Tim Berners-Lee 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．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 Berners﹣Lee 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 Berners﹣Lee 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!

    Mr. Green made a robot. He could say only one sentence—“There is no doubt (疑问) about it.” The robot always repeated the same words when you spoke to him.

    One day, Mr. Green needed lots of money and he took the robot to the market to sell him. “Who will buy my robot? He is very smart,” he shouted, “Twenty thousand dollars for my robot!”

    A man was surprised that he was asking for so much money. Instead of asking Mr. Green why he wanted so much money, he decided to speak to the robot. “Are you worth (值) twenty thousand dollars?” he asked the robot. “There is no double about it,” answered the robot.

    The man liked the robot's answer so much that he bought him and carried him home. But very soon he found that the robot could say nothing else. He was sorry he bought the robot. He stood in front of the robot and said, “How foolish I was to throw so much money away！”

    “There is no doubt about it,” said the robot.

    My name is Alex. I had an interesting and scary experience last Saturday. At about three o'clock in the afternoon, I was walking down the Main Street. I stopped in front of a jewelry store to look at some rings in the window. I really liked one of the rings. While I was standing there, two men came out of the store. They ran across the street, got into a car, and drove away quickly. Then I saw something on the ground. It was a black bag. I thought maybe they dropped the bag while they were driving away in the car.

    I went to pick up the bag and opened it. There was a diamond watch in the bag. I took the bag with the watch into the jewelry store and showed it to the store manager. The manager looked scared by what had happened but he was very happy to see the watch. He said the two men were thieves, and that the police were looking for them. He also said the watch was very expensive. To thank me, he gave me fifty dollars. I was happy that I helped him. However, the thieves stole many pieces of jewelry. They took ten rings, three watches, four necklaces, and ten pairs of earrings. I hoped the police would catch them soon.
