     In almost every big university (大学) in the United States, football is a favourite sport. American

football is different. 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(机会)to move the ball ten yards(码). They

can carry it or they can throw it. If they move the ball ten yards, they can try to move it another ten yards.

If they move it to the end of the field, they receive six points.

     It is difficult to move the ball. Eleven men on the other team try to stop the man with the ball. If he

does not move the ball ten yards, his team kicks the ball the other team.

     Each university wants its own team to win. Many thousands of people come to watch. They all shout

for their favourite team.

     Young men and women come on the field to help the people shout more. They dance and jump while

they shout.

     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 1, the first day of the New Year.

Many people go to see these games and many others watch them on TV.
