　　运动项目怎样才能进入奥运会？

　　奥运会补充一个运动项目是一个漫长的过程。一个运动项目在纳入国际奥委会IOC的考虑范围之前需要满足很多方面的要求。首先，该运动项目必须有自己的国际联合会。其次，必须有至少4个大洲不少于75个国家的男子从事该项运动，或3个大洲不少于40个国家的女子从事该项运动。还不止这些。要增补一个新的运动项目，就必须淘汰一个当前的运动项目。这有助于国际奥委会对奥运会的预算进行控制。

　　哪些运动项目被淘汰了？,有些在过去是奥运会比赛内容的运动项目已经被淘汰了。这些被淘汰的项目既包括棒球等一些大家所熟悉的项目，又有像汽艇等一些不那么常见的项目。这些运动项目被认为不及以前流行了，必须让位于新的、更为流行的运动项目。

　　Which ones are in?

　　Some sports have been added, such as tae kwon do⑬， which was first included in the Olympics in 2000. The IOC is planning to change some of the sports in the next few years. In 2016, rugby⑭ and golf⑮， which were earlier played at the Olympics and then dropped⑯， will be included again, as they are now very popular and are played all around the world⑰.

　　Which ones are still trying?

　　Wushu is still applying to get into the Olympics. The IOC has still not approved⑱ the sport due to⑲ the concern about the balance of sports - there are already many other sports in the Olympics that are connected with fighting⑳， such as tae kwon do and boxing. However, the IOC is considering changing the number and type of Olympic sports in the future, so wushu fans may finally get what they are hoping for\s\up1(21(21).
