I had a very unusual experience(经历)on Sunday. At ten in the morning, I was walking down the street when a UFO landed right in front of me. You can imagine(想象) how strange it was! An alien got out and walked down Center Street. I followed it to see where it was going, and I was very surprised when it went into a souvenir shop. While it was looking at the souvenirs(纪念品), the shop assistant called the police . Before the police arrived, the alien left the shop and then visited the Museum of Flight. while the alien was in the museum, I called the TV station. Isn’t that amazing!
