    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.

    Mobile phones are very popular with people. They are becoming smaller and more convenient.

Now the scientists in Canada made a smartphone (智能手机）from electronic paper. The PaperPhone is flexible. People can control it by bending it or writing on it with a pen.

    Though the PaperPhone is only millimeters (毫米）thick, people can do many things with it. For example, people can use it to make phone calls, read books, watch movies and play music. So many people use it as a computer.

The scientists think there will be no paper in the office. And people can store what they want in the PaperPhone.

The scientists from Queen's University in Kingston，Canada said the PaperPhone would be in style in the future. It may be the end of paper and printers.

To make people be interested in this kind of mobile phones, the scientists will make it more beautiful. People will see the PaperPhone on May 10 this year.

    George Stephenson was born in 1781 in a poor family. He had to start work when he was only eight. When George was fourteen，he became his father's helper. He spent a lot of time learning about engines. On holidays, he often took one engine into pieces and studied each piece carefully. Soon he became a very good worker though he could not read or write.

    He began to learn the English letters when he was seventeen years old. Every day after he did twelve hours of hard work，he walked a long way to have lessons from a young teacher.

    On his eighteenth birthday, he wrote his own name for the first time in his life. George invented many things in his life. The train was the greatest one among them. Today when we watch or take trains from one place to another, we will think of this great man—George Stephenson.

    Many people like to watch TV. Watching TV is one of the most important activities of the day. TV brings the outside closer to people's homes. Some people say the world is smaller than before because of TV.

    What's going on in the other countries? How do people live in places far away? Is there a good sports game somewhere? What's the life like in the deepest parts of the sea?

    If you want to answer these and many other questions, just turn on the TV and watch it. You can see a lot and learn a lot. Of course, people can also learn through reading or listening to the radio. With TV, however, they can learn better and more easily. Why? Because they can hear and watch.

    TV helps us a lot. TV often gives us new ideas. We learn newer and better ways of doing things.
