Tennis is an action-filled game played with rackets and a ball by two players or four players. It’s played outdoors or indoors, on a flat surface called a tennis court. The surface can be hard, like concrete or asphalt. It can also be made of clay or even of grass!
The court is a large rectangle. It’s divided in half by a net 3 feet (0.9 meters) high. White lines mark the outline of the court. Each player tries to hit the ball with the racket so that it goes over the net and bounces inside the lines on the other side.
Tennis is a popular sport to play and to watch. The best players in the world compete in tournaments in different cities. There are four major tournaments called grand slam events. They are the United States Open, the French Open, the Australian Open, and Wimbledon. Wimbledon is played at a tennis club in Wimbledon, England, near London.
