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!

    Mark and his brother Jason both were looking at the shining new computer enviously, Jason was determined not to go against their father's wishes but Mark was more adventurous than his brother. He loved experimenting and his aim was to become a scientist like his father.

    "Dad will be really mad if he finds out you've been playing with his new computer." Jason said. "He told us not to touch it."

    "He won't find out, "Mark said." I'll just have a quick look and shut it down."

    Mark had been scolded before for touching his father's equipment. But his curiosity was difficult to control and this new computer really puzzled him.

    It was a strange—looking machine--one his dad had brought home from the laboratory where he worked. "It's an experimental model, "his father had explained," so don't touch it under any circumstances." But his father's warning only made Mark more curious. Without any further thought, Mark turned on the power switch. The computer burst into life and seconds later, the screen turned into colors, shifting and changing and then two big white words appeared in the centre of the screen: "SPACE TRANSPORTER."

   "Yes!" Mark cried excitedly, "It's a computer game. I knew it! Dad's only been pretending to work. He's really been playing games instead. ''A new message appeared on the screen：

    "ENTER NAMES

    VOYAGER 1…

    VOYAGER 2… "

    Mark's fingers flew across the keyboard as he typed in both of their names.

    "INPUT ACCEPTED START TRANSPORT PROGRAM. AUTO RETRIEVE INITIATED(自动回收程序已启动). "

    The screen turned even brighter and a noise suddenly rose in volume.

    "I think we'd better shut it off, Mark, "Jason yelled, reaching for the power switch. He was really frightened.

    But his hand never reached the switch. A single bean, of dazzling white light burst out of the computer screen, wrapping the boys in its glow(光芒), until the)themselves seemed to be glowing. Then it died down Just as suddenly as it had burst into life. And the boys were no longer there. On the screen, the letters changed.

    "TRANSPORT SUCCESSFUL. DESTINATION：MARS. RETRIEVE DATE：2025."

    There is a 41-year-old woman from California known as Anna, and she remembers almost every day of her life since(自从)she was eleven. There is an 85-year-old man known as Eddy, and he only knows a little.

Eddy is warm and friendly. He laughs a lot. He looks just like any other grandfather in the world. But 15 years ago  he was sick. Then he only knows the people in the room with him. Every morning, he gets up, has breakfast, and then goes back to bed to listen to the radio. Often he forgets that he has done these things. Sometimes he has breakfast three times in the morning.

    For Anna, the past is always there. She remembers the person giving her a call at 12:34 pm on Sunday, August 3, 1986. She remembers that on March 28, 1992, she had lunch with her father at the Beverly Hills Hotel. She remembers the food and every word of the talk. She remembers the weather.

    Anna said, "I remember the good things and that is nice. But I also remember the bad things. Ten years later, I still get angry with myself for doing something wrong. I would love for just five minutes to be a normal (正常的)person and not have all these things in my head."
