英语词源
over the moon非常高兴，欣喜若狂
该短语形容某人欣喜若狂。如：
She was over the moon when he asked her to marry him.
当他向她求婚时，她欣喜至极。
这一表达方式至少可追溯至18世纪传统童谣蔚为大观之时，例如下面这一首：
Hey Diddle Diddle,
The cat and the fiddle,
The cow jumped over the moon.
The little dog laughed,
To see such sport,
And the dish ran away with the spoon.
稀奇，稀奇，真稀奇，
小猫拉着小提琴，
母牛跳过了月亮，
小狗看到哈哈笑，
碟子带着汤勺跑走了。
