动名词的主动式或不定式的被动式作宾语，意义没有区别。如：榿贰轲誊壟该槛鲻垲赛。Thewindowneeds／requires／wantscleaning／tobecleaned．邁茑赚陉宾呗擷鹪讼凑。4.在begin,continue,love,like,hate,prefer,intend,start后用动名词和嵝硖贪塒廩袞悯倉華糲。用不定式作宾语均可，意义没有多大区别。5.动词forget,goon,mean,regret,remember,stop,try,beusedto,can'thelp后跟动名词和跟不定式区别较大，须注意。该栎谖碼戆沖巋鳧薩锭。forget,regret,remember后跟动名词，动名词表示已经发生的动作；后跟不定式表示将要发生的动作。劇妆诨貰攖苹埘呂仑庙。22/22\nTheThirdPeriodExtensiveReadingTeachinggoals教学目标1.Targetlanguage目标语言a.重点词语chemical,bacteria,pest,leadto,discovery,nutrition,keep…freefrom,root臠龍讹驄桠业變墊罗蘄。b.重点句型Withthesediscoveries,somefarmerandmanycustomersarebeginningtoturntoorganicfarming.鰻順褛悦漚縫冁屜鸭骞。Overthepasthalfcentury,usingchemicalfertilizershasbecomeverycommoninfarming.穑釓虚绺滟鳗絲懷紓泺。2.Abilitygoals能力目标EnableSstomasterthemainideaofthetextandknowthewaysoforganizingarticles.隶誆荧鉴獫纲鴣攣駘賽。3.Learningabilitygoals学能目标HelpSslearnhowtoenlargethewordsandstructuresofthesametopic.浹繢腻叢着駕骠構砀湊。Teachingimportantanddifficultpoints教学重难点1.Howtograspthemainideaofthepassage.2.Howtograspthewordsandphrasesandbeabletousethemfreely.鈀燭罚櫝箋礱颼畢韫粝。Teachingmethods教学方法Showquestions,readfast,findthemainideas,andthenreadcarefullyandfinishallthetasks.惬執缉蘿绅颀阳灣熗鍵。Teachingaids教学准备Arecorderandaprojector.Teachingprocedures&ways教学过程与方法22/22\nStepⅠGreetingandrevisionT:Morning,boysandgirls!DoyoustillrememberthepoemIgaveyoulasttime?贞廈给鏌綞牵鎮獵鎦龐。Ss:Yeah!T:Who’dliketoreciteittothewholeclass?S1:Me.Listen!心平何劳持戒，行直何用修禅，恩则孝养父母，义则上下相怜。让则尊卑和睦，忍则众恶无喧。若能钻木取火，淤泥定生红莲。嚌鲭级厨胀鑲铟礦毁蕲。T：Verygood!Thankyou.Ithinkknowledgeisimportant.Butwisdomismoreimportant.Ifapersononlyknowshowtoinventandcreatsomething,butdoesn’tthinkoverwhetherhisinventionscanbringpeoplethetruehappiness;orheonlydoesthingforhisorhisgroup’sinterest.Moreover,sometimeswhathemadecandoharmtosociety,thenhewillbethemostdangerouspersonintheworld.Thepoemaboveisveryeasytounderstand.Ifyoudothingsasittellsus,youcanturnouttobeawisemanwhowillbringtheworldthehappiness.薊镔竖牍熒浹醬籬铃騫。Well,todaywearegoingtodosomereading.PleaseturntoPage13.We’llreadthismaterialfirst.齡践砚语蜗铸转絹攤濼。StepⅡReadingTherearethreetasksinthisstep.First,teachercanaskstudentstoreadthearticlesoneparagraphbyoneparagraph.Askthemsomequestionsaboutthesepassages.Therearethreeparagraphsinthearticle.Ineachpassage,thereareoneortwoquestions.Whenstudentsfinishthesequestions,theywillfindthatthestructureofthetexthasturnedup.绅薮疮颧訝标販繯轅赛。T:Wonderful!Homeworkcheckisover.Inthelasttwoperiodswetalkedaboutagriculture.Aspeople’slivingconditionimproves,moreandmorepeopleareconcernedaboutwhattheyeat.Infactmoreandmorepeoplebecomeworriedaboutthequalityofthefoodtheyeat.Becausemoreandmorefarmersusechemicalfertilizerinsteadofnaturalwastefromanimalsandtheyusepoisontokillinsectstoprotecttheirplants.Sopeoplenowallwanttoeatgreenfoodwhichdoesnoharmtotheirhealth.Theyaremoreconcernedaboutorganicfarming.Nowlet’sreadthetext22/22\nandknowsomethingaboutorganicfarming.饪箩狞屬诺釙诬苧径凛。Task1:Questionsaboutthetext.Showthequestionsonthescreen:1.Whatistheorganicfarming?2.Whatistheadvantageofusingnaturalfertilizer?3.Whatisthedisadvantageofusingchemicalfertilizers?4.What’sthemainideaofparagraph3?5.Whydofarmersgrowtheircropsinsuchways?T:Boysandgirls,todaywe’llreadthetextoneparagraphbyoneparagraph.Nowpleasereadthefirstparagraphquickly,andfindtheanswertothefirstquestion:whatistheorganicfarming?烴毙潜籬賢擔視蠶贲粵。S1:Organicfarmingreferstocropsgrowingwithnaturalratherthanchemicalfertilizers.鋝岂涛軌跃轮莳講嫗键。T:Good.Nowreadthesecondparagraphquicklyandfindtheanswertothisquestion:whataretheadvantageofusingnaturalfertilizer?撷伪氢鱧轍幂聹諛詼庞。S2:Makethesoilricherinmineralsandsomorefertile.踪飯梦掺钓貞绫賁发蘄。T:anythingelse?S3:Reducediseasesincropsandhelpthemgrowstrongandhealthy.Besides,keeptheair,soilandwateraswellasthefoodsupplyfreefromchemical.婭鑠机职銦夾簣軒蚀骞。T:Whatisthedisadvantageofusingchemicalfertilizers?譽諶掺铒锭试监鄺儕泻。S4:Letmeanswerit.Therearethreedisadvantages.Firstly,leavingchemicalsinthegroundforalongtimeisnotgoodforthesoilorthewatersupply.Secondly,farmersoftengrowthesamecropyearafteryear.Asaresult,thesoilgetsexhausted.Thirdly,chemicalfertilizerskillbothhelpfulandharmfulbacteriaandpests.俦聹执償閏号燴鈿膽賾。MainideaofthepassageChemicalfertilizerscancausemanyproblems,soorganicfarmingisbecoming缜電怅淺靓蠐浅錒鵬凜。22/22\nmorepopular.1kejian.comStructureofthetextIusingchemicalfertilizersforalongtimecanhurtthelandandalsopeople’shealth骥擯帜褸饜兗椏長绛粤。IIProblemcausedbychemicalfertilizers1.Damagethelandbykillingthehelpfulbacteriaandpestsaswellastheharmfulones癱噴导閽骋艳捣靨骢鍵。2.Leadtocancerorotherillness.3.Foodgrownwithchemicalfertilizerslookbeautiful,butinsidethereisusuallymorewaterthanvitaminsandminerals.鑣鸽夺圆鯢齙慫餞離龐。ⅢOrganicfarmingisbecomingmorepopularwithsomefarmersandmanycustomersafterthesediscoveriescameout.榄阈团皱鹏緦寿驏頦蕴。IVOthermethodstokeepthesoilfertile.附件1Isorganicfoodsafe?Yes.Organicfoodisassafetoconsumeasanyotherkindoffood.Justaswithanykindofproduce,consumersshouldwashbeforeconsumingtoensuremaximumcleanliness.Ascitedabove,organicproducecontainssignificantlylowerlevelsofpesticideresiduesthanconventionalproduce.ItisacommonmisconceptionthatorganicfoodcouldbeatgreaterriskofE.colicontamin
