    敬爱的老师,亲爱的同学们: 大家早上好!我是高一(2)班的李xx,很荣幸能在此发言,我今天国旗下讲话的题目是《把握此刻,心向远方》。路还是昨天的路,但里程碑已是新的;歌还是昨天的歌,但今天唱出的更动听;太阳还是昨天的太阳,但它放射出的却是全新的光芒。不知不觉我们已走进青春的花季,这是人生中最黄金的年龄。孔子说:“学而时习之,不亦说乎?”可在这美好的求学生涯中,有些同学却有点迷茫,时常想着作业该怎么写才来得及,担心考试是否通得过,耳边总是萦绕着老师的训诫和家长的唠叨……于是,你开始烦恼,开始抱怨,开始懊悔,开始厌倦。你消极怠工,不求上进,最后蹉跎了光阴,被自己的梦想抛弃。在吃饭的时候想着睡觉,在睡觉的时候想着吃饭,在正确的时间没有做正确的事情,错位的选择只能带来失意的人生。年轻的心需要一个远大的梦想。请检查一下自己:我的梦是否依然,我的脚步是否坚定?千里之行,始于足下。也许我们不清晰远方有多远,但我相信脚下的路正通向远方。我们只有迎着朝阳奔跑,才不会在夕阳中忏悔。

    老师们,同学们:大家上午好!今天我国旗下讲话的题目是“以梦之名,心向远方”。又是一年丹桂飘香之时,我们站在九月的尾巴上,期待着十月的盛放。在不久前的开学典礼上,我们感受守望与传承的力量。XX年六月的高考早已落下帷幕,高三的学长学姐们取得了辉煌的成绩,终于走向了属于他们的梦想和远方。而今天,十月的选考就在眼前,我们又将传承这一份拼搏精神,走向属于我们自己的未来。我想起《牧羊少年的奇幻之旅》中有这样一句话:“没有任何一颗心在追求梦想的时候感到痛苦。”那是因为我们心中有梦,因此面对艰难险阻,坦然无惧,纵使前路漫漫,亦不彷徨。高中三年,九百多个日日夜夜,我们用拼搏的青春,编织成对未来的向往。一步一步,走向属于自己的精彩。正如三毛所言:“我们一步步走下去,踏踏实实地走下去,永不抗拒生命给我们的重负,才是一个勇者。”诚然,高中岁月会有纠结,会有彷徨,亦会有跌倒,但更重要的是我们拼搏过,奋斗过。奋斗的青春最美丽,追梦的青春最勇敢。理想万岁,青春无悔,是因为勇敢追逐过,所以过程比结果更值得珍藏

    第五周国旗下讲话稿:有一种力量叫成长

    尊敬的各位老师,亲爱的同学们:大家早上好!今天我演讲的题目是《有一种力量叫成长》。雄鹰之所以能自由翱翔,是由于它练就了健壮有力的翅膀大河之所以能奔腾浩荡,是因为它吸纳了山泉小溪的力量。我们的成长固然离不开老师的教诲、家长的帮忙,殊不知,我们的年轻的心房就是一股火苗,一缕阳光。驱走寒冷压抑、排遣孤独彷徨,照样把我们自己的青春照亮。有一种力量叫自信刚强。自卑自负之心不可有,自信自强之心不可无。作为一名高中生,自信自然不可缺少,面对学习中一道又一道的难题,有时我们并不缺少实力,而是少了一样东西--自信。自信会带给我们成长,只有足够自信,方能笑傲考场,笑对人生。要记住,自信是朵开不败的花。有一种力量叫谦逊向上。低调做人,高调做事,心儿永远向着未来。谦逊因难能,所以可贵。当我们能够做到胜不骄,败不馁,对我们来说这便是一种成长。正如物理学家牛顿说过:“我之所以能看得远,是因为我站在巨人的肩膀上。”谦逊是一种能让我们学无止境的力量。
