Today is a fine day. It's the little pig Bob's birthday. Look! Mother Pig is making a birthday cake and some delicious food. Father Pig is cleaning the living room. The little pig is waiting for (等待) his friends at the door.

    Bob's good friends—the monkey, the rabbit, the elephant and the bird come to his home. He is very happy because his friends get nice presents for him. The monkey has some apples for him. The rabbit has some flowers. The elephant has a big basket of grass on her nose for Bob. The bird sings the birthday song for Bob. They enjoy the delicious birthday cake and food. They feel very happy.
