A young man was recently murdered in an apartment in Taipei. The police found no clues
except for one fingerprint on the wall. Usually, finding the owner of a fingerprint would take several
days or even months because there are millions of fingerprints in the files. In this case, however, the
police found the murderer in just a few hours because they had a powerful helper — a computer.
The computer compared the fingerprint on the wall with all the fingerprints in the files and told the
police whom the fingerprint belonged to.
Computers can store large amounts of information. In a few seconds, they can give us the
information stored in them. In one second, computers can do millions of calculations. Through the
computer network, we can send information to a faraway place in a moment.
Computers are used in many other situations today. At home, we use small, simple computers
to control the washing machine or the microwave oven. At the supermarket, computers read the
labels on products and work out the bills. In the library, a computer can tell you, in a second, if a
book is there. Many schools use computers to teach students. People may even use computers to
make friends on the BBS.
Many people believe that computers will become as smart as or even smarter than human
beings and that they will do everything for us. If this happens, what will you do to pass the time?
Don’t worry. You’ll have a lot of computer games.
【題組】42. Why could the computer help the police find the murderer so fast?
(A) Because it could read the labels on products.
(B) Because it helped the police find the person to whom the fingerprint belonged.
(C) Because it had a lot of games.
(D) Because it could calculate very quickly the number of fingerprints stored in the files.
