高中英语 Unit 3 Under the sea period2 vocabulary课件 新人教版选修7.pptVIP

Wordsandexpressions,Unit3Underthesea,1.学生能够了解本单元单词的基本用法。2.学生能够辨析易混淆词的用法，并能熟练运用。3.学生能够掌握重点难点词的拓展及其用法。,本节课为unit3的单词和短语教学，单词本来是零散的，易混的，但是本节课运用了从点到线，从线到面的词汇教学方法，使重点难点单词成了容易掌握的单词块，单词串，从而实现了知识即词汇的重新组合，这一点也符合新的英语教学大纲的要求。首先，用听本单元的单词录音进行导入，让学生从整体上感知下单词。然后，对重点单词进行讲解，既有对单词用法的拓展，又有对短语释义的延伸。讲解和巩固练习结合，让学生加深理解词汇用法并当堂掌握。而且，练习形式多样化，有翻译，有填空，有选择，从各个角度来对词汇关进行突破。,2.annualannualadj./n.每年的,一年一次的,年刊,年鉴anannualevent一年一度的活动anannualreport年度报告annualring年轮annually年年地,每年地,2.Witness用作动词，意思是“亲眼看到”，如:你亲眼看到那场事故了吗？Didyou_theaccident?,witness,witness还可表示“作证”、“证明”，常用“witnesstosth/doingsth”例如：,他作证说他看到那个人进入大楼的.He_tohavingseenthemanenterthebuilding.,witnessed,witness还可以用作名词，表示“目击者”、“证人”，她被传唤作被告证人。Shewascalledasa_.,defensewitness,beawitnessto.是的目击者bear/givewitnesstosth为作证,3.accommodation.1)房间，住所2)lodgings,roomsandfood膳宿（在英英中为不可数，在美英中为可数，常用复数）accommodatev.accommodatingadj.accommodatorn.,适应，调节,亲切的，易打交道的,调节者,4.oppositeadj.相反的;对立的;对面的;相对的(常与to,from连用)n.相反的人或物prep.在.的对面辨析:opposite,contraryopposite指位置,方向,地位,性质,意义等对立的,相反的,”e.g.“Trueandfalse”havetheoppositemeaning.contrary指“两物朝相反的方向发展”,含有“互相冲突,不一致”的意思.eg.Yourplaniscontrarytomine.,5.teamworkteamn.队,组vi.协同工作teammaten.队友,6.flee(fled,fled)vt.逃避,逃跑,逃走vi.消散,逃,消失他杀死了仇敌,逃往了国外.Hekilledhisenemyand_.fleefrom逃离某地,逃脱=escapefrom=runawayfrom翻译:他们从着火的房子里逃出来了.Theyfledfromtheburninghouse.,fledthecountry,7draggeddrag:pullsb./sthalongwithefforteg.Hedraggedthetableintothecornerdragdown把人拖垮dragonesfeet故意拖延dragin拉进去dragon拖延，拉长,8.Depths表示底层，深处ThedepthsoftheoceanThedepthsofthejungleThedepthsofthecountryThedepthsofwinterThedepthsofonesheartThedepthsofdespair,海洋深处丛林深处穷乡僻壤隆冬心灵深处绝望的深渊,注意,1.Theriveris5mileslongand2meterswide.=Theriveris5miles_and2meters_.,in,length,in,width,2.deep(adj.adv.)“深的,深,迟”,指具体深度.deeply(adv.)“深深地”,带有感情色彩.,9.urgedurgesbtodosth催促/怂恿某人做某事urgeitsimportance强调其重要性n.迫切要求;强烈的欲望anurgetodosth,10reflect(vt.vi.)反射,映射,思考1)After_foratime,hedecidednottogothere.2)Themountains_inthelakewereverybeautiful.reflecton(upon)仔细考虑,思考我要思考一下下一步该怎么做.Iwillreflectonwhattodonextonreflection再三考虑,reflecting,reflected,11.pure.adj.纯粹的，无垢的，清白的e.g.1)Thesweaterismadeofpurewool.2)Theairintheforestispurerandcleanerthanthatinthecity.短语:pureandsimple完完全全的，十足的By_coincidencewemetinBeijingforthesecondtime.A.pureB.purityC.throughD.poor,A,12.be/become(well)awareof/that对知道，明白；意识到我希望在情况影响你前,你能察觉到。Iwantyoutobeawareofthesituationbeforeitaffectsyou.我很清楚他就是我要求助的人。IamwellawarethatheistheoneIshouldturnto.,13neatneatadj.整齐的，匀称的，好的（口语）e.g.Ourclassroomisalwaysneat.辨析：neat，clean二者都表示“整洁的”区别在于：neat：侧重整齐的clean:侧重干净的e.g.Shekeepherdeskneat.Theschoolisveryclean.,14.narrow,n.狭窄部分,海峡,隘路a.狭窄的,精密的,有限的,勉强的,眼光短浅的Theyhadtowormtheirwaythroughthenarrowtunnel.他们得钻过狭窄的隧道.Hewasnarrow-minded,weshouldntlethimdothegreattask.短语：anarrowescape九死一生inanarrowsense在狭义上,15.upsidedown(2)Theofficeisbeingdecorated,soeverythingis_.e.g.LookatJack.Hisjacketis_.,上下翻转的；颠倒的；乱七八糟的,upsidedown,insideout,insideout,反了的，里外颠倒,(1)Thereisacaraccident.Thecaris_,upsidedown,16.sucking.suckonesteeth啧啧的不胜羡慕suckknowledgeintoonesmind吸收知识,17.sharpsharp.adj锋利的，锐利的e.g.Hecutthewatermelonintwowithasharpknife.1.Mygrandfatherisnearly70yearsold,buthismindisstillsharp.2.Herstepmothersharpwordshurtherdeeply.3.Therewasasharpriseinthepriceoffoodrecently.4.Themeetingstartsatthreeoclocksharp.,敏捷的,刻薄的,急剧的,整点的,18.tasty(adj.)“好吃的,可口的”=delicioustaste(v.n.)“吃，品尝,尝起来,味道”Thisisa_meal.2)Thecake_sweet,becauseithasasweet_.Thepatient_fortwodays.,tasty,tastes,taste,hasnttasted,19.scaredtodeathscaretodeath吓坏了，吓得要死starvetodeath饿死beatsbtodeath打死某人sentencesbtodeath判某人死刑betiredtodeath累极了beboredtodeath烦透了workoneselftodeath积劳而死,注意：scaretodeath中介词to表示到达某种结果。类似的，Myincomethismonthhasamountedto5000dollars.Shetorethelettertopieces.Thetrainslowedtoastop.,WhenMaryheardthestoryofthehero,shewasmoved_tears.A.atB.toC.byD.with,B,20.shallowshallow浅的，肤浅的，浅显的2）Hispaperwerentpublished,foritwasrathershallow.注意：深、浅深度深浅：deepshallow颜色深浅：darklight,1）ThewaterinPictureoneis_whilethewaterinPictureTwoisdeep.,shallow,21.boundaryn.界限；分界线e.g.
