I was able to buy it a little over a year ago because I had my relatives give me money for my birthday instead of a lot of clothes that wouldn’t fit.I let a salesclerk fool me into buying a discontinued model , I realized this a day late, when I saw newspaper advertisements for the set at seventy-five dollars less than I had paid, The set worked so beautiful when I first got it home that I would keep it on until stations signed off for the night, Fortunately, I didn’t got any channels showing all-night movies or I would never have gotten to bed.Then I started developing a problem with the set that involved static (静电) noise For some reason, when certain shows switched into a commercial, a loud noise would sound for a few seconds. Gradually, this noise began to appear during a show, and to get rid of it, I had to change to another channel and then change it back. Sometimes this technique would not work, and I had to pick up the set and shake it to remove the sound. I actually began to build up my arm muscles(肌肉) shaking my set.When neither of these methods removed the static noise ,I would sit helplessly and wait for the noise to go away.At last I ended up hitting the set with my fist,and it stopped working altogether .My trip to the repair shop cost me $62, and the set is working well now,but I keep expecting more trouble.1. Why did the author say he was fooled into buying the TV set?A. He got an old module than he had expected.B. He couldn’t return it when it was broken.C. He could have bought it at a lower price.D.

We should wash our hands before touching a door handle.24. The text probably comes from .A. a guide bookB. a popular magazineC. a book reviewD. an official documentBAt thirteen, I was diagnosed（诊断）with kind of attention disorder. It made school difficult for me. When everyone else in the class was focusing on t asks, I could not. In my first literature class, Mrs. Smith asked us to read a story and then write on it, all within 45 minutes. I raised my hand right away and said, “Mrs. Smith, you see, the doctor said I have attention problems. I might not be able to do it.”She glanced down at me through her glasses, “you are no different from your classmates, young man.”I tried, but I didn’t finish the reading when the bell rang. I had to take it home.In the quietness of my bedroom, the story suddenly all became clear to me. It was about a blind person, Louis Braille. He lived in a time when the blind couldn’t get much education. But Louis didn’t give up. Instead, he invented a reading system of raised dots（点）, which opened up a whole new world of knowledge to the blind.Wasn’t I the “blind” in my class, being made to learn like the “sighted” students? My thoughts spilled out and my pen started to dance. I completed the task within 40 minutes. Indeed, I was no different from others; I just needed a quieter place. If Louis could find his way out of his problems, why should I ever give up?I didn’t exp ect anything when I handed in my paper to Mrs. Smith, so it was quitea surprise when it came back to me the next day with an “A” on it. At the bottom ofthe paper were these words: “ See what you can do when you keep trying?”25. The author didn’t finish the reading in class because .A. He was new to the classB. He w as tired of literatureC. He had an attention disorderD. He wanted to take the task home26. What do we know about Louis Braille from the passage?A. He made a great inventionB. He had good sightC. He gave up readingD. He learned a lot from school27. What was Mrs. Smith’s attitude to the author at the end of the story?A. AngryB. ImpatientC. SympatheticD. Encouraging28.What is the main idea of the passage?A. The disabled should be treated with respect.B.A teacher can open up a new world to students.C. Everyone needs a hand when faced with challenges.D. One can find his way out of difficulties with efforts.CIt is well known that the Japanese people’s love of fish is almost as a bee’s interest in honey. As fish populations were decreasing, fishing companies were forcedto fish further and further away from the shore. Then they had a big challenge(挑战)－how to keep the fish fresh for longer. So they decided to keep the fish stored in freezers on the boats. But the public did not like f rozen fish. So again the fishing companies had a new bigger challenge. What they decided to do was to have fish tankson their boats. After catching fishes, they would put them in the tanks and keep them living there until they got back to shore. But in this protected environment, lacking predators (掠食者)，the fish stopped moving around. The Japanese public felt these dull fish did not taste fresh, which had an unpleasant effect upon sales. Once again the fishing companies had an even bigger challenge.Stop for a minute! Before we go any further, I would like to ask “What are your challenges? How do you handle an unexpecte d challenge?” May I think it this way that you should try to attack your challenges? Conquer（战胜） them with a Swiss Army knife. Take the most proper and simple tool that you can adopt to deal with your situation.Now back to our story. How did the Japanese finally figure out the fresh fish problem？Sharks! You might think the same. Sharks were caught and put into the tanks with other fishes. Don’t sharks eat fish? Well, they do eat a few fish, but they did also keep more fish active and alert (警觉的). The fish stay fresh because they are challenged.Now, try to keep yourself fresh by finding your own shark to offer yourself a challenge in your own business and career.29. The main reason for the fishing company to fish in the far sea was that .A. the fishes farther away from the sea tasted fresherB. the fish resource near the shore was on the decreaseC. people would prefer eating fresh fishes to less fresh onesD. it was getting harder and harder to keep fishes fresh30. Which of the following statements is true?A. The fish kept in tanks didn’t sell well because of their taste.B. Japanese people love honey as much as a bee does.C. The fish stored in the protected environment tasted the best.D. The fish kept in tanks didn’t taste fresh bec ause they died before reachingthe restaurant.31. The underlined part of the last paragraph means “ .”A. Sharks are usually compared to the challenges in people’s lifeB. Try to find a big shark and you will meet your challengeC. If you went fishing, you might do as the fishing companies didD. To succeed in life, you should always be ready to meet challengesDMany Western people are not used to sitting on the floor any more. In Japan, however, sitting upright on the floor is common in different situations. For example, meals are traditionally had when people sit on the tatami (榻榻米) floor around a low table. Also during the tea ceremony and other traditional events, one sits on the floor.The formal way of sitting for both men and women is kneeling upright. People who are not used to sitting in this style may feel uncomfortable after a few minutes, and their legs may go numb. However, foreigners are not usually expected to be able to sit in this style for a long time, and an increasing number of Japanese people themselves aren’t able to do so, owing to a more westernized lifestyle.In other situations, men usually sit cross-legged, while women sit on their kneeslaying both legs to one side. The former sitting style is considered wholly male, while the latter is considered completely female.The most important guest sits on the honored seat which is set farthest from the entrance. If there is a tokonoma (壁龛) in the room, the guest should be seated in front of it. The host or the least important person is supposed to sit next to the entrance. Of course, there are other things to be considered in each particular case.32. Which of the following situations is NOT mentioned in the passage?A. When traditional events are held.B. When a tea ceremony is held.C. When men and women meet.D. When meals are traditionally had.33. According to the passage we can learn that ______.A. more and more Japanese sit in the formal wayB. foreigners should always sit in the formal style in a Japanese homeC. men and women in Japan sit in the same informal wayD. men shouldn’t sit on their knees laying both legs to one side34. When some guests are in a Japanese home, _______should sit nearest to the entrance.A. the most important guestB. both the host and the hostessC. the host or the least important personD. the host himself35. What is the passage mainly about?A. How foreigners should sit in Japanese homes.B. How and where to sit in Japanese homes.C. How foreigners should behave in Japanese homes.D. Where to sit in Japanese homes.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。

大石桥市第二高级中学2015-2016学年高二6月月考英语试题第一部分听力（省略）第二部分阅读理解（共两节，满分40分）第一节（共15小题，每题2分，满分30分）阅读下列短文，从每题所给的四个选项中，选出最佳选项。

AWatercolor is the oldest paints known. It dates back to the early cave men who discovered they could add lifelike qualities to drawings of animals and other figures on the walls of caves by mixing the natural colors found in the earth with water.Fresco(壁画), one of the greatest of all art forms, is done with watercolor. It is created by mixing paints and water and applying these to wet plaster(灰泥). Of the thousands of people who stand under Michelangelo's heroic ceiling in the Sistine Chapel, very few know that they are looking at perhaps the greatest watercolor painting in the world.The invention of oil painting by the Flemish masters in the fifteenth century made fresco painting go down-hill, and for the next several centuries watercolor was used mainly for doing sketches(素描) or as a tool for study. It was not until the eighteenth and nineteenth centuries that English painters put back watercolor as a serious art form. The English have a widely-known love for the outdoors and also small, private pictures. The softness of watercolor had a remarkably strong attraction for them.The popularity of watercolor continued to grow until in the twentieth century. The United States passed England as the center for watercolor, producing such well-known watercolor artists as Thomas Eakins and Andrew Wyeth.21．What is the passage mainly about?A. The gradual weakness of fresco painting.B. Oils having more power or influence over watercolor.C. The rediscovery of watercolor in England.D .The start and development of watercolor.22．The first watercolor artists were ______.A. early cave menB. Italian fresco artistsC. Flemish mastersD. English artists of the 18th century23．According to the passage, watercolor painting was put back in England because ______.A. it was easy to use outdoorsB. it was a strong mediumB. it was extremely bright in color D. it was well suited to popular tastes24．What would the next paragraph most probably deal with?A. the works of famous American watercolor artists.B. The weakness of oils as popular paints.C. Techniques of producing watercolor.D .Modern American oil painters.BDid you know that women’s brains are smaller than men’s? The average women’s brain weighs 10% less than men’s. Since research has shown that the bigger the brain, the cleverer the animal, men must be more intelligent than women. Right? Wrong. Men and women always score similarly on intelligence tests, despite the difference in brain size. Why? After years of study, researchers have concluded that it’s what’s inside that matters, not just the size of the brain. The brain consists of “grey matter” .It has been suggested that smaller brain appears to work faster, perhaps because the two sides of the brain are better connected in women. This means that little girls tend to learn to speak earlier, and that women can understand sorts of information from different sources at the same time. When it comes to talking to the boss on the phone, cooking dinner and keeping an eye on the baby all at the same time, it’s women who come out on top every time.There are other important differences between two sexes. As white matter is the key to spatial(空间的) tasks, men know better where things are in relation to other things. “A great footballer always knows where he is in relation to the other players, and he knows where to go,” says one researcher. That may explain one of life’s gre at mysteries: why men refuse to ask for directions … and women often need to!The differences begin when fetuses(胎儿) are about nine weeks old, which can be seen in the action of children and young as one. A boy would try to climb a barrier (障碍物) before him or push it down while a girl wouldattract help from others. These brain differences also explain the fact that more men take up jobs that require good spatial skills, while more women speech skills. It may all go back to our ancestors(祖先) ,among whom women needed speech skills to take care of their babies and men needed spatial skills to hunt, according to one research.If all this disappoints you, it shouldn’t. “The brain changes throughout our lives according to what we do with it.” says a biologist.25．Which of the following is true according to the first paragraph?A. Women’s brain is 10% less than men’s.B. Grey matter plays the same role as white matter.C. Grey matter controls thinking in the brain.D. Both sexes have the same amount of white matter.26．What can we infer from the second and third paragraphs?A. Women prefer doing many things at a time.B. Men do better dealing with one job at a time.C. Women do not need to tell directions.D. Men have weaker spatial abilities.27．Which of the following do you agree with according to the fourth paragraph?A. Young boys may be stronger than young girls.B. More women take up jobs requiring speech skillsC. Women may have stronger feelings than men.D. Our ancestors needed more spatial skills.28．What is the writer’s attitude in writing this passage?A. Defensive.B. Persuasive.C. Supportive.D. Objective.CA serious problem for today’s society is who should be responsible for our elderly and how to improve their lives. It is not only a financial problem but also a question of the system we want for our society. I would like to suggest several possible solutions to this problem.First, employers should take the responsibility for their retried employees. To make this possible, a percentage of profits should be set aside for this purpose. But when a company must take life long responsibility for itsemployees, it may suffer from a commercial disadvantage due to higher employee costs.Another way of solving the problem is to return the responsibility to the individual. This means each person must save during his working years to pay for his years of retirement. This does not seem a very fair model since some people have enough trouble paying for their daily life without trying to earn extra to cover their retirement years. This means the government might have to step in to care for the poor.In addition, the government could take responsibility for the care of the elderly. This could be financed through government taxes to increase the level of pensions. Furthermore, some institutions should be created for senior citizens, which can help provide a comfortable life for them. Unfortunately , as the present situation in our country shows, this is not a truly viable answer. The government can seldom afford to care for the elderly, particularly when it is busy trying to care for the young.One further solution is that the government or social organizations establish some workplaces especially for the elderly where they are independent.To sum up, all these options have advantages and disadvantages. Therefore, it is reasonable to expect that some combination of these options may be needed to provide the care we hope to give to our elderly generations. 29．What is the passage mainly about?A. The problem faced by the old in society.B. Why we should take responsibility for the old.C. How we can improve the lives of the old.D. Where the old can go to get their pensions.30．According to the passage, how can the government help to improve the lives of retired people?A. Set aside some profits to help people with problems after they retireB. Increase saving levels of people during their working yearsC. Increase the discounts for food and transport for the oldD. Make available pensions for those who have retired31．The underlined word “viable” most probably means ____.A. impossibleB. practicalC. usefulD. successful32．What can be concluded from the passage?A. Taking care of the old is mainly an issue of moneyB. Employers should allow their workers to retire at a later ageC. Becoming independent should be the goal of most old peopleD. There is no single solution to the problem of the oldDWhen I was a child, I often dreamed of the time when I could leave home and escape to the city. We lived on a farm, in the winter especially, we were quite cut off from the outside world. As soon as I left school, I packed my bags and moved to the capital. However, I soon discovered that my life has its problems ,too.One big disadvantage is money. It costs so much to go out, not to mention basics like food and housing. Another disadvantage is pollution. I suffer from asthma(哮喘), and at times the air is so bad that I am afraid to go outside. Then there is the problem of traveling round. Although I have a car, I seldom use it because of the traffic jams. One choice is to go by bicycle, but that can be quite dangerous.Of course there are advantages. First, there is so much to do in the city, whatever you tastes in culture or entertainment(娱乐活动). Besides, there are wonderful jobs and greater chances of moving to a more important job or position. Finally, if you like shopping, the variety of goods is very surprising --- and , what is more, shops are often only a short walk away.Is life better then, in the city? Perhaps it is , when you are in your teens(十几岁)or twenties. However, as you get older, and especially if you have small children, the peace of the countryside may seem preferable. I certainly hope to move back there soon.33．Which of the following is true about the writer?A. He is very old now.B. He is in good health.C. He prefers driving a car.D. He lives in the city now.34．In the passage, the writer tries to __________.A. express his opinions about way of lifeB. describe his life in the countrysideC. an interest in the outside worldD. persuade the reader to live in the city35．How is the passage mainly developed?A. By inferring.B. By comparing.C. By listing examples.D. By giving explanations.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。

AThe house was quiet at 5 am and Tim’s mother was asleep. Only the sound of the b ig freezer broke the quiet. He’d dreamt of the cave last night. The purring (轻微颤动声) of the freezer had been the sea.Tim pulled on a sweater and put some apples into his schoolbag. It was too early for breakfast. He’d eat after he’d been through the cave, sitting on the rocks and staring at the sea. He wished he had a proper pack. His schoolbag would have to do. What else? Sandwiches-but his mother might wake up if he started pulling out bread for sandwiches, she' d want to know why he had to leave so early. He settled for some biscuits, and left a note stuck to the table: Gone to Michael’s. Back tonight, Tim.The sky was high and soft and light outside, though the sun still wasn't up. Even the highway up the hill was quiet as he made his way down the street. The wind from the sea was fresh and sweet.The sand hills still breathed heat from yesterday’s sun, though the top of the sand was cool. He ran down to the beach impatiently, but there was no one, just dry sand dancing in the early wind and seabirds marching up and down watching the waves.The light changed suddenly. The first rays of sunlight stretched across the sea. The sun was pushing its way over the edge of the world.Over the first rocks, along to the point, Tim glanced back. The beach was still empty. The sun sailed higher in the sky.He could see the cave now, even darker in the morning light. The sand turned silver then dark gold as the water flowed away from it. He had to force himself to go closer. Why was it so much more mysterious now? But it would be silly to go back now after so much trouble. He needn't go in all the way...21. What did Tim do at the beginning of the story?A. He put a sweater in his schoolbag.B. He had breakfast at home.C. He left a note on the freezer.D. He left the house quietly.22. What made it possible for Tim to see the entry to the cave?A. The height of the first rocks.B. The change in the position of the sun.C. The ups and downs of the waves.D. The vast stretch of the sunlit beach.23. Which of the following statements is TRUE according to the story?A. Tim was the only person on the beach.B. Seabirds flew away when Tim arrived.C. The sea looked like a piece of gold.D. The sky got dark as Tim reached the cave.24. In the story, Tim’s mood changed from_________.A. loneliness to crazinessB. anxiousness to excitementC. eagerness to nervousnessD. helplessness to happinessBYou may know your mother, but how well do you really know Mother’s Day? Cards, flowers, sales, TV specials, and a day off for someone who really deserves (应得) it ---- those are what probably come to mind for many people when they think of Mother’s Day. But there’s more to the story.The earliest Mother’s Day celebrations were held during spring in ancient Greece. The celebrations honored Rhea, the Mother of the gods. During the 1600’s, England celebrated a day called Mothering Sunday. On this day even servants were given the day off to spend with their families. A mothering cake was even served with the family meal.In the US, Mother’s Day began in 1872 when Julia Ward Howe, who wrote the words to the famous song The Battle Hymn of the Republic, suggested it as a day devoted to peace. But it didn’t really become popular until 1907 when Anna Jarvis started a campaign to honor mothers. She believed that mothers could help people get over the pain they experienced during the Civil War. The US isn’t alone in devoting a day to mothers. Many other countries including Denmark, Finland, Italy, Turkey, Australia, Japan, and Belgium also honor their mothers in May. Other countries honor their mothers at different times of the year.Learning more about Mother’s Day and celebrating Mother’s Day are important, but probably not as important as understanding what your own mother, or grandmother, or aunt has really done for you. And that will certainly be appreciated more than one day in a year.25. What is the passage mainly about?A. The reason why people celebrate Mother’s Day.B. The ways people honor mothers.C. The history of Mother’s Day.D. The contribution of mothers.26. Where was the earliest Mother’s Day celebrated?A. In ancient Greece.B. In the US.C. In England.D. In Italy.27. We can learn from the passage that _____.A. Rhea is the mother of a king in ancient GreeceB. all the countries do n’t celebrate Mother’s Day in MayC. only mothers were given a day off on Mothering SundayD. it was in 1872 that Mother’s Day really came into being28. The last paragraph tells us that _____.A. all the people should celebrate Mother’s Day by doing something good to their mothers.B. only mothers are honored on Mother’s DayC. understanding mothers’ work is more important than just celebrating Mother’s DayD. people should celebrate Mother’s Day every dayCA warm drink of milk before bed has long been the best choice for those wanting a good night’s sleep. But now a study has found it really does help people nod off—if it is milked from a cow at night.Researchers have discovered that “night milk” contains more melatonin(褪黑激素), which has been proven to help people feel sleepy and reduce anxiety.The study, by researchers from Seoul, South Korea, involved mice being fed with dried milk powder made from cows milked both during the day and at night.Those given night milk, which contained 10 times the amount of melatonin, were less active and less anxious than those fed with the milk collected during daytime, according to the study published in The Journal of Medicinal Food.Night milk quickened the start of sleep and caused the mice to sleep longer.While the effect of cows milk harvested at different time has not been tested on humans up to now, taking melatonin drugs has been suggested to those who are struggling to fallasleep at night.Previous studies have also indicated that milk can be excellent for helping sleep because of the calcium (钙)content, which helps people to relax.Milk is also sugar-free and additive-free with nutritionists recommending(推荐) skimmed milk as the best choice before bed as it is the least fattening. The more fat you take in before bedtime, the greater burden you will put on your body at night.29. According to the text, the mice fed with daytime milk_______.A. started sleep more easilyB. were more anxiousC. were less activeD. woke up later30. Which of the following is true of melatonin according to the text?A. It’s been tested on mice for ten timesB. It can make people more energeticC. It exists in milk in great amountD. It’s used in sleeping drugs31. What can be a suitable title for the text?A. Night Milk and SleepB. Fat Sugar and HealthC. An Experiment on MiceD. Milk Drinking and Health32. How does the author support the theme of the text?A. By giving examples.B. By stating arguments.C. By explaining statistical data.D. By providing research results.D33. When will the job start?A.

Judy, IT staff with night cla sses, children’s basketball team coachC. Ted, computer major, basketball fan, free on evenings and weekendsD.

The card is written in a _______ way.A. urgentB. annoyedC. humorousD. concernedBIn 1943, when I was 4, my parents moved from Coeur d'Alene, Idaho, to Fairbanks, Alaska, where adventure was never very far away.We arrived in the summer, just in time to enjoy the midnight sun. All that sunlight was fantastic for Mom's vegetable garden. Working in the garden at midnight tended to throw her timing off, so she didn't care much about my bedtime.Dad was a Railway Express agent and Mom was his clerk. That left me in a mess.I usually managed to find some trouble to get into. Once I had a little fire going in the dirt basement of a hotel. I had tried to light a barrel (桶) of paint but couldn't really get a good fire going. The smoke got pretty bad, though, and when I made my exit, a crowd and the police were there to greet me. The policemen took my matches and drove me home.Mom and Dad were occupied/busy in the garden and Dad told the police to keep me, and they did! I had a tour of the prison before Mom rescued me. 1 hadn't turned 5 yet.As I entered kindergarten, the serious cold began to set in. Would it surprise you to know that I soon left part of my tongue on a metal handrail(栏杆) at school?As for Leonhard Seppala, famous as a dog sledder (驾雪橇者), I think I knew him well because I was taken for a ride with his white dog team one Sunday. At the time I didn't realize what a superstar he was, but I do remember the ride well. I was wrapped heavily and well sheltered (保护) from the freezing and blowing weather.In 1950, we moved back to Coeur d'Alene, but we got one more Alaskan adventure when Leonhard invited us eight years later by paying a visit to Idaho to attend a gathering of former neighbors of Alaska.25. What can be inferred about the author's family?A. His father was a cruel man.B. His parents didn't love him.C. His mother didn't have any jobs.D. His parents used to be very busy.26. What happened when the author was 4?A. He learned to smoke.B. He was locked in a basement.C. He was arrested（拘捕） by the police.D. He nearly caused a fire accident.27. Which of the following is true?A. Leonhard was good at driving dog sleds.B. The author spent his whole childhood in Alaska.C. Leonhard often visited the author's family after 1950.D. The author suffered a lot while taking the dog sled in Alaska.28. What is the author's purpose of writing the text?A. To describe the extreme weather of Alaska.B. To look back on his childhood with adventures.C. To express how much he misses Leonhard.D. To show off his pride in making trouble.CHow fit are your teeth? Are you lazy about brushing them? Never fear: An inventor is on the case. An electric toothbrush senses how long and how well you brush, and it lets you track（跟踪） your performance on your phone.The Kolibree toothbrush was exhibited at the International Consumer Electronics Show in Las Vegas this week. It senses how it is moved and can send the information to an Android phone or iPhone via a Bluetooth wireless connection.The toothbrush will be able to teach you to brush right (don’t forget the insides of the teeth!) and make sure you’re brushing long enough. “It’s kind of like having a dentist actually watch your brushing on a day-to-day basis,” says Thomas Serval, the French inventor.The toothbrush will also be able to talk to other applications on your phone, so developers could, for example, create a game controlled by your toothbrush. You could score points for beating monsters among your teeth. “We try to make it s mart and fun,” Serval says.Serval says he was inspired by his experience as a father. He would come home from work and ask his kids if they had brushed their teeth. They said “yes,” but Servalwould find their toothbrush heads dry. He decided he needed a brush that really told him how well his children brushed.The company says the Kolibree will go on sale this summer, from $99 to $199, and the U.S. is the first target market.29. All of the following statements are wrong except ____________.A.It can t rack users’ school performance.B. It can sense how users brush their teeth.C. It can check users’ fear of seeing a dentist.D. It can help users find their phones.30. What can we learn from Serval’s words in Paragraph 3?A. You will find it enjoyable to see a dentist.B. You should see your dentist on a day-to –day basis.C. You’d like a dentist to watch you brush your teeth every day.D. You can brush with the Kolibree as if guided by a dentist.31. What can we infer about Serval’s children?A. They were unwilling to brush their teethB. They often failed to clean their toothbrushes.C. They preferred to use a toothbrush with a dry head.D. They liked brushing their teeth after Serval came home.DYou are the collector in the gallery of your life. You collect. You might not mean to but you do. One out of three people collects tangible things such as cats, photos and noisy toys.These are among some 40 collections that are being shown at “The Museum Of”—the first of several new museums which, over the next two years, will exhibit the objects accumulated（积累）by unknown collectors. In doing so, they will promote（推动）a popular culture of museums, not what museums normally represent(代表).Some of the collections are fairly common—records, model houses. Others are strangely beautiful—branches that have fallen from tree, for example. But they allreveal （显露）a lot of things: ask someone what they collect and their answers willtell you who they are.Others on the way include “The museum of Collectors” and “The Museum of Me.”These new ones, it is hoped, will build on the success of “The Museum Of.” The thinkersbehind the project want to explore why people collect, and what it means to do so.
