having been a volunteer of the EXPO for over twenty days,i really have learned a lot.many people treat voluntary service as a tired task.well,I have the same feeling.after the past several days,with the hot sun shining and rain shedding and winds blowing,i believe nobody would deny the tiredness of this job.everyone of us who volunteered in the EXPO worked hard every day and tried our best to contribute,with our youth and our limited power.
