Can animals be made to work for us
Some scientists think that one day animals may be trained to do a number of
simple jobs that are now done by human beings.
They point out
that at a circus, for example, we may see elephants, monkeys, dogs and other
animals doing quite skillful things. Perhaps you have seen them on the
television or in a film. If you watch closely, you may notice that the trainer
always gives the animal a piece of candy or a piece of fruit as a reward. The
scientists say that many different animals may be trained to do a number of
simple jobs if they know they will get a reward for doing them.
Of course, as we know, dogs can be used to guard a house, and soldiers in
both old and modem times have used geese to give warning by making a lot of
noise when a stranger or an enemy comes near. But it may be possible
A. Animals are very skillful at a circus.
B. They are big and strong.
C. Some animals arc as clever as human beings.
D. Animals can be trained because they like to get something as a reward.

People can be addicted to different things — e.g.
alcohol, drugs, certain foods, or even television. People who have such addition
are compulsive, i.e. they have a very powerful psychological need that
they feel they must spend money. This compulsion, like most others, is
irrational — impossible to explain reasonably. For compulsive spenders who buy
on credit, charge accounts are even more exciting than money. In other words,
compulsive spenders feel that with credit, they can do anything. Their pleasure
in spending enormous amounts is actually greater than the pleasure that they get
from the things they buy.
