And the noisy situation and endless housework may result in a terrible emotion. A new option is waiting foryou. That is WFH: work from a hotel.Hotel FigueroA special program titled Work Perks aims to reposition some of 94-year-old Hotel Figuero’s 268 rooms as day-use offices.According to Managing Director Connie Wang, the set-up launched in June and is a great opportunity to get out of their houses with high-speed Wi-Fi, unlimited printing privileges and free parking.

Well, they do, and you can lean to understand “horse talk” if you pay close attention to the horses you see.When horses live in the wild, other animals try to eat them, so a lot of horse talk is about staying alive. Even now, when most horses live on farms, they watch for danger. For this reason, never walk behind a horse. If you surprise it, the horse might mistake you for a mountain lion or wolf and give a dangerous kick.By watching the ears of a horse, you can get clues to what it's hearing. A horse can tum each ear in a different direction. For a wild horse, this trick is important for survival. The horse can hear something sneaking up behind it while also checking out a threatening noise in front. When a horse lets its ears down, it's feeling safe and relaxed. If horses becomeisolated, they neigh, or “whinny,” calling for company. They're saying, “Where are you? I'm over here!” If a horse snorts(哼) while holding its head high and staring at something, it's saying, “That looks dangerous. Get ready to run!” When two horses meet, they put their noses together and smell each other's breath. It's their way of asking, “Are you a friend?” Horses nicker,too. Nickering is a quiet sort of sound. This friendly noise means they're feeling secure and saying, “Clad to see you.”In the wild, horses live in herds, with all members watching for danger. In a herd, only one horse is the leader, the “boss hoss”. The “boss hoss” is usually an older female. She watches for threats and teaches younger horses how to behave. However, others may want her job. When that happens, she pins her ears back against her head and may even bite or kick to get challengers to back off. She's using body language to say, “Hey, I'm in charge here!” All horses know that the one who makes others move is the leader. Horses relate to people that way, too.Horses have a language of their own. Now you know a bit of what they might be saying.4. What is the general idea of this passage?A. Horses can talk with their owners.B. You can know a bit of horses' language.C. Horses can “talk” in their own way.D. Other animals can also learn language.5. What does the underlined word “isolated” in Paragraph 3 mean?A. Lonely.B. Glad.C. Sad.D. Frightened.6. What will a horse do when he wants to know whether another horse is a friend?A. He will let his ears down.B. He and another horse will put their noses together and smell each other's breath.C They both will hold their heads high and stare at something.D. He will give another horse a dangerous kick.7. How will the “boss hoss” deal with her challengers?A. By warning or fighting.B. By watching for threats.C. By teaching younger horses how to behave.D. By relating to people.CYu Chenrui, 29, is a maker of automata (机关人偶) in Chengdu, Sichuan province. Automata are built to look like humans or animals and give the illusion (错觉) of being able to move ontheir own, “The art form amazes me, because it combines various skills, from storytelling to mechanics, and the pieces are built with a sense of humor,” Yu says. His creations have caught the attention of well-known artists and his fancy pieces of art have attracted collectors worldwide.Interested in handcrafts as a boy, Yu first encountered automata designed by Japanese artist Kazuaki at an exhibition in 2015 when he studied at the Communication University of China in Beijing. “It was like meeting a like-minded friend, ” Yu says, recalling the moment. As an art and design major, he began to learn the craft by himself and, with the support of his tutor, he kept studying and examining automata in school.When he graduated in 2016, Yu landed a job at an advertising agency in Beijing. He stayed on at the company for three years because, at that time, he was not sure that he could make a living out of his hobby. While working as a designer Yu kept exploring and advancing his skills in wood carving and mechanics. Eventually, despite the job’s good salary, it was not enough to make up for not following his true passion. Finally, in 2018, Yu quit his joband returned to Chengdu to open his automata workshop.To keep himself occupied while running his workshop, he planted blueberries, raspberries and cherries. He watered, weeded and added fertilizer (肥料) every day. “Daily routines helped me calm down and inspire my creativity, which resulted in an automaton called To Observe the Autumn,” Yu says.Over time, Yu’s reputation grew and his business flourished (兴旺). Many of Yu’s creations are built with a dash of wisdom, a sprinkle of humor and are inspired by observations of real life. Yu knows that there are many more creative ideas waiting to be expressed. “It feels quite good to be fully devoted to automata creation and I am still searching for myself.”8. What can we learn from the first paragraph?A. Yu is equipped with various skills.B. Yu is a person full of sense of humor.C Yu is now gaining recognition worldwide.D. Yu is following the latest trend in handcraft.9. Why did Yu quit his job in Beijing?A. He couldn't make a living out of it.B. He wanted to pursue his own dream.C. He missed his family in Chengdu.D. He thought he had a lot experience.10. According to Yu, what contributes to his creativity as an automata artist?A. The fruits he grows.B. Success of his business.C. His devotion to the job.D. Observation from daily life.11. Which of the following can best describe Yu’s story?A. There is no end to learning.B. Great hopes make great man.C. Actions speak louder than words.D. Experience is the mother of wisdom.D12. The five passes all include ________.A. a dinner cruiseB. a magic showC. a city tourD. a trolley ride13. Accordingto the rules and restrictions, ________.A. visitors can return their ticketsB. reservations cannot be cancelledC. passes cannot be shared among usersD. users can visit attractions more than once14. To make reservations, you can ________.A. write an e-mailB. make a phone callC. send a text messageD. fill out an online form15.

黑龙江省大庆实验中学实验三部2023-2024学年高三上学期阶段考试(二)英语试题
黑龙江省大庆实验中学实验三部2023-2024学年高三上学期阶段考试（二）英语试题学校:___________姓名：___________班级：___________考号：___________一、阅读选择Long Walks in EuropeWaldstätterweg Route, Lucerne, Switzerland•Distance 71 milesThe Waldstätterweg Route is one of the safest when it comes to snowy conditions, and the views and the colours of the trees are breathtaking at the end of October. This seven-stage route spreads to the shore of Lake Lucerne, with the glaring blue water being a constant companion. Old paths and elegant routes through woods link lakeside settlements.Harz Witches Route, Lower Saxony, Germany•Distance 58 milesThe Harz Mountains have long been associated with German folklore (民俗). Harz Witches Route runs along forest tracks through Harz National Park and can be walked throughout October and beyond. The route takes in forests, Germany’s largest wooden church, and a 439-metre rope suspension bridge. It also follows the poet Goethe’s hiking route up the Brocken.GR141, Andalucía, Spain•Distance 68 milesAutumn isn’t just a good time to walk in Andalucía. The weather stays warm long after winter starts to bite further north. It’s cheaper and less crowded, too. In November, conditions are milder here and some plants continue to flower. And two newly created GR routes begin here: both are well marked, reasonably challenging, divided into six stages and walkable in a week.Menalon Route, Peloponnese, Greece•Distance 47 milesThe Menalon Route is an excellent option for autumn. Temperatures are pleasant and autumn colours are wonderful well into November. It’s a quiet time to visit, too. Nights in mountain villages are a highlight. Dimitsana, surrounded by snowy peaks, is a particular jewel. In Stemnitsa, there is a folklore museum showing the village’s jewellery-makingheritage.1．Which route may attract people who are interested in folk and local religious culture?A．Waldstätterweg Route.B．Harz Witches Route.C．GR141.D．Menalon Route.2．What can people do on Menalon Route?A．Admire colorful flowers.B．Enjoy wonderful nights.C．Learn about local festivals.D．Explore the forests.3．What do the listed four routes have in common?A．They cover similar distances.B．They require no charges.C．They suit autumn walks.D．They feature snow scenery.In my early teens, I was once given a film camera as a gift. On receiving it, I jumped on my bike, headed to Wimbledon Common and took photos, just for me: photos of trees and wildlife. I was out all day. On my way home I spotted a tree lit up by street lighting and tried to capture its splendour. Rushing home, I popped the spent film in a special little envelope and sent it off to a photography store, desperate to see how it came out. I took many photos then and loved the fact that when you processed your film you got back colour photos which froze the precious moments, gently encouraging the hobby and the payments for processing.As I grew into adulthood, that simple, deep happiness gradually faded away. One weekend when I was busy answering the work calls, my eyes caught a box in the corner of the room. I suddenly felt a sense of sadness. The stress growing over these years had pushed the camera from beside my pillow to the box in the corner. I thought I needed a change.I took out the camera and dusted it down. It was a great joy that it still worked. I bought new film and took the camera everywhere I went. Now it is always on hand to accompany me on journeys, to allow me time to myself. Even if the day is full and busy, I can seize some moments for myself to take photos, to observe the world around me.The wall of my room now holds all my camera equipment on display, along with photos I’ve taken. To me, the room represents how I’ve found happiness: by reconnecting to the younger part of myself I laid aside, by allowing room in my life for pleasure to exist, and by creating an environment that allows opportunities for delight.4．What did the author think of taking photos as a young boy?A．Inspiring and practical.B．Tiring yet delightful.C．Exciting and worthwhile.D．Difficult yet engaging.5．Why did the author stop taking photos according to paragraph 2?A．He wanted to focus on his work.B．He was struck by sudden sorrow.C．He attempted to behave like an adult.D．He was faced with increasing pressure.6．What did the author get from picking up his hobby?A．More fun in the daily routine.B．New journeys in the wild.C．Better skills of observation.D．Different styles of photography. 7．What is the best title for the text?A．Revisiting Lost Childhood MemoriesB．Appreciating Beauty Behind the LensC．Escaping Teenage Sadness with CameraD．Regaining Pleasure Through PhotographyHave you ever forgotten items when trying to recall a shopping list? Or dialled the wrong phone number when attempting to memorise one? The brain mechanisms (机制) that cause us to draw a blank in such situations have now been identified.Our working memory keeps small pieces of information that are readily accessible for planning, understanding and solving problems. But it will have “swap errors”. For example, if we are shown a red square and a blue circle, and are then asked what colour the circle was, we might say red.To understand why we make such errors, Jeff Johnston at Columbia University and his colleagues recorded the brain activity of two monkeys because a monkey’s working memory is very similar to humans’.The monkeys were shown two differently coloured squares, one above the other, for half a second. After a short delay, a black spot appeared in the same location as one of the squares, and then disappeared. The animals were trained to tell the colour of the square they were supposed to be remembering based on the location of the spot, by staring at the matching colour on a rotatable (可旋转的) wheel. When doing this for about 3 hours over multiple sessions, the monkeys performed the task correctly between 60 and 82 percent of the time, but occasionally made swap errors.The research suggests that the brain responses linked to swap errors emerged before the animals decided which colour to report. They appeared to arise during “selection” when certain items stored in working memory are enhanced at the expense of others, rather than occurring as a result of them forgetting or a failure to correctly encode (编码) items in their working memory.“Everyone assumed there were simpler explanations like failure to encode or forgetting, but this very cool study shows that working memory errors come from a previously unknown source,” says Earl Miller at the Massachusetts Institute of Technology.The team is planning further experiments to gain a better understanding of mechanisms behind swap errors. 8．What is the function of working memory?A．To identify the errors in understanding.B．To reduce the occurrence of mind blanking.C．To develop the way of distinguishing colours.D．To store information ready for mental use.9．What were the monkeys tasked with in the research?A．Correcting their errors over multiple sessions.B．Playing a matching game on a rotatable wheel.C．Reporting the colour of the square to memorize.D．Figuring out the exact position of the black spot.10．What does the research suggest about swap errors?A．They are unusual brain responses.B．They show a tendency for forgetfulness.C．They have an effect on working memory.D．They are the outcome of memoryselection.11．What is Earl Miller’s attitude towards the research findings?A．Unclear.B．Appreciative.C．Objective.D．Negative.If you want to disturb the car industry, you’d better have a few billion dollars: Mom-and-pop carmakers are unlikely to beat the biggest car companies. But in agriculture, small farmers can get the best of the major players. By connecting directly with customers, and by responding quickly to changes in the markets as well as in the ecosystems, small farmers can keep one step ahead of the big guys. As the co-founder of the National Young Farmers Coalition (NYFC, 美国青年农会) and a family farmer myself, I have a front-rowseat to the innovations among small farmers that are transforming the industry.For example, the Quick Cut Greens Harvester is a tool developed just a couple of years ago by a young farmer, Jonathan Dysinger, in Tennessee, with a small loan from a local Slow Money group. It enables small-scale farmers to harvest 175 pounds of green vegetables per hour — a huge improvement over harvesting just a few dozen pounds by hand — suddenly making it possible for the little guys to compete with large farms of California. Before the tool came out, small farmers couldn’t touch the price per pound offered by California farms. But now, with the combination of a better price and a generally fresher product, they can stay in business.The sustainable success of small farmers, though, won’t happen without fundamental changes to the industry. One crucial factor is secure access to land. Competition from investors, developers, and established large farmers makes owning one’s own land unattainable for many new farmers. From 2004 to 2013, agricultural land values doubled, and they continue to rise in many regions. Another challenge for more than a million of the most qualified farm workers and managers is a non-existent path to citizenship — the great barrier to building a farm of their own.There are solutions that could light a path toward a more sustainable and fair farm economy, but farmers can’t awkwardly put them together before us. We at the NYFC need broad support as we urge Congress to increase farmland conservation, as we push for immigration reform, and as we seek policies that will ensure the success of a diverse and ambitious next generation of farmer from all backgrounds. With a new farm bill to be debated in Congress, consumers must take a stand with young farmers.12．Why does the author mention car industry at the beginning of the passage?A．To introduce the progress made in car industry.B．To introduce a special feature of agriculture.C．To introduce a trend of development in agriculture.D．To introduce the importance of investing in car industry.13．What does the author want to illustrate with the example in paragraph 2?A．Loans to small local farmers are necessary.B．Technology is vital for agricultural development.C．Competition between small and big farm is fierce.D．Small farmers may gain some advantages over big ones.14．What is the difficulty for those new farmers?A．To gain more financial aid.B．To hire good farm managers.C．To have farms of their own.D．To win old farmers’ support. 15．What should farmers do for a more sustainable and fair farm economy?A．Seek support beyond NYFC．B．Expand farmland conservation.C．Become members of NYFC．D．Invest more to improve technology.My friend James did some first-aid training last week to learn the fundamentals of the CPR. And he asked if I’d ever done the same.“Yes,” I said, “…and no.”Because, yes, I’ve attended several resuscitation (复苏) sessions over the years. 16 In fact, despite being shown all the key information at various points in my career, I don’t think I can remember any of it now.What’s the problem? Every time I’ve had this type of training, it’s been a perfectly good opportunity to learn: an important topic, taught well, in a focused environment, with plenty to see, hear and do. I’ve always taken it seriously, too, and been focused. And I’ve always come away with a wealth of information. 17Here’s what I should have done — and what you can do now — to make sure any training doesn’t go to waste.• 18 You might be surprised to find that you’ve got some foundations of knowledge to build on. Pre-testing sparks your curiosity and puts you in a frame of mind to remember.• Challenge your recall later. 19 If it’s hard to remember, but just about possible with effort, then that’s perfect. You need that little bit of struggle to start embedding (把……嵌入) information in your brain.• Keep coming back. Put a note in your diary to test yourself again in a week, then ten days after that, then a month on…leaving longer gaps between checks. 20 Talking to James has inspired me to book myself onto yet another CPR course. But this time I’m determined to do it right. Remember that it’s the next day when the real training begins.A．Test yourself before you start.B．Wait a day, then see how much you still know.C．Stay curious about what you are eager to know.D．All the basic information has stuck in your mind.E．But no, I don’t exactly feel “trained” to save lives.F．Yet virtually nothing has ever made it to my longterm memory.G．Use the questions you wrote on the day to keep challenging yourself.二、完形填空Andrew Powell was pulling envelopes from the large mailbox outside his contemporary22．A．notice B．board C．mail D．message 23．A．by mistake B．by chance C．on purpose D．on sale 24．A．gifts B．cards C．dolls D．posts 25．A．displayed B．acquired C．designed D．decorated 26．A．came back B．wandered off C．showed up D．broke in 27．A．before B．since C．unless D．when 28．A．follow B．comment C．download D．appreciate 29．A．improvement B．possibility C．truth D．progress 30．A．difficulty B．conflict C．case D．mystery 31．A．care B．humor C．blessing D．support 32．A．artistic B．academic C．sympathetic D．realistic 33．A．suitable B．eager C．responsible D．ambitious 34．A．describing B．imitating C．celebrating D．enjoying 35．A．light B．camera C．tent D．bench三、单项选择36．______, as a matter of fact, has been put forward at the conference is ______ the government should motivate the graduates to set up their own business.A．What; that B．It; what C．What; what D．That; that 37．He suggested that the problems ______ paid special attention to.A．referred to being B．referring to being C．referred to beD．referring to be38．________ the fierce competition in finding a good job in big cities, many fresh graduates are still trying their fortune in big cities like Guangzhou City.A．Regardless of B．Apart from C．Instead of D．Because of 39．I’ll never forget the days ______ I studied hard in my senior high school, ______ changed my whole life.A．when; which B．that; which C．which; when D．when; that 40．It can be hard for you to imagine what difficulty I have had ______ the problems ______ in the meeting held last week.A．to deal with; brought up B．dealing with; bringing upC．dealing with; brought up D．to deal with; bringing up41．______ is known to all is that the old scientist, ______ Chinese people are proud of, is still devoted to advancing the medical development.A．As; whom B．What; whose C．It; whose D．What; whom 42．—Do you think it ______ to argue with them?—The question is not worthy ______.A．worthwhile; discussing B．worthwhile; to be discussedC．worthy; to discuss D．worth; to be discussed43．At that time, people ______that all species had appeared on Earth at the same time, and ______since.A．was believing; didn’t change B．believed; hadn’t changedC．had believed; hadn’t changed D．believed; haven’t changed44．The company ______ as a failure ______ into a major chemical manufacturer in the past decade.A．regarded; evolved B．regarded; has evolvedC．was regarded; evolved D．has been regarded; has evolved 45．Last Monday, I was chatting online ______, before I knew it, our manager came in and stood behind me.A．until B．as C．when D．while四、语法填空适当形式填空)47．(admit) to a university in the USA, international students must have a strong ability in spoken and written English.

2021年黑龙江省大庆实验中学高三英语上学期期末考试试卷及参考答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项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.BIn the old days, when you had to drive to a movie theater to get some entertainment, it was easy to see how your actions could have an impact（影响）on the environment. After all, you were jumping into your car, driving across town, coughing out emissions（产生排放）and using gas all the way. But now that we're used to staying at home and streaming movies, we might get a littleproud. After all, we're just picking up our phones and maybe turning on the TV. You're welcome. Mother Nature.Not so fast, says a recent report from the French-based Shift Project. According to "Climate Crisis: The Unsustainable Use of Online Video", digital technologies are responsible for 4% of greenhouse gas emissions, and that energy use is increasing by 9% a year. Watching a half-hour show would cause 1. 6 kilograms of carbon dioxide emissions. That's like driving 6. 28 kilometers. And in the European Union, the Eureca project found that data centers（where videos are stored）there used 25% more energy in 2017 compared to just three years earlier, reports the BBC.Streaming is only expected to increase as webecome more enamored ofour digital devices（设备）and the possibility of enjoying entertainment where and when we want it increases. Online video use is expected to increase by four times from 2017 to 2022 and account for 80% of all Internet traffic by 2022. By then, about 60% of the world's population will be online.You're probably not going to give up your streaming services, but there're things you can do to help lessen the impact of your online use, experts say. For example, according to Lutz Stobbe, a researcher from the Fraunhofer Institute in Berlin, we have no need to upload 25 pictures of the same thing to the cloud because it consumes energy every time. If instead you delete a few things here and there, you can save energy. Moreover, it's also a good idea to stream over Wi-Fi, watch on the smallest screen you can, and turn off your Wi-Fi in your home if you're not using your devices.4. What topic is the first paragraph intended to lead in?A. The environmental effects of driving private cars.B. The improvements on environmental awareness.C. The change in the way people seek entertainment.D The environmental impacts of screaming services.5. What does the underlined phrase become more enamored of" in paragraph 3 probably mean?A. Get more skeptical of.B. Become more aware of.C. Feel much crazier about.D. Get more worried about.6. What can we infer about the use of streaming services?A. It is being reduced to protect the planet.B. Its environmental effects are worsening.C. It is easily available to almost everyone.D. Its side effects have drawn global attention.7. Which of the following is the most environmentally-friendly?A. Watching downloaded movies on a mobile phone.B. Downloading music on a personal computer.C. Uploading a lot of images of the same thing.D. Playing online games over mobile networks.CLight pollution is a significant but overlooked driver of the rapid decline of insect populations, according to the most comprehensive review of the scientific evidence to date.Artificial light at night can affect every aspect of insects' lives, the researchers said. "We strongly believe artificial light at night — in combination with habitat loss, chemical pollution.invasive (入侵的) species, and climate change — is driving insect declines, " the scientists concluded after assessing more than 150 studies.Insect population collapses have been reported around the world, and the first global scientific review published in February,said widespread declines threatened to cause a "catastrophic collapse of nature's ecosystems".There are thought to be millions of insect species, most still unknown to science, and about half are active at night. Those active in the day may also be disturbed by light at night when they are at rest.The most familiar impact of light pollution is moths (飞蛾) flapping around a bulb, mistaking it for the moon. Some insects use the polarisation of light to find the water they need to breed, as light waves line up after reflecting from a smooth surface. But artificial light can scupper (使泡汤) this. Insects areimportant prey (猎物)for many species, but light pollution can tip the balance in favour of the predator if it traps insects around lights. Such increases in predation risk were likely to cause the rapid extinction of affected species, the researchers said.The researchers said most human-caused threats to insects have analogues in nature, such as climate change and invasive species. But light pollution is particularly hard for insects to deal with.However, unlike other drivers of decline, light pollution is ly easy to prevent. Simply turning off lights that are not needed is the most obvious action, he said, while making lights motion-activated also cuts light pollution. Shading lights so only the area needed is lit up is important. It is the same with avoiding blue-white lights, which interfere with daily rhythms. LED lights also offer hope as they can be easily tuned to avoid harmful colours and flicker rates.8. What is discussed in the passage?A. Causes of declining insect populations.B. Consequences of insect population collapses.C. Light pollution: the key bringer of insect declines.D. Insect declines: the driver of the collapsed ecosystem.9. What is the 5th paragraph mainly about?A. How light travels in space.B. How light helps insects find food.C. How the food chain is interrelated.D. How light pollution affects insects.10. What does the underlined word"analogues"in Paragraph 6probably mean?A. Selective things.B. Similar things.C. Variations.D. Limitations.11. What is the purpose of the last paragraph?A. To offer solutions.B. To give examples.C. To make comparisons.D. To present arguments.DIt was once a shoreline buried by enough garbage to make it invisible (看不见的), thus, given the unfortunate nickname "toilet bowl" . Now the Philippines' Manila Bay beach is totally different, compared with a few months ago. It happened so suddenly and extremely that it brought tears to the eyes of the local people.The cleanup started on 27 January, when 5, 000 volunteers descended on Manila Bay to remove over 45 tons (公吨) of garbage, marking the beginning of a nation-wide environmental campaign. But some two months before this great movement began, a quiet revolution was already underway.During the first week of December 2018, Brooklyn- based Bounties Network collectedthree tons of garbage from Manila Bay aver two days through a project that paid a small group of people, mostly fishermen, with a digital currency (数字货币) based on the Ethereum system.For the mostly non-bank -using Filipino fishermen, this was a first-ever experience with a digital currency. It's one that proves decisive in enabling poor communities around the world to take up arms in the fight against humanity's waste.There are signs that this recycling-for-digital payment industry may be just about to take off. Earlier in September 2018, Plastic Bank, a Vancouver -based company powered by IBM technology, also started a similar project. They set up a project in Naga, a town in southern Luzon, the country's largest island, building a collection point to let people exchange plastic and recyclable materials for digital payouts through a system.That both these pioneers have chosen the Philippines as their first location is not surprising considering the country's contribution to ocean waste. A Wall Street Journal study in 2015 revealed that the Philippines make the third-largest amount of plastic waste into global oceans.12. Why did people call Manila Bay beach“toilet bowl” ?A. It looked like a huge bowl.B. There were plenty of toilets.C. It was covered by rubbish.D. People loved the toilets here.13. What does the underlined phrase“descended on”in paragraph 2 mean?A. Completely depended on.B. Suddenly arrived at.C. Occasionally decreased to.D. Gradually disappeared from.14. What made poor communities willing to fight against waste?A. The benefits to their homeland.B. The desire to make a difference.C. The chance to escape ocean pollution.D. The experience with a digital currency.15. What is the best title for the text?A. Online system helps endocean pollution.B. Manila Bay beach is suddenly removed.C. Plastic Bank is powerful in recycling waste.D. Philippines make a great amount of waste.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。

He has always wanted to travel. “I guess I am a really restless spirit.I like traveling, so when the chance came, I jumped at it,” he says.The chance came in the form of a newspaper advertisement for work on cruise ships（游船）. At the time Estrella was the housekeeping manager at a Melbourne hotel. He applied and, after two interviews, a medical check and police clearance, the job was his.Estrella is responsible(负责的)for the cleanliness of the ship, making sure that 160 crew work properly. “I enjoy it because there is no other work-you wake up each day in a different place anda different culture. It’s exciting when you go to the next country and you don’t understand the language,” he says.Estrella likes being busy and getting to know people from all over the world. The 1,000 crew come from 94 countries, and Estrella has learnt Spanish and a little Croatian.But there is adownside. “You cannot get really drunk...because you have safety responsibilities to yourself and others,” he says. “You don’t really think about home.You start to think about home only when you get closer to your vacation and wonder what you’ll be doing.”Life on the ship is anything but cruising. Estrella and his fellows work at least 10 hours a day, seven days a week. He warns the job is not for everybody. “You have to love being busy and be prepared to work every day-and to give up drinking too much alcohol.” In his spare time, if the ship sails into a port, Estrella explores it, otherwise he works out in the crew’s gym, goes on the internet or calls home.1.Which of the following is true?A.He has been a housekeeping manager for 18 months.B.He doesn’t drink wine now.C.He cannot speak a foreign language.D.He used to be a housekeeping manager.2.The underlined word“downside”in paragraph 5 probably means ________ .A.disappointmentB.disadvantageC.failureD.loss3.In the last paragraph, the writer thinks that life on the ship is ________.A.not a tiring journey at allB.just an interesting voyageC.far from a voyage for pleasureD.more than a pleasant travel by seaBAs artificial intelligence(AI) systems become more advanced, we can expect them to be used more often in the world of human medicine and healthcare. AI is designed to imitate(模仿）the human brain in decision making and learning, so with the computing power to learn tasks in days or even hours, it is possible to create medical AIs that rapidly outperform doctors in certain tasks.Data plays a hugely important role in helping AI systems learn about human medicine. AI systems are trained on large data sets gathered from real-life cases. Providing detailed patient information in quantities is a crucial factor for their success.One of the most important areas for influencing global health is in the field of epidemiology(流行病学）。

AWhat’s best to read this year?Secrets I Know (Random House Children’s Books, ages 3-7)This tale written by Kallie George and pictured by Paola Zakimi follows a young girl and her little friend as they move from rain to sunshine, from pleasant loneliness to sweet friendship, and finally from adventures on earth to an exploration of the sky above. The colors of Zakimi’s pencildrawings are calming and George’s poetic text tells her story with simple language.Pandora (Clarion Books, ages 3-7)The award-winning author Victoria Turnbull tells the story of a little fox Pandora. Pandora lives alone. She makes herself a handsome home, but no one ever comes to visit. Then one day something falls from the sky -- a bird with a broken wing. Little by little, the bird helps Pandora feel less lonely. Turnbull’s watercolor and colored pencil drawings make this story of friendship and growth an atmospheric delight.Prince and Pirate (G.P. Putnam’s Sons Books for Younger Readers, ages 5-8)A different kind of friendship is described in this book, by Charlotte Gunnufson with pictures by Mike Lowery. Prince and Pirate are a pair of mismatched fish put into the same aquarium（水族馆). At first it seems that they’ll never learn to be friends. It’s onlywhen both take pity on a frightened dogfish that they learn the benefits of cooperation, and soon all three fish become good friends.The Giant Jumperee (Dinal Books, ages 3-5)The story was written by the award-winning British author Julia Donaldson. When Rabbit hears a loud voice bellowing（吼叫）threateningly from inside a cave, he gathers Cat, Bear and Elephant to help him decide what to do. But it’s Mama Frog who fearlessly confronts（面对）the unknown creature. Helen Oxenbury’s soft watercolors creat a beautiful countryside and her characterizations of the animals are impressive.1.

All I can do is hold on to the memories—hold on for both of us.4.When the author first saw her grandpa in hospital______.A.she gave up on himB.they were both excitedC.he didn’t recognize herD.they

this passage to______.A.show pity towards her grandpaB.record memories of her grandpaC.express deep love for her grandpaD.call on further study on Alzheimer’sCNow Hear ThisWhat do former American president Bill Clinton and rock musician Pete Townshend have in common?Both men have hearing damage from exposure to loud music,and both now wear hearing aids as a consequence.As a teenager,Clinton played saxophone in a band.Townshend, who has the more severe hearing loss,was a guitarist for a band called the Who.He is one of the first rock musicians to call the public’s attention to the problem of hearing loss from exposure to loud music.Temporary hearing loss can happen after only15minutes of listening to loud music.One early warning sign is when your ears begin to feel warm while you listen to music at a rock concert or through headphones.One later is that an unusual sound or a ringing is sometimes produced in your head after the concert.“What happens is that the hair cells in the inner ear are damaged,but they’re not dead,”says physician and ear specialist Dr.Sam Levine.According to Dr.Levine,if you avoid further exposure to loud noise,it’s possible to recondition the cells somewhat.However,he adds,“Eventually,over a long period of time,hair cells are permanently damaged.”And this is no small problem.What sound level is dangerous?According to Dr.Levine,regular exposure to noise above 85decibels(分贝)is considered dangerous.The chart below offers a comparison of decibel levels to certain sounds.Here’s another measurement you can use.If you’re at a rock concert and the music is so loud that you have to shout to make yourself heard,you’re at risk for hearing loss.That’s when wearing protective devices such as earplugs becomes critical.The facts are pretty frightening.But are rock bands turning down the volume?Most aren’t.“Rock music is supposed to be loud,”says drummer Andrew Sather.“I wouldn’t have it any other way.And neither would the real fans of rock.”Continued exposure to loud music and the failure to wear earplugs can lead to deafness, according to Dr.Levine.He states,“There’s no cure for hearing loss.Your ears are trying to tell you something.That ringing is the scream of your hair cells dying.Each time that happens, more and more damage is done.”Levels of Common NoisesNormal conversation................................................50-65dBFood blender.................................................................88dBJet plane flying above a person standing outside.........103dBRock band during a concert..........................................110-140dB8.From Paragraph1,we can learn that_______.A.loud music is a major cause of hearing lossB.famous people tend to have hearing problemsC.teenagers should stay away from school bandsD.the problem of hearing damage is widely known9.In Paragraph3,the underlined word“recondition”means______.A.not to be seenB.to make good againC.to fill with soundD.to become larger in size10.The purpose of the chart at the end of the article is to show_______.A.relationship between daily activities and hearing lossB.the noise levels of familiar soundsC.the effect of rock concertsD.a list of harmful sounds11.Which of the following statements will Dr.Sam Levine probably agree?A.Doctors know how to cure hearing loss.B.Many are taking the risk of losing hearing.C.Drummer Andrew Sather gives good advice.D.When your ears feel warm,your hair cells are dead.DIn the picture Landscape with Diogenes by the17th century French artist Poussin,the ancient philosopher Diogenes is described casting away his last possession,a drinking bowl.He realizes he doesn’t need it after seeing a youth cupping a hand to drink from a river.The significance for us is that Diogenes’spiritual descendant(后代)known as“new minimalists”are now everywhere,if not as completely possession-free as he was.There are hundreds of websites praising the virtues of tidy living.Everyone is trying to cut down on things these days.People are trying to reduce their carbon footprints,their waistlines, and their monthly outgoings.What’s more,there’s a general fear that people are becoming choked by their possessions,and this is fueled by the knowledge that the leading hobby these days seems to be shopping.It’s true,sales of e-readers and e-books go beyond those of paperbacks.As a result,the need for bookshelves is cut out.However,today’s new minimalists don’t urge us to burn our books and destroy our CDs, but just make sure we have them as digital files.So,for example,I have digitised versions of some of my old vinyl LP(黑胶)records and haven’t,as yet,stimulated myself to take the LPs to the nearest charity shop–and I admit I shall probably go on keeping them.Technology has gone beyond our dreams and there is always the doubt that our hard drives will crash and all will be lost.Far more important,however,is the fact that our memories are so inseparably tied to our possessions that we can’t get rid of stuff.We are not exactly suffering withdrawal symptoms(症状)as we try to break our addiction to objects.We are just acquiring new stuff, which means we can bin or recycle our old stuff.I’m happy to have found another website which seems to solve a whole lot of problems at once–a thriving online advice service offering storage solutions.The interior(室内的) designer responsible for this does not suggest getting rid of stuff,but rather recommends buying more stuff such as elegant flexible baskets or colourful lidded containers to hide the first lot of stuff from view.I love this philosophy–convince yourself you’ve got your desire forpossessions under control,without having to lose a thing.After all,wearen’t mercilessenough to follow Diogenes and cast away all our possessions.12.Why does the author mention a picture by the artist Poussin?A.It illustrates a modern trend.B.It describes a wise philosopher.C.Its meaning is only now becoming clear.D.Its message is not as simple as it appears.13.The author believes minimalism may not succeed mainly because of people’s______.A.resistance to media pressureziness in the face of changeck of faith in digital hardwareD.strong bond with physical objects14.According to the author,people invest in smart new storage in order to_____.A.satisfy their desire to make purchasesB.make attractive additions to their homesC.provide a temporary solution to a problemD.ease their conscience over having too many things.15.Which of the following would be the best title for the passage?A.Less is MoreB.Low Carbon Is an AttitudeC.Treasure What You HaveD.Psychology of Overconsumption.第二节(共5小题；每小题2分，满分10分)根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。
