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（符合標(biāo)準(zhǔn)） 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(jī)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 ＄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 do no harm to the environment，too.
    While some points make electric cars seem attractive，other points aren't as favorable.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）.
    An electric car has to stop more often to get recharged.Therefore，a gas car would be a better option（選擇）if you have far to drive.And electric cars aren't as convenient（方便的） to power up as gas cars are.
    There are plenty of gas stations，but not many charging stations for electric cars.Then，once an electric car reaches a charging station，it can take up to six hours to charge.
    There are certainly advantages to both electric cars and gasoline cars.It's good to know that there is a choice.Which one do you prefer？It's up to you.

※Introduction：With the appearance of electric cars，people wonder whether electric cars can reach the same standards as gasoline cars.	※（1） Similarity Similarity ：The looks of gasoline cars and electric cars
①For electric cars，having fewer parts cuts down the cost of their maintenance and the（2） possibility possibility of having problems in the machines. ②Compared with gasoline cars，electric cars are more energy saving，making them cheaper to operate. ③Compared with gasoline cars，electric cars are（3） friendlier friendlier to the environment. ④Gas cars can cover a（4） longer longer distance on a full tank than electric cars on a full charge. ⑤There are many gas stations built for gas cars while not enough charging stations are provided for people to charge their electric cars.

※Conclusion：Both gas cars and electric cars have their own advantages.Your choice depends on your （5）
