1．改善城市環(huán)境：治理河流、控制大氣污染物、大力加強(qiáng)綠化建設(shè)為改善城市環(huán)境，上海市全面展開對大氣、河流、噪聲等多方面的治理工作。如蘇州河的治理、降低城市污染物濃度、加強(qiáng)綠化建設(shè)，截止1990年，市區(qū)綠化覆蓋率達(dá)到20.3%。2．改善城市交通、改善居住條件擴(kuò)寬主干道，修建環(huán)城公路，修筑了南浦大橋和揚(yáng)浦大橋，新修城市高架公路和地鐵，改造住宅。3．控制城市規(guī)模建立衛(wèi)星城，開發(fā)新區(qū)，有效地控制城市中心區(qū)的規(guī)模。思考：什么時(shí)候許多國家采取措施保護(hù)和改善城市環(huán)境？你認(rèn)為可以采取哪些措施來保護(hù)和改善城市環(huán)境？上海市保護(hù)和改善城市環(huán)境的措施：上海的衛(wèi)星城有哪些？上海新建了哪個(gè)新區(qū)？目前浦東新區(qū)在上海的地位如何？建立衛(wèi)星城和開發(fā)新區(qū)可以起到什么作用？上海市為改善交通條件，做了哪些工作？

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(fù)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(gè)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(chǔ)設(shè)施以及其他生產(chǎn)、生活服務(wù)設(shè)施，或者共同利用當(dāng)?shù)亓畠r(jià)的勞動(dòng)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(jì)技術(shù)開發(fā)區(qū)就是建立在這種工業(yè)聯(lián)系基礎(chǔ)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(yīng)（1）工業(yè)集聚可以加強(qiáng)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(yùn)輸費(fèi)用和能源消耗，進(jìn)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(jià)格上漲，導(dǎo)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(jià)格相應(yīng)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(jià)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(jià)就達(dá)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(jià)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(dòng)力價(jià)格高反映為產(chǎn)品的價(jià)格高，而勞動(dòng)力數(shù)量又滿足 不了企業(yè)進(jìn)一步擴(kuò)展對勞動(dòng)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(dòng)力價(jià)格和數(shù)量的雙重制約。5．促進(jìn)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(kuò)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.圓柱、圓錐、圓臺的表面積與多面體的表面積一樣，圓柱、圓錐、圓臺的表面積也是圍成它的各個(gè)面的面積和。利用圓柱、圓錐、圓臺的展開圖如圖，可以得到它們的表面積公式：2.思考1：圓柱、圓錐、圓臺的表面積之間有什么關(guān)系？你能用圓柱、圓錐、圓臺的結(jié)構(gòu)特征來解釋這種關(guān)系嗎？3.練習(xí)一圓柱的一個(gè)底面積是S，側(cè)面展開圖是一個(gè)正方體，那么這個(gè)圓柱的側(cè)面積是（ ）A 4πS B 2πS C πS D 4.練習(xí)二：如圖所示，在邊長為4的正三角形ABC中，E，F(xiàn)分別是AB，AC的中點(diǎn)，D為BC的中點(diǎn)，H，G分別是BD，CD的中點(diǎn)，若將正三角形ABC繞AD旋轉(zhuǎn)180°，求陰影部分形成的幾何體的表面積．5. 圓柱、圓錐、圓臺的體積對于柱體、錐體、臺體的體積公式的認(rèn)識(1)等底、等高的兩個(gè)柱體的體積相同．(2)等底、等高的圓錐和圓柱的體積之間的關(guān)系可以通過實(shí)驗(yàn)得出，等底、等高的圓柱的體積是圓錐的體積的3倍．
人教版高中語文必修3《愛的奉獻(xiàn)學(xué)習(xí)議論中的記敘》教案2篇
方法點(diǎn)撥教師：有的同學(xué)敘述事實(shí)論據(jù)時(shí)，不突出重點(diǎn)和精華，不注意取舍，水分太多，有許多的敘述描寫，有時(shí)還有詳細(xì)的故事情節(jié)，文章幾乎成了記敘文，使文章的論點(diǎn)無法得到充分的證明，這是寫議論文的大忌。那么：議論文中的記敘有哪些特點(diǎn)？同學(xué)各抒己見。投影顯示：1.議論中的記敘不是單純的寫人記事，記敘文字是為議論服務(wù)的，其目的是為作者所闡明的道理提供事實(shí)依據(jù)。所以，在記敘時(shí)要求簡潔、概括，舍棄其中的細(xì)節(jié)，僅僅交代清楚事件或者人物的概貌即可，一般不在各種描寫手段上下功夫，只要把能證明觀點(diǎn)的那個(gè)部分、側(cè)面交代清楚就行了。2.議論文中的記敘性文字不得超過總字?jǐn)?shù)的1/3，否則視為文體不當(dāng)。能力提升一、教師：了解了議論文中的記敘的特點(diǎn)，接下來我們看看今天的話題：“愛的奉獻(xiàn)”，你想從哪個(gè)角度立論？有哪些素材？
（6月5日綠色消費(fèi)日）國旗下講話：環(huán)境與發(fā)展
每年的6月5日是世界環(huán)境日，它的確反映了世界人民對環(huán)境問題的重視，表達(dá)了人類對美好環(huán)境的向往和追求。她是聯(lián)合國促進(jìn)全球環(huán)保意識，提高政府對環(huán)境問題的關(guān)注所采取的行動(dòng)。地球是人類和其他物種的共同家園，然而由于人類常常采取亂砍濫發(fā)，竭澤而漁等不良發(fā)展方式，地球上物種滅絕的速度大大加快。生物多樣性喪失正使生態(tài)系統(tǒng)滑向不可恢復(fù)的臨界點(diǎn)，如果地球生態(tài)系統(tǒng)最終發(fā)生不可挽回的惡化，人類文明所賴以生存的相對穩(wěn)定的環(huán)境條件將不復(fù)存在。
