As a stranger entered a little country store， he noticed a sign warning， “Danger！ Beware of dog！” posted on the glass door. Inside， he noticed a harmless①old hound dog asleep on the floor beside the cash register②.“Is that the dog folks are supposed to beware of？” he asked the owner.“Yep， that’s him.” came the reply. The stranger couldn’t help but be amused.“That certainly doesn’t look like a dangerous dog to me. Why in the world would you post that sign？”“Because，” the owner explained， “Before I posted that sign， people kept tripping③over him！”

小心有狗
一名陌生人走进一家乡间小商店，看到玻璃门上帖着的一个告示牌上写着，“危险！小心有狗！”进去后，他看到一条样子一点都不凶的老狗趴在收款机旁边的地板上睡觉。“这就是大伙都得留神的那只狗啊？”陌生人问店主。“是，就是他。”店主回答。听到这个回答， 陌生人觉得很好笑。“我觉得那条狗一点都不可怕。你帖那个告示做什么？”“因为，”店主解释说，“在我帖告示之前， 大伙老被他绊倒！”
