The behavior of courtside audiences is considered to be an important part of sporting culture. In 2004，after world champion Stephen Hendry lost to Ding Junhui in the China Open Snooker Championships，he complained of the noise from Chinese spectators（观众）. Perhaps you and your classmates could discuss how to behave while in the audience at the Olympic Games.

Most sporting arenas have rules for spectators written on the back of the tickets. Read your ticket carefully before you arrive. Try to teach your seat half an hour before the start of the event and don’t leave when a game is in progress. When you leave，remember to take away your soft drink bottles and other trash（垃圾）. It is really very impolite of you to leave any rubbish behind. Pay close attention to it.

During exciting games，try to control yourself. Don’t criticize the performance of players. But you should do it properly. When players first appear，clap your hands together to welcome them. Perhaps they will soon cheer up.

Applause is not welcome，however，while a game is in progress and players need to keep their concentration. Various sports have various rules for the audience.

Enjoying artistic gymnastics requires silence. But lots of cheering can really help basketball and football players. Snooker and table tennis courtside behavior includes a ban on flash photography. Mobile phones are not allowed in shopping centers.

To be a good spectator，you should take time to learn the game-specific rules and related culture of each event. If you know these rules，you are sure to have a good time when are enjoying a wonderful match.
