It is all Greek to me.这我完全不懂。

be Greek to sb.不为某人所理解；不懂

出自莎士比亚剧本《裘力斯·恺撒》。

Did Cicero say anything?

CASCA  Ay, he spoke Greek.

CASSIUS  To what effect?

CASCA  Nay, an I tell you that, I’ll ne’er look you i’ th’

face again. But those that understood him smiled at

one another and shook their heads. But for mine

own part, it was Greek to me.

凯歇斯

西塞罗说了些什么?

凯斯卡

嗯，他说的是希腊话。

凯歇斯

怎么说的?

凯斯卡

嗳哟，要是我把那些话告诉了您，那我以后再也不好意思看见您啦；可是那些听得懂他话的人都互相瞧着笑笑，摇摇他们的头；至于讲到我自己，那我可一点儿都不懂。

我们看个例子：

It is all Greek to me.这我完全不懂。

The computer language is all Greek to me.

我对计算机语言一窍不通。
