Usually, students are not encouraged to run or jump around in the hallways. However, students in a British grammar school really enjoy {#blank#}1{#/blank#}（run） on the tiles（瓷砖） of the hallways and their teachers even encourage them to do that.

    Why? It is because the hallways were {#blank#}2{#/blank#}（build） with special tiles. When students jump on the tiles, electricity will be generated（产生）. After one year, the electricity {#blank#}3{#/blank#}is generated from the tiles can be enough for 853 mobile phones to get full power again, or for an electric car to drive seven {#blank#}4{#/blank#}（mile）. It's amazing, isn't it?

    The tiles are really {#blank#}5{#/blank#}fascinating invention. Students can not only play in the hallways, but {#blank#}6{#/blank#}help power the lights in their school hallways and other devices（设备） in their classrooms. Besides, this is a good way to teach students to be {#blank#}7{#/blank#}（create）. They will be inspired to be scientists, inventors and engineers {#blank#}8{#/blank#}the future to find clean energy for all humans.

    The inventor of the magic tiles is Laurence Kemball-Cook. He was once a student in this school. Now, he is the CEO of {#blank#}9{#/blank#}（he） own company. The hallway tiles are not Laurence's only invention. He has also invented a special dance floor, which can be {#blank#}10{#/blank#}（easy） used at music festivals. It allows dancers to charge their mobile phones while they are dancing on the dance floor.

    Mr. White {#blank#}1{#/blank#} (work) in an office. One day, while he{#blank#}2{#/blank#} (have) lunch, a friend visited him. They were very glad and talked a lot. Then they looked at the clock on the wall. It was time {#blank#}3{#/blank#} (go) to the office. He had to say goodbye to his friend and {#blank#}4{#/blank#} (leave). It {#blank#}5{#/blank#} (rain) heavily and the streets were wet. He drove too fast {#blank#}6{#/blank#} (see) the red light. He could not stop his car and hit a car in front of his. An old man got out and shouted angrily," What are you doing? Do you want to hit me to death?" "I'm sorry, sir," said Mr. White. "I didn't find the lights turning." Then he {#blank#}7{#/blank#} (bring) out a bottle of wine and gave it to the old man. "It's very cold today, sir," said Mr. White. "Please drink a little, and then you'll be warmer. "The old man drank some wine and became happy. "I {#blank#}8{#/blank#} (feel) much better now. Why not {#blank#}9{#/blank#} (drink) some?" he asked. "I can't drink anything now, sir," answered Mr. White. "I'm {#blank#}10{#/blank#} (wait) for the policeman to come. Only drunkards (酒鬼) cause accidents, you know." What do you think of Mr. White? Is he responsible?
