“可付之一笑的”可以翻译为 “worthy of a laugh” 或 “something that can be dismissed with a laugh” 。
“worthy of a laugh” 表达某事值得一笑，带有一种轻松看待、不必太在意的意味；“something that can be dismissed with a laugh” 则更具体地描述出这件事可以用一笑来打发、不予过多关注 。例如：His silly mistake is worthy of a laugh.（他犯的这个愚蠢错误可付之一笑。 ）/The whole incident was something that could be dismissed with a laugh.（整个这件事可付之一笑。 ）
