But if you are like the other 10 percent, you are an outie!

但如果你像其他10%的人一样，你就是凸脐人！

Outies look like a small raised part of the skin.

凸脐看起来就像皮肤的一小块凸起。

The 411 was a 911, meaning I had to outie 5000.

原来是有急事找我，也就是说，我不得不离开。

Are you an 'innie' or an 'outie? '

你是‘凹脐人’还是‘凸脐人’？

But rivers don't have umbilical cords, so why do they have innies and outies?

但是河流又没有脐带，那它们为什么会有凹凸的区别呢？

But in general, belly buttons have two basic different shapes: 'innies' and 'outies.'

但一般来说，肚脐有两种基本不同的形状：凹脐和凸脐。

The same can't be said for all the world's outie belly buttons.

当然，这不适用于世界上所有外凸型河道。

People used to believe that a doctor could cut the umbilical cord of a baby to shape it into an innie or an outie.

人们曾经相信，医生切断婴儿脐带的手法，可以决定是凹脐还是凸脐。

Rivers also have innies and outies, not belly buttons, but mouths: where rivers flow into the sea, the land either pokes out or bends inward.

河流同样也有凹凸之分，不过不是肚脐，而是河口：在河流入海的地方陆地会向外延伸，或者向内弯曲。

It forms when a doctor snips your umbilical cord, and, depending on how it heals, you could have an outie or, more likely, an innie.

它是由医生剪断你的脐带时形成的，根据脐带的愈合情况， 你可能会出现外脐，或者更可能是内脐。

Thus the world's great outie river-mouths the fertile deltas like Nile and Yangtze that have helped foster human civilization since its birth all came into being at just about the same time.

因此，世界上许多大型的外凸型河口及其富饶的三角洲（如尼罗河和长江）从诞生起就促进了人类文明的发展，并且几乎都是在同一时间形成。
