尊敬的老師、親愛的同學(xué)們:大家上午好!今天,我國(guó)旗下講話的題目是《踐行志愿服務(wù),辦好文明校運(yùn)》。在XX年北京奧運(yùn)會(huì)和XX年南京亞青會(huì)上,有一群人,他們遍布賽場(chǎng)內(nèi)外,甚至大街小巷;人們親切地稱他們“小紅帽”、“紅馬甲”;他們互不相識(shí),但有著共同的信仰:奉獻(xiàn)、友愛、互助、進(jìn)步;他們沒有冠軍的光環(huán),但更值得尊重;他們就是青年志愿者。XX年,共青團(tuán)中央、中國(guó)青年志愿者協(xié)會(huì)共同決定把3月5日作為“中國(guó)青年志愿者服務(wù)日”。把“志愿者”定義為:志愿貢獻(xiàn)個(gè)人的時(shí)間、精力,在不謀求物質(zhì)報(bào)酬的前提下,從事社會(huì)服務(wù)事業(yè),為推動(dòng)社會(huì)進(jìn)步提供服務(wù)的人。也許“不謀求物質(zhì)報(bào)酬”、“推動(dòng)社會(huì)進(jìn)步”這些定義聽起來(lái)很大、很遠(yuǎn),甚至讓人懷疑是不是要求太高了?
尊敬的各位老師,親愛的同學(xué)和家長(zhǎng)們:時(shí)光淺淺,冬日漫漫,附中師生,好久不見,你們還好嗎?這段時(shí)間大家辛苦了!反反復(fù)復(fù)的疫情,致使居家網(wǎng)課成了學(xué)習(xí)的常態(tài),它對(duì)你的學(xué)習(xí)和生活有影響嗎?說(shuō)沒有,絕對(duì)是假的。離開了學(xué)習(xí)的專供場(chǎng)所——校園,離開了窗明幾凈的教室,離開了朝夕陪伴的老師,離開了團(tuán)結(jié)友好又卷的厲害的同伴,在家學(xué)習(xí),說(shuō)實(shí)在的,缺少了一種氛圍。人們常把一個(gè)陌生的溫馨的環(huán)境比喻成家,家,就是一個(gè)港灣,是一個(gè)身體和靈魂的棲息地,可是疫情硬是讓我們把家變成了學(xué)校,把客廳,臥室變成了教室。沒有了教室課堂的約束,沒有了老師目光的緊盯和交流,你的坐姿是否端正?一節(jié)課你是否一直全神貫注?有沒有邊聽邊吃邊喝的時(shí)候?有沒有起床后重返被窩的現(xiàn)象?和同學(xué)聊過(guò)天沒?作業(yè)每次都實(shí)實(shí)在在獨(dú)立完成嗎?一天下來(lái)除了利用手機(jī)電腦學(xué)習(xí),刷過(guò)抖音沒?聽過(guò)歌曲沒?玩過(guò)游戲沒?但愿這些都是我們無(wú)端的猜想和假設(shè),是我們?cè)阼饺藨n天,老師們很不放心啊!一直擔(dān)憂線上學(xué)習(xí)的效率和效果。
說(shuō)時(shí)遲,那時(shí)快,薛霸的棍恰舉起來(lái),只見松樹背后雷鳴也似一聲,那條鐵禪杖飛將來(lái),把這水火棍一隔,丟去九霄云外,跳出一個(gè)胖大和尚來(lái),喝道:“灑家在林子里聽你多時(shí)!”……兩個(gè)公人看那和尚時(shí),穿一領(lǐng)皂布直裰,跨一口戒刀,提起禪杖,掄起來(lái)打兩個(gè)公人。林沖剛才讓開眼看時(shí),認(rèn)得是魯智深。
牛是家鄉(xiāng)的風(fēng)景。春天的圖畫里少不了雨、離不開牛、缺不得迎春花。一犁春雨半畝洼,蓑衣斗笠半袖花,春風(fēng)應(yīng)時(shí)而至,春光爛漫無(wú)邊,翠綠墨綠嫩綠鵝黃綠,梨花李花桃花梔子花,所有的草葉花蕊、溪流石泉都滴著青春的原汁。
米吃多了,就有了想法。詩(shī)人說(shuō)“米是漫山遍野的精靈,是生長(zhǎng)綠色的種子,是陸地結(jié)的珍珠”,我也有這個(gè)感覺。有時(shí)我看到掉在桌上的一粒米,會(huì)產(chǎn)生一番聯(lián)想:這粒米,不知道是哪粒種子被種在土里,經(jīng)過(guò)了多少風(fēng)霜雨雪,又被哪個(gè)農(nóng)民精心養(yǎng)育,澆水、施肥、捉蟲、打藥,頂著酷暑烈日收割了來(lái),再冒著酷暑高溫脫了粒。脫一遍還不算,再脫一層皮,再脫一層皮,成為白白亮亮的精米,大有緣法落到我的飯碗里,結(jié)果不等它入口,就被輕輕拋棄,假如這米有靈,不知道會(huì)不會(huì)傷心?
