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。
人教版高中语文必修4《柳永词两首》教案
（一）上片：描写杭州的自然风光和都市的繁华“东南形胜，三吴都会，钱塘自古繁华”，“东南形胜”，是从地理条件、自然条件着笔写的。杭州地处东南，地理位置很重要，风景很优美，故曰：“形胜”。“三吴都会”，是从社会条件着笔写的。它是三吴地区的重要都市，那里人众荟萃，财货聚集，故曰：“都会”。“钱塘自古繁华”，这一句是对前两句的总结，因为杭州具有这些特殊条件，所以“自古繁华”。下面就对“形胜”、“都会”和“自古繁华”进行铺叙。“烟柳画桥，风帘翠幕，参差十万人家”是对“三吴都会”的展开描写。“云树绕堤沙。怒涛卷霜雪，天堑无涯”是对“东南形胜”的展开描写。这里选择了钱塘江岸和江潮两种景物来写。“市列珠玑，户盈罗绮，竞豪奢”是对“钱塘自古繁华”的展开描写。描写了两个方面：一是商业贸易情况——“市列珠玑”，只用市场上的珍宝，代表了商业的丰富、商业的繁荣；二是衣着情况——“户盈罗绮”,家家披罗着锦。“竞豪奢”，又总括杭州的种种繁华景象。
