關(guān)于運(yùn)動(dòng)的國(guó)旗下講話稿
第一篇：關(guān)于體育運(yùn)動(dòng)的國(guó)旗下講話稿尊敬的各位老師、親愛的同學(xué)們：大家早上好！今天我講話的題目是：《生命在于運(yùn)動(dòng)》。生命在于運(yùn)動(dòng)”，這是法國(guó)著名思想家伏爾泰的一句名言。運(yùn)動(dòng)的好處非常多，沒(méi)有運(yùn)動(dòng)也就沒(méi)有了生命，運(yùn)動(dòng)能夠帶給我們活力，帶給我們快樂(lè)；運(yùn)動(dòng)，還賦予我們勇敢，我們力量，磨練我們的意志。運(yùn)動(dòng)能減少我們身上多余的脂肪，強(qiáng)壯我們的肌肉，增強(qiáng)身體的抵抗力，運(yùn)動(dòng)還能使我們學(xué)習(xí)精力充沛，精神充足。近20年來(lái)，我國(guó)青少年體質(zhì)持續(xù)下滑，體能素質(zhì)下降，肥胖率上升，近視率居高不下，這種狀況確實(shí)令人擔(dān)憂。少年強(qiáng)則國(guó)家強(qiáng)。我們是國(guó)家的未來(lái)，民族的希望。中華民族的騰飛任重道遠(yuǎn)，我們要以更健康的體魄迎接未來(lái)更激烈的挑戰(zhàn)與困難。作為一名小學(xué)生，我們應(yīng)該積極響應(yīng)國(guó)家的號(hào)召：每天鍛煉一小時(shí)，健康生活一輩子。堅(jiān)持體育鍛煉，我們要上好學(xué)校開展的體育、舞蹈等課程。學(xué)校為我們安排了形式多樣的活動(dòng)課程，保證了我們每天一小時(shí)的鍛煉時(shí)間。我們應(yīng)該堅(jiān)持上好這些活動(dòng)課程，增強(qiáng)我們的體質(zhì)。對(duì)于我們來(lái)說(shuō)，堅(jiān)持體育鍛煉還應(yīng)該做到：認(rèn)真做好每天的課間操，動(dòng)作整齊、到位。有的同學(xué)做操時(shí)動(dòng)作不到位，胳膊該伸直時(shí)不伸直，該側(cè)身時(shí)不側(cè)身，該彎腰時(shí)不彎腰，該跳躍時(shí)不跳躍，這樣，不但起不到鍛煉的目的，久而久之，還養(yǎng)成了做事不認(rèn)真的壞習(xí)慣。
