usually, students are not encouraged to run or jump around in the corridor
(走廊). however,students in a british grammar school really enjoy running on the corridor tiles (瓷磚) and their teachers even encourage them to do that.
why? it is because the corridor was built with special kinetic (動能的) tiles. when students jump on the tiles, electricity will be generated ( 產(chǎn)生). after one year, the electricity generated from the tiles can fully charge 853 mobile phones or power(供電) an electric car to drive seven miles. it’s amazing, isn’t it?
the corridor tiles are really a brilliant invention. students ca n not only play on the corridor,but also help power the lights in their school corridors and other devices ( 設(shè)備) in their classrooms. besides, this is a good way to teach students to be creative. they will be inspired to be scientists, inventors and engineers in the future to find clean energy for all humans.
