请看几年前《中国日报》的一篇相关报道：The latest publicity feast in director Feng Xiaogang's not-yet-completed "The Banquet" is the issue of Zhang Ziyi's nude scenes in the blockbuster film. Now a woman who says she was Zhang'sstand-inwants credit where credit is due.

Actress Shao Xiaoshan said she substituted for Zhang in some bathing and sex scenes. However, she is not listed in the credits.

如果仔细阅读报道中的两段文字，即使不熟知“stand-in”，您也会在随即出现的“substitute”中猜出它的大致意思“替身，代替”。Stand-in（替身）源于动词词组“stand in for”（暂时代替某人），例如：I'm standing in for the regular man while he's on holiday.（那位正式职员休假了，由我暂时顶替他的职位。）

在这里，顺便提一下我们之前讲过的stuntman（特技表演者），stuntman也可做“替身”，不过更强调“身怀绝技、有某种特异功能”的替身演员。
