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.

人教版高中歷史必修3“罷黜百家獨(dú)尊儒術(shù)”說課稿2篇
1、漢武帝尊儒的措施：（1）政治方面：起用很多儒學(xué)家參與國家大政。他規(guī)定，地方定期選出孝子、廉吏當(dāng)中央任官，甚至還擢升平民、儒士為相。這明顯擴(kuò)大了官員的隊(duì)伍，提高了官員的文化素質(zhì)，鞏固了封建統(tǒng)治基礎(chǔ)，成為漢武帝文治武功的重要組成部分。也給后世封建王朝在用人方式方法上面提供了寶貴的借鑒和啟迪。（2）思想方面：采納董仲舒的建議，“罷黜百家 獨(dú)尊儒術(shù)”（3）教育方面：儒家經(jīng)典“五經(jīng)”為國家規(guī)定的教科書。興辦太學(xué)和設(shè)立地方學(xué)校進(jìn)行儒學(xué)教育。公元前136年，漢武帝正式規(guī)定《詩》、《書》、《禮》、《易》、《春秋》為“五經(jīng)”；前124年，又在長安興辦太學(xué)，規(guī)定太學(xué)生員為博士弟子，一律由儒家五經(jīng)博士負(fù)責(zé)教授，學(xué)完經(jīng)考試合格后即可到政府任官。這是封建國家利用政權(quán)的力量興辦教育、提倡儒學(xué)，其必然對整個(gè)社會(huì)的教育事業(yè)有一定的導(dǎo)向作用。

二、應(yīng)用生長調(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生長調(diào)節(jié)劑。生2：我們小組查的資料是關(guān)于小麥?zhǔn)褂蒙L調(diào)節(jié)劑。小麥應(yīng)用植物生長調(diào)節(jié)劑，可以調(diào)節(jié)植株的生長發(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：我找了一篇生長調(diào)節(jié)劑對矮牽牛大型穴盤生產(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)到一些書本上沒有的知識(shí)，請大家結(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)問題。師：你知道哪些農(nóng)產(chǎn)品在生產(chǎn)過程中使用了植物生長調(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)過程中施用植物生長調(diào)節(jié)劑，會(huì)不會(huì)影響農(nóng)產(chǎn)品的品質(zhì)？師：如果你是水果銷售員，面對半青不熟的水果，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)通過資料分析討論以下三個(gè)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(jìn)入情感態(tài)度的教育。除此之外，我還設(shè)計(jì)一個(gè)開放性的作業(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、板書、倡議書等），讓學(xué)生把愛心付諸于實(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)，而是可愛的有用的。通過交流，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？開展世界艾滋病運(yùn)動(dòng)有什么意義？

（3）內(nèi)陸和中西部城鎮(zhèn)主要以煤和火電為主；廣大農(nóng)村和邊遠(yuǎn)地區(qū)大多正從使用農(nóng)作物秸稈等生物能源。（4）人均能源資源不足。我國是世界第三大能源生產(chǎn)國和第二大能源消費(fèi)國，而我國能源短缺，特別是油氣資源短缺已成為制約我國經(jīng)濟(jì)發(fā)展的重要因素。相關(guān)數(shù)據(jù)——煤炭、石油和天然氣的人均資源占有量只有95t，世界平均值為209t，約是世界人均值的1/2；我國人均石油可采儲(chǔ)量3t，世界平均值為28t，約為世界平均值的1/10。我國人均能源消費(fèi)量不足1.2噸標(biāo)準(zhǔn)煤，居世界89位，不足世界人均能源消費(fèi)水平的一半，僅占發(fā)達(dá)國家的1/5～1/10。其中人均消費(fèi)650kg標(biāo)準(zhǔn)煤，是世界平均額的95%；人均消費(fèi)石油相當(dāng)145kg標(biāo)準(zhǔn)煤，為世界平均數(shù)的16.8%；人均消費(fèi)天然氣相當(dāng)17.7kg標(biāo)準(zhǔn)煤，為世界平均數(shù)的3.9%；人均消費(fèi)電力501.5kWh，為世界平均水平的25%。（5）是能源消費(fèi)結(jié)構(gòu)不合理，突出存在著一低兩高：即電能消費(fèi)比例低，非商品生物能源消費(fèi)量高，一次性商品能源消費(fèi)中原煤消費(fèi)比重高。原煤消費(fèi)達(dá)到75%，遠(yuǎn)高于26.2%的世界平均水平。
人教版新課標(biāo)高中物理必修2圓周運(yùn)動(dòng)說課稿3篇
設(shè)計(jì)意圖：通過設(shè)疑、討論及學(xué)生的親身體驗(yàn)與教師的引導(dǎo)，得到描述圓周運(yùn)動(dòng)快慢的兩個(gè)物理量，也就成功的打破了學(xué)生在認(rèn)識(shí)上的思維障礙，突破了物理概念教學(xué)的難點(diǎn)。在解決線速度和角速度的問題之后，我將引領(lǐng)學(xué)生學(xué)習(xí)勻速圓周運(yùn)動(dòng)的概念以及勻速圓周運(yùn)動(dòng)中線速度、角速度的特點(diǎn)。并引出勻速圓周運(yùn)動(dòng)中周期、轉(zhuǎn)速的知識(shí)。為了加深學(xué)生對線速度、角速度與半徑關(guān)系的認(rèn)識(shí)，我設(shè)計(jì)了第三個(gè)學(xué)生體驗(yàn)活動(dòng)：四名學(xué)生以我為圓心做圓周運(yùn)動(dòng)，四名學(xué)生始終并列，這時(shí)里圈同學(xué)走動(dòng)不急不慢，而外圈同學(xué)則要小跑。通過學(xué)生的活動(dòng)，不難發(fā)現(xiàn)在角速度相同的情況下，半徑越大的線速度也越大。定性的得到了線速度、角速度與半徑的關(guān)系。接下來讓學(xué)生利用所學(xué)知識(shí)推導(dǎo)線速度、角速度與半徑的關(guān)系。設(shè)計(jì)意圖：這樣就通過設(shè)疑、學(xué)生猜想、體驗(yàn)、推導(dǎo)的方式得到了結(jié)論，突破了本節(jié)課的難點(diǎn)即線速度、角速度與半徑的關(guān)系。
