The answer depends on what kind of sys tem 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 (高速公路) capacity.Under either scheme, the driver would specify the desired destination, furnishing this information to a puter in the car at the beginning of the trip or perhaps just before reaching the automated highway. If a mixed traffic system way 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 onramp (入口引道). 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 auto mated 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 puter control onto a lane reserved for automated traffic. (The limitation of these lanes to automated traffic would, presumably, be well respected, because all trespassers (非法進(jìn)入者) 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.21.

A special purpose lane system is probably advantageous in that ________.A) it would require only minor changes to existing highwaysB) it would achieve the greatest highway traffic efficiencyC) it has a lane for both automated and partially automated vehiclesD) it offers more lanes for automated vehicles（B）23. Which of the following is true about driving on an automated highway?A) Vehicles traveling on it are assigned different lanes according to their destinations.B) A car can join existing traffic any time in a mixed lane system.C) The driver should inform his car puter of his destination before driving onto it.D) The driver should share the automated lane with those of regular vehicles.（C）24. We know from the passage that a car can enter a special purpose lane ________.A) by smoothly merging with cars on the conventional laneB) by way of a ramp with electronic control devicesC) through a specially guarded gateD) after all trespassers are identified and removed（B）25. When driving in an automated lane, the driver ________.A) should harmonize with newly entering carsB) doesn’t have to rely on his puter systemC) should watch out for potential accidentsD) doesn’t have to hold on to the steering wheel（D）Passage FourQuestions 26 to 30 are based on the following passage.Taking charge of yourself involves putting to rest some very prevalent myths. At the top of the list is the notion that intelligence is measured by your ability to solve plex problems。 to read, write and pute at certain levels。 and to resolve abstract equations quickly. This vision of intelligence asserts formal education and bookish excellence as the true measures of self fulfillment. It encourages a kind of intellectual prejudice that has brought with it some discouraging results. We have e to believe that someone who has more educational merit badges, who is very good at some form of school discipline is “intelligent.” Yet mental hospitals are filled with patients who have all of the properly lettered certificates. A truer indicator of intelligence is an effective, happy life lived each day and each present moment of every day.If you are happy, if you live each moment for everything it’s worth, then you are an intelligent person. Problem solving is a useful help to your happiness, but if you know that given your inability to resolve a particular concern you can still choose happiness for yourself, or at a minimum refuse to choose unhappiness, then you are intelligent. You are intelligent because you have the ultimate weapon against the big .—Nervous Break Down.“Intelligent people do not have .’s because they are in charge of themselves. They know how to choose happiness over depression, because they know how to deal with the problems of their lives.You can begin to think of yourself as truly intelligent on the basis o
