以下是一篇约一分钟的关于勇敢的英语演讲小短文：

Dear friends,

Today, I want to talk about bravery. Bravery is not the absence of fear, but the willingness to face it and act despite it. It's the soldier charging into battle to protect his country. It's the firefighter running into a burning building to save lives. It's the student standing up for what's right even when it's unpopular.

Bravery is in all of us. It's the voice inside that tells us to take that leap, to try something new, to fight for our dreams. Let's be brave in our daily lives, for it is through bravery that we grow, we learn, and we make a difference.

Thank you!
