    人教版高中语文必修2《荷塘月色》教案3篇

    请问,作者究竟听到歌声没有?”学生回答:“没有。”“这里是比喻,因为这里用得是‘仿佛’一词……”对,是比喻。也就是说,作者是用歌声来比喻荷香,是吧?“但是,“荷香与歌声有什么可比的共同点吗?”“荷香与歌声都是断断续续、若有若无的。”“而且朦朦胧胧的。”“对。“荷香和歌声都是‘缕缕’的、‘渺茫’的。这是比喻。这是一种特殊的比喻,钱钟书先生把它叫做‘通感’。人们通过视觉、听觉、触觉、味觉、嗅觉等五官感知外界事物时,在一般情况下,彼此不能交错;但在特殊情况下,五官功能却能出现互相转化、彼此沟通的现象叫“通感”,也叫“移觉”。举几个例子来说明:诗人艾青曾写诗这样描绘日本著名指挥家小泽征尔:‘你的耳朵在侦察,你的眼睛在倾听……’这也是通感。又如:“那笛声里有故乡绿色平原上青草的香味,有四月的龙眼花的香味,有太阳的光明。”(郭风《叶笛》)

    人教版高中语文必修3《琵琶行 并序》教案

    9、在乐曲终了之后,诗人以“东船西舫悄无言,唯见江心秋月白”两句结尾,这两句作用如何?明确:诗人没有直接写听者的热烈反响以说明琵琶女技艺非凡和乐声的感人至深,否则过于直白就不含蓄,不含蓄也就显不出深沉了。用“东船西舫悄无言”的寂静无声,反衬“有声”的音乐效果,可谓“此时无声胜有声”了。人们无声地沉浸、陶醉在艺术的享受之中,那深深打动人的乐声仿佛缭绕迂回耳际,不由得使诗人想到了自己浩茫的心事,引起情绪上的波澜。在这片刻的沉寂中,只见一轮迷蒙的冷月荡漾在江心的微波之中,它提醒诗人从乐声中回到现实中来。这句景物描写点染烘托了浓重的氛围,与复杂的乐声融为一体,共同表现了琵琶女与诗人息息相通的复杂情感,是那么的忧愤、哀怨凄楚、苍凉,给整个音乐形象补足了画龙点睛之笔。

    人教版高中语文必修3《老人与海》教案2篇

    (一)导入[以视频欣赏导入]同学们,刚才欣赏的是大家熟悉、喜欢的电视剧《亮剑》中的精彩片段——李云龙论述什么是“亮剑”精神?同学们听后觉得好不好?牛不牛?“亮剑”精神简单理解就是敢于与强大的敌人(对手)做斗争,无论对手多么强大,都要满腔勇气和信心,永不放弃、永不言败,要敢于亮剑……今天我们一起来学习世界100部著名文学作品之一、美国里程碑式30部文学作品之一的世界名著——海明威的《老人与海》,看看主人公桑提亚哥“硬汉”性格和李云龙“亮剑”精神有么相似的地方。(请同学们翻到课文,课件显示课题《老人与海》)(二)走进作者:请同学们自己谈收集到的有关海明威的资料,然后教师梳理出下列核心内容识记:(课件显示)海明威(1899~1961),美国现代作家,20世纪美国文学史上最耀眼的名字之一。早期作品表现了第一次世界大战青年一代的彷徨情绪,以“迷惘的一代”的代表著称。20世纪末回到美国,写了不小以拳击家、渔民、猎人等为主人公的短篇小说,创造了“硬汉子”性格。

  • 人教版高中语文必修3《蜀道难》教案2篇

    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3《祝福》教案2篇

    人教版高中语文必修3《祝福》教案2篇

    小结人们对待祥林嫂这个“嫁而再寡”的不幸女人态度:①、鲁四老爷的态度:不让她干祭祀的活(71、73、75、108通过四婶先后三喊“你放着罢”,杀人不见血地葬送了祥林嫂的性命。而其中尤以最后一次对其打击最大)。鲁四老爷站在顽固维护封建宗法制度的立场上,从精神上残酷地虐杀她。他暗暗地告诫四婶的那段话,就是置祥林嫂于死地而又不露一丝血痕的软刀子。②、鲁四婶的态度:鲁四婶是“大户人家的太太”,头一次留祥林嫂是看她能干,祥林嫂被婆家绑架走以后,她害怕给自己家惹麻烦。之后她惦念祥林嫂不是因为关心她的命运,而是自己的佣人都没有祥林嫂那样可心。以后祥林嫂再来,她“起初还踌蹰”,后来倒是真心怜悯祥林嫂,留下她。但是祥林嫂不像过去那样灵活能干了,四婶开始“不满”,进而“警告”,最后把祥林嫂赶出家门。可以说,四婶只是把祥林嫂当成一件工具罢了,没有把她当人来看。

  • 人教版高中语文必修4《李贺小传》教案

    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。

  • 人教版高中语文必修4《张衡传》教案

    人教版高中语文必修4《张衡传》教案

    采用明段意分段法:先逐段概括段意,然后用合并同类项法把相关联紧缩密的自然段合在一起。全文五个自然段中,二、三、四自然段讲的都是张衡取得的科学成就,自然应合为一大段。这样,就理清了文章的结构。全文可分为三个部分:(1)写张衡的品格和文才①(2)写张衡在科学技术上取得的成就(②③④)(3)写张衡的政治才干(⑤)第二部分是文章的重点,又可分为两层:一是仕途情况,以及制作浑天仪和著《灵宪》、《算图论》的情况;一是专门介绍候风地支仪。显然,后者又是第二部分的重点。作者这样处理文章的详略安排。无疑是非常正确的,因为张衡一生有多方面的才能和成就,而他在科技方面的才能和创造发明最为突出,理应成为本文记叙的重点。四、小结1.了解全文的内容和结构,掌握明段意分段法。2.了解文章的详略安排。五、作业

  • 人教版高中语文必修5《孟浩然》教案

    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5《逍遥游》教案

    人教版高中语文必修5《逍遥游》教案

    六、到此为止,我们了解到,作者对“笑”鲲鹏和别人的蜩与学鸠、斥鴳、宋荣子都一一作了否定。那么请大家讨论一下,1、作者对鲲鹏和“知效一官,行比一乡,德合一君,而征一国者”是不是肯定呢?明确:也都作了否定。否定后者好理解,关键是否定前者不好理解,因为“鲲鹏展翅”早已作为积极的意象被人们广泛引用。但在本文中,作者在讲述这一寓言故事时,突出的不是鲲鹏本身,而是风力,“故九万里,风斯在下矣,而后乃今培风;背负青天,而莫之夭阏者,而后乃今将图南”。对风力作用的突出,实际上就是对鲲鹏的否定。作者写了“笑”的双方,对“笑”的一方蜩与学鸠、斥鴳、宋荣子都作了否定,对被“笑”的一方鲲鹏和“知效一官,行比一乡,德合一君,而征一国者”也都作了否定,并且对顺便提及的野马、尘埃、芥、大舟、朝菌、蟪蛄、冥灵、大椿、彭祖、列子等事物或者人物也都作了否定。这种全盘否定的态度,如果我们借用本文中的一个形象的词语,可以说是:笑!是的,本文也可以说是:庄子“笑”万物!

  • 人教版高中语文必修4《苏武传》教案

    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《李清照词两首》教案

    2.【提问】《醉花阴》反映的是早年丈夫赵明诚游宦在外,作者一个人留在家中的生活状况和内心感受。对于这样的“闺怨”题材,应当怎样评价呢?【明确】作者作为一个封建时代的妇女,能够坦率地表达出自己对于丈夫深深的思恋之情,描写了闺中生活的孤独寂寞,这在当时乃是一种很大胆的行为。所以,有人批评说:李清照作词是“无顾忌”地“肆意落笔”。其实,感情的充沛、真挚,敢于正面地展露自己的行为和内心世界,正是她创作成功的重要原因之一,也正是她的词最值得珍视的地方。3.【提问】古人常常爱用花比喻人之美貌,如“芙蓉如面柳如眉”,“人面桃花相映红”等,而李清照却说“人比黄花瘦”,这样的比喻有什么丰富的内涵?【明确】黄色的菊花不止外形上雅淡、清秀,与作者因相思而消瘦的体态相近,而且在菊花品格的传统象征意义上,也酷似作者清高、淡泊的精神,这样的比喻正比较恰切地反映了当时作者由于离开丈夫而孤独、愁闷的生活状态和内心情感。
