摘　　要：这要看汽车电能的生产方式。电动汽车和汽油汽车,哪种对地球更好呢?问题的答案似乎非常明显:当然,电动汽车一定更环保,因为它们没有排气管,行驶时不排放温室气体。不过,电动汽车并非完美无缺,也存在它们特有的污染问题。尤其要注意的是,电动汽车的电池含有锂等成分,探寻和提纯其原料需要消耗大量能源。It depends on how we make electricity that power these cars.Which is better for Earth:an electric or gas-powered vehicle?The answer to this question might seem blindingly'obvious:Of course electric cars must be better for the environment,because they don't have exhausts'and so don't emit greenhouse gases as they drive.However,electric vehicles(EVs)aren't perfect,and they come with their own set of polluting problems.Notably,their batteries contain components,such as lithium,that require a significant amount of energy to source’and extract.2 But battery production is just one part of an electric car's life span.
