A nine days' wonder
    曇花一現(xiàn)的人或事物
    A nine days' wonder means person or thing that attracts attention for a short time but is soon forgotten，曇花一現(xiàn)的人或事物。
    Wonder, one that arouses awe, astonishment, surprise, or admiration; a marvel，驚奇或詫異引起敬畏、驚異、驚奇或羨慕的原因；奇異之事。
    這里的nine days形容時(shí)間很短，并非表示“九天”這一具體的時(shí)間。
    我們來(lái)看例句：
    As a pop star she was a nine days' wonder: she only made one successful record.
    她是個(gè)曇花一現(xiàn)的歌手，只錄制過(guò)一張受歡迎的唱片。
