人教A版高中数学必修一对数的运算教学设计（1）
本节课是新版教材人教A版普通高中课程标准实验教科书数学必修1第四章第4.3.2节《对数的运算》。其核心是弄清楚对数的定义，掌握对数的运算性质，理解它的关键就是通过实例使学生认识对数式与指数式的关系，分析得出对数的概念及对数式与指数式的 互化，通过实例推导对数的运算性质。由于它还与后续很多内容，比如对数函数及其性质,这也是高考必考内容之一，所以在本学科有着很重要的地位。解决重点的关键是抓住对数的概念、并让学生掌握对数式与指数式的互化；通过实例推导对数的运算性质，让学生准确地运用对数运算性质进行运算，学会运用换底公式。培养学生数学运算、数学抽象、逻辑推理和数学建模的核心素养。1、理解对数的概念，能进行指数式与对数式的互化；2、了解常用对数与自然对数的意义，理解对数恒等式并能运用于有关对数计算。

3、清代的“闭关锁国”政策：（1）原因：①根本原因：自给自足的封建自然经济；②客观原因：西方殖民者向东方殖民扩张；③直接原因：对付东南沿海人民的抗清斗争（2）内容：严格限制对外贸易。但并不是禁绝海外贸易。康熙晚期，禁止商人前往南洋贸易；乾隆时只开广州一处通商，并设立政府特许的贸易机构广州“十三行”统一经营管理对外贸易。（3）后果：①闭关锁国政策妨碍了海外市场的开拓，抑制了资本的原始积累，从而阻碍了资本主义萌芽的发展。②闭关锁国政策隔绝了中国与外界的联系，从而阻断了中国学习西方的先进科学技术，阻碍了生产力发展，使中国落后于世界潮流。③“闭关锁国”政策在一定程度上也保护了国家的安全。教师可以设置问题：17-18世纪中国显露出哪些危机？

师：分析得非常到位。大家来看看薛宝钗是怎么说的？薛宝钗的评论：“不像吟月了，月字底下放一个‘色’字倒还使得，你看句句倒是月色。这也罢了，原来诗从胡说来，再迟几天就好了。”生：（读第三首诗）“精华欲掩料应难，影自娟娟魄自寒。一片砧敲千里白，半轮鸡唱五更残。绿蓑江上秋闻笛，红袖楼头夜倚栏。博得嫦娥应借问，缘何不使永团圆！”这首诗语言很朴实，但意境很深远。我虽然读过《红楼梦》这本书，也看过电视剧，但我阅历太浅，说不出诗中所包含的深刻内涵。师：贾宝玉的评论：“这首不但好，而且新巧有意趣，可知俗语说的‘天下无难事，只怕有心人。2．意识的形式是主观的意识是人脑对客观存在的反映，意识是不是仅仅是人脑对客观存在原原本本的反映呢？“龙、凤”是中华民族的象征，是炎黄子孙的两大主要图腾，但地球上从来就没有出现过“龙、凤”，那么“龙、凤”的观念又是从何而来的呢？原来，“龙、凤”的观念最早产生于原始社会的图腾崇拜。、

高中国旗下讲话演讲稿
下面是由小编为大家整理的关于高中国旗下讲话演讲稿，欢迎阅读参考。希望可以帮助到你。“励”是鼓舞，劝勉;“志”是关于将来要有所作为的意愿和决心，是有识之士的心愿。“励志”是激发文气，以求有所作为的意思。励志，首先要有志向，有高尚、远大的理想和明确的奋斗目标。少年周恩来在全班同学面前表明了自己的心迹：要“为中华之崛起而读书”，而当时与他同班的其他同学读书的目的是为明理、为做官、为挣钱、为吃饭，只是为了满足个人修养和生活的需要，而周恩来不愿意自己的民族再软弱，不愿意自己的同胞受欺辱，他把个人的学习与民族振兴的大业联系起来，立下远大志向，为祖国的兴盛而学习和奋斗，后来成为新中国的第一任总理，受到全国人民乃至世界各国人民的爱戴。可见，高尚、远大的理想和明确的奋斗目标对人一生的引领作用有多么巨大!其次，励志一定要有实践，要为实现志向而进行不懈的努力。明朝的宋濂，他就是我们浦江人，家境贫寒但自幼好学，向别人借书来看;冬天砚台里的墨汁结成了冰，手指冻僵了他也从不停止;成年以后，他背着经书到很远的地方去寻师求教，天气严寒，路途险恶，脚上的皮肤冻裂了都不知道;到了老师那里，耐心等待，虚心请教;生活清苦，他一天只能吃上两顿饭，没有鲜美的鱼肉，穿着破衣烂袄，生活在一群衣着华丽的纨绔子弟中间，却乐在其中，一点也不羡慕别人。
