　　American Football

　　American football is a unique sport-it is a game about gaining territory as much as it is about scoring points. When two teams step onto a football field,each is battling for every inch it can take from the other. Each team wants to defend the field that is behind it and invade the field in front of it. Ultimately,they want to gain enough ground to score a touchdown or field goal.

　　Ground Rules

　　Football is a game of inches played on a field measured in yards-English measurements are used to track movements on the field.Teams succeed based on how many yards they accumulate or allow. An official NFL football field is a rectangle that is 120 yards long and 53 yards. I foot wide. Most fields are covered in grass and set in an outdoor sphere and has a lengthwise circumference and a width-wise circumference in the middle of the ball.

　　With the equipment identified and the field set, we can now play a game.An NFL game is divided into four quarters with an extended halftime break between quarters two and three. Each quarter is 15 minutes long. lf the teams are tied after four quarters of play,they play an additional overtime period of 15 minutes. In the overtime, the first team to score wins.

　　While the game time adds up to one hour, it usually takes three to four hours to play a game. Teams can stop the clock by running out of bounds,throwing an incomplete pass, or calling a time-out, of which they have three per half. Time also stops for each of the two-minute warnings, observed two minutes prior to the end of the second and fourth quarters.
