In fact,I often think of this problem,whenever I see a beggar,I feel so guilty,for I can't help them,I am just a senior high school student,and what's more,my classmates usuallysay the world is dark,it is so realistic,in his opinion,do his own things well is OK,but I don't think so ,if I have a chance in the future,I will change it ,i will do my best to help the poor people .
