2010年2月1日,又是一年学期末,当“贫困寄宿生生活补助”下来的时候,班主任又喜又忧。喜的是,这生活补助能帮助贫困学生及其家庭解决一些实际问题;忧的是,这里毕竟是艰苦的国家贫困边远山区,贫困家庭太多,贫困孩子太多,班上就有60多个孩子需要这种帮助,而名额只有30个,如何分配可真是一个难题。针对生活补助名额分配,曾玲珠同学举起了手,她有什么好的建议呢?“老师,我不要补助,把补助给更需要帮助的人!”她居然拒绝补助,她可是家庭特困的孩子呀,大家都将惊讶和不解的目光投向了她。只听她说:“因为我已经长大了,能够自立了,能够自己挣学费和生活费了!”迎着大家惊奇的目光,她慢慢地说出了自己的理由:“我每天可以在校园里收拾同学们用过的作业本和喝完的矿泉水瓶,旅假回家后可以在集镇帮助推销商发放宣传单,一学期下来,要挣好几百块啦,这已经够我的学费了。况且我和哥哥还可以春夏间挖笋子、摘板栗、猕猴桃等,一年也可以挣到两三千元钱。”
