Question 26 to 30 are based on the following passage:
The United States is not the only country affected by
the "computer revolution". All the major countries of the
world have computers, and the developing countries are
increasingly aware that computers play a big part in their
economic advancement.
Usually what one sees is a machine that looks like a
typewriter; it is called a computer terminal.But computers
are also used in unseen ways. For example, they determine
how much time there should be between traffic signals to
prevent traffic problems and to keep millions of cars
moving in an orderly flow. When you buy an automobile, a
factory process that is controlled by a computer enables
you to obtain a car with your own choice of colors and
special features in just a few weeks time. In medical
laboratories, computers have reduced the errors in testing,
and they have saved doctors countless hour of work. Before
long, medical histories of all Americans will be kept in
computer "banks". If a person becomes ill far from home,
local doctors will be able to get his medical record
immediately. In science,the computer has performed in
minutes experiments which would have required thousands of
hours of work by human hand and minds.
Most experts agree that computers are essential to
solving the problems of increasing population,city living,
and public welfare. Without computers, the job of solving
these problems would require millions of workers to do tons
of paperwork. Before any computer can work on any problem,
however,it must be told what to do. Someone must program
the computer, step-by-step. At first this was done by
having the programmer write out his instructions in the
form of numbers which could be "understood" by the machine.
Within a short time, attempts were made to perfect a system
that would enable humans to conununicate more easily with
machines. Various "languages" were developed by means of
which the programmer could use words that had meanings for
him, and another program in the machine would translate the
words into the computers number system.
Without special training, it is impossible to
understand exactly how a computer does its
work.Nevertheless, many people without scientific training
use computers in their daily lives. In some American
schools, for example, young children are being taught by
computers for part of the school day.
The use of computers in schools has worried some
Americans. There are those who fear it will remove the
human element from teacher-student relationships. On the
other hand, there are educators who consider computer
program a valuable means of freeing teachers from the more
boring and tiring tasks, thus enabling them to spend more
time with individual students.
In education, as in business and industry, science
and medicine, computers play an important partin almost
every type of operation. The future will bring major
advances in computer technology and applications, which
will aid man in his efforts to improve his world.
