According to a traditional rule,onepersuades someone to act but convinces someone of the truth of a statement or proposition:
根据一条习惯规则，一个人persuades （说服）某人做某事而 convinces（使确信） 某人相信一句话或一个提议的正确性：
例句：
By convincing me that no good could come of staying, he persuaded me to leave.
通过让我确信留下来没有好处，而说服我离开了。

If the distinction is accepted, thenconvince should not be used with an infinitive:
如果这一区别被接受的话，那么convince 就不应和不定式连用：
例句：
He persuaded (not convinced ) me to go.
他说服（不能用 convinced ) 我离开。

In an earlier survey, a majority of the Usage Panel held that this distinction should be maintained,but the use ofconvince with an infinitive has become increasingly common even among reputable writers, and it is unlikely that this stricture can be maintained for much longer.
在更早的一次调查中，用法专题使用小组成员的大多数人认为这一区别应当保持，但是甚至在知名作家中convince 和不定式连用的用法也已变得日渐普遍起来， 这一限制不可能会保持很久
