    XX慶元旦校長國旗下講話稿4篇

    慶元旦國旗下講話稿1各位老師,各位同學:大家早上好!今天我國旗下演講的題目是《新年新起點》。在本周的日歷上,有一個光輝的日子——1月1日,這標志著華夏神州又增添了一道年輪,標志著時代的航船乘風破浪,偉大祖國又迎來了充滿希望的一年。1月1日又稱元旦,“元”是開始,第一之意;“旦”是早晨,一天之意?!霸本褪且荒甑拈_始,一年的第一天。從字面上看,“旦”字下面的一橫代表著波濤澎湃的海面,一輪紅日正從海上噴薄而出放射著燦爛輝煌的光芒,這個象形字生動地反映了旭日東升的形象。把“元旦”合在一起,就是要人們以蓬勃的朝氣和奮發(fā)的斗志來迎接嶄新的一年。東晉詩人陶淵明曾有過這樣的感嘆:“盛年不重來,一日難再晨,及時當勉勵,歲月不待人”。我們也不乏這種緊迫感。我們是青年,青年是生命中的春天,是早晨八九點鐘的太陽。我們是跨世紀的一代,成學業(yè)于本世紀,成事業(yè)于新紀元,我們將成為時代洪流中搏擊風浪的勇士。生逢此時,榮幸又艱巨。讀書,是一切成大事者的必由之路,是一切創(chuàng)造的基礎。認真讀書是時代的要求。我們要用勤奮和汗水夯實學業(yè)大廈的地基,用拼搏向時光索取價值,用雙手為鮮艷的五星紅旗添彩。只有這樣,才無愧于華夏子孫,才能肩負起承前啟后,繼往開來的歷史使命。

    尊敬的各位老師、親愛的同學們:大家早上好!光陰似箭,歲月如歌。轉眼間,我們即將近揮別難忘而輝煌的XX年,邁進更加令我們期待和憧憬的XX年。 在新的一年將近要開始之際,我們每個人心里充滿的是激情,是自豪,是刻骨銘心的記憶和留戀。每年的1月1日為元旦,是新年的開始?!霸?,按單個字來講,“元”是或開始的意思,“旦”字的原意是天亮或早晨。我國在發(fā)掘大汶口文化遺物中,發(fā)現(xiàn)一幅太陽從山顛升起,中間云煙繚繞的圖畫。經(jīng)考證,這是我國最古老的“旦”字寫法。后來,在殷商的青銅器鑄銘上,又出現(xiàn)了被簡化的“旦”字?!暗弊质且詧A圓的太陽來表示的?!叭铡毕旅娴摹耙弧弊直硎镜仄骄€,意為太陽從地平線上冉冉升起。但是,我國古人說的元旦,卻并不是公歷的1月1日,而是正月初一,又稱元日。中國只是到了中華民國以后才逐漸改用公元紀年。因此,中國農(nóng)歷的正月初一既春節(jié)比公歷的元旦更有節(jié)日氣氛。
