【一句话翻译】千万别结婚 ：）

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

(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。

Idiom: Wrap sb's head around something

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.
