答案：Some of them seem meaningless, but they are quite eye-catching and often bring people a knowing smile.。略解：「看似無意義」譯為seem meaningless（系表結構正確）；「引人注目」用eye-catching（形容詞作表語，符合英文習慣，避免誤譯為attract people's eyes）；「會心的一笑」為a knowing smile（固定搭配，knowing表「心照不宣的」，避免誤譯為an understanding laugh）；用but體現轉折關係，and連接「引人注目」與「帶來會心一笑」，語法完整，語意達意，符合中譯英「準確、通順」要求。 報錯 ChatGPTDeepSeek
