・put on a brave face

Even though I was upset, I put on a brave face. (我很沮喪，但我假裝鎮靜。）
直接翻譯為【我擺出勇敢的表情】用於在困難的情況下保持冷靜的舉止。
I pretend to be calm/nomal, evertime I go to the game/match.(比賽時始終保持冷靜。）pretend=假裝/ pretend to be～ = ～假裝是
calm=冷靜的
Keep up appearances, when you are discussing these problems.
(討論這些問題時保持冷靜）
keep up appearances / keep one's head =保持冷靜
