英语翻译
Protagoras was among the great teachers of ancient Athens.He taught many subjects,including the laws of argument（辩论）and the right use of language.It is said that he was the first teacher to accept money for his services.
A student,Evalthus,heard of this famous teacher and asked him to give him lessons.However,Evalthus didn’t want to pay for his lessons at once,and after some discussion it was finally agreed between them that Evalthus should pay only if he won his first case in the court.For if he won,it would prove that he had been taught well.
The lessons began and Evalthus proved himself to be a good student.But he refused to pay Protagoras anything at the end of his studies.
Protagoras therefore took Evalthus to the court and told the judges that he wanted his money.He explained that he must be paid whether he won or lost the case.“Whatever you decide,” he declared（宣称）to the judges,“I must be paid.For if you decide in my favor（赞成）,then I win the case,and so I must be paid.But if you decide against me,the Evalthus has won him first case in the court; according to our agreement,he must pay me for his lessons.Therefore I shall get my money whatever happens.”
The Athenian judges found no fault in it,so they asked Evalthus to reply.
“No,it’s quite clear,” said Evalthus,“that I need not pay.If the judges decide in my favor,then I have won the case,and I need not pay.But if Protagoras wins,then I have lost my first case.Therefore,according to our agreement,I do not have to pay.So I need not pay in any event.”

普罗塔哥拉是古代雅典的伟大的教师.他教许多学科,包括争论的法律（辩论）和语言的正确使用.据说他是接受钱为他服务的第一位老师.
一个学生,evalthus,听到这个著名的老师要求他给他教训.然而,evalthus不愿意付一次功课,和一些讨论,最终同意了他们之间的evalthus应该只有他在法庭上赢得他的第一个案件后.如果他赢了,就证明他已经教得好.
课程开始和evalthus证明自己是一个好学生.但他拒绝在学业完成支付普罗泰戈拉什么.
普罗塔哥拉因此把evalthus向法院告诉法官,他想要他的钱.他必须支付他是否赢得或输掉案件.“无论你做什么决定,”他宣称（宣称）法官,“我必须支付.如果你决定在我的支持（赞成）,然后我赢了官司,所以我必须支付.但是如果你对我的决定,evalthus赢得了他在法庭上第一例；根据我们的协议,他必须为他的课给我.因此,我将得到我的钱,不管发生什么.”
雅典法官没有发现故障,所以他们问evalthus回复.
“不,很显然,说：”evalthus,“我不需要支付.如果我喜欢的决定的法官,然后我赢了的话,我不需要支付.但如果普罗胜,我失去了我的第一次.因此,根据我们的协议,我不必支付.所以我不需要支付任何事件.”
