Car Maintenance
Once it was considered good practice to let the car engine idle a minute or two following cold starts. 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.(46).
When you have a full tank of gas, park the car facing downhill if possible; this will prevent any gas from coming out of the tank.(47). Your car will stay cooler, too, and that means less gas-eating work for the air conditioner once the engine is started.
(48). Narrow-track tires produce less friction and thus less rolling resistance. The same effect is achieved by adding three to five pounds above the recommended pressure to each tire, without exceeding 32 p. s. i.; while this won't noticeably affect your car's riding quality, it will increase tire life and gas mileage.
Check tire pressure often, especially when the weather turns cold.(49). This could Cost you two miles per gallon.
Fuel-economy tests show that radial tires improve gas mileage. A car that gets 15 miles per gallon with conventional tires would get 16 miles per gallon with radials.
Snow tires should be fixed no sooner than necessary and removed as soon as weather permits.(50),and you pay a one-to-three-mile-per-gallon loss when you have "snows" on.
A Stay away from popular widetrack tires if you want mileage
B Idling just burns gas(on average, about a gallon an hour)
C They commonly are harmful to other parts of the car
D They generate more rolling resistance than conventional tires
E Parking in areas of less or no sunlight helps prevent the gas from steaming that would occur if you parked in the hot sun
F The difference between winter and summer tire pressures can be as much as eight pounds
When you have a full tank of gas, park the car downhill. 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 tyres if you want top mileage (汽车耗费1加仑油所行驶的路程) . Narrow-track tyres produce less friction and thus less rolling resistance. The same effect is achieved by adding three to five pounds above recommended pressure to each tyre: while this won't noticeably affect you car's sliding quality, it will increase tyre life and gas mileage.
Check tyre pressure often, especially when the weather turns cold. The difference between winter and summer tyre pressure can be as much as eight pounds. This could cost you two miles per gallon.
The main purpose of the passage is to tell us______.
A．how to drive faster
B．how to drive a car properly
C．how to make a car run smoothly
D．how to make your car consume less gas
If possible,when you have a full tank of gas,park the car facing downhill,as this will prevent any gas from leaking out of the tank.Parking in areas of little or no sunlight helps prevent evaporation(蒸发)of the gas which would occur if you parked in the hot sun.Your car will stay cooler,too,and this means less gas is consumed for the air conditioner once the engine is started.
Stay away from wide-track tires if you want top mileage for your dollar.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 mobility,it will increase the life of your tires and gas mileage.

听力原文： Many people tend to disregard the exhaust system of an automobile. They may think that the exhaust system does nothing more than to discharge the waste products of the combustion process. Although this is exactly what the exhaust system does, the way these waste product is discharged out of the engine is essential to the performance of the engine. A gasoline engine involves three processes: combustion, mechanical drive and exhaust. If one of these processes is impeded, the condition of the engine will depreciate. The exhaust system has three major functions, the first of which is to channel out the waste products of combustion out of the engine to allow it to continue to burn fuel unhindered thereby ensuring that the engine runs smoothly. An efficient exhaust system allows the waste gas and compound to escape quickly out of the system. If these waste products do not escape from the engine immediately, they may choke up the engine thus causing it to break down. Another function of the exhaust system is to reduce the noise generated by the engine. The third function of the exhaust system is to clean up the emissions that are harmful to the environment. When the engine burns fuel, it produces gases that pollute the air such as hydrocarbons, carbon monoxide and nitrogen oxides.
What is the passage mainly about？
A．The exhaust system of a car.
B．Waste gas.
C．The car engine.
D．Air pollution.
