persuade 的核心是行动结果——对方最终真的去做了。与 convince 的区别在于：convince 改变的是"认知"（对方相信某事为真），persuade 改变的是"行动"（对方按你说的去做）。I persuaded him to quit smoking——他戒烟了，这是结果。他心里是否真的认同"吸烟有害"不重要，关键是行动发生了。I persuaded him that smoking was harmful——这里 persuade 后接 that 从句，语义向 convince 靠拢，强调认知改变。两种结构并存，但高考默认的核心搭配是 persuade sb to do sth。
释义
1
v.说服某人做某事（改变行动）
She finally persuaded her father to buy her a bicycle.
她终于说服父亲给她买了一辆自行车。
2
v.劝说某人相信某事（改变认知）
He persuaded us that the project was worth trying.
他说服我们相信这个项目值得尝试。
语感
persuade = 劝到对方动了，不只是信了
说服劝说劝动劝导
persuade 的落脚点是行动：对方最终做了某件事。convince 的落脚点是信念：对方在内心真正相信了某件事。口语中这两个词经常混用，但以下这个对比能帮你在考试中区分：I convinced him that the plan was good（他相信了计划是好的）vs I persuaded him to follow the plan（他照着计划做了）。前者可能行动了，也可能没有；后者一定行动了。高考写作里，persuade sb to do 比 make sb do 或 get sb to do 更正式、更书面。

persuade sb not do 缺少 to，否定不定式结构是 not to do，不是 not do
✓

⚠️persuade vs convince 义项混淆
The coach persuaded the team to train harder.
✗
教练使球队相信应该更努力训练
✓
教练说服了球队，他们最终真的加强了训练（行动发生了）
persuade 强调结果：对方真的去做了
⚠️try to persuade ≠ persuade
✗
I persuaded him for an hour but he still refused.
（语义矛盾）我劝了他一小时但他仍然拒绝了。
persuade 内含"成功说服"的结果，若最终失败，应用 try to persuade 或 attempt to persuade

Q1对错判断
判断下面句子里 persuade 的用法是否正确：
I persuaded him for two hours but he still wouldn't come.
我劝了他两个小时，但他还是不肯来。
✓ 正确版本
I tried to persuade him for two hours, but he still wouldn't come.
我努力劝说了他两个小时，但他还是不肯来。
persuade 包含"成功说服"的结果义，和"still wouldn't come"矛盾。劝了但没成功，用 try to persuade。
