When Louis Braille was a very small boy, one day, while played, he picked up a small tool of a sharp point, Louis fell, the point entered into his eye, and later he became blind. He wanted such much to read books for the blind that at last he invented a way for the blind read and write. People didn’t believe him first. One day a blind girl was playing piano. People thanked her of playing so well. She said it was Louis Braille who made that possible for her to learn music.
Key：
1.正确。
2.将played改为playing。while playing相当于while he was playing。
3.将Of改为with。with相当于having。
4.去掉into。enter为及物动词。
5.将such改为so。so接形容词或副词，后文that是个信息词，可判断是so…that…句式。
6.在read之前加to。为forsb.to do…句式。
7.在first之前加at。at first起初。
8.在plano前加the。通常在表示乐器的词前加定冠词。
9.把of改为for。thank sb. for为某事感谢某人。
10.将that改为it。此处it做形式宾语。
