Example:One day, a poor boy who was trying to pay his way through school by sending newspapers door to door found that he only had one dime(一角）left. He was so hungry that he decided to beg for a meal at the next house.However, he lost his nerve when a lovely young woman opened the door. Instead of a meal he asked for a drink of water. She thought he looked hungry so she brought him a large glass of milk. He drank it slowly, and then asked, “How much do I owe you?” “You don’t owe me anything,” she replied, “Mother has taught me never to accept pay for a kindness.” “Then I thank you from the bottom of my heart.” With these words, Howard Kelly left that house.Years later the woman became badly ill and was finally sent to the hospital in a big city. Dr. Howard Kelly, now famous, was called in. When he heard the name of the town she came from, a strange light filled his eyes. Dressed in his doctor’s clothes, Dr. Kelly went into her room and recognized her at once. From that day on, he gave special attention to her, and decided to do his best to save her life.At last the woman was saved. Dr. Kelly asked the business office to pass the final bill to him. He looked at it and then wrote something on the side. The bill was sent to the woman’s room. She was afraid to open it because she was sure that it would take the rest of her life to pay for it off. Finally she looked, and the note on the side of the bill caught her attention. She read these words: “Paid in full with a glass of milk, Dr. Howard Kelly.” Tear of joy flooded her eyes.

Everybody wants to get wealth.In today’s material world,making money or becoming wealthy symbolizes a person’s success and capability. Many people just make every effort, pay any price to attain greater wealth. With money,they can buy nice, large apartments in nice neighborhood. With money they can own luxurious cars. Wealth seems to bring all happiness in life.But is wealth the only road to happiness? Not really. There are many things in the world, which are beyond the means of money, such as friendship, love, health and knowledge. People are so preoccupied with struggling for money that they have no time or would not take the time to form or maintain friendship. What happiness can they feel living as lonely miserable creatures without love or friends in the world even if they accumulate tremendous wealth?In my opinion, people can’t do anything without money, but money is not everything. What money will bring you depends on your personal belief and goal in life. If you are kind enough to help others, especially the poor, money is a good thing to you. With it, you can do much more for the benefit of people and your country, and it will add to your own happiness. If you want money just for your own needs, you’ll never be satisfied or happy. In a word,you should have money spent for more people. Only then can money be the source of your happiness.Step 8 Homework4 students in a group, one acts Roderick, one Oliver, one servant and the fourth one acts Henry Adams, then listen to the tape, pay more attention to the difference between American English and British English in pronunciation, stress, tone.

春季期第二學(xué)期4月份國旗下講話
主題 緬懷先烈，繼承遺志尊敬的老師，親愛的同學(xué)們：早上好！這個星期三就是清明節(jié)了，很多人都要回家祭祖掃墓了。“清明時節(jié)雨紛紛，路上行人欲斷魂.”說的就是每當(dāng)這個特殊的時候，人們都會倍加思念已經(jīng)死去的親人，心情難免傷感。今天在這莊嚴(yán)的升旗儀式上，我們凝視著烈士鮮血所染的國旗，不覺思緒又回到那艱苦崢嶸的歲月：舊中國飽受戰(zhàn)爭的創(chuàng)傷和帝國主義的欺凌，人民受盡磨難和屈辱。舊上海的公園門口曾立著一塊醒目的牌子，上面寫著“華人與狗不得入內(nèi)。”外國輪船在黃浦江上肆意闖蕩，撞翻中國民船，淹死中國人也不管。那時洋人在中國土地上為所欲為，國人已喪失了最起碼的做人尊嚴(yán)。祖國危難之時，無數(shù)愛國志士挺身而出，為了祖國的獨立統(tǒng)一和人民的解放，甘灑一腔熱血。從不惜千金買寶刀，貂裘換酒也堪豪的女俠秋瑾，到一腔熱血勤珍重，灑去猶能化碧濤的鄒容；從江姐到劉胡蘭；從黃繼光到董存瑞……無數(shù)英烈用他們的生命，譜寫了一曲曲壯烈的愛國樂章。難道他們不知道生命的可貴嗎？不！他們非常珍惜自己的生命，但是他們深深懂得：在祖國危亡之時，作為一個中國人，保衛(wèi)祖國，拯救祖國是自己的責(zé)任，為了祖國的解放，先烈們拋頭顱灑熱血，戰(zhàn)火中出生入死，監(jiān)牢里堅貞不屈，刑場上大義凜然。他們用生命、熱血換來了華夏民族的新生。
XX年春季期第二學(xué)期3月份國旗下講話
主題 學(xué)習(xí)雷鋒好榜樣尊敬的老師、親愛的同學(xué)們，大家好！963年3月5日，毛澤東同志發(fā)出了“向雷鋒同志學(xué)習(xí)”的號召。40多年來，雷鋒成為我們社會真情與愛心的化身，成為中國人民可貴的精神財富；雷鋒精神刻在人們的靈魂深處，引領(lǐng)著一代又一代人健康成長。同學(xué)們，雷鋒這個名字你一定不會陌生，但你可知道，什么是雷鋒精神？第一，奉獻社會。一個人做一件好事并不難，難的是一輩子做好事。雷鋒堅持一輩子做好事，一輩子為人民服務(wù)，在他身上體現(xiàn)的是一種強烈的社會責(zé)任感。一次雷鋒外出，在沈陽站換車的時候，發(fā)現(xiàn)一個背著小孩的中年婦女車票和錢丟了，就買了一張火車票塞到大嫂手里。大嫂含著眼淚問：“大兄弟，你叫什么名字，是哪個單位的？”雷鋒說：“我叫解放軍，就住在中國?！薄袄卒h出差一千里，好事做了一火車”。弘揚雷鋒精神，就是要像雷鋒那樣，把社會責(zé)任感和使命感記在心間，隨時隨地為祖國和人民貢獻自己的智慧和力量。第二，刻苦學(xué)習(xí)。雷鋒不僅是奉獻的楷模，還是學(xué)習(xí)成才的典范。他干一行愛一行，干一行專一行，擠出一切可以擠出的時間，努力學(xué)習(xí)為人民服務(wù)的本領(lǐng)。雷鋒參軍后不久，被分到運輸連當(dāng)汽車兵,他就把書本裝在挎包里,只要車一停,他就坐在駕駛室里看書。他在日記中寫道:“要學(xué)習(xí)，時間總是有的,問題是我們善不善于擠,愿不愿意鉆。一塊好好的木板,上面一個眼也沒有,但釘子為什么能鉆進去呢?我們在學(xué)習(xí)上也要提倡這種釘子精神,善于擠和鉆?！?/p>

《以工匠精神雕琢?xí)r代品質(zhì)》說課稿 2022-2023學(xué)年統(tǒng)編版高中語文必修上冊
答案：銅車馬的輝煌,來自原料的精挑細選、工藝的精巧極致和工匠的精心雕琢。可以說,是精益求精的工匠精神鍛造出了“青銅之冠”的銅車馬。2.“工匠精神”如此重要，那么，你認為“工匠精神”有著怎樣的現(xiàn)實意義?觀點一:工匠精神在企業(yè)層面，可以認為是企業(yè)精神。具體而言，表現(xiàn)在以下幾個方面。第一，創(chuàng)新是企業(yè)不斷發(fā)展的精神內(nèi)核。第二，敬業(yè)是企業(yè)領(lǐng)導(dǎo)者精神的動力。第三，執(zhí)著是企業(yè)走得長久的底氣。改革開放40 多年來，我國涌現(xiàn)出大批有工匠精神的企業(yè)，但也有一些企業(yè)缺乏企業(yè)精神，只追求“短平快”的經(jīng)濟效益。這正是經(jīng)濟發(fā)展的隱憂所在。觀點二:工匠精神在員工層面，就是一-種認真精神、敬業(yè)精神。其核心是: 不僅僅把工作當(dāng)作賺錢養(yǎng)家糊口的工具，而是樹立起對職業(yè)敬畏、對工作執(zhí)著、對產(chǎn)品負責(zé)的態(tài)度，極度注重細節(jié)，不斷追求完美和極致，給客戶無可挑剔的體驗。我國制造業(yè)存在大而不強、產(chǎn)品檔次整體不高、自主創(chuàng)新能力較弱等現(xiàn)象，多少與工匠精神稀缺、“差不多精神”有關(guān)。
