Play-游乐
Play is an important part of life. Some people ever think that the purpose of life is play. Most Americans spend their holidays playing and more people come to believe that play is the lubricant of life. Open the newspaper, and you will see a great deal of news about movies, concerts, art exhibitions, television programs and all kinds of sport events. Indeed, if you will just step outside, you will see people heading for the park for picnic or taking their children to the zoo. During the weekend, life is play.
