Some children are flying kites near the river. They are very high and Peter can see them from the classroom. After lunch his aunt comes to see his mother and brings a kite to him. It looks like a bird. He wants to fly it but his mother doesn’t let him do that.

“It’s time to go to school,” says his mother, “You can fly it after dinner.”

The boy is unhappy, and says goodbye to his aunt and leaves. Now he is in the classroom but he doesn’t listen to Miss Black. He only thinks how to fly the kite. Miss Black writes something on the blackboard and then turns to the class.

“Name nine things with milk in them, Peter.” she says.

The boy doesn’t hear her and still sits there. A boy in Row 4 beats(敲打)his back and he knows it. He stands up and Miss Black asks him the question again. He thinks for some time and then says, “Yes, madam, tea, coffee, cake and …er…six cows(奶牛).”
