但是你知道什么诺言你将不得不做什么呢？

But do you know what promise you will have to make?

无论男的在婚前作过什么诺言也好，（ 结婚） 证书就等于是一纸全额收据。

Whatever promise a man may make before marriage, the license is as a receipt in full.

一旦你给了别人承诺，无论发生什么事，你都得实现它，这个就叫‘守诺言’。

Once you give somebody a promise, you must carry it out on matter what will happen. This is called 'keeping one's words.'
