Sam is a four year old boy. He lives in the USA with his father and mother. His father works in a hospital. He goes there by subway. He can read books on it. His mother is a worker in a factory. She often walks to work. They usually do some shopping on Sundays for the next week. But this Sunday they are going to the park to have a picnic because it is Sam's birthday.
Look, Sam has many birthday gifts(礼物). One of them is a nice drum. He likes music. Of course Sam likes the drum very much. He makes a noise with it all day. His parents don't mind. They are happy. But one of the neighbours(邻居)doesn't like the noise. One day, she brings a knife and says to Sam, “Sam, do you know, there's a very nice gift in your drum. Here's a knife. Open the drum and let's find it. ”“OK!”Sam answers.
