2020年上海复旦大学附属中学国际部高三语文上学期期中考试试题及答案
2020年上海复旦大学附属中学国际部高三语文上学期期中考试试题及答案一、现代文阅读(36分)(一)现代文阅读I(9分)阅读下面的文字,完成下面小题。
社会是由众多家庭组成的,家庭和谐关乎社会和谐。
要在家庭中建立一种和谐的关系,就需要有家庭伦理。
中国自古以来就有维护家庭关系的种种伦理规范,它们往往体现在各种“礼”之中。
从《礼记》中可以看到各种礼制的记载,如婚丧嫁娶,这些都包含着各种家庭伦理规范,而要使这些规范成为一种社会遵守的伦理,就要使“礼”制度化。
在中国古代,“孝”无疑是家庭伦理中最重要的观念。
《孝经》中有孔子的一段话:“夫孝,天之经也,地之义也,民之行也。
”这是说“孝”是“天道”常规,是“地道”通则,是人们遵之而行的规矩。
为什么“孝”有这样大的意义?这与中国古代宗法制有关。
中国古代社会基本上是宗法性的农耕社会,家庭不仅是生活单位,而且是生产单位。
要较好地维护家庭中长幼尊卑的秩序,使家族得以顺利延续,必须有一套维护当时社会稳定的家庭伦理规范。
这种伦理规范又必须是一套自天子至庶人都遵守的伦理规范,这样社会才得以稳定。
“孝”成为一种家庭伦理规范,并进而成为社会的伦理制度,必有其哲理上的根据。
《郭店楚简·成之闻之》中说:“天登大常,以理人伦,制为君臣之义,作为父子之亲,分为夫妇之辩。
”理顺君臣、父子、夫妇的关系是“天道”的要求。
君子以“天道”常规处理君臣、父子、夫妇伦理关系,社会才能治理好。
所以,“人道”与“天道”是息息相关的。
“孝”作为一种家庭伦理的哲理根据就是孔子的“仁学”。
以“亲亲”(爱自己的亲人)为基点,扩大到“仁民”,以及于“爱物”。
基于孔子的“仁学”,把“孝”看成是“天之经”“地之义”“人之行”是可以理解的。
一方面,它体现了孔子“爱人”(“泛爱众”)的精义;另一方面,在孔子儒家思想中,“孝”在社会生活实践中有一个不断扩大的过程。
因此,“孝”不是凝固教条,而是基于“仁学”的“爱”不断释放的过程,只有在家庭实践和社会实践中,以“仁学”为基础的“孝”的意义才能真正显现出来。

Here is a list of some of the year’s biggest blockbusters so far.Kong: Skull IslandA reboot (重启) of King Kong would normally get laughed at in this day and age, but it looks like this modem version of the story will be worth watching. With US actress Brie Larson and UK actor Tom Hiddleston in the mix, this film is set to be this year’s biggest monster tale.Release Date:3/10/17Beauty and the BeastDirector Bill Condon is bringing back a part of our childhood in live action, complete with the songs we all remember and love. With British stars Emma Watson and Dan Stevens leading thecast, the classic Walt Disney story already sounds like it’ll be a delight for both children and adults.Release Date:3/17/17The Fate of the FuriousThere was doubt that we’d even get a Fast 8, especially after the fitting ending US actor Paul Walker’s character was given at the end of Furious 7. Fans thought they’d never see Dom and the rest of the crew back in action, but thankfully, US star Vin Diesel himself confirmed that The Fate of the Furious is fueling up for another go.Release Date:4/14/17Spider-Man: HomecomingSpider Man is heading home to Marvel Studios for the first time.

They enjoy culture, wine, history and nature, and the new Chinese tourists would also want to spend more money in Spain," said Cascales in a recent interview with Xinhua.“They are younger, more women travel and they are more cosmopolitan (见多识广的).They also travel on their own or in couples or in smaller groups. The old-fashioned large groups of visitors have not disappeared, but this new form of traveling is becoming more important,55he said.Speaking of the consumption pattern of the new kind of Chinese tourists, Cascales said, “The money they spend is distributed better because they will book one flight with one airline, the hotel with another company and the restaurant with another.” In his eyes, “Chinese tourists are very important because they combine two things: there are a large number of them and they spend more money than anyone else — almost four times more than tourists from other countries." They not only travel abroad in the summer months when Spain has to compete with the sun and beaches in countries such as Turkey and Egypt, but also travel in the off-peak seasons of a year, according to Cascales.In 2017, Spain is the second most popular tourist destination in the world, only after France. It attracted about 82 million visitors, 700,000 of them from China, a number which is estimated to rise to about 2.2 million by 2022.“We are ready; we have the infrastructure (基础设施) at every level, especially in hotel capacity. Here those visitors can find what they are looking for, including the luxury items which distinguish them,” Cascales noted.4. What are the features of the new Chinese tourists according to Cascales?A. They are cautious about spending money in Spain.B. They are likely to travel in smaller groups now.C. They are only interested in the sun and beach.D. They are mainly male visitors of middle age.5. What can we learn about the consumption pattern of new Chinese tourists?A. They will reserve flights and hotels with different companies.B. They will spend less money than tourists from other countries.C. They will travel abroad only during the off-peak seasons.D. They will spend the money in different cities.6. What is done to meet the demands of Chinese tourists?A. Local cultures in Spain are promoted.B. Well-furnished hotels are provided.C. Best and expensive items are offered for free.D. More shopping sites are constructed.7. What is the purpose of this text?A. To introduce the tourism industry of Spain.B. To show Spain's desire to attract Chinese tourists.C. To describe the features of Chinese tourists.D. To advertise Spain as a top tourist destination.CAs I work in theLarkwhistle Garden in Dyer's Bay, Ontario, I take my time and the garden is teaching me about working with the earth. I recognize that there will be both successes and failures and there are many variables(变量)that affect them both.The quality of the seeds planted has a bearing on how the plants will grow. The weather can be too hot, too cold, or exactly right, and usually varies between all three. Weeds seem to grow in the garden and need to be taken care of, pulled, and removed to ensure they do not eat into the fruits, vegetables, and flowers we have so lovingly planted.I take time to stand back and rest, and to observe the plants and how they are growing. Each plant is unique and develops in the way that is best for them. Some have large broad leaves to shadow their fruit from the severerays of the sun, while other plants are more open, their fruit needing the light to grow and ripen.Getting my hands dirty, feeling the sweat on my forehead, and the strength and flexibility of my body as I dig, bend and work under the warm summer sun, reminds me I am alive in ways I would not have remembered sitting on the couch.It is attractive to move things around, to transplant, and to disturb the natural order of how plants grow. The garden teaches me that it is important to know when to disturb things and when to let them be. The garden's life cycle follows a pattern that is repeated according to laws of nature, birth, growth, and then dies and it teaches us to accept this fact.8. How many variables may affect the growth of plants in the garden?A. Two.B. Three.C. Four.D. Five.9. What can we learn about the author?A. He feels exhausted while gardening.B. He enjoys life from working practice.C. He takes pleasure in harvesting fruits.D. He dreams away his time in the garden.10. How is the garden tended by the author?A. Its rank grass is got rid of.B. Its plants are left to grow freely.C. Its temperature is controlled properly.D. Its plants with large broad leaves are cut off.11. What fact does the author learn from gardening?A. Life takes its course.B. Hard work benefits health.C. Time is short and precious.D. Gardening brings good harvest.DA 10-year-old swimmer with sky-high dreams and a name to match them has broken a record previously held by Olympian Michael Phelps.Clark Kent Apuada, whose friends call him“Superman", swam the 100-meter butterfly in 1:09.38 at the Far Western Long Course Championships in his home state of California this Sunday. That's a second faster than the record Phelps set at the same event in 1995 with a time of 1: 10. 48 in the same category of boys under 10.Clark, a rising fifth-grader who is Filipino-American, told HuffPost he's been dreaming about breaking Phelps' record ever since he started swimming competitively at age 7."I was so motivated,"Clarksaid about his win."I was so happy that I was able to beat that record.”Phelps competed in his first Olympics at age 15. He went on to become the mostdecoratedOlympian in history, with 28 medals overall. “Everyone in the crowd was excited when they realized what a special swim they had just seen when we announced the long-standing record had been broken,"Cindy Rowland,Pacific Swimming's director, wrote in an email.Clarkwon first place for all the swimming events he competed in at this year's Far Western Championships. Pacific Swimming or PacSwim, a regional association that is part of USA Swimming, organizes the Far Western Long Course Championships. Cynthia Apuada,Clark' s mother,said that her child seems to be “living by his name at this point”。
2019-2020学年上海市复旦中学高三英语上学期期中考试试题及答案解析
2019-2020学年上海市复旦中学高三英语上学期期中考试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AThere have been many great painters in the rich history of Chinese art. Here are four of the greatest painters from China.Li Cheng (919—967, Five Dynasties and early Song Dynasty)Li Cheng contributed greatly to one of the golden ages of landscape paintings in world history. During his time, he was considered the best landscape painter ever. He is remembered especially for the winter landscapes he created and for simple compositions of tall, old evergreens set against a dry landscape. Several of his paintings are in thin ink which gives them a foggy appearance.Fan Kuan (990—1020 , Song Dynasty)Fan Kuan began his career by modeling Li Cheng's work but later created his own style, claiming that the only true teacher was nature. His finest workTravelers among Mountains and Streamsis a masterpiece of landscape painting and many future artists turned to it for inspiration.Qi Baishi (1864-1957)One of the greatest contemporary Chinese painters, Qi Baishi is known for not being influenced by Western styles like most painters of his time. He can be considered as the last great traditional painter of China. He painted almost everything from insects to landscapes. He is regarded highly in Chinese art for the freshness that he brought to the familiar types of birds and flowers, insects and grass.Wu Guanzhong (1919—2010)Widely considered as the founder of modern Chinese painting , Wu Guanzhong has painted various aspects of China, like its architecture, plants, animals, people and landscapes. Wu went on to combine Western and Chinese styles to create a unique form of modem art. In 1992, he became the first living Chinese artist whose work was exhibited at the British Museum.1.What do we know about Li Cheng?A.He loved landscape paintings.B.He copied many artists' work.C.His work gained worldwide recognition.D.He was considered as Fan Kuan's teacher.2.What is the main feature of Qi Baishi's paintings?A.They have foggy appearances.B.They lack diversity in the theme.C.They come under Western influence.D.They show advanced traditional painting skills.3.What did the four Chinese painters have in common?A.They were all modern painters.B.They all created landscape paintings.C.They were all impacted by Western art.D.They were all pioneers intraditional art history.BA male tiger was rescued in Mishan city, Northeast China's Heilongjiang province, on Friday. A tiger was recently seen on the Siner Russian border(边界),but there is no evidence to suggest this is the same tiger or that it had lost its way from Russia.Wherever it may have come from, cross-border protection of endangered species is a problem. According to Ma Jianzhang, a senior wild animal researcher in China, tigers know no borders, which have been built to stop humans from illegally crossing over. However, these borders also stop the free movement of tigers, thus preventing their breeding(繁殖)and exchange of genes.The Sino-Russian border alsocomes in the way ofprotecting tigers in the region. Data show about 500 to 550 Siberian tigers, or over 90 percent of the species, live in the wild in Russia; 27 live in the wild in China, and 50 inthe border region. Sometimes tigers lose their way across the border and that is hindering(妨碍)efforts to stop illegal hunting and protecting them.Fortunately, both China and Russia have realized this problem and are working toward solving it. As early as 2010, the two countries established a cross-border protection network aimed at strengthening communication on protecting tigers in the northeast. The countries have also held anti-poaching(反偷猎)activities together. In 2019, two national parks from the two countries signed a three-year deal to share research data on tigers, greatly improving the living conditions of Siberian tigers in the wild.However, much more needs to be done to protect the species. It is necessary to combine the tiger protectionareas in the two countries. That will require greater efforts from both sides and some difficulties might remain even then. Fortunately, both countries have been taking effective measures to provide the endangered species a better home.4. What's the original purpose of setting up the Sino-Russian borders?A. To ban people from illegal crossings.B. To help protect tigers in the region.C. To protect tigers from losing their way.D. To stop tigers' breeding and exchange of genes.5. What does the underlined phrase “comes in the way of” probably mean?A. keeps from.B. is on the way toC. is aimed atD. keeps up6. What is the focus of Paragraph 4 ?A. Recent studies and researches on tigers.B. Joint efforts by China and Russia to protect tigers.C. The possible effects of establishing a networkD. Reasons for improving the living conditions of tigers.7. What's the author's purpose in writing the text?A. To inform the possible dangers of tiger protection.B. To cover the news about a missing tiger on the border.C. To put forward suggestions on finding the missing tiger.D. To report the problems and measures of cross-border tiger protection.CMany of us in China enjoy adding chilies (辣椒) toour food, but did you know that this spicy vegetable could also be dangerous? A 34-year-oldUSman recently ended up in hospital after eating a Carolina Reaper—the spiciest chili in the world. After taking just a single bite of one, the man suffered from serious headaches in the following few days, reported BBC News.In fact, reports of stomachache and headache caused by eating spicy food are not something unusual. But if chilies are harmful, why is it that human beings are the only animals to eat this vegetable? According to the website Huanqiu, about 600 million Chinese people—almost half of the national population—are chili eaters. So what makes people love chilies so much? The human body reacts to the burning feeling that comes from eating chilies by releasing natural chemicals that “produce a sense of happiness” , noted BBC News.And the benefits go even further than just personal enjoyment. A survey conducted by the Chinese Academy of Medical Sciences found that the death rate of those who eat spicy food once or twice a week is 10 percent lower than those who eat it less than once a week. The number decreased to 14 percent for those who eat spicy food six to seven times a week. And another study done by theUniversityofVermontcame to a similar conclusion. “The data encourages people to eat more spicy food to improve health and reduce death risk at an early age,” Liu Qi, a nutritionist at the Harvard TH Chan School of Public Health, told BBC News.Chilies have anti-cancer quality and the ability to increase our metabolism (新陈代谢). So, don't worry if you love spicy food. It seems that chilies are actually good for us—except for the Carolina Reaper, perhaps.8. The example of a 34-year-old American is mentioned in Paragraph 1 to prove ________.A. chiliescan be beneficialB. chilies are popular inAmericaC. chilies can be dangerousD. serious headaches can be dangerous9. Eating chilies gives people a sense of happiness by_______.A. decreasing death rateB. releasing natural chemicalsC. curing serious headachesD. providing enough nutrition10. Which of the following statement is TRUE?A. Human are the only animals to eat chilies.B. Stomachache and headaches caused by chilies is something unusual.C. The more chilies you eat, the healthier you are.D. Chilies have anti-cancer quality but it can't increase our metabolism.11. The writer wrote the passage to ________.A. warn people of the dangers of chiliesB. ask people to eat Carolina ReaperC. encourage people to eat more chiliesD. tell people the benefits of chiliesDChina'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. The Tianwen-1 probe touched down at its pre-selected landing area in the southern part of Utopia Planitia, a wide plain on Mars, at 7:18 a.m.(Beijing Time), after three months scanning the whole planet on Mars docking orbit, the China National Space Administration(CNSA) announced.Tianwen-1, including an orbiter, a lander and a rover, was launched from the 'Wenchang Spacecraft Launch Site on the coast of southernChinas islandprovinceofHainanon July 23, 2020. It was the first step inChina'splanetary exploration of the solar system, with the aim of completing orbiting, landing and roving on the red planet in one mission. 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.12. What can we learn from the first two paragraphs?A. China is the only nation to launch a probe to Mars.B. Tianwen-1 landed in the northern part of the planet.C.

An electric car, though, is a much bigger investment. And batteries are its priciest component, representing around 30% of an average mid-size vehicle.To provide buyers with some peace of mind, carmakers guarantee their batteries, typically for eight years or around 200,000km. Producers, planning to go much further than that, though, are racing to launch “million mile”(1.6m kilometers) batteries. Contemporary Amperex Technology, a giant Chinese firm which produces batteries fora number of carmakers, was said to be ready to start producing batteries which would last for 16 years or 2m kilometres. Elon Musk has suggested that Tesla,a Californian maker of electric vehicles, has a million-mile battery in the works. And over in Detroit,General Motors is in the final stages of developing an advanced battery which it says has similar longevity (寿命)。

2019-2020学年复旦大学附属中学高三英语期中考试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AAmid the coronavirus outbreak, the U. S. Department of Homeland Security recommends having at least a two - week supply of water and food.PotatoesShelf life:2 to 5 weeks if stored in a cool, dry, dark placeYukon Gold, red, and fingerling potatoes will last from two to three weeks. Larger white potatoes can last for three to five weeks. Sweet potatoes have about the same shelf life. Don't store them next to onions, however. The two might go together well in cooking, but raw, each gives off gases and moisture that might cause the other to spoil faster.Tea※Shelf life:6 to 12 months past "sell - by" dateDried tea leaves, whether loose (in a sealed container) or in teabags (in an unopened box) can easily last a year or more if they' re not subjected to damp or humidity. However, the tea does tend to lose flavor over time.Peanuts● Shelf life:1 to 2 monthsPeanuts in their shell, especially when kept cool and dry, are perfectly happy in the cupboard for as long as two months.Canned fruits and vegetables● Shelf life:1 to 2 years past "sell - by” dateCanningis an extremely efficient means of preserving food. Generally speaking, if canned foods aren't subjected to extreme heat, their contents should stay good for two years or more. Be aware, however, of dented cans or those with swollen tops, which may indicate the presence of bacteria inside.1. Which can go bad faster if stored with onions?A. Potatoes.B. Tea.C. Peanuts.D. Canned fruits and vegetables.2. What is special about tea?A. The flavor of tea can always remain the same.B. Tea leaves are better to be preserved in an open jar.C. Tea leaves should be kept away from the state of being wet.D. The maximum length of time that tea can be stored is 6 months.3. What may shorten the "sell - by” date of canned foods ?A. Shapes of cans.B. Categories of foods.C. Decline of the temperature.D. Exposure to high temperature.BThe race skywards began inAmerica. In the late1800s, industrialization had driven urban populations and land prices up, making tall buildings increasingly cost-effective, according to Carol Willis, director of theSkyscraperMuseuminNew York, “The very first tall buildings were office buildings that concentrated a work force, piled one on top of the other in order to make business very efficient, ”she says.Like all major changes in architecture, the trend wasunderpinnedby engineering. The development of steel framework, which could be used instead of load-bearing stones, made it easier and cheaper to build tall. The coming of the elevator, meanwhile, made living on higher floors far more convenient.Though similar in shape, today's skyscrapers (摩天大楼) look little like those built in the first half of the 20thcentury. This is mostly thanks to architecture's next major technological shift:the curtain wall.Postwar developments in manufacturing meant that huge panes of glass could be produced quickly and uniformly, and glass windows soon became the front of choice for high-rises. As well as allowing for greater floor space and more natural light, glass exteriors (外部) help. buildings resist greater windloads.There are now 191 completed skyscrapers that are at least 300 meters tall. But that doesn't mean our cities will grow taller indefinitely. While each additional story adds sellable floor space, construction costs also rise. All buildings reach a point where adding an extra floor will cost more money than it brings.“Every city wants to have this landmark that gives that sense of distinct culture, ”but it also needs places for people to live and work in urban settings“without the city sprawling (无序扩张), ”explains Hong Kong architect Simon Chan.The next big challenge facing architects goes beyond height:At a time when buildings and their construction account for more than a third of the world's energy consumption and contribute about 40% of greenhouse gas emissions(排放), there are new costs to consider.Whether it's employing more energy-efficient materials, encouraging natural air or using buildingsthemselves to generate solar or wind energy, reducing carbon emissions is the new frontier for many skyscraper architects.4. What does the underlined word“underpinned” in paragraph 2 probably mean?A. Created.B. Prepared.C. Suggested.D. Supported.5. What made living on higher floors much more convenient?A. The development of steel framework.B. Load-bearing stones.C. The use of the elevator.D. The curtain wall.6. What can we know from paragraph 5?A. Our cities will grow taller definitely.B. All skyscrapers are at least 300 meters tall.C. Construction cost rises as the stories increase.D. The profit for builders will be greater as the building becomes higher.7. What's the next big challenge facing architects?A. How to build the greenest building.B. How to build the strongest building.C. How to build the tallest building in the world.D. How to build the most comfortable building.CIn a world simultaneously on fire and underwater thanks to climate change, scientists have announced some good news: Several important tuna (金枪鱼) species have stepped back from the edge of extinction.The unexpectedly fast recovery speaks to the success of efforts over the past decade to end overfishing. But tuna are not the only species scientists are discussing at the 2021 World Conservation Congress in Marseille, France, which is organized by the International Union for Conservation of Nature (IUCN). Researchers caution that many other marine species remainimperiled. For instance, more than a third of the world's sharks remain threatened with extinction due to overfishing, habitat loss, and climate change.“I think the good news is that sustainable fisheries are possible,” says Beth Polidoro, a marine biologist at Arizona State University. “We can eat fish in a proper way and without driving the population to the point where it is on the road to collapse or extinction."At the same time, she warned that the changes in status should not be an reason to catch as many fish as we want.The IUCN, which ranks the world's most endangered species on its Red List of Threatened Species and is backed by 16,000 experts across the globe, also announced at the meeting that some animals are moving in the other direction, onto the Red List. One notable example is the Komodo dragon, an island-living lizard at particular risk from climate change.For the better part of two decades, Polidoro has been part of a specialist group tasked with assessing the statuses of more than 60 species of tuna and billfishes for the IUCN.Her team announced its first comprehensive findings in 2011, mentioning that a number of commercially fished tuna species were dangerously close to disappearing.According to the new data, the Atlantic bluefin tuna (Thunnus thynnus), once listed as endangered, now qualifies for a status of least concern. As does the yellowfin tuna (Thunnus albacares) and albacore tuna (Thunnus alalunga), which were both considered near-threatened the last time they were assessed.8. What does the underlined word “imperiled” in paragraph 2 mean?A. EndangeredB. ConservedC. ExtinctD. Safe9. What can we infer from Polidoro's words?A. Too many fish are being eaten by human beings.B. Eating fish does not necessarily lead to its extinction.C. Fish species are on the edge of dying out if no action is taken.D. The situation of underwater species are changing for the better.10. Which of following statement is true according to the passage?A. Some Tuna species are wiped out by overfishing.B. Tuna are ranked as the world's most endangered species.C. Climate change poses a threat to most species in water and on land.D. Three tuna species have been saved from extinction according to the data.11. What's the main idea of the passage?A. Some tuna species are reported endangered recently.B. IUCN has helped saved a great many marine species.C. Improvement has been made in saving marine species.D. Great efforts should be made to conserve species underwater.DWatching what you eat can be easier said than done, but a recent study shows it might not just be about what'son your plate — it could be about how quickly it disappears.Japanese researchers followed 1,083 adultsfor five years, splitting them into three categories based on how quickly they ate: slow, normal, and fast. They also answered a questionnaire at the beginning of the study, sharing their diet, physical activity, and medical history. In the beginning, none of the volunteers had metabolic syndrome (新陈代谢综合征) - meaning at least three risk factors — which can lead to health problems like heart conditions and diabetes.When the participants reported back five years later 84 had been diagnosed (诊断) with metabolic syndrome — and their eating speed was a major predictor, according to the results in the journal Circulation. The fast eaters were 89 percent more likely to have metabolic syndrome than slow and normal eaters. Just 2.3 percent of slow eaters received the diagnosis, compared to 11.6 percent of fast eaters. But that's not all. Fast eaters also saw more weight gain, larger waistlines, and higher blood sugar levels than slow eaters.The researchers saygobblingmakes it easier not to take notice of fullness before your body has a chance to signal you to stop. “So when people eat fast they are more likely to overeat,” said Takayuki Yamaji, MD, study author and cardiologist at Hiroshima University in Japan in a statement.Previous research backs up the weight benefits of slow eating, too. One study of New Zealand women found fast eaters have higher body-mass indexes (指数), and a Chinese study found that both healthy and fat men ate less when told to chew 40 times instead of 15 times before swallowing. Initial research even suggests chewing your food longer could bum more calories - up to about 1,000 extra every month.12. What are the participants divided by?A. Medical history.B. Health condition.C. Physical activity.D. Eating speed.13. Which may be the result of the study?A. Fast eaters are 4 times more likely to have metabolic syndrome.B. Normal and slow eaters don’t have metabolic illness.C. 89% of fast eaters have higher blood pressure.D. Slow caters are healthier than fast eaters.14. What does the underlined word “gobbling” in Paragraph 4 best mean?A. Tasting slowly.B. Digesting quickly.C. Eating greedily.D. Cooking carefully.15. What does the last paragraph tell us?A. The importance of eating speed.B. The advantage of eating slowly.C. The result of a Chinese study.D. Fast eating and overeating.第二节(共5小题;每小题2分,满分10分)阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。

2019-2020学年上海复旦大学附属中学国际部高三英语期中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APeople in the Middle Ages did eat with their hands. Personal utensils (餐具) were mostly unheard of, especially forks. There were spoons to help serve, but only special guests would receive a knife from the host. Everyone else would be expected to bring their own. Of course, eating with one's hands can be quite a sticky situation, so towels were provided to help diners stay at least somewhat clean as they ate.Still, dining was often a messy affair. At special occasions in the wealthiest households, women tended to dine alone, separate from the men. Women were expected to uphold a quality of grace. Eating greasy meat by hand would certainly not help! Once the men and women had finished their meals, they would come together to socialize.Dietary scholars of the Middle Ages believed that the foods in a meal needed to be served and eaten in order of heaviness. The lightest and most easily digested foods, such as fruits and cheeses, were eaten first to help the digestive (消化) system get started. Once digestion was underway, greens and light meats, such as lettuce, cabbage and chicken, could be eaten. Last came the heavier vegetables and meats, such as carrots, beans, beef, pork, and mutton. This method was considered the most healthful way to eat.The main and largest meal of the day was supper, and it was eaten at midday. Dinner was a light meal, and many of those in nobility (贵族) -the highest levels of the Middle Ages society-skipped breakfast altogether. Breakfast was considered unnecessary for those who did not perform physical work. Snacks and any other eating during the day were viewed the same way. Commoners, or the working class, were allowed to eat breakfast and small meals throughout the day.1. What did people in the Middle Ages usually do at the dinner table?A. They cleaned hands before meals.B. They used personal utensils.C. They had to use knives at dinner.D. They ate mostly with hands.2. What is the third paragraph mainly about?A. The order of eating foods.B. The weight of various foods.C. The principles of digesting foods.D. The list of healthy foods.3. Why did the nobility avoid eating breakfast?A. Breakfast was wasted for the nobility.B. Breakfast was viewed as unnecessary.C. Breakfast was considered as a light meal.D. Breakfast was saved for commoners.BThe regular world presented to us by our five senses — you could call it reality 1.0 — is not always the most user-friendly. We get lost in unfamiliar cities; we meet people whose language we don’t understand. So why not try the improved version: augmented reality(AR)or reality 2.0 ? AR technology adds computer-produced images on the real world via a mobile phone camera or special video glasses.Early forms of AR are already here — smart phones can deliver information about nearby ATMs and restaurants and other points of interest. But that’s just the beginning. A few years from now the quantity of information available will have increased hugely. You will not only see that there’s a Chinese restaurant on the next block, but you will be able to see the menu and read reviews of it.This is where the next revolution in computing will take place: in the interface(界面)between the real world and the information brought to us via the Internet. Imagine bubbles floating before your eyes, filled with cool information about anything and everything that you see in front of you.Let’s jump ahead to ten years from now. A person trying to fix a car won’t be reading a book with pictures; he will be wearing a device that projects animated 3D computer graphics onto the equipment under repair, labelling parts and giving step-by-step guidance.The window onto the AR world can be a smart phone or special video glasses. But in ten years’ time these will have been replaced by contact lenses(隐形眼镜) with tiny LEDs, which present something at a readable distance in front of eyes. So a deaf person wearing these lenses will be able to see what people are saying.The question is, while we are all absorbed in our new augmented reality world, how willwe be communicating with each other?4. What is the text mainly about?A. The relationship between reality 1.0 and reality 2.0.B. Different forms of the AR technology.C. The next information technology revolution.D. The popularity of the AR technology.5. Which of the following will AR technology support according to the text?A. To pay for things online conveniently.B. To play online games merrily.C. To offer information efficiently.D. To communicate with others socially.6. What are Contact lenses with tiny LEDs used for?A. Show texts and images.B. Protect people’s eyes.C. Help deaf people communicate.D. Replace smart phone.7. What’s the author’s attitude towards the AR technology?A. Indifferent.B. Critical.C. Concerned.D. Favourable.CGetting rid of dirt, in the opinion of most people, is a good thing However, there is nothing fixed about attitudes to dirt.In the early 16th century, people thought that dirt on the skin was a means to block outdisease, as medical opinion had it that washing off dirt with hot water could open up the skin and let ills in. A particular danger was thought to lie in public baths. By 1538, the French king had closed the bath houses in his kingdom. So did the king ofEnglandin 1546. Thus began a long time when the rich and the poor inEuropelived with dirt in a friendly way. Henry IV, king ofFrance, was famously dirty. Upon learning that a nobleman had taken a bath, the king ordered that, to avoid the attack of disease, the nobleman should not go out.Though the belief in the merit(优点) of dirt was long-lived, dirt has no longer been regarded as a nice neighbor ever since the 18th century. Scientifically speaking, cleaning away dirt is good to health. Clean water supply and hand washing are practical means of preventing disease. Yet, it seems that standards of cleanliness have moved beyond science since World War II. Advertisements repeatedly sell the idea: clothes need to be whiter than white, cloths ever softer, surfaces to shine. Has the hate for dirt, however, gone too far?Attitudes to dirt still differ hugely nowadays. Many first-time parents nervously try to warn their children off touching dirt, which might be responsible for the spread of disease. On the contrary, Mary Ruebush, an Americanimmunologist(免疫学家), encourages children to play in the dirt to build up a strong immune system. And the latter position is gaining some ground.8. The kings ofFranceandEnglandin the 16th century closed bath houses because .A. they lived healthily in a dirty environmentB. they thought bath houses were too dirty to stay inC. they considered bathing as cause of skin diseaseD. They believed disease could be spread in public baths9. Which of the following best describes Henry IV’s attitude to bathing?A. CuriousB. AfraidC. ApprovingD. Uninterested10. How does the passage mainly develop?A. By following the order of time.B. By making comparison.C. By providing examplesD. By following the order of importance.111. What is the author’s purpose in writing the passages?A. To call attention to the danger of dirt.B. To introduce the history of dirt.C. To present the change of views on dirt.D. To stress the role of dirt.DDistinguished Baltimore artist John D. Ferguson died Sept 16. The Catonsville resident was 81.“His artist eye was in everything he did. His life was art and his family,” said Jennifer C. Jackson, who was Mr. Ferguson's friend for nearly three decades.” He was a lovable man who was always willing to talk about any topic he was interested in. At shows, people would go crazy for his work,” Ms. Jackson said. “He was also an enthusiastic sailor who loved nothing more than being on the water.” “His sculptures were just memorable,” said Mr. Lund, a Washingtonian. “I used to say, ‘Ferguson, I don't think you know how to do anything that is less than monumental.’”Mr. Ferguson earned a bachelor's degree in 1961 at Holy Cross University, where he developed an interest in painting. He served in the Army for two years until being discharged in 1963, and after studying briefly at the Boston Museum School, registered at the Chicago Art Institute, where he studied until 1966, when he entered the University of Illinois Chicago, where he obtained a bachelor's degree in 1966 in fine arts. Mr. Ferguson developed his interest and skills as a sculptor after moving to Baltimore to do further studies at the Maryland InstituteCollege of Art's Rinehart School of Sculpture, from which he graduated in 1971 with a master's degree in fine arts.“Over the years my work has moved gradually in the direction of elegance and simplicity,” Mr. Ferguson wrote in his artist statement. “Heavy, bulbous forms have been replaced by dancing, winglike forms. The welding process and respect for the qualities of the materials are interrelated and affect the final piece. “Most of the sculptures that are pictured in my works are made from steel, silicon bronze, and to Cor-Ten steel; shaped to create these beautiful and unique pieces of art. As you can see, my sculptures range in size anywhere from 12 inches to 30 feet or larger.”Through the years, his work found its way into such major public and private collections. “They encourage optimism, for they show strength and affirmation; there's nothing negative, depressing or anxiety-ridden about them”, wrote the late art critic John Dorsey in a 1997 exhibition review.12. What did Mr. Lund think of Ferguson?A. Likeable.B. Ordinary.C. Unwelcome.D. Interesting.13. What did Mr. Ferguson do first after serving in the army?A. He studied at the Boston Museum School.B. He got a bachelor's degree in fine arts.C. He entered the University of Illinois Chicago.D. He continued his studies at the Maryland Institute College.14. What influences the final sculptures?A. An even larger scale than before.B. The material comprised of metalsC. The shape of elegance and simplicity.D. Welding process as well as material quality.15.

2019-2020学年上海复旦大学附属中学国际部高三英语期中考试试题及答案第一部分阅读(共两节,满分40分)第一节(共15小题;每小题2分,满分30分)阅读下列短文,从每题所给的A、B、C、D四个选项中选出最佳选项AThe “laugh out loud” face is officially the world’s most popular emoji, according to researchers from Adobe (ADBE) who surveyed 7,000 users across the United States, the United Kingdom, Germany, France, Japan, Australia, and South Korea.The “thumbs up” emoji came in second, followed by the “red heart” emoji. The flirtatious “wink and kiss” and “sad face with a tear” emojis respectively rounded out the top five.The software maker on Thursday released the findings from its 2021 Global Emoji Trend Report ahead of World Emoji Day on Saturday.Adobe’s latest Emoji Trend report also examined the three most misunderstood emojis in the world. The “eggplant” symbol edged out the “peach” and the “clown” emojis respectively as the most confusing for users.The vast majority of emoji users (90%) believe the modern —day hieroglyphs make it easier for them to express themselves. Eighty — nine percent of respondents said emojis simplify communicating across language barriers. And 67% said they think people who use emojis are friendlier, funnier and cooler than those who don’t. A slight majority of respondents said they are more comfortable expressing emotions through emojis than talking on the phone or in —person. More than half of global emoji users (55%) said using emojis in communications has positively impacted their mental health. Seventy — six percent of those surveyed said emojis are an important communication tool for creating unity, respect and understanding. And 88% said they feel more empathetic toward people who use emojis.1.What are the three most popular emojis according to the passage?A.clown thumbs up laugh out loudugh out loud thumbs up wink and kissugh out loud thumbs up red heartD.thumbs up red heart sad face with a tear2.Which emoji is the most confusing one for users?A.Peach.B.Eggplant.C.Clown.D.Wink and kiss.3.Which of the following best describes the attitude of most people surveyed to emojis?A.Favorable.B.Passive.C.Indifferent.D.Doubtful.BA company called Neuralink has shared a video which appears to show a monkey playing a video game, but what makes the video even stranger is that themonkey is playing the video game with just its mind.Neuralink is a company owned by Elon Musk, which is working to develop devices that could allow people to control things using just their brains. The monkey in the video is called Pager, having special "Link" devices inside his brain. These devices are connected to 2,048 wires which lead to the parts of Pager's brain that control movements of the arms and hands.Scientists taught Pager to play a video game using a banana juice as a reward when he playedthe game correctly. Soon Pager was eager to play well in order to get more smoothie. At first, Pager controlled the video game using a joystick (操纵杆). But as Pager played, his Link devices wirelessly sent out information about the signals his brain was using to control his arms and hands. Neuralink's scientists recorded all of these signals.Then they used computers to match up the signals from Pager's brain to the movements that his hands were actually doing. This was challenging work and the scientists counted on artificial intelligence (AI) to help them decode (解码) Pager's brain signals.The next step was to have a computer make moves in the video game as if Pager had actually moved the joystick. If Pager thought about moving the joystick up, the computer would send an "up"signal to the video game. Thus Pager was able to play the video game using just his brain.When people are paralyzed (瘫痪的), it's often because the brain has lost the ability to send signals to nerves and muscles in certain parts of the body. Neuralink hopes that one day, its system will be ableto send this information in a different way, allowing paralyzed people to use their arms or legs again.4. What does Neuralink aim to do?A. To make monkeys much smarter.B. To solve complex problems with monkeys.C. To create a device linking monkeys and people.D. To make people control things with their brains.5. How does the author introduce the process of the research?A. In order of time.B. By making a comparison.C. By giving examples.D. In order of space.6. What played an important role in the success of the research?A. The joystick.B. Artificial intelligence.C. The video game.D. The banana smoothie.7. Which is the most suitable title of the test?A. Neuralink Posts an Unusual VideoB. Disabled People Have a Bright FutureC. Monkey Plays Video Games with His MindD. Neuralink, a Creative and Competitive CompanyCAt the age of 50, Nina Schoen expects to have a long lifeahead of her, but has thought a lot about death—and why people are so reluctant to talk about it: “It’s going to happen to all of us,” she says, “but it should be a more positive experience than the fear we put into it.”When she first heard about a new end-of-life process that turns the body into compost (堆肥), “I was really moved by the idea,” says Schoen, who became one of the first to reserve a spot with a Seattle-based company called Recompose, the county’s first funeral home to offer human composting.Last year Recompose began transforming bodies to soil, more formally known as natural organic reduction. Before that, end-of-life options in the U.S. were limited to burial or cremation (火化), both of which come with environmental costs—U.S. cremations alone dump 1.7 billion pounds of carbon dioxide into theatmosphere every year.Katrina Spade pioneering the composting movement has spent a decade developing the process in hopes of offering people a greener option for death care. “I wondered, ‘What if we had a choice that helps the planet rather than harms it?’” Spade tells PEOPLE. “To know that the last gesture you’ll make will be gentle and beneficial and it just feels like the right thing to do.”After she had her own two sons, she began to wonder what she might do with her body after death. A friend who knew her interest in the topic reminded her that farmers sometimes compost the body of cows, and thatsparkedan idea for her theory: “If you can compost a cow, you can probably compost a human,” she thought, and she set about designing a facility to do just that.“This is about giving people another choice,” Spade says. “At first, people react with shock—‘You really can do that?’ But so many people today are looking at their impact on the Earth. This is a popular thing because when you die, you can give back to the planet.”8. How do people react when it comes to death according to paragraph 1?A. They are unwilling to comment.B. They can face it without fear.C. They feel it a positive experience.D. They would like to compost their bodies.9. What can we know about the company Recompose?A. Its CEO is Katrina Spade.B. It is located in Seattle.C. It was founded to resist cremation.D. It has spent 10 years composting bodies.10. What does the underlined word “sparked” probably mean?A. Changed.B. Compromised.C. Quitted.D. Inspired.11. What message does the author seem to convey in the text?A. A little things in our life can bring in big outcomes.B. We human beings should do all we can to help the earth.C. Composting is so popular that we should reserve a spot soon.D. We should reject burial because of its harm to environment.DMy 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 thehigh 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.12. 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.13. 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. Extremely generous to others.14. Compared with hotels, what is the writer's favorite of the Airbnb accommodation?A. It is cheaper in most cases.B. It supplies a better living condition.C. It offers a much safer accommodation.D. It provides a chance to know local culture.15. What does the author think of finding accommodation on Airbnb?A. Disapproving.B. Supportive.C. Neutral.D. Doubtful.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。

The government said the state of emergency — set to last for about two weeks— would be “short and powerful”. Under the measures, bars will be required to close and big sporting events will be held without audience. The government has insisted that the Olympics will go ahead in July.Prime minister Yoshihide Suga announced the measures on Friday, saying they would begin on Sunday and remain in place until 11 May. In addition to to Tokyo, Osaka, Kyoto and Hyogo will be affected. It has marked the third state of emergency in japan since the pandemic began. “I sincerely apologize for causing trouble for many people again,” he said. “It is feared that infection in major cities will spread across the whole country if we take no measures.”Under the rules, major facilities like department stores will close, as well as restaurants, bars, and KTV rooms serving alcohol. Restaurants that do not serve alcohol are being told to close early, and companies are being asked to make arrangements for people to work remotely. Schools will remain open. Besides, the emergency measurescoincide withthe country’s “Golden Week” holiday, which runs from late April to the first week of May and is the busiest travel period of the year. Tokyo governor Yuriko Koike urged residents to start taking precautions immediately. In an effort to discourage people from going out at night. She said neon signs (霓虹灯) would be turned off.The coronavirus toll in Japan has been much lower than that in many other countries, with about 558,000 cases and fewer than 10,000 deaths, according to figures collected by Johns Hopkins University. But there areconcerns over the latest rise in infections, with reports of hospital bed shortages in some areas.Tokyo 2020 president Seiko Hashimoto said at a news conference on Friday that organizers were not considering canceling the event. “I hope the coronavirus situation improves with the prevention measures the government, Tokyo, and other regional governments have put into place,” she said. “We, as Tokyo 2020, continue to wish for the swift return to normal and will continue to work closely to make sure a safe and secure Olympics can happen.”4.

What does the underlined phrase “coincide with” in Paragraph 3 mean?A. meet withB. deal withC. make upD. set upCIn the summer of 2016, I gave a talk at a small conference in northernVirginia. I began by admitting that I’d never had a social-media account; I then outlined arguments for why other peopleshould consider removing social media from their lives. The event organizers uploaded the video of my talk to YouTube. Then it was shared repeatedly on Facebook and Instagram and, eventually, viewed more than five million times. I was both pleased and annoyed by the fact that my anti-social-media talk had found such a large audience on social media.I think of this event as typical of the love-hate relationships many of us have with Facebook, Instagram, and other social-media platforms. On the one hand, we’ve grown cautious about the so-called attention economy, which, in the name of corporate(公司的) profits, destroys social life gradually and offends privacy. But we also benefit from social media and hesitate to break away from it completely. Not long ago, Imet a partner at a large law firm in Washington, D.C., who told me that she keeps Instagram on her phone because she misses her kidswhen she travels; looking through pictures of them makes her feel better.In recent months, some of the biggest social-media companies, Facebook and Twitter, in particular, have promised various reforms. In March, Mark Zuckerberg announced a plan to move his platform toward private communication protected by end-to-end encryption(端对端加密); later that month, he put forward the establishment of a third-party group to set standards for acceptable content.All of these approaches assume that the reformation of social media will be a complex, lengthy, and gradual process. But not everyone sees it that way. Alongside these official responses, a loose collective of developers that calls itself the IndieWeb has been creating another alternative. They are developing their own social-media platforms, which they say will preserve what’s good about social media while getting rid of what’s bad. They hope to rebuild social media according to principles that are less corporate and more humane(人道的).8. Why did the author feel annoyed when his video was spread online?A. His video caused many arguments.B. His video was shared without his permission.C. His talk was opposed by a large amount of people.D. His video’s popularity on social media is against his talk.9. Why does the author mention the story of his partner in paragraph 2?A. To prove that social media has some benefits.B. To advise people to break away from social media.C. To tell the negative effects social media may produce.D. To describe people’s complicated relationships with social media.10. What is the purpose of the reform made by some social-media companies?A. To attract more users.B. To improve network environment.C. To make more profits.D. To provide more convenientservice.11. What does the IndieWeb intend to do?A. Develop new social-media platforms.B. Remove social media from people’s lives.C. Improve the existing social-media principles.D. Help social-media companies to make reformation.DA world in which extinct creatures could be brought back to life came a step closer yesterday. Australianscientists have managed to extract a gene from a preserved sample of a Tasmanian tiger and make it active. Thebreakthroughhas left them dreaming that one day they will be able to recreate the animal, which died out more than 70 years ago. And if it can be done with the Tasmanian tiger, it may also be possible to resurrect (复活) creatures that have been extinct for far longer.“There used to be a time when extinction meant forever, but no more, ” said Professor Mike Archer. “We are now able to seriously challenge whether those animals that have gone for ever. What has been achieved is a very important step in bringing back those animals that are extinct. And while I think that technically it is still pretty difficult at the moment, we can now see the possibilities. I’m personally convinced that the Tasmanian tiger will be brought back to life in my lifetime.”The breakthrough came after nine years of experiments by scientists at the University of Melbourne, who extracted a gene from one of several tigers preserved in alcohol in a Melbourne museum. They removed the equivalent gene from a mouse embryo implanted the tiger gene and then watched as the mouse continued to grow normally, suggesting the tiger gene had been activated.Team leader Dr. Andrew Pask said it was the first time DNA from an extinct species had been used to “induce (引起) a functional response in another living organism”.However, the animal’s entire gene structure would have to be revived in the same way to even begin the possibility of bringing the Tasmanian tiger back from the dead.Mick Mooney, a wildlife officer ofthe Tasmanian Government, was worried that such developments could encourage people’s indifference to the protection of endangered species.“If people think that we can bring animals back to life after they’ve gone, they will start saying that there is nothing to worry about because we can fix it up later.”12. What does the underlined word “breakthrough” in the l paragraph refer to?A. Scientists have recreated new animals.B. Scientists have resurrected endangered animal.C. It has turned out that some creatures would not go extinct.D. A tiger gene has been extracted successfully and activated.13. Scientists are carrying out the experiments in order to ________.A. bring extinct animals back to lifeB. transplant the genes of tigers into other animalsC. find out what factors lead to the animals’ extinctionD. find a new way to extract animals’ DNA14. Mike Archer thinks that ________.A. scientists now have no technological difficulty reconnecting extinct animalsB. it’ll be a century or so before a Tasmanian tiger walks on the earth againC. humans have come closer in reconnecting extinct animalsD. reconnecting extinct animals is impossible15. We can learn from Mick Mooncy’s words that_________.A. he thought it unnecessary to worry about endangered animalsB. his opinion is in contrast with that of the Tasmanian GovernmentC. he thought people should be encouraged to protect endangered animalsD. he is concerned that bringing extinct animals back to life may have a negative effect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。

Players aged between eight and 18 can compete in the new event; information about where and when it will be held will be released later.Barbasol Junior ChampionshipBeginning the career in the PGA Tour is something that a junior golfer tends to dream of. The Barbasol Junior Championship, which is scheduled to take place between June 29 and July 2 at Keene Trace Golf Club inNicholasville,Kentucky, will provide such an opportunity.

The group warns the condition of the world's animals is worse than its earlier reports showed, indicating worldwide action is needed.The WWF is worried about the loss of and damage to Earth’s environment. The report provides information about more than 10,000 animal populations from 1970 to 2010. These populations are called “vertebrate species,” or animals with backbones — like fish, birds, mammals, amphibians and reptiles. The report shows these populations have dropped by 52 percent in just 40 years. It warns freshwater species have fallen by 76 percent, which is almost twice the loss of land and ocean species. Most of these losses are in the tropics, with the biggest drop inLatin America.Marco Lambertini, the WWF’s International Director-General said, “This is about losing natural habitats. This is aboutconvertingforests, grasslands, and wetlands into agriculture mainly, and it is about unsustainable use of wildlife. Illegal hunting has been actually increasing over the last 10 years, which definitely a driving force for extinction, particularly of large species.”The report also notes what it calls the world’s “Ecological Footprint”, that is, the effect of human activities on the planet. Mr. Lambertini says there has been an increase in carbon dioxide gases and the pouring of nitrogen into oceans and rivers from fertilizers used in agriculture, which certainly cannot continue.“We are consuming on average every year about the equivalent of about 1.5, one and a half times the resources available to the planet. That means we are cutting trees more quickly than they can be restored. We are fishing the oceans more quickly than fishing stocks can reproduce, and we are emitting in the atmosphere more CO2than the natural systems can actually absorb, which is clearly not sustainable.”Mr. Lambertini warns climate change affects almost everyone on the planet and that whole species may disappearif the world does not reduce the effects of humans on the climate.4. According to the passage, what kind of species faces the biggest drop in population?A. Land and ocean species.B. Animals with backbones.C. Freshwater species inLatin America.D. Freshwater species in the tropics.5. All the following can contribute to the loss of world’s wildlife population EXCEPT ________.A. turning wildlife habitats into agriculture land.B. making sustainable use of wildlife.C. hunting illegally.D. emitting CO2 gases and pouring nitrogen.6. Which does the underlined word “converting” in paragraph 4 mean?A. Conserving.B. Conveying.C. Exchanging.D. Transforming.7. It can be inferred from the passage that _______.A. Marco is much concerned about human’s current behaviors towards wildlife.B. what the planet provides now can satisfy human’s sustainable development.C. more than half of the world’s wildlife population has been lost.D. if humans reduce the effects on the climate, the whole species will not disappear.CThere are similarities and differences between high school life and college life.For one thing, there are several similarities between high school life and collegelife. First, the most important task in high school and college is both studying. Studying is the most important as a student. Second, we need a goal to fight for in both high school life and college life. To lead a meaningful life, we have to set up a goal to achieve.For another, there are also some differences between high school life and college life. First, our studying is also the biggest difference. In high school, we are required to follow our teachers' steps and finish theirassignmentsevery day. While in college, there are no teachers giving such detailed requirements to us and we can choose study or not according to our own willing. What and how to study totally depends on us. Therefore, the ability of self-control is very important in college life. Second, the flexibility (灵活性) of time is anotherdifference. In high school, we have no much leisure except for our time of study. However, in college, we have much controlled by ourselves except the time of classes. And we have more time to do what we like. Finally, college lifeis much more various and richer. Besides study, we can attend many other activities, which make our college life more wonderful.In brief, there are both similarities and differences between high school life and college life. However, no matter we are in which period, we need to make full use of every day so that we will never feel regretful.8. Why do students need a goal to fight in high school and college?A. To enter a good college.B. To avoid living a meaningless life.C. To develop the ability of control.D. To meet their parents’ satisfaction.9. What does the underlined word “assignments” in paragraph 3 probably mean?A. Projects.B. Tasks.C. Goals.D. Dreams.10. Which is the correct structure of the passage?A. ①-②③-④B. ①②-③-④C. ①-②③④D.①②-③④11. Which of the following can be the best title for the text?A. College LifeB. High School LifeC. High School and CollegeD. High School Life and College LifeDThere is nothing ordinary about this little boy's adorable experience with his musical heroes.5-year-old Taylor Hooper was just one of the 35,0000people who were attending the Foo Fighters concert in Belfast, Norther Ireland last week. Not only is the American rock group his favorite band, it was also his first ever concert.Taylor's mother, Nikki Hooper, says that she and her husband have always been huge fans of the Foo Fighters. In addition to traveling far and wide to see their shows, they even named their son after the drummer, Taylor Hawkins. So when the band played in their home city, they decided it was finally time for their son to see their beloved rock and rockers in concert.“He's been listening to them since he was born — mainly because his dad and I are super fans.” Mrs Hooper told BBC. “We called the event organizers and they said it would be no problem, but that we should know it would be a loud music event, so we gotTaylorsome special headphones. When we got there everyone was so welcomingto him.”Throughout the show, the audience continuously madeTaylorand his parents move closer to the stage. Furthermore, Mrs. Hooper helped her son stand out from the crowd by making him a sign that said he was a 5-year-old attending his first concert.When Foo Fighters front man Dave Grohl finally saw the sign and read it aloud into the microphone, the crowd began chanting for them to bring the youngster onto the stage. That's exactly what he did. When the stage managers brought the boy to the stage, Grohl asked Taylor to show the crowd how to dance.The small boy then danced to the whole song, making him an “Inter net wonder”.Taylordidn't just walk away from the show with memories, either;the band also invited him backstage to give him a number of gifts, includinga pair of Taylor Hawkins's drumsticks.12.

2020年上海复旦大学附属中学国际部高三英语上学期期中考试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ALocated besideLake Geneva, the Olympic Museum houses more than 10,000 artificial objects and hours of interactive contents highlighting some of the best moments during the Olympics. Here are some of the museum’s most moving moments.The Olympic ParkThe journey through the Olympic Museum begins in the Olympic Park, an 8,000-square-meter outdoor area in front of the museum overlooking Lake Geneva and theAlps. The park contains artwork and sculptures that show respect to the world of sport.The first Olympic SymbolThe “Olympic Rings” flag was designed by Coubertin in 1913. The rings represent the five continents that participate in the Olympics: Africa, Asia,America,AustraliaandEurope. The six color1 s include at least one color1 that is represented on the flag of every country.The StadiumsThe stadiums that host the Olympic Games are as much of a celebration of design as the games are a celebration of sportsmanship. Guests can explore plans and models of Olympic stadiums’ past and present, including one of the games’ most attractive stadiums, the Bird’s Nest from Beijing 2008 Olympics.The Olympic MedalsHave you ever wondered what an Olympic medal looks like? The Olympic Museum has a room that houses every bronze, silver, and gold medal from every Olympic Games dating back to the first modern Olympics of 1896. Each medal design is a unique representation of the year and location in which the games were held.1.Which moment do you see first when exploring the Olympic Museum?A.The Olympic Park.B.The first Olympic Symbol.C.The Stadiums.D.The Olympic Medals.2.What can you do in the section of The Stadiums?A.Celebrate the glory of a sportsman.B.Meet the designers of the stadiums.C.Explore the future stadiums.D.Enjoy the model of the Bird’s Nest.3.In which column of a newspaper may this text appear?A.Entertainment.B.Science.C.Travel.D.Business.BBritish anthropologists (人类学家) Russell Hill and Robert Barton of the University of Durham, after studying the results of one-on-one boxing, tae kwon do, Greco-Roman wrestling and freestyle wrestling matches at the Olympic Games, conclude that when two competitors are equally matched in fitness and skill, the athlete wearing red is more likely to win.Hill and Barton report that when one competitor is much better than the other, colour has no effect on the result. However, when there is only a small difference between them, the effect of colour is enoughtipthe balance. The anthropologists say that the number of times red wins is not simply by chance, but that these results are statistically significant.Joanna Setchell, a primate (灵长目动物) researcher at the University of Cambridge, has found similar results in nature. She studies the large African monkeys known as mandrills. Mandrills have bright red noses that stand out against their white faces. Setchell’s work shows that the powerful males — the ones who are more successful with females — have a brighter red nose than other males.As well as the studies on primates by Setchell, another study shows the effect of red among birds. In an experiment, scientists put red plastic rings on the legs of male zebra finches and this increased the birds’ success with female zebra finches, Zebra finches already have bright red beaks (鸟喙), so this study suggests that, as with Olympic athletes, an extra flash of red is significant. In fact, researchers from theUniversityofGlasgowsay that the birds’ brightly coloured beaks are an indicator of health. Jonathan Blount, a biologist, andhis colleagues think they have found proof that bright red or orange beaks attract females because they mean that the males are healthier. Nothing in nature is simple, however, because in species such as the blue footed booby, a completely different colour seems to give the male birds the same advantage with females.Meanwhile, what about those athletes who win in their events while wearing red? Do their clothes give them an unintentional advantage? Robert Barton accepts that “that is the implication” of their findings. Is it time for sports authorities to consider new regulations on sports clothing?4. According to their research. Hill and Barton conclude that ________.A. the colour of clothing has an effect on most sport eventsB. red should be the choice of colour for clothing in sportsC. red plays a role when competitors are equally capableD. athletes perform better when surrounded by bright red5. The underlined word “tip” in Paragraph 2 is closest in meaning to ________.A. achieveB. advanceC. keepD. change6. The example of the blue footed booby proves that ________.A. male birds use different body parts to draw attentionB. red is not the only colour to attract female birdsC. blue gives female birds the same advantageD. blue can indicate how healthy a bird is7. What can be inferred from the passage?A. The colour red gives male animals the most advantage.B. Male zebra finches prefer to have red plastic rings on their legs.C. Rules on sports clothing are going to be changed.D. Athletes wearing red may have an advantage over their opponents.CFlying someone one-way fromLondontoNew Yorkproduces nearly a ton ofcarbon dioxide or CO2. That's alot of this climate-warming greenhouse gas. But there are ways to cut the climate impact of flying, one of which is to ask planes to surf high-altitude winds every chance they get.It's not something they've been allowed to do. But that may change—and soon.Most jets crossing the Atlantic Ocean follow one of several fixed paths that are widely spaced because radar (雷达) had not been able to track aircraft everywhere above the Atlantic. But a new network of satellites could soon change that.Wells was part of a team inEnglandthat calculated the fastest possible routes for passenger planes. According to them , traveltime a plane takes when flying across theAtlanticvaries with the winds that a plane meets. For instance, eastbound (向东的) flights can get a powerful push. Westbound routes miss that benefit. Faster flights burn less fuel. And less burning gives off fewergreenhouse gases.The airline industry knows it has a high " carbon footprint." But it takes decades and many billions of dollars to design, test and fly new planes. Changing a flight path, in contrast, can cut costs and energy right away.The new study doesn't show how well such wind surfing would work for all planes, in all skies and the worldover. Bui it does suggest that making flight routes more flexible could cut both fuel use and CO2in some places.However, if flight times vary depending on the wind, scheduling connecting flights and managing runways and gates would become more complicated. The researchers would have to work out the best flight paths that take such scheduling issues into consideration. They may also want to see if flying at different altitudes gives a wider choice of flexible routes at the times most people want to fly.National Air Traffic Services (NATS) which provides air-traffic control for theUnited Kingdomsaid it would temporarily disband its flight-paths system and work to allow airlines to choose flexible routes that would best limit their fuel use.8. What happens to east bound flights when crossing theAtlantic?A. They consume more fuel.B. They use less time and energy.C. They produce more greenhouse gases.D. They are against a stronger wind.9. What should be done to make adopting flexible flight routes possible?A. Calculating the flight time.B. Finding the best flight paths.C. Adjusting the size of jets.D. Adding more runways and gates.10. Which word can best replace the underlined word "disband” in the last paragraph?A. Stop.B. Copy.C. Handle.D. Restore.11. What can we infer from the text?A. Planes are producing the most carbon dioxide.B. New fuel is benefiting airline industries greatly.C. Carbon footprint is a serious problem in theUK.D. Surfing the winds can make air travel greener.DIdentifying the chemical makeup of pigment (色素) used in ancient documents, paintings, and watercolor1 s is criticalto restoring and conserving the precious artworks. However, despite numerous efforts, scientists had been unable to determine the source of folium, a popular blue dye used to color1 manuscripts (手稿) in Europe during the middle ages — from the 5th to the 15th century. Now, a team of researchers fromPortugalhas finally uncovered the mysterious ingredient responsible for the gorgeous blueish-purple color1 that helped bring ancient illustrations and texts to life.The research team began byporing overinstructions penned by European dye makers from the 12th, 14th, and 15th centuries. They found what they were seeking in a 15th-century text entitledThe Book on How to MakeAll the Color Paints for Illuminating Books. However, translating the instructions was no easy task. It was written in the now extinct Judaeo-Portuguese language, and though the source of the dye was traced back to a plant, no name was mentioned.However, by piecing together suggestions from the text, the scientists were able to determine that the dye was made from the bluish-green berries of the chrozophora tinctoria plant. After an extensive search, the team found a few varieties of the plant growing along the roadside near the town ofMonsarazin southPortugal.The detailed instructions gave the researchers critical clues — including the best time to pick the berries. “You need to squeeze the fruits, being careful not to break the seeds, and then to put them on linen (亚麻).” The scientist says the detail was important since broken seeds polluted the pigment, producing an inferior quality ink. The dyed linen, which was left to dry, was an efficient way to store and transport the pigment during ancient times. When needed, the artist would simply cut off a piece of the cloth and dip it with water to squeeze out the blue color1 .Once the key ingredient had been identified, the researchers began to determine the dye’s molecular structure. To their surprise, they found that folium was not like any other known permanent blue dyes — it was an entirely new class of color1 , one they named chrozophoridin. “Chrozophoridin was used in ancient times to make a beautiful blue dye for painting.” the team wrote in the study. “Thus, we believe that this will not be our final word on this amazing plant and its story and that further discoveries will follow soon.”12. The primary purpose of the study is to ________.A. restore and conserve ancient precious artworksB. determine the substance making up the foliumC. prove the ancient dye-making technique was organicD. identify which class of color1 folium belongs to13. The underlined phrase “poring over”in the second paragraph means ________.A. discussing publiclyB. testing repeatedlyC. passing directlyD. reading carefully14. What can be learned about the blue dye folium?A. It was essentially an inferior type of ink.B. It was the only kind made from wild berries.C. It could be carried and used easily.D. It was carefully squeezed from broken seeds.15. The article is mainly about _________.A. how the mystery ofa thousand-year-old blue dye was solvedB. why the researchers took the trouble to recreate the dyeC. what needs to be done to make an organic dye from a plantD. when and where the discovery of the dye was made第二节(共5小题;每小题2分,满分10分)阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。

They made baskets three feet in diameter and othersno bigger than a thimble (顶针). The Pomo people were masters of decoration. Some of their baskets were completely covered with shell pendants;others with feathers that made the baskets’ surfaces as soft as the breasts of birds. Moreover, the Pomo people made use of more weaving techniques than did their neighbors. Most groups made al their basketwork by twining--the twisting of a flexible horizontal material, called a weft, around stiffer vertical strands of material, the warp. Others depended primarily on coiling-a process in which a continuous coil of stiff material is held in the desired shape with tight wrapping of flexible strands. Only the Pomo people used both processes with equal ease and frequency. In addition, they made use of four distinct variations on the basic twining process, often employing more than one of them in a single article.Although a wide variety of materials was available, the Pomo people used only a few. The warp was always made of willow, and the most commonly used weft was sedge root, a woody fiber that could easily be separated into strands no thicker than a thread. For color1 , the Pomo people used the bark of red-bud for their twined work and dyed bullrush root for black in coiled work. Though other materials were sometimes used, these four were the staples in their finest basketry.If the basketry materials used by the Pomo people were limited, the designs were amazingly varied. Every Pomo basket maker knew how to produce from fifteen to twenty distinct patterns that could be combined in a number of different.4. The word “fashion” in paragraph 1 is closest in meaning to ______.A. maintainB. organizeC. tradeD. create5. What is the author's main point in paragraph 2?A. The neighbors of the Pomo people tried to improve on the Pomo basket weaving techniques.B. The Pomo people were the most skilled basket weavers in their region.C. The Pomo people learned their basket weaving techniques from other Native Americans.D. The Pomo baskets have been handed down for generations.6. According to the passage, the relationship between red-bud and twining is most similar to the relationship between ______.A. bullrush and coilingB. weft and warpC. willow and feathersD. sedge and weaving7. Which of the following statements about Pomo baskets can be best inferred from the passage?A. Baskets produced by other Native Americans were less varied in design than those of the Pomo.B. Baskets produced by Pomo weaves were primarily for ceremonial and religious purposes.C. There were a very limited number of basket-making materials available to the Pomo people.D. The basket-making production of the Pomo people has been increasing over the years.CWe all use different ways to remember ideas, facts and things we need to store. Remembering is an extremely important part of our learning experience. Information process, storage and recall encourage purposeful learning.But the brain doesn’t store everything we want or need for future use. It makes choices and tends to remember information that forms a memorable pattern. Things you learned recently can be particularly difficult to remember because they haven’t taken root in your mind.“Forgetting allows us to remember what is really important to our survival. We forget much of what we read, watch, and think directly every day.” writes John Medina in his book, Brain Rules.How do you avoid losing 90%of what you’ve learned? An inspiring writer and speaker Zig Ziglar once said: “Repetition is the mother of learning, the father of action, which makes it the architect of accomplishment.”Repetition has been a remembering skill for ages. When you hear or read something once,you don’t really learn it-at least not well enough to store the new information for long. The right kind of repetition can do wonders for your memory. People learn or remember better by repeating things or getting exposed to information many times. Othersrepeat particular steps or processes deliberately a number of times or even years to become better at certain skills.Daniel Coyle explains in his book, The Little Book of Talent:“...closing the book and writing a summary, even short ones, forces you to figure out the key points, process and organize those ideas so they make sense, andwrite them on the page. When you pick it back up weeks later, reread all of your notes or highlights to strengthen the ideas even further.”People learn by repeating things. Better learning is a repetition process. Every time we repetitively access something we already know, we increase the memory’s stored value.8. Which of the following can be inferred from the passage?A. The brain tends to store 90% of the things we learn.B. The fresher the information isthe easier to remember.C. Thinking is more important than remembering in study.D. The brain tends to choose and keep what it thinks important.9. How does the writer prove his opinion?A.By giving examples.B. By listing numbers.C. By borrowing words of experts.D. By providing scientific finding.10. What does Daniel Coyle want to say in his book?A. You can’t pay too much attention to repetition.B. Summarizing is a very effective learning tool.C. Forgetting forces human brain to make choices.D. Regular repetition helps to form good habits.11. Which do you think is the best title of the passage?A. How the Brain WorksB. Reading for MoreC. Fighting Against ForgettingD. Repeat to RememberDA teenager in Georgia will no longer have to walk 7 miles to work after school thanks to one woman’s act of kindness.Jayden Sutton, a high school senior, went on foot each day from school to his job at a restaurant and then back home. Sutton was determined to work and make enough money to eventually buy his own vehicle.Sutton said he’d leave school at 3:30 pm, then walk miles to his job at the restaurant. After his work, which usually lasted six to eight hours, he walked home, sometimes not arriving back until almost midnight.That all changed when Myers saw him walking down the road in the rain in December. “The young man was insistently in a rush walking to work, saying ‘I can’t be late,’” Myers said. “He begged me to give him a ride. I told him I could take him as far as I was going. I began to create small talk along the way. It wasrevealedto me that hisname was Jayden, 12th grader, worked 40 hours a week, walked 5 miles to work immediately after school, got off at 10:30 pm at night and walked back home another 5 miles if co-workers didn’t offer a ride.”After dropping Sutton off, Myers said his heart and determination filled her with tears. “He was smiling in good spirits and that’s a child worth blessing,” she told Fox News. So, Myers shared Sutton’s story on the GoFundMe page, which raised more than $ 9, 000 from 186 donors.She surprised Sutton with a new car after she managed to convince the general manager to drop the price of the vehicle to meet the budget.12. Why did Sutton work so hard in his spare time?A. To gain working experience.B. To pay for his education.C. To own a car.D. To support his family.13. What difficulty did Sutton have in his work at the restaurant?A. He worked longer than other workers.B. His work was too tiring.C. His job was much less paid.D. He had to walk to work.14. What does the underlined word “revealed” in paragraph 4 mean?A. Known.B. Attached.C. Believed.D. Limited.15. What do we know about the money donated online?A. It could buy more than a new car.B. It was not enough to buy a new car.C. It was given to Myers to buy herself a new car.D It mainly came from a car sales manager.第二节(共5小题;每小题2分,满分10分)阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。
2019-2020学年上海市复旦高级中学高三英语期中试卷及答案
2019-2020学年上海市复旦高级中学高三英语期中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AIf you truly want to live, you need to get out and see the world. Traveling and living different adventures may become your favorite lifestyle. Here is a brief introduction about the top three destinations to visit in the world. ParisFirst on the list is Paris, France. For some people, this shouldn’t be a surprise. For others, they might consider Paris overrated as it has a reputation for being dirty. Any major city in the world might be thought to be dirty by anyone not living in a city. It comes with the territory. The reason Paris is at the top of this list is not because of its famous attractions but because of its charm. You can spend the day walking around cobblestone streets and enjoy elegant cafes and high-end shopping. When you finish satisfying your appetite, you can relax on the banks of the Seine River.Glacier National ParkGlacier National Park comes in second on the list. It is located in Montana, America. It will be well worth the effort thanks to snow-capped mountains, crystal blue lakes, seventy miles of hiking trails, and thirteen camping areas. If you visit during the summer, you can go swimming or white-water rafting. If you visit during the winter, you can go skiing or snowshoeing. But the real allure (诱惑力) and what you will always remember is the breathtaking scenery and fresh mountain air.Bora BoraThe reason Bora Bora is the third on this list is that it’s expensive, which could limit your other travel plans. If you do make it to this small island paradise, you will find peaceful beaches, jungles, luxury accommodations, turquoise water, and some of the friendliest people you have ever met.Other vacation destinations that should be on your list if you’re living the adventurous lifestyle include London, the South Island of New Zealand, Maui, Tahiti, Tokyo, Barcelona and New York City.1. Tourists can ______ to appreciate the charm of Paris.A. enjoy crystal blue lakesB. visit its famous attractionsC. take a walk around cobblestone streetsD. meet the friendliest people you have ever met2. Which of the following points in Glacier National Park will really attract tourists?A. peaceful beaches.B. White-water rafting.C. Snow-capped mountains.D. Fresh mountain air.3. What’s the purpose of this passage?A. to introduce the top three destinations.B. to compare the top three destinations.C. to encourage people to live an adventurous lifestyle.D. to analyze the good and bad points of the three destinationsBSummer heat can be dangerous, and heat leads to tragedy far toooften. According to kidsandcars, org, an average of 37 young children per year die of car heat in the US, when they are accidentally left in a hot vehicle.For Bishop Curry, a fifth grader from Mckinney, Texas, one such incident hit close to home. A six-month-old baby from his neighborhood died after hours in a hot car. After hearing about her death, Curry decided that something needed to be done. Young Curry, who turned 11 this year, has always had a knack for inventing things, and he drew up a sketch (草图) of a device he called “Oasis.”The device would attach to carseats and watch the temperature inside the car. If it reached a certain temperature in the car, and the device sensed a child in the carseat, it would begin to circulate cool air. Curry alsodesigns the device using GPS and Wi-Fi technology, which would alarm the child’s parents and, if there was no response from them, the police.Curry’s father believes that the invention has potential. “The cool thing about Bishop’s thinking is none of this technology is new,” he said. “We feel like the way he’s thinking and combining all these technologies will get to production faster.” His father even introduced the device to Toyota, where he works as an engineer. The company was so impressed that they sent Curry and his father to a car safety conference in Michigan.In January, Curry’s father launched a campaign for the invention. They hope to raise money to finalize the patent, build models, and find a manufacturer. Their goal was $20,000, but so many people believed in Oasis’ potential that they have raised more than twice that — over $46,000.Curry’s father remembers the first time he saw his son’s sketch. “I was so proud of him for thinking of asolution,” he said. “We always just complain about things and rarely offer solutions.”4. What inspired Curry to invent Oasis?A. His narrow escape from death after being locked in a car.B. His knowledge of many children’s death because of car heat.C. The death of his neighbor’s baby after being left in a hot car.D. The injury of 37 children in his school in a car accident.5. What would Oasis do if it was hot in a car with a child?A. It would inform the parents or even the police.B. It would pump out the hot air in the car.C. It would sound the alarm attached to the car.D. It would get the window open to save the child.6. What does Curry’s father think is cool about Curry’s invention?A. It used some of the most advanced technology.B. It simply combined technologies that existed.C. It could accelerate production of new technology.D. It is the most advanced among similar products.7. Why did Curry’s father start a campaign to raise money?A. To conduct experiments to test the invention.B. To get other children devoted to inventions.C. To support a charity of medical aid for children.D. To get the patent and bring it to production.CAs an eco-minimalist, Su Yige has maintained an environmentally friendly and sustainable lifestyle for the past three years while studying in Canada. She takes her own bag when she goes grocery shopping and uses second-hand items as often as possible. She avoids almost all paper-related products unless she has to use a public toilet while away from home.Diligence and thrift are time-honored traditional Chinese virtues. Su's family is a good example of this, according to the native of Weihai, Shandong province. Although they have little formal “green” knowledge, her parents lead a very environmentally friendly life.For example, the family has used the same hair dryer for more than a decade, and Su remembers many ofher mother's clothes from as far back as kindergarten. “As long as something can still be used, my mother will not replace it with a new item,” she said.“I frequently asked my father to bring the plastic bag back home after dumping our waste in the trash bin. He was unhappy, and argued that instead of making that request, I should go downstairs to dump the waste myself” she said. In another move, her father criticized her for doing too much shopping online. Eventually, they both made steps toward becoming better environmentalists. Her father brings the bag back for reuse and she has only bought two pieces of clothing online in the past six months.Back in Canada, Su is looking forward to finding a job related to sustainable development in China after she graduates as a computer science major in the summer.8. Which of the following best describes Su Yige?A. Conservative.B. Nostalgic.C. Economical.D. Productive.9. What can be found about Su's mother according to the third paragraph?A. She has a lot of formal green knowledge.B. She regards using the same items as a lifestyle.C. She always wears old clothes due to lack of money.D. She will not replace the old items until they are out of style.10. What can be inferred about Su and her father?A. Both of them like to criticize each other.B. Su's father is particular about her clothes.C. The relationship between them is very tense.D. They urge each other to become more environmentally friendly.11. What can we learn about the author soon after she graduates in Canada?A. She will stay there to look for a job.B. She will put effort into computer science.C. She will devote herself to her motherland's future.D. She will come back to China to stay with her parents.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 theGold 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 were brought 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. According to the text, which of the following is spoken only by Australians?A. Mate.B. Outback.C. Program.D. Rugby.14. Which is the following can best describe Australian English?A. Confusing and interesting.B. Multicultural and creative.C. Crazy and boring.D. Unchangeable and mixed.15. What might be the best title for the text?A. The History of AustraliaB. The Birth of Australian EnglishC. The Development of Australian EnglishD Different Kinds of English Across the World第二节(共5小题;每小题2分,满分10分)阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。

2019-2020学年上海市复旦高级中学高三英语期中试卷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ARome can be pricey for travelers, which is why many choose to stay in a hostel (旅社). The hostels in Rome offer a bed in a dorm room for around $25 anight, and for that, you’ll often get to stay in a central location (位置) with security and comfort.Yellow HostelIf I had to make just one recommendation for where to stay in Rome, it would be Yellow Hostel. It’s one of the best-rated hostels in the city, and for good reason. It’s affordable, and it’s got a fun atmosphere without being too noisy. As an added bonus, it’s close to the main train station.Hostel Alessandro PalaceIf you love social hostels, this is the best hostel for you in Rome. Hostel Alessandro Palace is fun. Staff members hold plenty of bar events for guests like free shots, bar crawls and karaoke. There’s also an area on the rooftop for hanging out with other travelers during the summer.Youth Station HostelIf you’re looking for cleanliness and a modern hostel, look no further than Youth Station. It offers beautiful furnishings and beds. There are plenty of other benefits, too; it doesn’t charge city tax; it has both air conditioning and a heater for the rooms; it also has free Wi-Fi in every room.Hotel and Hostel Des ArtistesHotel and Hostel Des Artistes is located just a 10-minute walk from the central city station and it’s close to all of the city’s main attractions. The staff is friendly and helpful, providing you with a map of the city when you arrive, and offering advice if you require some. However, you need to pay 2 euros a day for Wi-Fi.1.What is probably the major concern of travelers who choose to stay in a hostel?fort.B.Security.C.Price.D.Location.2.Which hotel best suits people who enjoy an active social life?A.Yellow Hostel.B.Hostel Alessandro Palace.C.Youth Station Hostel.D.Hotel and Hostel Des Artistes.3.What is the disadvantage of Hotel and Hostel Des Artistes?A.It gets noisy at night.B.Its staff is too talkative.C.It charges for Wi-Fi.D.It’s inconveniently located.BNarasimha Das is on his way to feed 169,379 hungry children. Das is in charge of a kitchen in Vrindaban. The town is about a three-hour drive fromIndia’s capital,New Delhi. Das gets to work at 3:00 a.m. Thirty workers are already working to make tens of thousands of rounds of bread. It will be brought to 1,516 schools in and around Vrindaban.A Growing ProblemGoing to school is difficult for more than 13 million children inIndia. They must go to work instead, or go hungry. That’s whyIndiabegan the Mid-Day Meal Scheme, the largest school-lunch program in the world. A free lunch encourages children to come to school and gives them the energy they need for learning. The program began in the 1960s.The kitchen in Vrindaban is run by the Akshaya Patra Foundation. It is one of the lunch program’s biggest partners. “Just $11.50 can feed one child for an entire year,” said Madhu Sridhar, president of the Akshaya Patra Foundation.Lunch Is Served!The Akshaya Patra food truck arrives atGopalgarhPrimary School. Since the program started, the number of underweight children has gone down. The children get foods they need — as long as they finish what’s on their plates.4. What does Narasimha Das do?A. A waiter.B. A salesman.C. A cook.D. A shopkeeper.5. The kitchen in Vrindaban supplies food to ________.A. the poorB. school childrenC. college studentsD. the old6. Why is it difficult for children to go to school inIndia?A. Because they have to work to make money.B. Because there are not enough schools.C. Because there are not enough teachers.D. Because their parents refuse to send them to school.7. Which of the following about the Mid-Day Meal Scheme is NOT true?A. It is to encourage children to go to school.B. It has been carried out for about 50 years.C. It is run by Narasimha Das.D. It is the largest school-lunch program in the world.CUntil quarantine (隔离期) ends, we are left picturing what sport we might do: working out at the gym, playing on a competitive sports team, swimming, biking, or rock climbing. However, we don’t often think of martial arts as possible activities; instead, we rule it out because we think it’s dangerous, uncommon, and even, impossible. Martial arts aren’t considered a sport, right?Well, here’s some good news: you’re wrong! Martial arts aren’t much more common than people think, and you can start learning at any age. Practicing martial arts is a great way to keep in shape, both physically and mentally. They’re much less boring and much lessarduoussport than they’re usually described as in movies, so do not worry that they need a lot of effort.Martial arts generally require you to focus on the position and movement of every one of your legs and arms, sometimes even your breathing too. Think about it: when you leave the gym, your mental state has improved and you are much calmer. This is because you’ve only paid attention to one activity. It is a great way to clear your head. Andpracticing it can help you learn to stay more focused, which is the greatest advantage of martial arts training.Martial arts also improve your coordination (协调性), and greatly improve your posture (姿势). I have personally seen students go from slouching (没精打采) to walking tall with their shoulders back in just a couple of months.There are many styles and countless kinds of martial arts. Whichever one you like better, know that all of them are good choices.8. What can we know about martial arts from the first two paragraphs?A. They often have people hurt.B. They are difficult to practice.C. People have a wrong view on it.D. People practice them more often.9. What does the underlined word “arduous” in paragraph 2 mean?A. Interesting.B. Difficult.C. Friendly.D. Exciting.10. What is the biggest benefit of practicing martial arts?A. Adjusting the breath.B. Enjoying one’s free time.C. Correcting the movement.D. Keeping one’s attention.11. What does the writer think of martial arts?A. They are notsports.B. They attracted many teenagers.C. They are beneficial and helpful.D. They were invented to protect others.DWe all know that a healthy lifemeans getting both plenty of exercise and enough good-quality sleep, but reality often gets in the way. The new research indicates that doing enough exercise could make up for some of the unhealthy impacts of bad sleep. While the health benefits of exercise and sleep are nothing new, it's the relationship between them that is interesting in this particular study — it could even give doctors another option to suggest for patients dealing with sleep problems.“We found those who had both the poorest sleep quality and who exercised the least were most at risk of death from heart disease, stroke, and cancer,” says epidemiologist Bo-Huei Huang, from the University of Sydney in Australia.Participants were grouped into three levels of physical activity (high, medium or low) and were also given a sleep quality score from 0-5 based on the amount of shut-eye they got, how late they stayed up, insomnia, snoring and daytime sleepiness.Those with the highest risk of dying from cancer or heart disease during the study period were those with the worst quality sleep and who didn't meet the WHO recommended guidelines for exercise. That risk went down for people with poor quality sleep but who did meet the exercise guidelines.In the case of all forms of cancer, for example, those at the unhealthiest end of the sleep and exercise scale had a 45 percent higher risk of dying from cancer than those with good sleep scores who kept physically active. However, that risk just about disappeared for those who didn't score well on sleep but did score well on physical activity.For now it's not clear why more exercise might make up for poor sleep, as far as our health goes. It could be that the increased activity iscounteractinginflammation (炎症), or reducing irregularities in glucose metabolism, suggest the researchers.“Considering that physical activity is perhaps more modifiable than sleep, our study offers people more health incentives to be physically active.” says population health researcher Emmanuel Stamatakis, from the University of Sydney.12. This research is of particular interest in that ________.A. it’s in this study that exercise is known to be beneficial to sleep.B. this study offers people more health treatments to be physical active.C. it could enable doctors to cure patients of their sleeping condition.D. the relationship between exercise and sleep is updated in this study.13. Which of the following statements istrueaccording to the passage?A. Those who had the poorest sleep quality were most at risk of death from heart disease.B. Those scoring lowest on sleep and exercise scale were more likely to die from cancer.C. There’s no risk of cancer for those who didn't sleep well but did score well on physical activity.D. It's evident that in terms of health more exercise could make up for poor sleep.14. What does the underlined word in Paragraph 6 mean?A. interactingB. increasingC. preventingD. causing15. Where can this passage most probably be taken from?A. A research findings reportB. A medical examination reportC. A poor sleep study reportD. A physical activity study report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。
