a little bird told me是一種非常詼諧的表達(dá)，意思是“有人告訴我”, 當(dāng)你不想透露某個(gè)消息是誰(shuí)告訴你時(shí)，就說是a little bird told me...

這個(gè)說法有個(gè)典故：在《圣經(jīng)》里，人類祖先躲在諾亞方舟里，為了看洪水是否退去， 就派了一只鳥兒去打探，所以a little bird就演變成了消息靈通的人士了。

said if you know who gave you the information being discussed but do not want to say who it was

你知道告訴你信息的這個(gè)人，但是不想告訴別人他是誰(shuí);無(wú)可奉告，我不說

A; How did you know he was leaving?

你怎么知道他要走了?

B: Oh, let's just say a little bird told me.

噢，有人告訴我的。
