我们直接进入主题，live on air 是什么意思？意思是：人活在空气中？

    当然不是，真正的意思是：喝西北风

    人们常用“喝西北风”来表示“没有收入来源，

    只能挨饿”，在英语中用live on air表示。

    Out of money, John had to live on air.

    没钱了，约翰要靠喝西北风度日了。

    例句：

    A:I lost my job and have to live on air now.

    我丢了工作，现在只能喝西北风了。

    B:Cheer up! I can help you.

    振作起来！我可以帮你。

    “喝西北风”也可以用来形容“没饭吃”

    所以还可以表示成have nothing to eat

    例句：

    The family had nothing to eat since the father lost his job.

    因为父亲失业，

    全家只能喝西北风了。
