大班游戏教案：拼音识字教学游戏大全
操作过程：（1）做这个游戏可以根据不同的内容采用不同的形式。开火车可以横着开，也可以竖着开，还可以开双轨列车。（2）导语：小朋友，我们一起来开小火车，看哪一列火车最先开到我们首都北京。开火车时，其他孩子学着很轻很轻地发火车开动的“呜——咔嚓、咔嚓” 的声音，有利于营造气氛，激发学生的学习兴趣。（3）例，教师在复习学过的生字时，可以用卡片先出示一个生字，然后让一组学生轮着读生字字音、组词师：“请第一组开双轨列车，先读读字音，再给它找个朋友。” 谁说错了，火车就停下。师：“哪个修理员来帮着修理一下？” 选其他组的修理员修理（重读字音、字母），修理好了继续开。第二种游戏名称：找朋友适用范围：复习字的偏旁、结构，正反义词，以及声母与韵母的相拼。 游戏准备：有生字的金牌，花形卡片 操作过程：（1）导语：小朋友，你想找到你的好朋友吗？让我们来做一个找朋友的游戏。（2）如，第一册《识字4》，在学了生字后，请学生找相同偏旁的字做你的好朋友，就可以这样操作。一生拿一张卡片“打”，说：“找呀找，找呀找，谁是我的好朋友？” 拿卡片“拔”和“拍”的同学就都可以上前说：“我是你的好朋友。” 大家说：“对对对，‘拔’是‘打’的好朋友。”最后大家一起读读两位好朋友手中的字，说说这两个字的偏旁。又如，教师可以做几个金牌，金牌上贴有生字“跑”“跳”，大家一起拍手说：“找呀找，找呀找，找到一个好朋友。” 挂金牌的同学看一看读一读生字，与挂有相同偏旁字的小朋友手拉手，成为好朋友。找对了，大家说：“对对对，你们是一对好朋友。” 找错了，大家说：“错错错，赶快再去找一找。” （3）教师也可以准备一些声母或韵母相同的生字，用金牌的形式挂在大家胸口，先读一读，然后让小朋友选择字音中相同部分的字手拉手，交朋友。还可以教师准备字型结构相同的或能组成词语的两个生字，准备一些声母和韵母，让学生读后手拉手交朋友。（4）这样在游戏中能激发学生的学习兴趣，在游戏中巩固所学知识。

全班齐读第五段内容。请一位同学分析，接着让这位同学按他分析的读一遍。3、4两自然段的平缓之后，第5段作者的情感再次抬升。为了满足这种情感的张扬，作一口气连用了四个排比句式“现在是……时候”，一方面这是情感发泄的需要，另一方面这种排山倒海的语势也加强了内容的表达，极强地突出了现实为自由、平等而战的重要性。四、学会演讲我们刚才细读了课文，但读和讲是有区别的。所谓演讲，是一门语言艺术，它的主要形式是“讲”，即运用有声语言并追求言辞的表现力和声音的感染力；同时还要辅之以“演”，即运用面部表情、手势动作、身体姿态乃至一切可以理解的态势语言，使讲话“艺术化”起来，从而产生一种非凡的艺术魅力。那么，接下来就假设一下假如你是马丁·路德·金，你会怎样去讲这篇演讲辞。
人教版高中语文《我有一个梦想》教案
一、导入新课年纪稍大的中国人应还记得，1968年春，"文革"还正如火如荼之际，毛泽东发表了一篇"五二Ｏ声明"，全国各地为此举行了由上级组织的大规模游行。很多人应还记得，事情同马丁·路德·金被刺杀有关，而这位马丁·路德·金，乃是著名的美国黑人民权运动领袖。事过多年之后，我却发现，不少人居然把这位诺贝尔和平奖得主，同四百多年前那位德国宗教改革领袖马丁·路德相混淆，而对他的主要主张"非暴力抵抗"，更是懵然无知！1956年，在26岁的马丁·路德·金第一次领导黑人市民，抵制蒙哥马利市公共汽车公司的种族隔离制度时，他就举起了"非暴力抵抗"的旗帜。他号召久被歧视的黑人群众说："我们要抵抗，因为自由从来不靠恩赐获得。有权有势的欺压者从不会自动把自由奉献给受压者。……权利和机会，必须通过一些人的牺牲和受难才能得到。"但是，"仇恨产生仇恨，暴力产生暴力……我们要用爱的力量，去对付恨的势力。我们的目标，绝不是击败或羞辱白人，正相反，我们要赢得他们的友谊和理解。"
