小班主题活动春天来了课件教案
主题思路春天是万物复苏的季节，在幼儿的周围，大自然中，处处都表现出生机勃勃，变化万千：红红的花、绿绿的草，枝头的嫩芽、飞舞的蝴蝶和刚刚出壳的小鸡、小鸭以及暖暖的阳光，柔柔的春风，到处充满春天特有的景象。幼儿置身在春天的自然景物之中，真切地感知春天来了，春天多么美！在本主题中，教师应努力创造条件，鼓励幼儿运用自己的感官通过看、摸、闻、听等多种途径与春天互动，让幼儿能初步感受大自然的神奇、逐步地亲近和喜爱大自然，并学习用多种途径表达、表现出自己对春天的情绪、情感、感知和体验。春天来了（语言） 嫩芽 （语言） 两片树叶（语言） 美丽的花蝴蝶（科学）感知积累 洗澡（语言） 认识金鱼（科学）种植洋花萝卜（科学） 小鸡和小鸭（科学） 花儿好看我不摘（社会） 发展线索 去春游（社会）春天（音乐） 春风（语言） 表现表达蜜蜂做工（音乐） 小小蛋儿把门开（音乐） 小金鱼（音乐）。 开满鲜花的草地（综合）环境设置
部编版语文八年级下册《阿西莫夫短文两篇》教案
第一部分（第1~4段），提出关于6500万年前恐龙灭绝的问题，目前存在的两种对立的理论，即“撞击说”和“火山说”。第2和第3自然段先后举了两个例子提出了关于“撞击说”和“火山说”这两种观点。第二部分（第5段至全文完），通过对“被压扁的沙子”的反思，证明外星撞击导致恐龙灭绝，支持“撞击说”。这部分又分四层。第一层（第5、6段），说明关于恐龙灭绝的原因不仅仅是一个学术问题，我们以后也许还会遇到这种情况，因此，科学家们一直都在努力寻找证据来验证这两种理论。第二层（第7~10段），说明1961年一位苏联科学家发现了“斯石英”，并且介绍了它的性质，为下文佐证“撞击说”奠定了基础。第三层（第11~13段），说明斯石英不仅可以在实验室制造，而且它在自然界中是可以存在的，不过它们只出现在沙子被强烈挤压的地方。由此推断撞击是可以产生斯石英的。事实也证明，火山喷发是不会产生斯石英的，从而进一步佐证了“撞击说”。

预设 示例1：“板块背上驮着许多大陆，当板块向一个或另一个方向运动时，大陆也随之一起运动。”“驮”字形象地写出了大陆漂移的样子，使抽象的理论变得生动、有趣、易懂。示例2：“位于南极中心部位的南极洲是全球的大冰箱。”运用了打比方的说明方法，形象地说明了南极洲寒冷的程度和南极洲在地球生态环境中的重要位置。 示例3：“一立方英寸被压扁的沙子比一立方英寸普通的沙子要重得多。”运用作比较的说明方法，说明同体积被压扁的沙子比普通沙子重得多的特点。【设计意图】本环节设计的三个层次的语言赏析，让学生深入文本体会、学习语言简明精练、逻辑性强、幽默风趣的特点，提高学生的语言鉴赏能力，为今后的说明文写作夯实基础。四、总结拓展，激发思维所选的两篇课文就同一对象——恐龙从不同角度思考，从而发现新的论据或得出新的结论。文章给了我们一些有益的启示：不同领域的科学发现可以互相启发，从而有新的发现；要学会从不同角度思考问题。选择下面两个探讨任务之一课外完成。

预设 示例：班上分享个人读书经验大家好！既然今天是交流读书体会，那么，我想结合自己的读书体会和大家聊聊读书。一个爱读书的民族，必定是一个文化素质较高的民族;一个爱读书的人，也必定是一个文化素质较高的人。读书能开阔我们的视野，提高我们的写作水平；读书能提升自身修养，丰富我们的人生底蕴。读书是我们精神的呼吸，能让人保持平淡的心境，变得博爱而无私。为了让我们的生活和心灵变得轻盈一些，我们需要读书。那么，应该怎样读书呢?其一，要择书而读。需要的才是最适合的，读适合的书才能有良多收获。如果没有特别需要的书要读，可以读经典。经典是经过岁月沉淀下来的人类智慧的结晶，可以让我们触摸先贤的思想，以充实自身。其二，要读而有术。要对好书反复品味，将其内化吸收，然后进行批判性阅读，有自己的思想主张和拓展探究价值判断;在读书过程中与作者进行辩论，最后形成自己的思想体系，为我所用，而不是让自己的脑袋成为别人思想的“跑马场”。

八荣八耻的国旗下讲话稿[社会主义荣辱观]
老师们、同学们：早上好，今天我在国旗下讲话的主题是“净化校园 弘扬正气 做一个合格的中学生”同学们，你们看春天的阳光多么灿烂，校园里的一切多么的美好。你们在这所美丽的校园中，攀登书山、遨游学海。多么幸运；更值得庆幸的是，还有那么多甘为桥梁、乐做渡工的好老师，悉心教导、倾囊相授。你们拥有无与伦比的优越的外因条件，可是就是有些同学不珍惜这美好的一切，他们给我们的校园抹黑，给我们美丽的校园带来不和谐的音符，可能不少同学听说了，近来极少数同学漠视自己的身份，做出了有悖中学生人格的事，抽烟、斗殴、甚至偷盗敲诈。如果说校园里抽烟是修养问题，打架斗殴是品质问题，那么偷盗敲诈就是犯罪了。校园应该是一方净土，是同学们汲取知识，健全人格，强壮体魄的乐土。不是藏污纳垢的地方，为了净化校园环境，弘扬校园正气，我们将和公安部门一道对参与斗殴的学生一个个追究法律责任，对那些偷盗敲诈的学生也要一个个追究法律责任，对那些游荡校园不思进取大错不犯小错不断的同学也要强化教育，严重的要严肃处理。

高一语文衔接课教案
一、心态调整。 首先，熟知盲点。即了解初高中语文课标的要求差异及变化，做到心中有数，明确衔接过渡的着力点。初、高中语文，考查的重点基本上聚焦在文言文阅读、现代文阅读、诗歌鉴赏、语言运用和作文这五个方面。与初中语文相比，高中语文学习的难度明显在增加了。其具体变化情况简要归类如下： ①语法修辞进考查要求。初中对语法、修辞、文言文词法、句法等知识，侧重于了解，教学中淡化且不作为考查内容;而在高中则重在运用，对语言知识的要求较高，教学中强化且作为重要的考查内容。 ②诗歌阅读增加了难度。从初中的了解到高中的学习，从初中的重在考查积累，到高中强化理解分析，体现了初高中诗歌学习的变化。

They had a giant piano keyboard that you could use your feet to play. But then, instead of playing the sounds of a piano, it played the voices of classical singers!

The grammar of this unit is designed to review noun clauses. Sentences that use nouns in a sentence are called noun clauses. Nominal clauses can act as subject, object, predicate, appositive and other components in compound sentences. According to the above-mentioned different grammatical functions, nominal clauses are divided into subject clause, object clause, predicate clause and appositive clause. In this unit, we will review the three kinds of nominal clauses. Appositive clauses are not required to be mastered in the optional compulsory stage, so they are not involved.1. Guide the students to judge the compound sentences and determine the composition of the clauses in the sentence.2. Instruct students to try to learn grammar by generalizing grammar rules, controlling written practice, and semi-open oral output.3.
