on behalf of president xu who could not attend today, i would like to first express our cordial gratitude to you for inviting us to this wonderful wedding reception. also, i would like to extend our warmest congratulations to the newly weds, mr. and mrs. brown.
i happen to know the groom, mr. john brown quite well, through our business dealings between his company and mine. i believe mr. brown is by far the most competent and efficient businessman i have ever met. obviously, his competence and efficiency even outside of his profession have also been proved, from the fact that he has today married such a beautiful and intelligent bride. mr. brown, with your youth and talent, i am sure that you will have a very happy married life.
let me say congratulations again to you both, and i hope you will not work too hard and leave your wife alone too often.
congratulations!
由于是正式的场合，所以选择稍显夸张的用词，比较能够为整个演说增添一丝情趣。不妨加入一些衬托新人优点与魅力的插曲。然而切忌趁机“华众取宠”，过于隐私性的`插曲只会使人扫兴。
