Performed

分析词义

“Performed” 是 “perform” 的过去式/过去分词，可指“演出、表演”，也可指“执行任务、履行职责、运行（机器）表现如何”。

列举例句

“The band performed three encores.” (乐队加演了三首安可曲。)
“The surgery was performed successfully.” (手术成功完成。)
“The engine performed well in cold weather.” (这台发动机在寒冷天气下表现良好。)

词根分析

来自古法语 “parfournir”（完成），经拉丁语 “per-”（完全）+ “formare”（形成）演变为 “perform”。

词缀分析

“-ed” 为过去式后缀，加在动词 “perform” 之后。

文化背景

职场评价常说 “performed above expectations”（超出预期）；艺术语境中 “live performed” 强调现场演出。

单词变形

固定搭配: “performed poorly” (表现不佳), “performed live” (现场演出), “performed duties” (履行职责)
原形: perform；现在分词: performing；名词: performance

记忆辅助

perform + ed = performed：已经完成的 perform 就是 performed。

助记故事
