Tom's idea was the most interesting. / His invention is called the “Sun Hat Fan”. It is a hat with a small fan on the top. The fan is powered by a solar panel（太阳能板）on the hat, so it needs no batteries. On hot summer days, it blows cool air on your face while you walk. / Tom showed us his design: he first drew a picture, and then made a model with an old hat, a small motor（发动机）and some wire. The model really worked! “The idea came from my grandpa,” Tom said. “He always feels hot in summer, and he doesn't like holding a fan.” / Miss Yang praised him.

We use it every day, but its birth was an accident（意外）. / In 1968, an American scientist, Spencer Silver, was trying to make a very strong glue. Instead, he made a strange glue that stuck lightly and could be used again and again. Nobody knew what to do with it. / Five years later, his workmate Art Fry had a problem. His bookmarks（书签）kept falling out of his book at church. Suddenly he thought of Silver's weak glue. He put some of it on small pieces of paper, and the notes stuck well and came off easily. / In 1980, the Post-it note came onto the market and soon became popular all over the world. / The story of the Post-it note tells us two things: a “failed” experiment may hide a great idea, and it is important to share our ideas with others. 任务一：单项选择 1.What was Spencer Silver trying to make in 1968?

The microwave oven（微波炉）is one of them. In the 1940s, an engineer named Percy Spencer was working near a radar machine（雷达）. Suddenly, the chocolate in his pocket melted（融化）. He was surprised, and then he got an idea. He put corn near the machine, and it turned into popcorn（爆米花）! Later, people invented the microwave oven with this discovery. Now it is one of the most useful machines in our kitchens. So do not be afraid of small accidents—maybe they are the start of a great invention. 学科网（北京）股份有限公司 $
