今天就来探索这处奇妙的奇观吧！Planyourtripandexplorethebeautyof… 计划你的旅行，探索……的美。3cWriteanadvertisementforQinghaiLakeoranothernaturalwonder.Trytomakeyouradvertisementaspersuasiveaspossible.While-writingPost-writingExchangeyourwritingswithyourpartnerstocheckeachother’swriting.ChecklistSelf-evaluationPeer-evaluationTeacher-evaluationClearpurposeSpecificdetailsNaturalflowRightlinkingwordsRightgrammar/spellingProperformatSinceretoneGreatGoodTryharderPost-writingQinghaiLake:AnAmazingHighlandWonderDoyoulovequietlakesandamazingwildlife?ThenvisitQinghaiLake!QinghaiLake,China'slargestlake,isamust-visit!Itisasaltlake.Covering4,340km,ithasamazingviews:bluewatermeetsthesky,surroundedbymountainsandgrasslands.Wildlifeloverswillbehappyhere.Youcanseemanyfish,birdsandfieldsofbloomingrapeflowers.Therearefunthingstodo,too.Rideabikeorhorse,orvisitpeacefulislands.Don'tmissthisnaturalwonder.ComeandenjoythebeautyofQinghaiLake!SamplePART.044a—4c(project)Designaposteraboutanaturalwonder4aWorkinagroup.Chooseanaturalwonder(ariver,lake,mountain,forest,waterfall,etc.).Thendosomeresearchandmakenotes.namelocationandsizeplantsandanimalsspecialfactsYoucandosomeresearchbytheseways:4bMakeaposteraboutthenaturalwonderyouchose.Refertotheexampleontheright.titlekeyinformationpicturesspecialfactssizelocationplantsandanimals4cAsagroup,giveareporttotheclass.Payattentiontotheuseoflargenumbers,comparatives,andsuperlatives.TheAmazonRainforestistheworld’sbiggestrainforest.Itcovers6millionsquarekilometres.Youcanseemostofitinthreecountries,Brazil,Peru,andColombia...SampleMountTaioneofChina’sFiveGreatMountainsincentralShandongProvinceabout250squarekilometresinsizeaUNESCOWorldHeritageSitefourWondersofMountTai—MountTaisunrise,seaofcloudsandJadePlate,sunsetglowandYellowRivergoldenbeltalotofoldtemplesandstonecarvingsMountTaiisoneofChina’sFiveGreatMountains.LocatedincentralShandongProvince,itcoversanareaofabout250squarekilometres,withitsmainpeak,JadeEmperorPeak,reachinganaltitude(海拔)of1,545metres.Itiswell-knownforitsbeautifulsceneryandlonghistory.MountTaihasbeenaUNESCOWorldHeritageSitesince1987.ThereareFourWondersofMountTai—MountTaisunrise,seaofcloudsandJadePlate,sunsetglowandYellowRivergoldenbelt.Everyyear,thousandsofvisitorscometowatchthesunrisefromthetop.Theviewisreallyamazing—youcanseethesunriseslowlyfromtheeast,paintingtheskyinorangeandred.MountTaialsohasalotofoldtemplesandstonecarvings(雕刻品).ThesethingstellusstoriesaboutancientChineseculture.Forexample,somecarvingsarefromover2,000yearsago!ClimbingMountTaiisagreatexperience.ItnotonlyletsyouenjoyniceviewsbutalsohelpsyoulearnaboutChinesehistory.Ifyouhaveachance,youshouldvisitit!SamplePART.05Reflecting1.Whatnewfactsaboutnaturalwondershaveyoulearnt?2.Canyoumakecomparisonswhentalkingaboutnaturalwonders?3.Canyouuselargenumberstogivesomegeographyfacts?4.Canyouexplainhowandwhypeopleconnectwithnature?5.Whataresomeachievementsthatpeoplehavemadewhileexploringnature?ReflectingPART.06LanguagePoints1.LocatedonthenortheasterncoastofAustralia,theGreatBarrierReefisoneofthemostamazingplacestovisit.大堡礁位于澳大利亚东北海岸，是最令人惊叹的游览胜地之一。onthecoast(of...)在（……）海岸上ManybeautifulcitiesareonthecoastofChina.许多美丽的城市都在中国沿海海岸上。alongthecoast沿海Therearemanywonderfulbeachesalongthecoast.沿海一带有很多很棒的海滩。本句中动词不定式tovisit作后置定语，修饰places。被修饰词places作动词visit的宾语。动词不定式（短语）作定语修饰名词时，通常放在名词的后面。如果动词不定式与所修饰的名词存在动宾关系，且构成不定式的动词是不及物动词，须加上相应的介词。Ihavealotofhomeworktodoeveryday.我每天有很多作业要做。Thelittlegirlhasnofriendstoplaywithafterschool.这个小女孩放学后没有朋友可以一起玩。2.Ittakesupanareaof345,000squarekilometresandincludesmanyislandsandwhitesandbeaches.它占地34.5万平方千米，包含多个岛屿和白色沙滩。include不用于进行时，其后可接名词、代词或动词-ing作宾语，不可接动词不定式。Myjobincludesansweringemailsandhelpingcustomers.我的工作包括回复邮件和帮助顾客。辨析included与includingEightpeoplecametotheparty,includingmylittlesister.八个人来参加了聚会，包括我的小妹妹。Eightpeoplecametotheparty,mylittlesisterincluded.八个人来参加了聚会，我的小妹妹也在内。included形容词包括在内的后跟名词或代词作宾语including介词包括……在内只能位于名词或代词后，作后置定语3.TheGreatBarrierReefisalsoalive!大堡礁也是充满生机的！comealive热闹起来；有精神起来Thepartybegantocomealivewhenmusicandsongsstarted.当音乐和歌声响起时，派对开始热闹起来。bringsth.alive使……有趣；变得有生气Agoodteachercanbringalessonaliveandmakestudentsinterestedinit.一位好老师能让课堂变得生动有趣，让学生爱上学习。辨析alive、living与livelyaliveadj.
