     Car sharing is another way to drive green which is gaining in popularity, especially in urban areas. People

who may not drive every day but still want a car to run errands (差事) or drive on weekends benefit most

from car sharing. Car sharing is usually run by a service like Zipcar, though there are non-profit (非营利的)

and informal car sharing services. Members pay a monthly fee and have access to an entire fleet of cars when

they need one. The cars are parked in fixed spots around the city, so members only need to make a reservation,

and then go to the pickup spot.

     Car sharing has major environmental benefits because it reduces the number of cars on the road. Members

don't drive just because they are in a car. They plan trips, and if they don't need a car, they don't use one. Still,

a car is available to them if they need to make a big trip to the grocery store, pick someone up at the airport or

if they want to go to the beach for the day. Members also benefit by having access to a car without any of the

headaches of ownership. They usually don't have to pay for the gas, insurance or maintenance (保养), and the

monthly membership fee is less than a typical car payment. So if you really want to go green but aren't ready to

totally give up a car yet, car sharing may be the way to go.

     If you still need to get around, but want to go even greener than sharing a car, share a bus!

如图所示，两个光滑的圆弧轨道竖直固定在水平地面上，轨道半径R相同。A轨道由金属凹槽制成，B轨道由金属圆管制成。在两轨道右侧的正上方分别将金属小球A和B由静止释放（两球均可视为质点），小球距离地面的高度分别用h_A和h_B表示，下述说法正确的是

A．若h_A=h_B≥2R，则两小球都能沿轨道运动到最高点

B．若h_A=h_B=，则两小球在轨道上升的最大高度均为

D．若欲使两小球沿轨道运动且从最高点飞出，则必须
