A man sat at an underground station in Washington, D.C., and started to play the violin. It was a cold day in January. He played six Bach（巴赫）pieces for about 45 minutes. It was rush hour and thousands of people went through the station, most of them on their way to work.

    Three minutes went by and the first person, a middle-aged man, noticed there was a musician playing. He slowed down and stopped for a few seconds and then hurried up to meet his schedule.

    After a minute, the violinist received his first dollar tip: a young woman threw the money in the box and continued to walk. Then another few minutes went by and someone stood against the wall to listen to him, but the young man looked at his watch and started to walk again. Clearly he was late for work.

    During the musician's performance, only six people stopped and stayed for a while, twenty gave him money but continued to walk. When he finished playing, no one applauded（鼓掌）. No one knew the violinist was Joshua Bell, one of the best musicians in the world.

    This is a real story. Joshua Bell playing in the underground station was organized by The Washington Post（《华盛顿邮报》）as part of a social experiment. One of the conclusions from this experiment could be: If we do not have a moment to stop and listen to one of the best musicians in the world playing the best music, how many other things are we missing?

    I am 13. It's my first time to go to New York. I go there with my friend Emma. We get to New York at about 10pm, and we want to do some sightseeing(观光). So we go to the Empire State Building. But the 86^th floor(层) is cold. A long time later, we go to the hotel(酒店).

    On the second day, we go shopping in the morning, visit the Statue of Liberty at noon, and go shopping again in the afternoon.

    It is rainy on the third day, but we get up early in the morning. We have some bread and go to Rockefeller Center. We see the whole city there. I feel like I am on top(顶部) of the world. In the evening, we walk around Times Square, watch all the people and the street performers(街头艺人). At 11pm, Emma and I go back to the hotel. We go back home the next day. New York is really a good place.

    Victor's hobby was collecting stamps. He had stamps from many countries, like England, Canada and China. On his birthday, can you guess what people gave him? That's right-stamps.

    Victor's favourite stamps came from France. He had almost every stamp from 1954 to 2004. He only needed one. That was a 1974 special edition. It was very hard to find.

    He looked for it everywhere. He asked his friends and relatives to help him. But nobody could find the stamp. It made Victor very sad.

    "Don't worry. Never give up," his father said to him. If you have enough patience, you'll find it one day.

    "I hope so," Victor said

    Victor also liked writing. He had a penfriend in France. They wrote to each other every month. Victor's penfriend, Phillip, usually used new stamps to send letters. Sometimes, his mother gave him stamps to use. Once Phillip's mother gave him a big, green stamp. It looked old. When Victor received the letter, he was very surprised. On the envelope, he looked carefully at the stamp. It was the 1974 special edition stamp. Victor was so happy. He told his sister, his mother and his father. "You see," his father said. "You did find your stamp. So it's good to have two things in life."

    "What are they?" Victor asked.

    "Friends and patience," he answered.
