Cars make our lives more convenient. But theycan also be a problem. For example, fossil fuel (化石燃料)cars mainly cause air pollution.

    To improve the environment, many countriesare developing electric vehicles (EVs,电动车).Among them, China is taking a leading role and has created the world's largestEV market.

    Last year, over 40 per cent of the 753,000EVs sold in the world were sold in China, more than twice as many as the numbersold in the United States.

    "Filling up a fossil fuel car with gas(汽油) is more expensive than charging (充电) an electric car," said Wu Hao, who bought an electric carthis year.

    However, there are still some problems. Itcan be hard to find charging piles (充电桩) andthe cars can't go far before being recharged.

    Some of these problems are being solved. In2014, China had 31,000 charging piles. Now China has the world's largest EVcharging network, with more than 450,000 charging piles in total.

    Developing EVs is one of many efforts thatChina has made to cut down pressure on its environment after the governmentpromised to stop increases in carbon dioxide emissions (二氧化碳排放量) by 2030.

    "As China goes, so will the world'scar industry," the Wall Street Journal said.
