A Thank-you Note

　　Once I received a thank-you note from a friend whom I had helped. In the envelope were five lottery tickets that had been scratched, revealing the numbers. "Thank you very much for your help," the note read. "As a gift, I bought you some lottery tickets- sorry you didn't win. "

　　有一次，我收到一封感謝信，是一個我曾幫助過的.朋友寄來的。信封內(nèi)有五張彩票，都被刮過了，露出了數(shù)字。“非常感謝您的幫助，”信上寫道，“作為禮物，我給您買了些彩票----真遺憾，您沒中獎。”
