问题补充：
People often said Thomas Edison was the greatest genius(天才) of his age. There are only a few men in all of 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. “There is no such a thing as genius,” Edison said. He thought what people called genius was mostly hard work.
But Edison was a thinker 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 the difficult work of thinking, especially if they do not think very often. But he knew, too, that thinking could give men enjoyment and pleasure.
Edison could not understand why anyone 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.

解析：这篇短文主要介绍了爱迪生。有些人把爱迪生称为天才，但他认为天才是指那些勤奋的人。爱迪生不仅是个发明家，还是个思想家。他喜欢发现自然的奥秘然后用于人类。他喜欢思考，这让他很享受，他认为去发现自然的奥秘并加以使用使他很快乐。
【小题1】细节理解题。根据文中第一段内容He thought what people called genius was mostly hard work.他认为人们所说的天才大多数是努力工作的人。故选B。
【小题2】细节理解题。根据文中第二段内容He tried to understand them, and then he tried to learn what he could usefully do with them.他努力去理解自然的奥秘，然后尽力去学习如何有效使用它们；故此题选C。
【小题3】句意理解题。He said he had enough inventions in his mind to give him another 100 years of work.他说他思想里的发明足够他再工作100年；故选D，对爱迪生来说对为人类工作的时间太短了。
