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.

阅读《三国演义》中的片段，完成下面问题。
孔明传令，教“将旌旗尽皆隐匿；诸军各守城铺，如有妄行出入，及高言大语者，斩之！大开四门，每一门用二十军士，扮作百姓，洒扫街道。如魏兵到时，不可擅动，吾自有计”。孔明乃披鹤氅，戴纶巾，引二小童携琴一张，于城上敌楼前，凭栏而坐，焚香操琴。
却说司马懿前军哨到城下，见了如此模样，皆不敢进，急报与司马懿。懿笑而不信，遂止住三军，自飞马远远望之。果见孔明坐于城楼之上，笑容可掬，焚香操琴。左有一童子，手捧宝剑；右有一童子，手执麈尾。城门内外，有二十馀百姓，低头洒扫，傍若无人。懿看毕大疑，便到中军，教后军作前军，前军作后军，望北山路而退。次子司马昭曰：“莫非诸葛亮无军，故作此态？父亲何故便退兵？”懿曰：“亮平生谨慎，不曾弄险。今大开城门，必有埋伏。我兵若进，中其计也。汝辈岂知？宜速退。”于是两路兵尽皆退去。孔明见魏军远去，抚掌而笑。众官无不骇然，乃问孔明曰：“司马懿乃魏之名将，今统十五万精兵到此，见了丞相，便速退去，何也？”孔明曰：“此人料吾生平谨慎，必不弄险；见如此模样，疑有伏兵，所以退去。吾非行险，盖因不得已而用之。此人必引军投山北小路去也。吾已令兴、苞二人在彼等候。”众皆惊服曰：“丞相之机，神鬼莫测。若某等之见，必弃城而走矣。”孔明曰：“吾兵止有二千五百，若弃城而走，必不能远遁。得不为司马懿所擒乎？”后人有诗赞曰：
瑶琴三尺胜雄师，诸葛西城退敌时。
十五万人回马处，土人指点到今疑。
言讫，拍手大笑，曰：“吾若为司马懿，必不便退也。”遂下令，教西城百姓，随军入汉中：司马懿必将复来。于是孔明离西城望汉中而走。天水、安定、南安三郡官吏军民，陆续而来。
