人教版新课标高中物理必修2太阳与行星间的引力教案2篇
【学习内容分析】在行星运动规律与万有引力定律两节内容之间安排本节内容，是为了更突出发现万有引力定律的这个科学过程。如果说上一节内容是从运动学角度描述行星运动的话，那么，本节内容是从动力学角度来研究行星运动的，研究过程是依据已有规律进行的演绎推理过程。教科书在尊重历史事实的前提下，通过一些逻辑思维的铺垫，让学生以自己现有的知识基础身于历史的背景下，经历一次“发现”万有引力的过程，因此体验物理学研究问题的方法就成为主要的教学目标。【学情分析】在学太阳对行星的引力之前，学生已经对力、重力、向心力、加速度、重力加速度、向心加速度等概念有了较好的理解，并且掌握自由落体运动和圆周运动等运动规律，能熟练运用牛顿运动定律解决动力学问题。已经完全具备深入探究和学习万有引力定律的起点能力。所以在推导太阳与行星运动规律时，教师可以要求学生自主地运用原有的知识进行推导，并要求说明每一步推理的理论依据是什么，教师仅在难点问题上做适当的点拨。

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1《小狗包弟》教案2篇
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。
人教版高中语文必修1《再别康桥》教案2篇
教学过程：一、交流诵读课文技巧。——节奏、韵脚、感情……（5分钟）二、再读确定自己的学习主题（15分）1、主题提示：音乐美、绘画美、建筑美简介诗歌“三美”追求闻一多先生是我国现代文学史上集诗人、学者和斗士于一身的重要诗人。他不但致力于新诗艺术美的探索，提出了音乐美、绘画美、建筑美的诗歌\"三美\"的新格律诗理论主张，还努力进行创作实践，写出了许多精美诗篇。他的新格律诗理论被后人称为现代诗学的奠基石，影响深远。《诗的格律》是闻一多先生系列诗论中最重要的一篇。在这篇论文中，他系统的提出\"诗的实力不独包括音乐的美（音节）、绘画的美（词藻），并且还有建筑的美（节的匀称和句的均齐）。\"这一关于新诗\"三美\"主张遂成为新格律诗派的理论纲领。
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《马嵬（其二）》教案2篇
结合历史自古以来，江山美人历来都是引无数英雄豪杰竞折腰的，如果说英雄选择了美人却丢了江山，把所有罪名都归结于“女人是祸水”。但是，纣王无道，和有了妲己有必然的联系吗？有人说妲己坏透了，坏透了的妲己如果不是取得纣王的信任是坏不起来的，纣王听信了妲己的谗言，听与不听决定权在纣王，而不在妲己。强势永远在纣王一边。再来看看西施和杨贵妃：西施是作为越国贡献给吴国的供品来到吴王夫差的身边的，杨贵妃更是先是李隆基的儿媳妇被看中而得宠的。所以，西施和杨贵妃这两个可怜的女人根本没有自己的独立选择，没有独立的爱情，如果没有西施，就会有南施，或北施；如果没有杨贵妃，就会有李贵妃，王贵妃，总之什么施，什么妃是不能少的，因为那是吴王和李隆基的需要。
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。
人教版高中历史必修2开辟新航路教案
材料五航路开辟后，东方香料输入欧洲的总量较中古之时猛增30倍，而胡椒、丁香等在印度购入和在英国卖出的差价亦高达10至29倍，其他货物的获利同样惊人。这一时期，新的商品不断涌现，特别值得注意的是美洲的特产——玉米、马铃薯、烟草、可可等——被传播到欧亚大陆。这时，世界性的对外贸易主要通过大西洋，地中海与意大利皆告衰落，而沿大洋的英、荷等渐居中心。到17世纪时，英国的伦敦与荷兰的阿姆斯特丹成为世界贸易中心。问题4：材料五表明，新航路开辟后对世界贸易产生了哪些重大影响？答案4：结束了世界相对孤立状态；各地文明开始会合交流，日益连成一个整体；欧洲商人直接同世界各地建立商业联系；促进不同国家和贸易的发展，促进世界市场雏形开始出现。

人教版高中政治必修3体味文化教案2篇
3、文化是人们的一种素养（1）人的文化素养是在社会生活、实践中形成的。每个人所具有的文化素养，不是天生的，而是通过对社会生活的体验，特别是通过参与文化生活、接受知识文化教育而逐步培养出来的。文化素养的形成，离不开生活、实践和教育。人们在社会实践中创造和发展文化，也在社会生活中获得和享用文化。（2）人的文化素养表现在日常言行中。教师活动：引导学生阅读教材7页“公交车漫画”材料，并思考所反映的问题学生活动：积极思考并讨论问题教师点评：人们的精神活动离不开物质活动，人们的文化素养总是要通过他在日常生活中的言行、在社会实践活动中的表现等表现出来。我们通过观察人们的社会行为，就可以从中透视人们的精神世界和精神生活。4、文化的传承和发展离不开物质载体。社会文化和精神产品离不开物质载体，一个时代的文化和精神产品，往往是这一时代社会发展轨迹的反映。
