ALondon’s Millennium Dome closed its doors on Sunday evening. In the past year people argued about the public funds spent on it and about the low attendance.The huge tent-like structure at Greenwich on the south bank of the Thames River was run by the New Millennium Experience Company (NMEC). The company allowed only 27,000 people to enter on the final day, after 37,000 visited it on Saturday.The total attendance for the year was around 6.5 million. The lowest monthly attendance was in January when only 366,420 visited the Dome.A single ticket to the Dome cost 20 pounds (US$30). But the attendance figure included thousands of children on free school visits. Others took advantage of a special 57 pounds for five people offer.Many traveled to London especially to seize their last chance to see the Body Zone. Body Zone is a collection of blue diamonds with the huge Millennium Star at its center.The Japanese bank Nomura was to have taken over the structure to run it as a leisure venture. But it withdrew last October because of lack of financial data.Among visitors on the last day, were Prime Minister Tony Blair’s wife Cherie and three of their children, Euan, 16, Nicky, 15, and Kathryn, 12.2.According to the article, a special ticket price offer was .A. a group of one thousand school children can be admitted for freeB. 57 pounds for five peopleC. US $ 30 eachD. 20 pounds each3. Japanese bank Nomura gave up bidding for the structure last October because .A. there was not enough financial dataB. the New Millennium Experience Company was competing with itC. there was public argument about the DomeD. the Japanese bank Nomura was to run it as a leisure venture4. Tony Blair’s wife Cherie visited the Dome on .A. FridayB. SaturdayC. SundayD. MondayBLet’s pretend we’re sailing down the Rhine River on a pleasure boat. The Rhine is one of the main waterways of Germany, and the river traffic is he avy. It’s interesting to watch many boats going up and down the river. But the river traffic is not nearly so interesting as the beautiful scenery along the banks and hillsides. The boat is passing many old castles. We can see people working in the vineyards(葡萄园)on the hillsides. There are vineyards as far as the eye can see. Wine from the Rhine Valley is famous all over the world.Suddenly our boat slows down and begins to turn a little. We are coming to a sharp bend in the river. On our right we can see a rocky cliff over 400 feet high. At first it looks quite ordinary, but there is nothing ordinary about it. There are many stories, poems, and songs about the cliff. We are looking at the Lorelei.Then someone on the boat begins to sing in German, the song of the Lorelei. It is a song about a beautiful siren(美女)who has lured many sailors to their deaths.The siren is supposed to sit on the rock combing her long golden hair and singing. Thesailors who hear her song forget to steer, and the current of river hurls their boats on the rocks and dashes them to pieces.Soon other people on the boat begin to sing. The beautiful song adds to special magic to the moment, and you begin to realize why so many people have made this trip down the Rhine to see the rock of the Lorelei.5. The more interesting thing to those who are sailing down the Rhine River on a pleasureboat is .A. to watch many boats going up and down the riverB. to see the beautiful scene along the banks and hillsidesC. to hear a song about beautiful sirenD. to see a beautiful siren combing her golden hair6. Which of the following is famous all over the world?A. The Rhine River.B. The River Traffic.C. Wine from the Rhine Valley.D. The Lorelei.7. We can see a rocky cliff over 400 feet high .A. on our right when coming to a sharp bendB. on the Rhine hillsidesC. from the Rhine ValleyD. on the boat8. The song of the Lorelei is about .A. the Rhine wineB. a rocky cliffC. the beautiful scenery along the Rhine RiverD. a beautiful and dangerous beautyCHappy April Fool’s DayIn celebration of the day, we have put together a list of some of the greatest hoaxes in history .They are the lies that have been designed for innocent people who are ready to believe them.INSTANT COLOR TVIn 1962 there was only one TV channel in Sweden, and in broadcast in black and white.The station’s technical expert, Kjell Stensson , appeared on the news to announce that thanks to a newly developed technology, all viewers could now quickly and easily transform their existing sets to display color reception. All they had to do was pull a nylon stocking over their TV screen, and they would begin to see their favorite shows in color. Reportedly, hundreds of thousands of people were taken in. Actual color TV transmission only started to appear in Sweden on April 1, 1970.SAN SERRIFFEIn 1977 the British newspaper The Guardian published a special seven-page supplement(增刊)in honor of the tenth anniversary of San Serriffe, a small republic located in the Indian Ocean. A series of articles affectionately described the geography and culture of this unknown nation. The Guardian’s phones rang all day as readers asked for more information about the beautiful holiday spot. Few noticed that everything about the island was made up.NIXON FOR PRESIDENTIn 1992 American National Public Radio’s Talk of the Nation program announced that Richard Nichard Nixon, in a surprise move, was running for President again. His new campaign slogan was, “I didn’t do anything wrong, and I won’t do it again.” Accompanying this announcement were audio clips(片断)of Nixon delivering his election speech. Listeners responded immediately to the announcement, flooding the show with calls expressing shock and anger. Only during the second half of the show did the host John Hockenberry reveal that the announcement was a practical joke, Nixon’s voice was copied by comedian Rich Little.9.

In a novel.D. In a textbook.DA man may usually be known by the books he reads as well as by the company he keeps.One should always live in the best company, whether it be of books or of men.A good book may be among the best of friends. It is the most patient and cheerful of companions. It always receives us with the same kindness; amusing and instructing us in youth, and comforting us in age.Men often discover their similarity to each other by the common love they have for a book just as two persons sometimes discover a friend by the admiration which both entertain for a third. There is an old proverb, “Love me, love my dog.” But there is more wisdom in this: “Love me, love my book.” The book is a truer and higher bond(纽带) of union. Men can think, feel, and sympathize with each other through their favorite author. They live in him together, and he in them.A good book is often the best container of a life preserving the best that life could think out; for the world of a man’s life is, for the most part, but the world of his thoughts. Thus the best books are treasuries of good words, the golden thoughts, which become our steady companions and comforters.Books are by far the most lasting products of human effort. Temples and statues decay(腐朽), but good books survive. Time is of no account with great thoughts, which are as fresh today as when they first passed through their author’s minds ages ago.The great and good do not die, even in this world. Preserved in books, their spirits walked abroad. The book is a living voice. It is an intellect(智者) to which one still listens.13.The writer introduces the topic of the passage by .A. describing life experience of great writersB. telling his own story of reading good booksC. presenting the best thoughts in good booksD. comparing good books to good friends in life14.What does the underlined sentence in Paragraph 3 mean?A. Readers feel sympathy for the author.B. Readers live together with the author.C. Readers and the author share the same feeling.D. Readers are the author’s companions and comforters.15.The passage mainly tells us that .A. one should have some good friendsB. one should read as many books as possibleC. one should keep company with good booksD books are the most lasting products of human efforts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。

AReading a bedtime story to his son one evening, Carl Honore noticed that he was reading very quickly. He was thinking about all the things he had to do later: check email, make phone calls, book a flight, prepare things for work, and so on. He suddenly realized that he had become caught in the trap of speed, rushing here and there, getting up early in the morning and burning the midnight oil at night. The more he thought about the fast pace of modern life, the worse he felt. He had ended up speed-reading to his son because he was so busy.As a journalist, he was curious about the phenomenon he was experiencing, so he did some research. He found that Americans now spend forty percent less time with their children than they did in the 1960s. Honore decided to write a book about the subject called In Praise of Slow. He wanted to let people know about the benefits of slowing down. He does not ask readers to throw out their TVs and become farmers. Instead, he describes the harmful effects of our love of speed in our lives, such as stress and health problems, he also explains the philosophy of the Slow Movement.A growing number of people around the world are choosing to take things easy, to do less, in order to lead a fuller life. There is even an International Day of Slowness on June 21. Cark Honore strongly believes that if people would only slow down, they would enjoy life so much more.1.According to the passage, if American parents in the 1960s spent 6 hours with theirkids, American parents now spend ___________ hours with their kids.A. 2B. more than 6C. 2.4D. 3.62.If John burned the midnight oil at night, he was ___________.A.at playB. at workC. at leisureD. at rest3.According to the passage, which statement about Carl Honore is NOT true?A.He was a news reporter.B.He read a bedtime story to his son.C.He suffered from stress and health problems.D.He was the writher of In Praise of Slow.BThe history of civil engineering(土木工程) is a very important story in the development of civilization. Civil engineers began practicing their profession four thousand years ago. Every great civilization, Egyptians, Minoan, and Romans, for instance, had the civil engineers. What is left of their work can prove that they were intelligent. These engineers of the ancient world built entire cities. They designed systems of pipes which supplied fresh water. They built water pipelines for farmlands as well as bridges of great length. The ruins of the structures tell us much about the work of early engineers.Consider the pyramids of Egypt. They are evidence that some of the earliest engineers had great scientific ability. They are also proof that those engineers could make lasting works of art and design. Although they lived thousands of years ago, the Egyptian engineers used very exact measurements. The base of the largest pyramid, the great pyramid near Gizeh, comes to within inches of being a perfect square. The pyramid is perfectly placed. Each corner points toward the exact directions of north, south, east and west. The inside of the pyramid is filled with complicated passages and tunnels. These lead to different rooms inside the pyramid.The engineers of Egypt did more than designing the pyramids. They also set up methods of moving and shaping the building materials. These were very heavy. They had to be brought from miles away and sometimes lifted several hundred feet. During the work, the engineers commanded thousands of workers. The pyramids remain as evidence of the abilities of the ancient Egyptian engineers.4.Four thousand years ago, ___________.A.people began practicing civil engineering in order to become professionalengineersB.civil engineers began putting their knowledge into practiceC.there appeared civil engineers by professionD.civil engineers got more involved in their profession5.The civil engineers of the ancient time were intelligent enough to build entirecities, including ___________.A.systems of pipes, bridges and pyramidsB.water supply systems, bridges and structuresC.pipelines systems, bridges and farmlandsD.water supply systems, bridges and pipelines for cultivation6.The base of the Gizeh Pyramid is cited by the author as a perfect example of___________.A.exact measurement adopted by the designersB.great scientific ability of the builderssting work of art and designD. a very large square7.Which of the following about the pyramids can be learned from the passage?A.Building materials were processed to meet certain requirements for their sizeand shape.B.Building materials were broken into smaller pieces of all sizes.C. There were no requirements for the size and shape of building materials.D.Egyptian engineers were not concerned with the size and shape of the buildingmaterials.CScientists have found that bee venom(毒液) can be used to develop new treatments of rheumatoid arthritis(类风湿性关节炎).They have shown the venom contains molecules (分子) that cause an increase in natural hormones(荷尔蒙) in the body. The research has raised hopes that the new treatments can help bring relief from the pain of arthritis and even prevent it from developing in the first place. The findings help to explain some stories of how patients who receive a bee sting treatment report improvement in their condition. Dr Suzana Beatriz Verissimo de Mello, a professor who led the research at the University of Sao Paulo, in Brazil, said bee venom caused increased levels of the hormones which defend against the disease.She said, “Bee venom is a complex mixture of materials that are known to cause protective responses in humans, and it has been used to treat rheumatoid arthritis for centuries. Our data shows that bee venom prevents the development of arthritis in the rabbits that are tested in the experiments.”Bee Sting Treatment is often used as a form of alternative medicine in which patients endure hundreds of stings by bees in the hope of getting better. The new research is the first time a scientific explanation has been shown for the effect. Professor Alan Silman, medical director of Arthritis Research UK, warned that it might be some time before any practical applications could be found.He said, “Knowing that when some people suffering arthritis are stung by bees their pain goes away for a short while is one thing; actually turning these early laboratory findings into a practical application is quite another.”8.What would be the best title for the passage?A.New treatments of rheumatoid arthritisB.New findings on the effect of bee venomC.New research about natural hormonesD.New applications of Bee Venom Treatment9.Bee venom can NOT be used to ___________.A.relieve the pain of arthritis for some timeB.get rid of the pain of bee sting immediatelyC.stop arthritis from growing in the first placeD.increase levels of natural hormones in the body10.What does the underlined word “applications” mean in this passage?A. A formal written request for a job, etcB. A piece of softwareC.The use of a rule or piece of knowledge in a particular situationD.Hard work and concentration on what you are doing11.It can be inferred from the passage that ____________.A.the reports of recovery from arthritis are made up by patientsB.the materials of bee venom are made up of natural hormonesC.the effect of bee venom on arthritis was studied centuries agoD.Bee Venom Treatment can be painful for the arthritis patientsDThe job of repairing the carpet was done and it was time for a last cigarette. Eddie began tapping the pockets of his overalls, looking for the new packet of Marlboro he had bought that morning. It was not there.It was as he swung around to look in his toolbox for the cigarettes that Eddie saw the lump (鼓包). Right in the middle of the brand new bright red carpet, there was a lump, a lump the size of a packet of cigarettes.“I’ve done it again!” said Eddie an grily. “I’ve left the cigarettes under the carpet!”He had done this once before, and taking up and repairing the carpet had taken him two hours. Eddie was determined that he was not going to spend another two hours in this house. He decided to get rid of the lump in another way. It would mean wasting a good packet of cigarettes, nearly full, but anything was better than taking up the whole carpet and fitting it again. He turned to his toolbox for a large hammer.Eddie didn’t want to damage the carpet itse lf, so he took a block of wood and placed it on top of the lump. Then he began to beat the block of wood as hard as he could. He kept beating, hoping Mrs. Vanbrugh wouldn’t hear the noise and come to see what he was doing. It would be difficult to explain why he was hammering the middle of her beautiful new carpet… The lump was beginning to flatten out.After three or four minutes, the job was finally finished. Eddie picked up his tools, and began to walk out to his car. Mrs. Vanbrugh accompanied him. She seemed a little worried about something.“Young man, while you were working today, you didn’t by any chance see any sig n of Armand, did you? Armand is my bird. I let him out of his cage, you see, this morning, and he’s disappeared. He likes to walk around t he house, and he usually just comes back to his cage after an hour or so and gets right in. O nly today he didn’t come back. He’s never done such a thing before, it’s most peculiar…”“No, madam, I haven’t seen him anywhere,” said Eddie, as he reached to sta rt the car.And he saw his packet of Marlboro cigarettes on the panel, where he had left itat lunchtime…And he remembered the lump in the carpet…12.What did Eddie want to do when he had finished repairing the carpet?A. To have a cigarette.B. To hammer the carpet flat.C. To put back his tools.D. To start work in the dining room.13.Why didn’t Eddie take out the thing under the carpet?A.It was impossible for him to take up the carpet once it was fitted.B.He didn’t need the cigarettes because he had some more in the car.C.It would take too long to take up the carpet and refit it.D.He intended to come back and remove the lump the next day.14.What did Eddie do with the hammer?A. He drove nails into the lump.B. He fixed his toolbox.C. He refitted the carpet.D. He flattened the lump.15.Mrs. Vanbrugh worried that ________.A. her pet was nowhere to be foundB. fitting the carpet would be expensiveC. Eddie would smoke in the houseD. Eddie hadn’t done a proper job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,并在答题卡上将该项涂黑。

贵州省贵阳市第一中学2023-2024学年高三上学期高考适应性月考卷(二)英语试题学校:___________姓名:___________班级:___________考号:___________一、阅读理解Appealing WordlesThe website game Wordle was a huge hit earlier this year, with more than two million players across many countries trying to guess its daily word. If it has sparked your interest in word puzzles, there are plenty of brilliant mobile games to test your letter skills on the Android and Apple app stores.Alphabear: Words Across Time: It is a great example. Each level starts with a grid of letters , from which you make words...and bears! The animals pop up if you use letters that are next to one another, and the bears get bigger as you spell more words. You can also unlock special powers to boost your points and time.Wordfeud: If you’re a fan of board games you might enjoy! It lets you play Scrabble-style matches against friends. If you’re really keen you can be involved in up to 30 games at once. The game also lets you mix up the board so that its bonus-score tiles appear in different places, to keep you all on your toes.Letterpress-Word Game: It is also a multi-player game, where you can play against friends or bots (game-controlled players). You have to spell out words to capture sections of the on-screen grid of letters for your colour (red or blue) before your opponent does, so it’s not just about finding one word at a time but also carefully planning your next moves.SpellTower: It is about strategy, too. It’s a wordsearch game where the letter tiles rise up from the bottom of the screen. You have to reduce the tile as quickly as you can by finding words and beating your own high scores.Some of these games use in-app purchases to unlock all their puzzles or remove adverts. They are optional — and remember, if you want to spend money, check with an adult first. 1.Which game can enable players to be rewarded with more time?A.Alphabear: Word Across Time.B.Wordfeud.C.Letterpress-Word Game.D.SpellTower.2.What do we know about Wordfeud?A.The more words you spell, the bigger the animal is.B.If you mix up the board, you have the bonus scores.C.You will be really confident about your next moves.D.You can beat your own high scores by using strategy.3.What can be inferred from the last paragraph?A.All of the games are free of charge.B.Only children can play these games.C.Young players can remove advertisements without any purchase.D.Young players should ask adults for permission if spending money.It was a sunny afternoon in June of 2023 when Anthony Perry stepped off the train at Chicago’s 69th Street station. The 20-year-old, who worked nights in a grocery store, was on his way to see his grandfather so they could go and look at a car Perry was thinking about buying.On the platform, two men were fighting fiercely. The pair fell over the edge and onto the tracks. One man ended up on his back, starting trembling. The aggressor leaped backward, ran back up onto the platform and disappeared. The man had fallen atop the third rail, the conduit (导电管) for the 600 volts of electricity that powered Chicago’s L trains and trembled terribly as the current went through his body. Without hesitation, Perry ran quickly to the victim. The guy looked dead, his body still shaking, his head hitting against a steel rail.Perry wondered how he was going to escape the situation he’d just put himself into. Putting his trust in God, Perry reached down and grasped the victim’s wrist. Instantly, he felt a blast of electric shock shoot through his body. Perry jumped back, reached down a second time, and was shocked again.Perry was no expert, but for a few moments he worked on the man’s heart until the victim became conscious. Doctors and firefighters arrived. So Perry let the professionals take over. His heart still racing from the adrenaline (肾上腺素) and the electric shocks, he climbed back up onto the platform, grabbed his things and continued on to his grandfather’s. As planned, they went to look at the car he wanted to buy, but it had been sold.The evening news reported the incident, crediting an anonymous hero with saving the victim’s life. After a friend posted his story on the media, Perry became the toast of Chicago. Just days after the incident, a local philanthropist (慈善家) rewarded him with a car. Perry was then recruited by the Chicago Fire Department and is now training.4.What does Paragraph 2 mainly tell us about?A.How scared the victim was.B.How strong-willed Perry was.C.How cruel the aggressor was.D.How serious the situation was. 5.Which of the following best describes Perry?A.Brave and warm-hearted.B.Adventurous and easy-going.C.Determined and energetic.D.Generous and cooperative.6.What is the author’s purpose in writing the text?A.To make us advocate heroic deeds.B.To tell a story about a hero saving a life.C.To appeal to readers to learn from Perry.D.To teach people the way to become famous.7.What do we know about Perry from the passage?A.He was badly injured in the accident.B.He cared little about his heroic behavior.C.His grandfather had passed away before he arrived.D.He had worked for the Chicago Fire Department before.It’s natural that people want to use the latest innovations to better themselves. Smart devices can truly do incredible things and help to simplify our day. They can also enhance our perceptions, arm us with knowledge, and open up a world of new possibilities. A few people have even decided to make the leap and transform themselves to become cyborgs.Cyborg is a term used to describe a being that is half human and half machine. This may sound like something out of science-fiction films, but some people have already adopted this lifestyle. One is artist Neil Harbisson. He was born completely color-blind, and could only see black and white images. It seemed that he would never experience colors. After attending a cybemetics (神经机械学) talk in college, he met an inventor who agreed to make a special device for him. They designed an eyeborg, a mechanical eye that converted colors into sound frequencies. This enabled Harbisson to hear colors and perceive the world in a different way. He started going to museums to “hear”classic paintings. In fact, a simple walk down a grocery store filled with colorful products produces some catchy tunes (动听的曲调), Harbisson loves his eyeborg so much that he rarely takes it off. He now gives talks urging others to consider adding their own mechanical improvements.British scientist Kevin Warwick conducted his own experiment in 1998. He implanted a chip inside of his arm, which he used to control lights and other appliances at home. He later expanded the project by placing electrodes inside his nervous system and linking it to the Internet. This allowed him to control external objects including robotic arms and loudspeakers. His work remains influential as this example of extended sensory input was the first of its kind.If you’re interested in becoming a cyborg and you’re willing a good place to start, it might be with a pair of Google Glass. Users wear it like ordinary eyeglasses. Using voice commands you can have it take pictures of what you see, see directions right in front of you, or translate your voice into other languages. Hopefully this experience will help you decide whether becoming a cyborg is right for you, or if you’re content to remain a human like the rest of us.8.What can we know about the eyeborg from Paragraph 2?A.It is a machine which is half human eye and half machine.B.It is a device that converts hearings into colors for color-blind.C.It makes the color-blind perceive colors by hearing sound frequencies.D.It enables the color-blind to identify colors by creating classic paintings.9.How is the passage developed?A.By comparison.B.By classification.C.By giving examples.D.By listing data.10.What is probably the author’s attitude to the experience of being a cyborg?A.Positive.B.Skeptical.C.Indifferent.D.Ambiguous.11.What is the passage mainly about?A.Why do cyborgs make our world colorful?B.Why do many people want to have eyeborgs?C.How does innovative technology improve people’s lives?D.How does technology promote the development of cyborgs?The University of Washington and University of California San Diego researchers have found that smartphones are capable of detecting blood oxygen saturation (饱和) levels down to 70 percent — the lowest value pulse oximeters (脉搏血氧仪) should be able to measure.The proof-of-principle research involved participants placing their fingers over the camera and flash of a smartphone, which uses a deep-learning algorithm (算法) to interpret blood oxygen levels.“When we delivered a controlled mixture of nitrogen (氮气) and oxygen to six subjects to artificially bring their blood oxygen levels down, the smartphone correctly predicted whether the subjects had low blood oxygen levels 80 percent of the time,” said co-lead author Jason Hoffman of the study published in npj Digital Medicine. “Other smartphone apps that do this were developed by asking people to hold their breath.But people get very uncomfortable and have to breathe after a minute. With our test, we’re able to gather 15 minutes of data from each subject. Our data shows that smartphones could work well.”Another benefit of measuring blood oxygen levels on smartphones,which almost everyone has, is their ubiquity. “It is common for you to have multiple measurements with your own device at either no cost or low cost,” added co-author Dr. Matthew Thompson.To gather data to train and test the algorithm, the researchers had each participant wear a standard pulse oximeter on one finger and then place another finger on the same hand over the camera and flash of a smartphone. The researchers used data from the participants to train a deep-learning algorithm to pull out the blood oxygen levels. The remainder of the data was used to confirm the method and then test it to see how well it performed on new subjects. The team hopes to continue this research by testing the algorithm on more people.12.What did the researchers do concerning the six subjects according to Hoffman?A.They asked them to hold their breath.B.They lowered their blood oxygen levels.C.They allowed them to breathe every minute.D.They collected 15-minute data from them in total.13.What does the underlined word “ubiquity” in Paragraph 4 probably mean?A.Being unique in shape.B.Being changeable frequently.C.Being stable in quality.D.Being present in many places. 14.What was each participant required to do during the study?A.Train and test a deep-learning algorithm.B.Keep an eye on their blood oxygen levels.C.Wear a regular pulse oximeter on every finger.D.Put a finger over a smartphone’s camera and flash.15.What would be the best title for the text?A.Smartphones Can Measure Blood Oxygen LevelsB.Smartphones Can Control Blood Oxygen LevelsC.A Deep-learning Algorithm Can Learn from Pulse OximetersD.A Deep-learning Algorithm Can Be Added to Pulse Oximeters二、七选五5 REASONS WHY LISTS ARE GREAT!10 Ways to Lose Weight. 8 Habits of Highly Successful People. 6 Ways to Get Rich Fast.16 .In fact, most online articles seem to be made up of lists.

贵州省贵阳市第一中学2023-2024学年高三上学期1月考英语试卷

贵州省贵阳市第一中学2023-2024学年高三上学期1月考英语试卷学校:___________姓名:___________班级:___________考号:___________一、阅读理解The European Towns and Cities That Are Magical at Christmas Hallstatt, AustriaThe town of Hallstatt and its beautiful landscape enjoy UNESCO protection. The old townhouses, tiny lanes and snow make this the ultimate destination forgetting into the festive mood. Hallstatt’s Christmas market is the stuff of legend. Picture a brightly lit tree and stalls selling decorations and handicrafts and you’re halfway to imagining just how special this spot is.Valkenburg, NetherlandsValkenburg has much of the usual European Christmas charms to attract visitors. However, what makes it special is the fact that they can all be found underground. The town’s Christmas Caves have become internationally renowned, with a wide range of stalls selling festive gifts and decorations. The larger Municipality Cave is home to one of the largest indoor Christmas markets in Europe.Wroclaw, PolandWroclaw is regarded as one of Poland’s most beautiful cities, but it takes things to another level at Christmas. The city’s Christmas market is home to over 250 stalls and a superb fair. The architecture here captures the Christmas feeling too, with Gothic structures meaning everyone can tap into the special feeling that only comes round at this time of year. Gothenburg, SwedenGothenburg is full of festive surprises for those willing to risk traveling north and brave the Scandinavian chill. And chief among them is the Liseberg Christmas Market. Set in an amusement park celebrating its100th anniversary in 2023, visitors can enjoy rides here and taste delicacies (佳肴) from across the country, including pickled herring, reindeer and spiced wine.1.Which of the following places has underground Christmas charms?A.Hallstatt.B.Valkenburg.C.Wroclaw.D.Gothenburg. 2.What do the listed places have in common?A.They have amusement parks.B.They feature Gothic buildings.C.They provide Christmas markets.D.They enjoy UNESCO protection. 3.Which section of a newspaper is this text most likely from?A.News.B.Business.C.Nature.D.Travel.Splendid straw-made miniatures (缩微模型) of classic ancient buildings decorate Xu Jian’s home. They range from the Yellow Crane Tower to Forbidden City’s turrets. They are all full of details and delicately crafted, tied and arranged by Xu’s hands from countless sorghum straws (高粱杆).The craft involves carving grooves (沟槽) into the sorghum straws, before multiple straws are locked together through those identically sized grooves, Xu says, adding that the sorghum straw art requires a great deal of patience, especially for works depicting ancient architecture.Under the influence of his father Xu Yanfeng, Xu Jian got his hands on sorghum straws in childhood. He still vividly remember show his father would follow a film featuring scenes of Tiananmen Square and then note down all the details before creating a delicate miniature of it for over three years. The work was then sent to Japan for exhibition and collected by a local museum. Ever since, many of his father’s works made their way to exhibitions at home and abroad.Xu Jian became committed to the art after he reached 19, getting into the depth of the related techniques. “My father urged me to keep in mind traditional Chinese architectural skills and the history of traditional building protections, and to apply them to my own sorghum straw artworks,” he says. Through hands-on guidance from his father, Xu Jian’s skills became increasingly proficient. While inheriting the craftsmanship from his father, Xu Jian has produced his own creative works.To date, Xu Jian’s works have been exhibited in over 40 provincial and national-level exhibitions, earning numerous gold awards. To promote the art, Xu Jian joined hands with the School of Civil Engineering, Hebei University of Science and Technology, in 2013, and founded a sorghum straw carving and tying base where the art has been integrated with architectural courses to enhance students’ thinking and practical skills.4.What’s the feature of Xu Jian’s miniatures?A.They are made from rare materials.B.They are skillfully created by hand.C.They are sold in the Forbidden City.D.They are identical to ancient buildings.5.What can we infer about Xu Yanfeng from the text?A.He showed great perseverance.B.He was fond of watching films.C.He won popularity only in China.D.He attached importance to creativity.6.Why did Xu Jian establish a sorghum straw carving and tying base?A.To exhibit his artworks.B.To assist a university.C.To accommodate artists.D.To spread craftsmanship.7.Which of the following can best describe Xu Jian?A.Patient and innovative.B.Generous and productive.C.Caring and strong-willed.D.Critical and open-minded.Does work ever leave you feeling stuck in a boring way of life with limited opportunities to be creative? To thrive (成长), you might want to increase your brain’s flexibility. But is this even possible, and if so, how?Most jobs require the ability to problem-solve and cope with challenges, at least to a certain extent. Imagine a teacher who has a new and very nervous student in their class. If that teacher is a flexible thinker, they will be able to adapt their classroom management, even if they haven’t seen this situation before. According to Leonard Mlodinow, author of Elastic, flexible thinkers rely on idea generation and imagination — they are willing to experiment and take risks. “Elastic (灵活的) thinking is what you need when the circumstances change, and you are dealing with something new. It’s not about following rules.” Therefore, instead of following the typical procedure for handing a new student, the teacher might come up with a tailored response, based on prediction and previous experience.So, how can you become a more flexible thinker? According to Dr. Lisa Feldman Barrett, it’s all about exercising the brain. One way of doing this, she says, is through exposure to a variety of experiences which make it easier to adjust to new situations. A lot of companies now consider flexible thinking in the workplace, especially when it comes to design. Workspaces may have couches where workers can lie down and relax, giving them the spaceto come up with and process new ideas. Mlodinow says it’s very important to take time today dream, listen to ideas and concepts you disagree with and spend time doing activities outside of your comfort zone. This will help you understand multiple opinions and therefore blossom in many different aspects of your career.In a word, if you want to make a change, you can become a flexible thinker too, with a little practice.8.What may a flexible thinker be like?A.Fond of challenges.B.Good at teaching students.C.Willing to follow rules.D.Able to make quick responses. 9.How can you become a flexible thinker according to Dr. Barrett?A.By learning to design.B.By adjusting to new procedure.C.By doing more exercise.D.By experiencing various situations. 10.Why is it important to do activities outside of your comfort zone?A.It helps you test your flexibility.B.It helps you succeed in your work.C.It helps you handle disagreement.D.It helps you identify good opinions. 11.Which of the following is a suitable title for the text?A.A Wonderful Journey to Flexibility B.Changes Make Flexible ThinkersC.How to Get Out of Boring Life D.Ways to Make a Positive ChangeOfficials of Detroit, Michigan, have equipped apiece of road with new technology designed to charge electric vehicles (EVs) on the path. The roadway is meant to serve as a demonstration project for the technology, which could be expanded to larger road systems.The system uses a series of copper wires placed underneath the road. These wires have the ability to send electricity through a magnetic field to charge an EV’s battery. Charging can happen while the car is driving or sitting above the equipment. Elect re on says the electric road system is safe for people and animals walking over it and does not harm drivers.The technology was created by Electreon, a developer of wireless charging solutions for EVs. Stefan Tongur, Electreon’s vice president of business development, told The Associated Press EVs require special equipment to receive the wireless signal. “The technology is smart,” Tongur said, and “knows who you are...”The electrified road stretches about one half-kilometer. It will be used to test and improve the technology in preparation for wider releases. Tongur said the project aims to“demonstrate how wireless charging unlocks widespread EV adoption, addressing limited range, grid (电网) limitations, and battery size and costs.” He looks forward to a future in which, in his words, “EVs are the norm, not the exception.”Michigan’s Department of Transportation (DOT) signed a five-year agreement with Electreon to develop the roadway charging system. Offcial shave said they plan to build another electrified stretch of road in another part of the city. Michigan transportation officials say the wireless-charging roadway project has helped position the state and city of Detroit as national leaders in EV technology. “In Michigan, we want to stay ahead of the curve,” Michigan DOT Director Bradley C.Wieferich told the AP.12.What is the new technology intended to do?A.Provide power for EVs.B.Demonstrate a project.C.Expand road systems.D.Improve EVs’ batteries.13.What can we learn about the electric road system?A.People and animals may get an electric shock near it.B.EVs are charged through contact with its copper wires.C.It charges EVs only if they stay still on the equipment.D.A special device is needed to pick up its wireless signals.14.Which of the following can best replace the underlined phrase “stay ahead of the curve”?A.Develop more smoothly.B.Make progress in the industry.C.Take the lead in the field.D.Achieve a goal ahead of time. 15.What is Bradley’s attitude towards the project?A.Skeptical.B.Tolerant.C.Favorable.D.Objective.How to Change Limiting BeliefsHave you ever felt trapped by thoughts like “I’m not good enough” or “I can’t achieve that”? 16 . But it is possible to change your limiting beliefs and start living a happier and healthier life.1. Know your limiting beliefsWe’re often not even conscious of our limiting beliefs. 17 Make a habit of carrying a notebook and pen around with you for the next week. Notice when your mood changes for the worse or when you’re feeling particularly down.2. Collect the evidenceOnce you’ve discovered what your limiting beliefs are, start collecting evidence that disproves the limiting beliefs. If you think about this properly, you’ll find that there is a lot of evidence out there. 18 On the contrary, you will realize there is very little evidence to support those beliefs.3. 19Repetitive thoughts form our beliefs and so it’s essential to start making your internal dialogue positive, rather than negative. Over time this will become automatic, and you will start to form healthier beliefs about yourself.4. Take actionTaking action is the single most important tool when it comes to making any sort of change in your life. Knowledge, without action, is worthless. Taking action to change your life is a choice. 20 . It takes effort and determination.A.There’s no quick fixB.There is no substitute for taking actionC.Trade your limiting belief for an empowering statementD.You’ve just been unconsciously ignoring it your whole lifeE.For each limiting belief you have, turn it into a positive affirmationF.These are known as limiting beliefs, stunting (阻碍) our potentialG.Because we believe them to be a reality, we don’t recognize them for what they are 二、完形填空fully open.

ALondon’s Millennium Dome closed its doors on Sunday evening. In the past year people argued about the public funds spent on it and about the low attendance.The huge tent-like structure at Greenwich on the south bank of the Thames River was run by the New Millennium Experience Company (NMEC). The company allowed only 27,000 people to enter on the final day, after 37,000 visited it on Saturday.The total attendance for the year was around 6.5 million. The lowest monthly attendance was in January when only 366,420 visited the Dome.A single ticket to the Dome cost 20 pounds (US$30). But the attendance figure included thousands of children on free school visits. Others took advantage of a special 57 pounds for five people offer.Many traveled to London especially to seize their last chance to see the Body Zone.

The Rhineis one of the main waterways of Germany, and the river traffic is heavy. It’s interesting to watch many boats going up and down the river. But the river traffic is not nearly so interesting as the beautiful scenery along the banks and hillsides. The boat is passing many old castles. We can see people working in the vineyards (葡萄园)on the hillsides. There are vineyards as far as the eye can see. Wine from the Rhine Valley is famous all over the world.Suddenly our boat slows down and begins to turn a little. We are coming to a sharp bend in the river. On our right we can see a rocky cliff over 400 feet high. At firstit looks quite ordinary, but there is nothing ordinary about it. There are many stories,poems, and songs about the cliff. We are looking at the Lorelei.Then someone on the boat begins to sing in German, the song of the Lorelei. It is a song about a beautiful siren(美女)who has lured many sailors to their deaths.The siren is supposed to sit on the rock combing her long golden hair and singing. The sailors who hear her song forget to steer, and the current of river hurls their boats on the rocks and dashes them to pieces.Soon other people on the boat begin to sing. The beautiful song adds to special magic to the moment, and you begin to realize why so many people have made this trip down the Rhine to see the rock of the Lorelei.5. The more interesting thing to those who are sailing down the Rhine River on apleasure boat is .A. to watch many boats going up and down the riverB. to see the beautiful scene along the banks and hillsidesC. to hear a song about beautiful sirenD. to see a beautiful siren combing her golden hair6.

The station’s technical expert, Kjell Stensson , appeared on the news to announce that thanks to a newly developed technology, all viewers could now quickly and easily transform their existing sets to display color reception. All they had to do was pull a nylon stocking over their TV screen, and they would begin to see their favorite shows in color. Reportedly, hundreds of thousands of people were taken in. Actual color TV transmission only started to appear in Sweden on April 1, 1970. SAN SERRIFFEIn 1977 the British newspaper The Guardian published a special seven-page supplement(增刊)in honor of the tenth anniversary of San Serriffe, a small republic located in the Indian Ocean. A series of articles affectionately described the geography and culture of this unknown nation. The Guardian’s phones rang all day as readers asked for more information about the beautiful holiday spot. Few noticed that everything about the island was made up.NIXON FOR PRESIDENTIn 1992 American National Public Radio’s Talk of the Nation program announced that Richard Nichard Nixon, in a surprise move, was running for President again. His new campaign slogan was, “I didn’t do anything wrong, and I won’t do it again.” Accompanying this announcement were audio clips(片断)of Nixon delivering his election speech. Listeners responded immediately to the announcement, flooding the show with calls expressing shock and anger. Only during the second half of the show did the host John Hockenberry reveal that the announcement was a practical joke, Nixon’s voice was copied by comedian Rich Little.9. Which of the following countries is NOT mentioned in the text?A. IndiaB. the UKC. the United StateD. Sweden10. Who worked as a host on the radio?A. Kjell StenssonB. Rich LittleC. Richard NixonD. John Hockenberry11. When did the small republic San Serriffe come into being?A. In 1962B. In 1977C. In 1992D. Never12. Where can we probably read this article?A. In an ad.B. In a magazine.C. In a novel.D. In a textbook.DA man may usually be known by the books he reads as well as by the company he keeps. One should always live in the best company, whether it be of books or of men.A good book may be among the best of friends. It is the most patient and cheerful of companions. It always receives us with the same kindness; amusing and instructing us in youth, and comforting us in age.Men often discover their similarity to each other by the common love they have for a book just as two persons sometimes discover a friend by the admiration which both entertain for a third. There is an old proverb, “Love me, love my dog.” But there is more wisdom in this: “Love me, love my book.” The book is a truer and higher bond(纽带) of union. Men can think, feel, and sympathize with each other through their favorite author. They live in him together, and he in them.A good book is often the best container of a life preserving the best that life could think out; for the world of a man’s life is, for the most part, but the world of his thoughts. Thus the best books are treasuries of good words, the golden thoughts, which become our steady companions and comforters.Books are by far the most lasting products of human effort. Temples and statues decay(腐朽), but good books survive. Time is of no account with great thoughts, which are as fresh today as when they first passed through their author’s minds ages ago.The great and good do not die, even in this world. Preserved in books, their spirits walked abroad. The book is a living voice. It is an intellect(智者) to which one still listens.13.The writer introduces the topic of the passage by .A. describing life experience of great writersB. telling his own story of reading good booksC. presenting the best thoughts in good booksD. comparing good books to good friends in life14.What does the underlined sentence in Paragraph 3 mean?A. Readers feel sympathy for the author.B. Readers live together with the author.C. Readers and the author share the same feeling.D. Readers are the author’s companions and comforters.15.The passage mainly tells us that .16. A. one should have some good friendsB. one should read as many books as possibleC. one should keep company with good booksD books are the most lasting products of human efforts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。

But shifting climate patterns have delayed when the birds begin to migrate, and they are now reaching the mountains too late to make it over the peaks, locking them in an icy death trap. Determined to save them, Mr. Fritz decided he would teach the birds a new, safer migration route by guiding them himself in a tiny aircraft. And he was confident he could succeed in this daring, unusual plan —because he had done it before.Mr. Fritz was his young pupils’ only provider of food and love since they’d been just a few days old, and the ibises eagerly followed their teacher. He learned to fly, modifying a tiny aircraft so it would fly at speeds slow enough for his winged students to keep up. In 2004, three years after some experiments, Mr. Fritz led the first flock from Austria to Italy, and has since led 15 such migrations. Over that time, he has rewilded (放归) 277 young ibises, many of which then started to pass the route on to their own young. For now, however, the mainworry is getting the birds to follow the aircraft. “While they have a strong bond with their ‘mothers’ and follow them around on the ground, flying is more difficult,” Fritz said.“Fly Away Home was a huge hit with us biologists,” Mr. Fritz said, recalling the 1996 movie in which a Canada geese was led to migrate by an aircraft. When Mr. Fritz claimed he’d do the same with the ibises, he was initially laughed at. But through years of trial and error, he succeeded. He even learned to fly like a bird, he said, laughing with ease. Mr. Fritz’s two sons, both now teenagers, followed their flying father and the migrating birds on the ground, and his family and colleagues witnessed the risks he was taking. But the unexpected risks are “necessary”, Mr. Fritz said.“It’s not so much a job,” he added, “but my life’s purpose.”4.What made Mr. Fritz believe he would make it this time?A.Confidence.B.Experience.C.Bravery.D.Determination. 5.What is Fritz’s present concern according to paragraph 3?A.Whether the birds can fly after the aircraft.B.Tight schedule to modify a tiny aircraft.C.The extreme weather that prevents flying.D.Limited support from the local government.6.How is Mr. Fritz according to the passage?A.Imaginative and out-going.B.Generous and easy-going.C.Purposeful and strong-willed.D.Energetic and open-minded.7.What can we know from paragraph 4?A.Mr. Fritz once starred in a film in 1996.B.Mr. Fritz was favored by those around him.C.Mr. Fritz had no difficulty with what he did.D.Mr. Fritz thought what he did was worthwhile.There was a lot of news related to artificial intelligence, or AI, and machine learning. Among the stories were two dealing with direct competitions between humans and machines.In one competition, machines that used AI performed better than human beings in a high-level reading test. Two natural language processing tools beat humans in the experiment. One of the tools was built by the American technology company Microsoft. The other was created by Chinese online seller Alibaba Group.In another competition, a computer took on humans in live, public debates.The event demonstrated how AI-powered computers are increasingly being developed to think and sound like humans. The organizer of the debates, U. S. technology company IBM, announced split results. It said a majority of those watching said they felt the machine had done more to improve their knowledge of the subject. But, the human got more praise for communicating their ideas.This year, we also explored the many ways AI and machine learning are now being used. For example, some U. S. judges use machine learning systems to help them decide when, and for how long, criminals should be jailed. The system uses computers to examine data from thousands of court cases.One fast-growing area of AI is facial recognition, which is increasingly being used for security purposes. Recently, Atlanta’s Hartsfield-Jackson airport became the first in the U. S. to permit passengers to use fa cial recognition technology to get on flights. A Chinese company showed off an AI system it developed to recognize individuals by body shape and walking movements. The system is already being used by Chinese police in Beijing and Shanghai.In addition, machine learning was used during 2018 to predict results of the World Cup soccer competition. The technology also created artwork that was sold for a large amount of money. And it is being used to help farmers save time and money, while reducing environment-harming chemicals. Other technology systems are being used to follow farm animals and wildlife to collect information on their activities.8.What can we infer from the second paragraph?A.AI is perfect in all aspects.B.Humans will be replaced sooner or later.C.AI is the biggest threat to the human beings.D.AI is more competent than humans in some areas.9.Which of the following AI can’t do at present according to the passage?A.Creative thinking.B.Facial recognition.C.Collecting information.D.Predicting results of the games. 10.What do the last three paragraphs mainly talk about?A.The disadvantages of AI.B.The application of AI.C.The future of AI.D.The experiments of AI.11.What’s the attitude of the author to AI?A.Supportive.B.Unclear.C.Doubtful.D.Opposite.Like the rest of us, scientists have long suspected the healing capacity of a good hug. Unlike the rest of us, they’ve gone about trying to prove it.“Laboratory studies suggest that things like hugs help us feel safer. They can also make us less sensitive to physical pain and less reactive when we’re faced with threatening experiences,” says Michael Murphy. He is a research professor in the Department of Psychological Sciences at Texas Tec h University. “This lab work has shown that hugs and other touch behaviors are related to stress. The more stress we have, the more our heart rates and blood pressure go up. At this time, hugs and other forms of personal touch may give off all sorts of feel-good chemicals, so that stress can be reduced.”“There’s a lot that we still need to learn, and there’s a lot we don’t know,” Murphy says. “However, what seems to be rising up is that hugs, as well as other forms of loving and gentle touch, are really powerful. They remind people that they’re cared about and that they have someone in their corner.”“We expect touch. When we were born, we were placed in our mothers’ arms almost immediately. In that first year of our life, we spend a lot of time being held by other people. And as we grow up, we seek out hugs and touch as a way of connection. I think what we have lost in the past few years are these really easy opportunities to be reminded of connection.”While he was at Carnegie Mellon, Murphy was the lead author of a hug-centered 2018 article in the scientific journal PLOS One. In a series of interviews with 404 adults over a two-week period, the researchers found that receiving a hug is associated with the attenuation of negative emotions that occur on days with interpersonal conflicts. That is to say, generally, hugs help to reduce the negative impacts that personal conflicts may cause in our daily lives. 12.According to the passage, what do laboratory studies suggest about the effects of hugs?A.Hugs can make us more sensitive to physical pain.B.Hugs can increase our heart rates and blood pressure.C.Hugs can reduce stress and release feel-good chemicals.D.Hugs have no impact on our emotional well-being.13.What does the underlined word “They” in the 3rd paragraph refer to?A.Only hugs.B.Any forms of touch.C.People who are touched.D.All kinds of loving and gentle touch. 14.What is the purpose of seeking hugs and touch as we grow up?A.To help us feel connected to others.B.To develop physical strength and coordination.C.To increase sensitivity to interpersonal conflicts.D.To decrease the need for emotional connection.15.What is the main idea of the passage?A.Hugs have little impact on our physical well-being.B.Hugs can reduce stress and negative emotions.C.Hugs can only be beneficial during the conflicts.D.Hugs are a way of physical pain relief.You can never see any improvement if you stick to your comfort zone. So challenge the following limits:Figure out what you’re scared of and do it continuously.If you’re a salesman, and you’re scared of talking to people personally or over the phone, now, instead of being scared and thinking you’ll fail, spend at least five minutes a day picking up the phone and making a call. Someone may hang up on you. 17Eventually, you can look at fear in the eyes and say, “Go on, I’m not scared!”Take a class for a hobby you’ve been wanting to develop.Make sure this hobby is not linked to your career; you have to relax and relieve your stress while performing this. 18Apart from helping you challenge yourself, taking a class for your hobby may also give you extra income.Set aside at least nine minutes a day for physical exercise.You don’t need to go to the gym. 19 Exercise can not only help you maintain your regular weight, but also make you feel better about yourself.20Don’t just limit yourself to your fellow travelers — try to connect with the service staff.You never know what kind of people they’re going to be. Get out of your house or go online right now to book your class. Start to travel now and learn to challenge yourself.A.You should do it continuously.B.But don’t stop on the first try!C.Go outside and do exercise regularly.D.We all need some normal stress in our lives, after all.E.Travel and allow yourself to be interested in new people.F.Some examples might be cooking, sewing, painting and so on.G.A simple 9-minute run around your neighborhood can do wonders for yourself.二、完形填空It was about 5 am on Saturday when Amanda Tanner and her husband were suddenlyside.

贵州省2014届高考英语模拟试题(六)

贵州省2014届高考英语模拟试题(六)第Ⅰ卷第一部分:阅读理解(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,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。

AHaving parked near the car wash beside the supermarket, I came away to wait for my wife to come from work. Coming my way from across the parking lot was what society would consider a bum (流浪汉). From the looks of him, he had no car, no home, no clean clothes, and no money. There are times when you feel generous but there are other times that you just don’t want to be bothered (打扰). This was one of those “don’t want to be bothered times.”“I hope he doesn’t ask me for any money,” I thought. He didn’t. He came and sat on the seat by the bus stop but he didn’t look like he could have enough money to even ride the bus. After a few minutes he spoke, “That’s a very pretty car”. He was ragged (衣着破旧的) but he had an air of dignity (尊严) around him. I said, “thanks,” without taking a look at him.He sat there quietly for a moment. The expected begging for money never came. As the silence between us widened something inside said, “Ask him if he needs any help.” I was sure that he would say “yes”. So I asked, “Do you need any help?”He answered in three simple words that I shall never forget. The three words shook me. “Don’t we all?” he said.I was feeling successful and important, above a bum in the street, until those three words hit me. Don’t we all? I needed help. Maybe not for bus fare or a place to sleep, but I needed help. I reached in my wallet and gave him not only enough for bus fare, but enough to get a warm meal and shelter for the day. Those three little words still ring true. No matter how much you have, you need help too. However, no matter how little you have, you can give help too.1. The author walked away from the car wash to _____.A. go to workB. wash his carC. go shoppingD. meet his wife2. When the author first saw the bum, he planned to _____.A. ignore his difficultyB. give him a lessonC. offer him some helpD. make friends with him3. When the bum said “Don’t we all?”, the author felt _____.A. satisfiedB. shyC. sadD. shocked4. What is the best title for the text?A. The clever bumB. Never lose your dignityC. Don’t we all need help?D. To give or not?BIt would be hard to argue that there is anyone more powerful in Hollywood today than Steven Spielberg. Since his first major success “Jaws” in 1975, he has made one hit movie after another. These include the wildly popular series “Indiana Jones,” “Jaws” and “ET”.Those films are fun and lighthearted. But Steven Spielberg has also made serious films that were well received by critics (评论家) and movie audiences alike. The movie “Saving Private Ryan” is a good example. It is an American war movie in the traditional sense. But, the director’s close attention to detail and historical facts also increased public interest in America’s efforts during World War Two.The film “Schindler’s List” also takes place during World War Two. It tells the powerful story of a German businessman who worked to save Jews from Nazi Germany.Steven Spielberg was born in the city of Cincinnati, Ohio in 1946. His mother owned a restaurant and was also a musician. His father was an electrical engineer. Steven started making movies while he was growing up. He required his family and friends to pay twenty-five cents to see his films when they were completed. Steven Spielberg said this experience led him to produce the film “Super Eight”. It tells about a group of teenagers who join together to make a movie and uncover a mystery in the process.Steven Spielberg is one of the top directors in the film industry and also has many fans in China. When asked about the secret of his success, Steven Spielberg said that he owes much of his success and happiness to his wife and children. He met Cate Capshaw, who is an actress, when he was working on one of his films. After that it still took seven years before they finally got married. The couple has seven children in all.5. What can we learn about the film “Jaws”?A. It failed to attract public interest.B. It was regarded as a serious film.C. It was made after “Indiana Jones”.D. It was made by Steven Spielberg at 29.6. What’s the similarity between “Saving Private Ryan” and “Schindler’s List”?A. They are both humorous.B. They were released at the same time.C. They both happen during World War Two.D. They are both traditional American movies.7. According to the text, Steven Spielberg _____.A. lived a poor life when he was youngB. believed hard work led to his successC. has got seven children in totalD. had musical parents8. The underlined words “this experience” in Paragraph 4 refer to the experience of _____.A. young Steven Spielberg’s lifeB. young Steven Spielberg’s making filmsC. Steven Spielberg’s achieving successD. Steven Spielberg’s living with his familyC“I’d like to be at a healthier weight,” a friend told me. “But we just don’t have the money to buy expensive diet foods and there isn’t enough money to join a gym.” Many people feel that way —that a healthy diet and exercise plan is out of reach because o f their high cost. Don’t lose hope! We’ll be looking at ways to make healthy choices without spending too much money.First you don’t need to buy the expensive pre-prepared “diet foods.” Back in the early 1970s when I started housekeeping, 90% of the food I bought was ingredients. Very few things were preprocessed (预处理的). Now 90% of the food you find in the store is quick food. That’s a bad thing.Quick foods like boxed “just add hamburger” meals have had the fiber (纤维) removed to make them faster to prepare. Take a look at the label (标签) on that box. It often has low numbers listed under “fiber” because fiber takes longer to digest. If the low fiber meal is digested, the result is that your body begins to store fat. Besides, your body is short of nutrients (营养物质). You will be driven to eat more to try to make up for the low quality of the food you are eating.And then there are the chemicals the producers add to the quick meals to make them palatable. If not, the stuff would taste like cardboard and you wo uldn’t enjoy it. However, these chemicals certainly aren’t good for your health.What’s the answer? Buy whole ingredients and give up the expensive, low nutrition, processed foods. Do the cooking yourself and you will have control overwhat is in your food — and it will cost less, too.9. People who find it hard to get a healthier weight think _____.A. they had too much diet foodB. they didn’t make a detailed planC. they have no time to do exercise in gymD. they can’t afford diet food and to exercise in gym10. The author doesn’t like quick food mainly because _____.A. it contains too much fatB. it makes people eat moreC. it has low fiberD. it takes longer to digest11. The underlined word “palatable” in Paragraph 4 means _____.A. freshB. deliciousC. healthyD. poor12. The author suggests in the text that people should _____.A. control the amount of foodB. eat more processed foodsC. cook food for themselvesD. choose cheap ingredientsDWhen it comes to the reason why those people are fond of the foods and other products (产品) of Fresh Choice, I’m willing to share with you some information about that. Here I would like to show you a way to inspect its wonderful stories. So far, it has become popular among the public and has won great fame within a short period of time. Lots of people are crazy about this special restaurant and like to have a try.Compared with other famous companies that provide foods, it has enjoyed a quite short history, as it was created in 1986. However, it has some important characteristics that have led to its success.First of all, most people are familiar with its natural farm produce. It’s good for environmental protection and balanced diets. In addition, Fresh Choice provides customers with all kinds of foods, including soups, desserts and all kinds of salads, along with many other delicious dishes. The most important thing is that all these foods contain enough nutrition, such as protein, vitamins and fiber. At the same time, they keep customers away from too much fat, carbohydrates (碳水化合物) and calories, which helps them keep a balanced diet and lifestyle. More often than not, many people suffer the serious problem of being overweight, especially in western countries. It is important for them to lose weight and improve their confidence. And Fresh Choice is just the right choice for them and saves them from this seriousproblem. What is more, customers can get a good discount with more visits. With the powerful sup-port of some promotional (促销的) activities, more and more people have developed a good impression of Fresh Choice and share their pleasant experience with close friends and family.13. People are crazy about Fresh Choice mainly because _____.A. it enjoys great fameB. it has a long historyC. it offers healthy foodD. it provides cheap but tasty food14. Which of the following is TRUE according to the text?A. Most westerners are satisfied with their weight.B. Fresh Choice has never held any promotional activities.C. Most people don’t know about natural farm produce.D. Natural farm produce is good for a balanced diet.15. The purpose of the text is mainly to tell readers _____.A. how to manage a restaurantB. what we can enjoy in Fresh ChoiceC. the importance of keeping a balanced dietD. the reasons why Fresh Choice has become popular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。

一、现代文阅读(35分)(一)现代文阅读Ⅰ(本题共5小题,18分)阅读下面的文字,完成1~5题。

材料一:“美”是什么?不同的人有不同见解,其实美一直都存在我们生活中的各个地方,而与我们朝夕相处的建筑则是对美最好的诠释。

但是,在不同的区域,不同的民族以及不同的时代对建筑之美则有不同的看法与总结。

建筑作为文化的重要组成部分,它如实地记载了人类文明发展的脚步,具有鲜明的时代特点和民族特色。

传统的西方建筑长期以石头为主体;而传统的东方建筑则一直是以木头为构架。

不同的建筑材料,使得中西方的古代建筑有了不同的艺术表现。

另外,与西方的石制建筑不同,中国传统造型特别强调“线型美”,讲究线条的婉转流动,从而构造出多种多样的飞檐。

可以说飞檐的设计是我国古典建筑中的璀璨明珠。

不同的飞檐形式往往会有不同的艺术效果,或轻灵,或朴实,或威严。

我国古典建筑的四大家——亭、台、楼、阁都用飞檐来标明自己的身份,表达自己的情感,而且飞檐的高低、长短往往会成为建筑设计的难点和要点。

而西方建筑则一般是垂直发展,建得又高又大,譬如罗马可里西姆大斗兽场高为48米,“万神殿”高43.5米,中世纪的圣索菲亚大教堂,其中央大厅穹窿顶离地达60米。

文艺复兴建筑中最辉煌的作品圣彼得大教堂,高137米。

它们以夸张的造型和撼人的尺度展示建筑的永恒与崇高,以体现人之伟力。

中国传统建筑最具有代表性的便是古典园林建筑,因深受儒家思想的影响,文人的追求和喜好左右着造园,因而中国的传统园林在实际意义上是文人园林,历来讲究“气韵生动”的美学原则,在本体认识的差异上,重视整体的和谐。

ALondon’s Millennium Dome closed its doors on Sunday evening. In the past year people argued about the public funds spent on it and about the low attendance.The huge tent-like structure at Greenwich on the south bank of the Thames River was run by the New Millennium Experience Company (NMEC). The company allowed only 27,000 people to enter on the final day, after 37,000 visited it on Saturday.The total attendance for the year was around 6.5 million. The lowest monthly attendance was in January when only 366,420 visited the Dome.A single ticket to the Dome cost 20 pounds (US$30). But the attendance figure included thousands of children on free school visits. Others took advantage of a special 57 pounds for five people offer.Many traveled to London especially to seize their last chance to see the Body Zone. Body Zone is a collection of blue diamonds with the huge Millennium Star at its center.The Japanese bank Nomura was to have taken over the structure to run it as a leisure venture. But it withdrew last October because of lack of financial data.Among visitors on the last day, were Prime Minister Tony Blair’s wife Cherie and three of their children, Euan, 16, Nicky, 15, and Kathryn, 12.2. According to the article, a specialticket price offer was .A. a group of one thousand school children can be admitted for freeB. 57 pounds for five peopleC. US $ 30 eachD. 20 pounds each3. Japanese bank Nomura gave up bidding for the structure last Octoberbecause .A. there was not enough financial dataB. the New Millennium Experience Company was competing with itC. there was public argument about the DomeD. the Japanese bank Nomura was to run it as a leisure venture4.Tony Blair’s wife Cherie visited the Dome on .A. FridayB. SaturdayC. SundayD. MondayBLet’s pretend we’re sailing down the Rhine River on a pleasure boat. The Rhine is one of the main waterways of Germany, and the river traffic is heavy. It’s interesting to watch many boats going up and down the river. But the river traffic is not nearly so interesting as the beautiful scenery along the banks and hillsides. Theboat is passing many old castles. We can see people working in the vineyards(葡萄园)on the hillsides. There are vineyards as far as the eye can see. Wine from the Rhine Valley is famous all over the world.Suddenly our boat slows down and begins to turn a little. We are coming to a sharp bend in the river. On our right we can see a rocky cliff over 400 feet high. At first it looks quite ordinary, but there is nothing ordinary about it. There are many stories, poems, and songs about the cliff. We are looking at the Lorelei.Then someone on the boat begins to sing in German, the song of the Lorelei. It is a song about a beautiful siren(美女)who has lured many sailors to their deaths.The siren is supposed to sit on the rock combing her long golden hair and singing. The sailors who hear her song forget to steer, and the current of river hurls their boats on the rocks and dashes them to pieces.Soon other people on the boat begin to sing. The beautiful song adds to special magic to the moment, and you begin to realize why so many people have made this trip down the Rhine to see the rock of the Lorelei.5. The more interesting thing to those who are sailing down the Rhine River on apleasure boat is .A. to watch many boats going up and down the riverB. to see the beautiful scene along the banks and hillsidesC. to hear a song about beautiful sirenD. to see a beautiful siren combing her golden hair6. Which of the following is famous all over the world?A. The Rhine River.B. The River Traffic.C. Wine from the Rhine Valley.D. The Lorelei.7. We can see a rocky cliff over 400 feet high .A. on our right when coming to a sharp bendB. on the Rhine hillsidesC. from the Rhine ValleyD. on the boat8. The song of the Lorelei is about .A. the Rhine wineB. a rocky cliffC. the beautiful scenery along the Rhine RiverD. a beautiful and dangerous beautyCHappy April Fool’s DayIn celebration of the day, we have put together a list of some of the greatest hoaxes in history .They are the lies that have been designed for innocent people who are ready to believe them.INSTANT COLOR TVIn 1962 there was only one TV channel in Sweden, and in broadcast in black and white. The station’s technical expert, Kjell Stensson , appeared on the news to announce that thanks to a newly developed technology, all viewers could now quickly and easily transform their existing sets to display color reception. All they had to do was pull a nylon stocking over their TV screen, and they would begin to see their favorite shows in color. Reportedly, hundreds of thousands of people were taken in. Actual color TV transmission only started to appear in Sweden on April 1, 1970.SAN SERRIFFEIn 1977 the British newspaper The Guardian published a special seven-page supplement(增刊)in honor of the tenth anniversary of San Serriffe, a small republic located in the Indian Ocean. A series of articles affectionately described the geography and culture of this unknown nation. The Guardian’s phones rang all day as readers asked for more information about the beautiful holiday spot. Few noticed that everything about the island was made up.NIXON FOR PRESIDENTIn 1992 American National Public Radio’s Talk of the Nation program announced that Richard Nichard Nixon, in a surprise move, was running for President again. His new campaign slogan was, “I didn’t do anything wrong, and I won’t do it again.”Accompanying this announcement were audio clips(片断)of Nixon delivering his election speech.
