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.

5、歸納小結(jié)，當(dāng)堂演練（10分鐘）1、肉食動物不可能是一條食物鏈中的第幾營養(yǎng)級（）A．第五B．第二C．第三D．第四2、對水稻→鼠→蛇→鷹這條食物鏈的錯誤描述是（）A.水稻是生產(chǎn)者B.鼠是初級消費者C.蛇是次級消費者D.鷹屬于第三營養(yǎng)級3、在下列生物中，屬于分解的是（）A.藍藻B.草履蟲C.蘑菇D.蝗蟲4、從生態(tài)系統(tǒng)的組成成分看，硝化細菌和蚯蚓屬于（）A.生產(chǎn)者和分解者B.生產(chǎn)者和消費者C.消費者和分解者D.分解者和消費者5、下列哪組生物可和無機環(huán)境組成一個生態(tài)系統(tǒng)（）A．水藻、鳥B．小魚、大魚C．小草、昆蟲、細菌D．水藻、蝦6、對草→昆蟲→食蟲鳥→鷹這條食物鏈的敘述,正確的是（）A．有四個營養(yǎng)級，兩個次級消費者B．有三個營養(yǎng)級，一個生產(chǎn)者C．食蟲鳥是第三營養(yǎng)級、次級消費者D．有三個營養(yǎng)級，三個消費者（設(shè)計意圖）進行簡單扼要的課堂小結(jié)與練習(xí)，可以把課堂傳授的知識盡快地轉(zhuǎn)化為學(xué)生的素質(zhì)；也可使學(xué)生更深刻地理解理論在實際生活中的應(yīng)用。
人教版高中生物必修3第三章第二節(jié)《生長素的生理作用》說課稿
強調(diào)重力對生長素分布的影響，為下面的內(nèi)容講解做鋪墊，明確植物出現(xiàn)向光性與生長素分布不均有關(guān)。復(fù)習(xí)舊知識，產(chǎn)生首因效應(yīng)，鞏固和加強記憶。通過植物向光性是生長素分布較多而促進生長，進而提出“對于植物來說，生長素是不是越多越好”這個問題，引發(fā)思考，鍛煉思維。說明生長素濃度對不同器官產(chǎn)生的影響不同，讓學(xué)生對這一情況有一個整體印象。結(jié)合數(shù)學(xué)知識逐步分析圖上各點和各曲線的含義，引導(dǎo)學(xué)生得出不同器官對生長素濃度的敏感性順序，為解釋橫放植物“S”型生長做鋪墊。通過對曲線的分析，得出低生長素濃度起促進作用，高濃度有抑制作用這種雙重性，并得出其雙重性表現(xiàn)。通過以上的分析和總結(jié)，對橫放植物“S”型生長進行解釋，達到首尾呼應(yīng)的效果。采用“蒙太奇”手法，引申到“太空中，橫放植物將會如何生長”這個問題，引發(fā)學(xué)生的聯(lián)想和思考，以這種提問方式結(jié)課為下節(jié)課的開課做了鋪墊，掌握了主動權(quán)。
人教版高中生物必修3第二章第四節(jié)《免疫調(diào)節(jié)》說課稿
（四）、活動交流，體驗科學(xué)通過資料分析討論以下三個問題：1、你知道愛滋病的傳播途徑嗎？2、如何預(yù)防愛滋?。?、我們應(yīng)如何對待愛滋病患者？面對艾滋病我們能做些什么？從而進入情感態(tài)度的教育。除此之外，我還設(shè)計一個開放性的作業(yè)“向全社會為關(guān)注艾滋病設(shè)計一個宣傳廣告”（形式不限，漫畫、板書、倡議書等），讓學(xué)生把愛心付諸于實際行動。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、器官移植三個方面講述，讓學(xué)生充分體驗到知識和社會生活的緊密聯(lián)系，讓他們不在感到科學(xué)是那么的遙遠，而是可愛的有用的。通過交流，讓同學(xué)們體會到合作的魅力和重要性，進一步培養(yǎng)合作意識和合作能力。最后我設(shè)計一個資料搜集，讓同學(xué)們選一個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？開展世界艾滋病運動有什么意義？

（5）根據(jù)實驗的第五部分——驗證性實驗結(jié)果，證實了達爾文關(guān)于植物向光性運動原因的假說――確實存在一種物質(zhì)致使胚芽尖端產(chǎn)生了向光運動。這樣通過多個實驗的多媒體演示過程，強化學(xué)生的思維，最終在學(xué)生的大腦中形成科學(xué)研究過程的”條件反射”。為了使學(xué)生初步學(xué)會”設(shè)計對照實驗的方法”，首先也利用多媒體的演示實驗，并在其中特意設(shè)置一些”陷阱”，通過多次”請學(xué)生進入‘陷阱’”，來強化設(shè)計實驗時應(yīng)該控制的變量問題，從而在學(xué)生的認(rèn)知領(lǐng)域里初步構(gòu)建出設(shè)計對照實驗的知識體系。3、歸納總結(jié)1934年，荷蘭科學(xué)家郭葛等人從植物中分離出了這種能使植物產(chǎn)生向光性的物質(zhì)，并確定它就是吲哚乙酸。這就真正從化學(xué)物質(zhì)的角度證實了達爾文的假設(shè)。在能夠從植物體中分離提取出生長素之后，要想知道：除了能使植物產(chǎn)生向光運動之外，生長素對于植物的器官還有什么作用？可以采用哪種方法來進行試驗？
