What is a youth? Impetuous fire

何为少年？熊熊燃烧的烈火，

What is a maid? Ice and desire

何为少女？冰霜与欲望的结合，

The world wags on

年华终将逝去。

A rose will bloom, it then will fade

玫瑰盛开，而后凋萎，

So does a youth, so does the fairest maid

少年也是，最甜美的少女亦复如此。

Comes a time when one's sweet smile

当那时，脸上是甜美的微笑，

Has its season for a while

那就是爱的季节，

Then love's in love with me

我心里充满了依恋。

Some may think only to marry

有人只想到结婚，

Others will tease and tarry

有的人却不屑且犹豫，

Mine is the very best parry

我的藉口最是高超：

Cupid he rules us all

丘比特早已将我们的心射去。

Caper the caper, sing me the song

尽管嬉戏去吧，并为我唱一首歌，

Death will come soon to hush us along

死神终将来临，令一切噤声，

Sweeter than honey and bitter as gall

甜如蜜糖，苦若胆汁，

Love is a past time and never will pall

爱虽磨人，却永不走味，

Sweeter than honey and bitter as gall

甜如蜜糖，苦若胆汁，

Cupid he rules us all

丘比特早已将我们的心射去。

A rose will bloom, it then will fade

玫瑰盛开，而后凋萎，

So does a youth, so does the fairest maid

少年如此，最甜美的少女亦复如此。
