A few years ago, Masaru lbuka, the head of Sony, was at a company planning meeting. Suddenly he had
an idea. He stopped the meeting and asked everyone what would happen if Sony took away the recording
function and speakers and sold headphones with a tape player instead. Almost everyone thought he was silly.
Still, lbuka kept his idea and worked at it. The result, of course, turned out to be successful Sony Walkman.
    Good ideas often start with a really silly question. Bill Bower man was making breakfast one day. As he
stood there making cakes for his son, he asked himself what would happen if he poured rubber (橡胶) into his
cake iron (蛋糕模具). Later, he tried it and the result looked something like the bottom of most sports shoes
we see today. Still, when he took this idea to several shoes companies, he was laughed at. In fact, every single
company turned him down. Though rather disappointed, Bill went on to form his own company, making NIKE
 sports shoes. 
     We know today, of course, that each of these ideas caused a successful thing that has changed the way
many of us live. The best questions are usually opened (开放的) and are often "Silly", Children aren't afraid
to ask such questions, but adults usually are. Think how difficult the world might be if people never asked
"silly" questions!
