教師活動:那種“選舉與我無關(guān)”,“選誰都可以”的想法,是公民意識不強(qiáng)、主人翁意識不強(qiáng)的表現(xiàn)。那么,怎樣才能行使好自己的選舉權(quán)呢?請同學(xué)們根據(jù)上面的學(xué)習(xí),談?wù)勛约旱南敕?。學(xué)生活動:思考討論教師點評:2、 如何行使好自己的選舉權(quán)(1)要不斷提高自己參與民主選舉的素養(yǎng),端正參加選舉的態(tài)度,提高選舉能力,選出切實能代表人民利益的人。(2)要增強(qiáng)主人翁責(zé)任感和公民參與意識,積極參加選舉,認(rèn)真行使自己的選舉權(quán)。(3)要不斷提高政治參與能力,在理性判斷基礎(chǔ)上,鄭重投出自己的一票。(三)課堂總結(jié)、點評本節(jié)內(nèi)容講述了我國的選舉方式以及如何珍惜自己的選舉權(quán)利的有關(guān)知識,懂得我國是人民民主專政的社會主義國家,人民當(dāng)家作主,應(yīng)該增強(qiáng)主人翁責(zé)任感,自覺珍惜并運(yùn)用好選舉權(quán),以促進(jìn)我國的民主政治建設(shè),維護(hù)人民的根本利益。
材料說明了什么?探究二:材料分析:2005年12月13日至18日,WTO第六次部長級會議在香港召開。會議經(jīng)過談判通過了《部長宣言》,規(guī)定發(fā)達(dá)成員和部分發(fā)展中成員2008年前向最不發(fā)達(dá)國家所有產(chǎn)品提供免關(guān)稅、免配額的市場準(zhǔn)入;發(fā)達(dá)成員2006年取消棉花的出口補(bǔ)貼, 2013年年底前取消所有形式農(nóng)產(chǎn)品出口補(bǔ)貼。材料體現(xiàn)了世界貿(mào)易組織在國際經(jīng)濟(jì)貿(mào)易領(lǐng)域中發(fā)揮哪些作用?探究三:P97:A、這些圖示,反映出我國利用外資哪些特點?。B、能為我國提高外資利用水平提出些建議嗎?探究四:材料展示:我國是人口眾多的發(fā)展中大國,全國居民每天消費(fèi)總額達(dá)到37億元。每天消費(fèi)糧食75萬噸,相當(dāng)于一個縣級商品糧基地的全年產(chǎn)量;每天消耗豬肉6萬噸,食油1萬噸,糖1.6萬噸,鮮蛋1.8萬噸。每天購買雜志600多萬冊,報紙5000多萬份,需要400量中型載貨汽車才能裝載。
1、第一,材料一和材料二的選舉方式有什么異同?(1)相同點:①都采用了演講和答辯等形式,都帶有競選的性質(zhì);②都采用無記名、直接選舉的方式進(jìn)行投票選舉;③都屬于差額選舉。(2)不同點:①材料一是對村主任進(jìn)行的正式選舉,結(jié)果是直接產(chǎn)生村主任,材料二是對鎮(zhèn)長候選人進(jìn)行的選舉,結(jié)果只是確定鎮(zhèn)長候選人,鎮(zhèn)長人選還有待進(jìn)行正式選舉;②材料一是全體村民都參加選舉,材料二是各戶派代表參加選舉;③材料二比材料一更強(qiáng)調(diào)競選的方式。第二,你還知道哪些選舉方式?除了直接選舉外,還有間接選舉、等額選舉、差額選舉等。第三,你能對這幾種選舉方式的意義和效果,作出自己的評估嗎?這是學(xué)習(xí)中要探究的問題,這里不一定能回答出來,等到學(xué)完本框內(nèi)容后,可以得出比較明確的答案。第四,材料三給了你什么啟示?這個問題不要求統(tǒng)一的答案,能講出一兩點即可。提示如下:(1)新中國成立后,選舉制度經(jīng)歷半個多世紀(jì)的發(fā)展,正在逐步走向完善;
思考提示在階級社會中,社會基本矛盾的解決主要是通過階級斗爭實現(xiàn)的,階級斗爭是推動階級社會發(fā)展的直接動力,當(dāng)舊的生產(chǎn)關(guān)系嚴(yán)重阻礙生產(chǎn)力發(fā)展,需要進(jìn)行變革時,代表舊的生產(chǎn)關(guān)系的沒落階級卻不會自動退出歷史舞臺,利用舊的上層建筑維護(hù)自己的統(tǒng)治,只有代表新生產(chǎn)力發(fā)展方向的階級通過社會革命,推翻沒落的階級統(tǒng)治,才能解放生產(chǎn)力,推動社會向前發(fā)展。所以,階級社會的進(jìn)步往往是通過激烈的社會革命實現(xiàn)的。但是,社會主義社會與階級社會不同,這是因為,社會主義社會中,生產(chǎn)力和生產(chǎn)關(guān)系、經(jīng)濟(jì)基礎(chǔ)和上層建筑之間的矛盾是一種非對抗性矛盾,不需要通過一個階級推翻另一個階級的階級斗爭的方式來解決,只能通過改革實現(xiàn)社會的發(fā)展,通過對生產(chǎn)關(guān)系和上層建筑進(jìn)行改革,實現(xiàn)社會主義的自我完善,從而促進(jìn)社會的發(fā)展。所以,我國經(jīng)濟(jì)體制改革是在堅持社會主義制度的前提下,改革生產(chǎn)關(guān)系和上層建筑中不適應(yīng)生產(chǎn)力發(fā)展的一系列相互聯(lián)系的環(huán)節(jié)和方面。
(2)歷史課本中歷朝歷代的文化發(fā)展。(3)政治生活中關(guān)于綜合國力競爭的相關(guān)知識。(4)了解文化產(chǎn)業(yè)的發(fā)展,深入體會知識經(jīng)濟(jì)、文化經(jīng)濟(jì)現(xiàn)象。五、【方法點津】:(1)堅持理論聯(lián)系實際的方法,感悟文化現(xiàn)象,理解文化內(nèi)涵,分析文化的作用,增強(qiáng)文化學(xué)習(xí)的自覺性。(2)自學(xué)探究。以課本的簡單提示為線索,深入探究文化與經(jīng)濟(jì)、政治的相互交融,探究文化在綜合國力競爭中的地位和作用。(3)集體討論。針對當(dāng)前國際競爭的實質(zhì),探討我國應(yīng)如何發(fā)展文化產(chǎn)業(yè)、發(fā)展文化生產(chǎn)力、增強(qiáng)文化競爭力;討淪為更好地應(yīng)對文化競爭,作為中學(xué)生目前應(yīng)做好哪些準(zhǔn)備。六、【課文導(dǎo)語】:文化,一個我們十分熟悉的詞匯。然而“熟知并非真知”。有人說,文化是知識;有人說,文化是藝術(shù)。究竟什么是“文化”?只要在社會生活中細(xì)細(xì)體味,我們就能真切地感悟“文化”的內(nèi)涵與文化的力量。
A生產(chǎn)方式是人類社會存在和發(fā)展的基礎(chǔ)人要生存必須有吃、穿、住、用等物質(zhì)生活資料,只有生存問題解決了才能談得上社會的存在和發(fā)展,才能從事其他的活動(教育、藝術(shù)、體育、政治)。而要獲得物質(zhì)生活資料,必須從事物質(zhì)資料的生產(chǎn)勞動。在這一活動中,形成了現(xiàn)實的生產(chǎn)力和生產(chǎn)關(guān)系,即生產(chǎn)方式?!舅枷虢逃柯浜蟊厝话ご颍覈罅Πl(fā)展經(jīng)濟(jì),就是為了發(fā)展生產(chǎn)力。發(fā)展是硬道理,中國解決一切問題的關(guān)鍵在與自己的發(fā)展。要積極支持改革開放,積極投身于經(jīng)濟(jì)建設(shè)中去。現(xiàn)在學(xué)好知識將來教育育人,為社會培養(yǎng)更多的合格人才。B生產(chǎn)方式?jīng)Q定著社會的性質(zhì)和面貌社會生活紛繁復(fù)雜,包括經(jīng)濟(jì)生活、政治生活、精神生活、婚姻家庭生活等許多方面。這些方面都受生產(chǎn)方式的制約,有什么樣的生產(chǎn)方式,就有什么樣的社會結(jié)構(gòu);不同的生產(chǎn)方式,表現(xiàn)為不同性質(zhì)的社會形態(tài)。社會的整個面貌只能從生產(chǎn)方式中得到科學(xué)的說明?!九e例】家庭聯(lián)產(chǎn)承包責(zé)任制的產(chǎn)生與推廣1958年的人民公社化運(yùn)用曾使中國農(nóng)民在勞動和分配上都實行絕對的平均主義,大鍋飯的結(jié)果是飯越吃越少,人越過越窮。
1、重點:如何處理主次矛盾、矛盾主次方面的關(guān)系,具體問題具體分析2、難點:弄清主次矛盾、矛盾主次方面的含義四、學(xué)情分析高二學(xué)生具備了一定的抽象思維和綜合分析的能力,但實踐能力普遍較弱。本框所學(xué)知識理論性較強(qiáng),主次矛盾和矛盾的主次方面這兩個概念極易混淆,學(xué)生較難理解。而且本框內(nèi)容屬方法論要求,需要學(xué)生將理論與實踐緊密結(jié)合,學(xué)生在運(yùn)用理論分析實際問題上還比較薄弱。五、教學(xué)方法:1、探究性學(xué)習(xí)法。組織學(xué)生課后分小組進(jìn)行探究性學(xué)習(xí)。在探究性學(xué)習(xí)中進(jìn)行:“自主學(xué)習(xí)”、“合作學(xué)習(xí)”。讓學(xué)生進(jìn)行自主學(xué)習(xí)的目的是:讓學(xué)生作學(xué)習(xí)的主人,“愛學(xué)、樂學(xué)”,并培養(yǎng)學(xué)生終身學(xué)習(xí)的能力;讓學(xué)生進(jìn)行合作學(xué)習(xí)的目的是:在小組分工合作中,在生生互動( 學(xué)生與學(xué)生互動)中,促使學(xué)生克服“以自我為中心,合作精神差,實踐能力弱“等不足,培養(yǎng)綜合素質(zhì)。2、理論聯(lián)系實際法。關(guān)注生活,理論聯(lián)系實際,學(xué)以致用。

另一方面,其余的人反對這個計劃,因為它可能會導(dǎo)致一些不好的影響。7.I hold the belief that space exploration not only enable us to understand how the universe began but also help us survived well into the future.我堅信探索太空不僅能夠使我們了解宇宙的起源而且能夠幫助我們更好地走進(jìn)未來。8.I think we should spend more time and money exploring space so as to provide new and better solutions to people's shortterm and longterm problems.為了給人類的短期和長期問題提供更新和更好的解決方法,我認(rèn)為我們應(yīng)該花更多的時間和金錢來探索太空。9.From my point of view,it is wrong of young people to depend on their telephones too much,which may do harm to both their physical and mental health.在我看來,年輕人過度依賴手機(jī)是不對的,因為它們可能會對他們的身心健康都有害。最近你班同學(xué)就“人類是否應(yīng)該進(jìn)行宇宙探索”這個問題進(jìn)行了激烈的討論。有人認(rèn)為,探索宇宙不僅讓人類更好地了解宇宙的發(fā)展,還可以用來指導(dǎo)農(nóng)業(yè)生產(chǎn),以及把一些探索太空的高新技術(shù)用于現(xiàn)實生活;也有一些人認(rèn)為探索太空花掉了大量的人力物力;影響了人們的生活水平。請你根據(jù)以下情況寫一篇報告并發(fā)表自己的觀點。注意:1.寫作內(nèi)容應(yīng)包括以上全部要點,可適當(dāng)發(fā)揮,使上下文連貫;
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.

晶晶和亮亮是兩滴巖漿,他們生活在地球內(nèi)部的:巖漿之家。一天,他們得到批準(zhǔn),與其他同伴一起到地球表面進(jìn)行旅行。他們飛快地奔向地表,半路上,晶晶覺得累了,于是就與亮亮約好,在地表匯合。亮亮沒有停步,與其他伙伴一起跳出地表,并沿著山坡往低處流動。忽然,亮亮發(fā)現(xiàn)自己不能再動了,不禁問旁邊的同伴這是怎么一回事。同伴笑著說:“別擔(dān)心,只不過你已經(jīng)不再是巖漿罷了?!眴栴}1、為什么同伴說亮亮已經(jīng)不再是一滴巖漿了?2、你認(rèn)為亮亮還可以繼續(xù)他的地表旅行嗎?請說明原因。(由學(xué)生討論回答。)過了好長的一段時間,亮亮發(fā)現(xiàn)自己的個頭變小了,并隨著風(fēng)和流水往前運(yùn)動了。亮亮邊走邊欣賞著地表美麗的風(fēng)光。忽然,亮亮發(fā)現(xiàn)一個熟悉的身影,認(rèn)真一看,原來是晶晶。亮亮驚訝地問:“你是怎么來到地表的?”3、請你簡要推測晶晶到達(dá)地表的過程。(由學(xué)生討論回答。)亮亮和晶晶又一起踏上旅程。
1.促使美國成為一個移民國家的因素是:①美洲屬于未開發(fā)的新大陸,需要大量的勞動力;②歐洲失業(yè)工人和破產(chǎn)農(nóng)民增加,人們?yōu)榱俗非蟾玫慕?jīng)濟(jì)待遇遷往美洲;③新航線的開辟為人們順利遷移掃除了障礙;④殖民擴(kuò)張是人口遷移的促進(jìn)因素,加快了人口遷移的過程。導(dǎo)致美國人口在本土范圍內(nèi)頻繁遷移的原因,歸納起來有:第一次人口遷移是戰(zhàn)爭因素,第二次是城市化;第三次是自然環(huán)境、經(jīng)濟(jì)環(huán)境的變化;第四次是經(jīng)濟(jì)格局的變化,即西部和南部新資源的發(fā)現(xiàn)和新興工業(yè)的發(fā)展。2.我國古代的人口遷移,深受統(tǒng)治者及其行政力量的束縛。封建帝王為了加強(qiáng)本國的經(jīng)濟(jì)和軍事實力,對人口遷移嚴(yán)加控制。只有當(dāng)戰(zhàn)亂發(fā)生的時候,這種控制才得到削弱,人們?yōu)榱硕惚軕?zhàn)亂,尋找安定的生活環(huán)境,不得不進(jìn)行大規(guī)模的遷移。我國近幾十年的人口遷移主要是由生產(chǎn)資料和勞動力數(shù)量上的地區(qū)分布不平衡造成的,是經(jīng)濟(jì)因素在起主導(dǎo)作用,與古代的人口遷移截然不同。
