Many years ago, I saw an interesting movie. It pictured the future life that people could fly in the sky by cars. Of course, I don't think it will happen in the coming time. The change in cars is about the energy. It is said that the cars will use both electricity and gasoline, which can reduce pollution. I think it is a great change for cars. More and more people have cars now and the gas they release brings heavy pollution to the air, which damages our health. The cars can use electricity in the long trip. When it runs out of it, then gasoline can be a substitute. 
许多年前，我看了一部有趣的电影。电影描绘的是未来的生活，那时候的人们可以坐汽车在天空中飞翔。当然，我不认为这样的情况会在未来发生，因为汽车的变化主要在能源方面。据说汽车将使用电油结合，这样就可以减少污染。我认为这对汽车来说是一个巨大的变化。现在越来越多的人拥有汽车，这些车释放的尾气给空气带来了严重的污染，这损害了我们的健康。汽车可以在长途旅行中先用电，电耗尽时，汽油就可以替换使用。
