明石 高峰:劝说某人(成功,不成功)

劝说某人成功应说：persuade sb to do sth或persuade sb into doing sth.
劝说不成功应说：try to persuade sb to do sth或try to persuade sb into doing sth.
如：
He persuaded me to stop smoking. 他说服我戒烟了。
I tried to persuade him to buy the book, but he didn't listen to me. 我尽力去说服他买这本书，但他不听我的。

persuade somebody to do something 劝说某人做某事
prevail upon/on somebody to do something 劝说某人改变想法，做原来不愿意做的事情

persuade convince advise

persuade和convince意思均为“说服”；前者着重感情上的“敦促，劝告”，后者着重理智方面的“辩论，证明”，两者结构相同，即：
persuade(convince) sb. that..
persuade(convince) sb. of sth.
eg.He persuaded me that that was not worth buying.
他说服我，那东西不值得买。

persuade还可以表示“说服某人做（或不做）某事”，其结构为：
persuade sb. not to do sth.
persuade sb. into (out of) doing sth.
eg.He persuaded me to do that.(=He persuaded me into doing that.)
他说服了我去做那件事。

persuade和convince都表示结果，即说服了；若表示“说服”或“劝说”的动作，常用try to persuade（或convince），也可用advise来表示。
eg.I advised(或tried to persuade) him to start early but he didn't listen.
我劝他早点动身，可他不听。
