2020年普通高等学校招生全国统一考试[新高考全国卷Ⅰ]试题及答案解析

2020年普通高等学校招生全国统一考试[新高考全国卷Ⅰ]试题及答案解析
沿革地理研究的内容关系到国计民生,也是治学的基础,例如历史地名的注释和考证、历代疆域和政区的变迁、黄河等水道的变迁,特别是与儒家经典和传统正史的理解有关的地理名称和地理知识,都被看成是治学的基本功。沿革地理的成就在清代中期达到高峰,很多乾嘉学者致力于此。
但是沿革地理并不等于历史地理学,二者不仅有量的不同,而且有质的区别。就研究内容而言,前者主要是疆域政区、地名和水道的变迁,后者却涉及地理学的各个分支。就研究的性质而言,前者一般只是对现象的描述和复原,很少涉及变化的原因,后者则不仅要复原各种以往的地理现象,而且要寻找它们变化发展的原因,探索背后的规律。由于产生于西方的现代地理学在中国的传播很迟,加上我国缺乏全面系统的科学基础,中国沿革地理虽然早已成为专门学问,却一直未形成新的学科。历史地理学则有自己独立的学科体系和理论,是现代地理学的一部分。
在这个城里,有个家的人真是有福啊。他们还能够像四百年前的祖先们那样安居乐业,不必操心左邻右舍的德行,都是世交啦。有一位绕过曲曲弯弯的小巷,提着在龙井市场买来的水淋淋的草芽(一种建水特有的水生植物,可食,滚油翻炒数秒起锅,甜脆)、莴笋、茄子、青椒、豆腐、毛豆、肉糜、茭瓜……一路上寻思着要怎么搭配,偶尔向世居于此的邻居熟人搭讪,彼此请安。磨磨蹭蹭到某个装饰着斗拱飞檐门头的大门前(两只找错了窝的燕子拍翅逃去),咯吱咯吱地推开安装着铜质狮头门环的双开核桃木大门,抬脚跨过门槛。绕过照壁,经过几秒钟的黑暗,忽然光明大放,回到了曾祖父建造的花香鸟语、阳光灿烂的天井。从供销社退休已经三十年的祖母正躺在一把支在天井中央的红木躺椅上,借着一棵百年香樟树的荫庇瞌睡呢。
成书于公元1世纪的《汉书·地理志》对见于典籍记载的重要地理要素,包括古国、历史政区、地名、河流、山岭、古迹等都做了记载和简要考证,并不局限于西汉一朝。作者班固比较充分地利用已有的地理记载和地理研究成果,使得中国历史地理学研究初具雏形。同样,成书于公元6世纪的《水经注》也从传世的数百种地理著作中搜集整理了大量史料,并做了深入的考证和研究。今天,我们之所以还能知道先秦的某一个地名在现在的什么地方,能知道秦汉以降的疆域范围,能够大致了解黄河早期的几次改道,都离不开这两种著作。

2021全国新高考Ⅰ卷语文试题及参考答案

2021全国新高考Ⅰ卷语文试题及参考答案2021年普通高等学校招生全国统一考试语 文本试卷共10页,23小题,满分150分。

考试用时150分钟。

一、现代文阅读(35分)(一)现代文阅读【(本题共5小题,19分)阅读下面的文字,完成1~5题。

材料一:十八世纪德国学者莱辛的《拉奥孔》是近代诗画理论文献中第一部重要著作。

从前人们相信诗画同质,直到菜辛才提出丰富的例证,用动人的雄辩,说明诗画并不同质。

据传说,希腊人为了夺回海伦,举兵围攻特洛伊城,十年不下。

最后他们佯逃,留着一匹腹内埋伏精兵的大木马在城外,特洛伊人看见木马,把它移到城内。

典祭官拉奥孔当时极力劝阻,说留下木马是希腊人的诡计。

他这番忠告激怒了偏心于希腊人的天神。

当拉奥孔典祭时,河里就爬出两条大蛇,把拉奥孔和他的两个儿子一齐绞死了。

这是罗马诗人维吉尔《伊尼特》第二卷里最有名的一段。

十六世纪在罗马发现的拉奥孔雕像似以这段史诗为蓝本。

莱辛拿这段诗和雕像互较,发现几个重要的异点。

因为要解释这些异点,他才提出诗画异质说。

据史诗,拉奥孔在被捆时放声号叫;在雕像中他的面孔只表现一种轻微的叹息,具有希腊艺术所特有的恬静与肃穆。

为什么雕像的作者不表现诗人所描写的号啕呢?希腊人在诗中并不怕表现苦痛,而在造型艺术中却永远避免痛感所产生的面孔筋肉挛曲的丑状。

在表现痛感之中,他们仍求形象的完美。

雕塑《拉奧孔》其次,据史诗,那两条长蛇绕腰三圈,绕颈两圈,而在雕像中它们仅绕着两腿。

因为作者要从全身筋肉上表现出拉奥孔的苦痛,如果依史诗,筋肉方面所表现的苦痛就看不见了。

同理,雕像的作者让拉奥孔父子赤裸着身体,虽然在史诗中拉奥孔穿着典祭官的衣服。

莱辛推原这不同的理由,作这样一个结论:“图画和诗所用的模仿媒介或符号完全不同,图画用存于空间的形色,诗用存于时间的声音。

……全体或部分在空间中相并立的事物叫作‘物体’,物体和它们的看得见的属性是图画的特殊题材。

全体或部分在时间上相承续的事物叫作‘动作’,动作是诗的特殊题材。

一、现代文阅读(一)论述文本阅读(本题共3小题,9分)阅读下面的文字,完成1~3题。

社会是由众多家庭组成的,家庭和谐关乎社会和谐。

要在家庭中建立一种和谐的关系,就需要有家庭伦理。

中国自古以来就有维护家庭关系的种种伦理规范,它们往往体现在各种“礼”之中、从《礼记》中可以看到各种礼制的记载,如婚丧嫁娶,这些都包含着各种家庭伦理规范,而要使这些规范成为一种社会遵守的伦理,就要使“礼”制度化。

在中国古代,“孝”无疑是家庭伦理中最重要的观念。

《孝经》中有孔子的一段话:“夫孝,天之经也,地之义也,民之行也。

”这是说“孝”是“天道”常规,是“地道”通则,是人们遵之而行的规矩,为什么“孝”有这样大的意义?这与中国古代宗法制有关。

中国古代社会基本上是宗法性的农耕社会,家庭不仅是生活单位,而且是生产单位,要较好地维护家庭中长幼尊卑的秩序,使家族得以顺利延续,必须有一套维护当时社会稳定的家庭伦理规范。

这种伦理规范又必须是一套自天子至庶人都遵守的伦理规范,这样社会才得以稳定。

“孝”成为一种家庭伦理规范,并进而成为社会的伦理制度,必有其哲理上的根据。

《郭店楚简·成之闻之》中说:“天登大常,以理人伦,制为君臣之义,作为父子之亲,分为夫妇之辨。

”理顺君臣、父子、夫妇的关系是“天道”的要求,君子以“天道”常规处理君臣、父子、夫妇伦理关系,社会才能治理好。

所以,“人道”与“天道”是息息相关的。

“孝”作为一种家庭伦理的哲理根据就是孔子的“仁学”,以“亲亲”(爱自己的亲人)为基点,扩大到“仁民”,以及于“爱物”,基于孔子的“仁学”,把“孝”看成是“天之经”“地之义”“人之行”是可以理解的。

对文学艺术创作者来说,或早或晚,都会遭遇到这个问题—为谁创作、为谁立言,强调:“文学艺术创造、哲学社会科学研究首先要搞清楚为谁创作、为谁立言的问题,这是一个根本问题。

人民是创作的源头活水,只有扎根人民,创作才能获得取之不尽、用之不竭的源泉。

”目前,文艺界普遍认识到,只有与身处的时代积极互动,深刻回应时代重大命题才会获得艺术创作的蓬勃生机。

然而,在创作实践中,还有许多作家、艺术家困惑于现实如此宏大丰富,以至于完全超出个人的认识和表现能力。

我们常常听到这样的说法现实太精彩了,它甚至远远走到了小说家想象力的前面。

是的,我们有幸生活在这样个日新月异的时代,随时发生着习焉不察而影响深远的变化。

这就为作家、艺术家观察现实、理解生活带来巨大困难。

对于他们而言,活灵活现地描绘出生活的表象,大约是不难的,难就难在理解生活复杂的结构,理解隐藏在表象之下那些更深层的东西。

那么这“更深层的东西”是什么呢?去过天安门广场的朋友一定会对矗立在广场上的人民英雄纪念碑印象深刻,许多人都背得出上面的碑文—“三年以来,在人民解放战争和人民革命中牺牲的人民英雄们永垂不朽!三十年以来,在人民解放战争和人民革命中牺牲的人民英雄们永垂不朽!由此上溯到一千八百四十年,从那时起,为了反对内外敌人,争取民族独立和人民自由幸福,在历次斗争中牺牲的人民英雄们永垂不朽!”在新中国成立70周年的今天,再次诵读这段话,我们就会意识到,这改天换地的宏伟现实是人民创造的,人民当之无愧是时代的英雄,是历史的创造者。

只有认识到人民的主体地位,才能感受到奔涌的时代浪潮下面深藏的不竭力量,才有可能从整体上把握一个时代,认识沸腾的现实。

认识人民创造历史的主体地位,是为了从理性和情感上把自己放到人民中间,是为了解决我是谁、我属于谁的问题。

AGrading Policies for Introduction to LiteratureGrading Scale90-100, A; 80-89, B; 70-79, C; 60-69, D; Below 60, E.Essays(60%)Your four major essays will combine to form the main part of the grade for this course: Essay 1 =10%; Essay 2=15%; Essay 3=15%; Essay 4=20%Group Assignments(30%)Students will work in groups to complete four assignments(作业)during the course. All the assignments will be submitted by the assigned date through Blackboard, our online learning and course management system.Daily Work/In-Class Writings and Tests/Group Work/Homework(10%)Class activities will vary from day to day, but students must be ready to complete short in-class writings or tests drawn directly from assigned readings or notes from the previous class' lecture/discussion, so it is important to take careful notes during class. Additionally, from time to time I will assign group work to be completed in class or short assignments to be completed at home, both of which will be graded.Late WorkAn essay not submitted in class on the due date will lose a letter grade for each class period it is late. If it is not turned in by the 4th day after the due date, it will earn a zero. Daily assignments not completed during class will get a zero. Short writings missed as a result of an excused absence will be accepted.21. Where is this text probably taken from?A. A textbook.B. An exam paper.C. A course plan.D. An academic article.22. How many parts is a student's final grade made up of?A. Two.B. Three.C. Four.D. Five.23. What will happen if you submit an essay one week after the due date?A. You will receive a zero.B. You will lose a letter grade.C. You will be given a test.D. You will have to rewrite it.BLike most of us, I try to be mindful of food that goes to waste. The arugula(芝麻菜)was to make a nice green salad, rounding out a roast chicken dinner. But I ended up working late. Then friends called with a dinner invitation. I stuck the chicken in the freezer. But as days passed, the arugula went bad. Even worse, I had unthinkingly bought way too much; I could have made six salads with what I threw out.In a world where nearly 800 million people a year go hungry, "food waste goes against the moral grain," as Elizabeth Royte writes in this month's cover story. It's jaw-dropping how much perfectly good food is thrown away—from “ugly"(but quite eatable)vegetables rejected by grocers to large amounts of uneaten dishes thrown into restaurant garbage cans.Producing food that no one eats wastes the water, fuel, and other resources used to grow it. That makes food waste an environmental problem. In fact, Royte writes, "if food waste were a country, it would be the third largest producer of greenhouse gases in the world."If that's hard to understand, let's keep it as simple as the arugula at the back of my refrigerator. Mike Curtin sees my arugula story all the time —but for him, it's more like 12 bones of donated strawberries nearing their last days. Curtin is CEO of DC Central Kitchen in Washington, D.C., which recovers food and turns it into healthy meals. Last year it recovered more than 807,500 pounds of food by taking donations and collecting blemished(有瑕疵的)produce that otherwise would have rotted in fields. And the strawberries? V olunteers will wash, cut, and freeze or dry them for use in meals down the road.Such methods seem obvious, yet so often we just don't think. "Everyone can play a part in reducing waste, whether by not purchasing more food than necessary in your weekly shopping or by asking restaurants to not include the side dish you won't eat," Curtin says.24. What does the author want to show by telling the arugula story?A. We pay little attention to food waste.B. We waste food unintentionally at times.C. We waste more vegetables than meat.D. We have good reasons for wasting food.25. What is a consequence of food waste according to the test?A. Moral decline.B. Environmental harm.C. Energy shortage.D. Worldwide starvation.26. What does Curtin's company do?A. It produces kitchen equipment.B. It turns rotten arugula into clean fuel.C. It helps local farmers grow fruitsD. It makes meals out of unwanted food.27. What does Curtin suggest people do?A. Buy only what is needed.B. Reduce food consumption.C. Go shopping once a week.D. Eat in restaurants less often.CThe elderly residents(居民)in care homes in London are being given hens to look after to stop them feeling lonely.The project was dreamed up by a local charity(慈善组织)to reduce loneliness and improve elderly people's wellbeing, It is also being used to help patients suffering dementia, a serious illness of the mind. Staff in care homes have reported a reduction in the use of medicine where hens are inuse.Among those taking part in the project is 80-year-old Ruth Xavier. She said: “I used to keep hens when I was younger and had to prepare their breakfast each morning before I went to school."I like the project a lot. I am down there in my wheelchair in the morning letting the hens out and down there again at night to see they've gone to bed."It's good to have a different focus. People have been bringing their children in to see the hens and residents come and sit outside to watch them. I'm enjoying the creative activities, and it feels great to have done something useful."There are now 700 elderly people looking after hens in 20 care homes in the North East, and the charity has been given financial support to roll it out countrywide.Wendy Wilson, extra care manager at 60 Penfold Street, one of the first to embark on the project, said: "Residents really welcome the idea of the project and the creative sessions. We are looking forward to the benefits and fun the project can bring to people here."Lynn Lewis, director of Notting Hill Pathways, said: "We are happy to be taking part in the project. It will really help connect our residents through a shared interest and creative activities."28. What is the purpose of the project?A. To ensure harmony in care homes.B. To provide part-time jobs for the aged.C. To raise money for medical research.D. To promote the elderly people's welfare.29. How has the project affected Ruth Xavier?A. She has learned new life skills.B. She has gained a sense of achievement.C. She has recovered her memory.D. She has developed a strong personality.30. What do the underlined words "embark on" mean in paragraph 7?A. Improve.B. Oppose.C. Begin.D. Evaluate.31. What can we learn about the project from the last two paragraphs?A. It is well received.B. It needs to be more creative.C. It is highly profitable.D. It takes ages to see the results.DHuman speech contains more than 2,000 different sounds, from the common "m" and "a" to the rare clicks of some southern African languages. But why are certain sounds more common than others? A ground-breaking, five-year study shows that diet-related changes in human bite led to new speech sounds that are now found in half the world's languages.More than 30 years ago, the scholar Charles Hockett noted that speech sounds called labiodentals, such as "f" and "v", were more common in the languages of societies that ate softer foods. Now a team of researchers led by Damián Blasi at the University of Zurich, Switzerland, has found how and why this trend arose.They discovered that the upper and lower front teeth of ancient human adults were aligned(对齐), making it hard to produce labiodentals, which are formed by touching the lower lip to the upper teeth. Later, our jaws changed to an overbite structure(结构), making it easier to produce such sounds.The team showed that this change in bite was connected with the development of agriculture in the Neolithic period. Food became easier to chew at this point. The jawbone didn't have to do as much work and so didn't grow to be so large.Analyses of a language database also confirmed that there was a global change in the sound of world languages after the Neolithic age, with the use of "f" and "v" increasing remarkably during the last few thousand years. These sounds are still not found in the languages of many hunter-gatherer people today.This research overturns the popular view that all human speech sounds were present whenhuman beings evolved around 300,000 years ago. "The set of speech sounds we use has not necessarily remained stable since the appearance of human beings, but rather the huge variety of speech sounds that we find today is the product of a complex interplay of things like biological change and cultural evolution," said Steven Moran, a member of the research team.32. Which aspect of the human speech sound does Damián Blasi's research focus on?A. Its variety.B. Its distribution.C. Its quantity.D. Its development.33. Why was it difficult for ancient human adults to produce labiodentals?A. They had fewer upper teeth than lower teeth.B. They could not open and close their lips easily.C. Their jaws were not conveniently structured.D. Their lower front teeth were not large enough.34. What is paragraph 5 mainly about?A. Supporting evidence for the research results.B. Potential application of the research findings.C. A further explanation of the research methods.D. A reasonable doubt about the research process.35. What does Steven Moran say about the set of human speech sounds?A. It is key to effective communication.B. It contributes much to cultural diversity.C. It is a complex and dynamic system.D. It drives the evolution of human beings.第二节(共5小题;每小题2.5分,满分12.5分)阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。

rates.②When this practice first started decades ago, it was usually limited to freshmen, to give them a second chance to take a class in their first year if they struggled in their transition to college-level courses. ③But now most colleges, save for many selective campuses, allow all undergraduates, and even graduate students, to get their low grades forgiven.①Collegeofficialstendtoemphasizethatthegoalofgradeforgivenessislessaboutthegrade itself and more about encouraging students to retake courses critical to their degree program and

courses or master the content that allows them to graduate ontime.”①That said, there is a way in which grade forgiveness satisfies colleges’ own needs as well.② For public institutions, statefunds are sometimes tied partly to their success on metrics such as graduation rates and student retention—so better grades can, by boosting figures like those, mean more money. ③And anything that raises GPAs will likely make students—who, at the end of the day, are paying the bill — feel they’ve gotten a better value for their tuition dollars, which is another big concern for

What makes humanshumans?”①What is being called artificial general intelligence, machines that would imitate the way humans think, continues to evade scientists. ②Yet humans remain fascinated by the idea of robots that would look, move, and respond like humans, similar to those recently depicted on popular sci- fi TV series such as “Westworld” and “Humans”.①Just how people think is still far too complex to be understood, let alone reproduced, says David Eagleman, a Stanford University neuroscientist. ②“We are just in a situation where there are no good theories explaining what consciousness actually is and how you could ever build a machine to get there.”①But that doesn’t mean crucial ethical issues involving AI aren’t at hand. ②The coming use of autonomous vehicles, for example, poses thorny ethical questions. ③Human drivers sometimes must make split-second decisions. ④Their reactions may be a complex combination of instant reflexes,inputfrompastdrivingexperiences,andwhattheireyesandearstelltheminthatmoment.⑤AI “vision” today is not nearly as sophisticated as that of humans. ⑥And to anticipate every imaginable driving situation is a difficult programming problem.①Whenever decisions are based on masses of data, “you quickly get into a lot of ethical questions,” notes Tan Kiat How, chief executive of a Singapore-based agency that is helping the government develop a voluntary code for the ethical use of AI. ②Along with Singapore, other governments and mega-corporations are beginning to establish their own guidelines. ③Britain is setting up a data ethics center. ④India released its AI ethics strategy this spring.①OnJune7Googlepledgednotto“designordeployAI”thatwouldcause“overallharm,”or todevelopAI-directedweaponsoruseAIforsurveillancethatwouldviolateinternationalnorms.②It also pledged not to deploy AI whose use would violate international laws or human rights.①While the statement is vague, it represents one starting point. ②So does the idea that decisions made by AI systems should be explainable, transparent, and fair.①To put it another way: How can we make sure that the thinking of intelligent machines reflectshumanity’shighestvalues?②Onlythenwilltheybeusefulservantsandnot Frankenstein’s out-of-control monster.31.Mary Shelley’s novel Frankenstein is mentioned

collect sales tax on online purchases already. ②Now, rivals will be charging sales tax where they hadn’t before. ③Big chains have been collecting sales tax nationwide because they typically have physical stores in whatever state a purchase is being shipped to. ④, with its network of warehouses, also collects sales tax in every state that charges it, though third-party sellers whouse the site

If we readjust our view of arguments—from a verbal fight or tennis game to a reasoned exchange through which we all gain mutual respect and understanding—then we change the very nature of what it means to “win” an argument.B.Inhis1936work HowtoWinFriendsandInfluencePeople,DaleCarnegiewrote:“Thereisonly one way…to get the best of an argument—and that is to avoid it.” This aversion to arguments is common, but it depends on a mistaken view of arguments that causes profound problems for our personal and social lives—and in many ways misses the point of arguing in the firstplace.C.Noneofthesewillbeeasy,butyoucanstartevenifothersrefuseto.Nexttimeyoustateyourposition, formulate an argument for what you claim and honestly ask yourself whether your argument is any good.

Raise objections and listen carefully to their replies.D.Of course, many discussions are not so successful. Still, we need to be careful not to accuse opponents of bad arguments too quickly.

Write your answers on the ANSWER SHEET. (10 points)It was only after I started to write a weekly column about the medical journals, and began to read scientific papers from beginning to end, that I realised just how bad much of the medical literature frequently was. I came to recognise various signs of a bad paper: the kind of paper that purports to show that people who eat more than one kilo of broccoli a week were 1.17 timesmorelikely than those who eat less to suffer late in life from pernicious anaemia. (46) There is a greatdeal of this kind of nonsense in the medical journals which, when taken up by broadcasters and thelay press, generates both health scares and short-lived dietary enthusiasms.Why is so much bad science published? A recent paper, titled “The Natural Selection of Bad Science”,publishedontheRoyalSociety’sopensciencewebsite,attemptstoanswerthisintriguing and important question. It says that the problem is not merely that people do bad science, but that our current system of career advancement positively encourages it.

G. Carnegie would be right if arguments were fights, which is how we often think of them. Like physical fights, verbal fights can leave both sides bloodied. Even when you win, you end up no better off. Your prospects would be almost as dismal if arguments were even just competitions—like, say, tennis games. Paris of opponents hit the ball back and forth until one winner emerges from all who entered. Everybody else loses. This kind of thinking is why so many people try to avoid arguments, especially about politics and religion.43. E. There is a better way to win arguments. Imagine that you favor increasing the minimum wage in our state, and I do not. If you yell, “Yes,” and I yell. “No,” neither of us learns anything. We neither understand nor respect each other, and we have no basis for compromise or cooperation. In contrast, suppose you give a reasonable argument: that full- time workers should not have to live in poverty. Then I counter with another reasonable argument: that a higher minimum wage will force businesses to employ fewer people for less time. Now we can understand each other’s positions and recognize our shared values, since we both care about needy workers.44. D. Of course, many discussions are not so successful. Still, we need to be careful not to accuse opponents of bad arguments too quickly. We need to learn how to evaluate them properly. A large part of evaluation is calling out bad arguments, but we also need to admit good arguments by opponents and to apply the same critical standards to ourselves. Humility requires you to recognize weaknesses in your own arguments and sometimes also to accept reasons on the opposite side.45. A. These tools can help you win every argument—not in the unhelpful sense of beating your opponents but in the better sense of learning about the issues that divide people, learning why they disagree with us and learning to talk and work together with them.

and his compatriots extolled the romantic spirit.47.A.To Ahab,the whale is either an evil creature itself or the agent of an evil force that controls the universe,or perhaps both.B.To Ishmale,the whale is an astonishing force,an immense power,which defies rational explanation due to a sense of mystery it carries.It is beautiful,but malignant at the same time.It also represents the tremendous organic vitality of the universe,for it has a life force that surges onward irresistibly, impervious to the desires or wills of men.C.As to the reader, the whale can be viewed as a symbol of the physical limits that life imposes upon man.It may also be regarded as a symbol of nature, or an instrument of God's vengeance upon evil man.In general,the multiplicity and ambivalence of the symbolic meaning of the whale is such that it becomes a source of intense speculation, an object or profound curiosity for the reader.48.A.The Oversoul is believed to be an all-pervading power for goodness,omnipresent and omnipotent from which all things come and of which all are a part.It exists in nature and man alike and constitutes the chief element of the universe.B.According to Emerson,it is a supreme reality of mind, a spiritual unity of all beings, and a religion regarded as an emotional communication between an individual soul and the universal Over-soul of which it is a part.C.He holds that intuition is a more certain way of knowing than reason and that the mind could intuitively perceive the existence of the Oversoul and of certain absolutes.Ⅳ.Topic Discussion (20 points in all, 10 for each)49.a.Neoclassicists upheld that artistic ideals should be order,logic,restrained emoticon and accuracy,and that literature,should be judged in terms of its service to humanity,and thus,literary expressions should be of proportion,unity,harmony and grace.Pope's An Essay on Criticism advocates grace,wit (usually though satire/humour),and simplicity in language(and the poem itself is a demonstration of those ideals,too);Fielding's Tom Jones helped establish the form of novel;Gray's “Elegy Written in a Country Churchyard' displays elegance in style,unified structure,serious tone and moral instructions.b.Romanticists tended to see the individual as the very center of all experience,including art,and thus,literary work should be “spontaneous overflow of strong feelings,〞and no matter how fra gmentary those experiences were (Wordsworth's “I Wandered Lonely as a Cloud,〞or “The Solitary Reaper,) or Coleridge's “Keble Khan〞),the value of the work lied in the accuracy of presenting those unique feelings and particular attitudes.c.In a word, Neoclassicism emphasized rationality and form but Romanticism attached great importance to the individual's mind (emotion, imagination, temporary experience…)50.A.Mark Twain's novel The Adventures of Huckleberry Finn is a Sequa to The Adventures of Tom Sawyer.The Story takes place along the Mississippi River before the Civil War in the United States, around 1850.Along the river, floats a small raft, with two people on it; One is an ignorant,uneducated black slave named Jim and the other is little uneducated outcast white boy about the age of thirteen, called Huckleberry Finn or Huck Finn.The novel relates the story of the escape of Jim from slavery and ,more important, how Huck Finn, floating along with Jim and helping him as best he could, changes his mind ,his prejudice, about Black people, and comes to accept Jim as a man and as a close friends as well.During their journey, they experience a series of adventures:coming across two frauds, the “Duke〞and the “King〞,witnessing the lynching and murder of a harmless drunkard, being lost in a fog and finally Tom's coming to rescue. B.The theme of the novel may be best summed in a word “freedom〞: Huck wants to escape from the bond of civilization andJim wants to escape from the yoke of slavery.Mark Twain uses the raft's journey down the Mississippi River to express his thematic contrasts between innocence and experience, nature and culture, wilderness and civilizati。
