Electric cars may seem like a recent invention，but they have been around for years.In the early 1900s，there were more electric cars on the road than gasoline （汽油）cars，because at that time，gasoline was expensive compared with other fuels （燃料），so electric cars were more popular.
    When gasoline prices dropped and new technologies on gasoline cars were developed，electric cars were out of date.Gasoline cars became more popular instead，because they could go farther without stopping.
   During the 20th century，gasoline cars got bigger，heavier and faster.They needed more fuel，and it caused more air pollution.For years，the car makers didn't worry about pollution.They didn't worry about how much gasoline cars used，either.But when people began to realize that there was not enough oil on the earth，they asked car makers to produce more efficient（高效能的）and less polluting cars.
   One way of solving the problem was a "hybrid" car（混合動力車）.They can run partly on gasoline and partly on electricity.Hybrid cars became popular in the 2000s because gasoline prices went up while prices of hybrid cars went down.
    An all electric car uses no gasoline.The problem，however，is that car batteries（電池）need to be recharged（再充電）.That makes electric cars not so suitable for long journeys.Many people are not pleased with it.The government and car makers are working together to develop safe，cheap and useful electric cars. When more and more people have these electric cars in the future，a gasoline station may disappear.
