There are always some helpful people who take care of others as volunteers. For example, some high school and university students often spend many hours volunteering in hospitals, orphanages(孤儿院) or old people's homes in their free time. They read books or the newspapers for the sick people, play games with them and tell jokes for fun. Other young people volunteer to help some old people. They help paint, clean up, repair their houses or cut the grass.
To help teenagers, there are a number of clubs where boys and girls can go to play games or learn some skills. The clubs often offer the problem teenagers some chances to watch movies or have short trips to the mountains, the beaches, museums or other places of interest. Most volunteers there are high school and college students because they are young enough to remember the problems of younger boys and girls.
The volunteers always get excited about helping others. The volunteers help make people less worried and forget their problems and understand the happiness in their life. They say they can learn a lot from the experiences. The volunteers also believe that the happiest people in the world are those who help to bring happiness and kindness to others.
