     Each nation has many good people who help to take care of others. For example, some high school and

college students in the United States often spend many hours as volunteers in hospitals, orphanages or homes

for the aged. They read books to the people in these places, or they just visit them and play games with them

or listen to their problems.

     Other young volunteers go and work in the homes of people who are sick or old. They paint, clean up, or

repair their houses, do their shopping or mow their lawns. For boys who no longer have fathers there is an

organization called Big Brothers. College students and other men take these boys to baseball games or on

fishing trips and help them to get to know things that boys usually learn from their fathers.

     Each city has a number of clubs where boys and girls can go to play games or learn crafts (手艺). Some

of these clubs show movies or organize short trips to the mountains, the beaches, museums or other places

of interest. Most of these clubs use a lot of high school and college students as volunteers because they are

young enough to remember the problems of younger boys and girls. Volunteers believe that some of the

happiest people in the world are those who help to bring happiness to others.
