Football, with the reputation of "the first sport in the world", is the most influential single sport in the world. In a standard football match, the two teams each send 10 players and 1 goalkeeper, * * *1/people to fight and attack on a rectangular grass court.
The purpose of the game is to shoot the football into the opponent's goal as much as possible, and you can get one point for each goal. When the game is over, the team with more points wins. If the score is the same within the specified time, it depends on the rules of the game. You can draw lots, play overtime or exchange penalties (12 yards) [1]? Equal forms of competition are divided into high and low levels. In the football match, except the goalkeeper can touch the ball with his hand in his own restricted area, each player can only control the football with other parts of his body except his hand (except the foul ball).
1. Venue area: the venue is rectangular, with a length of not more than 120m or less than 90m and a width of not more than 90m or less than 45m (the international competition venue is not more than10m or less than 100m and a width of not more than 75m or less than 64m). In any case, the length must exceed the width.
2. Line drawing: Draw clear lines according to the plan of the competition venues, with the line width not exceeding 12cm, and do not make V-shaped grooves. The longer two lines are called sideline and the shorter line is called goal line. Draw a line across the field in the middle? This line is called the center line. The center of the site should be clearly marked, and a circle with this point as the center and 9. 15m as the radius should be drawn, which is called the middle circle. At every corner of the site, a flat-topped flagpole with a height of not less than 1.50m should be erected, and a small flag should be tied to it. Similar flags and flagpoles can be erected at least outside the center line on both sides of the site: meters away.
3. Goal area: Draw a 5.50-meter-long line perpendicular to the goal line at both ends of the playing field 5.50 meters away from the inside of the goal post, with one end connected to the goal line and the other end drawing a line parallel to the goal line. The area within these three lines and the goal line is called the goal area.
4. Penalty area: On the goal lines at both ends of the playing field, at a distance of16.50m from the inside of the goalpost, the area within these three lines and the goal line is called penalty area, and the midpoint of the two goal lines is clearly marked, which is perpendicular to the field 1 1 m, which is called penalty area. Draw an arc outside the penalty area with the penalty spot as the center and 9. 15m as the radius, which is called penalty arc.
5. Corner area: Take the intersection of sideline and goal line as the center and 1 m as the radius, draw a quarter arc into the field, and the area within this arc is called corner area.
6.？ Goal: The goal should be located in the center of each goal line, and it consists of two vertical goalposts 7.32 meters away from the flag point in the west corner and at the same distance, and a horizontal crossbar with the lower edge 2.44 meters off the ground. In order to ensure safety, both the fixed goal and the movable goal must be stably fixed on the field. The width and thickness of the doorpost and crossbar shall be symmetrical and equal, and shall not exceed 12 cm. The net is tied to the goalposts, beams and the ground behind the goal. The net should be properly propped up so that the goalkeeper has enough room to move.
Note: The net can be made of hemp, jute or nylon. Nylon rope is ok, but it must not be thinner than hemp or hemp rope.
