(B)
The Mid-Autumn Festival is coming. Joe's mother is making some ice cream mooncakes for the family. But there isn't much sugar and flour. So Joe and his father are going to buy some. They walk to the supermarket. On the way, they see a big black dog. The dog walks to them and begins to bark （吠）. Its teeth are sharp and white. Joe is afraid of the dog because it may bite him. He wants to run away. His father says, “Don't be afraid, Joe. Don't you know the proverb （谚语）'A barking dog does not bite, ?" "Oh, yes, " says Joe. "I know the proverb, you know the proverb, but does the dog know the proverb?" "You are right, " says his father. "We should be careful about the dog. It is never good to take an enemy （敌人）for a friend. But there is nothing to be afraid of. Just walk away. "
