阜宁中学高三年级暑假作业1-10
阜宁中学高三年级语文暑假作业（一）一、提取下面一段话的主要信息，写出四个关键词语。
从甲骨文到草书、行书的各种书法艺术，间接的反映了现实某些方面的属性，将具体的形式集中概括为抽象的意象，通过视觉来启发人们的想象力，调动人们的情感，使人们从意象中体味到其间所蕴含的美。
这也是一些讲书法的文章里常说的“舍貌取神”──舍弃客观事物的具体现象特征，而摄取其神髓。
————————————————二、阅读下面的文言文，完成1—4题。
阳城，字亢宗，定州北平人。
城谦恭简素，遇人长幼如一。
远近慕其行，来学者迹接于道。
闾里有争讼，不诣官而诣城决之。
有盗其树者，城过之，虑其耻，退自匿。
尝绝粮，遣奴求米，奴以米易酒，醉卧于路。
城怪其故，与弟迎之，奴未醒，乃负以归。
及觉，痛咎谢，城曰：“寒而饮，何责焉？”山东节度府闻城义者，发使遗五百缣，戒使者不令返。
城固辞，使者委而去，城置之未尝发。
会里人郑俶欲葬亲，贷于人无得，城知其然，举缣与之。
德宗召拜右谏议大夫，遣长安尉杨宁赍束帛诣其家。
初，城未起，缙绅想见风采。
既兴草茅，处谏诤官，士以为且死职，天下益惮之。
及受命，它谏官论事苛细纷纷，帝厌苦。
而城方与二弟延宾客，日夜剧饮。
客欲谏止者，城揣知其情，强饮客，客辞，即自引满，客不得已，与酬酢，或醉仆席上，城或先醉卧客怀中，不能听客语。
常以木枕布衾质钱，人重其贤，争售之。
每约二弟：“吾所俸入，而可度月食米几何，薪菜盐几钱，先具之，余送酒家，无留也。
”服用无赢副，客或称其佳可爱，辄喜，举授之。
有陈苌者，侯其得俸，常往称钱之美，月有获焉。
及裴延龄诬逐陆赞等，帝怒甚，无敢言。
城闻，曰：“吾谏官，不可令天子杀无罪大臣。
”乃约拾遗王仲舒上疏极论延龄罪；慷慨引谊，申直赞等，累日不止。
帝大怒，召宰相抵城罪。
顺宗方为皇太子，为开救，得免。
然帝意不已，欲遂相延龄。
城显语曰：“延龄为相，吾当取白麻坏之，哭于廷。
”帝不相延龄，城力也。
城出为道州刺史，州产侏儒，岁贡诸朝，城哀其生离，无所进。
人大附中2023届高三暑假自主复习检测练习语文试题及答案
人大附中2023届高三暑假自主复习检测练习语文一、本大题共5小题，共18分。
阅读下面的材料，完成1-5题。
材料一什么是经典？常念为经，常数为典。
经典就是经得起重复，常被人想起，不会忘记。
经典的书，人们一遍遍地读，一代代地读。
不但文字的经典这样，就是音乐、绘画等一切艺术品都是这样。
历史上许多不经意之说之作，无心插柳柳成阴，一不经意成了经典。
当然，经典也有呕心沥血、积久而成的。
像米开朗琪罗的壁画《末日的宣判》，一画就是八年。
不管是妙手偶成还是苦修所得，总之，它达到了那个水平，就如铜镜愈磨愈亮，要是一只纸糊灯笼呢？用三五次就破了。
经典所以经得起重复，原因有三：一是达到了空前的高度；二是有绝后的效果；三是上升到了理性，有长远的指导意义。
经典不怕后人重复，但重复前人却造不成经典。
文化的发展总是一层一层，积累而成。
在这个积累过程中要有个性，能占一席之地必得有新的创造。
唐诗、宋词、元曲，书法的欧、颜、柳、赵，王羲之的行书、宋徽宗的瘦金书都是中国文学艺术史上的经典。
因为在这之前没有过，实现了“空前”，有里程碑的效果。
经典又是绝后的，你可以重复它、超越它，但不能复制它。
后人时时的想起、品味、研究经典的目的是为了吸收借鉴它，以便去创造自己新的经典。
齐白石谈到别人学他的画说：“学我者生，像我者死。
”每一个经典都有它那个时代、环境及创造者的个性烙印。
你只能创造你自己的高峰。
唯其这种“绝后”性，才使它高标青史，成为永远的经典。
经典所以总能让人重复、不忘、总要提起，是因为它对后人有启示和指导价值。
凡经典都超出了当时实践的范围而有了理性的意义，有哲理的内涵，唯理性才可以指导以后的实践。
只有理性的东西才经得起一遍一遍地挖掘、印证，而它又总能在新的条件下释放出新的能量。
范仲淹说：“先天下之忧而忧，后天下之乐而乐。
”司马迁说：“人总有一死，或重于秦山，或轻于鸿毛。
”这都是永远的经典，早超出了当时的具体所指而有了哲理的永恒。
就是达芬奇的《蒙娜丽莎》的微笑，小提琴曲《梁祝》中爱的旋律，还有毕加索油画中的哲理，张旭狂草中的张力也都远远超出自身的艺术价值而有了生命的启示。

So when he moved to Rajasthan's Alwar district in 1985, he was interested in curing not just his people, but also the region's ecosystem.Singh noticed that most villagers had left their homes after the local Arvari River had dried up, and the only people who remained were either too old or too poor to move elsewhere. Singh, driven by a strong desire to help the villagers, took on the task of bringing water back to those lands.For two years, Singh worked tirelessly, building johads (rainwater storage tanks built with stone, dirt, or whatever materials are available) and checking dams that didn't result in much success. Local elders laughed at him, but he continued working with enthusiasm. And his enthusiasm proved infectious-seeing he was sincere in wanting to help bring water back to their lands, the locals soon began to give money and offer suggestions on appropriate locations to build more dams and johads.Finally his strategy worked. It wasn't long before the Arvari River came back to life, along with four other rivers. People who had abandoned the districts slowly began to move back home, returning to their traditional way of life.Inspired by his success, Singh runs a non-profit organization called Tarun Bharat Sangh (TBS), through which he helps thousands of people solve problems of water shortage. Since the 1980s, TBS has built over 4,500 johads that collect rainwater in 850 villages in 11 districts in India.4. What did Rajendra Singh do after moving to Alwar district?A.

Which words can be used to describe Singh?A. Brave and generous.B. Caring and determined.C. Stubborn and tough.D. Creative and broad-minded.7. What can we know about Tarun Bharat Sangh?A. It is funded by the rich local citizens.B. It is founded to support Singh's medical research.C. It enables many villagers to gain easier access to water.D. It calls on all Indians to protect their living environment.【写作训练】请翻译下列句子1. 我常常在年初为每一学科设立目标。

【新课标卷地区选做】一、文言文阅读（湖南岳阳·二模）阅读下面的文言文，完成下面小题。
文本一：子昂上言①：陛下方兴大化，而太学久废，堂皇埃芜，《诗》《书》不闻，明诏尚未及之，愚臣所以私恨也。
太学者，政教之地也，君臣上下之取则也，俎豆揖让之所兴也，天子于此得贤臣焉。
今委而不论，虽欲睦人伦兴治纲失之本而求之末不可得也。
“君子三年不为礼，礼必坏；三年不为乐，乐必崩”，奈何为天下而轻礼乐哉？愿引胄子使归太学，国家之大务不可废已。
（选自《新唐书·陈子昂传》，有删改）文本二：庚子秋，同被诏校《唐书》新本，见史策伯玉与傅弈、吕才同传，谓伯玉以王者之术说武曌，故《赞》贬之曰：“子昂之于言，其聋瞽欤！”呜呼，甚哉！其不探伯玉之为《政理书》之深意也。
明堂太学②，在昔帝王所以恢大教化之地，自非右文好治之主，为之犹愧无以称其举，岂淫艳荒惑、险刻残诐妇人之所宜与乎？缘事警奸，立文矫僭，伯玉之言，有味乎其中矣。
彼傅、吕者，本好历数才技之书，但能略领大体，颛务记览，以济其末学，讵可引伯玉而为之等夷耶？杜子美、韩退之，唐之伟人也。
杜云：“终古立忠义，《感遇》有遗篇。
”韩云：“国朝盛文章，子昂始高蹈。
”其推尚伯玉之功也如此。
后人或以己见而遽抑之，人之材识，信夫有相绝者矣。
同当时尝欲具疏于朝廷，以辨伯玉之不然，会除外官，不果。
癸卯春，伯玉县人、金华道士喻拱之过门，言其邑令庞君子明于本观陈公读书台旧基，构大屋四楹，题之曰“拾遗亭”。
栋宇宏豁，轩楹虚显，步倚眺听，依然风尚，将记其实，愿烦执事。
同曰：“伯玉，同之郡人也。
昔不幸而死于贼简之手，心常悼之矣。
今不幸而不得列于佳传，是故恳恳欲为之伸地下之枉耳。
记此何敢妄！”遂述前事，使揭于亭上，聊以阐独坐之幽。
其山川之胜，登临之美，今古不易，有子美之诗在焉。
（选自文同《拾遗亭记》，有删改）【注】①子昂，陈子昂，字伯玉，曾任右拾遗。
这里陈子昂向武后（武则天，武曌）上书进言。
②明堂，古代帝王宣明政教、举行大典的地方。

14．(6分)①要花轿早有打算②改装花轿心灵手巧③出租花轿善于经营，贤惠体贴12．本文用不少笔墨写牛，这对环境描写和人物刻画各有什么作用？(6分)【答案】牛不肯挪动半步的恐惧和溜索时流泪发抖：(1)侧面表现怒江峡谷的高峻险恶；(2)与“我”“战战兢兢”互相映衬；又与领队及汉子的勇敢无畏形成反衬。
13．文中写领队比较分散，请统观全文，简要分析领队形象。
(6分)【答案】(1)“懒懒”地说话、“稳稳”地坐在马上：表现他在怒江天险前的从容不迫，胸有成竹；(2) 敲一敲溜索，“吼”我过江：表现他认真负责，关爱部下；(3) 瞟一眼，问一声：表现他受人尊敬，与手下配合默契；(4)一声唿哨、最后一个过溜索：表现他的英雄气概，粗犷豪迈。
第二卷诗歌鉴赏1.阅读《江雪》（柳宗元），简要地分析“蓑笠翁”的形象。
江雪千山鸟飞绝，万径人踪灭。
孤舟蓑笠翁，独钓寒江雪。
【参考答案】诗歌刻画了一位清高孤傲的不畏风霜严寒的老渔翁形象。
通过读诗，可见前两句描绘出一幅广阔、寒冷、寂静的环境。
在这样的一个环境中，那位老渔翁不怕天寒雪大，而忘掉一切，专心钓鱼，形体虽然孤独，性格却显得格外清高孤傲，甚至有点凛然不可侵犯似的。
这个被幻化了、美化了的渔翁形象，恰是实际生活中的柳宗元本人思想感情的寄托与写照。
2. 阅读《题李凝幽居》（贾岛），简要地分析“李凝”的形象。
题李凝幽居闲居少邻并，草径入荒园。
鸟宿池边树，僧敲月下门。
过桥分野色，移石动云根。
暂去还来此，幽期不负言。
【参考答案】本诗通过描写李凝居住的荒僻,清幽,刻画了一个过着悠闲、宁静生活的隐士形象。
首联诗人用“少邻”“草径”“荒园”的环境描写，暗示其隐士身份。
颔联的以动衬静，颈联的归路所见，均表现李凝居处的清幽，烘托出李凝生活的悠闲、宁静。

Boys come in different sizes, weights, and colors, but all boys have the same belief: to enjoy every second of every minute of every hour of every day and to fill the air with noise until the adult males send them off to bed at night.Boys are found everywhere--on top of under, inside of, climbing on, swinging from, running around, or jumping to. Mothers spoil them, little girls hate them, older sisters and brothers love them, and God protects them. A boy is TRUTH with dirt on its face, BEAUTY with a cut on its finger, WISDOM with chocolate in its hair, and the HOPE of the future with a snake in its pocket.When you are busy, a boy is a trouble-maker and a noise. When you want him to make a good impression, his brain turns to jelly or else he becomes a wild creature destroying the world and himself with it.A boy is a mixture--he has the stomach of a horse, the digestion of stones and sand, the energy of an atomic bomb, the curiosity of a cat, the imagination of a superman, the shyness of asweet girl, the brave nature of a bull, the violence of a firecracker (鞭炮), but when you ask him to make something, he has five thumbs on each hand.He likes ice cream, knives, saws, Christmas, comic books, woods, water (in its natural habitat), large animals, Dad, trains, Saturday mornings, and fire engines. He is not much for Sunday schools, company, schools, books without pictures, music lessons, neckties, barbers, girls, overcoats, adults, or bedtime.Nobody else is so early to rise, or so late to supper. Nobody else gets so much fun out of trees, dogs, and breezes. Nobody else can put into one pocket a rusty knife, a half-eaten apple, a three-foot rope, six cents and some unknown things.A boy is a magical creature--he is your headache but when you come home at night with only destroyed pieces of your hopes and dreams, he can mend them like new with two magic words, "Hi, Dad!"1. The whole passage is in a tone of ________.A. humor and affectionB. anger and disappointmentC. hope and expectationD. confidence and imagination2. What's the meaning of the underlined sentence?A. He has altogether five fingers.B. He is slow, foolish and clumsy.C. He becomes clever and smart.D. He cuts his hand with a knife.3. According to the writer, boys appreciate everything in the following except ________.A. ice creamB. comic booksC. Saturday morningsD. Sunday schools4. What does the writer feel about boys?A. He feels curious about their noise.B. He is tired of these creatures.C. He is amazed by their naughtiness.D. He feels unsafe staying with them.DIn colleges around the country, most students are also workers.The reality of college can be pretty different from the images presented in movies and television. Instead of the students who wake up late, party all the time, and study only before exams, many colleges are full of students with pressing schedules of not just classes and activities, but real jobs, too.This isn’t a temporary phenomenon. The share of working students has been on the rise since the 1970s, and one-fifth of students work year round. About one-quarter of those who work while attending school have both a full-course load and a full-time job. The arrangement can help pay for tuition (学费) and living costs, obviously. And there’s value in it beyond the direct cause: such jobs can also be critical for developing important professional and social skills that make it easier to land a job after graduation. With many employers looking for students with already-developed skill sets, on-the-job training while in college can be the best way to ensure a job later on.But it’s not all upside. Even full-time work may not completely cover the cost of tuition and living expenses. The study notes that if a student worked a full-time job at the federal minimum wage, they would earn just over $15,000 each year, certainly not enough to pay for tuition, room, and board at many colleges without some serious financial aid. That means that though they’re sacrificing time away from the classroom, many working students will still graduate with at leastsome debt. And working full time can reduce the chance that students will graduate at all, by cutting into the time available for studying and attending classes.There is little reward for attending but not finishing college. Students who end up leaving school because of difficulty in managing work and class are likely to find themselves stuck in some of the same jobs they might have gotten if they hadn’t gone at all. The difficulty of working too much while in school can create a cycle that pushes students further into debt without receiving any of the financial or career benefits.5. According to the passage, the reality of college students is that ________.A. they throw parties a lotB. they stay up late every nightC. they work besides attending classesD. they pay no attention to exams6. What is the indirect cause of an increasing number of working students?A. The need of developing social networks.B. The lack of summer jobs for young adults.C. The chance of finding a job after graduation.D. The expenses of high tuition and living costs.7. We can learn from the passage that _________.A. working students are more likely to finish collegeB. students can cover their college expenses through workingC. students receive a huge reward for managing work and classD. working while attending school may not help students get career benefits8. What is the best title for the passage?A. The Difficulties of Landing a JobB. The Struggle of Work-School BalanceC. The Reward of Working While StudyingD. The Images of Working College Students【作文训练】一、请把下列句子翻译成英语(括号中的提示词必须用，且不能更改词性，否则不能得分)。
