Children’s Museum of the Arts.BThe far side of the moonis a strange and wild region, quite different from the familiar and mostly smooth face we see nightly from our planet. Soon this rough space will have even stranger features: it will be crowded with radio telescopes.Astronomers are planning to make the moon's distant side our newest and best window on the cosmic(宇宙的) dark ages, a mysterious era hiding early marks of stars and galaxies. Our universe was not always filled with stars. About 380,000 years after the big bang, the universe cooled, and the first atoms of hydrogen formed. Gigantic hydrogen clouds soon filled the universe. But for a few hundred million years, everything remained dark, without stars. Then came the cosmic dawn: the first stars flickered, galaxies came into existence and slowly the universe's large­scale structure took shape.The seeds of this structure must have been present in the dark­age hydrogen clouds, but the era has been impossible toprobeusing optical(光学的) telescopes—there was no light. And although this hydrogen produced long­wavelength(or low­frequency) radio emissions,radio telescopes on Earth have found it nearly impossible to detect them. Our atmosphere either blocks or disturbs these faint signals; those that get through are drowned out by humanity's radio noise.Scientists have dreamed for decades of studying the cosmic dark ages from the moon's far side. Now multiple space agencies plan lunar missions carrying radio­wave­detecting instruments—some within the next three years—and astronomers' dreams are set to become reality.“If I were to design an ideal place to do low­frequency radio astronomy, I would have to build the moon,”says astrophysicist Jack Burns of the University of Colorado Boulder. “We are just now finally getting to the place where we're actually going to be putting these telescopes down on the moon in the next few years.”4. What's the purpose of building radio telescopes on the moon?A To research the big bang. B. To discover unknown stars.C. To study the cosmic dark ages.D. To observe the far side of the moon.5. What does the underlined word “probe” in Paragraph 3 possibly mean?A. Explore.B. Evaluate.C. Produce.D. Predict.6. Hydrogen radio emissions can't be detected on Earth because ________.A. there was no light in the dark agesB. they cannot possibly get through our atmosphereC. gigantic hydrogen clouds no longer fill the universeD. radio signals on Earth cause too much interference7. What can we infer from theunderlined sentence in the last paragraph?A. Scientists have to rebuild the moon.B. We will finally get to the moon's distant side.C. The moon is a perfect place to set up radio telescopes.D. A favorable research environment will be found on the moon.CIt's the near future.Animal populations have fallen sharply and 80% of species are extinct.The forests are so rare that you need to make a booking to visit one. Birds also face extinction.The Arctic terns,a species evolved to fly across the world on4000kmannual journeys,are on their last migration (迁徙) to Antarctica.The Last Migrationby the Sydney-based writer Charlotte McConaghy is a different sort of climate novel,one in which the heroine's(女主人公)damaged soul is as much a story as the damaged environment This is McConaghy's first work of literary fiction,after a history publishing in science fiction and a romantic fantasy series."I wanted to try and engage with the climate crisis closely,"she said."It's hard to nail down where he book came from.But I had Toni Morrison's words in my head:'If there's a book you really want to read,but i hasn't been written yet,then you must write it.'I love that. It really speaks to me.""I wanted to write about the way the natural world is disappearing but I didn't know a way in."The way in”, she says, was to"go travelling.I went to Ireland and Iceland,and thought about these incredible journeys of the terns and these people who study hes journeys."The book became a story of a double journey: the migration of the birds,and a broken woman's travelling to the end of the earth.Much of the book is told in flashbacks, the action jumping between the south coast of New South Wales to the west coast of Ireland and to Greenland."I've always been fascinated with Ireland: the landscape, the people and the poetry and music.I was fascinated with writing a character from there. It was a way to connect more with the place."McConaghy says she also wanted to have a character who was"of two places"."I had lived in 21 houses by the time I was 21, as a result I definitely know how it feels to feel as if you are not sure where you belong and feeling as if you are between two worlds."8. How isThe Last Migrationdifferent from other climate novels?A. It forecasts environmental destruction.B. It features a bird's cross-continental migration.C It combines science fiction well with romantic fantasy.D. It attaches equal importance to the heroine's broken soul.9. What did McConaghy think of Toni Morrison's words?A. Inspirational.B. One-sided.C. Authoritative.D. Casual.10. Why did McConaghy go travelling?A. To appreciate the landscape of Ireland.B.

Eye doctors inBristolcared for the 17-year-old after his sight had gone to the point of blindness. Tests showed he had serious vitamin deficiency(缺乏). Dr. Denize Atan, who treated him at the hospital, said, “His diet was basically a portion of chips from the local fish and chip shop every day. He also used to snack on crisps and sometimes white bread and ham, and not really any fruit and vegetables.”The teenager saw his doctor at the age of 14 because he had been feeling tired and unwell. At that time he suffered from vitamin B12 deficiency, but he did not stick with the treatment or improve his poor diet. Three years later, he was taken to theBristolEyeHospitalbecause of progressive sight loss.He was not overweight or underweight, but he had lost minerals from his bones, which was really quite shocking for a boy of his age. In terms of his sight loss, he met the standards of being blind. “He had blind spots right in the middle of his sight,” said Dr Denize Atan, “That means he can’t drive and would find it reallyarduousto read, watch TV or recognize faces.”Dr Denize Atan said that parents should learn about the harm that can be caused by picky eating, and turn to experts for help. For those who are concerned , she advised, “It’s best not to be anxious about picky eating , and instead calmly introduce one or two new foods with every meal.” She said multivitamin tablets can supplement(补充) a diet, but cannot take the place of eating healthily. “It’s much better to take in vitamins through a varied and balanced diet,” she said, adding that too manycertain vitamins , including vitamin A, can be harmful ,“so you don’t want to overdo it.”12.

Ever say to yourself:Hey, I wish that I could do more to help the environment? Have you ever thought about trying to help the earth but never really did it? Well, here are some pretty easyand skillful ideas for that green - earth desire inside you.●Turn off your computer. By leaving it on all day you are creating more CO2than a regular passenger would, driving to and from work in one day.● Ride your bike or carpool (合用汽车).Obviously, youare creating less CO2which will help the ozone(臭氧).● Make a garden. Even simply grow some plants in your kitchen, which will help produce more oxygen while eating up some of that evil CO2.● Buy local groceries. It creates less impact on the environment. Besides, you're supporting your local farmers.● Recycle. You had to see this coming. But you have no idea how much you are helping the environment by simply reusing a water bottle instead of buying a huge pack at the store.● Don't run the water while brushing. It saves you money and helps the water resources.● Open the curtains. Natural light is much prettier and it will keep the energy usage down.● Rechargeable batteries. You have no idea how much it takes to get rid of batteries. Do yourself a favor. Save some money and some energy.1. If you don't want to create more CO2, you may_______.A. turn off your computer or open the curtainsB. turn off your computer or ride your bike or carpoolC. make a garden or open the curtainsD. use rechargeable batteries or make a garden2. Which of the following can best describe the function of the first paragraph?A. Main body.B. Argument.C. Lead - in.D. Conclusion.3. The main idea of the passage is about________.A. the importance of environmental protectionB. some ways about how to prevent pollutionC. some suggestions about how to save energyD. some suggestions about environmental protectionBDo you ever listen to the songs that your parents like? Chances are that you don’t. You probably think the music that they like is old and boring and that the songs on your playlist are muchcooler. But scientists found that people’s music taste changes as time goes by. So it is likely that your own musical preferences will follow a similar path to your parents’, whether you like it or not.We used to think that culture and personality (个性) are the only reasons for different music choices. But researchers at the University of Cambridge noticed that as people enter into different age groups, their social environment changes, and so does their music taste. There are some musical periods that people go through in their life.The first period comes in the teenage years, during which people like strong music such as punk and rock, because teenagers tend to be aggressive or want to be independent.But as people move into early adulthood, their lifestyles change they want to build close relationships with others. As a result, they become fonder of contemporary music, such as pop and R&.B, which is usually uplifting and danceable.When middle age comes, most people have settled down. During this period, people prefer music, such as jazz and classical, as well as music like country, folk and blues.As for old people, they prefer old songs in their childhoods. They generally listen to relaxing music, such as country music and jazz music. But you must be questioning. “Aren’t there old people who are still interested in or even crazy about rock music?” Of course there are. But their reasons for listening to rock music may have changed. At that age people may listen to remind themselves of their youth.4. What do young people usually think of the songs their parents enjoy?A. They are actually less cool.B. They are worth listening to.C. They are especially serious.D. They are hard to understand.5. How many musical periods are there that people go through in their life?A. Two.B. Three.C. Four.D. Five.6. People who want to make friends mostly prefer ________.A. jazz musicB. country musicC. rock musicD. pop music7. What is the best title for the text?A. People Have Different Opinions on MusicB. People Listen to Music for the Same ReasonC. People’s Taste in Music Changes with TimeD. People’s Lifestyle Can Be Changed by MusicCAt Aizo Chuo Hospital in Japan, employees greet newcomers, guide patients to and from the surgery area, and print out maps of the hospital for confused visitors. They don’t take lunch breaks or even get paid. Why? They’re robots!Robots have long worked in factories, helping to build cars and electronic appliances. But today’s robots don’t just do the jobs of people-they actually look and act a lot like people.Kansei, arobot from Japan, has a plastic face covering 19 movable parts. The robot can make 36 facial expressions in response to different words. Kansei shakes in fear at the word “war” and smiles when it hears the word “dinner”.Researchers in Europe are going even further with iCub, a “baby” robot. They are teaching it to speak and hold conversations.The ability to interact is crucial for robots that will one day work closely with humans says robotics professor ChrisAtkeson. “ This will require robots to understand what you say and how you are feeling and respond with appropriate emotions, ” he told WR News.Japanese scientist Minoru Asada agrees. He is building a robot called CB2 that acts like a real baby. “ Right now, it only goes, ̒Ah, ah. ̓But as we develop its learning function, it will start saying more complex sentences and moving on its own, ” Asada says. “ Next-generation robots need to be able to learn and develop by themselves.”Intelligent robot will become more important in the future, as populations age and the number of human workers declines in many countries. “ We’re going to have many more old people and not enough young people to care for them,” says robot researcher Matthew Mason. “ Technology can help the old people live at home longer, instead of going to nursing homes.”8. According to the passage, what jobs have robots already performed?A. Giving advice, answering customer questions and planning events.B. Producing factory goods, building cars and greeting customers.C. Greeting customers, producing factory goods and performing surgery.D. Building cars, driving passengers and providing directions.9. The second paragraph in this passage is mainly about?A. To explain how a robot works.B. To define what a robot is.C. To describe the functions of modern robots.D. To predict the future uses of robots.10. How does the Kansei robot react on the word “fire”?A. Use languages to warn nearby humans.B Back up its memory files.C. Activate an automatic fire alarm.D. Produce a worried look on his face.11. In Asada’s opinion, the next step for robots will be to develop_______.A. the ability to learn independentlyB. the ability to understand human commandsC. the capacity to interact with humansD. the willingness to work togetherDSome of the oldest art in human history is being damaged, scientists say. And climate change may be speeding up its loss. Newresearch reports that ancient rock art in Indonesian caves is degrading over time, as bits of rock slowly break off from the walls. It's a huge loss for human history.Salt crystals(结晶)building up on the walls are a key part of the problem, the study suggests. These salt crystals go into the cave walls, changing sizes as temperatures rise and fall. This process causes the rock to slowly break down.Salt crystals may become larger when exposed to repeated changes between wet conditions and periods of drought. These kinds of changes are expected to become more obvious as the climate continues to warm.In particular, the researchers say, climate change may cause more intense El Nino(厄尔尼诺)events in thefuture. These events can strengthen the kinds of conditions that help salt crystals form Scientists are still debating the exact influence of climate change on El Nino, a natural climate cycle that drives changing patterns of warming and cooling in thePacific Ocean.The new study, led by Jillian Huntley, examined 11 ancient cave art sites in South Sulawesi, Indonesia. The researchers found evidence of salt formation at all 11 sites. It's merely a small part There are more than 300 known eave art sites around the region. The researchers note that salt crystals may indeed be part of the problem, adding that climate change is a growing threat, one that deserves more attention.12. What is the main cause of the rocks breaking off from the wall?A. Weather patterns.B. Salt crystals.C. Wet conditions.D. Drought Periods.13. Which of the following may researchers agree with?A. El Nino events prevent salt crystals forming.B. Climate change makes little difference to El Nino.C.Salt crystals may become much larger in wet conditions.D. Constant warm weather may cause salt crystals to change size.14. Which word best describes Huntley's attitude to climate change?A. Worried.B. Curious.C. Doubtful.D. Positive.15. What can we learn from thelast paragraph?A. The formation and patterns of salt crystals.B. The impact of climate change on ancient rock arts.C. The historical value of ancient rock art in cave sites.D. The threats of human activities to ancient eave art sites.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。

2021年济南市泉城中学高三英语第二次联考试题及参考答案

2021年济南市泉城中学高三英语第二次联考试题及参考答案第一部分阅读(共两节,满分40分)第一节(共15小题;每小题2分,满分30分)阅读下列短文,从每题所给的A、B、C、D四个选项中选出最佳选项AFour Best Hikes in the WorldThere's nothing like getting out and getting some fresh air on a hike. No matter whether your idea of a hike is a leisure walk or climbing the highest mountain on Earth, we've got you covered. Below are four best hikes inthe world.Torres del Paine W CircuitLocation (位置): Patagonia. ChileDistance: 37 + milesTime: 5~6 daysBest time to go: October to JanuaryThe W Circuit is one of the most recommended hikes you'll find. Not only will you appreciate the diverse landscapes and striking granite pillars (花岗岩柱子), but you'll probably meet some new friends along the way.Grand Canyon Rim - to - Rim HikeLocation: Arizona, the United StatesDistance: 48 milesTime: 1~3 daysBest time to go: May to June, September to OctoberThere's no better way to experience one of the greatest wonders in the world. Located in one of the USA's most beautiful parks, the views are ly appealing. Just make sure you're prepared for the challenge.Trek to PetraLocation: JordanDistance: 47 milesTime: 5~ 6 daysBest time to go: October to AprilTake the road less traveled through the Kingdom of Jordan and experience one of the seven wonders of the world. Hike through canyons, gorges and ridges, and see tombs and temples along the way all while avoidingcrowds of tourists.Yosemite Grand TraverseLocation: California, the United StatesDistance: 60 milesTime: 6~7 daysBest time to go: July to SeptemberKnown for some of the best hiking in the world, Yosemite National Park is famous for its views and huge sequoia (红杉) trees. Praised byNational Geographic, the Yosemite Grand Traverse will take you through waterfalls and green mountaintops.1.Which of the following is the best time for the hike in Patagonia, Chile?A.AprilB.MayC.AugustD.December2.Where should you go for a less crowded hike?A.JordanB.Patagonia, ChileC.Arizona, the United StatesD.California, the United States3.What can you do along the Yosemite Grand Traverse?A.Plant sequoia treesB.Appreciate waterfallsC.Visit local templesD.Climb granite pillarsBPopularization has in some cases changed the original meaning of emotional (情感的) intelligence. Many people now misunderstand emotional intelligence as almost everything desirable in a person's makeup that cannotbe measured by an IQ test, such as character, motivation, confidence, mental stability, optimism and “people skills.” Research has shown that emotional skills may contribute to some of these qualities, but most of them move far beyond skill-based emotional intelligence.We prefer to describe emotional intelligence as a specific set of skills that can be used for either good or bad purposes. The ability to accurately understand how others are feeling may be used by a doctor to find how best to help her patients, while a cheater might use it to control potential victims. Being emotionally intelligent does not necessarily make one a moral person.Although popular beliefs regarding emotional intelligence run far ahead of what research can reasonably support, the overall effects of the publicity have been more beneficial than harmful. The most positive aspect of this popularization is a new and much needed emphasis (重视) on emotion by employers, educators and othersinterested in promoting social well-being. The popularization of emotional intelligence has helped both the public and researchers re-evaluate the functionality of emotions and how they serve people adaptively in everyday life.Although the continuing popular appeal of emotional intelligence is desirable, we hope that such attention will excite a greater interest in the scientific and scholarly study of emotion. It is our hope that in coming decades, advances in science will offer new perspectives (视角) from which to study how people manage their lives. Emotional intelligence, with its focus on both head and heart, may serve to point us in the right direction.4. What is a common misunderstanding of emotional intelligence?A. It can be measured by anIQ test.B. It helps to exercise a person’s mind.C. It includes a set of emotional skills.D. It refers to a person’s positive qualities.5. Why does the author mention “doctor” and “cheater” in paragraph 2?A. To explain a rule.B. To clarify a concept.C. To present a fact.D. To make a prediction.6. What is the author’s attitude to the popularization of emotional intelligence?A. Favorable.B. Intolerant.C. Doubtful.D. Unclear.7. What does the last paragraph mainly talk about concerning emotional intelligence?A. Its appeal to the public.B. Expectations for future studies.C. Its practical application.D. Scientists with new perspectives.CFew people are aware that Waterloo Bridge, crossed by thousands of daily commuters (每天长途上下班的人) and celebrated as a London landmark, was mainly built by a female workforce.There are no written or photographic records ofthe women who built the bridge since the construction company that built it closed in the 1980s and with it went all the records. What’s left is anecdotal evidence, kept alive by the tourist boat skippers who have called it theLadiesBridge.During the Second World War, with the majority of the active male labor-force away at the front, women increasingly took on traditionally male roles. By 1944, 25,000 women were working in the construction industry, carrying out back-breaking tasks. These women were permitted to carry out this exhausting and dangerous work on the basis that it would only be temporary and that their pay would be lower than that of men. So the surge (激增) in women working in construction and engineering did not continue after the war.September sees a series of events celebrating the unknown work of the large female workforce. MusicianClaudia Molitor has created a 45-minute musical entitled “theSingingBridge”, which runs at Somerset House from Sept9th. to Sept25th. In late September, the “Light up the Ladies Bridge” event saw the National Theatre’s fly tower lit up by large scale photographic projections (投影片) of female construction workers working in construction during World War II.Let’s all celebrate the women who have helped to build the cities in which we live.8. Why do few people know about the builders ofWaterlooBridge?A. The records of their work have been lost.B. Female workers received little attention.C. The construction took place long ago.D. Few people know about the bridge.9. What can we learn from the fourth paragraph?A. There are less female workers inLondon.B.WaterlooBridgeis popular among artists.C. The story ofWaterlooBridgeis better known.D. Many works of art were created during World War II.10. Why didLondonwomen do the construction work?A. It was a tradition inLondon.B. They wanted to get a steady job.C. Mostmen had gone to the battlefield.D. The company offered them better pay.11. Which can be the best title for the text?A. Female Workers on the RiseB. A Hidden Treasure inLondonC. ANew LondonLandmarkD. The Story behind theLadiesBridgeDTexas has been one of the most restrictive gun-rights states in America.Thanks to a new law,however,the state will be one of the most relaxed,to the degree that police are discouraged from even asking about someone's guns. And if they do, they may not have much power to do anything if the person refuses to show a license.To be sure, the law is strict in its own way,offering a model for regulation. Under the law, open-carry citizenshave to be licensed, a process that includes safety and shooting tests. They also have to show no prior psychological problems, and they have to be at least 21 years old.It is true that gun violence dropped sharply after restrictive laws were put in place in countries like Great Britain and Australia. However,the US public seems more interested than ever in weapons and the power they convey,despite gun control groups' concern over the increase of violence. Most states in America have steadily expanded gun rights since the end of a 10-year assault(攻击)weapons ban in 2004. Black Friday this year saw the biggest gun cache(贮存)ever purchased in one day.Considering those trends,there's a heated debate about whether the new Texas law is a model piece of legislation(立法)for a changing America,or a walking disaster just begging for trouble. As the law doesn't provide any punishment for those who refuse to show a license to a police officer, critics fear that officers may find it tough to handle potentially deadly situations. After all, armed citizens will no longer be considered suspicious, even though a lot of people might be alarmed by the sight. Most police in Texas have been told to not engage gun carriers unless they are doing something questionable or appear drunk.For sure,New Year's Day will be an exciting one for Texas gun owners. What's not yet known is how the rest of Texas will respond.12. All of the following are required in the new Texas law for open carry EXCEPTA. age limitB. mental conditionC. online registrationD. gun-operating skills13. What is mainly talked about in Paragraph 3?A. The reason for putting forward the new Texas law.B. The present situation of gun possession in America.C. The impact of the assault weapons ban in 2004.D. The inaction of the US government as to gun control.14. What do critics think the new Texas law will probably lead to?A. Heavier workload for policemen.B. Disrespect for officers.C. Lack of trust among citizens.D. Difficulty in crime prevention.15. What is the author's attitude towards the new Texas law?A. Negative.B. Cautious.C. Indifferent.D. Approving.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。

It is believed that local people hid here when the Spanish conquerors(征服者) occupied their homeland in the16th century.Canopus and HeracleionModern researchers were teased by the ancient writings about the Egyptian cities Canopus and Heracleion-where Queen Cleopatra often visited. But the cities weren’t found until 1992, when a search in Alexandria waters found that the two cities had been flooded for centuries. Artifacts(史前器物) showedthat the cities once highly developed as a trade network, which helped researchers piece together more about the last queen of Egypt. Machu PicchuA Yale professor discovered "the Lost City in the Clouds"in 1911. A combination of palaces, plazas, temples and homes, Machu Picchu displays the Inca Empire at the height of its rule. The city, which was abandoned in the 16th century for unknown reasons,was hidden by the local people from the Spanish conquerors for centuries keeping it so well preserved.TroyThe ancient city of Troy in homer's The Iliad was considered a fictional setting for his characters to run wild. But in 1871, explorations in northwestern Turkey exposed nine ancient cities layered (层叠) on top of each other, the earliest dating back to about5,000 years before. It was later determined that the sixth or seventh layer contained the lost city of Troy and that it was actually destroyed by an earthquake, not a wooden horse.1.Why did people hide in the White City in the 16th century?A.To survive the warB.To search for a lost city.C.To protect their country.D.To avoid dangerous animals2.Which of the following was related to a royal family member?A.The White CityB.Canopus and HeracleionC.Machu PicchuD.Troy3.What can we learn about Troy?A.It was built by Homer.B.It consisted of nine citiesC.It had a history of 5,000 yearsD.It was ruined by a natural disaster.BThe world's largest iceberg is floating toward South Georgia in the southernAtlantic Ocean. Scientists fear the iceberg could crash into the island and block major feeding areas for a large population of penguins and seals. If the iceberg hits the island, it could prevent the penguins and seals from reaching food supplies.The huge iceberg is named A68a. It broke away fromAntarctica's Larsen C Ice Shelf in 2017. Satellite images show the iceberg has remained in one piece. It is estimated to be about 150 kilometers long and 48 kilometers wide. It is traveling at one kilometer per hour and is on a path to hitSouth Georgiain around 30 days.This is the time of year when seals and penguins spend a lot of time caring for their young. The distance that parents have to travel to find food is crucial. That means they have to go a lot further or go around the iceberg to find sources of food.Ecologists say an iceberg crash would also disturb materials settled on the seabed, possibly polluting the surrounding seas. As the iceberg melts, it would also release large amounts of fresh water into the ocean. This could affect krill(磷虾)populations that are a major source of food for the island's wildlife. The iceberg could remain for up to 10 years and change the area's whole ecosystem. These are globally significant populations of these species. If these species fail in this particular area, then the numbers globally are going to go down quite dramatically.Professor Geraint Tarling, an ecologist at the British Antarctic Survey, said, "The breaking off of icebergs fromAntarcticais a natural process. But the process is changing with climate change. What we're seeing with models and some observations now is that this is happening at an increasing rate. And so, this might becomemore of a usual thing in the future."4. Why are the scientists worried about the coming iceberg crash?A. It will bring extremely cold weather.B. It will destroy the feeding areas of the animals.C. It will put wildlife on the island at risk of starving.D. It will prevent animals from moving to other places.5. What is paragraph 2 mainly about?A. The characteristic of the iceberg.B. The importance of the iceberg.C. The traveling speed of the iceberg.D. The forming process of the iceberg.6. What damage can an iceberg crash bring according to paragraph 4?A. Using up much fresh water.B. Polluting the surrounding farms.C. Changing the world's ecosystem.D. Affecting the number of certain species.7. How does Tarling think of the breaking off of icebergs fromAntarctica?A. It may slow down in the near future.B. It may become common in the future.C. It has a great influence on the climate.D. It helps scientists conduct a sea study.CPablo Picasso was born on October25 inMalaga. Spain in 1881. Taking after his father, Picasso shared apassion(热爱)for painting and art. Even though he wasn't the best student in school, Picasso excelled at drawing. Noticing his amazing talent, Picasso's father, an artist, taught him everything he knew. Before long, Picasso could paint and draw much better than his father. With this rich talent, Picasso paid less and less attention to his schoolwork and spent the majority of his day sketching and drawing in notepads and sketchbooks.When he was a little bit older, Picasso moved twice and was accepted into two fine art programs. However, he didn't care very much for the special techniques they taught and often wandered the streets by himself drawing the scenes around him. After moving to these two places, Picasso moved back home toBarcelonaanddecided that he would develop new techniques of art and painting based on what he saw.Later, Picasso decided to move toParis,France, where he began perfecting his own techniques of painting, drawing and other forms of art. His drawings. paintings, and an included pieces about sadness, poverty, classics and self-portraits. One of his major types of work is calledcubism(立体派),which includes art with all sizes of geometric shapes together on the piece of an. This type of art is very important because no other artists had come up with the idea before. Picasso decided to try something new, and as a result, cubismis widely accepted today as a classic style of art.Picasso inspires us to always be thinking. He tells us to think outside the box and come up with fresh new ideas that can change the world. He surely plays a significant role in the art field.8. What do we know about Picasso as a student at school?A. He hated doing his homework.B. He was very proud of his talent.C. He showed great talent for drawing.D. He was often praised by his teacher.9. What did Picasso's father do when he found Picasso's gift?A. He tried his best to help Picasso.B. He blamed Picasso for his laziness.C. He asked Picasso to finish his work on time.D. He encouraged Picasso to do better at school.10. What was Picasso's attitude towards the special techniques at that time?A. He thought highly of them.B. He took no interest in them.C. He was confused about them.D. He was concerned about them.11. What does the author tell us in the last two paragraphs?A. Picasso has great faith in art.B. Picasso has changed the world a lot.C. Picasso can do anything he wants to.D. Picasso is a highly creative artist.DBorn in 1954, Oprah Winfrey is best known for her multi-award-winning talk show as the most influential woman in the world. It's no surprise that her recognition can bring overnight sales fortune that defeats most, if not all, marketing campaigns. The star features about 20 products each year on her "Favorite Things" show. There's even a term for it: the Oprah Effect.Her television career began unexpectedly. When she was 16 years old, she had the idea of being a journalist to tell other people's stories in a way that made a difference in their lives and the world. She was on television by the time she was 19 years old. And in 1986 she started her own television show with a continuous determination to succeed at first.TIME magazine wrote, "People would have doubted Oprah Winfrey's swift rise to host of the most popular talk show on TV. In a field dominated by white males, she is a black female of big size. As interviewers go, she is no match for Phil Donahue. What she lacks in journalistic toughness, she makes up for in plainspoken curiosity, rich humor and, above all understanding. Guests with sad stories to tell tend to bring out a tear in Oprah's eye. They, in turn, often find themselves exposing things they would not imagine telling anyone, much less a national TV audience.""I was nervous about the competition and then I became my own competition raising the bar every year, pushing, pushing, pushing myself as hard as I knew. It doesn't matter how far you might rise. At some point you are likely to fall if you' re constantly doing what we do, raising the bar. If you' re constantly pushing yourself higher, higher the law of averages, you will at some point fall. And when you do, I want you to know this, remember this: there is no such thing as failure. Failure is just life trying to move us in another direction" as Oprah addressed graduates at Harvard on May 30.12. What does the Oprah Effect refer to in the first paragraph?A. the influence on talk show hostsB. the power of Oprah's opinions.C. the effect on a business.D. the audience of Oprah's talk show.13. What can be inferred about Oprah's television career?A. She must have been challenged a lotB. She gained fame as planned.C. It lives up to her parents' expectation.D. She once gave up on her choice.14. What message did Oprah give to Harvard graduates?A. Success comes after failure.B. Pushing physical limits makes no senseC. Aiming higher hurtsD. Failure is part of life.15. Which of the following best describes Oprah Winfrey?A. Friendly.B. HumorousC. Determined.D. Patient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学年济南市泉城中学高三英语第二次联考试题及答案解析第一部分阅读(共两节,满分40分)第一节(共15小题;每小题2分,满分30分)阅读下列短文,从每题所给的A、B、C、D四个选项中选出最佳选项AWhat to See InHarbinParks inHarbin: Snow Sculpture Expo on theSunIslandPark: massive and beautifully carved sculptures of snow. Ice Lantern Festival: where large ice buildings and statues constructed with lights inside that make them glow.SiberianTigerPark: The park has several large caged areas where the tigers roam freely and live as they-would in their natural environment. We enter these caged areas in a specially designed van with large windows to get a look at these beautiful beasts. Live pheasants (雉) are let loose (if you pay) in order to show you the tigers' natural hunting skills.Russian Architecture: Blessed with grace and character, the city is famous for its unique, Russian-influenced architecture. Remnants (残存) from the days when Harbin wasan important stop on the Russian Manchurian Railroad, the dome-shaped structures remind people of pre-revolutionary Russia. The strong Russian flavor continues to impact the city today due to new trade and tourism betweenHarbinandRussia.TheCentral Avenue: Passers-by only street, a perfect remaining part of the busy international business activities at the turn of the 20th century. The 1.4-km long street is a worthy museum of European architectural styles, including Baroque and Byzantine facades, Jewish architectural wonders, little Russian bakeries, French fashion houses, American snack food outlets, and Japanese restaurants.Guogeli Avenue:Harbin's second biggest shopping district dotted with Russian buildings. A tram track is still preserved in the centre of the road. The street is named after Nikolay (Vasilyevich) Gogol (1809-1852); great Russian novelist, dramatist, satirist, founder of the so-called critical realism in Russian literature, best-known for his novel MERTVYE DUSHI I-II (1842, Dead Souls).Saint Sophia Church (built in 1903): The Orthodox church is a wonderful example of Russian Architecture. We only tour the outside of the church. The inside has been turned into some painters' market and is a big disappointment to all who visit it. You are welcome to venture into the church. Entrance fees are RMB20 per person.1. From where does the author look at the tigers?A. Through the windows of his house.B. In the closed areas of tigers.C. In the areas for walking.D. In their natural environment.2. Where can visitors see the most diverse styles of architecture?A. At Ice Lantern Festival.B. On the Russian Manchurian Railroad.C. On TheCentral Avenue.D. OnGuogeli Avenue.3. When walking in the city ofHarbin, what can visitors still strongly feel?A. The Russian flavor.B. The influence of Guogeli's realism.C. The damage to Saint Sophia Church.D. The mixture of American and Japanese cultures.BIn 2015, a man named Nigel Richards memorized 386, 000 words in the entireFrench Scrabble Dictionaryin just nine weeks. However, he does not speak French. Richards’ impressive feat is a useful example to show how artificial intelligence works — real AI. Both of Richard and AI take in massive amounts of data to achieve goals with unlimited memory and superman accuracy in a certain field.The potential applications for AI are extremely exciting. Because AI canoutperformhumans at routine tasks — provided the task is in one field with a lot of data — it is technically capable of replacing hundreds of millions of white and blue collar jobs in the next 15 years or so.But not every job will be replaced by AI. In fact, four types of jobs are not at risk at all. First, there are creative jobs. AI needs to be given a goal to optimize. It cannot invent, like scientists, novelists and artists can. Second, the complex, strategic jobs — executives, diplomats, economists — go well beyond the AI limitation of single-field and Big Data. Then there are the as-yet-unknown jobs that will be created by AI.Are you worried that these three types of jobs won’t employ as many people as AI will replace? Not to worry, as the fourth type is much larger: jobs where emotions are needed, such as teachers, nannies and doctors. These jobs require compassion, trust and sympathy — which AI does not have. And even if AI tried to fake it, nobody would want a robot telling them they have cancer, or a robot to babysit their children.So there will still be jobs in the age of AI. The key then must be retraining the workforce so people can do them. This must be the responsibility not just of the government, which can provide funds, but also of corporations and those who benefit most.4. What is the main purpose of paragraph 1?A. To introduce the topic.B. To mention Nigel’s feat.C. To stress the importance of good memory.D. To suggest humans go beyond AI in memory.5. Which of the following best explains “outperform” underlined in paragraph 2?A. Be superior toB. Be equal toC. Be similar toD. Be related to6. Which of the following jobs is the most likely to be replaced?A. The writer.B. The shop assistant.C. The babysitter.D. The psychologist.7. What does the text suggest people do about job replacement of AI?A. Limit the application of AI to a certain degree.B. Get more support from the government.C. Apply for the donation from companies.D. Upgrade themselves all the time.CWhen I was trying to find a place where to spend my December holidays, I met by chance some cheap flights to Iceland. After checking just a few winter pictures of Iceland, I realized that the country, known as the land of fire and ice, during the cold months of the year could offer me experiences I had never had before.For sure you can’t miss the chance to go to Iceland in winter if your traveling wish list includes at least one of the crazy experiences Iceland can offer. Iceland in the North Atlantic Ocean is a paradise (乐园) for all those who want to see the northern lights, experience cold weather conditions and put themselves in geothermal (地热的) baths while the snow is falling on their head.The best way to move around Iceland is with a rental car. Distances are huge and public transport in winter is not really common out of the major towns. As we wanted to be even more convenient we decided to rent a small camper (野营车). Sleeping and cooking in a camper saved us a lot of driving, money and gave us the chance tobe always in the right place at the right time.There were also no locals and in many cases no tourist facilities (设备). For us, as we slept in a camper, it was easier. But for tourists traveling by normal cars it is necessary to check the opening times ofhotels and restaurants as many of them run just from June to September.It is amazing to experience how the weather is changing in Iceland. However, Icelanders prefer to stay inside their houses. They have even no time to complain about the weather in December. All they care about is Christmas. They love to decorate their houses, sing Christmas songs and eat typical Christmas food.8. Why is Iceland famous as the land of fire and ice?A. Because tourists would like to play with fire on the ice.B. Because it is too dry to easily cause fire to happen.C. Because it is hot inside a house and cold outside.D. Because there exist hot springs and freezing ice.9. What did the author think of the rented camper?A. It was not only practical but also economical.B. It was convenient but cost them more money.C. It provided the best chance to see the new country.D. It was much faster than other public transport.10. What does the last paragraph imply?A. The Icelanders prefer to live with their family.B. The joy of Christmas drives the freezing weather away.C. December is the coldest month of the year.D. The Icelanders are always positive and stay outside.11. What does this passage most probably come from?A. A textbookB. A scientific reportC. A travel magazineD. A news reportDKamikatsu, a small town in Japan, has shown the world that our garbage has far-reaching effects, and not just on our environment.Theexperiment in going zero waste started when the town built a new incinerator 20 years ago. But almost immediately, the incinerator was determined to be a health risk due to the poisonous gases when garbage was burned in it. It was too expensive to send waste to other towns, so locals had to come up with a new plan. Then the Zero Waste Academy was born, which helped perform this plan.Now Kamikatsu people separate their waste into 45 different categories. But in the beginning, it wasn't easy to convince local people to do all this work, and there was somepushback. Only after that initial education period did most residents come on board.This is all great news for waste reduction of course, but it has also had some unexpected social benefits as well. Like much of Japan, Kamikatsu's population is aging, and about 50 percent of the locals are elderly. The factthat the whole community takes their trash in to be recycled has created a local action and interaction between generations.That idea has been purposefully expanded to include a circular shop where household goods are dropped off and others can take them, and a tableware "library" where people can borrow extra cups, glasses, silverware and plates for celebrations."The elderly see this not as a waste-collection service, but an opportunity to socialize with the younger generation and to chat. When we visit them, they prepare lots of food and we stay with them for a while, we ask how they are," Sakano, the founder of the Zero Waste Academy, said.Sakano's ideas are truly revolutionary if you think about it. She's proving that community can be found through handling the stuff we no longer want and need.12. What is mainly talked about in paragraph 2?A. What harmful effects garbage burning has.B. Why garbage sorting is necessary in Japan.C. How the idea of zero waste was put forward.D. What the Zero Waste Academy functions as.13. What does the underlined word "pushback" probably mean?A. Inactive response.B. Generous reward.C. Bitter suffering.D. Beneficial guidance.14. What is a bonus of the zero waste project?A. Reducing waste.B. Creating community.C. Increasing people's income.D. Developing a new technology.15. Which part of a newspaper is this text most likely from?A. Technology.B. Health.C. Workplace.D. Lifestyle.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。
