     In almost every big university in the United States, football is a favorite sport. American football is

  different. Players sometimes kick (踢) the ball that is oval (not round), but they also throw the ball with

 their hands 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 (长度单位,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 (点,分). 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 to the other team.

     Each university wants its own team to win. Many, many people come to watch. They all shout for their

 favorite 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 January1, the first day of the New Year. Many people go to see these games and many others watch them on TV.
