A mobile phone is in fact a small radio.A radio sends a person’s voice over a long way to another radio.A voice that is sent by radio is called a signal.A radio signal travels very quickly.

　 Only a few years ago，mobile phones were very large.They needed large batteries.They had to be powerful to send their signal to faraway places.This was because most cities had only one antenna tower for mobile phones.

　 Today’s mobile phones are small and easy to use.Now most cities have a lot of antenna towers，not just one.This means that each mobile phone doesn’t have to send its signal far away，so they don’t need to be so powerful.Mobile phones today use small batteries.A large city，where lots of mobile phones are used，can have hundreds of towers.

　 Do you know what use a mobile phone has? Yes，you can use it to do a lot of things.

　 Call your friends and family from almost anywhere.

　 Call the police immediately if there is an accident in the street.

　 Send or receive messages.

　 Sending short written messages is a popular way to use your mobile phone.Many people use short forms of words，so the messages are quick to write and read.Can you guess what these messages mean? Try reading them out.What do you hear?

　 RUOK?

　 Will I C U B4 2moro?

Word came that the government must control the spread of this disease.

“Our job，”said the　26　officer，“is to spray the wall of every house in every town and village in the malaria parts of Mexico.You may be　27　to learn that there are about ninety-nine thousand　28　villages and towns.Some are big places like the capital city，　29　are single houses deep in the forest or upon the mountaintops.The men working with our program say that most of these people　30　within districts which are　31　enough for the mala ria-carrying mosquitoes to live in and spread the disease.That　32　that we must plan to spray the bricks of　33　three million houses once or twice a year for five years.”

“We have　34　everything very carefully，”said the officer　35　.“Our advance guards have drawn　36　of some forty thousand parts of the country for　37　by the spray teams.Each house in the malaria districts has been given a special　38　so that we can work in order.The United States has given us cars and trucks to carry the spray teams and their　39　.”

“The malaria program has been　40　with the people in this country.Everyone wants to　41　.The Defense Department is helping us plan the　42　of men and supplies.The Education Department has printed sheets in Spanish to explain　43　malaria is spread.Resistance is a problem.It was in the neighboring country—the United States that such resistance to spray was first　44　.Take the　45　of the housefly and D.D.T. At fist D.D.T. killed them off.Now it won’t hurt a fly.”

“What worries people is the danger that the mosquitoes may become resistant，”said the officer at last.

No country in the world has more daily newspapers than the USA.　There are almost 2000 of them，as compared with 180 in Japan，164 in Argentina and 111 in Britain.　The quality（质量） of some American papers is quite high and their views are used all over the world.　Excellent newspapers like the Washington Post or the New York Times　have a powerful influence（影响） all over　the country.　However，the Post　and the New York Times　are not national newspapers in the sense that The Times is in Britain of Le Monde is in France，since each American city has its own daily newspaper.　The best of these give detailed（详细的）accounts of national and international news，but many tend to limit themselves to state or city news.?

Like the press（报刊） in most other countries，American newspapers report news from the “exciting” and “relaxing” to the serious.　They try to entertain people as well as give information，for they have to compete with the attraction of television.

Just as American newspapers try to satisfy all tastes，they also try to attract readers of all political parties.　A few news papers support extremist（极端主义者） groups on the far right and on the far left，but most daily newspapers try their best to attract middle-of-the-road Americans who are mainly moderate（温和的）.Many of these papers print materials by well?known journalists of different political and social views，in order to give a balanced picture.?

As in other countries American newspapers can be either responsible（负责任的） or irresponsible，but it is generally accepted that the American press serves its country well and that it has more than once exposed political scandals（丑闻），for example，the Watergate Affair（水门事件）.?
