Now more and more students become volunteers. The projects may be with their school, neighborhood, or town, but the work of all volunteers is important. Students find that there are many advantages to volunteering.

First, volunteering helps others. Many people complain about problems in our society. Volunteers are part of the solution to our problems! While it is easy to complain about things that are not right, the volunteer takes action rather than complaining. When a student spends time working at a retirement (退休) home, cleaning up a park, or teaching a younger student, the volunteer makes the world a better place.

Second, being a volunteer makes students feel good about themselves. When a student volunteer knows that his or her efforts have made someone else’s life better, the volunteer feels great. Students always hear people saying that everyone should care about other people. Volunteers make it happen. Although some volunteer work is long or tiring, student volunteers end the day knowing they did the right thing. Their parents, teachers, and the public are proud of them. Knowing they did the right thing makes them feel better, even if they are tired.

Finally, students learn that volunteering is fun. A group of students might volunteer to clean up a riverbed in early spring. It is fun to be with their friends, to enjoy the weather, and to picnic later in a beautiful, clean area. Other students might read to young children in a playgroup. It is fun to spend time with children and to have them smile and laugh. No matter what their ages or talents are, every student can be a volunteer. The work of student volunteers is a powerful force that makes the world a better place.
