短語to ask for the moon直譯是要天上的月亮，實際意思是說某人提出過分的要求，想要得不到的東西或是想做做不到的事兒。
例句：
Bob's wife is always asking for the moon. He works hard 12 hours a day for poor pay, but she still expects expensive holidays and clothes.
Don't ask for the moon, Mr Jones. Be reasonable, please.
注意：
短語to promise the moon to someone的意思是向某人答應(yīng)辦不到的事兒，也就是漢語里常說的空口許愿。
例句：
My husband promised me the moon when we got married: a big mansion, a flashy car and all the diamonds I could wear. But none of it happened!
常識補充：
The Apollo missions between 1969 and 1972 returned over 380kg of rocks from the Moon, which have been used to help us understand its origins and structure.
從1961年到1927年，美國的阿波羅計劃從月球上取回了380多公斤的巖石標(biāo)本。這些帶回來的標(biāo)本對研究月球的起源和構(gòu)造有很大幫助。
