四级翻译一：泰山位于XX省西部。海拔1500余米,方圆约400平方公里。泰山不仅雄伟壮观,而且是一座历史文化名山,过去3000多年一直是人们前往朝拜的地方。据记载,共有72位帝王曾来此游览。许多作家到泰山获取灵感,写诗作文,艺术家也来此绘画。山上因此留下了许许多多的文物古迹。泰山如今已成为中国一处主要的旅游景点。LocatedinwesternShandongprovinceineasternChina,MountTaistandsover1500metersabovesealevelandcoversanareaofabout400squarekilometers.Itisamountainofhistoricalandculturalsignificance.ReligiousworshipofMountTaidatesback3,000years.Inrecordedhistory,72emperorscameheretopayhomagetoheavenandearth.MountTaihasseenmanypoets,literaryscholarsaswellaspainterswhohavetraveledthereforinspiration.ThatexplainswhyMountTaifeaturesnumerousculturalrelicsandhistoricsites.MountTaihasbecomeoneoftheleadingtouristattractionsinChina.四级翻译二：华山位于华阴市,距XX120公里。华山是秦岭的一部分。秦岭不仅分割陕南与陕北,也分隔华南与华北。与从前人们常去朝拜的泰山不同。华山过去很少有人光临。因为上山的道路极其危险。然而,希望长寿的人却经常上山,因为山上生长着许多药草,特别是一些稀有的药草。自上世纪90年代安装缆车以来,参观人数大大增加。MountHuaislocatedinHuayinCity<Shaanxi,China>,120kilometersawayfromXi’an.ItispartoftheQinlingorQinMountains,whichdividenotonlynorthernandsouthernShaanxi,butalsosouthandnorthChina.UnlikeMountTaithatusedtobefrequentedbyworshipers/pilgrims,
