rehash

1. N-COUNT If you describe something as a rehash, you are criticizing it because it repeats old ideas, facts, or themes, though some things have been changed to make it appear new. 重复; 老调重弹[usu sing, N 'of' n] [表不满]

The critic found the play "a feeble rehash of familiar Miller themes."

评论家们认为这部剧“是大家熟悉的米勒式主题的拙劣翻版”。

2. V-T If you say that someone rehashes old ideas, facts, or accusations, you disapprove of the fact that they present them in a slightly different way so that they seem new or original. 只作轻微改动; 换汤不换药[表不满]

They've taken some of the best parts out of the best things and rehashed them. 他们提取了精华中的精华，然后对其稍加改动。
