Sports account for a growing amount of income made on the sales of commercial time by television companies. Many television companies have used sports to attract viewers from particular sections of the general public，and then they have sold audiences to advertisers.

An attraction of sport programs for the major U.S. media companies is that events are often held on Saturday and Sunday afternoons―the slowest time periods of the week for general television viewing. Sport events are the most popular weekend programs，especially among male viewers who may not watch much television at other times during the week. This means the television networks are able to sell advertising time at relatively high prices during what normally would be dead time for programming.

Media corporations also use sports to attract commercial sponsors that might take their advertising dollars elsewhere if television stations did not report certain sports. The people in the advertising departments of major corporations realize that sports attract viewers. They also realize that most business travelers are men and that many men make family decisions on the purchases of computers， cars and life insurance.

Golf and tennis are special cases for television programming. These sports attract few viewers， and the ratings(收视率)are unusually low. However, the audience for these sports is attractive to certain advertisers. It is made up of people from the highest income groups in the United States，in?cluding many lawyers and business managers. This is why television reporting of golf and tennis is sponsored by companies selling high-priced cars,business and personal computer, and holiday trips. This is also why the networks continue to carry these programs regardless of low ratings.

Advertisers are willing to pay high fees to reach high-income consumers and those managers who make decisions to buy thousands of "company cars" and computers. With such viewers，these programs don, t need high ratings to stay on the air.

Pretoria, South Africa. Hundreds of swimmers are playing in the water along a South African beach. Suddenly a huge shark appears offshore and heads for the bathers. Before it can get close to the swimmers, the shark, for some mysterious reason, starts swimming parallel to the beach. Then it turns away from the shore and heads out to sea,leaving the swimmers untouched.

Such a scene will soon become common along shark infested(鲨鱼出没)shores. An electrical engineer from the University of Pretoria has developed an electrical system that repels(击退)sharks by controlling their movements. Confixsed by this action, the sharks end up turning away from the beach.

In this unusual shark repellent method, an insulated(绝缘的)cable is buried on the bottom of the sea around a beach from which people swim. When an electric current is sent through the cable， an electric field is produced in the water above the cable.

When the shark swims into the electric field, nerve cells just below the shark's skin detect the field. The electricity produces a reflex(反射)action in the shark's muscles, causing the dangerous animal with sharp teeth to swim parallel to the cable. Confused by increasing loss of control of its muscles, the shark suddenly changes its direction and heads seaward, away from the electric field.

In a test of the invisible new shark-repellent system，a cable was placed around a beach in St. Lucia,an island in the tropics. A protective net,which had been installed around the beach a long

time ago to keep sharks from swimmers, was left in place during the experiment.

When the electric field was left on for more than a year and a half,no sharks were found in the nets. However, when the power was turned off, 89 sharks ended up in the nets.

of many sharks，say biologists. Currently，thousands of sharks die each year when they become trapped in protective nets that surround holiday resorts in Africa and Australia. About 10 to 15 humans are killed by sharks annually.

When a cat is frightened,its heart starts beating faster,its muscles get tense, and there are changes in the chemicals in its blood stream. If the danger continues, it will defend itself,or it will run away as fast as possible.

Something like this also happens to people. When we are excited, angry，scared or arousedf激起感情)by others' emotions, our bodies go through many physical changes, all of which make us more alert(警惕的)and ready to react. We also get ready to defend ourselves or run. Human beings,however,have a problem that animals never face. If we give way to our feelings and let them take over，we can get into trouble. Have you ever said something in anger―or hit somebody―and regretted it later? Have you ever shouted at a teacher,told somebody you were lonely, or said you were in love,and then wished later you had kept your mouth shut? It isn't always wise to express your feelings freely.

Does this mean that it，s smarter always to hide our feelings? No！If you keep your feelings  of anger, sadness, and bitterness hidden away or bottled up(掩饰)inside, your body stays tense. Physical illnesses can develop, and you can feel disturbed badly inside. It can actually be bad for your health.

You can try to treat emotions as if they were bananas in the cupboard. You can hide them and you can pretend they don't exist,but they'll still be around. And at last you'll have to deal with them,just like those bananas.
