  • 人教版高中语文必修2《离骚》教案2篇

    四、品味诗歌艺术1、诗人是如何表现其品质的?运用了什么修辞手法?产生了怎样的表达效果?明确:诗句“扈江离与辟芷兮,纫秋兰以为佩”很好地体现了诗人光辉俊洁的人格。用“江离”“辟芷”“秋兰”三种香草来装饰自己,比喻自己,极其生动形象地表现了诗人自己美好的精神世界,使诗歌充满了浪漫主义气息。2、《离骚》中作者常以“香草”、“美物”来比喻自己、贤士和君王,并表达政治理想,这是《离骚》的一大艺术特色,这种方法叫做“移情法”,即不直接说出自己想说的话,而是把它寄寓于某一物上,也就是“移情于物”,这种方法在古典诗词中广泛运用,在政治不清明的时代,借用“移情”,可言难言之语,抒难抒之情。请找出相关的诗句,说说诗人是怎样运用这些比喻来表达政治理想的。

  • 人教版高中语文必修2《囚绿记》教案2篇

    教学设想:本节课的主题是“生命之绿,璞玉心灵”,用圈点批注法解读爱绿的感情,让学生在批注中明确“绿”的象征意义,而不只是结论的传递。同时借助于阅读、感受和理解把握作者对绿的认识是不断升华的,由一般对生命希望之绿的喜爱,到与绿交往后被它的不畏强暴,永远向阳的精神所折服,最后在特定的时代背景下绿在作者的心目中已经成了我们民族不屈精神的象征。让学生评中求解,评中悟情,评中明理,评中品味。教学进程:一、导语上节课我们学习了朱自清的《绿》,初步了解了读书动笔的基本方法,这节课我们继续用圈点批注的方法来学习陆蠡的散文《囚绿记》。二、释题师:看标题,囚绿之“绿”在文中具体指什么?(一株常春藤)“囚”就是囚禁的意思,那题目就是记述囚禁绿色常春藤的经过。三、圈点、把握情节作者为什么要囚绿呢?文中除了写“囚绿”之外,还写了哪些有关绿的意念和行动?带着这样的质疑用自己喜欢的方式朗读课文,请同学们圈点出疑难字词,或结合书下注释,或同学合作解决,解决不了的,可提出来我们共同解决。标注段落节次。勾画出表现作者对绿意念和行动的句子。

  • 人教版高中语文必修3《蜀道难》教案2篇

    【明确】“一夫当关,万夫莫开”言剑阁有易守难攻的险要形势,暗示中央朝廷的部队很不容易打进来,因而野心家可以据险发动叛乱,“化为狼与豺”,搞地方割据。如果割据势力之间出现矛盾冲突,难免要发生混战,结果必定是“杀人如麻”。诗人这番预言在十多年后就得到了证实:从上元二年到大历初即有段子璋、徐知道、崔旰等人相继发动叛乱。诗人的意图是要严防野心家发难。诗人从剑阁的险要引出对政治形势的描写。他化用西晋张载《剑阁铭》中形胜之地,匪亲勿居的语句,目的在于劝人引以为鉴戒,警惕战乱的发生,并联系当时的社会背景,揭露了蜀中豺狼的磨牙吮血,杀人如麻,这既是描写蜀道猛兽,又是影射政治黑暗的双关语句,表达了对国事的忧虑与关切,为诗篇增加了现实的内涵、深厚的意蕴。唐天宝初年,太平景象背后正潜伏着危机,后来发生的安史之乱,证明诗人的忧虑是有现实意义的。

  • 人教版高中语文必修4《李贺小传》教案

    一、明确目标1.注意小传的写作特色,如小传的“小”以及是怎样小中见大的。2.引导学生进行综合把握和比较阅读以更好地理解课文内容,看看在写法上各自有什么不同。3.一词多义的准确知识运用二、整体感知1.解题李商隐的《李贺小传》有别于一般传记文的客观直叙,是一篇性情之文;同时也和作者的诗歌风格相异,写得朴实自然而又不乏意趣。2.本文所体现的“小传”的特点本文最大的特点在于:小传虽小,但小中有大、以小见大。其“小”在于:作者并没有全面勾勒诗人李贺的一生,对他的生平经历也记叙不多,而是选取了他生活中的若干小片段进行插叙,以小片段撑起传记的主干。此外,在篇幅上,全文寥寥数百字,语言极为精练。而其“大”又体现在:极小极短的篇幅却具有很大的容量,集叙事、议论和曲折的抒情于一体。内容浑厚,意味深长。

    【教学目标】1.熟读全文,掌握文中出现的重要的实词、虚词、古汉语句式;2.鉴赏本文融情于事的表达和形象精粹的语言;3.深入体会文章凄切婉转的陈情技巧。【教学重点】重要的古汉语语词知识【教学难点】理解作者当时的处境和李密祖孙间真挚深厚的感情【教学方法】作为教读课,选择串讲的方式,突出朗读,以期能做到既落实知识,又能体会文章之美。课时安排为两课时。要重点做好预习工作。【教学步骤】一、以苏轼的评论导入读《出师表》不下泪者,其人必不忠;读《陈情表》不下泪者,其人必不孝;读《祭十二郎文》不下泪者,其人必不友二、预习检测1、下列红色字注音完全正确的一项()A、臣以险衅(xìn)夙遭闵(mǐn)凶终鲜(xiǎn)兄弟常在床蓐(rù)B、猥(wěi)以微贱责臣逋(bǔ)慢犹蒙衿(jīn)育宠命优渥(wò)C、岂敢盘桓(huán)有所希冀(yì)日薄(bó)西山除臣洗(xiǎn)马D、逮(dǎi)奉圣朝过蒙拔擢(zhuó)门衰祚(zuò)薄更(gēng)相为命分析:B责臣逋(bū)慢,C有所希冀(jì),D逮(dài)奉圣朝。

  • 人教版高中语文必修5《孟浩然》教案

    【教学过程】导入:如果说唐诗是中国文学史中的一朵奇葩,那孟浩然则是点缀其上的一滴晶莹露珠,其充满魅力与特色的诗风在盛唐独树一帜,也为其在人才济济的诗史上刻下了永恒的印记。同学们能否先回忆一下,我们学过的孟浩然的诗歌有哪些?(《春晓》、《宿建德江》、《望洞庭湖赠张丞相》、《过故人庄》。)我们常说"中国古诗写胸襟,是人格美的自然流露",那么孟诗在语言和思想情感上留给你怎样的印象和感受?整体感知:本文作者闻一多先生也是一位诗人,所谓"英雄惜英雄",相同的志向与情趣使闻一多似乎带着我们在与孟浩然进行了一场心灵的对话。那么同学们在快速阅读文章之后,能否先找出作者是选择了一个怎样的角度对孟浩然评价的?(诗如其人,人如其诗。)

  • 人教版高中语文必修4《苏武传》教案

    二、课堂教学:1、学生简介背景:教师掌握:汉武帝开始对匈奴进行长期的讨伐战争,其中取得了三次具有决定意义的胜利,时间为公元前127年、前121年、前119年。匈奴的威势大大削弱之后,表示愿意与汉讲和,但双方矛盾还是根深蒂固。所以,到公元前100年,苏武出使匈奴时,却被扣留,并迫使他投降。《苏武传》集中叙写了苏武出使匈奴被扣留期间的事迹,热烈颂扬了他在敌人面前富贵不能淫,贫贱不能移,威武不能屈,饥寒压不倒,私情无所动的浩然正气,充分肯定了他坚毅忠贞,大义凛然,视死如归的民族气节。2、作者介绍:班固(32——92年),字孟坚,扶风安陵(今陕西咸阳市东)人。东汉著名的史学家。《后汉书·班固传》称他“年九岁,能属文,诵诗赋。及长,遂博贯载籍,九流百家之言,无不穷究。所学无常师,不为章句,举大义而已”。其父班彪曾续司马迁《史记》作《史记后传》,未成而故。

  • 人教版高中语文必修4《短文三篇》教案

    ③于是,大自然出现了惊人的奇迹,不毛的石缝间丛生出倔强的生命。④或者就只是一簇一簇无名的野草,春绿秋黄。岁岁枯荣。它们只有三两片长长的细瘦的薄叶,那细微的叶脉,告知你生存该是多么艰难;更有的。它们就在一簇一簇瘦叶下自己生长出根须,只为了少向母体吮吸一点乳汁,便自去寻找那不易被觉察到的石缝。这就是生命,如果这是一种本能,那么它正说明生命的本能是多么尊贵,生命有权自认为辉煌壮丽,生机竟是这样地不可扼制。⑤或者就是一团一团小小的山花,大多又都是那苦苦的蒲公英。它们不似田野上的同宗长得那样茁壮,它们的茎显得坚韧而苍老。它们的叶因枯萎而失却光泽。它们已经不能再去为人们作佐餐的鲜嫩的野菜,却默默地为攀登山路的人准备了一个可靠的抓手。生命就这样地被环境规定着,又被环境改变着,适者生存的规律尽管无情。但一切适者就是战胜环境的强者。生命现象告诉你,生命就是拼搏。

  • 人教版高中政治必修3体味文化教案2篇

    3、文化是人们的一种素养(1)人的文化素养是在社会生活、实践中形成的。每个人所具有的文化素养,不是天生的,而是通过对社会生活的体验,特别是通过参与文化生活、接受知识文化教育而逐步培养出来的。文化素养的形成,离不开生活、实践和教育。人们在社会实践中创造和发展文化,也在社会生活中获得和享用文化。(2)人的文化素养表现在日常言行中。教师活动:引导学生阅读教材7页“公交车漫画”材料,并思考所反映的问题学生活动:积极思考并讨论问题教师点评:人们的精神活动离不开物质活动,人们的文化素养总是要通过他在日常生活中的言行、在社会实践活动中的表现等表现出来。我们通过观察人们的社会行为,就可以从中透视人们的精神世界和精神生活。4、文化的传承和发展离不开物质载体。社会文化和精神产品离不开物质载体,一个时代的文化和精神产品,往往是这一时代社会发展轨迹的反映。
