阅读下文：

不必说碧绿的菜畦，光滑的石井栏，高大的皂荚树，紫红的桑椹；也不必说鸣蝉在树叶里长吟，肥胖的黄蜂伏在菜花上，轻捷的叫天子忽然从草间直窜向云宵里去了。单是周围的短短的泥墙根一带就有无限趣味。油蛉在这里低唱，蟋蟀们在这里弹琴，翻开断砖来，有时会遇见蜈蚣，还有斑蝥，倘若用手指按住它的脊梁，便会拍的一声从后窍喷出一阵烟雾。何首乌藤和木莲藤缠络着，木莲有莲房一般的果实，何首乌有臃肿的根。有人说，何首乌根有像人形的，吃了便可以成仙，我于是常常拔它起来，牵连不断地拔起来，也曾因此弄坏了泥墙，却从来没有见过有一块根像人样。如果不怕刺，还可以摘到覆盆子，像小珊瑚珠攒成的小球，又酸又甜，色味都比桑椹要好得远。
