Many people would like to watch sport matches. First, you need to know about audience manners.

Most sporting arenas(竞技场) have rules for audience written on the back of the tickets. Read your ticket carefully before you arrive. Try to reach 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 bottle and other rubbish.

During exciting games, try to control yourself. Don’t criticize(批评)the performance of players and coaches. Be careful with your words, since some may cause anger among other people in the audience

Applause(鼓掌)is a special form of body language you can use to communicate with players, but you should do it properly. When players first appear, clap your hands together to welcome them, but don’t go on for too long. After an excellent performance, applaud warmly. If someone fails, your applause will help encourage them.

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

Enjoy artistic gymnastics silently. 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 shooting centers.

To be good audience, you should spend time learning the specific(明确的) rules and the culture of each event.
