In almost every big city in the United States, football is a popular sport.
American football is not like soccer. Players sometimes kick the ball, but they also throw the ball and run with it. They try to take it to the other end of the field; they have four chances to move the ball ten yards. If they move it to the end of the field, they can receive six points. This is called a touch-down.
It's difficult to move the ball. Eleven men on the other team try to stop the man who has the ball. If the man does not move the ball ten yards, his team kicks the ball to the other team.
The football season usually begins in September and ends in November. Each team plays ten or eleven games each season. If a team is very good, it may play another game after the season ends. The best teams play again on January 1st. Thousands of people come to watch it when there is a football game. They all yell(欢呼)for their favorite team. They dance and jump while they are yelling.
Almost everyone in the United States likes football. Some of them enjoy playing it while others enjoy watching it. They all think it is a wonderful game.
