Today children are often busier than adults, for they have to attend some classes such as dancing and art at weekends or in the holidays.
　　Parents think that their children will benefit from such classes. Firstly, with the development of today's society, competitionwill be more and more intense. So only the more versatile people will have bright prospects. Secondly, children will not waste their time playing games. Instead, they can gain some knowledge. Moreover, such classes can broaden their horizons.
　　However, I do not agree with the parents. Nowadays, many children have been deprived of their free time and become mechanical learners at the price of their own interest. I think children should have the rights to enjoy their childhood, and to play. In their spare time they can do what they want to do. Gradually they will discover what they are interested in and do their best in respective fields.
