a different kettle of fish完全是另一回事

Clive, if you let yourself be defeated by them just because you are too fair to hit back the same way they hit at you, there won't be any methods but Nazi methods. If you preach the rules of the game while they use every foul and filthy trick against you, they'll laugh at you. They'll think you are weak, decadent. I thought so myself in 1919. I heard all that in the last war. They fought foul then and who won it? I don't think you won it. We lost it, but you lost something too. You forgot to learn the moral. Because victory was yours, you failed to learn your lesson 20 years ago. And now you have to pay the school fees again. Some of you will learn quicker than the others. Some will never learn it. Because you've been educated to be a gentleman and a sportsman in peace and in war. But, Clive... ... dear old Clive... ... this is not a gentleman's war. This time you are fighting for your very existence, against the most devilish idea ever created by a human brain. Nazism. And if you lose... ... there won't be a return match next year. Perhaps not even for a hundred years.

克萊夫，如果你只是因為太講公道，不肯用他們打你的方式回敬，就讓自己被他們打敗， 那剩下的就只會有納粹那一套。 如果你一邊講著比賽規則，他們卻對你使盡下三濫的招數， 他們會笑話你。 他們會覺得你軟弱、墮落。 1919年我自己也這麼想過。 上次大戰這些話我都聽過了。 他們那時候也打得下作，結果誰贏了？ 我看你們沒贏。 我們輸了，可你們也丟了點東西。 你們忘了從中吸取教訓。 因為勝利屬於你們，二十年前你們就沒學到那課。 現在你們又得再交一次學費了。 你們當中有些人會學得快些，有些人永遠學不會。 因為你們受的教育，就是要你們無論平時戰時都做紳士、做堂堂正正的運動員。 可是，克萊夫…… ……親愛的老克萊夫…… ……這不是一場紳士的戰爭。 這一次你們是在為自己的生存而戰，對抗的是人腦想出來最邪惡的念頭。 納粹主義。 而如果你們輸了…… ……明年不會有復仇賽。 也許一百年內都不會有。
