| 词汇 | make things hum |
| 词源 | make things hum. Since at least the early 18th century, hum- ming, suggesting the blending of many human voices or the ac- tivity of busy bees, has been used to express a condition of busy activity. Two hundred years later the expression to make things hum was invented in America. Possibly the hum of machines in New England textile factories was the inspiration for the phrase, in reference to the fabled Yankee mechanics who made things hum again when the machines broke down. |
