From the first day of class, Sara impressed me with her ability to clearly explaindifficult1and texts, her sensitivity to the slight differences within literature, and her passion for reading, writing, and creative expression - both in and out of the classroom. Sara is atalented literary critic and poet, and she has my highest2as a student and writer.Sara is talented at considering the elegances within literature andthe3behind authors' works. She produced an extraordinary year-long thesis paper on creative identity development, in which she compared works from three different time periods and synthesized cultural and historical4to inform her analysis. When called upon to give her thesis defense in front of her peers, Sara spoke clearlyand5about her conclusions and responded to questions in a thoughtful way. Outside of the classroom, Sara is devoted to her literary pursuits, especially to poetry. She publishes her poetry in our school's literary magazine, as well as in online magazines. She is an insightful, sensitive, and deeply self-aware individual driven to6art, writing, and a deeper understanding of the human condition.Throughout the year Sara was an active participant in our discussions, and she always supported her peers. Her caring nature and personality allow her to work well with others in a team setting, as she always respects others' opinions even when they differ from her own. When we held a class debate about gun laws, Sara chose to speak for the side opposite her own views. She explained her choiceas7by a desire to put herself in other people's shoes, view the issues from a new perspective, and gain a clearer sense of the issue from all angles. Throughout the year,Sara8this openness to the opinions, feelings, and perspectives of others, along with sharp powers of observation, all9that make her outstanding as a student of literature and burgeoning writer.I am certain that Sara is going to continue to do great and creative things in her future. I highly recommend her for admission to your undergraduate program. She is talented, caring, dedicated, and focused in her pursuits.

The UnitedStates4entered into the agreement in September, and more countries are expected to come aboard in the coming weeks and months.United Nations Secretary General Ban-Ki Moon celebrated the event, talking with nongovernmental groups at U.N. headquarters in New York to hear their concerns and5for the future."This is an emotional moment for me.

The ones marchingacross my kitchen counter looked so confident; I just figured they had a plan, knew where they were going and what needed to be done. How else could ants organize highways, build elaborate nests, launch impressive attacks, and do all the other things ants do?Turns out I was wrong. Ants aren't clever little engineers, architects, or soldiers after all—at least not as individuals. When it comes to deciding what to do next, most ants don't have a clue. "If you watch an ant try to accomplish something, you'll be impressed by how awkward it is, " says Deborah M. Gordon, a biologist at Stanford University."Ants aren't smart, " Gordon says. "Ant colonies are." A colony can solve problems unthinkable for individual ants, such as finding the shortest path to the best food source, assigning workers to different tasks, or defending a territory from neighbors. As individuals, ants might be tiny dummies, but as colonies they respond quickly and effectively to their environment. They do it with something called collective intelligence.Where this intelligence comes from raises an essential question in nature: How do the simple actions of individual ants add up to the complex behavior of a group? How do hundreds of honey-bees make a critical decision about their hive（蜂巢）if many of them disagree? The collective abilities of such animals—one of which grasps the big picture, but each of which contributes to the group's success—seem miraculous even to the biologists who know them best. Yet during the past few decades, researchers have come up with fascinating insights.(1) The author's former false impression about ants is that he thought them tobe.A. smartB. awkwardC. elaborateD. creative(2) Which of the following is TRUE according to the passage?A. Ants will function as a single body once a decision is made by the commander.B. Ants are the only species which developed collective intelligence.C. The ant queen plays a role in managing ant workers besides laying eggs.D. An individual ant can't comprehend the whole process of a big movement.(3) The paragraph following the passage will most probably deal with.A. where we can observe such fantastic behavior of antsB. which is the leading ant in charge of the actionC. how the collective intelligence worksD. what inspiration can be drawn from the collective abilities5、【来源】 2017年上海徐汇区高三二模（B篇）第59~62题8分The idea of using radio or wireless to broadcast to audiences was formed in 1916by a president of the American Marconi Company, David Sarnoff. His superiors were doubtful about his idea to "make radio a household cause, so that by purchase of a 'radio music box', the audience could enjoy lectures, music performance, etc."Four years later the American engineer Frank Conrad, an employee at W E Corp, attracted considerable attention when a local newspaper reported on the growing audience listening on crystal radio sets to his evening and weekend amateur broadcasts. A local music store had provided records to play on the Victoria, and Conrad and his family served as disc jockeys（唱片音乐播音员）. Westinghouse vice president Harry Davis asked Conrad to build a more powerful transmitter（发射台）in time to announce the outcome of the next US presidential election. Conrad completed his assignment, and on November 2, 1920, station KDKA in Pittsburgh, Pennsylvania, broadcast the announcement that Warren G. Harding had been elected president. About 1000 people heard this first news broadcast.Radio communicated news much faster than did newspapers, and because crystal sets were easy to build and inexpensive, radio expanded rapidly in the following years. To stimulate the sale of radio sets, equipment manufactures provided transmitting facilities. Singers, comedians, and entire orchestrasvolunteered their services for publicity. The eventual financial basis of the new industry, however, was still unclear. One group in New York City tried to seek contributions from listeners while others urged that private foundations support radio stations as a public service. In August 1922 the first commercial radio advertisement was broadcast on WEAF （now WNBC） in New York City. In 1926, when about 5 million homes had radios, the Radio Corporation of America （RCA）, in cooperation with the American Telephone & Telegraph Company, established the first commercial radio network.

For ten months the 28 men aboard Shackleton's ship waited and prayed for ice to break. When it finally did, the Endurance sank, leaving the crew homeless and adrift on a sea of ice in one of the world's most dangerous environments.In January 2000 a luxury ocean liner found itself similarly trapped in the cold waters off Antarctica. Argentine authorities sent off an icebreaker straight away from the nearest naval base, and in 24 hours, all 176 passengers and crew were free. The tour company's spokesperson TAL#NBSP spun the potential disaster as a value-added reward in extreme travel. "The people on board are looking at this as sort of a great adventure, " she said.Ever since Jon Krakauer's book Into Thin Air made Everest a household name, the subculture of adventure has blown up like a Himalayan avalanche（雪崩）into public consciousness. Magazines promise "extreme" content, television, offers adventure programs, and the growing collective fascination with adventure has produced a flow of published accounts about the world's greatest adventurous journey. Nowadays more and more people are interested in adventure and this mass appeal makes good business sense. Today the only thing blocking a would-be adventurer's passage to Antarctica is the cost—which typically runs well over $10, 000.Despite very different implications, adventure was just as popular in Shackleton's time. He has little trouble filling the Endurance—5, 000 men are said to have responded to his recruitment（招募）notice: "Men wanted for risky journey. Small wages. Bitter cold. Long months of complete darkness. Constant danger. Safe return doubtful."After five months drifting on ice, the crew were forced to take to their lifeboats to Elephant Island. Reaching the wasteland, Shackleton went on with one lifeboat and five of his best men 1, 300 kilometers across the bone-chilly Scotia Sea to South Georgia Island. Shivering with cold, dressed in rags, Shackleton marched into a whaling station and set about organizing a rescue expedition to Elephant Island. Almost two years after becoming shipwrecked on ice, Shackleton picked up his crew. "Not a life lost, and we have been through hell, " he remarked earnestly.(1) We can learn from the first sentence of this passage that.A. the age of adventure began with the ship Endurance trapped in iceB. Shackleton's adventure marked the highest point of pure explorationC. the age of adventure ended with the ship Endurance trapped in iceD. Shackleton's adventure predicted that the golden age of exploration was approaching(2) The word "spun" in the second paragraph can be replaced by "".A. summed upB. judgedC. boasted aboutD. referred to(3) Since Jon Krakauer's book was published.A. the media have got interested in the topic of adventureB. the costs of extreme travel have gone upC. Everest has got its name known to EuropeD. people have got fascinated by Himalayan avalanches(4) The adventure in Shackleton's time has different implications from today's inthat.A. Shackleton's adventure lasted longer then any other adventure nowadaysB. no one was missing during Shackleton's adventureC. Shackleton's adventure was entirely for the sake of adventureD. Shackleton enrolled volunteers more easily四、6选47、【来源】 2017年上海徐汇区高三二模第67~70题8分2018~2019学年上海崇明县崇明中学高二上学期期中第40~43题2017~2018学年10月上海虹口区上海市复兴高级中学高一上学期月考第62~65题8分(每题2分)My wife and I recently welcomed a child into the world. His only interest right now is keeping us awake 24/7. But one day, he'll need to learn something about finance. When he does, here are some suggestions.1. You might think you want an expensive car, a fancy watch, and a huge house. But youdon't.1You think having expensive stuff will bring it. It almost never does—especially from the people you want to respect and admire you.2. The road to financial regret is paved with debt. Some debt, such as a mortgage, is OK. But most spending that results in debt is the equivalent of a drug: a quick hit of pleasure that wears off, only to drag you down for years to come, limiting your options and keeping you weighed down by the baggage of your past.3. I hope you're poor at some point. Not struggling, and not unhappy, of course. But there's no way to learn the value of money without feeling the power of its scarcity. It teaches you the difference between necessary and desirable.2These are essential survival skills.4. If you're like most people, you'll spend most of your adult life thinking, "Once I've saved/earned X dollars, everything will be great." Then you'll hit X dollars, move the goalposts, and resume chasing your tail. It's a miserable cycle. Your goals should be about more than money.5. Don't stay in a job you hate because you made a career choice at 18. Almost no one knows what he or she wants to do at that age. Many people don't know what they want until they're twice that age. （These are the signs you're in the wrong career.）6. The best thing money buys is to control over your time.3One day you'll realize that this freedom is one of the things that makes you truly happy.7. Change your mind when you need to. I've noticed a tendency for people to think they've mastered investing when they're young. They start investing at age 18 and think they have it all figured out by age 19. They never do.8. Some people are born into families that encourage education; others are from families that are against it. Some are born into flourishing economies; others, into war and poverty. I want you to be successful, and I want you to earn it. But realize that not all success is due to hard work and not all poverty is due to laziness. Keep this in mind when judging people, including yourself.9. Your savings rate has a little to do with how much you earn and a lot to do with how much you spend. I know a dentist who lives paycheck to paycheck, always on the edge of ruin. I know another person who never earned more than $50, 000 and saved a fortune. The difference is entirely due to their spending.410. Don't listen to me if you disagree with what I've written. The world you grow up in will have different values and opportunities than the one I did. More important, you'll learn best when you disagree with someone and then are forced to learn it yourself.（On the other hand, always listen to your mother.）A. It'll make you learn to enjoy what you have, fix what's broken, and shop for a bargain.B. Spending more is likely to stimulate your motivation for more earning.C. It gives you options and frees you from relying on someone else's priorities.D. Living with less is the most efficient way to control your financial future.E. Actually, your parents have already given you too much.F. What you want is respect and admiration from other people.五、篇章总结8、【来源】 2017年上海徐汇区高三二模第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.Meet The Member Who Quit SugarWhen I was 15, I weighed 100 kg.I was a size 20+ and hated the way I looked. I was a serial big eater and quite depressed. I would sit in front of the fridge, eat something, move to the cupboard, eat a packet of chips, and move back to the fridge.It was a heartbreaking cycle of hate and food. I didn't feel confident, pretty, or worthwhile.Shopping made me cry, I avoided mirrors, and my social life came to an end. I actually lost friends because they told me I was antisocial. It became so bad that I wanted to abuse myself; my skin and my mind became my enemy.But then, I turned my life around. I quit sugar.It started with my mum. She staged an intervention（干预）that made me cry. I wanted to change - I needed to change - and she could see how unhappy I was.She put me onto a diet that mostly aimed to schedule meals, and - to my shock horror - cut out all processed sugar. It was so hard at first. I remember the shame of sneaking chocolate and candies when the three o'clock hunger hits.But the weeks kept coming and it just got easier. I stopped eating sugar, and I stopped loving it; simple as that.I substituted chips and biscuits for fruit and nuts, and had cup-of-soups after school when I was hit by the desire. I also had more energy, having a 20-minute walk with my dog into my everyday routine; I began to love that personal time.Cutting out sugar gave me so much more control over my body, and my outlook on life improved. So many people are intimidated by the words "quit sugar". It's not true. Fruit, honey, et cetera are natural sugars, and believe me, they fuel you better than chocolate bars ever could.Now I'm 17, turning 18, and I weigh 70 kg. I still struggle with my weight, but this is where I sit naturally, and I am very proud of myself. I never thought I would be confident enough to wear dresses or skirts, and take leadership roles to put myself out there and develop my social skills.I could never have done it without the support of my friends and family, and I urge everyone who wants to do right by themselves and change their diet - quitting sugar or otherwise - to share their decision with people. Develop a support network, online or offline, which can offer you advice or pick you up when you're down. And I can assure you, from my own personal experience, your body will thank you, and you will thank yourself too.六、翻译句子9、【来源】 2017年上海徐汇区高三二模第72~75题15分Directions:Translate the following sentences into English, using the words given in the brackets.(1) 铃声一响，孩子们就冲了出来。

30二阅读 70分3132（一）阅读下列文章，完成第3—8题。
（16分）33①尽管网络文学已经发展了十几年，但什么是网络文学仍没有一个统一的3435定义。
不过，如果从媒介革命的视野出发，在不久的将来应该不再存在网络文36学的概念，相反会出现“纸质文学”的概念。
除了作为“博物馆艺术”传承的纸质文学外，网络将成为一切主流、非主流文学艺术的平台。
372②目前的网络文学以类型小说为主，但也不是铁板一块。
随着 2012 年互3839联网进入移动时代，针对移动受众阅读时间碎片化的特点，一些主打“小而美”注的 APP 终端应运而生，如韩寒主编的《ONE·一个》，中文在线推出的“汤圆4041创作”，专门发表短篇小说的“果仁小说”，此外微博、微信公共账号也是相42当活跃的个人作品发表平台。
与此同时，传统文学期刊也开始进行“网络移民”，43如由《人民文学》杂志推出的手机阅读平台“醒客”也于 2014 年 7 月上线。
44不过，传统文学要成功地实现“网络移民．．．．”不可能是原封不动的“穿越”，而45是要经过脱胎换骨的“重生”。
“内容一经媒介必然发生变化”，这是麦克卢46汉那句“媒介即信息”断言的重要含义。
所以，与其我们现在努力参照纸质文学的概念定义网络文学，不如直接去研究“网络类型小说”“直播贴”“微小4748说”这些自然生长起来的网络文学形态，在此基础上进行总结。
49③媒介革命已经不以人的意志为转移地发生了，网络时代主流文学的建构必然是以网络为平台的。
在这个汇集各种年龄、各种文化结构和文学趣味的“全5051平台”上，占据主流的应该还是类型小说，这是大众阅读需要决定的，也是文52化工业的性质决定的。
在理想的状态下，类型小说应该是分层的。
其实网文作者现在就有“小白”和“文青”之分，“小白文”追求“爽”，“文青文”在5354追求“爽”的同时，还强调文笔和情怀。
“文青”的粉丝团在人数上通常比不55上“小白”，但文化层次和忠诚度都更高。
某种意义上说，有些“另类”的“文56青”代表着类型文中的精英倾向——这里不是光有几个“大神”，还有他们大57量的铁杆粉丝。
由于网络文学即时互动的特点，每一部小说都凝聚了无数“集58体的智慧”，作者更像是“总执笔人”。
如果没有相当数量的“铁粉”出钱出力、鼎力支持，在“小白当道”的总体阅读环境下，“文青大神”是活不下来5960的。
从这个意义上说，有几流读者才有几流作者。
361④在大众的类型小说之外，还应该有各种小众的圈子，如“耽美圈”“同62人圈”，以及上面提到的各种“小而美”等文学形态。
这些“非主流”的小众63圈子或有亚文化色彩，或有纯文学趋向，在文化观念或文学观念上进行探索，64它们探索的成果可以推动更大众、更主流的文学的不断发展。
对小众成果的吸65收主要是由大众文学中的精英圈完成的，他们不但要吸收各种小众的文学成果，66还要与思想界和文化界保持连通。
大师级的大众文学作品不是只满足受众的阅67读欲望，还要缓解他们的焦虑，安抚他们的灵魂，网络文学这样的“集体创作”68更是如此。
如果这些作品能够与主流价值观对接，甚或参与主流价值观的建构，就自然是实至名归的主流文学。
6970⑤在主流文学建构的过程中，精英批评的力量是十分重要的。
现在这部分71工作主要是由“精英粉丝”自发完成的。
学院派研究者如果要有效介入，必须72重新调整定位。
这不仅意味着研究方法的全面更新，同时也意味着研究态度发73生根本性的变化——不能再以中立的、客观的、专业的超然态度自居，而是要74以“学者粉丝”的身份进行“介入式研究”。
研究成果发表的空间也不应只局限于学术期刊，而是应该进入网络生产场域。
比如，对于现在网络文学的研究，7576如果学院派网络文学批评能够对具有精英倾向的作品进行深入解读，在点击率77和网站排行榜之外，再造一个真正有影响力的精英榜，影响粉丝们的“辨别力”与“区隔”，那么就能真正“介入性”地影响网络文学的发展，并参与主流文7879学的打造了。
80【注】小而美：在一个大工业生产均质化的时代，提倡“选取一个点，做到极致”的理念。
818243.第②段加点词语“‘网络移民’”在文中是指_________________________8384（2分）854.对支撑第③段划线句子这一结论的理由，推断正确的一项是（）86A．因为网络方便了作者和粉丝读者即时互动。
87B．因为网络作品是粉丝读者集体创作出来的。
88C．因为粉丝读者对所“粉”作品忠诚度极高。
89D．因为读者对所“粉”作品给予了财力支持。

（15分）113114穿过一条街115陈启文116①一条腿蹲着，一条腿跪着，一个宽厚的被汗水浸湿了的背脊，连同117一个身躯，深深地俯向大地，如同某种庄严的朝拜。
这是一个人的姿态，也是118一条街的开端。
6②我说的是长青街，长安的长青街，像长青藤一样从二十多年119．．．．的岁月120里延伸过来。
第一次走到这条街上，我突然觉得脚底奇怪地发虚。
用两只脚使121劲地踏踏地，还是发虚。
这并非幻觉，我听见了水声。
一条街的历史是一条河122流，这不是比喻而是事实，就在我的脚底下，她正带着响声和气流哗哗流淌。
123③确切地说，踩在脚底下的是一条很大的水渠，灌溉着属于长安的四万多124亩农田。
把一条繁华大街直接铺在了一条水渠的上面，设计者居然想出了这样125一个绝妙的主意，让人觉得不可思议。
同样不可思议的是，不到三十年．．．．．，长安126周边的田野里异常蓬勃地生长出一大片一大片与庄稼无关的事物，生长出工厂，127楼宇，街道，公园……长安似乎一夜之间从一个小镇长城了一个现代海滨城市。
128④穿过一条街，如果你愿意把头低下来一点，你会看见他。
没有人看清过129他的脸。
我是说那个一条腿蹲着、一条腿跪着的汉子，他一天到晚就这样俯着130身，低着头，以这样一种姿势在一条街上一寸一寸地挪动。
他不是乞丐，他的131两只手从没有向任何人伸出过，而是一次又一次地抓住一样异常坚硬的东西，132比划，放下去，又拿起来，比划，再放下去。
如果你愿意把头低下来一点，你133会看见那双手。
那是一双沾满了泥浆和沙石的手，它曾握紧过犁耙，播下过种134子，连根拔起过田野里的稗草。
现在他一手握着砌刀一手拿着方砖，神情专注。
135从这条街上铺上第一块方砖开始，他就这样俯着身子，二十多年了．．．．．，时间在他这里几乎停滞了。
136137⑤花岗岩的方砖，黑质而白章。
一条街因为有了这样的花岗岩而彻底138变得像条街。
穿过这样一条街，似乎就像穿过伦敦的一条商业街，街道两旁布139满了专卖店，咖啡馆，书店，戏院……那里也有铺街人，一条腿蹲着，一条腿140跪着，一只手反复地比划着手里的方砖，比划了一阵，觉得累了，便去咖啡店7里喝咖啡，闲聊，神侃。
你不知道他们会在咖啡馆里呆多久才会出来。
然而，141142这里是中国，是长安的长青街，铺街人累了，就躺在街边的角落，躺在自己的143脏衣服上，一张报纸盖在脸上，睡着了。
南方炽热的太阳在他们梦中照着，睡上一会，又在自己的脏衣服上异常清醒地醒来，继续拿起方砖握着砌刀。
144145⑥这些看上去什么也不想的粗人，算账时脑子异常清醒。
当年他在这里铺146一块方砖是一分钱，而现在是一毛钱。
二十年一代人，现在他有了一个帮手，147在他背后，是他儿子。
他们在这里多铺一块方砖，就等于给家里的楼房添了一148块砖，加了一片瓦。
