Passage Two

Hair loss is one of those things we still do not understand. Science has， of course， shown that men are more likely than women to suffer major hair loss. Some kinds of hair loss are temporary （暂时的）， an effect of illness. In those cases we can expect the hair to grow back.

It all depends on whether the hair root is alive. If it is not， hair loss is permanent and nothing will help.

Some daily loss of hair is a normal， healthy sign. Most people lose between 40 to 50 scalp hairs each day.

Each of these scalp hairs grows for from two to six years and then rests. About three months later it is pushed out by a new hair growing from the same root.

This is not something that should cause great concern.

Something else we know is that normal hair loss is seasonal， with the most hair loss occurring in the fall. Everyone experiences a normal cycle of loss and growth.

The problem of hair loss results when loss is greater than growth.

The main cause of hair loss in men seems to be accumulation （ 积累） of a hormone（ 荷尔蒙） in the body. When that hormone reaches a certain level， the hair growing period is shortened and hair loss is the result. This is no cure for most cases of hair loss. This， however， is not the end of the world.

Passage One

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 to train animals to work in factories. In Russia， for example， pigeons which are birds with good eyesight， are being used to watch out for faults in small steel balls that are being made in one factory. When the pigeon sees a ball which looks different from others， it touches a steel plate with its beak. This turns on a light to warn people in the factory. At the same time a few seeds are given as a reward. It takes three to five weeks to train a pigeon to do this and one pigeon can inspect 3 000 to 4 000 balls an hour.

Apes have been used in America in helping to make cars， and scientists believe that these large monkeys may be one day gather crops and even drive trains.
