英语翻译
（1）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.
（2）Let’s take a man we’ll call Mr.Fielder,for example.He did everything connected with farming.He planted seeds,tended the fields,and harvested and sold his crops.At the same time,he did many other jobs on the farm.However,he didn’t make the bricks for his house,cut his trees into boards,make the plows（犁）,or any of other hundreds of things a farm needs.Instead,he got them from people who specialized in doing each of those things.
（3）Suppose there was another man we shall call Mr.Plowright.Using what he knew about farming and working with iron,Mr.Plowright invented a plow that made farming easier.Mr.Plowright did not really like farming himself and wanted to specialize in making really good plows.Perhaps,he thought,other farmers will trade what they grow for one of my plows.

也许有那么一个人,我们称呼他为普罗莱特先生.利用他对于农业和铁所了解的,他制作出了一种犁,可以使耕田更为便捷.普罗莱特先生其实自己并不是很喜欢农业,只是想要更专业于制造很好的犁.也许,他想,其他的农夫会拿他们种出来的东西和我交换我的犁.
