Thomas Edison was born in America. He invented plenty of electric appliances(电器) and people from all over the world know him. At that time, there was no electric lamp in the world. And it brought people much trouble. Young Edison decided to invent it. He didn’t know which material was suited to be a lamp filament(灯丝). He failed and failed and he spent a lot of time on it. Some of his friends asked him to stop the experiments, but he didn’t listen to them and tried his best to find the material.
One afternoon, one of his friends came to visit him, he was doing his experiments in the lab when the man came in. But he only asked his friend to sit down and didn’t stop to talk with him. The man sat for a long time and Edison said nothing to him. His friend was angry with him and said, “You’ve done the experiments 1,200 times but you failed 1,200 times too!”
“You’re right, my friend,” Edison went on doing his experiments and said. “But I’ve known 1,200 materials are not suited to be a lamp filament!”
