人教版高中歷史必修3宋明理學(xué)說課稿3篇
陸王心學(xué)與程朱理學(xué)相比有何異同？生 不同點：在理的內(nèi)涵上不同，程朱理學(xué)認(rèn)為“理”是貫通于宇宙、人倫的客觀存在，是一種普遍的規(guī)律準(zhǔn)則；陸王心學(xué)認(rèn)為心即理，是“良知”，認(rèn)為人心便是世界萬物的本原。方法上也有不同：前者向外追究，“格物致知”；后者向內(nèi)探求，“發(fā)明本心”以求理，克服私欲、回復(fù)良知。生 相同點：都提出了一個宇宙、社會、人生遵循的“理”。師 對。程朱理學(xué)是客觀唯心主義，陽明心學(xué)是主觀唯心主義。這兩者的分歧是理學(xué)范圍內(nèi)的分歧，其基本思想是一致的。師 宋明理學(xué)與漢唐以前的儒學(xué)比較，最大的特點在于批判地吸收了佛教哲學(xué)的思辨結(jié)構(gòu)和道教的宇宙生成論，將儒家的倫理學(xué)說概括升華為哲學(xué)基本問題。其實質(zhì)是把佛、道“養(yǎng)性”“修身”引向儒家的“齊家”“治國”“平天下”，對儒家的綱常道德給予哲學(xué)論證，使之神圣化、絕對化、普遍化，以便深入人心，做到人人遵而行之。

國旗下講話：把信心留給自己
同學(xué)們，你是否為了偶然的失敗而懊意苦惱，難有東山再起的雄心壯志？你是否曾經(jīng)為了前途渺茫而黯然傷神？如果有過，那么你又是否思考過，把信心留給自己，重新讓自己昂首挺胸地奔向自己的錦繡前程呢？人生如海上行舟，不知何時就會遭到惡浪和風(fēng)暴的襲擊。既然我們來到人間，就應(yīng)該用青春的鐮刀去披荊斬棘。懦弱的人站在雨中怕淋濕，站在陽光下怕曬黑，如此命運只能讓他們在山腳下徘徊。恰恰相反，勇敢的水手從來不懼怕風(fēng)高浪險，因為他們深知涉淺水者得魚蝦，涉深水者得蛟龍，年輕人不要畏首畏尾。請在自己心中樹立一個永恒的信念——沒有比腳更長的路，沒有比心更高的山。是的，腳比路長，遠方無論有多么遠，經(jīng)過雙足跋涉，終會抵達，人生亦是如此。我們不怕目標(biāo)高遠，只怕沒有追尋的勇氣、熱情和執(zhí)著。只要心頭時時燃燒著堅定的信念，一往無前的行進下去，就會驚訝的發(fā)現(xiàn)--很多所謂的遠方并不那么遙遠。

國旗下講話：保護環(huán)境從自己做起
老師，同學(xué)們：六月，不僅有大家熟悉的兒童節(jié)和父親節(jié)，還有一個特別有意義的日子——世界環(huán)境日。一直以來，我們賴以生存的環(huán)境，引起了許多有識之士的極大關(guān)注。1972年6月5日，在人類環(huán)境會議上，通過了著名的《人類環(huán)境宣言》。同年10月，第27屆聯(lián)合國大會通過決議，將以后每年的6月5日定為世界環(huán)境日。我們都知道美麗的自然環(huán)境，能帶給我們愉快的心情，帶給我們學(xué)習(xí)和工作的良好氛圍。但是，人們在享受大自然的恩惠時，卻粗心地忘記了去保護這些美麗的景色，以至于如今，生態(tài)環(huán)境不斷惡化：森林退化，塵土飛揚，水土流失，洪水肆虐，酸雨赤潮，南極空洞……各種環(huán)境問題接踵而至。聯(lián)合國環(huán)境署曾發(fā)布環(huán)境調(diào)查結(jié)果：地球上有億人口生活在混濁的空氣中，12億人口生活缺水，12%的哺乳動物和11%的鳥類瀕臨滅絕，每年地表土壤流失四百億噸，森林以每年450萬公頃的速度消失……這些觸目驚心的數(shù)字仍在不斷增長著。這為我們敲響了警鐘：保護環(huán)境已刻不容緩!
