I want to tell you a story about myself at the airport. I wanted to fly to France with my family on vacation. Before we took the plane, we had to go through the metal detector (金属探测仪) at the airport. When I walked through it, the alarm rang.

“Come here, young man.” said the guard at the airport. “Take everything out of your pockets. ” So I took my wallet out and put it on the table. Then I walked through the metal detector again. This time, the alarm didn’t ring. My mother said that maybe there was something made of metal in my wallet, but I didn’t think so. Anyway, we got on the plane successfully and flew to France. The trip was great and I had a good time there.

When we went to the airport in France to fly home, I got into trouble again. When I went through the metal detector, the alarm rang again. I was surprised, so I asked the guard about it. “Let me see what’s in your wallet,” said the guard. So I took out everything out of my wallet. “This one is made of metal,” said the guard, pointing at the pen I bought last week.
