正确原文：

Ourelectric car is the way of the future. Automobile manufactures are under thepressure to develop cars that do not pollute. One powerful motive is aCalifornialaw requiringthat by the year 2000, ten percent of the new car sales in the state beso-called zero-emission vehicles. These cars must put no pollutants whatsoeverinto the atmosphere.Californiais a huge market for the automobile companies, so they are working hard to meetthese standards. So far the electric car seems to be the best alternative. Sothe biggest advantage of electric cars is that they don't pollute. However,they will be in competition with gas-powered cars. And that's where theweaknesses come out. The big problem is that the batteries in electric carsweigh a lot relative to the amount of power they deliver. For instance, in oneelectric car, the batteries weigh four hundred kilograms and they provideenough energy to go 250 kilometers before recharging which take 8 hours. Comparethat to a moderately fuel efficient conventional car, it can go 600 to 700 kilometerson a tank of gas. And refilling takes just minutes. If there are other drainson an electric car's batteries besides a motor headlights, air-conditioning ora heater, its already limited range would be significantly reduced. So automobileengineers are trying to make more powerful batteries that would increase thecar's range and make them more attractive to buyers.
