以前在拳擊比賽中，假如一方想挑戰另一方，就把我們的帽子扔進拳擊臺里，這里的ring 指拳擊臺。目前這個成語的意思是說某人欣然迎戰，同意挑戰。
例句
I think youd make a great class president. You should think about throwing your hat into the ring.
You know theyre looking for volunteers for a mission1 to Mars2. I think Im going to throw my hat into the ring.
請注意
另一個短語 to throw in the towel 也是來自于拳擊運動，但含義完全不同。這個短語的意思是由于困難而舍棄了。
例句
