让学生仔细聆听美妙的音乐，合作讨论，加深理解。（1）本诗文中的“兰芝被遣”和“兰芝抗婚”的情节，可与乐曲展开部第一阶段“逼嫁抗婚”对比阅读。文中的刘兰芝是在封建礼教的压迫下被遣归及被迫“改嫁”，刘兰芝与祝英台一样都进行了抗争。乐曲中的乐器奏出了具有威胁力的封建势力的主题，代表着封建势力的凶暴残酷，同时叙述了祝英台的悲痛和不安心情，表现了控诉、抗争的感情。（2）本诗文中的“夫妻誓别”的情节，可与乐曲呈示部中的结束部“长亭惜别”对比阅读。文中刘兰芝与焦仲卿的誓别。二人分手之际，依依不舍，“举手长劳劳，二情同依依”。乐曲中梁祝分别时依依不舍又充满悲伤，音调抒情徐缓。让学生在徐缓的音乐中去感受刘兰芝与焦仲卿生离死别的痛苦。
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1摩擦力教案2篇
l．知识与技能：（1）知道摩擦力产生的条件。（2）能在简单问题中，根据物体的运动状态，判断静摩擦力的有无、大小和方向；知道存在着最大静摩擦力。（3）掌握动磨擦因数，会在具体问题中计算滑动磨擦力，掌握判定摩擦力方向的方法。（4）知道影响到摩擦因数的因素。2．过程与方法：通过观察演示实验，概括出摩擦力产生的条件及摩擦力的特点，培养学生的观察、概括能力。通过静摩擦力与滑动摩擦力的区别对比，培养学生分析综合能力。3．情感态度价值观：在分析物体所受摩擦力时，突出主要矛盾，忽略次要因素及无关因素，总结出摩擦力产生的条件和规律。二、重点、难点分析1．本节课的内容分滑动摩擦力和静摩擦力两部分。重点是摩擦力产生的条件、特性和规律，通过演示实验得出关系f=μN。2．难点是学生有初中的知识，往往误认为压力N的大小总是跟滑动物体所受的重力相等，因此必须指出只有当两物体的接触面垂直，物体在水平拉力作用下，沿水平面滑动时，压力N的大小才跟物体所受的重力相等。

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。
人教版高中历史必修1辛亥革命教案2篇
①从政府人员组成看，南京政府是一个以资产阶级革命派为主体的政府。②从政府颁发的法令和措施看，这些法令体现了资产阶级民主革命的要求，对于发展民族资本主义经济、资产阶级民主政治和文化教育以及改革社会风气，都起了积极作用。③从颁布的《中华民国临时约法》看，宪法体现了三权分立的政治体制，体现了资产阶级民主主义的要求，是中国历史上第一部资产阶级民主宪法，具有反封建专制制度的进步意义。（2）从南京临时政府的内外政策分析南京政府的根本弱点①未彻底地反封建。它没有采取比较彻底的反对封建主义的措施，特别是对封建统治的基础——地主阶级土地所有制没有触动，这样，南京临时政府也就不能真正地把广大人民群众动员起来，因而缺乏真正的群众基础。
人教版高中历史必修1鸦片战争教案2篇

人教版新课标高中物理必修1弹力教案2篇
一般情况下，凡是支持物对物体的支持力，都是支持物因发生形变而对物体产生弹力。所以支持力的方向总是垂直于支持面而指向被支持的物体。例1：放在水平桌面上的书书由于重力的作用而压迫桌面，使书和桌面同时发生微小形变，要恢复原状，对桌面产生垂直于桌面向下的弹力f1，这就是书对桌面的压力；桌面由于发生微小的形变，对书产生垂直于书面向上的弹力f2，这就是桌面对书的支持力。学生分析：静止地放在倾斜木板上的书，书对木板的压力和木板对书的支持力。并画出力的示意图。结论：压力、支持力都是弹力。压力的方向总是垂直于支持面而指向被压的物体，支持力的方向总是垂直于支持面而指向被支持的物体。引导学生分析静止时，悬绳对重物的拉力及方向。引导得出：悬挂物由于重力的作用而拉紧悬绳，使重物、悬绳同时发生微小的形变。重物由于发生微小的形变，对悬绳产生竖直向下的弹力f1，这是物对绳的拉力；悬绳由于发生微小形变，对物产生竖直向上的弹力f2，这就是绳对物体的拉力。
