At auction spot， someone has lost a bag， in which has the vital document.

The owner says， "Once who picked it up brings it to me， I will take out 200 dollars to remunerate reward him or her."

On hearing the news， another chap（小伙子，家伙） shouts out:" I reward 300 dollars."

拍卖会上，有人的包丢了，里面装有重要文件。物主说：“有谁拣到送还，我将拿出200美元以表酬谢。”
