急! 15點! 有沒有人知道”默哀三分鐘,下半旗致哀”既英文是甚麼?

to pay a three-minute silent tribute with the flag at half mast

英文報紙上寫的,應該不可能有錯
原句是
Chinese President Hu Jintao paid a three-minute silent tribute to victims of the May 12 earthquake with the flag at half mast.

希望幫到你啦!

Observes three mintes silence, flags were to fly at half-staff

mintes should be minutes

Observes three minutes silence, flags were to fly at half-staff

to observe silence to express mourning
