Atlanta was a Greek princess. She was very beautiful and could run faster than    31           man in Greece. But she was not allowed to run in the Olympic Games. She was    32           angry that she said to her father she would not marry anyone who could not run faster than her. Her father said she must marry and asked her   33          she wanted to marry a king or prince. But Atlanta replied, “I will only be married to a man who can run faster than me. When a man says he wants to marry me, I will run  34           him. If he cannot run as fast as me, he         35          (kill). No one will be pardoned.”

Many kings and princes wanted to marry Atlanta but when they heard of her rules, some of them    36        (sad) went home. Other men stayed to run the race. There was a man called Hippomenes who was amazed when he heard of Atlanta’s rules. “Why are these men so   37         (fool)? Why will they let    38        be killed because they cannot run as fast as this princess?” Then when he saw Atlanta come out of her house   39         (run), Hippomenes changed his mind. “I         40           marry Atlanta — or die!” he said.
