Do you know who I admire? Neither father nor mother, but the great inventor-Edison. Edison invented many things related to our lives, such as movies, telephones, electric lights, televisions, phonographs and so on, which made great contributions to human civilization and progress. Do you know how he invented so many things? When he was a child, he only attended primary school for three months, but he always asked "why" when he encountered problems. If Edison can't do the experiment well, he won't lose heart and keep working hard. This is the reason for his success. Finally, please remember Edison's famous saying: "Genius is 99% sweat plus 1% inspiration." We should learn from Edison's diligent, studious and persistent spirit and study hard.
