。2．強調(diào)句型要注意和it代表時間、距離、溫度、自然現(xiàn)象、詳細事物或人物等時所構(gòu)成的多種句型的區(qū)別Itwasat8o’clockthathearrivedhome.他是八點到家的。Itwas8o’clockwhenhearrivedhome.他到家時八點了。3．強調(diào)句型不能強調(diào)謂語，如需強調(diào)謂語，用do/does/did+動詞原形Hedidwritetoyoulastweek.他上星期確實給你寫信了。Idobelievethatheisanhonestman.我確實相信他是誠實人。4．強調(diào)句型與定語從句、主語從句、賓語從句、狀語從句結(jié)合在壹起Itwasattheschoolthat/whichwasnamedaftertheherothathespenthischildhood.他是在那因此英雄命名的學校度過了他的童年。用強調(diào)構(gòu)造對劃線部分進行強調(diào)1．NancysawyoursisterinTokyolastweek.(1)ItwasNancythat/who/whomsawyoursisterinTokyolastweek.(強調(diào)主語)(2)Itwasyoursisterthat/whoNancysawinTokyolastweek.(強調(diào)賓語)(3)ItwasinTokyothatNancysawyoursisterlastweek.(強調(diào)地點狀語)(4)ItwaslastweekthatNancysawyoursisterinTokyo.(強調(diào)時間狀語)2．Howdidyouforgettolockthedoor?Howwasitthatyouforgottolockthedoor?3．Ididn’thearfromheruntillastsummer.ItwasnotuntillastsummerthatIheardfromher.5.注意這種句型What+從句+is/was…是名詞從句構(gòu)造，也是壹種強調(diào)手段，常用來強調(diào)主語、賓語。所論述的是目前或者未來發(fā)生的事情What+從句is…所論述的是過去發(fā)生的事情What+從句was…Whathewishesmostistobecomeapilot.他最但愿的是成為壹名飛行員。（強調(diào)賓語）Whatinterestedmemostwasthebeautifulscenery.使我最感愛好的是那漂亮的風景。（強調(diào)主語）判斷與否是強調(diào)句，可把Itis/was…that去掉，剩余部分在不增減任何詞的狀況下還是壹種完整的句子，那么這種句子是強調(diào)句。小結(jié)：Itis/was+被強調(diào)部分+that+剩余的部分被強調(diào)部分是人who/whom/that+剩余的部分注意(被強調(diào)部分是:主語，賓語，表語或狀語)跟蹤練習1.選出最恰當?shù)拇鸢?.Itwas___hesaid____disappointedme.A.what;thatB.that;thatC.what;whatD.that;what2.Isitinthefactory_____thistypeofcarsareproduced?A.whichB.whereC.thatD./3.Isitthefactory______thistypeofcarsareproduced?A.whichB.whereC.thatD./4._____onMondaynightthatallthishappened?A.IsitB.ItisC.WasitD.Itwas5.Itwas_____theoldworkercamethatwe_____theexperiment.A.until;didn’tbeginB.notuntil;beganC.untilbeganD.notuntil;didn’tbegin6.ItisI____singinginthegarden.A.whoareB.whoisC.thatamD.thatis7.---Whydidn’tyouanswerwhenIspoketoyouinthestreetthismorning?---I___butyoudidn’thearme.A.didanswerB.didn’twanttoanswerC.couldn’tanswerD.wastoobusy8.ItisinthewestofChina_____thereisnodoubt_____itisgoingtoraintomorrow.A.where;whetherB.that;thatC.that;whetherD.where;that9.Itwas1969___theAmericanastronautssucceededinlandingonthemoon.A.thatB.whenC.onwhichD.which2對下列各句中的劃線部分進行強調(diào)1．SusanandJohnwereabsentfromschoolyesterday.__________________________________________________________________________2．Hewasn’tabletogobacktohismotherlanduntilthewarwasover.__________________________________________________________________________3．TheoldladywaslookingforaChinesedictionary.__________________________________________________________________________4．Whendidyoureceivethegift?__________________________________________________________________________5．DidtheprofessorgraduatefromShandongUniversityin1968?_______________________________________________________________________用合適的連接詞填空1．Itwaswhenwewerereturninghome____________Irealizedwhatagoodfeelingitwastohavehelpedsomeoneintrouble.(·湖南)2．Bachdiedin1750，but____________wasnotuntiltheearly19thcenturythathismusicalgiftwasfullyrecognized.(·重慶)3．It’snotdoingthethingswelike，butlikingthethingswehavetodo____________makeslifehappy.(·湖南)4．Itwasthemiddleofthenight____________myfatherwokemeupandtoldmetowatchthefootballgame.(·江西)5．Itwastheculture，ratherthanthelanguage，____________madeithardforhimtoadapttothenewenvironmentabroad.(·福建)6．WasitbecauseJackcamelateforschool____________Mr.Smithgotangry？(·四川)7．Itwasonlyafterhehadreadthepapers____________Mr.Grossrealizedthetaskbeforehimwasextremelydifficulttocomplete.(·全國新課標Ⅱ)8．Itwasnotuntilneartheendoftheletter____________shementionedherownplan.(·天津)9．Itwaswiththehelpofthelocalguide____________themountainclimberwasrescued.(·重慶)UsinglanguageWhatcanwedoaboutglobalwarming?學習目的Learninggoals:學習有關(guān)全球變暖的知識：起因，影響，對策等。學會使用有關(guān)全球變暖的有關(guān)體現(xiàn)，提高閱讀能力和語言的實際運用能力。課前自主學習：1.TranslatethefollowingwordsandexpressionsintoChinese.1.greenhousen.2.catastrophe.n.3.pollution.n.4.individualn.5.commitmentn.6.electrical.adj.7.appliance.n.8.motor.n.9.circumstance.n.10.microwave.n.11contribution.n.12.adovate.v.13.onbehalfof14.putupwith.15.solongas.2.Thinkaboutthesequestionsandfinishtheseblanksusingthegivenwords.1.Whatisagreenhouse?Agreenhouseismadeofandisusedforgrowing,especiallyduringweather.Theairinsideisbecausetheglasstrapsthe______fromthesunandkeepsitfromescaping.Thismakesthegreenhouseheatupandsotheplantscangrowthecoldperiod.(plantsthroughoutglassheatwarmcold)3.Fastreading:Skimthetextandanswerthefollowingquestions.(10minutes)1.Thefirstletteriswrittenby()A.ateacherB.aeditorC.astudentC.avolunteer2.Thepurposeofthefirstletteris()A.totellussomeknowledgeofglobalwarming.B.totellusweshouldprotectenvironment.C.toasksomesuggestionsforaproject—globalwarming.D.totelltheeditorthathedoesn’tknowwhattodoaboutglobalwarming.3.Whatisthemainideaofthesecondletter?
