南半球有一个独占整个大陆的国家是____．

    "All work and no play makes Jack a dull boy" is a popular saying in the USA．It is true that all of us need recreation (娱乐). We cannot work all the time if we are going to keep good health and enjoy life.

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

    Not everyone who enjoys sporting events likes to take part in them. Many people like watching TV or listening to them on the radio. So many people like forms of indoor recreation, such as watching TV, singing and dancing.

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