Over the last 40 years, there have been many changes in children's lives. I have four brothers and sisters. We used to play board games in the living room and spend days in the street with friends, and ride bikes to tour around the town.

These days, in the UK, great changes have been in the nature of childhood greatly. Firstly, families are getting smaller, as more families have only one child. It's common for both parents to work outside, and it seems that no one could possibly afford (付得起) to have more than one child. As a result, today's children spend much of their time alone. Another great change is that children today spend a lot of their free time at home. That's because parents worry about real or imagined dangers, so they wouldn't let their children play outside by themselves. Finally, the way children play is completely different. Almost every home has at least one computer and many children have a mobile phone. Mobile games have replaced (代替) board games and other interesting activities of my childhood. However, the fact is that playing mobile games alone can make people feel lonelier.

Do these changes mean that children today have a less relaxing childhood than I had? I believe that they do.
