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.

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.

Successful businesses tend to continue
implementing the ideas that made them successful. But in a rapidly changing
world, ideas often become obsolete overnight. What worked in the past won't
necessarily work in the future. In order to thrive in the future, you must
constantly create new ideas for every aspect of your business. In fact, you must
continually generate new ideas just to keep your head above water. Businesses
that aren't creative about their future may not survive.
Although Bill Gates is the richest, most successful man on the planet, he
did not anticipate the Internet. Now he's scrambling to catch up. If Bill Gates
can miss a major aspect of his industry, it can happen to you in your industry.
Your business needs to continually innovate and create its future. Gates is now
constantly worried about the future of Microsoft. Here's what he said in a
recent interview in U.S. News World Report: "Will we be replaced tomorrow? No.
In a very short time frame, Microsoft is an incredibly strong company. But
when you look to the two-to-three-year time frame, I don't think anyone can say
with a straight face that any technology company has a guaranteed position. Not
Intel, not Microsoft, not Compaq, not Dell, take any of your favorites. And
that's totally honest." You may remember that in 1985 the
Cabbage Patch Kids dolls were the best-selling toy on the market. But after
Coleco Industries introduced their sensational line of dolls they became
complacent and didn't create any new toys worth mentioning. As a result, Coleco
went bankrupt in 1988. The most successful businesses survive in
the long term because they constantly reassess their situations and reinvest
themselves accordingly. The 3M Company has a 15% rule: employees are encouraged
to spend 15% of their time developing new ideas on any project they desire; it's
no surprise, then, that 3M has been around since 1902. Most
businesses are not willing to tear apart last year's model of success and build
a new one. Here's a familiar analogy to explain why they are lulled into
complacency: imagine that your business is like a pot of lobsters; to cook
lobsters, you put them into a pot of warm water and gradually turn up the heat;
the lobsters don't realize they're being cooked because the process is so
gradual. As a result, they become complacent and die without a struggle.
However, if you throw a lobster into the pot when the water is boiling, it will
desperately try to escape. This lobster is not lulled by a slowly changing
environment. It realizes instantly that it's in a bad environment and takes
immediate action to change its status.

单选题{{B}}Passage Three{{/B}}
In early 2004 eight tiny sensors were
dropped from a plane near a military base in California. After hit ting the
ground, the sensors—also known as smart dust sensors organized themselves into a
network and quickly detected a fleet of military vehicles on the ground. They
determined the direction, speed and size of a series of military vehicles
traveling along the road and later transmitted the data to a computer at a
nearby base camp. Smart dust sensors are minicomputers—as small
as a grain of rice in some cases—that can monitor and evaluate their physical
environment and can relay the information via wireless, communication. They can
monitor elements such as temperature, moisture, humidity, pressure, energy use,
vibration, light, motion, radiation, gas, and chemicals. These devices will soon
have many applications, such as use in emergency rescue.
Software has been developed to run these minicomputers. A key feature of
the software is the ability of the sensors to automatically organize themselves
into a communications network and talk to each other via wireless radio signals.
If any one connection is interrupted, the sensors will self-correct and pass the
information on to the next available sensor. Each sensor has a
chip that does the computing work recording things like temperature and motion
at its location. Each sensor also has a tiny radio transmitter that allows it to
talk to other sensors within 100 feet or so. With a single network of 10,000
sensors—thought to be the biggest array (排列) of sensors currently possible, you
could cover 9 square miles and get information about each point along the way.
The data finally works its way to a base station that can send the information
to a computer or to a wireless network. The scientists who are
working with this technology say smart dust sensors can be used to detect the
location or movement of enemy troops in areas too dangerous or remote for
soldiers to operate. Scattering hundreds of self-networking sensors from a
manned or unmanned plane onto the battlefield, in theory, could produce critical
information and lead to strategic advantage. Sensors could also be used to
detect the presence of chemical weapons and could give troops the time needed to
put on protective gear.
