It was Jimmy's birthday, and he was five years old. He got a lot of nice birthday gifts(礼物) from his family, and one of them was a beautiful drum. "Who gave him that thing?" Jimmy's father said when he saw it. "His grandfather did." answered Jimmy's mother. Jimmy liked his drum very much. He made a terrible noise with it, but his father didn't mind. He was working during the day and Jimmy was already in bed when he got home in the evening, so he couldn't hear the noise. But one of their neighbors didn't like the noise at all. So a few days later, she took a sharp(锋利) knife and went to Jimmy's house while he was hitting his drum. She said to him, "Hello, Jimmy, there is something very nice inside your drum. Here is a knife. Open the drum and let's find it."
