Cars powered by gasoline（汽油）were sold for many years before cars that use electricity.Car companies are now making cars that are fully powered by electricity only.How do these electric cars measure up to traditional gasoline cars？
    Electric and gasoline cars look similar on the outside.They have very different parts under their hoods（引擎蓋），though.Electric cars have one main moving part：the motor.But gasoline cars have hundreds of parts，often requiring frequent maintenance（保養(yǎng)）.Having fewer parts makes the electric car cheaper to maintain and less likely to have mechanical（機械的）problems.
    Electric cars are energy efficient（高效的），also making them cheaper to operate.It costs about ﹩1.00 to travel 43 miles in an electric car.But it costs about S 1.25 to go 18 miles in a gasoline car.Basically，an electric car can go twice as far as a gas car for the same price.
    Electric cars do not have tailpipe emissions（尾氣排放），making them more friendly to the environment，too.
    While some details make electric cars seem attractive，other details aren't as favourable.For example，some electric cars can travel only 60 to 120 miles on a full charge（充電）.Most gas cars can drive hundreds of miles on a full tank（油箱）.
    There are certainly advantages to both electric cars and gasoline cars.It's good to know that there is a choice.

Electric Cars VS Gasoline Cars
Introduction	With the appearance of electric cars，people wonder whether electric cars can achieve the same standards as gasoline cars.
（1） Similarity Similarity	Electric cars and gasoline cars look similar on the outside.
Differences	Electric cars： Having fewer parts reduces the cost of their maintenance and the （2） possibility possibility of having mechanical problems. （3） Compared Compared with gasoline cars，electric cars are more energy saving，making them cheaper to operate. Having no tailpipe emissions，they are more environmentally（4） friendly friendly . Gasoline cars： Gas cars can cover a（5） longer longer distance on a full tank than electric cars on a full charge.
Conclusion	Both electric cars and gasoline cars have their own advantages，which provides people with a choice.
