专业提示

区分'on and off'与'off and on'

两者在某些情况下可互换,但'off and on'更强调间歇性和不规律性,而'on and off'更强调偶尔性。例如:'She visits her parents off and on'(断断续续)vs 'She visits her parents on and off'(偶尔)。

黄金法则

避免字面翻译

切勿将'off and on'直译为'关闭和开启',应根据语境选择'断断续续'、'时断时续'或'间歇性'等中文表达。

词源

组合词,由介词off(结束)和连词and(和)+副词on(继续)构成。首次记录于16世纪初,原指机械设备的间歇运转,后泛化为描述任何不连贯的活动或状态。

用法说明

常用于描述天气、学习、工作等持续时间较长但不连贯的活动。注意与'on and off'(偶尔)在某些语境下可互换,但'off and on'更强调间歇性和不规律性。
