二月國(guó)旗下講話稿
講話稿有廣義和狹義之分。廣義的講話稿是人們?cè)谔囟▓?chǎng)合發(fā)表講話的文稿；狹義的講話稿即一般所說(shuō)的領(lǐng)導(dǎo)講話稿，是各級(jí)領(lǐng)導(dǎo)在各種會(huì)議上發(fā)表帶有宣傳、指示、總結(jié)性質(zhì)講話的文稿。二月國(guó)旗下講話稿應(yīng)該怎么寫(xiě)？二月國(guó)旗下講話稿篇一： 老師們、同學(xué)們:高三的同學(xué)們，高三是人生征途中的重要一站，千萬(wàn)不要把太多的精力和時(shí)間消耗在一時(shí)的享樂(lè)當(dāng)中，當(dāng)你竭盡自己的最大努力去為實(shí)現(xiàn)自己的夢(mèng)想而奮斗，你將收獲超出你預(yù)期的成果。高三是享受拼搏、奮斗人生的最佳時(shí)光?；旧倌辏跎?，指點(diǎn)江山，激揚(yáng)文字，敢與天公試比高。年輕是我們的資本，成功是我們的追求，奮斗是我們的宣言，愈挫愈勇是我們的氣魄。人們常說(shuō)：此時(shí)不搏何時(shí)搏；就是說(shuō)，拼搏要抓住時(shí)機(jī)。幸福在于拼搏，享受在于拼搏。拼什么？拼效率，有了效率才會(huì)有成功；拼心態(tài)，愉悅的心態(tài)激活大腦的思維；拼意志，頑強(qiáng)的毅力不畏懼任何失?。黄礉摿?，人們往往會(huì)被自己巨大的潛力驚得目瞪口呆。高考的壓力固然很重，但沒(méi)有壓力的生活就像沒(méi)有風(fēng)的帆——會(huì)空虛；沒(méi)壓力的青春就像沒(méi)有春光的花——會(huì)枯萎；沒(méi)有壓力的生命就像沒(méi)有日光的極地——黯然失色。所以我們要勇敢地面對(duì)壓力，壓力就是我們前進(jìn)的動(dòng)力，壓力就是我們前進(jìn)的道路上的鋪路石，就是我們笑傲考場(chǎng)的籌碼。
