Once there was a true love in front of me,I did not cherish,until after the loss of just Too Late To Regret,the most painful thing in the world,if God give me another chance,I would say to the girl,I love you,if not to fall in love in this add a deadline so,I hope it is ten thousand years.
上面的那段英语可能有用词和语法上的错误。
曾经有一份真挚的爱情摆在我面前，我没有好好去珍惜，直到失去以后才后悔莫及，人世间最痛苦的事莫过于此，如果上天再给我一次重来的机会，我会对那个女孩子说，我爱你，如果非要在这份爱上加个期限的话，我希望是一万年。

答案

Once there was a true love in front of me, but I did not cherish it.I didn't regret until i finally found i have lost it（这个时态没有错,失去已成一个一般的状态,延续到现在,所以用现在完成时）,but it was too late. Nothing could be more painful（miserable）than this!If God could be kind enough to give me another chance, I would say to the girl that“ I love you” .If i have to（have no choice but to 觉得更好）set a deadline for my love,then, I hope it is ten thousand years.
