AcuckoointhenestUnit17(Lesson33)鸟窝中的布谷鸟swallow[ˈswɔləu]燕子magpie[ˈmægˌpaɪ]喜鹊sparrow[ˈspærəʊ]麻雀eagle[ˈi:ɡl]鹰cuckoocuckoo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08年奥运会是在哪里举行的？鸟巢nest[nest]n.鸟窝，鸟巢Acuckoointhenest['kuku:]theBird'sNestbirdwatcher观鸟者engineer工程师webcam网络摄像机NewWordsandExpressionscuckoo['kʊku:]n.杜鹃，布谷鸟nest[nest]n.鸟窝，巢engineer[ˌendʒɪ'nɪə]n.工程师enthusiastic[ɪnˌθju:ziˈæstɪk]adj.很感兴趣的birdwatchern.观鸟者appear[ə'pɪə]v.出现install[ɪnˈstɔ:l]v.安装•enthusiasticabout〔for,over〕对…热心•enthusiasticin在…热心•appearatsth1.在(某时或某处)出现,显露arriveatThestarsappearatnight.•星星在晚上出现。Sheappearspromptlyateighteachday.•她每天8点准时到。appearto看来像是appeartobe好象是•2.出庭;演出•ThetwothieveswillappearatNewStreetCourttomorrowmorning.那两名盗窃犯明日上午将在新街法院出庭受审。•ThefamousactorisnowappearingattheGrandTheatre.那位著名演员目前正在格兰德剧院演出。appearas作为...出现appearin出现在...appear----disappear消失•appearbeforesb/sth1.(在某时或某人之前)出现•Theyappearedbeforeus.他们出现在我们面前。•2.出庭•Heappearedbeforethejudgeincourtyesterdayonacartheftcharge.有人控告他偷汽车,昨天他出庭受审了。install•installas使就任为•installoneselfaschairmanof•就任…的主席•installsbaspresident使某人就任主席•install...in把…放到…里,就任•installoneselfinachair坐在椅子上•installoneselfinone'snewoffice就任新职•install...to把…装到…上webcam[ˈwebkæm]n.网络摄像机(=webcamera)invite[ɪn'vaɪt]v.邀请logonv.+adv.登录enthusiastically[ɪnˌθju:zɪ'æstɪklɪ]adv.(manner)很感兴趣地patiently['peɪʃntli]adv.(manner)耐心地egg[eɡ]n.蛋suddenly[ˈsʌdənli]adv.(time)(manner)突然地invite•invitesbforsth为…而邀请•Weinvitedthemtoourplaceforadrink.•我们请他们到我们家来喝一杯。•invitesbin请(某人)进入(房间、房屋等)•Theyinvitemein.他们邀请我进屋。•invitesbout(to)请(某人)出去•Theyinvitedusouttodinner.•他们邀请我们出去吃饭。•inviteover请(某人)过来•Weinvitehimover.我们请他过来。•invitesboverforsthHeinvitedhisfriendoverforatalkafterwork.他请他的朋友下班后来谈谈。•invitesbto邀请(某人)参加•Sheinvitedmetoherbirthdayparty.•她邀请我参加她的生日宴会。chance[tʃɑ:ns]n.机会dart[dɑ:t]v.急冲second['sekənd]n.（时间的）秒hatch[hætʃ]v.破壳而出，孵出excitedly[ik'saitidli]adv.(manner)激动地，兴奋地easily['iːzɪlɪ]adv.(manner)容易地chance•awaitachance等待机会•getachance得到机会•graspachance抓住机会•haveachance有机会•havenochance(of)没有(…的)可能•letthechancego放过机会•loseachance失去机会•missachance错过机会•tryone'schance试一试运气•waitforachance等待机会•givesbachance给某人机会•bychance偶然,碰巧•chancefor/ofsuccess成功的机会dart•dartaway/off/forward飞奔而逃•dartinto冲进•dartthrough掠过•dartthroughtheair划破天空•darttoone'sfeet一跃而起hatch•hatchout孵出,得出结果•hatchsthfromsth从…中孵出…•tohatcheggspush[pʊʃ]v.推，推动outofprep.外enormous[ɪ'nɔːməs]adj.巨大的，极大wing[wɪŋ]n.翅膀，翼inamomentadv.(time)片刻，瞬间show[ʃəʊ]n.演出beoverv.+adv.particle(intransitive)结束enormous,huge,immense,massive,vast•这组词的共同意思是“大的”。•huge指超越一定标准大的事物的体积或容量,用在比喻中形容抽象事物,指某事严重或急需解决;•enormous指“大”到令人吃惊、甚至不相称的程度,也常形容抽象事物的严肃性、迫切性;•immense不强调重量,只强调体积、数量或程度等超过一般标准;•massive通常指大而重的物体,但也修饰抽象的概念如力量、结果等;•vast用以指范围、数量,但着重指面积,而不涉及重量或体积。push•pushaway推开•pushback推迟•pushdown推倒某物•pushin推入,塞入•pushwayin挤进•pushoff离开,动身,出发•pushagainst推•pushatthedoorbell按门铃show•attendashow看演出•giveashow上演•gotoashow去看展览〔演出,电影〕•holdashow举办展览•makeashow展示•talkshow答问节目•filmshow电影展engineerwebcamappearinstallWhat’smissing?eggenthusiasticChancedartsuddenlyexcitedlyWhichismissing?easilypatientlyenomouswingWhichismissing?pushoutofshowlogonbeoverWhichismissing?inamomentListeningandunderstanding•Listentotherecording,andthenanswerthisquestion:•Whoareallenthusiasticbirdwatchersnow?1.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Let’sdoGuidedConversationonpage13.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’sneighboursareent
