人音版小学音乐一年级下火车开啦说课稿
6、你言我语尽情唱游开火车的唱游对于学生来说是没有什么难度的，我不想手把手的教，而是想让孩子自己摸索出开好火车的方法，于是我说“想把火车开好可不是一件容易的事情，因为火车有好多车厢连在一起，怎么把它连起来？怎么开，我们一起来商量一下。学生有很多方法有的建议拉着前面同学的衣服、搭着前面同学肩膀，我让学生跟我一起来演示，一起研究，大家一起决定什么动作比较好。最后，师生都认同右手搭在前面同学肩膀，左手做车轮滚动的样子。就这样，一列列小火车很快就能够上路了。在唱游过程中，学生不可避免的是相互碰撞，这时停下音乐，宣布：“现在发生了交通意外，请各辆小火车赶快回到自己的位置。”一起讨论怎样才能安全行驶，相互不让路，不喧哗。7、开动火车乐趣无限唱游结束后，我安排了一个游戏：音乐中，两列小火车在教室里自由行驶，音乐停下时到站请旅客上车，音乐开始后继续旅行，直到所有的乘客都上车。这个游戏的设计也是为了让学生体会共同游戏的乐趣，在游戏中学会礼让，安全驾驶。

人音版小学音乐六年级下册火车来了说课稿
1、视觉图象法：少数民族的风土人情对我们汉族的孩子来说不那么了解。为了使他们更直接地了解到新疆柯尔克孜族人们的生活习惯，我运用电脑软件制作了一些柯尔克孜族的风情画面，给学生视听结合，避免枯燥的说教形式，使本来抽象的 内容变得具体形象化。2、对比欣赏法：在了解这个民族的风土人情时，我运用画面表格形式将新疆几个民族的人物作对比，从而使学生更清楚的了解这个民族的风土人情、歌曲特点。在教学中我还运用了创设情景、兴趣引入法、感性到理性等方法 。音乐家修海林认为“音乐审美必须要求体验到音乐的意境”，在这一课，我充分运用了多媒体教学手段，尽量让学生体验到音乐的意境，从屏幕上看到新疆的风土人情关系，听到新疆民歌不同的风格特点。

月球对地球的意义月球与地球形影相随，关系密切。月球对地球的影响，主要有以下几方面：1．地球上夜晚的自然照明，主要靠月亮。2．远在古代，人们就根据月相变化的周期，编订历法。我国农历月份的安排，是以月相变化 周期为标准的。农历规定朔为初一，这样，望就在十五日或十六日。我国人民的传统节日，像春节、中秋节就是按农历的月日计算安排的。3．由于地球表面各处所受月球和太阳引力的不同，地球上的水体产生了明显的潮汐现象。4．月球是人类星际航行的第一站。已知月球表面有多种宝贵矿藏；重力较小；没有大气层，利用太阳能的条件较好。如何利用月球的特殊环境，开发月球的资源，以及如 何利用月球作“码头”，使人类更好地研究宇宙，这将是月地关系的新篇章。

After graduation, he realized that what farmers needed most was to boost yields in the fields. Yuan was convinced that the answer lay in the creation of hybrid rice, one characteristic of which is that it usually achieve higher output than conventional crops. However, it was no easy job. The first difficulty he needed to overcome was scientists’ general assumption that this could not be done. Through trial and error, Yuan managed to generate this incredible crop. It is estimated that about 60 percent of domestic rice consumption in China was comprised of crops generated from Yuan’s hybrid strains.

人教版高中地理选修2百万移民及其安置教案
三峡库区农村移民安置根本出路是通过发展大农业来解决耕地不足，不应盲目开垦荒坡地，防止产生新的水土流失，尽量避免生态环境恶化。2、就地后靠，就近安置模式三峡库区淹没区线状分布的受淹特点有别于一般水库淹没区的片状分布，使得库区移民具有相对分散的特点，且淹没涉及的356个乡镇没有一个被全淹，甚至全淹的村也很少，这有利于移民在本县甚至本乡就近后靠安置，避免了水库移民大量外迁、远迁所造成的种种困难和后遗症。三峡移民搬迁大多可以就地后靠，就近安置，这是三峡移民的一大特色。就近后靠安置的优点是不离本乡本土，移民容易接受，且避免了移民大量外迁、远迁所造成的困难和后遗症；缺点是容易对当地的生态环境造成过大的压力，如过度开垦坡地、破坏植被、加剧水土流失等。3、工程周期长，可从容安置移民三峡工程建设周期长（1994年～2009年，共17年），使得移民安置能够及早进行，可以从容安置移民的生产和生活。
