    In almost every big university in the United States, football is a favorite sport. American football is not

like soccer.

    Players sometimes kick(踢) the ball, but they also throw(扔) 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(码). They can carry it or

throw it. If they move it to the end of the field, they receive six points. This is called a touch-down(持球触地).It's difficult to move the ball. Eleven men on the 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.

they yell. Each team plays ten or eleven games each season. The season begins in September and ends

in November. If a team is very good, it may play another game after the season ends. The best teams

play again on January the first. Many people go to see these games and many others watch them on TV.
