・strong in the face of adversity
・weak in the face of adversity

「在正式場合表現強大」可以用strong in the face of adversity/deal with the challenges 來表達。
in the face of adversity 表示"在逆境中不屈服"，
deal with表示"處理、應對"。

I have to give a speech in front of people, and I'm okay with it because I'm strong in the performance.
（我必須在人們面前演講，我沒關係，因為我在正式場合表現強大。）

weak in the face of adversity也可以同樣表達「在正式場合表現軟弱」。
My hands are starting to sweat because I am weak in the face of adversity.
（我手開始出汗，因為我在正式場合表現軟弱。）
