Doctor Seuss was born in 1904. He was one of the most successful 1 book writers in the world. His books are very popular2 young readers. They enjoy the invented words and the pictures of funny animals and plants. In 1954, Life magazine published(刊登) a report 3 school children. The report said many children's books were boring. Doctor Seuss 4hoped to help children. So he 5 to write books that were interesting and 6 to read. He used words with the same ending sound, like "7" and "wish". He did not receive training in art. However, he 8 the pictures for most of his books. He died at the age of 87, but his influence(影响) remains. 9 his books have been sold worldwide. People say his books helped change the way American children learned to read. Yet, his books are loved by people of all 10. Doctor Seuss once said, "I do not write for children. I write for people."

    Once, Einstein gave a lecture in a university. After his speech, the audience started asking questions.

    A girl asked, "Do you think you're a giant of science？" Einstein said with a smile, "A giant is a person who is tall in height. You see I'm so small, how can I be a giant? Maybe I see a bit farther, only because I stand higher！"

    Then a boy asked, "You mentioned you stand higher than the others. It reminds me that you had a talk with a lady on the top of the Alps (阿尔卑斯山).I don't want to ask what you talked, but I want to know whether you realised you have been a top in the history of science when you stood on the top."

    Looking at the boy carefully, Einstein replied, "Well, my height cannot become a top. And there is no top that no one can get to, so we don't want to be a top, but we want to be a person to climb the top！"

    Then he took up a piece of chalk and wrote on the blackboard, "Standing on the top, you are not tall, but even smaller！"

    Then he said, "Though I stand tall, in the eyes of the world I'm still small! Finally, I can tell you a sentence, which was the last one I told the lady on the top of the Alps, 'Any top can be reached, for there is no giant in the world but the one who stands higher！'A storm of applause(掌声) sounded. The lady who listened to Einstein's instruction on the Alps that year was no other than Madam Curie!

    Tim Berners­Lee is not the most famous inventor in the world. However, his invention has changed our lives. He was born in London, England in 1955.When he was a small boy, Tim was interested in playing with electrical things. He studied science at Oxford University. He made his first computer from an old television at the age of 21.Tim started working on early computers. At that time, they were much bigger than now. He worked in England then Switzerland. Tim was really interested in two things, computers and how the brain works. How could the brain connect so many facts so quickly? He had to work with people all over the world. They shared information about computers. It was hard to manage all the information. He answered the same questions again and again. It took a lot of time. It was even difficult for computers in the same office in Switzerland to share information. Tim also forgot things easily. Could a computer work like a brain? Could it “talk” to other computers?

    There was an Internet already but it was difficult to use. In 1989, Tim Berners­Lee invented the World Wide Web (WWW) all by himself. This had a special language that helped computers talk to each other on the Internet. When people wanted to share information with others, they used the World Wide Web. The Internet grew quickly after that.

    Tim Berners­Lee doesn't think he did anything special. He says that all of the ideas about the Internet were already there. All he did was to put them together. He says that many other people worked together to make the Internet what it is today. Most inventors want to become rich. But Tim gave away the World Wide Web for nothing. He now works in America. He helps people share technology and wants the Internet to be free for everyone to use. Maybe he is the most important but least famous inventor in the world today!
