Ⅴ. 阅读理解 On a summer day in 1941, a Swiss man named George de Mestral took his dog for a walk in the mountains. When they came home, George discovered that both he and his dog were covered with burrs (带芒刺的小果实). As an engineer, George naturally began to wonder how the burrs stuck to his dog and his clothes. Then he looked at them carefully. He found that the burrs had little hooks (钩子), which allowed them to stick to things like clothes. George realised that he could use this finding to create a new way to fasten (扣紧) things. It was a very long journey from the first idea to the final product. It was easy to find materials that could stick together, but finding materials that would continue to do so after years of use was difficult. George tested a very large number of different materials and production methods. After years of research and work, he invented what is known today as Velcro (威扣魔术贴). In 1958, George started Velcro Industries to turn his idea into a product. A few years later, the product became popular around the world. Today Velcro is used everywhere. It’s used in backpacks, jackets, wallets, children’s toys, etc. It even turns up in places you wouldn’t expect. For example, Velcro has been used by NASA for astronauts’ spacesuits. The product was also used to hold the equipment together during the very first artificial heart transplant (人工心脏移植). ( )31. Where did George get the idea of inventing Velcro? A.
