SECTION B (10 points) Direction: Read the following passage and answer the questions according to the information you get in the passage and the required words limit. Several years ago, Masaru Ibuka, the chairman of Sony, was at a company planning a meeting. Suddenly he had a brilliant idea. He stopped the meeting and asked everyone present what would happen if Sony removed the recording function and speaker and sold headphones(耳机) with a tape player instead. Almost everyone thought he was crazy. Still, Ibuka kept thinking about his idea and worked at refining it. The result, of course, turned out to be the wildly successful Sony Walkman. Good ideas often start with a really silly question. Bill Bowerman was making breakfast one day. As he stood there making waffles(蛋奶烙饼)for his son, he wondered what would happen if he poured rub ber into his waffle iron(蛋奶烙饼烤模).So, he tried and the result looked something like the bottom of most sports shoes we see today. Still, when he took this idea to several existing shoe companies he was literally(确实地)laughed at. In fact, every single company turned him down. Though rather disappointed, Bowerman was determined and went on to form his own company, making NIKE athletic shoes. Sometimes good ideas grow out of frustration(挫败). When Fred Smith was a student at Yale University, he had some paperwork that he needed to have delivered a cross the country the next day. Smith was amazed to find out that overnight delivery(隔夜送货) was impossible. He sat for a long while wondering why. Why couldn’t there be reliable overnight mail delivery service? He decided to design one. Smith did just that and turned his design into a class project. His business professor thought it was not a good class project and gave him only a C. However, Smith refined the idea in that class project and eventually turned it into one of the first and most successful overnight mail services in the world——FedEx. 81.
