"一刻钟"在英语中表示为 "a quarter of an hour"。
"一刻钟"的来源是 "quarter hour" 的简写，"quarter" 意为 "四分之一"，"hour" 意为 "小时"。因此 "a quarter of an hour" 就表示 "一刻钟"。
例句:
I will be back in a quarter of an hour. (我会在一刻钟之后回来。)
The meeting will start in a quarter of an hour. (会议将在一刻钟后开始。)
It takes a quarter of an hour to walk to the station. (步行到火车站需要一刻钟。)
