English has morphed into several other languages all over the world.

英语已经演变成世界各地好几门其它语言。

Languages are ever changing, mixing and mutating, and sometimes they give birth to new ones.Three important factors linguists have identified in languages giving birth to other languages are time, separation, and contact.

语言一直在变，有混合、有演变，有时候还会产生新的语言。语言学家发现语言产生语言的三大因素为时间、分离和联系。

All languages change with time, as speakers innovate and economise.This does not quickly make a new language, but it can over time.

所有语言都随时代而变，说语言时人们精简话语、有所创新。语言不是一蹴而就的，需要时间。

Separation – geographical distance, cultural divergence, political independence – helps give a changed version of a language an independent identity.

分离，即地理上的距离、文化分化和政治独立，给了语言独立的省份。

Contact with other languages is a very important force: mutual influence leads to borrowing of words and even grammatical structures.

和其它语言的交流也是很重要的因素：相互影响引发借用其它语言的词汇、乃至语法结构。

Sometimes a simplified version is created for the purposes of trade, often using simplified grammar mainly from one language and adapted words from mainly from the other.
