Electric cars are dirty. In fact, not only are they dirty, they might even be dirtier than the gasoline-powered cars.
We get electricity mainly by burning something. Those "zero-emissions" cars are likely coal-burning cars. Because the coal is burned somewhere else, it looks clean. It is not true. It’s as if the California Greens are covering their eyes—"If I can’t see it, it’s not happening. " Gasoline is an incredibly efficient way to power a vehicle: a gallon of gas has a lot of energy in it. But when you take that gas(or another fuel) and first use it to make electricity, you waste a nice part of that energy, mostly in the form of wasted heat—at the generator, through the transmission lines, etc.
A gallon of gas may drive your car 25 miles. But the electricity you get from that gallon of gas won’t get you nearly as far—so electric cars burn more fuel than gasoline-powered ones. If our electricity came mostly from wind or geothermal, or solar, then an electric car truly would be clean. But for political, technical, and economic reasons, we don’t use much of those energy sources.
In addition, electric cars’ batteries which are poisonous for a long time will eventually end up in a landfill. And finally, when cars are the polluters, the pollution is spread across all the roads. When it’s a power plant, though, all the junk is in one place. Nature is very good at cleaning up when things are not too concentrated, but it takes a lot longer when all the garbage is in one spot.
It can be inferred from the passage that______.
选项
A、electric cars are not clean in that we get electricity mainly by burning something
B、now electric cars are used more than their gasoline-powered cousins
C、electric cars’ batteries are poisonous for a long time
D、zero-emissions vehicles should be chosen to protect our environment
答案
A
解析
此题为推理题,从文章第二段内容可知电动车是需要通过燃烧煤炭等自然资源来获得电力的,所以电动车并不如人们所认为的那样清洁无污染。可以看出,对应的正是选项A,故选A。
