我童年的摇篮,少说也被几百万只青蛙摇动过。

②小时候刚学会走路,在泥土的田埂上摔了多少跤?我趴在地上,哭着,等大人来扶,却看见一些虫儿排着队赶来参观我,有的还趁热研究我掉在地上的眼泪的化学成分。

我扑哧一笑,被他们逗乐了。

我有那么好玩,值得他们研究吗?于是我静静地趴在地上研究他们。

当我爬起来时,我已经有了我最初始的昆虫学。

摔跤,原来是我和土地举行的见面礼:你必须恭敬地贴紧地面,才能接受土地最好的生命启蒙。

③现在,在钢筋水泥浇铸的日子里,你摔一跤试试?你跌得再惨,把身子趴得再低,也绝然看不见任何可爱的生灵,唯一的收获是疼和骨折。

④稻田与荷田,只隔着一条田埂,他们是一对上千年的老邻居,是芳邻。
