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)合你的認識、圖2.9和案例1:紐約市的少數(shù)民族區(qū)談談你的看法。(2)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。
1.生產(chǎn)上的聯(lián)系:有投入——產(chǎn)出的關(guān)系工業(yè)生產(chǎn)的過程復雜,工序繁多,往往需要經(jīng)過多家工廠的加工才能完成一種產(chǎn)品的生產(chǎn)過程。因此,在這些工廠之間就存在著產(chǎn)品與原料的聯(lián)系。一家工廠生產(chǎn)的產(chǎn)品是另一家工廠的原料,這兩家工廠之間就形成了工序上的工業(yè)聯(lián)系。2.非生產(chǎn)上的聯(lián)系:如地理空間上的聯(lián)系布局在同一個工業(yè)區(qū)內(nèi),共同利用工業(yè)區(qū)的道路、供水、供電、通信等基礎設施以及其他生產(chǎn)、生活服務設施,或者共同利用當?shù)亓畠r的勞動力,形成了空間利用上的工業(yè)聯(lián)系。我國許多地方的經(jīng)濟技術(shù)開發(fā)區(qū)就是建立在這種工業(yè)聯(lián)系基礎上的。(二)工業(yè)集聚1.形成具有工業(yè)聯(lián)系的一些工廠往往近距離地聚集起來,形成工業(yè)集聚現(xiàn)象。2.工業(yè)集聚可獲得效應(1)工業(yè)集聚可以加強企業(yè)間的信息交流和技術(shù)協(xié)作,降低中間產(chǎn)品的運輸費用和能源消耗,進而降低生產(chǎn)成本,提高生產(chǎn)效率和利潤,取得規(guī)模效益。
1.國家石油價格上漲,導致依賴于國際石油而建立起來的日本重化工業(yè)的制造成本提高,產(chǎn)品價格相應提高,削弱了日本重化工產(chǎn)品在國際市場上的競爭力。2.日元 的大幅度升值,意味著日本產(chǎn)品在國際市場上的價格大幅度提高。例如,同樣的日本產(chǎn)品,如果原來在國際市場上賣1美元,日元升值1倍后其在國際市場上的售價就達2美元。所以,以國際市場為依托的日本傳統(tǒng)產(chǎn)業(yè)只好紛紛向海外轉(zhuǎn)移。3.自身市場滿足不了發(fā)展需求,國際市場上亞洲發(fā)展中國家和地區(qū)的同類產(chǎn)品具有明顯的價格優(yōu)勢。所以,日本企業(yè)在其國內(nèi)發(fā)展的空間很小。4.勞動力價格高反映為產(chǎn)品的價格高,而勞動力數(shù)量又滿足 不了企業(yè)進一步擴展對勞動力的需求。所以,日本從事傳統(tǒng)產(chǎn)業(yè)的國內(nèi)企業(yè)生產(chǎn)受勞動力價格和數(shù)量的雙重制約。5.促進日本企業(yè)生產(chǎn)的區(qū)位選擇向國土的南、北部和海外擴展。6.“技術(shù)立國”的政策明顯對傳統(tǒng)產(chǎn)業(yè)在國內(nèi)生產(chǎn)不利,即企業(yè)生產(chǎn)要么向知識技術(shù)密集型轉(zhuǎn)換(這需要大量的投資),要么轉(zhuǎn)向海外。
1.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。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?shù)睾秃M猓?.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?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?;旧辖鉀Q了桑、蔗的肥料和蠶、魚的飼料問題。不僅養(yǎng)蠶、蔗糖加工和養(yǎng)魚生產(chǎn)穩(wěn)定,而且成本也大大降低。
角色扮演:學生扮演政府官員、熱帶叢林土著居民、 世界環(huán)保組織官員、開發(fā)商等角色,從角色的立場討論亞馬孫河流域熱帶雨林的開發(fā)活動規(guī)則: 每個小組認領(lǐng)一種角色,用5分鐘的時間討論和整理思路,然后推薦一位代表做中心發(fā)言,小組的其他同學可以隨時補充。發(fā)言時請說 明所扮演的角色,盡可能多的發(fā)表建設性意見。如果需要,可以上臺展示材料【學生互動】 風云辯論:雨林破壞誰之錯?正方觀點:雨林破壞,亞馬孫地區(qū) 的國家和 居民應負主要責任反方觀點: 雨林破壞,發(fā)達國家應負主要責任 【師生小結(jié)】 雨林的開發(fā),既有發(fā)展中國家經(jīng)濟的需要,也有發(fā)達國家國際市場的牽動。保護雨林,是全人類的共同責任,尤其發(fā)達國家應該承擔更多的責任。保護亞馬遜雨林符合長遠利益和全球利益。但這與雨林所在地國家的發(fā)展產(chǎn)生了矛盾,如何解決之一矛盾是雨林開發(fā)與保護的關(guān)鍵。【過渡承轉(zhuǎn)】 綠色和平組織警告說,如果不采取有效措施制止對森林的破壞,80年內(nèi)熱帶雨林可能完全從地球上消失。開發(fā)還是保護?這是雨林的兩種前途,也

1.用CAI課件模擬汽車的啟動過程。師生共同討論:①如果作用在物體上的力為恒力,且物體以勻速運動,則力對物體做功的功率保持不變。此情況下,任意一段時間內(nèi)的平均功率與任一瞬時的瞬時功率都是相同的。②很多動力機器通常有一個額定功率,且通常使其在額定功率狀態(tài)工作(如汽車),根據(jù)P=FV可知:當路面阻力較小時,牽引力也小,速度大,即汽車可以跑得快些;當路面阻力較大,或爬坡時,需要比較大的牽引力,速度必須小。這就是爬坡時汽車換低速擋的道理。③如果動力機器在實際功率小于額定功率的條件下工作,例如汽車剛剛起動后的一段時間內(nèi),速度逐漸增大過程中,牽引力仍可增大,即F和v可以同時增大,但是這一情況應以二者乘積等于額定功率為限度,即當實際功率大于額定功率以后,這種情況不可能實現(xiàn)。
(五)平拋運動規(guī)律的應用例1:一架老式飛機在高出海面45m的高處,以80m/s的速度水平飛行,為了使飛機上投下的炸彈落在停在海面上的敵船,應該在與轟炸目標的水平距離為多遠的地方投彈?不計空氣阻力。分析:對于這道題我們可以從以下幾個方面來考慮:(1)從水平飛行的飛機上投下的炸彈,做什么運動?為什么?(2)炸彈的這種運動可分解為哪兩個什么樣的分運動?3)要想使炸彈投到指定的目標處,你認為炸彈落地前在水平方向通過的距離與投彈時飛機離目標的水平距離之間有什么關(guān)系?拓展:1、式飛機在高出海面45m的高處,以80m/s的速度水平飛行,尾追一艘以15m/s逃逸的敵船,為了使飛機上投下的炸彈正好擊中敵船,應該在與轟炸目標的水平距離為多遠的地方投彈?不計空氣阻力。2、在一次摩托車跨越壕溝的表演中,摩托車從壕溝的一側(cè)以速度v=40m/s沿水平方向向另一側(cè),壕溝兩側(cè)的高度及寬度如圖所示,摩托車可看做質(zhì)點,不計空氣阻力。(1)判斷摩托車能否跨越壕溝?請計算說明(2)若能跨過,求落地速度?
3.進一步體會力是產(chǎn)生加速度的原因,并通過牛頓第二定律來理解勻速圓周運動、變速圓周運動及一般曲線運動的各自特點。(三)、情感、態(tài)度與價值觀1.在實驗中,培養(yǎng)學生動手、探究的習慣。2.體會實驗的意義,感受成功的快樂,激發(fā)學生探究問題的熱情、樂于學習的品質(zhì)。教學重點1.體會牛頓第二定律在向心力上的應用。2.明確向心力的意義、作用、公式及其變形,并經(jīng)行計算。教學難點1.對向心力的理解及來源的尋找。2.運用向心力、向心加速度的知識解決圓周運動問題。教學過程(一)、 引入新課:復習提問:勻速圓周運動的物體的加速度——向心加速度,它的方向和大小有何特點呢?學生回答后進一步引導:那做勻速圓周運動物體的受力有什么特點呢?是什么力使物體做圓周運動而不沿直線飛出?請同學們先閱讀教材
【教學目標】 (1)、區(qū)位的含義;(2)、農(nóng)業(yè)區(qū)位選擇的主要因素;(3)、農(nóng)業(yè)地域的概念、類型。【教學重、難點及解決辦法] 】重點:影響農(nóng)業(yè)的主要自然區(qū)位因素;社會經(jīng)濟因素及其發(fā)展變化對農(nóng)業(yè)區(qū)位的影響。難點:運用所學原理,合理評價選擇農(nóng)業(yè)區(qū)位。解決方法:知識講授、案例分析、問題探究與討論【教學準備】多媒體課件缺勤登記:三、自然因素的利用和改造1.充分利用:光熱水土并擴大范圍2.及時改造:使之更合理地發(fā)展農(nóng)業(yè)四、社會經(jīng)濟因素的發(fā)展變化1.市場區(qū)位及需求的變化2.交通運輸條件的改善和冷藏技術(shù)的發(fā)展,擴展了市場
全班齊讀第五段內(nèi)容。請一位同學分析,接著讓這位同學按他分析的讀一遍。3、4兩自然段的平緩之后,第5段作者的情感再次抬升。為了滿足這種情感的張揚,作一口氣連用了四個排比句式“現(xiàn)在是……時候”,一方面這是情感發(fā)泄的需要,另一方面這種排山倒海的語勢也加強了內(nèi)容的表達,極強地突出了現(xiàn)實為自由、平等而戰(zhàn)的重要性。四、學會演講我們剛才細讀了課文,但讀和講是有區(qū)別的。所謂演講,是一門語言藝術(shù),它的主要形式是“講”,即運用有聲語言并追求言辭的表現(xiàn)力和聲音的感染力;同時還要輔之以“演”,即運用面部表情、手勢動作、身體姿態(tài)乃至一切可以理解的態(tài)勢語言,使講話“藝術(shù)化”起來,從而產(chǎn)生一種非凡的藝術(shù)魅力。那么,接下來就假設一下假如你是馬丁·路德·金,你會怎樣去講這篇演講辭。
2.表示現(xiàn)階段正在進行的被動動作(該動作在說話的瞬間未必正在進行)。Many interesting experiments are being carried out these days.(說話時,并不一定正在進行)3.表示一種經(jīng)常性的被動行為,常和always,constantly 等表示頻度的副詞連用,這種用法常常帶有贊揚或厭惡的感情色彩。He is always being praised by the leader.4.表示按計劃或安排主語將要承受謂語動詞所表示的動作(僅限于少數(shù)及物動詞)。A party is being held tonight.Step 4 Special cases1.像take care of, look after, talk about, think of等動詞與介詞構(gòu)成的短語用于現(xiàn)在進行時的被動語態(tài)時, 其中的介詞不可省略。The ways to stop illegally hunting are being talked about. 2.可與部分情態(tài)動詞連用,表示對正在發(fā)生的事情的推測。She may be being punished by her mother.3.有時可表示按計劃或安排將要進行的一個被動動作。A celebration is being held this weekend for his success.4.某些表示“狀態(tài)、心理活動、存在”等的動詞,如have,want,need,love,一般不用現(xiàn)在進行時的被動語態(tài),而常用一般現(xiàn)在時的被動語態(tài)。With the population increasing,more land is needed.5.“be+under/in+n.”可表示現(xiàn)在進行時的被動意義。My computer is under repair.=My computer is being repaired.

This unit is about history and traditions. From the opening page, we can know that this unit will introduce the history and traditions around the world. As Marcus Garvey says “A people without the knowledge of their past history, origin and culture is like a tree without roots”, it is important for students to realize the importance and value of knowing the history and traditions and their further meanings. And this part ( listening and speaking ) is divided into two parts: Part A---share views on historic sites, Part B ---talk about a visit to a historic tourist destination. By talking with a foreigner, the speakers introduce the historic attractions and their cultures. Part A is that William, a British student, who was going to visit the Confucius Temple and a Chinese student, Xiao Kong, who was going to the Confucius Temple to meet with the members of the research group, went together and exchanged their views on the Confucius Temple, Confucius, Confucius' descendants and Confucius' educational thoughts. Part B is a conversation between Xiao Yan, a youth hostel receptionist and Paul, a backpacker about the feelings and experience after visiting the Chinese famous tourist attraction Pingyao.1. Guide students to understand the content of listening texts in terms of the whole and key details; 2. Cultivate students' ability to guess the meaning of words in listening; discuss with their peers how to talk about historic spots and great person.3.

This teaching period mainly deals with grammar: The past participle is used as attributive and objective complement.1. Guide students to review the basic usages of the past participle used as attributive and objective complement.2. Lead students to learn to use some special cases concerning the past participle used as attributive and objective complement flexibly.3. Strengthen students’ great interest in grammar learning.1. Help students to appreciate the function of the past participle used as attributive and objective complement.2. Instruct students to write essays using the past participle used as attributive and objective complement.Step1:溫故而知新。Analyze the underlined phrases and then sum up the common usages of the past participles.1.(教材P41)They had castles built(build) all around England, and made changes to the legal system.2.(教材P42)They use the same flag, known(know) as the Union Jack,...3.(教材P42)Judy and I had our car parked(park) in an underground car park near Trafalgar Square, where we could get our car battery charged(charge).Common points: f the past participle used as attributive and objective complement.Step 2:過去分詞作定語時的意義1.及物動詞的過去分詞作定語,在語態(tài)上表示被動;在時間上,常表示動作已經(jīng)發(fā)生或完成,有時也不表示時間性。Our teacher watched us doing the experiment and gave us a satisfied smile at last.我們的老師看著我們做實驗,最后給了我們一個滿意的微笑。The plan put forward at the meeting will be carried out soon.會上提出的計劃將很快被執(zhí)行。2.不及物動詞的過去分詞作定語,它不表示被動意義,只強調(diào)動作完成。Many little kids like gathering fallen leaves in the yard.

Step1:自主探究。1.(教材P52)Born(bear) in the USA on 2 January 1970, Whitacre began studying music at the University of Nevada in 1988.2.(教材P52) Moved(move) by this music, he said, “It was like seeing color for the first time.”3.(教材P56)I was very afraid and I felt so alone and discouraged(discourage).4.(教材P58)Encouraged(encourage) by this first performance and the positive reaction of the audience, I have continued to play the piano and enjoy it more every day.Step2:語法要點精析。用法1:過去分詞作表語1).過去分詞可放在連系動詞be, get, feel, remain, seem, look, become等之后作表語,表示主語所處的狀態(tài)Tom was astonished to see a snake moving across the floor.湯姆很驚訝地看到一條蛇正爬過地板。Finally the baby felt tired of playing with those toys.終于嬰兒厭倦了玩那些玩具。注意:1).過去分詞作表語時與被動語態(tài)的區(qū)別過去分詞作表語時,強調(diào)主語所處的狀態(tài);而動詞的被動語態(tài)表示主語是動作的承受者,強調(diào)動作。The library is now closed.(狀態(tài))圖書館現(xiàn)在關(guān)閉了。The cup was broken by my little sister yesterday.(動作)昨天我妹妹把杯子打碎了。2)感覺類及物動詞的現(xiàn)在分詞與過去分詞作表語的區(qū)別過去分詞作表語多表示人自身的感受或事物自身的狀態(tài),常譯作“感到……的”;現(xiàn)在分詞多表示事物具有的特性,常譯作“令人……的”。
(4)Now we have heard a number of outstanding speeches ... 我們已經(jīng)聆聽了許多精彩的發(fā)言……(5)Because we wanted the nations of the world, working together, to deal with ... 因為我們希望全世界各國團結(jié)起來去應對……(6)And if we do not act ... 如果我們不采取行動……(7)Now, I share the concerns that have been expressed ... 我也同意對于……表達的擔心(8)Let us show the world that by working together we can ... 讓我們告訴全世界,通過一起努力我們可以……(9)It is now time for us to ... 是時候我們……(10)And I have always wished that ... 我一直希望……(11)Thank you for letting me share this day with me.感謝你們和我共度這一天。實踐演練:假如你是高中生李華,你校將舉辦一次以“音樂”為主題的演講比賽,請你按照主題,寫下你的演講稿。注意:詞數(shù)100左右。First of all, thank you for listening to my speech. My topic is: love music like love yourself.Music is like the air we need to maintain our normal lives around us. You can't imagine how terrible a world without music would be. Movies and TV shows have no music, only dry conversations and scenes; mobile phones only vibrations; streets only noisy crowds; cafes, western restaurants only depressed meals. What a terrible world it is!As a student, I hope we all can enjoy the fun brought by music in our spare time. Instead of just listening to music, we can even make our own music. Let's enjoy the fun of music!Thanks again for your attention!
