语言素材：
The original Olympic Games were part of an important religious festival to honor the Greek gods, especially Zeus. They were held in a valley in Olympia every four years and men from all the Greek city states attended. Women did not compete in the games or even attend. The first record of the Olympic Games dates from 778 BC, but they were probably established hundreds of years before that.
At first there was only one competition in the games--a 200m foot race. The distance was based on a myth about the hero Hercules who was said to have run this distance in one breath. At later Olympics other events were introduced, including a 365 meter and a 5 kilometer race, boxing and wreathing, chariot races and the pentathlon jumping, running, javelin, discus and wrestling.
Athletes came to Olympia to train full-time for 10 months. Before they were allowed to compete, they were examined by a committee of 10 men to make sure they were of good character and physically fit. All wars between cities had to stop for the five days of the games.
The prize for the winners was a crown made from an olive tree branch, but with a gold handled knife from a seared tree. The olive branch was believed to give the athlete great strength and health. The winner gave public thanks to Zeus and to his city or district. Winners were believed to have gained the favor of the gods.
