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。
人教版新课标高中物理必修2平抛运动教案2篇
（五）平抛运动规律的应用例1：一架老式飞机在高出海面45m的高处，以80m/s的速度水平飞行，为了使飞机上投下的炸弹落在停在海面上的敌船，应该在与轰炸目标的水平距离为多远的地方投弹?不计空气阻力。分析：对于这道题我们可以从以下几个方面来考虑：(1)从水平飞行的飞机上投下的炸弹，做什么运动?为什么?(2)炸弹的这种运动可分解为哪两个什么样的分运动?3)要想使炸弹投到指定的目标处，你认为炸弹落地前在水平方向通过的距离与投弹时飞机离目标的水平距离之间有什么关系?拓展：1、式飞机在高出海面45m的高处，以80m/s的速度水平飞行，尾追一艘以15m/s逃逸的敌船，为了使飞机上投下的炸弹正好击中敌船，应该在与轰炸目标的水平距离为多远的地方投弹?不计空气阻力。2、在一次摩托车跨越壕沟的表演中，摩托车从壕沟的一侧以速度v＝40m/s沿水平方向向另一侧，壕沟两侧的高度及宽度如图所示，摩托车可看做质点，不计空气阻力。（1）判断摩托车能否跨越壕沟？请计算说明（2）若能跨过，求落地速度？

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。

一、低湿地的治理与开发1、 低湿地治理开发的原因——辛店洼自然条件的主要特点（1）地势低平：辛店洼洼底海拔17．5米，洼缘海拔19．5米，是全市最低点。（2）渍涝严重：其成因如表6-4所示（3）土质好、水源足、水质好：成土母质为黄河冲积物，土壤质地好；水资源丰富，水质较好。2、低洼地治理开发的方法：鱼塘——台田模式（或称塘田模式）以往辛店洼曾采用挖沟排水的措施治理低洼地，但治理效果不明显，因为辛店洼的主要矛盾是地势低洼，地下水位高，挖沟排水因地势低，排水困难，地下水位难以下降，故治理效果不明显。20世纪80年代以来，科学工作者在辛店洼地区开始了整治低湿地的研究，他们遵循“因洼制宜”的指导思想，逐步摸索出了低湿地的治理模式：鱼塘—--台田模式

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。

人教版高中政治选修3美国的三权分立教案
国会一直在政治生活中居于主导地位；到了当代，则是总统居于主导地位。由于司法机关无权直接支配社会力量和财富，相比之下，联邦法院力量向来较弱。第二次世界大战后，由于美国一直追逐全球霸权，美国总统的战争权力更加强化，向海外派遣军队的次数更加频繁。美国人民日益觉察到这种不断增长的“帝王般总统职位”可能带来的危险。2、三权分立制的本质——是一种资产阶级民主制度美国的三权分立制本质上是一种资产阶级民主制度。二百多年的历史经验表明，它有效地维护了美国资产阶级的统治。但是，广大劳动人民不可能在这种制度下享有真正的民主。虽然三大权力机关之间互相制约、平衡，却没有一个代表人民意志的权力机关，因而不可能实现人民群众的多数人统治。◇本框题小结：◇3个3种权力：3种权力即立法权、行政权和司法权；3个弊端：即三权分立原则的3 个弊端；3个中央政权机构即立法机关、行政机关和司法机关；◇2个原因：即确立三权分立原则的原因◇1个本质：即三权分立原则的本质

人教版高中政治必修2我国的宗教政策教案
（1）宗教有它自身的发展规律，不能简单的用行政力量去消灭或发展宗教，实行宗教信仰自由政策是遵循宗教发展规律，科学处理宗教问题。（2）宗教信仰自由是宪法赋予公民的民主权利，实行宗教信仰自由政策有利于加强信教群众与不信教群众的团结，引导宗教与社会主义社会相适应。2、弘扬科学精神我国是在马列主义、毛泽东思想、邓小平理论、三个代表重要思想指引下的社会主义国家，要建设社会主义物质文明、政治文明，也要建设社会主义精神文明。加强对人民群众的科学世界观和无神论教育，形成文明、健康、崇尚科学的社会风尚，逐步消除宗教存在的社会根源何认识根源，在保护宗教信仰自由的同时，创造宗教消亡的条件，这是解决在教问题的根本途径。3、中学生作为中国特色社会主义事业未来的建设者，要用辩证唯物主义和历史主义以及现代科学文化知识武装自己，弘扬科学精神，树立科学世界观，承担起建设祖国、振兴中华的光荣历史使命。
