Good ideas often start with a really silly question. One day, when Bill Bowerman was making waffles（华夫饼）,he 26 what would happen if he poured rubber into his waffle iron. Later, he tried it and the 27 looked something like the bottom of most sports shoes we see today. When he took this 28 to several shoe companies, he was 29 . In fact, every single company 30 his idea. Though rather discouraged, Bowerman went on to 31 his own company, making x x sports shoes.
Sometimes good ideas grow out of frustration（沮丧）.When Fred Smith was a student at Yale University, he needed to have some paperwork 32 across the country the next day.But Smith found out that overnight delivery was 33 . He wondered why there could not be such kind of 34 to have mails delivered within a short time. He decided to design one. Smith did so and turned his design into a class project. His business professor gave him only a C for his efforts. 35,Smith did not lose heart. He improved the design and 36 turned it into one of the first and most successful overnight mail services in the world—x x.
We know today that each of these ideas led to a 37 product or service that has changed the way we live. The best questions are usually open-ended and are often 38. Children are not afraid to ask such questions, but 39 often are. Think how 40 the world might be if people never asked “silly” questions!
