I would like to be a volunteer.what kind of volunteer I'd like to be.I think it should be traffic safety volunteer.Because i think traffic safety is a common topic everyone talks about everyday.But there is still some people who don't have strong sense of traffic safety.I hope i could make a contribution to our society and increas the public"s awareness of safety.If one person wants to go across the road with the red traffic light ,I will persuade him give up the dangerous behaviour.
