羽毛球英语怎么写的：

Badminton is a sport in which two or more players use a racket to hit a shuttlecock back and forth over a net. It is usually played with two or four players at a time, either indoors or outdoors. The shuttlecock is made of a cork base covered with feathers, and is designed to be light and aerodynamic.

The objective of the game is to hit the shuttlecock over the net and into the opponent's court. Points are scored when the shuttlecock is hit out of bounds or when the opponent fails to return the shuttlecock. The first player or team to reach 21 points wins the game.

Badminton is a popular sport in many countries, including China, India, England, and the United States. It requires a lot of agility, speed, and precision, and is a great way to stay active and have fun.
