Even Intelligent People Can Fail 小题1:_________ The unusual things about the innovators (创新者) who succeeded in making our modern world is how often they failed. Turn on a light, take a photograph, watch TV, search the web, jet across the Pacific Ocean, talk on a cell-phone. The innovators who left us these things had to find the way to success through a maze (错综复杂) of wrong turns. 小题2:_________ We have just celebrated the 125th anniversary of American innovator Thomas Edison’s success in heating a thin line to white, hot heat for 14 hours in his lab in New Jersey, US. He did that on October 22, 1879, and followed up a month later by keeping a thread of common cardboard alight (点亮着的) in an airless space for 45 hours. Three years later he went on to light up half a square mile of downtown Manhattan, even though only one of the six power plants in his design worked when he turned it on, on September 4, 1882. 小题3:________ “Many of life’s failures,” Edison said, “are because that people did not realize how close they were to success when they gave up.” Before that magical moment in October 1879, Edison had worked out no fewer than 3,000 theories about electric light. But in only two cases did his experiments work. 小题4:________ No one likes failure, but the smart innovators learn from it. Mark Gumz, the head of a camera maker, attributes some of the company’s successes in technology to understanding failure. His popular phrase is：“You only fail when you quit.” 小题5:_________ Over two centuries, the most common quality of the innovators has been persistence (坚忍不拔). That is another way of saying they had the emotional ability to keep on with what they were doing. Walt Disney, the founder of Disneyland, was so penniless after a series of financial failures that he was left shoeless in his office because he could not afford the $1.50 to get his shoes from the repair shop. Pioneering car maker Henry Ford failed with one company and was forced out of another before he developed the Model T Car. |
