Unit17Acuckoointhenestlead-in动物界的十大坏妈妈:布谷鸟cuckoo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。lesson33Let'slearnsomenewwordsandexpressions: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Lesson33nestThere’rethreecolorfuleggsinthisnest.theBirdNestinBeijingLesson33engineer[,endʒi'niə]Lesson33birdwatcherLesson33appear----disappear消失eg.Youappearunhappy.Threelittleeggsappearedinthenest.Lesson33enthusiastic[in,θju:zi‘æstik]enthusiasticallyadv.热情地beenthusiasticto对……热情的eg.PeopleareenthusiastictoSpringFestival.He’sanenthusiasticbirdwatcher.Everyonewatchedenthusiastically.Lesson33webcameg.Sheinstalledawebcam.Lesson33installeg.Theworkersareinstallinganair-conditioner.(空调)Lesson33logonLesson33eggLesson33inviteinvitesb.todosth.邀请某人做某事eg.Weinvitedallthefriendstogotothebirthdayparty.Keninstalledawebcam,andinvitedhisneighbourstologon.invitationn.邀请Lesson33hatchLesson31patientlypatientn.病人easilyeasyadj.容易的suddenlysuddenadj.突然的excitedlyexcitedadj.（使人）兴奋的excitingadj.（令人）兴奋的Lesson33enormouseg.Shestoodaloneontheenormousstage.近义词big大的huge巨大的large大的反义词small小的tiny极小的Lesson33wingLesson33showLesson33Listentotherecording,andthenanswerthisquestion:Whoareallenthusiasticbirdwatchersnow?Lesson331.Acuckoointhenest.在此处指这个故事，但也是一个习语，指一个人不属于某地或者不受欢迎，却偏偏利用这个地方。2.Paul’sfather,KenBruceisanengineer.He’salsoanenthusiasticbirdwatcher.3.Then,anotherbirdarrived.Intwoseconds,therewasafourtheggbesidetheotherthree.4.Thelittlebirdshurriedtogetfoodforthebabycuckoo.hurry的过去式是hurriedget+名词/代词=obtain5.Thebabycuckoopickeduptheothereggseasilywithitsback,andpushedthemoutofthenest.with=bymeansof用6.Theshowwasover.over=atanend/finished结束Lesson34NewWordsandExpressions:robbern.盗贼countv.数quicklyadv.(manner)迅速地dancen.社交舞会politelyadv.(manner)有礼貌地policen.警方、警察carefullyadv.(manner)小心地quietlyadv.(manner)安静地badlyadv.(manner)不好地，差地weightn.重物knockv.敲击loudlyadv.(manner)大声地pianon.钢琴thewhole(+sinularn.)quantifier所有的betweenprep.在…之间Lesson34quickly——quickpolitely——politepatiently——patientquietly——quietbadly——badexcitedly——excitedloudly——loudcarefully——carefuleasily——easyLesson341.quietly反义词noisily喧闹地2.badly反义词well很好地3.弹钢琴playthepiano踢足球playfootball4.thewhole后面跟单数5.between：两者之间among：三者及以上betweenAandB.6.pickupsomeweightsatthegym7.knockonthedoorPatternPractice1.A:Whatdidtherobbersdolatelastnight?B:Theycountedthemoney.PatternPractice2.A:Whocountedthemoneylatelastnight?B:Therobbersdid.PatternPractice3.A:Didtherobberscountthemoneylatelastnight?B:Yes,theydid.Theycountedthemoneyquickly.PatternPractice4.(Notwithpicture505)A:Whendidtherobberscountthemoney?B:Latelastnight.A:Anddidtheycountthemoneyquickly?B:Yes,theydid.PatternPractice5.A:Therobberscountedthemoneylatelastnight.B:Yes,Iknow.Theycountedthemoneyquickly.Lesson34Homework做测试卷谢谢！放映结束感谢各位的批评指导！让我们共同进步知识回顾KnowledgeReview
