Most people agree that children should have plenty of time to play ，yet what do we do about it? We refuse to pay attention to the fact, and we forget all about it, because we think play is a waste of time. We try to build a large city school with many classrooms and expensive equipment (设备)for teaching, but give only small space for children to play. They have not enough play fields for organized games, such as football or basketball. Organized games need skill ，competition and team work. It is true that small children like to play games of soldier and enemy with shooting(射击).These games are very often learnt from films. But long before the film age, children played such games ― running after another in order to catch him.
