As we know, the ancient Olympic Games took place in Olympia in Greece every four years between 776BC and 339BC. Only men and boys could compete in the ancient Olympic Games. Married women were not even allowed to watch the Games; only young girls, boys and men could watch.
However, in modern times, there are two main sets of Games—the Summer and Winter Olympics, and both are held every four years. Athletes from any country who have reached the agreed standard for their event will be admitted as competitors. Therefore, there are many significant differences between the modern and ancient Olympics, although certain similarities exist.
In this text, Pausanias, an ancient Greek writer, has come on a magical journey to find out more about the ancient and modern Olympics. Has he got what he wants to know? I think you have got the answer. OK. First, let’s do a survey about Olympics.

They may come fromanywhere in the world.
P: Winter Games? How can the runners enjoy competing in winter? And what abouthorses?
L: Oh no! There are no running races or horseriding events. Instead there are competitionslike skiing and ice skating which need snow and ice. That’s why they’re calledthe Winter Olympics. It’s in the Summer Olympics that you have the runningraces, together with swimming, sailing and all the team sports.
