1. touchdown (TD), 6 points.

a touchdown is when a player runs into the opponent's end zone with the ball, or receives a pass in the opponent's end zone (provided that his feet must touch the ground when receiving the ball, and he has not dropped the ball or been tackled and pushed out of the end zone before landing). ?

The English word "touchdown" originally means "touching the ground", which comes from rugby (the ball must touch the ground when it is held in the scoring area to be effective), but there is no rule of "touching the ground" in American football, as long as the ball passes over the end area when it is held. ?

in NFL rules, as long as any part of the sphere, no matter how much, enters the end zone, a touchdown can be formed. In addition, any post at the four corners of the sphere's contact end area can also be regarded as a touchdown, provided that the ball holder is not tackled and fell to the ground before contact.

2. Shoot (field goal, abbreviated as FG) and score 3 points.

The method is to kick the ball over the goal crossbar and between the two goalposts. If the ball hits the goalposts and bounces back, it will be judged as a failed shot. When shooting, the ball must land first. Usually, the Holder is responsible for pressing the ball upright on the ground, and then the kicker kicks the ball out, which is called a placed kick.

Another unusual method is that the kicker throws the ball with a normal straight kick, but the kick is slightly delayed, and the ball is kicked out at the moment when it just touches the ground, which is called a drop kick.

usually, when the attacker is close to the scoring line, but it is difficult to advance enough yards before the end of the fourth attack, or the time is too tight to score in other ways, he will choose to shoot. If you fail to shoot in high school, you will lose possession of the ball to the defender, but you can still keep possession of the ball if you don't attack in the fourth gear in college.

3. safety (commonly known as "suicide ball"), 2 points.

when the attacking side is forced to retreat to its own end zone, and then it is tackled or dropped, the defending side scores 2 points. Some offenses by attackers in their own end zone will also be awarded security points by the defenders. ?

what are the kick-off rules of football?

the game starts with a kickoff. The defender's kicker puts the ball on the tee of his own 3-yard line and then kicks it to the attacker. After catching the ball, the attacker's backhand will try to push forward until it is intercepted by the defender. The attacker then starts an attack from where the ball is intercepted. ?

If the backhand catches the opponent's kick-off in his own end zone, he has two choices:

Either he rushes out of the end zone with the ball and goes to the opponent's site run array until he is intercepted; Either touch the ground with your knees after holding the ball, that is, stop the ball, then the ball will be placed at the 2-yard line of the attacker and the attacker will start the first round of attack.
