My grandfather Jack is 96 years old，and he has had an interesting life. He has travelled a lot in his life in the Far East. He visited the Taj Mahal in India and the Pyramids in Egypt. He hunted（狩猎） lions in Africa, and rode a camel in the Sahara Desert. He says the most beautiful place he has travelled to is Kathmandu in Nepal.

    Jack has married twice. His first wife died when she was 32. He met his second wife Maria while he was cycling round France. They have been married for 50 years, and they have lived happily in a small village since they got married.

Jack says that he has never been ill in his life. The secret of good health, according to my grandfather, is exercise. He goes swimming every morning. He has done this since he was a boy. He also has a glass of wine every night! Perhaps that is his secret!

    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."
