一小段英语短文翻译1------------务必高手帮忙
No one knows for sure when advertising first started. It is possible that it grew out of the discovery that some people did certain kinds of work better than others did them. That led to the concept of specialization, which means that people would specialize, or focus, on doing one specific job.
请标准翻译（不要机器翻译的）,谢谢

这导致了专业化的概念,也就意味着人们可以专业分工或专注地做某一种工作.
