Most people will think about erasers only when they need to change something on their paper. In fact, erasers have a long history.
The history of the eraser began in the 1700s. There were lots of rubber trees (橡胶树) in South America. People got rubber from the trees and made many things with it. A man from France visiting South America saw this material (材料). He thought it was special and useful. So he sent some to his friends in Europe to study. Some went to a man in England. His name was Edward Nairne.
One day, Edward was writing on his table and needed an eraser. But he didn't use a piece of bread, a popular eraser at that time. Instead, he used a piece of rubber that was on his table. To his surprise, it worked better than bread. That was when Edward had an idea. Soon, he started to make rubber erasers and sell them.
How does the eraser work? When you write on paper, small pieces of graphite stick (粘贴) to paper. Graphite is the black material inside pencils. When you move an eraser on paper, it becomes warm. When it's warm, graphite sticks to it and words come off the paper.
