It’s quick, easy, and not cheap, but cheaper than buying a car the old way.The company has been working on the concept for the pasttwo years. Their 31 car vending machine was installed in Atlanta in 2013. But they’ve spent time improving the design, in order to take user experience to the next level. “Our new Vending Machine is a state-of-the-art, multi-story structure that delivers our customers’ cars by merely 32 a special coin,” said Carvana CEO Ernie Garcia.The machine consists of a five-story glass tower that can hold up to 20 cars at a time. The tower basically serves as a(n) 33 point for used cars that customers purchase through the website, enabling 34 pricing and eliminating delivery costs.Customers can access a long list of specifications, ratings, reviews, and lots of other details about the cars they’re interested in on the Carvana website. They even get 35 tours that point out every scratch on the body of the car. Once the car is chosen and paid for, the company usually delivers the car to the customer for a s e v e n-d a y t r i a l p e r i o d.T h i s u s u a l l y me a n s t h e d e l i v e r y c o s t s a r e w o r k e d i n t o t h e 36 of the vehicle.But with the Vending Machine, customers are able to go to pick u p their cars straight away. It’s a win-win 37 that allows Carvana to cut down on staff and overhead (间接费用), and save customers about $2,000 as well. According to the company, it also makes for a great 38experience – placing an oversized coin in a slot (硬币投币口) and watching their car roll down automatically.“Carvana’s 39 is to create a better way to buy a car, and this new Vending Machine will be a one-of-a-kind experience, 40 just how simple and easy we’ve made it to buy a car online,” Garcia said. He added the company plans to build more car vending machines in the future.III. Reading ComprehensionSection ADirections: For each blank in the following passage there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.Stay out of the Sun to Look YoungForget drinking countless glasses of water or getting your beauty sleep. The secret of looking young is simply to stay out of the sun. A study of hundreds of women has revealed that those who avoided the sun’s rays looked up to 20 years younger than they actually are.However, other supposed rules for a youthful complexion (肤色), from drinking lots of water to sleeping well and exercising regularly, failed to 41 the hands of time. Only keeping out of the sun, and wearing sunscreen when this wasn’t possible, made a 42 , the American Academy of Dermatology’s annual confer ence will hear today. The interesting 43 comes from a study of 231 women of all ages who were quizzed about their lives, including whether they were sun-lovers. When researchers from Massachusetts General Hospital in the US –commissioned by skincare firm Olay –guessed how old the women were, they found those who 44 in the sun tended to have aged more slowly.A lucky four had so few wrinkles and 45 spots, and such a fresh complexion, that they appeared to be a full two decades younger than they really were.Researcher Dr Alexa Kimball, a professor of dermatology (皮肤医学), said the 46 advice that we drink lots of water to stay healthy is actually a myth (谬见), and the body is ‘pretty good’ at judging how much we need.。

It's quick, easy, and not cheap, but cheaper than buying a car the old way.The company has been working on the concept for the past two years.Their1car vending machine was installed in Atlanta in 2013. But they've spent time improving the design, in order to take user experience to the next level. "Our new Vending Machine is a state-of-the-art, multi-story structure that delivers our customers'cars bymerely2 a special coin, "said Carvana CEO Ernie Garcia.The machine consists of a five﹣story glass tower that can hold up to 20cars at a time. The tower basically serves as a n3point for used cars that customers purchase through the website, enabling4pricing and eliminating delivery costs.Customers can access a long list of specifications, ratings, reviews, and lots of other details about the cars they're interested in on the Carvana website. They even get5tours that point out every scratch on the body of the car. Once the car is chosen and paid for, the company usually delivers the car to the customer for a seven﹣day trial period. This usually means the delivery costs are worked into the6of the vehicle.But with the Vending Machine, customers are able to go to pick up their cars straight away. It's a win-win7that allows Carvana to cut down on staff and overhead（间接费用） , and save customers about $2,000as well.

The secret of looking young is simply to stay out of the sun. A study of hundreds of women has revealed that those who avoided the sun's rays looked up to 20 years younger than they actually are.However, other supposed rules for a youthful complexion（肤色）, from drinking lots of water to sleeping well and exercising regularly, failed to1the hands of time. Only keeping out of the sun, and wearing sunscreen when this wasn't possible, madea2, the American Academy of Dermatology's annual conference will hear today. The interesting3comes from a study of 231 women of all ages who were quizzed about their lives, including whether they were sun﹣lovers. When researchers from Massachusetts General Hospital in the US﹣commissioned by skincare firm Olay﹣guessed how old the women were, they found those who4in the sun tended to have aged more slowly. A lucky four had so few wrinkles and5spots, and such a fresh complexion, that they appeared to be a full two decades younger than they really were.Researcher Dr Alexa Kimball, a professor of dermatology（皮肤医学） , saidthe6advice that we drink lots of water to stay healthy is actually a myth（谬见） , and the body is'pretty good'at judging how much we need.Previous research by the British Nutrition Foundation reacheda7conclusion. Experts there said：'Just drinking water for the sake of drinking water really has no effect on improving the appearance of skin. 'It isn't clear why the womenwho8well didn't have younger-looking skin. But it may be that the question they were asked was too9and didn't take into account their long-term sleep patterns.A second study, also by Olay, suggested that low﹣level day to day exposure to the sun is more ageing than10, intense exposure. Finally, DNA examination of tiny samples of the women's skin helped understand the11done by the sun. A gene called CDKN2A was more active in facial skin that is exposed to the elements than in samples taken from the bottoms. This gene was also more active in women who said they lovedthe12— and in those who looked older. Dr Kimball said CDKN2A activity isa13that a cell is'tired out'and urged women should protect their skin year round and not just when on a beach holiday.Dr Frauke Neuser, principal scientist at Olay, which has used the14to develop its latest face creams, said，"This research gives us a detailed picture of the effect of sun exposure on skin ageing and illustrate the importance of protection on a15basis.

And they are examples of the evolution of animation, which has brought unique new life to the film industry.Among the first American animated films was Light of the Moon, a silent movie produced in1911using silhouette （剪影） animation, where the characters are represented only as black silhouettes.The real breakthrough for American animation came with Steamboat Willie, created by Walt Disney and released in 1928. It was the first animated film to be accompanied by sound, and its main star, Mickey Mouse, became one of the most loveable and enduring animated characters ever created. Disney also created the first American full﹣length animated film, Snow White and the Seven Dwarfs. Released in 1937, it enjoyed worldwide box﹣office success.Disney's extremely careful attention to high﹣quality detail in the thousands of hand﹣painted drawings required at that time to make an animated film elevated this film technique to the level of a serious art form.Clay animation is a type of stop﹣motion animation using forms made of clay. Clay animation films have been produced in the United States since 1908. But this form of animation only won wide popular appeal in 1955with a short film called Gumbasia, created by Art Clokey.Computer﹣generated imagery, or CGI, brought animation to a new level of artistry andrealism. Used in film since the 1960s, CGI animation began to develop rapidly in the mid﹣1990s. Toy Story, released in 1995and created by Pixar and Disney Studios, was the first completely computer﹣generated animated feature film.In 2001, DreamWorks and Pacific Data Images released Shrek, the first computer﹣animated feature film to win an Oscar. Shrek returned in 2004 with his talking donkey, his princess bride Fiona and an army of fairy﹣tale characters in Shrek 2. Hugely popular, that film became the highest﹣grossing （票房最高的） animated film of all time.In addition to strictly animated movies, animation has been mixed into films showing live actors as well. Who can forget the terrifyingly real dinosaurs thundering through Steven Spielberg's Jurassic Park movies and the actors they chased Thanks to the powerful capabilities of today's computers and the unlimited imagination of American filmmakers, animation will be entertaining audiences worldwide for a long time to come.(1) The passage is mainly about the of animation.A. influenceB. popularityC. charactersD. development(2) Which film marked the beginning of the complete digital age of American animationA.

The program, which lasted from first grade through tenth grade, reduced arrests and use of health and mental health services as the students aged through adolescence and young adulthood, as researchers explained in a separate study.In the latest study, researchers looked at the"why"behind those previous findings. In looking at the data from nearly 900 students, the researchers found that about a third of the impact on future crime outcomes was due to the social and self﹣regulation skills the students learned from ages 6to 11.The academic skills that were taught as part of Fast Track turned out to have less of an impact on crime than did the soft skills, which are associated with emotional intelligence."The conclusion that we would make is that these soft skills should be emphasized even more in our education system and in our system of socializing children, "says Kenneth Dodge, a professor at Duke who was a principal investigator in this study as well as in the original Fast Track project. Parents should do all they can to promote these skills with their children, Dodge says, as should education policymakers.To Neil Bernstein, a psychologist in Washington, D. C. , who specializes in child and adolescent behavior disorders, the researchers' findings seem to match what he's seen among the general public in working with children for more than 30 years. And while he says he agrees with the importance of teaching self﹣control and social skills, he would add empathy to the list, too."Empathy is what makes us aware of the feelings of others, and when you're empathic, you're much less likely to hurt someone else's feelings, "says Bernstein, who serves on the advisory board for the Partnership for Drug﹣Free Kids. "Being in tune with how someone else feels might also make adolescents avoid bullying and other behaviors of concern, "Bernstein says.While Bernstein thinks the study's findings are meaningful and could potentially serve as a model for schools, he says that collectively getting a school system, teachers, parents and students all motivated enough to take part in an intervention like Fast Track is challenging.(1) Fast Track is aimed to.A. improve children's academic skillsB. help the children with behavior disordersC. identify the problematic childrenD. classify children into different groups(2) Neil Bernstein thinks that.A. empathic children are more likely to have higher emotional intelligenceB. the findings of the studies disagree with what he has found in his workC. empathy is equally essential in educating and socializing childrenD. self﹣control and social skills are not as important as empathy(3) What can be learned from the passageA. It's hard to involve everyone concerned in applying the findings.B. Soft skills were not part of the education system in the past.C. The findings are meaningless unless guided by Fast Track.D. Adolescence is the most critical stage in a person's life.(4) What does the passage mainly tell us？A. Academic skills are paid too much attention at schools.B. Academic skills have no influence on children's behaviors.C. Soft skills are much harder to develop than academic skills.D. Soft skills play a significant role in preventing future crimes.五、信息匹配（共4小题，每题2分，满分8分）7、【来源】 2018年上海崇明县高三一模第67~70题8分The Best Language for MathWhat's the best language for learning math？Hint：You're not reading it.Chinese, Japanese and Korean use simpler number words and express math concepts more clearly than English. The language gap is drawing growing attention as confusing English number words have been linked in several studies to weaker counting and arithmetic skill in children in English-speaking countries.1Among the researchers are Karen Fuson, a professor in the School of Education at Northwestern University, and Li Yeping, an expert on Chinese math education at TexasA&M University.Chinese has just nine number words, while English has more than two dozen. The trouble starts at "11". English has a unique word for the number, while Chinese （as well as Japanese and Korean, among other languages） have words that can be translated as "ten-one" — spoken with the "ten" first.2English number words over 10 don't as clearly label place values. Number words for the teens reverse the order of the ones and "teens", making it easy for children to confuse, say, 17 with 71. As a result, children working with English number words have a harder time doing multi-digit addition and subtraction （减法）.3It also feels more natural for Chinese speakers than for English speakers to use the "make-a-ten" addition and subtractionstrategy. When adding two numbers, students break down the numbers into parts and regroup them into tens and ones. For instance, 9 plus 5 becomes 9 plus 1 plus 4.4Many teachers in America have increased instruction in the make-a-ten method and called for first-graders to use it to add and subtract.Now, you should feel lucky that you are learning math in China. Thanks to your mother tongue, all math problems just come less confusing and difficult to you!A. So it's not easy for English speakers to label place values clearly.B. The additional mental steps needed to solve problems cause more errors.C. Differences between Chinese and English, in particular, have been studied for decades.D. This method is a powerful tool for solving more advanced multi-digit addition and subtraction problems.E. Different languages indicate different ways of thinking, causing people to solve math problems differently.F. That makes it easier for children to understand the place value as well as making it clear that the number system is based on units of 10.六、阅读简答（满分10分）8、【来源】 2018年上海崇明县高三一模第71题10分Directions：Read the following passage. Summarize the main idea and the main point（s） of the passage in no more than 60 words. Use your own words as far as possible.From Burn Survivor to Global InspirationLast October, the Kona Ironman World Championship witnessed an unbelievable finish. Turia Pitt, an Australian woman who suffered severe burns when caught in a bush fire during a marathon six years ago, successfully challenged herself.Pitt spent 864 days in a hospital and went through more than 200 operations. Doctors said she would never run again, but she proved them wrong.Crossing the line in the Hawaiian darkness, Pitt showed incredible emotion as the race commentator （现场解说员） announced："Turia Pitt, you are an ironman!" On social media, people around the world applauded her determination.Apart from continuing to be a star athlete, Pitt is also a motivational speaker now. She is sharing her journey of recovery with others to help raise awareness about the importance of organ donation, which she believes saved her life.Pitt was 24 years old when she and five others encountered the fire. Doctors had to remove the burnt skin and replace it with donated skin that could fight infection. None could be found in Australia and doctors were forced to search abroad. They finally found skin that could be used in the United States."I'm not being dramatic, but it was the skin that saved my life.", said Pitt. "I decided to live my life to the best of my abilities because I never wanted those donors, wherever they are, to think I was ungrateful for their gift. "So Pitt set herself a big goal: the Kona Ironman World Championship. In order to compete, she had to first learn how to stand, walk and even talk all over again. And because of her burns, she also has trouble sweating and regulating her body temperature.Despite these disadvantages, Pitt completed the race in just 14 hours. She said this achievement would not be possible without the donated skin, highlighting the importance of organ donation.七、翻译句子（共4小题，1、2题每题3分，3题4分，4题5分，满分15分）9、【来源】 2018年上海崇明县高三一模第72~75题15分(3分,3分,4分,5分)Directions： Translate the following sentences into English, using the words given in the brackets.(1) 你能感受到大数据给现代生活带来的冲击吗？（impact）(2) 我们在向西方学习的时候不能丢弃自己独特的文化特征. （abandon）(3) 上个月竣工的游乐园每天向公众开放, 逢星期一休息. （except）(4) 如今, 越来越多的人喜欢在网上购物, 这就促进了快递业的蓬勃发展.（which）八、书面表达（满分25分）10、【来源】 2018年上海崇明县高三一模第76题25分Write an English composition in 120-150 words according to the instructions given below in Chinese.明启中学计划在寒假的2018年2月5日至2018年2月18日（2018年2月16日为中国春节）期间组织一批学生到美国的结对学校Jenison Public School进行为期两周的交流学习, 但具体的交流内容还在研讨之中.现学校要求想要参加的学生自行向负责该项目的王老师写申请书, 并就交流的内容提出建议, 然后再由学校商讨确定交流学生的名单.假设你是该校学生李敏, 想要参加该项目, 给王老师写申请书.你的申请书需包括：•想要参加该项目的愿望；•想要参加该项目的理由；•就交流内容提出具体建议.注：文中不得提及你的真实姓名或学校.1 、【答案】 It;in which或during which;whether或if;as或when或while;looking;could;on;has drawn;that;to find;2 、【答案】 E;C;D;B;J;G;A;K;F;H;3 、【答案】 D;C;A;D;A;B;B;D;C;A;B;D;C;B;C;4 、【答案】 (1) D;(2) C;(3) A;(4) C;5 、【答案】 (1) B;(2) D;(3) B;6 、【答案】 (1) B;(2) C;(3) A;(4) D;7 、【答案】 C;F;B;D;8 、【答案】Turia Pittmet with a fire during a marathon and got severely burnt 6 years ago.
