    In the world today, all of the people need to have fun when they are free. We can't work all the time if we are going to keep healthy and enjoy life.

    Everyone has his own way of relaxing. Perhaps the most popular form (形式) is to take part in sports. There are team sports, such as basketball and football. There are also individual(个人的) sports, such as swimming and running. Skating and mountain climbing are the most popular recreation (消遣) for people who like to be outdoors.

Not everyone who enjoys sports likes to take part in them. Many people like watching them on TV or listening to them on the radio. So many people like some indoor relaxation, such as watching TV, singing and dancing.

    It doesn't matter if we like indoor recreation or take part in outdoor sports. It is important for everyone to relax from time to time, and enjoy some themselves.
