Nowadays,kids all over the world are doing more and more extreme （极限的） sports.The most popular ones include inline skating （轮滑）,BMX cycling （自行车越野）,snowboarding,skateboarding and bungee jumping （蹦极跳）.Why are they so extreme?They all have a few things in common:they\’re fast,dangerous and usually send people flying through the air.
These sports started in the streets,but they were made popular by ESPN,the American TV sports network.ESPN held its first international extreme sports competition,called the "X Games," in 1995.The X Games soon became a twice-yearly event with winter and summer games.
Now,some Chinese kids are falling in love with these cool sports.In cities like Beijing and Guangzhou,in the parks or streets,kids often practice inline skating or skateboarding,learning new tricks （花样） from their friends.Extreme sports are becoming so popular,even the Olympic Games are starting to welcome them.Mountain biking is now a part of the summer Games,and snowboarding is in the winter Games.
BMX cycling was added to the Beijing Games in 2008. "It\’s a change that we can\’t stop," said Mark Ryerson,a US Olympic historian. "The Olympics have to look into sports that people are interested in."
