[单项选择]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
A. will take it longer to warm up the engine
B. means less gas consumption for the air conditioner
C. prevent any gas from coming out of the tank
D. helps start your car more easily

[单项选择]

AMERICA’S central bank sent a clear message this week. For the second consecutive meeting, the Federal Open Market Committee, the central bank’s policy-making committee, left short-term interest rates unchanged at 1.75%. But it said that the risks facing the economy had shifted from economic weakness to a balance between weakness and excessive growth. This shift surprised no one. But it has convinced many people that interest rates are set to rise again--and soon.
Judging by prices in futures markets, investors are betting that short-term interest rates could start rising as early as May, and will be 1.25 percentage points higher by the end of the year. That may be excessive. Economists at Goldman Sachs, who long argued that the central bank would do nothing this year, now expect short-term rates to go up only 0.75% this year, starting in June. But virtually everyone reckons some Fed tightening is in the offing.
The reason After an unprecedented 11 rat
A. Short-term interest rates should be guarded wisely
B. Unemployment no longer constitutes a problem
C. A sustainable recovery depends on corporate profits
D. Too much caution might suspend economic growth
