Born in America, Thomas Edison was a great scientist and inventor. He was once thought to be a boy who was not worth educating. In fact, he was a man full of imagination.
I admire Edison a lot because of his great contribution to the world. He had more than 1,000 inventions. In his lifetime, he was always eager to know how things worked, which helped him to earn the nickname the Wizard of Melo Park .He was also so diligent that he worked day and night. And this explained why he had so many great inventions.
What impresses me most is his famous saying, Genius is one percent inspiration and ninety-nine percent perspiration. Probably I cannot be an Edison myself, but I can be a hard-working learner. From him, I realize the secret to success is not when or where you were born, but what you are doing and how you do it in your life.
There is a story that an old woman always feels unhappy, because when the sun comes out, she worries about her daughter's business, because the girl sells umbrella. But when it rains, she stills feels unhappy for she worries about her another daugther's business. People tell her to change his point of view, when the it is fine, she can feel happy about her second daughter's business and when it rains, she can be happy about her first daughter's business. In that way, she will be a positive woman every day. We can't change the fact, but we can treat things in another way, so that we can be positive all the time.
There are many arguments about the advantages and disadvantages of examinations. Some people think that examinations can help them review the lessons regularly, while others maintain that too many examinations have frustrated them.
To me, I think an examination is a good thing for both teachers and students. Teachers can find out how much the students have grasped and then improve their teaching; students, on the other hand, will learn what their weak points are and then study even harder.
