3、遺傳密碼的特點 連續(xù)性、簡并性、通用性5、課堂練習6、作業(yè)布置假如,我們利用(ACU)n核苷酸長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?如何運用實驗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,是我們在課堂上進行探究性學(xué)習活動的良好素材,教師要整理和運用好。千萬不要低估學(xué)生的思維能力,當學(xué)生的思維能力被你想方設(shè)法激發(fā)出來的時候,你會發(fā)現(xiàn)他們的創(chuàng)造力是無窮的。2、探究性學(xué)習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和獲取科學(xué)研究方法,培養(yǎng)合作與分享的精神以及實事求是的科學(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)生積極主動地參與到學(xué)習活動中來,通過他們的思考、討論、爭辯、合作等活動來獲取方法,建構(gòu)知識。
四、說教學(xué)程序(一).溫故知新、導(dǎo)入新課復(fù)習提問: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:對于一個生物體來說,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、突破難點重點的把握: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。教師補充: 患兒的征狀---兩眼較低、耳位低下,存在著嚴重的智力障礙。闡述病因---染色體片段缺失
一、人類遺傳病1.概念2.分類(1)單基因遺傳病(2)多基因遺傳病(3)染色體異常遺傳病①原因②類型3遺傳病的特點4.遺傳病對人類的危害八、說布置作業(yè)在作業(yè)的布置中,我嚴格遵循“重質(zhì)量、輕負擔”的指導(dǎo)思想。第一題主要是為了幫助學(xué)生及時糾正原有的對知識的錯誤理解或片面認識,培養(yǎng)學(xué)生的解題技巧和技能。所以我選用了該題。同時想借助該題培養(yǎng)學(xué)生對問題的科學(xué)的思維方法和探究的精神。幫助學(xué)生提高對信息技術(shù)運用的熟練程度,發(fā)展學(xué)生的信息素養(yǎng)。附作業(yè):1、連線題,請同學(xué)們連線指出下列遺傳各屬于何種類型?(1)苯丙酮尿病 A、單基因遺傳?。?)21三體綜合征(3)抗維生素D佝僂病 B、多基因遺傳?。?)軟骨發(fā)育不全(5)青少年型糖尿病 C、常染色體病2、以生物小組為單位進行人類遺傳病的調(diào)查。
在學(xué)生活動的基礎(chǔ)上,教師總結(jié)歸納:要堅持從群眾中來到群眾中去的工作方法。要求:政府要通過各種途徑,利用各種群眾組織、社會團體廣泛收集群眾意見和建議,認真對待群眾的來信來訪。還要為群眾誠心誠意辦實事,盡心竭力解難事,堅持不懈。通過合作探究,以此來培養(yǎng)學(xué)生的分析能力,探究能力以及透過現(xiàn)象看本質(zhì)的能力,培養(yǎng)學(xué)生獲取信息的能力,自主學(xué)習的能力以及全面看問題的能力,再結(jié)合教師的講授,給學(xué)生一種茅塞頓開的感覺。環(huán)節(jié)四 回歸生活 提升情感我將引導(dǎo)學(xué)生閱讀課本,通過設(shè)置活動探究課,結(jié)合生活實際從時效,便利,實效等方面請學(xué)生評述公民求助或投訴的四種方式的特點和優(yōu)點。在這一過程中,我還會用多媒體展示常用的熱線電話,政府網(wǎng)站上有關(guān)信訪、政務(wù)公開及其他便民利民的欄目,豐富課堂資源。讓學(xué)生閱讀課本,自行歸納知識點,有助于培養(yǎng)學(xué)生自主學(xué)習能力。
環(huán)節(jié)三 案例分析 突破難點我將用多媒體展示兩組反映中學(xué)生參與民主管理的一些作法的圖片,和教材26-27頁的三個鏡頭,然后請同學(xué)們根據(jù)圖片和材料探究以下問題: 1. 聯(lián)系自身實際談?wù)勥@些做法對我們有何啟示? 2.實行農(nóng)村村民自治和城市居民自治有什么意義呢? 3. 我們在實際生活中應(yīng)怎么做?這樣,通過圖片和材料的展示,點明了公民參與民主管理的意義,以此來誘發(fā)學(xué)生已有的真切體驗,感受其境,增強學(xué)生共創(chuàng)想和文明社區(qū)的積極性和情感。同時,我們也希望學(xué)生在學(xué)習本課的知識后,又能做到學(xué)以致用,把所學(xué)的知識真正用到社區(qū)管理中,為所在社區(qū)管理提合理建議,從而真正實現(xiàn)了知識從生活中來,又回到生活中去的理念。環(huán)節(jié)四課堂小結(jié) 課后延伸將用多媒體展示本節(jié)課的知識框架,并注重引導(dǎo)學(xué)生將今天所學(xué)新知識與前面知識聯(lián)系起來,幫助學(xué)生從宏觀上把握各知識點之間的關(guān)系,有利于學(xué)生理解記憶,以此來幫助教師在第一時間掌握學(xué)生學(xué)習信息的反饋,同時培養(yǎng)學(xué)生歸納分析能力、概括能力。
環(huán)節(jié)四 課堂小結(jié) 鞏固知識本節(jié)課我采用線索性的板書,整個知識結(jié)構(gòu)一目了然,為了充分發(fā)揮學(xué)生在課堂的主體地位,我將課堂小結(jié)交由學(xué)生完成,請學(xué)生根據(jù)課堂學(xué)習的內(nèi)容,結(jié)合我的板書設(shè)計來進行小結(jié),以此來幫助教師在第一時間掌握學(xué)生學(xué)習信息的反饋,同時培養(yǎng)學(xué)生歸納分析能力、概括能力。環(huán)節(jié)五 情景回歸,情感升華我的實習指導(dǎo)老師告訴過我們,政治這一門學(xué)科要從生活中來到生活去,所以在課堂的最后布置了課外探究題,以此培養(yǎng)學(xué)生對理論的實際運用能力,同時檢驗他們對知識的真正掌握情況,以此達到情感的升華,本節(jié)課,我根據(jù)建構(gòu)主義理論,強調(diào)學(xué)生是學(xué)習的中心,學(xué)生是知識意義的主動建構(gòu)者,是信息加工的主體,要強調(diào)學(xué)生在課堂中的參與性、以及探究性,不僅讓他們懂得知識,更讓他們相信知識,并且將知識融入到實踐當中去,最終達到知、情、意、行的統(tǒng)一。

(1)宗教有它自身的發(fā)展規(guī)律,不能簡單的用行政力量去消滅或發(fā)展宗教,實行宗教信仰自由政策是遵循宗教發(fā)展規(guī)律,科學(xué)處理宗教問題。(2)宗教信仰自由是憲法賦予公民的民主權(quán)利,實行宗教信仰自由政策有利于加強信教群眾與不信教群眾的團結(jié),引導(dǎo)宗教與社會主義社會相適應(yīng)。2、弘揚科學(xué)精神我國是在馬列主義、毛澤東思想、鄧小平理論、三個代表重要思想指引下的社會主義國家,要建設(shè)社會主義物質(zhì)文明、政治文明,也要建設(shè)社會主義精神文明。加強對人民群眾的科學(xué)世界觀和無神論教育,形成文明、健康、崇尚科學(xué)的社會風尚,逐步消除宗教存在的社會根源何認識根源,在保護宗教信仰自由的同時,創(chuàng)造宗教消亡的條件,這是解決在教問題的根本途徑。3、中學(xué)生作為中國特色社會主義事業(yè)未來的建設(shè)者,要用辯證唯物主義和歷史主義以及現(xiàn)代科學(xué)文化知識武裝自己,弘揚科學(xué)精神,樹立科學(xué)世界觀,承擔起建設(shè)祖國、振興中華的光榮歷史使命。

Where is your the destination?How will you get there?What will you do there?How long will you there?Is there a clear purpose for the trip? 為了提升旅行計劃的層級,還需注意以下幾個方面的問題:1.每段是否有明確清晰的主題;2.用一般現(xiàn)在時代替一般將來時;3.用更高級的形容詞詞匯。例如:表達“好”時,不要總用“nice”,我們還可以用“smart, clean, excellent, exciting, beautiful, wonderful, clever, famous, grand”等表達更具有指向性的詞匯;4.用更高級的動詞詞匯。比如:我們可以用“seem stand, lie .get stay, remain, look . sound, become . keep, grow”等代替"be";
This theme of the part is “ Describe people or things in greater detail”. Students have learned the grammar(restrictive relative clauses) in Book 1, and further review and consolidate its structure “prep+relative pronouns(which/whom)” and the relative adverbs(when, where and why), besides students should understand its form, meaning and functions. In this section, students should be able to express the grammar correctly in daily communication and in the writing. 1. Review the basic usages of relative pronouns and adverbs of attributive clauses . 2. Learn to use some special cases about restrictive relative clauses.3. Learn to write sentences with restrictive relative clauses flexibly according to the context.1. Review the basic usages of relative pronouns and adverbs of attributive clauses .2. Learn to use some special cases about restrictive relative clauses.3. Learn tow rite sentences with restrictive relative clauses flexibly according to the context.Step 1. Observe the following sentences, and mark the relative pronouns and the adverbs. 1. After listening to the scientists who had studied the problems, and citizens who lived near the dam, the government turned to the United Nations for help.2.

What is the head noun ?2. What relative words should be used ?3. What elements do they act in these sentences ?
This teaching period mainly deals with grammar “restrictive relative clauses.” To begin with, teachers should lead students to revise what they have learned about the relative pronouns and relative adverbs. And then, teachers move on to stress more special cases concerning this grammar, such as the “preposition+ relative pronouns which and whom” and cases where we can omit the relative pronouns. This period carries considerable significance to the cultivation of students’ writing competence and lays a solid foundation for the basic appreciation of language beauty. The teacher is expected to enable students to master this period thoroughly and consolidate the knowledge by doing some exercises. 1. Guide students to review the basic usages of relative pronouns and adverbs of attributive clauses.2. Lead students to learn to use some special cases concerning restrictive relative clauses flexibly.2. Enable students to use the basic phrases structures flexibly.3. Strengthen students’ great interest in grammar learning.1. Help students to appreciate the function of relative pronouns and adverbs of attributive clauses in a sentence2. Instruct students to write essays using the proper relative pronouns and adverbs of attributive clauses.本節(jié)語法思考:定語從句在復(fù)合句中的作用是什么? 關(guān)系詞有哪些?定語從句在復(fù)合句中的作用相當于形容詞,它在句中作定語修飾名詞或代詞。他們在先行詞和定語從句之間起到聯(lián)系作用,同時在意義上代表先行詞并在定語從句中擔任一個成分。被定語從句所修飾的詞稱先行詞,定語從句一般放在先行詞的后面。
Listening and Speaking introduces the topic of “Take part in a youth project”. The listening text is an interview about an international youth cultural heritage protection project. More than 20 high school students from seven countries participated in the project. The reporter interviewed two participants Stephanie and Liu Bin. By listening to the text, students can understand the significance of cultural heritage protection, and teenagers can use their knowledge, combine their own interests and advantages, etc. to participate in the action of cultural heritage protection. Listening and Talking introduces the theme of "Talk about history and culture".
