pledge和promise

Question

如题所述

Answer 1

Pledge(发誓、允诺)：if you pledge to do something
you promise in a serious way to do it! 你发誓要做某事，就表示你严肃地承诺要去做。如：I pledge that by next year we will have the issue solved. 我发誓明年前一定把问题解决。 Promise(承诺)：if you promise you will do something
you are saying that you will definitely do it. 你承诺要做某事，就表示你一定会去做。如：Promise me you will not waste your time. 跟我保证你不会浪费时间。 小结：pledge的程度较强烈(发誓)，且政治人物常用；promise(承诺)的程度较轻，日常生活常用，且Promise常常没有兑现。
