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.

3、遺傳密碼的特點(diǎn) 連續(xù)性、簡(jiǎn)并性、通用性5、課堂練習(xí)6、作業(yè)布置假如，我們利用(ACU)n核苷酸長(zhǎng)鏈合成了含有蘇氨酸的多肽，那么蘇氨酸可能的密碼子有哪些？如何運(yùn)用實(shí)驗(yàn)方法確證蘇氨酸的密碼子究竟是什么？七、教學(xué)反思1、教材中豐富的科學(xué)史料，是我們?cè)谡n堂上進(jìn)行探究性學(xué)習(xí)活動(dòng)的良好素材，教師要整理和運(yùn)用好。千萬不要低估學(xué)生的思維能力，當(dāng)學(xué)生的思維能力被你想方設(shè)法激發(fā)出來的時(shí)候，你會(huì)發(fā)現(xiàn)他們的創(chuàng)造力是無窮的。2、探究性學(xué)習(xí)的目的并不僅僅是問題的解決，更重要的是在探究過程中體驗(yàn)和獲取科學(xué)研究方法，培養(yǎng)合作與分享的精神以及實(shí)事求是的科學(xué)態(tài)度，鍛煉思維能力，提高科學(xué)素養(yǎng)。3、學(xué)生是學(xué)習(xí)的主體，教師是引導(dǎo)者。我們要采取措施讓學(xué)生積極主動(dòng)地參與到學(xué)習(xí)活動(dòng)中來，通過他們的思考、討論、爭(zhēng)辯、合作等活動(dòng)來獲取方法，建構(gòu)知識(shí)。
人教版高中生物必修2染色體變異說課稿
四、說教學(xué)程序（一）.溫故知新、導(dǎo)入新課復(fù)習(xí)提問:基因突變導(dǎo)致生物變異的原因是什么?回答:基因突變是基因結(jié)構(gòu)發(fā)生改變，從而使遺傳信息改變，使蛋白質(zhì)結(jié)構(gòu)改變、生物性狀改變，即生物發(fā)生了變異。那么，基因是什么?它和染色體又有何關(guān)系?回答:基因是有遺傳效應(yīng)的DNA片斷，染色體是DNA的載體，基因在染色體上呈線形排列。引出新知:對(duì)于一個(gè)生物體來說，正常情況下，其染色體的結(jié)構(gòu)和數(shù)量都是穩(wěn)定的。但在自然條件或人為因素的影響下，染色體的結(jié)構(gòu)和數(shù)量均會(huì)發(fā)生改變，從而導(dǎo)致生物性狀的改變，這就屬于染色體變異。（二）.把握重點(diǎn)、突破難點(diǎn)重點(diǎn)的把握：1、染色體結(jié)構(gòu)的變異播放影片:貓叫綜合征幼兒。讓學(xué)生觀察: 患兒哭聲輕、音調(diào)高，很像貓叫。教師補(bǔ)充: 患兒的征狀---兩眼較低、耳位低下，存在著嚴(yán)重的智力障礙。闡述病因---染色體片段缺失

回歸生活：近幾年,我國(guó)市場(chǎng)上豬肉價(jià)格在不斷地波動(dòng)。請(qǐng)智囊團(tuán)商議：我們集團(tuán)如何才能避免重蹈“張老漢”的覆轍？學(xué)生活動(dòng)：思考、發(fā)言、群策群力。教師鼓勵(lì)學(xué)生從多角度分析，找出解決問題的不同方法。教師點(diǎn)撥：在豬肉價(jià)格波動(dòng)較大時(shí)，我們除了調(diào)節(jié)生產(chǎn)規(guī)模，還可以采用引進(jìn)新品種、加強(qiáng)科學(xué)管理等手段來提高勞動(dòng)生產(chǎn)率，從而在價(jià)格競(jìng)爭(zhēng)中更具優(yōu)勢(shì)。同時(shí)，我們要在激烈的市場(chǎng)競(jìng)爭(zhēng)中站穩(wěn)腳跟，還必須以市場(chǎng)為導(dǎo)向，生產(chǎn)適銷對(duì)路的高質(zhì)量產(chǎn)品，做到“人無我有，人有我優(yōu)，人優(yōu)我轉(zhuǎn)”。教師引導(dǎo)學(xué)生分析：價(jià)格變動(dòng)對(duì)生產(chǎn)規(guī)模的調(diào)節(jié)、對(duì)勞動(dòng)生產(chǎn)率的提高及促使企業(yè)生產(chǎn)適銷對(duì)路的高質(zhì)量產(chǎn)品，就是在價(jià)格、供求關(guān)系及市場(chǎng)競(jìng)爭(zhēng)的刺激下，價(jià)值規(guī)律發(fā)揮“棒子”（調(diào)節(jié)資源配置）、“鞭子”（鞭策個(gè)別勞動(dòng)生產(chǎn)率的提高）及“篩子”（優(yōu)勝劣汰）作用的結(jié)果，從而將本節(jié)課的內(nèi)容與第一框題有機(jī)聯(lián)系在一起，幫助學(xué)生從不同角度更深刻的理解價(jià)值規(guī)律的作用。
