WordsandexpressionsUnit3Underthesea1.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。unit3Wordsandexpressions2.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.Witness①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?witness②witness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.witnessed③witness还可以用作名词，表示“目击者”、“证人”，她被传唤作被告证人。Shewascalledasa______________.defensewitness④beawitnessto….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.opposite…adj.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.⑴Hekilledhisenemyand_______________.fleefrom逃离某地,逃脱=escapefrom=runawayfrom翻译:他们从着火的房子里逃出来了.⑵Theyfledfromtheburninghouse.fledthecountry7draggeddrag:pullsb./sthalongwithefforteg.Hedraggedthetableintothecorner•dragdown把人拖垮•dragone’sfeet故意拖延•dragin拉进去•dragon拖延，拉长8.Depths表示底层，深处•Thedepthsoftheocean•Thedepthsofthejungle•Thedepthsofthecountry•Thedepthsofwinter•Thedepthsofone’sheart•Thedepthsofdespair•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_________.inlengthinwidth2.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anurgetodosth10reflect(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reflectingreflected11.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.poorA12.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.narrown.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,weshouldn’tlethimdothegreattask.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upsidedowninsideoutinsideout反了的，里外颠倒(1)Thereisacaraccident.Thecaris_________upsidedown16.…sucking..suckone’steeth啧啧的不胜羡慕suckknowledgeintoone’smind吸收知识17.sharp…sharp.adj锋利的，锐利的e.g.Hecutthewatermelonintwowithasharpknife.1.Mygrandfatherisnearly70yearsold,buthismindisstillsharp.2.Herstepmother’sharpwordshurtherdeeply.3.Therewasasharpriseinthepriceoffoodrecently.4.Themeetingstartsatthreeo’clocksharp.敏捷的刻薄的急剧的整点的18.tasty(adj.)“好吃的,可口的”=delicious→taste(v.＆n.)“吃，品尝,尝起来,味道”1)Thisisa________meal.2)Thecake_________sweet,becauseithasasweet___________.3)Thepatient_______________fortwodays.tastytastestastehasn’ttasted19.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.withB20.shallowshallow浅的，肤浅的，浅显的2）Hispaperweren’tpublished,foritwasrathershallow.注意：深、浅深度深浅：deepshallow颜色深浅：darklight1）ThewaterinPictureoneis_____whilethewaterinPictureTwoisdeep.shallow21.boundaryn.界限；分界线e.g.Thelineistheboundaryofplayground辨析：“边界”boundary，borderboundary：主要指山，河流等形成的天然边界线，多指地图上的领土分界线。border主要指“边境得带”范围较广的地区。e.g.Thatriveristheboundaryofourland.Theyhadarrivedtheborderbetweenthetwocountries..
