I play a lot of sports such as soccer, volleyball, basketball, but my favorite one is soccer. It quite simple as the twenty two players of both team try to lead the ball into their opponent’s goal. However, there are some other rules that players need to follow in order to have a fair game. There is an offside rule which prevent players from running towards the opposite goal before anybody else. There is one main referee who has full authority to enforce the laws on the players. He has the power to stop the game temporarily to check on the players’ fault, to give a yellow or direct red card or to give a penalty decision. His decision is the final one, and nobody can argue about it even though he also has two or four other assistants. An international standard soccer field need to be 100 to 110 meters in length, and 64 to 75 meters in width. A domestic standard soccer field is a little bit smaller or bigger, which is 90 to 120 meters in length, and 45 to 90 meters in width in provided that it do not become square. A soccer match consists of two half of 45 minutes each, and there is a small break of 15 minutes before both teams entering the second half. If there is no goal in that official time, they need to play for another extra time, which consists of two other 15 - minute periods. If there is still no goal in that time, the players then enter the penalty shootouts. There are five times for each team to score, and the one with the most scores becomes the winner of the whole match. Soccer can be known as the king sport, and people will never stop playing it.
