persuade

1.persuade现在作“说服”解，假使说了而未能说服便不可用persuade。如He has persuaded her to go是“他已经说服她去而她真的去了”。又如I shall persuade him to go是“我将说服他去而使他真的去”，没有“姑妄劝之”的意思。I shall try to persuade him to go或I shall advise him to go才有这个意思。I never persuade him to do it是“我说服他做这件事总是不成功”，不是“我决不说服他做这件事”，也不是“我总是说服他不做这件事”。

persuade用作“使（人）相信”解也指成功的，如I shall persuade him that he is mistaken是“我将使他相信他确实是错的”。

但He is persuading her to go是“他正在说服她去”，不一定成功。

2.下面两句意思相同，第二句语气重些，但不及第一句普通：

• I have persuaded him to do it.
• I have persuaded him into doing it.
