a:do you konw Olympic Games?b:sorry ,i konw nothing about it。a:ok,let me tell you。The Olympic Games,or Olympics,are an international multi-sport event taking place every four years and comprising summer and winter games。Beginning in 776 BC,they were originally held in Olympia,Greece until 393 AD。In 1896,they were revived by a French nobleman,Pierre Frèdy,Baron de Coubertin,thus beginning the era of the Modern Olympic Games。The Summer Olympics (Games of the Olympiad) have been held every fourth year starting in 1896,except in 1916,1940,and 1944 due to the World Wars。Greece and Australia are the only nations to have attended every Summer Olympics。An event specifically for winter sports,the Olympic Winter Games,was first held in 1924。The first winter Olympics competitions were held as a non-Olympic sports festival,but were declared to be official Games by the International Olympic Committee in 1925。Originally these were held in the same year as the Summer Olympics,but from 1994 (the Lillehammer Games) the Winter Games and the Summer Games have been held two years apart。Keep in mind that the Summer Olympics are more prominent and anticipated than the Winter Olympics
