The person I admire most is Edison. He is one of the greatest scientists in the twentieth century. He is

famous around the world as an inventor as well. In 1879, he succeeded in inventing the lamp after thousands

of times of tests. Edison devoted all his life to his research. During his life, he had over one thousand inventions

and made a great contribution to the development of mankind. I consider him as my hero. From him, I have

learned that whatever difficulty I meet, I should never give up.
