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.

克莱夫，如果你只是因为太讲公道，不肯用他们打你的方式回敬，就让自己被他们打败， 那剩下的就只会有纳粹那一套。 如果你一边讲着比赛规则，他们却对你使尽下三滥的招数， 他们会笑话你。 他们会觉得你软弱、堕落。 1919年我自己也这么想过。 上次大战这些话我都听过了。 他们那时候也打得下作，结果谁赢了？ 我看你们没赢。 我们输了，可你们也丢了点东西。 你们忘了从中吸取教训。 因为胜利属于你们，二十年前你们就没学到那课。 现在你们又得再交一次学费了。 你们当中有些人会学得快些，有些人永远学不会。 因为你们受的教育，就是要你们无论平时战时都做绅士、做堂堂正正的运动员。 可是，克莱夫…… ……亲爱的老克莱夫…… ……这不是一场绅士的战争。 这一次你们是在为自己的生存而战，对抗的是人脑想出来最邪恶的念头。 纳粹主义。 而如果你们输了…… ……明年不会有复仇赛。 也许一百年内都不会有。
