人教版高中语文必修2《短歌行》教案2篇
教学过程：一、导语毛泽东在《沁园春雪》俯视封建君王“惜秦皇汉武。。。只识弯弓射大雕。”但如果历史上只有一个人可以与他相提并论，这个人只能是魏武帝曹操。“滚滚长江东逝水，浪花淘尽英雄。是非成败转头空，青山依旧在，几度夕阳红。”（《三国演义》卷首词）在历史的大浪淘沙中，有多少英雄能够经得起历史的千淘万漉而流芳百世呢？曹操应该是三国时代留下了浓重一笔的人物。老师总结，并启发他们去联系:我们学过他的《观沧海》“东临碣石,以观沧海…”还有《龟虽寿》“神龟虽寿，猷有竟时。老骥伏枥，志在千里；烈士暮年，壮心不已。”《青梅煮洒论英雄》中曾和他见过，《三国演义》电视剧播出后，大家和他也就频频见面了。《三国演义》第48回“宴长江曹操赋诗”中，赤壁之战前夕，曹操和众部将一起狂饮，他四顾空阔，心中大喜，与诸将讲述自己希望收服江南的雄心壮志。
人教版高中语文必修3《劝学》教案2篇
五．研习第一段：1．诵读指导要处理好句中停顿2．请学生对照注释翻译本段重点词句：学不可以已已：停止。青，取之于蓝而青于蓝于：从；比。木直中绳中：zhàng符合，合于。虽有槁暴，不复挺者，揉使之然也有通又，揉通煣，以火烘木，使其弯曲。然：这样。翻译：故木受绳则直，金就砺则利，君子博学而日参省乎己，则知明而行无过矣。所以木材经墨线画过（再用斧锯加工）就直了，金属刀剑拿到磨刀石上（磨过）就锋利了，君子广博地学习并且每天对自己检验反省，就能智慧明达，行为没有过错了。3．本段是从哪个角度论述中心论点的？明确：本段是从学习的意义这个角度论述中心论点的。荀子认为人的知识、道德、才能都不是天生成的，而是后天不断学习获得的，学习的意义十分重大，所以学习不能停止。4．本段中几个比喻句是为了说明什么道理？学生讨论发言，教师明确：
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《廉颇蔺相如列传》教案
(2)个性化的对话描写。在三个事件的描述中，大段对话占了很大篇幅，有的情节干脆由对话来表达，许多对话形象地表现了人物的思想和性格，使我们如闻其声，如见其人。先说蔺相如，他在秦廷上的慷慨陈词，有时语气平和，谦恭有礼，使对方放松警惕；有时直言斥责，有理有据，雄辩折人；有时坚决表态，分析利害，暗示对方；有时怒不可遏，咄咄逼人。总之，词锋犀利，刚柔兼施，而又轻重恰当，充分表现了他是一个热爱祖国、不畏强暴、有智有勇，长于辞令的外交家。再说廉颇，在将相交欢事件中，他先前说的这一番话，表现了他的自高自大和心胸狭窄，非常符合武将廉颇的性格特点，后来写他知过改过，负荆请罪时说：“鄙贱之人，不知将军宽之至此也！”语言不多，坦诚直率，可敬可爱。（解说：对话描写的分析，宜以学生为主，教师必要时适当点拨。）
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
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5《咬文嚼字》教案
【教学过程】第一课时一、导入新课清代唐彪在《读书作文谱》中引用武叔卿的话说：“文章有一笔写成不加点缀而工者，此神到之文，尚矣。其次须精思细改，如文章草创已定，便从头至尾—一标点。”同学们能列举出文学史上的作家哪些属于前者，哪些属于后者吗？前者有李白。后者如贾岛、王安石、欧阳修、曹雪芹等。（贾岛有关于推敲的典故。王安石修改“春风又绿江南岸”句传为佳话。欧阳修《醉翁亭记》的开头便是精心改成的。《红楼梦》更是“披阅十载，增删五次。”）提问：古今的伟大作家为什么像李白式的诗人很少，而大多数人却都要“咬文嚼字”，苦苦修改呢？这节课我们就来研究一下这个问题。二、整体感知1．快速浏览全文，熟悉主要内容。2．根据“学习重点”，确立学习目标。三、课文分析1．理清观点与材料的关系。首先，让学生找出本文在论证中所运用的材料。
人教版高中历史必修2古代手工业的进步教案
①原因：封建制度的衰落（根本原因）【合作探究】清朝资本主义萌芽缓慢发展的原因。提示：①封建所有制的束缚。残酷的封建剥削使农民赤贫如洗，无力购买手工业品，限制了手工业产品的销路。封建地租的剥削率很高，又驱使地主和商人把他们的钱财用于购买土地，影响资本主义手工业的扩大再生产。②.封建政府的压制。清政府实行重农抑商的政策，采取了许多妨碍手工业生产和资本主义萌芽发展的措施，主要的有：实行闭关政策，严格限制海外贸易；在国内广设关卡，对商品征收重税；严格控制手工业的生产规模，如建立受官府控制的行会，制定行规限制雇工人数、产品品种、控制原料分配，限制产品销售的价格和地区范围等。②发展的表现：具有资本主义萌芽的部门和地区增多。（参见教材P10“学思之窗”）

（2）根据材料二与所学知识，从经济、政治、思想文化三个方面，分析欧洲近代科技迅速发展的原因。答：资本主义工商业的成长刺激了对技术的需求，为近代科技的发展提供了工具和手段；资产阶级革命为资本主义发展、科技进步开辟了道路；人文主义和理性精神解放了思想，推动近代科技迅速发展。（如答出其它原因，言之有理，可酌情加分，但不得超过该问总分）（3）根据材料二三与所学知识，分析清代（鸦片战争前）中国科技发展停滞的原因。答：君主专制维系腐朽制度；重农抑商、闭关政策阻碍资本主义萌芽发展；自然经济不能提供近代科技发展的物质基础；文化专制政策（或崇尚理学、八股取士、文字狱等）禁锢思想，摧残人才，阻碍科技发展。（如答出其它原因，言之有理，可酌情加分，但不得超过该问总分。）（4）简述从中西方科技发展变化的历史中得到的启示。答：评分说明：围绕生产力发展，政治经济变革、思想解放与科技发展的关系等任一角度回答，言之有理，均可酌情赋分
人教版高中历史必修3美术的辉煌教案2篇
画中的诸多图像反映了画家对于传统绘画因素的吸收。那个怀抱死去孩子的母亲图像，似乎是源自哀悼基督的圣母像传统；手持油灯的女人，使人联想起自由女神像的造型；那个高举双手仰天惊呼的形象，与戈雅画中爱国者就义的身姿不无相似之处；而那个张臂倒地的士兵形象，则似乎与意大利文艺复兴早期某些战争画中的形象，有着姻亲关系。由此可以看出，毕加索不仅是一位富于叛逆精神的大胆创新者，同时也是一位尊崇和精通传统的艺术家。教师须强调：现代主义美术是现代美术流派的总称，现代美术流派众多，多姿多彩，但它们也表现出许多共同的特征。在技法上，它们大都反对传统的写实主义，追求新奇，空间结构错乱，色彩配置随意，点线紊乱，缺乏透视可谓它们共有的特点。在创作主旨上，它们都主张强调自我，表现个人情感和内心世界。可以说，现代美术艺术再现了20世纪西方世界的精神状况。
