Dear Wang Lin,
I am a volunteer in Saving the F,nvironment Club of my school.  Last Saturday, I did some volunteer work with other voluriteers.Some of us put up posters. Some handed out notices.Others swept the streets. We also helped clean up the city parks. When we finished all the. work, we were very tired but felt very happy at the same time.I think it:s great to be a volunteer.What do you think of volunteering? Please write backsoon !
Yours,
Tom .
