Are you looking for something fun? Would you like to help other people in your free time? Then join us and be a volunteer(自愿者).

We have volunteer jobs for people of all ages. Anyone, between the age of 12 and 80, can become a volunteer.

You can help people in many ways. Nursing homes need volunteers to take care of old people. 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 homes. There is something that out volunteers want to tell you.

“As a volunteer, I don’t want to get anything. Seeing the children’s happy faces, I am happy, too.” said Carlos, an old woman of 62.

“ I often played computer games in my free time before. Now I help middle-aged people learn how to use computers.” said another volunteer at the age of 18.

If everyone gives a hand, we’ll have a better world to live in.
