中国现代文学史复习资料

第一章五四文学革命 1、1917年1月《新青年》刊出胡适的《文学改良刍议》,从“八事”入手(须言之有物、不摹仿古人、须讲究文法、不作无病之呻吟、务去滥调套语、不用典、不讲对仗、不避俗字俗语) 2、1917年2月《新青年》发表陈独秀《文学革命论》,明确提出“三大主义”,陈独秀把晚清以来的文学革命运动推向了高潮。 3、钱玄同在致《新青年》的信中,以语言进化的角度说明白话取代文言的历史必然性,刘半农与钱玄同(化名为王敬轩)在《新青年》上发表了“双簧信”。 4、周作人发表《人的文学》,从人性、人道主义的角度来要求新文学的内容,倡导新文学内容要从“肉”与“灵”的统一中去表现“人”;在另一篇《平民文学》中提出“人生的艺术派主张”,又提出“以真为主,美即在其中”的创作准则。 5、文学革命的实绩最主要在于创作,文学革命带来文学观念、内容、语言载体、形式各方面全面的革新与解放。 【《学衡》派: 1、发起人及时间地点:1922年,南京东南大学的梅光迪、胡先骕、吴宓等创办了《学衡》杂志,因诸人观点态度相近,被称为《学衡》派 2、主张:尊崇中国的古圣贤者,以融贯中西古今的姿态,标榜“昌明国粹,融化新知,以中正之眼光,行批评之职事”,反对新文化运动和文学革命,思想稳健保守,是“穿西装的复古派”。 3、代表作:梅光迪《评提倡新文化者》;吴宓、胡先骕《论新文化运动》《评<尝试集>》】(3)新文化阵营与章士钊《甲寅》上的复古论调的论争。 13、五四文学革命的历史意义: (1)自晚清以来的被压抑着的现代性获得了最大的生机,形成了新的文化与文学观念,开创了新的主题领域与人物形象谱系; (2)五四文学革命全面革新文学语言、文体形式,奠定了20世纪中国文学的基本审美价值取向和多元并存的接受心理基础; (3)五四文学增添了世界维度,建立了中国文学与世界文学的密切关系,自觉的借鉴、吸收外国文学及文化的营养,形成了面向世界而又有本土特点的开放性现代文学; (4)五四形成的现代作家队伍是以后半个多世纪的文学创作的主体力量,这批作家和他们开创的文学内容及形式形成了新的现代传统,这一传统的赓续是文学现代性的基本保证。第二章20年代小说(一) 1、问题小说代表作家:叶绍钧、许地山、冰心、王统照、庐隐等 (1)冰心:“爱的三部曲”《超人》、《烦闷》、《悟》,其中《超人》(1921)标志着冰心对社会问题开出了她的“药方”,这就是“爱的哲学”(爱、童心、自然是“爱的哲学之鼎的三足”)(2)庐隐:中篇《海滨故人》《或人的悲哀》;短篇《丽石的日记》;长篇《象牙戒指》《女人的心》《归雁》《云鸥情书集》《庐隐自传》等,风格感伤,基调悲戚,与郁达夫同为新文学抒情小说开拓者。 (3)王统照:最重要的长篇小说《山雨》(1933) (4)叶绍钧:20年代出版了《隔膜》《城中》等5个短篇小说集;《倪焕之》(1928)是其唯一长篇小说,显示现实主义趋向,被誉为“扛鼎的工作”。 叶绍钧小说以灰色人生的冷静观察和客观描写,表现了写实主义特征。同时与讽刺兼备,是叶绍钧对小市民知识分子用笔的基本特色。 叶绍钧还是现代中国童话的开山者。鲁迅对其评价:“叶绍钧先生的《稻草人》是给中国的童话开出了一条自己的创作的路的。”

中国现代文学史期末准备2

A类问题 ①吴荪甫是半封建半殖民地这一特定历史环境中具有封建性的中国民族资产阶级的一个失败了的英雄形象,他 在几重挤压的环境下为求生存而形成的性格的多重性使得形象有多侧面的立体感:一,吴荪甫具有刚强和软弱这两个方面的性格,似强实弱,外强中干,他有英雄性的一面:在与帝国主义经济侵略的斗争中,表现出果敢、自信法兰西资产阶级式的性格。有发展中国独立的民族工业的雄才大略,有着活跃的生命力,刚毅顽强,果断的铁腕与魄力,更有现代科学管理的经营之才,也有非英雄的自私,怯弱甚至残酷。二,吴荪甫的性格充分显示出民族资产阶级的两重性:一方面对帝国主义、买办资产阶级、封建主义的不满;另一方面对工农运动和革命武装极端恐惧与仇视。一方面对统治阶级的腐败制度与军阀混战的局面不满;另一方面又依靠反动势力镇压工人农民运动它既有被压迫的一面也有压迫者的以一面。两重性使得他处在一个非常微妙的夹缝中,同时也决定了他命运的必然悲剧结局 ②觉慧是封建家庭大胆而勇敢的叛逆者,满怀热情的不成熟的革命者。大胆表现在:他受五四思想影响,以改 造天下为己任,积极参加社会活动,他热爱国家,追求科学与民主,不信神,反对专制主义,具有很强的民主精神,在学校里参加了反对军阀的学潮,和同学一起办反封建的刊物,在家里中,和鸣凤恋爱,支持觉民抗婚,怒斥“捉鬼”闹剧。他极端憎恨这个家庭,第一个冲出封建家庭的牢笼,成为封建家庭的叛逆者,代表着青年人追求真理的道路。幼稚表现在:他以个性解放为武器,对封建家庭的认识是个逐渐的过程,他的思想性格带有“五四”时期一般小资产阶级的知识分子的狂热性的弱点。他并不是彻底树立了无产阶级世界观,彻底背叛地主阶级的英雄,思想仍有少数剥削阶级的东西。觉慧是五四时期具有民主主义觉悟的知识青年形象,旧家庭礼教叛逆者的形象。 ③《日出》话剧剧本,四幕话剧,曹禺作于1935年,曾获《大公报》“文艺奖金”。《日出》是曹禺先生以30年 代初期半殖民地半封建社会中国大都市生活为背景的现实主义力作。《日出》以鲜明的时代性和深广的历史内容在曹禺剧作中居于领衔地位。剧本没有主角,而是以陈白露和方达生为中心,以陈的客厅和三等妓院宝和下处为活动场所,把社会各阶层各色人等的生活展现在观众面前,揭露剥削制度“损不足以奉有余”的本质。在艺术创作上,作者采用横断面的描写,力求写出社会生活的真实面貌,因而《日出》具有纪实性特点,一切都像生活本身而不像“戏”。《日出》的思想是暴露半殖民地大都市黑暗糜烂面,控诉“损不足以奉有余”的社会。主题:一、剧本通过对半殖民地都市群丑的出色描绘暴露社会的黑暗糜烂揭露金钱社会对人的毒化吞噬与残杀。 二、描绘“不足”者的备受欺凌。剧本描写了许多弱小者的悲惨命运,也描写了他们善良、忠厚和倔强的品性。 把“鬼”似的人们生活的天堂与“可怜的动物”生活的地狱加以强烈对照,揭露出这个现代社会的畸形,不公正。作品“用多少人生的零碎来阐明一个观念”,并且使戏剧冲突尽可能地趋于自然贴近生活本身,暴露了整个社会制度的罪恶,并表现出对光明未来的某种理解和向往,在《日出》中,要证明一个根本观念:在金钱欲望无孔不入的腐蚀之下,社会几人的精神本质都产生了极大的差异,任何人的命运乃至整个社会的命运都被金钱疯狂操纵着,“人道”与“天道”完全背离。 ④《北京人》1941年出版的三幕剧,显示了曹禺的戏剧创作艺术在40年代打到新的高度,《北》以曾家的经济衰 落为串联全局矛盾冲突,并透过这些冲突,深入封建家庭这一躯体深处,着力反映出封建主义精神统治对人的吞噬,人们在这种精神统治下对人生的追求,以及这种精神统治的破产。人物语言简洁凝练,具有委婉深长的抒情诗意,剧本运用了独具蕴涵的象征意象和手法,以“北京人”命名,囊括史前社会现实社会理想社会三种“北京人”,象征剧本主题的丰富含义。全剧吸收了中国古典文学的营养又具有契诃夫戏剧的现实主义特色,“平淡的人生的铺述”是该剧的主要特征,它标志着曹禺戏剧的民族风格达到了新的美学境界,是由“戏剧化的戏剧”生命向“生活化(散文化)的戏剧”生命的转变。 ⑤《月牙儿》是老舍根据自己被毁于战火的长篇小说《大明湖》的主要情节改写的,小说展示了母女两代相继被 沦为暗娼的悲剧,发出了对非人世界的血泪控诉。小说结构精致玲珑,描写精致入微,贯穿全作的“月牙儿” 犹如一首乐曲的主旋律,是主人公命运的诗意象征,具有渲染气氛,烘托意境,组织素材,含蓄点题等多重作用,既加强了情节的韵律感,又使小说从头至尾洋溢着一种凄清哀婉的情愫,颇有散文诗之风,其艺术魅力震撼人心,历久不衰,《月牙儿》还显示出老舍表现人物心理活动的功力,是新文学的短篇小说中的精品。
