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.

教學(xué)過(guò)程:(一)導(dǎo)入:課前放《愛(ài)的奉獻(xiàn)》歌曲,同時(shí)不斷播放一些有關(guān)“愛(ài)”的主題的圖片,渲染一種情感氛圍。師說(shuō):同學(xué)們,誰(shuí)能說(shuō)說(shuō)這組圖片的主題應(yīng)該是什么?生(七嘴八舌):母愛(ài),不對(duì)是親情……是友情、還有人與人互相幫助……那組軍人圖片是說(shuō)保衛(wèi)國(guó)家,應(yīng)該是愛(ài)國(guó)……那徐本禹和感動(dòng)中國(guó)呢?…………生答:是關(guān)于愛(ài)的方面師說(shuō):不錯(cuò),是關(guān)于愛(ài)的方面。那么同學(xué)們,今天就以“愛(ài)的奉獻(xiàn)”為話(huà)題,來(lái)寫(xiě)一篇議論文如何?生答:老師,還是寫(xiě)記敘文吧。生答:就是,要不議論文寫(xiě)出來(lái)也象記敘文。師問(wèn):為什么?生答:老師,這個(gè)話(huà)題太有話(huà)說(shuō)了,一舉例子就收不住了,怎么看怎么象記敘文。生答:就是,再用一點(diǎn)形容詞,就更象了。眾人樂(lè)。師說(shuō):那么同學(xué)們誰(shuí)能告訴我,為什么會(huì)出現(xiàn)這種問(wèn)題?一生小聲說(shuō):還不是我們笨,不會(huì)寫(xiě)。師說(shuō):不是笨,也不是不會(huì)寫(xiě),你們想為什么記敘文就會(huì)寫(xiě),一到議論文就不會(huì)了,那是因?yàn)橥瑢W(xué)們沒(méi)有明白議論文中的記敘與記敘文中的記敘有什么不同,所以一寫(xiě)起議論文中的記敘,還是按照記敘文的寫(xiě)法寫(xiě)作,這自然就不行了。那好,今天我們就從如何寫(xiě)議論文中的記敘講起。

3、評(píng):以評(píng)促行。(6分鐘)高中生的年齡特點(diǎn)決定了他們非常重視別人對(duì)自己的評(píng)價(jià),渴望得到他人的肯定與鼓勵(lì)。(所以我在班上組織一個(gè)活動(dòng):讓同學(xué)們?cè)u(píng)選出班上“講文明懂禮貌的文明之星”、“勤思考善創(chuàng)新的學(xué)習(xí)之星”(先讓同學(xué)推舉大家都認(rèn)同的4位同學(xué),然后對(duì)他們進(jìn)行投票,投票結(jié)果將在下堂課上公布)以此活動(dòng)來(lái)激發(fā)同學(xué)們用實(shí)際行動(dòng)做民族精神的踐行者和傳播者。)4、唱:以情激行。(2分鐘)在課程內(nèi)容講授結(jié)完畢后,組織全班同學(xué)跟著音樂(lè)高唱孫楠的《紅旗飄飄》,生化情感,激發(fā)同學(xué)們的愛(ài)國(guó)情感。五、課堂拓展(請(qǐng)同學(xué)們各展才華:課后讓同學(xué)們各自準(zhǔn)備一個(gè)項(xiàng)目以體現(xiàn)民族精神。(項(xiàng)目形式是:或作文、書(shū)畫(huà);或剪紙、或歌曲小品)……讓同學(xué)們用實(shí)際行動(dòng)祝愿我們偉大的祖國(guó)更加繁榮昌盛!讓我們的民族精神代代相傳!)

板書(shū):多民族文化對(duì)中華文化的意義師:中華民族是多民族的共同體,中華文化呈現(xiàn)多種民族文化的豐富色彩。中華各民族的文化,既有中華文化的共性,又有各自的民族特性。它們都是中華文化的瑰寶,都是中華民族的驕傲。各兄弟民族文化相互交融、相互促進(jìn),共同創(chuàng)造了中華文化。各族人民對(duì)共同擁有的中華文化的認(rèn)同感和歸屬感,顯示了中華民族厚重的文化底蘊(yùn)和強(qiáng)大的民族凝聚力。問(wèn)題探究8溫家寶總理在美國(guó)會(huì)見(jiàn)華僑時(shí)滿(mǎn)懷深情地說(shuō),中國(guó)已解決了香港問(wèn)題和澳門(mén)問(wèn)題,洗刷了百年恥辱,現(xiàn)在剩下一個(gè)臺(tái)灣問(wèn)題,“這一灣淺淺的海峽是我們最大的鄉(xiāng)愁、最大的國(guó)殤”。用有關(guān)知識(shí)分析:為什么“這一灣淺淺的海峽是我們最大的鄉(xiāng)愁、最大的國(guó)殤”?生1:臺(tái)灣是中國(guó)的一部分,臺(tái)灣各族人民是中華民族的一部分,臺(tái)灣文化歸屬于中華文化。生2:傳統(tǒng)的民族文化是維系民族生存和發(fā)展的精神紐帶。

環(huán)節(jié)三:多媒體繼續(xù)展示石窟藝術(shù)、民族文學(xué)等,學(xué)生在感受少數(shù)民族文化成就的過(guò)程中不難得出結(jié)論:各民族文化都為中華文化作出了重要貢獻(xiàn),都是中華民族的驕傲。由此進(jìn)入第三目“中華之瑰寶,民族之驕傲”。各族人民對(duì)中華文化的認(rèn)同感和歸屬感,顯示了中華民族厚重的文化底蘊(yùn)和強(qiáng)大的民族凝聚力。環(huán)節(jié)四:合作探究中華文化博大精深的原因。學(xué)生調(diào)動(dòng)已有歷史知識(shí)儲(chǔ)備和課前搜集的材料分組交流:歷史上在思想文化方面,對(duì)諸家學(xué)說(shuō)所采取的兼收并蓄的學(xué)術(shù)主張;中國(guó)文化長(zhǎng)期吸收周邊少數(shù)民族的哪些優(yōu)秀文明;在對(duì)待外域文化上,中華民族是否敞開(kāi)博大胸懷揚(yáng)棄吸收。2、從現(xiàn)代找出能充分體現(xiàn)中華民族的文化開(kāi)放心態(tài)和中華文化非凡融合力的例子。這樣可增添幾分時(shí)代氣息,更好地服務(wù)于當(dāng)下實(shí)踐。

2、學(xué)生分析 九十年代初期出生的孩子,生活在一個(gè)充滿(mǎn)活力的時(shí)代,張揚(yáng)個(gè)性成為他(她)們的主旋律。面對(duì)這一時(shí)代的學(xué)生,溝通需要用心、用技巧,那也是一門(mén)藝術(shù)。高中學(xué)生的心理日趨成熟,有一定的知識(shí)積累,且比較豐富;語(yǔ)言邏輯性強(qiáng),有較強(qiáng)的參與意識(shí),求知欲望及表現(xiàn)欲望。學(xué)生主體參與的充分,表現(xiàn)在其主動(dòng)性,積極性得到極大的調(diào)動(dòng)。這與教師的主導(dǎo)作用是分不開(kāi)的。本課教案就是要引導(dǎo)學(xué)生自己先閱讀書(shū)本、獨(dú)立思考、激發(fā)學(xué)生思維,引導(dǎo)學(xué)生各抒己見(jiàn),讓學(xué)生自己得出解答問(wèn)題的結(jié)論,不追求答案的唯一。充分體現(xiàn)了讀書(shū)是一種個(gè)體行為,每個(gè)學(xué)生有不同的體驗(yàn)。教師應(yīng)跳出教案的問(wèn)題模式,和學(xué)生一道去創(chuàng)造地發(fā)現(xiàn)問(wèn)題、分析問(wèn)題、解決問(wèn)題,在成功中尋找快樂(lè)、在快樂(lè)中更加成功。同時(shí)特別注重創(chuàng)設(shè)的情景的選擇性,有針對(duì)性和實(shí)效性,引導(dǎo)學(xué)生們積極、主動(dòng)參與,使他們的潛能、智慧得出充分挖掘、展示。只有當(dāng)學(xué)生們?cè)谡n堂上表現(xiàn)出來(lái)的獨(dú)特的、有創(chuàng)意的設(shè)計(jì)見(jiàn)解,學(xué)生主體參與和教師主導(dǎo)二者完美結(jié)合,才能表明該課的設(shè)計(jì)卓有成效。

師:同學(xué)們這個(gè)暑假過(guò)得真不錯(cuò)呀,都有自己最開(kāi)心的日子。同學(xué)們經(jīng)歷的這些活動(dòng),讓你們自己長(zhǎng)了知識(shí),豐富了閱歷,你們今天的介紹,也讓我和更多的同學(xué)大開(kāi)了眼界。由此可見(jiàn),在今天,通過(guò)親身參與、實(shí)踐,通過(guò)網(wǎng)絡(luò)、電影,通過(guò)交流發(fā)言,大家獲得了許多新的信息、知識(shí),增強(qiáng)了對(duì)祖國(guó)美好河山的熱愛(ài)、對(duì)科技的向往和異國(guó)的友誼。同學(xué)們信息交流的過(guò)程,實(shí)際上也是文化傳播的過(guò)程。板書(shū)課題:第二課時(shí)文化在交流中傳播話(huà)題導(dǎo)入討論話(huà)題:如何建設(shè)文明校園?(課前準(zhǔn)備:要求同學(xué)們仔細(xì)觀(guān)察、了解關(guān)于校園文明現(xiàn)象的問(wèn)題,并就如何建設(shè)文明校園提出自己的建議。教師可按自然組,讓學(xué)生推選一名代表發(fā)言,就校園文明方面談?wù)劥嬖诘膯?wèn)題和不足,或提出一些中肯的改進(jìn)意見(jiàn))(學(xué)生交流)生1:建設(shè)文明校園,首先要凈化語(yǔ)言環(huán)境,我們學(xué)校不少同學(xué)愛(ài)說(shuō)臟話(huà),與文明校園很不相稱(chēng)。

一、教材分析文化市場(chǎng)和大眾傳媒的發(fā)展,給我們的文化生活帶來(lái)了許多可喜的變化。但是,文化市場(chǎng)的自發(fā)性和傳媒的商業(yè)性也引發(fā)了令人憂(yōu)慮的現(xiàn)象。文化生活有“喜”也有“憂(yōu)”,讓我們歡喜讓我們憂(yōu)。面對(duì)形式多樣的文化生活,置身于文化生活的海洋之中,在文化生活中如何選擇、怎樣作出正確的選擇是亟待向?qū)W生解決的問(wèn)題。二、學(xué)情分析高二學(xué)生處于世界觀(guān)、人生觀(guān)和價(jià)值觀(guān)形成的關(guān)鍵時(shí)期,身心迅速發(fā)展,自我意識(shí)和獨(dú)立性較強(qiáng),社會(huì)公共生活空間范圍越來(lái)越大,并且開(kāi)始理性地思考社會(huì)和人生的重大問(wèn)題,他們可塑性強(qiáng),但情緒仍然不穩(wěn)定,有多變性,容易沖動(dòng)或偏激,迫切需要提升思想意識(shí),加強(qiáng)方法論的指導(dǎo),使其在紛繁復(fù)雜的文化生活中能夠進(jìn)行正確的判斷與選擇。如果我們的學(xué)生不能把握正確的航向,是非觀(guān)念模糊,良莠不分,就會(huì)陷入落后文化和腐朽文化的泥沼而不能自拔,甚至造成無(wú)法挽回的惡果。

(4)自強(qiáng)不息 (引導(dǎo)學(xué)生簡(jiǎn)要了解介紹 “大禹治水”“ 愚公移山”“ 夸父追日”“ 富貴不能淫”等典故名言,注重從優(yōu)秀傳統(tǒng)文化和中華民族精神之間的關(guān)系角度總結(jié)。)三、永遠(yuǎn)高揚(yáng)的愛(ài)國(guó)主義旗幟這一目講述中華民族精神的核心,新時(shí)期愛(ài)國(guó)主義的主題?!咎骄咳浚?、團(tuán)結(jié)統(tǒng)一、愛(ài)好和平、勤勞勇敢、自強(qiáng)不息共同體現(xiàn)著一個(gè)什么主題?2、你知道哪些我國(guó)抒發(fā)愛(ài)國(guó)情懷的詩(shī)詞格言警句?哪些歷史故事或者你身邊的事例體現(xiàn)出了愛(ài)國(guó)主義的精神追求?你認(rèn)為新時(shí)期我國(guó)愛(ài)國(guó)主義主要體現(xiàn)在哪些方面?學(xué)生四人一個(gè)小組討論,選派代表發(fā)言【師生總結(jié)】:1、愛(ài)國(guó)主義是中華民族精神的核心,是中華民族的精神支柱。2、新時(shí)期愛(ài)國(guó)主義的主題:愛(ài)國(guó)主義是具體的,不同時(shí)期有不同的內(nèi)涵,新時(shí)期愛(ài)國(guó)與愛(ài)社會(huì)主義本質(zhì)上是一致的,發(fā)展中國(guó)特色社會(huì)主義,擁護(hù)祖國(guó)統(tǒng)一是新時(shí)期愛(ài)國(guó)主義的主題。

談到這,如果有人會(huì)說(shuō)這僅僅是在于我個(gè)人與戰(zhàn)場(chǎng)之上,戰(zhàn)場(chǎng)之下另當(dāng)別論,那么,他完全錯(cuò)了。在我小學(xué)四年級(jí)的語(yǔ)文課上有兩個(gè)人發(fā)言積極,一個(gè)姓黃,一個(gè)姓康,黃同學(xué)發(fā)言比康同學(xué)更積極,班上的同學(xué)常以為黃同學(xué)是個(gè)了不得的人物,后來(lái),教語(yǔ)文的吳老師曾悄悄地告訴我:班上真正厲害的是康x,那黃x沒(méi)什么,說(shuō)的全是“一點(diǎn)通”上的,照搬不誤。說(shuō)到這,我還得厚著臉皮自夸一下,在四年級(jí)時(shí),我和康同學(xué)是同坐,一次,老師叫我們對(duì)一片課文(好象是寫(xiě)黃繼光舍身炸暗堡)的一個(gè)段落提問(wèn)題時(shí),我悄悄地對(duì)康同學(xué)說(shuō)了一個(gè)問(wèn)題,康同學(xué)對(duì)我說(shuō):“你站起來(lái)說(shuō)嘛?!眱?nèi)向的我遙遙頭,康同學(xué)便站舉手,并起來(lái)將我的問(wèn)題大聲地說(shuō)了出來(lái),結(jié)果老師說(shuō):“恩,康x的問(wèn)題提得很好?!?/p>

3、總結(jié)(這部分要5分鐘)學(xué)生在教師的提示和問(wèn)題的引導(dǎo)下,完成對(duì)本節(jié)課的知識(shí)的歸納和小結(jié)。利用簡(jiǎn)煉、清晰的語(yǔ)言,再一次的突出本節(jié)課的重點(diǎn),起到畫(huà)龍點(diǎn)睛的作用,培養(yǎng)了學(xué)生的表達(dá)能力。4、鞏固練習(xí)(這部分要10分鐘)用大屏幕投影把題目投影在屏幕上,讓學(xué)生思考,然后回答。這部分安排10分鐘的時(shí)間,讓學(xué)生思考完成具有針對(duì)性的練習(xí),進(jìn)行知識(shí)鞏固和教學(xué)效果反饋,及時(shí)糾正錯(cuò)誤的理解和片面的認(rèn)識(shí)。5、板書(shū)設(shè)計(jì)在板書(shū)中,我根據(jù)板書(shū)的“規(guī)范、工整和美觀(guān)”的要求,結(jié)合所學(xué)的內(nèi)容,設(shè)計(jì)了如圖所示的板書(shū)。在其中,注重了重、難點(diǎn)的突出,使學(xué)生對(duì)知識(shí)的結(jié)構(gòu)、層次、重點(diǎn)、難點(diǎn)一目了然,便于記憶和理解。四、效果分析對(duì)于反射的判斷,學(xué)生仍有可能出現(xiàn)錯(cuò)誤,如刺激坐骨神經(jīng)肌肉的收縮,教師應(yīng)強(qiáng)調(diào)沒(méi)有完整的反射弧結(jié)構(gòu)參與的不是反射。

二、應(yīng)用生長(zhǎng)調(diào)節(jié)劑的注意事項(xiàng)1、效果不穩(wěn)定。2、使用時(shí)期。3、使用濃度和方法。4、使用生長(zhǎng)調(diào)節(jié)劑僅是葡萄栽培管理的輔助手段,不能盲目孤立地依賴(lài)生長(zhǎng)調(diào)節(jié)劑。生2:我們小組查的資料是關(guān)于小麥?zhǔn)褂蒙L(zhǎng)調(diào)節(jié)劑。小麥應(yīng)用植物生長(zhǎng)調(diào)節(jié)劑,可以調(diào)節(jié)植株的生長(zhǎng)發(fā)育,具有控旺促壯、增強(qiáng)抗逆性、增加粒重、提高產(chǎn)量并有利于優(yōu)質(zhì)、早熟等多重效果。生3:我找了一篇生長(zhǎng)調(diào)節(jié)劑對(duì)矮牽牛大型穴盤(pán)生產(chǎn)。師:上面三位同學(xué)利用課下的時(shí)間,在網(wǎng)上查的三段文字都相當(dāng)?shù)牟诲e(cuò),大家可以從中學(xué)到一些書(shū)本上沒(méi)有的知識(shí),請(qǐng)大家結(jié)合剛剛?cè)煌瑢W(xué)的三段文字以及自己平時(shí)所積累的知識(shí),討論以下幾個(gè)問(wèn)題。師:你知道哪些農(nóng)產(chǎn)品在生產(chǎn)過(guò)程中使用了植物生長(zhǎng)調(diào)節(jié)劑?師:哪些水果在上市前有可能使用了乙烯利?師:生產(chǎn)過(guò)程中施用植物生長(zhǎng)調(diào)節(jié)劑,會(huì)不會(huì)影響農(nóng)產(chǎn)品的品質(zhì)?師:如果你是水果銷(xiāo)售員,面對(duì)半青不熟的水果,你認(rèn)為應(yīng)當(dāng)使用乙烯利催熟嗎?作為一個(gè)消費(fèi)者,你又怎么看?

(四)、活動(dòng)交流,體驗(yàn)科學(xué)通過(guò)資料分析討論以下三個(gè)問(wèn)題:1、你知道愛(ài)滋病的傳播途徑嗎?2、如何預(yù)防愛(ài)滋???3、我們應(yīng)如何對(duì)待愛(ài)滋病患者?面對(duì)艾滋病我們能做些什么?從而進(jìn)入情感態(tài)度的教育。除此之外,我還設(shè)計(jì)一個(gè)開(kāi)放性的作業(yè)“向全社會(huì)為關(guān)注艾滋病設(shè)計(jì)一個(gè)宣傳廣告”(形式不限,漫畫(huà)、板書(shū)、倡議書(shū)等),讓學(xué)生把愛(ài)心付諸于實(shí)際行動(dòng)。在此基礎(chǔ)上引出“免疫學(xué)的應(yīng)用”從免疫預(yù)防、免疫治療、器官移植三個(gè)方面講述,讓學(xué)生充分體驗(yàn)到知識(shí)和社會(huì)生活的緊密聯(lián)系,讓他們不在感到科學(xué)是那么的遙遠(yuǎn),而是可愛(ài)的有用的。通過(guò)交流,讓同學(xué)們體會(huì)到合作的魅力和重要性,進(jìn)一步培養(yǎng)合作意識(shí)和合作能力。最后我設(shè)計(jì)一個(gè)資料搜集,讓同學(xué)們選一個(gè)感興趣的主題利用電腦在網(wǎng)上搜集有關(guān)資料。主題:1、你知道世界艾滋病日嗎?歷年的主題是什么?開(kāi)展世界艾滋病運(yùn)動(dòng)有什么意義?
