In 776 B.C.£¬the Olympic Games got its name because it was in Olympia£¬Greece that the Games were held. The Olympic Games are held every four years. There are two main sets of Games---the Winter and the Summer Olympics£¬and both are held every four years on a regular basis. The Winter Olympics are usually held two years before the Summer Games. Nowadays, there are more sport events than before.
