B．Banningwoodcutting.C．Limitinghousingdevelopment. D．Firecontrolmeasures.解析：推理判斷題。第三段提到了造成加利福尼亞州的大樹減少的三個因素：woodcutters，housingdevelopment與aggressivewildfirecontrol。前兩個因素直接與大樹的減少有關，如果能控制住，大樹就不會減少；而第三個因素——控制野火的措施使得加利福尼亞州的森林里滿是跟大樹爭奪資源的小樹，初衷是為了控制野火，這是好的，實則對大樹不利，故D項正確(好心辦壞事)。答案：D29．WhatisamajorcauseofthewatershortageaccordingtoMcIntyre?A．Inadequatesnowmelt. B．Alongerdryseason.C．Awarmerclimate. D．Dampnessoftheair.解析：細節(jié)理解題。根據(jù)最后一段中的“thebiggestfactorsdrivingupwaterstressinthestatehavebeenrisingtemperatures”可知，水不足的主要原因就是氣溫升高(risingtemperatures)，即更加溫暖的氣候，故C項正確。答案：C30．Whatcanbeasuitabletitleforthetext?A．California'sForests：WhereHaveAlltheBigTreesGone?B．CuttingofBigTreestoBeProhibitedinCaliforniaSoonC．WhyAretheBigTreesImportanttoCaliforniaForests?D．PatrickMcIntyre：GrowMoreBigTreesinCalifornia解析：標題歸納題。本文是一篇調查報告，第一段就點出主題：Californiahaslosthalfitsbigtreessincethe1930s。后面具體分析了加利福尼亞州大樹的現(xiàn)狀、造成大樹減少的原因等，A項作為標題最合適。答案：A一、語言能力熟詞生義/詞類活用1．studyn．______________2．declinen．______________3．contributedto________4．theleadauthor______________________5．documentedv．______________________6．takeintoaccount__________調查，研究降幅，下降導致第一作者，主要作者記錄，記載(詳情)考慮到二、思維品質1．閱讀技巧——確定位置，提煉概括段落大意一般而言，每個段落都有一個中心，且通常中心思想會在本段的首句或尾句體現(xiàn)出來，這就是常說的主題句。由于文章內容和體裁的不同，作者的寫作手法也不盡相同，主題句在段落中出現(xiàn)的位置也不固定。一般說來，采用歸納法的段落，細節(jié)表述在前，歸納概括在后，主題句在段尾；采用演繹法的段落，先提出觀點，后演繹例證，由一般到特殊，主題句出現(xiàn)在段首；若作者采用由特殊→一般→特殊的方式，主題句可能出現(xiàn)在段落的中間。有時，作者沒有寫出明顯的主題句，我們要學會根據(jù)段落的內容去概括出主題句，進而歸納出文章的主題。如27題，根據(jù)第二段首句可知研究發(fā)現(xiàn)，加利福尼亞的大樹數(shù)量下降了百分之五十。后面列舉數(shù)目，主要說明數(shù)量急劇下降?？芍髽鋽?shù)量急劇下降的嚴峻形勢。故選A。2．分析長難句并翻譯句子ButincomparingastudyofCaliforniaforestsdoneinthe1920sand1930swithanotheronebetween2001and2010，McIntyreandhiscolleaguesdocumentedawidespreaddeathofbigtreesthatwasevidenteveninwildlandsprotectedfromwoodcuttingordevelopment.[分析]incomparingastudyofCaliforniaforestsdoneinthe1920sand1930swithanotheronebetween2001and2010作__語，句子的主語是McIntyreandhiscolleagues，謂語是documented，awidespreaddeath是賓語。that引導的是____________，修飾death。狀定語從句[翻譯]_______________________________________________________________________________________________________________________________________________________________________________________三、文化素養(yǎng)思考：通過閱讀這篇文章，你如何認為自然和人類社會的關系？______________________________________________________________________________________________________________________但是把20世紀20年代和30年代對加利福尼亞森林的研究和2001年至2010年的研究結果比較，McIntyre和他的同事發(fā)現(xiàn)甚至在野外受到保護，免受砍伐和開發(fā)的大樹也大范圍地死亡。自然和人類社會的關系恰如水與舟的關系，社會發(fā)展不能違背自然規(guī)律，二者關系處理的好壞直接關系到整個人類社會的可持續(xù)發(fā)展。NO.1單詞——在語境中應用，在拓展中記多01核心單詞…………[先識記]請根據(jù)漢語提示完成下列詞塊1．______________anewheadteacher任命一位新校長2．________sb.agreeting揮手向某人致意3．____________thetheatre在劇院旁邊appointwavealongside4．______________withanger因憤怒而發(fā)抖5．__________hispatient使他的病人發(fā)汗6．__________thehorse使馬驚慌7．__________thearrowatthetarget有的放矢8．__________________________surroundings不舒服的環(huán)境9．____________sb.'senthusiasm激起某人的積極性10．be____________________foroneyear保修一年11．be____________insweat渾身大汗tremblesweatpanicshootuncomfortablearouse guaranteedbathed12．a(chǎn)n______________expression憂慮的表情13．in____________life在實際生活中14．a(chǎn)__________________disaster潛在的災禍15．a(chǎn)diving________潛水服16．a(chǎn)pieceof__________________一件設備anxiousactualpotentialsuit equipment[再拓展]請?zhí)钊肜ㄌ杻葐卧~的正確形式1．ThefilmFarewell
