Dave is my friend. His family is rich. His parents always give him lots of pocket money. But Dave thinks his parents work very hard and it's not easy for them, so he always tries his best to save money. He has some good ways to do it.

    Dave likes reading. He has lots of books. He tells me he often buys books online, because they're cheaper. And when he has free time, he often goes to bookstores or libraries to do some reading.

    Dave has a bike. He usually goes to school by bike instead of taking a bus. Sometimes when it rains or snows, he walks. These two ways help Dave keep healthy and save some money.

    Dave brings a bottle of water to school every day. When other students drink juice, he enjoys his water. He thinks water is the cheapest but the best drink.

    Some students think Dave is mean. But I don't think so. I think he is right. What do you think of him?

    One day when Jack was walking in the park, he saw a woman, who lived a few miles away, sitting on a bench(长凳) with a dog beside her. The dog was looking up at the woman.

    Jack walked up to the woman and said, "Hello, Sue, how are you? May I sit and talk with you for a while?" "Of course, please sit down," Sue said. Jack sat down next to Sue on the bench, and they talked quietly together. The dog continued to look up at Sue, as if waiting to be fed.

    "That's a nice dog, isn't he?" Jack said, pointing(指着) at the animal.

    "Yes, he is. He's handsome. He's a bit of a mixture(杂交品种), but that's not a bad thing. He's strong and healthy."

    "And hungry," Jack said. "He hasn't taken his eyes off you. He thinks you've got some food for him."

    "That's true," Sue said. "But I haven't."

    They both laughed and then Jack said, "Does your dog bite?"

    "No," Sue said, "He's never bitten anyone. He's always gentle and friendly."

    Hearing this, Jack decided to hold out his hand and touched the animal's head. Suddenly it jumped up and bit him.

    "Hey!" Jack shouted. "You said your dog didn't bite."

    Sue answered in surprise, "Yeah, I did. But this is not my dog. Mine's at home."

    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!
