Jim likes cars. He has some model cars. He plays with them every day. He often goes out in his father's car. "I wish I could drive a car," Jim says. "No. You are too small. You must wait a long time before you can learn," his father says.
On his birthday, his father gives him a pedal car (脚踏汽车) as a present. Jim likes it very much and drives it every day. "I wish I could have a passenger (乘客) to ride the pedal car with me," Jim says. "But the car is too small," his father says, "It can only take you." But Jim doesn't think so. He goes out and finds a passenger! Who is the passenger? It's a dog.
