從而破壞土地。此外，這些化學(xué)物質(zhì)會(huì)在土壤和地下水源中長期存在。這影響到在土地上生長的作物，進(jìn)而影響到消化它們的動(dòng)物和人類。很多人擔(dān)憂這些化學(xué)物質(zhì)會(huì)使他們生病甚至致癌。事實(shí)上，像滴滴涕這樣的殺蟲劑在大多數(shù)國家已經(jīng)被禁止了，因?yàn)樗鼈儗θ祟惡铜h(huán)境造成了破壞。至于化肥，通常施了化肥的農(nóng)作物生長得太快，無法供應(yīng)豐富的養(yǎng)分。它們可能外表看起來很美麗，但里面的水通常比必需的礦物質(zhì)多，而且味道也不太好。作為一種選擇，一些農(nóng)夫轉(zhuǎn)向有機(jī)農(nóng)業(yè)，很多顧客在當(dāng)?shù)仉s貨店購物時(shí)轉(zhuǎn)向有機(jī)食品。有機(jī)農(nóng)業(yè)就是不運(yùn)用任何化學(xué)物質(zhì)的簡潔農(nóng)業(yè)。有機(jī)農(nóng)場主注意通過自然的方式保持土壤的肥沃和免受病害。例如，很多有機(jī)農(nóng)場主運(yùn)用來自動(dòng)物的自然糞便作為肥料。這使得他們地里的土壤礦物質(zhì)更豐富。它還使空氣、土壤、水和農(nóng)作物不受化學(xué)物質(zhì)的污染。有機(jī)農(nóng)場主也運(yùn)用很多其他方法來使土壤肥沃。他們常常每年變更每一塊地的作物種類。例如，他們可能一年在一塊地里種玉米或小麥，其次年在那里種豆子。2.種植不同的作物是因?yàn)樗鼈儼阎匾牡V物質(zhì)釋放回土壤，使其為下一批作物生長做好打算。有機(jī)農(nóng)場主還種植多種作物，利用不同深度的土壤來幫助保持土壤肥沃。例如，花生長在地面上，但很多其他蔬菜扎根很深。3.運(yùn)用不同的有機(jī)耕作方法的目的是種植好的食物，同時(shí)避開對環(huán)境或人的健康造成損害。有些人寧愿完全停止在農(nóng)業(yè)中運(yùn)用人造化學(xué)品。4.阻擋他們這樣做的緣由是化學(xué)農(nóng)業(yè)滿意了世界各地對糧食的巨大需求。有機(jī)農(nóng)業(yè)遠(yuǎn)不能滿意那樣的需求。5.因此，要找到一個(gè)合適的解決方案，使人們的餐桌上有足夠的食物，同時(shí)保持人們和環(huán)境盡可能地健康仍舊有很長的路要走。自查語基落實(shí)基本知能Ⅰ.核心詞匯依據(jù)語境寫出正確的單詞1．the________industry化學(xué)工業(yè)2．________farming有機(jī)耕作3．enjoy________respect受到廣泛敬重4．needtimeto________information須要一些時(shí)間來消化信息5．Experienceis________forthisjob.對于這個(gè)工作，閱歷是特別重要的。6．________energy替代能源7．coverall________ofcitylife涵蓋城市生活的各個(gè)方面8．the________oftheproblem問題的根源9．a(chǎn)bottleof________water一瓶礦泉水10．chemical________化學(xué)農(nóng)藥Ⅱ.拓展詞匯依據(jù)語境寫出相應(yīng)的派生詞1．①provide________foryou為你供應(yīng)養(yǎng)分②________food養(yǎng)分食品2．①ata________of30metres在30米深處②takea________breath深深地吸了一口氣3．①an________differentmatter一件完全不同的事情②the________village整個(gè)村莊Ⅲ.重點(diǎn)短語1．____________相應(yīng)地；轉(zhuǎn)而；依次；輪番2．____________例如；比如3．____________做筆記4．____________對……造成損害5．____________至于6．____________關(guān)注7．____________富于；有豐富的……8．____________免受(影響、損害等)9．____________隨著時(shí)間的推移10．____________轉(zhuǎn)向有機(jī)食品Ⅳ.重點(diǎn)句型1．[句型]現(xiàn)在分詞短語作狀語[教材]Whydifferentcropsaregrownisbecausetheyputimportantmineralsbackintotheground,________________________________________．種植不同的作物是因?yàn)樗鼈儼阎匾牡V物質(zhì)帶回土壤，從而使之相宜于種植下一批作物。2．[句型]狀語從句的省略[教材]Thegoalofusingdifferentorganicfarmingmethodsistogrowgoodfood________________________theenvironmentortopeople'shealth.運(yùn)用不同的有機(jī)耕作方法的目的是種植好的糧食，避開損害環(huán)境或者人們的健康。3．[句型]that引導(dǎo)的同位語從句[教材]Whatkeepsthemfromdoingsoisthefact________________________________________________________________________．阻擋他們這樣做的緣由是化學(xué)農(nóng)業(yè)滿意了世界各地對糧食的巨大需求。4．[句型]keepsb./sth.＋adj.(賓補(bǔ))意為“使某人/某物……”[教材]Organicfarmersfocuson________________________andfreeofdiseasethroughnaturalmeans.有機(jī)農(nóng)夫注意通過自然手段保持土壤肥沃和無病害。課堂提升素養(yǎng)探究新知發(fā)展語言學(xué)問1.(教材P55)Forexample,pesticidescandamagethelandbykillingnotonlyharmfulbacteriaandinsects,butalsohelpfulones.例如，農(nóng)藥不僅可以殺死有害的細(xì)菌和昆蟲，還可以殺死有益的細(xì)菌和昆蟲，從而破壞土地?！蚓湫凸剑簄otonly...but(also)．..不僅……而且……(1)句中“notonly...butalso...”結(jié)構(gòu)意為“不僅……而且……”，其中also可以省略。(2)“notonly/just...but(also)．..”連接的兩個(gè)并列成分作主語時(shí)，謂語動(dòng)詞的人稱與數(shù)遵循“就近原則”。[佳句]Asweallknow,readingclassicscannotonlyimproveourstudybutalsoenrichoureverydaylife.眾所周知，閱讀古典文學(xué)不僅提高我們的學(xué)習(xí)，也豐富了我們的日常生活。[練通]——補(bǔ)全句子/單句語法填空①Beijingis________________________________________________________________(不僅是我國的政治中心，而且是我國的經(jīng)濟(jì)中心)．②Notonlythestudentsbutalsotheteacher________(be)againsttheplan.[寫美]——微寫作③它不僅讓我們放松，而且給了我們一個(gè)更接近大自然的機(jī)會(huì)。Notonly________________________butitalsogaveusachancetogetclosertonature.2．(教材P55)Thisaffectsthecropsgrownonthelandand,inturn,theanimalsandhumanswhodigestthem.這影響到在土地上種植的作物，進(jìn)而影響到消化它們的動(dòng)物和人類?！騣nturn相應(yīng)地；轉(zhuǎn)而；依次；輪番(1)byturns輪番；交替地(2)taketurnstodosth.輪番做某事Itisone'sturntodosth.輪到某人做某事[佳句]Theoryisbasedonpracticeandinturnservespractice.理論以實(shí)踐為基礎(chǔ)，反過來又為實(shí)踐服務(wù)。[練通]——單句語法填空①Hespendstoomuchtimeonmaths,which________turnaffectstheprogressofhisothersubjects.②Whenitwasmyturn________(give)aspeech,Iwastooexcitedtospeak.③Whenmymotherwasill,mybrothertookturns________(take)careofher.[寫美]——微寫作④一方面，它不僅有助于強(qiáng)身健體，還相應(yīng)地幫助我們更有效地學(xué)習(xí)。Foronething,notonlydoesithelptobuildupourhealth,butitalsohelpsus________________________________．◎digestvt.&vi.消化vt.領(lǐng)悟；領(lǐng)悟n．文摘(1)digestfood消化食物digesttheinformation領(lǐng)悟信息(2)amonthlynewsdigest每月新聞?wù)猍佳句]Youshouldallowalittletimeafteramealforthefoodtodigest.飯后你應(yīng)當(dāng)留點(diǎn)時(shí)間讓食物消化。[練通]——寫出下列句中digest的詞性和含義⑤Youshouldn'tgoswimminguntilyourfoodhashadachancetodigest.________⑥D(zhuǎn)igestedrapidlybythebody,sugarprovidesaquickenergysource.________⑦ThemagazineshegavemeisReader'sDigest.________⑧Ittookmealongtimetodigestthetheoryputforwardatthemeeting.________3．(教材P55)Theymaylookbeautifulontheoutside,butinsidethereisusuallymorewaterthanessentialminerals,andtheyoftenhavelessflavouraswell.它們可能外表看起來很美麗，但里面通常有更多的水分，而不是基本的礦物質(zhì)，而且它們通常也沒有那么多的味道。◎essentialadj.完全必要的；極其重要的(1)beessentialto對……不行缺少的(2)Itisessentialforsb.todosth.對某人來說做某事是必要的Itisessentialthat...shoulddosth.做某事是必不行少的[佳句]AsfarasI'mconcerned,moneyisnotessentialtohappine
