　　峰子最后还是选择了回家乡教书。当同学们都去火车站送他时，峰子不知怎的就想起了一句悲壮的古诗：壮士一去兮不复返。

　　先到县教育局报到，签了字后，办公室的同志瞪着一对金鱼眼问：“你是师大毕业的？”峰子什么话也没说，背起两大袋子书和行李，头也不回地搭车回了家。

　　父亲见峰子回来了，远远地迎了上去，说：“工作好了吧？”

　　峰子没吱声，把行李往父亲手上一放，回到家“咕嘟咕嘟”喝了一大杯水，然后才说：“省晚报让去做记者，没去。”

　　“怎么？”

　　“我想回村里学校教书。”

　　父亲颤着声问：“是不是在学校里犯了事？”

　　“年年都评三好学生呢，怎会犯事？”峰子坐了下来。

　　“那怎么回咱这破村？”

　　“学校不是少了老师么。”

　　【A】父亲愣了好一阵，叹了口气，便去张罗着煮面条。

　　峰子早没了娘。他看着驼了背的父亲，心中不由惴惴不安：父亲要是骂他一顿，或者打他一记耳光，他的心里也许会好受一点。

　　吃过面，峰子便去村小学找校长。

　　【B】说是学校，其实不过一层四间的茅草土坯屋，屋旁竖着一根四五米高的木杆，上头飘着一面早已发白的旗。学校长年驻校的，也就校长一人。

　　峰子在学校的自留地上找到了校长，校长正戴着那副掉了一条腿的老花眼镜，在地里侍弄自己种的蔬菜。

　　峰子轻轻地唤了一声：“校长。”

　　校长回过头，眼镜差点儿就掉到了地上。他见了峰子，脸上的笑便浮了上来，说：“峰子回来了。”

　　“我是来向您报到的，我也来学校教书，以后我就是您的部下了。”

　　“你……”【C】校长什么话也说不出来，只是汪了泪，顾不上擦掉泥巴，就紧紧地握住峰子的手。

　　校长破例炒了一盘蛋，邀峰子喝一盅。校长一边喝酒一边说：“想你考上大学那年，学校里的娃儿就加了一倍，大家都把你当榜样呢。”

　　峰子就想起往年的寒暑假，他一回家，总有东家西家的请他到家里吃饭教课，说是要自家的娃子学学他的样。

　　可是，这一年暑假过去，也没见哪家有人来请他。和乡里乡亲的见了，还有人不相信地问：“峰子，你真回咱村里教书？”

　　峰子就爽快地回答：“是！”

　　到秋天开学了，报到的学生竟暴减到了往常的三分之一。校长和峰子都不明白：老师多了，学生怎么反倒少了？

　　于是峰子拿了一份花名册挨家挨户去问，问来问去，都回答说，我家娃儿不念书了，过两年让他到外面打工去。

　　峰子说：“孩子还小，怎就不让念了？”

　　“念了书没用。”

　　“怎没用？念了书可以考大学啊。”

　　对方就不吭声了，任峰子怎么劝说也没用。等峰子一脚跨出大门，【D】后边就传来轻轻的嘀咕：“________________________。”

　　这话刺得峰子的心一阵阵地疼。

　　一年后，县教育局捎了信过来，说是让峰子去领“扶贫助学志愿者”奖章，他成了全县教师的榜样呢……（选文略有改动）
