2020年佛山市南海区西樵镇西樵中学高三语文上学期期中考试试题及答案解析

2020年佛山市南海区西樵镇西樵中学高三语文上学期期中考试试题及答案解析一、现代文阅读（36分）(一)现代文阅读I(9分)阅读下面的文字，完成各小题。

“忘言得意”是玄学在认识方法上提出的一个主要观点，也是中国传统哲学的重要思维方式之一。

玄学大家王弼在《老子指略》里说；“夫欲定物之本者，则虽近必自远以证其始。

夫欲明物之所由者，则虽显而必自幽以叙其本。

”这里的“本”“始”即他所谓无形无象、无称无名的“道”。

郭象也同样强调，欲求圣人之道，不应停留在有形之“迹”上，而应当进而把握其“无迹”之“所以迹”。

因此，“忘言得意”的实质，就是认识事物不要停留在迹象上，而要深入内部去把握其根本。

就这方面而言，“忘言得意”反映了人们深化对宇宙、社会认识的要求。

对于“得意”，王弼认为要通过言象获得，而郭象不仅仅讲“寄言以出意”，还更多地强调通过“超言绝象”的“冥合”去获得。

无论哪一种，都强调要充分发挥认识主体的能动作用，而“得意”之深浅，又与认识主体的素质有着密切的关系。

就此而言，这种认识方法包含了由外而内、由内而外、得之于外、证之于内、内外合一、主客通明的过程。

这也正是中国传统哲学思维方法中的一些最重要的特点。

“忘言得意”论不仅在中国传统哲学的思维方式上有着重要的意义，而且对中国传统文学艺术的创作论，尤其是欣赏论也有着巨大的影响。

中国人最注重得意于言外，喜欢那些“意犹未尽”“韵味无穷”的文学艺术作品。

对于只能就眼前呈现的形象来评论文学艺术的人，则认为他根本不够一个真正欣赏者的资格。

苏轼就在一首论画诗中写道：“论画以形似，见与儿童邻。

赋诗必此诗，定非知诗人。

”中国这种传统的欣赏论，给文学艺术欣赏者带来了极大的自由。

同一对象，不同的欣赏者从不同角度、以不同心情去欣赏，往往各有所得。

即使是同一欣赏者，在不同的环境和心情下，对同一欣赏对象也往往有不同的体会。

欣赏者可以充分发挥其主观能动性，以至可以完全离开创作者的原意，体会出另一种新意来。

后来我离开小镇，读书、谋生、飘荡，一晃已是多年。

飘荡和飞翔是完全不同的两件事。

每个人都渴望飞翔，在没有翅膀的时候他们往往选择飘荡，也有很多人在飘荡中找到了飞翔的感觉，甚至慢慢生出了翅膀，但是这种生长过程中的痛楚实在难以忍受，除非你学会了麻木。

当初离开的时候，我想我会回来的。

当初背着行囊离开的时候，我看着车窗外倒退的树木、田野、河流，没想到，故乡从此在我的生命中越来越远。

多年以后，我只能在逢年过节时，偶尔回去。

故乡的风景有的依然熟悉，有的却变得陌生，我在一个个当初毫无新鲜感的地方再次找到了新鲜感，仿佛那些被诗歌擦亮的词语。

在漫漫的时光中，那个我称之为故乡的小镇也开始离我越来越远。

在幽暗的光线里，在朦胧的情景中，在渐渐远去的岁月里，我仿佛只能看到一些模糊不清的人影进进出出那个虚幻般的小镇。

整个小镇仿佛荒草萋萋，迷雾蒙蒙，毫无美感。

虽然在很长一段时间，它是我曾竭力想表达的最珍贵的东西，但现在它像一幕幕消逝的风景一样离我远去。

我也离它远去，做了城市里的居民。

那里没有人为我的到来而感到欢欣，我也不曾有过特别的喜悦。

我在新的地方安然地生活。

毋庸置疑，我的故乡的人们在我离开之后也会依旧幸福快乐地生活着。

不知为什么，我对故乡小镇的深深依恋从来没有改变过。

虽然我离开它已经二十多年了，不过，我还是深深爱着我的故乡小镇，无论是它的过去，还是它的现在，或者是遥远的将来，这种爱是深入骨髓的。

虽然我的少年和成年都没有在那里待多久，但这种与生俱来的爱却让我在以后的日子里时时想起那个古老的地方。

尽管我可以幸福快乐地生活在其他城市里，可是我忘不了故乡小镇所有的人和那里曾经发生过的所有的事。

To collect the ideas for tours.BWhen you walk on a sandy beach, it takes more energy than striding down a sidewalk — because the weight of your body pushes into the sand. Turns out, the same thing is true for vehicles driving on roads. The weight of the vehicles creates a very shallow indentation (凹陷) in the pavement (路面) — and it makes it such that it’s continuously driving up a very shallow hill.Jeremy Gregory, a sustainability scientist at M.I.T. and histeam modeled how much energy could be saved — and green-house gases avoided — by simply stiffening (硬化) the nation’s roads and highways. And they found that stiffening 10 percent of the nation’s roads every year could prevent 440 megatons of carbon dioxide equivalent emissions over the next five decades — enough to offset half a percent of projected transportation sector emissions over that time period. To put those emissions savings into context — that amount is equivalent to how much CO2 you’d spare the planet by keeping a billion barrels of oil in the ground — or by growing seven billion trees — for a decade.The results are in the Transportation Research Record.As for how to stiffen roads? Gregory says you could mix small amounts of synthetic fibers orcarbon nanotubes into paving materials. Or you could pave with cement-based concrete, which is stiffer than asphalt (沥青).This system could also be a way to shave carbon emissions without some of the usual hurdles. Usually, when it comes to reducing emissions in the transportation sector, you’re talking about changing policies related to vehicles and also driver behavior, which involves millions and millions of people — as opposed to changing the way we design and maintain our pavements. That’s just on the order of thousands of people who are working in transportation agencies. And when it comes to retrofitting (翻新) our streets and highways —those agencies arewhere the rubber meets the road.4. Why does the author mention “walk on a sandy beach” in paragraph 1?A. To present a fact.B. To make a contrast.C. To explain a rule.D. To share an experience.5. What suggestion does the author give to reduce CO2 emissions?A. Hardening the road.B. Keeping oil in the ground.C. Growing trees for decades.D. Improving the transportation.6. What is the advantage of this suggestion?A. Gaining more support.B. Consuming less money.C. Involving more people.D. Facing fewer usual obstacles.7. What does the underlined part mean in the last paragraph?A.Those agencies are likely to make more rules.B. Those agencies will change some related policies.C. Those agenciesmight put more rubber tires on the roads.D. Those agencies will play a key role in making this happen.CLast summer, I spent four months working in France, where the company I was working for put me up in a house that didn’t have Wi-Fi. I wasn’t looking forward to it.I soon discovered, however, that living in a house without Wi-Fi was easier than I expected.Contact between my friends and family was significantly reduced to the odd text message here and there. I couldn’t enjoy my usual web browsing on BBC iPlayer, social media sites, keeping up to date with the news, or even wanting to know the opening hours of shops in the new area I was in.I didn’t, however, spend a full four months without connecting to a Wi-Fi network. It was only a five minute walk to the reception where I could connect for free and spend as much time online as I wanted to at my own leisure. It made me think , though , how unnecessary it can be , how unnecessarily we rely on it—how we perhaps rely on it too much. As a person, I was more sociable. I spent more time with my housemates instead of hiding behind a computer screen. I did other things that I wouldn’t necessarily have done if I could have browsed the web at my leisure. I read more, I cooked meals for my friends, and I even tidied up more often. Dare I say it; I learned how to live without Wi-Fi. Dare I say it; I found it was easier than I had imagined.8. What was the writer’s first feeling when finding her house had no Wi-Fi?A. Unexpected.B. Angry.C. Shocked.D. Depressed.9. How did the writer keep in touch with her friends and family without Wi-Fi?A. By writing regularly.B. By text message.C. By video calls.D. By telegram.10. What was the writer’s life like without Wi-Fi?A. Dull.B. Lonely.C. Active.D. Relaxing.11. What can be a suitable title for the text?A. A life without Wi-FiB. Different views on the InternetC. The disadvantages of Wi-FiD. How to use the InternetDAn unmanned Chinese spacecraft left the earth on a trip to the planet Mars on Thursday. The launch（发射）marks the start of one of China's most important space explorations. China's national space agency launched the spacecraft called Tianwen-1 fromthe Wenchang Spacecraft Launch Center on Hainan Island.The name Tianwen means “Questions to Heaven” in Chinese. The spacecraft took off on China's largest carrier rocket, the Long March 5, and about 36 minutes later, the spacecraft, including an orbiter（轨道飞行器）and a rover（漫游车），was sent into the Earth-Mars orbit. It is expected to reach the orbit of the red planet next February. Tianwen-1 will finish three scientific goals—orbiting the red planet, landing on the Mars and sending a rover to the landing site.Tianwen-1 carries several scientific instruments to observe the planet's atmosphere and surface. It will do a series of scientific researches on the planet's soil, geological structure, environment, atmosphere and water. Besides its daily work of exploring the surface of Mars for 90 days, it will also report back to the earth about its experiences on the red planet, which is millions of miles away. According to experts, discovering signs of life will be its first and most important scientific goal.Tianwen-1's successful landing will make China the second nation to place a spacecraft on Mars. The United States has landed eight vehicles on Mars since 1976. China will be the first to successfully orbit, land and place a vehicle in the same mission. This is China's first independent mission to Mars. The task in 2011 failed when a Russian rocket carrying a Chinese orbiter had problems after launch, and was unable to escape the Earth orbit. Last year, China's Chang e-4 spacecraft became the first to make a landing on the far side of the moon.12. When will Tianwen-1 enter the orbit of Mars?A. 36 minutes later.B. Next Thursday.C. In 90 days.D. Next February.13. What is the main task of Tianwen-1 according to experts?A. Orbiting the Mars.B. Landing on the Mars.C. Discovering signs of life.D. Sending a rover to the landing site.14. Which of the following statements is mentioned in the text?A. Tianwen-1 is the second vehicle landed on the Mars.B. The United States is the first to land vehicles on the Mars.C. Russia helped China place Tianwen-1 on the Mars.D. Chang，e-4 was the first to make a landing on the moon.15. Where can you find this article?A. In a newspaper.B. In a diary.C. In a sci-fi novel.D. In a guide book.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。

Trees can lower summer daytime temperatures by as much as 10 degrees Fahrenheit, according to arecent study. But tree cover in US cities is shrinking (缩减). A study published last year by the US Forest Service found that we lost 36 million trees annually from urban and rural communities over a five-year period. “If we continue on this path, cities will become warmer, more polluted and generally unhealthier for inhabitants,” said David Nowak, a senior US Forest Service scientist and co-author of the study. Nowak says there are many reasons why our tree cover is declining, including hurricanes, tornadoes, fires, insects and disease. But the one reason for tree loss that humans can control is sensible development.Nowak says there is a downside to trees too, such as pollen allergy (花粉过敏) or large tailing branches in storms, and people don’t like sweeping leaves. But, he says, there are ways cities and counties can manage trees to help communities thrive (繁荣). Urban forests especially need our help to replace fallen trees. Unlike rural areas, it is very difficult for trees to repopulate themselves in a city environment with so much pavement and asphalt (沥青). “A lot of our native trees can’t actually find a place to drop a seed so they can regenerate,” explains Greg Levine, co-executivedirector of Trees Atlanta. “That’s why the community has to go in and actually plant a tree because the areas just aren’t natural anymore.”Nowak says the first step is caring for the trees on your own property (财产). “We think we pay for our house, and sowe must maintain it. But because we don’t pay for nature, we don’t need to. And that’s not necessarily true.”4. Why does the author mention “trees can lower summer daytime temperatures”?A. To tell the temperatures in summer are high.B. To explain the reason of tree loss.C. To tell trees are helpful.D. To introduce the topic.5. How can humans control tree loss according to Nowak?A. Develop cities in reasonable ways.B. Prevent fires form damaging trees.C. Improve climate to let trees grow.D. Decrease insects in cities.6. Why do forests in cities need our help?A. Because trees don’t grow in a city environment.B. Because native trees don’t drop seeds any more.C. Because trees in urban areas can’t regenerate naturally.D. Because humans want to plant more trees.7. What is the purpose of this passage?A. Describe the importance of trees in cities.B. Appeal people to protect trees in their surroundings.C. Ask people to plant trees with the author.D. Show the number of trees in theUSis declining.CThe cumulative rainfall in Henan province during the four days was the highest since the province has records, the provincial meteorological service said. The rain was heaviest in the provincial capital, Zhengzhou, for a short period on Monday and Tuesday. Northern, western and central parts of Henan also experienced downpours, the service said. Zhengzhou's biggest one-hour precipitation (降水量) —201.9 mmbetween 4 and 5 pm on Tuesday—was also the highest on the Chinese mainland. The previous record was 198.5 mmin the village of Linzhuang in Zhumadian in August 1975, the National Meteorological Center said. The city's precipitationduringthe four days exceeded that of its average annual precipitation, the center said.Chen Tao, chief forecaster at the National Meteorological Center, said abundant water vapor (水蒸气) brought by Typhoon In-Fa and the province's special geographical features led to Henan's rain. “Partly affected by the typhoon, large amounts of water vapor have been transported to China's inland areas, including Henan,” he said.From Thursday to Monday, rain was forecast to continue in Henan. However, rainfall will gradually subside in Zhengzhou and the province's northern and central regions, though the storms will increase the risk of mountain torrents and other geological disasters. By Monday, lighter rain is forecast for parts of Henan, the provincial weather service said. However, local authorities are still urged to bevigilantand prepare to prevent or cope with flooding and other possible disasters.Predicting such weather events remains a challenge worldwide because it involves many meteorological phenomena, the center said. “The formation of this kind of extreme weather, including rainstorms and high temperatures, is complex,” Chen said. “We still lack effective solutions and methods for such forecasting”, he said. “We are now putting a lot of effort into tackling the difficulty. We believe that as the technology improves, we can better forecast the events.”8. What message does the author mainly want to convey in the first paragraph?A. heavy rain fell in Zhengzhou.B. The rain in Henan lasted four days.C. Zhumadian also suffered the similar heavy rain.D. Henan experienced the biggest rainfall of all time.9. What can be indicated from Chen Tao's words?A. It is not easy to forecast the extreme weather.B The rain of Henan is mainly caused by Typhoon In-Fa.C. The center hasn't put a lot of effort into solving the problem.D. Rainstorms and high temperatures can account for the heavy rain.10. What does the underlined word “vigilant” probably mean?A. Relaxed.B. Alert.C. Reluctant.D. Communicative.11. Where might the text be most probably taken from?A. history book.B. A novel.C. A news report.D. A science magazine.DFor fishermen and sailors in the seaside town of Shangpan in Linhai, Zhejiang province, where recently 12 stranded（搁浅的）whales were found, it is not unusual to spot whales or dolphins in the sea — they would always call them haizi, or “son of the ocean”. And if the local fishermen spot such intelligent sea creatures in need, they will save them from danger without hesitation.In the recent rescue of melon-headed whales, they tried their best to help as a 37-second video of a young man sleeping in the water holding a whale soon went viral online, with netizens applauding his constant efforts and caring heart in trying to keep the whale alive. “The melon-headed whale knew I was trying to save it and would be more cooperative and wouldn’t move.” said Lu Wenhui, a 21-year-old diver from Hangzhou Changqiao Polar Ocean Park, who held up the whale’s head so it could breathe easily. Lu had been staying in the water for 10 hours by 4 a.m. Wednesday after coming for the rescue work on Tuesday, when the stranded whales were first spotted.“Whales are mammals and need to breathe in air — that’s why I had to hold its head, to ensure it could breathe smoothly the whole time,” Lu said. The stranded whales, after the struggling of being transported, were worn out when they arrived at the fish farm and might have drowned if they were left unattended.The reason why the whales were stranded is still not clear. And these stranded whales were returned to the ocean because they are not adapted to artificial breeding environments on land.12. What do local fishermen usually do after finding haizi in danger?A. Ignore them.B. Feed them.C. Transport them.D. Protect them.13. Why does the author describe Lu’s rescue work?A. To introduce the whales in detail.B. To voice his views on the diver.C. To praise the efforts made by rescuers.D. To explain the value of the whales.14. What can we say about the melon-headed whales according to the text?A. They are rarely seen by locals.B. They are used to breathing in the sea.C. They aren’t suited to artificial surroundings.D. They are fond of swimming near the seaside.15. Which of the following can be the best title for the text?A. Melon-headed Whales Were StrandedB. Rescuers Went All out to Help WhalesC. Fishermen Transported Stranded WhalesD. Witnesses Voiced Opinions on Rescue Work第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

2020年佛山市南海区西樵中学高三语文下学期期中考试试题及答案解析

2020年佛山市南海区西樵中学高三语文下学期期中考试试题及答案解析一、现代文阅读（36分）(一)现代文阅读I(9分)散文阅读（18分）木车的激情张炜在现代旅行中，我们常常因为交通工具的不够迅捷而焦躁和苦恼。

我们祈盼乘坐的车辆眨眼间就到达目的地，幻想它能像闪电一样穿越莽野。

我们有时甚至为最现代的旅行交通工具——飞机——感到焦急，比如说为机场的长长滞留、耽搁，感到愠怒和不安。

我们总是那么急于从甲地到乙地，总是有那么多事情要做。

我们碌碌奔波，但催促我们行动的激情是那样脆弱和渺小。

我们怎么能够想象几千年前，有一位思想者就乘坐着一辆缓慢的牛车或马车，在大地上往复奔走，是的，他为了自己的思想，为了自己的理念而不知疲倦，并这样终其一生。

他就是我们所熟悉的古代哲人孔子，还有他的一群弟子。

他们都是一些为思想而激动的不知疲倦者。

我们不妨把这些人的一生、把这一切，称为“木车的激情”。

由于车速是极其缓慢的，里程是极其艰难的，因而我们今天更有理由说，他的激情才更为强大、更值得信赖。

枯叶铺地，北风呼啸。

在冬天，那个哲人也不能舍弃自己的旅程。

这在越来越聪明的现代人眼里是不可思议不可理解的。

一位不可理喻的执著者，让世界感到畏惧了。

“政治”这两个字在现代或许已经变质。

我们现代人几乎仅仅可以从那辘辘的木车声中，听到“政治”的真正含义，领略它的本质。

它那时候是人、旅途、木车，是面对土地的求索，是这样的不知疲倦。

原来在古代，“政治”和“诗”是合二为一的，这才让后人生出了永久的崇敬。

他不倦地向各个阶层诉说他的思考，他的思想，他对这个世界的观察，他探索到的各种各样的原理。

作为一位布道者，一位启蒙者，一位诗人，大概这个世界上没有几个人能够与他比肩。

但人们往往承认他是布道和启蒙者，而不愿承认他是诗人。

可是，现代人在这个寒冷的冬天，在北风击碎冰凌的时刻，真的不能从辘辘的马车声中，听到和看到孔子那一腔燃烧的诗情吗？这是一首长长的、写在大地上的诗，是可以从东方播散到西方的长卷。

2020年佛山市南海区西樵镇西樵中学高三英语期中考试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AEach year, theLas Vegasconsumer electronics show, or CES, presents the latest developments in many areas of technology. The newest products are designed to make our lives easier, fun and more productive.A car with legsOne of this year’s presentations was by South Korean carmaker Hyun-dai. The company introduced a small model of a “ walking car,” which is called Elevate. It has four movable legs that can raise the main part of the vehicle high off the ground. The electric-powered vehicle is designed to be used in search-and-rescue operations during emergencies or natural disasters.Changeable people moverGermany's Mercedes presented an experimental self-driving vehicle that it claims can revolutionize transportation for people and goods. The company says the vehicle, called Vision Urbanetic, will be able lo easily change bodies depending on its desired use. Mercedes says as a ride-sharing vehicle , the futuristic-looking car can seat 12 people.Fully electric HarleyAmerican manufacturer Harley-Davidson showed off its first fully electric motorcycle, called LiveWire. The company says the bike will be able to go 177 kilometers between charges. It can reach 96 kilometers per hour in under3.5 seconds. Although Harley is known for building powerful bikes with huge, loud motors, the LiveWire will be unusually quiet.Personal robotsOne of the new robots, called Temi, is really just a computer tablet on wheels. It is designed to be a personal electronic assistant. It moves around the home and performs commands when spoken to. It can link users to friends through voice or video, connect to video or place orders for food or goods.1. Which do you probably use to search for the injured in an earthquake?A. Elevate.B. Vision Urbanetic.C. LiveWire.D. Temi.2. What is the first fully electric motorcycle produced by Harley-Davidson?A. ElevateB. Hyun-daiC. LiveWire .D. Temi .3. Why are the four products designed?A. To ease traffic jam.B. To help us socialize.C. To improve our life.D. To protect the environment.BBecause of COVID-19, in many places, large gatherings of people aren’t allowed. In some areas, the rules are more strict, and people aren't allowed to leave their homes unless going out is ly necessary.These steps are very important for slowing the disease down. By doing this, governments can make sure doctors and hospitals are better able to deal with all the sick people, and that fewer people suffer in all. Usually, it's called “flattening the curve”.But if no one can go out, that means businesses which depend on visitors struggle. Many singers, bands, and other musicians would normally be giving concerts now. Instead, they have to find new ways to share their music and connect with their audiences. The Metropolitan Opera in New York has canceled(取消) its season, but it is showing a special live stream of a different opera each day on its website. Other opera companies have made similar moves. Several theater companies are either offering recorded versions of their plays online or posting videos of their actors performing.Nick Green wrote a musical play that was canceled because of the virus. He set up a website with links that allow people to enjoy the work of artists around the world who have had their projects canceled. He called his project the Social Distancing Festival. He sad it was a time when he should be doing something new, rather than feeling disappointed.Even TV shows have to find new ways to film their shows. Some late night TV shows have continued, but without audiences. Others are showing reruns.While their shows are on pause, some TV stars like Conan O’Brien and Jimmy Fallon have been filming short videos at home. Mr. O’ Brien plans to bring his show back on the air soon by filming with his own phone and talking with guests over the Internet.4. What does the underlined phrase in Paragraph 2 refer to?A. Keeping patients staying at home anytime.B. Speed up the spread of disease.C. Stopping people from often gathering up.D. Slowing down the spread of the disease.5. What are opera companies’ new ways?A. Stopping sharing music with audience.B. Providing live stream services.C. Trying to attract live audiences.D. Sharing their operas with each other6. What did the cancellation of Nick Green's play bring him?A. Disappointment.B. Annoyance .C. Creativity.D. Anxiety.7. What is the text mainly about?A. People staying at home .B. The absence of audiences.C. The efforts of Nick Green .D. Entertainment going online .COne of the most popular street food found inChinais no doubt the barbecue. A new program, called Chinese Barbecue, tells the story of this popular food cooked over hot coals on just about every street corner in cities and towns across the country. Barbecued meat is an important part of people’s nightlife.Shown on June 20, the program has had more than 25 million clicks on the video site . To find the most popular barbecue stalls (摊位), the production team travelled to more than 500 locations in 30 cities across the country. Some viewers compare Chinese Barbecue to Midnight Diner, a Japanese TV program telling stories from late night informal Japanese bars.“I’m happy to hear this comparison because Midnight Diner is a good program, and we share the same topic― night food,” Chinese Barbecue’s director Chen Yingjie said. “However, they are quite different.” He said that Midnight Diner focused more on food itself, though there was someconversation while people were eating. However, the night food scene of Chinese people means joy and a more lively atmosphere. People eating these barbecue snacks develop a feeling of connection, which can be a cure for loneliness.The barbecue, regarded as the most ordinary and common night street snack, is different from home-made food by mothers as that is a symbol of family and kinship. The barbecue is where you go to become connected to people in society. And unlike official business lunches, during which people are rather polite, the barbecue lets people relax with old friends and new friends, leaving a lasting impression of friendship.The world, as a whole, holds deep-rooted good feelings toward the barbecue, either for the taste or the warmth produced by fire. “What we should do is to present the Chinese barbecue just the way it is because with its special ingredients(食材)，ways of cooking and more importantly, the special environment and people, the world will recognize it and might fall in love with it just as we do.” said Chen.8. What do we know about Chinese Barbecue?A. It has been becoming very popular on the Internet.B. It is thought highly of by most of the foreign tourists.C. It mainly talks about the most famous Chinese food.D. It shows the color1 ful nightlife in large cities ofChina.9. In which way was Chinese Barbecue different from Midnight Diner?A. It showed more kinds of food.B. It focused more on the diners.C. It showed the eating habits.D. It was less popular than Midnight Diner.10. What is Paragraph 4 mainly about?A. The importance of the barbecue to family.B. The influence of the barbecue on people’s manners.C. The influence of the barbecue on people’s lifestyle.D. The role of the barbecue in people’s relationship.11. Why did Chen Yingjie choose the barbecue as the topic of the series?A. To show the feature of Chinese food.B. To research a special way of cooking.C. To help the world understandChina.D. To introduce the history of the barbecue.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 Institute College 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 sculpturesthat 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. Which of the following is a suitable title for the text?A. A stylish, stubborn old manB. Sculptures towering into the cloudsC. JohnD. Ferguson—a famous sculpturer D. The evolution of the sculptural style第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

2020-2021学年佛山市南海区西樵镇西樵中学高三英语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AA brother and a sister have been reunited (重逢) after more than 60 years, thanks to a letter in the Welwynand Hatfield Times. For years John Hannant kept a photo of his long-lost sister, hoping they would meet again.Margery, the eldest of three children, had signed up with the Royal Air Force as part of the war effort, when John was still a baby.The family lost touch and as many years passed only a single letter gave a clue to her whereabouts (下落). The clue was enough for a WHT reader to recognize Margery and put the family back in touch.John, 67, said he had been searching for a long time and a friend suggested writing to the paper.“That’s the one that made it, the letter to the paper,” he said. “It’s like a dream that comes true. The last time we ever heard from Margery was in 1953 after the terrible floods. She wrote home to know if we were all right.My sister Dorothy wrote back, but Margery had moved again and never got the letter.”Having retired from his job as a gardener at Park House, Mr Hannant decided to take action.He and his wife Doreen traveled to Margery’s home in Chelwood Avenue, Hatfield, which she shares with her husband Jack Cooke.Now 88, Margery was recovering from her heart operation, but immediately recognized her brother. John said, “It’s something I never thought that was going to happen but I always hoped it would.” AS well as finding his sister, John has also discovered he now has a nephew, a niece and six grandnieces and grandnephews.1.The headline of the news would be “________”.A.An unforgettable and moving experienceB.The Hannant family lost touch because of warC.A brother and a sister reunited after 60 yearsD.The importance of a letter to WHT2.Margery left her family because ________.A.she attended the air schoolB.she joined the Royal Air ForceC.she had to feed her familyD.a big flood hit her hometown3.Who helped the family reunite after many years?A.Margery’s husband Jack CookeB.The photographer of the photo of Margery.C.A neighbour of Mr Hannant.D.A reader of WHT.BThree years ago, a group of researchers at Cornell University Food and Brand Lab had a guess. They knew that many apples being served to kids as part of the National School Lunch Program were ending up in the trash, almost untouched. But unlike others, they wondered if the reason was more complicated than simply that the kids didn’t want the fruit.They thought the fact that the apples were being whole, rather than sliced (切片的), was doing the fruit no favor. And they wanted to prove this idea.They carried out a study at eight schools and found that fruit consumption (消费) jumped by more than 60 percent when apples were served sliced. They then made a follow-up study at six other schools, which not only showed the same result, but further supported. The whole apple consumption at schools that served sliced apples reduced by about 50 percent than before.Based on these results, it seems that even the simplest forms of inconvenience can influence us. Sliced apples just make more sense for kids. The hardest part is getting kids to start eating fruit, and that’s exactly why sliced apples are the way to go. A child holding a whole apple has to break the skin, eat around the core (果核), and deal with the inconvenience of holding a large fruit. These problems might seem silly or unimportant, but they’re important when you’re missing teeth or have braces (牙箍), as so many kids do.Sometimes what seems like a really small inconvenience actually makes a huge difference.4. What can we learn from Paragraph 1?A. Lots of apples served to kids were wasted.B. Researcher supported the lunch program.C. Apples are not the only acceptable fruit for kids.D. The lunch program was well worth spreading.5. What did researchers want to prove?A. Kid didn’t want the fruits.B. Kids favored the whole apples.C. Kids preferred to the sliced apples.D. Kid’s eating habits influenced fruit consumption.6. According to the study, we can know________.A. 14 schools served sliced fruitsB. kids have problems eating the whole applesC. eating fruits must be healthy for childrenD. few kids are missing teeth or have braces7. What’s the main idea of the passage?A. Form matters more than taste.B. Apples are beneficial to each kid.C. The way fruit is eaten links kids’ growth.D. Inconvenience probably makes a difference.CNewspapers in Great Britainvarygreatly in their ways of carrying the news. There are serious papers for those who want to know about important happenings everywhere, both at home and abroad. There are popular newspapers for those who prefer entertainment to information.The London newspaper that is best known outside Great Britain is probably the Times. It began in 1785, and has a high reputation for believable news and serious opinions on the news. It calls itself an independent paper, which means that it does not give its support to a particular political party.

However, some scientists believe it should be considered a praise, given that many birds can perform human tasks like producing and using tools, solving problems, and planning for future needs. Now,Griffin, an African Grey parrot, has proved that birds may even possess better visual memories than human adults and children.The study, led by Hrag Pailian, a researcher at Harvard University, had the parrot compete in the game against twenty-one undergraduate students and twenty-one 6 to 8-year-old children. The popular challenge involves hiding a small object under one of three or more upside-down cups, which are moved around. Participants are required to accurately identify the cup under which the object lies. To make the task more challenging, the researchers required participants to track two, three, and four objects at the same time.An analysis of the results showed thatGriffinoutperformed the 6 to 8-year-olds across all levels on average. Even more impressive, the "bird brain" performed as well as, or slightly better than, the 21 Harvard students on 12 of the 14 trials! It was only in the final two tests, which had the most objects and most movement, that the parrot fell behind the adults. However,Griffin's performance was never below that of the children.Griffinwas the candidate of choice because the scientists needed an animal that had a brain functionality similar to that of humans. "The fact that the smart parrot loves to show off his brain power in exchange for a few cashews (腰果) did not hurt either", said Irene Pepperberg, a Harvard lecturer, who has trained Griffin and several other African Grey parrots, has been studying the species for over four decades and is considered a pioneer in the study of bird intelligence.12. Whatwere the participants required to do in the study?A. Identify different kinds of objects.B. Tell where the hidden object lies.C. Track other participants' performance.D. Move around upside-down cups.13. What did the results of the study indicate?A. 6 to 8-year-olds did better thanGriffin.B. Parrots have a better memory than other birds.C. Harvard students have a better visual memory.D.Griffinoutsmarted Harvard students in some trials.14. Why wasGriffinchosen for the experiment?A. It was good at making decisions.B. It was specially trained for experiments.C. It had similar brain functions to human beings.D. It loved to show off his language power for some treats.15. What is the best title for the text?A. "Bird brain" becomes a term for a stupid person.B. Harvard lecturer pioneers in bird intelligence study.C. Parrot outsmarted Harvard students in visual memory test.D. Researchers made new discoveries about human intelligence.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 oil and gas industry has forcefully used the technique known as hydraulic fracturing (水力压裂法) to destroy sub-surface rock and liberate the oil and gas hiding there. But the process results in large amounts of chemical-filled waste water. Horizontal drilling (水平钻孔) for oil can also produce large amount of natural, unwanted salt water. The industry deals with this waste water by pumping it into deep wells.On Monday, the US Geological Survey published for the first time an earthquake disaster map covering both natural and “induced” quakes. The map and a report show that parts of the central United States now face a ground-shaking disaster equal to the famously unstable terrain (不稳定地形) of California.Some 7 million people live in places easily attacked by these man-made quakes, the USGS said The list of places at highest risk of man-made earthquakes includes Oklahoma, Kansas, Texas, Arkansas, Colorado, New Mexico, Ohio and Alabama. Most of these earthquakes are ly small, in the range of magnitude (震级) 3, but some have been more powerful, including a magnitude 5.6 earthquake in 2011 in Oklahoma that was connected to waste water filling.Scientists said they do not know ifthere is an upper limit on the magnitude of man-made earthquakes; this is an area of active research Oklahoma has had prehistoric earthquakes as powerful as magnitude 7.It's not immediately clear whether this new research will change industry practices, or even whether it will surprise anyone in the areas of newly supposed danger. In Oklahoma, for example, the natural rate of earthquakes is only one or two a year, but there have been hundreds since hydraulic fracturing and horizontal drilling, with the waste water filling, became common in the last ten years.4. What kind of human activities can cause earthquakes?A. The man-made produced waste water in the factories.B. The process of digging deep wells in those poor areas.C. The advanced techniques used to deal with waste water.D. The oil or gas industry's work connected with the earth.5. What does the underlined word “induced” in paragraph 2 mean?A. Man-made.B. Reduced.C. Newly-built.D. Controlled.6. How much magnitude can man-made earthquakes reach?A. It's been said as small as magnitude 3.B. It has been said as high as magnitude 7.C. It's being studied without a final conclusion.D. It has risen by an average of magnitude 5. 6.7. What is the best title for the text?A. Natural Earthquakes in America Are Disappearing NowB. 7 Million Americans at Risk of Man-Made EarthquakesC. Time for Oil and Gas Industry Change Their Working PracticeD. More Often Earthquakes as Powerful as Magnitude 7 in AmericaCWe interviewed two people, one who went from the country to the city and one who did the opposite.Janet Lincoln is a salesgirl who moved to St. Louisfive years ago. Here’s what Janet told us:“Five years ago I used to live in a small town called Lemon Falls. I grew up and went to high school there. After I graduated I worked in a supermarket. Lemon Falls had a population of about 800 people, and I knew every single one of them. They all knew everything about me, too. You couldn’t do anything without everyone in town knowing about it. The first chance I got I moved to St. Louis and I love it. I don’t know as many people now as I used to, but that’s OK. I have a few good friends, and I see them when I want to. I kind of like beinganonymous. I’d never go back to Lemon Falls.”Troy Henson had the opposite experience. He and his wife, Darla, and their two children moved from St. Louis to Bloomfield three years ago. Here’s what Troy told us:“The best thing we ever did was get out of St. Louis. Don’t get me wrong; St. Louis is as good a place as any other city, I suppose — if you like cities, that is. We don’t. Both Darla and I grew up in St. Louis. We met at college and got married. Then the kids came along and life got difficult. We didn’t know any of our neighbors. We both had good jobs, but it always seemed like there was never enough money. That all changed when we moved to Bloomfield. I don’t make as much money as I used to, but then we don’t have as many expenses as we did. We know our neighbors. Life is good. We’d never leave Bloomfield.”8. What troubled Janet when she was in Lemon Falls?A. She had no friends.B. There was no privacy.C. There was a lot of competition.D. She couldn’t find a well-paid job.9. What does the underlined word “anonymous” in Paragraph 3 mean?A. Alone.B. Prepared.C. Sociable.D. Unknown.10. Different from Janet, Troy ________.A. prefers country lifeB. moved to a bigger cityC. grew up in a smaller townD. knows little about his new neighbors11. What is Troy’s opinion on living in Bloomfield?A. It is a little boring.B. It is quite comfortable.C. It costs a lot of money.D. It creates a safe environment.DBack about 20 months ago I started college and just struggled with everything, such as classes and friends. I quickly became depressed and angry at myself for not being about to do better in school, in addition to lack of friends due to poor social and communication skills.This went on for months until my 19th birthday. My parents sent me a cake, which was a great cake. But I remember having this large cake and ly no one to share it with. I ended throwing out the cake after having one piece, with about 90 % of it leftover. That night I was depressed that I decided to go outside to the freezing temperature of the winter and run. I put my earphones in, went outside and ran about 2 miles at 11 p.m. on my birthday.When I got back inside I was content. I was proud of what I was able to do. The next night I did the same. I wasn’t quick or fit but you know that I went outside and did something. This continued for about 2 months until I finally worked up the courage to go to the gym, where I started swimming again as I used to in high school. A month went by and I started lifting weights and continually running.Looking back I can see that exercise helped cure my depression but it didn’t only do that. At the gym I met new friends and back at my dorm I grew confidence to go to the end of the hall seeing people playing Super Smash Brothers and ask if I could join.So go forward to present now. I exercise every day and look forward to that hour and a half I get daily to do what I love with people who love it as well. I hope this helps someone who may be or have been in a similar situation.12. What made the author decide to run at night?A. His l9th birthday.B. His parents’ cake.C. His loneliness.D. His friends.13.
