单选题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 manually 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 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 (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 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 (非法进入者) 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.

单选题The competition among producers of personal computers is essentially a race to get the best, most innovative products to the marketplace. Marketers in this environment frequently have to make a judgement as to their competitors' role when making marketing strategy decisions. If major competitors are changing their products, then a marketer may want to follow suit to remain competitive. Apple Computer, Inc. has introduced two new, faster personal computers, the Mackintosh II and Mackintosh SE, in anticipation of the introduction of a new PC by IBM, one of Apple's major competitors. Apple's new computers are much faster and more powerful than its earlier models. The improved Mackintosh is able to run programs that previously were impossible to run on an Apple PC, including IBM-compatible (兼容的) programs. This compatibility feature illustrates computer manufacturers' new attitude of giving customers the features they want. Making Apple computers capable of running IBM computers and thus more popular in the office, where Apple hopes to increase sales. Users of the new Apple can. also add accessories (附件) to make their machines specialize in specific uses, such as engineering and writing. The new computers represent a big improvement over past models, but they also cost much more. Company officials do not think the higher price will slow down buyers who want to step up to a more powerful computer. Apple wants to stay in the high-price end of the personal computer market to finance research for even faster, more sophisticated computers. Even though Apple and IBM are major competitors, both companies realize that their competitor's computers have certain features that their own models do not. The Apple line has always been popular for its sophisticated color graphics (图形) , whereas the IBM machines have always been favored in offices. In the future, there will probably be more compatibility between the two companies' products, which no doubt will require that both Apple and IBM change marketing strategies.

单选题Because of its potential for cutting costs, the distribution step in the marketing process is receiving more attention. Distribution involves warehousing, transporting and keeping inventory of manufactured products. Take an everyday product like fabric softener. After it comes off the assembly line, it's packed in cartons and trucked to warehouses around the country. When orders come in from retailers, the fabric softener is delivered to supermarket shelves. This is distribution. Probably the most crucial area for controlling costs is inventory. Companies don't want to overproduce and have unsold stock of their product piled up in warehouses. Wholesale companies and large retail chains employ several techniques for inventory control. This is where the computer revolution really had an impact. Computerized information systems give precise and up-to-date accounts of inventory on hand. And the field of distribution offers good entry-level jobs for persons with training in computer programming or data processing. Overseeing the whole area of distribution is the distribution manager. This job is becoming increasingly important and can lead to an executive position.
