⑦在我看來, 探索太空是值得的。As far as I am concerned, it is worthwhile to explore the space.Step 10 Writing---draftRecently, students in our class have had heated a discussion on whether space is worth exploring. Students hold different ideas about it.30% of us think space exploration is not worthwhile. They think space is too far away from us and our daily life and is a waste of money. And the money spent on space exploration can be used to solve the earth’s problems such as starvation and pollution.On the other hand，70% think space is worth exploring because we have benefited a lot from it，such as using satellites for communication and weather forecast. What’s more，with further space research，we may solve the population problem by moving to other planets one day. Also，space research will enable us to find new sources to solve the problem of energy shortages on the earth.As far as I am concerned, it is worthwhile to explore the space. Not only can it promote the development of society but also enrich our life. Step 11 Pair workExchange drafts with a partner.

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.

最后，教師對這節(jié)課學習的內(nèi)容做回顧總結(jié)，并讓學生做幾道練習題鞏固一下新知識。依據(jù)：本節(jié)課主要是通過學生對關中文化的了解來學習我國的傳統(tǒng)文化。所以我計劃通過3-5分鐘的設問導課讓學生把注意力轉(zhuǎn)變集中到課堂中，引導學生關注課堂。整體時間安排符合教育學中的最佳時間分配原理和反饋原理。這樣做也有利于優(yōu)化課堂結(jié)構(gòu)、提高教學效率、把主要時間留給學生，把主動權還給學生。針對高三年級學生的層次差異，我進行了分層設置，設置有基礎題和拔高題。這樣做既可以使學生掌握基礎知識，又可以使學有余力的學生有所提高，從而達到拔尖和“減負”的目的。板書設計板書就是微型教案，板書集中體現(xiàn)教學的三維目標、重難點、教學過程，體現(xiàn)教學的特色與特性。

2．講授新課：（約35分鐘）結(jié)合教材內(nèi)容重難點和學生實際，在講課過程中，我對教材內(nèi)容的順序進行了重組，把教材內(nèi)容由原來的兩大部分劃分為三大部分（第一，價值判斷和價值選擇的含義和關系；第二，價值判斷和價值選擇的特征；第三，做出正確的價值判斷和價值選擇的標準）。這一調(diào)整更符合學生的認知結(jié)構(gòu)，便于從整體上把握課本內(nèi)容。在講授過程中，我充分利用課本素材——探究活動為課堂教學服務，此外，利用學生的生活與體驗，挖掘?qū)嵗?，如結(jié)婚要禮由以前的舊三件到現(xiàn)如今的轉(zhuǎn)變，引導學生理解價值判斷和價值選擇的社會歷史性特征，以以《觀祈雨》、以醫(yī)生、藝術家、老學究對于《斷臂的維納斯》這個雕塑的不同見解、以新鮮實例韓國沉船事件和范跑跑為例啟發(fā)學生價值判斷和價值選擇具有主體差異性特征以此突破難點，最后通過設疑、對比、追問正確的價值判斷和價值選擇的標準來深化主題，突出重點。3．課堂小結(jié)：（約2分鐘）強化認識

【討論】只要繼承和弘揚中國傳統(tǒng)文化中傳統(tǒng)美德，就可以構(gòu)建思想道德體系。學生展示：法律中道德規(guī)范。老師展示：法治：以法律的權威性和強制性規(guī)范社會成員的行為(外律)。德治：以道德的說服力和感召力提高社會成員的思想認識和道德覺悟(內(nèi)律)。結(jié)論：既要加強社會主義法制建設，依法治國；也要繼承、發(fā)展、創(chuàng)新傳統(tǒng)美德，加強思想道德建設，以德治國。建立社會主義思想道德體系要與法律法規(guī)相協(xié)調(diào)。設計意圖：設計一個條件型辨析探究題開展討論，把建設思想道德與優(yōu)秀傳統(tǒng)文竹也、法治的關系結(jié)合起來，把課堂探究與課前探究結(jié)合起來，有利于提高學生的思維能力和課堂教學效率。踐行：思想道德建設從我做起你是否認同、選擇下列行為?展示校園現(xiàn)象圖片《作弊》與《小煙民》(略)；展示中學生在家中表現(xiàn)的漫畫《老子、兒子和孫子》(略)；

2、講授新課：在講授新課的過程中，我突出教材的重點，明了地分析教材的難點。還根據(jù)教材的特點，學生的實際、教師的特長，以及教學設備的情況，我選擇了多媒體的教學手段。這些教學手段的運用可以使抽象的知識具體化，枯燥的知識生動化，乏味的知識興趣化。還重視教材中的疑問，適當對題目進行引申,使它的作用更加突出，有利于學生對知識的串聯(lián)、積累、加工，從而達到舉一反三的效果。3、課堂小結(jié)，強化認識：課堂小結(jié)，可以把課堂傳授的知識盡快地轉(zhuǎn)化為學生的素質(zhì)；簡單扼要的課堂小結(jié)，可使學生更深刻地理解政治理論在實際生活中的應用，并且逐漸地培養(yǎng)學生具有良好的個性。4、板書設計我比較注重直觀、系統(tǒng)的板書設計，還及時地體現(xiàn)教材中的知識點，以便于學生能夠理解掌握。
