阅读理解。One Friday night, a poor young man stood at a gate (大门) of the railway station(火车站). He played his violin and many people put money into the hat in front of him.
The next day, the young man came to the gate again, and put his hat on the ground. But different from what he always did in the past days, he took out a large piece of paper with some words in it and laid it on the ground. It said, "Last night, a gentleman put an important thing into my hat by mistake. Please come soon, Mr. Sang."
After about an hour, a middle-aged man ran to the young man in a hurry (匆忙) and said, "It's you! You do come here. I know that you're an honest (诚实的) man and will certainly come here," The young man asked, "Are you Mr. George Sang? Did you lose anything?" "A lottery (奖券) ticket," answered the middle-aged man. The young man took out a lottery ticket and gave it to the man.
The prize of the lottery ticket was $50,000. Yesterday when the middle-aged man learnt that he had won, he was very happy. He took out 50 dollars and put it in the hat. However, the lottery ticket was also thrown in.
Later, someone asked the young man, "You play the violin in the railway station every day to make money. Why didn't you just take the prize of the lottery ticket for yourself?" The young man said, "Although I don't have much money, I live happily. But if I lose honesty, I won't be happy forever (永远)."
