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.

生1:加強對綠色食品的宣傳和扶持力度。當(dāng)前的形勢迫切要求我們發(fā)展綠色食品,因為綠色食品是真正實現(xiàn)可持續(xù)發(fā)展的,做到了發(fā)展經(jīng)濟和環(huán)境保護相結(jié)合,而且有利于增進人民身體健康。但目前綠色食品在市場上難成氣候,主要是宣傳和扶持不夠。生2:綠色食品對環(huán)境、生長過程、加工過程以及運輸?shù)冗^程都有很嚴(yán)格的要求,很多環(huán)境相對優(yōu)良的地區(qū)都是邊遠落后地區(qū),必須給予政策上的扶持和優(yōu)惠,才能降低成本,市場發(fā)展前景才會更加廣闊?;顒优c探究對當(dāng)?shù)鼐G色食品市場情況作調(diào)查并初步分析。活動的實施過程:1.確定調(diào)查研究的目標(biāo)并制定調(diào)查研究的計劃。市場調(diào)查要深入廣大消費者,可以去市場上做調(diào)查,‘對象包括消費者和經(jīng)營者。形式可以是問卷,也可以是現(xiàn)場采訪。弄清楚被調(diào)查者對綠色食品的態(tài)度,是否了解食用綠色食品的意義,是否懂得鑒別綠色食品等。對象力求涉及各個年齡段,多種職業(yè)。2.對問卷調(diào)查進行整理、分析,得出結(jié)論。

過渡:在實際生活中,城市內(nèi)部空間結(jié)構(gòu)并非完全按照這一經(jīng)濟規(guī)律呈現(xiàn),而是更具復(fù)雜性。這說明除了經(jīng)濟因素外,還有很多其他因素在起作用,請大家結(jié)合你的認(rèn)識、圖2.9和案例1:紐約市的少數(shù)民族區(qū)談?wù)勀愕目捶ā#?)其他因素I.收入 —— 形成不同級別住宅區(qū)的常見原因。有能力支付昂貴租金和選擇最佳居住環(huán)境的人,其居住地往往形成高級住宅區(qū)。II.知名度 ——城市內(nèi)某些地區(qū)在歷史、文化或經(jīng)濟方面具有很高的聲譽,這往往會吸引更多新的住宅或商場建在該處,以提高其知名度。III.種族聚居區(qū)的形成 ——在有些城市的某一區(qū)域內(nèi),如果某個種族或宗教團體占優(yōu)勢,就可能形成種族聚居區(qū)。如紐約市的唐人街、哈林區(qū)、小意大利區(qū)等。IV歷史因素——城市的建筑物和街道設(shè)計可以維持久遠,早期的土地利用方式對日后的功能分區(qū)有著深遠的影響。3、城市內(nèi)部空間結(jié)構(gòu)的形成和變化
從右圖“進出口貿(mào)易占全國的比重”可看出,珠三角地區(qū)的外向型經(jīng)濟特征很明顯,但正在緩慢的發(fā)生轉(zhuǎn)變;而長三角地區(qū)的外貿(mào)依存度在10年內(nèi)迅速增長。由此可見,珠三角地區(qū)城市化過程,是伴隨著該地特殊的經(jīng)濟發(fā)展相對自發(fā)地快速推進,缺乏宏觀而理性的規(guī)劃。閱讀通過此閱讀材料,使學(xué)生大致了解以下內(nèi)容深圳作為珠江三角洲地區(qū)迅速城市化的一個典型代表,到目前為止,對其未來發(fā)展道路的構(gòu)想,主要集中在:如何聯(lián)合和依托臨近區(qū)域、聯(lián)合優(yōu)勢資源,擴大發(fā)展空間;如何明確功能,重新定位,合理分工,突出特色?;顒娱L江三角洲地區(qū)城市的協(xié)調(diào)發(fā)展1.讀圖4.28,如果按人口規(guī)模>500萬人、100萬~500萬人、50萬~100萬人、20萬~50萬人和<20萬人將城市分為五級的話,分析長江三角洲地區(qū)城市的等級規(guī)模結(jié)構(gòu)是否合理,這對其城市的協(xié)調(diào)發(fā)展有何影響?
1.根據(jù)下面的材料,歸納珠江三角洲發(fā)展基塘生產(chǎn)有利的地理條件。珠江三角洲地勢低平,河網(wǎng)密布,降水充沛。北回歸線從珠江三角洲的北部穿過。桑樹和甘蔗主要分布于熱帶和亞熱帶。廣州是古代海上絲綢之路的起始地之一。水產(chǎn)品在廣東人的食物結(jié)構(gòu)中占有較大的比重。點撥珠江三角洲地區(qū)發(fā)展基塘農(nóng)業(yè)生產(chǎn)有利條件可以結(jié)合材料,歸納為三個方面:地形、氣候、市場(當(dāng)?shù)睾秃M猓┚唧w分析略。2.圖4.16所示的基塘生產(chǎn)將哪些產(chǎn)業(yè)聯(lián)系起來?哪些副產(chǎn)品(或廢棄物)被充分利用起來?這種聯(lián)系對農(nóng)村經(jīng)濟發(fā)展有什么作用?點撥基塘生產(chǎn)環(huán)節(jié)將種植業(yè)(桑、蔗等)、養(yǎng)殖業(yè)(養(yǎng)蠶、養(yǎng)魚)、工業(yè)(絲廠、糖廠)等幾種產(chǎn)業(yè)緊密的聯(lián)系在一起。在此環(huán)節(jié)中,塘泥、蠶沙(蠶屎)、蠶蛹、繅絲、濾泥、蔗葉等副產(chǎn)品被充分的回收利用。養(yǎng)蠶業(yè)、蔗糖加工業(yè)同塘魚養(yǎng)殖業(yè)緊密結(jié)合,作為一種綜合的經(jīng)營,幾者之間相互依存、相互促進、揚長補短,有機地循環(huán)聯(lián)系起來。
1.閱讀圖5.16,說明產(chǎn)業(yè)向國外轉(zhuǎn)移對日本經(jīng)濟的不利影響。點撥:圖5.16直觀的顯示了產(chǎn)業(yè)轉(zhuǎn)移對日本經(jīng)濟的不利影響:形成“產(chǎn)業(yè)轉(zhuǎn)移出去的多,轉(zhuǎn)移進來的少→國內(nèi)生產(chǎn)投資不足,生產(chǎn)困難→市場萎縮→產(chǎn)業(yè)向外轉(zhuǎn)移,外資不愿進入”的惡性循環(huán)。2.盡管重化工業(yè)的環(huán)境污染比較嚴(yán)重,但是卻能為工業(yè)化的發(fā)展提供堅實的基礎(chǔ),因此成為發(fā)達工業(yè)的象征。日本、韓國的經(jīng)濟發(fā)展都經(jīng)歷了由輕工業(yè)(勞動密集型)到重化工業(yè)(資源密集型和資金密集型)到高科技工業(yè)(技術(shù)密集型)的階段。(1)為什么日本、韓國在重點發(fā)展重化工業(yè)之前,要先發(fā)展勞動密集型工業(yè)?點撥:重化工業(yè)的發(fā)展一方面需要有一定的工業(yè)基礎(chǔ)和技術(shù)工人,另一方面需要投入大量的資金,先發(fā)展勞動密集型工業(yè)有利于利用勞動力資源豐富且廉價的優(yōu)勢,積累資金和造就產(chǎn)業(yè)工人。所以,勞動力豐富的發(fā)展中國家或地區(qū)的工業(yè)化往往從優(yōu)先發(fā)展勞動密集型工業(yè)開始。
4.They were going to find someone to take part in their bet when they saw Henry walking on the street outside.[歸納]1.過去將來時的基本構(gòu)成和用法過去將來時由“would+動詞原形”構(gòu)成,主要表示從過去某一時間來看將要發(fā)生的動作(尤其用于賓語從句中),還可以表示過去的動作習(xí)慣或傾向。Jeff knew he would be tired the next day.He promised that he would not open the letter until 2 o'clock.She said that she wouldn't do that again.2.表示過去將來時的其他表達法(1)was/were going to+動詞原形:該結(jié)構(gòu)有兩個主要用法,一是表示過去的打算,二是表示在過去看來有跡象表明將要發(fā)生某事。I thought it was going to rain.(2)was/were to+動詞原形:主要表示過去按計劃或安排要做的事情。She said she was to get married next month.(3)was/were about to+動詞原形:表示在過去看來即將要發(fā)生的動作,由于本身已含有“即將”的意味,所以不再與表示具體的將來時間狀語連用。I was about to go to bed when the phone rang.(4)was/were+現(xiàn)在分詞:表示在過去看來即將發(fā)生的動作,通??捎糜谠摻Y(jié)構(gòu)中的動詞是come,go,leave,arrive,begin,start,stop,close,open,die,join,borrow,buy等瞬間動詞。Jack said he was leaving tomorrow.
(2) 中國文人的悲秋情結(jié)。3.《荷塘月色》中,作者為什么要離開家來到荷塘散步?4. 思考:作者的心里為何“頗不寧靜?”(教師補充:寫作背景)5. 出門散步后,作者的心情發(fā)生變化了嗎? 有怎樣的變化?6.思考討論:為什么作者說“我”與“地壇”間有著宿命般的緣分,二者有何相似之處?(閱讀1-5段)7.思考:作者從他同病相憐的“朋友“身上理解了怎樣的”意圖“?三、課堂總結(jié)李白說:“天地者,萬物之逆旅也?!比松?,如同一場旅行,在人生的旅途中,時而高山,時而峽谷,時而坦途,時而歧路。我們或放歌,或悲哭,然而,大自然始終以其不變的姿勢深情地看著我們,而我們,也應(yīng)該學(xué)會在與自然的深情對望中,找到生命的契合。正如敬亭山之于李白,故都的秋之于郁達夫,荷塘月色之于朱自清,地壇之于史鐵生,他們從中或得到心靈的慰藉、精神的寄托,或得到生存的智慧與勇氣,最終完成精神的超脫。
這幾段內(nèi)容傳達出的是“要敬畏生命,尊重生命;更要敬畏大自然,尊重大自然,愛護大自然”的主旨內(nèi)涵,因此讓學(xué)生通過自由朗讀的方式,再次體會馮至對這個消逝了的山村的細致的美好的描繪,感悟馮至傳達出的對生命,對自然的理解和思考。5.最后一個自然段的解讀依然是交給學(xué)生,先齊讀課文,再讓學(xué)生自主分享自己的體會或疑惑。但在這一環(huán)節(jié)我也設(shè)計了兩個我認(rèn)為必須解答的兩個問題,一是怎么理解“在風(fēng)雨如晦的時刻”;二是“意味不盡的關(guān)聯(lián)”是指什么。我認(rèn)為這兩個問題一個涉及到寫作背景,一個涉及到對全文主旨的一個整體把握,能夠進一步幫助學(xué)生理解散文的深刻內(nèi)涵和主旨,讓學(xué)生有意識的在閱讀散文過程中通過背景知識進行理解。既尊重學(xué)生的個性化解讀,又能夠讓學(xué)生有意義學(xué)習(xí),完成預(yù)設(shè)的教學(xué)目標(biāo)。如果學(xué)生沒有提到這兩處,那我就需要做出補充。
本章通過學(xué)習(xí)用二分法求方程近似解的的方法,使學(xué)生體會函數(shù)與方程之間的關(guān)系,通過一些函數(shù)模型的實例,讓學(xué)生感受建立函數(shù)模型的過程和方法,體會函數(shù)在數(shù)學(xué)和其他學(xué)科中的廣泛應(yīng)用,進一步認(rèn)識到函數(shù)是描述客觀世界變化規(guī)律的基本數(shù)學(xué)模型,能初步運用函數(shù)思想解決一些生活中的簡單問題。1.了解函數(shù)的零點、方程的根與圖象交點三者之間的聯(lián)系.2.會借助零點存在性定理判斷函數(shù)的零點所在的大致區(qū)間.3.能借助函數(shù)單調(diào)性及圖象判斷零點個數(shù).?dāng)?shù)學(xué)學(xué)科素養(yǎng)1.數(shù)學(xué)抽象:函數(shù)零點的概念;2.邏輯推理:借助圖像判斷零點個數(shù);3.數(shù)學(xué)運算:求函數(shù)零點或零點所在區(qū)間;4.數(shù)學(xué)建模:通過由抽象到具體,由具體到一般的思想總結(jié)函數(shù)零點概念.重點:零點的概念,及零點與方程根的聯(lián)系;難點:零點的概念的形成.
