And one reason we know this

我们之所以这样认为
is because of the demonstrated case studies

是因为有许多的个案研究
where a language is created within a single generation.

都证明了一代人之内是可以创造出语言的
And these case studies have happened over history.

这些个案研究曾在历史上得到多次验证
The standard example is people involved in the slave trade.

典型案例就是奴隶交易中的人们
The slave trade revolving around tobacco or cotton

为了获得烟草棉花
or coffee or sugar

咖啡或糖块的奴隶交易
would tend to mix slaves and laborers

会将来自不同语言背景的奴隶
from different language backgrounds,

和劳动者们混在一起
in part deliberately,

这也在某种程度上
so as to avoid the possibility of revolt.

谨慎地避免了可能的造反
What would happen is these people who were enslaved from different cultures

这些来自不同文化的被奴役的个体
