the world is a rose:smell it and pass it to your friend 属于什么修辞?为什么

Metaphor：(暗喻）It is like a simile,also makes a comparison between two unlike elements,but unlike a simile,this comparison is implied rather than stated.For example,the world is a stage.世界是一个舞台
the world is a rose:smell it and pass it to your friend 世界就好比一朵玫瑰：闻过它,就把它送给你的朋友.（意在指感受过,并同朋友分享这个世界（玫瑰））
