Moon就是“月亮”，ask for是“要求”。这个短语是什么意思呢？请看对话：

    A: Sophie was not quite her usual happy self yesterday. Do you know what happened?

    B: She went to talk with the boss yesterday, asking for a two-week holiday.

    A: And the boss said no?

    B: Of course he said no. She’s asking for the moon at this time of the year, when everyone is busy dealing with holiday sales.

    Note: This idiom means to make outlandish requests or demands for something, such as a lot of money or special privileges. It’s easy to understand that small children who have no idea what moon really is may ask for the bright beautiful satellite as a new toy. Of course, this is impossible. Other idioms involving “moon” include: to shoot for the moon (very ambitious), once in a blue moon (very, very rarely) and casting beyond the moon (to make wild speculations).
