When he was a child, he loved to read and try new experiments. He was always asking questions, and he often did experiments at home to find the answers. Later, he made the first long-lasting light bulb after trying more than a thousand times. His invention changed the way people live at night. From then on, cities became bright and people could work and study after dark. He also built a lab where he worked with young people. Together they invented the record player and improved the telephone and the camera. Edison believed that genius is one percent inspiration and ninety-nine percent hard work. In his eyes, hard work was much more important than talent. He seldom slept for a long time, and he kept working even when he was old. During his life, he had more than one thousand inventions, which made him one of the greatest inventors in history. His story tells us that a small idea can grow into something great. If we keep trying and never give up, our dreams may come true one day, just like Edison’s. 根据短文内容，选择最佳答案。 21. What did Edison love to do as a child? A. Read and try experiments. B. Play sports. C.
