moment, instant, minute, second, jiffy, flash- These nouns denote a brief interval of time.Amoment is an indeterminately short but not insignificant period: 这些名词意思是短暂的时间间隔。Moment 是指不确定地短暂而不是非常短暂的一段时间： I'll be with you in a moment.我过会儿就和你在一起。It took him a moment to answer.他很快就回答上了。

- Minute andsecond, used strictly, refer to measured intervals of time;often, though,minute is interchangeable with moment ( Minute 和second 严格地用， 是指测得的时间间隔；但是通常minute 和 moment 可以互换（ Wait a minute.等一会儿。The plane will be arriving in a minute), andsecond with instant ( 飞机再过一会儿就要到达了)， 而且second 可以和 instant 互换( I slipped out of the room for a few seconds to turn the oven on). 我溜出房间一会儿去打开炉子)。
- Jiffy andflash occur principally in combinations preceded by in a; in a jiffy means in a short space of time,whilein a flash suggests the almost imperceptible duration of a flash of light: Jiffy 和flash 主要出现在前面有 in a；in a jiffy 的组合词里， 用来指短暂的时间，而in a flash 指一闪或一亮的、几乎难以察觉到的时间持续： "He was on his stool in a jiffy, driving away with his pen" (Charles Dickens). “眨眼间他坐到了凳子上，用他的钢笔奋力工作” （查尔斯·狄更斯）。 She was on her feet in a flash when the doorbell rang.
