求翻译成英语：既不回头，何必不忘；若是无缘，何须誓言；今日种种，似水无痕；明夕何夕，君已陌路。

可以解释成为， 既然已经离开了,不能回到过去了,又何必去记得那些过去而念念不忘呢.
你我之间没有缘分牵引,何必需要誓言。
我们之间发生的种种事情,就像水划过一样的没有痕迹。
明天还是以后,你和我已经是陌路人.
所以可以翻译成，
Now that you have left and we can't go back,Why do you remember those memories in the past and it has been always kept in mind.
Between you and me, there is no fate traction,why the pledge was needed.
Everything that has happened between us,Like water across without trace.
No matter tomorrow or later,we have been strangers.

since no longer turn around the head, why must keep it in mind
as it is not destined, the promise is in vain
all the things today died away like the running water
what day is it tomorrow,however you have been a stranger
