Now he became successful again.Walter Haddon said, “Music is the medicine of a troubled mind.” Music contains such a pleasant and inspiring force. Music gave him courage and bravery.

At the same time, we all go through various periods when we feel sad or alone. During those times, music can help us in the same way that it helped him. I hope we all will somehow begin to treasure music and make it a part of our life.

人教版高中語文必修3《馬嵬（其二）》教案2篇
結合歷史自古以來，江山美人歷來都是引無數(shù)英雄豪杰競折腰的，如果說英雄選擇了美人卻丟了江山，把所有罪名都歸結于“女人是禍水”。但是，紂王無道，和有了妲己有必然的聯(lián)系嗎？有人說妲己壞透了，壞透了的妲己如果不是取得紂王的信任是壞不起來的，紂王聽信了妲己的讒言，聽與不聽決定權在紂王，而不在妲己。強勢永遠在紂王一邊。再來看看西施和楊貴妃：西施是作為越國貢獻給吳國的供品來到吳王夫差的身邊的，楊貴妃更是先是李隆基的兒媳婦被看中而得寵的。所以，西施和楊貴妃這兩個可憐的女人根本沒有自己的獨立選擇，沒有獨立的愛情，如果沒有西施，就會有南施，或北施；如果沒有楊貴妃，就會有李貴妃，王貴妃，總之什么施，什么妃是不能少的，因為那是吳王和李隆基的需要。
第二學期開學安全第一課（國旗下講話）
第二學期開學安全第一課（國旗下講話）老師同學們：大家好！今天是新學期的第一天，我們懷著激動的心情，邁著矯健的步伐回到學校，迎接新學期的挑戰(zhàn)。今天我將利用一節(jié)課的時間圍繞“安全”這個話題和大家談起。因為安全是我們快樂學習與生活的前提，是我們每一個人的心愿。在此，我向全體同學提出以下建議，讓我們行動起來，為安全而努力，讓安全與我們同行。同學們，生命只有一次、健康不能重來。生命安全就掌握在我們自己手中。安全不僅關系我們個人、更關系到我們身后的家庭、學校、整個社會和整個國家。珍愛生命，增強安全意識，讓快樂與幸福伴隨我們的童年。今天我與同學們一起交流幾個方面的安全問題。一、交通安全1、要遵守交通法規(guī)，基本常識有：行人靠右行，不闖紅燈，不跨越護欄，橫穿公路時要左顧右盼看是否有車輛經過，不脫把騎車，不騎“英雄”車，不跳車，不扒車。2、十二周歲以下的學生不準騎自行車。3、不乘坐黑車，因為黑車是“三無”車，有諸多不安全系數(shù)，出了安全問題，費用難以保證，更談不上賠償。
中班語言《小羊和狼》說課稿
《小羊和狼》這則童話故事主要講了一個小羊去河邊喝水，大灰狼要吃掉小羊，大象伯伯幫助了小羊，將小羊救下來的故事。圖片畫面色彩鮮艷，能夠吸引幼兒的注意力，而且篇幅短，容易理解和感受，能夠發(fā)揮幼兒的想象力，符合綱要中“鼓勵幼兒大膽、清楚地表達自己的想法和感受，嘗試說明、描述簡單的事物或過程，發(fā)展語言表達能力和思維能力?！钡囊?，并且能很好的將樂于助人這一優(yōu)異品質傳輸給幼兒，在他們成長的道路上有很大的幫助。而且中班幼兒有了一定的生活經驗，具備主動積極的特性，思維能力也在不斷的增強，語言能力也有了很大的發(fā)展，能基本講清楚自己所看到的事物及其變化，因此這篇《小羊和狼》非常適合在中班進行教學，以拓展他們的語言能力、思維能力以及良好品質的養(yǎng)成，能在活動后服務于幼兒的生活中。
大班音樂《大浪和小浪》說課稿
（一）內容的選擇新《綱要》上說：“要引導幼兒接觸周圍環(huán)境和生活中美好的人、事、物，給幼兒自由表現(xiàn)的機會，鼓勵幼兒用不同的藝術形式大膽地表達自己的情感、理解、想象。”臺州是一個非常美麗的海濱城市，這里的孩子們都見過大海，能經常和家人一起到海邊游泳、玩耍，所以，他們對于大海有著非常豐富的感性經驗。特別是海面上此起彼伏的海浪和“嘩嘩”的海浪聲，更是給孩子們留下了非常深刻的印象。因此，我選擇《大浪和小浪》這個活動內容。（二）目標的制定幼兒是在蘊涵豐富審美的刺激中成長起來的，能在適宜的環(huán)境中選擇并獲取適合他們發(fā)展的信息，并主動地在藝術活動中表現(xiàn)出來，以展現(xiàn)他們的個性。本次活動的目標為：1、辨別音樂的低潮和高潮，通過適當?shù)姆椒ū憩F(xiàn)音樂不同的力度。2、感受音樂中情緒起伏的變化，盡情地融入游戲情景，在音樂中情緒宣泄得到平衡與滿足。（三）活動的準備根據大浪和小浪的特點，我選取了兩段不同性質的音樂：小浪的音樂輕柔、緩慢并以還浪聲作背景，聽后給人以非常優(yōu)美、舒適的感覺；大浪的音樂比較急速，聽后頓時能激發(fā)幼兒的情緒。為了給幼兒創(chuàng)造一個逼真的環(huán)境，我選擇了藍色的綢布來輔助幼兒進一步理解音樂，讓幼兒的情緒得以宣泄。二、說重點難點（一）重點：活動的重點是引導幼兒用適當?shù)姆椒ū憩F(xiàn)音樂不同的力度?；顒忧?，幼兒對大浪小浪已有了一定的感觀經驗，通過了幼兒之間的談話、教師的朗誦講述、音樂的欣賞、身體動作的表現(xiàn)、游戲等形式，幼兒對大浪小浪音樂不同的力度有了較深的理解。
小班認知《1和許多》說課稿
認識“l(fā)”和“許多”是幼兒認識數(shù)活動的開始，比較適合于3歲左右的孩子。根據他們年齡小、好玩、好游戲、有意注意時間短的身心特點，我設計了認知活動“1”和“許多”。只學習“1”和“許多”相對低年齡段孩子而言較抽象和枯燥。但伴隨著游戲活動，就會讓幼兒在玩中學，在學中玩．既可以滿足幼兒游戲和好動的需要，又能很好地完成數(shù)學教育目標。根據這一指導思想，我選擇了“小兔采蘑菇”作為小班幼兒學習區(qū)別“1”和“許多”的教材，并幫助他們初步理解“l(fā)”和“許多”之間的關系。在整個教材中所涉及的動物形象“小白兔”，孩子們很熟悉，而且其中的活動簡單。比較形象直觀，滿足幼兒思維具體形象的特性，讓幼兒在游戲中建立初淺的數(shù)概念。
人教A版高中數(shù)學必修二簡單隨機抽樣教學設計
知識探究（一）：普查與抽查像人口普查這樣，對每一個調查調查對象都進行調查的方法，稱為全面調查（又稱普查）。 在一個調查中，我們把調查對象的全體稱為總體，組成總體的每一個調查對象稱為個體。為了強調調查目的，也可以把調查對象的某些指標的全體作為總體，每一個調查對象的相應指標作為個體。問題二：除了普查，還有其他的調查方法嗎？由于人口普查需要花費巨大的財力、物力，因而不宜經常進行。為了及時掌握全國人口變動狀況，我國每年還會進行一次人口變動情況的調查，根據抽取的居民情況來推斷總體的人口變動情況。像這樣，根據一定目的，從總體中抽取一部分個體進行調查，并以此為依據對總體的情況作出估計和判斷的方法，稱為抽樣調查（或稱抽查）。我們把從總體中抽取的那部分個體稱為樣本，樣本中包含的個體數(shù)稱為樣本量。
第二周國旗下講話稿：新學期 新征程
第二周國旗下講話稿：新學期新征程新的學期開始了，我們又踏上了前進的征程，無論前途是多么艱難，只要我xx一中人滿懷激情與夢想，就一定會有更完美的收獲，相信在16年的聯(lián)考與高考上，我們還會更上層樓。站在國旗下，我的心久久不能平靜，我在思考，一中給老師同學們的是什么？是這浮滿塵土的操場，是那簡陋的宿舍，還是那冬天都下雨的辦公室？都不是，xx一中給大家的是永不服輸?shù)挠職?，不怕艱難困苦的決心，是敢于亮劍，勇于負責的霸氣，相信在困苦的磨練下的一中人，越來越強，越來越棒！老師們，優(yōu)秀的教師一輩子都在備課，我校雖然在集智備課上快人一步，領先于其他學校，但也要認識到不足之處，深入研究，在方法與積累上多下功夫，穩(wěn)穩(wěn)抓住課堂這一中心，創(chuàng)新拼搏。“天道酬勤”“苦心人天不負”，相信有你們的辛苦奉獻，xx一中明天會更好！新學期讓我由衷的代表學校說一句“親愛的老師，您辛苦了”。有一句話說得好，“做最好的自己，才能碰撞出最好的別人”希望我們每位老師無論是在家庭還是學校里，始終用最好的自己去感染你的親人和學生，樂觀向上，幸福健康。
XX-XX學年開學第二周國旗下講話稿
開學第二周國旗講話發(fā)言稿 老師們，同學們：大家好！今天我國旗下演講的題目是《演好自己的角色》。每段時期自己都有屬于自己的角色，天真無邪的童年，懵懵懂懂的少年，輕狂迷茫的青年?？赡芎芏鄷r候你會懷念自己以前的角色，或者想象自己未來的角色，但最重要的是演好你自己現(xiàn)在的角色。因為你只有在自己的角色里才真正有發(fā)言權。信念要先行行勝于言，但是在行動之前給自己樹立好的心態(tài)更能起到事半功倍的效果。調整自己，這是不論干什么都要一直進行的一個過程。給自己正確積極的定位，要考慮到外界因素，但也不要被外界環(huán)境壓倒。學會選擇，學會放棄，學會承認自己的弱點，接下來我們就可以在更堅實更廣闊的道路上奔跑?！拔覀儾荒茏笥姨鞖?，但可以改變心情；我們不能選擇容貌，但可以展示笑容；我們不能預知明天，但可以把握今天?！?/p>
人教版高中歷史必修2二戰(zhàn)后蘇聯(lián)的經濟改革教案
⑤強調對外關系的靈活性。戈爾巴喬夫指出在對外政策中要采取多種辦法選擇不同的策略路線達到既定目標。在外交談判中不要為自己制造死胡同，也不要給對方制造死胡同，要善于迎合伙伴，尋求接觸點。在這種思想指導下，蘇共采取的對外戰(zhàn)略是以軍控為中心的緩和戰(zhàn)略，具體政策是繼續(xù)與美國就裁軍、消減核武器、限制地區(qū)沖突等問題進行談判，緩解蘇美關系；對西歐爭取建立“全歐大廈”；對東歐實行糾偏、不干涉政策；對中國改善關系，實現(xiàn)關系正常化；調整與第三世界國家關系，解決阿富汗、柬埔寨等問題。 3、影響：①經濟改革措施倉促上馬，缺少宏觀決策和相應的配套措施；加上戈爾巴喬夫沒有放棄蘇聯(lián)的傳統(tǒng)做法，繼續(xù)優(yōu)先發(fā)展重工業(yè)，致使改革未達到預期的效果，蘇聯(lián)經濟持續(xù)下滑②經濟體制改革受挫后，把改革的重點轉向政治領域，最終導致國內局勢的失控和蘇聯(lián)的解體。

人教版高中地理必修1第五章第二節(jié)自然地理環(huán)境的差異性教案
【補充說明】我們這節(jié)課簡要地分析了陸地環(huán)境的三種地域分異規(guī)律。實際上，世界上的任何事物有其一般性，也有它的特 殊性。在地帶性分異規(guī)律的基礎上，陸地環(huán)境因為受到海陸分布、地形 起伏等因素的影響，也會出現(xiàn)一些不規(guī)律的現(xiàn)象，這種現(xiàn)象稱為非地帶性。例如，我們在初中地理中學過綠洲。還記得什么叫綠洲嗎？再比如，在南美洲的西海岸（太平洋沿岸），有一條狹長的（熱帶）荒漠帶，而缺少熱帶草原帶，熱帶雨林帶主要是分布在赤道以北地區(qū)。這主要是受大的地形起伏的影響。因為南美洲西部是一列高大的安第斯山脈，受其影響，兩邊的氣候狀況不同，所以就出現(xiàn)了分布規(guī)律不同的自然帶，這也是一種非地帶性現(xiàn)象。【總結】有規(guī)律分布的自然帶構成了全球和諧的自然環(huán)境整體。自然帶之間錯綜復雜的、微妙的要素關系，有許多是人類還沒有認識到的。因此，人類不能隨意去破壞任何哪怕是極微小的環(huán)節(jié)，也許它 帶來的影響會是全球性的。保護全球環(huán)境，人人有責。
