they are directly from America

Mrs.Smith lived in London. One day she received some American
　　dollars from her daughter who was working in New York. She went to
　　a jewelry shop for a pair of earrings. At the counter, the salesman checked
　　each note carefully to see if the money was real. It made the old woman
　　impatient. At last she couldn't wait anymore, uttering:
　　　　"Trust me, sir, and trust the American dollars. they are directly from
　　America."

直接从美国来的

史密斯太太住在伦敦。一天她收到在美国工作的大女儿寄来的钱。于是
　 她就去珠宝店想买一对耳环。在柜台，售货员非常仔细地检查着每一张美元。
　 这一来她有点儿不耐烦了。最后她忍不住了，说：“相信我，相信这些美元
　 吧。这可都是直接从美国来的呢。”
