My name is Ken. Three years ago, I saw a beautiful stamp on an envelope. The letter was from my father’s friend. My father let me keep it and that was the first stamp I had. Now I have about two hundred stamps. I always go to the post office to buy stamps on the weekend. Sometimes I use my pocket money to buy stamps, but I can’t buy the expensive ones. I have three pounds and it is just enough to buy a new stamp with a panda on it. So I am going to go to the post office near my house. stamp[st?mp]：郵票，蓋章 envelope['env?l??p; '?n-]：信封 hundred['h?ndr?d]：百 pocket['pɑk?t]：口袋 expensive[?k'sp?ns?v]：貴的 pound [pa?nd]：磅（重量，金錢）
