2019-2020学年山西大学附属中学高三英语三模试卷及参考答案
2019-2020学年山西大学附属中学高三英语三模试卷及参考答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AIn his 402nd anniversary year, Shakespeare is still rightly celebrated as a great language master and writer. But he was not the only great master of play writing to die in 1616, and he is certainly not the only writer to have left a lasting influence on theater.While less known worldwide, Tang Xianzu is considered one of Chinas greatest playwrights and is highly spoken of in that country of ancient literary and dramatic traditions.Tang was born in 1550 inLinchuan,Jiangxiprovince. Unlike Shakespeare's large body of plays,poems and sonnets (十四行诗), Tang wrote only four major plays: The Purple Hairpin, Peony Pavilion (《牡丹亭》), A Dream under the Southern bough, and Dream of Handan. The latter three were constructed around a dream narrative, a way through which Tang unlocked the emotional dimension of human desires and ambitions and explored human nature beyond the social and political limits of that time.Similar to Shakespeare, Tang's success rode the wave of a renaissance (复兴) in theater as an artistic practice. As in Shakespeare'sEngland, Tang's works became hugely popular inChinatoo. During Tang'sChina, his plays were enjoyed performed, and changed. Kunqu Opera, a form of musical drama, spread from southernChinato the whole nation and became a symbol of Chinese culture. Combining northern tune and southern music, kunqu Opera was known for its poetic language, music, dance movements and gestures. Tang's works benefited greatly from the popularity of kunqu Opera, and his plays are considered classics of kunqu Opera.While Tang and Shakespeare lived in a world away from each other, there are many things they share in common, such e humanity of their drama, their heroic figures, their love for poetic language, a lasting popularity and the anniversary during which we still celebrate them.1. Why is Shakespeare mentioned in the first paragraph?A. To describe Shakespeare's anniversary.B. To introduce the existence of Tang Xianzu.C. To explain the importance of Shakespeare.D. To suggest the less popularity of Tang Xianzu.2. What's possibly one of the main theme of Tang's works?A. Social reality.B. Female dreams.C. Human emotions.D. Political environment.3. What does the author mainly tell us in Paragraph 4?A. The influence of Kunqu Opera on Tang's works.B. Tang's success in copying Shakespeare's styles.C. The way Kunqu Opera became a symbol of Chinese culture.D. Tang's popularity for his poetic language and music.BImust have always known reading was very important because the first memories I have as a child deal with books. There was not one night that I don’t remember mom reading me a storybook by my bedside. I was extremely inspired by the wonderful way the words sounded.I always wanted to know what my mom was reading. Hearing mom say, “I can’t believe what’s printed in the newspaper this morning,” made me want to grab it out of her hands and read it myself. I wanted to be like my mom and know all of the things she knew. So I carried around a book, and each night, just to be like her, I would pretend to be reading.This is how everyone learned to read. We would start off with sentences, then paragraphs, and then stories. It seemed an unending journey, but even as a six-year-old girl I realized that knowing how to read could open many doors. When mom said, “The C-A-N-D-Y is hidden on the top shelf,” I knew where the candy was. My progress in reading raised my curiosity, and I wanted to know everything. I often found myself telling my mom to drive more slowly, so that I could read all of the road signs we passed.Most of my reading through primary, middle and high school was factual reading. I read for knowledge, and to make A’s on my tests. Sometimes, I would read a novel that was assigned, but I didn’t enjoy this type of reading.I liked facts, things that are concrete. I thought anything abstract left too much room for argument.Now that I’m growing and the world I once knew as being so simple is becoming more complex, I find myself needing a way to escape. By opening a novel, I can leave behind my burdens and enter into a wonderful and mysterious world where I am now a new character. In these worlds I can become anyone. I don’t have to write down what happened or what technique the author was using when he or she wrote this. I just read to relax.We’re taught to read because it’s necessary for much of human understanding. Reading is an important part of my life. Reading satisfies my desire to keep learning. And I’ve found that the possibilities that lie within books are limitless.4. Why did the author want to grab the newspaper out of mom’s hands？A. She wanted mom to read the news to her.B. She couldn’t wait to tear the newspaper apart.C. She couldn’t help but stopmom from reading.D. She was eager to know what had happened.5. According to Paragraph 3, the author’s reading of road signs shows___________.A. her own way to find herselfB. her eagerness to develop her reading abilityC. her growing desire to know the world around herD. her effort to remind mom to obey traffic rules6. The author takes novel reading as a way to___________.A. explore a mysterious landB. develop an interest in learningC. get away from a confusing worldD. learn about the adult world7. What could be the best title for the passage？A The Pleasure of Reading B. Growing Up with ReadingC. The Magic of ReadingD. Reading Makes a Full ManCIn Copenhagen, an 8-year dream was realized when the first paid skiers took their runs down a one-third-mile course (路线)．They skied on what is possibly the greenestpower factory in the world．The factory is so clean and safe that designers were able to turn its buildings into a new center for social life．The waste-to-power factory itself opened in 2017 under the name Amager Bakke．Bjarke Ingels is the architect whosecompany came up with the idea eight years ago of designing a power plant building that would join mountain sports into its very nature．“It is the cleanest waste-to-energy power plant in the world．It is not only better for the environment, it is also moreenjoyable for the lives of its citizens.” Ingels says 97% of city people get their heating as a by-product of energy production．It comes from a system where the electricity, heating, and waste disposal (处理) are mixed into a single process．He dreams that it is also becoming an example that others can look to and say, “IfCopenhagencan do it why can' t we?"There are no hills in this island city, but now people can ski locally, while enjoying the best views ever seen of the harbor．Another thing missing hereis snow cover throughout the winter, so designers set up a kind of special "plastic grass" that provides the perfect friction (摩擦力) for downhill winter sports．In a country where 600, 000 skiers always had to travel to practice sking, to be able to finally ski in their backyard-and, all year round - is, as one skier said, “AMAZING．”The company hopes to see 300, 000 visitors enjoying the experience of Copen hill each year, with the ski slope costing $ 22 an hour or just $ 366 for a full season pass．Meanwhile, the city is one step closer to its final goal of becoming the world's first carbon-neutral city by 2025．We thinkit might be all “down hill” from here．8. How does the power factory produce electricity?A. By using oil．B. By using coal．C. By usingwind．D. By using waste．9. What' s Ingels' dream according to the passage?A. To make more tall buildings in different big cities．B. To help more skiers to ski in high mountains．C. There will be more green power factories in the world．D. More and more people will ski in the power factory．10. Where do the skiers ski in the power factory?A. On man-made snow．B. On man-made ice．C. On plastic grass．D. On real sand．11. The underlined part “it might be all 'downhill' from here" means that________.A. they will soon reach their final goalB. they will soon draw many visitorsC. they will produce more electricityD. they have difficulties reaching the goalDBritish anthropologists (人类学家) Russell Hill and Robert Barton of the University of Durham, after studying the results of one-on-one boxing, tae kwon do, Greco-Roman wrestling and freestyle wrestling matches at the Olympic Games, conclude that when two competitors are equally matched in fitness and skill, the athlete wearing red is more likely to win.Hill and Barton report that when one competitor is much better than the other, colour has no effect on the result. However, when there is only a small difference between them, the effect of colour is enoughtipthe balance.The anthropologists say that the number of times red wins is not simply by chance, but that these results are statistically significant.Joanna Setchell, a primate (灵长目动物) researcher at the University of Cambridge, has found similar results in nature. She studies the large African monkeys known as mandrills. Mandrills have bright red noses that stand out against their white faces. Setchell’s work shows that the powerful males — the ones who are more successful with females — have a brighter red nose than other males.As well as the studies on primates by Setchell, another study shows the effect of red among birds. In an experiment, scientists put red plastic rings on the legs of male zebra finches and this increased the birds’ success with female zebra finches, Zebra finches already have bright red beaks (鸟喙), so this study suggests that, as with Olympic athletes, an extra flash of red is significant. In fact, researchers from theUniversityofGlasgowsay that the birds’ brightly coloured beaks are an indicator of health. Jonathan Blount, a biologist, andhis colleagues think they have found proof that bright red or orange beaks attract females because they mean that the males are healthier. Nothing in nature is simple, however, because in species such as the blue footed booby, a completely different colour seems to give the male birds the same advantage with females.Meanwhile, what about those athletes who win in their events while wearing red? Do their clothes give them an unintentional advantage? Robert Barton accepts that “that is the implication” of their findings. Is it time for sports authorities to consider new regulations on sports clothing?12. According to their research. Hill and Barton conclude that ________.A. the colour of clothing has an effect on most sport eventsB. red should be the choice of colour for clothing in sportsC. red plays a role when competitors are equally capableD. athletes perform better when surrounded by bright red13. The underlined word “tip” in Paragraph 2 is closest in meaning to ________.A. achieveB. advanceC. keepD. change14. The example of the blue footed booby proves that ________.A. male birds use different body parts to draw attentionB. red is not the only colour to attract female birdsC. blue gives female birds the same advantageD. blue can indicate how healthy a bird is15. What can be inferred from the passage?A. The colour red gives male animals the most advantage.B. Male zebra finches prefer to have red plastic rings on their legs.C. Rules on sports clothing are going to be changed.D. Athletes wearing red may have an advantage over their opponents.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

2020年山西大学附属中学高三英语三模试题及参考答案
2020年山西大学附属中学高三英语三模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AThe history ofpop art begins with abstract art. Pop art emerged from the foundation of abstract art in the 1950s, first gaining recognition in Great Britain, then establishing itself in the United States in the 1960s.In the 1930s and 1940s, abstract art was greatly popular, but people began to hate this art form. Most abstract art produced in this era could be found in art galleries or the homes of the elite(名流), not in the homes of everyday people. Pop art sprung onto the scene as the people's art.Some art critics say pop art is a rebellion against abstract art; others say it is an extension of abstract art. You can see elements of abstract art in many pop art prints, especially those that consist of a collage（拼贴画）of images. However, some pop art pieces have nothing to do with abstract art, looking more like a photo of a popular consumer item, which impressed people deeply.Richard Hamilton and Eduardo Paolozzi were two of the first contemporary pop art pioneers recognised in Great Britain. They were a part of the Independent Group, an organised group of British artists who wanted to challenge ruling modernist approaches to culture. They recognised the value of modern advertising and comic book images. They used these popular images in art as a social commentary, often building irony and humour into their artworks, thus creating a new form of art. These pieces were mass-produced and sold at affordable prices.When pop art took off in the United States, it expanded to include a celebration of kitsch and the common images found in movies and television. Andy Wharhol is perhaps the most famous American pop art artist, known for his prints of the actress Marilyn Monroe, the singer Elvis Presley and of Campbell's soup cans. Andy Wharhol was inspired by images from advertisements and common consumer items. He also made a series of paintings which showed images of car accidents.1. Why did people dislike abstract art?A. People found it hard to understand.B. Ordinary people couldn't afford it.C. People disliked enjoying it in galleries.D. It wasn't based on everyday life.2. What impression do pop art works leave on people?A. They are a rebellion against abstract art.B. They have many elements of abstract art.C. They are created so real.D. They are products of advertisers.3. The Independent Group was set up to ________.A. introduce a new art form to the worldB. develop modern advertising furtherC. create new comic book imagesD. make British culture better knownBDoctors are known to be terrible pilots. They don’t listen because they already know it all, I was lucky: I became a pilot in 1970, almost ten years before I graduated from medical school. I didn’t realize then, but becoming a pilot makes me a better surgeon. I loved flying. As 1 flew bigger, faster planes, and in worse weather, I learned about crew resource management (机组资源管理), or CRM, a new idea to make flying safer. It means that crew members should listen and speak up for a good result, regardless of positions.I first read about CRM in 1980. Not long after that, an attending doctor and I were flying in bad weather. The controller had us turn too late to get our landing ready. The attending doctor was flying; I was safety pilot. He was so busy because of the bad turn, he had forgotten to put the landing gear (起落架) down. He was a better pilot—and my boss—so it felt unusual to speak up. But I had to: Our lives were in danger. I put aside my uneasiness sand said, we need to put the landing gear down now! That was my first real lesson in the power of CRM, and I’ve used it in the operating room ever since.CRM requires that the pilot/surgeon encourage others to speak up. It further requires that when opinions are from the opposite, the doctor doesn’t overreact, which might prevent fellow doctors from voicing opinions again. So when I’m in the operating room, I ask for ideas and help from others. Sometimes they’re not willing to speak up. But I hope that if I continue to encourage them, someday someone will keep me from landing gear up.4. What does the author say about doctors in general?A. They like flying by themselves.B. They are quick learners of CRM.C. They pretend to be good pilots.D. They are unwilling to take advice.5. The author deepened his understanding of the power of CRM when .A. his boss landed the plane too lateB. he was in charge of a flying taskC. he saved the plane by speaking upD. his boss operated on a patient6. In the last paragraph landing gear up probably means .A. following flying requirementsB. making a mistake that may cost livesC. listening to what fellow doctors sayD. overreacting to different opinions7. Which of the following can be the best title for the text?A. CRM: A New Way to Make Flying SafeB. A Pilot-Turned DoctorC. The Making of a Good PilotD. Flying Makes Me a Better DoctorCAn afternoon nap(午睡)is one of the joys of life, although too much napping could signal all is not well. In some cultures, people will have a daily nap — thisis fine. The warning comes when people start sleeping during the daytime, when they did not before. There is certainly a good reason to believe that daytime sleepiness — as in the Alzheimer's study — can be a marker of an underlying condition.For most people, napping during the day is mainly a sign that you are not getting enough sleep at night, says Dr. Neil Stanley, a sleep expert. "If you feel sleepy during the day, you should think about taking a nap. That is what the body needs — it doesn't need to be kept awake with caffeine, it needs sleep. "The feeling to notice is "sleepiness", he says, not "tiredness", which could be more psychological and linked to stress.So how do you nap well? The key thing, says Stanley, is how long your nap lasts. Choose either a 20-or 90-minute nap. "When you fall asleep, you'll quickly go through the lighter stages of sleep into your first period of deep sleep. You don't want to wake up in deep sleep because that's when you wake and feel worse than you did before. "Napping for 20 minutes means you will wake up before you go into deep sleep; napping for 90 minutes means you'll complete a sleep cycle.Once you factor in the time it takes to fall asleep — some people are better at napping than others but, says Stanley, "a healthy adult will fall asleep in between 5 and 12 minutes" — you can set an alarm, allowing a 30- to 40-minute period for a short nap, and up to two hours for a longer one.A good time to nap is during the body's natural dip in the afternoon, between 2 pm and 4 pm. "You don't really want to be napping much pastthatbecause then you are going to be eating into your night-time sleep," Stanley says. The point, he stresses, is to get good night-time sleep, which would ensure you probably don't need to nap at all.8. What does an afternoon nap indicate for most people?A. Caffeine addiction.B. Psychological stress.C. Insufficient night sleep.D. Potential physical illness.9. What is the key to a good nap?A. Duration.B. Surroundings.C. Health.D. Stages.10. What does the underlined word "that" in the last paragraph refer to?A. A 30- to 40- minute period.B. Between 2 pm and 4 pm.C. Between 5 and 12 minutes.D. A 20- to 90-minute period.11. Which of the following can be the best title for the text?A. Why to phase a napB. When to take a good napC. What to learn from a napD. How to have a successful napDIs homeschooling good or bad? That is a question that many parents ask themselves. In my opinion, homeschooled kids can give reliable answers.Kayla Murray, who lives inGreensboroNorth Carolina, started homeschooling almost eight years ago, after attending two local schools. “Homeschooling is school at home,” like the name says, but it’s not just that/ she says. “You're able to learn more and do more.”Having experienced learning at both school and home, Kayla says that she prefers the latter. “With homeschooling, I can do schoolwork in my pajamas, and no one cares,” she says, “you also have more chances. Earlier this year, my family and I were able to take a short vacation and go to an air show. My siblings and I get to take the day off for our birthdays. This year, I spent that time reading and playing the piano and guitar.”There are, however,drawbacksof being homeschooled, Kayla says, especially “the lack of people”. While she doesn't miss homework, al school, she did enjoy getting to see my friends every day.”Matthew Dimmette, also fromGreensboro, used to be a homeschooler. He now attends public high school. He says being homeschooled is quite different from going to public school. The differences depend on how you arc homeschooled and the things you do. “For me, it wasn't really different in terms of the classes but the school environment was a big change atter hearting at home. says Matthew.Talking about his homeschooling experience, Matthew says the best part of it was being able to learn what he wanted to. Yet the main disadvantage was that he couldn't do many experiments in homeschooling unless taking classes at different places. “My interest in science has been growing quickly in recent years, so I chose to goto public school,” he says.12. What does Kayla like about learning at home?A. She can spend her time more freely.B. She can always stay with her siblings.C. She can play the instruments she likes.D. She can celebrate her birthday at home.13. What does the underlined word “drawbacks” in Paragraph 4 probably mean?A. Concerns.B. Reasons.C. Changes.D. Problem.14. Why did Matthew choose to go to public school?A. He wanted to make more friends.B. He wanted to do experiments in labs.C. He wanted to take all kinds of classesD.He wanted to experience the school environment15. What in the authors attitude cowards homeschooling?A. Supportive.B. Doubtful.C. Uninterested.D. Unclear.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

The two World Wars are examples. Sometimes nature even becomes part of history. Shaking earthquakes are recorded in history books.Sixteen years ago, nature caused just such a history-making event. In September 2005, Hurricane Katrina came ashore inNew Orleans,Louisiana. The deadly storm floodedNew Orleans. Before Katrina, no other big American city had ever flooded in the history of the country. This natural disaster caused great harm and death.New Orleansis located below sea level. This location places it at great risk. Levees were built to protectNew Orleansfrom the ocean. (A levee is like a wall between the city and the ocean.) When Hurricane Katrina came ashore, water moved over the levees into the city. Flooding made it necessary for everyone to leave the city. Before Katrina, Creole food (a special kind of cooking only inLouisiana) filled the air with delicious smells. The sound of jazz music traveled through the streets. Now the city has to return to its former glory.Before Katrina, ernment had never made everyone leave a city. People inNew Orleanshad to find shelter quickly. Some had to stay at theSuperdomeSportsCenter. Some rode on buses to other towns. Thousands drove their cars to get away from the storm. The roads and shelters filled up fast.The lesson learned from Katrina was that cities must be better prepared for big storms and other terrible disasters caused by nature. Being prepared might have kept more people safe. Hurricane Katrina is one of the history-making events that will be remembered forever. Today, history is still being made that will shape the future.4. What does the author tell us aboutNew Orleans?A. It was built above sea level.B. It had few jazz musicians after Katrina.C.

Try to get ready for natural disasters.7. What is the best title for the text?A. Storms are dangerousB. Katrina makes historyC. Floods shapeLouisianaD. History must be rememberedCAvi Loeb, a scientist, believes that we are not alone in the universe. The belief fits withLoeb's alien spaceship theory that at least one alien spaceship might be flying over the orbit of Jupiter, which won the international attention last year.Astronomers inHawaiifound the first known interstellar object in late 2017. It was a bit of light moving so fast past the sun that it could only have come from another star. Almost every astronomer on the planet was trying to figure out how the object, called “Oumuamua” got to our far-away part of the Milky way galaxy. “One possibility is that ‘Oumuamua’ is debris from an advanced technological equipment,” Loeb said. “Technology comes from another solar system just showed up at our door. ”“‘Oumuamua’ is not an alien spaceship,” Paul Sutter, another scientist wrote. He suggested Loeb was seeking publicity. Most scientists think “Oumuamua” is some sort of rock. They think it could be an icy wandering comet.Loeb says that “Oumuamua's” behavior means it can't be a block of rock shaped like a long photo. He thinks it's more likely an object that's very long and thin, perhaps like a long pancake or a ship's sail. Loeb says that if someone shows him evidence thatcontradictshis beliefs, he will immediately give in.Loeb believes himself a truth-teller and risk-taker in an age of very safe, too-quiet scientists. “The worst thing that can happen to me is that I would be relieved of my management duties, and that would give me even more time to focus on science,” Loeb says. He said he wouldn't mind giving up all the titles he had and returning to theIsraeli farming village where he grew up.8. What does Loeb say about “Oumuamua”?A. It is an icy comet.B. It looks like a long photo.C. It is actually some sort of rock.D. It may come from another alien civilization.9. What does the underlined word “contradicts” in paragraph 4 probably mean?A.Goes against.B. Relies on.C. Turns to.D. Searches for.10. What do you think of Loeb?A. He is foolish.B. He is unsatisfied with his titles.C. He is a firm believer in scientific truth.D. He is uncertain about his career future.11. What's the best title for the text?A. Have Aliens Paid a Visit in Spaceships?B. Do We Really Know about Space Theory?C. Scientists Are Working on High TechnologyD. Astronomers Are Encouraging Space TravelDIt was once a shoreline buried by enough garbage to make it invisible (看不见的), thus, given the unfortunate nickname "toilet bowl" . Now the Philippines' Manila Bay beach is totally different, compared with a few months ago. It happened so suddenly and extremely that it brought tears to the eyes of the local people.The cleanup started on 27 January, when 5, 000 volunteers descended on Manila Bay to remove over 45 tons (公吨) of garbage, marking the beginning of a nation-wide environmental campaign. But some two months before this great movement began, a quiet revolution was already underway.During the first week of December 2018, Brooklyn- based Bounties Network collectedthree tons of garbage from Manila Bay aver two days through a project that paid a small group of people, mostly fishermen, with a digital currency (数字货币) based on the Ethereum system.For the mostly non-bank -using Filipino fishermen, this was a first-ever experience with a digital currency. It's one that proves decisive in enabling poor communities around the world to take up arms in the fight against humanity's waste.There are signs that this recycling-for-digital payment industry may be just about to take off. Earlier in September 2018, Plastic Bank, a Vancouver -based company powered by IBM technology, also started a similar project. They set up a project in Naga, a town in southern Luzon, the country's largest island, building a collection point to let people exchange plastic and recyclable materials for digital payouts through a system.That both these pioneers have chosen the Philippines as their first location is not surprising considering thecountry's contribution to ocean waste. A Wall Street Journal study in 2015 revealed that the Philippines make the third-largest amount of plastic waste into global oceans.12. Why did people call Manila Bay beach“toilet bowl” ?A. It looked like a huge bowl.B. There were plenty of toilets.C. It was covered by rubbish.D. People loved the toilets here.13. What does the underlined phrase“descended on”in paragraph 2 mean?A. Completely depended on.B. Suddenly arrived at.C. Occasionally decreased to.D. Gradually disappeared from.14. What made poor communities willing to fight against waste?A. The benefits to their homeland.B. The desire to make a difference.C. The chance to escape ocean pollution.D. The experience with a digital currency.15. What is the best title for the text?A. Online system helps endocean pollution.B. Manila Bay beach is suddenly removed.C. Plastic Bank is powerful in recycling waste.D. Philippines make a great amount of waste.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

Since last year, Natalie, 15, hasbeen taking lost or thrown — away fishing nets and rope and transforming them into bracelets, rope art, mats, baskets and necklaces.Last year, Natalie was working on an assignment for her science, technology, engineering and mathematics (STEM) class. As part of the assignment, she learned about “ghost nets”, which are fishing nets that have been left or lost in the ocean by people who fish.“They have huge effects on our environment. They can kill coral reefs and many animals,” said Natalie. “46 percent of the Pacific garbage is ghost gear.” The Great Pacific Garbage is a huge collection of trash floating in the Pacific Ocean betweenHawaiiandCalifornia.Natalie told her mom she wanted to do something to help. She got in touch with a handful of charities, including the Sea Protection Society and Coastal Action.After getting some shipments of ghost nets and rope from those organizations, Natalie, with the help of her family, started turning thediscardedgear into new artworks. “We've made bracelets, rope art, mats, baskets, and we've made necklaces, which also use beach glass in them,” she said. Natalie then started selling the artworks online, the crafty buying and selling website.She donated all her profits-minus a small sum of change to cover supplies — to the charities that donated fishing supplies to her. She's also been donating all the income from her non-profit business, called Nautical Waters, to charity. Natalie said she hoped to continue her passion for ocean life, with plans to study marine biology in university.4. How did Natalie help with ghost nets?A. By turning them into artworks.B. By asking support from her mother.C. By collecting money from charities.D. By selling ghost nets at a good price.5. What made Natalie decide to do something with ghost nets?A.

Charities Make a Big DifferenceC. Natalie's Passion for Ocean TreasuresD. TeenTurnsOld Fishing Nets into ArtworksC"Sorry, but I don't agree with you..."This is usually followed by unbearable silence and angry tears. I've always found it difficult to disagree with someone, because I don't want to lose a friend. I've found it even harder to accept it when someone disagrees with me, because my ego（自尊心）ishurt.Before the other person gets a chance to explain why she disagrees with me, my usual response would be," If you aren't able to see my point of view, then what you think isn't worth my time or consideration, either." But now I've come to realize that when a friend disagrees with me, sometimes she is simply saying, "I don't agree with the way things are done." She still respects me as a person, and is only pointing out a better way to look at a matter. However, there may be times when my friend disagrees with me because I'm against the truth. That's when need to listen to what she says.I've learned that one way to help my friend is for me to be open and honest with the other to voice my thoughts and listen to the other carefully. While we can't control how a person will respond to our views, we must learn to disagree with our friends in love. We will never feel that we are better than the other person.And that will help us to be less emotional, and more objective in the way we express our opinions.In the same way, we can also stay open to feedback（反馈）from others,knowing that our friends may be correcting us in love.Good friendships build each other up, sometimes through disagreements and honest opinions. Though I don't like being disagreed with, I'm starting to see the value of such disagreements.8.

Half of these adults said they are most often motivated to clean when they're happy. In fact, 63% of those surveyed find the experience of cleaning to be relaxing - even more so than getting fresh air (61%).But that's not the only reason people clean. A big 70% admitted that tidying their home was a way of putting off having to do other things, with the average procrastinator (拖延者) using that trick four times a week. The survey showed that 86% of respondents do feel on top of their housework, but the last deep clean of their kitchen happened over a week and a half ago. That's no surprise because the kitchen is most terrible of all.Conducted by OnePoll on behalf of DishFish, the survey investigated people's attitudes toward dirty dishes and how they get through tricky task. More than two-thirds of people (69%) let their dishes pile up between washings with 20% saying “always” letting them be placed in the sink, which left them feeling stressed. More than any other room, the kitchen was rated as “very difficult” to cope with. And most people enjoy cleaning their toilet or taking out the garbage more than washing dishes by hand.How do they get through it? 66% listen to music while they clean. 72% have a best-loved song that they sounded while tidying up their home, with “Uptown Funk,”“Read All About It” and “Work” being the three favorite tunes on America's cleaning playlist.12.

2021届山西大学附属中学高三语文第三次联考试题及答案一、现代文阅读（36分）(一)现代文阅读I(9分)阅读下面的文字，完成下面小题。
别茶①刘帆钱之江从小就想去看茶。
有一年，香江天气闷热，罗湖桥一带却异常热闹。
听说部队就要从鹏城移防过罗湖桥了，钱之江的心提了起来。
爷爷说四十八年前，也有一支部队过江，粗布军衣，打着背包，在南京路上枕着马路沿睡了一宿，有起得早的富商巨贾，推门一看，都大吃一惊！钱之江的爷爷在他小时候一再讲这个故事，还说一辈子都没有见过这么仁义的部队。
钱之江印象深刻。
爷爷从来没有这么眉飞色舞过。
钱江纱厂公私合营后，爷爷沪港两头跑，后来常驻港岛，生意继续，家里时常来人，讲的话与岛上的人不一样。
钱之江就觉得，说话的人，讲国语，他们说的江南水乡，钱之江没去过，倒是课本上白乐天的诗“江南好，风景旧曾谙。
日出江花红胜火，春来江水绿如蓝，能不忆江南？”钱之江至今记得。
爷爷说，江南塞北，青山依旧在，几度夕阳红。
有机会你可以去看看。
去看看江南塞北，这是钱之江一直的梦想。
人们说，去看江南塞北，要过桥，过罗湖桥。
钱之江好想去。
刚开始年龄小，去不了；等长大了，又念书，仍去不了；再大一点儿，去了英国，还是去不了。
钱之江就想，等我能够经济独立的时候，就自己去。
爷爷说过，江南的水，江南的茶，你带一点儿回到香江。
钱之江终于来了，问茶，看茶。
下榻的酒店在春江路，虽然距离香江不过一百七十多里，但是自从爷爷腿脚不方便后，又是十年光景。
钱之江下榻的房间里有一张太师椅，斜卧在那里，似乎在诉说着什么。
钱之江离开洁白的床，踱步到落地窗前，远处高楼林立，阳光恰到好处地倾泻在楼宇和树叶上，此刻，他只想静静地待一会儿。
他俯瞰城市，蓦然发现，一缕香气氤氲。
茶几上，一杯清茶香气袅袅。
钱之江回头，知道茶是碧螺春，产于太湖边的吴县，爷爷生于斯。
多年来，受爷爷影响，他对这款茶也是情有独钟。
“洞庭无处不飞翠，碧螺春香万里醉”钱之江侧过身子，单手倚在窗前，目光灼灼，仿佛入定一般站在那里。

I am Christopher Intagliata.The Apollo missions brought back 842 pounds of rock and soil from the moon, that's nearly 2200 different samples. But the most interesting one, according to a scientist Meenakshi Wadhwa, is a sample named "Apollo 1-0-0-8-5collected by Neil Armstrong on Apollo 11.“He was about to step back into the lunar module(登月舱) when he turned around and saw there were little spaces in the rock box. He knew that geologists on earth would be just so excited to study these materials, so he just scooped up nine scoops(勺) of soil and put it into the box." Wadhwa explained.It was one of the most well studied samples of the Apollo missions. And a geologist named John Wood noticed white flecks(微粒) of rock in the soil, which inspired him to dig deeper into the moon's ancient past.“This was quite a leap of imagination — he proposed that the whole of the moon had been almost covered with a magma(岩浆) ocean nearly 4.5 billion years ago. This was a revolutionary idea at the time, because people had thought the moon had formed cold, so it completely changed our idea how the moon formed.”But Wadhwa has a more personal reason to appreciate this sample. She met her husband Scott Parazynski also because of this rock sample. Scott, a mountaineer at that time, wanted to climbMount Everestwith a moon rock while Wadhwa was the chairman of the NASA committee that gives access to the samples for scientific purposes.Neil Armstrong's last-minute scoop of moon dust brought two people together here on Earth and upturned our understanding of how the moon — and the Earth itself-got here.Thank you for listening for Scientific American's 60-Second Science.4. It can be learned from Paragraph 3 that ________ .A. Neil Armstrong was excited to find the soilB. the spaceship was about to land on the moonC.

What is the text mainly about?A. A romantic story of a moon rock.B. A big leap made by Neil Armstrong.C. An unusual task for Apollo missions.D. An unexpected discovery in moon exploration.CA growing body of research is revealing associations between birth defects (缺陷) and a father's age, alcohol use and environmental factors, say researchers atGeorgetown University Medical Center. They say these defects result from epigenetic changes that can potentially affect multiple generations.The study, published in theAmerican Journal of Stem Cells, suggest both parents contribute to the health status of their offspring — a common sense conclusion which science is only now beginning to demonstrate, says the study's senior investigator, Joanna Kitlinska, PhD, an associate professor in biochemistry, and molecular and cellular biology.“We know the nutritional, hormonal and psychological environment provided by the mother permanently influences organ structure, cellular response and gene expression in her offspring,” she says.“But our study shows the same thing to be true with fathers — his lifestyle, and how old he is, can be reflected in molecules that control gene function,” she says. “In this way, a father can affect not only hisimmediate offspring, but future generations as well.”For example, a newborn can be diagnosed with fetal (胎儿的) alcohol spectrum disorder (FASD), even though the mother has never consumed alcohol, Kitlinska says. “Up to 75 percent of children with FASD have biological fathers who are alcoholics, suggesting that preconceptual paternal alcohol consumption negatively impacts their offspring.”Advanced age of a father is correlated with elevated rates of certain diseases, and birth defects in his children.A limited diet during a father’s preadolescence has been linked to reduced risk of cardiovascular death in his children and grandchildren. Paternal obesity is linked to enlarged fat cells, changes in metabolic regulation, diabetes, obesity and development of brain cancer. Psychosocial stress on the father is linked to defective behavioral traits in his offspring. And paternal alcohol use leads to decreased newborn birth weight, marked reduction in overall brain size and impaired cognitive function.“This new field of inherited paternal epigenetics needs to be organized into clinically applicable recommendations and lifestyle alternations,” Kitlinska says. “And to really understand the epigenetic influences of a child, we need to study the interplay between maternal and paternal effects, as opposed to considering each in isolation.”8. What’s the message the writer conveys in the passage?A. Both parents contribute to the health status of their offspring.B. Father’s age and lifestyle are tied to birth defects.C. Father plays a more critical role in birth defects.D. Birth defects can potentially affect multiple generations.9. What can we infer from the example in Paragraph 5?A. FASD can only be diagnosed in a newborn whose father is addicted to alcohol.B. A newborn will not contract FASD if his mother has never consumed alcohol.C. A father’s lifestyle can negatively impact his offspring.D. Most children have biological fathers who are alcoholics.10. Which of the following situations is less likely to lead to children’s birth defects?A. Having a father with a limited diet.B. Having a father who is an alcoholic.C. Having an overweight father.D. Having a father with psychosocial stress.11. What will the research probably continue to focus on in the part that follows?A. The maternal epigenetic influences of a child.B. The ways to avoid negative paternal influence on children.C. The clinical application of the research findings.D. The interaction between maternal and paternal effects.DA single toy catches a child's attention for a limited period of time, but a box of items that allows a child to build their own toys will catch their imagination for years to come. This brilliant idea already exists in real product form, and it's called Toyi.Toyi is described as an eco-friendly creative building kit, and it recently won the well-known IF Design Award. It came from Istanbul, Turkish, where a young female designer named Elif Atmaca first came up with the idea for it when she wanted to help the kids living in disadvantaged areas. These children do not have access to the variety of interesting toys that wealthier children do.Toyi Atmaca's design allows children to transform what are around them into clever toys. It consists of sticks, junction parts, flexible connectors, toy body parts like feet, eyes, hands, and wheels that can be used to turn old water bottles, cups, boxes, towels, etc. into cute, clever, and unique playthings. This toy kit upcycles(升级利用) materials that would otherwise go to waste, turning a recycling bin into a treasure container.“Our initial target was to deliver Toyi kits to only disadvantaged children in Turkish,” Atmaca told the media. But during a research conducted with around300 children, .she realized that the restriction on being creative went beyond any boundary. “I saw that everything was planned and shaped by grown-ups, blocking the kids' imagination in a significant way,” said Atmaca.Atmaca concluded that each kid needed space where he or she could freely create. She explained the entire process should be left to kids’ creativity, reminding teachers and all grown-ups that child-led play was an excellent way for children to develop lifelong skills.Toyi's creators are now considering distributing the kits to as many children as possible around the world through different international NGOs. Atmaca notes that for each Toyi kit sold out, they will also donate one kit toa disadvantaged child through different partnerships around the world.12. Why did Atmaca design Toyi at first?A. To win the famous IF Design Award.B. To help poor kids make their own toys.C. To protect the environment in Istanbul.D. To recycle all the waste in the dustbin.13. Which is probably the product made with the toy kit of Toyi?A. A new picture of a young boy.B. A computer with high technology.C. A treasure container from a dustbin:D. A six-armed “robot” from a water bottle.14. How do the toy kits help improve the children's ability?A. It provides the kids various types of toys.B. It offers space for the kids’ creative minds.C. It changes the poor kids' living conditions.D. It teaches the kids to share joys with others.15. What is the new target for Atmaca and her partners?A. Donating toykits to more poor children.B. Selling toy kits to every kid in the world.C. Designing new toy kits for kids and adults.D. Doing further research on the kids' demands.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。

Why not come but join them? If you came here, I will do how I can toand come whathelp you.书面表达:Dear Jenny,How is your survey on mobile payment going? I’m glad I can help with it.It is generally believed that China is the largest mobile payment market. Nowhere else is the cashless trend more obvious than in China. Most of us are used to paying by scanning QR codes whatever we buy—books, clothes, and electronic devices, to name a few, which is a glimpse into the life of most Chinese like me and my family.With the widespread use of mobile payment, Wechat or Alipay is the most convenient and safest way to pay. We rarely need to carry a wallet or cash at all. Besides, never will we worry about getting fake notes or having to count change. In short, mobile payment has greatly changed people's life in China.Personally, I think mobile payment should be encouraged. First, it has won over consumers with its convenience. Another advantage is that there are often discounts if you make mobile payment, as major online payment platforms are competing to have more consumers use their service.I hope my explanation can be of some help to you. Wish you good luck.Yours faithfully,Li Hua1。
山西大学附中2019届高三下学期3月模块诊断 语文 答案
山西大学附中2018-2019学年高三第二学期3月模块诊断语文试题答案1. C 本题考查的是对材料内容的理解能力。
题干问的是“下列对材料相关内容的表述，不正确的一项是”，这是考查学生对文本内容的筛选和概括。
首先应浏览选项的内容，然后到文中找到相关的句子，最后进行辨析。
选项C，“被调查教师与袁济喜教授的看法截然不同”理解有误。
在导致传统文化教育活动开展困难的因素这一问题的认识上，被调查教师与袁济喜教授的看法并非截然不同，如都有提到师资问题。
故答案选C。
2. C 本题考查的是对材料内容的理解和分析的能力。
题干问的是“下列对材料相关内容的分析和理解，不正确的一项是”，这是考查学生对文本内容的筛选和概括。
首先应浏览选项的内容，然后到文中找到相关的句子，最后进行辨析。
选项C，“不如在现有课程体系中加入一些传统文化的元素等方式好”说法错误。
根据对原文的理解：“在现有课程体系中加入一些传统文化的元素等方式”是“嵌入式、掺沙子式的模式”的具体表现形式。
故答案选C。
3. （1）材料三侧重顶层设计与基层实施之间的差距，强调要从师资和课程的角度落实传统文化教育。
（1分）材料四侧重基层落实，主要论述如何开展好传统文化进校园活动。
（1分）（2）课程方面：整合现有教材，开发有学校特色的校本课程。
开展师生参与度高且具有文化内涵的校园文化活动。
（2分）师资方面：采取专兼职教师结合的办法，聘请专人开展传承项目教育教学活动。
利用网络优质资源进行传统文化教育，弥补师资不足的“短板”。
（2分）4．D5．B （解析：A项是关于称谓的考查。
开国之君，功劳最大，故而维承带位的子孙尊其为“太祖”C项考查的是古代官制。
D项主要考查的是古代专有名词。
B项主要考查得是古代言职的升降。
前四个“拜”“授” “拔”“擢”都可以指升言，而后两个“转”“调”多指言职的调动，不一定是升职。
所以，B项的表述有误，是正确选项。
）6．B （解析：B项“在陈友谅攻下龙湾之后”错，“友谅薄龙湾”意指陈友谅进逼龙湾。

A much smaller number gain fame because they have done something important and worthwhile with their abilities. Rishab Jain is among the latter. In 2018, 13-year-oldRishab developed a way to use AI technology to help pancreatic(胰腺的) cancer patients and won the3MYoung Scientist Challenge, a nationwide middle-school science competition, and its $25,000 prize.In the last stage of the contest, Rishab competed againstnine other finalists at the 3M Innovation Center(创新中心) in St.Paul,Minnesota. Leading up to the big meet, each finalist had partnered with a scientist to further develop their inventions.Rishab explains what led him to create his invention. First,a family friend died of cancer. Then Rishab learned about how deadly pancreatic cancer is, and that its low survival rate is due to how difficult it is to treat. "I'm also into programming, so I was learning about AI technology. I decided to try to solve a real-world problem using it."His winnings have been put in further research and in his nonprofit Samyak Science Society, which helps poor children enter the STEM (science, technology, engineering and math) education. Rishab is also raising awareness about pancreatic cancer. These efforts make him quite different from teenagers of his age. Considering becoming a biomedical engineer or a doctor一or both, he has also put some money aside to further his own learning. Almost certainly the doors of higher education will open wide to him before he even knocks.That's an outstanding outlook for one so young. Rashib is committed to helping very sick people in need. He is also providing teenagers of his age with a much-needed model of what kinds of things youth can achieve.1. What can we learn about the 3M Young Scientist Challenge in 2018?A. It was intended to solve medical problems.B. It was a nationwide AI competition for teenagers.C. It offered the finalists an opportunity to work with scientists.D. It allowed the finalists to learn AI technology in the 3M center.2. How did Rishab win the 3M Young Scientist Challenge?A.He showed excellent programming ability.B. He figured out the survival rate of pancreatic cancer.C. He introduced poor children to STEM education.D. He applied AI technology to treating pancreatic cancer.3. Which of the following best describes Rishab?A. Talented and caring.B. Independent and humorous.C. Responsible and patient.D. Polite and inspiring.BThe AI research arm of Alibaba created a machine learning model that received a higher score on the Stanford Question Answering Dataset than humans. The database consists of more than 100,000 questions to test reading comprehension.In early January this year the Alibaba AI software machine scored 82.44 on the test while humans scored 82.304. Besides, computers and AI have already defeated humans, for example in games such as chess. However, it seemed that language skills were superior in humans as machines find languages hard to master.A large number of call center employees, often in developing countries, may be out of work soon if the AI robots are cheaper and as effective as human labor. Soon when you phone a company for information the conversation will go like this: “ We are sorry but all our robots are busy right now. We value your call. Please stay on the line until a robot is free to serve you. There are just 12 callers ahead of you.” A robot will serve you some popular tunes while you wait.Si Luo, who is a chief scientist of natural language processing at Alibaba’s AI research group noted that questions such as “What causes rain?” can now be answered with a high degree of accuracy by robots. Si Luo said, “ We believe the foundational technology can be gradually applied to a lot of applications such as customer service, museum tutorials, and online responses to inquiries from patients, freeing human efforts in a new way.”Si Luo’s team is working closely with Ali Xiaomi, a mobile customer service chatbot. Ali Xiaomi can be customized to be used on Alibaba’s platforms such as Taobao and Tmall. The new AI robots could answer consumers’ questions as they did the Stanford questions. The robots would look for the answers from prepared information. However, there are limits to what the system will be able to do. If questions do not have clear-cut answers, or the questions asked are too unclear or ungrammatical, the robot may not be able to deal with them.4. What can we learn about the Alibaba AI software machine?A. It has been tested in some areas.B. It has become popular since January.C. It has offered a special learning style.D.

Countries all across the world are actively promoting their wilderness regions-such as mountains, Arctic lands, deserts, small islands and wetlands— to high-spending tourists. The attraction of these areas is obvious: by definition, wilderness tourism requires little or no initial investment. But that does not mean that there is no cost.Once a location is established as a main tourist destination, the effects on the local community are profound. Hill-farmers can make more money from foreign travellers than working in their fields. It is not surprising that many o£ them give up their farm-work. In some hill-regions, this has led to a serious decline in farm output and a change in the local diet, because there is lacking labour to maintain terraces and irrigation systems. The result has been that many people in these regions have turned to outside supplies of rice and other foods.InArcticand desert societies, year-round survival has traditionally depended on hunting animals and fish and collecting fruit over a ly short season. However, as some inhabitants become involved in tourism, they no longer have time to collect wild food; this has led to increasing dependence on bought food and stores. What should they do if these new sources of income dry up?The physical impact of visitors is another serious problem associated with the growth in adventure tourism. Much attention has focused on erosion along major roads, but perhaps more important are the forest destruction and impacts on water supplies arising from the need to provide tourists with cooked food and hot showers. In both mountains and deserts, slow-growing trees are often the main sources of fuel and water supplies may be limited through heavy use.8. Why are some countries promoting the wilderness regions to tourists?A. The wildness regions are accessible to tourists.B. The landscapes there are beautiful and unique.C. Developing tourism there doesn't need much investment.D. Lots of high-spending tourists prefer such remote regions.9. What is the effect of tourism on the local community?A. Many hill farmers have turned to outside supplies of foods.B. There is enough labour to maintain terraces and irrigation systems.C. Farm output there has increased and local diet has changed.D. The local people's new sources of income will dry up soon.10. Which might be the best title of the passage?A. The future of wilderness tourism.B. The impacts of wilderness tourism.C. The destruction of wilderness tourism.D. The disadvantages of wilderness tourism.11. If there is one more paragraph following the last paragraph, what will it talk about?A. The effects on local people.B. The solutions tothese problems.C. The choices of adventure tourists.D. The reasons for visiting remote areas.DI have a memory of being about five years old, picking up a beautiful grilled(烧烤的）cheese sandwich made for me by my hard —working mother and turning it over to see that theother side was burned. Suddenly what I thought was the perfect sandwich was not so perfect. Mom had tried to hide that fact from me. There was no question; I ate it anyway without complaining. However, that moment has stuck in my mind for many years. Now, at the age of 43 as a mother of two children and as a biology professor where I am routinely the "academic mother" of hundreds of students every year,I find that I believe inThe Grilled Cheese Principle.Here is what I mean Making a grilled cheese sandwich is easy right? But when I think of how many burned grilled cheese sandwiches I have eaten, or I have made myself, I realize that most of the grilled cheese sandwiches I have known have had at least one burned side. The thing is that although it is a ly easy thing to make, I can also easily lose focus, and before long the sandwich is burned. For my mother, the first side was usually perfect and the second side got burned due to her being distracted. For me,I have tended to burn the first side,but then I more carefully monitor the second side.Either way,the grilled cheese sandwich suffers because it has not been given the attention it deservesSo, I have learned that even the simplest task deserves my full attention. When I am multi-tasking, I am doingnone of the tasks well. And when I allow myself to be distracted, I am not in the present moment — not paying attention to the small details of living or enjoying the processSo now, I believe the best way to make a perfect grilled cheese sandwich is to make only one at a time and give it my full attention.12. How did the writer react to the sandwich with burned side?A. She ate it with some complaintsB. She showed no interest.C. She thought it was still perfectD. She was deeply impressed with it13. What doesThe Grilled Cheese Principlemean?A. Even simple things deserve full attentionB. Losing focus makes the sandwich burnedC. Self-made sandwiches are always burnedD. we should make only one sandwich at a time14. Which of the following can we infer from the passage?A. Everything cannot be done well without full attentionB. Moms always like to lie to kids when they have done something wrongC. We can lose focus more easily when we do easy things.D. Multi-tasking can be an obstacle to the achievement of tasks.15. What does the writer mainly want to tell us?A. Nothing is perfectB. Learn to appreciate the burned sandwichesC. Devote yourself to one thing at a time.D. Never do multi-tasks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。

概率与统计（三）
1.某食品厂为了检查一条自动包装流水线的生产情况，随机抽取该流水线上40件产品作为样本称出它们的重量(单位：克)，重量的分组区间为(]490,495，(]495,500，…，(]510,515，由此得到样本的频率分布直方图，如图所示．
（1）根据频率分布直方图，求重量超过505克的产品数量；
（2）在上述抽取的40件产品中任取2件，设Y 为重量超过505克的产品数量，求Y 的分布列；
（3）从该流水线上任取5件产品，求恰有2件产品的重量超过505克的概率．
2．为了让学生了解更多“奥运会”知识，某中学举行了一次“奥运知识竞赛”，共有800名学生参加了这次竞赛，为了解本次竞赛成绩情况，从中抽取了部分学生的成绩(得分均为整数，满分为100分)进行统计．请你根据尚未完成的频率分布表，解答下列问题：
分组 频数 频率 60.5～70.5 0.16 70.5～80.5 10 80.5～90.5 18 0.36 90.5～100.5
合计
50
(1)若用系统抽样的方法抽取50个样本，现将所有学生随机地编号为000，001，002，…，799，试写出第二组第一位学生的编号；
(2)填充频率分布表的空格(将答案直接填在表格内)，并作出频率分布直方图； (3)若成绩在85.5～95.5分的学生可获二等奖，问参赛学生中获得二等奖的学生约为多少人？
(3)在被抽到的学生中获二等奖的人数约是9＋7＝16(人)，占样本的比例是16
50＝0.32.即
获二等奖的概率约为32%，所以获二等奖的人数估计为800×32%＝256(人)．
3.【吉林省实验中学2015届高三年级第四次模拟考试数学（文）试卷】某市统计局就某地居民的月收入调查了 10 000 人，并根据所得数据画出样本的频率分布直方图（每个分组包括左端点，不包括右端点，如第一组表示收入在[1 000,1500））．
（Ⅰ）求居民收入在[3 000,3 500）的频率；
（Ⅱ）根据频率分布直方图算出样本数据的中位数；
（Ⅲ）为了分析居民的收入与年龄、职业等方面的关系，必须按月收入再从这 10 000 人中按分层抽
样方法抽出 100 人作进一步分析，则月收入在[2 500,3 000）的这段应抽取多少人？
试题分析：（Ⅰ）根所频率分布直方图的意义，居民收入在[3 000,3 500）内的频率等开该组所所应的长方形的面积；（Ⅱ）根据中位数的定义，在频率分布直方图中，中位数两侧的直方图的面积相等从而求解.
（Ⅲ）根据分层抽样的原理，每组数据的入样比例均相等，都等于总的抽样比
1 100
.
点评：(1)通常我们对总体作出的估计一般分成两种，一种是用样本的频率分布估计总体的频率分布，另一种是用样本的数字特征估计总体的数字特征．
(2)在频率分布直方图中，纵轴表示，数据落在各小组内的频率用各小长方形的面积表示，各小长方形的面积总和等于1.
(3)连接频率分布直方图中各小长方形上端的中点，就得到频率分布折线图．随着样本容量的增加，作图时所分的组数增加，组距减小，相应的频率分布折线图就会越来越接近于一条光滑的曲线，统计中称之为总体密度曲线，它能够更加精细的反映出总体在各个范围内取值
的百分比．。
