1 . If you like dangerous and exciting sports, maybe skydiving (跳伞) is for you. First skydivers jump from an airplane.     1     Sometimes, skydivers do gymnastics in the air—for example, they might hold their knees close to their bodies and turn upside down. Finally, skydivers pull a cord (绳索) and a parachute (降落伞) opens.     2     Skydivers usually wear hard helmets to protect their heads. Sometimes, skydivers are on a team in a competition such as the Olympics. The team works together and does movements in the air.     3     The team with the most points wins.

It’s difficult to see what skydivers do when you’re standing on the ground. Often, people fly in airplanes to make a tape of the skydivers.     4    

If skydiving doesn’t sound fun to you, there are plenty of other sports.     5     Surfers stand out in the middle of the ocean on a long, flat board. Surfers don’t have to worry about jumping out airplanes, of course---but don’t forget about the shark!
