问题     What might driving on an automated highway be like? The answer depends on what kind of system is ultimately adopted. Two distinct types are on the drawing board. The first is a special purpose lane system, in which certain lanes are reserved for automated vehicles. The second is a mixed traffic system: fully automated vehicles would share the road with partially automated or manual driven cars. A special purpose lane system would require more extensive physical modifications to existing highways, but it promises the greatest gains in freeway capacity.
    Under either scheme, the driver would specify the desired destination, furnishing this information to a computer in the car at the beginning of the trip or perhaps just before reaching the automated highway. If a mixed traffic system was in place, automated driving could begin whenever the driver was on suitably equipped roads. If special purpose lanes were available, the car could enter them and join existing traffic in two different ways. One method would use a special on-ramp.
    As the driver approached the point of entry for the highway, devices installed on the roadside would electronically check the vehicle to determine its destination and to ascertain that it had the proper automation equipment in good working order. Assuming it passed such tests, the driver would then be guided through a gate and toward an automated lane. In this case, the transition from manual to automated control would take place on the entrance ramp. An alternative technique could employ conventional lanes, which would be shared by automated and regular vehicles. The driver would steer onto the highway and move in normal fashion to a "transition" lane. The vehicle would then shift under computer control onto a lane reserved for automated traffic.(The limitation of these lanes to automated traffic would, presumably, be well respected, because all trespassers could be swiftly identified by authorities.)
    Either approach to joining a lane of automated traffic would harmonize the movement of newly entering vehicles with those already traveling. Automatic control here should allow for smooth merging without the usual uncertainties and potential for accidents. And once a vehicle had settled into automated travel, the driver would be free to release the wheel, open the morning paper or just relax.
How to paraphrase "trespassers" in the last but one paragraph?
选项 A、Person who enter someplace without the owner’s permission or other authority.
B、Person who take advantage of something in a selfish way.
C、Person who use something unreasonably.
D、Person who do wrong.
答案A
解析 本题是词义题。作者认为，配有先进计算机监控系统的自动交通网络系统能够得以顺利运转。作者称这种假定是有根据的，因为任何试图非法驶入该系统的车辆，将很快被该系统监管当局通过计算机监控系统发现。“trespassers”有A、B、C和D 4个含义，联系上下文，只有A符合题意。
