The world of sports is different so any person can choose his or her favorite sport. Adel, a young girl is crazy about basketball and as a professional, she tells her new friends about the benefits of this amazing sport activity. She wants more young people to play basketball.

Firstly, while playing the game, children have to run, jump, and spring on their feet, bend over, raise their hands, and throw the ball. Therefore, all muscle groups are trained and developed: legs, arms, and back.

Secondly, a child becomes more agile; he or she skillfully owns the body and confidently coordinates all movements. The lungs and heart are perfectly strengthened - they begin to "work like a clock."

To pass the ball, you need a good eye and logical thinking because you should guess where the ball will be, where your teammate or an opponent will locate in the next second. Basketball develops these important qualities very well. In addition to physical qualities, basketball teaches children to control and collaborate with each other.

Basketball is one of the most entertaining, challenging, and exciting sports in the world. You can learn the basic rules and the fundamental skills necessary to play. Here are the simple rules of the game.

You need a ball and a hoop.

Divide into two teams of 5 people each.

Score points by shooting the ball through the hoop. In basketball, an offensive player can score between one and three points with a shot, depending on where he/she is standing.

Move the ball by dribbling or passing to a teammate.

Professional players say basketball is not really hard to play. You just have to practice your dribbling, passing, moves, and shooting skills. Its takes dedication, but it is also a lot of fun.




1)When a player is dribbling, he/she has to____ over.

3)Players score points by shooting the ball through the____.​
