Rose, a neat, well-dressed, dark-haired young woman carries out her work at an office in a business park near Cambridge and spends hours studying pictures of children being abused (虐待). She watches the images again and again, looking for the tiniest details that might deliver a young victim from hell. They might be as small as the titles of books on a table, the action of making the bed or the images on the posters on the wall-anything that might provide a clue to the place where the child is suffering and might finally lead the police to the abuser.How can Rose decide to do such work? And all that for a salary of less than $23.000 a year? She said her motivation in joining the w ork was to protect the public. “When I first started this job, there was anger at the beginning. But when you see what the children have to endure, you know someone has to be there to protect them.

Isn’t it clear that compared wit h our glorious selves, kids these days are self-absorbed social network addicts?However, this summer, my impression of today’s kids has been restored by the story of Rachel Beckwith. She could teach my generation a great deal about maturity and unselfishness —even though she’s just 9 years old, or was when she died on July 23.At age 5, Rachel had her long hair short off and sent to Locks of Love, which uses hair donations to make artificial hair for children who have lost their own hair because of cancer or other diseases. After that, Rachel announced that she would grow her hair long again and donate it again. And that’s what she did.Then when she was 8 years old, her church began raising money to build wells in Africa through an organization called charity: water. Rachel was astonished when she learned that other children had no clean water, so she skipped her ninth birthday party. Rachel set up a birthday page on the charity: water website with a target of $300. Instead of presents, she asked her friends to donate $9 each to charity: water. Finally Rachel raised only $220 — which had left her just a bit disappointed.Then, on July 20, a serious traffic accident left Rachel critically injured. Church members and friends, seeking some way of showing suppo rt, began donating on Rachel’s birthday page —/Rachel — and donations reached her $300 goal, and kept rising.But Rachel couldn’t hear that she had raised beyond the $47,544 that the singer Justin Bieber had raised for charity: water on hi s 17th birthday. “I think Rachel would have been overjoyed for she secretly had a crush on (迷恋) him,” Rachel’s mom said.When it was clear that Rachel would never regain consciousness, the family decided to remove the life support system. Her parents donated her hair for the final time to Locks of Love, and her organs to other children.Word about Rachel’s last fund-raising spread. Contributions poured in, often in $9 each. The total donations soon topped $100,000, then $300,000.This is a story not just of one girl, but of a young generation of outstanding problem-solversworking creatively.8. What does the author think of today’s kids after he knew the story of Rachel Beckwith?A. They can get problems settled effectively.B. They are unselfish as grown-ups.C. They are good at social network.D. They have narrow minds and care about nothing.9. Why did each of Rachel’s friends donate $9 to charity: water?A. Because she began to raise money from her ninth birthday.B. Because she set up her birthday page on June 9th.C. Because she had asked them to do that.D. Because she died at the age of 9 and they wanted to honor her.10. Why was the singer Justin Bieber mentioned in the text?A. Rachel collected more than him who she admired.B. He had donated on R achel’s page on his 17th birthday.C. Rachel would have been overjoyed for his donation.D. Rachel’s mom said she secretly had a crush on him.11. What does the text mainly talk about?A. Rachel’s hair donations.B. A lesson from Rachel.C. The author’s impression of today’s kidsD. A kind girl, Rachel.DEvery year, billions of kilograms of fresh produce are wasted in the United States. Meanwhile, millions of poor Americans go hungry, without access to healthy and affordable meals. Evan Lutz, CEO and founder of Hungry Harvest, was inspired to act after seeing extreme poverty in areas of Baltimore. Maryland. He wants to reduce the so-called food desert in that area. His work is to make sure the food goes to waste and no person is ever hungry in America. And he combines that goal with a love for business.Hungry Harvest is a business which collects and sells fruits and vegetables that most food companies will throw away. Everything doesn’t grow the same way on a farm. But all that is too big or too small gets thrown out. That is why everything in a grocery store looks similar. Hungry Harvest will box those imperfect ones and deliver them to customers once a week.For every purchase, Hungry Harvest delivers healthy food to people in need. Hungry Harvesthas recovered 300,000 pounds of produce to date and provided 100,000 pounds to those in need.Lutz established Hungry Harvest in 2014. Its success depends on team work. Every week on Monday or Tuesday they will decide what will go into the next week’s b ox by calling up packing houses and wholesalers to see what they will normally throw away that week. They then place the order. The last step is to send goods to customers.In January 2016, Lutz appeared on the American business competition television show “Shark Tank” and got even more than he expected: $100,000. Lutz is using the money to expand. Actually, more than six billion pounds are wasted each year due to “ugly” surface. Hungry Harvest is on the way to saving more food from going to waste and feeding hungry families.12. What do the underlined words “food desert” mean?A. Food that grows in the desert.B. A lack of fresh and healthy food.C. The desert where food can grow.D. The poor areas in Baltimore.13. The food delivered by Hungry Harvest is ______________.A. popular with local fruit farmersB. easy to be found in grocery storesC. healthy and available to hungry peopleD. fresh but hard to keep for food companies14. Which of the following words can be used to describe Evan Lutz?A. strong-willed and smartB. kind-hearted and creativeC. warm-hearted and strictD. open-minded and humorous15. Who will not benefit from Evan Lutz’s business?A. Hungry HarvestB. Hungry familiesC. Fruit farmersD. Food companies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，选项中有两项为多余选项。

第Ⅰ卷阅读题甲必考题一、现代文阅读（9分，每小题3分）阅读下面的文字，完成1～3题。

礼之“仪”“义”的纠结除了“礼义之邦”“礼仪之邦”，文献中也经常出现“礼义之乡”“礼义之国”“礼义之朝”“礼仪之国”等概念。

传统中国，随着时代的发展和社会共同体的需要，礼越来越变得丰富多彩起来。

其间，既有文献解说的积淀充盈，也有典章制度的应时制作，更有身体力行的规范引导。

在此文化氛围之下，三礼（《周礼》《仪礼》《礼记》）、四礼（冠、婚、丧、祭）、五礼（吉、凶、军、宾、嘉）纷然而起，礼仪、礼制、礼俗竞相杂陈，守礼、行礼、变礼与时变化，等等。

究其归趣，清代大儒顾炎武所谓“礼者，本于人心之节文，以为自治治人之具”，可谓一语破的。

然而，自先秦以来，关于礼之义与仪的判别，则一直或显或隐地纠结着人们的思维。

如公元前537年，鲁昭公“如晋，自郊劳至于赠贿，无失礼”。

对此，晋侯以为他“善于礼”。

然而，女叔齐却有不同的看法，认为鲁昭公不知礼。

晋侯问其故，女叔齐回答：“是仪也，不可谓礼。

”那么，什么是礼呢？他解释说：“礼，所以守其国，行其政令，无失其民者也。

”而反观鲁国现状，则与礼之要求相去甚远。

所以女叔齐不无遗憾地感慨道：“礼之本末，将于此乎在，而屑屑焉习仪以亟。

言善于礼，不亦远乎！”《礼记》中也强调：“礼之所尊，尊其义也。

失其义，陈其数，祝史之事也。

故其数可陈也，其义难知也。

知其义而敬守之，天子之所以治天下也。

天地合，而后万物兴焉。

”对于礼教大为痛恨的吴虞，通过梳理前人有关的礼论，也曾感慨：“夫谈法律者，不贵识其条文，而贵明其所以立法之意；言礼制者，不在辨其仪节，而在知其所以制礼之心。

”柳诒徵先生则强调：“以史言史者之未识史原，坐以仪为礼也。

第Ⅰ卷阅读（70 分）一、论述文阅读（本大题 3 小题，每小题 3 分，共9 分）阅读下面三篇短文，完成1～3 题。

（9 分）（一）鲁迅说过：“悲剧将人生的有价值的东西毁灭给人看。

”这种毁灭是抗争、拼搏以后的毁灭，抗争与拼搏体现了人的一种精神。

古希腊神话中普罗米修斯为了人类从天上盗取火种，触怒了主神宙斯，被锁在高加索山崖上，每日遭神鹰啄食肝脏，但普罗米修斯毫不屈服，最后坠入深渊。

罗丹的大理石雕塑《马身人首》中，人臂绝望地扑向一个它所抓不到的目标，而马足则陷于尘土不能自拔，表现出人性与兽性的冲突，象征着灵与肉的斗争，具有强烈的悲剧性。

可以说，没有抗争就没有悲剧，冲突、抗争与毁灭是构成悲剧的三个主要因素。

悲剧的审美价值的载体只能是文学艺术。

因为人生有价值的东西、美好事物的毁灭是令人伤悲的，因此现实中的悲剧不能作为直接的审美对象来欣赏，否则人就是泯灭了人性的人了。

现实中的悲剧只能激起人的同情、义愤，迫使人采取严肃的伦理态度和实践行动。

民主革命时期，在演出歌剧《白毛女》的过程中，曾多次出现扮演地主黄世仁的演员被打甚至险遭枪击的事件，这是人们以实际的道德评价代替了审美活动。

现实的悲剧只在客观上具有悲剧的审美性质，它们必须以文学艺术的形式表现出来，才能成为欣赏的对象，美学上所谓的“以悲为美”才能实现。

(摘编自王晓旭《美的奥秘》) 1．下列各项中，其性质不属于原文所论悲剧的一项是（3 分）A．中国远征军赴缅甸对日作战局势节节败退，戴安澜将军在带领军队向缅北野人山撤退时腹部中弹，他坚持指挥军队抗战突围，最终伤势恶化，以身殉国。

AHe is both a great director and a great animator (卡通片制作者). He is Japan’s Walt Disney.Hayao Miyazaki, the 72-year-old Japanese master of fantasy animation (奇幻动画), one of the most respected animation directors in the world, announced his retirement on September 6. Here are some key words about his films.Good and evil (邪恶)Miyazaki rarely tells stories in simple good and evil. The worlds he creates tend to be complex (复杂的) and unclear. The bad figures often don’t seem so bad once you get to know them. Miyazaki has explained that the lack of clear good and evil is because he sees the 21st century as a complex time, in which old ideas need to be re-examined, even in children’s films.ChildrenThe heroes in Miyazaki’s films are usually children or tee ns,more often young girls. Sometimes they can see the spirit world; they are curious and friendly, even to strange creatures. The stories often deal with growing up.Sky and waterTwo of Miyazaki’s great loves are the sky and water, and he uses them in re lated ways. Flight is a forever theme — Miyazaki has never done a film without flying of some kind. His imagination seems to fly and leave behind the pull of gravity (重力), a force and control that he feels a bound (束缚) from setting him free.Water is another way for Miyazaki to fight gravity. In his films he likes the unexpected floods with crystal-clear water, and objects floating on the surface seem to be supported by magic.PeaceMiyazaki’s negative view of the war goes far more than surface deep. Violence is usually seen as wrong and painful, and Miyazaki’s heroes are often peacemakers.1. What can we know about good and evil from Miyazaki’s films?A. The figures cannot be simply judged as good or evil.B. He uses his films to show good finally defeats evil.C. The complex time tends to turn good into evil.D. Children should learn to clearly tell good from evil.2. According to the article, children in Miyazaki’s films are ______.A. all little teen-aged girlsB. always able to see spiritsC. curious trouble makersD. kind to people and creatures3. Miyazaki’s love for flight may come from ______.A. the relation between sky and waterB. his hate for gravity since his childhoodC. his desire to be free from gravityD. his love for water that can flood the world4. In Miyazaki’s films w e may NOT see ______.A. the appealing castle in the skyB. children with the problems of growing upC. objects magically floating on the waterD. a world left in ruins in the end【答案】1. A 2. D 3. C 4. D【解析】本文前两段主要介绍Miyazaki和退休的消息；后面几段主要介绍了他电影中常用到的一些主题。

AYOUR mom might cook a bowl of noodles for you on your birthday. But in the US, a mom makes a cupcake for her children on their birthday.Cupcakes are small, round cakes topped with frosting (糖霜). It has been an American tradition that moms bring cupcakes to the classroom to celebrate their child’s birthday. But recently some doctors have called for this to be banned. They believe cupcakes contribute to child obesity. Despite their good intentions, however, some people believe that experts are interfering (妨碍) with American culture. The cupcake is seen as American as apple pie —only prettier.According to Marion Nestle, a professor of nutrition at New York University, the cupcake is the most democratic (民主的) of desserts. As they are small enough for one person, you don’t have to share your cupcake with anyone —it’s all yours. They are also all of the same size, so there can’t be any cries of “she got the bigger piece!”Each bite can taste different depending on how much icing you have. It is a lesson in self-determination. Some people eat only a little of the frosting every time, others have it all in just one bite.In recent years, eating a cupcake has become as trendy as having a cup of Starbucks coffee.Democratic presidential candidate Hillary Clinton jokingly promised on a talk show that if she was elected president, she would give everyone a cupcake on her birthday. Ruth Reichl, editor-in-chief of Gourmet magazine, explains that the rise of the cupcake is very much about going back to American national identity in food, which is all about comfort. “People want to think about when they and their country were innocent,” she sai d.1.

A mom makes a cupcake for her children on their birthday and brings it to the classroomD. parents go travelling with their children on their birthday2. Which of the following is Not true according to Marion Nestle?A. The cupcake is more democratic than any other deserts in the US.B. The cupcake is too small to share with others.C. The sizes of cupcakes are the same so it’s equal to everyone.D. Cupcakes will lead to child obesity so they should be banned.3. Why did the writer mention Hillary Clinton and Ruth Reichl?A. To arouse the readers’ attention.B. To show that cupcakes are becoming a popular to show kindness and comfort.C. To make a comparison between them.D. To give readers a general idea of cupcakes.BI was never very neat, while my roommate Kate was extremely organized. Each of her objects had its place, but mine always hid somewhere. She even labeled (贴标签) everything. I always looked for everything. Over time, Kate got nearer and I got messier. She would push my dirty clothing over, and I would lay my books on her tidy desk. We both got tired of each other.War broke out one evening. Kate came into the room. Soon, I heard her screaming, "Take your shoes away! Why under my bed!" Deafened, I saw my shoes flying at me. I jumped to my feet and started yelling. She yelled back louder.The room was filled with anger. We could not have stayed together for a single minute but for a phone call. Kate answered it. From her end of the conversation, I could tell right away her grandma was seriously ill. When she hung up, she quickly crawled (爬) under her covers, sobbing.Obviously, that was something she should not go through alone. All of a sudden, a warm feeling of sympathy rose up in my heart. Slowly, I collected the pencils, took back the books, made my bed, cleaned the socks and swept the floor, even on her side. I got so into my work that I even didn't notice Kate had sat up. She was watching, her tears dried and her expression one of disbelief. Then, she reached out her hands to grasp mine. I looked up into her eyes. She smiled at me. "Thanks."Kate and I stayed roommates for the rest of the year. We didn't always agree, but we learned the key to livingtogether: giving in cleaning up and holding on.4. What made Kate angry one evening?A. She couldn't find her books.B. She heard the author shouting loud.C. She got the news that her grandma was ill.D. She saw the author's shoes beneath her bed.5.

How to Be OrganizedD. Learning to Be RoommatesCAre we getting more stupid? According to Gerald Crabtree, a scientist at Stanford University in the US, we are. You may not want to hear this, but Crabtree believes that human intelligence reached its peak more than 2,000 years ago and ever since then has been going downhill. “If an average Greek from 1,000 BC were transported to modern times, he or she w ould be one of the brightest among us,” Crabtree told The Guardian.At the heart of Crabtree’s thinking is a simple idea. In the past, intelligence was critical forsurvival when our ancestors had to avoid dangerous animals and hunt for food. The difference ofbeing smart or stupid is often life or death. However, after the spread of agriculture, when ourancestors began to live in dense ( 稠密的）farming communities, the need to keep theirintelligence in peak condition gradually reduced. This is not hard to understand. Most of the time,pressure is what keeps us going – you need the pressure from your teachers to finish yourhomework; the pressure of looking pretty prompts(促使) you to lose weight when summercomes. And the same is also true of our intelligence – if we think less, we become less smart.These mutations(变) are harmful to our intelligence and they were all developed in the past 3,000years. The other evidence that Crabtree holds is in our genes. He found that among the 2,000 to5,000 genes that we have that determine human intelligence , there are two or more mutations ineach of us. However, Crabtree’s theory has been criticized by some who say that early humansmay have better hunting and surviving abilities, but people today have developed a more diverseintelligence. For example, spearing a tiger doesn’t necessarily require more brainpower thanplaying chess or writing a poem. Moreover, the power of modern education means a lot morepeople have the opportunity to learn nowadays. “You wouldn’t get Stephen Hawking 2,000 years ago. He just wouldn’t exist,” Thomas Hills of the University of Warwick, UK, told Live Science. “But now we have people of his intellectual capacity doing things and making insights(洞察力) that we would never have achieved in our environment of evolutionary adaptation.”8. What is Crabtree’s recent finding according to the article?A. The Greeks from 1,000 BC could have been the smartest in human history.B. Our ancient ancestors had no better surviving abilities than we do nowadays.C. Humans have been getting steadily more intelligent since the invention of farming.D. Mutations in genes that decide human intelligence have affected the development of intelligence.9. According to Crabtree, ancient humans _______.A. had many more genes that determine human intelligenceB. were forced to be smart due to natural selection pressuresC. relied more on group intelligence than individual intelligenceD. developed a diverse intelligence to adapt to the hard realities10. Som e argue that Crabtree’s theory is false because they think _______.A. people today are under much more pressure than early humansB. it’s ridiculous to compare a hunter’s and a poet’s intelligenceC. modern education is far more advanced than ancient educationD. human intelligence nowadays is different from that of the distant past11. What is Thomas Hills’ attitude toward Crabtree’s theory?A. SupportiveB. UnfavorableC. WorriedD. ConfusedDPicture the scene: You come home after work feeling too exhausted to cook –only to find a delicious meal worthy of a Michelin-starred restaurant waiting for you. It sounds like a fantasy, but it could be about to come true thanks to a robot chef developed by British scientists.Those scientists have come up with a set of robotic arms so smart that they are capable of cooking meals all by themselves. The device will be sold from as early as 2017 as part of a purpose-built high-tech kitchen.Scientists at Moley Robotics spent almost 18 years developing the hands. According to its creators, the arms can chop, stir, whisk and baste well enough to recreate almost anything you would care to eat, whether it is a simple home-cooked supper, or a complicated creation designed by a world-class chef. The hands move a little slowly, hovering strangely above the work surface whenever they are not busy, but they imitate human movements closely enough that they can do things such as wiping a spoon on the edge of a pan to prevent drips.Mr Oleynik, who is leading the project, said, “All the things which are possible with the hand are possible here. There is no limitation. A lot of people want to go to Michelin-starred restaurants, but they are quite expensive and may be quite far from the home. This is an opportunity for people to enjoy very good food, and for a reasonable price. ”The only cuisine that is off the robot’s menu at the moment is sushi, which requires extremely steady pressure and nimble（敏捷的；敏感的）fingers to make, but the team plan to conquer that as well by the timeit goes on sale.12. People go to Michelin-starred restaurants in order to_________.A. appreciate car tiresB. enjoy delicious mealsC. see the new robot chefsD. escape from work13. What does the underlined word “they” in Paragraph 2 refer to?A. British scientistsB. The robot chef’s armsC. Cooks at restaurantsD. Household wives14. Which kind of food CAN’T the robot chef cook at present?A. BreadB. BeefC. SushiD. Sandwich15. What can we infer from the passage?A. Hands of a robot chef can perform exactly like a cook.B. Robot chefs are available at shopping malls.C. Michelin-starred restaurants are suitable for many people.D. It is uncertain when the robot can cook all kinds of food.Ⅱ七选五（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。

AHe is both a great director and a great animator (卡通片制作者). He is Japan’s Walt Disney.Hayao Miyazaki, the 72-year-old Japanese master of fantasy animation (奇幻动画), one of the most respected animation directors in the world, announced hisretirement on September 6. Here are some key words about his films.Good and evil (邪恶)Miyazaki rarely tells stories in simple good and evil. The worlds he createstend to be complex (复杂的) and unclear. The bad figures often don’t seem so bad once you get to know them. Miyazaki has explained that the lack of clear good andevil is because he sees the 21st century as a complex time, in which old ideas need to be re-examined, even in children’s films.ChildrenThe heroes in Miyazaki’s films are usually children or teens, more often young girls. Sometimes they can see the spirit world; they are curious and friendly, even to strange creatures. The stories often deal with growing up.Sky and waterTwo of Miyazaki’s great loves are the sky and water, and he uses them in related ways. Flight is a forever theme — Miyazaki has never done a film without flyingof some kind. His imagination seems to fly and leave behind the pull of gravity (重力), a force and control that he feels a bound (束缚) from setting him free.Water is another way for Miyazaki to fight gravity. In his films he likes theunexpected floods with crystal-clear water, and objects floating on the surface seem to be supported by magic.PeaceMiyazaki’s negative view of the war goes far more than surface deep. Violence is usually seen as wrong and painful, and Miyazaki’s heroes are often peacemakers.1. What can we know about good and evil from Miyaza ki’s films?A. The figures cannot be simply judged as good or evil.B. He uses his films to show good finally defeats evil.C. The complex time tends to turn good into evil.D. Children should learn to clearly tell good from evil.2. According to the artic le, children in Miyazaki’s films are ______.A. all little teen-aged girlsB. always able to see spiritsC. curious trouble makersD. kind to people and creatures3. Miyazaki’s love for flight may come from ______.A. the relation between sky and waterB. his hate for gravity since his childhoodC. his desire to be free from gravityD. his love for water that can flood the world4. In Miyazaki’s films we may NOT see ______.A. the appealing castle in the skyB. children with the problems of growing upC. objects magically floating on the waterD. a world left in ruins in the end【答案】1. A 2. D 3. C 4. D【解析】本文前两段主要介绍Miyazaki和退休的消息；后面几段主要介绍了他电影中常用到的一些主题。

ANational RankingsBest High SchoolsThe U.S. News rankings include data on more than 22,000 public high schools in 50 states and the District of Columbia. Schools were awarded gold, silver or bronze medals based on their performance on state assessments and how well they prepare students for college.About the AwardsGold --- Top 500 Schools based on highest college readiness.Silver --- High-performing schools based on lower college readiness.Bronze --- High-performing schools based on state exam performance, listed alphabetically.Award DistributionGold 2.4%Silver 10.3%Bronze 16.8%No Medal 70.5%HOWWeDetermine the AwardsSTEP 1 Students perform better than expected in their state.We looked at reading and math results for students on each state’s proficiency (水平) tests and then factored in the percentage of economically disadvantaged students, who tend to score lower.STEP 2 Disadvantaged students perform better than state average.We compared each school’s math and reading proficiency rates for disadvantaged students --- black, Hispanic and low-income --- with the statewide results for these student groups and then selected schools that were performing better than their state averages.STEP 3 Student graduation rates meet or are greater than a national standard.We left out schools from consideration if their graduation rates were lower than 75 percent --- astarting point that is higher than a federal law that requires states to give extra resources to schools below 67 percent.STEP 4 Students are prepared for college-level coursework.We calculated a College Readiness Index, which is based on the school’s AP participation rate and how well the students did on those tests. Tiebeakers were used to determine ranks of schools that achieved the same College Readiness Index.1. What plays an important part in winning medals?A. Schools’ intention.B. College assessment.C. Government’s judgmentD. State evaluation.2. How much do schools winning medals account for?A. 16.8％.B. 27.1％.C. 29.5％.D. 70.5％.3. Which school can get the awards?A. The school whose students do better than demanded.B. The school whose disadvantaged students perform averagely.C. The school whose graduation rates were lower than 67 percent.D. The school whose students have a knowledge of College Readiness Index.BThe Right Thing“Hi, Mrs. Grady,” said Mark when their neighbor opened her door. “Would you like us to shovel your sidewalk and driveway?” Shoveling was Jamie’s idea, a way to earn enough money for the new Ocean Kingdom video game that came out the next day.Mrs.Grady was happy, “That would be w onderful, boys. I think the job is getting to be too much for me.”“It will cost 10 dollars,” Jamie said. “If that’s OK,”Mark added.“Oh dear,” Mrs. Grady said disappointedly, “I haven’t been able to get to the bank. I can offer homemade cookies, b ut I realize that’s not what you had in mind.”Mark was going to say that Mrs. Grady could pay them another time, but Jamie cut him off. “We’ll come back later.”Mrs. Grady doesn’t look like the person who’d come to his rescue last summer when Mr. Dunn’s dog, Goldie, had just wanted to play, but Mark didn’t feel comfortable around big dogs. He wanted to call for help, but his tongue seemed locked behind his teeth. Then Mrs. Grady’s front door had flown open. She must have seen him from across t he street. “Hold on, Mark. I’m coming!” “Goldie” she’d called. As soon as Goldie had turned her head, Mrs. Grady had slipped between Mark and the dog. She wasn’t much taller than Mark, but she’d stood firm as a rock in front of him. “Goldie, go home!” Then she’d swept her broom to hurry the dogalong.“Get away!” Goldie had obeyed.When Mark showed thanks to Mrs.Grady, Mrs. Grady laughed.“It was nothing. Good neighbors watch out for each other, don’t they?”And now Mrs. Grady needed Mark as much as he’d needed her last summer. He smiled and waved at Mrs. Grady, then his shovel deep into the snow.“Hey!” Jamie shouted. “What are you doing?”Mark couldn’t explain about Goldie and watching out for neighbors.“I like Mrs. Grady’s cookies,”he said.4. Why did Jamie and Mark plan to clear the snow for Mrs.Grady at first?A. To help the lady.B. To earn pocket money.C. To do volunteer work.D. To visit New Kingdom.5. What was the most probable reason why Mrs. Grady couldn’t pay them?A. S he didn’t have enough cash.B. S he couldn’t find the bank.C. She thought it was worthless.D. S he couldn’t afford it.6. According to the story, which of the following word CAN NOT be used to describeMrs.Grady?A. Positive.B. Helpful.C. Brave.D. Hopeful.7. Which of the following proverb can best summarize the story?A. A penny saved is a penny earned.B. Kindness is repaid with kindness.C. A clear conscience.D. Actions speak louder than work.CImagine this scene: it’s blowing outside, and you snuggle (蜷伏) up on the sofa under a warm quilt, chatting and recalling with your closest friends.That content, cosy feeling has a name in Danish --- hygge. And, as Denmark recently won the title of “the happiest country in the world”, the concept of hygge is known to more and more people interested in finding ways to understand this concept.Hygge --- originally from a Norwegian word meaning well-being --- doesn’t have an exact equivalent (等同物) in English. It’s often translated as coziness, or as blogger Anna West told the BBC, “coziness of the soul”. But, as professor Maren Spark explains, “Hygge was never meant to be translated. It was meant to be felt.”Basically, hygge involves creating a warm, cosy atmosphere and enjoying it with your loved ones. Danish winters are long and dark and so achieving hygge is particularly relevant during this season. A typical hygge activity during winter could be enjoying delicious homemade food and light-hearted conversation with friends --- preferably in the warm glow of candlelight, or maybe sipping a glass of wine in the hot tub after a day spent skiing.However, hygge isn’t only limited to the cold winter months --- it can also describe that warm, fuzzy feeling you get after a walk through a forest with friends on summer’s day or a family barbecue in the park. Hygge is meant to be shared.8. Why does the author ask the readers to imagine the scene in thefirst paragraph?A. Help the readers to calm down.B. Introduce the topic of the passage.C. Present the main idea of the passage.D. Remind the readers of their past memories.9. What do the underlined words by Maren Spark mean?A. The translation of the word “hygge” is not good enough.B. Only Danish speakers know what “hygge” means.C. “Hygge” is easy to translate but hard to feel.D. We can get the true meaning of “hygge” by feeling it.10. Which of the following can be best described as a “hygge” activity?A. Skiing in the cold winter months.B. Living through long dark winters.C. Taking afternoon tea with friends.D. Walking alone in the forest.11. What is the main purpose of the author?A. To explain.B. To persuade.C. To comment.D. To advertise.DIn the mid-2000s, Waze Mobile co-founder Ehud Shabtai received a cutting-edge (尖端的) gift from his girlfriend: a GPS. The expensive gift was supposed to be helpful. But straight out of the box, it was already out of date.Shabtai, a coding enthusiast,had an immediate reaction to reinvent. Shabtai’s solution? To build an app. With 50 million monthly active users globally and nearly 400,000 superusers who function much like Wikipedia volunteer editors (editing maps rather than words), Waze Mobile caught the eye of Google as a revolutionary approach to navigation(导航).Acquired by Google in 2013, Waze’s value mainly lies in its high rate of user involvement. Unlike traditional navigation apps that simply show directions, Waze asks its users to report accidents and other road conditions in real time, so other users can avoid the traffic by using an alternative route.The goal behind Waze’s approach is an ambitious one: not just avoid traffic, but end it altogether. Waze is finding new ways to put its loyal and active user base to use to make that vision a reality, including a plan to make carpooling (拼车) cool.To be sure, traffic jams are troubling people all over the world. Waze has been quietly ahead of the game for some time. In 2013, when Waze was just a small digital-mapping business with limited resources, it had something Google Maps and oth er competitors didn’t: richer GPS guidance thanks to its stream of live traffic reports from users.These users were the basis of Shabtai’s plan to solve for his GPS device’s “silent” hardware: he grounded the app in software that could be perpetually updated by users, anywhere and anytime.Waze Carpool is going straight to the heart of traffic jams, trying to get more drivers off the road and into carpools. The app has already connected tens of thousands of rideseekers with drivers willing to ferry them along a shared route, and that trend could be the answer to a traffic-free future.12. What did Shabtai do when he found his girlfriend’s gift out of date?A. He improved it.B. He took it apart.C. He put it away.D. He used it anyway.13. What sets Waze Mobile apart from traditional navigation apps?A. It has the most users.B. It can indicate directions.C. It reports road conditions in real time.D. Most users help edit its words.14. What does the underlined word in paragraph 6 probably mean?A. Difficulty.B. Carefully.C. Greatly.D. Constantly.15. What is mainly talked about in the text?A. The rise of carpooling.B. An advanced navigation app.C. The development of Google.D. Traffic problems in the world.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。
