生活中，我们经常遇到一些耳熟能详，甚至习以为常的词汇，却不知道英文中有没有相应的地道表达。因此，中译君邀请中译公司战斗在翻译市场第一线的资深译员，每天和大家分享一个常用词汇的英语表达。

看过之后你可能会发现：哎哟，这个表达竟然和我想的完全不一样耶！

实践出真知

The proof of the pudding

(is in the eating)

释义：

The real value of something can be judged only from practical experience or results and not from appearance or theory.

实践出真知，试过才知道。

例句：

Everything, though, depends on whether Musk and his colleagues can deliver on their promise of a tunnelling technology that cuts the dizzying cost of installing new light rail or underground train tracks. Musk himself called this “the proof of the pudding”.

新闻背景是马斯克又搞了项新技术，号称能将现在的隧道挖掘效率提高十五倍，所以以后不但可以送大家去火星还能去地心。

有意思的是这家新公司叫The Boring Company，这里的boring是bore的动名词形式，tunnel-boring 挖隧道，The tunnel-boring technology is a boring technology.
