AcuckoointhenestUnit17(Lesson33)鸟窝中的布谷鸟Acuckoointhenest['kuku:]布谷鸟准备产蛋了，但它却不会自己筑巢,它会来到像那些比它小的鸟类的巢中，移走原来的那窝蛋中的一个，用自己的蛋来取而代之。相对于它的体形来说，它的蛋是偏小的，而且蛋上的斑纹同它混入的其他鸟的蛋也非常相似，所以不易被分辨出来。如果不是这样，它的蛋肯定会被扔出去。布谷鸟的鸟蛋比其他鸟蛋早孵化。幼鸟出来后，会立刻把其他的蛋扔出巢外。它之所以这样做，是因为它不久就会长得很大，需要吃光养母所能找到的全部食物。一只布谷鸟的幼鸟正在由它的养母----一只比它小得多的刺嘴莺喂食。它需要的食物相当于3---4只其养母亲生的幼鸟本来需要进食的总量。趁其他鸟没看见时，布谷鸟在它们的巢中产蛋。它必须非常迅速地做完这件事。它的蛋有着特别厚的外壳，这样在落入巢中时就不会碎掉了。动物界的十大坏妈妈:布谷鸟NewWordsandExpressions:cuckoon.杜鹃，布谷鸟nestn.鸟窝，巢engineern.工程师enthusiasticadj.很感兴趣的birdwatchern.观鸟者appearv.出现installv.安装webcamn.网络摄像机invitev.邀请logonv.+adv.登录enthusiasticallyadv.(manner)很感兴趣地patientlyadv.(manner)耐心地eggn.蛋suddenlyadv.(time)(manner)突然地chancen.机会dartv.急冲secondn.（时间的）秒hatchv.破壳而出，孵出excitedlyadv.(manner)激动地，兴奋地easilyadv.(manner)容易地pushv.推，推动outofprep.外enormousadj.巨大的，极大wingn.翅膀，翼inamomentadv.(time)片刻，瞬间shown.演出beoverv.+adv.particle(intransitive)结束•nest[nest]n.鸟窝，鸟巢theBird'sNestbirdwatcher观鸟者engineer[,endʒi'niə]工程师•enthusiastic[in,θju:zi‘æstik]adj.狂热的，满腔热情的；很感兴趣的•enthusiastically[in,θju:zi'æstikəli]adv.很感兴趣地；满腔热情地e.g.Everyonewatchedenthusiastically.webcam网络摄像机hatch[hætʃ]vt.孵出，破壳而出tohatcheggsappear----disappear消失vi.出现；出版；显得；好像1.Ashipappearedonthehorizon.船出现在水平线上。2.Youappearunhappy.你看起来好像不高兴。appearas作为...出现appearin出现在...appearto看来像是appeartobe好象是installv.安装•1.Sheinstalledanair-conditionerbyherself.她自己安装了空调。•2.Theworkersareinstallingaheatingsystem.工人们正在安装供暖系统。译：安装一个摄像头•webcamn.网络摄像头(=webcamera)invite•vt.邀请；请求；招致；招待•Invitesb.todosth.邀请某人做某事•1.Weinvitedalltherelativestothewedding.我们邀请了所有的亲戚来参加婚礼。•2.Heisinvitinghisfriendtodinner.他正在招待朋友吃饭。patientlyadv.耐心地1.Heansweredmyquestionspatiently.他耐心地回答我的问题。2.Hewasangry,buthelistenedtomepatiently.他很生气，但他还是耐心听我讲。n.病人，患者-----patientsuddenlyadv.突然地1.Suddenlyhebegantoshriekloudly.突然他开始大声尖叫起来。2.Thecarstoppedsuddenly.汽车突然停下了。excitedly•adv.激动地；兴奋地•1.Heexcitedlytalkedaboutsomething.他激动地在说着什么。•2.Thedogwaggeditstailexcitedly.那条狗兴奋地直摇尾巴。easily•adv.容易地；•1.Weeasilyclimbeddownthesideofthecliff.•我们很容易地从悬崖边上爬下来了。•2.Wecrossedthatbrookeasily.•我们很容易地跨过了小河。enormousadj.巨大的；庞大的1.Longagoenormousanimalslivedontheearth.•很久以前，地球上生活着巨大的动物。•2.Shestoodaloneontheenormousstage.•她孤零零地站在巨大的舞台上。•近义词•big大的huge巨大的large大的•【反义词】•small小的tiny极小的wing••n.翅膀；Thebird'sleftwingwashurt.•这只鸟的左翼受伤了。inamoment•立即；马上；转瞬•Ireallymustgohomeinamoment.•我得马上回家了。engineerwebcamappearinstallWhat’smissing?eggenthusiasticChancedartsuddenlyexcitedlyWhichismissing?easilypatientlyenomouswingWhichismissing?pushOutofshowLogonBeoverWhichismissing?Inamoment1.Paul’sfather,KenBruceisanengineer.He’salsoanenthusiasticbirdwatcher.Lastspring,twolittlebirdsappearedinhisgarden.Keninstalledawebcam,andinvitedhisneighbourstologon.Everyonewatchedenthusiastically.Soon,therewasalittlenest.Then,anotherbirdarrived.Itwasacuckoo.Thecuckoowatchedpatiently.Threelittleeggsappearedinthenest.invitesb.todosth.2.Thecuckoowaited.Suddenly,shehadherchance.Themotherwasn’tthere.Thecuckoodartedtothenest.Intwoseconds,therewasafourtheggbesidetheotherthree.她的机会来了。3.4.Aftertwelvedays,theyoungcuckoohatched.Thelittlebirdshurriedtogetfoodforthebabycuckoo.“get”+名词/代词，表“得到”==obtain5.Ken’sneighbourswatchedexcitedly.Thebabycuckoopickeduptheothereggseasilywithitsback,andpushedthemoutofthenest.Thebirdsreturnedandpushedfoodintoitsmouth.Aftertwentydays,thecuckoowasenormous!On6thMay,itopeneditswings.Inamoment,thenestwasempty.Theshowwasover.==bymeansof用……finished6.Ken’sneighboursareallenthusiasticbirdwatchersnow,ofcourse!用在动词后修饰主语Retellthetext:(Picture1—6)Paul’sfather,KenBruceis.He’salso.Lastspring,twolittlebirdsinhis.Kenandhisneighboursto.Everyonewatched.Soon,alittle.Then,anotherbirdarrived.Itwasa.Thecuckoowatched.Threelittleeggsappearedinthenest.Thecuckoowaited.,she.Themotherthere.Thecuckootothenest.Intwoseconds,therewasaeggbesidethree.Aftertwelvedays,theyoungcuckoo.Thelittlebirdsgetfoodthebabycuckoo.Ken’sneighbourswatched.Thebabycuckootheothereggseasilyitsback,andthemthenest.Thebirdsandfooditsmouth.Aftertwentydays,thecuckoowas!On6thMay,ititswings.Inamoment,thenestwas.Theshowwas.Ken’sneighboursareenthusiasticbirdwatchersnow,ofcourse!Lesson34Pronunciation’dartedin’vitedreco’mmended’visited’waited’counted/Id/NewWordsandExpressionsrobbern.盗贼badlyadv.不好地，差地countv.数weightn.重物quicklyadv.迅速地knockv.敲击dancen.社交舞会loudlyadv.大声地politelyadv.有礼貌地pianon.钢琴policen.警方、警察thewhole所有的carefullyadv.小心地betweenprep.在…之间quietlyadv.安静地•Robbern.盗贼；强盗。Therobbertiedhimtoadesk.强盗把他捆在桌子上。Therobberscountedthemoneyquicklylastnight.这些盗贼昨晚飞快的数了钱。quietly安静地；悄悄地；•1.Thebabyissleepingquietly.•那婴儿一直安静地睡着。•3.Hepassedquietlyoutoftheroom.•他悄悄地走出房间。•【反义词】noisily喧闹地badly.差的；不好的•1.Thefirmdidbadlylastyear.•公司去年生意不好。•【反义词】•well很好地•规则动词过去式加“ed”后的发音规则•清辅音：送气强，声带不振动。•浊辅音：几乎不送气，声带振动。（送气指从喉咙向口外送出气流）•（1）清辅音：／p／、／t／、／k／、／f／、／θ／、／s／、／W／、／t∫／、／ts／、／tr／，再加上／r／、／h／，合计12个。（2）浊辅音：／b／、／d／、／g／、／v／、／ð／、／z／、／3／、／d3／、／dz／、／dr／再加上／m／、／n／、／η／、／l／、／j／、／w／合计16个。在浊辅音和元音后面[d]calledborrowedmoved[mu:vd]welcomedanswered在清辅音后面[t]askedfinishedhelped[helpt]passed[pa:st]reached在[t]音后面[id]wanted['wCntid]started['sta:tid][d]音后面[id]needed['ni:did]counted['kauntid
