Once it was considered good to keep the car engine idle a minute or two following cold stars. Today, with modern technology, the opposite is true. An engine operating under road conditions will warm up faster and run more efficiently than one that is idling. Idling just burns gas (on average, about a gallon an hour).
When you have a full tank of gas, park the car facing downhill is possible: this will prevent any gas from coming out of the tank. Parking in areas of less or no sunlight helps prevent the gas from steaming that would occur if you parked in the hot sun. Your car will stay cooler, too, and that means less gas consuming work for the air conditioner once the engine is started.
Stay away from wide-track tires if you want top mileage (耗油1升行驶的英里里程). Narrow-track tires produce less friction and thus rolling resistance. The same effect is achieved by adding three to five pounds above recommended pressure to each tire; while this won’t noticeably affect your car’s sliding quality, it will increase tire life and gas mileage.
Check tire pressure often, especially when the weather turns cold. The difference between winter and summer tire pressure can be as much as eight pounds. This could cost you two miles per gallon. [br] Wide-track tires .
选项
A、won’t noticeably affect your car’s sliding quality
B、can increase tire life
C、will increase rolling resistance
D、help attain top gas mileage
答案
C
解析
根据题干定位到文章第三段首句Stay away from wide-track tires if you want top mileage. Narrow-track tries produce less friction and thus rolling resistance.可知,如果你想同样汽油开的英里数更多一些的话,不要使用宽轮胎。窄轮胎产生的摩擦少因而地面阻力小。由此可知答案选C
