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!

    One day, a woman traveled alone in the mountains．When she was walking, she found a precious (珍贵的) stone．She was very happy and put the stone into her bag.

    The next day, the woman met another traveler．The traveler was hungry and the woman opened her bag to s hare her food with him．The hungry traveler saw the precious stone and said, “How beautiful the stone is! Can I have a look?” The woman gave it to the traveler．The traveler looked and looked, and then he asked the woman whether she would like to give it to him．She gave the stone to him without hesitation (犹豫).

    The traveler left．He was very happy because he knew he could get lots of money by selling the stone and he could live a rich life．But a few days later he came back to return the stone to the woman.

    “I know how precious the stone is,” the traveler said． “But I gave it back．I hope that you can give me something even more precious.” “Even more precious? What is that?” the woman asked． “Your beautiful mind is more precious than the stone,” the man said.

    I was 12 when I came to Maywood School three years ago. Like most schools in the US, classes here began at 8:00 am. However, the head teacher, Mr Bergman, found there was a problem — so many students were either missing (错过) the first class or arriving late. My classmates and I often found it hard to keep our eyes open in the mornings, so lessons were no fun for us. Our marks weren't good either.

    In the end, Mr Bergman asked the school doctor for advice. The doctor said that because children's bodies are growing so quickly, they need more sleep than adults (成人). But their body clocks make it hard for them to go to bed before 11:00 pm, so the best time for them to get up is around 8:00 am.

    Mr Bergman decided to do an experiment (实验). He changed the start time for classes to 9:00 am. The school still opened at 8:00 am and teachers used the extra (额外的) hour to prepare lessons.

    I didn't think the new timetable (时间表) would make much difference, but I was wrong. I felt much better! Everyone's grades improved. Also, more students had time for a hot breakfast together in the dining hall. We all felt healthier and happier.

    After three months, Mr Bergman asked teachers, students and parents if they wanted to keep the new timetable. Everyone did.

    One day, I was cooking with my friend Sandy in the kitchen. Suddenly, Sandy cut her finger. I went to her quickly. But to my surprise, I saw computer chips in her finger.

    "Now you know my secret, you have to die!" Sandy said and picked up the knife. "No, please, Sandy. Aren't we good friends?" I shouted. But before Sandy could say anything, she fainted.

    "Oh, Sandy!" I took her to hospital in a hurry. After a doctor checked her, he said, "I'm afraid we can't help her. Why don't you take her to a robot centre?"

    I hurried to a robot centre. A few days later, Sandy was well. She asked, "Mary, why did you save me even after I tried to kill you? "

    "Because I'm sure you are my friend. Can you tell me where you are from?" "I'm from another planet. It's far from here. Thank you, my friend Now I see how friendly people are on the earth." Two days later, a UFO came and picked her up. Since then I've never seen her.
