4．A famous violinist enters the stage（舞臺(tái)） to perform a solo at a New York City music hall．Getting on the stage is no small task for him．A brain disease he got as a child makes him walk with crutches（雙拐）．
Seeing him walk across the stage is hard to forget．He walks painfully，but confidently，until he reaches his chair．He sits down slowly，puts his crutches on the floor and places his legs in the correct place．Then he picks up the violin，puts it under his chin（下巴），nods to the conductor（導(dǎo)演）and starts to play．
But suddenly something goes wrong．The violinist finishes the first few parts of the piece，but one of the strings on his violin breaks．Everyone hears it clearly．
People think the violinist will need to stop to find another string or violin．But he doesn't．Instead，he stops for a moment，closes his eyes and goes on．He plays from where he left off，with a feeling and power that people had never heard before．
It is impossible to play how he does with only three strings．But this musician refuses to give up．He seems to play the strings in new ways to make the sounds he needed from the missing string．
When he finishes，everyone in hall claps their hands repeatedly for long．
The musician smiles and says，"Sometimes it is up to the musician to find out how much music he can make with what he has left．"
