高考模拟检测12本试卷分第Ⅰ卷(阅读题)和第Ⅱ卷(表达题)两部分。

共150分，考试时间150分钟。

第Ⅰ卷(阅读题，共70分)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。

孔子所处的春秋时代，正值“富者田连阡陌，贫者亡立锥之地”。

基于对这一现象的担忧，为了维护社会安定，巩固封建统治，孔子提出了如下思想：“丘也闻有国有家者，不患寡而患不均，不患贫而患不安。

盖均无贫，和无寡，安无倾。

”(《论语·季氏》)一些人把“寡”解为土地财产少当是误读，所谓“寡”类似于老子“小国寡民”中的“寡民”。

孔子的“贫”是指土地和财产少。

孔子的“均”应有两解：一是“平均”，如《荀子·君道》“以礼分施，均遍而不偏”；二是“公平”，相当于《管子·形势》所言“天公平而无私，故美恶莫不覆；地公平而无私，故小大莫不载”。

这段话经常被当作儒家宣传平均主义的经典表达加以批判。

有的学者指出，社会财富分配的公正合理，确实是社会稳定的前提之一，但孔子“患不均”之正确，并不能证明“不患贫”之合理；“均无贫”不合事实，“不均才贫”更不合逻辑；“均”是分配形式，“贫”是财富多少，财富分配之均与不均，与财富之多少没有关系。

“不患贫”是危险的，因为“贫”正是“不安”的首要原因；物贫则人争，争则不安；人所争者，正是这不足之物。

“均无贫”彻底的没逻辑，其极端形式是人人都是零，也就不是贫；而人人都是零，均是绝对均了，但贫还是贫。

这番言论虽不乏深刻，但存在诸多误解。

不能脱离特定的语境加以解释。

要知道，孔子这段话是针对季康子掌权者之流通过对外战争攻伐等不义手段掠夺土地和人口而讲的，不是泛泛而论。

他分别把“均”“和”“安”和“贫”“寡”“倾”当作两种价值，“不患寡而患不均，不患贫而患不安”表面上看是只追求平均、安定而排斥土地和人口的增加，其实不然，他不过是强调通过采用“均”“和”“安”的手段和途径达到解决“贫”“寡”“倾”的问题。

The leaves, the conkers and the rain are falling; our picnic days are over. Never fear, there's still plenty of family fun to be had in London's top five museums for kids.London's Night Owls SleepoverExplore the Museum of London by torchlight at these special after-hours events for ages seven to eleven.Pillows and PaintbrushesKids aged seven to thirteen can embark on a very arty overnight at the Dulwich Picture Gallery on its first ever sleepover.Michael Rosen's Bear Hunt, Chocolate Cake and Bad ThingsMuch-loved children's author Michael Rosen is behind this interactive family exhibition which reveals the inspiration behind his writing. Younger children will explore a Bear Hunt trail, while older kids can go on a mission to find facts which they can use for inspiration to write their very own poem to take home.Free Range Urban KidsChildren aged three to five can be dropped off for a forest adventure that might include den building, mini-beast-hunting, foraging, wildlife spotting, singing and free play (tots aged two to three can attend with a parent) .The Comedy of Errors"The Comedy of Errors" returns to the National Theatre, this time in a new production forages eight to twelve by Ben Power. It should be a short, sweet and fun version of the tale of two sets of identical twins that get separated and then reunited.1．Kim has two children, aged 4 and 11 respectively, so he will probably chooseA.

On my way to school I wondered what sort of questions the other boys would ask me and rehearsed all the answers: "I am nine years old. I was born here but I haven't lived here since I was two. I was living in Farley. It's about thirty miles away. I came back to London two months ago." I also wondered if it was the custom for boys to fight strangers like me, but I was tall for my age. I hoped they would decide not to risk it.No one took any notice of me before school. I stood in the center of the playground, expecting someone to say "hello", but no one spoke to me. When a teacher called my name and told me where my classroom was, one or two boys looked at me but that was all the curiosity my arrival aroused.My teacher was called Mr. Jones. There were 42 boys in the class, so I didn't stand out there, either, until the first lesson of the afternoon. Mr. Jones was very fond of Charles Dicker and he had decided to read aloud to us from David Copperfield, but first he asked several boys . they knew Dickens' birthplace, but no one guessed right. A boy called Brian, the biggest in the class, said: "Timbuktu", and Mr. Jones went red in the face. Then he asked me. I said "Portsmouth", and everyone stared at me because Mr. Jones said I was right. This didn't make me very popular, of course. "He thinks he's clever," I heard Brian sayAfter that, we went out to the playground to play football. I was in Brian's team, and he obviously bad Dickens in mind because he told me to go in goal. No one ever wanted to be the goalkeeper. "He's big enough and useless enough," Brian said when someone asked him why he had chosen me.I suppose Mr. Jones remembered Dickens, too, because when the game was nearly over, Brian pushed one of the players on the other team, and he gave them a penalty. As the boy kicked the ball hard along the ground to my night, I threw my self down instinctively and saved itAll my team crowded round me. My bare knees were grazed and bleeding. Brian took out a handkerchief and offered it to me."Do you want to join my gang (team) ?" he said.At the end of the day, I was no longer a stranger.4. Which of the following statements is true about the writer?A．He was born in Farley and moved to London two months ago.B．He was taller than most of his classmates because he was older.C．He knew what sorts of questions his classmates would ask and he had prepared answers.D．He looked forward to his new school life but were afraid that the boys might not be friendly 5．We can learn from the passage that .A．boys were usually unfriendly to new studentsB．the writer was not greeted as he had expectedC．Brian envied the writer because the teacher thought he was cleverD．the writer was chosen as the goalkeeper because he was useless and big6. The underlined part "I didn't stand out" in paragraph 3 means that the writer was notA．noticeable B．welcomeC．important D．outstanding7．The writer was offered a handkerchief becauseA．he threw him self down and saved the goalB．his bare knees were bleedingC．he was beginning to be acceptedD．he joined Brian's gangCPublicity offers several benefits. There are not costs for message time or space. An ad in prime-time television may cost $250,000 to $5,000,000 or more per minute, whereas a five-minute report on a network newscast would not cost anything. Publicity reaches a mass audience within a short time and new products or company policies are widely known Credibility about messages is high, because they are reported in independent media. A newspaper review of a movie has more credibility than an ad in the same paper, because the reader associates independence with objectivity (客观现实). Similarly, people are more likely to pay attention to news reports than to ads. For example, Women's Wear Daily has both fashion reports and advertisements. Readers spend time reading the stories, but they skim through the ads. Furthermore, there may be 10 commercials during a half-hour television program or hundreds of ads in a magazine. Feature stories are much fewer in number and stand out clearly.Publicity has some significant limitations. A firm has little control over messages, their timing, their placement, or their coverage by a given medium. It may issue detailed news releases but find only portions mentioned by the media, and media have the ability to be much more critical than a firm would like.For example, in 1982, Procter & Gamble faced a massive publicity problem over the meaning of its 123-year-old company logo. To fight this negative publicity, the firm had a spokespersonappear on Good Morning America to disprove the rumor (谣言). The false rumors were temporarily put to rest. However, in 1985, publicity became so trouble-making that Procter & Gamble decided to remove the logo from its products.A firm may want publicity during certain periods, such as when a new product is introduced or new store opened, but the media may not cover the introduction or opening until after the time it would aid the firm. Similarly, media determine the placement of a story; it may follow a report on crime or political scandal. Finally, the media decide whether to cover a story at all and the amount of coverage to be devoted to it.8．All of the following advantages of publicity are mentioned EXCEPTA. time savingB. money savingC．profitability D．credibility9．What does "it 'in paragraph 3 refer to?A．A giver medium B．A firm C．Publicity D．Coverage 10．Which of the following statements is true?A．A five-minute report via the media would not cost people any moneyB．Procter & Gamble fighted against another company on company logo.C．Ads appear less believable merely because there are too many of them.D．Timing of publicity can influence the efficiency of promoting products.11．What's the author's attitude towards publicity?A．Objective. B．Doubtful. C．Passive. D．Supportive.DSunny countries are often poor. A shame, then, that solar power is still quite expensive. Eight19, a British company by Cambridge University, has, however, invented a novel way to get round this. In return for a deposit of around $10 it is supplying poor Kenyan families with a solar cell able to generate 2.5 watts of electricity, a battery that can deliver a three amp (安培) current to store this electricity, and a lamp whose bulb is a light-emitting diode(二极管). The firm thinks that this system, once the battery is fully charged, is enough to light two small rooms and to power a mobile-phone charger for seven hours. Then, next day, it can be put outside and charged back up again.The trick is that, to be able to use the electricity, the system's keeper must buy a scratch car d—for as little as a dollar－on which is printed a reference number. The keeper sends this reference, plus the serial number of the household solar unit, by SMS to Eight19. The company's server will respond automatically with an access code to the unit.Users may consider that they are paying an hourly rate for their electricity. In fact, they are paying off the cost of the unit. After buying around $80 worth of scratch cards - which Eight19 expects would take the average family around 18 months - the user will own it. He will then have the option of continuing to use it for nothing, or of trading it in for a bigger one, perhaps driven by a 10-watt solar cell.In that case, be would go then through the same process again, paying off the additional cost of the upgraded kit at a slightly higher rate. Users would therefore increase their electricity supplysteadily and affordably.According to Eight19's figures, this looks like a good deal for customers. The firm believes the average energy-starved Kenyan spends around $10 a month on oil - enough to fuel a couple of smoky lamps - plus $2 on charging his mobile phone in the market-place. Regular users of one of Eight19's basic solar units will spend around half that, before owning it completely. Meanwhile, as the cost of solar technology falls, it should get even cheaper.12．Where can the users find the reference number needed if they want to use electricity?A. On the battery.B. On the scratch card.C. On the solar unit.D. In the automatic message.13．How much would users pay for the cell and scratch cards before they own a 2.5-watt solar cell?A. Around $10.B. Around $80.C. Around $90.D. Around $180.14．Which of the following statements is true according to the passage?A. Users pay for the eletricity by the hour.B. Users can get a bigger unit free of charge.C. The reference number on the scratch card is the access code to the solar unit.D. The price of the solar units may decrease in the future according to Eight19.15. What might be the most suitable title for the passage?A. Solar Energy: Starting from Scratch.B. Eight19: a creative British Company.C. Kenyan Families: Using Solar Energy for Free.D. Poor Countries: Beginning to Use Solar Energy.第二节根据短文内容，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。

礼仪文化与社会主义核心价值观蒋璟萍中国礼仪文化博大精深，蕴含着丰富的思想内涵，代表着社会的价值观念。

从基本框架看，礼仪文化蕴含着善良、和谐、秩序的价值观念。

第一，追求善良的价值观念。

从个人的视角看，礼仪是一种“向善”的价值追求。

孟子认为，“辞让之心，礼之端也”，它同“恻隐之心”“羞恶之心”“是非之心”皆为“善端”，由此形成仁、义、礼、智“四德”，进而达到至善。

礼仪表现出善良的人性，雍容大度的仪态，彬彬有礼的行为，庄重诚敬的仪式，表明与人为善的态度，善良宽容的心灵。

第二，追求和谐的价值观念。

从社会的视角看，礼仪是一种“为和”的价值追求。

儒家强调，“礼之用，和为贵”。

礼仪是以建立和谐关系为目标的行为规范，礼让包含对自我的克制，对他人的理解，体现以礼待人的尊重，乐群贵和的美德。

第三，追求秩序的价值观念。

从国家的视角看，礼仪是一种“有序”的价值追求。

“礼，经国家，定社稷，序民人，利后嗣者也”，“国无礼则不宁”。

孔子以礼为基础，提出一套完整的规范体系，进而建立有条不紊的社会秩序。

礼仪是经世治国的道德秩序，人们遵循礼仪规范，各就其位，各司其职，国家就会秩序井然。

中国礼仪文化根植于传统社会，不可避免地带有封建思想的印迹。

然而，遵循“取其精华，去其糟粕”的原则，挖掘其中的合理内核，就可以提炼一些超越时空的价值观念。

将礼仪文化中蕴含的向善、为和、有序的价值观念，放进现代文化的框架下进行科学的阐释，就可以融入社会主义核心价值观，使之与友善、和谐、文明、法制等现代价值观念相联系，成为涵养核心价值观的重要源泉。

中国礼仪文化有着深刻的价值观内涵，传统礼仪文化教育也有着其独特的优势。

为此，我们应该充分发挥礼仪文化教育的优势，将核心价值观教育和礼仪文化教育有机地结合起来，以礼仪文化教育促进社会主义核心价值观教育的落实。

民谣谚语，是人们世世代代的生活经验的高度总结与卓越智慧的长期积淀，有着极为丰富、深厚的内涵，是极富特色的传统民间文化的形式之一。

两宋时期的民间谣谚中，有大量的倡导廉洁、颂扬廉政的内容。

宋人认为：为官之要，曰廉曰勤。

岳飞更是直率地指出：文臣不爱钱，武臣不惜死，天下太平矣。

至于名相范仲淹，则其境界更高。

他提出：先天下之忧而忧，后天下之乐而乐；清心做官，莫营私利。

这些至理名言，后多成为人们的口头禅，转化为歌谣民谚。

另外，当时还有劝廉、守廉的民谣。

例如，世常羞贫贱，贫贱非我羞；人人为官莫敛财；住世一日，则做一日好人，居官一日，则做一日好事；否则尔俸尔禄，民膏民脂，下民易虐，上天难欺。

这些或诗或歌的民谣，代表了广大民众希望官场廉洁、官员廉正、不奢华、莫敛财的良好愿望。

据传，当时民歌谣谚中还广为流传着宋真宗写的《劝学诗》：“富家不用买良田，书中自有千钟粟。

安房不用架高梁，书中自有黄金屋。

娶妻莫恨无良媒，书中自有颜如玉。

出门莫恨无随人,书中车马多如簇。

男儿欲遂平生志，六经勤向窗前读。

”诗歌既有劝人勤学苦读的用意,也将读书、做官、发财之间的关系写得清楚明白。

但不论怎么说，学而优则仕，总比不学无术、只顾投机钻营和贪赃枉法要好。

因此，时人又唱道：谁不爱，黄金屋；谁不羡，千钟粟。

但他们也深知“儿孙自有儿孙福,何必为官去贪污”;且“富贵有余乐,贫贱不堪忧”。

两宋时期，大量的民谣谚语表达了人们对贪官污吏的愤恨，尤其是对北宋末年童贯、蔡京、朱勔等人的切齿之恨。

如贪官朱勔受宠，仅家奴即有百余人封官赐爵。

其中受金带者至有数十人。

当时民谣说：金腰带，银腰带，赵家世界，朱家坏！具有讽刺意味的是，这些以贪污勒索的钱财而换取的腰带到手后，又被高价转卖，从而大获其利。
