打羽毛球用英语：
Playing badminton is an enjoyable and healthy way to exercise. It can be played both indoors and outdoors, and is a great way to have fun with family, friends or even strangers. To play badminton, you will need four players, two rackets and a shuttlecock. The court is divided in half by a net and the players stand on each side of the net. The objective of the game is to hit the shuttlecock over the net and onto the opponent’s side of the court. The first team to score 21 points wins the game. A rally is started by one player serving the shuttlecock over the net. The opposing team must then hit it back over the net. The game is usually played in sets, with each team playing two out of three sets to win the match.
Badminton is a great way to improve your hand-eye coordination, agility and stamina, while having fun and socializing. It is also relatively inexpensive, with minimal equipment and court costs. All you need is a racket, shuttlecock and a court, and you’re ready to start playing!
