Children today would rather toy with new technologies. The role of children has changed as well as that of teens. The world has truly evolved (进化）throughout the years.
Today，a typical day in the life of a five year old is entirely different from what it once was. A few decades ago children used to work. They did the kind of work parents do today. Today there are shows on which children are putting pounds of makeup on and have flashing things all over their bodies. This makes a child want to paper over all of their imperfections. They think they have to look perfect all the time.
Teens have changed as well. My grandma got married when she was thirteen. Girls who had an arranged marriage had no time to play because they were expected to cook, clean，take care of the kids, and do housework every single day. Today，we go to school every morning, maybe participate in some after-school activities, and possibly go to work for extra cash. Then we go home and do homework, and eat. After all of this we have to find the time to socialize by texting, talking on the phone, or logging on to social networking sites. We enjoy ourselves a lot.
The generation before us complains about how they did not have the things we have now. They say we are not appreciative and do not value life or just do not care about our futures anymore. Let's make a change! The youth have the power to work on whatever they believe in and make a difference in the world. Take advantage of your resources. It is never too late to make a positive change in our world.
