这个短语的字面解释是“九日奇迹”，这是什么意思呢？请看对话：

    A: This singer is a nine days’ wonder. I doubt whether anyone will remember her in a year’s time.

    B: I totally agree. She shot to fame after appearing on a TV show, but she never had a song of her own.

    Note: The idiom refers to a novelty that loses its appeal after a few days. Some say it originated with William Kemp, an Elizabethan clown actor, thought to have been the original Dogberry in Shakespeare’s “Much Ado About Nothing.” He danced a morris dance between London and Norwich in 1600. He took up the challenge for a bet and covered the distance in nine days. But the phrase dates from well before the 17th century. And it isn’t “something wonderful that took nine days to achieve,” but “something which becomes boring after nine days.” People also cited a proverb as its origin: A wonder lasts nine days, and then the puppy’s eyes are open.
