     Most people can think of a sport they would love to see in the Olympics. But they often don't realize

how hard it is to add a sport to the Olympics. A sport needs to be well-organized and popular before the

Interracial Olympic Committee (IOC) will consider it. An international federation must govern (控制) the

sport by making rules and making sure athletes meet Olympic standards (标准). What's more, men from

at least 75 countries and women from at least 40 must play the sport.

     However, even meeting those conditions isn't enough. The IOC always tries to keep the member of

athletes at about 10,000 for each Olympics.Since most modern Olympics already include so many athletes,

introducing a new sport often means cutting other events.

     The country that hosts the games is allowed to suggest what new sports should be included. While new

sports are added to the Olympics,most of them will simply become events in another sports meeting. In

Beijing, open water swimming will become part of swimming, while women's steeplechase (障碍赛) will

be added to athletics.
