一段一两句，适合 5 岁。One or two short sentences per bit — age 5.
1商人要去集市卖布。马蹄铁上一颗钉子松了，他挥挥手：「小事，赶路要紧！」A merchant hurries to the market. One nail in the horseshoe is loose. He waves it off: "Tiny thing—speed matters!"
2半路轮子「咔嗒」一响，钉子掉了，蹄铁也歪了。马车只好慢慢挪，集市的钟已敲响。Halfway, the wheel goes "click." The nail falls, the shoe tilts. The cart creeps along; the market clock already rings.
3商人摸摸鼻子笑：「我省了半分钟检查，却晚了一整个上午。」他找来锤子，把钉子钉牢。The merchant rubs his nose and laughs: "I saved half a minute checking—and lost a whole morning." He fetches a hammer and sets the nail firm.
4下次出门，他先蹲下看一看：「钉子紧了吗？」车轱辘稳稳跑，他还提前到啦。Next trip he crouches first: "Is the nail tight?" The wheels run steady, and he arrives early.
