人教版新课标高中物理必修2功率教案2篇
1．用CAI课件模拟汽车的启动过程。师生共同讨论：①如果作用在物体上的力为恒力，且物体以匀速运动，则力对物体做功的功率保持不变。此情况下，任意一段时间内的平均功率与任一瞬时的瞬时功率都是相同的。②很多动力机器通常有一个额定功率，且通常使其在额定功率状态工作（如汽车），根据P=FV可知：当路面阻力较小时，牵引力也小，速度大，即汽车可以跑得快些；当路面阻力较大，或爬坡时，需要比较大的牵引力，速度必须小。这就是爬坡时汽车换低速挡的道理。③如果动力机器在实际功率小于额定功率的条件下工作，例如汽车刚刚起动后的一段时间内，速度逐渐增大过程中，牵引力仍可增大，即F和v可以同时增大，但是这一情况应以二者乘积等于额定功率为限度，即当实际功率大于额定功率以后，这种情况不可能实现。
人教版高中语文必修2《采薇》教案2篇
这两章是对战争场面的描写。写的是战车、战马、象弭、鱼服以及士兵的劳累奔波、饥渴难当，通过这些具体生动的细节描写来展现战争生活的图景。而没有写战场上的刀光剑影、厮打拼杀，但战争的残酷已可想见。4“昔我往矣，杨柳依依。今我来思，雨雪霏霏”被视为情景交融的佳句。清人王夫之在论《诗经·小雅·采薇》这两句时说：“以乐景写哀，以哀景写乐，一倍增其哀乐。”谈谈你的看法。一以往昔之虚衬眼前之实，以出征之乐衬内心之思亲之悲痛；二“杨柳依依”与“雨雪霏霏”对比，突出不胜今昔之感；三大雪交加，饥渴难当，情境实悲，以哀景写哀情。四、交流延伸1写一首诗或一段文字表达你对“乡愁”的新的体验。在全班交流。2课后搜集更多的表现乡情的诗歌散文作品，将你最感动的一篇拿到班上与同学分享感受。

人教版高中语文必修3《登高》教案2篇
【设计思想】诗歌教学的关键是感受诗景，体味诗情，领悟诗意，在此基础上孕育理解能力、鉴赏能力和审美情感。诗景、诗情、诗意均由文字来承载，把握文字组合的张力，是读诗赏诗的抓手。杜甫的诗歌素以炼字精深、涵盖深远著称，以《登高》而言，往往淡淡一字，平平一语，便笼大千于方寸，缩古今于一瞬。故细读文本，咀嚼字句，便是赏景、悟情、会意的基本路径。其次，不朽名作的特点是寄寓深广，古今评价甚多，见仁见智，不一而足。这正是培养学生问题意识、探究意识的极好凭借。第三，诗为语言之精华，是诗人心里涌出的情感之流。诵读乃赏诗之要着，精心感悟之时，设身处地，心惟口诵，是理解诗意的关键一步。基于是，笔者作如下同课异构，殊途同归。【教学目标】1．理解本诗所绘之景、所抒之情及绘景、抒情之法。2．学会用意象叠加法、字句推敲法、诵读体验法等欣赏诗歌。3．感受杜甫心系苍生、情寄邦国、忧国忧民、兼济天下的博大情怀。

人教版高中地理必修2人口合理容量教案
（1）请同学们结合日常生活实例和教材分析说明人类要在世界各地消除贫困并保持人口的合理容量任务的艰巨性？（2）采取何种措施才能更好的解决这一问题的出现？教师总结（1）现实中的人口问题（如人口过快增长、人口城市化和人口老龄化等）引发了严重的资源问题和环境问题。①发达国家的人均消耗资源量很大，索取资源和转嫁有害生产的地域超出了本国的范围。②发展中国家不仅人口数量多，人均消费水平低，而且一些国家的人口仍在快速增长。若在现有的经济基础上，把发展中国家人均生活质量提高到与发达国家相当的水平，所引发的资源短缺和环境问题将会相当严重，解决的难度也很大。（2）I就整个世界来说：①国际社会要倡导各国，尤其发展中国家要尽最大可能把人口控制在合理的规模之内；②建立公平的秩序，保证大多数人拥有不断追求高水平生活质量的平等权利。
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
【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。

巴金在十年浩劫中的大致经历：放弃包弟并没有换得保全一家人，1968年8月，巴金被关进牛棚改造，随后经受了大字报、挂牌游街等形式的批斗。1970年，到农村改造，掏大粪、喂猪、背稻草、种地……1972年，妻子萧珊在饱受精神折磨后患上癌症，病逝。巴金的儿子在劳动改造的过程中也饱受精神和肉体上的折磨，性格变得内向抑郁，疾病缠身。此时，巴金69岁。巴金曾在《病中》一文写道：“当姚文元拿着棒子的时候，我给关在牛棚里除了唯唯诺诺之外，敢于做过什么事情？十年间我不过是一条含着眼泪等人宰割的牛。”小结：（幻灯片12）社会是病态的社会，政治是高压的政治，人性是扭曲的人性。十年文革，十年浩劫，给多少人留下了累累不可弥合的精神创伤。即使一条小狗，也可能摆脱不了“文革”无情的迫害，比如包弟，比如艺术家邻居的小狗。
