Are you looking for something fun and would you like to help other people in your spare time? Then join us to be a volunteer. We are a non-profit organization(非盈利组织).We have volunteer jobs for people of all ages. Anyone from 12-year-old children to people in their seventies can become a volunteer.

You can help people in many ways. Schools need help with taking care of children while their parents are working. Hospitals need volunteers to look after children while their parents see a doctor. Animal lovers can help take care of those dogs and cats without houses. There is something for everyone.

“As a volunteer, I don’t want to get anything. Seeing the children’s happy faces, I’m happy, too.” said Carlos Domingo an old woman of 62. “I often help older people learn how to use computers.” says another volunteer at the age of 18.

If everyone helps out a bit, we’ll have a better world to live in. Interested? Call us at 1-800-555-5756, or visit our website:www.activol.com.
