关于期中考试的国旗下讲话稿
关于期中考试的国旗下讲话稿一：老师们，同学们，大家上午好!今天我讲话的题目是：提高复习效果，迎接期中考试。同学们，按照教育局工作安排，我们将在本大周进行期中考试，为了提高复习效果，在期中考试中取得满意的成绩，在此我给同学们提以下几点要求。一、端正思想，充分认识期中考试的重要性。离期中考试只有五天的时间了，时间对于我们来说相当紧迫，希望全体同学们要以期中考试复习为重心，以争取期中考试取得好成绩为目标，把必须要做的事情和可做可不做的事情清楚地分开，抓紧时间，认真复习，提高复习质量和效率。二、认真准备，合理安排复习时间和计划。我希望每位同学从今天起，要充分地利用晚自习时间及早读时间，根据每个学生的实际情况出发，安排一个切实可行的复习计划。什么时间该复习哪一个科目哪个知识点，要达到什么目标，都要心中有数，“不打无准备之仗”，谁早准备，谁就拥有学习的主动权;谁拥有的时间多，谁就拥有考试的成功。
关于期末考试动员国旗下讲话稿
同学们：又到了收获的季节，相信我们又多了一份紧张、期待。我们的紧张，来源于父母那热切的目光; 来源于老师那谆谆的话语; 也来源于我们面对考试的那份压力。有了这份必要的紧张，我们的思维会更敏捷, 我们的表现会更出色。我们期待，是因为我们到了验证自我的时刻，凭着这种积极的心态，我们能够做到更加认真，我们能充分利用考试过程中的分分秒秒做足迎考的准备。同学们，期末考试的进步离我们越来越近了，借此机会我向大家提出以下三点建议：第一：目标决定结果。大家都知道，成功的道路必定是有明确的目标的。我要说的是：目标有多远，我们就能走多远。我们要对得起我们的付出，无悔于我们的青春! 我想，作为各年级的学子，我们的目标就是一个：考出优异成绩，打下坚实基础!第二：态度决定结果。记得有一句歌词：“不经历风雨，怎能见彩虹，没有人能随随便便成功。”没有压力就没有动力，没有动力就发挥不出一个人蕴藏的潜力!面对考试的压力，我们必须强化如下态度：一是勤奋的态度
关于期末考试国旗下讲话稿
期末复习总动员---第19周国旗下讲话稿 亲爱的老师，同学们：大家早上好!时光如梭，岁月如歌，转眼间，我们一个学期的学习即将结束了!再过两 个星期左右，我们就要迎来本学期的期末考试。期末考试是我们一学期学习成果的展示，是所有同学摘取果实的时候。那么，我们应该怎样去做呢？首先，我们一定要珍惜时间。我们只要能够在老师的指导下，认认真真地听好每一节复习课，踏踏实实地做好每一道习题，仔仔细细地完成每一次作业，那么，你的成绩就一定会有明显的提高。请同学们抓紧点滴时间，暂时少玩一玩，回家后少看一会儿电视，全力以赴地投入到总复习中去。今日事，今日毕，千万不要抱有任何侥幸心理，不要等到拿到成绩报告单时才追悔莫及。其次，我们要全面复习不疏漏。一个学期中，我们学习的知识很多，我们要在老师的指导下，静下心来，扎扎实实地进行全面和系统的复习，要一个单元一个单元，一篇课文一篇课文有计划的复习。在全面复习的基础上，我们还要找准自己的薄弱点，抓住每门功课的关键点，每个单元的重点和难点，有目的地进行归纳、整理、训练。同时，我们还要讲究复习方法，复习一个知识点，就要真正掌握，还要学会运用，把课内外知识结合起来，举一反三，注重复习的效果。
关于高中期末考试国旗下讲话稿
老师们，同学们：我国旗下的讲话的主题是《向期末考试做最后的冲刺》时光如梭，岁月如歌，不知不觉，紧张、忙碌而又充实的一个学期即将结束。本周四、五及下周一就要进行期末考试了。大家可以算算距考试还有多长时间，俗话说，“临阵磨枪，不快也光”,因此，请同学们抓紧时间，劳逸结合，认真进行复习。我希望同学们深刻领会有关内容，搞好复习，考出好成绩。下面我给同学们提几点建议。一、正确认识，高度重视。期末考试不仅是对同学们一个学期以来学业成果的一次盘点，更是对每个人综合素质的一次挑战，是对同学们自信心、自觉性、意志力的一次考验，也是同学们对老师辛勤工作予以回报的时刻。希望同学们克服过于紧张、焦虑的情绪，沉着冷静，以从容自信的态度面对期末考试。我不能要求每个人都成为优胜者，但我希望大家做一名追求进步、超越自我的勇敢者。希望同学们能够抓住机会，充分展示自己，在这收获的季节摘取胜利的果实。
初中期末考试前国旗下讲话稿
一天，一个年轻人在沙滩上散步，无意间，他转了一下头，却发现自己走过的两行脚印是弯曲的。他很不解,刚才自己明明走得很直,脚印怎么会弯曲呢?这时,他看到不远处有一块礁石,于是朝着礁石的方向走去.....等他再回头看时,发现沙滩上印着两行清晰笔直的脚印......其实，在生活中,不论我们做什么事,心中都要有一个目标。只有这样,才会找准方向、少走弯路。期末复习时间紧张，更应如此。 这样的目标，我建议大家定的适当地高一些，这样才能激励自己，给自己以动力。有这样一则寓言：一只小鸡看见苍鹰在高高的蓝天上飞过，十分的羡慕，于是他问母鸡：妈妈，我们也有一对大翅膀，为什么不能像鹰那样高飞呢? 真是个小傻瓜，母鸡回答说，飞得高有什么用处，蓝天上没有谷粒，也不会有虫子啊!.是的，如果你的目标不是蓝天，你就永远不会飞翔。其次.制定一个切实可行的复习计划凡事预则立，不预则废。我们的同学有没有给自己的复习定个计划呢?每一位同学除了跟着老师的进度，按照老师的要求复习外，还应根据自己的情况，给自己的薄弱学科，和各学科中的薄弱章节适当的增加些复习时间和练习。最后. 要有脚踏实地的有效行动
3篇期末考试动员国旗下讲话稿
同学们：当早晨的第一缕阳光洒向大地， 我们又迎来了新的一天，新的一周。这一周是最后冲刺的一周。因为下周我们就要进行期末考试了。其实从上个星期开始，我们中就有许多同学已经制定了复习计划，并按计划开始复习了。今天，我不想谈关于复习方法或是复习内容之类的问题。今天，我想和大家说的是关于“自信心”的问题。有这样一句格言：“对自己说，我行!” 这虽是一句朴实无华的格言，但对一些人来说，要做到这一点却实在不容易。那么，是什么妨碍了你的自信，压抑了你的勇气呢?我想，有这么几点可以帮助你树立积极、乐观、自信的精神。一、避免使用否定自己的语言。“我不行。”“我是个没用的人。”“我很笨。”你是不是会时常说出这样的话?如果是的话，要知道，你是在进行一种负面的自我暗示，使自己的情绪充满失败感。也许你会说这是为了体现一种谦虚，但是，“累积暗示效果”会使你产生自卑。也会让听到你说话的人，认为你真的是个没用的人。所以，我们一定要避免使用否定自己的语言，要自信而理直气壮地说：“我行!”
