Reading Test The Magic Basket
A mother and her little son live in a little house. They are very poor. All they have is a grey goat. One day the mother says, “We have got no money, we have got no bread. You should go and sell the goat”. The boy takes the goat and goes to the town. He meets a farmer with a large basket in his hands. “Sell me your goat”, says the farmer.“What can you give me for it?” asks the boy.“I can give you this basket”, says the farmer.“What good is this basket for me?” says the boy. “What can I put in it? I’ve got no bread, I’ve got no eggs and I’ve got no apples!”“My little girl is ill”, says the farmer. “She must drink some milk from a grey goat every day or she will die”. The boy is kind.
