Thomas Alva Edison is one of the greatest inventors of all times. One of
his most famous achievements is the electric light. He tried thousands of times
to make a long-lasting light bulb (灯泡) Although the light bulb is not his invention, he is the only one
to have made such a successful light bulb. Many people remember him for the
invention of the electric light. He held a lot of patents (专利权) worldwide. Many of them were approved (批准)
in the USA.
We can find his inventions in many fields. In fact, many of the advanced
inventions were based on his ideas. He invented a phonograph (留声机), a film picture
camera, a ticket recorder and so on.
Edison was not a good student at school. But he loved to do new
experiments. When he was still a child, he built his first lab to perform his
experiments.
An amazing story of Edison's childhood is that he almost made his
servant die. Edison used to think that birds ate insects and these insects
might make them fly. So he collected these insects and blended them to make
juice. He then let his servant drink the juice. After drinking the juice, the
girl lost her sense. But luckily, she was saved.
