对某人承诺英文

给Marry的承诺1,promise Mary sth.2,还可以用 give Mary my word 承诺某人某事 可以翻译成：1，Promise sb. to do sth.2, give A's word to B to do sth 例如：I promise you I will be back before 5pm.I give you my word I will be back before 5pm.

应该是后者吧！比如说：IpromiseU.等等所以应该是PromiseMarry

promise to do sth.; promise to undertake; undertake to do sth.; acceptance of offer; acceptance

promise sb of sth

promise Marry,因为promise是及物动词，不用加介词。
