It is a world-famous castleBGrandma Moses is among the most famous twentieth-century painters of the United States,yet she did not start painting until she was in her late seventies.As she once said to herself:" I would never sit back in a rocking chair,waiting for someone to help me." No one could have had a more productive old age.She was born Anna Mary Robertson on a farm in New York State,one of five boys and five girls.At twelve she left home and was in domestic service until,at twenty-seven,she married Thomas Moses,the hired hand of one of her employers.They farmed most of their lives,first in Virginia and then in New York State,at Eagle Bridge.She had ten children,of whom five survived;her husband died in 1927.Grandma Moses painted a little as a child and made embroidery(刺绣) pictures as a hobby,but only changed to oils in old age because her hands had become too stiff(僵硬的) to sew and she wanted to keep busy and pass the time.Her pictures were first sold at the local drugstore and at a market and were soon noticed by a businessman who bought everything she painted.Three of the pictures exhibited(展览) in the Museum of Modern Art,and in 1940 she had her first exhibition in New York.Between the 1930's and her death,she produced some 2,000 pictures:careful and lively portrayals of the country life she had known for so long,with a wonderful sense of color and form."I think really hard till I think of something really pretty,and then I paint it" shesaid.24.According to the passage,Grandma Moses began to paint because she wanted to________.A.make herself beautiful B.keep activeC.earn more money D.become famous25.Grandma Moses spent most of her life________.A.nursing B.painting C.embroidering D.farming26.The underlined word “portrayals ”means________.A. descriptionsB. expressionsC. explanationsD. impressions 27.Which of the following would be the best title for the passage?A.Grandma Moses:Her Life and Pictures.B.The Children of Grandma Moses.C.Grandma Moses:The Best Painter.D.Grandma Moses and Her Exhibition.CWe all know what a brain is. A doctor will tell you that the brain is the organ of the bo dy in the head. It controls our body’s functions, movements, emotions and thoughts. But a brain can mean so much more.A brain can also simply be a smart person. If a person is called brainy, she is smart and intelligent. If a family has many children but one of them is super smart, you could say “She's the brains in the family.” And if you are the brains behind an organization, you are responsible for developing or organizing it.Brain trust is a group of experts who give advice. Word experts say the phrase “brain trust” became popular when Franklin D. Roosevelt first ran for president in 1932. Several professors gave him advice on social and political issues facing the U.S. These professors were called his “brain trust.”These ways we use the word “brain” all make sense. But other ways we use the word are not so easy to understand. For example, to understand the next brain expression, you first need to know the word “drain”. As a verb, to drain means toremove something by letting it flow away. So a brain drain may sound like a disease where the brain flows out the ears. But, a brain drain is when a country's most educated people leave their countries to live in another. The brains are, sort of, draining out of the country.However, if people are responsible for a great idea, you could say they brainstormed it. Here, brainstorm is not an act of weather. It is a process of thinking creatively about a complex topic. For example, business leaders may use brainstorming to create new products, and government leaders may brainstorm to solve problems.If people are brainwashed, it does not mean their brains are nice and clean. To brainwash means to make someone accept new beliefs by using repeated pressure in a forceful or tricky way. Keep in mind that brainwash is never used in a good way. 28.Why did Roosevelt successfully win the election according to the passage?A.Because he was the brain trust of Americans.B.Because he got his brain trust.C.Because he was smart at giving advice.D.Because word experts say he is “the brain trust”.29.According to the text, if you’re the CEO of Bai Du you can be called_______ .A.the organ of Bai Du B.the brain drain of Bai DuC.the brains behind Bai Du D.Bai Du’s brain trust30.Which of the following expressions is always used in an impolite way?A.Brainstorm B.Brain trust C.Brainwash D.Brain drain 31.What’s the main idea of this article?A.The origin of the word “brain”.B.The word “brain” and its stories.C.The brain is an important organ of the body.D.How to use your brain more effectively.DA Japanese telecom company has designed a robot that it says has emotions(情绪). But rather than run in fear from it, we've welcomed it into our homes: Pepper,the “emotional robot,” sold out within a minute of going o n sale.Created by Aldebaran Robotics and Japanese mobile giant SoftBank, Pepper went on sale to the general public in Japan June 20. It is “the first humanoid(类人的) robot designed to live with humans,” Aldebaran says on its website. Pepper costs about $1,600. And like all good mobile products, there’s a $120 per month data fee, as well as an $80 per month damage insurance fee. According to a news report, Pepper can pick up on human emotions and create his own using a “multi-layer neural(神经的) network.” Pepper’s touch sensors and cameras are said to influence its mood, which is displayed(展示) on the tablet-sized screen on its chest.Pepper will sigh when unhappy, and can go around your house recording your family's daily activity. Aldebaran says Pepper can feel “joy, surprise, anger, doubt and sadness,” but it doesn't say how strongly it can feel these emotions. What happens when Pepper is having a bad day? Will it, like many humans, become uncooperative? Will it ask for some time alone? What happens if it knows that its purpose in life is just to take part in small talk? Thankfully, Pepper is only about four feet tall, with roller balls instead of legs, so if it is angry with and even turns on its owners, you'll be safe if you can make it upstairs.Aldebaran says in reality, they're probably quite a few years away from artificial intelligence that could create real emotions. Aldebaran wasn't immediately able to tell when Pepper will be available(可得的) out of Japan, but additional sales are scheduled for July after the first 1,000 units sell out. SoftBank currently uses the robots in its stores as greeters, and it plans to offer Pepper to other stores in the future. Hopefully “boredom” is not an emotion Pepper can feel. 32.According to the author, Pepper ________.A.is very popular among customersB.can not only run but also show fearC.is going to be sold all over the worldD.can deal with many kinds of housework33.How much do you need to pay for Pepper’s data and damage insurance fee each year? A.80 dollars. B.120 dollars. C.1,440 dollars. D.2,400dollars.34.Pepper’s height and roller balls are mentioned to ________.A.introduce its appearance B.tell Pepper won’t get angryC.show that safety isn’t a big issue D.explain robots have strong emotions35.What can we infer from the last paragraph?A.Pepper cannot produce real emotions.B.Pepper can feel joy, surprise and boredom.C.Pepper will be sold in other countries next year.D.Pepper is being used as waiters in some restaurants.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。

AI never thought I would have a life-changing experience at Wal-Mart.Although my thoughts were only on speed, the checkout line I was standing in wasn’t moving as quickly as I wanted, and I glanced toward the cashier.T here stood a man in his seventies, wearing glasses and a nice smile. I thought, well, he’s an old guy!For the next few minutes I watched him. He greeted every customer before scanning the items. Sure, his words were the usual, “How’s it going?” But he did something different----he actually listened to people. Then he would respond to what they had said and engage them in brief conversation.I thought it was odd. I have grown accustomed to people asking me how I was doing simply out of robotic conversationa l habit. After a while, you don’t give any thought to the question and just mumble something back. I could say, “I just found out I have six months to live,” and someone would reply, “Have a great day!”But that wasn’t the end.He gave them the change, walked around the counter, and extended his right hand in an act of friendship. He looked the customers in the eyes. “I sure want to thank you for shopping here today,” he told them. “You have a great day. Bye-bye.”The looks on the faces of the customers were priceless. There were smiles and some sheepish grins. All had been touched by his simple gesture and in a place they never expected. They would gather their things and walk out, smiling.Of course, he did the same to me and I got to know his name, Marty.I had never walked away from that shop feeling like that.31. According to the writer, when common people ask you “How’s it going?”.A. they don’t really care what you may answerB. they are just practicing their conversation abilityC. they are inquiring about your private informationD. they don’t expect to hear any negative answers32. What was most customers’ reaction to Marty’s behaviors?A. They thought it worthless.B. They were in some way moved.C. They thought it awful and odd.D. They felt somewhat offended.33. What does the writer intend to express through the text?A. Our everyday life is always full of surprises.B. Most customers enjoy being treated this way.C. Being different is a good way of doing business.D. A little positive action can make a big difference.BJumping across citiesForget about expensive gyms; the new sport in cities isfree-running. Since it started in a Paris suburb around 1995,free-running has attracted lots of fans in cities around the world.Instead of walking normally, free-runners jump over or aroundanything ― cars, buildings, trees, or streetlights ― in their way.One of the sport’s inventors told our reporter how free-running started.It was boring where we lived. There was nothing for us to do after school. We had done playground games like football and basketball when we were kids but we wanted something new and exciting. We started learning how to jump and run between buildings ― and we loved it. Walking is a waste of time. Free-runners have to use their imaginations. Everything ― a tree, a streetlight ―is part of our outdoor gym. We’re like children because we have never stopped playing in the street.The sport’s website has lots of rules, for example, don’t break people’s windows, don’t jump on flowerbeds and don’t be rude to people who want you to stop. Safety is also very important. You must start with the easy moves ― you have to do thousands of small practice jumps before you try anything difficult. If you made only one mistake, you might hurt yourself badly.A local person said, “It’s good that young people have something to do. But when they jump off buildings like cats, they sometimes frighten other people.”Don’t try this at home: the basics of free-runningBlind Jump: a jump whe re you can’t see the landing spot.Tic-tac: run and put your foot on a small step, go forward and jump over the next thing.Basic Jump:run and jump, land on two feet while bending your knees. To finish roll into head-over-heels.Cat Jump: run towards a wall, put both hands on the top of the wall and jump through your arms.34. Free-running started __________.A. about twenty years agoB. with the help of schoolsC. in big cities of AmericaD. among famous sportsmen35. Free-runners shouldn’t ___________.A. use their imaginationsB. start with the easy movesC. jump on flowerbedsD. run between buildings36. According to the passage, free-running is a(n)__________sport.A. ancientB. expensiveC. safeD. exciting37. The purpose of this passage is to ___________.A. explain the importance of outdoor activitiesB. introduce some information about free-runningC. warn children not to join in dangerous sportsD. advise people to do more exercise at home firstCShopping is not as simple as you may think! There are all sorts of tricks at play each time we reach out for that particular brand of product on the shelf.Coloring, for example, varies according to what the producers are trying to sell. Health foods are packaged in greens, yellows or browns because we think of these as healthy colors. Ice cream packets are often blue and expensive goods, like chocolates, are gold or silver.When some kind of pain killer was brought out recently, researchers found that the colors turned the customers off because they made the product look weak and ineffective. Eventually, it came on the market in a dark blue and white package—blue because we think of it as safe, and white as calm.T he size of a product can attract a shopper. But quite often a bottle doesn’t contain as much as it appears to.It is believed that the better-known companies spend, on average, 70 percent of the total cost of the product itself on packaging!The mo st successful producers know that it’s not enough to have a good product. The founder of Pears soap, who for 25 years has used pretty little girls to promote (推销) their goods, came to the conclusion: “Any fool can make soap, but it takes a genius to sell it.”38. Which of the following may trick a shopper into buying a product according to the text?A. The cost of its package.B. The price of the product.C. The color of its package.D. The brand name of the product.39. The underlined part “the colors turned the customers off” (in Para.3) means that the colors _________.A. attracted the customers stronglyB. caused the customers to lose interestC. tricked the customers into shoppingD. had weak effects on the customers40. Which of the following is the key to the success in product sales?A. The way to promote goods.B. The discovery of a genius.C. The team to produce a good product.D. The brand name used by successful producers.41. Which of the following would be the best title for this text?A. Choice of Good ProductsB. Disadvantages of ProductsC. Effect of Packaging on ShoppingD. Brand Names and Shopping TricksDWhy do Americans struggle with watching their weight, while the French, who consume rich food, continue to stay thin? Now a research by Cornell University suggests how life style and decisions about eating may affect weight. Researchers concluded that the French tend to stop eating when they feel full. However, Americans tend to stop when their plate is empty or their favorite TV show is over.According to Dr. Joseph Mercola, a health expert, the French see eating as an important part of their life style. They enjoy food and therefore spend a fairly long time at the table, while Americans see eating as something to be squeezed between the other daily activities. Mercola believes Americans lose the ability to sense when they are actually full. So they keep eating long after the French would have stopped. In addition, he points out that Americans drive to huge supermarkets to buy canned and frozen foods for the week. The French, instead, tend to shop daily, walking to small shops and farmers’ markets whe re they have a choice of fresh fruits, vegetables, and eggs as well as high-quality meats for each meal.After a visit to the United States, Mireille Guiliano, author of French Women Don’t Get Fat, decided to write about the importance of knowing when to stop rather than suggesting how toavoid food. Today she continues to stay slim and rarely goes to the gym.In spite of all these differences, evidence shows that recent life style changes may be affecting French eating habits. Today the rate of obesity —or extreme overweight —among adults is only 6%. However, as American fast food gains acceptance and the young reject older traditions, the obesity rate among French children has reached 17% — and is growing.42. In what way are the French different from Americans according to Dr. Joseph Mercola?A. They go shopping at supermarkets more frequently.B. They squeeze eating between the other daily activities.C. They regard eating as a key part of their lifestyles.D. They usually eat too much canned and frozen food.43. This text is mainly the relationship between _________.A. Americans and the FrenchB. life style and obesity(肥胖)C. children and adultsD. fast food and overweight44. The text is mainly developed __________.A. by contrast(对比)B. by spaceC. by timeD. by importance45. Where does this text probably come from?A. A TV interviewB. A food advertisementC. A health reportD. A book review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。
