星爷的大话西游的那句经典台词用英语怎么说
曾经有一份真诚的爱情放在我面前,我没有珍惜,等我失去的时候我才后悔莫及,人世间最痛苦的事莫过于此.你的剑在我的咽喉上割下去吧!不用再犹豫了!如果上天能够给我一个再来一次的机会,我会对那个女孩子说三个字：我爱你.如果非要在这份爱上加上一个期限,我希望是……一万年
就这些.谢谢

I have had my best love before,but I didn’t treasure her.When I lost her,I felt regretful.It is the most painful matter in this world.If God can give me another chance,I will say 3 words to her --- I love you.If you have to give a time limit to this love,I hope it is 10 thousand years.
