　　每日一练!专升本英语阅读理解练习(0613)

　　Once it was considered good to keep the car engine idling 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 the 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 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 your 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.

　　问题：

　　1.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

　　【参考答案】D

　　[考点]主旨大意题

　　【精析】D 根据第二段第二、三句“…prevent any gas from coming out of the tank…prevent the gas from steaming…”以及第三段最后一句“…it will increase tyre life and gas mileage.”等都可以看出文章提到最多的就是关于如何省油的问题，故四个选项中只有D项最符合文章的写作意图。

　　2.According to the passage, keeping the engine running idly .

　　A.will just waste gas

　　B.will warm it up more quickly

　　C.will make it work more efficiently

　　D.is necessary in cold weather

　　【参考答案】A

　　[考点]事实细节题

　　【精析】A 根据第一段最后一句“Idling just burns gas…”可知，空转只会浪费汽油。故选A。

　　3. Parking your car in a cool place .

　　A.will take it longer to warm up the engine

　　B.means less gas consumption for the air conditioner

　　C.prevents any gas from coming out of the tank

　　D.helps start your car more easily

　　【参考答案】B

　　[考点]事实细节题

　　【精析】B 根据第二段最后一句“Your car will stay cooler, too…”可知，当汽车停放在荫凉处时，车内会很凉快，所以会减少因开空调而消耗的油。故选B。

　　4. Wide-track tyres .

　　A.won't noticeably affect your car's sliding quality

　　B.can increase tyre life

　　C.will increase rolling resistance

　　D.helps attain top gas mileage

　　【参考答案】C

　　[考点]推理判断题

　　【精析】C 根据第三段前两句可知，想要燃油量少而行驶路程长就应该远离宽齿的轮胎，窄齿的轮胎摩擦力和转动时的阻力都很小。由此可推知，宽齿的轮胎产生的摩擦力和转动时的阻力都很大。故选C。

　　5.Tyre pressure changes .

　　A.in different weather conditions

　　B.when narrow-track tyres are used

　　C.in different road conditions

　　D.when wide-track tyres are used

　　【参考答案】A

　　[考点]推理判断题

　　【精析】A 根据最后一段第二句可知，轮胎压力在冬天和夏天会有多达8磅的差距。由此可推知，胎压是随天气状况而改变的。故选A。
