Who knows the rules of curling and scoring?

Rules of Competition: The venue of curling competition is an ice track with a length of 44.5 meters and a width of 4.7 meters, which is kept very flat. Draw a circle with a diameter of1.83m at one end of the rink as the player's service area, which is called home plate. A circle is also drawn at the other end of the ice channel, which is called the camp. Inclined rubber pedals are installed at both ends of the curling ground. There is a solid blue line at the front and back ends of the court, which is called the avant-garde line and the defender line. After curling, if you don't enter the avant-garde line or cross the back line, it will be considered invalid and will be cleared out. In the curling competition, there are four people on each side. Players from both sides take turns throwing, and each player throws twice. The purpose of throwing is to make curling as close to the center of the camp as possible. The team that throws curling closer to the center of the circle than its opponent scores. Camp area is the division of curling competition. When 16 throwing is completed, it is a game. After one game, the next game continues from the opposite direction of the field, and the team that scored in the previous game throws first. Curling competition *** 10 game, 10 game, the team with the highest total score is the winning team. Competition skills: "Sweeping brush": A suitable "sweeping brush" should be able to melt the ice surface, turn the ice into a thin layer of water, reduce the friction between the "stone" and the ice surface, and make curling go far and straight. Ice surface: after the ice surface is as flat as possible, spray water droplets evenly on the ice surface. The bottom of curling glides on this "ice layer". Competition equipment: Curling equipment includes curling, competition shoes and brushes. Curling is made of mica-free granite in Scotland, with a standard diameter of 30cm, a height of11.5cm and a weight of 19. 1 kg. The players took part in the competition in special shoes. The soles of the two shoes are different in texture. One should be able to catch the ice and the other should be able to slide forward. The sole of the ice pedal is rubber, while the sole of the slipper is plastic. The ice brush adopts synthetic bristles or horsehair.

There are two teams participating in every curling competition. There are 4 people in each team. The game played 10 innings. Each player of the two teams throws twice per game (16 stone). The method is as follows: both sides of the game alternately throw 1 time in the order of first baseman, second baseman, third baseman and main force, and then make a second throw. Each game is judged by the distance between the stones of the two teams and the center of the base camp (also known as the camp). If the two stones of Team A are closer to the center than Team B, Team A will score 2 points. At the end of the game, the team that scored more points won. At the beginning of the game, the order in which the two teams throw stones is decided by drawing lots. Starting from the second game, the team that won the last game threw stones first. The curling ground is 44.5 meters long and 4.32 meters wide, and camps with a radius of 1.83 meters are drawn at both ends 3.66 meters away from the end line. There are avant-garde lines, T-lines and guard lines on both sides of the center line of the venue, surrounded by wooden frames 2 inches high and 4 inches wide. The stone is made of Scottish granite without mica, with a diameter of 29 cm, a thickness of 1 1.5 cm and a weight of 19 kg. Two teams participate in each game, each with four people. * * * 10 innings, each team player throws twice per inning (*** 16 stone). During the competition, each team is located behind the center line of its own camp. According to the order of 1 base player, 2 base players, 3 base players and main players, throw stones at each other alternately. The distance between the stone and the center of the opponent's camp is scored, each stone 1 point, and the one with more points wins. When throwing, the stone must cross the opponent's avant-garde line but not the back line, otherwise it will be disqualified. In the process of throwing, in order to make the stone slide farther and reach the target accurately, two members of the same team can hold a broom (or brush) and brush the ice vigorously from left to right before the stone batch runs. When the opponent throws, you can also sweep the ice in front of the stone in order to make the stone slide farther away from the center of the circle. In order to win the game, while trying to throw stones at the center of the circle, athletes can also knock the stones of the other team out of the camp or hit the stones of their own team under the command of the main players according to tactical needs.
