国旗下的讲话：文明礼仪伴我行
这篇《国旗下的讲话：文明礼仪伴我行》是由整理提供的，请大家参考！国旗下的讲话：文明礼仪伴我行老师们、同学们：早上好!今天我讲的题目是《文明礼仪伴我行》。梁启超说过：“少年智则国智，少年强则国强。” 在这里我却要大声说：“少年文明，则国家昌盛。”在一个国家中个人是主体，对于个人来说什么最重要呢？我想首先应该是具备文明素质，只有当每一个人都具备了文明素质，那么这个国家的整体素质才能提高。曾看到这样一则报道，说的是新加坡，新加坡是一个通用英语的国家，这个国家的公共场所的各种标语大多是用英语书写。但其中的一些文明礼貌的标语，如“不准随地吐痰”、“禁止吸烟”、“不准进入草坪”等却用中文书写。为什么呢？人家回答：“因为有这些不文明行为的大多数是中国大陆的游客。”为此，到新加坡考察的一位中学校长语重心长地说：“不文明行为也是国耻！”。
3月份国旗下讲话：文明礼仪伴我行
敬的老师们、同学们：你们好！我给大家演讲的题目是《文明礼仪伴我行》。梁启超曾说过，少年智则国智，少年强则国强。我却在这里要大声说，少年文明，国家昌盛。在一个国家中个人是主体。对于个人来说什么最重要呢？我想首先应该是具备文明素质，只有当每一个人都具备了文明素质，那么这个国家的整体素质才能提高。不久前，曾看到这样一则报道，说的是新加坡，新加坡是一个通用英语的国家，这个国家的公共场所的各种标语大多是用英语书写。但其中的一些文明礼貌的标语，如“不准随地吐痰”、“禁止吸烟”、“不准进入草坪”等却用中文书写。为什么呢？人家回答：“因为有这些不文明行为的大多数是中国大陆的游客。”为此，到新加坡考察的一位中学校长语重心长地说：“不文明行为也是国耻！” 不知大家是否记得，中央电视台曾经报道，国庆节后的天安门广场，随处可见口香糖残迹，40万平方米的天安门广场上竟有60万块口香糖残渣，有的地方不到一平方米的地面上，竟有9块口香糖污迹，密密麻麻的斑痕与天安门广场的神圣和庄严形成了强烈反差。

老师们、同学们：早上好!今天我讲的题目是《文明礼仪伴我行》。梁启超说过：“少年智则国智，少年强则国强。” 在这里我却要大声说：“少年文明，则国家昌盛。”在一个国家中个人是主体，对于个人来说什么最重要呢?我想首先应该是具备文明素质，只有当每一个人都具备了文明素质，那么这个国家的整体素质才能提高。曾看到这样一则报道，说的是新加坡，新加坡是一个通用英语的国家，这个国家的公共场所的各种标语大多是用英语书写。但其中的一些文明礼貌的标语，如“不准随地吐痰”、“禁止吸烟”、“不准进入草坪”等却用中文书写。为什么呢?人家回答：“因为有这些不文明行为的大多数是中国大陆的游客。”为此，到新加坡考察的一位中学校长语重心长地说：“不文明行为也是国耻!”。以上的事例表明，文明其实是由点滴细节构成的，反思我们的所作所为，可见文明离我们还有一段距离。在我们身边，在一部分同学身上，还存在着一些不文明的行为。例如，在我们的校园内、楼梯上总能见到与我们美丽的校园极不和谐的纸屑，教室里、校园内食品袋、方便面盒随处可见，甚至有的同学认为：反正有值日的同学和清洁工打扫，扔了又何妨

人教部编版七年级下册写作语言简明教案
师小结：以简代繁，是让语言简明的又一方法。除了常用的人称可以替代，还可以对不必要的具体内容进行概述，以达到简明的效果。替代的词句要巧，既要简洁，又不能改变原意。由此我们可以总结出语言简明的另一种方法：“语言简明”的方法：④巧用替代法——善于概括，巧用指代。师补充：汉语是一种非常丰富的语言，它的许多表达形式都是以简明为原则而形成的，像成语、简称、紧缩句、合说等。我们在运用语言时，可以适当地选用这些表达形式，使语言达到简明。需要注意的是，简明与否不能单纯以字数多少为标准，要从语言表达的需要出发，当简则简，当繁则繁。不能为了“简”而影响“明”，甚至让人产生误解。归纳这节课的学习要点，让学生将其内化为自身的语言意识并参与写作实践，学以致用，训练使语言“简明”的能力，培养良好的写作习惯。

求证：直角三角形的两个锐角互余．解析：分析这个命题的条件和结论，根据已知条件和结论画出图形，写出已知、求证，并写出证明过程．已知：如图所示，在△ABC中，∠C＝90°.求证：∠A与∠B互余．证明：∵∠A＋∠B＋∠C＝180°(三角形内角和等于180°)，又∠C＝90°，∴∠A＋∠B＝180°－∠C＝90°.∴∠A与∠B互余．方法总结：解此类题首先根据题意将文字语言变成符号语言，画出图形，最后再经过分析论证，并写出证明的过程．三、板书设计命题分类公理：公认的真命题定理：经过证明的真命题证明：推理的过程经历实际情境，初步体会公理化思想和方法，了解本教材所采用的公理，让学生对真假命题有一个清楚的认识，从而进一步了解定理、公理的概念．培养学生的语言表达能力．
平行线的性质定理和判定定理教案教学设计
1、互逆命题：在两个命题中，如果第一个命题的条件是第二个命题的 ，而第一个命题的结论是第二个命题的 ，那么这两个命题互逆命题，如果把其中一个命题叫做原命题，那么另一个命题叫做它的 .2、互逆定理：如果一个定理的逆命题也是 ，那么这个逆命题就是原来定理的逆定理.注意(1)：逆命题、互逆命题不一定是真命题，但逆定理、互逆定理，一定是真命题.(2)：不是所有的定理都有逆定理.自主学习诊断：如图所示：(1)若∠A= ，则AC∥ED，( ).(2)若∠EDB= ，则AC∥ED，( ).(3)若∠A+ =1800，则AB∥FD，( ).(4)若∠A+ =1800，则AC∥ED，( ).
利用计算器进行有理数的计算教案教学设计
计算器的面板是由键盘和显示器组成的。显示器是用来显示输入的数据和计算结果的装置。显示器因计算器的种类不同而不同，有单行显示的，也有双行显示的。在键盘的每个键上，都标明了这个键的功能。我们看键盘上标有的键，是开机键，在开始使用计算器时先要按一下这个键，以接通电源，计算器的电源一般用5号电池或钮扣电池。再看键，是关机键，停止使用计算器时要按一下这个键，来切断计算器的电源，是清除键，按一下这个键，计算器就清除当前显示的数与符号。的功能是完成运算或执行命令。是运算键，按一下这个键，计算器就执行加法运算。
北师大初中七年级数学下册平行线的性质教案
解析：平行线中的拐点问题，通常需过拐点作平行线．解：(1)∠AED＝∠BAE＋∠CDE.理由如下：过点E作EG∥AB.∵AB∥CD，∴AB∥EG∥CD，∴∠AEG＝∠BAE，∠DEG＝∠CDE.∵∠AED＝∠AEG＋∠DEG，∴∠AED＝∠BAE＋∠CDE；(2)同(1)可得∠AFD＝∠BAF＋∠CDF.∵∠BAF＝2∠EAF，∠CDF＝2∠EDF，∴∠BAE＋∠CDE＝32∠BAF＋32∠CDF，∴∠AED＝32∠AFD.方法总结：无论平行线中的何种问题，都可转化到基本模型中去解决，把复杂的问题分解到简单模型中，问题便迎刃而解．三、板书设计平行线的性质：性质1：两条平行线被第三条直线所截，同位角相等；性质2：两条平行线被第三条直线所截，内错角相等；性质3：两条平行线被第三条直线所截，同旁内角互补．平行线的性质是几何证明的基础，教学中注意基本的推理格式的书写，培养学生的逻辑思维能力，鼓励学生勇于尝试．在课堂上，力求体现学生的主体地位，把课堂交给学生，让学生在动口、动手、动脑中学数学
