what kind of volunteer work do you take part in?How useful is the volunteer work to you?

Last summer, I and my classmate went to the countryside to do volunteer activities. First, I taught children english and other subjects. We helped them played some games, it was funny. Then, we helped farmer collect their harvest. Some of us planted trees along the street and cleaned the village. I think last summer was very intereting because we have helped poor people. I love this avtivities.
