莫肯人

莫肯人一年中有8个月的时间在船上度过。

The Moken spend eight months of the year on boats or stilt houses .

因此，他们能够轻易分别出水下的蛤和石块，获取食物。经过试验，莫肯人孩童的水下视力是欧洲孩童的两倍。

Thus , they can easily distinguish between edible clams and ordinary rocks even when many meters below water.When tested , the Moken children had underwater vision twice as sharp as European children .

不过，这似乎是每个人都能够拥有的能力，只要我们改变环境，同样也会产生相应的变化。研究者们训练欧洲孩童向莫肯人孩童一样在水底不停地作业，最终成功地证明了这点。

However , it seems that this is an adaptation that we might all possess if our environment demanded it , since researchers have trained European children to perform underwater tasks as successfully as the Moken .

这就使得当我们得知莫肯人能够在水下（甚至是22米深的水下）将事物看得一清二楚时感到吃惊不已。

That knowledge makes it all the more surprising that a group of people , known as the Moken , have the ability to see clearly underwater , even at depths up to 22 meters ( 75 ft ) .
