It's Jim's birthday today. He is five years old. He gets many nice birthday presents(礼物) from his family and one of them is a big drum (鼓). “Who gives him the drum?” his father asks. “His grandfather does,” answers Jim's mother. Jim likes his drum very much. He makes a noise(噪音) with it, but his mother doesn't say anything about it. His father is not at home. He is working in a school. So he doesn't hear the noise. But one of the neighbours (邻居) doesn't like the noise at all. So one morning she takes a knife and goes into Jim's room. Jim is making a noise with the drum. She says to him, “Hello, Jim. Do you know there is something nice in your drum? Here's a knife. Open the drum and let's find it.”
