Jack and the beanstalk
This is the story of a little boy. His name is Jack. Jack lives with his mother. They are poor. They have got a goat, but the goat doesn’t make any milk. Jack takes the goat to the market. A good man sees Jack and the goat. He gives Jack some beans. "These are magic beans," says the good man. Now Jack is happy.
Jack goes home. "Have you got any money?" asks his mother. "No, but look! I’ve got these magic beans!" says Jack. "Magic beans!" shouts Jack’s mother. "You are a silly boy, Jack!" She throws the magic beans into the garden.
In the morning, Jack goes into the garden. He wants to find the magic beans. But there aren’t any magic beans in the garden! Now there is a very big beanstalk. Jack climbs up the beanstalk.
Now Jack is at the top of the beanstalk. He is on a cloud. There is an old woman on another cloud. "I remember your father," says the old woman. "A bad giant has got your father’s gold coins! He lives in that castle," says the old woman. Jack goes into the castle.
Jack watches the giant. The giant has got a sack. There are gold coins in the sack. They belong to Jack’s father! The giant counts the gold coins. He puts the gold coins in the sack. He hides the sack in the chest. Jack takes the sack and runs very fast. Jack runs out of the castle.
Jack runs to the beanstalk. He climbs down and down. The giant is behind Jack! He climbs down the beanstalk. Jack is in his garden. He cuts down the beanstalk with an axe. The beanstalk falls down. The giant falls down.
Now Jack and his mother aren’t poor because they have got lots of gold coins. They aren’t hungry because they have got lots of food. Jack and his mother are very happy.
