Nothing gold can stay nature's first green is gold是谁的诗啊?

罗伯特.弗罗斯特——美景易逝 Nothing gold can stay 岁月留金 Nature's first green is gold,大自然的第一抹新绿是金,Her hardest hue to hold.也是她最无力保留的颜色..Her early leaf's a flower; 她初发的叶子如同一朵花,； But only so an hour.然而只能持续若此一刹那.Then leaf subsides leaf,随之如花新叶沦落为旧叶.So Eden sank to grief.由是伊甸园陷入忧伤悲切,So dawn gose down to day,破晓黎明延续至晃晃白昼.Nothing gold can stay.宝贵如金之物岁月难保留.
