The Golden Duck


A.Не always helped poor people because he knew the meaning of happiness.

money left.

  D. The princess
made a magic spell and gave him a hundred gold coins.


E. He bought a lot of expensive things and

F. There he

G. Hard work and good health bring happiness, not

H. The shoemaker felt sorry for him and gave him some money.



Once upon a time there was an unhappy
shoemaker. He wanted to be rich because he thought
this was the only way to be happy. (1) The old man told him what to do.
"Go to the castle and look for the golden duck. It's really a
princess, and she will tell you what to do."

The shoemaker
was excited and went to the castle. (2) When he saw the duck, she turned into a
beautiful princess. "I want to be rich
and happy," he said. (3) "Spend all this money tomorrow," the
princess said, "but only on yourself, not on other people. Then when you have nothing I will make you
rich." "This is easy,"
thought the shoemaker, and the next day he started spending the money. (4) Then
he met an old soldier, a beggar, with
one leg. "I'm hungry, help me," he said. (5) The magic spell stopped working, and the princess appeared.
"You gave some money to another person," she said. "I cannot
make you rich." Then the old soldier said to the shoemaker, "Don't be
unhappy. (6)" At last the
shoemaker understood. He .worked hard, saved money and started his own shop. In time he got married and had a family.
(7) And he lived happily ever after.
