若是遇到什么復雜情況，長輩們常常囑咐我們要“見機行事”，“抓住了機會”就好辦事，要是錯過了機會，就只有慨嘆“痛失良機”了。
抓住機會：jump at the chance
Jump at the chance 的意思就是“（迅速地）抓住機會”，跳起來抓，是夠迅速的。
比如：When the lead singer became ill, Sheila jumped at the chance toreplace her.
這個片語還有個很形象的變體，就是jump at the bait，看見有好處就跳上去了。
比如：They offered a large reward, hoping that someone would jump at thebait.
另外，jump at 也可以表示“抓住……”，通常是有好處的事情。
例如：When Dad said he'd help pay for my vacation, I jumped at the offer.
