五、很多发明创造都是从对细节的观察开始的。阅读鲁班的故事,完成任务。
A long time ago,there was a craftsman(工匠). His name was Lu Ban. One day,Lu Ban needed to work on a mountain. He grabbed(抓住) some weeds(杂草) to climb the mountain. A leaf cut his finger. Lu Ban thought,“How could such a small leaf hurt my finger?” He looked at the leaf carefully. There were many teeth on the leaf,and the teeth were sharp. “Could I make a tool with teeth like these? I could cut things with it easily,” Lu Ban said to himself. Soon Lu Ban made a saw. He used it to cut wood. Of course he could work faster than before. It was the first saw in the world. People are still using this kind of tool today.
