At present, air pollution may be the greatest problem and people all over the world pay attention to it. The Chinese government has done a lot to deal with it. One of them is to produce electric vehicles（机动车）,especially electric cars. China plans to put at least half a million electric cars on the road by 2015.

  Electric cars are hard to sell. Even with the help of the government, there are still many problems. So it isn’t easy to get more people to use electric cars. One reason is that the electric car is very expensive. A Shenzhen driver said that an electric car cost 80 percent more than the Santana(桑塔纳). Another reason is that we haven’t built enough charging stations(充电站). Sometimes when an electric car uses up its electricity, it can not work at all. Finally, when ther is something wrong with electric cars, drivers can not find shops to repair them easily.

  Besides China, the United States, Japan and Germany also do their best to create electric vehicles. But China has done more than them.
