one-horse（adj.）
"小规模的，琐碎的"，1853年，美国英语，口语，指城镇； 见 one + horse（n.）。可能源于早期用于指马车、雪橇、犁等“由一匹马拉动”的用法（1750年）； 也指“只有一匹马”的农民； 因此，“琐碎的，小规模的，资源有限的； 低劣的”。
Shortly afterwards I took a stroll over the town. It was what is generally denominated a "one horse town," and I would think a pretty small pony at that. Two stores, one grocery, a stable, and four dwellings made up the sum of its buildings. ["Daguerreotyping in the Back Woods," in Yankee Notions, March, 1855]
不久之后，我在镇上散步。它通常被称为“一匹马的城镇”，我认为那只是一匹相当小的马驹。两家商店，一家杂货店，一个马厩和四栋住宅构成了它的建筑总数。["Daguerreotyping in the Back Woods," in Yankee Notions, March, 1855]
