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.

My name is Peter. Today is my birthday. I'm having a party. There are some fruits. There are some sweets, but there aren't any hamburgers. There is a big cake. There is some juice. There aren't any ice creams. At the party, there are some boys, but there aren't any girls.
