Who told me the rules of playing football?

The standard international stadium is100 ~120m long and 64 ~ 75m wide. The standard of the stadium used in the World Cup finals is: length 105m, width 65m and turf. Official international competitions must be held on natural turf courses, not artificial grass balls. There are: goal line, sideline, center line, restricted area, goal, corner area, midpoint, middle circle and free throw arc on the football field. A corner flag with a height not exceeding 1.5m should be erected in every corner of the stadium. The width of the soccer goal is 7.32m and the height is 2.44m (Figure 10-36). )

The perimeter of the standard ball in international competition is 68~7 1cm, the weight at the beginning of the competition is 396~453g, and the inflation pressure is 0.6~ 1. 1 atmospheric pressure. The color of the ball should be obviously different from that of the stadium. It is usually white. You must use black and white balls to play a lighted game at night. No ball can be changed without the permission of the referee.

(2) Number of participants and competition time

In a regular football match, the number of each team is 1 1, among which there must be a goalkeeper, and three players can be changed in each game. When any team has less than seven players, the game cannot be played. Every regular football match has a referee, two assistant referees and a substitute referee. After the referee blows the whistle, the kickoff player kicks the ball forward until it rolls around, and then the game begins. The game time is divided into the first half and the second half, each half is 45min minutes, and the intermission time is not15 minutes. After the game is tied within 90 minutes, overtime is needed, which lasts for 30 minutes, up and down.

The two halves are 15min each, and there is no rest in the middle, only 10-36.

Change the venue and play sudden death. If overtime is still a draw, the winner must be decided, then the winner will be decided by penalty kick. 3 points for winning a game, 1 point for drawing a game, and 0 point for losing a game.

(3) The functions and powers of referees and assistant referees

In a football match, the referee can punish, warn or send off the players and coaches of both sides of the game according to the power given by the football rules until they are disqualified. The assistant referee assists the referee in enforcing the rules. When the whole ball crosses the sideline or end line, it should be marked which side kicks the goal, throws the foul ball or kicks the corner kick. When the whole ball crosses the goal line, the assistant referee raises the flag and points to the middle circle, and the referee whistles to win the goal.

(4) Offside and personal foul punishment.

Offside fouls and personal fouls are the most common in modern football matches. The penalty for offside foul should be based on the following three conditions.

1. At the moment when the attacker passes the ball, the players on the same team are closer to the opposing end line than the ball.

2. There are less than two defenders between the catcher and the opposing end line.

3. Enterprises that gain benefits from offside position or interfere with the game will also be punished by offside foul.

The punishment of personal fouls should be based on the spirit of football rules, identifying and distinguishing intentional fouls from reasonable actions, brave and tenacious actions, good style and misconduct.

Personal fouls mainly include: pulling people, mixing people, blocking and dangerous actions.

The most common foul in the game is that the purpose of fighting for the ball in the team is not the ball, deliberately pulling or kicking the opposing team member or deliberately shoveling the opposing team member in the tackle; A direct free kick or penalty should be awarded. It is common for players to stop fouls. The purpose of fighting for the ball is not to stop the ball, but to deliberately stop the opposite ball from running. Dangerous action refers to the action and kicking method of Zou, a player from both sides, which is considered by the referee to be in danger of hurting the other side or himself. If the purpose of blocking and dangerous actions is to get the ball or handle it, an indirect free kick should be awarded. In addition, the referee should master the favorable and unfavorable principles and try to avoid making a penalty in favor of the offending party. For example, the attacker shoots, and the defender who is not the goalkeeper touches the ball with his hand, but the ball still enters the goal. The referee should not judge the handball, but should judge the goal valid. At this time, if the referee judges the defending side, it may make the attacking side lose a chance to score. In this way, it may be beneficial to the offenders. Mastering the principles of advantages and disadvantages is an important symbol to measure a referee's penalty level. In a football match, players from both sides are allowed to collide reasonably, but they must collide with the same parts of the other side with parts below the shoulders and above the elbows within the control of both sides, and the elbows cannot be opened, and the collision intensity should be appropriate.

A direct free kick should be awarded for pulling, pushing, kicking, mixing, jumping against the opponent, dangerous collision and intentional handball in the game. If the defender makes the above-mentioned foul action in the restricted area, the other side shall be awarded a penalty.

In the game, if either side kicks the ball in a way that is in danger of hurting the other side, or blocks or collides with the goalkeeper who has no ball, an indirect free kick shall be awarded.

During the competition, the referee should give a yellow card warning to the coaches, team leaders or players who are at fault, hinder the competition, express dissatisfaction with the referee's penalty or have improper behavior; Those who behave badly or commit serious fouls and use foul language will be sent off with a red card and disqualified from the competition. The referee does not need to give any explanation to the warned person during the game, but he must write a written report and submit it to the organizer within the specified time after the game.
