英语翻译
When my son,Mark,was in the third grade,he saved all his pocket money for over three months to buy holiday presents for those he loved.The third Saturday in December Mark said that he had made his list and had twenty dollars in his pocket.
I drove him to a nearby supermarket.Mark picked up a hand basket and went off on his own while I waited patiently reading a book in the car.It took Mark over 45 minutes to choose his presents.The clerk rang in his purchases(把他所购物品输入现金出入记录器) as I politely looked the other way.Mark kept within his budget(预算)and reached into his pocket for his money.It was not there!There was a hole in his pocket,but no money.Mark stood in the middle of the store holding his basket,tears（眼泪） rolling down his cheeks.His whole body was shaking with his sobs.Then an amazing thing happened.A customer in the store came up to Mark.She knelt down and took him in her arms.
"You would do me the greatest favour if you let me replace(补还)your money," said the woman."It would be the most wonderful present you could ever give me.I only ask that one day you pass it on.One day,when you are grown-up,I would like you to find someone you can help.When you help this other person,I know you will feel as good about it as I do now."
Mark took the money,dried his tears and ran to the checkout counter as fast as he could.I think we all enjoyed our gifts that year almost as much as Mark enjoyed giving them to us.
I would like to say "thank you" to that very kind woman.I would like to tell her that four years later Mark went house to house collecting blankets and clothes for the homeless people in the Oakland fire－and he thought of her.And I want to promise her that Mark will never forget to keep passing it on

我儿子马克在读三年级时曾经储蓄了三个月的零用钱,为的就是要给心爱的家人和朋友购买礼物.十二月的第三个星期六,马克告诉我他已经把礼物清单给写好了,而他口袋里总共有二十块钱.
我把他送到了附近的超市.马克自己提了个购物篮子去选礼物,我则坐在车里耐心地读着一本书等他出来.马克用了45分钟来选他所要买的礼物.收银员（把他所购物品输入现金出入记录器) .我则礼貌性地往别处看.马克所选购的礼物并没有超出他的(预算).他把手伸进口袋里想把钱拿出来,但是他发现钱不见了! 原来他的口袋破了个洞.马克手提着购物篮子站在超市里, （眼泪）开始往下流.他哭得连身子都在颤抖.然后一件不可思议的事发生了.一位女顾客走到马克的面前.她蹲了下去,并且把他拥入怀里.
"让我行一行善吧,让我帮你把你的钱给（补还）了, 好吗?"那位女顾客说道. "那将会是你送给我最好的一份礼物.我只求有一日你可以将这个善念传给别人.有一天,当你长大了,我希望你可以去帮助他人.当你这么做的时候,我知道你也会和我现在一样开心的." 马克接过了钱,擦干眼泪,然后跑回收银台付了钱. 那年,收到礼物的我们和送礼物的马克都一样的快乐.
我想和那位女顾客说一声“谢谢”.我想告诉她四年后,马克到处去收集被子和衣服,为的就是要将它们送给在北加州屋仑大火中失去家园的人们.他是因为想着她才去做这件事的. 我也想给她一个承诺,那就是马克永远不会忘记将这份善念继续的传下去的.
