以前在拳擊比賽中，如果一方想挑戰(zhàn)另一方，就把自己的帽子扔進拳擊臺里，這里的ring指“拳擊臺”。現(xiàn)在這個成語的意思是說某人欣然迎戰(zhàn)，接受挑戰(zhàn)。
　　例句：
　　1.I think you’d make a great class president. You should think about throwing your hat into the ring.
　　2.You know they’re looking for volunteers for a mission to Mars. I think I’m going to throw my hat into the ring.
　　注意：
　　另一個短語to throw in the towel也是源于拳擊運動，但是含義完全不一樣。這個短語的意思是因為困難而放棄了。
　　例句：
　　1.I’ve tried to solve this maths problem for days but I’m going to have to throw in the towel. I just can’t figure it out.
　　2.That was a poor performance by the team today. It looks like they just threw in the towel when they went behind.
