Wnen Thomas Edison was 15,a train accident injured his ears.Once when he tried to jump on a moving train ,a conductoor grabbed his ears to pull him up.His deafness could have been cured by an operation.ButEdison did not take the opertion.He said being deaf helped him concentrate. 这是关于爱迪生的,应该对学生而言,作为偶像比较好一点.
