　　The Winter Olympics has been hosted on three continents by eleven different countries. The

Games have been held in the United States four times in France three times; and in Austria, Canada, Japan, Italy, Norway, and Switzerland twice. Also, the Games have been held in Germany, Yugoslavia and Russia once. The IOC has selected Pyeongchang, South Korea, to host the 2018 Winter Olympics and Beijing, China, to host the 2022 Winter Olympics. No city in the southern hemisphere(半球) has hosted or even been an applicant to host the Winter Olympics; the major challenge preventing one hosting the games is the dependence on winter weather, and the traditional February timing of the games falls in the middle of the southern hemisphere summer.

　　Twelve countries -Austria, Canada, Finland, France, Great Britain, Hungary, Italy, Norway, Poland, Sweden, Switzerland and the United States - have sent athletes to every Winter Olympic Games. Six of those - Austria, Canada, Finland, Norway, Sweden and the United States - have earned medals at every Winter Olympic Games, and only one - the United States - has earned gold at each Games. Norway leads in terms of number of gold medals and overall number of medals. Germany and Japan have been banned at times from competing in the Games.

　　The Winter Games have had only one team boycott when Taiwan decided not to participate in the 1980 Winter Olympics held in Lake Placid. Prior to the Games the IOC agreed to allow China to compete in the Olympics for the first time since 1952. Taiwan returned to Olympic competition at the 1984 Winter Games in Sarajevo(徽章) as Chinese Taipei. The agreement remains in place to this day.

32. Why hasn't the Winter Olympics ever been hosted in the southern hemisphere?
