Section A Questions 47 to 51 are based on the following passage.
Motorways are no doubt the safest roads in the country. Mile for mile,
vehicle for vehicle you are much less likely to be killed or seriously injured
than on an ordinary, road. On the other hand, motorways have a far better
accident record than any other part of our national road system because of the
speed and volume of traffic. If you do have a serious accident on a motorway,
fatalities are much more likely to occur than in a comparable accident elsewhere
on the roads. It is reported that motorway accidents account for some 10% of all
injuries out side urban areas. Motorways have no sharp, bends,
no roundabouts or traffic lights and thus speeds are much greater than on other
roads. Though the 70 m.p.h, limit is still in force, it is often treated with
the contempt that most drivers have for the 30 m.p.h, limit applied in built-up
areas in Britain. Added to this is the fact that motorway drivers seem to like
traveling in convoys with perhaps barely ten meters between each vehicle. The
resulting horrific pile-ups involving maybe hundred vehicles when one vehicle
stops for some reason—mechanical failure, driver error and so on—have become all
too familiar through pictures in newspapers or on television. How many of these
drives realize that it takes a car about one hundred meters to brake to a stop
from 70 m.p.h. Drivers also seem to think that motorway driving gives them
complete immunity from the caprices (多变)of the weather. However wet the
road, whatever the visibility in mist or fog, they plough at ludicrous
(滑稽的) speeds oblivious (不以为然的) of police warnings or speed restrictions
until their journey comes to a premature conclusion. Perhaps one
remedy for this motorway madness would be better driver education. Twenty eight
per cent of the motorcyclists polled for National Motorway Month wanted
motorists to receive formal training in motorway driving before being allowed
down a slip road. At present. learner drivers are barred from motorways and are
thus as far as this kind of driving is concerned, thrown in at the deep end.
However much more efficient policing is required of, it is the duty of the
police not only to enforce the law but also to protect the general public from
its own folly. According to the last paragraph, what measure should be taken to keep driver’s madness in good control
