1 "All work and no play makes Jack a dull boy" is a popular saying in the United States. Other countries have similar sayings. It is true that all of us need recreation. We cannot work all the time if we are going to maintain good health and enjoy life. Good physical and mental health in fact enables us to work more efficiently.
2 Everyone has his own way of relaxing. Perhaps the most popular way is to participate in sports. There are team sports, such as baseball, basketball, and football. There are individual sports, also, such as golf and swimming. In addition, hiking, fishing, skating and mountain climbing have a great attraction for people who like to be outdoors. Chess, card-playing, and dancing are forms of indoor recreation enjoyed by many people.
3 Not everyone who enjoys sporting s likes to participate in them. Many people prefer to be spectators, either by attending the s in person, watching them on television, or listening to them on the radio. When there is an important baseball or boxing match, it is almost impossible to get tickets; everyone wants to attend.
4 It doesn’t matter whether we play a fast of ping-pong, concentrate over the bridge table (桥牌桌), or go walking through the woods on a brisk (清闲的) autumn afternoon. It is important for everyone to relax from time to time and enjoy some form of recreation.
