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(jìn)拳擊臺(tái)里，這里的ring指“拳擊臺(tái)”�，F(xiàn)在這個(gè)成語(yǔ)的意思是說(shuō)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(gè)短語(yǔ)to throw in the towel也是源于拳擊運(yùn)動(dòng)，但是含義完全不一樣。這個(gè)短語(yǔ)的意思是因?yàn)槔щy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.
