning gold medals.C. The valuable and special team spirit.D. The considerate and sharing Olympic spirit.CMy friend and I went traveling inTasmania,Australialast December. We settled in our Airbnb accommodation, a cozy apartment, not long after we arrived inHobart, the capital city.After briefing us on the kitchen's facilities and the whereabouts of the bedroom and bathroom, our hostess Geraldine resumed her ironing work, which seemed to have been interrupted by our arrival.She was ironing what looked like security guard uniforms, and we soon found out that she worked in a local prison. And when she detected the curiosity in our tones, she offered a tour at the prison in her SUV. My friend and I exchanged a “this is incredible” look and said “yes” immediately.As we drove, she told us about the buildings that we were passing, the local market and how to get to MONA,Tasmania's well-known contemporary art gallery.And of course we got to hear some background information about the prison. According to our hostess, it currently holds Martin Bryant, a notorious criminal who cheated 35 people out of their property. We could see the high level of security from the layers upon layers of wires surrounding the gray structure inside.Getting to know a city in such a local way is something I would never be able to do by talking to a hotel receptionist, and this is what I like best about the apartment-sharing experience, not to mention the fact that it's usually cheaper than hotel rooms.But I'm fully aware of the risks of Airbnb, which is why I did my homework before booking online—I checked the reviews of the accommodation to avoid possible safety problems.That said, it is the mutual trust between a host and a guest that fascinates me—the interesting feeling of building a bond with a total stranger.8. Why did the hostess drive us to the prison?A. She planned to send the uniform to the prison.B. She found our curiosity about the prison.C. She wanted to show off her SUV.D. She needed to offer a tour for us.9. Which of the following can best explain the word “notorious” in Paragraph 5?A. Unfamiliar to everyone.B. Particularly disappointing.C. Well known for being bad.D.

It offers a much safer accommodation.D. It provides a chance to know local culture.11. What does the author think of finding accommodation on Airbnb?A. Disapproving.B. Supportive.C. Neutral.D. Doubtful.DIt was very cold and I had been watching a homeless man make himself comfortable in a “shelter” on the river bank. His “shelter” was a tarpaulin (油布)tied to rocks to keep the wind from blowing it away. He had been living there for over a month. I never saw him with warm clothing or food. I knew what I wanted to do.When I told my parents what I wanted to do they werealarmed. They said I could be putting myself at risk, taking a box to a homeless person at night! But I knew, in my deep heart, that I would be safe.I got a box. My parents watched as I added warm gloves, a heavy blanket ... into the box until it was full! Then, I put a Christmas card on top. It said, “Even though we hardly know each other, I want to wish you a Merry Christmas!” I put ten one-dollar bills inside it as well.My father insisted he went there with me as it was 10 pm on Christmas Eve. I said he could drive me but he had to stay in the car. He agreed.I took the box and walked towards his “house”. I called, “Sir, I have a Christmas box for you!”“Go away!” he shouted.“Sir,” I repeated.“Go away!” he shouted.“Why?” I asked him.He walked over and I expected to see an angry face. Instead I saw two of the most beautiful, gentle, blue eyes I have ever seen.“Merry Christmas!” I said.“Why are you doing this?” he asked.“Because you matter to me,” I said. With that I gave him the box.Tears came to his eyes and he thanked me. I got back to the car and watched him carry the box like it was filled with gold. I didn’t want to embarrass (使困窘) him by watching him any more so Dad and I left.12. The underlined word “alarmed” can best be replaced by _____.A. pleasedB. worriedC. disappointedD. surprised13.

When the homeless man saw the author first, he was _____.A. quite angryB. very excitedC. quite puzzledD. very curious15. The author’s purpose in writing the text is to tell readers that _____.A. it is easier said than doneB. poverty is the mother of healthC. where there is a will, there is a wayD. a willing helper doesnot wait until he is asked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。

This is the hottest time of the year in Thailand, so it makes sense that the biggest Songkran tradition is to throw water on people. Thais of all ages join in water fights, using buckets, hoses (软管)and water guns to celebrate the event.Boryeong Mud Festival, South KoreaDon't expect to come home clean after experiencing the Boryeong Mud Festival in South Korea. Famous for its mineral-rich mudflats, visitors rush to Boryeong in July to make themselves in mud, swim in grey pools and enjoy the party. There are even mudslides and a mud skiing competition for those who are seeking the extreme mud adventure!La Tomatina, SpainThe festival dates back to a parade in which some naughty teenagers knocked one performer off his stilts (高跷)and caused a fight of throwing vegetables accidentally. It was once banned until 1957 when the locals held a protest with a funeral. They carried a coffin containing a huge tomato as bands played a funeral march. In the following decades, La Tomatina has become a popular event. If you join the event, be aware that you squash (压扁) the tomato before throwing it. Have a great time but avoid causing any injury.Dia de los Muertos, MexicoBeginning at the midnight of October 31 and lasting through November 2,it is a festival when families gather together to remember those loved ones who have died, aiming to help them on their spiritual journey.

Each woman holds a frying pan with one pancake inside. At the signal, the women flip (轻抛) pancakes and they’re off!This “pancake racing” tradition is said to have started on Shrove Tuesday, 1445, in Olney. Shrove Tuesday is the day beforethe Christian season of Lent (大斋戒) begins. During Lent, many people decide to give up sugary or fatty foods.Legend says that in 1445, an Olney woman was making pancakes to use up some of her sugar and cooking fats before Lent. She lost track of time and suddenly heard the church bells ring, signaling the beginning of the Shrove Tuesday service. Realizing that she was going to be late for church, she raced out the door still wearing her apron and headscarf and holding her frying pan with a pancake in it. In the following years, the woman’s neighbors imitated her dash to church, and pancake racing was born.The rules are simple. Racers must wear the traditional headscarf and apron. They must flip their pancakes twice - once before starting and once after crossing the finish line. After the race, there are Shrove Tuesday church services. Then Liberal and Olney connect through a video call to compare race times and declare a winner.In both towns, the races have grown into larger festivals. Olney’s festival is an all-day event starting with a big pancake breakfast. Liberal’s festival lasts four days and includes a parade, a talent show, and contests that feature eating and flipping pancakes. Although the women’s race is still the main event, both towns now hold additional races for boys and girls of all ages.4. How did pancake racing start?A. A woman in Olney created it.B.

When he was six, his teacher, Madame Sambin, told him stories about her husband, who disappeared while traveling the world on a ship 30 years before. She told her class that he was like Robinson Crusoe, a fictional castaway who lived on a desert island. Verne would later write stories about similar characters.In 1847, Verne was sent by his family to study law at a university in Paris, but he preferred to write novels, poems and plays. After graduating, he realized he wanted to write adventure stories based on science and technology.Thishad never been done before, but Verne was sure that it would be a success. His first story, Five Weeks in a Balloon, was published in September 1862. His career lasted for more than 40 years, during which time he wrote more than 60 gripping stories.To begin with, Verne wrote positive and optimistic books. Many of these were to be his most popular creations. Although some included fantastical elements, they were usually based in scientific fact, making them believable. These happy stories weren’t to last. As he got older, Verne became less confident in the idea that science and technology were always good for the planet. His books started to include more scientists who used technology for their own-sometimes evil - purposes. Verne died on 24 March 1905, but new books continued to be published until 1919. These stories were based on ideas Verne had written about while he was still alive, but featured new characters and plots created by his son, Michel.In the 20th century, his books were translated into more than 140 languages and several successful film versions were released. His creations have been recognized as an inspiration for many scientists and inventors. Many of the futuristic ideas from his most popular books have since come true.8. What is the purpose of Paragraph 1?A To show Verne’s discovery.B. To offer the background information of Verne.C. To tell of the adventure of Sambin’s husband.D. To explain how Verne began his writing career.9. What does the underlined word “This” refer to in Paragraph 2:A. Writing novels, poems and plays.B. Studying law.C. Graduating from university.D. Wring adventure stories.10. What can be learned about Verne’s late works?A. They covered happy elements.B. They were unbelievable stories.C. They revealed Verne’s doubt on science.D. They were partly written by Berne’s son.11. Which of the following best describes Verne?A. Talented and productive.B. Popular and caring.C. Optimistic and generous.D. Friendly and honest.DNextdoor，an online social network for neighbors，says it has attracted $60 million from early backers of technology giants，Google，Amazon and Facebook.The new investment，1ed by venture firm Kleiner Perkins Caufield & Byers and investment firm Tiger Global Management，values Nextdoor at more than $500 million，said a personfamiliar with the matter.Nextdoor members make Facebook-style postings，giving or seeking recommendations for services such as babysitters and yard maintenance or local retailers and restaurants. They also post about community issues suchas parking，crimeand safety，or items for sale or loan.The investment sum emphasizes the appeal of businesses that can tap into the growing use of mobile devices，as well as social networking Perhaps the best current example is Twitter，which is preparing for an initial public offering that values the company at up to about $11 billion.“We’re all spending more time with our screens，more engaged，but I think data shows we’re less connected，”said John Doerr of Kleiner Perkins，mentioning his own experience of knowing few of his neighbors. Nextdoor，with its ability to introduce neighbors to each other，helps people regain the sense of connection，he said.Early next year，Nextdoor plans to expand to Canada，followed by Great Britain，Australia，and South Africa，chief executive NiravTolia said. While Nextdoor has not yet have made any profit after two years of operations，Tolia said he is not worried.“If we look at the great companies at this stage，none of them started to monetize this early in their evolution. ”Tolia said. “It’s all about getting the product right. ”Eventually，Nextdoor plans to tap into local advertising，he said.Nextdoor is currently used in 22，527 neighborhoods across the United States，up from 5，694 a year ago.

Not quite, if we consider the state of second language learning in schools across the country. According to a 2018 study, Europe often tops the U.S. in foreign language education in school. 92% of Europeanstudents are learning a foreign language in school. In America it’s only 20%. In more than 20 European countries, studying a foreign language for at least one year is compulsory. In comparison, only 10 states and D.C. require learning a foreign language for graduation.I went to a public school in Pennsylvania that ranked onNewsweek’s list of America’s top high schools in 2015. Foreign language learning was not a graduation requirement. A common response to such stories and statistics is: So what? Why should Americans care about learning another language when English has recently seemed to dominate as the official language of the world?The world is globalizing faster than we can imagine. More than half of the world’s population speaks more than one language. It is also increasingly becoming the need for success in this globalizing world. Having the ability to speak a second language opens up the possibility of travelling and immersing yourself in another part of the world. This means people can feel other cultures, and traditions in places you were previously kept away because you could not communicate in the language.The teaching of foreign languages can be instrumental in bringing about peace and unity in the country we live in. Learning a second language can be an efficient vehicle to help to bridge communities. To speak another language means having access to a universe of different experiences and world views of another community of people.4. Why does the writer mention Europe?A. America makes studying a foreign language compulsory.B. America is the glorious symbol of multiculturalism.C. America isn’t really qualified as the developed world.D. America doesn’t focus on foreign language education5. What is American’s attitude towards education of foreign languages?A. Less concerned.B. More worried.C. Quite doubtful.D. Very supportive.6. What can visiting people do if they can speak the language where they visit?A. Make the world globalizing.B. Achieve success in business.C. Experience people’s real life there.D. Keep away their own culture.7. What is the main idea of the last paragraph?A. Using a second language can bring harmony.B. Communities of people enjoy the great views.C. Speaking another language is reallynecessary.D. Learning a second language can be difficult.CIt's a popular belief that a fish's memory lasts for only seven seconds. It may seem sad to think that they don't remember what they've eaten or where they’ve been, and they don't identify you or any of their friends--every moment intheir life would be like seeing the world for the first time.But don't be so quick to feel sorry for them. A new study has found that fish have a much better memory than we used to think. In fact, certain species of fish can even remember events from as long as 12 days ago. In the study, researchers from Mac Ewan University in Canada trained a kind of fish called African cichlids to go to a certain area of their tank to get food.They then waited for 12 days before putting them back in the tank again. Researchers used computer software to monitor the fish’s movements.They found that after such a long break the fish still went to the same place where they first got food. This suggested that they could remember their past experiences.In fact. scientists had been thinking for a long time that African cichlids might have a good memory. An earlier study showed that they behaved aggressively(挑衅地) in front of certain fish, perhaps because they remembered their past "fights".But until the latest findings, there was no clear evidence.Just as a good memory can make our lives easier, it also plays an important part when a fish is trying to survivein the wild. "If fish are able to remember that a certain area contains safe food, they will be able to go back to that area without putting their lives at risk,"lead researcher Trevor Hamilton told Live Science.For a long time, fish were placed far below chimpanzees, dolphins and mice on the list of smart animals.But this study has given scientists a new understanding of their intelligence.8. According to the text, people commonly believe that ______.A. fish don't recognize any of their friendsB. a fish's memory lasts for only seven minutesC. fish can only remember part of their past experiencesD. fish can remember things that happened long ago9. How can fish benefit most from a good memory?A. They can remember their enemies and fight.B. They can remember where to get food and survive.C. They can remember their friends and help each other.D. They can remember where to go when in danger.10. What can we learn from the text?A. Only African cichlids have a good memory.B. African cichlids can remember things for 12 days.C. African cichlids always treat other fish aggressively.D. African cichlids don't belong to the list of smart animals.11. What is the text mainly about?A. What we can learn from fish.B. Fish having a very bad memory.C. How fish improve their memory.D. Fish being smarter than we thought.DIf you have ever been disappointed because you don’t have a good gardener ,the clever robot may one day become the helper of your indoor plantsThe Hexa Plant is a six-legged robot that has been specially made to care for the potted plant that carries on top of its head .Using light and heats sensors (传感器) the robot has the ability to carry its plant in and out the daylight .If the houseplant needs more sun，the Hexa will walk into the sunlight ;and if the houseplant is getting too hot , the Hexa will go back into the area that blocks direct light The Hexa Plant will even do a little dance when it senses that the plant needs to be watered to warn its owner .The robot was developed by Vincross engineer and founder Sun Tianqi after he saw a dead sunflower sitting in the darkness in a room back in 2014 .” Plants only receive an action without responding ,”SunTianqi wrote in a blog post .” Whether they are being cut ,bitten ,burned or pulled from the earth ,or when they haven’t received enough sunshine ,water ,or are too hot or cold ,they will hold still and take whatever is happening to them .According to Sun Tianqi ,for billions of years ,plants have never experienced movement of any kind ,not even the simplest movement .In their whole lives ,they stick to where they were born .Sun Tianqi continued ,” Do they want break their own settings or have a tendency towards this ?I do not know the answer ,but would love to try to share some of this human tendency and technology with plants With the help of the robot ,plants can experience the move”.The Hexa Plant model robots are not for sale ,though Vincross does sell a Hexa robot model .It is said that in the near future the robots can open up a new market to watch over our household plants12.

These schools are primarily located in the Northeastern part of the country. There are eight total colleges that are considered to be Ivy League. These schools are Brown, Harvard, Cornell, Princeton, Dartmouth, Yale, and Columbia universities and the University of Pennsylvania. Of all institutions of higher learning, these elite schools are considered to be the most outstanding and the most sought-after in terms of acceptance and graduation.The term “Ivy League” came about in 1954 when the NCAA athletic conference for Division I was formed. At the time, the elitism of these schools was really due to their prestige in the realm of sports like basketball. Although the term “Ivy League” was not created until the 1950s, many of these schools were in existence as far back as 1636, when John Harvard became the first benefactor of Harvard University.Although this group of elite schools is considered to be part of one big league of the elite, there have been plenty of internal rivalries over the years. The sports that these colleges play were so popular that some teams began playing games in New York City so spectators could come from far away and watch the games. The popularity of both the athletes who played and the college team rivalries brought in a good deal of attention to the schools as well as revenue from ticket sales. There have also been academic rivalries between schools. Mostly, these rivalries are a matter of opinion in terms of which school has the most honor graduates, which schools offer the most prestigious scholarships, and what famous graduates have come from each school.Each Ivy League college has its own unique accomplishments that make it important. All carry a certain reputation with them, and each school has programs that excel primarily in the medical and law fields, making them some of the most sought-after schools in the world. Their admission process is very selective, which helps the schools ensure that they only accept the best and brightest. Many famous people have graduated from IvyLeague schools, including recent presidents George W. Bush, Bill Clinton, and Barack Obama. This prestige leads many to believe that these colleges are only for the wealthy and elite. Often, companies look for Ivy League graduates as potential employees, usually preferred by law firms, medical facilities, and large corporations. It has long beencovetedto have earned a degree from an Ivy League school. Today, the Ivy League schools are still excellent in both academia and in sports, and they have left a legacy of higher education with an exceptional track record and reputation to go along with them.4. Which of the following statements is true according to the passage?A. Ivy League schools were initially famous for their reputation in sports.B. Ivy League schools didn’t come into existence until the 1950s.C. Ivy League schools do not compete with each other within the league.D. Ivy League schools are most popular for their excellence in the medical and law fields.5. Which of the following aspects is NOT mentioned in the passage?A. The history of the Ivy LeagueB. The rivalry of the Ivy LeagueC. The accomplishments and cultural impacts of the Ivy LeagueD. The future development of the Ivy League6. Why do many people believe that Ivy League colleges are only for the wealthy and elite?A. Because they are the most sought-after schools in the world.B. Because they have selective admission process to help ensure the quality of their students.C. Because many famous people have graduated from Ivy League schools.D. Because manycompanies look for Ivy League graduates as potential employees.7. What does the underlined word “coveted” in the last paragraph probably mean?A. advocatedB.DesiredC. restrictedD. sponsoredCJIANLI, Hubei Province, June 2 (Xinhua) — A cruise ship carrying more than 450 people sank in the Yangtze River overnight, which could be China’s worst sinking disaster in decades.

I was so excited to start a new part of my life.Soon enough, the big day came, but it wasn't like what I had thought. The first two weeks were the most difficult days of my entire life. Every night I would cry myself to sleep. I was missing my family, my home and everything in my hometown so much and I didn’t know how to deal with my broken heart.To distract myself, I threw myself into my studies. I also found a ton of jobs. In any free time, I started forcing myself to go to the gym. I wanted to keep every part of my day busy so I wouldn’t think about how lonely I felt. Soon after, I began to control my eating, considering it another solution to my homesickness. But soon there was something wrong with me.Finally, I went to see a doctor. When the doctor told me I had no choice but to take time away from school, I started to fear. How could I stop? School was what I was best at. “I’m not so bad,” I thought in my head. But the result was that I was taken to hospital again a month later and my mother camewoefully. I had to take a semester off from school, and go to the treatment center near my home.If there are girls who are suffering similarly, I hope you know that there is hope and that you should have a positive attitude towards life.

2021年广州市第四十七中高三英语月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ALast summer, Katie Steller pulled off the freeway on her way to work inMinneapolis. She stopped at a traffic light, where a man was sitting with a sign asking for help. She rolled down her window and shouted. “Hey. I’m driving around giving free haircuts. Do you want one right now?” The man laughed, then paused. “Actually,” he said, “I was really hoping to get a haircut.” Steller pulled out a red chair from her car and helped the man cut his hair immediately. After the work was done, the man looked in a mirror. “I look good!” he said.Up to now, Steller has given 30 or so such haircuts around the city to people with little influence, and she is strongly aware of the power of her cleanup job.As a teen, she suffered from a severe disease, causing her hair to get thinned, so her mother arranged for Steller’s first professional haircut. “To sit down and have somebody look at me and talk to me like a person and not just an illness, it helped me feel cared about and less alone,” she says. After that, Steller knew she wanted to have her own barbershop so she could help people feel the way she’d felt that day. Not long after finishing cosmetology (美容术) school in 2009, she began what she now calls her Red Chair Project, reaching out to people on the streets. Her aim was that by doing some kind acts, others would be inspired to spread their own.“Part of what broke my heart was just how lonely peoplelooked,” she said. “I thought maybe I’d go around and ask if people want free haircuts. I can’t fix their problems, but maybe I can help them feel less alone for a moment.”It all began with a belief in simple acts of kindness, such as a free haircut. “The way you show up in the world matters,” said Steller. “You have no idea what people are going to do with the kindness that you give them.”1. How does the writer begin the passage?A. By making a comparison.B. By giving a reason.C. By raising a question.D. By describing a scene.2. What made Stellar start the Red Chair Project?A. Her mother’s love for her.B. Her interest in cosmetology.C. Her care for those in need.D. Her wish to fight severe diseases.3. What did Stellar expect from the project?A. To spread kindness.B. To solve social problems.C. To deal with relationships.D. To make people look smarter.BA city inSouth Korea, which has the world’s largest number of people using smartphones, has placed flashing lights and laser beams at a road crossing to warn “smartphone zombies” to look up and drivers to slow down, in the hope of preventing accidents.The designers of the system were motivated by growing worry that more pedestrians glued to their phones will become victims in a country that already has some of the highest road death and injury rates among developed countries. State-run Korea Institute of Civil Engineering and Building Technology (KICT) believes its system of flashing lights at zebra crossings can warn both pedestrians and drivers.In addition to red, yellow and blue LED lights on the pavement, “smombies” - smartphone zombies - will be warned by laser beam projected from power poles and a warning sent to the phones by an app that they are about to step into traffic.“Increasing number of smombie accidents have occurred in pedestrian crossings, so these zombie lights are essential to prevent these pedestrian accidents,” said KICT senior researcher Kim Jong-hoon. Drivers are warned by the flashing lights, which have shown to be effective 83.4 percent of the time in the institute’s tests involving about 1,000 vehicles.In 2017, more than 1,600 pedestrians were killed in auto related accidents, which is about 40 percent of total traffic deaths, according to data from the Traffic Accident Analysis System. For now, the smombie warning system is placed only in Ilsan, a suburban city about30 kmnorthwest of the capital,Seoul, but is expected to go nationwide, according to the institute.Kim Dan-hee, a 23-year-old resident of Ilsan, welcomed the system, saying she was often too absorbed in her phone to remember to look at traffic. “This flashing light makes me feel safe as it makes me look around again, and I hope that we can have more of these in town,” she said.4. What do the underlined words “smartphone zombies” in paragraph 1 refer to?A. Drivers driving after drunk.B. Pedestrians buried in their phones.C. Passengers crazy about phones.D. Policemen in charge of traffic.5. What do we know about the warning system?A. It has reduced death rate by 83.4%.B. It has been spread nationwide.C. It gives a warning to the smartphones.D. It is being tried out in many places.6. What was the residents’ attitude to the traffic system?A. Negative.B. Unconcerned.C. Disapproving.D. Favorable.7. What is the best title for the text?A.South KoreaWarns Smartphone Zombies of TrafficB. Flashing Lights Are Used to Prevent AccidentsC. Smartphone Zombies Are Causing Traffic AccidentsD.South KoreaUses a New Traffic SystemCChina's Mars probe Tianwen-1 successfully landed on the surface of the red planet on May 15, 2021, leaving a Chinese footprint on Mars for the first time and in its first attempt, becoming the only other nation besides theUSto get such an achievement.

According to the administration, the country's first Martian probe will conduct scientific investigations about the Martian soil, environment, atmosphere as well as water.China's planetary exploration program has been named “Tianwen”, which was named after a long poem by the famous ancient poet Qu Yuan. The name represents the Chinese nation's willpower in pursuing truth, the country's cultural inheritance of its understanding of nature and universe, as well as the unending exploration in science and technology.China's first Mars rover has been named “Zhurong”, which means the god of fire in an ancient Chinese story. The name indicates Chinese people's blessing for the rover to light the flame ofChina's planetary exploration. The rover has six wheels and four solar panels, and carries 13 scientific instruments. According to the CNSA, Zhurong has started its scientific exploration after moving from the landing platform onto the Red Planet's surface on May 22.More than 40 Mars missions have been launched since the 1960s, but only about half have succeeded. It is the first time in the world that orbiting, landing and roving on Mars has been completed in one launch mission,andChinahas come to the forefront of Mars exploration in the world.8.

But few of them have gone as deeply and frighteningly into the corners of adeterioratingmind as The Father,a powerful new drama built around a spellbinding performance from Anthony Hopkins.At this point in his long career,Hopkinswould seem to have exhausted his ability to surprise us, but his work here is nothing short of astonishing. His character, also named Anthony, is 80 years old and has dementia. At the beginning of the movie, his daughter, Anne — played by Olivia Colman — stops by hisLondonapartment to check on him. Her father's condition has taken a turn for the worse, and his temper has become severe enough to send his latest live in nurse packing. Anthony is stubborn and defiant and insists that he can manage on his own. But that's clearly not the case, given his habit of misplacing his things and his inability to remember names and faces, Anne's included.As The Father goes on, the more it becomes clear that it's his own mind that's playing tricks on him. What makes the movie so unsettling is the way it wires us directly into his subjective experience, so that the foundations of the story seem to shift at random from scene to scene. A man suddenly appears in the apartment, claiming to be Anne's husband, which is odd, since just a few moments earlier, Anne seemed to be single. Anne goes out shopping for groceries, but when she returns, she's played not by Olivia Colman but by another actress, Olivia Williams. Even the apartment itself begins to shift. You notice puzzling differences-wasn't there a lamp on that hallway table just a moment ago?The story in The Father may be complicated but it's also heartbreakingly simple: man grows old and loses his memory, and his daughter, after lifetime of love and devotion, must begin the long painful process of saying goodbye.Hopkinsshows us Anthony's struggle to keep his sense about him. It's a striking performance-and an impossible one to forget.12. What does the underlined word “deteriorating” mean in the first paragraph?A. Worsening.B. Narrowing.C. Recovering.D. Improving.13. What do we learn about the character Anthony in the movie?A. He can take care of himselfB. He drives away the nurses.C. He is easy-going and forgetful.D. He lives with his daughter all the time.14. The shift of scenes in the movie is designed to .A. build the dramatic tension in the family.B. show off the well-designed story line.C. frighten the movie-goers with mysterious plot.D. involve the viewers into thedisordered memories.15. What does the author think ofHopkins?A. He has run out of his talent.B. He is not suitable for the roleC. He masterly plays the old man.D. He presents an odd performance.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。

Luckily, the address is inside, so she returns it to the piano teacher who left it there. She then discovers that the piano teacher makes a habit of dropping bags around the city on purpose to make new friends. Directed by Neil Jordan, the actors are attractive. Grace Moretz is the waitress and Isabelle Huppert is the one who admires her. Thanks to them, Greta winds up being far more enjoyable than it has any right to be.The AftermathThe Aftermath is one of the few World WarⅡ-related films. Based on Rhidian Brook’s novel,this touching romantic movie is starred by Keira Knightley, who is the wife of a British officer. She hates the Germans because her son was killed in an air raid. But is there a chance that a tall, dark andhandsome man might persuade her to overcome her hate?Captain MarvelIt took Marvel Studios a decade to finally make a female superhero.

National GeographicBThereare two days that set you on your path in life: the day you’re born, and the day you realize why you were born.Growing up south of Chicago in Harvey, Illinois, most people just had their heads down trying to make it from point A to point B. I was the same way, just going with the flow. I played basketball in high school because I was good at it and because other people thought I should until I discovered my talent.I give up basketball and started doing speeches. It wasn’t a popular decision but my grandfather told me to do what made me happy. I fell in love with comedy and performing. And when I discovered the passion, I realized why I was born.I knew I had something to offer —I knew that not only am I powerful, but I can make a difference.I realized a long time ago that my dream is not to be famous or rich. My talent is to entertain. But it’s more than that. I have the chance to reach people, to brighten days, to bring laughter and positive energy into lives and inspire. And I am grateful forit.Acting putting myself out there and having doors closed on me time and time again has taught me a lot about myself. I have learned to trust what I have to offer the world over momentary doubt. I’ve learned to put my faith over my feelings. And I've grown a tough skin. More importantly, I have learned there is a long way towards our goals and that when we put our talents and passion to work, we determine our value.Like a lot of places across the country, there’s poverty, crime, violence and unemployment in Harvey.

He was then awarded 157 credit points after the image was uploaded and recognized by artificial intelligence. The credit points can be used to buy gifts, such as books, cellphones and red wine, or to purchase charity meals donated to children in poor rural areas.The "Clear Plate" mini-program has become popular among young Chinese. Similar campaigns like an "empty plate challenge" are alsoon the horizonin many Chinese universities."Technological innovation is a good way to reduce food waste," said Liu Jichen. Founder of the start-up that developed the app. The idea popped up at a dinner in 2017, when Liu found that the restaurant owner would give diners who polished off their food a card and offer small gifts after a certain number of cards had been collected. "Everyone who values food is bound to enjoy a sense of gain at a lower cost," Liu mentioned this case, noting that such an idea could potentially be realized online.He formeda team to work on the project. Yet it was quite a challenge for the AI system to assess whether the uploaded photos showed empty plates. To make the AI system smarter，Liu and his team, assisted by more than 1, 000 others, spent half a year collecting over100,000 samples from canteens and restaurants across the country and analyzed the data. Dozens of enterprises, institutions and restaurants have contacted the start-up to cooperate on the project.

AI programs encouraging diners toclear their plates.D. AI programs collecting pictures of clearing diners' plates.DTo show empathy is to identify with another’s feelings. It is to emotionally put yourself in the place of another. The ability to empathize is directly dependent on your ability to feel your own feelings and identify them.If you have never felt a certain feeling, it will be hard for you to understand how another person is feeling. If you have never put your hand in a flame, you will not know the pain of fire. If you have not experienced jealousy, you will not understand its power.Readingabout a feeling and intellectually knowing about it is very different than actually experiencing it for yourself.Among those with an equal level of emotional intelligence, the person who has actually experienced the widest range and variety of feelings — the great depths of depression and the heights of fulfillment, for example, — is the one who is most able to empathize. On the other hand, when we say that someone “can’t relate” to other people, it is likely because they haven’t experienced, acknowledged or accepted many feelings of their own.Once you have felt discriminated against, for example, it is much easier to relate with someone else who has been discriminated against. Our innate emotional intelligence gives us the ability to quickly recall those instances and form associations when we encounter discrimination again. We then can use the “reliving” of those emotions to guide our thinking and actions. This is one of the ways nature slowly evolves towards a higher level of survival.For this process to work, the first step is that we must be able to experience our own emotions. This means we must be open to them and not distract ourselves from them or try to numb ourselves from our feelings through drugs, alcohol, etc.Next, we need to become aware of what we are actually feeling — to acknowledge, identify, and accept our feelings. Only then can we empathize with others. That is one reason why it is important to work on your ownemotional awareness and sensitivity — in other words, to be “in touch with” your feelings.12. How does the author explain the feelings of empathy?A. By giving examples.B. By having classification.C. By making comparison.D. By providing data.13. Which statement may the author agree with?A. Low level of empathy leads to fewer varieties of feelings.B. The deeper one’s feelings are, the more empathetic one is.C. Empathy is a way we recently picked up for better survival.D. Rich experiences may not go with a high level of empathy.14. What’s the purpose of the last two paragraphs of the text?A. To advise a sincere attitude to one’s experiences.B To suggest a right understanding of empathy.C. To require a realbond with one’s emotions.D. To call for true acceptance of one’s feelings.15. What is the best title for the text?A. How Empathy UnfoldsB. Be Open to Your EmotionsC. Why Is Empathy ImportantD. Accept Your True Self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。

Here is a list of four noteworthy art fairs.Art Basel, Basel, SwitzerlandThe granddaddy of art fairs, Art Basel, was established in 1970 by a group of local art gallerists and is the biggest contemporary art fair in the world. Art Basel takes place over a 5-day period each June in Basel, Switzerland. The high cost of renting space for gallery owners is offset（抵消）by the huge attendance at the fair. For example in 2010, about 60,000 visitors attended Art Basel.Frieze Art Fair, London“Frieze Art Fair was established in 2003 and is one of the few fairs to focus only on contemporary art and living artists.v"Thefair takes place every October in Regent's Park, London. It features over 170 of the most exciting contemporary art galleries in the world. ”In addition to the fair which began in 2003, the fair owners Matthew Slotover and Amanda Sharp publish Frieze, an international art magazine established in 1991 and devoted to contemporary art.TEFAF Maastricht, the NetherlandsEstablished in 1975 as The Pictura Fine Art Fair, and renamed The European Fine Art Foundation（TEFAF）, Maastricht in 1996, the fair includes 260 of the world's most famous art and antique dealers from 16 countries.The 24th edition of the TEFAF fair held March 18 — 27, 2011 featured 260 dealers exhibiting approximately 30, 000 artworks and antiques with an overall value of $ US 1. 4 billion.ARCO, MadridARCO Madrid was established in 1982 and is one of Europe's leading and popular art fairs.

Rising from the center of the Arctic Basin, the flag sent a clear message to the surrounding nations: Russia had just laid claim(权利) to the vast oil and gas reserves contained in this underwater area.AfterRussia, theUnited States,Norway,SwedenandFinlandare all trying to gain profit. Projections show that the area of land and sea that falls within theArctic Circleis home to an estimated 90 billion barrels of oil, an incredible 13% of Earth’s reserves. It’s also estimated to contain almost a quarter of untapped global gas resources. But long before this oil race began, how did theArcticbecome so rich in energy?“The first thing you realize is that theArctic—unlike the Antarctic—is an ocean surrounded by continents”, Alastair Fraser, a geoscientist from Imperial College London, said. Firstly, this means there’s a huge quantity of organic material available, in the form of dead sea creatures such as plankton and algae, which form the basis of what will ultimately become oil and gas. Secondly, the surrounding ring of continents means that the Arctic Basin contains a high proportion of continental crust(大陆地壳), which makes up about 50% of its oceanic area. That’s significant because continental crust typically contains deep depressions called basins, into which organic matter sinks.Here, it gets inserted in rock and preserved in anoxic(缺氧) waters, meaning they contain little oxygen. “Normally, in a shallow sea with lots of oxygen, it would not be preserved. But if the sea is deep enough, the oxygenated waters at the top will be separated from the anoxic conditions at the base,” Fraser explained. Conserved within these oxygen-free basins, the matter maintains compounds that finally make it useful as an energy source for millions of years in the future.4. Why didRussiaplant a national flag onto the Lomonosov Ridge?A. To tell surrounding countries its armed forces.B. To show its advanced technology of submarines.C. To show abundant natural resources in theArcticBasin.D. To claim its privilege to explore for oil and gas in the area.5. What’s the function of the last sentence in paragraph 2?A. Making a comparison.B. Serving as a connecting link.C. Analyzing the cause and effect.D. Drawing the conclusion of the text.6. What can we know from the last paragraph?A. Oxygen only exists in the top part of the ocean.B. Organic materials mostly exist in the basins with oxygen.C. Water containing oxygen turns organic materials into oil and gas.D. Oxygen-free environment counts in the formation of the arctic’s rich energy.7. What can be a suitable title for the text?A. What makes theArcticattractive?B. Why do many nations focus on theArctic?C. Why is there so much oil in theArctic?D. How does theArcticBasincome into being?CAfter almost an entire year of not going shopping and vacationing, you find the numbers reflected by your bank 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 forthe living, so live it sensibly.8. 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.9. What does the underlined phrase “refrain from” mean in Paragraph 3?A. select fromB. hold backC. rely onD. prefer to10. 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.11. 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.DPeople from Britain and Ireland first came to live in Australia in 1788. They brought different dialects (方言) of English with them. These different kinds of English began to mix and change. The newcomers soon began to speak with their own typical accent (口音) and vocabulary. More and more people came to Australia during the Gold Rush in the 19th and 20th centuries. Some came from Britain and Ireland; others came from non-English speaking countries. Australian English continued to grow and change.Australian English has also been influenced by American English. During the Second World War, there were many American soldiers staying in Australia. More importantly, American television shows and music have been popular in Australia since the 1950s.Australians use many words that other English speakers do not use. The famous Australian greeting, for example, is G’day! A native forest is called the bush and central Australia is called the outback. Many words werebrought to Australia from Britain and Ireland. For example, mate means “friend”, and it is still used in Britain. Some of these words have changed in meaning. Some words have come from Australian original languages, many of which are names for animals, plants and places, like dingo and kangaroo.Australian spelling comes from British spelling. In words like organise and realise, -ise is the expected and taught spelling method. In words like colour, favourite, -ouris the normal, but nouns such as the Labor Party and Victor Harbor are spelled with -or. Program, on the other hand, is more common than programme.There are also differences in the definition (定义) of words Australians use in different parts of the country. For example, football means “rugby” in New South Wales and Queensland, but “Australian rules football" in everywhere else in Australia. In New South Wales, a swimming costume is called a cossie or swimmers, while in Queensland it is called togs and bathers in Victoria.12. What does paragraph 1 mainly talk about?A. Reasons why English is important.B. Different dialects of Australian English.C. Various aspects that Australian English has been influenced.D. Changes of the accent and vocabulary in English.13.

2021届广州市第四十七中高三英语月考试卷及答案
2021届广州市第四十七中高三英语月考试卷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AIt's just before l pm and hungry guests are starting to emerge out onto the wooden floor at the back of the Victoria Falls Safari Lodge in Zimbabwe. A few have already settled in for lunch, drinking beer and enjoying their sandwiches and salads in the sunshine. It's a normal setting until you look up. Overhead, the sky is filled with several hundred vultures (秃鹭).They too have arrived for their midday snack. Every day the team at this hotel places last night's leftover meat out for the vultures to eat. They call it the "Vulture Restaurant" and it's a vital part of protecting these birds, who have become some of the most endangered species in Africa.In Zimbabwe, where illegal hunting of elephants and rhinos is a major issue, poisoning poses a significant threat to the birds. "In recent years hunters have realized they can use poison to kill animals. It's effective because it's silent and therefore doesn't attract much attention.when the vultures eat the bodies of the dead animals they die too," says Roger Parry, Wildlife Manager at the Victoria Falls Wildlife Trust.The Vulture Restaurant initiative is part feeding programme, part education programme. By attracting the birds to the Vulture Restaurant every day the team can ensure they're regularly getting a safe meal, and while the birds are there they can educate tourists from all over the world about these creatures.“Lunch” is served by Moses Garira. He has the unenviable task of wandering out into the middle of the clearing with a box full of meat, dropping the contents onto the ground and running for his life as the vultures fly downward suddenly for their food. No one, surely, would volunteer for this role, but Garira rather enjoys it. Back in the safety of the viewing seats, he tells the onlookers about the importance of vultures. "They're hugely important in terms of their role of cleaning up the bodies of dead animals," says Garira. "Notably, they're safely able to digest bacteria like anthrax. Without vultures, there'd be a lot more disease in the world."1. What's the biggest threat vultures facing in Zimbabwe?A. Overhunting.B. Unsafe food.C. Loss of habitat.D. A bird disease.2. What would others think of Garira's job?A. Scary.B. Relaxing.C. Well-paid.D. Time-consuming3. What do Garira's words mean?A. Birds are human's best friends.B. People know little about vultures.C. Vultures are environmentally favorable.D. Vultures are in urgentneed of protection.BNina Wygant, 11, sits in front of a long table in a classroom that looks more like a trendy coffee shop than an elementary school classroom. Some of her fifth-grade classmates at Hopewell Memorial Junior High School sit on high-top chairs at counters. Others choose to sit in club chairs or soft bean bags in comfortable. "I like it because it gives us an environment we like or need to settle down and read a book that we would like to concentrate on instead of having desks and being all quiet," said Vivian Garcia, 10. “You can just space out and have your own little area. I find it very amazing that you can pick your own books instead of being told what to read.”That’s the end goal, said teacher Heather Shadish. Reading has always been a passion for this English language arts and science teacher, a passion she instills（灌输）in her pupils. Back then, in her literature class in graduate school at Chatham University, a professor read aloud the first chapter ofBecause of Winn-Dixieby Kate DiCamillo, a Newbery Medalist. "That was the moment I knew I wanted to some day teach reading. There was a spark there. I just felt these are the kind of books I need to share with kids ---the books that are going to make them feel something and make them fall in love with reading instead of reading being achore.”But information in children's workbooks is limited, so they open tablets and connect to Epic - a digital library that's free to educators and librarians, but $7.99 a month for parents — giving kids unlimited access to approximately 35,000 books（both print and audio）, quizzes and videos to enhance learning.“Epic gives students access to information not found in a textbook and presents it in a more interesting way," she said.4.

Study author Brent Coker said, “Surfing the Internet at times helps increase an employee's attention.”“People need to relax for a bit to get back their attention,” Coker said on the university's website. “Having ashort break, such as a quick surfing of the Internet, helps the mind to rest itself, leading to a higher total Internet attention for a day's work, and as a result, increases productivity (生产效率),” he said.According to the study of 300 workers, 70 percent of people who use the Internet at work surf the Internet for their own reasons during office hours. Among the most popular surfing activities are searching for information about products, reading online news, playing online games and watching videos. “Firms spend a lot of money on software toblocktheir employees from watching videos, using social networking sites or shopping online,” said Coker. “That's not always a good idea.”However, Coker said the study looked at people who surfed the Internet in moderation (适度), or were on the Internet for less than 20 percent of their total time in the office. “Those who spend too much time surfing the Internet will have a lower productivity than those without.” he said.12.

It is well worth noting that Thai culture hasbeen handed down from one generation to the next.Thai Classical DanceThe inspiring culture includes local music and wonderful Thai dances. The dances of course have something to do with its deep-rooted Buddhist religion, fighting arts and beautiful clothing. Thai classical dance performances are generally performed by gracious (高雅的) Thai ladies wearing beautiful Thai local costumes. Most resort (旅游胜地) areas and many hotels frequently offer these Thai culture dance shows for foreign visitors.Thai GreetingThe unique Thai gesture of greeting another person, the wai, is especiallyone of the great aspects of Thai culture. The wai is when a person joins both hands to either head or chest level while bending their head slightly towards his hands. This way of greeting is especially done when a younger person greets an older person and it indicates a sign of respect to their elders. Employees would also wai their managers even if the manager would be younger than themselves.BangkokBangkok is the culture center of Thailand and has been the Thai capital since the end of the eighteenth century.

Bangkok offers a package of Thai culture which is shown by numerous beautiful Buddhist temples and many examples of modern Thai architecture.Bangkok National MuseumAnother location in Bangkok where one can enjoy and see Thai culture is at the famed Bangkok national museum, which offers tourists an opportunity to view national treasures and unique Thai art pieces with its culture feature dating back as early as the late sixteenth century.1.Thai classical dance is related to ________.A.its living level and educationB.its history and architectural styleC.its customsD.its religious belief2.In Thailand a worker uses the gesture, the wai , to greet________.A.his close friend.B.a young stranger.C.his younger colleagues.D.his young boss.3.What make Thai culture in Bangkok so unique?A.The long history and fine weather of Bangkok.B.The mixture of the modern culture and traditions.C.A number of beautiful Thai Buddhist templesD.Many examples of modern Thai architecture.BThere are many useful things we can do each day to feel better. It may take some efforts and time to make a habit of drinking 8 glasses of water daily or thinking more positively, but it is well worth it. What things do you do every day to feel better?Probably the healthiest thing you can do to feel better each day is to exercise early in the morning. You don't have to run the whole morning or spend a few hours in the gym. Even doing some easy exercise like walking, sit-ups or jumping the rope will help you feel better in no time!Again, due to our busy schedules, we don't get enough sleep each night. If you have trouble falling asleep, avoid watching TV or surfing the Internet right before bed. Also, try to make healthy bedtime snack choices and don't drink tea or coffee too late in the day.If you drink 3 glasses of water, 4 glasses of coffee or tea and a glass of soda each day and think that you drink enough water, think again. Your body needs water (not coffee or soda!) to function properly. Aiming to drink 7-8 glasses of water each day can make you feel better.Being positive is the key to a longer life. Positive thoughts can help improve your overall heath.

She was divorced and had three kids under age 7 when she was 33, and was barely keeping up payments on her small two-bedroom home by working extra hours as a waitress. “There were times when I would lie in bed and think. I didn't know how I was going to pay that bill,” Mangano says.But she had a special ability for seeing the obvious thing. She knew how hard it was to mop the floor. “I was tired, of bending down, putting my hands in dirty water, wringing (拧) out a mop,” Mangano says. “So, There's gotta be a better way.”How about a “self-wringing” mop? She designed a special tool you could twist in two directions at once, and still keep your hands clean and dry. She set out to sell it, first a few at flea markets.Then Mangano met with the media. But would couch potatoes (电视迷) buy a mop? The experts on shopping TV were less than certain. They gave it a try, and it failed Mangano was sure it would sell if they'd let her do the on-camera display. She said, “Get me on that stage, and I will sell this mop because it's a great item.”So QVC, a multinational corporation specializing in televised home shopping, took a chance on her. “I got onstage and the phones went crazy. We sold every mop in minutes.”Today she's president of Ingenious Designs, a multimillion-dollar company, and one of the stars of HSN, the Home Shopping Network. Talking about the household invention, Mangano says, “It is as natural for me as it is for a parent to talk about their child.”8. What is the first paragraph mainly about?A. Mangano's small home.B. Mangano's work experience.C. Mangano's unhappy marriage.D. Mangano's hard living conditions.9. Mangano sold the mop successfully with the help of ________.A. HSNB.

HSN is a business organization that sells goods on the Internet.B. The experts on shopping TV were confident about Mangano's mop.C. Mangano got the idea of self-wringing mop from her own experience.D Mangano once had to work seven days a week to support her family.DI am a part of the Windward Robotics team known as the Omnicats, one of the many clubs offered at my school. My eight teammates and I started out by watching the robotics qualifiers and finals of Chinese teams. We used these robotics videos for inspiration and drew up mind maps of what our team wanted to do.We meet every day for two hours after school in order to build our robots. Typically, adultsoverseewhat students are building, but my school lets teens take control. It leaves room for more errors, but we're prouder of our final product.Before our first real match, a practice was offered at the actual site. My sub-team had been further along than other teams but quickly fell behind. When we arrived on that big day, I immediately felt my teammates' nervousness. Our first match was in three minutes. All of us glanced around at each other since we were not prepared at all. Our robot was still sitting in a box. Two of our teammates rushed to take the robot for an official examination as the rest of us discussed our strategy (策略).Our team captain explained that we all should try driving the robot now, while it was early in the season. She gave me the remote. I had only driven for a limited amount of time in practice so I was extremely nervous. Ourautonomous code (自动代码) beganto run almost immediately after our short discussion. Despite all the drama, we ended up winning the match.Not too bad for the first match! I was so proud. I did not enjoy the pressure of driving but liked building the robot behind the scenes instead.We have transferred to a different type of robotics at the end of the semester, which involves the whole team designing one giant robot with large tools. I am a part of the electrical team now, so I make sure the motherboard (母板) can supply the robot's energy needs. We have all enjoyed the rest of the season and learned that robotics it never dull!12. What does the underlined word in paragraph 2 probably mean?A. InspectB. AdmireC. OverlookD. Assume13. Why did her teammatesfed so nervous before first match?A. Because it was really too difficult for them.B. Because they didn't prepare for it at all.C. Because they didn't know what the match would be like.D. Because they didn't make full preparations before the match.14. How did the author feel about their first robotics match?A. It was tiring but exciting.B. It was stressful but wonderful.C. It was terrible but powerful.D. It was boring but professional15. What is the best title for the text?A. A Girl Who Loves RobotsB. My First Robotics MatchC. Teamwork for RobotsD. Robotics Is Never Dull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。
