     People often said Thomas Edison was the greatest of his age. There are only a few men in all of

his history who have changed the lives of other men as much as the inventor of the first useful electric

light. But Edison could never be pleased only because someone said he was a genius(天才)."There

is no such thing as genius," Edison said. He thought what people called genius was mostly hard work.

     But Edison was a dreamer as well as a worker. From his earliest days as a child he wondered

about the secrets of nature. He tried to understand them, and then he tried to learn what he could

usefully do with them.

     Edison enjoyed thinking. He knew that most people would do almost anything instead of thinking,

especially if they don't think very often. But he knew, too, that thinking could give men enjoyment

and pleasure.

     Edison could not understand why someone could not be interested in life. As he loved to think,

he also loved to work. On the day he became 75 years old, someone asked him what idea he had

about life. "Work", he answered, "discovering the secrets of nature and using them to make men

happier," He said he had enough inventions in his mind to give him another 100 years of work.
