英译汉:

Here's my advice to you: don't marry until you can tell yourself that you've done all you could, 
and until you've stopped loving the women you've chosen, until you see her clearly, otherwise you'll 
be cruelly and irremediably mistaken. Marry when you're old and good for nothing...
Otherwise all that's good and lofty in you will be lost.  

― Leo Tolstoy

这是我给你的建议：直到你已经做了所有你能做的，你已经不再爱你选的女人，并且你很清楚地了解她了，你再结婚，否则你将会犯残酷的不可挽回的错误。当你足够老并且已无可取之处时再结婚，否则你的好和高深都将会失去。

(托尔斯泰这建议也真是的哈，Please feel free to voice your opinion about it.  :)  )

汉译英:

第三次世界大战用什么武器我不知道，但是第四次世界大战肯定是用棍子和石块打的。

I don't know what kind of weapon they will use in WWIII, but sticks and stones will be used in WWIV for sure.

Idiom: Wrap sb's head around something   means :to understand a difficult idea

Example: My interview couldn't have gone much better, so I just can't wrap my head around how 
I didn't get the job. I must be missing something.
