惠普打印驱动m128fp:歌曲“《When you know》”怎么翻译？

《when you know》是大家耳熟能详的芝华士广告的配曲：

we could be together
everyday together
we could sit forever
as loving waves spill over

verse:
the moon is fully risen
and shines over the sea
as you glide in my vision
the time is standing still
don’t shy away too long
this is a boundless dream
come close to me my reason
i’ll take you in my wings

chorus:
we could be together
everyday forever
we belong together
further seas and over

verse:
in the garden of the sea
i see you looking over
with my wistful melody
you leap into the water
it is no breaths sighing
this is the mermaid song
the singing of my sisters
the sea has drown for long

曲调十分圆润优美。曲名含义深幽，以男女之爱暗寓对芝华士的眷恋，确实难以准确翻译。
试译作《但愿你明白》，不知可否。

楼上的错了，哪个歌词是Mermaid Song<美人鱼之歌>的，哪个才识正宗的芝华士广告歌来的。When You Know的歌词在下面
Shawn Colvin - When You Know

When you know
that you know
who you love,
you can't deny it.
Or go back,
or give up,
or pretend
that you don't buy it.
When it's clear this time you've found the one, you'll never let him go
Cos you know
and you know
that you know.
When you feel
in your skin
in your bones
and the hollow
Of your heart,
there's no way
you can wait
till tomorrow.
When there isn't any doubt about it once you come this close
Cos you know
and you know
that you know.

You can feel love's around you
like the sky 'round blue
This is how love has found you,
now you know what to do.

When you know
that you know
who you need,
you can't deny it.
Or go back,
or give up,
or pretend
that you don't buy it.
When it's clear this time you've found the one, you'll never let him go
Cos you know
and you know
that you know.

And it's time
you come in
from the cold.
Haaa...
And you know
that you know.

当你知道的时候，
如果是你何时知道的，应该是when did you know

当你了解（明白）的时候
嗯，一听就知道事情歌的名字！

你何时知道的

突然,你知道了!
