德萊塞《美國(guó)的悲劇》：

Seeing and doing are two entirely different things.?

看人家做和自個(gè)兒做，完全是兩回事。

原文：

“Not the same thing. Not the same thing,” insisted Gilbert sharply. “Seeing and doing are two entirely different things. A person without any experience can think a lot, but when it comes to doing, he’s not there. Anyhow, this is one business that requires people who do know.”

“不一樣，不一樣。”吉爾伯特一個(gè)勁兒厲聲說(shuō)。“看人家做和自個(gè)兒做，完全是兩回事。沒(méi)有什么經(jīng)驗(yàn)的人可以想得很多很多，可是一做起來(lái)，就什么都不行了。反正不管怎么說(shuō)，這個(gè)工作就是需要真正懂行的人。”
