He was once thought to be a boy who was not worth educating. Later, however, he turned out to be a man full of imagination. I admire Edison a lot because of his great contribution to the world. He had more than 1,000 inventions. In his life time, he was always eager to know how things worked, which helped him to have the nickname “the Wizard of Melo Park”. He was also so diligent that he worked day and night. And this explained why he had so many great inventions.第21讲 美文佳句What impresses me most is his famous saying, “Genius is one percent inspiration and ninetynine percent perspiration.” Probably I cannot be an Edison myself, but I can be a hardworking teammate.
